Abstract

The invention relates to the technical field of surface treatment, in particular to a sand-blasting gun, which comprises a nozzle mechanism, a spray gun main body, an air supply mechanism and a sand supply mechanism. The nozzle mechanism comprises a nozzle, a nozzle sleeve and a locking nut, the nozzle is arranged in a cavity of the nozzle sleeve which is connected with a front end portion of the spray gun main body through the locking nut. The air supply mechanism comprises an air nozzle and a protective jacket which is sleeved on the outer wall on the front end portion of the air nozzle, the middle portion of the air nozzle is fixed on the back end portion of the spray gun main body, and the protective jacket and the front end portion of the air nozzle are located at the cavity of the spray gun main body. The sand supply mechanism comprises a sand nozzle and a sand nozzle sleeve, and two ends of the sand nozzle are respectively sleeved on the sand nozzle sleeve and the lower end portion of the spray gun main body. The nozzle sleeve and the locking nut both guarantee that the nozzle and the spray gun main body have a same axle wire, so that sand blasting efficiency of the sand-blasting gun can be improved, and cleaning and processing efficiency are improved accordingly. The protective jacket has good protective effects on the air nozzle, damage to the air nozzle caused by the sand flow is avoided, service life of the air nozzle is prolonged, and service life of the sand-blasting gun is prolonged accordingly.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a sandblasting gun. Background technique [0002] Sandblasting guns are widely used in cleaning processes such as rust removal, descaling, and deburring of workpieces. The so-called sandblasting is the process of using high-pressure or high-speed airflow to mix sand and airflow in the sandblasting device to form a sandblasting jet mixed with sand and air, so that the sand hits the surface of the workpiece at a certain speed to obtain the expected cleaning effect. [0003] The structure of the prior art sandblasting gun generally includes a gun body, a nozzle, an air supply mechanism and a sand supply mechanism. However, due to the unreasonable structural design of the sandblasting gun in the prior art, the sandblasting efficiency is low and the service life of the sandblasting gun is short. Contents of the invention [0004] The purpose of the present invention is t...
