Description

Technical Field

[0001] This invention belongs to the field of textile equipment, and in particular relates to a twisting device and a twisting machine using the said twisting device. Background Technology

[0002] Before spinning yarn, the textile industry typically requires a twisting process to combine two or more raw yarns into a single strand. These two or more strands can originate from multiple yarn bobbins or from a single yarn composed of multiple strands. Twisting is any process in spinning where multiple strands of raw materials, such as slivers, yarns, threads, or filaments, are twisted or wound around their axis to achieve "twisting" or "entanglement." Twisting prevents fibers or filaments from becoming loose or slipping, and imparts certain physical and mechanical properties (such as strength, elongation, and elasticity) and appearance characteristics (such as luster, hairiness, and hand feel). Currently, the main twisting equipment includes "double twisting machines" and "ring spinning machines." The name "double twister" originates from the spindle twisting device it uses, which can achieve a "one-turn, two-twist" twisting effect on a single strand of raw material yarn that has been combined through a doubling operation. In addition to the spindle twisting device, double twisters and almost all types of twisting machines also include a "collecting and winding device" that actively pulls and collects the twisted yarn output from its included twisting device and then winds it into the final finished yarn package. This collecting and winding device typically includes a single continuously rotating roller or a pair of rollers that are close together and rotate in opposite directions; these rollers are commonly referred to as "winding rollers" in the textile industry. Regardless of whether the collecting and winding device uses a single roller, a pair of opposing rotating rollers, or any other configuration, the raw material yarn input into all twisting machines, including double twisters, is subject to the continuous pulling action of the collecting and winding device. When the collecting and winding device uses a single roller, the finished yarn package rotates continuously with the single roller, continuously drawing out the twisted yarn output by the twisting device and winding it into the final finished yarn package. When a pair of opposing rotating rollers are used, the two rollers tightly clamp the yarn output by the twisting device and continuously draw it out from the twisting device before winding it into the finished yarn package. The spindle twisting device used in ring spinning frames differs from that of double twisters; it can only achieve a "single twist per revolution" twisting effect. The ring spinning frame spindle twisting device includes a spindle that continuously rotates the central coil of the yarn package, a traveler that continuously rotates and twists a single raw roving, and a "ring" (the rotating track of the traveler). This device twists a single raw roving into yarn and winds it into a package. Multiple packages are then connected on a winding machine to form the final finished yarn package.

[0003] As mentioned above, both traditional doubling twisters and ring spinning machines require two processes in actual production. For doubling twisters, in addition to their own twisting process, a "combining" process must be performed before the twisting process to combine the multiple strands of raw material yarns that need to be twisted into a single raw material yarn and wind it into a raw material bobbin. For ring spinning machines, since the diameter of the bobbin affects the degree and speed of yarn twisting, the amount of twisted yarn that can be wound on the bobbin cannot be too much. Therefore, the bobbin produced from the ring spinning machine must also go through a process commonly known as "winding" to connect the ends of the yarns on multiple bobbins and wind them into the final finished yarn bobbin.

[0004] In summary, while the two traditional twisting devices, the doubling twister and the ring spinning machine, are ingenious, their drawbacks are also obvious. Both require two different processes. As mentioned earlier, the doubling twister requires two processes: doubling and twisting, while the ring spinning machine requires two processes: spinning and winding. Different processes mean different spaces, production equipment, and energy consumption in both locations. If it were possible to directly generate the final finished yarn cone from multiple raw yarns through doubling and twisting in one process, and to directly generate the final finished yarn cone from a single raw yarn through drafting, twisting, and spinning in one continuous process, it would save the equipment, space, and power required for the doubling and winding processes, greatly improving economic efficiency and product quality. Summary of the Invention

[0005] To address the shortcomings of traditional twisting equipment, including doubling twisters and ring spinning machines, as pointed out in the background section above, this invention provides a twisting device and a twisting machine using the same device. This device can combine the two processes required by traditional doubling twisters and ring spinning machines into one, directly producing finished twisted multi-strand bobbins from multiple raw material bobbins in one go, or producing finished fine yarn from a single roving bobbin in one step.

