Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a double-sided polishing device for a light-guiding acrylic plate. Background Art

[0002] Acrylic plate polishing is a common surface treatment method used to improve the gloss and transparency of acrylic plates. Through polishing, the surface of the acrylic plate can be made smoother and more uniform, and scratches and blemishes on the surface can be removed to make it look clearer and more transparent. Acrylic plate polishing usually uses grinding and polishing tools such as sandpaper, abrasives and polishing machines. First, the surface of the acrylic plate needs to be frosted with coarser sandpaper or abrasives to remove the roughness and scratches on the surface. Then, gradually use finer sandpaper or abrasives to polish until the desired smoothness and glossiness are achieved. However, the existing double-sided polishing device for light-guiding acrylic plates still has certain defects, such as:
