Description

TECHNICAL FIELD

[0001] The utility model belongs to textile equipment technical field, concretely relates to a tension combination device for twisting machine. BACKGROUND

[0002] In the twisting machine, bobbin winder and other equipment of the textile industry, yarn tension control directly affects the yarn quality and production efficiency. The current mainstream tension control scheme in the domestic market has significant limitations:

[0003] The traditional mechanical tensioner only provides single tension through fixed mechanical structure such as gate spring leaf or porcelain ring friction, and cannot be finely adjusted. The actual measurement data shows that the inter-spindle tension difference is as high as ±15% or more, and it is only suitable for low-count yarn, regenerated fibers and other materials that are not sensitive to tension, such as carded cotton yarn, low-quality polyester. When used for medium and high-count yarn, problems such as uneven tension of the bobbin, increased breakage rate, etc. may occur, which cannot meet the needs of the medium market.

[0004] Electronic servo control provides real-time feedback through tension sensors, drives the overfeed roller to dynamically adjust the yarn speed, and the inter-spindle tension difference can be controlled within ±2%, which is suitable for high-count yarn, special fibers such as spandex core yarn and aramid. However, the cost of a single spindle is 5-8 times that of the traditional scheme (including servo motor, controller and sensor), and it requires a complex electrical system, resulting in a sharp rise in the price of the entire machine. According to industry research, more than 80% of the conventional yarn winding scenes in the domestic market require only ±5% tension accuracy, and this scheme has obvious functional redundancy and cost waste.

[0005] The current medium market urgently needs a tension control scheme that balances accuracy and cost. The traditional mechanical scheme is gradually eliminated due to its lack of precision, while the electronic scheme is difficult to popularize due to its low cost performance. In addition, existing schemes generally have complex maintenance issues, such as electronic components being easily affected by temperature and humidity, poor adaptability, such as being unable to accommodate different yarn diameters, and difficulty in meeting the core needs of small and medium-sized textile enterprises for stability, economy and easy maintenance.

[0006] To solve the above problems, a tension combination device for twisting machine with high cost performance suitable for the market is needed to fill the technical gap in the medium market and meet the needs of large-scale production of conventional yarns such as cotton, polyester and blended yarns. This device retains the flexibility of manual adjustment and effectively solves the problems of current tension control schemes on the market, and meets the actual production needs. CONTENT OF THE UTILITY MODEL

[0007] Therefore, the utility model provides a tension combination device for twisting machine. The tension combination device has a reasonable structure, is simple and convenient to operate, and has high cost performance. It realizes the winding of different yarns and different tensions on the bobbin winder.

[0008] To achieve the above object, the technical scheme of the utility model is as follows:

[0009] A tension combination device for a twisting machine, a feedback wheel assembly, a gate type tensioner and a tension stabilizing assembly are sequentially installed on an external device from top to bottom.

[0010] The feedback wheel assembly comprises a second mounting seat, a feedback wheel seat, a tension feedback wheel, a sliding plate, a porcelain piece, a tension control rod and a protective sleeve, the second mounting seat is fixed on the external device, and the feedback wheel seat is fixed on the second mounting seat; the sliding plate is installed on the feedback wheel seat, the porcelain piece is fixed on the sliding plate, and the protective sleeve is arranged at the two ends of the tension control rod and fixed on the lower part of the second mounting seat. The tension of the yarn at the feedback wheel assembly can be accurately adjusted through the height adjustment of the sliding plate and the position adjustment of the tension control rod. Different yarn materials and twisting processes require different tensions, and the feedback wheel assembly can be flexibly adjusted according to the actual situation to ensure that the yarn maintains appropriate tension in the subsequent processing process, avoids yarn breakage caused by excessive tension, or uneven twisting caused by insufficient tension and other problems. The porcelain piece is fixed on the sliding plate, and the surface of the porcelain piece is smooth, which can reduce the friction between the yarn and the components, avoid damage to the yarn and ensure the quality of the yarn. At the same time, the protective sleeves at the two ends of the tension control rod can also play a protective role to prevent the debris generated by the friction between the tension control rod and the second mounting seat from polluting or damaging the yarn.

