Description
Technical field
The present invention relates to a kind of ink jet numbering machine, particularly relate to a kind of number-jetting machine persistent back pressure ink-supplying device that is applied on the ink jet numbering machine.
Background technology
Ink jet numbering machine ink supply mode in the prior art generally is divided into two kinds of forms: a kind of is the ink supply of pure source of the gas formula, and another kind is the ink supply of pure pump conveying-type.The gas China ink road of pure source of the gas formula ink supply needs external big air compressor, safety valve, the air inlet magnetic valve, the air inlet pressure-reducing valve, big air filter, refrigerator, oil water separator, little air filter, pressure-reducing valve, pressure buffer jar or the like is comparatively complicated, the shared volume and weight of above-mentioned gas circuit is all bigger, there is gas to flow out from vacuum generator and pressure-reducing valve always, so air consumption is big and the consumptive material consumption is big, air consumption is big, ink is subject to gaseous contamination, and the China ink of pure pump conveying-type ink supply pressure belongs to hydraulic pressure, because pulsation is big during the magnetic drive pump running, so China ink is pressed unstable, ink viscosity is difficult to control, often because the ink dot shakiness that causes out of control of ink viscosity, and influence coding quality and coding effect, its moving component is worked easy to wear for a long time under higher load condition, service life and stability are all poor, and cost is also very high.
Summary of the invention
The purpose of this invention is to provide a kind of number-jetting machine persistent back pressure ink-supplying device, pass through the technical program, not only can simplify gas China ink road greatly, reduce cost, and can under small tolerance, carry out stable work, and stopped inkiness, reduced the load of each moving component greatly, the viscosity of China ink is well controlled, gas China ink road good stability, thus remedy the deficiencies in the prior art.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of number-jetting machine persistent back pressure ink-supplying device, it comprises quantitative constant air pressure source, the ink supply tube, pump, the level pressure check valve, spray chamber, recover, the China ink bottle, pump China ink magnetic valve, the ink supply magnetic valve, cross valve and control circuit, the top of described ink supply tube links to each other with the air cushioning jar, the air cushioning jar links to each other with pressure source, ink supply tube below is provided with ink outlet port and ink entrance, described ink outlet port is connected to spray chamber through the ink supply magnetic valve, described China ink bottle is through cross valve, pump, first control end of pump China ink magnetic valve is divided into two-way later on, wherein one the tunnel links to each other with ink entrance on the ink supply tube through the level pressure check valve, wherein other one the tunnel directly is connected with the China ink bottle, and the A mouth communicated with the P mouth when first control end of described pump China ink magnetic valve was the energising of pump China ink magnetic valve.
When second control end of described pump China ink magnetic valve is the outage of pump China ink magnetic valve the A mouth with directly link to each other after normal opening communicates with the China ink bottle.
Described black recover is that the black recovery holes on the shower nozzle is connected with the filter of recovery China ink, through reclaiming the China ink filter, is connected with the black magnetic valve of pump by cross valve, pump.
Described quantitative constant air pressure source is to be made of micro air pump, magnetic valve, pressure switch, pressure-reducing valve, pressure buffer jar.
When ink jet numbering machine is started shooting, the micro air pump starting, the ink supply tube is under the effect in quantitative constant air pressure source, quantitative constant air pressure source quits work after maintaining certain air pressure in the ink supply tube, this moment the ink supply tube under this pressure to the shower nozzle ink delivery, carry out coding work, when ink drops to the liquid level test point in the ink supply tube, the ink supply tube is given control circuit with signal feedback, control circuit is given pump China ink magnetic valve power on signal, and first control end is opened, the ink that the pump China ink is received from China ink bottle and recover, squeeze into the ink supply tube through one tunnel level pressure check valve wherein, simultaneously the redundance ink is sent back in the China ink bottle through level pressure check valve lower end passage; When ink rises to the liquid level test point in the ink supply tube, the outage of pump China ink magnetic valve, second control end is opened and is stopped to ink supply tube ink distribution, and pump is squeezed into ink from the A mouth of pump China ink magnetic valve, and the O mouth is returned in the China ink bottle; When ink level drops to down liquid level once more, control circuit has calculated the viscosity of ink by the time of flowing out between the upper and lower liquid level test point of ink supply tube fixing quantity of ink and flowing out, the time of flowing out is long more, illustrate that viscosity is high more, the time of flowing out is short more, illustrate that viscosity is rare more, this moment with time of outflow just ink viscosity feed back in the control circuit, if ink viscosity is higher, just in cross valve, adds diluent and come the ink viscosity in the ink bottle is adjusted.
The number-jetting machine persistent back pressure ink-supplying device good effect that the present invention relates to is: owing to adopt present design, more simple and reliable for structure than traditional pure source of the gas formula ink jet numbering machine ink feeding system, overcome that volume is big, weight is big, air consumption is big, the consumptive material consumption is big, source of the gas is to the pollution problem of ink; Cooperate the automatic control of control circuit realization to the ink jet numbering machine ink, viscosity is higher, adds diluent in ink bottle, and viscosity is rare partially, stop in ink bottle, to add diluent, finish automatic control viscosity, make ink jet numbering machine work smooth more, owing to use parts few, so fault rate is low, cost is low, the complete machine fault rate is low, so the durability height, performance is more stable; Than pure pump conveying-type ink feeding system China ink press more stable, ink viscosity is easy to control, long service life, good stability, cost are low.
