Technical Field

[0001] The utility model relates to the technical field of twisting machines, in particular to a compacting structure of a twisting machine. Background Art

[0002] The twister is a mechanical equipment specially used in the field of yarn textile. Its main function is to twist the yarn to make it looser and more uniform, which is convenient for subsequent textile processing. The compression structure is an important component of the twister. Its main function is to fix the yarn and prevent it from moving or falling off during the twisting process, thereby ensuring the accuracy and stability of the twisting.

[0003] The clamping structure on the traditional twisting machine can adapt to yarns of different diameters and complete the fixing work by adjusting the spacing of the clamping parts on both sides. However, in actual operation, when yarns of different diameters need to be twisted, it faces a significant disadvantage. That is, after the yarn is fixed, in order to ensure the smooth progress of subsequent twisting work, it is often necessary to manually adjust the distance between each yarn. The traditional clamping structure does not have the function of adjusting the yarn spacing accordingly according to the change of yarn diameter. This undoubtedly increases the complexity and time cost of the operation, and also limits the improvement of production efficiency.

[0004] Furthermore, we disclose a compacting structure of a twisting machine to meet the practical demand that the existing technology does not have the capability to adjust the yarn spacing accordingly according to the change of yarn diameter. Utility Model Content

The upper ends of multiple upper pressure rods are fixedly connected to sliders, and the lower end of the lifting plate is provided with a rectangular groove, and the slider is slidably engaged and connected to the inside of the rectangular groove.

[0009] Preferably, the pitch adjustment module includes a roller rotatably connected to the lower end of the bracket, the outer wall of the roller is provided with a spiral groove having the same number as the lower pressure rod, the lower end of the lower pressure rod is slidably connected to the inside of the spiral groove, and the rotation directions of the multiple spiral grooves on both sides of the middle are opposite, and the closer to the middle on the same side, the shorter the pitch of the spiral groove.

[0014] Beneficial effects of the utility model:

[0015] The compression structure of the stranding machine uses a clamping module arranged inside the bracket to accurately limit the yarn position. The clamping module consists of an upper pressure rod and a lower pressure rod.

More importantly, the distance adjustment module arranged at the lower end of the structure can be driven by the lifting action of the lifting plate, so as to flexibly adjust the distance between each yarn according to the diameter of the yarn to meet different production needs.

[0016] The above components improve the accuracy and stability of yarn compression. The clamping action of the upper and lower pressure rods ensures that the position of the yarn is fixed during the processing, avoiding production quality problems caused by yarn deviation or looseness, and enhancing production flexibility. The introduction of the distance adjustment module allows the yarn spacing to be quickly adjusted according to the diameter of the yarn, improving the adaptability and production efficiency of the equipment.

[0027] like Figures 1 to 5 As shown, a compression structure of a stranding machine includes a bracket 1 installed on the stranding machine, a clamping module is arranged inside the bracket 1, the clamping module is used to limit the position of the yarn, the clamping module includes a plurality of upper pressure rods 12 and a lower pressure rod 9, the number of the upper pressure rods 12 and the lower pressure rod 9 is the same, both sides of the upper end of the inner wall of the bracket 1 are provided with a slide groove 15, a lifting plate 2 is slidably connected between the two slide grooves 15, the plurality of upper pressure rods 12 are slidably connected to the lower end of the lifting plate 2, the inner lower end of the bracket 1 is fixedly connected to a guide plate 4, the middle part of the guide plate 4 is provided with a guide groove 8, the plurality of lower pressure rods 9 are slidably connected to the inside of the guide groove 8, the lower end of the bracket 1 is provided with a distance adjustment module, the distance adjustment module is used to adjust the distance between each yarn, and the distance adjustment module is driven by the lifting of the lifting plate 2;

[0028] This compression structure improves the accuracy and stability of yarn compression. Through the clamping action of the upper and lower pressure rods, it ensures that the position of the yarn is fixed during the processing, avoids production quality problems caused by yarn deviation or looseness, and enhances production flexibility. The introduction of the spacing adjustment module allows the yarn spacing to be quickly adjusted according to the diameter of the yarn, improving the adaptability and production efficiency of the equipment.

[0029] Further, such as Figure 1 、 Figure 2 、 Figure 5As shown, a card plate 20 is fixedly connected to the middle of the upper end surface of the lifting plate 2, and the inner upper end of the card plate 20 is engaged and rotatably connected to the screw rod 3, the upper end of the screw rod 3 passes through the bracket 1 and is threadedly connected to the bracket 1, and a handle is provided on the upper end of the screw rod 3. The upper end of the lower pressure rod 9 is fixedly connected to the lower pressure head 14, and the lower end of the upper pressure rod 12 is fixedly connected to the upper pressure head 11. The opposing surfaces of the lower pressure head 14 and the upper pressure head 11 are both arc-shaped and have a groove 13 in the middle. The upper ends of the multiple upper pressure rods 12 are fixedly connected to the slider 21, and the lower end of the lifting plate 2 is provided with a rectangular groove 22. The slider 21 is slidably engaged and connected to the inside of the rectangular groove 22;

