Technical Field

[0001] The utility model relates to the technical field of plastic production, and more specifically to an automatic feeding device for a plastic color mixing machine. Background Art

[0002] The color mixer uses the high-speed vortex rotation of the material-dispensing blades to make the plastic particles (or resin powder) roll, collide, rub and generate heat at high speed, so that while the materials are mixed, the water evaporates quickly from the exhaust pipe to achieve the purpose of drying.