[0006] Specifically, the twisting device provided by the present invention, like the existing twisting devices, also includes a mounting bracket for mounting the twisting device on a twisting machine. The twisting device is also used to twist the raw material yarn input therein and output it. However, the twisting device provided by the present invention differs from the existing twisting devices in that the twisting device includes a hollow yarn storage device on which the raw material yarn can be wound, and a yarn storage device transmission mechanism that drives the yarn storage device to rotate continuously around its hollow interior. The hollow interior of the yarn storage device is used for the passage of the raw material yarn input into the twisting device. The twisting device also includes two yarn winders fastened together and a yarn winder transmission mechanism that drives the two yarn winders to rotate continuously around the yarn reservoir. The raw material yarn input to the twisting device will pass through the two yarn winders one after the other. The rotational speed of the yarn reservoir driven by the yarn reservoir transmission mechanism can be different from the rotational speed of the two yarn winders driven by the yarn winder transmission mechanism. Either of the two yarn winders can be selected to wind the raw material yarn input to the twisting device onto the yarn reservoir, while the other yarn winder will be used to unwind the raw material yarn wound onto the yarn reservoir and output it. In fact, the function of the yarn storage device in this invention is to serve as a temporary winding and collection point for the twisted raw material yarn. One of the two winding devices uses its own rotation around the yarn storage device to perform a twisting operation on the raw material yarn input into the twisting device of this invention, and also uses its own rotation around the yarn storage device to wind the twisted raw material yarn into the yarn storage device for temporary collection. The raw material yarn temporarily wound and collected on the yarn storage device will be unwound from the yarn storage device under the pull and guidance of the other winding device and output to the collection and winding device of the twisting machine using the twisting device.One reason why this invention sets up a yarn storage device as an intermediate winding and collecting point instead of directly outputting the twisted raw yarn to the collecting and winding device of the twisting machine is that the diameter and volume of the finished yarn package produced by the twisting machine are often very large. If the yarn winder, which performs the twisting operation, directly winds the finished yarn package, the rotation radius of the yarn winder around the finished yarn package would be very large, resulting in high air resistance and frictional resistance on the yarn winder's transmission mechanism during rotation. This would be detrimental to saving energy consumption and space occupied by the twisting machine. The reason why this invention designs the yarn storage device as hollow and through is that the yarn storage device and the two yarn winders that are fastened together actually constitute the core twisting component of the twisting device provided by this invention. Among the three components, only the yarn storage device rotates around itself, while the two yarn winders actually rotate around the yarn storage device. Since the yarn revolves around the core twisting component, whether guiding the raw material yarn to be twisted into the core twisting component or outputting the twisted raw material yarn outside the core twisting component or even outside the entire twisting device, allowing the raw material yarn to travel in a straight line through the hollow interior of the yarn storage container (which does not participate in rotation) can avoid unnecessary revolution of the raw material yarn around the yarn storage container. This avoids unnecessary air resistance, thereby saving energy consumption of the twisting machine using the twisting device of the present invention and saving the volume occupied by the core twisting component and even the entire twisting device. Moreover, the outside of the yarn storage container is already used to wind and collect the twisted raw material yarn, and two yarn winders are constantly revolving around it in a 360-degree omnidirectional rotation. Therefore, in the present invention, the outer surface of the yarn storage container can no longer provide a passage for the raw material yarn. Only by hollowing out the interior of the yarn storage container can a smooth and low-resistance straight passage for the raw material yarn be opened. Note that for the twisting device provided by the present invention, the raw material yarn input into the twisting device can either first pass through one of the two yarn winders, then be wound around the outer surface of the yarn storage device, and then be unwound from the yarn storage device under the traction of the other yarn winder, and then be output from the core twisting component or even the entire twisting device through the hollow through-hole of the yarn storage device; or it can first enter the core twisting component from the hollow through-hole of the yarn storage device, then be pulled to one of the two yarn winders through the hollow through-hole of the yarn storage device and pass through it, and then be wound around the outer surface of the yarn storage device, and then be unwound from the yarn storage device under the traction of the other yarn winder, and then be output from the core twisting component or even the entire twisting device through the other yarn winder.Furthermore, it should be noted that in this invention, the two winding devices are fastened together, so their rotational speeds around the yarn storage device are consistent. Therefore, the speed at which the twisted raw material yarn is wound and collected onto the yarn storage device and the speed at which the raw material yarn is unwound from the yarn storage device are consistent. Thus, there is no need to worry about the amount of raw material yarn temporarily wound and collected on the yarn storage device increasing indefinitely. Moreover, in this invention, the reason why the rotational speed of the yarn storage device driven by the yarn storage device transmission mechanism can be set to be different from the rotational speeds of the two winding devices driven by the winding device transmission mechanism is to control the number of turns of the raw material yarn temporarily wound and collected on the yarn storage device. That is, the difference in rotational speed between the yarn storage device and the two winding devices is used to control the amount of raw material yarn wound and collected on the yarn storage device to maintain it at a suitable level. Furthermore, it should be pointed out that an important technical feature of the present invention is that the raw material yarn located between the raw material yarn input end of the twisting device and the raw material yarn output end of the winding device that winds the raw material yarn input into the twisting device onto the yarn storage device will bend under continuous tension. This is actually a necessary and sufficient condition for the twisting device provided by the present invention to perform the necessary twisting operation on the raw material yarn. As mentioned above, almost all types of twisting machines, including the most common doubling twister, include a "collecting and winding device" that actively pulls and collects the twisted multi-ply yarn output from the twisting device and then winds it into the final finished yarn cone. Therefore, a twisting machine using the twisting device provided by this invention must also include the collecting and winding device that actively pulls, collects, and winds the raw material yarn after it has been twisted and output by the twisting device. This provides a continuous pulling force on the raw material yarn input to the twisting device. Under the continuous pulling force, the raw material yarn is clamped at the bend. Before being wound by the yarn winder to the yarn storage device, the clamped raw material yarn will continuously revolve around the yarn storage device with the yarn winder, thereby realizing the desired twisting operation of the raw material yarn. Of course, in this invention, when the rotational speed, i.e., the angular velocity, of the yarn storage device and the two yarn winders is different, the yarn storage device, as an intermediate temporary collection point for the raw material yarn, will also apply a continuous tension force to the raw material yarn input into the twisting device, especially into the core twisting assembly. In addition to using the yarn winders, which continuously revolve around the yarn storage device, to twist the raw material yarn, this invention can also use the yarn storage device to perform twisting operations on the raw material yarn input into the core twisting assembly and even the entire twisting device.As described above, the raw material yarn input to the core twisting component and even the twisting device can either first pass through any of the yarn winders and then be wound onto the yarn storage device, or it can first pass through the hollow passage of the yarn storage device and then be pulled to a selected yarn winder. In fact, under both working conditions, the raw material yarn input to the twisting device will be bent and clamped when entering and exiting the hollow passage of the yarn storage device while being continuously pulled, and thus be twisted as the yarn storage device rotates. If the raw yarn input to the twisting device first passes through one of the yarn winders and is then wound onto the yarn reservoir, then under this condition, the raw yarn unwound from the yarn reservoir by another yarn winder and then passed through the hollow passage of the yarn reservoir will inevitably bend when it enters the hollow passage of the yarn reservoir. This is because both yarn winders will revolve around the yarn reservoir, so they cannot be located on the central axis of the hollow passage of the yarn reservoir. Furthermore, under this condition, the twisted yarn exiting from the hollow passage of the yarn reservoir will be subjected to the continuous tension of the collecting and winding device of the twisting machine, thus causing it to bend as it enters the hollow passage. The portion of raw material yarn that passes through the hollow interior of the yarn storage device and is then output to the collecting and winding device of the twisting machine will definitely be clamped at the bend, thus being twisted as the yarn storage device continues to rotate. It should also be noted that under this condition, when the raw material yarn is wound onto the yarn storage device from the first winding device, the raw material yarn will also bend when it leaves the first winding device, and this bending will also occur under continuous tension. This bending that occurs before the raw material yarn leaves the winding device and is wound onto the yarn storage device allows the winding device to twist the raw material yarn through its revolution around the yarn storage device. The raw yarn input to the twisting device is first fed into the twisting device through the hollow passage of the yarn storage unit. Since the two yarn winders revolve around the yarn storage unit in this invention, when the raw yarn is pulled from the hollow passage of the yarn storage unit to either of the yarn winders, it will inevitably bend at the exit of the hollow passage of the yarn storage unit. As the subsequent yarn is not only continuously pulled by the collecting and winding device of the twisting machine, but also, as mentioned above, the difference in rotational angular velocity between the yarn storage unit and the yarn winder will generate a continuous pulling force on the raw yarn inside the hollow passage of the yarn storage unit. Thus, the raw yarn pulled from the hollow passage of the yarn storage unit to the yarn winder will be clamped at the bend at the exit of the hollow passage of the yarn storage unit, so that the raw yarn input to the twisting device will be twisted at the exit of the hollow passage of the yarn storage unit as the yarn storage unit continues to rotate.It should also be noted that under this operating condition, when the raw material yarn is pulled from the hollow interior of the yarn reservoir to a selected winding device, the raw material yarn will also bend on the selected winding device. Due to the continuous pulling force from the collecting and winding device of the twisting machine and the continuous pulling force generated by the difference in rotational angular velocity between the yarn reservoir and the winding device, the bent portion of the raw material yarn on the selected winding device will be clamped, thus twisting the raw material yarn as the winding device continuously revolves around the yarn reservoir. In summary, regardless of the operating condition of the twisting device or any different path of the raw material yarn in the twisting machine using the twisting device, the twisting device can twist the raw material yarn through the rotation of the yarn reservoir and the revolution of the winding device. Especially when the rotational angular velocities of the yarn reservoir and the winding device are different, the difference in the amount of twist applied to the raw material yarn per unit time can also offset any possible unwinding of the twisted raw material yarn. This is one reason why the present invention is equipped with a yarn storage device that has a hollow, through-hole interior and can rotate continuously.

[0007] As an optimized implementation of the basic technical solution of the present invention, the yarn storage device is designed as a hollow, through-hole yarn storage cylinder. The twisting device includes a yarn storage device transmission mechanism that drives the yarn storage cylinder to rotate continuously around its hollow, through-hole internal axis. The advantage of designing the yarn storage device as a long, thin cylindrical structure is that its long, thin cylindrical outer surface not only allows the raw material yarn to be easily wound multiple times for temporary collection, but also facilitates separating the winding and unwinding positions of the raw material yarn by a certain distance to avoid unnecessary interference between the raw material yarn wound on the yarn storage device and the raw material yarn unwound from the yarn storage device.

