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) adopting the Twisting device.

Background

The textile industry usually needs to twist raw material yarns before spinning by using yarns, wherein the twisting is to wind and twist two or more raw material wires into a strand, and the two or more raw material wires can be from a plurality of raw material bobbins or from a multi-strand combined by a plurality of raw material wires. In spinning, a plurality of strands of material, such as sliver, strand, yarn, thread, or thread, are twisted or axially wrapped about their axes to "twist" or wrap the strands of material. 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 collection winding device which actively draws, collects and winds the twisted multi-strand wires output from the twisting device after being twisted into a finished twisted multi-strand wire barrel, wherein the collection 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 oppositely, and the rollers are usually called "winding rollers" in the textile industry. Whether the collecting and winding device is a single roller or a pair of counter-rotating rollers or even any other type of arrangement, the strands fed to virtually all twisting machines, represented by two-for-one twisting machines, are subjected to a continuous pulling action by the collecting and winding device. When the collecting and winding device adopts the arrangement of the single roller, the finished product twisting multi-strand bobbin can continuously rotate along with the single roller, so that the twisting multi-strand which is twisted and output by the twisting device is continuously drawn out and wound into the final finished product twisting 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 tightly clamped by the two rollers, and is continuously pulled out of the twisting device and then is wound into the 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 needs two working procedures in practical production, and for the two-for-one twister, besides the twisting working procedure of the two-for-one twister, a doubling working procedure of combining the multiple strands needing to be twisted into one parallel multiple strand and winding the parallel multiple strand into a parallel multiple strand bobbin must be carried out before the twisting working procedure; 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 twisting device provided by the invention is the same as the twisting technical scheme disclosed at present, and is also used for carrying out rotary twisting operation on the multi-strand input into the twisting device so as to twist the multi-strand input into the twisting device, and the multi-strand subjected to rotary twisting operation by the twisting device can be output from the twisting device. The twisting device provided by the invention is different from the twisting technical scheme disclosed at present firstly in that: the twisting device performs a first twisting operation on the multi-strand input into the twisting device in a manner of clamping and rotating the multi-strand composed of a plurality of raw material wires input into the twisting device to form a twisted multi-strand generating a twist, the twisting device also winds and collects the twisted multi-strand input into the twisting device and generated after the first twisting operation is performed in a rotating winding manner, the twisted multi-strand wound and collected at one position in the rotating winding manner forms a hollow through rotating body, the twisted multi-strand wound and collected on the rotating body can be unwound from the rotating body and output to the outside of the rotating body from the hollow through part of the rotating body, the twisted multi-strand output to the outside of the rotating body is subjected to a second twisting operation by the twisting device in a manner of clamping and rotating the twisted multi-strand again, the second twisting operation is consistent with the twisting direction of the twist generated by the first twisting operation. The twisting direction of the twist generated by the two twisting operations is consistent, so that the raw multi-strand can generally meet the twisting degree requirement of commercial twisting multi-strand through at least two twisting operations, and the invention does not exclude the arrangement of third or even more twisting operations and the rotating bodies between the subsequent twisting operations in the provided twisting device, and only needs the consistent twisting direction of the twist generated by all twisting operations. In order to effectively execute the first twisting operation and the second twisting operation, the twisting device provided by the invention comprises a first twister for implementing the first twisting operation on the multi-strand input into the twisting device and a second twister for implementing the second twisting operation on the twisted multi-strand. The reason why the second-pass twister is provided to perform the second-pass twisting operation is that, in addition to the aforementioned enhancement of the twisting effect on the multiple-strand wires fed to the twisting device, the inventors found in practice that when the multiple-strand wires are unwound from the rotary body by being twisted, the already generated untwisting occurs due to the direction of the rotary unwinding, thereby impairing the twisting effect of the first-pass twisting operation, so that the addition of the second-pass twisting operation in which the direction of twist of the generated twist is the same as the direction of twist of the first-pass twisting operation in the twisting device can at least cancel the untwisting that occurs when the multiple-strand wires are unwound from the rotary body.

As an alternative embodiment of the above technical solution, the twisting device comprises a first twister which clamps the multiple strands of the input twisting device in a direct clamping manner and rotates the multiple strands to perform the first twisting operation. The direct clamping means that the multi-strand fed to the twisting device is tightly clamped after the two pieces are folded, and it is obvious that twisting can be applied to the multi-strand by rotating the multi-strand while clamping the multi-strand, thereby generating a twist.

In a preferred implementation of the above alternative embodiment, the first twister directly clamps the multiple strands fed into the twisting device by using a roller made of elastic material and rotates the multiple strands to perform the first twisting operation. The advantage of using a resilient material is that the articles that clamp the strands are in full contact to ensure a clamping effect.

As another alternative embodiment of the above technical solution, the twisting device includes the first twister to bend the multiple strands applied with traction force and input into the twisting device to achieve the clamping effect on the multiple strands and rotate the multiple strands to implement the first twisting operation. As described above, almost all types of twisting machines include a "collecting and winding device" that actively draws and collects twisted strands that are twisted and output from a twisting device and then winds the twisted strands into a final finished twisted multi-strand bobbin, so that the strands that are input to the twisting device and the twisted strands that are generated during twisting are actually always in a drawn state, and thus axial tension exists everywhere, and the reaction force of the resultant force of the axial tension at both sides of the bent portion after the bending of the multi-strand or twisted multi-strand can radially act on the multi-strand or twisted multi-strand, thereby achieving the clamping effect required by the rotational twisting.

As an alternative implementation manner of the above embodiment of directly clamping multiple strands, the first twister will include a hollow through hollow rotating shaft for multiple strands input into the twisting device to pass through, the multiple strands pass through the hollow interior of the hollow rotating shaft from one end opening of the hollow rotating shaft and pass out from the other end opening of the hollow rotating shaft, the first twister further includes a pair of elastic rubber rollers tightly attached to the hollow rotating shaft, and the multiple strands passing through the hollow rotating shaft will be tightly clamped by the pair of rubber rollers and rotate together with the hollow rotating shaft and the rubber rollers so as to implement the first twisting operation on the multiple strands and generate the twisted multiple strands. In this implementation, when the hollow rotating shaft I drives the pair of rubber rollers to start rotating, the multi-strand wires penetrating through the hollow rotating shaft I are actually subjected to rotary twisting, so that the multi-strand wires are twisted into twisted multi-strand wires. A pair of rubber rollers is adopted to directly clamp the stranded wires, so that the stranded wires can be fully clamped by the elasticity of rubber, and the twisted stranded wires generated after the rotary twisting can freely roll without being prevented from leaving the rubber rollers and then being collected on a subsequent rotating body. The first twister also comprises a rotating bracket which is fastened with the first hollow rotating shaft into a whole, the rotating bracket is used for guiding twisted multi-strand wires to the rotating body in the invention, and in specific implementation, the rotating bracket can be additionally provided with a guide pipe for the twisted multi-strand wires to penetrate through or a pulley and other mechanisms for guiding the twisted multi-strand wires to travel. The twisting device further comprises a second hollow rotating shaft and a hollow through winding reel sleeved on the second hollow rotating shaft in a fastening mode, the twisted multi-strand wires generated by the first twister can be tightly wound on the winding reel through the rotating support, the second hollow rotating shaft and the winding reel sleeved on the second hollow rotating shaft in the fastening mode can be matched with the first hollow rotating shaft and the rotating support to rotate, and the rotating speed between the rotating support and the winding reel is different, so that the twisted multi-strand wires leaving the rotating support are wound and collected on the winding reel in a rotating winding mode to form a hollow through rotating body. The twisted multi-strand wires collected on the winding reel can be unwound from the winding reel and continuously drawn and output from the winding reel and the hollow through inner part of the hollow rotating shaft II to the outside of the first twister, and the twisted multi-strand wires are unwound from the rotating body and output from the hollow through inner part of the rotating body, and the power of continuous drawing is derived from the collecting and winding device commonly equipped in the twisting machine. In this implementation, the twisted multi-strand wires collected on the rotating body must be tightly wound on the bobbin, so as to ensure that the rotation speed difference between the bobbin and the rotating bracket can form enough traction force to make the twisted multi-strand wires continuously drawn and wound on the bobbin to form the rotating body. Specifically, when the rotation speed of the rotating bracket is greater than that of the winding reel and the rotation directions of the rotating bracket and the winding reel are consistent, twisted multi-strand is actively wound on the winding reel by the rotating bracket, and when the rotation speed of the same rotation direction of the winding reel is greater than that of the rotating bracket, the twisted multi-strand is mainly continuously pulled by the winding reel and wound on the winding reel. In specific implementation, when the first twister is initialized, an operator needs to manually rotate the hollow rotating shaft to drive the pair of rubber rollers to rotate so as to carry out rotary twisting on the multiple strands, and then manually pulls the twisted multiple strands to tightly wind the multiple strands on the winding reel for multiple circles to form a rotating body which is tightly wound, so that the first twister can be ensured to smoothly carry out the first twisting operation after the twisting device is started, and the twisted multiple strands are output to the second twister. In this implementation manner, the twisted multi-strand output to the outside of the first twister is subjected to the second twisting operation performed by the second twister, and the second twisting operation provided in the present invention can further perform rotary twisting on the twisted multi-strand to enhance and ensure the twisting degree of the final product, and can also counteract the possible back-off of the twisted multi-strand when the twisted multi-strand is unwound from the rotating body, because the twist direction of the twist generated by the second twisting operation is the same as the twist direction generated by the first twisting operation.

