Description

Technical Field

[0001] This application relates to the technical field of powder spraying equipment, and more particularly to an automatically cleanable powder supply device and a powder supply management device. Background Technology

[0002] Powder coating production lines are widely used in the automotive, home appliance, electronics, construction, and transportation industries. In the construction industry, they are commonly used to manufacture curtain walls, ceilings, aluminum doors and windows, etc.; in the transportation industry, they are commonly used to manufacture the outer shells of vehicles such as automobiles, trains, and ships; and in the electronics and home appliance industries, they are commonly used to manufacture the outer shells of electronic products and home appliances.

[0003] Powder supply management equipment is an essential tool in powder coating production lines. It effectively connects a series of processes such as spraying, recycling, and powder supply, thereby giving the powder coating process higher efficiency.

[0004] In industrial production, existing powder supply management equipment cannot automatically clean the powder supply pipelines. Consequently, when changing to new powder coatings, it is necessary to spray out residual powder over a long period of time, and only after the residual powder is completely consumed can the new powder coating begin. This not only wastes time and reduces work efficiency, but also poses a risk of powder mixing, affecting the coating effect. Therefore, those skilled in the art urgently need to develop an automatically cleaning powder supply device to meet the needs of practical applications. Utility Model Content
