A twisting device and a twisting machine using the same

technical field

The invention belongs to the field of textile equipment, and in particular relates to a twisting device (“twisting device” in English) and a twisting machine (Twisting Macine) using the twisting device.

Background technique

In the textile industry, a single yarn is usually required to be twisted before the yarn is used for spinning. Twisting is to wind and twist two or more single yarns into a single yarn. In a broad sense, in the spinning process, the yarn (beard, yarn, thread, silk) is twisted and twisted or axially wound around its axis, so that the yarn is "twisted" or wrapped. for "twist". Twisting can make the fiber and the fiber or the monofilament and the monofilament cohesion and entanglement without loosening or slipping off, and has certain physical and mechanical properties (such as strength, elongation, elasticity, etc.) and appearance characteristics (such as luster, hairiness, feel, etc.). At present, the main twisting equipment mainly includes "double twister" and "ring spinning frame". The name of the double twisting machine comes from a kind of spindle (“spindle” in English) twisting device it uses, which can realize the twisting effect of “one turn and two twists” for the fed parallel multiple strands, except for the spindle twisting device. In addition, the double twisting machine also includes a collection and winding device that actively draws and collects the multi-strand wires twisted and output from the spindle twisting device and then winds them into multi-strand bobbins. The collection and winding device usually includes a A roller that continuously rotates ("Roller" in English, "roller" in Chinese) or includes a pair of rollers that are close together and rotate in opposite directions, the rollers are commonly referred to in the textile industry as "winding rollers". ". The spindle twisting device used in the ring spinning frame is different from the double twister, which can only achieve the twisting effect of one turn and a single twist, including the spindle that drives the central tube of the cop to rotate continuously, and the roving that pulls the raw material for continuous rotation and twisting. The ring spinning frame spindle twisting device, including the traveler and the "ring" of the traveler's rotating orbit, is used to twist the raw roving into a spun yarn and wind it into a cop, after which the multiple cops will be placed on the winder The connection becomes the final product package.

As shown in the sub-figure (A) of Figure 1, the traditional twisting process carried out by the double twister is divided into two processes: "twisting" and "twisting". A right arrow in the sub-figure (A) of Figure 1 The so-called "doubling" process is shown on the left and the "twisting" process is shown on the right side of the arrow. As shown in the “yarn doubling” process on the left side of the arrow in the figure, “yarn doubling” is to combine the single-strand yarns 2 from different single-strand bobbins 1 into parallel multi-strand yarns 3 and wind them into parallel multi-strand yarns. Spool 4. The principle is very simple, just let all the single strands 2 pass through a common channel and then directly wind them into parallel multi-strand bobbins 4, and the parallel multi-strand bobbins 4 produced after the yarn are combined are used as the next " The raw material for the "twisting" process. As shown in the twisting process on the right side of the arrow in the sub-figure (A) of FIG. 1 , the parallel stranded wire 3 on the parallel stranded bobbin 4 is usually rotated and unwound from the parallel stranded bobbin 4 to be fed. The spindle twisting device of the double twister is rotated and twisted to generate the twisted multi-stranded wire 5, and then the twisted multi-stranded wire 5 after "twisting" is added from the spindle twisting device through the winding roller 12. The twisting process is completed by pulling it out and winding it into a twisted multi-strand bobbin 6 . The parts indicated by the reference numeral 7 and its lead wires and arrows in the sub-figure (A) of FIG. 1 are the “spindle” and the spindle twisting device of the above-mentioned double twisting machine, and the black arc-shaped solid arrow in the figure indicates the spindle 7 will keep spinning during the twisting process. In addition, the sub-figure (A) of FIG. 1 also shows the transverse yarn guide device that forms a regular-shaped yarn tube commonly equipped with twisting machines with reference numeral 13. In the sub-figure (A) of FIG. The arrows in the two winding rollers 12 indicate the rotation directions of the two opposite rotations. In fact, the two winding rollers 12 unwind the entire multi-strand wire from the parallel multi-strand spool 4 and pass the The power source for the continuous traveling of the spindle twisting device, in reality, a continuous rotating drum is often used as the winding device to pull out the multiple strands in the spindle twisting device of the double twister and wind it on the fastening suit. The bobbins on the rollers, at that time, between the transverse yarn guiding device 13 and the spindle twisting device often let the multi-strand threads pass through a spool ring 14 as shown in FIG. 2 . The hub 14 is also often referred to as a "yarn guide hook" in practice. The bidirectional arrows next to the lateral yarn guide device 13 in the sub-figure (A) of FIG. 1 indicate that the lateral yarn guide device 13 draws the twisted multi-ply yarns along the axial direction of the twisted multi-ply bobbin 6 Move back and forth regularly. In fact, the yarn doubling process on the left side of the sub-figure (A) of FIG. 1 is also equipped with the winding device and the transverse yarn guide device, and is omitted for the sake of brief description. FIG. 2 shows the principle that the spindle twisting device of the double twister performs rotational twisting on the parallel multi-strand wires 3 . As shown in FIG. 2 , the parallel multi-strand bobbins 4 are inserted on the cylindrical hollow spindle 7 in the hollow spindle tank 701 of the spindle device, and the cylindrical hollow spindle 7 is connected to the center of the bottom center of the hollow spindle tank 701. The openings are connected, and the hollow ingot pot 701 is sleeved on a twisting disc 8 below the hollow ingot pot 701 through the hole in the center of the bottom of the hollow ingot pot 701, and the parallel multi-stranded wire drawn from the parallel multi-stranded wire drum 4 is unwound. 3. First enter the interior of the hollow spindle 7 from above, then bend downward and then enter a horizontal transverse channel 802 inside the twisting disc 8, where the so-called "transverse channel" as shown in FIG. 2 refers to There is an included angle between the transverse channel 802 and the inner channel of the hollow spindle 7, usually the included angle is a right angle of 90 degrees; as shown in FIG. An integral coaxial transmission shaft 803, the twisting disc 8 is mounted on the twisting disc bracket 11 and can freely rotate around its own axis, the transmission shaft 803 and the transmission belt 10 (also commonly known as "" Dragon belt”) is attached and rotated under the frictional transmission of the transmission belt 10 (shown by the black solid straight arrow at the bottom of FIG. 2 is the movement direction of the dragon belt), thereby driving the twisting disc 8 to rotate continuously ( As shown by the black solid arc arrows on both sides of the twisting disc 8 in Fig. 2 ), usually the rotation axis of the twisting disc 8 and the axis of the inner channel of the hollow spindle 7 are located in the same straight line direction , as shown by the vertical dot-dash line in the enlarged area in the upper right corner of Fig. 2; as shown in Fig. 2, the multi-strand wires output from the transverse channel 802 inside the twisting disc 8 will be twisted by the spindle twisting device The upper winding device represented by a pair of winding rollers 12 is pulled upward to move (as shown by the single-line arrow at the top in Figure 2), in order to save space, the upper part of Figure 2 is omitted from Figure 1 (A) Shown are transverse yarn guides 13 and twisted multi-ply bobbins 6 forming regularly profiled bobbins. As shown in FIG. 2 and referring to the sub-graph (A) of FIG. 1 , due to the traction of the multi-strand wire by the collecting and winding device represented by a winding roller 12 above the spindle twisting device, the multi-strand wire exists everywhere. Axial tension, and because the transverse channel 802 in the twisting disc 8 and the inner channel of the hollow spindle 7 are not in the same linear direction, the multi-strand wires are bent from top to bottom from the inside of the hollow spindle 7. When entering the transverse channel 802 in the twisting disc 8, it will be bent and will closely abut against the bend 801 in the twist disc 8, due to the axial tension of the multiple strands on both sides of the bend 801. The resultant force will exert pressure on the bending 801 position, so the bending 801 position of the twisting disc will produce a corresponding reaction force on the multi-strand wire, which is equivalent to the bending 801 will produce a multi-strand wire. The radial clamping force, in fact, for any end of the multi-strand wire with axial tension, as long as the bending occurs, the multi-strand wire will have a clamping effect at the bend. At that time, because the twisting disc 8 was continuously rotated around the axis of the inner channel of the hollow spindle 7 and the axis of the twisting disc 8 driven by the lower transmission belt 10, the twisting disc 8 The rotation can make the multi-strands unwound from the parallel multi-strand spool 4 to be twisted and twisted back. In fact, this twisting process is equivalent to pinch the multi-strands at the bend 801 with fingers and make them twist. Rotate around the axial direction of the multi-stranded wire to form a twist; as shown in FIG. 2, since the multi-stranded wire bypasses the position of the bending 801 and then enters the transverse channel 802 of the twisting disc 8, Therefore, with the rotation of the twisting disc 8, the multi-strand yarns from the position of the bending 801 to the collecting and winding device represented by the pair of winding rollers 12 will also be twisted, thereby realizing "one turn". Two twist" function. In order to distinguish the twisted strands before and after the bending 801 position, the reference numeral 501 is used in FIG. 2 to mark the twisted strands before the bending 801 position, which is referred to in this specification as Named "pre-twisted multi-stranded wire", while using reference numeral 502 to mark the multi-stranded wire that is re-twisted after the position of the bend 801, it is named "post-twisted multi-stranded wire in this specification" ". As shown in FIG. 2 , the post-twisted multi-stranded wire 502 output from the transverse channel 802 of the twisting disc 8 (a part of the post-twisted multi-stranded wire 502 in FIG. 2 omits the spiral figure and is schematically represented by a double-dot chain line) , the single-line arc arrow in the double-dot chain line indicates that the post-twisted multi-strand wire 502 will be pulled upward while rotating) and will surround the rotation axis of the twisting disc 8 (that is, the hollow spindle 7). The axis line) is rotated to generate a commonly known "balloon" between the outlet of the transverse channel 802 of the twisting disc 8 and the hub 14 before the winding device as shown by the single-line arc arrow in the middle of FIG. 2 The air ring 9 surrounds the entire parallel multi-strand bobbin 4 and its container hollow ingot 701 with the rotation axis of the twisting disc 8 as the center. Sub-picture (C) of Figure 1 shows the twisting principle of "one-turn, two-twist" of the spindle twisting device of the aforementioned double twister in a concise and abstract form. Sub-picture (C) of Figure 1 and (D), (E) ) subfigures all use a hollow line and a solid thick line to refer to the two yarns that make up the multiple strands. As shown in sub-figure (c) of Figure 1, a stranded wire is bent after being unwound from the bobbin indicated by the lead number 4 to produce a radial clamping of the stranded wire Forced and pulled to the winding device indicated by the lead wire with reference numeral 12, with the rotation of the bend of the multi-strand, two sections of the pre-twist multi-line 501 and the post-twist multi-line are added. The twisted multi-strand line, the dotted ellipse and the arrow on it and the hollow arc-shaped arrow in sub-picture (C) indicate the rotation trajectory at the bend 801 of the multi-strand line, compared with a horizontal arrow in sub-picture (C) left and right The twisting effect of the multiple strands on both sides shows that the twisting directions of the multiple strands before and after bending 801 are the same, so one rotation of the bending point 801 can unwind from the yarn drum. Two twists are applied to the strands drawn between the take-up winding means indicated by a pair of winding rollers 12 . Referring to FIG. 2 , since the post-twisted multi-strand wire 502 will rotate to generate the aforementioned balloon 9 in reality, the reference numeral 9 is attached after the reference numeral 502 in the sub-figure (C) to show the actual formation of the balloon 9. balloon.