As an optional implementation manner of the above-mentioned implementation manner for implementing the clamping effect required by the rotational twisting of the multiple strands by bending the multiple strands subjected to the traction force, the first twister may include a hollow through first hollow rotating shaft for the multiple strands input into the twisting device to penetrate, the multiple strands penetrate through the first hollow rotating shaft and then are bent to penetrate into a winding conduit fastened with the first hollow rotating shaft, if the multiple strands are clamped at the bent position, the first hollow rotating shaft and the winding conduit may rotate to implement the first twisting operation on the multiple strands, so that the first twister of this implementation manner introduces the multiple strands into the first twister by means of the first hollow rotating shaft and the winding conduit and bends the multiple strands and twists the multiple strands through rotation, and in fact, the multiple strands introduced into the first hollow rotating shaft before the multiple strands are bent position rotate together with the winding conduit Then, the rotary twisting is performed to generate the twist as twisted strands. The twisting device provided by the implementation mode further comprises a second hollow rotating shaft which is through in a hollow mode and a bobbin which is through in the hollow mode and is sleeved on the second hollow rotating shaft in a fastening mode, the multiple strands penetrating through the first hollow rotating shaft and the winding guide pipe are subjected to the first twisting operation and then become twisted multiple strands and are output from an opening at one end of the winding guide pipe, the twisted multiple strands output from the opening at one end of the winding guide pipe can be tightly wound on the bobbin, the second hollow rotating shaft and the bobbin which is sleeved on the second hollow rotating shaft in the fastening mode can rotate in a matching mode with the first hollow rotating shaft and the winding guide pipe, and the difference exists between the rotating speed of the winding guide pipe and the bobbin, so that the twisted multiple strands output from the opening at one end of the winding guide pipe are wound and collected on the bobbin in a rotating winding mode to form a rotating body which is through in the hollow mode. Similarly to the previous embodiment, in the present embodiment, the twisted multi-strand wound on the bobbin can be unwound from the bobbin and continuously drawn out of the hollow through interior of the bobbin and the second hollow rotating shaft to the outside of the first twister, and the force of the continuous drawing is also from the collecting winding device equipped in the previous twister, and the twisted multi-strand outputted to the outside of the first twister will receive the second twisting operation performed by the second twister.

As another optional implementation manner of the above implementation manner that the clamping effect required by the rotational twisting of the multiple strands is achieved by bending the multiple strands subjected to the traction force, the first twister includes a hollow through first hollow rotating shaft and a twisting rotary table fastened with the first hollow rotating shaft into a whole, and a rotating axis of the twisting rotary table coincides with a rotating axis of the first hollow rotating shaft, so that the first hollow rotating shaft can drive the twisting rotary table to continuously rotate after being driven to rotate by a motor. The twisting device in the implementation mode further comprises a hollow through second hollow rotating shaft and a hollow through winding drum sleeved on the second hollow rotating shaft in a fastening mode, so that the second hollow rotating shaft can drive the winding drum to rotate continuously, the second hollow rotating shaft is inserted into the hollow of the first hollow rotating shaft, and the winding drum is located in the center of the interior of the twisting turntable. The first hollow rotating shaft in the implementation mode actually plays a role of driving the twisting turntable to rotate, the twisted multi-strand wires input into the twisting device are rotated and twisted after the edges of the twisting turntable are bent, and are tightly wound on the winding cylinder, and the multi-strand wires input into the twisting device are rotated and twisted to form twisted multi-strand wires, namely the multi-strand wires input into the twisting device before the twisting edges of the twisting turntable rotate when the twisting turntable rotates This results in a twisted strand to which a twist is applied. The second hollow rotating shaft and the winding drum sleeved on the second hollow rotating shaft in a fastening mode can be matched with the first hollow rotating shaft and the twisting rotary table to rotate, and the difference exists between the rotating speeds of the twisting rotary table and the winding drum, so that the twisted multi-strand wires which are bent towards the inner center of the twisting rotary table through the edge of the twisting rotary table can be wound and collected on the winding drum in a rotating winding mode, and a hollow through rotating body is formed. Similarly to the two previous implementations, in the present implementation, the twisted multi-strand wound around the winding drum can be unwound from the winding drum and continuously drawn out of the first twister from the winding drum and the hollow through interior of the second hollow rotating shaft, and the continuously drawn drawing power is also from the collecting winding device of the twisted multi-strand of the twister equipped with the twisting device, and then the twisted multi-strand outputted out of the first twister is subjected to the second twisting operation by the second twister.

As an alternative to the above-described embodiment in which the desired clamping effect for the rotational twisting of the strands is achieved by bending the strands subjected to a pulling force, the obvious difference existing with the three realization modes is that the first twisting device included in the twisting device can be a ring spinning twisting component, specifically, the first twisting device includes a hollow through hollow rotating quill, the hollow rotating quill is inserted in the inner center of a ring-shaped steel collar, the ring has an I-shaped cross section and is also provided with a steel wire ring in a clamping way, the steel wire ring is provided with a notch, the elasticity of the steel wire ring can ensure that the steel wire ring can be clamped on the ring through elastically expanding the notch so as not to slip off the ring, and the steel wire ring clamped on the ring can freely slide around the ring-shaped ring. The multi-strand yarn inputted into the twisting device penetrates the traveler and is bent toward the inner center of the ring-shaped ring via the traveler and then is tightly wound on the hollow rotating quill. The first twister also comprises a roller mechanism which can tightly clamp the multiple strands and input the multiple strands into the twisting device, and the roller mechanism tightly clamps the multiple strands by using a roller and controls the conveying speed of the multiple strands conveyed to the first twister for rotating and twisting operations by using the rotating speed of the roller. The hollow rotating quill comprised by the first twister can continuously rotate to drive the stranded wires bent by the steel wire ring to continuously rotate around the stranded wire output port of the roller mechanism, so that the first twisting operation is realized and the twisted stranded wires are generated. The multi-strand wires can generate axial tension after being pulled by the hollow rotating quill, so that the multi-strand wires can be clamped at the bending part of the steel wire ring, and the multi-strand wires bent by the steel wire ring can rotate together with the steel wire ring at a high speed due to being pulled by the hollow rotating quill, so that the multi-strand wires input into the first twister of the implementation mode actually positioned between the roller mechanism and the steel wire ring become twisted multi-strand wires which are twisted for implementing rotating twisting to generate twisting. In this implementation manner, the twisted multi-strand wires are bent towards the center inside the ring via the traveler and then tightly wound on the hollow rotating quill, and the hollow rotating quill continuously pulls the twisted multi-strand wires in a rotating winding manner and winds and collects the twisted multi-strand wires on the hollow rotating quill to form the hollow through rotating body. In fact, the rotary twisting method of this implementation is completely the same as the conventional ring spinning twisting assembly of the ring spinning frame, and the implementation differs from the conventional ring spinning twisting assembly only in that the twisted multi-strand yarn wound and collected on the hollow rotary quill can be unwound from the hollow rotary quill and continuously drawn out of the first twister from the rotating body and the hollow through interior of the hollow rotary quill, and then the twisted multi-strand yarn output out of the first twister can receive the second twisting operation performed by the second twister. The quill of a conventional ring spinning twisting assembly is generally not hollow and does not allow the twisted multi-strand yarn on the quill to be unwound therefrom and output from the hollow interior thereof. For the twisting device provided by the invention, the second twister can adopt all the above-mentioned modes of implementation or any other type of clamping and then rotating twisting mode.

