Description

Technical Field

[0001] This invention relates to the field of twisting machine technology, specifically a twisting machine for semi-worsted cool-feeling fiber cashmere blended yarn. Background Technology

[0002] Cashmere fabric is soft, warm, and elastic, but its lack of cooling sensation has long been a concern for many users. Therefore, achieving rapid heat conduction has received considerable attention. Bamboo fiber is a cellulose fiber extracted from naturally grown bamboo. It possesses excellent breathability, instant water absorption, strong abrasion resistance, and good dyeability, and also has natural antibacterial, bacteriostatic, mite-repellent, deodorizing, and UV-resistant properties.

[0003] The manufacturing process of semi-worsted bamboo fiber cashmere blended products includes the following steps: Step 1: Cashmere and bamboo fiber are evenly mixed on a cotton picker in a specified ratio; Step 2: The parameters of various fiber processing equipment are adjusted and set; Step 3: Two drawing processes are used to prevent the bamboo fiber from tangling due to static electricity during production; Step 5: The blended fibers are roving on a roving machine, then spinning on a spinning machine, and finally twisted and blended again. Existing twisting machines are used for this process. The yarn passes through a slip ring, air ring, over-positioning roller, moving element, pressure roller, and then winding roller, resulting in double twisting. The positioning roller on the pressure roller pulls the yarn, causing it to contact the outer layer of the winding roller. There is yarn between the pressure roller and the winding roller, the purpose of which is to make the twisted yarn compact. With long-term processing, the thickness and weight of the winding roller increase. After the winding roller and the pressure roller come into contact, the pressure on the contact surface between the pressure roller and the yarn increases, resulting in increased yarn tension. Long-term winding will cause yarn wear, which is not conducive to the subsequent use of the yarn. To address this, we propose a double twisting machine for semi-worsted cool-feeling cashmere blended yarn. Summary of the Invention

[0008] Preferably, each of the descending plates is fixedly connected to a first spring at both ends, and the inner ring of the pressure roller is fixedly connected to a fixing plate near both ends of the descending plate, and the fixing plate and the first spring are fixedly connected.

[0009] Preferably, each positioning roller is slidably connected to a lifting ball, a third spring is fixedly installed inside the positioning roller, the third spring and the lifting ball are fixedly connected, and an air pipe is fixedly connected to one side of the positioning roller, with one end of the air pipe passing through the outside of the pressure roller and connected to the negative pressure machine.

[0010] Preferably, a brake cylinder is fixed near the inner ring of the transverse tubes at both ends of the pressure roller. The brake cylinder is divided into two braking areas with the middle of the transverse tubes at both ends as the center. A pair of cylinders are fixedly installed inside the central rotating shaft of each processing area. Each cylinder is placed at an inclined angle inside the central rotating shaft, and one end of each cylinder extends out of the central rotating shaft to form an extension corresponding to the notch of the brake cylinder. A friction block is fixedly installed on each extension.

