Paint-spraying device

Abstract

The present invention discloses a kind of paint-spraying equipment. It includes spray gun, recovery device and spray-coating base seat. Said spray gun is placed on a mobile platform, said recovery device is placed under the spray gun, and has a containing space, on said recovery device an inlet and an outlet are set, the described inlet and outlet can be used for injecting and recovering solvent. Said spray coating base seat is placed in the containing space of said recovery device, on it a baseplate to be sprayed can be set.

Description

【Technical field】 [0001] The invention relates to a painting device. 【Background technique】 [0002] Paint spraying is to spray the paint liquid in the spray gun by air pressure, atomize it through the nozzle, and then apply it to the spray substrate. In order to achieve high gloss and scratch resistance on the surface, the surface of the mobile phone or computer casing is usually treated with spray paint. The composition of the paint can be roughly divided into two layers, the primer layer mixed with pigments and the transparent layer covering the primer layer. The topcoat layer, after painting, is hardened by heating or exposing it to ultraviolet light. [0003] In the prior art, the paint is usually uniformly mixed (including solvent, main agent and other additives), and then sprayed onto the substrate to be sprayed with a spray gun. Therefore, the amount and uniformity of the paint sprayed will affect the appearance and texture of the surface when it is finally hardened...

Problems solved by technology

[0003] In the prior art, the paint is usually uniformly mixed (including solvent, main agent and other additives), and then sprayed onto the substrate to be sprayed with a spray gun. Therefore, the amount and uniformity of the paint sprayed will affect the appearance and texture of the surface when it is finally hardened. When the substrate area is small, such as mobile phone panels, there will be a large amount of paint that is not sprayed on the substrate, resulting in waste, and the existing paint spraying device cannot effectively control the uniformity of spray paint and effectively recover the paint that is not sprayed on the substrate

In addition, during the initial research and development process in the laboratory, the spray gun is usually manually operated to spray paint. However, the spray quality of this spraying method often depends on experience, and it is difficult to achieve the same result for each experiment. The yield control extremely difficult
