Description

Twisting device and twisting machine adopting same

Technical Field

The invention belongs to the field of textile equipment, and particularly relates to a Twisting device (English is 'Twisting device') and a Twisting machine (Twisting machine) using the Twisting device.

Background

The textile industry typically requires twisting of single-strand yarns to wind and twist two or more single-strand yarns into a yarn prior to spinning with the yarns. In the spinning process, the sliver (strand, yarn, thread) is twisted or axially wound around its axis to obtain "twist" or wrapping, which is called "twisting". The twisting can make the fibers or the monofilaments cohere and intertwined with each other without loosening or slipping, and has certain physical and mechanical properties (such as strength, elongation, elasticity and the like) and appearance characteristics (such as luster, hairiness, hand feeling and the like). At present, the main twisting equipment mainly comprises a two-for-one twister and a ring spinning frame. The name of the two-for-one twister is derived from that a spindle (English is called "spindle") twisting device used by the two-for-one twister can realize the twisting effect of one-for-two twisting for parallel multi-strand wires input into the spindle twisting device, besides the spindle twisting device, the two-for-one twister and almost all types of twisting machine equipment also comprise a "collecting and winding device" which actively draws, collects and winds the twisted multi-strand wires output from the spindle twisting device into a finished twisted multi-strand wire barrel, wherein the collecting and winding device usually comprises a Roller which continuously rotates (English is called "Roller", Chinese is interpreted as "Roller") or a pair of rollers which are tightly attached and rotate in opposite directions, and the rollers are usually called "winding rollers" in the textile industry. The strands fed to the two-for-one twister are subjected to a continuous pulling action by the collecting and winding device, whether it takes the form of a single roller or a pair of counter-rotating rollers or even any other type of arrangement. When the collecting and winding device adopts the arrangement of a single roller, the finished product twisted multi-strand bobbin can continuously rotate along with the single roller, so that twisted multi-strand wires which are twisted and output by the twisting device are continuously pulled out and wound into the final finished product twisted multi-strand bobbin; when a pair of oppositely rotating rollers is adopted, the twisted multi-strand yarn which is twisted and output by the twisting device is clamped by the two rollers, is continuously pulled out from the twisting device and is then wound into a twisted multi-strand bobbin. The ring spinning frame adopts a spindle twisting device which is different from a two-for-one twister and can only realize the twisting effect of one-for-one twisting, and the spindle twisting device of the ring spinning frame, which comprises a spindle for driving a central quill of a cop to continuously rotate, a steel wire ring for drawing raw material roving to continuously rotate and twist and a rotating track steel collar of the steel wire ring, is used for twisting the raw material roving into spun yarn and winding the spun yarn into cop, and then a plurality of cops are connected on a winding machine to form the cheese of the spun yarn.

The two-for-one twister and the ring spinning frame as described above require two processes in actual production, and for the two-for-one twister, in addition to the twisting process itself, a "doubling" process of combining the multiple strands to be twisted into one parallel multiple strand and winding the multiple strands into a parallel multiple bobbin must be performed before the twisting process; for the ring spinning frame, the diameter of the cop affects the twisting degree and the twisting speed of the multi-strand yarn, so that the twisted spun yarn which can be wound on the cop cannot be too much, and the cop produced from the ring spinning frame must be subjected to a process commonly called spooling to connect the ends and the tails of the fine yarns on a plurality of cops and wind the cops into the final finished product cheese.

In summary, the two traditional twisting devices, the two-for-one twister and the ring spinning frame, are really ingenious, but the defects are obvious, that is, both of them require two different processes, for example, the two-for-one twister needs two processes of doubling and twisting, the ring spinning frame needs a process of spinning and spooling, the different processes mean the energy consumption of different sites, production devices and two sites, if the final twisted multi-strand bobbin can be directly generated from a plurality of yarns or a plurality of fibers in one step or the final finished spun bobbin yarn from roving to the final finished product can be finished at one step, half of the site and power can be saved, and the economic benefit is greatly improved.

Disclosure of Invention

In order to solve the defects of the conventional twisting equipment including the two-for-one twister and the ring spinning frame pointed out in the section of the background art, the twisting device and the twisting machine adopting the twisting device provided by the invention can combine two processes required by the conventional two-for-one twister and the ring spinning frame into a whole, directly produce finished twisted multi-strand bobbins from a plurality of raw material bobbins in one go, or produce finished spun yarn bobbins from roving bobbins in one step.

Specifically, the present invention provides a twisting device, which, like the presently disclosed twisting solution, also includes a twister for twisting and outputting the multiple strands inputted into the twisting device, and a support of the twister, where a "thread" of the multiple strands refers to any fiber product, such as sliver, roving, silk, thread, etc., which is twisted in the textile industry, and the support of the twister is actually used to mount the twisting device on the twisting machine. Different from the traditional two-for-one twister and the ring spinning frame and all the twisting technical schemes disclosed at present, the technical characteristics of the twisting device provided by the invention are that the twister comprises a rotary twister which can carry out twisting operation on the multi-strand input into the twister through rotation, and the multi-strand input into the rotary twister can be wound, and when the rotary twister rotates, the wound multi-strand can be unwound and output from the inside of the wound multi-strand after a bend is generated. All twisting machines, as described in the background section above, are equipped with the take-up winder, which, as described above, continuously draws the strands. It is conceivable that the multi-strand wires are under tension at the bending positions due to the pulling force of the collecting and winding device and the pulling force of the two sides of the friction force of the wound multi-strand wires, the multi-strand wires at the bending positions generate acting force on the contact surfaces of the multi-strand wires for bending due to the tension, and the acting force reacting on the multi-strand wires clamps the multi-strand wires, so that the effect is as if the multi-strand wires are pinched by two fingers. The twisted multi-strand can generate twisting effect by continuously rotating the pinched multi-strand along with the rotation of the rotary twister, and the twister included in the invention can continuously generate twisting on the multi-strand between the bending part and the collecting and winding device along with the continuous rotation of the rotary twister, because the multi-strand is clamped at the roller of the collecting and winding device; it is in fact possible to produce a twisting effect by pinching two of the strands with two hands and rotating one of the hands. The invention is to prevent the multi-strand wires output by the rotary twister from interfering with the multi-strand wires to be wound, because the multi-strand wires can be wound together from three hundred and sixty degrees, and the multi-strand wires can be bent and output from the middle of the winding part, so that the interference with the multi-strand wires around the multi-strand wire winding part can be avoided. The rotary twister is the core component of the twister of the twisting device provided by the invention, and the rotary twister can be actually called the rotary twisting component of the core of the twister. In order to allow the multi-strand input to the twisting apparatus provided by the present invention to be wound on the rotary twister, in the present invention, the twister further includes a winder for winding the multi-strand input to the twister on the rotary twister, although the rotation of the rotary twister may also contribute to winding the multi-strand thereon.