As an optional implementation of the technical solution of the present invention, the second-pass twister included in the twisting device may implement the second-pass twisting operation by bending the twisted multi-strands subjected to the pulling force to achieve the clamping effect on the twisted multi-strands and rotating the twisted multi-strands.

The invention also provides a twisting machine, which comprises a twisting device for twisting and outputting a plurality of strands of raw material wires and a rack for mounting the twisting device.

In summary, according to the twisting device and the twisting machine using the twisting device provided by the invention, at least two twisting operations with consistent twisting direction are continuously carried out on the multi-strand yarn composed of multiple raw material threads, and the twisting multi-strand yarn generated by twisting is collected and wound by matching with a winding device, so that two processes required by the traditional two-for-one twisting machine and the ring spinning frame can be conveniently integrated into one twisting machine to be completed at one time, the production targets of two separate processes of the traditional two-for-one twisting machine and the ring spinning frame are realized by successfully using a single twisting machine to be further in place, the field is saved, and the consumption of power energy and the corresponding labor cost are also saved.

Fig. 2 is a schematic view of the appearance and structure of the first pass twister and associated parts for producing the rotating body of the first embodiment of the twisting apparatus of the present invention. Fig. 2 is divided into four sub-views from left to right, separated by three vertical lines, with parenthesis in the lower left corner of each view and arabic numerals therein numbering each view. The (1) and (2) sub-views show the cross-sectional schematic views of the first twister 1 and the relevant parts required for producing the rotating body 3, and the (3) and (4) sub-views show the appearances of the first twister 1 and the parts required for producing the rotating body 3. The (2) and (4) sub-views also show how the raw material wire 7 is twisted by a first twist to generate a twisted multi-strand wire 8, how the twisted multi-strand wire 8 is rotated and wound to generate the hollow through rotating body 3, and also show that the twisted multi-strand wire 8 is unwound from the rotating body 3 and output to a second twister. As can be seen from fig. 2, the hollow shaft 102 of the first twister and the hollow shaft 104 of the second twister for forming the rotating body 3 are respectively provided with a driving wheel structure 1023, and the driving belt 10 driven by the motor 9 as shown in fig. 2 and referring to fig. 1 can drive the hollow shaft 102 of the first twister and the hollow shaft 104 of the second twister forming the rotating body 3 to rotate continuously by driving the two driving wheels 1023 to rotate. In the first embodiment, a pair of said rubber rollers 100 as shown in fig. 2 and 1 are mounted on a hollow sleeve 1001, the hollow sleeve 1001 is tightly sleeved at the opening of the first hollow rotating shaft 102, the rotating bracket 101 is fastened on the hollow sleeve 1001 and rotates synchronously with the hollow rotating shaft 102 and the rubber roller 100, the twisted multi-strand 8 is generated after the multi-strand introduced into the hollow rotating shaft 102 is tightly clamped and rotated by the pair of rubber rollers 100, the twisted multi-strand 8 leaves the rubber roller 100 and is wound on the winding reel 103 through two pulleys 1012 on the rotating bracket 101, in order to ensure a tight winding of the twisted strands 8 on the bobbin 103, as shown in figure 2, the first embodiment also provides above the rotating bracket 101 a conical roller 1013 driven by a torsion spring 1011, the side profile of said tapered roller 1013 follows the inverted conical profile of the core component spool 103 forming the rotary body 3. The straight arrow on the transmission belt 10 in fig. 2 represents the traveling direction of the transmission belt 10, and as shown in fig. 1 and fig. 2, it can be seen that the rotation direction of the rotating bracket 101 of the first twister 1 is consistent with the rotation direction of the hollow rotating shaft number two 102 and the winding reel 103 of the generating rotating body 3, only because the rotating speed of the rotating bracket 101 is different from that of the winding reel 103, and the twisted multi-strand 8 is tightly wound on the winding reel 103, the winding reel 103 and the rotating bracket 101 can continuously pull out the twisted multi-strand 8 from the pair of rubber rollers 100 and even the first twister 1 to wind and collect the twisted multi-strand 8 on the winding reel 103 to form the rotating body 3. As shown in fig. 2 and fig. 1, since the hollow rotating shaft 104 and the winding reel 103 are both hollow and through, the twisted multi-strand 8 tightly wound on the winding reel 103 naturally forms a hollow and through rotating body 3, and the twisted multi-strand 8 wound and collected on the rotating body 3 is pulled continuously by the collecting and winding device provided in the twisting machine, unwound from the rotating body 3 and pulled out from the hollow interior of the winding reel 103 and the hollow interior of the hollow rotating shaft 104 inside the rotating body 3 to the second twister 2.

Fig. 3 is composed of left and right sub-views separated by a vertical line, the two sub-views being numbered as (1) th and (2) th sub-views with parenthesis and numerals below, respectively, as shown in fig. 3 and referring to fig. 1 the (1) th sub-view of fig. 3 shows the appearance of the second-pass twister 2 and the (2) th sub-view shows a schematic cross-sectional view of the second-pass twister 2. The second twister as shown in fig. 3 and described with reference to fig. 1 is designed to bend the twisted multi-strands 8 which are continuously subjected to traction to achieve a gripping effect on the twisted multi-strands 8 in cooperation with the continuous rotation to perform a rotary twisting operation. As shown in fig. 3 and referring to fig. 1, in the first embodiment, the second twister 2 includes a hollow through hollow conduit 203 for passing the twisted multi-strand wires 8, a hollow shaft 202 is sleeved outside the hollow conduit 203, the hollow shaft 202 has a driving wheel 205 structure capable of being driven by the corresponding motor 9 and driving belt 10 to rotate continuously, the hollow shaft 202 and the hollow conduit 203 are engaged by a ball bearing so that the hollow shaft 203 can rotate continuously at a high speed to complete the second twisting operation, and the hollow conduit 203 and the hollow shaft 202 are both tightly mounted on the frame 6 of the first embodiment through the corresponding bracket 13. As shown in fig. 3 and referring to fig. 1, a hollow rotating disc 201 is tightly sleeved at an opening of a hollow rotating shaft 202, the twisted multi-strand 8 unwound from the rotating body 3 passes through a hollow guide tube 203 and then is output to the collecting and winding device equipped in the first embodiment through edge bending of the rotating disc 201, as shown in the enlarged right area of the (2) th sub-view of fig. 3, the twisted multi-strand 8 is clamped at the edge bending of the rotating disc 201 due to continuous pulling force of the collecting and winding device, and as the hollow rotating shaft 202 is driven to rotate by the driving belt 10 through the driving wheel 205, the rotating disc 201 also continuously rotates around the collecting ring 12 located below the collecting and winding device as shown in fig. 1 with the clamped twisted multi-strand 8, thereby completing the implementation of the second twisting operation. The edge of the rotating disc 201 of the second-pass twister 2 of the first embodiment shown in fig. 3 is provided with a friction-reducing porcelain ring 204 for allowing twisted multi-strand wires to pass out from the edge of the rotating disc 201 and to bend, so as to highlight the effective rotating twisting position 3 between the second-pass twister 2 from the porcelain ring 204 to the following wire collecting ring 12, in the (2) view of the twisting position diagram 3, the twisted multi-strand wires 8 positioned inside the hollow guide 203 do not draw a spiral twist, but draw a spiral twist only on the twisted multi-strand wires 8 output from the porcelain ring 204.

Fig. 4 is a schematic view showing the appearance and structure of a twisting machine using a second embodiment of the twisting device of the present invention. All the straight arrows in this figure next to the feed line 7 and the twisted strands 8 are, like in figure 1, also representative of the direction in which the feed line 7 and the twisted strands 8 are drawn, the straight arrows in each belt 10 are, like in figure 1, also representative of the direction in which each belt 10 is run, as shown in fig. 4 and referring to fig. 3, five pairs of arc-shaped arrows from bottom to top in fig. 4 respectively indicate the rotating directions of the first hollow rotating shaft 112 of the first twister 1, the winding guide 111, the second hollow rotating shaft 114 for generating the rotating body 3, and the bobbin 113, the hollow rotating shaft 202 of the second twister 2, and the turntable 201 on which the rotary bodies are tightly fitted, it can be seen from fig. 4 that the turning directions of the relevant parts of the first twister 1 and the generating rotating body 3 are identical, the difference in rotational speed between the two can generate a pulling force to wind the twisted multi-strand wire 8 on the bobbin 113 to form the rotator 3 as in the first embodiment. As shown in fig. 4 and with reference to fig. 5, the second embodiment differs from the first embodiment only in that the first-pass twister 1 is different, and both use the same kind of second-pass twister as it is. The first twister of the second embodiment introduces the multiple strands formed by combining the raw material wires 7 into the first hollow rotating shaft 112 and the winding guide pipe 111, and then the multiple strands are bent once to generate the clamping effect required by rotary twisting at the bent position, and the multiple strands input into the first twister are twisted to generate the twisted multiple strands 8 as the first hollow rotating shaft 112 and the winding guide pipe 111 are driven by the corresponding driving belt 10 to rotate continuously. Due to the absence of the conical roller driven by the torsion spring of the first embodiment, the twisting apparatus of the second embodiment requires the twisted multi-strand 8 to be tightly wound on the bobbin 113 by hand at the start-up initialization to ensure that the rotating body 3 can form and maintain the continuous pulling force on the multi-strand fed to the first twister 1 after start-up. The second embodiment uses the same second-pass twister as the first embodiment but it should be noted that the kind of the second-pass twister 2 is not limited to the present invention, and it is possible to use the same twister as the first-pass twister in practice.

