Description

Technical Field

[0001] This utility model relates to the field of water-based paint production and preparation technology, specifically to a water-based paint grinding and mixing machine. Background Technology

[0002] A water-based paint grinding and mixing machine is a specialized device for controlling particle size distribution, homogenizing the system, and improving dispersion stability in water-based coating systems. It typically integrates grinding, mixing, dispersion, thickening, and grading functions. Its core function is to efficiently disperse and refine solid particles in the liquid phase, reducing agglomeration and improving the coating's gloss, hiding power, water resistance, abrasion resistance, and film thickness uniformity. Currently, water-based paint raw materials undergo mixing and grinding within the grinding and mixing machine. Because this is a mature technology with the advantage of integrated operation for both grinding and mixing, it offers significant improvements in water-based paint production. However, particulate matter in the water-based paint raw materials can easily enter the grinding and mixing machine, sometimes falling to the bottom and preventing further processing. In cases of grinding, the uniformity of water-based paint raw materials with larger particles is affected during mixing, resulting in slower mixing. Furthermore, during the grinding process, the water-based paint raw materials are easily pressed by the grinding rollers and adhere to the surface of the pressed parts, which also leads to unevenness of the water-based paint raw materials after grinding and mixing. This seriously affects the final quality of the water-based paint after preparation. Moreover, the subsequent cleaning is also difficult due to the influence of the grinding and mixing machine itself, thus reducing the effectiveness of the water-based paint grinding and mixing machine and the quality of the mixed material.

[0003] In conclusion, it is necessary to invent a water-based paint grinding and mixing machine. Utility Model Content

[0012] Preferably, a grinding roller is installed at the bottom of the bracket, and a brush plate is installed above the grinding roller.

[0013] The beneficial effects of this utility model are: In this invention, water-based paint raw materials enter the grinding frame, and are ground by grinding rollers on multiple supports driven by a motor until they pass through the grinding rollers. During grinding, the brush plate above the grinding rollers contacts the outer wall of the grinding rollers, cleaning up the powder adhering to the outer wall and minimizing the impact of water-based paint raw materials adhering to the outer wall on the subsequent mixing uniformity. At the same time, water-based paint raw materials entering the mixing tank are first blocked by the grinding frame to prevent them from falling into the mixing tank and causing uneven mixing due to lack of grinding. This effectively improves the performance of the water-based paint grinding and mixing machine and also improves the quality of water-based paint production. Attached Figure Description
