[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment of a film unwinding and rewinding device, including a base plate 1, a first support frame 21, and a dust removal mechanism. The top of the base plate 1 is provided with a dust removal mechanism. The first support frame 21 is fixedly connected to the top of the base plate 1. A slide rod 28 is slidably connected inside the first support frame 21. A connecting frame 27 is fixedly connected to the bottom of the slide rod 28. A correction roller 29 is rotatably connected inside the connecting frame 27. A film body 25 is provided outside the correction roller 29. A slider 2 is slidably connected inside the correction roller 29. 10. A spring 211 is fixedly connected to the inner side of the slider 210, and a correction plate 212 is fixedly connected to the inner side of the spring 211. The correction plate 212 is slidably connected inside the correction roller 29. A first threaded rod 213 is rotatably connected inside the slider 210. The first threaded rod 213 is threadedly connected inside the correction roller 29. The position of the correction plate 212 is positioned by the first threaded rod 213. The base plate 1 can be fixed in a suitable position by bolts. The dust removal mechanism removes dust from the film while simultaneously winding up the film. The connecting frame 27 is limited by the slide rod 28. Adjusting the height of the connecting frame 27 and the straightening roller 29 adjusts the tightness of the film body 25, preventing excessive tension that could cause wrinkles in the film body 25. The slider 210 can be adjusted by rotating the first threaded rod 213. The slider 210 pushes the straightening plate 212 through the spring 211, adjusting the position of the straightening plate 212 so that it is positioned on the film body 25. The first threaded rod 213 can also position the straightening plate 212. The base plate 1 has symmetrical openings inside. Four through holes are provided, and two through slots are symmetrically opened inside the base plate 1. The through slots and through holes facilitate the passage of bolts, so that the position of the base plate 1 can be fixed by bolts and installed in a suitable position for normal operation. The correction roller 29 has matching grooves at the corresponding positions of the slider 210 and the correction plate 212, and the slider 210 and the correction plate 212 slide inside the grooves. The grooves limit the slider 210 and the correction plate 212, so that they can only slide in a straight line inside the grooves, avoiding tilting that could cause jamming or deviation.

[0023] Please see Figure 1 - Figure 3 In this embodiment, an unwinding roller 22 is rotatably connected inside the first support frame 21, and the film body 25 is disposed inside the unwinding roller 22. An electric telescopic rod 26 is fixedly connected to the top of the connecting frame 27 and is fixedly connected inside the first support frame 21. A nut 214 is threaded onto the outside of the first threaded rod 213. A first guide roller 23 is rotatably connected inside the first support frame 21, and a second guide roller 24 is rotatably connected inside the first support frame 21. The height of the correction roller 29 can be adjusted by extending and retracting the electric telescopic rod 26, thereby adjusting the correction roller 29 to a suitable height and adjusting the tightness of the film body 25, thereby ensuring stable transmission of the film body 25.

[0024] Please see Figure 1 , Figure 4 - Figure 5 In this embodiment, the storage mechanism includes a second support frame 31, which is fixedly connected to the top of the base plate 1. A motor 32 is fixedly connected to the front of the second support frame 31, and a take-up roller 33 is fixedly connected to the output end of the motor 32. The take-up roller 33 is rotatably connected inside the second support frame 31. A third guide roller 34 is rotatably connected inside the second support frame 31. An adhesive roller 35 is provided inside the second support frame 31. A positioning plate 36 is slidably connected inside the second support frame 31. A second threaded rod 37 is rotatably connected to the top of the positioning plate 36 and is threaded inside the second support frame 31. The detachable adhesive roller 35 is used to adhere dust to the passing film body 25, removing dust adhering to the surface of the film body 25 and preventing dust from being carried away with the film. The film is rolled up together. The second support frame 31 has a matching groove at the corresponding position of the positioning plate 36, and the positioning plate 36 slides inside the groove. The second support frame 31 has a placement groove at the corresponding position of the adhesive roller 35, and the adhesive roller 35 is placed inside the placement groove. The positioning plate 36 is limited and guided by the groove, so that the positioning plate 36 slides up and down in a straight line. In this way, it can be adjusted up and down with the second threaded rod 37. The film body 25 is respectively placed outside the unwinding roller 22 and the winding roller 33. The film body 25 contacts the correction roller 29, the first guide roller 23, the second guide roller 24, the adhesive roller 35, and the third guide roller 34 in sequence, which guide the film body 25 in sequence and transport the film body 25 smoothly, ensuring the efficiency of unwinding and winding of the film body 25.

[0025] During operation, the base plate 1 is fixed in position, and the film body 25 is pulled off from the outside of the unwinding roller 22, passing sequentially through the alignment roller 29, the first guide roller 23, the second guide roller 24, the adhesive roller 35, the third guide roller 34, and then fixed to the outside of the take-up roller 33. The electric telescopic rod 26 drives the connecting frame 27, which is limited by the sliding rod 28. Adjusting the height of the connecting frame 27 causes the alignment roller 29 to be adjusted to a suitable height, allowing the alignment roller 29 to adjust the tightness of the film body 25. Twisting the first threaded rod 213 pushes the slider 210, which in turn pushes the alignment plate 212 through the spring 211. The alignment plate 212 limits the film body 25 and adjusts it to a suitable position. The first threaded rod 213 is fixed in place, and then the nut 214 is rotated so that the nut 214 abuts against the straightening roller 29, thereby fixing the position of the first threaded rod 213 and preventing the first threaded rod 213 from rotating on its own. The motor 32 drives the take-up roller 33 to rotate, and the take-up roller 33 rotates to wind up the film body 25. The adhesive roller 35 will be driven to rotate by the film body 25. The dust is stuck off by the adhesive roller 35. The second threaded rod 37 is twisted to drive the positioning plate 36 to rise, so that the positioning plate 36 is free from the restraint of the adhesive roller 35. The adhesive roller 35 can then be removed and replaced. The positioning plate 36 only restricts the adhesive roller 35 between the second support frame 31 and the positioning plate 36, but does not clamp the adhesive roller 35. The adhesive roller 35 will rotate as it passes through the film body 25.

[0026] By taking the above steps, the position of the correction plate 212 is adjusted, and the position of the correction plate 212 can be positioned by the first threaded rod 213, so as to solve the problem that when the film is offset, the film will push the semi-ring to move, thus causing the film to always be in an offset state.
