Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Examples

Referring to the attached drawings 1 and 2, the cutting and rolling machine for the PU adhesive protective film in the embodiment includes a frame 1, one end of the frame 1 is connected with a cabinet 2, a rotating mandrel 4 driven by a first motor 3 is arranged on the frame 1, and the rotating mandrel 4 is arranged along an X-axis direction and used for placing a product to be cut. Two sides of the rotating mandrel 4 are provided with fixing rings 5, the positions of the products to be cut placed on the rotating mandrel 4 are limited by the fixing rings 5, and the position deviation of the products to be cut in the cutting process is reduced or avoided.

Be equipped with cutting platform 6 on frame 1, last linear electric motor 7 and the linear guide 8 of placing along the X axle direction of being equipped with of cutting platform 6, it is equipped with loading board 9 to slide on the linear guide 8, loading board 9 links to each other with linear electric motor 7's active cell for loading board 9 round trip movement under linear electric motor 7's drive. And a cutter mechanism is arranged on the bearing plate 9. The cutter mechanism comprises a cutter frame 10 capable of moving back and forth along the Y-axis direction, and a circular cutter 11 driven by a second motor is arranged on the cutter frame 10.