Figure 1 (b) subgraph shows the twisting principle of a conventional ring spinning frame. The "spinning" process in which the roving of the ring spinning frame is twisted and produced on the left side of the right-hand horizontal arrow in the figure is drawn from the roving bobbin 4' under the pulling of a pair of winding rollers 12. It is unwound and pulled by the traveler 15 and continuously rotates along the ring 16 to twist the roving between the traveler 15 and the winding roller 12 to form a spun yarn 5', and the spun yarn 5' is pulled by the traveler 15 for rotation. While moving, it is wound on a tube 17 to form a bobbin, which is also referred to as a "bobbin". After that, through the "winding" process shown on the right side of the right horizontal arrow in the sub-figure (B), the spun yarns wound on a plurality of fine cops are connected together and wound into a tube of a thick final finished spun yarn. Yarn 6'. The reason why the winding process is set is on the one hand because the more spun yarns are wound on the rotating bobbin 17, the greater the power consumption required to drive the bobbin 17 to rotate, on the other hand, it is also to ensure that the spun yarn 5' is applied The uniformity of the twist is improved, because the outer diameter of the tube 17 becomes larger after multiple layers of spun yarns are wound on the tube 17, resulting in a decrease in the linear speed of the winding spun yarn under the same rotational angular velocity. Note that the stranded wire (here, the roving 5 ′) fed from the winding roller 12 to the traveler 15 is bent at the traveler 15 , and at the tube 17 . Under the action of the winding tension of the multi-strand wire formed by the rotation, the multi-strand wire is subjected to radial clamping force at the bending of the traveler 15, which is the same as the multi-strand wire in the aforementioned double twisting machine. The same is true for the clamping force. The principle of rotation and twisting of the ring spinning frame is equivalent to pinching the roving at the traveler 15 with fingers and rotating around the multi-stranded wire clamping output port of the winding roller 12, so that the output from the winding roller 12 can be adjusted. The twists are applied to the multiple strands so that they are twisted to form spun yarns, and the number of twists applied to the rovings per unit time is related to the rotational speed of the traveler and the output speed of the rovings of the winding roller 12 . The (D) and (C) sub-pictures in Figure 1 show the twisting principle of ring spinning using two single-strand bobbins 1 as raw materials. The arc-shaped arrow indicates the rotation direction of the traveler 15 along the ring 16, and the upper arc-shaped arrow indicates the winding rotation direction of the tube 17. It can be seen from the sub-figure (D) that the multi-strand wire is actually The traveler 15 clamps and pulls around the clamping output port of the winding roller 12 to rotate so as to be subjected to a twisting operation to form the twisted multi-stranded wire 5, and the twisted multi-stranded wire 5 is immediately after twisting. It is wound and collected on the spool 17. Note that the twisting principle of the roving in the ring spinning apparatus shown in sub-figure (B) is consistent with the twisting principle of the multi-strand yarn shown in the sub-figure (D). As shown in sub-figure (e), the principle of ring spinning twisting is actually equivalent to using a winding device represented by a pair of winding rollers 12 to pinch the upper end of the multi-stranded wire, and the lower end of the multi-stranded wire is wound. On the bobbin of the cop and the continuous rotation of the cop around the multi-ply output opening of the winding device produces a twist, while the bobbin of the cop is still rotating and twisted. Multiple strands of wire are wound on it, and when the tube 17 rotates once, the traveler 15 also pulls the roving and rotates along the ring 16 and applies a twist to the roving, so the ring spinning frame can Roving or multi-strand yarn realizes the twisting effect of "one turn and one twist". (E) the reference numerals "15, 17" in the sub-figure and the cop indicated by its lead line refer to the cop that represents the role of the traveler 15 and the tube 17 in the (D) sub-figure, (E) The dotted ellipse in the figure and the arrow and the arc arrow on it indicate the rotation direction of the bobbin, and the reference numeral 16 in the figure indicates the rotation track of the bobbin, which is the steel in the (D) sub-figure. The collar 16 guides the rotational trajectory of the traveler 15 .

The two traditional twisting devices described above, the double twisting machine and the ring spinning frame, are ingenious as shown in Figure 1, but the defects are also obvious, that is, both require two different processes, as mentioned above. The double twisting machine needs two processes of doubling and twisting, while the ring spinning frame requires spinning and winding processes. Different processes mean different sites, production equipment and energy consumption in both places. In place to directly generate the final twisted multi-ply bobbin from a single yarn, or to realize the one-step process from roving to the final finished package, it can save half of the space and power, which can greatly improve the economic benefits.

SUMMARY OF THE INVENTION

In order to solve the defects of the traditional twisting equipment including the double twisting machine and the ring spinning frame pointed out in the above background art, the present invention provides a twisting device and a twisting machine using the twisting device that can The two processes required by the traditional double twisting machine and the ring spinning frame are combined into one, and the finished twisted multi-strand bobbins or bobbins can be produced directly from the multi-cone single-strand yarn or roving in one go, thereby saving a lot of money.

The yarn winder can be continuously rotated, and the rotation direction of the yarn winder and the rotary twister is the same, but there is a difference in the rotational angular speed of the two to ensure that the yarn winder can The yarn is drawn from the rotary twister and wound on the winder or ensures that the rotary twister can draw the yarn from itself and wind it on the winder .

When the multi-ply yarn input to the twisting device passes through the main twister, the twisting operation is performed as described above and wound on the yarn winder. Next, in the present invention, the winding The strands wound on the winder will be unwound from the winder to leave the main twister, and the strands leaving the main twister can be directly pulled and collected. It is wound into a twisted multi-strand bobbin, for example, as shown in the sub-diagram (A) of Figure 1. In this case, the power for the multi-strand yarn to be unwound from the yarn winder comes directly from the twisting. The pulling force of the collection winding device of the subsequent multi-strands; of course, in the present invention, the multi-strands leaving the main twister can even be pulled into additional subsequent twisters in addition to the main twister. The twister performs the second or more subsequent twisting operations.

The present invention preferably adopts a further optimized technical solution that a differential transmission device is used between the rotary twister and the yarn winder to enable the two to rotate together in the same direction and to ensure that there is a difference in rotational angular speed between the two.

On the basis of the above-mentioned preferred embodiment using a differential transmission device, preferably, the yarn winder of the present invention will be located outside the rotary twister, and the multi-strand twisted by the rotary twister The thread is wound on the winder from outside the yarn winding portion of the winder, while the differential transmission is located inside the rotary twister.

As a preferred further embodiment, the rotary twister includes a hollow shaft that is mounted on the support and can be driven to rotate freely, and the rotary twister further includes a shaft that is connected to the shaft. A hollow drum that is fastened as a whole, the multi-strand wires fed into the rotary twister pass through the hollow interior of the rotary shaft, and will bend and pass through the rotary shaft and then enter the guide on the drum wall of the rotary drum. Yarn passage; the multi-strand threads are wound on the yarn winder after passing through the yarn guiding passage. As mentioned above, the multi-stranded wire fed into the twisting device of the present invention will be subject to axial pulling force everywhere, so the multi-stranded wire fed into the rotating shaft can be bent and combined with the rotation of the rotating shaft. The ring spinning frame can achieve the twisting effect of one turn and single twist on the multi-strand yarn, the hollow drum can accommodate the differential transmission device, and the multi-strand yarn enters the drum of the drum whose size is enlarged from the rotating shaft. The back of the wall facilitates winding onto the subsequent winder from outside the winder. The yarn winder comprises a central shaft located on the axis of rotation thereof, and also comprises a yarn winding drum freely rotatable around the central axis, and a multi-strand thread passing through the yarn guiding passage of the rotary drum is provided. It will be wound on the spool, which is actually the core component of the spooler, and the multiple strands wound on the spool will leave the main twister.

As a further preferred implementation solution in the implementation of the above-mentioned specific embodiment, in the present invention, the hollow shaft has a hollow channel axially penetrating the entire shaft in the direction of the axis of rotation of the shaft, and the hollow shaft is fed into the shaft. The multiple strands of the twisting device will first pass through the hollow channel; a yarn guide block is fastened and inserted into the shaft body of the rotating shaft, and the yarn guide block has a channel for the multiple strands to pass through, and the channel The opening of one end is butted with the hollow channel of the rotating shaft, and the opening of the other end is butted with the yarn guide channel of the drum, and the multiple strands fed into the twisting device are folded in the channel of the yarn guide block. After bending, it is output from the opening at the other end of the channel to the outside of the rotating shaft and enters the yarn guiding channel of the rotating drum, that is, the multiple strands fed into the main twister will be in the yarn guide block of the rotating shaft. At least one bend has occurred inside.

On the basis of the above-mentioned preferred implementation scheme, as a preferred embodiment of the differential transmission device, in the present invention, the position of the central shaft located outside the winding drum is fastened and installed with a magnetic The central shaft fixing piece that does not rotate with the bobbin; the rotating shaft is fastened with a driving gear that can drive the differential transmission, and the driving gear is coaxial with the rotating shaft and will follow the rotating shaft. The rotating shaft rotates together; the differential transmission device includes a first transmission gear that meshes with a drive gear extending into the rotating drum, and the differential transmission device also includes a coaxial fastening with the first transmission gear The second transmission gear is an integral body, and the differential transmission device further includes a gear mounting plate for installing the first transmission gear and the second transmission gear, and the gear mounting plate is fastened on the center shaft. ; The yarn winder also includes a driven gear that is fastened as a whole with the yarn winding spool, the rotational axis of the driven gear coincides with the rotational axis of the winder, and the receiving The movable gear meshes with the second transmission gear. In this way, the driving gear integrated with the rotating shaft is transmitted to the driven gear integrated with the winding spool through the speed change of the two transmission gears. Rotational angular velocity difference in direction rotation.

