Abstract

The invention discloses a spraying cleaning system which comprises a control switch, a control switching device, a thinner valve, a cleaning device and a pneumatic valve. The control switching device comprises a total time relay circuit, a solvent time relay circuit and an air time relay circuit. The control end of the total time relay circuit is connected with the solvent time relay circuit and the air time relay circuit. The output end of the solvent time relay circuit is connected with a first electromagnetic valve, and the control end of the first electromagnetic valve is connected with a spray gun pipeline of the cleaning device through the pneumatic valve and the thinner valve. The output end of the air time relay circuit is connected with a second electromagnetic valve, and the control end of the second electromagnetic valve is connected with the spray gun pipeline of the cleaning device through the pneumatic valve. According to the spraying cleaning system provided by the embodiment of the invention, the structure in which the time relay circuit and the pneumatic valve are linked is constructed, and air and the cleaning solvent are alternately used for cleaning, so that the consumption of the solvent is greatly reduced, and a good cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of coating cleaning, in particular to a spray cleaning system. Background technique [0002] For the painting process of the vehicle, it is necessary to adopt a series of spraying systems that can provide the paint required for spraying. Since the body has different colors, when the color of the body to be sprayed changes, the spray gun for manual spraying of the interior needs to be re-colored. In the prior art, one paint color corresponds to a set of systems, and before each color change, all the solvent of the previous color in the spray gun needs to be discharged until the pipeline is clean. Such a spraying system will increase the operating cost of the entire system, consume a large amount of solvent, and cause waste of resources. SUMMARY OF THE INVENTION [0003] The invention provides a spray cleaning system to solve the technical problem of huge consumption of solvent resources in the existing spr...