[0008] As a preferred embodiment of the above-mentioned optimized implementation scheme, both yarn winders are fastened to the edge of a hollow, through-hole yarn winding disc. The yarn winding disc transmission mechanism included in the twisting device is a yarn winding disc transmission mechanism that drives the yarn winding disc to rotate continuously around its hollow, through-hole interior. Under the drive of the yarn winding disc transmission mechanism, the yarn winding disc will rotate continuously around the rotation axis of the yarn storage cylinder, thereby causing the two yarn winders to rotate continuously around the yarn storage cylinder. The hollow, through-hole interior of the yarn winding disc is used for the passage of the raw material yarn into the twisting device. Fastening both yarn winders to the edge of the same hollow, through-hole yarn winding disc serves two purposes: firstly, it allows both yarn winders to continuously rotate around the yarn storage device by driving a single yarn winding disc; secondly, the hollow interior of the yarn winding disc acts as a straight passageway for the raw material yarn entering and exiting the core twisting component. After all, both yarn winders will continuously revolve around the yarn storage device during operation. Directly passing the yarn winders into and out of the core twisting component of the twisting device provided by this invention would inevitably create unnecessary rotating air rings in the raw material yarn, thus increasing air resistance and energy consumption of the twisting machine using the twisting device. As mentioned above, the yarn storage device continuously rotates around its hollow interior. In this embodiment, the rotation axis of the winding disc coincides with the rotation axis of the yarn storage device. Given the circumferential symmetry of the winding disc itself, the hollow interior of the yarn storage device and the hollow interior of the winding disc form a running channel for the raw material yarn that coincides with the same straight line. This avoids unnecessary rotational changes that increase air resistance and energy consumption when the raw material yarn passes through the core twisting component and the entire twisting device. Note that in this embodiment, the raw material yarn can either be input into the twisting device through the hollow interior of the yarn storage device (i.e., the yarn storage cylinder) and then output from the hollow interior of the winding disc, or it can be input into the twisting device from the hollow interior of the winding disc and then output from the hollow interior of the yarn storage device. When a twisting machine using the twisting device provided by the present invention actually performs the twisting of multi-strand raw material yarns or the twisting of single-strand roving yarns, it can flexibly choose whether to input the core twisting component from the hollow through-hole of the yarn storage device or from the hollow through-hole of the yarn winding disc, and reasonably and dynamically modulate the rotation direction and speed of the yarn storage device drive mechanism and the yarn winding device drive mechanism to drive the yarn storage device and the yarn winding device.For a twisting machine using the twisting device provided by the present invention, before starting use, multiple or single strands of raw material yarn need to be drawn from the hollow interior of the yarn storage container or the winding disc into the twisting device. Then, the raw material yarn is manually wound around the outside of the yarn storage container a few times to complete the initialization of the yarn storage container. After that, it is pulled to the collecting and winding device of the twisting machine. Then, the twisting machine can be started to continuously perform twisting operations on multiple or single strands of raw material yarn and directly produce the finished product yarn cone in one step.

[0009] As a further optimized embodiment of the above preferred embodiment, the twisting device includes two yarn winders that are two hollow, through-hole yarn winding shafts of different lengths. The hollow interiors of both the long and short yarn winding shafts can be used for the passage of the raw material yarn into the twisting device. It should be noted that, firstly, the reason for designing the yarn winders as hollow and allowing the raw material yarn to pass through their hollow interiors in this embodiment is to simplify the function of the yarn winders in pulling and passing the raw material yarn. After all, compared to the simple drilling on a lathe or the one-step tube-drawing process on a broaching machine, fastening the components for pulling and passing the raw material yarn onto the yarn winders is redundant, time-consuming, and costly. Secondly, designing the two yarn winders as one long and one short helps to separate the winding and unwinding positions of the raw material yarn on the yarn storage device, avoiding unnecessary interference between the winding, collection, and unwinding of the raw material yarn on the yarn storage device.

[0010] As a preferred embodiment of the above-mentioned optimized preferred embodiment, both the yarn storage cylinder transmission mechanism and the yarn winding disc transmission mechanism are driven by the same transmission shaft. Both mechanisms are belt-driven transmission mechanisms, including a driving pulley, a driven pulley, and a transmission belt. The yarn storage cylinder transmission mechanism and the yarn winding disc transmission mechanism form a coaxial asynchronous transmission mechanism that drives the yarn storage cylinder and the yarn winding disc to rotate continuously at different speeds. The reason for choosing belt drive as the transmission mechanism for both the yarn storage cylinder and the yarn winding disc is the stability and low failure rate of belt drive mechanisms. The advantage of using the same transmission shaft to simultaneously drive two transmission mechanisms is obvious compared to using two separate motors to independently drive two transmission mechanisms.

[0011] Finally, the present invention also provides a twisting machine, which, like existing twisting machines such as doubling twisters and ring spinning machines, is used to twist multi-strand or single-strand raw material yarns and then wind them into finished yarn bobbins. The twisting machine provided by the present invention also includes the aforementioned collecting and winding device for winding the twisted raw material yarns into finished yarn bobbins. The only difference between the twisting machine provided by the present invention and existing twisting machines is that it uses the aforementioned twisting device provided by the present invention.

[0012] In summary, the present invention provides a twisting device and a twisting machine using the twisting device. By continuously rotating and twisting multiple or single strands of raw material yarn through the twisting device and cooperating with the collecting and winding device of the twisting machine, the two processes required by the traditional doubling machine and the ring spinning machine can be conveniently integrated into one twisting machine and completed in one go. It successfully achieves the production goals of the two separate processes of the traditional doubling machine and the ring spinning machine in one step using a single twisting machine, saving space, energy consumption and corresponding labor costs. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the external appearance of a first embodiment of the twisting device provided by the present invention from three perspectives. The diagram is divided into three sub-views from left to right by three vertical dotted lines. These three sub-views represent three different perspectives of the external appearance of a typical embodiment of the twisting device provided by the present invention, with the reference numerals at the ends of the lead wires of important components marked with a gray background. Figure 1 It can be seen that the mounting bracket 2 included in the first embodiment for mounting the first embodiment onto the twisting machine is actually also the support bracket for the yarn storage cylinder 104 and the yarn storage cylinder drive mechanism 102 included in the twisting device, the two winding shafts including the long winding shaft 1051 and the short winding shaft 1052, the winding disc 5 and the winding disc drive mechanism 103 fastened to the two winding shafts, and the support bracket of the two winding shafts fastened to the winding disc drive mechanism 103. Figure 1 Combined with the following Figure 2 It can be seen that the yarn storage device in the first embodiment adopts a hollow, through-hole yarn storage cylinder 104. The continuous rotation of the yarn storage cylinder 104 is driven by a belt-driven yarn storage cylinder transmission mechanism 102, which includes a transmission belt 1020, a driving wheel 1021, and a driven wheel 1022. Meanwhile, another belt-driven yarn winding disc transmission mechanism 103, which includes a transmission belt 1030, a driving wheel 1031, and a driven wheel 1032, is responsible for driving the two winding shafts to continuously rotate around the yarn storage cylinder 104 by driving the hollow, through-hole yarn winding disc 105. That is, the two winding shafts in the first embodiment are two yarn winders, and the yarn winding disc transmission mechanism 103 is the yarn winder transmission mechanism in the basic technical solution of this invention. Through this… Figure 1The rightmost view shows that the yarn storage cylinder transmission mechanism 102 and the yarn winding disc transmission mechanism 103 share the same transmission shaft 101. This simplifies the design of the twisting device. In the first embodiment, the speeds of the yarn storage device and the yarn winding device can be precisely modulated by two belt drive mechanisms. Therefore, using the same transmission shaft 101 to drive the two transmission mechanisms also ensures the speed difference between the yarn storage device and the yarn winding device. Note that the first embodiment omits the motor that drives the transmission shaft 101, and the upper part of the transmission shaft 101 also includes a coupling. However, these are common knowledge for those skilled in electromechanical engineering and will not be described in detail here.

