When it is necessary to stop winding the plastic film, the lifting cylinder drives the cutting knife to move towards one side of the driving roller, so that the cutting knife touches the plastic film and cuts a part of the plastic film. Finally, the moving piece drives the connecting rod to move along the horizontal direction of the mounting frame, thereby cutting the plastic film. The above operation does not require the staff to manually cut the plastic film, thereby effectively improving the work efficiency of the staff.