Fig. 5 is a schematic view of the appearance and structure of the first pass twister and associated parts for producing the rotating body of the second embodiment of the twisting apparatus of the present invention. This fig. 5 is composed of two sub-views (1) and (2) separated by a vertical line in the figure, the (1) sub-view showing the appearance of the first-pass twister of the second embodiment and the (2) sub-view showing the cross section of the first-pass twister. As shown in fig. 5 and with reference to fig. 4, the first hollow shaft 112 of the first twister 1 and the second hollow shaft 114 required for generating the rotary body 3 are mounted on the frame 6 of the second embodiment by means of respective brackets 13, and the first hollow shaft 112 and the second hollow shaft 114 also have a structure of a driving wheel 1123 cooperating with the respective driving belt 10. Two pairs of arc-shaped arrows in the (2) th sub-view indicate the same turning directions of the first hollow rotating shaft 112 and the second hollow rotating shaft 114, respectively, and the arc-shaped arrow located below the core part bobbin 113 of the generating rotating body 3 also indicates the same turning directions of the bobbin 113 and the winding guide 111 of the first twister 1.

Fig. 6 is a schematic view showing the appearance and structure of a twisting machine using a third embodiment of the twisting device of the present invention. As shown in fig. 6 and referring to fig. 1 and 4, the third embodiment and the two previous embodiments both use the same second-pass twister 2, but the second-pass twister is optional for the present invention, and the twisting direction of the second-pass twister is only required to be consistent with that of the first-pass twister 1. Different from the above two implementation manners of introducing the two strands formed by annularly combining the raw material wires through the hollow rotating shaft into the first twister, the third embodiment directly introduces the strands to the edge of the twisting turntable 121 to be bent and then tightly winds the strands on the winding drum 123 inside the twisting turntable 121 to form the rotating body 3 as shown in fig. 6; another difference from the two previous embodiments is that it can be seen that the components required for the rotation body generation of the third embodiment are actually integrated in the first-pass twister 1 rather than being located outside the first-pass twister 1 as in the two previous embodiments. The twisting dial 121 of the third embodiment is driven by the first hollow rotating shaft 122 to rotate continuously, so that the multi-strand wires combined by the raw material wires 7, which are input to the twisting device 0 through the lower concentrated ring 12 in fig. 6, are twisted into twisted multi-strand wires 8. As shown in fig. 6 and referring to fig. 7, the core component of the third embodiment driving the forming rotator 3 is a bobbin 123, the bobbin 123 is driven by a second hollow rotating shaft 124, unlike the previous two embodiments, the second hollow rotating shaft 124 of the forming rotator 3 of the third embodiment is inserted into the first hollow rotating shaft 122, a ball bearing is installed between the two hollow rotating shafts of the third embodiment, so that the rotation direction and the rotation speed of the twisting turntable 121 of the first twister 1 and the core component bobbin 123 forming the rotator 3 can be precisely adjusted respectively, so that a certain difference of rotation speed is maintained between the twisting turntable 121 and the bobbin 123, so as to draw and tightly wind the twisted multi-strand from the edge of the twisting turntable onto the bobbin 123, of course, at the time of the initialization of the power-on of the third embodiment, an operator is required to manually rotate the twisting turntable 121 to twist the multi-strand and manually tightly wind the multi-strand onto the bobbin 123 to form the bobbin 123 The rotating body 3 pulls the twisted multi-strand wires 8 to unwind from the rotating body 3, and the unwound multi-strand wires are led to the second twister 2 from the lower part through the hollow through part of the winding drum 123 and the second hollow rotating shaft 124, then pulls the twisted multi-strand wires 8 manually to form tight winding on the finished twisted multi-strand bobbin 5, and then starts the twisting machine of the third embodiment to pull the raw material bobbin 4 continuously to synthesize the multi-strand wires 7 and twist the multi-strand wires into the finished twisted multi-strand bobbin 5 through the twisting device 0, and the initialization operation of the twisting machines of the two embodiments is similar to that of the two embodiments. All of the objects indicated by the unidirectional straight arrows, the arc-shaped arrows and the bidirectional straight arrows in fig. 6 and their meanings are consistent with the corresponding arrows of fig. 1 and 4. As shown in fig. 6 and referring to fig. 7, unlike the two previous embodiments, the first twister 1 and the components required for the generation of the rotating body of the third embodiment are mounted on the frame 6 of the twisting machine by only one bracket 13. Note that the third embodiment can also be completely equipped with the tapered roller of the first embodiment to facilitate the formation of the tightly wound rotating body 3, only by installing the corresponding torsion spring and tapered roller on the opposite side of the multi-strand bend on the edge of the twisting turntable 121. It is also possible to install a torsion spring and a tapered roller on the winding pipe opposite to the outlet of the winding pipe 111 for twisting the multiple strands 8 as actually shown in fig. 4 and with reference to the second embodiment of fig. 1.

Fig. 7 is an external view and a structural schematic view of a first twister and related parts for producing a rotating body of a third embodiment of a twisting device of the present invention. As shown in fig. 7 and referring to fig. 6, the hollow rotating shaft 122 for driving the first twister to rotate and twist and the hollow rotating shaft 123 for driving the second twister to form the rotating body 3 are provided with driving wheels 1223 respectively, which are filled with gray in this fig. 7. It can also be seen from this fig. 7 that, firstly, the ceramic rings 1212 are also installed at the multi-strand bent positions along the edge of the twisting turntable 121 of the third embodiment as in the aforementioned second twister using ceramic rings to reduce the friction force, secondly, the first and second hollow rotating shafts are actually sleeved on a hollow conduit 125, it is noted that this hollow conduit 125 is not essential for the third embodiment, and the hollow conduit 125 which is matched with the second hollow conduit 124 by a ball bearing is used in the third embodiment to reduce the rotation resistance of the second hollow rotating shaft 124. As shown in fig. 1, fig. 2, fig. 4, fig. 5, fig. 6 and fig. 7, the bobbin 103 in the first embodiment, the bobbin 113 in the second embodiment and the bobbin 123 in the third embodiment all play the same role in the respective twisting devices, and the twisted multi-strand 8 output by the first twister is tightly wound thereon to form the intermediate transmission medium between the two twisting operations, and the reverse tapered profiles are adopted for the three to facilitate the easy unwinding of the twisted multi-strand 8 from the rotating body 3.

