Description

[Technical field]

[0001] The invention relates to the technical field of plastic powder production equipment, in particular to an anti-adhesion plastic powder extrusion molding device. [Background technology]

[0002] At present, after the two extrusion barrels in the extrusion molding device have been working for a period of time, the temperature of the extrusion barrels will gradually increase. When the extrusion barrels extrude powder, the powder's bonding softening temperature is 40-50°C. If the extrusion continues, the powdery objects will bond and then bond to the surface of the extrusion barrel, affecting the extrusion effect.

[0003] Powder coating is a kind of formula material with synthetic resin as base material, pigment and filler. It is a new type of decorative material that has developed rapidly in recent years. It has the characteristics of energy saving, low pollution, high efficiency and high performance. The plastic powder production line usually includes an extruder, an extrusion component and a conveying component. The raw materials are heated and mixed inside the extruder to form a viscous state, and then conveyed out through the screw inside the extruder. The material conveyed from the extruder falls into the gap formed by the two extrusion rollers and is pressed into a sheet by the extrusion rollers. The extruded sheet falls into the conveying component for cooling and then conveyed to the next step.

[0004] Since the bonding softening temperature of the powder is 40-50℃, if the temperature is too high, the powdered object will stick together and then stick to the surface of the extrusion barrel, affecting the extrusion effect; if the temperature is too low, it will also affect the extrusion effect. After the extrusion is completed, the molded material needs to be cooled and then cut. However, it is often cut before it is completely cooled, which reduces the quality of the material and affects work efficiency. [Summary of the invention]
