Large-flow high-speed and high-pressure spray gun and spraying method thereof

Abstract

The invention discloses a large-flow high-speed and high-pressure spray gun. The large-flow high-speed and high-pressure spray gun comprises a gun body and a paint box, the top of a gun butt is fixedly connected with the right end of the bottom of a gun barrel, a fixed sleeve is fixedly connected to the left end of the top of the gun barrel, a rotating shaft is rotatably connected to the inner part of the fixed sleeve, a triangle sleeve is fixedly connected to the outer part of the left end of the rotating shaft, three sprayers are fixedly connected to the inner part of the triangle sleeve, and fixed pipes are fixedly connected to the inner parts of the sprayers. The invention further discloses a spraying method of the large-flow high-speed and high-pressure spray gun. The structure and process of the spray gun are synchronously improved, thus the spray gun can be adapted to a variety of liquids, pressure gases and work purposes, the spraying speed is high, the air pressure and ventilatory capacity both are high, and for different working surfaces, a gun head or the whole spray gun does not need to be replaced; and according to the large-flow high-speed and high-pressure spray gun,the air pressure of the spray paint can be increased to 0.6-0.9 Mpa, the ventilatory capacity is increased to 150-200 l / min, the spraying efficiency is 2-3 times higher than the prior art, a coatingis fine, smooth and even, and the application range of the large-flow high-speed and high-pressure spray gun is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of paint spraying guns, in particular to a large-flow, high-speed, high-pressure paint spraying gun and a spraying method thereof. Background technique [0002] Paint spray gun, as the name suggests, "spray" means spraying and painting, "paint" means paint, which means paint, paint spray gun is a tool for spraying paint, used for surface treatment of products, and is a kind of coating equipment. It uses compressed air to atomize 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. Barrels, pumps, etc. Compared with the traditional manual painting, the spray gun is more time-sensitive and more beautiful, and its efficiency is higher than that of brushing, and the coating film is fine, smooth and uniform. [0003] When designing and manufacturing spray guns, var...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a large-flow, high-speed, high-pressure paint spray gun and its spraying method. By synchronously improving the structure and process of the spray gun, the existing paint spray gun cannot be adapted to various liquids, pressure gases and For the purpose of work, and the spraying speed is low, the air pressure and air flow are low. For different working surfaces, the need to replace the gun head or replace the entire spray gun, etc., it can simultaneously increase the spraying air pressure and air flow to the normal 2~ 3 times, the spraying efficiency is 2 to 3 times higher than the existing technology, and the coating film is fine, smooth and uniform
