A spray gun with adjustable spray surface

Abstract

The invention discloses a spray gun capable of adjusting a mist-spray surface. The spray gun comprises a gun body, a gun head outer nozzle, a gun head inner nozzle, a gas needle adjustment device and an oil pot, wherein the gun head outer nozzle comprises an outer nozzle outer spray head, an outer nozzle inner ring, an outer nozzle connection ring and a mist-spray rotary adjustment ring, two gas paths are formed in the outer nozzle outer spray head, a tangential spray port is formed in the tail end of each gas path, the outer nozzle inner ring is of a hollow structure, an inclined stop wall and a positive spray port are installed at the front end of the outer nozzle inner ring, and two communication holes are formed in the tail part of the outer nozzle inner ring; the gas paths on the gun head outer nozzle are connected with the outer nozzle inner ring through the communication holes; the gun head inner nozzle is of a hollow conical structure, an oil path is arranged in the gun head inner nozzle, and an oil outlet port is formed in the front end of the gun head inner nozzle; and the gun body comprises a gun body gas path and a gun body oil path, the gun body gas path is communicated to the outer nozzle inner ring, and the gun body oil path is communicated with the oil path of the gun head inner nozzle. The spray gun disclosed by the invention has the advantages of being wide in application range, convenient to operate, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the field of mechanical spraying, in particular to a spray gun with an adjustable spray surface. Background technique [0002] With the development of modern coating technology, the requirements for spraying effects are also increasing, which promotes the continuous improvement of spraying equipment. As the core component of spraying equipment, the performance of the spray gun determines the protective effect of the coating. Because the traditional spray gun basically adopts an integrated gun body, the structure of the gun head is single, the air flow is large, the design of the atomization spraying mechanism at the end of the spray gun is unreasonable, the atomization is uneven, the spray effect is poor, and the spray area can only pass through the front and rear. Adjust the distance between the spray gun and the spraying surface by moving it. In the actual spraying process, if the spraying distance is too far, it is easy to c...

Problems solved by technology

Because the traditional spray gun basically adopts an integrated gun body, the structure of the gun head is single, the air flow is large, the design of the atomization spraying mechanism at the end of the spray gun is unreasonable, the atomization is uneven, the spray effect is poor, and the spray area can only pass through the front and rear. Adjust the distance between the spray gun and the spraying surface by moving it. In the actual spraying process, if the spraying distance is too far, it is easy to cause insufficient spraying surface; if the spraying gun is too close to the spraying surface, the spraying cross distance is short, and it is easy to cause flying paint and hanging on the wall. It is not only a waste of paint, but also a great pollution to the environment. It is difficult to adapt to the spraying needs of modern production.
