Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, specifically to a high-efficiency surface polishing device for irregularly shaped sheets. Background Technology

[0002] In the production and processing of sheet materials, surface sanding of irregularly shaped sheets (such as curved or irregularly shaped sheets) is an important step. Traditional sanding equipment typically suffers from the following problems: 1) Irregularly shaped sheets are complex and difficult to stabilize with ordinary conveying devices, leading to easy displacement during sanding and affecting processing quality; 2) Existing equipment relies heavily on manual adjustment of the sanding head position and pressure, resulting in low efficiency and poor consistency; 3) Sanding dust is easily dispersed, and existing dustproof structures have poor sealing, posing a health hazard to workers; 4) Traditional support structures cannot flexibly adapt to different shaped sheets, and changing fixtures is time-consuming and labor-intensive.

[0003] While some improvements have addressed certain issues by adding dust collection devices or modifying the conveyor belt structure, a solution that integrates high-precision positioning, adaptive grinding, and efficient dust removal is still lacking; it cannot meet the demand for efficient and precise grinding of irregularly shaped materials.

[0004] The surface grinding device for irregularly shaped plates with application number CN202221291535.5 can only grind the workpiece once. After grinding, it needs to be manually replaced before grinding can continue, which is inefficient. Moreover, for grinding different workpieces, the corresponding template needs to be replaced, which prolongs the workpiece replacement time. In addition, for grinding the surface of irregularly shaped plates with different heights, the grinding head cannot be raised and lowered in real time. Therefore, it cannot meet the needs of efficient and precise grinding of irregularly shaped plates. Utility Model Content