Fig. 8 is a schematic view showing the appearance and structure of a twisting machine using a fourth embodiment of the twisting device of the present invention. The fourth embodiment uses the same second-pass twister as the three previous embodiments, and differs from the three previous embodiments only in the first-pass twister. As shown in fig. 8 and referring to fig. 10, the fourth embodiment actually employs a ring spinning twisting assembly as the first twister 1, the raw material wires 7 from two raw material wire barrels 4 are combined into a multi-strand wire through the wire collecting ring 12, then tightly held by a pair of rollers and output upward through the pair of rollers 14 at a precise speed, and the single-line bent arrow on the roller 14 indicates the direction in which the roller 14 is actively rotated. The core component of the ring spinning twisting assembly is a hollow rotating quill 1313 inserted in a ring-shaped ring 1311, the multi-strand wires actively output upwards by the roller 14 are bent by a steel wire ring 1312 clamped on the ring 1311 and then tightly wound on the hollow through hollow rotating quill 1313 to form a rotating body 3, and the hollow rotating quill 1313 is driven by a corresponding motor 9 and a driving belt 10 to rotate at a high speed so as to drive the multi-strand wires to continuously rotate around a multi-strand wire output port of the roller 14, so that the first twisting operation is completed. The twisting principle is the same as that of the ring spinning frame which is commonly used at present, and the first twisting unit 1 in the fourth embodiment is different from the general ring spinning frame in that a hollow quill, namely, a hollow rotating quill which is denoted by reference numeral 1313, is used. In fact, after the fourth embodiment is started, the multi-strand located between the drum 14 and the traveler 1312 is twisted into the twisted multi-strand 8, and the hollow through part of the hollow rotating quill 1313 facilitates the hollow through part of the rotating body 3 so that the twisted multi-strand 8 tightly wound on the hollow rotating quill 1313 can be output from the hollow through inside thereof to the second twister 2. as with the previous three embodiments, it is also necessary to initiate the fourth embodiment by manually rotating the traveler to form the twisted multi-strand 8 and tightly wind it on the hollow rotating quill 1313, so that the continuously rotating hollow rotating quill 1312 can continuously apply a pulling force to the multi-strand or twisted multi-strand 8 from the traveler 1312 to form a clamping force at the bending part of the traveler necessary for the rotational twisting. The various types of arrows in this fig. 8 indicate the same objects and meanings as the corresponding types of arrows in all the drawings of the foregoing specification. In addition, although fig. 8 illustrates the fourth embodiment in which the raw material thread 7 from two raw material bobbins is twisted by rotation to form the final product twisted multi-thread bobbin, the fourth embodiment can also twist the roving from a single roving bobbin yarn, that is, a single roving combined by a plurality of yarns as raw material threads, by rotation to form a single spun bobbin yarn product by the twisting device 0 as shown in the figure.

Fig. 9 is an external view and a schematic structural view of a twisting machine using a fifth embodiment of the twisting device of the present invention. The fifth embodiment differs from the fourth embodiment only in that a different type of second-pass twister is used, and the fifth embodiment, as shown in fig. 9, illustrates an example of a typical multiplexed first-pass twister, although the choice of the first-pass twister and the second-pass twister is not fixed for the present invention, and even a twister that performs a third, fourth, or more twisting operations may be added.

Fig. 10 is an external view and a structural view of the first twister of the fourth and fifth embodiments of the twisting apparatus of the present invention. This figure 10 is an enlarged schematic view of the ring spinning twisting assembly employed in the fourth and fifth embodiments, in order to highlight how the open traveler 1312 is clamped to the ring 1311 having an i-shaped cross-section and can freely slide around the ring 1311 over its full turn, and figure 10 also purposely cuts off the ring 1311 to expose its i-shaped cross-sectional shape. As shown in this fig. 10 and with reference to fig. 8 and 9, the core hollow rotating quill 1313 of the ring spinning twisting assembly of the fourth and fifth embodiments is securely mounted on the frame 6 of the twisting machine by means of respective brackets 13.

Fig. 11 is a schematic diagram of the principle and effect of two-stage twisting of the twisting device provided by the present invention. In fact, fig. 11 is an abstraction and summary of all the embodiments described above and thus of the general technical concept of the present invention. As shown in fig. 11, the plurality of raw material threads 7 from the raw material bobbin 4 are clamped by the first twister and then twisted in a rotating manner to form a twisted multi-thread yarn 8 shown in a spiral shape, and it is noted that the raw material threads 7 may be a single roving from a roving bobbin yarn, i.e., a single multi-thread yarn, which is formed by combining a plurality of raw material threads in advance. The open straight arrows in fig. 11 indicate the clamping effect on the multi-strand wire or twisted multi-strand wire 8, and the flattening of the helix at the clamping point indicates the clamping effect. The twisted multi-strand 8 generated after being twisted by the first twister 1 is tightly wound and collected into the rotating body 3, the rotating body 3 also means that the twisted multi-strand 8 is generated by rotating and winding, in order to avoid interference with a related mechanism driving the rotating body 3, the twisted multi-strand on the rotating body 3 serving as an intermediate transmission medium between two twisting operations is output to the second twister 2 through another way from the hollow inside of the rotating body 3 as shown in fig. 11, and in order to enhance the twisting effect of the first twisting operation, the invention also provides the second twister 2, so that the twisting effect of the twisted multi-strand 8 can be enhanced and the twisting return and untwisting condition possibly generated when the multi-strand 8 is untwisted from the rotating body 3 in the practical process can be counteracted. In fig. 11, solid straight arrows indicate the traveling direction of the raw material wire 7, the multi-strand wire or the twisted multi-strand wire 8, and arc arrows indicate the rotating twisting direction of the twister included in the twisting apparatus of the present invention, and it should be noted that in the above embodiment, the rotating twisting direction and the rotating speed of all the twisters can be freely switched and precisely controlled by switching the rotation direction of the corresponding motors and changing the rotating speed of the corresponding motors. Note that although fig. 11 only illustrates two twisters, in actual practice, it is also possible to add a third, a fourth or more twisters, or even to arrange the rotating body between these subsequent twisters as an intermediate medium for transferring and conveying the raw material, and it is only necessary that all the twisters perform the rotating twisting of the multiple strands in the same direction. In fact, all the rotating bodies are the sources of the raw material multi-strand wires of the twisters other than the first twister in the twisting apparatus for the present invention, it should be noted that the double wave wires in fig. 2, 3, 5, 7 and 10 are used to omit the non-essential parts of the parts and the multi-strand wires and twisted multi-strand wires that need not be fully shown. Finally, the terms "multi-strand" and "twisted multi-strand" in the present specification are explained, the "multi-strand" may be a multi-strand obtained by combining a plurality of raw material wires from a plurality of raw material bobbins 4 together through a line concentration ring 12 and not yet twisted, or a twisted multi-strand 8 twisted together in a spiral shape after being twisted, and after all, the term "twisted multi-strand" also belongs to the category of the term "multi-strand".

Detailed Description

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

Specifically, as shown in fig. 11, fig. 1, fig. 4, fig. 6, fig. 8 and fig. 9, the twisting device provided by the present invention is also used to perform a rotary twisting operation on the multiple strands input to the twisting device 0 so as to twist the multiple strands input to the twisting device 0, and the multiple strands subjected to the rotary twisting operation by the twisting device 0 can be output from the twisting device 0 and then wound and collected into a final finished twisted multiple-strand bobbin 5, as in the twisting solutions disclosed so far. As shown in fig. 11 and referring to all the drawings in the specification except fig. 10, the twisting device provided by the invention is different from the twisting technical scheme disclosed at present firstly in that: "the twisting device 0 performs a first twisting operation on the multi-strand input to the twisting device 0 by clamping and rotating the multi-strand composed of the multi-strand raw material 7 input to the twisting device 0 to form a twisted multi-strand 8 generating a twist, the twisting device 0 further winds and collects the twisted multi-strand 8 input to the twisting device 0 and generated after the first twisting operation is performed by means of the rotational winding, the twisted multi-strand 8 wound and collected at one position by means of the rotational winding forms a hollow through rotating body 3, the twisted multi-strand 8 wound and collected on the rotating body 3 can be unwound from the rotating body 3 and output from the hollow through part of the rotating body 3 to the outside of the rotating body 3, and the twisted multi-strand 8 output to the outside of the rotating body 3 is used again by the twisting device 0 to clamp and rotate the twisted multi-strand 8 The twisted multi-strand 8 is rotated to perform a second twisting operation, which is in the same direction as the twist direction of the turns generated by the first twisting operation. "the rotating body 3 shown in fig. 1, 4, 6, 8 and 9 is used as the output source of the multi-strand raw material of the second twisting operation in the present invention, that is, the twisted multi-strand produced after the first twisting operation is temporarily stored in the rotating body as the raw material of the second twisting operation, as if the multi-strand raw material of the first twisting operation is from one or more raw material bobbins. The reason why the twisted multi-strand 8 generated by the first twisting operation is not directly collected and wound into the final finished twisted multi-strand bobbin is that the degree of twisting achieved by the raw multi-strand through only one twisting operation often cannot meet the twisting degree requirement of commercial twisted multi-strands, the invention provides the unique hollow through rotating body 3 as an intermediate material transfer conveying medium between two twisting operations, the direction of twist produced by the second twisting operation as described above is the same as that of the first twisting operation, thus, the twisting degree of the commercial twisted multi-strand yarn can be achieved by the multi-strand raw material yarn through at least two twisting operations, of course, the invention does not exclude the need to provide a third or even more twisting operations in the twisting device provided, as long as the twist directions of the turns produced by all twisting operations are the same. Referring to fig. 1, 4, 6, 8 and 9, the reason why the present invention is to let the twisted multi-strand 8 on the rotating body 3 be unwound and then output from the hollow through part of the rotating body 3 to the outside of the rotating body 3 is that collecting the twisted multi-strand 8 by the rotary winding method is necessarily involved in driving the rotating body 3 to rotate continuously, and therefore, if the twisted multi-strand 8 is spiraled out from the outside of the rotating body 3, it is certainly interfered with the rotary driving device of the rotating body 3. In order to effectively perform the first twisting operation and the second twisting operation, as shown in fig. 1, 4, 6, 8, 9 and 11, the twisting apparatus provided in the present invention includes a first twister 1 for performing the first twisting operation on a plurality of strands inputted to the twisting apparatus and a second twister 2 for performing the second twisting operation on the twisted plurality of strands 8. In addition to the aforementioned enhancement of the twisting effect of the strands fed to the twisting device, the second-pass twister is provided for performing the second-pass twisting operation, and it is also a reason why the inventors found in practice that the twist back already generated when the twisted strands 8 are unwound from the rotary body 3 due to the rotational direction of the rotational unwinding weakens the twisting effect of the first-pass twisting operation, so that the twist back generated when the twisted strands are unwound from the rotary body 3 can be at least offset by the second-pass twisting operation in which the twist direction of the additionally generated twist in the twisting device is the same as the twist direction of the first-pass twisting operation.

