AI Technical Summary
During the stirring process of the existing additive mixing device, due to the wide distance between the stirring blades, the stirring efficiency is low, and the particles cannot get good stirring, resulting in uneven mixing.
An additive mixing device including a stirring shaft and a stirring blade is designed. The stirring blades form a structure with a certain angle through the design of the center connecting sleeve, slot and insert block, ensuring that each layer of blade has no spacing and passing through the blades. Through holes allow the additive to move during rotation, avoid being pushed in the same plane, and improve mixing efficiency.
The uniform mixing of additives is achieved, the mixing efficiency is improved, and the additives at each position can be fully mixed, which improves the stirring efficiency.
