Double-channel paint spray gun and spraying method thereof

Abstract

The invention discloses a double-channel paint spray gun. The spray gun comprises a gun body and a material conveying vehicle; a gun barrel, a buffer chamber and a nozzle are fixedly arranged at the front end of the gun body; the bottom of the gun body is connected with a first handle and a first double joint; the upper part of the gun body is connected with a switch; a first material barrel, a second material barrel and a motor are fixedly arranged on the upper surface of the material conveying vehicle; the output end of the motor is connected with a material suction cavity; the upper portionof the material suction cavity is connected with a first material barrel and a second material barrel through a third double-joint; a second double-joint is fixedly arranged at the bottom of the material suction cavity; and the second double-joint is fixedly connected with the first double-joint through a hose. The invention further discloses a spraying method of the paint spray gun. Through synchronous improvement of the spray gun structure and the spraying method, the same spray gun is used for spraying two kinds of paint with different components or colors, epoxy transparent paint and colored paint are sprayed through the multiple sets of double connectors respectively, the paint or the paint spraying gun does not need to be replaced in the process, and the working efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of paint spraying, and more specifically relates to a double-channel paint spray gun and a spraying method thereof. Background technique [0002] Spraying is a coating method in which spray guns or disc atomizers are dispersed into uniform and fine droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derived methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. The spraying operation has high production efficiency and is suitable for manual operation and industrial automation production. It is widely used in hardware, plastics, furniture, military industry, ships and other fields. It is the most commonly used coating method today; spraying operations require...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing spraying technology cannot achieve rapid paint replacement, or the entire set of equipment needs to be replaced when the paint is replaced, which will cause more equipment to be maintained during painting, which will cause huge damage to production. consumption, and the existing spray guns carry paint cans on the gun body, but this is only suitable for spraying small devices, which is very inconvenient for large devices and requires frequent addition of paint, which will reduce work efficiency. And it is inconvenient to move the equipment when in use, and it is necessary to turn over the painting device, which is very troublesome and inconvenient to operate, and the paint spray gun is not provided with a buffer device, so that the paint sprayed by the paint spray gun will be affected by the flow rate, making the painting effect Not good, causes uneven paint surface
