When the cutting knife cuts the film, the lower moving bar will slide up and down inside the support frame. When the cutting knife is away from the film, the device is in a state as follows: Figure 1 In the state shown, the air duct will be aligned with the air supply pipe, so that the air supply pipe delivers high-pressure gas to the inside of the air duct, and the gas is delivered to the inside of the multiple jet pipes through multiple air ducts.

[0018] Furthermore, a heating structure is provided. When the cutting knife cuts the film, the lower moving bar will slide up and down inside the support frame. When the cutting knife is away from the film, the device is in a state as follows: Figure 1 In the state shown, the heating wire and the output wire are connected to each other, so that the power controller supplies power to the heating wire through the output wire, and the connecting electrodes at the bottom of the two heating wires are connected to the cutting knife, so that a path is formed inside the power controller between the output wire, the cutting knife and the heating wire, so that the current flows through the inside of the cutting knife, thereby increasing the temperature of the cutting knife. When the cutting knife cuts the film, the cutting knife has a certain temperature, which prevents the cutting knife from sticking to the film.

[0019] Furthermore, when the cutting knife is attached to the film for cutting, the cutting knife will contact the top of the fixed bar, and the slider will move downward with the cutting knife and the lower moving bar, so that the heating wire and the output wire are separated from each other, and the path formed between the output wire, the cutting knife and the heating wire inside the power controller is disconnected, so that the cutting knife can be heated through the path formed between the output wire, the cutting knife and the heating wire inside the power controller after completing a cutting cycle;

The film transported by the conveyor belt and the support bar will be scooped up by a plurality of wedge blocks, so that the film is completely separated from the support bar, and at the same time, the film passes through a plurality of wedge blocks and enters the top of the fixed bar to wait for processing;

[0021] Furthermore, the upper moving bar is driven by the hydraulic rod to move downward inside the support frame, so that the upper moving bar drives the lower moving bar to move downward through the elastic support rod, so that the cutting knife is driven by the lower moving bar to cut the film. Through the setting of the elastic support rod, the downward pressure output by the hydraulic rod is transmitted secondarily through the elastic support rod. When the cutting knife contacts the material, the cutting knife will drive the lower moving bar and the upper moving bar to compress the elastic support rod, so that the cutting knife and the fixed bar are in flexible contact, thereby preventing the cutting knife from directly contacting the fixed bar rigidly and causing damage to the cutting knife.