[0011] The tension stabilizing assembly comprises a first mounting seat, a position porcelain piece, a first sleeve, a second sleeve and a silk passing porcelain piece, the first mounting seat is fixed on the external device, the silk passing porcelain pieces are arranged on the upper and lower sides of the first mounting seat respectively, the second sleeve, the position porcelain piece and the first sleeve are sequentially abutted and fixed on one side of the first mounting seat, and the second sleeve is closest to the first mounting seat. The first sleeve, the second sleeve and the position porcelain piece jointly provide a stable support and constraint environment for the yarn. When the yarn tension changes slightly, these components can buffer and adjust the yarn tension to a certain extent through their own structure and interaction, assist the entire device in stabilizing the yarn tension and ensure the consistency of the twisting quality. The surface of the silk passing porcelain piece is smooth, and the yarn can effectively reduce the friction between the yarn and the components when passing through the silk passing porcelain piece, prevent the yarn from being damaged due to friction, and also reduce the heat generated due to friction, thereby avoiding adverse effects on the performance of the yarn.

[0012] In a structure that can optimize the foregoing scheme, a gas ring device is further included, which is fixed on the external device, below the tension stabilizing assembly, and in a straight line with the feedback wheel assembly, the door-type tensioner, and the tension stabilizing assembly. The gas ring device controls the shape of the gas ring during the twisting process by restraining and guiding the yarn. During the twisting process, the yarn forms a gas ring after being output from components such as spindles. The gas ring device can keep the gas ring in a suitable shape and range. For example, the gas ring control ring in the ring twisting device, the gas ring ring restrains the gas ring yarn at the lower 1 / 3 of the dynamic range during the twisting process. At the same time, the size and stability of the gas ring directly affect the tension of the yarn. The gas ring device controls the gas ring to avoid large fluctuations in yarn tension caused by excessively large or small gas rings, thereby making the yarn tension more stable.

[0013] In a structure that can optimize the foregoing scheme, a long slot hole is opened on the slide plate, and the slide plate is installed on the feedback wheel seat through the long slot hole. The slide plate can be adjusted in height up and down along the long slot hole. On the one hand, different specifications of yarns have different requirements for tension feedback and control methods during twisting. By adjusting the height of the slide plate, the positions of components such as porcelain and tension feedback wheels can be changed, and the contact angle and positional relationship of the yarn with these components can be adjusted to meet the characteristics of various yarns and specific process requirements, and to ensure that the yarn is twisted under suitable tension. On the other hand, the change in the height of the slide plate will affect the perception and feedback degree of the tension feedback wheel to the yarn tension, which can more sensitively capture the changes in the yarn tension and transmit signals, facilitating timely adjustment of the tension, improving the accuracy and timeliness of the feedback, and ensuring the stability of the twisting quality. In addition, during the installation and debugging of the equipment and daily maintenance, the height of the slide plate can be conveniently adjusted by the staff according to the actual situation, for example, during the installation of new yarn varieties or after the equipment is overhauled, it can be quickly adjusted to the appropriate position, so that the equipment can quickly reach the best working state, effectively reducing the debugging time and cost, and improving the efficiency of the equipment operation.

[0014] In a structure that optimizes the aforementioned solution, the lower part of the mounting base two has an elongated slot, and the tension control rod is fixed to the slot with protective bushings at both ends. The tension control rod can be adjusted back and forth along the elongated slot. During the twisting process, given that yarns at different stages and with different characteristics have different tension requirements, the tension control rod can be adjusted back and forth along the elongated slot at the lower part of the mounting base two. The operator can then precisely change the contact position and angle between the yarn and the tension control rod. For example, when the yarn tension needs to be increased, it can be adjusted to a position closer to the yarn's running path to increase resistance and raise the tension; conversely, it can be adjusted to a position further away from the path to reduce resistance and lower the tension, thus achieving precise control of the yarn tension and meeting the complex and varied twisting process requirements. Simultaneously, different materials and thicknesses of yarn have different tension sensitivities and suitable tension values. Flexible adjustment of the tension control rod's position can adapt to various yarn characteristics. For example, for fine, soft, and easily broken yarns, the contact force can be reduced to prevent breakage, while for harder yarns requiring high twist, the contact force can be increased to ensure the twisting effect, thus broadening the applicability of the twisting machine to different yarns. Furthermore, during the installation and commissioning phase of the twisting machine, technicians can easily adjust the tension control bar based on the equipment's operating status and the expected yarn tension effect, quickly determining the optimal position and shortening the commissioning cycle. In routine maintenance, if abnormal yarn tension occurs, its position can be adjusted promptly for initial troubleshooting and adjustment, eliminating the need for large-scale equipment disassembly, thus improving maintenance efficiency, reducing costs, and ensuring stable equipment operation. Moreover, the protective bushings at both ends of the tension control bar prevent direct friction between the bar and the long slot, extending its service life and that of the mounting base, reducing equipment maintenance frequency. They also prevent damage to the yarn from debris and burrs generated during friction, ensuring that yarn quality and appearance remain unaffected and guaranteeing a smooth twisting process.

