Powder-spraying and paint-spraying single-line spray system and process

Abstract

The invention relates to the technical field of coating, and discloses a powder-spraying and paint-spraying single-line spray system. The powder-spraying and paint-spraying single-line spray system comprises a gluing chamber, a colored paint spraying chamber, a leveling chamber I, a clear lacquer spraying chamber, a leveling chamber II and a drying chamber, which are sequentially arranged, and further comprises a mobile powder room, wherein an opening for allowing the mobile powder room to get in and get out is formed in the leveling chamber II; and an opening-closing device is corresponding to the opening. The system can realize powder-spraying and paint-spraying on a single production line. In the meantime of achieving advantages of zero VOC emission and low input of powder spraying, requirements for spraying in different colors for work pieces can be met conveniently by utilizing an advantage that multi-color spraying can be realized by utilizing paint spraying, and the cost is reduced. The invention further provides a powder-spraying process and a paint-spraying process. The powder-spraying process comprises the steps of gluing, carrying out powder-spraying pretreatment, carrying out powder-spraying, drying and the like; and the paint-spraying process comprises the steps of gluing, spraying colored paint, carrying out primary leveling, spraying clear lacquer, carrying out secondary leveling, drying and the like. The powder-spraying process and the paint-spraying process can be carried out on the same production line, and are convenient in coating.

Description

technical field [0001] The invention relates to the technical field of painting, in particular to a co-linear spraying system and process of powder spraying and paint spraying. Background technique [0002] Powder coatings have the advantages of low equipment investment and zero VOC (volatile organic compound) emissions, and are widely used in the home appliance industry. However, due to the difficulty in color change and the difficulty in controlling the appearance quality, they are rarely used in vehicle spraying. [0003] At present, people are beginning to try to apply powder spraying to the coating of the car cabin, but generally only one or two colors can be sprayed. accomplish. If you want to spray the appearance color of metallic paint, you need to build a new spraying production line, which cannot be shared with the powder spraying line, and the investment cost is relatively high. [0004] Therefore, those skilled in the art need to redesign the powder spraying pr...