[0014] Figure 2 This is a schematic cross-sectional view of the first embodiment of the twisting device provided by the present invention, showing the device passing through a yarn winding axis. This figure is consistent with... Figure 1 Similarly, the left and right sub-views are divided by dotted lines. The viewing angles of the left and right sub-views in this figure are completely identical. The only difference between the two sub-views is that the left view shows a cross-sectional schematic diagram of the twisting device represented by the first embodiment through the center lines of the two yarn axes, while the right view, based on the left view, shows the path of a raw material yarn in actual use of the first embodiment. The right view of this figure is actually a schematic diagram of the twisting principle of a twisting machine provided by the present invention using the first embodiment. Figure 2 As shown in the right view, the multi-strand raw material yarns from multiple raw material yarn cones 4 are combined into a single raw material yarn in the twisting machine provided by the present invention, thus completing the aforementioned yarn doubling operation. Then, under the opposing rotation clamping of a pair of rollers in the direction indicated by the arc arrow, the yarn is continuously pulled and input into the twisting device 1 provided by the present invention. The raw material yarn twisted by the twisting device 1 is continuously pulled and output outside the twisting device 1 under the opposing rotation clamping of another pair of rollers in the direction indicated by the arc arrow, as shown in the upper right view, and is finally wound into the finished yarn cone 5. In this way, the twisting machine provided by the present invention using the twisting device provided by the present invention achieves the production effect of one-step production from raw material yarn cones to finished yarn cones in one go. Compared with the existing double twisting machine and ring spinning machine, which require two processes to achieve the production from raw material yarn cones 4 to finished yarn cones 5, the advantages of the present invention are obvious. Note that although the right view of this figure shows the process of forming a single twisted yarn from multiple strands of raw material yarn through twisting, the two raw material yarn cones 4 at the bottom of the right view can be completely replaced by a single roving raw material yarn cone. In that case, the twisting device and twisting machine shown in the right view will complete the production of the finished yarn cone from the roving raw material yarn cone in the same way, that is, complete the production process that traditional ring spinning machines require two steps: twisting and winding. Note that the right view of this figure... Figure 1Similarly, the motor driving the drive shaft 101 is omitted from the diagram. Only a pair of arc-shaped arrows above the drive shaft 101 in the right view indicate that the drive shaft 101, included in the twisting device 1, will be driven to rotate continuously, thereby driving the yarn storage device's transmission mechanism. Also note that in the right view, the raw yarn and the twisted yarn first enter the twisting device 1 through the hollow passage below the winding disc 105, then bend and enter the hollow passage of the long winding beam 1051. As shown in this figure, the twisted yarn exiting from the opening at the upper end of the long winding beam will be wound onto the yarn storage cylinder 104 of the first embodiment. The raw yarn input to the twisting device 1 can be twisted because it rotates continuously under continuous tension and bending. Figure 2 The bending shown has at least three points: one is the outlet inside the hollow passage of the yarn winding disc 105; one is the inlet of the raw material yarn below the long winding beam 1051; and the third is the opening inside the hollow passage above the long winding beam 1051 where the yarn outputs. The raw material yarn and the twisted yarn are continuously pulled by the collecting and winding device of the twisting machine. Furthermore, when the rotational speeds of the yarn storage device and the yarn winding device are different, i.e., when their angular velocities are different, the raw material yarn and the twisted yarn are also subjected to a continuous pulling force from the yarn storage device. In the first embodiment, since the diameter ratio of the driving wheel to the driven wheel of the yarn storage cylinder transmission mechanism 102 and the yarn winding disc transmission mechanism 103 driving the yarn storage device and the yarn winding device is significantly different (visibly visible) as shown in this figure, the yarn is subjected to a continuous pulling force from the moment it enters the hollow passage below the yarn winding disc 105. Thus, under continuous tension, the raw material yarn, whether it is a single strand or a multi-strand yarn, will be clamped at the bend. Then, as the raw material yarn rotates continuously around the yarn storage cylinder in the first embodiment, the required twisting is completed. Note that in the right view, the direction of the raw material yarn input to the twisting device 1 and the twisted yarn is as follows: the raw material yarn first bends into the long winding beam 1051, and the yarn after completing the rotational twisting operation is as shown in the diagram. Figure 2 As shown, the yarn is temporarily wound and collected on the yarn storage cylinder 104. The yarn wound on the yarn storage cylinder 104 will be wound on another yarn bobbin, that is, as shown in the figure. Figure 2 The short yarn bobbin 1052 shown guides the yarn unwinding from the yarn storage cylinder 104 and outputs it through the hollow interior of the short yarn bobbin 1052 and the yarn storage cylinder 104 to the outside of the core twisting assembly and even the entire twisting device 1. The yarn output outside the twisting device 1 is as shown in this diagram. Figure 2The right view shows that the yarn is collected and wound into a finished yarn cone by the collecting and winding device. It should be noted that the uses of the two winding shafts in the first embodiment, and even the two winding devices in the basic technical solution of this invention, can be switched between each other, just like in this... Figure 2 The raw material yarn input to the twisting device 1 can be either bent and twisted by the long winding beam 1051, then wound onto the yarn storage cylinder 104, and then unwound from the yarn storage cylinder 104 by another short winding beam 1052, or it can be bent and twisted by the short winding beam 1052, then wound onto the yarn storage cylinder 104, and then unwound from the yarn storage cylinder 104 by the long winding beam 1051. As shown in the figure... Figure 2 As shown, since the two yarn winders are fastened together in this invention, their rotational speed around the yarn reservoir is the same. This allows them to wind the twisted yarn onto the yarn reservoir at the same speed while simultaneously unwinding the yarn wound onto the yarn reservoir in the opposite direction, thereby maintaining the number and quantity of twisted yarn temporarily wound and collected on the yarn reservoir. Maintaining a certain number of twisted yarn turns on the yarn reservoir helps to utilize the difference in rotational angular velocity between the yarn reservoir and the yarn winder to draw and wind the twisted yarn onto the yarn reservoir. Finally, it should be noted that although this... Figure 2 The right view shows the raw material yarn entering the core twisting component of the twisting device 1 via a yarn winder (represented by a yarn winding beam) and finally exiting the core twisting component and even the entire twisting device via a yarn storage device (represented by the yarn storage cylinder 104). However, in actual use, it is entirely possible to choose to have the raw material yarn first enter the core component through the hollow interior of the yarn storage device, then be twisted and wound onto the yarn storage device after being bent and rotated by any yarn winder, and finally unwound from the yarn storage device via another yarn winder and exited the core twisting component via that other yarn winder. For the first embodiment, refer to this... Figure 2 and the following Figure 3 In other words, the raw material yarn can be fed into the core component through the hollow interior of the yarn storage cylinder 104, then twisted and wound onto the yarn storage cylinder 104 after being bent and rotated by any one of the yarn shafts, and finally unwound from the yarn storage cylinder 104 via another yarn shaft and output to the outside of the core twisting component. From this figure combined with the aforementioned basic technical solution of the present invention, one can see the flexibility and ease of operation in the specific implementation of the technical solution of the present invention.

