Description
Technical Field
[0001] The utility model relates to the technical field of spinning, in particular to a twisting device for spinning high-strength nylon fibers. Background Art
[0002] High-strength nylon fiber is a synthetic fiber made from nylon 6 or nylon 66 resin through polymerization, spinning, stretching and other processes. It has high strength, good wear resistance, good elasticity and light weight, and is widely used in tires, cables, ropes, clothing and other fields. However, when producing high-strength nylon fiber, a twisting device is required. This is because the twisting device can twist the spun fiber, causing the fiber to twist to a certain extent, thereby increasing the strength and wear resistance of the fiber, improving the wind resistance and stability of the fiber, and making it more suitable for occasions that require high strength and wear resistance.
[0003] In the traditional high-strength nylon fiber spinning process, the use of the twisting device is a key link. The device twists the initially formed nylon fiber to give the fiber a certain twist, thereby significantly improving its strength and wear resistance. In specific operation, after the fiber is stretched to a certain strength during the spinning process, it enters the twisting device, and the rotating spindle applies torque to the fiber, so that it is twisted under certain density and uniformity requirements, and finally wrapped around the outer wall of the line roller for centralized finishing.
[0004] When the above-mentioned twisting device is in use, the twisted spun yarn needs to be wound around the outer wall of the wire roller. At this time, the wire roller needs to rotate at a specified position to facilitate spinning winding. This arrangement also makes it difficult to disassemble and assemble the wire roller and the spun yarn wrapped around the outer wall after spinning winding, thereby limiting the flexibility of the production line and significantly reducing production efficiency.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 - Figure 4 , the utility model provides an embodiment: a twisting device for high-strength nylon fiber spinning, including a fixed support 1, the fixed support 1 is internally rotatably connected with a toothed cam wheel 2, the toothed cam wheel 2 is internally fixedly connected with a rotating shaft 3, the rotating shaft 3 is internally slidably connected with a push rod 4, the internal slidably connected with a limiting block 5, the outer wall of the limiting block 5 is slidably connected with a wire roller 13, the wire roller 13 is internally slidably connected with a push plate 6, the outer wall of the push plate 6 is fixedly connected to the outer wall of the limiting block 5, the outer wall of the push plate 6 is fixedly connected with a slide bar 8, the outer wall of the slide bar 8 is slidably connected to the inside of the wire roller 13, the outer wall of the slide bar 8 is sleeved with a spring 7, one end of the spring 7 is fixedly connected to the outer wall of the push plate 6, the other end of the outer wall of the spring 7 is fixedly connected to the inside of the wire roller 13, the inside of the slide bar 8 is fixedly connected with a rack 9, the inside of the wire roller 13 is internally rotatably connected with a gear 10, the rack 9 is meshed with the gear 10, and a support assembly is provided on the upper surface of the fixed support 1;
[0026] Specifically, first, push rod 4 is pushed to slide inside fixed support 1, driving one end of push rod 4 to contact with limit block 5, and pushing limit block 5 to slide inside rotating shaft 3 and line roller 13. With the movement of limit block 5, push plate 6 and slide bar 8 will also slide inside line roller 13 together. In this process, push plate 6 will apply pressure to spring 7 to contract spring 7, and then the movement of slide bar 8 will further drive the rack 9 connected thereto to move. Since there is a meshing relationship between rack 9 and gear 10, the movement of rack 9 will cause gear 10 to rotate accordingly, and the rotation of gear 10 will further drive the slide bar 8 on the other side to slide, thereby realizing the synchronous movement of limit blocks 5 on both sides out of the rotating shaft 3. When limit block 5 is completely moved out of rotating shaft 3, line roller 13 and the wiring harness thereon can be easily removed, which not only realizes the convenient installation and disassembly of line roller 13 and high-strength nylon fiber spinning, but also greatly improves the stability and reliability of the equipment.
[0027] Reference Figure 1 The support assembly includes a bracket 11, the lower surface of the bracket 11 is fixedly connected to the upper surface of the fixed support 1, and the inner part of the bracket 11 is rotatably connected to a roller 12
[0028] Specifically, during the installation process, it is only necessary to place the wire roller 13 on the inner wall of the bracket 11 in the support assembly and gently rotate the wire roller 13. When the wire roller 13 rotates to a certain angle, the spring 7 will use its own accumulated elastic potential energy to accurately send the limit block 5 into the interior of the rotating shaft 3, thereby achieving a stable connection between the wire roller 13 and the rotating shaft 3.