Although the multi-stranded yarn unwound from the bobbin similar to the bobbin of the ring spinning frame can be directly continuously drawn and wound into the twisted multi-stranded bobbin, in order to make full use of the yarn from the winding In the present invention, as an optimization measure of the foregoing embodiment, the twisting device provided by the present invention may further include a pair of The multiple strands leaving the primary twister are again subjected to the secondary twister of the twisting operation. The secondary twister may clamp the multi-strands fed therein and rotate the multi-strands to twist the multi-strands. In this way, it is possible to make full use of the natural rotation process of the multi-stranded wire unwound from the yarn winder of the main twister, because one end of a section of multi-stranded wire can be twisted by clamping it at one end and then rotating it. Therefore, the present invention Optionally, active clamping and rotation of the strands leaving the primary twister can be performed to perform a secondary twist. In the present invention, the name of the secondary twister is derived from the fact that the secondary twister can perform the secondary twisting operation on the multiple strands leaving the main twister. In fact, the secondary twister can also The "secondary twister" is called the primary twister, or the primary twister is called the "primary twister" and the secondary twister is called the "secondary twister" ".

For a twisting device provided by the present invention, it is bound to be combined with a winding input device for parallel multi-stranded wires and a collection and winding device for twisted multi-stranded wires in practical applications. Referring to the schematic diagram of FIG. 1 , The collecting and winding device for twisting the multi-stranded wire is bound to continuously pull the multi-stranded wire output from the twisting device, that is, it will continue to pull the multi-stranded wire output from the secondary twister. As long as the continuously drawn multi-strand wire is bent, it will produce a clamping effect on the multi-strand wire at the bend, so it is a further optimization of the above-mentioned optimization technical measures for adding a second twister. According to the present invention, the secondary twister can produce a clamping effect on the multi-strand wires by bending the multi-strand wires fed into it. Tightening the strands also rotates them to impart a secondary twist to the strands fed into them. In this way, the present invention can ensure the effect of twisting the multiple strands through the two superimposed twisting of the main twister and the secondary twister.

As a specific embodiment of the above-mentioned secondary twister that clamps multiple strands by bending and rotates the multiple strands to implement secondary twisting, the secondary twister has a The multiple strands of the primary twister are fed into the straight passage through which the multiple strands of the secondary twister pass, and the secondary twister further includes a rotating member that can continuously rotate around the straight passage ; The multi-strands fed into the second twister will produce "N"-shaped two bends, that is, the first bends deviate from the direction of the straight passage into the rotating part, and then the rotating part is bent again. Output after upper bending. The multiple strands fed into the twisting device will deviate from the straight passage and be bent backward into the rotating member, and then be bent forward and output on the rotating member; the backward bending refers to the It is the bending of the multi-strand wire towards the rear of the direction of travel of the multi-strand wire in the straight channel; the forward bending refers to the direction of travel of the multi-strand wire after being bent on the rotating member and the direction of the multi-strand wire. The lines travel in the same direction within the straight channel. Specifically, the secondary twister includes a hollow wire tube through which the multi-strand wires are fed, and the hollow part of the wire tube constitutes the straight passage; the rotating member is the wire tube A twisting disc of the outer jacket, the twisting disc can continuously rotate around the wire tube; the multi-strand wires fed into the second twister are bent backward at the part passing out of the wire tube and are The twisting disc is bent forward and then output. In this embodiment, the "N"-shaped two bends are used to ensure the clamping effect on the multi-strand wires, that is, two bends are used to ensure that the multi-strand wires are added with the rotating member. The twisting discs are rotated together and unwound from the main twister's winder and are clamped very securely, thus ensuring that the secondary twist can be reliably applied to the multiple strands. Of course, the implementation of the secondary twister of the present invention can never be limited to this implementation. For example, even if only one small-angle obtuse-angle bending is used, for example, the method of clamping with a rubber pinch roller can be very good. It is also possible to apply clamping to the strands, or to use a three-pass or even more bending mechanism with more sharp-angle bends than the "N" type.

Finally, the present invention also provides a twisting machine, the twisting machine uses the aforementioned twisting device, and the twisting machine using the twisting device as mentioned above can conveniently combine the yarn doubling process with the twisting process. The process is integrated, or the two processes of twisting and winding are integrated, only need to be equipped with a winding device that feeds the multi-strand wire to the twisting device and continuously draws the twisted post-twisting device from the twisting device. A collection and winding device that collects and winds the multi-strand threads into twisted multi-strand bobbins or yarn bobbins.

To sum up, the twisting device and the twisting machine provided by the present invention can be said to perfectly inherit the twisting principle of the mature double twisting machine and the ring spinning frame, and combine the two into one, and can It is convenient to integrate the two processes necessary for the traditional double twisting machine and the ring spinning frame into one twisting machine and complete it in one go, and successfully use a single twisting machine to realize the traditional double twisting in one step. The production target of the two separate processes of the spinning frame and the ring spinning frame saves space, power consumption and corresponding labor costs.

This figure also shows a series of complete production process flow from the doubling of single strands to the winding and collection of twisted multi-strand strands on the basis of FIG. The entire production process flow of the twisting machine with a twisting device, it can be seen from this figure that the twisting machine using the twisting device provided by the present invention can combine the traditional double twister and the ring spindle as described above. The two processes of the spinning frame are combined into one process and completed on a single twisting machine, only need to be equipped with the spool ring 14 for doubling as shown in the lower part of the figure and the input for multi-strand or roving. The multi-strand wire winding input device represented by a pair of winding rollers 12 and the collecting and winding device represented by the winding rollers 12 and the transverse guide are shown in the upper part of the figure to draw, collect and twist the multi-strand wires. The supporting devices such as the yarn device 13 can directly produce the final product of twisted multi-strand bobbins 6 from multiple single-strand bobbins 1 in one step, or directly produce spun yarn bobbins from one roving bobbin. When the transmission belt with the reference number 10 in the figure slides in the direction of the black solid arrow against the friction transmission wheel 1802 fastened below the rotating shaft 18, the rotating shaft 18 and even the rotating drum 1901 and the rotating plate fastened together with it. 1904, the turntable fixing frame 1905, and even the driving gear 1803 and the yarn guide block 1801 fastened to the rotating shaft 18 will be driven to rotate continuously in the clockwise direction indicated by the arc-shaped arrow, and the yarn winder 20 includes its The core component bobbin 2001 will also continue to rotate in the clockwise direction indicated by the arc-shaped arrow under the driving of the conventional differential device 22 . Of course, if the traveling direction of the transmission belt 10 in FIG. 4 is changed to the opposite direction, the co-rotating directions of the rotary twister and the bobbin will also be reversed. Note that Fig. 4 shows the coiling effect and coiling direction of the multiple strands on the yarn winding drum 2001 when the rotational angular velocity of the drum 1901 is greater than the yarn winder 20, and in the specific implementation, the difference can also be completely passed through the difference. The high-speed transmission device makes the rotational angular velocity of the winder 20 greater than the co-rotational angular velocity of the drum 1901. As a result, the winding direction of the multi-strand yarn on the winding drum 2001 will be the same as that of the multi-strand yarn shown in FIG. 4 . The winding direction of the wire is just the opposite. During the specific implementation of the present invention, the winding direction of the multiple strands on the yarn winding drum 2001 can be adjusted and set according to the needs of the production process. After the direction is determined, the direction in which the multiple strands are unwound from the yarn winder 20 is clockwise or counterclockwise, and everything is adjusted based on specific process parameter settings.

Fig. 5 shows a step-by-step dismantling schematic diagram of the first embodiment of the twisting device provided by the present invention. In order to save the space of the document page occupied by the accompanying drawings, Fig. 5 is placed horizontally, so please observe the reference signs. View Figure 5 from an angle. The left side of the figure shows the effect diagram when the twisting device of this embodiment is disassembled into several main core components, and the effect diagram of the further disassembly of each core component is indicated by the arc arrow The figure in the circle enclosed by the dotted line is shown. The upper right corner of the figure also shows the technical characteristics of the rotating shaft 18 and the yarn guide block 1801 fastened and inserted thereon in the form of a perspective view. The blank area in the figure is enlarged to show some technical features of the central shaft fixing member 2102 and the magnetic attraction ring 2103 matched with the central shaft fixing member 2102 for fixing the central shaft 21 by using space magnetic force.

