[0028] Working principle:

[0029] When the cutting device for processing polyimide film is used, the electric telescopic rod 3 drives the connecting frame 4 to move, and the distance between the two protective shells 9 is adjusted according to the width of the polyimide film. The connecting plate 6 is pulled upward by the handle 7, and the connecting plate 6 drives the protective shell 9 to move upward through the connecting column 5, so that the clamping wheel 11 is separated from the workbench 1, and at the same time, the protective shell 9 compresses the supporting spring 8, and the polyimide film passes from under the clamping wheel 11 and is wound around the outside of the winding roller 20. The handle 7 is released, and the supporting spring 8 supports the protective shell 9, so that the clamping wheel 11 is pressed on the surface of the polyimide film. Under the premise of ensuring the smooth movement of the polyimide film, the polyimide film is pressed;

[0030] Start the drive motor 21 to drive the winding roller 20 to rotate and pull the polyimide film. According to actual use requirements, the polyimide film is rolled up to a suitable length, and the drive motor 21 is turned off. The electric telescopic rod 13 is started to drive the fixed plate 14 to move downward, so that the two pressing plates 16 are pressed against the surface of the polyimide film respectively. At the same time, the electric telescopic rod 13 continues to descend, and the pressing plate 16 compresses the compression spring 17, so that the pressing plate 16 is always pressed against the surface of the polyimide film. At the same time, the cutter 18 contacts the polyimide film to cut the polyimide film. During the cutting process, due to the action of the pressing plate 16, the shaking of the polyimide film is avoided, thereby ensuring the cutting quality.