[0011] Preferably, a drive roller is rotatably mounted on the outside of the base, and multiple sets of pulleys are sleeved on the drive roller. The other end of each set of pulleys is fixed on a central rotating shaft. Each central rotating shaft is provided with a drive gear. A mating gear is fixedly mounted on the end of the pressure roller facing the drive gear. A transmission gear is driven on one side of the processing area of ​​the base.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, after the cashmere yarn is wound several times around the outer ring of the winding roller, the central rotating shaft is driven to rotate. During this rotation, the central rotating shaft drives the pressure roller to rotate, causing the cashmere yarn to slide on multiple rotating positioning rollers. During this process, the cashmere yarn is wound by the winding roller. As the processing time increases, the outer ring of the winding roller becomes thicker, increasing the weight. Simultaneously, as the positioning rollers are compressed, they move radially downwards towards the pressure roller, causing the bottom of the positioning rollers to drive a descending plate to descend. During the descent of the descending plate, the central protrusion drives the transverse tubes at both ends along... When the pressure roller moves axially, the transverse tubes at both ends move axially, causing the slide groove to move vertically with the fixed rod as a limit. This lifts both ends of the winding roller, reducing the pressure on the pressure roller and thus reducing the traction tension of the cashmere yarn. At the same time, when the pressure roller rotates, the pressure roller and the winding roller twist the cashmere yarn. Because the inside of the positioning roller is concave, the cashmere yarn will not detach from the positioning roller during the twisting process. Furthermore, the concavity of the positioning roller corresponds to the outer ring shape of the cashmere yarn, which facilitates the twisting process of the pressure roller and the winding roller, thereby improving the winding efficiency of the processing.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-8This invention provides a technical solution: a semi-worsted cool-feeling cashmere blend yarn twisting machine, comprising a base 1, the base 1 being divided into multiple processing areas, a central rotating shaft 10 rotatably connected to each of the multiple processing areas of the base 1, a limit rod 7 hinged to the top of each of the multiple areas of the base 1, a winding roller 8 suspended at one end of each limit rod 7, and multiple pressure rollers 9 rotatably connected to the outer ring of the central rotating shaft 10, the multiple pressure rollers 9 being respectively placed in each processing area of ​​the base 1, and multiple sliding openings 14 opened on each pressure roller 9, with a positioning roller 20 slidably connected to each sliding opening 14. A descending plate 16 is slidably installed between the pressure roller 9 and the central rotating shaft 10. A pair of transverse tubes 17 at both ends are slidably connected to the pressure roller 9 near the outer ring of the central rotating shaft 10. After the middle part of the descending plate 16 and the pair of transverse tubes 17 at both ends abut against each other, the transverse tubes 17 at both ends move along the axial direction of the pressure roller 9. Fixing rods 28 are fixedly installed on both sides inside the processing area of ​​the base 1. A groove 29 is slidably connected to one end of the fixing rod 28. The bottom of the groove 29 abuts against the other end of the transverse tubes 17 at both ends, and the top abuts against the bottom of the limiting rod 7. The positioning roller 20 is recessed in the middle so that its top forms an arc shape.The positioning roller 20 slides in contact with the cashmere yarn at its recessed area, causing the cashmere yarn to abut against the lifting ball 33. Multiple wicker spools 4 are rotatably connected to the bottom of the base 1. An air ring 5 is fixedly installed at the bottom of the processing area of ​​the base 1. A superposition roller 501 is rotatably connected to the base 1 directly above and next to the air ring 5. A thread drawer 502 is located behind and next to the superposition roller 501 on the base 1. First, the cashmere yarn is placed on the wicker spool 4. The yarn end at the bottom of the wicker spool 4 is pulled out and passed through the slip ring at the top of the wicker spool 4. After passing through the air ring 5 and the yarn guide 502 to straighten the yarn end, it is then passed through the over-positioning roller 501 and placed between the positioning roller 20 and the winding roller 8 for manual traction. Finally, the cashmere yarn is wound around the outer ring of the winding roller 8 several times before the central rotating shaft 10 is driven to rotate. During the rotation of the central rotating shaft 10, the pressure roller 9 is driven to rotate, causing the cashmere yarn to slide on the multiple rotating positioning rollers 20. In this process, the cashmere yarn is wound by the winding roller 8, and with the addition of... As the working time increases, the outer ring of the winding roller 8 becomes thicker, increasing its weight. Simultaneously, as the positioning roller 20 is compressed, it moves radially downwards towards the pressure roller 9. This causes the bottom of the positioning roller 20 to drive the lowering plate 16 to descend. During the descent of the lowering plate 16, the central protrusion drives the two transverse tubes 17 to move axially along the pressure roller 9. When the two transverse tubes 17 move axially, they cause the sliding groove 29 to move vertically, constrained by the fixed rod 28. This lifts both ends of the winding roller 8, reducing the pressure on the pressure roller 9 and thus reducing the traction tension of the cashmere yarn. Simultaneously, as the pressure roller 9 rotates, the pressure roller 9 and the winding roller 8 twist the cashmere yarn. Because the positioning roller 20 has a concave shape, the cashmere yarn will not detach from the positioning roller 20 during twisting. Furthermore, the concavity of the positioning roller 20 corresponds to the outer ring shape of the cashmere yarn, facilitating the twisting process of the pressure roller 9 and the winding roller 8, thereby improving the winding efficiency of the processing.

[0027] Specifically, the base 1 is provided with a pair of transmission rods 3, each of which has a thread 6 at the same position on its exterior. The two transmission rods 3 are slidably connected to multiple movable parts 11. Each movable part 11 is fixedly connected to two sides with connecting pieces 12. Each connecting piece 12 is slidably connected to a movable disk 13 at one end. Each positioning roller 20 slides between two movable disks 13. During the threading process, the thread end is passed through the movable part 11. After the threading is completed, the back drive drives each transmission rod 3 to rotate. During the rotation of the transmission rod 3, the thread 6 is driven to rotate, causing the movable part 11 to move back and forth on the thread 6. This causes the movable disk 13 to move on the pressure roller 9. When the pressure roller 9 rotates, it drives the movable disk 13 to rotate at both ends of the connecting piece 12. At the same time, the positioning roller 20 descends after being stressed. The positioning roller 20 moves radially along the pressure roller 9 on the movable disk 13. During the lateral movement of the movable part 11, the twisting effect of the cashmere yarn is enhanced, improving the quality of the twisting.

