Description

Technical Field

[0001] The utility model relates to the technical field of plastic box production, in particular to an edge and corner grinding mechanism for plastic box blow molding production. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material, including products made of injection molding, blister molding and other processes. Plastic is a type of synthetic polymer material with plasticity. It, along with synthetic rubber and synthetic fiber, forms the three major synthetic materials that are indispensable in daily life.

[0003] At present, due to the special production process of plastic boxes, they generally need to be polished during the production process to remove burrs, protrusions and other uneven parts on the surface. In the Chinese patent document with authorization announcement number CN218316019U, "A polishing device for plastic water tank processing", the water tank is clamped on a three-jaw chuck by a rotating disk. When the water tank needs to be turned over, the plug is pulled to disengage the plug from the slot, so that the water tank can be turned over and the other surfaces of the water tank can be polished. The burrs and dust after polishing fall into the collection tank, and the dust in the collection tank is discharged by an auger, thereby facilitating the polishing of the water tank.

[0004] However, this device still has some defects in actual use. For example, it can only grind a single plane during grinding, and the processing effect on corners is poor, resulting in low quality of the finished product after grinding and many burrs. Therefore, there is an urgent need for a corner grinding mechanism for plastic box blow molding production. Utility Model Content