[0015] Figure 3 This is a schematic diagram illustrating two twisting principles of a twisting machine using the aforementioned twisting device, provided by the present invention. Figure 2 One copy Figure 3A vertical dotted line is used to divide the left and right sub-views to illustrate two typical and different yarn travel paths that a twisting machine using the twisting device provided by this invention can adopt in actual use. (Refer to this...) Figure 3 and Figure 2 It should be noted that the twisting device 1 provided by this invention can be used for two main categories and four types of yarn threading methods. Figure 3 Only two of the four methods are shown. Based on whether the raw yarn input to the twisting device first passes through the hollow interior of the yarn storage unit or through a yarn winder into the core twisting component or even the entire twisting device, the yarn's path within the twisting device can be divided into two main categories. Then, within each category, based on which of the two yarn winders the yarn first passes through after entering the twisting device, each category can be further divided into two yarn path patterns. Specifically, for example... Figure 2 and this Figure 3 In the first embodiment shown, the yarn's path through the twisting device 1 can be divided into two main categories based on whether the raw material yarn first passes through the hollow interior of the yarn storage cylinder 104 or the hollow interior of the winding disc and then through the winding shaft to the core twisting component or even the entire twisting device. Within each category, the yarn's path can be further subdivided into two types based on which of the two winding shafts it first passes through after entering the twisting device. (Reference) Figure 2 and Figure 3 For the twisting machine using the first embodiment, the two main categories correspond to two yarn passing methods with the directions of travel being exactly reversed. These two categories of yarn passing methods are also necessarily reflected in the position of the collecting and winding device of the finished yarn package 5. Figure 2 and Figure 3 This includes whether the yarn is positioned above or below the twisting machine, and whether the raw material yarn 4 is placed above or below the twisting machine. Furthermore, it should be noted that the raw material yarn input into the twisting device 1 can be as follows... Figure 3 The right subview and Figure 2 The right view shows multi-strand raw material yarns derived from multiple raw material bobbins 4, or as shown in this... Figure 3 The left view shows a single strand of raw material yarn originating from a single raw material bobbin 4. This also illustrates that the twisting machine using the twisting device 1, represented by the first embodiment of the present invention, can complete the twisting operation of a traditional doubling machine in one step, as well as the twisting operation of an existing ring spinning machine. Please also note that... Figure 3 and Figure 2 The curved arrow inside the circular roller indicates the direction of rotation of the yarn as it is held and pulled by the roller's rolling motion. Figure 3The twisting machine shown in the left and right sub-views has installation positions and working surfaces for the twisting device 1 on both the front and rear sides, reflecting this. Figure 3 The frame 3 of the twisting machine is symmetrical from left to right. This is to highlight all the yarns, including the raw yarn and the twisted yarn. Figure 3 The two sub-views show the twisting machine, each using only one working side to demonstrate the twisting operation, while the other side can be used to compare and highlight the components of the twisting device. Figure 3 The left view illustrates the spinning process starting with a single roving bobbin above the twisting machine, as shown in the left view and referenced. Figure 1 and Figure 2 The single-strand raw material yarn is first fed into the core twisting component of the twisting device 1 through the hollow interior of the yarn storage cylinder 104. The raw material yarn output from the hollow interior of the yarn storage cylinder 104 is bent and wound onto the yarn storage cylinder 104 through the hollow interior of the long winding beam 1051. During this process, as the long winding beam 1051 rotates continuously with the winding disc 105, it performs a twisting operation on the bent raw material roving to generate twisted fine yarn, which is then wound into the yarn storage cylinder 104 for temporary collection. The fine yarn is then unwound from the yarn storage cylinder 104 through the short winding beam 1052 and output to the core twisting component and even the collection and winding device outside the entire twisting device 1 through the hollow interior of the short winding beam 1052 and the winding disc 105 to be wound into the finished yarn package 5. Note that the yarn weaving pattern of the entire single-strand raw material yarn in the left view is also fully applicable to the plying and twisting operations of multi-strand raw material yarns, similar to this... Figure 3 The right view shows that it is feasible to first thread the twisted yarn onto the long winding beam 1051 or the short winding beam 1052, depending on the difference in output speed between the yarn storage cylinder transmission mechanism 102 and the winding disc transmission mechanism 103. Figure 3 The right view illustrates the yarn doubling and twisting operation, which begins with multiple raw material bobbins below the twisting machine. (See right view and reference.) Figure 1 and Figure 2Multiple strands of raw material yarn are first fed into the core twisting component of the twisting device 1 through the hollow interior of the winding disc 105. The raw material yarn output from the hollow interior of the winding disc 105 is bent and wound onto the yarn storage cylinder 104 through the hollow interior of the long winding beam 1051. During this process, as the long winding beam 1051 rotates with the winding disc 105, it performs a twisting operation on the bent yarn composed of multiple strands of raw material roving to generate twisted yarn, which is then wound onto the yarn storage cylinder 104 for temporary collection. The twisted yarn is then unwound from the yarn storage cylinder 104 through the short winding beam 1052 and output to the core twisting component and even the collection and winding device outside the entire twisting device 1 through the hollow interior of the short winding beam 1052 and the yarn storage cylinder 104 to generate the finished yarn package 5 located above the twisting machine. Note that the entire yarn routing pattern in the right-hand view is also fully applicable to the twisting and spinning operation of yarns derived from single-strand raw materials, similar to this... Figure 3 The left view. Moreover, it is feasible to first thread the yarn through the long winding beam 1051 or the short winding beam 1052 before twisting, depending on the difference in output speed between the yarn storage cylinder transmission mechanism 102 and the winding disc transmission mechanism 103.

Implementation

[0017] The present invention will now be described in detail using a specific typical embodiment and in conjunction with the content of the aforementioned three sections: "Background Art", "Summary of the Invention" and "Description of Drawings".