[0028] Furthermore, the pressure roller 9 is provided with a slide rail 15 next to the bottom of the positioning roller 20. A second spring 21 is sleeved on the outer ring of the bottom of the positioning roller 20. A ball bearing 23 is fixedly installed on the bottom of the positioning roller 20. The positioning roller 20 is slidably connected to the descending plate 16 through the ball bearing 23. A first spring 19 is fixedly connected to both ends of each descending plate 16. A fixing plate 18 is fixedly connected to both ends of the inner ring of the pressure roller 9 near the descending plate 16. The fixing plate 18 is fixedly connected to the first spring 19. The slide rail 15 can effectively prevent the positioning roller 20 from swinging during the rotation of the pressure roller 9. When the positioning roller 20 is pressed, the first spring 19 is compressed, and the ball bearing 23 and the descending plate 16 roll, reducing friction and increasing the moving speed of the positioning roller 20. When the equipment stops, the cashmere yarn does not need to be processed and can be removed from the equipment. The first spring 19 returns to its original position, and the second spring 21 assists in returning the positioning roller 20 to its original position.

[0029] Furthermore, each positioning roller 20 is slidably connected to a lifting ball 33, and a third spring 34 is fixedly installed inside the positioning roller 20. The third spring 34 and the lifting ball 33 are fixedly connected. An air pipe 22 is fixedly connected to one side of the positioning roller 20. One end of the air pipe 22 passes through the outside of the pressure roller 9 and is connected to the negative pressure machine. When the cashmere yarn comes into contact with the lifting ball 33, the lifting ball 33 descends, the internal channel of the positioning roller 20 opens, and the gas inside the air pipe 22 adsorbs the cashmere yarn onto the positioning roller 20, further preventing the cashmere yarn from detaching from the positioning roller 20.

[0030] Furthermore, a brake cylinder 32 is fixed near the inner ring of the transverse tubes 17 at both ends of the pressure roller 9. The brake cylinder 32 is divided into two braking areas with the middle of the transverse tubes 17 at both ends as the center. A pair of cylinders 31 are fixedly installed inside the central rotating shaft 10 of each processing area. Each cylinder 31 is placed at an inclined angle inside the central rotating shaft 10, and one end of each cylinder 31 extends out of the central rotating shaft 10 to form an extension corresponding to the notch of the brake cylinder 32. A friction block is fixedly installed on each extension. 2 One end can be connected to a fluid detector. When the cashmere yarn breaks, each lifting ball 33 is not subjected to the pressure of the cashmere yarn, and the third spring 34 inside the air pipe 22 bounces up. The lifting ball 33 seals the top of the positioning roller 20. The fluid detector does not detect gas flow and generates an alarm. At the same time, it sends information to the background, causing the cylinder 31 to extend, the friction block and the brake cylinder 32 to contact, and frictional resistance is generated between the pressure roller 9 and the central rotating shaft 10, causing one of the pressure rollers 9 to stop rotating. The equipment can then wait for maintenance personnel to carry out maintenance.

[0031] Specifically, a drive roller 2 is rotatably mounted on the outside of the base 1. Multiple sets of pulleys are fitted onto the drive roller 2, with one end of each pulley fixed to a central rotating shaft 10. Each central rotating shaft 10 is equipped with a drive gear 24. A mating gear 27 is fixedly mounted on the end of the pressure roller 9 facing the drive gear 24. A transmission gear 25 is installed on one side of the processing area of ​​the base 1, meshing with the drive gear 24. A transition gear 26 is coaxially connected to the transmission gear 25, meshing with the mating gear 27. The drive roller 2 rotates, causing the central rotating shaft 10 to rotate. During this rotation, the central rotating shaft 10 drives the drive gear 24, which in turn drives the transmission gear 25. The transmission gear 25 then drives the transition gear 26, causing the mating gear 27 to rotate. The mating gear 27 then drives the pressure roller 9 to rotate. The rotation of the pressure roller 9 causes the positioning roller 20 to rotate and contact the winding roller 8, resulting in the winding roller 8 and the pressure roller 9 rotating in opposite directions.