As a preferred embodiment of the above technical solution of the present invention, the winder is designed and manufactured to preferentially wind the multiple strands on the rotary twister by rotating. As described above, the friction between the twisted strands wound around the rotary twister and the rotary twister or the friction between the twisted strands and the collecting and winding device of the twister can make the twisted strands receive pulling force everywhere so as to achieve the effect of tightening the twisted strands when the twisted strands are bent, the tightened twisted strands can generate the clamping effect on the twisted strands, and the tightened twisted strands can generate the twisting effect when rotating together with the rotary twister. Although a manipulator or some other mechanical mechanism can be used for winding the strands together, the winding of the strands in a rotating manner is a simple, direct and natural manner, and theoretically, the strands can be drawn out from the winder and wound on the rotating twister only if a difference of one point exists between the turning direction and the rotating speed of the winder and relevant parts of the rotating twister, and the corresponding electromechanical design mechanism is simple and practical.

In a preferred embodiment of the above-described rotary type winder according to the present invention, the rotary twister is designed such that the direction of the axis of rotation thereof is preferably aligned with the direction of the axis of winding of the multiple strands fed to the rotary twister during design and manufacture. The axial lead direction of the rotating shaft of the rotary twister is consistent with the axial lead direction of the winding of the multiple strands, which means that the rotary twister can synchronously realize the winding of the multiple strands along the belt when the rotary twisting is carried out on the multiple strands, thus simplifying the twisting process and simplifying the electromechanical design structure of the rotary twister.

As a typical embodiment of the above-mentioned technical solution of the rotary type winder of the present invention, the winder may include a conduit for guiding the strands inputted to the twister to the outer periphery of the rotary twister, that is, the strands inputted to the twister may penetrate the conduit and reach the outer periphery of the rotary twister through an opening at one end of the conduit. The wire guide may be rotated around the rotary twister to wind the strands output from one end opening of the wire guide around the rotary twister. In fact, the twisting device may be wound on the conduit as long as there is a difference in the direction of rotation or the speed of rotation between the conduit and the rotating twister, and it is a matter of course that the rotating twister must be used by an initialization operation, for example, the collecting and winding device should be allowed to exert a moderate pulling force on the strands in the rotating twister when the collecting and winding device is performing the initialization operation of the rotating twister, for example, the strands are wound moderately around the strand winding portion of the rotating twister until a sufficient friction force to fix the strands relatively stably on the winding portion is generated.

As a preferred embodiment of the above technical solution of the present invention, the conduit is fastened to a hollow rotating shaft, and the hollow channel inside the conduit is communicated with the hollow inside of the rotating shaft, so that the multi-strand yarn input to the twisting device can penetrate into the conduit via the hollow inside of the rotating shaft and then reach the periphery of the rotating twisting device via an opening at one end of the conduit, and the rotating shaft can rotate continuously to drive the conduit to rotate continuously. There are many possibilities for driving the rotation of the shaft and the conduit, such as a gear drive, a pulley drive, etc.

In a preferred embodiment of the rotary twister according to the present invention, the rotary twister comprises a hollow winder on which the multiple strands fed to the twister are wound by the winder. The winder can be continuously rotated, and the winder which is matched with the winder for realizing the winding of the multi-strand wires in a rotating mode can realize the winding of the multi-strand wires on the winder as long as the difference exists between the winder and the winder in the turning direction or the rotating speed. Of course, in the present embodiment, the multiple strands wound on the reel can be unwound from the reel and be output from the hollow interior of the reel after one-fold bending occurs while the reel continues to rotate. In this preferred embodiment of the rotary twister, the power for unwinding the stranded wires can come from the collecting and winding device, as long as the pulling force of the collecting and winding device on the stranded wires is larger than the friction force between the wound stranded wires and the winding position thereof and the friction force between the wound stranded wires, and the unwound stranded wires can naturally form a bend as long as being output from the interior of the winder, and after all, the winding position of the stranded wires is located on the outer surface of the winder, so that the embodiment of the invention is completely feasible and mechanically quite simple and unsophisticated.

As a preferable embodiment of the above technical solution using the reel, the rotary twister includes a hollow shaft, the hollow shaft is tightly inserted into the hollow of the reel, and the hollow shaft can rotate continuously to drive the reel to rotate continuously. Therefore, in this embodiment, the winder can continuously rotate as long as the hollow rotating shaft is driven to continuously rotate, and the routing channel formed by the hollow part of the hollow rotating shaft can provide a path for outputting the stranded wires.

In addition, when the technical solution of the cord reel is adopted, in the case of the cord reel, a typical embodiment is that the external shape of the cord reel is to be tapered, in which a multi-strand wound on the cord reel via the cord winder is first wound on one end of the taper near its large diameter, and the multi-strand wound on the cord reel is unwound to be bent into the opening of the tapered end near its small diameter and to be output from the opening of the tapered end near its large diameter through the entire hollow interior of the cord reel. The reason why the reel is preferably made to have a tapered shape is to facilitate unwinding of the strands and to prevent the strands tightly wound together from being cut off by the collecting and winding device due to over-tightening of the winding, because the strands are wound on the reel from the end of the tapered shape of the reel close to the large diameter end, the strands wound on the reel slip and unwind toward the small diameter end of the tapered shape under the pulling action of an external force and slip from the large diameter end to the small diameter end is smooth, and of course, the twisting device of the present invention needs to wind a few turns of strands slightly more at the large diameter end of the tapered shape to generate enough friction force to prevent the strands from being easily unwound automatically and loosely from the reel.

