[0008] The polishing belt assembly includes rotating shafts mounted on the left and right sides of the worktable. One of the rotating shafts is connected to a drive motor. Several insertion adjustment holes are opened from front to back on the inner side of each rotating shaft on the upper surface of the worktable. A tension adjustment roller is installed in one of the insertion adjustment holes through an insertion rod. A polishing belt is wound on the two rotating shafts and the two tension adjustment rollers. One side of the polishing belt is fitted against the edge of the plastic part.

[0009] Dust collection boxes are located on both the front and rear sides of the workbench, below the grinding belt.

[0010] The dust collection box has a dust collection pipe and a dust collection fan connected to its side wall, and a trap is installed on the inside of the dust collection pipe on the side wall of the dust collection box.

[0011] The beneficial effects of this utility model are: it can simultaneously grind the edges of multiple plastic products, the plastic product clamping and fixing components are easy to assemble and disassemble, the position of the grinding belt can be adjusted according to the product width, and it can adapt to the grinding of products of different widths, thus having higher adaptability.
