Then, rotate the rocker arm 14 to drive the screw 13 to rotate. The rotation of the screw 13 can drive the limiting plate 83, the movable plate 5, the rotating rod 7, and the clamping plate 6 to move back and forth. When the clamping plate 6 moves to both sides of the scrap, rotate the rotating rod 7 to drive the clamping plate 6 to move inward to clamp and position the scrap. It has good adaptability. Then, by starting the first servo motor 2, the output end of the first servo motor 2 drives the transmission. The rod 3 and the cutting disc 4 rotate, and the electric push rod 92 is activated. The output end of the electric push rod 92 drives the mounting plate 93, the first servo motor 2, the transmission rod 3, and the cutting disc 4 to move downward, thus slicing the scrap material. Finally, the second servo motor 15 is activated, which drives the lead screw 16 to rotate. The rotation of the lead screw 16 drives the adjusting plate 12 and the bracket 91 to move left and right. The left and right movement of the bracket 91 drives the cutting disc 4 to move left and right, thus ensuring the flatness of the cut surface. At the same time, the collection box 10 can collect the debris generated during cutting, making it convenient for the user to clean up.

[0034] In summary, this cutting device for processing plastic scraps, by setting up a movable plate 5, a clamping plate 6, and a rotating rod 7, allows the movable plate 5 to limit the movement of the rotating rod 7. Rotating the rotating rod 7 can drive the clamping plate 6 to move inward to clamp and position the scrap. This solves the problem that existing positioning methods have poor adaptability, are difficult to meet the needs of plastic scraps of different sizes, and are prone to causing the scrap to shift or shake during cutting, resulting in uneven cuts after cutting.