FIG. 6 is a schematic diagram of a second embodiment of a twisting device provided by the present invention. In contrast to the first embodiment shown in FIGS. 3 , 4 and 5 , the twisting device of the second embodiment has a secondary twister 23 located in the upper area of FIG. 6 in addition to the main twister. The second embodiment The main twister of the first embodiment is exactly the same as the main twister of the first embodiment except that a pinch roller 2004 of elastic material which is close to the outside of the winding drum 2001 is added outside the yarn winder 20 . As shown in FIG. 6 , without loss of generality, the pressure roller 2004 can preferably be made of a relatively soft rubber material, and the pressure roller 2004 will be driven to rotate together with the rotation of the winding drum 2001 , except for the difference between the two. In addition to the rolling friction, there is the mutual pressing force, and this pressing force can be used to make the multiple strands relatively firmly adhere to the surface of the bobbin 2001 so as not to slip easily. It can also be seen from the figure that the pressure roller 2004 is mounted on a frame-type pressure roller bracket 200402, and the pressure roller bracket 200402 is hinged on a pressure roller support rod 200404, and the pressure roller supports In the second embodiment, the rod 200404, like the bracket 1804 for installing the main twister and the magnetic attraction ring 2103 for fixing the central shaft 21 of the main twister, are fixed to the twisting machine for installing the twisting device provided in the second embodiment. on the rack. In the second embodiment, as shown in FIG. 6 , the pinch roller 2004 made of elastic material is pulled by an elastic band 200403 through the pinch wheel bracket 200402 and is tightly wound around the yarn winder 20 Above the spool 2001 of the multi-strand yarns rotated and twisted by the main twister, and the pinch roller 2004 is located above the drum 1901 so as not to hinder the multi-strand yarns drawn from the drum 1901 It is wound on the yarn winder 20. Like the first embodiment shown in Figures 3, 4 and 5, the yarn winding bobbin 2001 of the main twister in the second embodiment also presents a contour with a certain slope. The truncated truncated shape of the bobbin 2001 is optimized to the truncated truncated shape whose outer contour diameter gradually decreases from bottom to top, which not only facilitates the unwinding of the multiple strands from the bobbin winder 20, but also facilitates the unwinding of the yarn from the drum 1901. The multiple strands drawn and wound on the yarn winding drum 2001 move upward to avoid accumulation at the bottom of the yarn winding drum 2001, which will slow down the traveling speed of the multiple strands and cause the uneven twisting degree of the multiple strands; The introduction of the wheel 2004 is to ensure that the multiple strands coiled on the winding drum 2001 will not slip on the outer surface of the yarn winding drum 2001. Note that the upper and lower ends of the pressing wheel 2004 in the second embodiment are shown in FIG. 6 . All have a chamfered structure, the bottom chamfered structure can try not to hinder the multiple strands from sliding to the top of the winding drum 2001, and the upper chamfered structure can avoid being pulled and unwound away from the main twisting as much as possible. Therefore, the introduction of the pressure roller 2004 that is close to the yarn winder during the implementation of the present invention can realize at least three functions as described above. Note that this pressure roller can also be used in the first embodiment and other aspects of the present invention. possible implementations. In order to save space to show the core twisting device, Fig. 6 and Fig. 3 omit the multi-stranded wire input device for feeding the multi-stranded wire into the twisting device and the drawing to collect the multi-stranded wire output from the twisting device and coil it. A multi-strand wire collecting and winding device wound into a twisted multi-strand bobbin, but comparing FIG. 5, it is completely conceivable that the use effect of the second embodiment is similar to that of the first embodiment applied to a twisting machine. In order to highlight the two core twisting components of the twisting device, Fig. 6 omits to show the multi-stranded wire, but referring to Figs. the direction in the twister 23. As shown in FIG. 6 and referring to FIG. 4 , in the second embodiment, the multi-stranded wire is also unwound from the bobbin 2001 under the continuous pulling of the multi-stranded wire collecting and winding device of the twisting machine and passed through the middle. The entire circle of transparent gaps between the shaft 2102 and the magnetic attraction ring 2103 continues to move forward, as shown in FIG. 6 and with reference to FIG. The yarn guide tube 2302 of the secondary twister 23 enters the secondary twister 23, and after the secondary rotation and twisting of the secondary twister 23, as shown in FIG. The final product wound into a large roll is twisted with multiple bobbins 6 . As shown in FIG. 6 , the lower main twister and the upper secondary twister in the second embodiment are driven to rotate by two transmission belts 10 respectively. Note that for the present invention, the two transmission belts are under different process conditions. The transmission direction of 10 can be the same or different, and please note that the installation positions of the main twister and the secondary twister in the specific embodiment of the present invention are not limited to the up and down orientation shown in FIG. 6 . Figure 3, Figure 5, and Figure 6 all show important components in the primary twister and the secondary twister in gray shading.

FIG. 7 is a schematic cross-sectional view of the secondary twister of the second embodiment passing through its axis. Referring to FIG. 6 , in addition to showing the cross-sectional schematic diagram of the secondary twister 23 , this figure also shows how the twisted multi-stranded wire 5 leaving the primary twister passes through the secondary twister 23 of. As shown in FIG. 7 and referring to FIGS. 6 and 4 , the twisted multi-stranded wire 5 drawn and unwound from the spool 2001 of the primary twister first enters a hollow wire of the secondary twister 23 In the tube 2302, as shown in FIG. 7, the axially transparent hollow part of the wire tube 2302 constitutes a straight passage of the twisted multi-stranded wire 5, and the outer part of the wire tube 2302 is sheathed with a hollow main shaft. 2303, the lower part of the main shaft 2303 has the structure of a friction transmission wheel 2305 protruding outward, and the upper part of the main shaft 2303 is fastened with a hollow twisting turntable 2301, and the twisting turntable 2301 is also the aforementioned two A specific embodiment of the rotating part of the twister. Referring to FIG. 7 , the lower part of the wire tube 2302 of the secondary twister 23 in the second embodiment is supported by a wire tube bracket 2308 and is defined in the form of a key and a keyway connection so that the main shaft 2302 cannot rotate, and is sleeved on There is a rolling bearing between the main shaft 2303 outside the conduit 2302 and the conduit 2302. Referring to FIG. 6, the friction transmission wheel 2305 can be continuously rotated under the friction of the transmission belt 10. As shown in FIG. 7, the main shaft 2303 and the two supporting the Rolling bearings are also provided between the second twister brackets 2307 of the twister 23, so that the main shaft 2303 and the rotating parts on it as shown in FIG. Driven by the drive belt 10 , the drive belt 10 continuously rotates and the direction of rotation is clockwise or counterclockwise can be switched by the traveling mode of the drive belt 10 . As shown in FIG. 7 , the twisted multi-stranded wire 5 entering the secondary twister 23 from below passes through the upper end of the threading tube 2302 and then bends back and exits through a threading hole 2304 embedded in the twisting turntable 2301 In the second twister 23, the twisted multi-stranded wire 5 passes through the threading hole 2304 and reaches the outside of the twisting turntable 2301, and then bends forward to the multi-stranded wire collecting and winding device. Knowing that the multi-stranded wire collection and winding device is the driving power source for the entire twisted multi-stranded wire 5 and even the untwisted multi-stranded wire in front of it to pass through the main twister, and also the multi-stranded wire exists everywhere in the whole process. Source of axial tension. As shown in FIG. 7 and referring to FIG. 1 and in combination with the previous analysis on the radial clamping force generated by the bending of the multi-strand wire, the twisted multi-strand wire 5 is bent in the secondary twister and will generate For its radial clamping effect, when the twisted multi-strand wire 5 rotates with the rotating member, referring to the sub-figures (C), (D) and (E) of FIG. 1, the rotating member is located as the second embodiment. A section of multi-strand wire between the twisting turntable 2301 and the clamping place of a pair of winding rollers 12 of the multi-strand wire collecting and winding device will be twisted, which is equivalent to clamping one end of a section of multi-strand wire. When it is not tightened, the other end is also clamped and unwound from the spool 2001, and the multi-strand yarn will be twisted to form an effective twist. Note that in order to highlight the twisting effect produced by the clamping and rotation of the multi-stranded wire by the secondary twister 23, the twisted multi-stranded wire 5 in FIG. , and before that, they were displayed with two parallel lines without twisting, in order to highlight the key points and show that the key twisting process of the second twister occurs at the clamping of the multi-strand and the subsequent collection and winding of the multi-strand between devices. Of course, the actual implementation is not like the two parallel lines deliberately shown in FIG. 5 , the twisted multi-strand lines 5 have already been twisted by the main twister before entering the secondary twister 23 . twisted in a spiral. A vertical dot-dash line in FIG. 7 refers to the rotation axis of the rotating member, that is, the rotation axis of the twisting turntable 2301 and the hollow main shaft 2302 . Finally, it should be noted that the starting point of the two-way bending embodiment of the "N" type small-angle acute angle shown in Figure 7 is to make better use of acute-angle large-angle high-strength bending and increasing the number of bends. The thread exerts a sufficient clamping force, but the embodiment of the secondary twister of the present invention is by no means limited to this, in fact only the twisted multi-strand thread 5 leaving the main twister is clamped and rotated The second twist can be implemented, as shown in FIG. 8 , or a large-angle obtuse-angle bending is adopted in order to avoid excessive axial tension of the multi-strand wires, and so on.

FIG. 8 is a schematic diagram of two other specific implementations of the secondary twister, and the left and right sides of a vertical dot-dash line in the figure are the separation lines of the two specific implementations. As shown in the figure to the left of the dividing line in Figure 8, in this somewhat similar embodiment of the secondary twister to the embodiment shown in Figure 7, there is no conduit 2302, but a hollow main shaft 2303, main shaft 2303 The friction transmission wheel 2305 matched with the transmission belt 10, the twisting turntable 2301 tightly sleeved above the main shaft 2303, and the secondary twister bracket 2307 are basically the same as the embodiment shown in FIG. 7, as shown in FIG. 8 The multiple strands fed into the secondary twister shown on the left side of the dividing line will directly penetrate into the hollow part of the main shaft 2303 and then go around a rotating shaft 2309 lying in the middle of the twisting turntable 2301 for one turn and then output. To the multi-strand wire collection and winding device of the twisting machine, as shown in the figure, the rotating shaft 2309 is equipped with a rolling bearing 2310 at the installation site of the twisting turntable 2301, so the rotating shaft 2309 basically does not hinder the multi-strand yarn direction. The collection and winding device travels. As mentioned above, since the multi-strand wire will have axial tension everywhere under the continuous pulling action of the collection and winding device, the multi-strand wire wound on the rotating shaft 2309 will be removed. The rotating shaft 2309 is stretched on the rotating shaft 2309 so as to produce a clamping effect on the multi-strand wires, and the rotating shaft 2309 will follow the main shaft 2303 and the twisting turntable 2301 as shown by the hollow arc arrow in the figure. Driven by the drive belt 10, the transmission belt 10 continuously rotates, so the twisting of the multiple strands is also performed as in the embodiment shown in FIG. 7 . This embodiment on the left side of the dividing line in Fig. 8 is different from the sharp-angled bend shown in Fig. 7, which has been analyzed before, or even any angle of bending. This embodiment uses a continuous bending method of multiple strands To achieve the clamping effect on the multi-strand wire and then cooperate with the continuous rotation to twist the multi-strand wire. For the specific twisting principle, please refer to Figure 1 and the analysis above. As shown in the embodiment on the right side of the vertical dotted dividing line in FIG. 8 , the hollow main shaft 2303 of this embodiment, the friction transmission wheel 2305 and the transmission belt 10 thereon, and the twisting turntable fastened on the rotating shaft 2303 2301 and the secondary twister bracket 2307, etc., are similar to the embodiment shown in FIG. 7 and the embodiment on the left side of FIG. 8, and the difference from the embodiment on the left side of FIG. The elastic material clamping roller 2311 is used to simply and directly achieve the purpose of clamping the multi-strand wire. Note that in FIG. 8, the main shaft 2303 and The rotation axis line of the twisting turntable 2301 thereon is shown on the left side of FIG. 8. In this embodiment, a pair of multi-strand thread clamping rollers 2311 made of elastic material are also equipped with rolling bearings 2310, so they will not interfere basically. The multi-strands are pulled and traveled by the collecting and winding device, and only the multi-strands leaving the secondary twister are subjected to rotational twisting. FIG. 8 and FIG. 7 illustrate the basic idea of the secondary twister of the present invention, which is to take advantage of the effect that the multiple strands leaving the main twister will naturally rotate during the process of unwinding from the winder 20. The secondary twisting is performed on the multiple strands leaving the main twister, and the secondary twisting can be realized as long as the secondary twister clamps the multiple strands in the process of rotating them. The active rotation of the multi-strand yarn also facilitates the active rotation and unwinding of the multi-strand yarn on the yarn winder 20 of the main twister. As for the method of how the secondary twister clamps the multi-strand wires, as shown in Figures 7 and 8, various methods such as the above-mentioned bending or direct clamping can be adopted. As mentioned above, whether the multi-strand yarns are wound on the yarn winder 20 is clockwise or counterclockwise, which can be switched by changing which angular velocity between the drum 19 and the yarn winder 20 is larger, and the rotation direction of the second twister As shown in FIG. 6, it can also be switched by changing the traveling direction of the transmission belt 10 matched with the secondary twister, so the present invention can design and set different process parameters according to the specific production process conditions, so as to efficiently implement the multi-strand wire twist.

