Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder production, in particular to an automatic batching device for plastic powder production. Background Art

[0002] Plastic powder is the material for the plastic spraying process. Simply put, it is the plastic powder that is heated at high temperature and then sprayed onto the surface of the material through the wind provided by compressed air. Plastic powder and paint are two different processes. Plastic spraying has good effect, low cost, bright color and beautiful appearance. Paint is expensive and the effect is average. Polyester paint or fluorocarbon paint can have better effect. Doors and windows are generally used in environments with relatively low corrosion, and the sealing of plastic is sufficient. Paint is used in environments with high corrosion. Finally, the coating of the plastic-sprayed product is difficult to repair after being damaged, while paint is easier. Plastic powder is a thermosetting powder coating for electrostatic spraying. Plastic powder is a mixture of multiple materials, so when producing plastic powder, the materials need to be batched. The following defects or deficiencies exist in the use of the batching device:

[0003] 1. When cutting materials, they need to be configured according to the proportion, which is time-consuming and labor-intensive;
