The ink is sucked into a pneumatic three-way valve I5 from an ink barrel 11, enters a pneumatic four-way valve 15, enters a diaphragm pump II 2, enters the pneumatic four-way valve 15 again, and then enters an ink cavity 9 through a port P. The ink flows out from the ink cavity 9O, enters the ink disk 8, enters the diaphragm pump I1, passes through the BC port of the pneumatic three-way valve III 7 and finally flows into the ink barrel 11. After printing is finished, ink is discharged, the working state is switched by only the pneumatic four-way valve 15 from D-E to F-G to D-F to E-G, and the ink in the ink cavity 9 is pumped back into the ink barrel 11 by the diaphragm pump I1 and the diaphragm pump II 2 through the O port and the P port respectively. The whole process is shown in fig. 2.
In the first purge, as shown in fig. 3, the pneumatic valve ii is opened in the state where ink discharge is completed, the JH port of the pneumatic three-way valve i 5 is connected, the pneumatic four-way valve 15 is switched from D-F and E-G to D-E and F-G, the ML port of the pneumatic three-way valve ii 6 is connected, and the AB port of the pneumatic three-way valve iii 7 is connected. The solvent in the solvent barrel II 13 enters the pneumatic three-way valve I5 through the pneumatic valve II 4, then enters the pneumatic four-way valve 15, enters the pneumatic four-way valve 15 again through the diaphragm pump II 2, and finally enters the ink cavity 9. After the ink cavity 9 is preliminarily cleaned, the solvent enters the ink disc 8, is pumped into the pneumatic three-way valve III 5 by the diaphragm pump I1, and then returns to the solvent barrel II 2 through the pneumatic three-way valve II 6. When the solvent is filled in the whole system, the air-operated valve II 4 is only required to be switched off, the air-operated three-way valve II 6 is only required to be switched on, and the NL port is connected. The solvent is circulated throughout the system, and the ink chamber 9 is deeply cleaned.

The cleaned solvent was pumped into the solvent tank I12 by the diaphragm pump I1 and the diaphragm pump II 2, respectively.
In the second cleaning, as shown in FIG. 4, the air-operated valve II 4 is turned off and the air-operated valve I3 is turned on in the state where the first cleaning is completed, and the air-operated four-way valve 15 is switched from D-F and E-G to D-E and F-G. Clean solvent is by diaphragm pump II 2 through pneumatic valve I3, pneumatic three-way valve I5's JH mouth, and pneumatic four way valve 15, diaphragm pump II 2 enter into black chamber 9, are full of back in black chamber 9 when clean solvent, get back to in the ink pan 8, then enter into solvent bucket II 13 by diaphragm pump I1 through pneumatic three-way valve III 7's AB mouth and pneumatic three-way valve II 6's ML mouth. When the solvent is filled in the whole system, the air-operated valve I3 is only required to be switched off, the air-operated three-way valve II 6 is only required to be switched on, and the NL port is connected. The solvent is circulated throughout the system, and the ink chamber 9 is deeply cleaned. After the circulation is carried out for a certain time, the pneumatic valve II 4 is opened, the pneumatic three-way valve II 6 is switched, the ML port is switched on, the pneumatic four-way valve 15 is switched from D-E and F-G to D-F and E-G, and then the solvent can be discharged.
