Description

Technical Field

[0001] This utility model relates to the field of edge grinding technology, specifically to an edge grinding device for plastic products. Background Technology

[0002] Plastic products are a general term for various products made from high molecular polymers through processing techniques such as injection molding, blow molding, extrusion, and compression molding. Due to their lightweight, durability, low cost, and high plasticity, plastics are widely used in daily life and industrial fields.

[0003] After production, plastic products need to be polished by an edge grinding device to improve their quality. However, most existing edge grinding devices rely on manual material cutting, which is not only inefficient and difficult to meet the needs of large-scale production, but also prone to errors due to human fatigue, which can lead to deviations in the material cutting position and damage to the plastic products. Therefore, an edge grinding device for plastic products is proposed to solve the above-mentioned problems. Utility Model Content

[0044] Working principle:

[0045] Step 1: Place the plastic cover 5 to be polished on the base 303, start the electric push rod 301, the electric push rod 301 drives the pressure block 302 to descend, pressing and fixing the plastic cover 5. At the same time, start the motor 307, the motor 307 drives the second gear 309 to rotate through the planetary reducer 308. The second gear 309 meshes with the first gear 306, so that the rotating shaft 305, the support block 304, the base 303 and the plastic cover 5 rotate together.

[0046] Step 2: Start the drive mechanism inside the moving block 202. The moving block 202 moves along the track 201, driving the grinding robot 203 to move to the appropriate position to grind the edge of the rotating plastic cover 5. The debris generated during the grinding process is scattered on the bottom wall of the inner cavity of the outer shell 1.

[0047] Step 3: After grinding, start the pneumatic jet 401. The pneumatic jet 401 sprays high-pressure gas to blow the plastic cover 5 away from the clamping mechanism 3. Under the action of gravity, the plastic cover 5 and the debris slide down along the guide block 402 and the screen 403 respectively. The debris falls into the collection block 405 through the screen 403, and the plastic cover 5 is discharged through the discharge hole 410. When it is necessary to clean the collection block 405, pull the handle 408 to make the clamp 407 disengage from the slider 404, and then take out the collection block 405 for cleaning.
