The specific embodiment
Pass through specific embodiment below, and combine accompanying drawing, the technical scheme of the utility model is done further to specifically describe:
Below in conjunction with embodiment the utility model is described.As shown in Figure 1, the utility model comprises that negative pressure generates and the protection part, malleation ink guide part and malleation mediation part.Described negative pressure generates and the protection part comprises: air cleaner 1, negative pressure bleeder valve 2, negative pressure pump 3, check valve 4, negative pressure bottle 5, negative pressure switch 6, protection bottle 7, liquid level sensor 8, positive and negative pressure transfer valve 10, secondary China ink bottle 11 and respective line; Described malleation ink guide part comprises: air cleaner 22, positive pressure pump 21, ink supply mediation transfer valve 20; Manual vent valve 18, main China ink bottle 19, main black bottle liquid level sensor 17; Ink filter device 14, check valve 13, secondary China ink bottle 11; Secondary China ink bottle liquid level sensor 12, shower nozzle ink supply switch valve 9, ink gun 15 and corresponding pipeline thereof; Described malleation mediation part comprises: air cleaner 22, positive pressure pump 21, ink supply mediation transfer valve 20, pressure regulator valve 16, positive and negative pressure transfer valve 10, secondary China ink bottle 11, shower nozzle ink supply switch valve 9, ink gun 15 and respective line thereof.
Negative pressure generates and the protection part is worked in the following manner: its switch inside was connected when the negative pressure in negative pressure switch 6 perceives negative pressure bottle 5 was not enough; 3 runnings of starting negative pressure pump, this moment, check valve 4 was opened automatically, and the air in the negative pressure bottle 5 is taken away; Because negative pressure bottle 5, protection bottle 7 and secondary China ink bottle 11 and interconnective pipeline thereof guarantee that negative pressure system is not connected with air; So negative pressure bottle 5, protection bottle 7 and secondary China ink bottle 11 gas inside pressure begin to descend, when negative pressure reached setting value, negative pressure switch 6 switch inside were broken off; Negative pressure pump 3 quits work; Check valve 4 is also closed thereupon, makes the negative pressure in negative pressure bottle 5, protection bottle 7 and the secondary China ink bottle 11 remain on setting value, if need remove the negative pressure in negative pressure bottle 5, protection bottle 7 and the secondary China ink bottle 11 for a certain reason; Only need open negative pressure bleeder valve 2, let air get into negative pressure bottle 5, protection bottle 7 and the secondary China ink bottle 11 and get final product from air cleaner 1 and negative pressure bleeder valve 2.
Owing to certain unexpected reason, the ink in the secondary China ink bottle 11 is inhaled in the protection bottle 7, if there are not two liquid level sensors 8, ink will constantly be inhaled into so; Be discharged into the outside of ink feeding system (equipment promptly forms images) at last through negative pressure pump 3, not only cause the waste of ink, pollute working environment; Also can damage negative pressure pump 3,, in negative pressure system, set up 7 and two liquid level sensors 8 of protection bottle especially for fear of this state occurring; Liquid level sensor 8 can detect the entering of ink, at this moment cuts off the power supply of negative pressure pump 3 rapidly, stops the operation of negative pressure pump 3; And send warning through the control system, avoid fault to enlarge, protection negative pressure pump 3.It is because the probability of protection bottle 7 unexpected suction inks is lower that two liquid level sensors 8 are set; Liquid level sensor 8 in the bottle is in off position for a long time; And it is whether malfunctioning relatively difficult through the oneself of control system detecting sensor 8; Because the price of liquid level sensor is very low,, can improve the reliability of negative pressure system greatly so in protection bottle 7, two liquid level sensors 8 are set simultaneously.
