[0015] Please see Figure 1-4This utility model provides a technical solution: including a device base 1, a device frame 2 fixed on the upper end of the device base 1, a winding shaft 22 rotatably connected to the device frame 2, a winding motor 21 for driving the winding shaft 22 to rotate fixed on the outer side of the device frame 2, a limit plate 23 fixed on the inner side of the winding shaft 22, a positioning sleeve 24 threadedly connected to the outer side of the winding shaft 22, a winding cylinder 3 inserted into the winding shaft 22, side plates 4 fixed at both ends of the winding cylinder 3, a pressure plate 5 slidably connected to the side plate 4 on the side closest to each other, a drive assembly for extending and retracting the pressure plate 5 is provided inside the side plate 4, the winding cylinder 3 is composed of a fixed sleeve 31 and a rotating sleeve 32, the rotating sleeve 32 is rotatably connected to the outer side of the fixed sleeve 31, and an end fixing assembly is provided on the winding cylinder 3.

[0016] The end fixing assembly includes a slot 37 and a positioning plate 34. The slot 37 is opened on the outside of the fixed sleeve 31 and the rotating sleeve 32, and the positions are aligned. The positioning plate 34 is installed on the outside of the fixed sleeve 31. The rotating sleeve 32 has a positioning groove 36 at a position corresponding to the positioning plate 34. The positioning plate 34 is inserted into the positioning groove 36. The fixed sleeve 31 has a telescopic groove 33 at a position corresponding to the positioning plate 34. An ejector spring 35 is fixed between the inner side wall of the telescopic groove 33 and the positioning plate 34.

[0017] The drive assembly includes a sliding groove 51 and a knob 54. The sliding groove 51 is opened in the side plate 4 and is aligned with the pressure plate 5. A threaded rod 53 is rotatably connected in the sliding groove 51. A sliding block 52 is slidably connected in the sliding groove 51 and is fixedly connected to the pressure plate 5. The threaded rod 53 passes through the sliding block 52 and is threadedly connected to the sliding block 52. The knob 54 is rotatably connected to the outside of the side plate 4.

[0018] Working principle: First, connect the entire device to an external power source. Then, insert the winding drum 3 into the take-up shaft 22. Using the limiting plate 23 and the positioning sleeve 24 at both ends, the winding drum 3 can be fixed on the take-up shaft 22. At this time, the rubber end is fixed to the winding drum 3. The take-up motor 21 drives the take-up shaft 22 and the winding drum 3 to rotate, achieving the purpose of winding. During the process, to fix the rubber end, the rubber end can be passed through the slot 37 on the rotating sleeve 32 and inserted into the slot 37 on the fixed sleeve 31. At this time, keep the two slots 37 in the overlapping position. Then, using the rotation of the rotating sleeve 32, the two... Since the slot 37 is misaligned, the rubber end can be fixed by the pressure of the side wall of the slot 37. When the two slots 37 are misaligned, the positioning plate 34 and the positioning groove 36 are aligned. At this time, the positioning plate 34 can be inserted into the positioning groove 36 by the push of the ejector spring 35 to fix the rotating sleeve 32. After winding, the threaded rod 53 can be rotated by the rotation of the knob 54 and the transmission bevel gear 56. This will drive the sliding block 52 and the pressure plate 5 to slide. The pressure plate 5 can squeeze the outside of the rubber roll to achieve the purpose of fixing and prevent the winding cylinder 3 from becoming loose.
