[0033] Please see Figure 1-4 This utility model provides a technical solution: a high-speed winding structure for ultrafine wire based on a spring winding device, including a spring winding device base 1, a connecting seat 2 fixedly installed on the right side of the upper surface of the spring winding device base 1, and a tension adjustment box 3 installed on the connecting seat 2;

[0034] Among them, a support side plate 4 is fixedly installed on the upper surface of the spring winding equipment base 1 corresponding to the right side of the connecting seat 2.

A thread feeding mechanism is provided on the outer surface of the first thread hanging rod 5 and the second thread hanging rod 7. This mechanism is used to perform thread feeding operation on the filament.

[0035] Among them, a wire feeding protective cover 8 is installed on the front surface of the support side plate 4 at the position below the second wire hanging rod 7.

[0036] Furthermore, a tension feed wheel 9 is rotatably mounted on the lower side of the front surface of the tension regulating box 3, a tension rod 10 is mounted on the upper side of the front surface of the tension regulating box 3, a tension spring 11 is mounted on the tension rod 10, and the end of the tension spring 11 away from the tension rod 10 is fixedly mounted on the front surface of the tension regulating box 3.

[0037] Furthermore, the wire feeding mechanism includes two wire feeding shaft fixing discs 12. The two wire feeding shaft fixing discs 12 are respectively sleeved and rotatably installed on the outer surface of the first wire hanging rod 5 and the second wire hanging rod 7 at one end near the support side plate 4. A rotating shaft 13 is fixedly installed at the center of the front end of each wire feeding shaft fixing disc 12. The two rotating shafts 13 are rotatably connected to the first wire hanging rod 5 and the second wire hanging rod 7 respectively.

[0038] Furthermore, a wire-winding tube 14 is slidably mounted on the outer surface of the rotating shaft 13;

[0039] Among them, limit plates 15 are fixedly installed on both the upper and lower sides of the outer surface of the rotating shaft 13, and limit grooves 16 are opened in the inner part of the winding tube 14 corresponding to the positions of the two limit plates 15. The limit plates 15 and the limit grooves 16 are slidably connected.

[0040] Furthermore, a movable disk 17 is provided on the front side of the rotating shaft 13;

[0041] Among them, the front surface of the rotating shaft 13 is fixedly installed with snap-fit ​​blocks 18 on both the upper and lower sides, and snap-fit ​​holes 19 are opened on the snap-fit ​​blocks 18.

[0042] The rear surface of the movable disk 17 is provided with a snap-fit ​​groove 20 at the position corresponding to the two snap-fit ​​blocks 18, and a circular groove 21 is provided inside the snap-fit ​​groove 20 at the position corresponding to the snap-fit ​​hole 19.

[0043] Furthermore, a spring 22 is fixedly installed at the bottom of the inner side of the circular groove 21, and a snap-fit ​​rod 23 is fixedly installed at the end of the spring 22 away from the circular groove 21. The snap-fit ​​rod 23 is slidably connected to the inside of the circular groove 21, and the end of the snap-fit ​​rod 23 away from the spring 22 is set with an inclined surface.

[0044] Furthermore, rectangular holes 24 are provided on the front surface of the movable disk 17 at the positions corresponding to the locking rod 23. An operating rod 25 is slidably installed inside the rectangular hole 24. The operating rod 25 is fixedly connected to the outer surface of the locking rod 23. When using this device, a high-speed servo motor is used to support high-speed winding of ultra-fine wires. The high speed and high precision greatly improve production efficiency. The motor is used in conjunction with the wire hanging rod to achieve the function of active wire release, avoiding the wire breakage caused by passive wire pulling. A wire release protection function is also added to protect the wire from being pulled apart when the winding and releasing speeds are mismatched.

[0045] This significantly improves the utilization rate of the wire material, reduces costs, and decreases the time wasted on frequent wire changes, thus increasing efficiency. Combined with tension bars and springs of different specifications, it achieves precise control of the winding tension, ensuring the stability and consistency of the filaments during winding. It also improves the product qualification rate. By setting up a combined winding shaft, when installing the winding shaft, the limiting groove 16 on the winding tube 14 is aligned with the limiting plate 15 on the outer surface of the rotating shaft 13, and then it is fitted onto the outer surface of the rotating shaft 13, thus limiting the winding tube 14 to the outer surface of the rotating shaft 13. Then, the snap-fit ​​groove 20 on the moving disk 17 is aligned with the snap-fit ​​block 18, and the snap-fit ​​block 18 is inserted into the corresponding snap-fit ​​groove 20. This causes the snap-fit ​​block 18 to push the corresponding snap-fit ​​rod 23 into the circular groove 21, causing the spring 22 to contract. When the snap-fit ​​rod on the snap-fit ​​block 18... When the hole 19 moves below the locking rod 23, the spring 22 extends and springs the locking rod 23 into the locking hole 19, thereby locking the moving disk 17. The moving disk 17 limits the winding tube 14 to the outer surface of the rotating shaft 13. When it is necessary to disassemble and replace the worn winding tube 14, pull the two operating rods 25 to drive the locking rod 23 out of the locking hole 19, and the moving disk 17 can be moved away, so that the winding tube 14 slides away from the outer surface of the rotating shaft 13 for replacement. The operation is simple and the winding shaft can be replaced quickly, which improves the practicality of the device.

[0046] Working Principle: This device utilizes a high-speed servo motor to support high-speed winding of ultra-fine filaments. The high speed and precision significantly improve production efficiency. The motor, combined with a wire-feeding rod, enables active wire release, preventing wire breakage due to passive pulling. A wire-feeding protection function is also added to prevent wire breakage in cases of mismatch between winding and releasing speeds. This greatly improves wire utilization, reduces costs, and minimizes time wasted on frequent wire changes, further enhancing efficiency. The use of tension rods and springs of different specifications allows for precise control of winding tension, ensuring the stability and consistency of the filaments during winding. To improve product qualification rate, a combined winding shaft is used. During installation, the limiting groove 16 on the winding tube 14 is aligned with the limiting plate 15 on the outer surface of the rotating shaft 13, and then fitted onto the outer surface of the rotating shaft 13. This limits the winding tube 14 to the outer surface of the rotating shaft 13. Then, the snap-fit ​​groove 20 on the moving disk 17 is aligned with the snap-fit ​​block 18, and the snap-fit ​​block 18 is inserted into the corresponding snap-fit ​​groove 20. This causes the snap-fit ​​block 18 to push the corresponding snap-fit ​​rod 23 into the circular groove 21, causing the spring 22 to contract. When the snap-fit ​​rod 23 on the snap-fit ​​block 18... When the hole 19 moves below the locking rod 23, the spring 22 extends and springs the locking rod 23 into the locking hole 19, thereby locking the moving disk 17. The moving disk 17 limits the winding tube 14 to the outer surface of the rotating shaft 13. When it is necessary to disassemble and replace the worn winding tube 14, pull the two operating rods 25 to drive the locking rod 23 out of the locking hole 19, and the moving disk 17 can be moved away, so that the winding tube 14 slides away from the outer surface of the rotating shaft 13 for replacement. The operation is simple and the winding shaft can be replaced quickly, which improves the practicality of the device.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
