The mounting base 11 has a mounting groove 12 at its front end, and a limiting seat 13 is provided in the mounting groove 12. Limiting posts (not shown in the figure) are provided on both sides of the limiting seat 13, and slots 29 are provided on both sides of the limiting seat 13. The slots 29 serve as limiting positions.

Fixed cylinders 15 are fixedly connected through both sides of the mounting base 11. Telescopic grooves 16 are provided on adjacent sides of the two fixed cylinders 15, and the telescopic grooves 16 communicate with the mounting groove 12 to facilitate the insertion of the insert 18 in the telescopic groove 16 into the mounting groove 12. A pull rod 17 is slidably connected through the telescopic groove 16. The insert 18 is fixedly connected to one end of the pull rod 17, and the pull rod 17 can drive the insert 18 to move. An actuating element 19 is provided on the outside of the fixed cylinder 15. Shearing assemblies are provided on the left side of each of the three moving slots 2. A conveyor frame 26 is provided on the left side of the shearing assemblies. Two conveyor rollers 27 are installed inside the conveyor frame 26. Each conveyor roller 27 consists of a mounting frame and a conveyor roller 27. The mounting frame is used to fix the conveyor roller 27, and the conveyor roller 27 rotates outside the mounting frame. A feeding box 28 is provided on the left side of the conveyor frame 26. The feeding box 28 facilitates the supply of metal wire, and the winding roller 14 generates traction force when it drives the end of the metal wire to rotate.

[0034] Reference Figure 5 The shearing assembly includes a shearing frame 23, which is located outside the moving groove 2 and its bottom is fixedly connected to the base 1. Cylinders 24 are fixedly connected to both inner sides of the shearing frame 23. A controller mounted on the front end of the base 1 can simultaneously control the synchronous movement of the two cylinders 24. A cutter 25 is fixedly connected to the output end of each cylinder 24. The cylinders 24 of the shearing assembly can drive the cutter 25 to move, thus shearing the wound metal wire.

[0035] Reference Figure 1-5Three first motors 4 are fixedly connected to the rear end of the base 1, and the output end of the first motor 4 is fixedly connected to the threaded rod 3, which can drive the threaded rod 3 to rotate. The rear end of the rotating rod 9 is fixedly connected to the second gear 10, which meshes with the first gear 8 to play a transmission role, facilitating the rotation of the second gear 10 through the first gear 8. Two limiting grooves 22 are opened in the mounting groove 12, and the limiting seat 13 is set in the limiting groove 22. Limiting posts are installed on both sides of the limiting seat 13, and the limiting seat 13 can be inserted into the limiting groove 22 through the limiting posts on both sides. The insertion post 18 is set in the telescopic groove 16, and the outside of the insertion post 18 is slidably connected to the inner wall of the telescopic groove 16, which facilitates the extension and retraction of the insertion post 18 within the telescopic groove 16. A rotating shaft 20 is rotatably connected through the middle of the lever 19, and the outer ring of the rotating shaft 20 is rotatably connected to the outward end of the pull rod 17. The lever 19 and the pull rod 17 are connected through the rotating shaft 20. A spring 21 is fitted around the outer ring of the pull rod 17, and the spring 21 is located in the telescopic groove 16. The spring 21 can be reset to drive the insertion post 18 to extend out of the telescopic groove 16 and insert into the slot 29.

[0036] Working principle: In use, one end of the metal wire is inserted into the limiting slot (not shown in the figure) at the end of the winding roller 14. Then, the second motor 7 is started, and its output end drives the first gear 8 to rotate. The first gear 8 meshes with the second gear 10 at the rear end of the rotating rod 9, thereby transmitting power to the rotating rod 9. This causes the rotating rod 9 to drive the mounting seat 11 at the front end to rotate, providing the power basis for the winding action of the winding roller 14. At the same time, the first motor 4 is started, driving the threaded rod 3 to rotate. The threaded rod 3 drives the moving seat 5 to move forward at a constant speed. At this time, the metal wire is wound on the outside of the winding roller 14, forming a spring-like helical structure. After winding, the two cylinders 24 in the shearing frame 23 are started, driving the cutter 25 to move relative to each other, cutting the metal wire and completing the winding process. Furthermore, by simultaneously starting multiple first motors 4 and second motors 7 through the simultaneous controller, it is ensured that the power transmission mechanism of the winding roller 14 on the three moving seats 5 is the same. Therefore, multiple wires can be wound synchronously on the winding roller 14 to form a spring-like helical structure. When the winding roller 14 needs to be replaced, the levers 19 on both sides of the mounting base 11 are moved so that the levers 19 rotate 90° and the bottom of the levers 19 is perpendicular to the outside of the fixed cylinder 15 for limiting. At this time, the levers 19 rotate around the pivot 20, which can pull the pull rod 17. The pull rod 17 drives the insert 18 to compress the spring 21 and retract it into the telescopic groove 16. At this time, the insert 18 disengages from the slots 29 on both sides of the limiting seat 13, and the limiting seat 13 can be pulled out from the mounting groove 12 and the limiting groove 22 to replace the winding roller 14. During installation, the limiting seat 13 is inserted into the mounting groove 12 and the limiting groove 22, and the levers 19 are moved back. At this time, the spring 21 returns to its original position and drives the insert 18 to extend out of the telescopic groove 16 and insert into the slots 29 on both sides of the limiting seat 13 to complete the installation of the winding roller 14.