[0015] In a structure that optimizes the aforementioned scheme, a counterweight is installed on the left side of the gantry tensioner. The gantry tensioner is equipped with four different sizes and weights of counterweights for adjusting varying tensions. During the twisting process, the yarn requires appropriate tension at each stage due to factors such as yarn material, process, and equipment operating speed. By installing counterweights of different sizes and weights on the left side of the gantry tensioner, yarn tension can be flexibly adjusted: light weights prevent breakage of fine, soft yarns, while heavy weights ensure tight and uniform twisting of coarse, strong yarns, meeting diverse production needs. This structure facilitates the addition or removal of weights; operators can easily replace or add weights according to process requirements without the need for complex tools and equipment disassembly, significantly saving time and labor costs, improving production efficiency, and responding promptly to tension changes, ensuring the continuity and stability of the twisting process. Simultaneously, the combination of the gantry tensioner and different counterweights allows for precise tension control, avoiding problems such as uneven twist, loose yarn, and yarn breakage, resulting in high-quality, standard-compliant twisted yarn products, improving product qualification rate and market competitiveness.

[0016] In a structure that can optimize the foregoing scheme, the door-type tensioner is provided with a locking screw. During the operation of the twisting machine, continuous vibration and shaking will occur. If the components of the door-type tensioner are not firmly connected, the tension setting that has been adjusted may change due to the vibration. The locking screw can effectively prevent the connection part from loosening, ensure that the tension adjustment mechanism is always in the set position, and make the yarn continuously receive stable and process-required tension during the twisting process. For example, in the twisting operation of long-time and high-frequency operation, the ordinary screw connection may gradually loosen, causing the tension to be large and small, affecting the twisting quality, and the locking screw can avoid such situations and maintain stable tension.

[0017] In a structure that can optimize the foregoing scheme, the length of the first sleeve is greater than the length of the second sleeve. The first sleeve outside the position porcelain is longer than the first mounting seat. The longer first sleeve can provide a relatively longer stable guide path for the yarn. When the yarn enters the tension stabilizing assembly from the outside, the first sleeve can effectively support and guide the yarn in the initial stage, making the yarn smoothly approach the tension stabilizing assembly along the predetermined direction, greatly reducing the shaking and deviation of the yarn during the guide process, and assisting the yarn to accurately enter its working area.

[0018] In a structure that can optimize the foregoing scheme, the first mounting seat is provided with a plurality of threaded holes on one side. Preferably, there are three threaded holes. By installing the second sleeve, the position porcelain, and the first sleeve in different threaded holes, the position of the position porcelain can be adjusted. Different yarns have different characteristics, and adjusting the position porcelain can adapt to their thickness, texture, etc., optimize the running track, and ensure the twisting quality. The position porcelain also affects the stress of the yarn in the tension stabilizing assembly, and accurate adjustment can make the tension more uniform and stable, cooperate with other components to buffer the tension fluctuation, and reduce the twisting irregularity. Moreover, adjusting the position porcelain through the threaded holes is convenient and fast, without the need to modify the equipment, it can meet the production needs of different batches and specifications of yarns, improve the universality and flexibility of the equipment, reduce the cost, and improve the efficiency.

