[0002] With the rapid development of the plastic products industry, PET plastic bottles are more and more widely used in daily life and industrial production. However, in the processing of PET plastic bottles, the grinding of the bottle mouth is an important link. The existing PET plastic bottle mouth grinding equipment is usually composed of a workbench, a grinding device and a clamping device. When in use, the plastic bottle is placed vertically on the workbench, and then the plastic bottle is fixed on the workbench by the clamping device, and then the grinding device is started to grind the plastic bottle mouth. Although this type of device can complete the plastic bottle mouth grinding work, when the device works on some plastic bottles with softer bottle bodies, the clamping device may cause the plastic bottle to deform, thereby affecting the product quality and appearance, and reducing the practicability of the device to a certain extent. In order to solve the shortcomings of the prior art, we propose a bottle mouth grinding device for PET plastic bottle processing. Utility Model Content
