[0022] Among them, the film positioning frame 4 includes a limit frame 41, which is fixedly installed at one end of the conveying support structure 1. A sliding groove 42 is opened inside the limit frame 41, and an axle-rotating screw 44 is rotatably installed inside the sliding groove 42. A rotating wheel 43 is fixedly installed on the side of the axle-rotating screw 44, and the rotating wheel 43 is rotatably installed on the side of the limit frame 41.

[0023] Among them, the film positioning assembly 5 includes a sliding block 51, which is threadedly installed on the outer surface of the sliding groove 42, and a support block 52 is fixedly installed on the bottom of the sliding block 51. The sliding block 51 is slidably installed inside the sliding groove 42, and a moving roller 53 is rotatably installed on the side of the support block 52. A support rod 54 is fixedly installed on the side of the lower end of the support block 52, and a support roller 55 is movably sleeved on the outer surface of the support rod 54. The moving rollers 53 are arranged to make the moving rollers 53 close to each other. When limiting the film, the film is assisted to move by rolling the moving rollers 53. Similarly, the support rollers 55 support the film while rolling during the auxiliary movement of the film, thereby avoiding wear of the film during the sliding process and improving the quality of the film.

[0024] Among them, the film cutting assembly 6 includes a metal base plate 61, a cutting groove 62 is opened inside the metal base plate 61, a cutting frame 63 is fixedly installed on the top of the metal base plate 61, and a connecting rod 65 is movably sleeved inside the cutting frame 63. An electromagnet block 64 is fixedly installed on the bottom of the connecting rod 65, and a groove corresponding to the cutting groove 62 is opened inside the electromagnet block 64.
