However, the existing cutting method has very low working efficiency and poor precision, and the labor intensity of the workers is high, which cannot meet the production demand. Therefore, it is urgent to design a plastic sheet automatic cutting device. However, the existing plastic sheet automatic cutting device cannot clean the waste generated by cutting, has poor use effect, and adopts a cutting machine type. The plastic sheet cutting machine is a mechanical equipment for cutting plastic materials, mainly applied to the processing of various plastic sheets.
