Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of grinders, and in particular to a decoration grinder. Background Art

[0002] Decorations generally refer to items such as badges, medals, tags, and nameplates. After being painted with enamel (imitation enamel), current decorations on the market typically require grinding and polishing to ensure the metal lines are shiny, clean, and level with the enamel, ready for electroplating. The polishing process currently includes water grinding, cleaning and drying, rough polishing, and fine polishing.

[0003] Water Grinding: Currently, there are dedicated water grinders, primarily used to deburr the surface of painted enamel (imitation enamel) ornaments and smooth the metal and enamel surfaces. The process involves placing the ornament in a dedicated Bakelite jig. The sanding belt then abrades the surface by moving the ornament left and right, forward and backward. While abrading, the product is constantly flushed with water. This not only cools the product but also removes the dust created by grinding, preventing further scratches on the ornament. Currently, water grinding uses specialized jigs, and because the processing benchmarks vary, each jig has different thicknesses and parallelisms. This adjustment of the equipment is required with each product change.

[0004] Cleaning and drying: After rinsing the water-polished decorations, dry them and prepare them for the next step.

[0005] Rough polishing: Most of the time it is done manually, using a hemp wheel to polish off the exposed metal sand marks on the front of the decoration.

[0006] Fine polishing: Most of the work is done manually, using a cloth wheel to further polish the metal on the front of the decoration and remove dirt from the surface of the enamel (imitation enamel), making it smooth and flat, so that the decoration can be electroplated.

[0007] Based on the above reasons, the present invention proposes an ornament grinding machine. Utility Model Content