Detailed ways

The content of the above section of the invention will be described in detail below in conjunction with the content of the foregoing two sections "Background Art" and "Description of Drawings". Note that when citing any drawing in the specification, the previous section on the description of the drawings is implicitly quoted. related content.

Specifically, with reference to all the drawings except FIG. 2 and the analysis of the foregoing background art and the description of the drawings, the first and second embodiments of a twisting device provided by the present invention and the one shown in FIG. 8 The other two embodiments of the second embodiment, and even all possible embodiments based on the present inventive concept, can perform twisting operations on the multi-strands fed into them, as with the other prior art solutions disclosed so far. As shown in FIGS. 3 , 4 , and 6 to 8 , the twisting device includes a main twister for twisting the multiple strands and a bracket 1804 for installing the main twister. Compared with other technical solutions, as shown in FIGS. 3 to 6 , the twisting device provided by the present invention is characterized firstly in that the main twister includes a multi-strand wire that can be fed into the twisting device to fold. A rotary twister 19 that bends and rotates to twist the multiple strands, the main twister also includes a yarn winder 20, and the multiple strands fed into the twisting device are twisted by the main twister After twisting, the rotary twister 19 of the device will be wound on the yarn winder 20; , and the rotation directions of the winder 20 and the rotary twister 19 are the same, but there is a difference in the rotational angular speed of the two, so as to ensure that the winder 20 can draw the multiple strands from the rotary twister 19 out and wind on the winder 20 or ensure that the rotary twister 19 can draw the strands out of itself and wind on the winder 19 . Specifically, referring to FIG. 4 , for the present invention, when the rotational speed of the winder 20 is greater than the rotational speed of the rotary twister 19, the winder 20 is used for pulling the multiple strands. The power source pulls the strands from the rotary twister 19 and winds them on the winder 20 itself, and when the rotational speed of the rotary twister 19 is greater than the rotational speed of the winder 20 At this time, the rotary twister 19 is used as a power source for winding the multiple strands onto the yarn winder 20 and pulling the multiple strands out of the rotary twister 19 itself. As described in the analysis of the twisting principle of the double twister and ring spinning in the previous section of Background Art, in the present invention, the multi-strand yarns are bent and rotated in the rotary twister 19 of the main twister, so that the untreated The multiple strands entering the twisting device are subjected to the twisting operation, because either the yarn winder 20 or the rotary twister 19 is used as the power to wind the multiple yarns on the yarn winder 20 The source, the multi-strands entering the rotary twister 19 will be subjected to a continuous pulling force so that they will be subjected to radial clamping force at their bends, just like pinching one end of the multi-strand by hand for a continuous period of time. Rotating will make the section between the output end of the multi-strand wire and the other end pinched by hand will be twisted, the rotary twister 19 in the present invention is equivalent to pinching the multi-strand wire described here. the hand that continuously rotates. Referring to Fig. 4, for the first embodiment, when the rotary twister 19 of its main twister rotates along the clockwise dimension indicated by the arcuate arrow in Fig. 4, the angular velocity is higher than the angular velocity of the winding yarn that rotates in the same direction therewith If the angular velocity of the winder 20 is slightly lower, the winder 20 will draw the multiple strands from the rotary twister 19 and wind it on itself; and if the rotational angular velocity of the winder 20 is less than the If the rotational angular velocity of the rotary twister 19 is in the same direction, the multi-stranded wire can also be wound on the yarn winder 20. In that case, the multi-stranded wire will be driven by the rotary twister 19 as shown in FIG. 4 . is wound on the winder 20. When specifically operating the first embodiment, it is only necessary to wind the multi-strand yarn on the yarn winder 20 for a plurality of times during the production initialization stage of the twisting device and the twisting machine equipped with the twisting device to make it close to the The yarn winder 20 does not slip easily, so that the initial tightening friction force required for winding the multiple strands on the yarn winder 20 can be obtained. In addition, as shown in Fig. 3 to Fig. 5, the outer wall of the spool 2001 of the yarn winding part of the yarn winder 20 of the first embodiment is not vertical but has a certain upward inclination to facilitate winding on the yarn winder The multi-strand coils on 20 automatically slide upward to facilitate subsequent unwinding, and maintain the uniformity of the linear speed at which the multi-strands are wound on the yarn winder 20. Of course, even if the multi-strand coils are stacked together and formed As long as the subsequent pulling force is large enough for multiple layers, it is also possible to ensure that the multiple strands are unwound from the yarn winder 20 . Referring to Fig. 4, the multi-strand wire output from the twisting device provided by the present invention will be drawn and output to the multi-strand wire collecting and winding device represented by the upper pair of winding rollers 12 in Fig. 4, and then guided in the transverse direction. With the cooperation of the yarn device 13, the yarn is regularly wound around the final twisted multi-strand bobbin 6. As shown in FIG. 4 , in the first embodiment, the bend of the multi-strand wire in the main twister is at the passage 180101 of the yarn guide block 1801 in the rotating shaft 18 indicated by the reference numeral 180101, and the following is as before. As described and shown in FIG. 4 , due to the difference in the rotational angular velocity between the yarn winder 20 and the rotary twister 19 , the multiple strands can be drawn from the rotary twister 19 and wound on the yarn winder 20 .

As shown in Fig. 3 and Fig. 4, when the multi-stranded yarn input to the twisting device passes through the main twister, the twisting operation is performed as described above and wound on the yarn winder 20, Next, referring to Figures 4 and 6, in the present invention, the multiple strands wound on the yarn winder 20 will be unwound from the yarn winder 20 to leave the main twister, As shown in FIG. 4, the multi-strands leaving the main twister can be directly drawn, collected and wound into twisted multi-strand spools, for example, as shown in the sub-figure (A) of FIG. 1, in this case The power for the lower multi-stranded wire to be unwound from the yarn winder 20 is directly derived from the pulling force of the collecting and winding device for the twisted multi-stranded wire; of course, in the present invention, as shown in FIG. 6 The strands leaving the main twister may even be drawn into additional subsequent twisters in addition to the main twister for a second or more subsequent twisting operations.

Referring to Fig. 1 and Fig. 2 and in conjunction with the analysis in the Background Art section, in the present invention, the rotary twister 19 shown in Fig. 4 is actually based on the twisting principle of the ring spinning frame to feed the many The strands are subjected to a single-turn twisting operation, because the rotary twister 19 bends and rotates the multiple strands fed into it like the aforementioned ring spinning frame, because the rotary twister 19 and its subsequent There is a difference in the rotational speed between the two winders 20, and in combination with the actual use of the main twister, during initialization, the multi-strand yarns will be wound on the winder 20 taut in advance to ensure that the twister 19 rotates. Both the yarn winder 20 and the yarn winder 20 can continuously draw and wind the multiple strands on the yarn winding device 20, so that the multiple yarns fed to the main twister of the twisting device of the present invention are continuously drawn. Tensile force, there will be axial pulling force everywhere on the multi-strand wire, so the bending of the multi-strand wire in the rotary twister 19 will produce a clamping effect on the bend of the multi-strand wire. Referring to sub-figures (D) and (E) of FIG. 1 , the continuous rotation of the twister 19 with the rotation of the main twister is like pinching the bends of the multi-strand wires around the multi-strands as previously described. As long as the yarn outlet continues to rotate, the rotary twister 19 will apply twist to the multi-strand yarn, and the pair of winding rollers 12 in the (d) sub-figure and (e) sub-figure in FIG. 1 is also equivalent to the one described here. The multi-strand output port. Next, due to the difference in the rotational angular velocity between the winder 20 and the rotary twister 19 , the multiple strands can be drawn from the rotary twister 19 and wound on the winder 20 . Referring to FIG. 1 , the winder 20 in the main twister of the present invention is actually equivalent to the bobbin 17 in the ring spinning frame. For the present invention, as shown in FIG. The twisted strands on the winder 20 can be directly drawn and collected and wound into twisted bobbins, which eliminates the need to wind up multiple bobbins required by conventional ring spinning processes The winding process in which the wound twisted stranded wire is connected end to end and wound into a large coil of twisted stranded bobbin or spun yarn spool is the final product. The reason why the yarn winder 20, a device similar to the bobbin of the ring spinning frame, is used in the main twister of the present invention is to ensure the uniformity of the twisting of the multiple strands as much as possible. Referring to Figures 1 and 4, because if the yarn winder 20 is directly used as a collection and winding device for the final product packaged yarn wound into a large volume, with the continuous winding and accumulation of multiple strands on the yarn winder 20, it is quite The outer diameter of the yarn winder 20 will increase, so that the linear speed at which the multiple strands are wound and collected on the yarn winder 20 will be changed, thereby affecting the uniformity of the twisting of the multiple strands. In the present invention, the yarn winder 20, which is similar to the bobbin of the ring spinning frame, can actually be arranged so that the twisting device of the present invention can perform a subsequent second second on the multiple strands leaving the main twister. The twisting operation provides a multi-strand swivel output.

