Abstract
The invention relates to an ink supply system of an ink jet printer, which comprises an ink gun, a central print cartridge, ink pumps, an ink valve, an ink supplement apparatus and a waste ink recovery apparatus. According to the invention, two ink pumps are used to control the ink supply to the ink gun by the central print cartridge together; phenomenon like insufficient ink supply to the ink gun is further improved; ink supply rate to the printer is raised; ink return path is formed; the ink in an ink pipe and in the ink gun is discharged to the central print cartridge with air. In this way, the air inside the ink pipe can be removed and the ink won't be wasted. The waste ink retrieving apparatus makes it difficult to pollute the printer; the printing is more environment-protective; multiple sensors are used in the system, making the operation of the printer more intelligent and accurate, thereby reducing extra labor cost and providing accurate execution.
Description
Technical field:
The present invention relates to printer apparatus, particularly relate to a kind of ink feeding system of ink-jet printer.
Background technology:
Ink-jet printer adopts technology to mainly contain two kinds: continuous ink jet technology and random mode ink-jet technology.The ink-jet printer of early stage ink-jet printer and current large format is all adopt continuous ink jet technology, and the popular ink-jet printer of current market all generally adopts random ink-jet technology.Random mode ink-jet system ink inside is only just sprayed when printing needs, so be also called on-demand.It is compared with continous way, and structure is simple, and cost is low, and reliability is also high, enjoys the favor of consumers in general.
The ink-jet system of continuous circulation. high speed ink droplet can be generated, so print speed is high, can common paper be used.Different print media all can obtain high-quality print result, is also easy to realize colour print.But the structure of this ink-jet printer is compared with random mode, and more complicated: need pressue device to ink, terminal will have retracting device to reclaim not participate in be noted down, and the efficiency of working method is not high enough, and inaccuracy.
Existing random mode ink-jet printer in the future, just frequently can need change print cartridge because of ink when use one section, the trouble that this measure not only causes user to use, and more improves printing cost because of the costliness of print cartridge expense.It is out of ink or print uneven phenomenon that traditional ink-jet printer not there will be spray in ink jet process, find that ink gun enters air after investigation reason, air bag is formed so fail to print ink at nozzle, therefore ink-jet printer air-discharging is also important link, and in the problem that process ink gun enters air, be mostly to take out the print cartridge in printer in reality, ink gun is cleaned draw back the ink in ink gun with needle tubing after, this measure is too complex in operation, also need the discharge air that user is artificial, and effect is undesirable.
Summary of the invention:
The present invention seeks to solve the deficiencies in the prior art, propose the fast and ink feeding system of the uniform printer of ink gun ink-jet of a kind of easy and simple to handle and ink gun ink feed speed, its technical scheme is as follows:
