[0023] A fixed plate 10 is connected to the workbench 1, and a movable plate 11 is connected to one end of the first slide groove 3 by bolts. A first motor 12 is installed on the first mounting plate 5, and the output shaft of the first motor 12 is connected to the first threaded rod 13. The smooth rod 8 is arranged below the first threaded rod 13, and the first threaded rod 13 is rotatably connected in the second slide groove 4. The connecting block 16 is slidably connected to the smooth rod 8. When the movable block 14 moves, the connecting block 16 connected below the movable block 14 will slide on the smooth rod 8, thereby guiding the movement of the movable block 14 and preventing the movable block 14 from rotating with the first threaded rod 13.
[0024] A moving block 14 is threadedly connected to the first threaded rod 13, a cutting blade 15 is connected above the moving block 14, a connecting block 16 is connected below the moving plate 11, a second mounting plate 17 is connected to one side of the fixed plate 10, a second motor 18 is installed on the second mounting plate 17, a rotating rod 19 is connected to the output shaft of the second motor 18, a slider 20 is connected below the moving plate 11, second threaded holes 27 are provided on both sides of the slider 20 and both sides of the first slide groove 3, the slider 20 slides in the first slide groove 3, two support tubes 7 are respectively arranged on both sides of the support frame 9, and the protective film is supported by the downward pressure of the flattening roller 33 and the support of the support tube 7 to the protective film to prevent the protective film from fluttering and ensure the flatness of the protective film.