In a preferred embodiment of the above-described solution of the invention using a conduit, the conduit is preferably designed and manufactured in a centrally symmetrical U-shape, which helps to keep the conduit in a balanced position during high-speed rotation and to prevent the guide tube from being unnecessarily thrown off in its installed position.

Finally, the invention also provides a twisting machine, which comprises a frame and the twisting device for twisting the multi-strand wires, wherein the twisting device is used for twisting the multi-strand wires, so that the twisting machine adopting the twisting device can conveniently integrate the doubling process and the twisting process or the spinning process and the winding process for twisting the roving into the spun yarn into a single process.

In summary, the twisting device and the twisting machine provided by the invention can perfectly inherit the twisting principle of a mature two-for-one twisting machine and a mature ring spinning machine and combine the twisting machine and the ring spinning machine into a whole, and can conveniently integrate two processes required by the traditional two-for-one twisting machine and the ring spinning machine into one twisting machine to finish the two processes at one time, successfully utilize a single twisting machine to realize the production target of two separate processes of the traditional two-for-one twisting machine and the ring spinning machine in one step, save the field, and also save the consumption of power energy and the corresponding labor cost.

As shown in fig. 1 and referring to fig. 2 and 3, in the present embodiment, the winder 2 of the twisting device 0 of the present invention winds the multiple strands 13 on the winder 101 of the rotary twister 1 in a rotating manner, and the U-shaped central symmetry structure of the conduit 201 also ensures that the winder 2 can be well balanced during high-speed rotation without throwing off the relevant parts due to excessive single-side centrifugal force. In the embodiment shown in fig. 1 and 2, a hollow wear-reducing porcelain ring 2014 capable of reducing the friction force of the stranded wires 13 is inserted into an opening of the rotating shaft 2011 of the bobbin 2, which is connected with the conduit 201, surfaces of inner walls of the wear-reducing porcelain ring 2014, which are in contact with the stranded wires, are covered with a smooth glaze, a similar wear-reducing porcelain ring 2014 is inserted into the opening of the conduit 201, and the wear-reducing porcelain ring 2014 is usually installed at a bent part of a traveling path of the stranded wires 13, so that the stranded wires 13 are prevented from being easily broken, and meanwhile, the resistance of the stranded wires 13 to being pulled and traveling is also reduced.

As shown in the figure and referring to fig. 2, in this embodiment of the present invention, the twister 0 of the twisting apparatus, that is, the winder 101, achieves the purpose of winding the multiple strands 13 entering the rotary twister 1 and then outputting them from the inside of the wound multiple strands 13 while being twisted into twisted multiple strands 14.

