Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder screening, in particular to a multi-stage screening device for plastic powder production. Background Art

[0002] Powder coating is a formula material with synthetic resin as the base material, combined with pigments and fillers. 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. As a solvent-free coating, it has high coating efficiency, good anti-corrosion performance, can form a film in one time and is easy to store and transport. It is becoming increasingly popular. Thermoplastic powder coating is obtained by dry mixing or melt mixing, crushing, screening and grading of thermoplastic resin, pigments, fillers, plasticizers and stabilizers.

[0003] The current multi-stage screening device for screening plastic powder has different sizes after being crushed. If the plastic powder is not screened in multiple stages, the overall quality of the plastic powder will be affected. However, in the process of screening the plastic powder, the scraper structure is easily stuck by the plastic powder, and the stuck scraper structure is difficult to adjust, resulting in a poor service life of the scraper structure, so that the entire scraper structure needs to be replaced, which is not economical and practical. In addition, after the plastic powder is screened, it is difficult for the plastic powder to be automatically discharged from the box, thereby reducing the discharge efficiency. For this reason, we propose a multi-stage screening device for plastic powder production to solve the above-mentioned technical problems. Utility Model Content