[0029] Reference Figure 1 , Figure 2 and Figure 5 The outer wall of the fixed support 1 is fixedly connected with a motor 14, the output end of the motor 14 is fixedly connected with a toothed cam wheel 2 15, a toothed transmission belt 16 is arranged inside the fixed support 1, the toothed transmission belt 16 is meshed with the toothed cam wheel 2 15, the toothed transmission belt 16 is meshed with the toothed cam wheel 1 2, the inside of the toothed cam wheel 2 15 is fixedly connected with a bidirectional screw 17, both ends of the bidirectional screw 17 are rotatably connected to the inside of the fixed support 1, the upper surface of the fixed support 1 is fixedly connected with a guide rail 18, the outer wall of the bidirectional screw 17 is threadedly connected with a fixed block 20, the lower surface of the fixed block 20 is fixedly connected with a slider 19, the outer wall of the slider 19 is slidably connected to the outer wall of the guide rail 18, the inside of the fixed block 20 is fixedly connected with a rotating shaft 21, the outer wall of the rotating shaft 21 is rotatably connected with an auxiliary cam wheel 22, and the outer wall of the auxiliary cam wheel 22 is rotatably connected to the inside of the fixed block 20;
[0030] Specifically, the high-strength nylon fiber is first spun through the fixed block 20 to firmly fix it on the outer wall of the line roller 13, and then the output end of the motor 14 drives the toothed cam wheel 2 15 to rotate, and then the toothed cam wheel 1 2 is transmitted to the toothed cam wheel 1 2 through the toothed transmission belt 16 to ensure that the toothed cam wheel 1 2 and the toothed cam wheel 2 15 keep rotating synchronously. With the synchronous rotation of the toothed cam wheel 1 2 and the toothed cam wheel 2 15, the line roller 13 and the bidirectional screw 17 will also rotate synchronously. In this process, the main function of the line roller 13 is to sort and wind the wire bundle. At the same time, the rotation of the bidirectional screw 17 will drive the fixed block 20 to reciprocate on its outer wall. It not only helps to evenly wind the high-strength nylon fiber spinning around the line roller 13, ensuring that the high-strength nylon fiber spinning can be orderly attached to the outer wall of the line roller 13, the guide rail 18 provides a clear path for the movement of the fixed block 20, and the slider 19 ensures the stability of the fixed block 20 during the movement. Finally, the high-strength nylon fiber spinning will pass through the outer wall of the auxiliary concave wheel 22 during the transportation process. Due to the friction between the spinning and the auxiliary concave wheel 22, the auxiliary concave wheel 22 will naturally rotate on the outer wall of the rotating shaft 21, which not only reduces the friction loss of the high-strength nylon fiber spinning during the transportation process, but also improves the efficiency of the entire winding process.
[0031] Working principle: When the high-strength nylon fiber spinning twisting device is needed, first push the push rod 4 to slide inside the fixed support 1, thereby driving one end of the push rod 4 to push the limit block 5 to slide inside the rotating shaft 3 and the line roller 13. When the limit block 5 moves, it will drive the push plate 6 and the slide bar 8 to slide inside the line roller 13. In this process, the push plate 6 applies pressure to the spring 7 to shrink the spring 7, and then the movement of the slide bar 8 drives the rack 9 to move. Due to the meshing relationship between the rack 9 and the gear 10, The gear 10 rotates with the rotation of the rack 9, thereby driving the slide bar 8 on the other side to slide, and then the limit blocks 5 on both sides are synchronously moved out of the interior of the rotating shaft 3, and then the line roller 13 and the wire harness can be removed. When installing, the line roller 13 needs to be placed on the inner wall of the bracket 11, and then the line roller 13 is rotated. When the line roller 13 rotates to a certain angle, the limit block 5 can be accurately pushed to the interior of the rotating shaft 3 through the spring 7 for connection, so as to achieve the effect of facilitating the installation and removal of the line roller 13 and the high-strength nylon fiber spinning;
[0032] In addition, the high-strength nylon fiber is first spun through the fixed block 20 and fixed on the outer wall of the online roller 13, and then the toothed cam wheel 2 15 is driven to rotate through the output end of the motor 14, and then the toothed cam wheel 1 2 is driven to rotate through the toothed transmission belt 16, so that the toothed cam wheel 1 2 and the toothed cam wheel 2 15 rotate synchronously, and then the line roller 13 and the bidirectional screw 17 rotate synchronously. In this process, the wire bundle is arranged and wound by the line roller 13, and then the fixed block 20 is reciprocated on the outer wall of the bidirectional screw 17 through the rotation of the bidirectional screw 17, and then the movement of the fixed block 20 is limited and guided by the guide rail 18 and the slider 19, so that the high-strength nylon fiber is evenly wound on the outer wall of the online roller 13. The high-strength nylon fiber will slide on the outer wall of the auxiliary cam wheel 22 during the transportation process, and at this time, the auxiliary cam wheel 22 will be driven to rotate on the outer wall of the rotating shaft 21, thereby reducing the friction of the high-strength nylon fiber spinning.
