The trimming device for plastic product processing according to claim 8, characterized in that: A plurality of groups of the product racks (2) are installed side by side on the upper side of the base frame (1), and a plurality of groups of the product racks (2) are located below the clamp device (38).

10. A method for using a trimming device for processing plastic products, using the trimming device for processing plastic products as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1, stacking the disc-shaped plastic products to be trimmed in the middle of the product rack (2), sequentially controlling the first servo motor (32) and the first electric cylinder (36) to start, and the clamping device (38) moves downward to clamp a piece of the disc-shaped plastic products stacked in the product rack (2) and transfer it to the middle position on the upper side of the lower pressure rod (547); S2, controlling the movable rod of the second electric cylinder (541) to move downward, so that the upper pressing rod (546) and the lower pressing rod (547) limit the position of the disc-shaped plastic product; S3, starting the feeding assembly (51) and the traverse assembly (52), driving the disc-shaped plastic product to approach the abrasive belt (46), and synchronously controlling the fourth servo motor (551) to start, adjusting the contact range between the disc-shaped plastic product and the abrasive belt (46); S4, the second servo motor (43) is started, and the sanding belt (46) rotates in a taut state on the outer sides of the driving pulley (44) and the auxiliary pulley (45); S5, after the third servo motor (542) is started, it drives the upper pressure rod (546) to rotate after transmission, thereby driving the disc-shaped plastic product to rotate, and under the grinding action of the sanding belt (46), the arc surface of the disc-shaped plastic product is trimmed; S6. After the trimming is completed, the product is taken down by the product transfer mechanism (3) and transferred to an empty product rack (2).