[0030] By turning the handle at the upper end of the screw rod 3, the screw rod 3 starts to rotate and move up and down due to its threaded connection with the bracket 1, and the upper end of the screw rod 3 is engaged and rotatably connected with the inner part of the card plate 20, and the card plate 20 is fixedly connected to the middle part of the upper end surface of the lifting plate 2. Therefore, the rotation and lifting movement of the screw rod 3 will directly drive the lifting plate 2 to slide up and down along the slide groove 15 on the inner wall of the bracket 1. As the lifting plate 2 rises and falls, the multiple upper pressure rods 12 fixed at the upper end thereof also move synchronously. The lower ends of these upper pressure rods 12 are fixed with upper pressure heads 11. The opposite surface of 11 is arc-shaped and a groove 13 is opened in the middle. This design enables the upper pressure head 11 to fit closely to the surface of the yarn and provide a stable pressing force during the lifting process. On the other hand, the lower pressure rod 9 contacts the lower part of the yarn through the lower pressure head 14 at its upper end. The design of the lower pressure head 14 is also arc-shaped and a groove 13 is opened in the middle to ensure a close fit with the yarn. The lower pressure rod 9 can maintain a stable motion trajectory during the lifting process, and form a synergistic effect with the upper pressure rod 12 to jointly achieve stable compression of the yarn.

[0031] Further, such as Figures 1 to 4 As shown, the pitch adjustment module includes a roller 5 rotatably connected to the lower end of the bracket 1. The outer wall of the roller 5 is provided with a spiral groove 6 of the same number as the lower pressure rod 9. The lower end of the lower pressure rod 9 is slidably connected to the inside of the spiral groove 6. The rotation directions of the multiple spiral grooves 6 on both sides of the middle are opposite, and the closer the spiral groove 6 on the same side is to the middle, the shorter the pitch. The pitch adjustment module also includes a connecting rod 19. The connecting rod 19 is U-shaped. One end of the lifting plate 2 passes through the bracket 1 and is fixedly connected to the connecting rod 19. The lower end of one side of the inner wall of the connecting rod 19 is evenly spaced and fixedly connected to multiple The lower end of the connecting rod 19 is meshed with the gear 18 through the tooth block, and the middle part of the end face of the gear 18 close to the bracket 1 is fixedly connected to the rotating rod 17. The end of the rotating rod 17 away from the gear 18 passes through the bracket 1 and is fixedly connected to the roller 5. The end face of the bracket 1 on one side of the connecting rod 19 is fixedly connected to the sliding sleeve 16. The middle part of the connecting rod 19 is slidably connected to the inside of the sliding sleeve 16. The upper end face of the lower pressure head 14 is fixedly connected to the sliding rod 10. The upper end of the sliding rod 10 passes through the upper pressure head 11 and is slidably connected to the upper pressure head 11.

[0032] The outer wall of the roller 5 is designed with spiral grooves 6 with the same number as the lower pressure rod 9, and the lower end of each lower pressure rod 9 is slidably connected to the inside of these spiral grooves 6. This design enables the spiral grooves 6 to drive the lower pressure rod 9 to move horizontally along its trajectory when the roller 5 rotates, thereby realizing the function of adjusting the yarn spacing. In particular, the multiple spiral grooves 6 on both sides of the middle rotate in opposite directions, which ensures that when the roller 5 rotates, the lower pressure rods 9 on both sides will move in opposite directions, thereby increasing or decreasing the distance between the yarns. At the same time, the closer the spiral grooves 6 on the same side are to the middle, the shorter the pitch is. This design makes the change in yarn spacing more uniform and delicate during the adjustment process, which can meet more sophisticated production needs. Another key component of the pitch adjustment module is the connecting rod 19, which is fixedly connected to one end of the lifting plate 2 and moves with the lifting and lowering of the lifting plate 2. A plurality of tooth blocks are evenly spaced and fixed at the lower end of one side of the inner wall of the connecting rod 19. These tooth blocks are meshed with the gear 18. When the connecting rod 19 rises or falls with the lifting plate 2, the tooth blocks will drive the gear 18 to rotate, and then drive the roller 5 to rotate through the rotating rod 17. In this way, the lifting action of the lifting plate 2 is converted into the rotation action of the roller 5, thereby realizing the adjustment of the position of the lower pressure rod 9, and the lower pressure rod 9 drives the lower pressure head 14 to move synchronously. The movement of the lower pressure head 14 can drive the upper pressure head 11 and the upper pressure rod 12 to move synchronously through the sliding rod 10, and the upper pressure rod 12 is slidably connected to the rectangular groove 22 inside the lifting plate 2 through the slider 21, ensuring the stability of the synchronous movement of the upper pressure head 11 and the upper pressure rod 12. In addition, the middle part of the connecting rod 19 is slidably connected to the inside of the sliding sleeve 16 on one side of the bracket 1, which ensures the stability of the connecting rod 19 during the movement.

[0033] Further, such as Figure 3 As shown, the inner walls of the bracket 1 are fixedly connected to the lower ends of the two sides of the guide plate 4 with tensioning rods 7. The yarn first passes through the lower end of the tensioning rod 7 and then enters the groove 13, ensuring that the yarn can contact the surface of the groove 13 to the greatest extent, thereby improving the stability of the yarn moving in the groove 13.
