Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder processing, in particular to a plastic powder extrusion molding device. Background Art

[0002] Plastic powder is the material for the plastic spraying process. Simply put, plastic powder is heated at high temperature and then sprayed onto the surface of the material through compressed air. Plastic powder and paint are two different processes. Plastic spraying has good effect, low cost, positive color and beautiful appearance. Paint is expensive and the effect is average. Polyester paint or fluorocarbon paint can have better effects. Doors and windows are generally used in environments with relatively low corrosiveness, and the sealing of plastic is sufficient.

[0003] According to the search, Chinese patent literature, announcement number: CN218519157U, discloses a plastic powder extrusion molding device. By rotating and unscrewing the material sealing cover, plastic powder is added to the plastic powder barrel, and then the model cover with the identification mark is rotated and sleeved on the extrusion barrel, the hand-held handle is held tightly, and then the material discharge switch is pressed to start the material discharge motor, and the material discharge motor automatically adds a certain amount of plastic powder to the inside of the extrusion barrel, and then the trigger is pulled by the finger, and the trigger rotates to make the pressing block contact with the motor switch. At this time, the extrusion motor starts, controls the first spiral pressing paddle to push the internal plastic powder to the model cover, and then continuously rotates through the pressing plate to grind the bottom surface of the pressing block, and the pressing plate and the model cover are used to shape the pressing block. However, the plastic powder extrusion molding device directly extrudes the plastic powder, but if the existing plastic powder material is not heated and melted, it will be difficult to form due to the large density between the plastic powders. Even if it is formed with a large pressure, it is very easy to become loose. Utility Model Content
