After the motor 31 is started, the output end of the motor 31 drives the rotating shaft 32 to rotate through the coupling. During the rotation of the rotating shaft 32, the scraper 372 is driven to push the material on the top of the blanking baffle 36, and the material is pushed into the dissolving tank 2 through the hole at the top of the blanking baffle 36.

After the mixture inside the dissolving tank 2 is stirred for a period of time, the valve of the pipe 3 62 is opened to allow the mixture to enter the protective shell 63 through the pipe 3 62 and be sent back to the space above the inner cavity of the dissolving tank 2 through the rotating shaft 2 64 and the auger blade 65 through the return pipe 61 for a secondary mixing and dissolving operation. Finally, the valve at the pipe 3 62 is closed and the valve at the discharge pipe is opened to collect the finished powder coating product.
