This reduces production time and improves production efficiency.
[0034] Furthermore, the fixing component 42 includes a fourth support frame 421, which is fixedly connected to the top of the support platform 1.

[0035] Furthermore, there are two sets of mounting plates 415, distributed around the rotating rod 417.

There are five sets of support plates 4112, distributed circumferentially around the rotating rod 417. The support plate 4112 is slidably connected to the gear plate 418, allowing for quick replacement of the sleeve.
[0036] Furthermore, there are two sets of connecting rod housings 425, symmetrically distributed around the third roller 426. The moving rod 423 is slidably connected to the connecting rod housing 425, effectively controlling the fixation of the membrane.
[0037] In actual operation, when this device is used, first rotate the threaded sleeve 416, lift the rotating rod 417, and put the required sleeve on the outside of the support plate 4112. Then, tighten the threaded sleeve 416 so that both ends are threadedly connected to the mounting plate 415 and the rotating rod 417 respectively, and fix the rotating rod 417. Turn on the second motor 4113 to make the gear 4114 rotate, which drives the gear disk 418 to rotate at the same time, so that the support plate 4112 slides in the first slide groove 419 and the second slide groove 4111 to fix the sleeve. Then, the film to be wound is passed through the first drive shaft 23, and then passes over the second roller 38 and under the third roller 426 until it is attached to the outside of the support plate 4112. At this time, press the moving rod 423 to cause the spring 424 to contract, and at the same time rotate the connecting rod housing 425. The connecting rod housing 425 rotates to a certain angle, causing the third roller 426 to rest on the outside of the support plate 4112, compressing and fixing the film. At this time, the moving rod 423 is released, causing the spring 424 to rebound, allowing the moving rod 423 to be locked in the slot 422, fixing the connecting rod housing 425. When the film is fixed, the servo first motor 33 is turned on, causing the first helical gear 34 to rotate, driving the second helical gear 36, which is meshed with it, to rotate simultaneously. At this time, the connecting plate 37, which is threaded to it, moves upward, causing the second roller 38 to press against the film, increasing the film tension. At this time, the first motor 22 is turned on, causing the first drive shaft 23 to rotate, driving the second drive shaft 414 to rotate via the belt 25. At this time, the mounting plate 415 drives the rotating rod 417 to rotate via the bearing 413, winding the film.
