[0028] Specifically, the first electric push rod 23 can drive the mounting frame 22 to move downward, so that the winding roller 21 can approach the side surface position of the SMC sheet, the motor 24 can drive the winding roller 21 to rotate, so that the suction block 28 is pressed and sucked on the side surface of the SMC sheet, then the first electric push rod 23 moves the mounting frame 22 upward to tear and open the film on the side surface, the movable block 26 slides in the movable groove 25 to extrude the first support cylinder 27, so that the suction block 28 is elastically sucked on the film on the side surface of the SMC sheet, and the film on the side surface of the SMC sheet is torn and wound.

[0029] As Figures 2 to 5As shown, the auxiliary assembly 3 includes a cutting knife 31 movably sleeved on the side of the winding roller 21, and the cutting knife 31 covers the side of the winding roller 21. The cutting knife 31 is an "L"-shaped blade with a circular groove on the side. A bearing 32 is penetratingly arranged in the inside of the mounting frame 22. The bearing 32 is a bearing with a ball inside that can freely rotate. A second electric push rod 33 is penetratingly and fixedly arranged in the inside of the bearing 32, and the output end of the second electric push rod 33 faces the center position of the winding roller 21. A friction block 34 is fixedly arranged on the output end of the second electric push rod 33, and the friction block 34 is movably sleeved on the side of the winding roller 21. The friction block 34 is a circular block of wear-resistant material.
