AI Technical Summary
Existing plastic film cutting devices are prone to causing wrinkles in the film material during the cutting process, affecting the flatness of the cut end face, and debris may remain on the film material after cutting, affecting its use.
An electric actuator is used to lower the lifting plate, which in turn presses the hollow plate against the plastic film. A dual-axis motor drives a lead screw slider to move the cutting blade, which counteracts the pulling force. At the same time, a fan generates negative pressure to remove debris and dust.
This effectively prevents wrinkles from appearing after the plastic film is cut, ensures that the cut end is flat, and removes debris and dust from the surface of the film, thus improving the quality of the film.
