Film cutting device

A film cutting device comprises a guide component, a moving mechanism and a cutting mechanism, the moving mechanism is arranged on one side of the guide component, the cutting mechanism is connected to the output end of the moving mechanism, the guide component is used for moving guiding of the cutting mechanism and feeding and retracting control of the cutting mechanism, and the moving mechanism is used for driving the cutting mechanism to move. And when the cutting mechanism moves, the film is transversely cut through the cutting mechanism. Compared with a traditional cutting device, the two-way cutting device has the advantages that a two-way cutting mode is adopted, in other words, when cutting operation is carried out, cutting operation can be carried out twice through one reciprocating motion, so that cutting efficiency of the optical thin film is improved, meanwhile, adaptive adjustment can be carried out according to the width of the optical thin film, the application range is widened, and the cutting