[0018] Specifically, the present invention provides a twisting device 1, such as... Figure 1 As shown and referenced Figure 2 Similar to existing twisting devices, this invention also includes a mounting bracket 2 for mounting the twisting device 1 onto a twisting machine. The twisting device 1 is also used to twist the raw material yarn input therein before outputting it. However, the twisting device 1 provided by this invention differs from existing twisting devices primarily in that it includes a hollow, through-hole yarn storage container on which the raw material yarn can be wound, and a yarn storage container transmission mechanism that drives the yarn storage container to rotate continuously around its hollow interior. The hollow interior of the yarn storage container is used for the passage of the raw material yarn input into the twisting device. Figure 1 As shown and referenced Figure 2 and Figure 3 In the first embodiment, the yarn storage device is also the hollow, through-hole yarn storage cylinder 104, and the yarn storage device transmission mechanism is also the yarn storage cylinder transmission mechanism 102 shown in the three figures. In this invention, the twisting device further includes two yarn winders fastened together and a yarn winder transmission mechanism that drives the two yarn winders to continuously rotate around the yarn storage device. The raw material yarn input into the twisting device will pass through the two yarn winders sequentially, such as... Figure 1 As shown and referenced Figure 2 and Figure 3 In the first embodiment, the prime number yarn winder includes the long yarn winding shaft 1051 and the short yarn winding shaft 1052 shown in the figure, and the yarn winder transmission mechanism is the yarn winding disc transmission mechanism 103 shown in the figure; in this invention, the rotational speed of the yarn storage device driven by the yarn storage device transmission mechanism can be different from the rotational speed of the two yarn winders driven by the yarn winder transmission mechanism, such as... Figure 1 As shown and referenced Figure 2 In the first embodiment, the yarn storage cylinder transmission mechanism 102, representing the yarn storage device transmission mechanism, and the yarn winding disc transmission mechanism 103, representing the yarn winding device transmission mechanism, have obviously opposite-sized driving and driven wheels. Driven by the same transmission shaft 101, the rotational speeds of the yarn storage cylinder 104 and the two winding shafts are significantly different, and the difference in rotational speed between them can be precisely changed. In this invention, either of the two yarn winding devices can be selected to wind the raw material yarn input to the twisting device onto the yarn storage device, while the other yarn winding device is used to unwind the raw material yarn wound onto the yarn storage device and output it. Figure 2 As shown and referenced Figure 3 In the first embodiment, the two winding shafts, which are the specific implementation of the yarn winder, can indeed achieve the above-mentioned winding of the yarn onto the yarn reservoir and simultaneously unwinding the yarn from the yarn reservoir. For example... Figure 2 and Figure 3 The yarn storage device 104 shown in the invention serves as a temporary winding and collection point for the twisted raw material yarn; see reference Figure 2 and Figure 3The first embodiment of the present invention uses two yarn winding bobbins. One of the two yarn winding devices in this invention uses its own rotation around the yarn storage device to twist the raw material yarn input to the twisting device of this invention, and also uses its own rotation around the yarn storage device to temporarily collect the twisted raw material yarn. The raw material yarn temporarily collected on the yarn storage device is unwound from the yarn storage device under the pull and guidance of the other yarn winding device and output to the collection and winding device of the twisting machine using the twisting device. It should be noted that one reason why this invention sets up an intermediate winding and collection point such as the yarn storage device represented by the hollow yarn storage cylinder shown in the first embodiment, instead of directly outputting the twisted raw material yarn to the collection and winding device of the twisting machine, is that the diameter and volume of the finished yarn package produced by the twisting machine are often very large. If the yarn winding device performing the twisting operation were to directly wind the finished yarn package, the rotation radius of the yarn winding device around the finished yarn package would be... Figure 2 and Figure 3 This would result in significant air resistance during the rotation of the yarn winder and frictional resistance on its transmission mechanism, which would be detrimental to saving energy and space for the twisting machine. Figure 2 and Figure 3 The reason why the yarn storage device is designed to be hollow and through-hole is that the yarn storage device and the two yarn winding devices fastened together actually constitute the core twisting component of the twisting device provided by this invention. Among the three components, only the yarn storage device rotates around itself, while the two yarn winding devices actually revolve around the yarn storage device. Therefore, whether guiding the raw material yarn to be twisted into the core twisting component or outputting the twisted raw material yarn outside the core twisting component or even outside the entire twisting device, allowing the raw material yarn to travel in a straight line through the hollow and through-hole interior of the yarn storage device, which does not participate in rotation, can avoid unnecessary revolution of the raw material yarn around the yarn storage device, thereby avoiding unnecessary air resistance and achieving energy savings in the twisting machine using the twisting device of this invention, as well as saving the volume occupied by the core twisting component and even the entire twisting device; moreover, Figure 2 and Figure 3 The exterior of the yarn storage device shown has been used to wind and collect the twisted raw material yarn, and two yarn winders rotate around it continuously in a 360-degree omnidirectional manner. Therefore, in this invention, the exterior of the yarn storage device can no longer provide a passageway for the raw material yarn; the interior of the yarn storage device must be hollowed out to create a smooth, low-resistance, straight passageway for the raw material yarn. Note that for the twisting device provided in this invention, refer to... Figure 2 and Figure 3The raw yarn input to the twisting device can either first pass through one of the two yarn winders, then be wound around the outer surface of the yarn storage device, and then unwound from the yarn storage device under the traction of the other yarn winder before being output to the core twisting assembly and even the entire twisting device through the hollow passage of the yarn storage device; or it can first enter the core twisting assembly from the hollow passage of the yarn storage device, then be drawn to one of the two yarn winders through the hollow passage of the yarn storage device and pass through it before being wound around the outer surface of the yarn storage device, and then unwound from the yarn storage device under the traction of the other yarn winder before being output to the core twisting assembly and even the entire twisting device through the other yarn winder. Furthermore, referring to all the accompanying drawings, in this invention, the two winding devices are fastened together, so their rotational speeds around the yarn storage device are the same. As in the first embodiment, the two winding shafts are fastened to the edge of a winding disc 105, forming a single unit with the disc. Therefore, the speed at which the two winding devices wind and collect the twisted raw material yarn onto the yarn storage device and unwind the raw material yarn from the yarn storage device are the same. Thus, there is no need to worry about the temporarily collected raw material yarn on the yarn storage device increasing indefinitely. Moreover, in this invention, referring to... Figure 2 The reason why the rotational speed of the yarn storage device, driven by the yarn storage device transmission mechanism, can be set to be different from the rotational speed of the two yarn winders driven by the yarn winder transmission mechanism is to control the number of turns of the raw material yarn temporarily wound and collected on the yarn storage device. That is, the difference in rotational speed between the yarn storage device and the two yarn winders is used to control the amount of raw material yarn wound and collected on the yarn storage device to maintain it at a suitable level. Furthermore, it should be noted that an important technical feature of this invention is... Figure 2 and Figure 3 As shown, the raw yarn located