As an alternative embodiment of the above technical solution, as shown in the first embodiment indicated in fig. 1 and referring to fig. 2, the twisting device 0 of the first embodiment comprises the first twister 1 which clamps the multiple strands input to the twisting device 0 in a direct clamping manner and rotates the multiple strands to perform the first twisting operation. The direct clamping is to clamp the multi-strand fed into the twisting device 0 tightly after the two pieces are closed, and as in the first embodiment, a pair of rubber rollers 100 is used to directly clamp the multi-strand or the twisted multi-strand 8 generated by twisting. It is apparent from fig. 11 that twisting of the strands to produce a twist can be applied to the strands by rotating the strands while they are clamped, and the advantage of the embodiment using direct clamping is that the clamping of the strands is simple and robust.

As a preferred implementation manner of the above alternative embodiment, the first twister 1 directly clamps the multiple strands fed into the twisting device by using the roller made of elastic material and rotates the multiple strands to perform the first twisting operation, and as shown in fig. 1 and referring to fig. 2, the first embodiment of the present invention uses a pair of rubber rollers 100 made of elastic material. The advantage of using an elastic material is that the articles gripping the strands are in sufficient contact to ensure a gripping effect.

As another alternative embodiment of the above technical solution, as shown in fig. 4, 6, 8 and 9, the twisting device 0 comprises the first twister 1, which is used for bending the multiple strands input into the twisting device 0 under the action of traction force to achieve the clamping effect on the multiple strands and rotating the multiple strands to implement the first twisting operation. As described above, almost all types of twisting machines include a "collecting and winding device" that actively draws and collects twisted strands that are twisted and output from a twisting device and then winds the twisted strands into a final finished twisted multi-strand bobbin, so that the strands that are input to the twisting device and the twisted strands that are generated during twisting are actually always in a drawn state, and thus axial tension exists everywhere, and the reaction force of the resultant force of the axial tension at both sides of the bent portion after the bending of the multi-strand or twisted multi-strand can radially act on the multi-strand or twisted multi-strand, thereby achieving the clamping effect required by the rotational twisting. The embodiment of bending the strands to obtain the clamping effect has the advantage of being able to use the traction force generated by the collecting and winding device in a clever manner without having to provide a mechanical mechanism for direct clamping, the disadvantage of which is that the clamping effect of the strands and twisted strands is affected when they slip at their bending points, which is necessary to ensure that the strands and twisted strands are continuously subjected to a sufficiently large traction force.

As an alternative to the above-described embodiment of directly gripping multiple strands, as shown in the first example indicated in figures 1 and 2, the first twister 1 comprises a hollow through hollow rotating shaft 102 for the penetration of the multiple strands input into the twisting device, the stranded wires penetrate into the hollow interior of the first hollow rotating shaft 102 from an opening at one end of the first hollow rotating shaft 102 and penetrate out from an opening at the other end of the first hollow rotating shaft 102, the first twister 1 further comprises a pair of elastic rubber rollers 100 tightly attached to the first hollow rotating shaft 102, the multiple strands penetrating through the first hollow rotating shaft 102 are tightly clamped by the pair of rubber rollers 100 and rotate along with the first hollow rotating shaft 102 and the rubber rollers 100, so that the first twisting operation is performed on the multiple strands and the twisted multiple strands 8 are generated. In this embodiment, as shown in fig. 1 and fig. 2, when the pair of rubber rollers 100 is rotated by the hollow shaft 102, the multi-strand wires passing through the hollow shaft 102 are actually twisted by rotation to form the twisted multi-strand wires 8. The first hollow rotating shaft 102 is used for introducing the multiple strands input into the twisting device into the first twister and introducing the multiple strands into the pair of rubber rollers 100, and is used for driving the rubber rollers 100 directly clamping the multiple strands to rotate continuously under the driving of the corresponding motor 9 and the driving belt 10 so as to perform rotary twisting operation on the multiple strands. A pair of rubber rollers is adopted to directly clamp the first multiple strands so as to fully clamp the first multiple strands by utilizing the elasticity of rubber, and the second multiple strands can freely roll without hindering the twisted multiple strands 8 generated after the rotary twisting to leave the rubber rollers and then be collected on the subsequent rotary body 3. As shown in fig. 1 and 2, the first twister 1 further comprises a rotating bracket 101 fastened to the first hollow rotating shaft 102, the rotating bracket 101 is used for guiding twisted multiple strands to the rotating body 3 in the present invention, and in the present embodiment, the rotating bracket 101 may be provided with a conduit for passing twisted multiple strands or a pulley 1012 or the like for guiding twisted multiple strands to travel as in the first embodiment. As shown in fig. 1 and 2, the twisting device 0 further includes a second hollow rotating shaft 104 and a hollow penetrating winding drum 103 tightly sleeved on the second hollow rotating shaft 104, the twisted multi-strand 8 generated by the first twister 1 is tightly wound on the winding drum 103 through the rotating bracket 101, the second hollow rotating shaft 104 and the winding drum 103 tightly sleeved thereon are driven by the corresponding motor 9 and the driving belt 10 to rotate in cooperation with the first hollow rotating shaft 102 and the rotating bracket 101, and the rotating speed between the rotating bracket 111 and the winding drum 103 is different, so that the twisted multi-strand 8 leaving the rotating bracket 101 is wound and collected on the winding drum 103 in a rotating winding manner to form a hollow penetrating rotating body 3. The twisted multi-strand 8 wound and collected on the winding drum 103 can be unwound from the winding drum 103 and continuously drawn and output from the winding drum 103 and the hollow through interior of the hollow rotating shaft No. two 104 to the outside of the first twister 1, that is, the twisted multi-strand 8 is unwound from the rotating body 3 and output from the hollow through interior of the rotating body 3, and the power of the continuous drawing shown in fig. 1 is derived from the collecting and winding device commonly equipped in the twisting machine. The second hollow rotating shaft 104 has the functions of driving the winding reel 103 to rotate in cooperation with the rotating bracket 101 so as to wind and collect the twisted multi-strand 8 on the winding reel 103 to form the rotating body 3, and the hollow through interior of the second hollow rotating shaft provides a passage for the twisted multi-strand 8 unwound from the rotating body 3 to leave the rotating body 3. In this embodiment, twisted strands 8 collected on rotor 3 must be tightly wound around bobbin 103, so as to ensure that the rotation speed difference between bobbin 103 and rotating frame 101 can generate enough traction force to continuously pull and wind twisted strands around bobbin 103 to form rotor 3. Specifically, twisted strands 8 are actively wound on drum 103 by rotating frame 101 when the rotating speed of rotating frame 101 is greater than the rotating speed of drum 103 and the two turns are in agreement, and twisted strands 8 are mainly continuously pulled by drum 103 and wound on drum 103 when the co-turning rotating speed of drum 103 is greater than the rotating speed of rotating frame 101. In specific implementation, when the first twister is initialized, an operator needs to manually rotate the first hollow rotating shaft 102 to drive the pair of rubber rollers 100 to rotate so as to carry out rotary twisting on the multiple strands, and then manually pulls the twisted multiple strands 8 to pass through the rotating bracket 101 to tightly wind the winding drum 103 for multiple turns to form the densely wound rotating body 3, so that the first twister 1 can be ensured to smoothly carry out the first twisting operation after the twisting device is started, and the twisted multiple strands 8 are output to the second twister 2. Of course, the operator needs to manually thread the raw material wire 7 through the lower line collector of fig. 1 into the first hollow rotating shaft 102 and the pair of rubber rollers 100, and manually unwind the next twisted multi-strand wire of sufficient length from the tightly wound rotating body 3 through the second twister 2 via the second hollow rotating shaft 104 and tightly wind the twisted multi-strand wire barrel 5 for a plurality of turns until the collection winding device is activated to continuously and effectively draw the twisted multi-strand wire 8 to wind on the finished twisted multi-strand wire barrel 5. In the present implementation, as shown in fig. 1 and referring to fig. 3, the twisted multi-strand 8 output to the outside of the first twister 1 is subjected to the second twisting operation performed by the second twister 2, and as mentioned above, the second twisting operation can further perform rotary twisting on the twisted multi-strand 8 to enhance and ensure the twisting degree of the final product, and can also counteract the untwisting of the twisted multi-strand 8 when unwinding from the rotating body 3, because the twist direction of the twist generated by the second twisting operation is the same as the twist direction generated by the first twisting operation.

