[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastic. They include all products manufactured using plastic as a raw material, such as injection molding and vacuum forming. Plastic is a type of synthetic polymer material with plasticity. Plastic products need to be polished to enhance their appearance, which requires the use of polishing equipment.

[0003] A search revealed a rapid grinding device for plastic products disclosed in application number 202123278387.1. This device includes a base plate with a groove on its upper surface. A second motor is positioned above the base plate, with a rotating shaft mounted on the output end of the second motor and a grinding wheel mounted on the other end of the shaft. A fixing mechanism is located on the lower surface of the second motor and is used to fix the plastic product to be ground. The second motor is connected to an external power source. The plastic product is placed inside the groove, and then the second motor is started. The second motor drives the rotating shaft to rotate, which in turn drives the grinding wheel to rotate, thus grinding the plastic product placed in the groove. During grinding, the fixing mechanism secures the plastic product, preventing it from sliding and affecting the grinding process. Therefore, by setting up the fixing mechanism, it is easy to quickly fix the plastic product, effectively improving work efficiency.

[0004] However, the above method still has the following drawbacks in actual use: it uses a single grinding wheel to grind plastic products, but the grinding effect on plastic products is not good, it is difficult to grind them thoroughly, and it is easy to create grinding dead corners.