[0019] In a structure that can optimize the foregoing scheme, a functional plate is further included, and the feedback wheel assembly, the door-type tensioner, the tension stabilizing assembly, and the air loop device are arranged on the functional plate, which is fixed to the external equipment. The functional plate serves as an integrated platform, greatly simplifying the installation process. The installer does not need to separately position and install each component. Instead, the installer only needs to fix the functional plate as a whole to the external equipment, thereby reducing the installation adjustment steps, saving time and labor costs, and improving the installation efficiency. The functional plate also facilitates overall positioning. Since the functional plate is pre-designed with accurate installation dimensions and positioning holes, the installer can quickly and accurately install it at the appropriate position according to the requirements of the external equipment, thereby ensuring the relative position accuracy of the components and avoiding unreasonable overall layout caused by installation errors of individual components. When a certain component needs to be adjusted, the functional plate also provides convenience. Since the components are installed on the functional plate, the installer can directly operate on the plate, and the adjustment process is independent and convenient. For example, when the height of the slide plate in the feedback wheel assembly needs to be adjusted, the installer does not need to worry about interfering with other components, thereby improving the efficiency of equipment maintenance and debugging. When the equipment is upgraded or part of the components is replaced, the advantage is more prominent. Only the functional plate needs to be disassembled, and the components on the plate can be conveniently replaced or upgraded. After that, the functional plate can be reinstalled, thereby avoiding large-scale modification of the external equipment, reducing the upgrading difficulty and cost, and reducing the installation risk.

[0020] In a structure that can optimize the foregoing scheme, a speed feedback point is arranged in the feedback wheel seat. The tension feedback wheel and the speed feedback point can monitor the tension and speed of the yarn in real time and feed back the information to the control system. The control system can timely adjust the working parameters of other related components according to the feedback information, thereby realizing accurate control of the yarn tension in the entire twisting process and improving the twisting quality.

[0021] In a structure that can optimize the foregoing scheme, an operation panel is further included, which is arranged above the side surface of the functional plate and on the right side of the feedback wheel assembly. The operation panel is arranged above the side surface of the functional plate and at a height that is within the range of the natural line of sight of the standing operator and is easy to operate with the arms. This design height is in line with the ergonomic principle. The operator can conveniently check the panel information and operate without greatly bending over, looking up, or excessively stretching the body, thereby greatly reducing the fatigue caused by excessive stretching or twisting of the body, allowing comfortable operation for a long time, and effectively improving the work efficiency. At the same time, this reasonable position layout enables the operator to focus on the running state of the equipment when operating, thereby avoiding the distraction of attention to the key parts of the equipment due to the poor position of the operation panel, effectively ensuring the operation safety. Moreover, in the case of an emergency, the convenient operation position enables the operator to quickly press the emergency stop button or take other emergency measures on the operation panel, thereby further improving the safety and reliability of the equipment operation.

[0022] Compared with the prior art, the tension combination device for the twisting machine has the following significant advantages in multiple aspects through the innovative structural design:

[0023] 1. The combination of door-type tensioner and feedback wheel controls the tension, the structure is simplified, the cost performance is greatly improved, the tension control accuracy and the cost are balanced, and the middle-end market demand is met. The function board acts as an integrated platform, greatly simplifies the installation process, reduces the installation adjustment process, saves time and labor cost. Its accurate overall positioning ensures the accurate relative position of each component, convenient component adjustment, upgrading and replacement, reduces the upgrading difficulty and cost, and reduces the installation risk.

[0024] 2. The tension feedback wheel is made of nylon material and is formed by mold opening, has good wear resistance and uniform size, effectively ensures the consistency of tension between spindles, and significantly improves the stability of yarn quality, laying a foundation for high-quality twisted yarn.

[0025] 3. The position porcelain and the tension control rod can change the yarn stress by adjusting the installation position, adapt to the characteristics of various yarns, optimize the running track, and ensure the quality of twisted yarn. The shaft sleeve (shaft sleeve one) outside the position porcelain is longer than the mounting seat one, which provides a stable yarn guide path, reduces the shaking deviation, prevents being hooked by the mounting seat one, and maintains the yarn winding quality. At the same time, the protective shaft sleeve at both ends of the tension control rod not only prevents it from being damaged by friction with the long slot hole of the mounting seat two, prolongs the service life and reduces the maintenance frequency, but also avoids the damage of yarn caused by friction.

[0026] 4. The tension feedback wheel and the speed feedback point monitor the yarn tension and speed in real time, feed back the information to the control system, so that the system can timely control the spindle speed, ensure the speed matching of the yarn guide process, avoid the damage of the yarn, and realize the accurate control of the yarn tension in the whole process of twisted yarn.

[0027] 5. The door-type tensioner is equipped with a locking screw, which effectively prevents the connection part from loosening and maintains the tension stability. The counterweight pendant is placed on the left side of the door-type tensioner, which is convenient for increasing or decreasing and easy to operate. The operation panel is located above the side of the function board and to the right of the feedback wheel assembly, which is in line with the ergonomics, convenient for operators to check information and operation, reduces fatigue, and improves work efficiency. At the same time, it is convenient for operators to pay attention to the running state of the equipment, ensures the operation safety, can take emergency measures quickly in emergency, and enhances the safety and reliability of the equipment operation.

[0028] 6. The air loop device arranged below the function board can effectively control the tension fluctuation of the yarn during unwinding. By restraining and guiding the yarn, the air loop is maintained in a suitable shape and range, avoiding the yarn tension fluctuation caused by abnormal air loop, and further stabilizing the yarn tension.

[0044] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0045] As Figure 1As shown, the tension combination device for the twisting machine is prepared first with a functional plate 2 of a size suitable for the external equipment of the twisting machine and pre-designed with accurate installation size and positioning hole. After determining the appropriate installation position on the external equipment of the twisting machine, the functional plate 2 is firmly fixed on the rack 1 of the external twisting machine equipment through connecting members such as bolts, ensuring stable installation and providing a stable foundation for the subsequent component installation. Then the feedback wheel assembly installation is carried out: the mounting seat two 9 is fixed on the corresponding position of the functional plate 2 by welding or high-strength bolt connection, ensuring that the mounting seat two 9 is firmly installed and will not shift during equipment operation; in the long slot hole at the lower part of the mounting seat two 9, the tension control rod 14 provided with protective shaft sleeves 15 at both ends is inserted and fixed, so that it can be adjusted smoothly back and forth along the long slot hole; then the feedback wheel seat 10 is fixed on the mounting seat two 9, and the speed feedback point 24 is installed in the feedback wheel seat 10; the sliding plate 12 with a long slot hole is installed on the feedback wheel seat 10 through the long slot hole by bolts, allowing the sliding plate 12 to be adjusted flexibly up and down along the long slot hole, and the porcelain piece 13 is fixed on the sliding plate 12; finally, the tension feedback wheel 11 is installed at the appropriate position of the feedback wheel seat 10, ensuring that the components of the feedback wheel assembly are connected tightly and can be adjusted flexibly according to the design requirements. Then the door-type tensioner installation is carried out: the door-type tensioner 7 is fixed on the functional plate 2 at the appropriate position below the feedback wheel assembly by welding or bolt connection, and on the left side of the door-type tensioner 7, a weight hanging drop of appropriate specification and weight is selected and installed according to the expected use requirements and is ensured to be firm, and anti-loose screws 23 are installed at each connecting part of the door-type tensioner 7 to prevent the components from loosening due to vibration during equipment operation. Then the tension stabilizing component installation is carried out: the mounting seat one 16 is fixed on the functional plate 2 and below the door-type tensioner 7, and in the threaded hole on one side of the mounting seat one 16, the shaft sleeve two 19, the position porcelain piece 17 and the shaft sleeve one 18 are installed in sequence according to the characteristics of the yarn and the process requirements, ensuring that the three are tightly abutted, and the over-yarn porcelain piece 20 is installed on the upper and lower sides of the mounting seat one 16, ensuring that the over-yarn porcelain piece 20 is installed firmly and accurately positioned, facilitating smooth passage of the yarn. Then the air ring device installation is carried out: the air ring device 6 is fixed on the functional plate 2 at a position below the tension stabilizing component by welding or bolt connection, so that the air ring device 6 is in a straight line with the feedback wheel assembly, the door-type tensioner 7 and the tension stabilizing component, ensuring that the air ring device 6 is installed accurately and can effectively constrain and guide the yarn. Finally, the operation panel installation is carried out: the operation panel 8 is installed on the upper side of the functional plate 2 and the right side of the feedback wheel assembly at the appropriate position by connecting members such as bolts, ensuring that the installation height of the operation panel 8 meets the ergonomic principles, facilitating the operator to view information and operate.

[0046] In particular, the device is two groups, symmetrically installed on both sides of the rack 1.

[0047] The twisting machine uses the tension combination device to work, and each part cooperates with each other. Through the guidance, tension adjustment and feedback of the yarn, the yarn maintains appropriate tension during the twisting process, and high-quality twisting operation is realized. The specific working principle is as follows:

[0048] 1. Yarn starting and initial guiding: the yarn is drawn out from the yarn cake 25 at the lower part of the twisting machine and moves upward. The balloon device 6 plays the first role, which can prevent the yarn from forming a too large balloon during the upward movement through a specific structure. Because a too large balloon is easy to cause the yarn to entangle or the tension to be unstable, the balloon device can ensure that the yarn enters the subsequent components in a relatively stable state, providing a good start for the subsequent process.