The course of work of malleation ink guide part is following: shower nozzle ink supply valve 9 is normally closed solenoid valves, sets up the negative pressure of negative pressure system after the device power earlier, behind negative regulation, opens shower nozzle ink supply valve 9.During ink level reduction in ink gun 15 ink consumption or other reason make secondary China ink bottle 11; Liquid level sensors 12 in the secondary China ink bottle 11 can detect the deficiency of ink, and at this moment, the control system connects the pipeline that is connected between positive pressure pumps 21 and the main China ink bottles 19 by ink supply mediation transfer valve 20; Start positive pressure pump 21 then; Airtight main China ink bottle 19 pressure inside are raise, overcome the resistance of difference in height and check valve 13 between main China ink bottle 19 and secondary China ink bottle 11 positions when pressure after, ink begins to get into secondary China ink bottle 11; Secondary China ink bottle 11 inner ink levels are raise; When secondary China ink bottle 11 inner liquid levels reached desired location, liquid level sensor 12 perceived this state, and the control system stops the operation of positive pressure pump 21; And cut off the pipeline that is connected between positive pressure pumps 21 and the main China ink bottle 19 by ink supply mediation transfer valve 20, stop secondary China ink bottle 11 ink supply.Air cleaner 22 is used for filtering the air that gets into positive pressure pump 21, with protection positive pressure pump 21, and keeps the cleaning of inks in the main China ink bottle 19; Ink filter device 14 is used for filtering the ink that gets into secondary China ink bottle 11 from main China ink bottle 19, with the protection ink gun; The ink uniaxially that check valve is used for controlling in the main China ink bottle 11 flows into secondary China ink bottle 11, stops ink to reflux.When in the main China ink bottle 19 during ink cartridge low; Main China ink bottle liquid level sensor 17 these states of meeting perception, the control system can give a warning, and at this moment needs manually to give main black bottle 19 to add ink; Because main China ink bottle 19 is airtight containers; When adding ink for secondary China ink bottle 11, in main China ink bottle 19, can leave certain high pressure,, set up manual vent valve 18 for the ease of opening the bottle cap of main China ink bottle 19.Before main China ink bottle 19 adds ink, open manual vent valve 18 earlier, will lead China ink bottle 19 and connect with atmosphere; Discharge its pressure inside, treat after main China ink bottle 19 has added ink, to tighten the lid of main China ink bottle 19; Close manual vent valve 18 again, make main China ink bottle 19 recover air-tight state.
Malleation mediation part is worked in the following manner: bad when the duty of finding ink gun 15, when the spray orifice obstruction takes place, need dredge ink gun 15.During mediation; The control system is communicated with secondary China ink bottle 11 and positive pressure pump 21 through positive and negative pressure transfer valve 10 and ink supply mediation transfer valve 20, and starting positive pressure pump 21 rises secondary China ink bottle 11 pressure inside; Because check valve 13 has cut off ink and has been back to main China ink bottle 19 through the ink supply pipeline; Ink in the secondary China ink bottle 11 can only outwards flow out through ink gun 15, washes away the ink gun 15 of obstruction, reaches the purpose that spray orifice is stopped up in mediation.Pressure regulator valve 16 is used for controlling the size of the malleation that is applied to secondary China ink bottle 11 inside, and protection ink gun 15 exempts from damage.The air mass flow of pressure regulator valve 16 must be less than the flow of positive pressure pump 21, otherwise can't realize the purpose of mediation ink gun 15 in the secondary China ink bottle 11 inner malleations that produce.After mediation finishes; At first stop the running of positive pressure pump 21; At this moment malleation disappears, and secondary China ink bottle 11 inner remaining malleations discharge through pressure regulator valve 16, makes secondary China ink bottle 11 pressure inside consistent with atmosphere; Cut off being connected of secondary China ink bottle 11 and malleation pipeline through positive and negative pressure transfer valve 10 then, make secondary China ink bottles 11 revert to negative pressure system.
More when the ink gun number of imaging equipment, or the number of colours of required ink more all need expand embodiment shown in Figure 1, and Fig. 2 and Fig. 3 are two kinds and expand embodiment.
The embodiment of Fig. 2 generates the negative pressure among the embodiment of Fig. 1 and protection air cleaner 1 partly, negative pressure bleeder valve 2, negative pressure pump 3; Check valve 4; Negative pressure bottle 5, negative pressure switch 6, protection bottle 7; Liquid level sensor 8 and respective line simply repeat malleation continuous ink feeding and malleation mediation part then as shared.
