Description

Technical Field

[0001] The utility model belongs to the technical field of coating grinding, and in particular relates to a coating grinding mechanism. Background Art

[0002] Paint, traditionally known as paint in China, is a viscous liquid coated on the surface of an object to be protected or decorated, and can form a continuous film that is firmly attached to the object. It is usually mainly resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. Before using the paint, the raw materials of the paint need to be processed and ground.

[0003] The existing patent number is: CN 220496453 U. A paint stirring and grinding mechanism grinds the material through the grinding layer on the outer wall of the grinding rod. After the material is ground, it falls to the bottom of the grinding tank and falls into the mixing barrel from the connecting pipe.

[0004] Due to the utility model, in actual use, the paint is easy to adhere to the grinding roller after grinding, and will not drip until it accumulates to a certain amount. The ground paint is easy to be brought to the top of the grinding roller again, affecting the grinding efficiency. At the same time, there is a lack of filtering mechanism. When the ground paint is directly mixed and stirred, it affects the paint quality. When the filter is installed directly under the grinding bucket, larger particles are easy to accumulate above the filter, affecting the filtration speed. Utility Model Content
