It two is cleaning fluid loops: the cleaning fluid bottle is connected to each shower nozzle 7 with cleaning fluid through pipeline through fluid discharge pump and cleaning fluid filter; Between cleaning fluid filter and shower nozzle 9, join by pipeline and the valve body 7 that cleans in main valve 8 and the above-mentioned pipeline of all kinds respectively.Make a road of this cleaning main valve 8 can connect the air source, another road can connect the cleaning fluid bottle.
It three is air loops: promptly air cleaner is injected into clean air in the safety flack 6 through air pump 16 and pressure-reducing valve, and described safety flack 6 is a seal, also is provided with three or more air outlet slit A on its lid; Except that the valve body 7 that between safety flack 6 and shower nozzle of all kinds, is provided with in above-mentioned cleaning main valve 8 and the pipeline of all kinds, also can between pressure-reducing valve and safety flack, also be provided with a triple valve 15.A road of this triple valve communicates with atmosphere, and another Lu Yujing air pump 16 compressions also communicate through the post-decompression air of pressure-reducing valve.Between safety flack and each ink supply bottle 5, also respectively there is a pipeline to be connected.
When the ink supply bottle 5 of certain look lacked China ink, the work of corresponding liquid flow pump after the filtration of ink through the ink filter device in the main China ink bottle of this look, was transported in this look ink supply bottle 5.When printer was normally printed, the road pipeline that triple-valve body 7 communicates with ink supply bottle 5 was opened, this road pipeline closure that communicates with air or cleaning fluid; In print procedure, the ink normal supply shower nozzle in the ink supply bottle is in air loop, the pipeline that valve body communicates with atmosphere is opened, atmosphere directly supplies in the safety flack 6, again by in safety flack 6 and the ink supply bottle 5 direct pipe passage ink supply bottles 5, to guarantee that the pressure in the ink supply bottle is atmospheric pressure.
When cleaning shower nozzle, the road pipeline that triple-valve body communicates with ink still remains on open mode, and the pipeline closure that the triple valve in the air loop communicates with atmosphere, the pipeline that communicates with pressure-reducing valve is opened, air supplies in the safety flack 6 through the air pump compression and after the pressure-reducing valve decompression, the pipeline that communicates with ink supply bottle 5 by safety flack 6 leads in the ink supply bottle 5 again, after ink in the ink supply bottle is under pressure, by pipeline with ink transport to shower nozzle, thereby the impurity that will be blocked in the spray orifice is taken out of, has cleaned shower nozzle thus.At 7 adjacent of valve bodies of described each shower nozzle 9 and each shower nozzle an emergent pipeline 10 (for example triple valve) is set also; In the occasion of some urgent need, mode such as can adopt manually directly to inject cleaning fluid etc. at this, be used for cleaning and the maintenance operation.
When printer will quit work and when needing the maintenance shower nozzle, can convert shower nozzle 9 to the ink of this section pipeline of triple-valve body 7 to cleaning fluid.During operation, earlier the ink in this section pipeline is discharged.At this moment, road pipeline 12 closures that valve body 7 communicates with ink, this road pipeline 11 that communicates with air or cleaning fluid is opened.The pipeline that cleaning main valve 8 in the cleaning fluid loop communicates with air is opened, the pipeline closure that communicates with cleaning fluid.The pipeline closure that valve body 7 communicates with atmosphere in the air loop, the pipeline that communicates with pressure-reducing valve is opened, air supplies in the safety flack 6 through air pump 16 compression and after the pressure-reducing valve decompression, air in the safety flack 6 is through cleaning main valve 8, be transported to valve body 7 then, will discharge at shower nozzle 9 to the ink in this section pipeline between the triple-valve body 7.
After ink arranged, again cleaning fluid is transported to shower nozzle to this section pipeline between the valve body 7.Because the damping of cleaning solution (or ink) is far longer than the damping that air is carried in pipeline,, realize the operation of replacing cleaning solution (or ink) so can be easy to make each road cleaning solution (or ink) to arrive separately shower nozzle basically simultaneously.During operation, the road pipeline closure that valve body 7 communicates with ink, this road pipeline that communicates with air or cleaning fluid is opened.The pipeline closure that cleaning main valve 8 in the cleaning fluid loop communicates with air, the pipeline that communicates with cleaning fluid is opened.The fluid flow pump work is transported to after the filtration of the cleaning fluid in the cleaning fluid bottle through the cleaning fluid filter and cleans main valve 8, then through valve body 7, and then is transported to each shower nozzle, makes shower nozzle be full of cleaning fluid to this section pipeline between the valve body 7, with the maintenance shower nozzle.
In addition, safety flack 6 is except can providing compressed air and normal atmosphere (An), also have an effect to be: when the liquid level position sensor of control liquid level in the ink supply bottle goes wrong, ink can directly not be discharged to outside the bottle, but be discharged in the safety flack 6 by the pipeline between ink supply bottle and the safety flack 6, so just can not pollute machinery equipment.If sensor is set in safety flack, also capable of automatic alarm or cut off the electricity supply, with the automatic protection of implement device.