As an alternative implementation manner of the above-mentioned embodiment for implementing the clamping effect required by the rotational twisting of the multiple strands by bending the multiple strands under traction force, as shown in fig. 4 and fig. 5 of the second embodiment, the first twister 1 may include a hollow through first hollow rotating shaft 112 for the multiple strands to pass through, the multiple strands pass through the first hollow rotating shaft 112 and then are bent to pass through a winding conduit 111 fastened with the first hollow rotating shaft 112, as before, the multiple strands are clamped at the bent position thereof, the first hollow rotating shaft 112 and the winding conduit 111 may be driven by the corresponding motor 9 and the corresponding transmission belt 10 to rotate so as to implement the first twisting operation on the multiple strands, so that the first twister 1 of this implementation manner introduces the multiple strands into the first twister by means of the first hollow rotating shaft 112 and the winding conduit 111 and enables the multiple strands to be introduced into the first twister and made to pass through the first hollow rotating shaft 112 and the winding conduit 111 Which is bent and rotated to make it twist, the fact that the strands introduced into the first hollow rotating shaft 112 before the bending of the strands are rotated after the first hollow rotating shaft 112 and the winding guide 111 are rotated, the twist is made to be twisted strands 8. As shown in fig. 4 and 5, the twisting device 0 provided in this implementation further includes a second hollow rotating shaft 114 penetrating through the hollow portion and a hollow through bobbin 113 tightly fitted on the second hollow rotating shaft 114, the multiple strands penetrating through the first hollow rotating shaft 114 and the winding guide 111 are subjected to the first twisting operation to become twisted multiple strands 8 and are output from an opening at one end of the winding guide 111, the twisted multiple strands 8 output from the opening at one end of the winding guide 111 are tightly wound on the bobbin 113, the second hollow rotating shaft 114 and the bobbin 113 tightly fitted thereon cooperate with the first hollow rotating shaft 112 and the winding guide 111 to rotate under the driving of the corresponding motor 9 and the corresponding driving belt 10, and there is a difference in rotation speed between the winding guide 111 and the bobbin 113, so that the twisted multiple strands 8 output from the opening at one end of the winding guide 111 pass through the multiple strands 8 The rotating body 3, which is collected on the bobbin 113 to form a hollow penetration, is wound in a rotary winding manner. As shown in fig. 4 and 5 and referring to fig. 1 and 2, the functions of the second hollow rotating shaft 114 and the bobbin 113 are consistent with the functions of the second hollow rotating shaft 104 and the bobbin 103 in the foregoing implementations, and the rotating speed difference is used to wind and collect the twisted multi-strand 8 generated after the first twisting operation together to form the hollow through rotating body 3, and the functions of the first hollow rotating shaft 112 and the winding guide tube 111 in the present implementations are also consistent with the functions of the first hollow rotating shaft 102 and the rotating bracket 101 in the foregoing implementations, except that the foregoing implementations adopt a direct clamping manner to achieve the clamping effect on the multi-strand necessary for rotating and twisting, and in the present implementations, the first hollow rotating shaft 112 and the winding guide tube 111 force the multi-strand to bend to achieve the clamping effect. Of course, in this implementation, as in the first embodiment, the tight winding of the twisted strands 8 on the bobbin 113 is necessary both at the start-up initialization of the twisting device and at the first twisting operation of the strands, since the traction of the strands penetrating the first hollow shaft and of the twisted strands 8 is maintained continuously. Similar to the previous embodiment, in the present embodiment, as shown in fig. 4 and 5, the twisted multi-strand 8 wound and collected on the bobbin 113 can be unwound from the bobbin 113 and continuously drawn out of the first twister 1 from the hollow through interior of the bobbin 113 and the second hollow rotating shaft 114, that is, the twisted multi-strand 8 is unwound from the rotating body 3 and output from the hollow through interior of the rotating body 3, and the continuous drawing force is also from the collecting and winding device equipped in the previous twister as shown in fig. 4, and the twisted multi-strand 8 output out of the first twister 1 is subjected to the second twisting operation performed by the second twister 2, so as to enhance the twisting effect and counteract the possible back-twist untwisting phenomenon.

As another alternative implementation manner of the above-mentioned embodiment that the multi-strand wires subjected to traction force are bent to achieve the clamping effect required by the multi-strand rotary twisting, as shown in fig. 6 and fig. 7, as a third embodiment, the first twister 1 includes a hollow through first hollow rotating shaft 122 and a twisting turntable 121 fastened to the first hollow rotating shaft 122, a rotation axis of the twisting turntable 121 coincides with a rotation axis of the first hollow rotating shaft 122, so that the first hollow rotating shaft 122 can drive the twisting turntable 121 to continuously rotate after being driven to rotate by a dedicated motor 9 and a dedicated transmission belt 10. In this implementation manner, the twisting device further includes a hollow through second hollow rotating shaft 124 and a hollow through winding drum 123 tightly sleeved on the second hollow rotating shaft 124, so that the second hollow rotating shaft 124 can drive the winding drum 123 to continuously rotate under the driving of a dedicated motor 9 and a dedicated driving belt 10, the second hollow rotating shaft 124 is inserted into the hollow interior of the first hollow rotating shaft 122, and the winding drum 123 is located at the center of the interior of the twisting turntable 121. The multi-strand input into the twisting device is bent toward the inner center of the twisting turntable 121 via the edge of the twisting turntable 121 and then tightly wound on the winding cylinder 123, so that the multi-strand bent at the edge of the twisting turntable 121 is continuously pulled at the edge bending position of the twisting turntable 121, the first hollow rotating shaft 122 and the twisting turntable 121 can rotate to perform the first twisting operation on the multi-strand, in this implementation manner, the first hollow rotating shaft 122 actually functions as a driving function for rotating the twisting turntable 121, and the multi-strand 8 generated by the multi-strand input into the twisting device through the rotating twisting of the twisting turntable 121 is tightly wound on the winding cylinder 123 after the edge of the twisting turntable 121 is bent, as shown in fig. 6 and 7 and referring to fig. 11, the multiple strands actually fed into the twisting device are twisted rotationally and generate a twist as the twisted multiple strands 8 after the rotation of the twisting turret 121 is started, that is, the multiple strands fed into the twisting device before the edge of the twisting turret 121 become twisted multiple strands 8 to which the twist is applied after the rotation of the twisting turret 121. Of course, similar to the above-mentioned implementation using the winding guide tube 111 and the bobbin 113, the twisting of the multiple strands 8 is necessary at the start-up initialization of the close winding of the first twister on the winding bobbin 123 and at the time of the rotary twisting of the raw multiple strands after the start-up of the twisting apparatus, because the traction force of the multiple strands bent by the twisting turntable 121 and the twisting multiple strands 8 is continuously maintained. The second hollow rotating shaft 124 and the winding drum 123 tightly sleeved thereon rotate in cooperation with the first hollow rotating shaft 122 and the twisting rotary table 121, and the rotating speed between the twisting rotary table 121 and the winding drum 123 is different, so that the twisted multi-strand 8 bent toward the inner center of the twisting rotary table 121 through the edge of the twisting rotary table 121 is wound and collected on the winding drum 123 in a rotating winding manner and forms a hollow through rotating body 3. The principle of the generation of the rotary winding of the rotary body 3 in this implementation is in fact identical to the previously described principle of winding the collecting twisted strands 8 with the difference in rotation speed between the winding duct 111 and the bobbin 113, and between the rotary support 101 and the bobbin 103. Similar to the two previous implementations, in the present implementation, the twisted multi-strand 8 collected on the winding drum 123 can be unwound from the winding drum 123 and continuously drawn out of the hollow through interior of the winding drum 123 and the second hollow rotating shaft 124 to the outside of the first twister 1 as shown in fig. 6 and 7, that is, the twisted multi-strand 8 is unwound from the rotating body 3 and is output from the hollow through interior of the rotating body 3, the pulling power for continuous drawing is also the collecting and winding device of the twisted multi-strand 8 from the twister equipped with the twisting device, and the twisted multi-strand 8 output to the outside of the first twister 1 as shown in fig. 6 and 7 is subjected to the second twisting operation performed by the second twister 2, and is also subjected to the additional twist on the twisted multi-strand 8 to enhance the degree of twist to satisfy the commercialized twisted product of multi-strand Quality requirements and in order to counteract possible back-off resulting from the twisted strands 8 unwinding from the rotor 3. The difference between the first hollow rotating shaft 122 in this implementation and the first hollow rotating shaft 102 and the first hollow rotating shaft 112 in the foregoing two implementations is that the hollow interior of the first hollow rotating shaft 122 accommodates the rotating shaft required for generating the rotating body 3 and does not guide the multi-strand wire input into the twisting device to the bending position, and the multi-strand wire input into the first twisting device 1 in this implementation goes along the edge of the twisting turntable 121 that bends the multi-strand wire directly without being guided by the hollow rotating shaft. The three implementation modes fully illustrate the implementation feasibility and the diversity of the technical scheme of the invention.

