Ink viscosity self-adaptive ink-jet printing machine and self-adaptive method thereof

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.

Description

technical field [0001] The invention relates to a code-jet printer, in particular to a code-jet printer with self-adaptive ink viscosity and an self-adapting method thereof. Background technique [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...
