Description

Technical Field

[0001] The utility model relates to the technical field of capacitor production and processing, in particular to capacitor sandblasting equipment. Background Art

[0002] Capacitor sandblasting is a process for treating the surface of capacitor plastic cases. Sandblasting uses the impact of a high-speed sand stream to clean and roughen the surface of the substrate. For capacitor plastic case sandblasting, sand particles (such as quartz sand, corundum sand, etc.) are sprayed onto the surface of the capacitor plastic case at a certain pressure and speed through a spray gun. The high-speed impact of the sand particles removes dirt, burrs, grease, oxide layers, and other impurities from the surface of the plastic case, while also creating microscopic unevenness on the surface of the plastic case, increasing the surface roughness. When the capacitor plastic case needs to be subsequently painted, printed, or labeled, the roughened surface after sandblasting provides a better adhesion base for the coating or logo. For example, when printing a logo on the capacitor plastic case, the sandblasted surface allows the ink to penetrate and adhere better, preventing the logo from easily falling off during use.

[0003] There are few existing spraying devices specifically for capacitors, and their adaptability to products such as capacitors is poor. It is difficult to ensure that all surfaces are completely sandblasted during the sandblasting process, thereby failing to guarantee product quality. In response to the above problems, the present invention provides a solution. Utility Model Content