between the raw yarn input end of the twisting device and the raw yarn output end of the winding device that winds the raw yarn input to the twisting device onto the yarn storage device will bend under continuous tension. This is actually a necessary and sufficient condition for the twisting device provided by the present invention to perform the necessary twisting operation on the raw yarn. As mentioned above, almost all types of twisting machine equipment, including the most common doubling twister, include a "collecting and winding device" that actively pulls and collects the twisted multi-strand yarn output from the twisting device and then winds it into the final finished product, the yarn cone. Figure 2The upper part of the right view shows two opposing rotating rollers pulling the twisted yarn upwards. Therefore, a twisting machine using the twisting device provided by this invention must also include a collection and winding device that actively pulls and collects the raw material yarn after it has been twisted and output by the twisting device. This provides a continuous pulling force on the raw material yarn input to the twisting device. Under this continuous pulling force, the raw material yarn is clamped at the bend. Before being wound by the yarn winder to the yarn storage device, the clamped raw material yarn continuously revolves around the yarn storage device with the yarn winder, thus achieving the desired twisting operation. Of course, in this invention, when the rotational speed (i.e., angular velocity) of the yarn storage device is different from that of the two yarn winders, the yarn storage device, as a temporary intermediate collection point for the raw material yarn, also applies a continuous pulling force to the raw material yarn input to the twisting device, especially to the core twisting assembly. In addition to using the yarn winder, which continuously revolves around the yarn storage device, to twist the raw material yarn as described above, this invention can also use the yarn storage device to twist the raw material yarn input to the core twisting component and even the entire twisting device. (Reference) Figure 2 and Figure 3 As described above, the raw material yarn input to the core twisting component and even the twisting device can either first pass through any of the yarn winders and then be wound onto the yarn reservoir, or it can first pass through the hollow passage of the yarn reservoir and then be pulled to a selected yarn winder. In fact, in both cases, the raw material yarn input to the twisting device will be continuously pulled and bent and clamped when entering and exiting the hollow passage of the yarn reservoir, thus undergoing twisting operation as the yarn reservoir rotates. If... Figure 2 The raw yarn input to the twisting device is first passed through one of the yarn winders and then wound onto the yarn storage device. In this condition, the raw yarn unwound from the yarn storage device by another yarn winder and then passed through the hollow passage of the yarn storage device will inevitably bend when it enters the hollow passage. Since both yarn winders revolve around the yarn storage device, they cannot be located on the central axis of the hollow passage. Furthermore, under this condition, the twisted yarn output from the hollow passage of the yarn storage device will be subjected to continuous tension from the collecting and winding device of the twisting machine. Therefore, the portion of the raw yarn that bends into the hollow passage of the yarn storage device and is then output to the collecting and winding device of the twisting machine will definitely be clamped at the bend and twisted as the yarn storage device continues to rotate. For the first embodiment, as shown... Figure 2 The image shows the location. Figure 2The hollow yarn storage cylinder 104 in the right view extends through the interior to... Figure 2 The section of yarn between the pair of rollers representing the collecting and winding device in the upper right view will be twisted by the continuous rotation of the yarn storage cylinder 104, which represents the yarn storage device. It should also be noted that in this condition, when the raw material yarn is wound onto the yarn storage device from the first winding device, the raw material yarn will inevitably bend as it leaves the first winding device, and this bending occurs under continuous tension. This bending, occurring before the raw material yarn leaves the winding device and is wound onto the yarn storage device, allows the winding device to twist the raw material yarn through its revolution around the yarn storage device. For the first embodiment, this is as follows: Figure 2 As shown in the right view, the raw material yarn will undergo the following at the bend position away from the upper opening of the long winding beam 1051: Figure 2 The right view shows a bend and clamping at the bend, and as the long winding beam 1051 continues to rotate around the yarn storage cylinder 104 under the continuous drive of the winding disc 105, the opening at the upper end of the long winding beam 1051 and Figure 2 In the lower right view, the section of raw yarn between the pair of rollers representing the raw yarn input device of the twisting machine is twisted by the winding device represented by two long and short winding beams. For the raw yarn input to the twisting device, it is first input into the twisting device through the hollow interior of the yarn storage unit, see reference... Figure 3 As shown in the left view, since the two winding devices revolve around the yarn storage device in this invention, when the raw material yarn is drawn from the hollow passage of the yarn storage device to either winding device, it will inevitably bend at the outlet inside the hollow passage of the yarn storage device, such as... Figure 3 As shown in the left view, in the first embodiment, the raw material yarn is bent at the lower opening of the yarn storage cylinder 104. Since the subsequent yarn is not only continuously pulled by the collecting and winding device of the twisting machine, but also, as mentioned earlier, the difference in rotational angular velocity between the yarn storage device and the winding device generates a continuous pulling force on the raw material yarn inside the hollow passage of the yarn storage device, the raw material yarn pulled from the hollow passage of the yarn storage device to the winding device will be clamped at the bent portion at the outlet of the hollow passage of the yarn storage device. This causes the raw material yarn input to the twisting device to be twisted at the outlet of the hollow passage of the yarn storage device as the yarn storage device continues to rotate. For the first embodiment, as shown... Figure 3 The left view shows the location Figure 3In the upper left view, the section of raw material yarn between the raw material yarn input device, represented by a pair of opposing rotating rollers, and the lower opening of the yarn storage cylinder 104 will be twisted as the yarn storage cylinder 104 continues to rotate. It should also be noted that in this operating condition, when the raw material yarn is drawn from the hollow interior of the yarn storage device onto a selected winder, the raw material yarn will also bend on the selected winder, such as... Figure 3 As shown in the left view, the raw material yarn bends at the lower opening of the long winding beam 1051. Due to the continuous pulling of the collecting and winding device of the twisting machine and the continuous pulling force generated by the difference in rotational angular velocities between the yarn store and the winding device, the bending point of the raw material yarn on the selected winding device is clamped, thus allowing the raw material yarn to be twisted as the winding device continuously revolves around the yarn store. For the first embodiment, as shown... Figure 3 As shown in the left view, the raw material yarn input to the twisting device 1, upon exiting the lower opening of the yarn storage cylinder 104 and entering the lower opening of the long winding beam 1051, will be twisted by the yarn winder, represented by the long and short winding beams, as the long winding beam 1051 revolves around the yarn storage cylinder 104. In summary, as... Figure 2 and Figure 3 As shown, regardless of the different travel paths of the raw material yarn in the twisting device and the twisting machine using the twisting device, the twisting device provided by the present invention can twist the raw material yarn through the rotation of the yarn storage device and the revolution of the yarn winder. Especially when the rotational angular velocities of the yarn storage device and the yarn winder are different, the difference in the amount of twist applied to the raw material yarn by the two devices per unit time can offset any possible unwinding of the twisted yarn. This is one reason why the present invention includes a yarn storage device with a hollow, through-hole interior that can rotate continuously.

