Anti-sticking cooling device for production of plastic powder coating
This invention relates to the field of powder coating production technology and discloses an anti-adhesion cooling device for powder coating production. In this invention, a corresponding conveying component is placed inside the external frame. An auxiliary spring-loaded assembly, consisting of a guide groove, pressure rod, connecting shaft, and return spring, allows a soft pad placed on its side surface to intermittently contact the material on the bottom conveyor belt at appropriate times. Even after cooling, the coating material that remains adhered will partially break off under the contact of the soft pad. The spring-loaded contact of the soft pad relies mainly on the interaction between the contact rod, connecting sleeve, abutment rod, and return spring connected to the other end. This device separates material that remains adhered after cooling under mechanical stress; the overall structure is simple and easy to operate.
