Abstract

The invention discloses a paint powder grinding tool which comprises a mixing barrel and a sealing cover, wherein the sealing cover is movably connected with the mixing barrel; a fixing device used for fixing the sealing cover is arranged on the mixing barrel; a grinding piece is arranged at the bottom of the mixing barrel; the grinding piece is connected to a driving device used for driving the grinding piece to rotate; the driving device is positioned outside the mixing barrel; two corresponding edges of the grinding piece are knife-edge-shaped, and one edge is attached to the bottom of the mixing barrel; an included angle between the grinding piece and the bottom of the mixing barrel is larger than 20 degrees and smaller than 45 degrees; a powder discharging device is arranged on the mixing barrel. The paint powder grinding tool has the advantages that the structure is simple, and the powder grinding fineness can be effectively improved.

Description

technical field [0001] The invention relates to the field of paint powder production and processing devices, in particular to a paint powder grinding tool. Background technique [0002] Paint is composed of resins, solvents, pigments, additives, etc. In the current production process of paints and coatings, the raw materials will be melted and mixed according to a certain proportion, then pressed into tablets and cooled, and then ground. The ground powder can be further processed into paint. coating. Fineness is one of the important intrinsic qualities of paints and coatings. It has a great influence on film quality, film gloss, durability and storage stability of coatings. When it is ground, it uses a grinder for grinding, but this method has a problem, that is, during the grinding process, the fineness of the particles is not ground enough, which affects the quality of the finished product of the paint coating. Contents of the invention [0003] The technical problem ...
