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 is comparatively complicated, volume and weight is all bigger, air consumption is big and the consumptive material consumption is big, ink easily pollutes, and the China ink of pure pump conveying-type ink supply is pressed instability, ink viscosity is difficult to control, often because the out of control of ink viscosity caused the ink dot shakiness, and influences coding quality and coding effect, that its moving component is worked under higher load condition for a long time is easy to wear, 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, ink viscosity 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, spray chamber, the ink recovery road, the China ink bottle, four-way, pump, level pressure check 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 four-way, pump, first control end of pump China ink magnetic valve is divided into two-way later on, wherein one tunnel process level pressure check valve links to each other with ink entrance, and wherein other one tunnel direct and black bottle is connected.
Second control end of described pump China ink magnetic valve directly links to each other with the China ink bottle.
Described ink recovery road is that the black recovery holes on the shower nozzle is connected with filter of recovery China ink and recovery magnetic valve, through reclaiming magnetic valve, is connected with the black magnetic valve of pump by four-way, pump.
Described quantitative constant air pressure source is to be made of micro air pump, air pump solenoid valve, pressure switch, pressure-reducing valve, pressure surge tank.
When ink jet numbering machine start ink supply, micro air pump and pump starting, after maintaining certain air pressure in the ink supply tube, quantitatively the constant air pressure source quits work, this moment the ink supply tube under this pressure to the shower nozzle ink delivery, carry out coding work, when ink drops to liquid level in the ink supply tube, control circuit is given pump China ink magnetic valve signal, first control end is opened, the ink that pump is received from China ink bottle and ink recovery road is squeezed into the ink supply tube through one tunnel level pressure check valve wherein, and in another road sends back to the redundance ink in China ink bottle; When ink rises to liquid level in the ink supply tube, the outage of pump China ink magnetic valve, second control end is opened, and pump is returned ink in the China ink bottle; When ink level dropped to down liquid level, control circuit had calculated the viscosity of ink by flowing out the ink supply tube ink time, and feed back in the control circuit this moment adjusts the ink viscosity in the ink bottle.
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, make ink jet numbering machine work smooth more, fault rate is low, and cost is low, durability is high, and 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.
