Anti-blocking spraying machine with gun distance adjusting function

Abstract

The invention relates to an anti-blocking spraying machine with a gun distance adjusting function. The anti-blocking spraying machine with a gun distance adjusting function comprises a main body, a second pipeline, a first pipeline, a filter screen, a third pipeline, a spraying mechanism and a cleaning mechanism, wherein the cleaning mechanism comprises a bracket, a first driving assembly, a firstbearing, a second bearing, two supporting rods, two cleaning brushes and at least two transmission rods; the spraying mechanism comprises a second conveying pipe, a first conveying pipe, a nozzle, asecond driving assembly, a fixing block, a distance sensor and a sliding rod; and the first driving assembly comprises a first motor, a first gear and a second gear. According to the anti-blocking spraying machine with the gun distance adjusting function, the filter screen can be cleaned through the cleaning mechanism, so that the blockage probability of the filter screen is reduced, and the spraying effect of the spraying machine is improved; the distance between the nozzle and a to-be-coated surface can be automatically adjusted through the spraying mechanism, so that the spraying pressure is kept stable, and the spraying effect of the spraying machine is further improved.

Description

technical field [0001] The invention relates to the field of painting equipment, in particular to an anti-blocking spraying machine with a gun distance adjustment function. Background technique [0002] The spraying machine is a special coating equipment that adopts spraying technology. The principle is to control the air flow to instantly push the air distribution reversing device to change direction, so that the piston of the air motor makes a stable and continuous reciprocating motion. The inhaled paint is pressurized, and the paint is delivered to the spray gun of the sprayer through the high-pressure hose, and the paint is atomized by the spray gun and released to the surface of the object to be coated. The spraying machine is mainly composed of a feeding device, a spray gun, and an atomization source. Suitable for leather handbags, gift packaging, furniture, footwear, automobile manufacturing and other industries. [0003] The distance between the nozzle of the spray...

AI Technical Summary

Problems solved by technology

[0003] The distance between the nozzle of the spray gun and the surface of the object to be coated is called the gun distance. In the process of using the spraying machine in the prior art, if the gun distance is too small, the spraying pressure will be too high, and the phenomenon of uneven coating will easily occur. The pressure loss is large, and the paint is easy to lose, causing the coating film to fail to meet the thickness requirements. Not only that, the filter screen of the feeding pipe of the spraying machine in the prior art is easily blocked by impurities in the paint, resulting in insufficient material supply to the spraying machine, reducing the Spraying effect of spraying machine