In order to precisely control the speed difference between the rotary twister and the yarn winder while saving costs and avoiding the use of expensive servo motors or stepper motors, referring to FIG. 3 to FIG. A differential transmission device 22 is used between the twister 19 and the winder 20 to enable them to rotate together in the same direction and to ensure that there is a difference in rotational angular speed between the two, which is a further optimized technical solution. Differential transmission is already a very mature and practical technology in the field of machinery. For example, the corresponding transmission ratio can be achieved by changing the gear ratio of two gears that mesh together. For the present invention, to achieve rotational twisting The differential effect of the two co-rotating components of the winder 19 and the winder 20 can be constructed by a spur gear or a bevel gear transmission mechanism, so that it is only necessary to simply drive one of the two to rotate. The rotating device can drive another component to rotate in the same direction with differential speed.

On the basis of the above-mentioned preferred embodiment using a differential transmission, preferably, as shown in FIGS. 3 to 5 , the yarn winder 20 of the present invention is located outside the rotary twister 19 and passes through the rotary twister 19 The twisted multiple yarns are wound on the yarn winder 20 from the outside of the yarn winding portion of the yarn winder 20 , and the differential transmission 22 is located inside the rotary twister 19 . As shown in FIG. 3 to FIG. 5 , implementing the rotary twister 19 and the yarn winder 20 as separate components is beneficial to the convenience of manufacturing and maintenance during the implementation of the present invention; It is also logical and beneficial to realize that the multiple wires from the rotary twister 19 are wound on the yarn winder 20; considering that the differential transmission device needs to avoid the adverse effects of dust and moisture on the precise variable speed transmission as much as possible, The differential transmission device should be equipped with isolation protection measures such as dustproof and waterproof, so it is a very good choice to deploy the differential transmission device 22 inside the rotary twister 19 and the yarn winder 20. The device 22 will directly connect the two to facilitate the realization of variable speed transmission, and secondly, the two are used as a natural protective barrier to isolate it from external dust, dust, water vapor, and the like. Since the yarn winder 20 is preferably wound thereon from the outside, the size of the rotary twister 19 is bound to be larger than that of the yarn winder 20, so the differential transmission device 22 is preferably placed in the rotary twister 19 within. Of course, the differential transmission device 22 may also be located inside the winder or even outside both of them. All the preferred technical solutions are to reduce the manufacturing and operation and maintenance costs of the factory as much as possible on the basis of ensuring the effect of the differential transmission. .

As a preferred embodiment, as shown in FIG. 3 to FIG. 6 , the rotary twister 19 includes a hollow shaft 18 which is mounted on the bracket 1804 and can be driven to rotate freely. The twister 19 also includes a hollow drum 1901 that is fastened to the rotating shaft 18 as a whole. The multiple wires fed into the rotating twister 19 will be bent and passed through the rotating shaft 18 after passing through the hollow interior of the rotating shaft 18. Then enter the yarn guide channel 1903 on the drum wall of the drum 1901; In the first embodiment, the yarn guiding channel 1903 is composed of a transverse channel 190302 and a vertical channel 190301 located at the bottom of the drum 1901 as shown in FIG. 3 and FIG. 4 . In this embodiment, the yarn guiding channel 1903 is a It is formed by drilling holes on the bottom and the wall of the rotating drum 1901 , and of course, it can also be produced by welding a bent pipe to the rotating drum 1901 , or it can be realized in other ways. As mentioned above, the multiple strands fed into the rotating shaft 18 can be twisted with one turn and single twist like a ring spinning frame after one bend and combined with the rotation of the rotating shaft 18, such as As shown in FIG. 3, FIG. 4 and FIG. 5, in this embodiment, the bending of the multi-strand wires in the rotating shaft 18 is realized through a channel 180101 of a yarn guide block 1801 fastened to the shaft body of the rotating shaft 18, The interior of the hollow rotating drum 1901 can accommodate the differential transmission 22 as shown in Figs. 3, 4 and 5. After the multi-strand wires enter the cylindrical wall of the expanded rotating drum 1901 from the rotating shaft 18, they can be easily removed from the rotating drum 1901. The outer portion of the subsequent winder 20 is wound on said winder 20 . Referring to FIGS. 3 to 6 , the yarn winder 20 includes a central shaft 21 located on its rotational axis, and also includes a yarn winding drum 2001 that can freely rotate around the central axis 21. The multi-strand threads passing through the yarn guide channel 1903 of the 1901 will be wound on the yarn winding drum 2001, which is actually the core component of the yarn winding device 20, as shown in Figure 4 and Figure 6. The multiple strands on the bobbin 2001 will leave the main twister after being unwound.

As shown in FIGS. 3 to 6 , as a further preferred implementation solution when the above-mentioned specific embodiment is implemented, a hollow channel 1808 axially penetrates the entire rotating shaft 18 is provided in the direction of the rotation axis of the rotating shaft 18 . The multi-strand threads entering the twisting device will first pass through the hollow channel 1808; as shown in Figures 3 to 5, a yarn guide block 1801 is fastened and inserted into the shaft body of the rotating shaft 18, and the yarn guide block 1801 has a A channel 180101 for the multi-strand threads to pass through, one end of the channel 180101 is open to butt with the hollow channel 1808 of the rotating shaft 18, and the other end of the channel is open to butt with the yarn guide channel 1903 of the drum 1901 to feed the The multiple strands of the twisting device are bent and traveled in the channel 180101 of the yarn guide block 1801 and then output from the opening at the other end of the channel 180101 to the outside of the rotating shaft 18 into the yarn guide channel 1903 of the drum 1901, that is, feeding into the The multiple strands of the main twister will be bent at least once in the yarn guide block 1801 of the rotating shaft 18. In fact, as shown in FIG. A bend occurs when the yarn guide block 1801 is formed. As shown in FIG. 3 and FIG. 4 , in the first embodiment, after the multi-strand wires are output from the rotating shaft 18, they first enter a transverse channel 190302 drilled at the bottom of the rotating drum 1901, and then bend upward and enter the drum wall of the rotating drum 1901. In the vertical channel 190301 of the upper-drilled yarn guide channel 1903, the uppermost opening of the vertical channel 190301 leaves the drum 1901 and the rotary twister 19 at last. Using the independent and detachable yarn guide block 1801 to realize the bending of the multi-strand wire has the advantage of being convenient for disassembly, maintenance and replacement. Of course, this implementation scheme is only a preferred specific embodiment of the present invention. Others such as using conventional It is also feasible to insert a bent tube into the rotating shaft 18 to pass through the multi-strand wire and bend it, etc., and it is also based on the present invention to bend the multi-strand wire and then implement the rotation and twisting. conceived.

