(2) According to the application, through the mode that the limiting opening 53 of the movable rod 52 is matched with the axially movable cutter 4, the function of synchronously adjusting the position of the anti-deflection rod 54 according to the width of the film 9 is realized, the problem that the deviation correcting component cannot be synchronously adjusted while the distance between the cutters is adjusted is solved, and the film cutting device has the characteristics of convenience in adjustment and good film cutting effect.
