Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying, in particular to a pearl white paint spraying device. Background Art

[0002] The prior art announcement number is CN111589676B, which discloses a method for spraying automobiles using a color paint sharing system, and the steps are: electrophoretic treatment of the car body → spraying white intermediate paint → spraying white base paint on the first color paint station → selecting a process according to the design color of the car body on the second color paint station: when the design color is pearl white, the robot automatically sprays pearlescent paint, and when the design color is plain white, the robot is empty → pre-drying the color paint → spraying varnish; the spray film thickness of the white intermediate paint is 18-22μm; the spray film thickness of the white base paint on the first color paint station is 10-18μm; the spray film thickness of the pearlescent paint of the pearl white model on the second color paint station is 5-10μm. The automobile spraying method of the present invention reduces the number of color paint main pipelines occupied by one in the painting workshop, and at the same time allows the plain white model and the pearl white model to be produced on the same line without competing for color paint resources.

[0003] In view of the current four-coat spraying process of pearl white color in the automobile industry: spraying primer - spraying white base of color paint - spraying pearlescent powder of color paint - spraying clear varnish, for the three-coat production line, it is necessary to add a color paint spraying robot to the coating line to realize production. The robot layout of many plastic coating workshops is not suitable for four-coat products (the production line is designed according to the three-coat process, one cup and one gun for color paint, and one cup and two guns for the four-coat process), so it is impossible to go offline in one go, and it takes two turns to complete the normal offline, which has a huge impact on energy consumption, labor, and production capacity. Based on this, the existing spraying device has the problem of inconvenience in installing multiple spray guns, which needs further improvement. Utility Model Content
