Description

Technical Field

[0001] The utility model belongs to the technical field of low-pressure spray guns, and in particular relates to a low-pressure spray gun used for spraying and coloring cowhide sofa leather. Background Art

[0002] Low-pressure spraying refers to spraying the spray liquid onto the surface through low-pressure spraying equipment. The uniqueness of low-pressure spraying is that the pressure of the spray liquid is lower than that of high-pressure spraying, but during use, the spray liquid can adhere to the surface better. Low-pressure spraying is suitable for low-viscosity and low-solid content coatings. At present, low-pressure spraying is used when spraying and coloring cowhide sofa leather. Low-pressure spraying mainly uses low-pressure spray guns.

[0003] However, the existing handheld low-pressure spray gun is sprayed by the operator by picking up and aiming at the sofa leather. Because the sofa leather is sometimes not laid flat enough, the paint sprayed from the spray nozzle is not evenly sprayed when passing through the partially bent sofa leather. In addition, the spraying operation of holding the gun body for a long time is labor-intensive, and unstable holding will cause the spraying direction of the gun head to change and affect the spraying quality.

[0004] Therefore, a low-pressure spray gun for spraying and coloring cowhide sofa leather is needed to solve the problems in the prior art that the paint sprayed from the spray nozzle is not uniform when passing through a partially bent sofa leather, and the labor intensity is high and the spray direction control is unstable when the spraying operation is performed by holding the gun body.