As another alternative implementation manner of the above-mentioned embodiment for implementing the clamping effect required by multi-strand rotary twisting by bending the multi-strand under traction force, as shown in the fourth and fifth embodiments illustrated in fig. 8 to 10, there is a significant difference from the above-mentioned three implementation manners in that the twisting device 0 employed in the fourth and fifth embodiments comprises a ring spinning twisting assembly, specifically, the first twister 1 comprises a hollow through hollow rotating quill 1313, the hollow rotating quill 1313 is inserted into the inner center of a ring-shaped collar 1311, the collar 1311 has an "i" shaped cross section, and a bead 1312 is clamped on the collar 1311, the bead 1312 has a notch thereon, and the elasticity of the bead can ensure that the bead 1312 can be clamped on the collar 1311 by elastically bracing the notch so as not to be clamped on the collar 1311 After slipping off the ring 1311, the traveler 1312 fitted to the ring 1311 can slide freely around the ring 1311 in a complete circle. The strands input to the twisting device penetrate the traveler 1312 and are bent toward the inner center of the ring-shaped ring 1311 via the traveler 1312 and then are tightly wound on the hollow rotating quill 1313. The first twister 1 further comprises a roller mechanism capable of tightly holding the multiple strands and inputting them into the twisting device, which is the pair of rollers 14 as shown in fig. 8 to 10, and the roller mechanism tightly holds the multiple strands by using the rollers and controls the speed of conveying the multiple strands to the first twister 1 to perform the rotary twisting operation by using the rotation speed of the rollers. The hollow rotating quill 1313 included in the first twister 1 can be driven by a dedicated motor 9 and a dedicated transmission belt 10 to continuously rotate so as to drive the multi-strand bent by the traveler 1312 to continuously rotate around the multi-strand output opening of the drum mechanism, so that the first twisting operation is realized and the twisted multi-strand 8 is generated. The multi-strand wires, which are pulled by the hollow rotating quill 1313, generate an axial tensile force, and are clamped at the bending position of the traveler 1312 as before, and the multi-strand wires bent by the traveler 1312 are pulled by the hollow rotating quill 1313 and rotate together with the traveler 1312 on the traveler 1311 at a high speed, so that the multi-strand wires of the first twister 1, which are actually positioned between the roller mechanism and the traveler 1312 and input in the present implementation, become twisted multi-strand wires 8, which generate a twist for the rotary twisting to be implemented, after the hollow rotating quill 1313 starts to rotate. In the present implementation, as shown in fig. 8 to 10, the twisted multi-strand 8 is bent toward the inner center of the ring 1311 through the traveler 1312 and then tightly wound on the hollow rotating quill 1313, the hollow rotating quill 1313 continuously pulls the twisted multi-strand 8 by the rotating winding method and winds and collects the twisted multi-strand 8 on the hollow rotating quill 1313 to form a hollow through rotating body 3, as with all the previous implementations, the tight winding of the twisted multi-strand 8 on the hollow rotating quill 1313 is also necessary for the initial start-up of the first twister 1 and for the implementation of the first twisting operation, because the continuous pulling force of the multi-strand and the twisted multi-strand 8 input to the first twister 1 can be generated only by the tight winding of the twisted multi-strand 8 on the hollow rotating quill 1313 to achieve the clamping effect of the bent portion of the twisted multi-strand 8 on the traveler 1312. As shown in fig. 8 to 10, the rotary twisting method of this embodiment is substantially the same as that of the conventional ring spinning frame, and the present embodiment is different from the conventional ring spinning twisting assembly only in that the twisted multi-strand 8 wound and collected on the hollow rotating quill 1313 can be unwound from above the hollow rotating quill 1313 and continuously drawn out of the hollow through inner portions of the rotating body 3 and the hollow rotating quill 1313 to the outside of the first twister 1, and this process is that the twisted multi-strand 8 is unwound from the rotating body 3 and outputted from the hollow through inner portion of the rotating body 3, and then the multi-strand 8 outputted out of the first twister 1 is subjected to the second-pass twisting operation performed by the second twister 2. The quill of the common ring spinning twisting assembly is generally not hollow, and the twisted multi-strand yarn on the quill can not be unwound from the quill and output from the hollow interior of the quill. The second twisting operation of this embodiment is also for adding a twist to the twisted strands 8 to enhance the degree of twisting and for counteracting possible back-off of the twist resulting from unwinding of the twisted strands 8 from the rotary body 3. For the twisting device provided by the invention, the second twister can adopt all the above-mentioned modes of implementation or any other type of clamping and then rotating twisting mode.

As an alternative embodiment of the technical solution of the present invention, as shown in fig. 3 and referring to fig. 1, 4, 6, 8 and 9, the twisting device 0 includes the second-pass twister 2, which can implement the second-pass twisting operation by bending the twisted multi-strand 8 subjected to the traction force to achieve the clamping effect on the twisted multi-strand 8 and rotating the twisted multi-strand 8. Note that it is also entirely possible for the present invention for the second pass twister 2 to perform the second twisting operation in a directly gripped and rotated manner.

The present invention also provides a twisting machine, as shown in five embodiments indicated in fig. 1, 4, 6, 8 and 9, comprising a twisting device 0 for performing a twisting operation on and outputting a plurality of raw material wires 7 and a frame 6 for mounting the twisting device, different from the common twisting machine, the twisting machine provided by the invention adopts the twisting device 0 provided by the invention to carry out rotary twisting operation on the multi-strand wires input into the twisting device, in this way, the multi-strand fed into the twisting device 0 is guided to the second twister or even more twisters under the continuous pulling of the collecting and winding device of the twisting machine after the rotary twisting of the first twister, so as to enhance the twisting effect, thereby achieving the commercial twisting quality, and after all twisting operations, the collecting and winding device can directly wind the twisted multi-strand 8 into the final finished twisted multi-strand bobbin 5.

It is noted 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 in the present invention, such as providing a ring-shaped recess on the winding reel 103, the winding reel 113, the winding reel 123 and the hollow rotating quill 1313 to facilitate the multi-strand wires being stably wound thereon without being easily unwound; or various sensors are additionally arranged to closely monitor the number of winding turns of the multi-strand wires on the winding reel 103, the winding reel 113, the winding reel 123 and the hollow rotating quill 1313, the speed of the rotating body 3 for collecting and twisting the multi-strand wires 8 is dynamically regulated according to the parameters of the sensors, the rotating speed of the hollow rotating shaft type parts in the twisting device 0 is dynamically regulated, and the like, for example, any modification, replacement, conventional improvement and the like which are made within the technical principle scope of the invention are included within the intellectual property protection scope of the patentee which is stated in the claim of the invention as long as the technical principle of the invention is based on.
