Abstract

The invention provides an ink box ink injection method for printer ink jet ink box circulation regeneration. Firstly, through positive pressure ink injection (a positive pressure pump), ink is injected through ink box ink injection holes according to the quantification regulated by an ink box, and after ink injection, two problems are generated. According to the first problem, some bubbles are generated between the ink and a sponge at the bottom of the ink box, and the printing quality is affected; according to the second problem, within a period of time of ink injection, the ink does not completely permeate into the sponge, and the ink box cannot instantly perform printing ink outputting. In order to solve the problems, after ink injection, air is pumped and the ink is discharged out of ink outlets in the bottom of the ink box through negative pressure ink pumping (a negative pressure pump) until the ink can be directly pumped out of the ink box by 1 ml to 2 ml. A circulation loop (please see an attached map) is formed in the ink injecting process of the ink box, after ink injection, a small amount of ink in the bottom of the ink box and the generated bubbles are pumped into the sponge through the negative pressure until the ink and the bubbles are exhausted out of the ink box. According to the implementation, the two problems existing in ink injecting of the ink box for a long time are solved, and the quality is improved.

Description

Ink box regenerating without circulation of bubbles refilling method

Technical field

The present invention carries out a kind of method without bubble, high-quality refilling to the ink-jet printer cartridge with ink holder, the production technology of the present invention has improved existing (manual refilling, Vaccum ink filler) infusing ink in ink box, has solved long-standing, the insurmountable sponge ink bleed of infusing ink in ink box, bubble-free 2 large technical barriers.

Background technology:

Print cartridge is the important component part of ink-jet printer, and its quality will directly affect the printing effect of ink-jet printer.Print cartridge is to give ink droplet certain energy by the power generator in print cartridge, make on its precalculated position that is ejected into printing paper, complete printing, the technology of ink-jet printer is the patented product of printer manufacturing firm, only have in the world several producers of minority just to have the ability of manufacturing ink-jet printer, as Japanese EPSON, CANON, the HP of the U.S., LEXMARK, Zhe Si great producer occupies whole world ink-jet printer 90% production share, these producers have spent huge R&D fund really in early stage, just develop inkjet technology, high-leveled and difficult technology also causes the monopolistic behavior of printer manufacturer simultaneously, they reclaim great number R&D costs in early stage, later stage earns under the interests driving of a large amount of profits, by ink-jet printer consumptive material---print cartridge becomes as high price, disposable occupation mode, form high waste, the unreasonable situation of high pollution, the product that only has monopolization, just have irrational occupation mode, in the current whole world, advocate environmental protection, under the theory of saving, this principle has been run counter in the use of printing consumables completely, and 10 years have been continued, this is the very rare market behavior of running counter to economic law, now this present situation should have been changed.

Print cartridge is as the pen, by housing+ink, formed, original-pack producer first manufactures housing, is carrying out refilling and complete the production of print cartridge, and print cartridge is after ink is finished using, housing still can continue to use over 30 times, due to expensive (particularly, with the print cartridge of printhead, black on average surpasses 100 yuan, colored average over 150 yuan) of print cartridge, after once finishing using, abandon, cause great waste and environmental pollution;

Therefore the reasonable manner of the use of print cartridge is exactly---and print cartridge circulation refilling is regenerated, ink box regenerating is just as being used pen, complete the process of print cartridge high-quality refilling---original-pack empty cartridge housing (renewable surpassing 30 times)+high-quality ink+effective refilling technique, just can reach the quality level same with original-pack print cartridge, and the material cost of ink box regenerating is lower than 1 yuan;

But, the refilling technique that ink box regenerating adopts is at present owing to there is no good technological means, existing refilling technology is mainly to adopt manual refilling mode, simple and easy refilling equipment---adopt the mode of Vaccum ink filler to complete more, quality does not generally reach requirement, by client, do not admitted, therefore cause ink box regenerating only to occupy the share of print cartridge market below 10%, the enforcement of this method, can improve greatly the quality level of ink box regenerating, add the low price that circular regeneration has, the advantage of environmental protection, add the running of industrialization, ink box regenerating can become trend, become the mainstream product in the market, to save substantial contribution for country, to lack 90% above print cartridge and abandon pollution on the environment.

Fig. 1 is the production technology schematic diagram adopting without circulation of bubbles refilling method:

Fig. 2 is the manual refilling technique of ink box regenerating:

Technological process---from the pouring ink hole of print cartridge 2., by 1. malleation (adopting syringe), 3. ink is injected to print cartridge, refilling is complete more.

The ubiquitous shortcoming of manual refilling:

1,, owing to reducing the cost and selecting few problem, ubiquity ink quality not good (or not mating with original-pack print cartridge ink), affects the quality level of whole ink box regenerating;

2, different print cartridge, quantity of ink is that different (3ml---40ml), manual refilling can only be by feel, and ink is quantitatively difficult to accurately, and ink adds few reduction number of copies, and ink is added and overflowed ink leak;

3, owing to being covered with air in print cartridge, in refilling process, due to the problem of pressure and refilling speed, in ink bottom, near ink holder place, can produce bubble 4., when can making to print, these bubbles produce broken string phenomenon, affect print quality;

4,5., in partial desiccation state, ink will enter after a while (half an hour-6 hour) and could again all permeate after injecting the ink holder of vacant print cartridge, and during this period, print cartridge can't be printed out of ink, can not use immediately.

Fig. 3 is the Vaccum ink filler technique of ink box regenerating:

Technological process---by negative pressure, from ink hole, 6. the residual China ink of print cartridge is extracted out, the pouring ink hole that 8. negative pressure pump is connected to print cartridge with pipeline 2., 6. and airway the ink hole of sealing print cartridge, start negative pressure pump 8., with negative pressure ink box, vacuumize, reach-80kpa takes out 1-2 minute above continuously, 9. 2. pouring ink hole connect ink via, close negative pressure pump 8., the negative pressure that ink exists by print cartridge inner vacuum state flows into print cartridge automatically, and refilling is complete.

Vaccum ink filler strengths and weaknesses analysis:

1, generally adopt homemade ink, up-to-standard, but do not reach original-pack print cartridge level;

2, be generally to control by computer, can be according to the quantitative refilling of different print cartridges;

3, can not guarantee that 100% without bubble, and operation is very complicated, print cartridge seals very difficult completely, and compression pump and liquid pump need reasonable combination, and because ink has higher corrosivity, the long-term running of equipment faces a very large difficult problem;

4, ink holder is when Vaccum ink filler, and in dry inkless water state, ink will enter the long period (3 hours-12 hours) and could again all permeate after injecting, and greatly affected the use immediately of print cartridge completely.

Summary of the invention

As Fig. 1, the present invention is mainly reflected in after infusing ink in ink box, has increased by the 7. content (negative pressure pumping ink function).

2. 1. technological process---positive pressure pump connect infusing ink in ink box hole by pipeline, startup malleation 1. (positive pressure pump, peristaltic pump etc.) is 3. injected print cartridge by ink, after ink injects, 6. 7. negative pressure pump connect ink outlet port by pipeline, start negative pressure pump and 7. outside print cartridge, send 0.5-1ml ink, send residual air bubble simultaneously.

Advantage without circulation of bubbles refilling method is:

1, the bubble remaining between ink and sponge is removed;

2, allow the quick and complete ink holder that is penetrated into of ink, realize the printing immediately after infusing ink in ink box;

3,, with respect to Vaccum ink filler method, greatly simplified refilling operating procedure;