Fig. 2 is a schematic view of the twisting principle of the twister of the first embodiment of the twisting device provided by the invention. Fig. 2 is divided into three views by two vertical dot-dash lines, the left view at the leftmost side is a separated view of the rotary twister 1 and the winder 2 of the embodiment shown in fig. 1, the left view also shows that the rotary twister 1 and the winder 2 are all components of the twister 0 by a frame line, and the reader can clearly identify the components of the twister 0 of the twisting device provided by the invention by combining fig. 1 and fig. 3; the view in the middle of the two vertical dot-dash lines shows a schematic view of the twisting device and the multi-strand 13 which is input into the twisting device 0 during operation being wound, passed through or twisted into the twisted multi-strand 14, while the right view in the right side of the figure shows a schematic view of the principle of the multi-strand 13 which is input into the twisting device during operation being wound, passed through or twisted into the twisted multi-strand 14. As shown in fig. 2 and referring to fig. 1, 3 and 7, when the twisting machine using the twisting device provided by the present invention is used, a twisted finished bobbin 9 can be produced from a plurality of raw bobbins 8 in one go, and if a conventional two-for-one twister or a ring spinning frame is used, at least two sets of equipment are required to complete two processes one after another. As shown in the present figure and referring to fig. 1, 3 and 7, for the twisting machine using the twisting device provided by the present invention, raw material yarns from a plurality of raw material bobbins 8 are firstly combined into a multi-strand 13 by a simple doubling device, and then the multi-strand can be wound into a twisted finished bobbin 9 after passing through the twister 0 of the twisting device, in this embodiment, the doubling device is the hub 3 located above two raw material bobbins 8 as shown in fig. 2 and 3, namely, a circle, the raw material yarns from different raw material bobbins 8 pass through the inside of the circle of the hub 3 together, namely, are combined into a whole multi-strand 13 to be twisted, the multi-strand 13 firstly enters the rotating shaft 2011 of the winder 2 as shown in fig. 1 to 3, then the conduit 201 penetrating the winder 2 is output to the periphery of the rotating twister 1 of the twister 0 of the twisting device, the strands 13 can be wound on the rotary twister 1 when there is a difference in the direction of rotation or the speed of rotation between the rotary twister 1 and the winder 2 as described above, as shown in fig. 2 and referring to fig. 1, 3 and 7 for the first embodiment, it is only necessary that the rotation speed of the wire conduit 201 of the wire winder 2 is different from the rotation speed of the reel 101 of the rotary twister 1, as shown by an arc arrow at the lower side of the line reel 101 in the right view of fig. 2, when the line reel 101 is installed and rotated in the direction shown by the arc arrow, when the rotation speed of the same direction rotation of the conduit 201 is slightly less than the rotation speed of the reel 101, the stranded wire 13 inserted into the conduit 201 is drawn out of the conduit 201 and wound on the reel 101, in this way, the winder 2 performs the aforementioned function of winding the strands around the rotary twister. Of course, when the twisting device and thus the twisting machine are initialized, it is necessary to wind the multiple strands 13 on the winder 101 for multiple turns to generate enough friction force to ensure that the wound multiple strands form a relatively stable entity so that the twisting device and the twisting machine using the twisting device can pull the multiple strands 13 out of the conduit 201 during operation. Certainly, in actual production, the rotation directions of the rotary twister 1 and the winder 2 are not necessarily in the same direction, the rotation speeds of the rotary twister 1 and the winder 2 can be freely set, even in the actual production process, the rotation directions can be switched and the rotation speeds can be adjusted according to the signal dynamics of a related sensor, only the rotation directions of the motors driving the rotary twister 1 and the winder 2 to rotate need to be finely taught, and the transmission wheels of the rotary twister 1 and the winder 2 in the first embodiment are provided with gear tooth structures meshed with the synchronous belt, namely, the gear tooth structures are used for ensuring the accurate control of the rotation speeds of the rotary twister 1 and. As shown in fig. 2 and referring to fig. 1, 3 and 7, in the first embodiment, the rotary twister 1 of the twister 0 uses a winder 101 to achieve the purpose of winding a plurality of strands thereon and then bending the strands from the inside of the winding shape and outputting the bent strands to a collecting and winding device of the plurality of strands, and although the rotary twister 1 and the winder 101 thereof all adopt a tapered shape in all the drawings, it should be noted that the shape of the rotary twister 1 and thus the winder 101 is not necessarily changed or improved in the actual implementation of the present invention, as long as the function of winding the plurality of strands thereon and outputting the strands from the inside of the winding shape is achieved, and other shapes and further improved technical measures are also possible. The middle view and the right view in the figure also show that the multi-strand collecting and winding device installed on the twisting machine provided by the invention comprises a wire collecting ring 3 which is driven by a bidirectional air cylinder 7 to slide back and forth and a motor 5 which is used for driving a finished twisted bobbin 9 to rotate continuously to draw and collect twisted multi-strands, the wire collecting ring 3 slides back and forth under the driving of the air cylinder 7 to promote the twisting finished bobbin 9 to generate a regular conical shape, of course the middle and right views of figure 2 only show one possible realisation of the collecting and winding device, in the embodiment, it can be realized in other ways, for example, two rollers rotating in opposite directions, which are closely attached to each other as shown in fig. 7, hold the twisted multi-strand and continuously pull it out of the twisting device and collect the multi-strand bobbin 9 wound as the final product. As shown in the right view of fig. 2 and referring to fig. 1, 3 and 7 and as mentioned above, the twisted yarn 13 unwound from the winding position of the twisted yarn 13 enters the inside of the wound twisted yarn after being bent, that is, the inside of the cord reel 101 and the hollow rotating shaft 1011 in the first embodiment, the twisted yarn 13 is actually tensed everywhere due to the continuous pulling of the collecting and winding device, a pressing force is generated on the surface of the contacted component at the bent position, and the reaction force of the pressing force acts on the twisted yarn 13 at the bent position to clamp the same, the twisted yarn 13 is clamped at the hollow antifriction ceramic ring 1014 in the first embodiment, and the twisted yarn 13 is twisted with the rotation of the rotary twister 1 and thus the cord reel 101 as shown in the right view of fig. 2 to form the twisted yarn 14 as shown in the right view of fig. 2, in fact, for the present embodiment, the twisting position of the multi-strand is in the hollow channel of the hollow rotating shaft 1011 of the rotary twister 1. For example, the twisting principle of the present embodiment is equivalent to that one end of a segment of multi-strand is pinched by one hand at the position of the finished twisted bobbin 9 shown in the view of fig. 2 and the right view, while the other end of the segment of multi-strand is pinched by the other hand at the position of the antifriction ceramic ring 1014 shown in fig. 1 and fig. 2 and continuously rotated, so that the segment of multi-strand located between the two hands can be effectively twisted, i.e. the multi-strand located in the hollow rotating shaft 1011 can be rotated and twisted from the position of the antifriction ceramic ring 1014 until the collecting and winding device collects and winds the segment of finished twisted bobbin 9 into the finished twisted product. As shown in the middle view and the right view of fig. 2 and fig. 3 and 7, in the present invention, the rotation speed of the rotary twister 1 and the pulling and collecting speed of the collecting and winding device to twist the twisted strands 14 can determine the twisting degree of the strands, and the difference between the turning rotation speeds of the winder 2 and the rotary twister 1 can determine the winding speed of the strands 13 on the rotary twister 1 and the dynamic winding number in time unit, and the multi-strand pulling and collecting speed of the collecting and winding device and the turning rotation speeds of the rotary twister 1 and the winder 2 as shown in the middle view and the right view of the present figure and referring to fig. 3 can be precisely adjusted or switched by only controlling the turning rotation speed of the motor 5 as shown in all the figures of the specification.

