The output end of the first motor 15 drives the drum to rotate, the drum rotates to drive the rope 14 to rotate, the moving direction of the rope 14 is consistent with the rotating direction of the first motor 15, after the plastic film is collected, the first motor 15 drives the rope 14 to move, the rope 14 pulls the circular blade 22 to slide in the groove on the cutting table 5 and cut the plastic film, the upper end face of the dragging plate 12 is smooth, the machine works, the plastic film cannot be contacted with the circular blade, after cutting, due to the ductile effect of the plastic film, the plastic film possibly rebounds in the opposite direction after cutting, the plastic film needs to be wound on the recovery cylinder 4 again, time and labor are wasted, the plastic film can be in contact with the upper end face of the dragging plate 12 due to self gravity when rebounded, the plastic film can be adhered to the upper end face of the dragging plate 12, at this moment, the output end of the third motor 32 drives the second gear 31 to rotate, the dragging plate 12 moves towards the direction of the recovery cylinder 4 under the meshing effect of the first gear 17 and the second gear 31, then the plastic film can be wound on the recovery cylinder 4 more conveniently, and the plastic film can be wound on the recovery cylinder 4 again, the elastic film can be separated from the recovery cylinder 27 until the elastic film is recovered, and the elastic film is separated from the external surface of the recovery cylinder 4, and the elastic film is recovered from the recovery cylinder 4, and the elastic film is recovered.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