On the basis of the foregoing preferred implementation scheme, as a preferred embodiment of the differential transmission 22, as shown in Figs. The central axis fixing member 2102 that is separated from the magnetic force so that it does not rotate with the yarn spool; as shown in FIG. 3 to FIG. There is a magnet 2104 inlaid, and the central axis fixing member 2102 can be made of non-magnetic materials such as aluminum-magnesium alloy. The central axis fastener 2102 is matched with a hollow magnetic attraction ring 2103. The inner ring of the magnetic attraction ring 2103 A magnet 2104 that attracts the corresponding magnet on the central axis fastener 2102 is fastened and embedded on the wall. The reason why the central shaft fixing member with spaced magnetic force is used is as mentioned above in order not to hinder the free rotation of the multi-strand wires that are unwound from the yarn winder 20 and output from the main twister. This is because as shown in Figure 3 And as shown in FIG. 4, in the first embodiment, the central axis 21 is located on the rotation axis of the yarn winder 20, and the multi-strand yarn coiled on the core component of the yarn winder 20 will naturally be unwound when the yarn bobbin 2001 is unwound. Rotating around the rotating shaft 21 , if the central shaft fixing member 2102 does not use a space magnetic force to fix the central shaft 21 , the multi-strand wires will interfere with the central shaft fixing member during unwinding. As shown in FIG. 4 , in the first embodiment, after unwinding from the yarn winder 20, the multiple strands will pass through a whole circle of gaps between the central shaft fixing member 2102 and the magnetic attraction ring 2013 and pass through a hub The ring 14 comes to a pair of winding rollers 12 which make up the multi-strand collecting winding device. Note that neither the complete magnetic attraction ring 3103 nor the bracket 1804 of the twisting device is shown in Figs. 3 and 4. In reality, these two components will be fastened when a twisting device provided by the present invention is used. On the frame of the twisting machine, in order to save the space of the description and drawings and fully display the technical features that reflect the core content of the present invention, the redundant parts of the magnetic attraction ring 2103 and the bracket 1804 are removed with double wavy dotted lines and omitted. Display of a whole twisting machine using the twisting device provided by the present invention. In addition, in the first embodiment, as shown in FIG. 3 to FIG. 5 , in order to reduce the friction between the spool 2001 and the central shaft 21 that are continuously rotating, and to reduce the spool 2001 and the drum The friction between the hollow top cover 1902 of the 1901, in the first embodiment, as shown in Figures 3 to 5, the upper and lower ends of the yarn winding drum 2001 are blocked to prevent dust, dust and fine yarns The top cover 2002 and the bottom cover 2003 of the incoming bobbin 2001 are equipped with rolling bearings 2105; similarly, in order to reduce the frictional force generated by the core part of the rotary twister 19, which is the driving shaft 18, in the first In one embodiment, as shown in FIG. 3 and FIG. 4, a rolling bearing 1805 is also fitted between the rotating shaft 18 and the bracket 1804. In fact, for the first embodiment, the axial support force of the rolling bearing 1805 can be used to provide rotation and twisting. The main twister including the winder 19 and the winder 20 and even the entire twisting device provide vertical support. As shown in FIG. 4 and with reference to FIGS. 3 and 5 , the rotating shaft 18 of the first embodiment installed on the twisting machine has a friction transmission wheel 1802 fastened thereon under the rotating shaft 18 , and the use of the twisting machine of the first embodiment will provide A transmission belt 10 that is in close contact with the friction transmission wheel 1802 and continuously travels in one direction, so that the friction transmission wheel 1802 and even the entire rotating shaft 18 will also continue to rotate. The solid thick line in FIG. 4 Arrows and an arc-shaped arrow indicate the traveling and rotating directions of the drive belt 10 and the friction drive wheel, respectively, as shown in FIG. 3 , FIG. 4 and FIG. 1901, the turntable 1904, the turntable fixing frame 1905 and the yarn guide block 1801 components are all fastened together with the rotating shaft 18, so the above components of the rotary twister 19 in this embodiment will be The drive belt 10 of the twisting machine continuously rotates, and in this embodiment, as shown in the figure, it continuously rotates clockwise. In the first embodiment, in order to realize the differential transmission 22 , as shown in FIGS. 3 to 5 , the rotating shaft 18 is fastened with a driving gear 1803 capable of driving the differential transmission. The gear 1803 is coaxial with the rotating shaft 18 and will rotate together with the rotating shaft 18; the differential transmission device 22 includes a first transmission gear 2201 meshing with the driving gear 1803 extending into the rotating drum 1901, The differential transmission device 22 further includes a second transmission gear 2202 that is coaxially fastened to the first transmission gear 2201 as a whole. The differential transmission device 22 further includes a second transmission gear 2202 for installing the first transmission gear A gear mounting plate 2203 of the second transmission gear 2202, the gear mounting plate 2203 is fastened on the central shaft 21 in the first embodiment so as not to rotate with the twister 19 and the yarn winder 20 Rotate together; the yarn winder 20 also includes a driven gear 200301 that is fastened to the yarn winding drum 2001 as a whole. Referring to FIGS. 3 to 5 , the driven gear 200301 is the bottom cover 2003 of the yarn winding drum 2001. The fastening is integrated, and the bottom cover 2003 of the yarn winding drum 2001 is fastened together with the yarn winding drum 2001 . In the first embodiment, the rotation axis of the driven gear 200301 coincides with the rotation axis of the yarn winder 20 , and the driven gear 200301 meshes with the second transmission gear 2202 . In this way, the differential transmission device 22 uses the rotating action of the rotating shaft 18 to drive the winder 20 through the driving gear 1803 on the rotating shaft 18, the first and second transmission gears, and the driven gear 200301 that is fastened to the bobbin. The core component bobbin 2001 rotates together in the same direction, and only need to adjust the gear ratio of the driving gear 1803, the first and second gears and the driven gear 200301 to achieve different transmission ratios, so as to control the rotary twister 19 Which one rotates in the same direction as the winder 20 turns faster and controls whether the multi-ply yarn is wound clockwise or counterclockwise on the winder 20, and controls the rotation of the twister 19 and the winding The size of the differential between the two speeds of the 20. The reason why the central shaft 21 is fixed by the central shaft fixing member 2102 fixed by the space magnetic force so that it does not rotate together with the winding drum 2001 is because in this embodiment, the two The gear positions are all fixed indirectly by means of the central shaft 21 . Of course, the differential transmission device 22 has other implementation possibilities and there is definitely room for further improvement, such as bevel gears, friction wheels and pulleys. As shown in FIG. 3 to FIG. 5 , in this embodiment, the gear mounting plate 2203 is sleeved on the central shaft 21 by virtue of its hollow part; as shown in FIG. 5 and referring to FIGS. 3 and 4 , the first embodiment There is an axial milling and leveling structure 2107 on the central shaft 21, and the axial milling and leveling structure 2107 can be used as a spline-like structure to fasten the gear mounting plate 2203 sleeved on it so that it cannot rotate, It is only necessary that the gear mounting plate 2203 is sleeved on the hollow part of the central shaft 21 to have a structure corresponding to the axial milling structure 2107, which is a well-known technology in the mechanical field and will not be further described here. As shown in FIGS. 3 to 5 , in this embodiment, in order to improve the transmission efficiency of the differential transmission device as much as possible, a plane thrust bearing 2204 is further equipped between the second transmission gear 2202 and the gear mounting plate 2203 , between the central shaft 21 and the driving gear 2203 in the driving gear 2203 extending into the end of the rotating shaft 18 is equipped with a needle bearing 2106 to reduce friction between the two. As shown in Figures 3 to 5, the differential transmission device 22 in the first embodiment also uses three sets of transmission gears, which are evenly distributed around the rotation axis of the rotary twister 19 and the yarn winder 20. The cloth is conducive to the stability of the transmission. The hollow top cover 1902 provided for the drum 1901 in the first embodiment is mainly to protect the entire differential transmission 22 in the drum 1901 from the interference of dust, moisture and fine yarns suspended in the air in the workshop. Referring to FIGS. 3 and 4 , in this embodiment, the central shaft 21 is fixed by the central shaft fixing member 2102 so that it will not rotate with the winding bobbin 2001 because the The positions of the two transmission gears of the differential transmission 22 are indirectly fixed by the center shaft 21 through the gear mounting plate 2203 . Of course, there are other possible implementations of the differential transmission device 22 , after all, various sophisticated and practical mechanical speed change transmission devices in various industries have already emerged one after another.

Although the multi-strand yarn unwound from the bobbin 20 similar to the bobbin of the ring spinning frame can be directly continuously drawn and wound into a twisted multi-strand bobbin, in order to make full use of the yarn from the winding The multi-strands unwound from the yarn reel 20 will naturally continue to rotate with the unwinding process. In the present invention, as an optimization measure of the foregoing embodiment, as shown in the second exemplary embodiment shown in FIG. 6 . 7 and FIG. 8 , the twisting device provided by the present invention may further include a secondary twister 23 for re-twisting the multiple strands leaving the main twister. The secondary twister 23 can clamp the multiple strands fed therein and rotate the multiple strands to twist the multiple strands. That is to say, the secondary twister 23 can hold the multiple strands and actively unwind the multiple strands from the yarn winder 20 of the main twister through rotation. D) and (E) sub-figures, after one end of the multi-strand wire is clamped by a pair of winding rollers 12 or other forms, the other end of the multi-strand wire is also clamped and rotated to perform the multi-strand wire. Twisting, so that secondary twisting of the multiple strands leaving the primary twister can be performed by taking advantage of the unavoidable rotation that occurs when the multiple strands are unwound from the winder 20 of the primary twister. twist. In this way, it is possible to make full use of the natural rotation process of the multi-stranded wire unwound from the yarn winder of the main twister, because one end of a section of multi-stranded wire can be twisted by clamping it at one end and then rotating it. Therefore, the present invention Optionally, active clamping and rotation of the strands leaving the primary twister can be performed to perform a secondary twist. In the present invention, the name of the secondary twister is derived from the fact that the secondary twister can perform the secondary twisting operation on the multiple strands leaving the main twister. In fact, the secondary twister can also The "secondary twister" is called the primary twister, or the primary twister is called the "primary twister" and the secondary twister is called the "secondary twister" ". In addition, as shown in FIG. 6 , the main twister of the second embodiment is further provided with a pinch roller 2004 made of elastic material that helps to prevent the multiple strands wound on the yarn winder 20 from slipping easily. The pinch wheel 2004 In fact, it can also be applied to the first embodiment shown in Figs.

For a twisting device provided by the present invention, it is bound to be used in combination with an input device for parallel multi-stranded wires and a collection and winding device for twisted multi-stranded wires in practical applications. Referring to the schematic diagram of FIG. The collecting and winding device of the multi-strand yarn is bound to continuously pull the multi-strand yarn output from the twisting device, that is, it will continue to pull the multi-strand yarn output from the secondary twister, as described above. As long as the continuously drawn multi-strand wire is bent, it will produce a clamping effect on the multi-strand wire at the bent place, so it is a further optimized technology for the above-mentioned optimization technical measure of adding a second twister. Solution, for the present invention, the secondary twister 23 as shown in Figures 6 to 8 can produce a clamping effect on the multi-stranded wire by bending the multi-stranded wire fed into it, of course, as described above. The secondary twister 23 also rotates the multi-strand yarn while clamping it to perform secondary twisting on the multi-strand yarn fed into it. In this way, the present invention can ensure the effect of twisting the multiple strands through the two superimposed twisting of the main twister and the secondary twister. In the specific implementation, the outer diameter of the winding drum 2001 should be reduced as much as possible, so that the number of coils of the multi-stranded wire per unit length on it is as large as possible, which will be beneficial to increase the implementation of two twists on the multi-stranded wire. The number of turns twisted.

As a specific embodiment of the above-mentioned secondary twister that clamps multiple strands by bending and rotates the multiple strands to implement secondary twisting, the secondary twister is shown in FIG. 7 . 23 has a straight passage through which the multiple strands leaving the primary twister can be fed into the secondary twister 23. In this embodiment, the straight passage is the hollow of the conduit 2302. channel, the secondary twister 23 also includes a rotating member that can continuously rotate around the straight channel, in the second embodiment, the twisting turntable 2301; The multi-strand wire will produce two "N"-shaped bends, that is, firstly, it is bent away from the direction of the straight passage and enters the rotating member, and then is bent on the rotating member and then output. The multi-strands fed into the twisting device will deviate from the straight passage and bend backward into the rotating member, and then bend forward and output on the rotating member; as shown in Figure 7 and with reference to Figure 7 6. The backward bending refers to the bending of the multi-stranded wire towards the rear of the traveling direction of the multi-stranded wire in the straight passage; the forward bending refers to the multi-stranded wire being bent on the rotating member The traveling direction after bending is consistent with the traveling direction of the multi-strand wires in the straight channel. Specifically, as shown in FIG. 7 and referring to FIG. 6 , the secondary twisting device 23 includes a hollow wire tube 2302 for feeding the multi-strand wires into the secondary twisting device. Part of the straight channel is formed; the rotating member is a twisting turntable 2301 sheathed on the wire tube 2302, and the twisting turntable 2301 can continuously rotate around the wire tube 2302; as shown in FIG. The multi-strand wire of 23 is bent backward at the portion passing out of the wire tube 2302, and is bent forward on the twisting disc 2301 before being output. In this embodiment, the "N"-shaped two bends are used to ensure the clamping effect on the multi-strand wires, that is, two bends are used to ensure that the multi-strand wires are added with the rotating member. The twist discs 2301 are rotated together and unwound from the winder 20 of the main twister and are clamped very securely, thereby ensuring that the secondary twist can be reliably applied to the multi-stranded wire. Of course, the implementation of the secondary twister of the present invention can never be limited to this implementation. For example, even if only one small-angle obtuse-angle bending is adopted, a method similar to that shown in FIG. It is possible to clamp the multi-strand wires well, or it is also feasible to use three or even more bending mechanisms with more large-angle acute-angle bending than "N" type bending. This has also been detailed in the description of Figures 7 and 8 in this section.

