Pearl powder paint spraying device as well as spraying method

Abstract

The invention discloses a pearl powder paint spraying device. The pearl powder paint spraying device comprises a compressed gas station and a spraying pressure tank, wherein the compressed gas station is arranged on a coating line; the spraying pressure tank is arranged on the coating line and is connected with the compressed gas station; the spraying pressure tank is connected with a paint and gas pipeline connecting device as well as a circulating pressure pump connected with the compressed gas station; the paint and gas pipeline connecting device is respectively connected with the circulating pressure pump as well as a manual spraying pipeline or spraying robot. According to the pearl powder paint spraying device as well as spraying method, the pearl powder paint spraying is realized through an individual system, and the problem that the quality is lowered caused by no use for a long time cannot be generated; the coating cost is lowered greatly; additionally, pearl powder paint is supplied by an individual system, and the problem of high input cost by central paint conveying and blending is solved.

Description

technical field [0001] The invention relates to the field of vehicle painting, in particular to a pearl powder paint spraying device and a spraying method. Background technique [0002] In the field of vehicle coating, it has become an important research topic to explore the high efficiency and low cost in the field of automotive industry coating; and in terms of reducing the cost of automotive topcoat, many passenger car manufacturers have adopted 100% rotary cup, that is, coating Both the first and second lines of the production line use rotary cups, and use the mixed process of spraying natural paint, metallic paint and pearlescent base paint to achieve the purpose of reducing costs and increasing efficiency. [0003] Pearlescent pigments can obtain pearl luster, rainbow effect and metallic luster, and pearlescent powder paint is gradually applied to vehicle spray paint. However, most automobile manufacturers only use pearlescent powder paint on some single-color models,...

AI Technical Summary

Problems solved by technology

However, most automobile manufacturers only use pearlescent powder paint on some single-color models, and the production volume is small; if the rotary cup is also used on the second line of the painting production line, since the pearlescent powder paint circulates in the circulation system for a long time, it is easy to Cause paint quality problems such as natural sedimentation of the paint, which is easy to cause waste of cost

At the same time, the paint circulation system is generally designed according to the technical requirements of water-based paint, and after putting in pearlescent powder paint; it must adapt to the feasibility of using solvent-based paint and switching to water-based paint, the equipment investment cost is relatively large, and the requirements for different energy use More demanding, far from meeting the production needs of high efficiency and low cost
