Background

In the production process of coating materials, the mixing of raw materials is a crucial link, and the uniformity and efficiency of the mixing directly affect the quality and performance of the final coating material. Conventional raw material mixing apparatuses generally have only a simple stirring function, however, these conventional apparatuses gradually expose a number of problems in practical use.

Firstly, during the raw material adding process, raw materials tend to flow into the mixing container from the storage container in a concentrated manner, and even distribution is difficult to realize, which can lead to the situation that local concentration of the raw materials is uneven at the initial stage of mixing, thereby influencing the subsequent overall mixing effect. Different coating materials have different physical and chemical properties, such as pigments with different particle sizes, resins with different viscosities, various auxiliary agents and the like, and if the materials cannot enter a mixing container uniformly, local agglomeration or layering phenomenon can be formed in the mixing process, so that indexes such as color uniformity, film coating performance and the like of a final product are affected.

Second, conventional devices lack effective solutions to the problem of sticking to the inside walls of the mixing vessel. In the stirring and mixing process of the coating material raw materials, the coating material raw materials are easy to adhere to the inner wall of the mixing barrel due to the viscosity or other physical and chemical characteristics of the coating material raw materials, especially the inner wall at the bottom and the middle of the mixing barrel, and the long-term accumulated adhesion substances can influence the mixing quality of subsequent batches, so that frequent shutdown is required for cleaning, and the production efficiency is greatly reduced.

We have therefore proposed a raw material mixing device for coating material production in order to solve the problems set forth above.
