A Spray Gun for Spraying with Convenient Angle Adjustment

Abstract

The invention discloses a spray gun for spraying with convenient angle adjustment. The invention is provided with an auxiliary spraying mechanism in the front direction and / or rear direction of the nozzle. When the nozzle is feeding and spraying, the auxiliary spraying mechanism in the front direction Part of the spray medium can be sprayed on the surface of the workpiece, and a layer of sprayed material can be applied to the surface of the workpiece in advance. This layer of sprayed material is generally thin and can form a good layer of film. When the nozzle is used for vertical high-pressure spraying, it can be used The high pressure attaches the film formed by the sprayed material previously coated on the surface of the workpiece to the surface of the workpiece under high pressure to improve the adhesion. The auxiliary spraying mechanism on the rear side can attach part of the spraying medium to the surface that has been sprayed, improving the thickness of the spray and the film formation. In addition, the auxiliary spraying roller of the auxiliary spraying mechanism can also absorb part of the spraying medium that is reflected when the nozzle is sprayed on the surface of the workpiece, and then sprayed on the surface of the workpiece again.

Description

technical field [0001] The invention relates to the technical field of spray guns, in particular to a spray gun for spraying with convenient angle adjustment. Background technique [0002] For most products, in order to be beautiful and protect the surface, it is generally necessary to set up spray head equipment to spray the product. At present, the spray gun is the most widely used spray equipment, and the application range of the spray gun is very wide. The requirements for the spray gun itself will gradually become higher and higher. However, the existing spray guns for spraying not only need to adjust the angle better, but also have high requirements for the performance of spraying. The current spray guns generally only use high pressure Spraying the spray medium on the surface of the workpiece requires high surface quality.

[0002] For most products, in order to be beautiful and protect the surface, it is generally necessary to set up spray head equipment to spray the product. At present, the spray gun is the most widely used spray equipment, and the application range of the spray gun is very wide. The requirements for the spray gun itself will gradually become higher and higher. However, the existing spray guns for spraying not only need to adjust the angle better, but also have high requirements for the performance of spraying. The current spray guns generally only use high pressure Spray the spray medium on the surface of the workpiece. This method requires high surface quality of the product. It not only requires no oil stains, but also requires a certain roughness on the surface. A surface that is too smooth is not conducive to the adhesion of the spray medium to the surface.

Moreover, the surface quality of spraying is often not high, and it is prone to problems such as excessive impact spraying pressure that causes the spraying medium to spill and cause unevenness.