Fig. 3 is a schematic view of a first exemplary embodiment of a twisting machine using a twisting device provided by the present invention. A first embodiment of the twister provided by the present invention employs the first embodiment of the twisting means described in the preceding figures. In fig. 3, which is a detailed representation of the middle and right side views of fig. 2, the frame 4 of the twister, which is not shown in fig. 2, the motor 5 and the belt 6 for driving the rotary twister 1 and the winder 2 to rotate, and the like are shown to the reader in this figure. As shown in fig. 3 and shown in fig. 2, it can be seen that a twisting device provided by the present invention can be completely and successfully implemented, for the first embodiment of a twisting machine provided by the present invention, it is only necessary to respectively sleeve the synchronous transmission belts 6 on the transmission wheels of the rotary twister 1 and the winder 2 and match with the respective motors 5, although fig. 3 only shows one twisting device provided by the present invention, actually, the twisting machine using the twisting device can be completely designed into an array of twisting devices to form a large-scale twisting production line, and can also be completely further improved by, for example, adding various sensors or using a distributed Control System (usually abbreviated as DCS). As shown in fig. 3, the two transmission belts 6 are marked with arrows to indicate a typical transmission direction, and the arc-shaped arrows are also arranged below the U-shaped conduit 201 and the winder 101 to indicate the rotation directions of the conduit 201 and the winder 101, as shown in fig. 3 and combined with fig. 2, it can be known that the twisting device comprising the rotary twister 1 and the winder 2 and the twisting machine using the twisting device provided by the invention can completely produce twisted finished bobbins 9 from a plurality of raw material bobbins 8 in one step, and as mentioned above, the defect that two separation processes are required in the conventional two-for-one twister and ring spinning frame is overcome, and the investment of field, equipment, power and even manpower is greatly saved. The twisting machine shown in fig. 3 also shows a modification which can be adopted in the implementation, that is, the raw material bobbin 8 is arranged on a rotary table 10 which is driven to rotate as shown in fig. 3, and the twisting effect of the multiple strands can be enhanced along with the rotation of the rotary table 10 in the actual production. Specifically, in the production, the operator is required to perform the initialization operation of the twisting machine and thus the twisting device, referring to fig. 3, first, the raw material yarns on the raw material bobbins 8 are gathered and passed through the hub 3 to form a multi-strand bundle with reference numeral 13, then the multi-strand 13 is tied to one end of an elastic slender steel wire, the slender steel wire is used to guide the multi-strand 13 to sequentially penetrate into the rotating shaft 2011 of the winder 2 and the conduit 201 and output from the opening of the conduit 201, then the multi-strand 13 output from the conduit 201 is tightly wound on the winder 101 of the rotary twister 1 for multiple turns, and then the multi-strand 13 is guided by the slender steel wire to reach the finished twisting bobbin 9 through the hollow rotating shaft 1011 inside the winder 101 and is manually rotated, rubbed and twisted and tightly wound on the finished twisting bobbin 9, if the multi-strand collecting and winding device with a pair of rollers or other type of rollers as shown in fig. 7 is used for clamping or clamping the multi-strand collecting and winding device It is then necessary to ensure that the strands pass through the nip and are then wound onto the final twisted bobbin 9 when initialised. When the initialization is completed, the collecting and winding device is ensured to generate a proper pulling force on the strands to ensure that the strand bent and output from the inside of the strand winding shape of the rotary twister 1 is in a proper tight state rather than a loose state, then the twisting machine is started to start the production of the stranded twisting bobbin 9, and then the power for the strands 13 to travel from the doubling device shown above the raw material bobbin 8 in the form of the thread-collecting ring 3 to the finished twisting bobbin 9 as the final product comes from the collecting and winding device, and as mentioned above, the collecting and winding device can adopt a mode that one roller drives the finished twisting bobbin 9 to rotate so as to continuously pull the strands, or a mode that a pair of rollers rotating oppositely as shown in fig. 7 continuously clamp and pull the strands, or other modes, for example, a belt is tightly attached to a roller and drives the roller to continuously rotate, and meanwhile, the belt and the roller tightly clamp the stranded wires, so that the effect of pulling and collecting the stranded wires can be realized. Note that two arc arrows are shown, a large arc arrow shows the rotation direction of the wire conduit 201 of the wire winder 2 and the core thereof, and a small arc arrow shows the rotation direction of the wire reel 101 of the rotary twister 1 and the core thereof, and referring to fig. 1 and 2, in this embodiment shown in fig. 4, the multi-strand wire 13 can be continuously pulled out of the wire conduit 201 and wound on the core member reel 101 of the rotary twister 1 as long as the rotation speed of the wire conduit 201 is greater than the same direction rotation speed of the reel 101. Finally, please note that the twisting device and the twisting object of the twisting machine using the twisting device provided by the present invention are not limited to the multi-strand raw material yarn shown in fig. 3, but can also be a single strand roving to be twisted, that is, the present invention can also completely replace a ring spinning frame to twist the single strand roving into a finished spun yarn bobbin, and referring to fig. 3, only a plurality of raw material bobbins 8 need to be replaced by one roving.

Fig. 4 is a schematic view from below of the bottom structure of the turntable of the embodiment of the twisting machine shown in fig. 3. Fig. 4 mainly illustrates a possibility that a plurality of raw material bobbins 8 may be simultaneously rotated to achieve, for example, a twist of a yarn drawn from a single raw material bobbin, or to facilitate unwinding of the yarn from the raw material bobbin 8, or the like, in addition to continuously and synchronously rotating around a central axis in the production of the twisting machine provided by the present invention. As shown in fig. 4, the bottom of the rotary plate 10 has a fixed ring 11 which does not rotate with the rotary plate 10, the fixed ring 11 can be fastened to the frame 4 of the twisting machine in the embodiment of the twisting machine provided by the present invention, i.e. can keep it from rotating with the rotary plate 10, furthermore, the central yarn tube of a raw yarn tube with reference number 8 in fig. 4 is fastened to a rubber roller 12, the roller 12 is tightly attached to the fixed ring 11, so that when the rubber roller 12 rotates with the rotary plate 10, it will rub against the fixed ring 11 and rotate, and the rotation of the rubber roller 12 will drive the central yarn tube of the raw yarn tube 8 to rotate together, thereby realizing the rotation of the raw yarn tube with reference number 8.

Fig. 5 is a schematic view of a second exemplary embodiment of a twisting machine using a twisting device provided by the present invention. The second embodiment of the twisting machine shown in this figure and illustrated in this figure is actually only to show that the installation orientation of the twisting device of the present invention is not necessarily limited to the layout of the raw material bobbin 8 on the lower twisted final bobbin 9 shown in the previous figures 1 to 3, and even the assembly orientation of the rotary twister 1 and the winder 2 of the twisting device is not necessarily completely in accordance with the layout of the winder 2 on the lower rotary twister 1 shown in figures 1 to 3, and with reference to figure 7, the technical idea at the core of the present invention is that the winding of the multi-strand wire is generated by rotation and simultaneously the twisting operation is performed when the unwound multi-strand wire is bent and output from the inside of the wound multi-strand wire by using the rotation, essentially independent of the assembly orientation of the rotary twister 1 and the orientation of the winder and the installation on the twisting machine, and can be flexibly handled in practical terms in practical implementation, and not necessarily to all figures and all embodiments described herein. Fig. 5 is a vertical chain line which separates the left view and the right view, and the right view of fig. 5 shows the cross-sectional view of the second embodiment of the twisting device provided by the present invention, which can also be said to be the effect of the inverted assembly of the first embodiment, so the shapes of the parts of the second embodiment and the reference numbers can be corresponding to those of the first embodiment of the twisting device. The left side view of fig. 5 shows the effect of the second embodiment of the twisting machine using the second embodiment of the twisting device, which is actually the reverse of the first embodiment of the twisting machine, so that the parts such as the motor 5 and the transmission belt 6 in the figure can be corresponding.

