[0024] When in use, the servo motor 1 8, the servo motor 2 9 and the drive motor 10 respectively drive the traction roller group 3, the push roller group 4 and the bottom support roller 5 to rotate, and the traction roller group 3 realizes the traction work of the middle film, and the middle film is clamped between the guide roller group 2 and the traction roller group 3. At this time, the middle film can be cut by the slitting mechanism 6, and the cut middle film enters the inside of the push roller group 4. The intermittent work of the push roller group 4 realizes the fixed-length transportation of the middle film, and then the fixed-length cutting mechanism 7 is used to cut the middle film to a fixed length. When the fixed-length cutting mechanism 7 is working, the push roller group 4 stops working. At this time, the cut middle film will temporarily remain between the traction roller group 3 and the push roller group 4 and be in a curved shape. After the fixed-length cutting mechanism 7 completes the cutting, the push roller group 4 and the bottom support roller 5 continue to work to control the cutting cycle, thereby realizing continuous fixed-length cutting;

[0025] Depend on Figures 1 to 4 The slitting mechanism 6 is composed of a slitting motor 11, a main shaft 12, a plurality of slitting disc groups 13 and a plurality of slitting spare disc groups 14.

The main shaft 12 is rotatably connected to the inside of the frame 1 and is fixedly connected to the output shaft of the slitting motor 11. The slitting disc group 13 and the slitting spare disc group 14 are both sleeved on the main shaft 12. The slitting disc group 13 and the slitting spare disc group 14 are both composed of a sliding sleeve 15 and a slitting knife disc 16. The sliding sleeve 1 The sliding sleeve is arranged on the outer surface of the main shaft 12, the slitting blade disc 16 is fixedly connected to the arc-shaped outer surface of the sliding sleeve 15, a plurality of bolt limiting holes 17 are opened on the side of the main shaft 12, and locking bolts 18 matching the bolt limiting holes 17 are arranged on the side of the sliding sleeve 15. A placement bin 19 is fixedly arranged at a position near the slitting mechanism 6 on the back of the frame 1, one end of the main shaft 12 is rotatably connected to the inner side of the placement bin 19, and the slitting spare disc group 14 is located inside the placement bin 19;

[0026] During slitting, the slitting disc set 13 and the slitting spare disc set 14 can be adjusted according to the required cutting width and number. During adjustment, the locking bolt 18 is loosened, and then the sliding sleeve 15 is moved to make the sliding sleeve 15 slide on the main shaft 12. After the adjustment is completed, the locking bolt 18 and the bolt limiting hole 17 are limited and locked. According to the number of cuts, the slitting spare disc set 14 can be taken out from the storage bin 19. During the slitting process, the slitting motor 11 drives the main shaft 12 to rotate, and the main shaft 12 drives the slitting disc set 13 and the slitting spare disc set 14 to rotate, so as to realize the slitting work and improve the smoothness of slitting.