[0049] 2. Initial action of tension stabilizing assembly: the yarn enters the tension stabilizing assembly, and the position porcelain 17 inside the assembly contacts and cooperates with the yarn. The installation seat 16 on one side is provided with a plurality of threaded holes, which can adjust the position of the position porcelain 17 to adapt to different characteristics of the yarn. For example, for thicker yarn, the position porcelain 17 can be adjusted to a looser position to prevent excessive extrusion; for soft and easy-to-entangle yarn, the position porcelain 17 is adjusted to make the yarn run more smoothly. At the same time, the yarn passes in and out through the upper and lower silk passing porcelain 20, and the smooth surface of the silk passing porcelain 20 effectively reduces the friction between the yarn and the assembly, ensuring the smooth running of the yarn and making the yarn enter the next component in a relatively stable state.

[0050] 3. Precise adjustment of door type tensioner: then, the yarn enters the door type tensioner 7. The door type tensioner 7 is provided with a counterweight pendant 22 on the left side, and is equipped with four counterweight pendants of different specifications and weights. During the twisting process, due to factors such as yarn material, twisting process and equipment running speed, the yarn needs appropriate tension at each stage. The operator can select counterweight pendants of different specifications and weights to install on the left side of the door type tensioner according to the actual situation, and flexibly change the tension applied to the yarn. For example, for fine and soft yarn, a lighter counterweight pendant is selected to avoid yarn breakage due to excessive tension; for thick and strong yarn, a heavier counterweight pendant is selected to ensure that the yarn obtains sufficient tension to realize close and uniform twisting, thereby meeting the diversified production needs and precisely controlling the tension of the yarn.

[0051] 4、Feedback wheel assembly monitoring and fine adjustment: the yarn after being adjusted by the door type tensioner 7 enters the feedback wheel assembly. In the feedback wheel assembly, the yarn first contacts the tension control rod 14, the tension control rod 14 is provided with a protective sleeve 15 at both ends and is fixed on the long slot hole in the lower part of the mounting seat two 9, and can be adjusted forward and backward along the long slot hole. The operator can preliminarily fine tune the yarn tension by adjusting the position of the tension control rod 14 to change the contact position and angle of the yarn. Then, the yarn contacts the tension feedback wheel 11, the tension feedback wheel 11 converts the real-time tension change of the yarn into a signal and transmits it to the control system or the operator, so as to timely understand the yarn tension condition. Finally, the yarn passes out of the feedback wheel assembly after contacting the porcelain piece 13. The feedback wheel assembly realizes real-time monitoring and preliminary fine adjustment of the yarn tension, provides continuous data support for the whole tension adjustment system, and ensures that the yarn tension is always in a suitable range.

[0052] 5、Speed feedback and speed adjustment: the speed feedback point 24 monitors the movement speed of the yarn in real time. When it is found that the yarn speed is too fast or too slow, the speed signal will be fed back to the controller. After receiving the signal, the controller adjusts the speed of the spindle 4 to stabilize the yarn tension. If the yarn speed is too fast, the speed of the spindle 4 is reduced, so that the winding speed of the yarn matches the tension adjustment speed of each component, avoiding problems such as loose line caused by too small tension due to too fast speed; if the yarn speed is too slow, the speed of the spindle 4 is increased to prevent the yarn from being broken due to too large tension caused by too slow speed. Through this closed-loop control mode, the stability of the yarn tension in the whole twisting process is further ensured.

[0053] 6、Yarn winding and forming: after the accurate control and stable adjustment of the yarn tension by the above components, the yarn passes through the guide head 3 fixed at the top of the guide rod 21. The guide rod 21 is installed in the functional plate 2 and can move up and down, driving the guide head 3 to move up and down synchronously, so as to guide the yarn to be wound on the aluminum bobbin 5 on the high-speed rotating spindle 4 in a specific path and mode. The spindle 4 is installed on the functional plate 2, and the aluminum bobbin 5 is sleeved on the spindle 4 and rotates at high speed with the spindle, completing the twisting process and producing twisted yarn products meeting the quality standards.

[0054] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