Figure 6 is a schematic view of a third embodiment of a twisting device according to the present invention. The third embodiment shown in the figure actually illustrates another way of implementing a winder other than the conduit 201, in fact in the present invention the winder 2, i.e. an assembly that allows the strands to be wound on the rotary twister, in reference to figures 1, 2, 3 and 5, theoretically as long as this winder 2 can guide the strands 13 to the periphery of the rotary twister 1, in an extreme case the twister 0 of the twisting device provided by the present invention can allow the strands 13 to be wound thereon by means of the rotation of the rotary twister 1 even if the winder 2 stops. As shown in fig. 5, in the third embodiment of the twisting device, the strands are not guided to the periphery of the rotary twister via a pipe, but pass several rollers 15, indicated with 15, in turn and then are guided to the periphery of the rotary twister 1, and the third embodiment using the roller design has the advantage over the first and second embodiments described above in that the use of the roller 15 can greatly reduce the friction during the travel of the strands. Note that fig. 6 shows only another possible implementation of the winder in the twister of the present invention, and there are more possibilities for implementing the winder, even if it is theoretically only necessary to guide the strands to the periphery of the rotary twister 1 and ensure that the strands can be smoothly pulled out as described above.

Fig. 7 is a schematic view of an image of the principle of the twisting device provided by the present invention. The winding effect of the multiple strands 13 on the rotary twister 1 is simulated by a bobbin tightly wound around a central bobbin 16, the rotary twisting effect of the rotary twister 1 on the multiple strands 13 is simulated and demonstrated by the bobbin rotating in the direction of the upper and lower arc arrows in the figure, and the related driving mechanism for rotating the bobbin is omitted. The multiple strands shown in the figures are tightly wound around a hollow through central yarn tube 16 to form a common bobbin, i.e. a yarn bobbin commonly used in the textile industry, but the present invention is not limited to the winding and rotating form shown in fig. 7, and fig. 7 is a yarn bobbin, which is a well-known article in the textile industry, only to make the reader more quickly and deeply understand the technical principle of the present invention. In this figure a vertical dash-dotted line separates the left and right two views, the bobbin in the left view being in the form of a whole and the bobbin in the right view being in the form of a cross-sectional view, both of which illustrate the collecting and winding device, with its components such as the cylinder 7, the motor 5, the twisted final bobbin 9 and the collecting ring 3, as illustrated in the previous figures of the description, and the collecting and winding device realized with a pair of rollers rotating in opposite directions. When the strands 13 are tightly wound together for a sufficient number of turns, as shown in fig. 7, the friction between all the wound strands 13 and the winding and the friction between the wound strands during the winding time are sufficient to make the wound strands 13 form a relatively stable entity, and the entity formed by tightly winding the strands can be easily unwound only from the strands located on the superficial layer, which are shown as helical lines in fig. 7, where the conical bobbin in the figure is again emphasized only to simulate the winding effect of the strands according to the present invention. The unwound strands are bent and clamped at the bending position when being output from the inside of the wound strands, as shown in the right view of fig. 7, the unwound strands are bent verbally in the central bobbin 16 of the bobbin and output from the central bobbin 16 to the collecting and winding device, and the collecting and winding device, whether shown in the left view or the right view of fig. 7 and in any other form, applies continuous pulling force to the strands, so that the bending position of the strands is tensed and the object to which the strands are attached generates a reaction force for clamping the strands, as shown in the left view or the right view of fig. 7, the strands 13 are clamped at the verbally bent position of the central bobbin 16, and then the strands output to the collecting and winding device are twisted to form twisted strands 14 along with the rotation of the wound whole mass of strands, the twisted strands 14 are finally wound into the finished twisted bobbin 9 by the collecting and winding device, and the bobbin shown in fig. 7 is again emphasized only to demonstrate the winding and overall rotation effects of the strands, and is not intended to limit the embodiments of the present invention. As shown in fig. 7, in the present invention, the twisted strands actually provide a pulling force to one end of the twisted strands 14, while the pulling force to the other end of the twisted strands 14 is derived from the continuous pulling collection of the subsequent collecting and winding device, so as to ensure that the strands 13 are tightened and clamped when being bent into the interior of the wound strands, and then the twisting effect is generated along with the rotation. For the purposes of the present invention, the rotary twister corresponds to the bobbin shown in fig. 7, which provides the possibility of winding the strands and of bending them out of the interior of the winding site, while the rotary twister in the twisting device of the invention can also be rotated continuously, which can, on the one hand, twist the strands located between the inward bends of the strands and the collecting and winding device and, on the other hand, also make it possible to continuously supplement the winding of the strands. In fig. 7, the winder 2 of the twister of the twisting apparatus of the present invention is shown with a double wave wire omitted to show the winding and twisting principle of the rotary twister, but a reference numeral 2 is added to the wave wire as the identifier of the winder, and it is noted that the winder 2 of the twisting apparatus of the present invention theoretically winds the multi-strand wire on the rotary twister 1 by using the rotation of the rotary twister 1 itself even if it is stopped, as long as the winder 2 guides the multi-strand wire to the periphery of the rotary twister 1. Of course, the winder 2 may also use a manipulator or the like to wind the multi-strand onto the rotary twister 1 as shown above, and when the winder uses a rotary method to wind the multi-strand onto the rotary twister, the rotary twister and the winder only need to have different rotation directions or different rotation speeds.

Detailed Description

The present invention will be described in detail below with reference to several specific exemplary embodiments in conjunction with the contents of the foregoing "background of the invention", "summary of the invention", and "brief description of the drawings".

