Problems solved by technology
[0003] This kind of LMI diaphragm pump often fails to spray the solvent after the machine is shut down for more than 1 hour. If the solvent is not added in time during use, air will enter the solvent pipeline, resulting in the solvent not being sprayed out, resulting in printing. The continuous tin and less tin, and the solvent spraying time is long in the above method, and the solvent pump is easy to be damaged

Embodiment Construction
[0009] Please refer to figure 1 Shown is a schematic diagram of the present invention. The invention provides a spraying system for a printing machine, which is mainly used in the wiping process of a printing machine. The solvent needs to be sprayed onto the wiping paper before wiping. The printing machine spraying system mainly includes an air pump 101, a high-pressure barrel 102, a switch Valve 103, spray pipe 104, time relay 105 and power supply 106.
[0010] Wherein, the air pipe (not shown) that this air pump 101 is provided with stretches in this high-pressure barrel 102, and again, this spray pipe 104 one end stretches in the solvent in this high-pressure barrel 102, and its other end stretches out this high-pressure barrel 102 In this way, the gas from the air pump 101 is passed into the high-pressure barrel 102 to increase the air pressure in the high-pressure barrel 102 to press the solvent in the high-pressure barrel 102 into the spray pipe 104 .

The invention provides a spraying system for a printing machine. The spraying system mainly comprises an air pump, a high-pressure barrel and a spray nozzle, wherein an air pipe of the air pump stretches into the high-pressure barrel; one end of the spray nozzle stretches into a solvent in the high-pressure barrel, and the other end of the spray nozzle stretches out of the high-pressure barrel. The system also comprises a switch valve and a time relay, wherein the switch valve is arranged at one end of the spray nozzle stretching out of the high-pressure barrel; the time relay is connected with a power supply of the printing machine; and the time relay is electrically connected with the switch valve and controls the spraying of the solvent by controlling the opening and closing of the switch valve. The opening and closing of the switch valve is controlled by the time relay so as to control the spraying time of the solvent; and air in the spray nozzle can be quickly exhausted so as to ensure normal spraying and reduce solder bridging, insufficient solder and other adverse conditions.
Description
technical field [0001] The present invention relates to a spraying system, in particular to a system for spraying solvents used in the wiping process of printing presses Background technique [0002] At present, on the MPM printing machine, the steel plate needs to be wiped once every few printed circuit boards are produced. When wiping the steel plate, the solvent needs to be sprayed onto the wiping paper. The existing machine uses an LMI diaphragm pump to pump the solvent. [0003] This kind of LMI diaphragm pump often fails to spray the solvent after the machine is shut down for more than 1 hour. If the solvent is not added in time during use, air will enter the solvent pipeline, resulting in the solvent not being sprayed out, resulting in printing. The continuous tin and less tin, and the above-mentioned method of spraying solvent takes a long time, and the solvent pump is easy to be damaged. Contents of the invention [0004] In view of the above problems, the presen...
