The fixed knife is arranged on the guide support shaft 8 and is matched with the movable knife rest 5 which axially moves along the guide support shaft 8, so that films with different widths are cut.

The limiting support 6 is arranged on the equipment support and located below the guide support shaft 8, and limiting switches 7 are arranged at two ends of the limiting support 6 and used for limiting the position of the movable tool rest 5.

During operation, the motor 1 drives the speed reducer 2 to drive the screw rod 3, and the screw rod 3 drives the nut key 11, so that the nut key 11 drives the movable tool rest 5 to axially move along the guide support shaft 8. The moving blade holder 5 moves the blade 9 through the cylinder assembly 10. In the figure 1, a limit switch 7 is arranged on a limit bracket 6 at the position 1 and the position 2 to protect a blade 9 from exceeding an adjustment range; the blade 9 can move in the range between the position 1 and the position 2, can lift and fall under the action of the air cylinder assembly 10, and can be matched with the fixed knife for use, so that films with different widths can be cut.

The utility model has the beneficial effects that: according to the utility model, the screw rod is arranged in the guide support shaft, so that the contact of rubber materials and the screw rod is avoided, the clamping stagnation of a rubber sheet caused by the movement of the cutter is prevented, and the pollution of the rubber materials caused by the contact of the rubber materials with screw rod lubricating oil is avoided; meanwhile, the screw rod is arranged inside the guide support shaft, so that the screw rod is protected necessarily, the installation space is reduced, and the structure is compact and attractive.