In particular, the present invention provides a twisting device, as shown in fig. 3 and 5 and with reference to fig. 1 and 2, as well as a twister 0 for twisting and then outputting multiple strands of yarn fed into said twisting device and a support of said twister 0, wherein said "strand" of multiple strands refers to substantially any fiber product of the textile industry, such as sliver, roving, filament, thread, etc., for twisting, said support of the twister being actually used for mounting said twisting device on a twisting machine, said support of said twister comprising, in all the embodiments described in the present description, a support of said rotary twister 1, which is indicated by reference numeral 1013, and a support of said winder 2, which is indicated by reference numeral 2013, as shown in fig. 3 and 5. Unlike the conventional two-for-one twister and ring spinning frame and all the twisting solutions disclosed so far, as shown in fig. 1 to 3 and fig. 5 and 6, the present invention provides a technical feature of the twisting device, firstly, the twister 0 includes a rotary twister 1 which can perform twisting operation on the multi-strand input thereto by rotation, and the multi-strand input to the rotary twister 1 can be wound, and the wound multi-strand can be unwound when the rotary twister 1 rotates and output from the inside of the wound multi-strand after generating a bend. All twisting machines are equipped with the collecting and winding device as described in the background section above, which as described above with reference to figures 3 and 5, performs a continuous drawing action on the strands. With reference to fig. 2 and 7, it is conceivable that the multi-strand wires at the bending point are under tension due to the pulling force of the collecting and winding device and the friction force of the wound multi-strand wires, and the multi-strand wires at the bending point generate a force on the contact surface of the multi-strand wires due to the tension, and the reaction force of the force is exerted on the multi-strand wires to clamp the multi-strand wires, so that the multi-strand wires are pinched by two fingers. The twisted strands can produce twisting effect by continuously rotating the pinched strands with the rotation of the rotary twister 1, and specifically, the twister included in the present invention can continuously twist the strands between the bending point and the collecting and winding device to produce twisted strands with reference numeral 14 as the strands are clamped at the roller of the collecting and winding device; it is in fact possible to produce a twisting effect by pinching two of the strands with two hands and rotating one of the hands. Referring to fig. 7, the bending output of the strands through the inner portion of the winding portion according to the present invention is to prevent the strands output from the rotary twister 1 from interfering with the strands to be wound, and since the strands are bound together from three hundred sixty degrees, the strands are bent and output from the inner portion of the winding portion, so that the interference with the strands around the winding portion can be avoided. The rotary twister 1 is actually the core component of the twister of a twisting device provided by the invention, and the rotary twister can be actually called as the rotary twisting component of the core of the twister. Referring to all the drawings except fig. 4, in order to allow the multi-strand fed into a twisting apparatus provided by the present invention to be wound on the rotary twister 1, in the present invention, the twister 0 further includes a winder 2 for winding the multi-strand fed into the twister 0 on the rotary twister 1, although the rotation of the rotary twister 1 described with reference to fig. 7 may also contribute to winding the multi-strand thereon. Referring to fig. 7, if the yarn on a wound bobbin is unwound and pulled out from the hollow central bobbin 16 to the collecting and winding device, and then the unwound yarn is ensured to be in a proper tight state at the bending position of the head of the central bobbin 16 and the yarn penetrating into the central bobbin 16 is continuously rotated, the twisting effect of the yarn in the central bobbin 16 can be generated, of course, the bobbin formed by the yarn around the central bobbin 16 must be wound for enough tight turns and certain winding strength is ensured to form certain friction resistance, so that the proper pulling of the collecting and winding device can be matched to realize the necessary tight state of the yarn at the bending position, and the yarn can continuously rotate around the central bobbin 16 to realize the twisting principle of the twisting device provided by the invention And the section of the multi-strand between the collecting and winding device is twisted to form a twisted multi-strand 14, and the twisting degree of the multi-strand can be controlled by controlling the autorotation speed of the yarn bobbin and the pulling and collecting speed of the collecting and winding device to the multi-strand. Of course, the example shown in fig. 7 is only a simple example for understanding the technical principle of the present invention, and is not intended to limit the implementation of the present invention, for example, for the present invention, it is necessary to refer to fig. 7 to ensure that the strands can be continuously and continuously wound on the rotary twister, and the implementation manner of winding the strands together in the specific implementation is not necessarily limited to the form of winding into a bobbin as shown in the abstract diagram of fig. 7.

Referring to all the drawings except fig. 4, as a preferred embodiment of the above technical solution of the present invention, the winder 2 is designed and manufactured to preferentially wind the multi-strand wire on the rotary twister 1 by means of rotation. As described above, the friction between the twisted strands wound around the rotary twister 1 and the rotary twister 1 or the friction between the twisted strands together with the collecting and winding device of the twister can make the twisted strands receive pulling force everywhere so as to achieve the effect of tightening the twisted strands when the twisted strands are bent, the tightened twisted strands generate the clamping effect on the twisted strands, and the tightened twisted strands can generate the twisting effect when rotating together with the rotary twister 1. Although a manipulator or some other mechanical mechanism may be used to wind the strands together, the winding of the strands by means of rotation is a simple direct and natural way, and theoretically, the strands can be drawn out from the winder 2 and wound on the rotary twister 1 only if there is a difference in the turning direction and the rotation speed between the winder 2 and the relevant parts of the rotary twister 1, and the mechanism of the corresponding electromechanical design is quite simple and practical.

As a preferred embodiment of the above-described rotary type bobbin according to the present invention, referring to all drawings except fig. 4, the rotary twister 1 is designed and manufactured such that the direction of the axis of rotation thereof is preferentially aligned with the direction of the axis of winding of the strands fed to the rotary twister 1. Referring to all the figures except fig. 4, for the first to third embodiments of the twisting device described in the present specification, it can be seen that the rotary twister 1 can synchronously perform the winding of the multiple strands and the twisting of the multiple strands by its own rotation when the direction of the axis of rotation of the rotary twister 1 coincides with the direction of the axis of the winding of the multiple strands. That is, the axial lead direction of the rotation shaft of the rotary twister is consistent with the axial lead direction of the winding of the multiple strands, which means that the rotary twister 1 can simultaneously and synchronously realize the winding of the multiple strands along the belt when the rotary twisting is carried out on the multiple strands, thus simplifying the twisting process and the electromechanical design structure of the rotary twister 1.

As a typical embodiment of the above-mentioned technical solution of the rotary type bobbin according to the present invention, referring to all the figures except fig. 4, the bobbin 2 may include a conduit 201, and the conduit 201 is configured to guide the strands inputted to the twister 0 to the periphery of the rotary twister 1, that is, the strands inputted to the twister 0 may penetrate the conduit 201 and reach the periphery of the rotary twister 1 through an end opening of the conduit 201. As shown in fig. 2, 3 and 5, the wire guide 201 may rotate around the rotary twister 1 so as to wind the strands output from one end opening of the wire guide 201 on the rotary twister 1. In fact, as long as there is a difference in the direction of rotation or the rotational speed between the conduit 201 and the rotary twister 1, the multi-strand can be drawn out from the conduit 201 and wound on the rotary twister 1, and of course, the rotary twister 1 certainly requires an initialization operation when in use, and referring to fig. 2, 3 and 5, for example, the multi-strand is appropriately wound on the multi-strand winding portion of the rotary twister 1 until a sufficient friction force for relatively stably fixing the multi-strand on the winding portion is generated, and the collection winding device also needs to provide an appropriate drawing force for the multi-strand in the rotary twister 1 when performing the initialization operation of the rotary twister 1.

