Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of cyclic ink supply device for ink-jet printer of the present embodiment, comprises shower nozzle 1, print cartridge 11, peristaltic pump 9, ink supply bottle 2.Print cartridge 11 is divided into mutually isolated ink feed chamber and chamber out of ink, and the outlet of shower nozzle 1 connects the reflux inlet in ink feed chamber, and the entrance of shower nozzle 1 connects the bypass outlet in chamber out of ink.Air inlet is provided with above ink bottle 2, ink output channel through stretching into ink connects the ink feed chamber of print cartridge 11 and chamber out of ink, ink output channel is provided with current divider 12, there are two output channels current divider 12 lower end, and two output channels connect the ink feed chamber of print cartridge 11 and chamber out of ink respectively.The negative pressure end of peristaltic pump 9 is connected with ink feed chamber, and positive pressure side is connected with chamber out of ink.When ink is consumed by shower nozzle 1, the quantity of ink being back to print cartridge 11 reduces, and in ink feed chamber, negative pressure increases, and the ink in ink supply bottle 2 can be inhaled into ink feed chamber, adds major cycle.Because ink supply bottle 2 and print cartridge 11 with the addition of part flow arrangement 12, ink supply bottle 2 and ink feed chamber, chamber out of ink are coupled together, during work, ink constantly flows to ink feed chamber from the chamber out of ink of print cartridge 11 by current divider 12, the chamber out of ink of print cartridge 11 is flowed back to again by peristaltic pump 9, current divider 12, print cartridge 11, peristaltic pump 9 is made to define a little ink circulation, ink feed chamber and cavity pressure out of ink are balanced, and avoid ink backflow that imbalance of pressure causes or shower nozzle drips ink, ensure that the stable of ink major cycle.Liquid level sensor 3 is installed in ink supply bottle 2 outside, monitors the ink level of ink supply bottle 2, and passes through the height of the motor 4 adjustment ink supply in real time bottle 2 controlling ink supply bottle 2 adjustable height.Due to certain negative pressure must be maintained in shower nozzle 1 to ensure that ink can not flow out, need to utilize the difference in height between the liquid level of ink supply bottle 2 and shower nozzle 1 base plate to produce required negative pressure.The liquid level sensor 3 installed by ink supply bottle 2 side monitors the liquid level in ink supply bottle 2, microcomputer controls motor 4 and is elevated after receiving liquid level sensor signal, the height of real-time adjustment ink supply bottle 2, constant to ensure the difference in height between the liquid level of ink supply bottle 2 ink inside and shower nozzle 1 base plate, liquid level is remained unchanged always, to provide stable negative pressure relative to shower nozzle 1 base plate.Because the natural physical property of negative pressure by liquid produces, even if power-off, this negative pressure also can keep always.Along with ink consumption, ink supply bottle 2 can raise gradually, and after being raised to certain altitude, system can send the alarm of low ink amount.
Current divider 12 inside is provided with screen pack, is that the first order of ink is filtered; The ink connecting positive pressure side and chamber out of ink is provided with filter I 10, cheap filtration core can be adopted, be that the second level of ink is filtered, can cleaning be disassembled, reusable.
In order to observe the ink level confirmed in print cartridge 11 easily, can install transparent liquid level observing pipe 13 in the side of print cartridge 11, stopper is arranged at the top of this liquid level observing pipe 13, for the first time to the air can opened during ink refilling in stopper discharge ink.
In order to can make to enter shower nozzle 1 ink flow rate evenly and avoid the foreign matter impurity in ink to enter shower nozzle 1, the half chamber I and half chamber II that are separated by filter II 8 are all divided in the ink feed chamber of print cartridge 11, chamber out of ink, half chamber II is connected with peristaltic pump 9, the reflux inlet of print cartridge 11 is arranged on the half chamber I in ink feed chamber, and the bypass outlet of print cartridge is arranged on the half chamber I in chamber out of ink.
In order to discharge air unnecessary in ink feed chamber, top, ink feed chamber connects air extractor 7, and air extractor 7 is provided with liquid level sensor II5, by the switch of liquid level sensor II Controlling solenoid valve 6 to take unnecessary air away.Along with the circulation of ink, the gas in ink can be discharged in real time, ensures the pressure stability in ink, prevents shower nozzle 1 ink.This air extractor 7 is controlled by microcomputer, and when ink occurs sealing problem and enters too much air, system can give the alarm.
In order to can the temperature of controlled circulation ink ink inside, for shower nozzle 1 offers the best printing environment, the ink connecting chamber out of ink bypass outlet and shower nozzle 1 entrance can arrange heater 14.
Operation principle of the present utility model: when ink works, under the driving of peristaltic pump 9, ink enters in the half chamber II in chamber out of ink through filter 10, filter 8 again in print cartridge 11 enters half chamber I(cushion chamber), through buffering, the ink stream flow velocity of pulsed becomes steady, and then ink arrives shower nozzle 1 after heater 14 heats.Shower nozzle 1 prints the ink consuming trace, and most of ink is back to the half chamber I in ink feed chamber, enters in the half chamber II in ink feed chamber, and then enter peristaltic pump 9 through filter II8, forms the major cycle of ink.The a small amount of air entered from shower nozzle 1 passes through the ink feed chamber that circulation is brought into print cartridge 11, and gas rises and automatically enters air extractor 7, is then discharged.
