[0017] like Figure 1-3 As shown, the quick-release film tearing and winding mechanism includes a central shaft 1, a left clamping structure 2, a right clamping mechanism 3 and a winding drum 7. The left clamping structure 2 and the right clamping mechanism 3 have the same structure and are arranged opposite to each other. The left clamping structure 2 includes an adjusting wheel 4 and a clamping plate 5. The adjusting wheel 4 is fixedly connected to the clamping plate 5 through a plurality of connecting plates. The middle of the adjusting wheel 4 and the middle of the clamping plate 5 are respectively provided with a central hole 6 for the central shaft 1 to pass through. The inner side of the clamping plate 5 is provided with an annular platform 8. The winding drum 7 is located between the left clamping structure 2 and the right clamping mechanism 3. The annular platform 8 is inserted into one end of the winding drum 7. The central shaft 1 passes through the winding drum 7. The two ends of the central shaft 1 are respectively provided with threaded parts. The outer side of the left clamping structure 2 and the outer side of the right clamping mechanism 3 are respectively provided with limiting nuts 9. The limiting nuts 9 are respectively threadedly connected with the threaded parts. The winding drum 7 is clamped between the left clamping structure 2 and the right clamping mechanism 3, and the left clamping structure 2 and the right clamping mechanism 3 are fixed by the limiting nuts 9. The winding drum 7 is brought close to the film to be torn off, and the winding drum 7 is rotated so that the film is torn off and wound around the winding drum 7 .

[0018] Further, an adjusting screw hole is provided on one side of the limit nut 9, the adjusting screw hole is connected to the interior of the limit nut 9, a screw rod 10 is threadedly connected to the inner thread of the limit nut 9, and a bend plate 11 is fixedly connected to the screw rod 10.

Common components such as the bracket, motor and cylinder are not shown in the drawings of the specification. The cylinder drives the bracket to descend, driving the winding drum 7 to descend, so that the surface of the winding drum 7 contacts the release film to be torn off, and then the bracket rises to a certain height, so that the release film is peeled off from the material it covers. The central axis 1 rotates, and the release film is wound on the winding drum 7 in coordination with the movement of the material with the release film transported on the conveyor belt.
