On site cleaning mechanism of high efficiency coating machine

The utility model discloses an on site cleaning mechanism of high efficiency coating machine. A water inlet electromagnetism valve is arranged on the water inlet pipe; a water ball valve is arranged on the water outlet pipe. The tug inside, tug outside and water accumulation plate cleaning devices are arranged side by side on the water outlet pipe between the water outlet ball valve and the spray gun. The three cleaning devices all comprise a water outlet electromagnetism valve, a water pipe and a spray gun. A pipe is connected with the water outfall of the water accumulation plate; a liquid level control switch is arranged in the pipe; the switch is connected with the PLC mini computer of the coating machine. The electromagnetism valve and the cleaning pump are connected with relevant electric relay and PLC mini computer in the strong electricity ark. By programming the PLC mini computer, water level in the water accumulation plate, water inlet and water outlet of the tug inside, tug outside and water accumulation can all be better controlled. The utility model has the advantages of thorough cleaning, being clean and high automation degree, so workers' labor intensity is reduced and coating machine sanitary grade is improved.
