[0030] The working principle of this embodiment is as follows: The base color powder and the metal pigment are respectively injected from the two feeding ports 24. At the same time, the motor 311 is started to drive the stirring paddle 33 to rotate slowly, that is, pre-mixing is carried out on the materials during the material injection stage. After the materials are injected, the motor 311 starts to operate normally. At this time, the spiral ribbon stirring blade 331 and the straight stirring blade 332 work together to realize the up and down stirring and the inside and outside stirring of the materials in the tank, making the materials more evenly mixed. When it is necessary to heat the materials, the electric heating device 4 is started, and the operation controller 41 is set to set the heating temperature. The electric heating tube 42 transfers the heat to the inside of the tank body 2 through the heat conduction layer 21 to heat the materials; after the metal powder coating is made, it is discharged from the discharge port of the tank body 2. Then, the cleaning device 5 starts to clean the tank body 2. The water pump 51 connects to convey the external water source and appropriately pressurizes it.
