AI Technical Summary
During the cutting process of plastic film, the film is prone to wrinkles and displacement due to external forces, resulting in a decrease in cutting quality.
A slitting machine for plastic films is designed, using an inclined film laying mechanism and a positioning and compression mechanism. The inclined film laying mechanism automatically flattens the film through the inclined state of the angle adjustment pallet, and the positioning and compression mechanism prevents the film from shifting or wrinkling during the cutting process through the cooperation of the anti-slip strip and the compression plate.
Through the automatic flattening function of the inclined film laying mechanism and the compression treatment of the positioning and compression mechanism, the plastic film is effectively prevented from displaced or wrinkled during the cutting process, improving the cutting quality.
