Problems solved by technology

[0002] In the prior art, for inkjet printers, in order to obtain a more stable inkjet working state, a stable and constant pressure pressure source is set in the ink supply system to maintain the breakpoint and printing stability of the inkjet printer. The present invention In 2004, he disclosed the technical scheme of a self-contained air source inkjet printer with patent No. 200420066957.8. This kind of inkjet printer needs to use a relatively stable air source as the power source for ink supply and cleaning, so it needs a complete set of The air source equipment, air source processing device and voltage stabilizing device, although the components required by these equipment and devices are small, but due to the large number of components, the failure points of the inkjet printer are increased, the working stability is poor, and the failure rate is high

Embodiment Construction

[0013] The present invention and invention are further described below in conjunction with accompanying drawing.

[0014] In the inkjet inkjet printer with ink viscosity self-adaption and its self-adaptive method involved in the present invention, the quantitative pump 1 in the power source distributes the ink to the nozzle 8 and the vacuum generator 3 respectively under the action of constant flow, and enters into the vacuum generator The ink of the device 3 flows back into the ink tank 4 through the damping hole, and at the same time, the vacuum generator 3 generates negative pressure to recycle the ink that does not participate in the printing information in the nozzle 8 to the ink tank 4. When the viscosity of the ink increases, the ink flowing through the damping hole The backflow slows down, the ink supply pressure at the outlet of the quantitative pump 1 and the nozzle 8 increases, and the return flow through the damping hole accelerates when the viscosity of the ink dec...

Abstract

The invention relates to an ink viscosity self-adaptive ink-jet printing machine and a self-adaptive method of the ink viscosity self-adaptive ink-jet printing machine. Pressure is changed through ink viscosity so that self-adaption can be achieved. The ink viscosity self-adaptive ink-jet printing machine comprises a power source and an ink supplying device, wherein the power source is composed of a constant displacement pump, a pump filter, a vacuum generator and an ink box, the ink supplying device is composed of a main ink filter, an ink supplying electromagnetic valve, an end ink filter and a sprayer, an outlet of the constant displacement pump comprises two paths, one path is sequentially connected with the main ink filter, the ink supplying electromagnetic valve, the end ink filter and the sprayer through connection pipelines, the other path is connected with the high-pressure end of the vacuum generator through a connection pipeline by means of the pump filter, and the damping end of the vacuum generator is connected with the ink box through a connection pipeline. By the technical scheme, the prior art is improved subversively, ink viscosity and pressure are automatically regulated through the vacuum generator, and therefore breaking points on the sprayer are guaranteed and stable work of the printer is effectively achieved; the size and the number of fault points of equipment are greatly reduced, and the fault rate of the equipment is decreased in a multiplied mode.
