Problems solved by technology

At present, the traditional spray gun cannot control the injection amount (flow rate) of the paint when the delivery pipeline is transported to the spray gun, resulting in too much or too little pigment injected into the delivery pipeline, thereby reducing the spraying effect of the spray gun

Abstract

The invention relates to a spraying flow control method and a spraying device. The spraying flow control method comprises a spraying gun, an air compression mechanism, a spraying gun air supply mechanism, a pigment conveying mechanism, a central control mechanism and an adjusting mechanism. The spraying flow control method further comprises the following steps of conveying airflow to the spraying gun air supply mechanism and the pigment conveying mechanism through the air compression mechanism; providing jet power for the spraying gun through the spraying gun air supply mechanism; conveying pigment to the spraying gun through the pigment conveying mechanism; monitoring the flow of the pigment conveyed to the spraying gun by the pigment conveying mechanism through the central control mechanism; and adjusting the flow of the pigment conveyed to the spraying gun by the pigment conveying mechanism through the adjusting mechanism. According to the spraying flow control method, the flow of the pigment can be adjusted, and therefore the spraying effect of the spraying gun is guaranteed.

Description

technical field [0001] The invention relates to the technical field of spraying flow control methods, in particular to a spraying flow control method and a spraying device. Background technique [0002] According to the actual usage, the railway wagons will carry out marking and painting operations on the trucks and vehicles. Traditional marking and painting operations are all done manually. For example: the operator uses manpower or an electric trolley to drive to a specific part of the vehicle, and needs to hold a leaky mold and a paint spray gun for marking. At present, the traditional spray gun cannot control the injection amount (flow rate) of the paint when the delivery pipeline is transported to the spray gun, resulting in too much or too little pigment injected into the delivery pipeline, thereby reducing the spraying effect of the spray gun . Contents of the invention [0003] Based on this, it is necessary to provide a spraying flow control method and a sprayin...
