Description

Technical Field

[0001] The utility model relates to the technical field of powder coating processing, in particular to a high-precision grinding device for thermosetting powder coating. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.

[0003] However, there are many existing technologies, such as a high-precision grinding device for thermosetting powder coatings disclosed in publication number CN219210137U. The technology includes a grinding box, an adjustment component, a drive component, a grinding component and a leak-proof component. An equipment table is welded on the top peripheral side wall of the grinding box, and the upper side wall of the equipment table is connected to the drive component through a support arm. An adjustment component is inlaid on the inner wall of the grinding box, and a grinding component is installed inside the grinding box. A leak-proof component is installed at the bottom center of the grinding box. The technology can grind the coating raw materials put into the grinding box through the mutual cooperation of the adjustment component and the grinding component. At the same time, the cooperation of the leak-proof component can improve the sufficiency of the raw material grinding, and the fineness of the grinding can be achieved by replacing the grinding plates with different particle sizes. However, there are the following problems in use:

[0004] The above technology cannot stir the heat-fixing powder when grinding the thermosetting powder coating, resulting in that during grinding, by placing the grinding block in the grinding groove, only the lower end of the grinding block can be effectively ground. During grinding, part of the heat-fixing powder coating will be squeezed to the upper end of the grinding groove, resulting in the inability to grind the heat-fixing powder coating squeezed to the upper part of the grinding block, resulting in uneven grinding. When the powder coating is used to paint the outer or inner walls of a building, it is easy to cause uneven painting. Utility Model Content