As a preferred embodiment of the above technical solution of the present invention, as shown in fig. 1, fig. 2, fig. 3, fig. 5 and fig. 6, the conduit 201 is fastened to a hollow rotating shaft 2011, and an inner hollow channel of the conduit 201 is communicated with the hollow interior of the rotating shaft 2011, so that the multiple strands input to the twister 0 can penetrate into the conduit 201 through the hollow interior of the rotating shaft 2011 and then reach the periphery of the rotary twister 1 through an opening at one end of the conduit 201, and the rotating shaft 2011 can rotate continuously to drive the conduit 201 to rotate continuously. Many possibilities for driving the rotation shaft 2011 and the conduit 201 are, for example, a gear transmission, a pulley transmission, etc., and for the first to third embodiments of the twisting apparatus described in this specification, a pulley transmission is used, although a gear transmission and any other transmission are also possible.

Referring to fig. 4 and 7, the rotary twister 1 according to a preferred embodiment of the present invention will comprise a hollow reel 101, and the winder 2 can wind the multiple strands inputted to the twister 0 on the reel 101. The cord reel 101 can be continuously rotated, and the winding of the multi-strand on the cord reel 101 can be achieved by the difference in the rotation direction or the rotation speed between the cord reel 2 and the cord reel 101 in cooperation with the cord reel 2 for rotatably achieving the multi-strand winding as described above. Of course, in the present embodiment, as shown in fig. 2, 3 and 5 and referring to fig. 7, the multiple strands wound on the cord reel 101 may be unwound from the cord reel 101 and be output from the hollow interior of the cord reel 101 after one-fold bending occurs while the cord reel 101 continues to rotate. In this preferred embodiment of the rotary twister 1, the power for unwinding the stranded wires can be from the collecting and winding device, as long as the pulling force of the collecting and winding device on the stranded wires is larger than the friction force between the wound stranded wires and the winding position thereof and the friction force between the wound stranded wires, and the unwound stranded wires will naturally form a bend as long as they are output from the interior of the winder 101, and after all, the winding position of the stranded wires will be located on the outer surface of the winder 101 as shown in fig. 2, 3, 5 and 7, so that this embodiment of the invention is completely feasible and mechanically quite simple and straightforward.

As a preferred embodiment of the above technical solution using the reel, as shown in fig. 1, 2, 3, 5 and 6, the rotary twister 1 includes a hollow rotating shaft 1011, the hollow rotating shaft 1011 is tightly inserted into the hollow interior of the reel 101, and the hollow rotating shaft 1011 can rotate continuously to drive the reel 101 to rotate continuously. Therefore, in this embodiment, the winder 101 can rotate continuously as long as the hollow rotating shaft 1011 is driven to rotate continuously, and the routing channel formed in the hollow portion of the hollow rotating shaft 1011 can provide a path for outputting multiple strands.

In addition, when the technical solution of the cord reel is adopted, referring to all the drawings of the specification except fig. 4, a typical embodiment is that the external shape of the cord reel 101 is to be a taper shape, in this embodiment, as shown in fig. 2, fig. 3, fig. 5 and fig. 7, the multi-strand wound on the cord reel 101 via the winder 2 is firstly wound on one end of the taper shape near to the large diameter thereof, and the multi-strand wound on the cord reel 101 is unwound and can be bent into the opening of one end of the taper shape near to the small diameter thereof and output from the opening of one end of the taper shape near to the large diameter thereof through the hollow interior of the entire cord reel 101. The reason why the reel 101 is preferably made to have a tapered shape is to facilitate unwinding of the strands and to prevent the strands tightly wound together from being broken by the collecting and winding device due to over-tightening of the winding, because the strands are wound on the reel 101 from the end of the tapered shape of the reel 101 near the large diameter, the strands wound on the reel 101 under the pulling action of an external force will slip and unwind toward the end of the tapered shape with the small diameter, and will slip smoothly from the end of the large diameter toward the end of the small diameter, and it is needless to say that the twisting device of the present invention requires a few turns of the strands slightly more at the end of the tapered shape with the large diameter to generate enough friction force to prevent the strands from being easily unwound from the reel 101.

For a preferred embodiment of the above-mentioned solution of the present invention using a conduit, referring to all the figures except fig. 4, 6 and 7, the conduit 201 is preferably designed and manufactured in a U shape with central symmetry, which helps to keep the position of the conduit 201 balanced during high-speed rotation and prevent the guide conduit 201 from being unnecessarily thrown off at its installation position.

Finally, as shown in fig. 3 and 5 and referring to fig. 2 and 7, the present invention also provides a twisting machine, which comprises a frame 4 and the twisting device for twisting multiple strands, as described above, so that the twisting machine using the twisting device can conveniently integrate the doubling process and the twisting process or the spinning process and the winding process into a single process.

Note that the above-described embodiments are not intended to limit the embodiments of the present invention, and there are certainly many possible implementations and various optimizations and improvements of the present invention, such as providing a ring-shaped recess on the reel 101 to allow the stranded wire 13 to be stably wound thereon without being easily unwound; or a hollow rotating shaft which can be driven to rotate independently and accurately control the steering rotating speed is inserted into the hollow rotating shaft 1011, so that the twisted multi-strand 14 penetrating into the hollow rotating shaft 1011 passes through the hollow rotating shaft to enhance the twisting effect; or as mentioned above, various sensors are added to monitor the winding number of the stranded wire on the winder 101, and the speed of winding, pulling, collecting and twisting the stranded wire 14 of the stranded wire collecting and winding device and the rotation direction and speed of the winder 2 and the rotary twister 1 are dynamically controlled according to the parameters of the sensors, for example, any modification, replacement, conventional improvement and the like made within the technical principle of the present invention are included in the scope of intellectual property protection of the patentee claimed in the claims of the present invention as long as the technical principle of the present invention is based on.
