[0002] When testing the performance of coatings, the experimenters need to prepare a large number of uniform coating test panels. The traditional manual spraying method depends largely on the experience and skills of the operator, so it is often difficult to ensure the stability and consistency of the quality of the coating. In order to solve this problem, a laboratory-specific pneumatic spray gun came into being. This equipment can effectively control the speed, angle and distance of the spraying, thereby ensuring the uniformity and consistency of the coating. In addition, compared with the vertical automatic spray gun, the horizontal automatic spray gun is more suitable for spraying special-shaped workpieces and adopts a double spray gun (semi-automatic) design.

[0003] However, the existing technology still has the following shortcomings: when the spray gun of the reciprocating sprayer is too close or too far from the workpiece, coating defects such as uneven coating and pitting may occur, or the coating spraying adhesion is low and the coating is wasted. Therefore, the spraying distance of the reciprocating sprayer needs to be adjusted very accurately during use. For this purpose, the present application provides a two-way pneumatic reciprocating sprayer. Utility Model Content