[0019] As an optimized implementation scheme of the basic technical solution of the present invention, such as Figure 2 and Figure 3 As shown, the yarn storage device is designed as a hollow, through-hole yarn storage cylinder 104, and the twisting device includes a yarn storage cylinder transmission mechanism 102 that drives the yarn storage cylinder to rotate continuously around its hollow, through-hole internal axis. Figure 2 and Figure 3The advantage of setting the yarn storage device as a long and thin cylindrical structure is that the long and thin cylindrical outer surface of the cylindrical structure is a shape that not only allows the raw material yarn to be easily wound around it multiple times for temporary collection, but also makes it easy to separate the winding position and the unwinding position of the raw material yarn with a certain distance to avoid unnecessary interference between the raw material yarn wound on the yarn storage device and the raw material yarn unwound from the yarn storage device.

[0020] As a preferred implementation scheme of the above-mentioned optimized implementation scheme, such as Figure 1 and Figure 2 As shown and referenced Figure 3 Both yarn winders are fastened to the edge of a hollow, through-hole yarn winding disc 105. The twisting device includes a yarn winding disc transmission mechanism 103 that drives the yarn winding disc 105 to rotate continuously around its hollow, through-hole interior. Driven by the yarn winding disc transmission mechanism 103, the yarn winding disc 105 rotates continuously around the rotation axis of the yarn storage cylinder 104, thus causing both yarn winders to rotate continuously around the yarn storage cylinder 104. The hollow, through-hole interior of the yarn winding disc 105 is as follows... Figure 2 and Figure 3 The diagram shows the path of the raw material yarn used to input the twisting device 1. (Reference) Figure 2 and Figure 3 By fastening both yarn winders to the edge of the same hollow, through-hole yarn winding disc 105, two purposes can be achieved: firstly, by driving a single yarn winding disc 105, both yarn winders can continuously rotate around the yarn storage device; secondly, the hollow interior of the yarn winding disc 105 can serve as a straight passageway for the raw material yarn entering and exiting the core twisting component, since both yarn winders will continuously revolve around the yarn storage device during operation. Figure 2 and Figure 3 If the yarn enters and exits the core twisting component of the twisting device provided by this invention directly through the yarn winder, it will inevitably cause unnecessary rotating air rings to be generated in the raw material yarn, thus increasing air resistance and energy consumption of the twisting machine using the twisting device. Because... Figure 2 As shown above, the yarn storage device continuously rotates around its hollow interior. In this embodiment, the rotation axis of the yarn winding disc coincides with the rotation axis of the yarn storage device. Given the circumferential symmetry of the yarn winding disc itself, the hollow interior of the yarn storage device and the hollow interior of the yarn winding disc... Figure 2 and Figure 3 This creates a running channel for the raw material yarn that coincides with the same straight line. This avoids unnecessary rotational changes that increase air resistance and energy consumption as the raw material yarn passes through the core twisting component and the entire twisting device. Note that in this embodiment, reference... Figure 2 and Figure 3 The raw material yarn can be either fed into the twisting device through the hollow interior of the yarn storage container (i.e., the yarn storage cylinder) and then output from the hollow interior of the winding disc, or fed into the twisting device through the hollow interior of the winding disc and then output from the hollow interior of the yarn storage container. When using the twisting device provided by this invention, a twisting machine can flexibly choose whether to feed the core twisting component from the hollow interior of the yarn storage container or the hollow interior of the winding disc during the actual implementation of multi-strand raw material yarn twisting or single-strand roving yarn twisting processes. Furthermore, it can rationally and dynamically modulate the rotation direction and speed of the yarn storage container drive mechanism and the winding disc drive mechanism. For a twisting machine using the twisting device provided by the present invention, before starting use, multiple or single strands of raw material yarn need to be drawn from the hollow interior of the yarn storage container or the winding disc into the twisting device. Then, the raw material yarn is manually wound around the outside of the yarn storage container a few times to complete the initialization of the yarn storage container. After that, it is pulled to the collecting and winding device of the twisting machine. Then, the twisting machine can be started to continuously perform twisting operations on multiple or single strands of raw material yarn and directly produce the finished product yarn cone in one step.

[0021] As a further optimized implementation scheme of the above preferred implementation scheme, such as Figures 1 to 3 As shown, the twisting device 1 includes two yarn winders, which are two hollow, through-hole yarn winding shafts of different lengths. The hollow interiors of the long yarn winding shaft 1051 and the short yarn winding shaft 1052 can both be used for the passage of the raw material yarn input into the twisting device 1. It should be noted that, firstly, the reason for designing the yarn winders as hollow and allowing the raw material yarn to pass through their hollow interiors in this embodiment is to simplify the function of the yarn winders in pulling and passing the raw material yarn. After all, compared to the simple drilling on a lathe or the one-step tube-drawing process on a broaching machine, fastening the components for pulling and passing the raw material yarn onto the yarn winder is redundant, time-consuming, and costly. Secondly, designing the two yarn winders as one long and one short helps to separate the winding and unwinding positions of the raw material yarn on the yarn storage device, avoiding unnecessary interference between the winding, collection, and unwinding of the raw material yarn on the yarn storage device.

[0022] As a preferred specific implementation scheme of the above-mentioned optimized implementation scheme, such as Figure 1 As shown and referenced Figure 3The yarn storage cylinder transmission mechanism 102 and the yarn winding disc transmission mechanism 103 are both driven by the same transmission shaft 101. Both are belt-driven transmission mechanisms, including a driving pulley, a driven pulley, and a transmission belt. The yarn storage cylinder transmission mechanism 102 and the yarn winding disc transmission mechanism 103 form a coaxial asynchronous transmission mechanism that drives the yarn storage cylinder 104 and the yarn winding disc 105 to rotate continuously at different speeds. Belt drive was chosen for the yarn storage cylinder transmission mechanism 102 and the yarn winding disc transmission mechanism 103 because of the stability and low failure rate of belt drive mechanisms. The advantage of using the same transmission shaft 101 to simultaneously drive two transmission mechanisms compared to using two separate motors to drive two transmission mechanisms is obvious. Figure 1 As shown and referenced Figure 2 In the first embodiment, the diameter of the driving wheel 1021 of the yarn storage cylinder transmission mechanism 102 is larger than the diameter of the driven wheel 1022, while the diameter of the driving wheel 1031 of the yarn winding disc transmission mechanism 103 is smaller than the diameter of the driven wheel 1032. Both transmission mechanisms are driven by the same transmission shaft 101, so the rotational angular velocity of the yarn storage cylinder 104 in the first embodiment is greater than the rotational angular velocity of the yarn winding disc 105 and the two yarn winding shafts fastened to it. Since they are both driven by the same transmission shaft 101, therefore... Figure 2 and Figure 3 The first embodiment shown includes a yarn storage cylinder 104 whose rotational direction is consistent with that of the two yarn-winding shafts. For example... Figure 2 and Figure 3 Regarding the raw material yarn input to the twisting device 1 provided by the present invention, since the yarn storage cylinder 104 and the long winding beam 1051 participating in twisting the raw material yarn in the twisting device 1 provided by the present invention perform rotational twisting in the same direction, the section of yarn between the yarn storage cylinder 104 and the long winding beam 1051 will definitely experience the situation where the previously applied twist is untwisted. However, under the synchronous drive of the coaxial asynchronous transmission mechanism in the first embodiment, the rotational speeds of the yarn storage cylinder 104 and the long winding beam 1051 are different. Therefore, even if there is untwisting between the two, the twist of the yarn ultimately output to the core twisting component and even the entire twisting device will not be completely untwisted. The number of untwisted twists on the yarn depends on the speed difference between the yarn storage device represented by the yarn storage cylinder 104 and the winding device represented by the long winding beam 1051 participating in twisting the raw material yarn. Taking the case where a raw material yarn in the first embodiment is first twisted by the winding device through a revolution, as an example, Figure 2 Right view and Figure 3As shown in the right view, since the direction of rotation of the long winding beam 1051, representing the yarn winder, is the same as that of the yarn storage cylinder 104, representing the yarn storage device, the simultaneous rotational twisting of the raw material yarn input to the twisting device 1 by both will inevitably result in untwisted twist. However, since the rotational speed of the yarn storage cylinder 104 in the first embodiment is greater than that of the long winding beam 1051 in the same direction, even if some of the twist generated by the rotational twisting of the raw material yarn by the long winding beam 1051 is neutralized by the subsequent rotation of the yarn storage cylinder 104 in the same direction, there will still be unneutralized and untwisted twist on the yarn that is finally output to the collecting and winding device of the twisting machine through the yarn storage cylinder 104. The final amount of twist depends on the difference between the rotational speeds of the yarn storage cylinder 104 and the long winding beam 1051 in the same direction. Therefore, the yarn output by the twisting device provided by the present invention, represented by the first embodiment, can be guaranteed to be subjected to truly effective rotary twisting and ultimately produce a sufficient number of true twists to meet the process requirements of the package yarn product.

[0023] Finally, refer to Figure 2 and Figure 3 The present invention also provides a twisting machine, which, like existing twisting machines such as doubling twisters and ring spinning machines, is used to twist multi-strand or single-strand raw material yarns and then wind them into finished yarn bobbins 5.
