Abstract
The invention discloses a spray gun of a powder coating machine. The spray gun comprises a spray pipe and a nozzle connected at the front end of the spray pipe and is characterized in that a feeding port is arranged at the back end of the spray pipe, a valve used for controlling feeding is arranged on the inner side of the feeding port of the spray pipe, a gas inlet pipe is further arranged in the nozzle, and a gas inlet switch is arranged outside the gas inlet pipe. A gas outlet of the gas inlet pipe is arranged in the nozzle, and an outlet of a mixing cavity at the front end of the nozzle is conical. Compared with the prior art, the gas inlet pipe of the spray gun is arranged in the spray pipe, the mode of filling gas on the middle portion and feeding materials on the outer portion is adopted, powder materials on the outer portion can be sufficiently mixed in the mixing cavity under effect of airflow on the middle portion, and accordingly the powder materials are led to be evener.
Description
Technical field
The present invention relates to whitewash field of mechanical technique, specifically is a kind of spray gun that is used for powder coating machine.
Background technology
Powder coating machine is the machinery that whitewashes that is used in the finishing work, powder is sprayed on through spray gun accomplishes the work of whitewashing on the metope.Spray gun generally all has charging aperture and air inlet port, the pressure through gas with spraying of powdery row material on metope.But existing spray gun all is the middle part is feed pipe, and external feed stream is so exist the uneven phenomenon of powder to exist.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that exists to above-mentioned prior art, and provides a kind of powder to mix spray gun.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of powder coating machine spray gun; The nozzle that comprises jet pipe and be connected the jet pipe front end is characterized in that: the rear end of described jet pipe is a charging aperture, is provided with the valve that is used to control charging in the charging aperture inboard of jet pipe; In jet pipe, also be provided with air inlet pipe, be outside equipped with the air inlet switch in air inlet pipe.
The gas outlet of described air inlet pipe is positioned at described nozzle, and the hybrid chamber outlet of spray nozzle front end is taper.
Compared with prior art, air inlet pipe of the present invention is arranged in the jet pipe, adopts the middle part air inlet, the mode of outside charging, and the effect of middle part air-flow is used in hybrid chamber and can mixes more fully in the outside powder, thereby makes powder more even.
