Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder coating production, in particular to a mixing device for plastic powder coating production with a clogging prevention function. Background Technique

[0002] Plastic powder coating is a thermosetting powder coating for electrostatic spraying. After being heated at high temperature, the powder is sprayed onto the surface of the material by compressed air to form a firm, beautiful and corrosion-resistant coating. Under the action of the electrostatic field, the plastic powder is adsorbed onto the surface of the material to be sprayed, and then through heating and curing, the coating is tightly combined with the substrate.

[0003] In the preparation process of plastic powder coating, when the uniformly mixed coating flows through the discharge pipe, it is often easy to adhere to the inner wall of the pipe. This phenomenon not only aggravates the accumulation and adhesion in the discharge pipe, but also greatly hinders the smooth discharge of the coating, affecting the continuity of the discharge and the overall production efficiency. More seriously, in the long run, this clogging problem may lead to a sudden interruption of the production process, posing a direct threat to the stable operation of the production line, and thus affecting the output and quality of the product.
