Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a device for grinding the edges of plastic injection molded parts. Background Technology

[0002] Plastics processing, also known as plastic molding, is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector within the plastics industry. Plastics processing generally includes plastic batching, molding, machining, joining, finishing, and assembly. The latter four processes are carried out after the plastic has been molded into finished or semi-finished products, and are also known as secondary plastic processing.

[0003] After demolding, plastic injection molded parts will have excess plastic residue on the edges. When this excess plastic is directly sanded, it will not only generate a lot of dust, but the surface of the plastic injection molded parts will also be rough and require secondary processing. Therefore, a plastic injection molded part edge sanding device is proposed. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a device for grinding the edges of plastic injection molded parts. It has the following beneficial effects:

[0015] 1. This plastic injection molded part edge grinding device starts the adjusting motor to drive the adjusting gear to rotate, which in turn drives the linkage ring to rotate. The rotation of the linkage ring causes the angle adjusting gear to rotate, which changes the tilt angle of the grinding cutter. By starting the grinding motor, the end plate is rotated, which causes the grinding cutter to rotate and grind the plastic workpiece. This achieves the effect of eliminating residual glue on the edge through cutting, and solves the problem of rough surface after grinding.

[0016] 2. This plastic injection molded part edge grinding device uses a dust extraction air pump to generate suction in the collection cage, causing the grinding blade to cut the injection molded part. Powder and slag are sucked in through the gaps in the collection cage and collected inside the collection chamber through the connecting pipe. The grinding blade cuts the debris, which then enters through the gaps in the one-way plate, preventing the debris from scattering. This achieves the effect of collecting and storing debris, solving the problem of generating a large amount of dust particles after workpiece processing. Attached Figure Description
