[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The tension - balanced aluminum enameled wire pay - off stand is a device used to maintain the balanced tension of the enameled wire during the winding process, and it is crucial for ensuring the quality and efficiency of coil winding.

[0026] Please refer to Figures 1-5 As shown in the figure, this embodiment provides a tension - balanced aluminum enameled wire pay - off stand, including a workbench 1. In order to prevent the wound coil 11 from loosening when the winding of the coil 11 ends, specifically as follows: There is a side plate 28 on the top of the workbench 1. A slide bar 27 is slidably connected inside the side plate 28. The outer surface of the slide bar 27 is provided with a coil 11. A connecting plate 231 is fixedly connected to the outer surface of the upper end of the side plate 28. A cylinder 23 is fixedly connected to the bottom of the connecting plate 231. A lower pressing plate 2 is fixedly connected to the bottom of the cylinder 23. A fixed plate 21 is fixedly connected to the front of the lower pressing plate 2. A support plate 223 is fixedly connected to the outer surface of the lower end of the side plate 28. The end of a telescopic rod 222 is fixedly connected to the top of the support plate 223. A spring 221 is sleeved outside the telescopic rod 222. The end of the spring 221 is fixedly connected to the top of the support plate 223. The other ends of the spring 221 and the telescopic rod 222 are fixedly connected to an extrusion plate 22. The lower pressing plate 2 moves along its length direction on the cylinder 23. However, in the existing tension - balanced aluminum enameled wire pay - off stand, during the use process, when the winding on the winding coil is almost finished, the wire will fall off from the winding coil, resulting in the loosening of the wire on the wound coil 11, thus causing the winding to be uneven.

[0027] The improvement of this embodiment lies in:

[0028] First, the first motor 26 rotates to drive the slide bar 27 to rotate. Then, the rotation of the slide bar 27 drives the coil 11 to rotate and unwind the wire. Immediately afterwards, the cylinder 23 expands and contracts to drive the lower pressing plate 2 to move up and down. When the lower pressing plate 2 moves up and down and clamps the wire on the pressing plate 22, the spring 221 expands and contracts to protect the wire from being easily crushed. And when there is no wire on the coil 11, the wire is clamped by the lower pressing plate 2 and the pressing plate 22, so that the wire on the wound coil 11 will not become loose.

[0029] In order to facilitate the rotation of the slide bar 27, therefore, the end of the slide bar 27 is fixedly connected to the end of the first motor 26, and the other end of the first motor 26 is fixedly connected to the support plate 25. First, the rotation of the first motor 26 drives the slide bar 27 to rotate, and then the convenience of the rotation of the slide bar 27 is realized.

[0030] In order for the coil 11 to rotate and unwind the wire, therefore, a plug 241 is inserted into the other end of the slide bar 27. The outer surface of the plug 241 is fixedly connected to a circular plate 24. The outer surface of the circular plate 24 is threadedly connected to a bolt 242. The end of the bolt 242 is threadedly connected inside the coil 11. First, the rotation of the slide bar 27 drives the plug 241 to rotate. Then, the rotation of the plug 241 drives the circular plate 24 to rotate. Immediately afterwards, the rotation of the circular plate 24 drives the bolt 242 to rotate. At the same time, the rotation of the bolt 242 drives the coil 11 to rotate, realizing that the coil 11 can rotate and unwind the wire.

[0031] Secondly, in order for the slide bar 27 to be applicable to coils 11 of different lengths, therefore, a bidirectional telescopic plate 3 is fixedly connected to the inner surface of the side plate 28. The bottom of the bidirectional telescopic plate 3 is fixedly connected to the top of the workbench 1. The top of the bidirectional telescopic plate 3 is fixedly connected to the bottom of the support plate 25. The front end of the bidirectional telescopic plate 3 is rotatably connected to the end of a threaded rod 31. The other end of the threaded rod 31 is fixedly connected to the end of the second motor 35. A moving block 34 is threadedly connected to the outer surface of the threaded rod 31. The outer surfaces on both sides of the moving block 34 are rotatably connected to a rotating plate 33. The back of the rotating plate 33 is rotatably connected to the front of the side plate 28. First, the second motor 35 rotates to drive the threaded rod 31 to rotate. Then, the rotation of the threaded rod 31 drives the moving block 34 to move back and forth. Immediately afterwards, the back-and-forth movement of the moving block 34 drives the angle of the rotating plate 33 to become larger and smaller. And the change in the angle of the rotating plate 33 drives the side plate 28 to move in and out. At the same time, the in-and-out movement of the side plate 28 drives the bidirectional telescopic plate 3 to expand and contract, realizing that the slide bar 27 can be applicable to coils 11 of different lengths.

[0032] Considering that the moving block 34 is prone to rotation, therefore, the end of the cylindrical rod 32 is fixedly connected to the front of the two-way telescopic plate 3. The other end of the cylindrical rod 32 is fixedly connected to the mounting plate 36. The back of the mounting plate 36 is fixedly connected to the other end of the second motor 35. The bottom of the mounting plate 36 is fixedly connected to the top of the workbench 1. The outer surface of the cylindrical rod 32 is slidably connected inside the moving block 34. First, the workbench 1 fixes the two-way telescopic plate 3 and the mounting plate 36. Then, the two-way telescopic plate 3 and the mounting plate 36 fix the cylindrical rod 32. Immediately afterwards, the cylindrical rod 32 fixes the moving block 34, realizing that the moving block 34 does not rotate.

[0033] To sum up, the working principle of this solution is as follows:

[0034] Manually unscrew the bolt 242, hold the circular plate 24 and pull it outwards, pull out the plug 241 from the slot opened at the end of the sliding rod 27, remove the coil 11. After replacing it with a new coil 11, hold the circular plate 24 and push it inwards, insert the plug 241 into the slot opened at the end of the sliding rod 27, hold the bolt 242 and tighten it. Connect the second motor 35 to the power supply. Drive the threaded rod 31 to rotate through the rotation of the second motor 35. Drive the moving block 34 to move backward through the rotation of the threaded rod 31. Immediately afterwards, the backward movement of the moving block 34 drives the rotating plate 33 to increase the angle, and the increase in the angle of the rotating plate 33 drives the side plate 28 to move outwards. At the same time, the outward movement of the side plate 28 drives the two-way telescopic plate 3 to extend, making the outer surface of the side plate 28 closely adhere to the end of the coil 11, making the wire on the coil 11 easier to pass through the holes on the fixing plate 21, reducing the surface damage caused by the wire scraping on the wall of the fixing plate 21 due to excessive inclination, and the wire can be released on both sides, with higher efficiency. Pass the wire on the coil 11 through the holes on the fixing plate 21 and press it between the lower pressing plate 2 and the pressing plate 22. The wire can pass between the lower pressing plate 2 and the pressing plate 22 through the fixing plate 21. Connect the first motor 26 to the power supply. Drive the sliding rod 27 to rotate through the rotation of the first motor 26. Drive the coil 11 to rotate and release the wire through the rotation of the sliding rod 27. Drive the lower pressing plate 2 to move up and down through the telescopic movement of the cylinder 23. When the wire is clamped on the pressing plate 22 through the up and down movement of the lower pressing plate 2, the shortening degree of the spring 221 is determined by the extended length of the cylinder 23. When the spring 221 shortens, the elastic force of the spring 221 rebounds to drive the pressing plate 22 to press upwards to determine the tension size. When the wire on the coil 11 is released, clamp the wire through the lower pressing plate 2 and the pressing plate 22 to prevent the wire head from falling off and causing the wire on the wound coil 11 to become loose, resulting in a decline in product quality.
