Spraying production line

Abstract

The invention discloses a spraying production line, which is applicable to conducting spraying on a workpiece clamped on a workpiece holder and comprises at least one spraying line. The spraying line comprises at least two circulation conveying chains, a dust removing chamber, a leveling chamber, a baking oven, as well as a manipulator and a spraying room that are used by the first and second circulation conveying chains together; the circulation conveying chains are arranged vertically; the workpiece holder enters the dust removing chamber, the spraying chamber, the leveling room and the baking oven in the conveying direction sequentially; the manipulator can seize or place the workpiece holder on the circulation conveying chains and the spraying room; the spraying room is provided with a color changing system and at least two spray guns; and the color changing system controls the spray guns to conduct color changing and spraying on the conveyed workpiece in turns. The spraying production line has the advantages that color changing and spraying are quick; the area occupied by equipment is reduced; the equipment utilization rate is increased; and the production efficiency is improved.

Description

technical field [0001] The invention relates to a spraying production line, in particular to a spraying production line capable of rapid color-changing spraying, reducing the space occupied by equipment, improving equipment utilization and increasing production efficiency. Background technique [0002] In industrial production, in order to further protect the product or make the surface of the product smoother and more beautiful, it is generally necessary to spray the surface of the product. The spraying process has been widely used in products in industries such as automobiles, home appliances, plastics and furniture. [0003] Spraying is a coating method in which the spray paint is dispersed into uniform and fine droplets and applied to the surface of the object to be coated by means of pressure through a spray gun. The existing spraying production line generally transports the workpiece to the closed spray booth through the conveyor belt, sprays the paint through the spra...

Problems solved by technology

However, only one spraying production line is used, and the spray paint of one color is replaced after spraying a batch of workpieces. Although mobile phone casings of various colors can be produced, such production efficiency is extremely low and obviously cannot meet the requirements; and in order to improve production efficiency , it is necessary to use multiple spraying production lines, and each spraying production line sprays paints of different colors at the same time; however, due to the relatively large spraying production line, the simultaneous production of multiple spraying production lines will take up a lot of production space, and when a mobile phone shell of a certain color When the demand is not large, the production will be stopped, so that the utilization rate of the equipment at that time is not high, thereby increasing the production cost
