For example, a Chinese invention patent with publication number CN115303655B proposes an intelligent storage device for powder coating. The storage device realizes quantitative storage of powder coating by providing a quantitative storage component, a stirring component and a scraper component to avoid excessive accumulation and agglomeration of powder coating. At the same time, the stirring component is used to stir the powder coating regularly to prevent it from being stacked statically for a long time, which causes the agglomeration of the lower layer of powder coating. The scraper component is used to scrape off the agglomerated powder coating in the lower layer to avoid further agglomeration.

[0003] The stirring component of the above-mentioned existing powder storage device is located at the bottom of the metal powder pile or the ceramic raw material powder pile. Since the density of the metal powder or the ceramic raw material powder is very large, when the storage amount in the storage tank is large, the metal powder pile or the ceramic raw material exerts a huge pressure on the stirring component. In addition, the fluidity of the metal powder or the ceramic raw material powder is poor, resulting in a large resistance to the stirring component, thereby causing poor stirring effect and easy damage to the stirring component.