Finally, the present invention also provides a twisting machine, as shown in FIG. 4 and referring to FIG. 6 and FIG. 1 , the twisting machine uses the aforementioned twisting device, and the twisting device may only include main twisting The twister can also include a primary twister and a secondary twister at the same time. Referring to Fig. 4, the twisting machine using the twisting device can easily integrate the yarn doubling process and the twisting process of the traditional double twisting machine in one go, and can also completely transmit the spun yarn of the ring spinning frame. The two processes of winding and winding are integrated into a single twisting machine and completed in one step. As shown in Figure 4, it is only necessary to provide two sets of winding devices for feeding the multi-stranded wire to the twisting device and pulling and collecting the twisted multi-stranded wire from the twisting device. In the second embodiment, both sets of winding devices are implemented by a pair of winding rollers 12. Of course, this is only an implementation method. In reality, the winding device can be completely different from a pair of winding rollers. For example, The aforementioned tightening of the twisted multi-strand bobbin 6 directly on a drum and continuous rotation can also realize the pulling of the multi-strand yarn from the twisting device and match it as shown in Figures 1 and 4. The transverse yarn guide device 13 has the effect of winding the multiple strands into a regular-shaped twisted multiple strand bobbin 6, and so on.

When actually using the twisting machine equipped with this embodiment, as shown in FIG. 4 and referring to FIG. 3 , firstly, loosen the pair of winding rollers 12 of the winding input device that conveys the multi-strand wire to the twisting device, and use One end of an elastic steel wire is tied with a multi-strand wire or a roving that is merged from two single-strand bobbins 1, and the other end is penetrated into the corresponding rotating shaft 18 from the bottom of the rotating shaft 18 and sequentially passes through as shown in Figure 4. The hollow channel 1808 of the rotating shaft 18, the channel 180101 of the yarn guide block 1801, the transverse channel 190302 at the bottom of the drum 1901, the vertical channel 190301 on the wall of the drum 1901, and then the whole elastic steel wire is removed from the vertical A long section of multi-strand yarn is drawn out from the channel 190301 and pulled out; then use both hands to rub the multi-strand yarn pulled out from the drum 1901 to make it rotate according to the rotation of the rotary twister 19 when the twisting machine is started. A certain degree of manual twisting is performed on the multi-strand yarn in the twisting direction, and then the long section of multi-strand yarn is manually wound on the yarn winding drum 2001 according to the winding of the yarn on the yarn winding drum 2001 when the twisting machine is started. The direction of winding is tightly wound on the yarn winding drum 2001 for several turns, and the multiple strands between the yarn winding drum 2001 and the rotating drum 1901 must have a certain tension, and the yarn is wound on the yarn winding drum 2001. The multi-turn multi-strand wire can be stacked to a certain extent so that the multi-strand wire wound on the yarn winding drum 2001 will not be easily scattered, and it can also be collected by the winding device with a certain pulling tension. The yarn bobbin 2001 is drawn and unwound, and in order to generate the tension of the multiple strands between the yarn winding bobbin 2001 and the rotating drum 1901, the multiple strands can be transported to a part of the twisting device. The winding rollers 12 are clamped with sufficient clamping force. If the twisting device is equipped with the pinch roller 2004 as shown in FIG. 6 , it is more convenient to wind the multiple strands on the yarn winding drum 2001 relatively stably, and of course wind the multiple strands to the yarn winder. When above 20, the pinch roller 2004 needs to be pulled away from the yarn winder 20 first. Next, the elastic steel wire is used to guide the long multi-strand wire that is not wound on the bobbin 2001 through the gap between the magnetic attraction ring 2103 and the central axis fastener 2103. If the twisting device If a secondary twister is provided in addition to the main twister, the multi-strand wires are drawn through the secondary twister by the elastic steel wire, and then the multi-strand wires are passed through the spool ring shown in Figure 4. The pair of winding rollers 14 and the pair of winding rollers 12 that pull and collect the twisted stranded wire securely wind the stranded wire on the twisted stranded bobbin 6 . At that time, the initialization of the twisting machine is completed, and the twisting machine can be started. One or two of the transmission belts 10 start to continuously travel after the twisting machine is started to drive the main twister or the main twister and the second twister. The road twister starts working to perform a continuous rotary twisting operation on the multiple strands. Considering that it is very easy to unwind the single-strand thread from the single-strand spool 1, the multi-strand thread formed by combining multiple single-strand threads at the spool ring 14 shown in FIG. The bend of the channel 180101 of the block 1801 may not be able to form an effective tightening effect to generate the radial clamping force necessary for the rotation and twisting. In actual use, the roller 12 needs to adjust its clamping force on the multi-stranded wire so that it will not only not obstruct the multi-stranded wire winding formed by the differential speed between the yarn winder 20 and the rotary twister 19, It is also necessary to retain a slight clamping force suitable for the multi-stranded wire so that the multi-stranded wire traveling in the yarn guide block 1801 will generate the aforementioned radial clamping force at the bend in the channel 180101. Currently, the paired winding rollers The clamping force between the two is usually provided by a spring, so it is also easy to adjust the clamping force of the pair of winding rollers 12 for conveying the multi-stranded wire to the rotating shaft 18 as shown in the lower part of FIG. Adjust the elastic deformation of the spring or select springs of different specifications. In fact, the better working condition of the pair of winding rollers 12 is that the speed of rotating and conveying the multi-strand wire is only higher than that of the differential transmission device 22 to pull the multi-strand wire. The speed of winding onto the yarn winder 20 is slightly lower and the clamping force of the pair of winding rollers 12 on the multi-strand wire is adjusted so that the differential transmission device 22 can easily overcome the force of the pair of winding rollers 12. The clamping force pulls and winds the multi-stranded wire onto the yarn winder 20. With the current mature motor drive technology and the aforementioned spring elastic force adjustment method, the rotational conveying speed of the multi-stranded wire of the pair of winding rollers 12 and the multi-stranded wire are improved. The clamping force of the wire can be fully adjusted to the aforementioned conditions, so as to ensure that there is an axial tension required for rotary twisting at the multi-strands fed into the rotary twister 19 and bent therein to ensure the rotation The twister 19 applies a twisting effect of one turn and a single twist to the multiple strands fed into it for the first time. Of course, when the traditional differential device 22 indirectly unwinds the single-strand wire from the single-strand bobbin 1, the unwinding resistance that needs to be overcome is sufficient to tension the multiple-strand wires everywhere. The drawing of the pair of winding rollers 12 shown is entirely dependent on the difference in rotational speed between the winder 20 and the rotary twister 19 to achieve the input drawing of the stranded wire. During the operation of the twisting machine, the speed of the gripping and pulling of the multi-stranded wire by the pair of winding rollers 12 shown in the upper part of FIG. 4 needs to be finely adjusted to precisely control the multi-stranded wire from the winding. The speed of unwinding on the yarn reel 20 is approximately equal to the speed at which the differential drive winds the multiple strands from the rotary twister 19 onto the yarn winder 20, so that the winding is The several turns of the multi-stranded wire on the yarn winder 20 can generate enough friction through the winding extrusion between the multi-stranded wires to ensure that the multi-stranded wire output from the rotary twister 19 can be smoothly wound on the winding. There is no slippage on the yarn winder 20, and it can also ensure that the pulling force required to unwind the multi-strand yarn from the yarn winder 19 is not too large, because if the yarn wound on the yarn winder 20 is If the number of multi-strand coils and the number of layers in the stacked winding is too large, the pulling force required for the multi-strand unwinding will be greater, and it will also lead to different areas of the degree of twisting of the multi-strand in the main twister. unevenness across the segment. In a nutshell, in actual production, when the twisting machine is initialized, it is necessary to wind a sufficient number of turns of the multi-stranded wire on the yarn winder 20 to ensure that the multi-stranded wire wound on the yarn winder 20 is fastened to the The yarn winder 20, then pay attention to setting the speed of the winding device represented by a pair of winding rollers 12 on the top of FIG. The upper winding speed is roughly equal and not too fast or too slow, so that it can not only ensure that the multi-strand yarn can be smoothly and continuously wound from the rotary twister 19 to the yarn winder 20, but also ensure that FIG. 4 The winding device for the twisted multi-ply yarns represented by a pair of winding rollers 12 above can continuously unwind the twisted multi-ply yarns from the yarn winder 20 smoothly. In the second embodiment, the outer shape of the winding drum 2001 of the core yarn winding component of the yarn winder 20 is designed as shown in FIG. 3 to FIG.

The collecting and winding device represented by a pair of winding rollers 12 at the top of FIG. 4 not only acts as a power provider for unwinding the multi-strand yarns from the winder, but actually also draws the multi-strand yarns into the subsequent two channels. The twister 23 is ultimately output to the power provider on the final product package represented by the twisted bobbin 6 in FIG. 4 . When running the twisting machine using the twisting device provided by the present invention, the purpose of finely and dynamically adjusting the instant speed at which the multi-ply yarn collecting and winding device pulls the multi-ply yarn unwinding from the yarn winder 20 is as follows: On the one hand, it is to ensure that the unwinding can be carried out smoothly without unwinding because the number of layers wound on the yarn winder 20 is too large and too thick to be unwound, and on the other hand, it is also to ensure that the multiple yarns are wound on the yarn winder 20 The number of turns or layers is sufficient to ensure that the multiple strands can be tightly wound on the winder 20 to ensure the rotation between the twister 19 and the winder 20 generated by the differential transmission 22. The coaxial and co-rotating differential speeds can smoothly pull out the multi-strand yarns from the rotary twister 19 and wind them onto the yarn winder 20 . For the twisting machine using the twisting device provided by the present invention, by adjusting the transmission ratio of the differential transmission device 22, the twisted multi-stranded wire is collected to the twisted multi-stranded wire shown in FIG. 4 . Parameters such as the pulling speed of the winding device of the final product package yarn represented by the tube 6 and the rotational speed of the rotating shaft 18 can realize the twisting effect of any degree set for the multi-strand yarn.
