[0002] Plastic spraying is a surface treatment method in which plastic powder is sprayed on parts. Plastic spraying is what we often call electrostatic powder spraying. Its processing technology is a relatively common metal surface treatment decoration technology used internationally since the 1980s. Compared with ordinary spray paint surface treatment, this technology has the advantages of advanced technology, energy saving and high efficiency, safety and reliability, bright colors, etc. Therefore, it is often used in light industry and home decoration fields. Its working principle is to charge plastic powder through high-voltage electrostatic equipment, and under the action of the electric field, the paint is sprayed onto the surface of the workpiece. The powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; and the powdery coating will be leveled and solidified after high-temperature baking, and the plastic particles will melt into a dense final protective coating with different effects; firmly attached to the surface of the workpiece.

[0003] The existing technology has the following problems:

[0004] A large amount of plastic powder will be generated during the spraying process. In order to avoid affecting the health of workers, a plastic powder recovery device is generally provided to recover the plastic powder. However, the existing plastic powder recovery device has a simple structure and a single function, and is unable to perform deep processing on the recovered plastic powder, and has poor practicality.

[0005] To this end, we proposed a plastic powder recovery device for facade plastic spraying and lamination to solve the above-mentioned drawbacks. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model is provided with a device body, a rotating motor, a crushing box, a filter, a crushing roller, a crushing motor, a gear, a pretreatment box, a cooling pipe, a heat dissipation fan, a vacuum cleaner and a dust hood. When in use, circulating cooling water is injected into the cooling pipe, and then the recovery device can be started. The vacuum cleaner draws the plastic powder floating in the air into the pretreatment box through the dust hood, and the plastic powder is air-cooled by the heat dissipation fan and blown to the surface of the cooling pipe. The plastic powder is secondary cooled by water cooling to ensure the cooling effect of the plastic powder so that it can be crushed later. Then, the plastic powder enters the crushing box through the recovery pipe, and is crushed with the cooperation of the crushing motor and the gear, while the filter screen filters the crushed plastic powder. Then, the rotating motor is started, and the crushing box is adjusted to perform secondary crushing on the plastic powder to improve the crushing effect of the plastic powder so that the plastic powder can be recycled and reused later, thereby greatly improving the versatility of the device.

[0016] (2) The utility model provides magnets and magnetic balls. When the crushing box is adjusted, the magnets are away from the magnetic balls and cannot have a magnetic adsorption effect on the magnetic balls, which will cause the magnetic balls to block the recovery pipe. During the adjustment of the crushing box, the pre-treated plastic powder stays in the recovery pipe for a short time, preventing the plastic powder from being directly discharged into the device body, making it impossible to crush the plastic powder.
