Hot water injection: when on contact screen, selecting " based on water ", only implement this flushing.Utilize supply pump upwards to pull water to chamber from the water memory, bottom the open valve irrigation chamber, all current advance groove then, return pump towing material it is delivered to the waste material device.

Water is discharged: the supply pump drain valve is opened, and stops to supply with water to chamber and discharge the surplus material of system.Only implement this pattern when selection is based coating with water when handling beginning.

Recirculation is cleaned: use and select to obtain this clean cycle with water as based coating or with UV coating.Pass through supply pump, it upwards promotes the wash cycles material from the recirculation memory, utilization is closed the chamber dump valve it is supplied to chamber with filled chamber, and bottom the open valve irrigation chamber, all these coating flow to groove and turn back to the recirculation memory by returning pump then.Water will pollute the UV material for the cleaning and the difference between the UV cleaning on basis are that the UV clean cycle only uses the recirculation memory to supply with cleaning material as any fresh water.

Recirculation is discharged: open the supply pump draining valve and stop to supply with cleaning material and allow surplus material to discharge back and enter the recirculation memory again.

The hot water injection 2: utilize and close the chamber dump valve earlier then with its unlatching, this step is contained the liquid device from hot water supply and is upwards promoted water to chamber.Only can obtain this pattern when selection is based coating with water when handling beginning.

Hot water discharges 2: open the supply pump draining valve, stop water and flow to chamber, and the residue of the system of discharge is to the waste material device.

Chamber unloading: at the last chamber of unloading automatically of cleaning treatment.

Can obviously notice, can be from any residue cleaning liquid of System Cleaning when bringing into operation continuous coating procedure by introducing new coating material.The coating cleaning step uses new coating material to remove any residue cleaning liquid from line and valve, and this material all arrives the waste material device.Afterwards, coating filling and operation phase are avoided any cleaning liquid incompatible with solvent.

With reference to Fig. 1,2 and 7, the line of return 133,134 is affixed to the discharge 61 that returns end of the chamber 24 of scraping cutter device 21.As shown in Figure 1, 2, when system's maintenance engages with traveling roller, because the connection of the cavity bottom line of return 133 recycles coating material in the systemic circulation process, provide the smooth liquid chamber of flowing through as it, the connection of line 133,134 can make liquid discharge from chamber 24.On the other hand, rotate to break away from traveling roller 22 and when traveling roller 22 left, the connection of line 134 was minimum, is used for breaking away from the discharge chamber is set around pivot tube 27 when scraping cutter device 21.In any case, the liquid of at first discharging from chamber flows to groove 70 in atmospheric pressure.
