Spray gun with electric spray breadth adjusting function for automobile paint spraying and using method thereof

Abstract

The invention relates to the technical field of automobile paint spraying, in particular to a spray gun with an electric spray breadth adjusting function for automobile paint spraying and a using method thereof. The spray gun comprises a spray gun body and a trigger, the outer side of the spray gun body is rotationally connected with the trigger, and the inner side of the right end of the spray gun body is rotationally connected with a breadth adjusting rod; and an automatic adjusting device is arranged on the outer side of the breadth adjusting rod, a protective device is fixedly connected tothe outer side of the left end of the spray gun body, and the automatic adjusting device comprises a fixing frame, a sleeve, a bearing, a first gear ring, a first gear, a micro motor, a protective shell and a rectangular block. According to the spray gun, through the arrangement of the fixing frame, the sleeve, the bearing, the first gear ring,the first gear, the micro motor, the protective shelland the rectangular block, the breadth adjusting rod can be driven to rotate automatically under the action of a first motor and a gear, the breadth adjusting rod does not need to be rotated manually, and therefore workers can use the spray gun conveniently; and the workers can conveniently adjust the spraying breadth at any time in the spraying process.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to a spray gun with electrically adjustable spray width for automobile painting and a using method thereof. Background technique [0002] Spray gun, as the name suggests, "spray" means spraying and painting, "paint" means paint, which means paint, and a paint spray gun is a tool for spraying paint. It is used for surface treatment of products and is a kind of coating equipment. The air atomizes the paint into fine paint droplets, which are sprayed onto the surface of the object to be coated under the drive of the airflow. It is mainly composed of a spray nozzle, a needle valve and a gun body. At the same time, an air pressure device needs to be connected externally, such as a pressure tank, a pressure barrel, and a pump. etc. Compared with the traditional manual painting, the spray gun is more time-sensitive and more beautiful, and the efficiency is 5-10 times higher tha...

Problems solved by technology

[0003] Most of the spray guns currently on the market adjust the spray width of the spray gun manually. Since the spray width needs to be adjusted frequently during the painting process, it is very troublesome for the staff to manually adjust. At the same time, the general spray gun cannot limit the trigger. The fixed position requires the staff to hold the trigger with their hands all the time, which will cause sore fingers of the staff after a long time, which is not convenient for the staff to use, and the general spray gun does not have the effect of shielding and protecting the atomized paint generated during the painting process , it is easy to cause the atomized paint to fall on the hands of the staff. Therefore, in view of the above problems, a spray gun with electrically adjustable spray width and its application method for automobile spray painting are proposed
