Abstract
The present invention relates to a method of cleaning ink cartridge of ink jet printer. The ink cartridge cleaning process includes the following steps: opening one pressure relieving hole in the third wall of ink cartridge, pressure injecting hot water into the ink cavity through the ink injecting hole and draining water through the pressure relieving hole and the ink outlet port simultaneously, centrifugally dewatering in a centrifugally dewatering machine, stoving the porous material and sealing the pressure relieving hole. The method comprises following steps: firstly, opening a pressure relieving hole at the bottom of the ink cartridge, wherein the diameter of the pressure relieving hole is greatly larger than total of diameter of the print head orifice, therefore, the washing hot water injected from the ink inlet port can quickly outflow from the pressure relieving hole, so as to reduce the pressure from the washing hot water to the flexible printed circuit board and can effectively prevent the press damage of the flexible printed circuit board. On the other hand, the water can quickly outflow through the pressure relieving hole to speed up the circulation between the washing hot water and deionized water and is favor of washing of cellular material in the ink cartridge. In other words, the above method not only can guarantee the washing effect, but also can prevent the badness of the flexible printed circuit board caused by flow pressure concentrated on the flexible printed circuit board.
Description
Technical Field
The invention relates to a method for recycling printing consumables, in particular to a method for cleaning an ink box for an ink-jet printer.
Background
Referring to fig. 1, a three-dimensional structure of an integrated ink cartridge in the prior art is disclosed. The print head 2 of the integrated cartridge is designed as one piece with the cartridge 1, with the ink chamber containing a porous material, on a first wall of the cartridge there being an ink injection hole leading to the ink chamber, and on a second wall opposite the first there is the print head 2, said print head 2 containing an internal ink ejection element selectively activated by the printer circuitry via a flexible printed circuit board 21 engaging the surface of the cartridge body. Each time an ink ejecting element is actuated, an ink drop is forced to be ejected through a corresponding nozzle on the exposed surface of the printhead 2. The integrated ink box has the advantages that after the use of a client is completed, a certain amount of residual ink is left in the porous material, and after the integrated ink box is placed for a long time, the ink box is not cleaned or is simply cleaned and then filled with the ink for use, so that the following three problems are easily caused: 1. poor printing is caused by dry ink blocking the nozzle; 2. although the colors are the same, the mixed color of the printing is caused after the inks of different manufacturers are mixed; 3. the deterioration of the residual ink causes the quality of the filled ink to change. If the three problems are not solved, the ink box is difficult to meet the use requirements of users after being regenerated. In addition, the process of regenerating the integrated ink box by cleaning the ink box in the prior art finds that the flexible printed circuit board 21 of the ink box is very fragile, and if the regeneration process is improper, the flexible printed circuit board 21 is easy to fall off from the box body, so that the whole ink box is scrapped. Because of the above-mentioned integral ink cartridge itself, if the porous material is taken out of the ink cartridge for cleaning and then put back, or the porous material is replaced with a new one, the following three problems are caused:
1. the method of cleaning the porous material and then putting back the porous material can cause that the porous material and the filter screen arranged at the position of the ink cavity, which leads to the channel opening of the printing head, are difficult to be completely sealed, thereby causing hidden troubles such as ink break in printing and the like;
2. the method of replacing a new porous material is adopted, so that the adsorption force/purity of the porous material is difficult to ensure;
3. the two methods both need to bond the top cover and the clapboard again, have hidden troubles of ink leakage and color mixing, and have troublesome operation.
Disclosure of Invention
The invention mainly aims to provide an ink box cleaning method which does not damage an ink box and has better cleaning effect;
to achieve the above-mentioned object, the present invention provides a method for cleaning an ink cartridge,
the print head of the ink cartridge is designed integrally with the ink cartridge, the ink chamber of which is filled with a porous material, the first wall of the ink cartridge is provided with an ink injection hole leading to the ink chamber, and the second wall opposite to the first wall is provided with a print head comprising an internal ink ejection element selectively activated by a printer circuit via a flexible printed circuit board engaged with the surface of the cartridge body;
wherein,
the method comprises the following steps:
a third wall parallel to the second wall is provided with a pressure relief hole;
warm water is injected from the ink injection hole under positive pressure to clean the ink cavity, and water is discharged from the pressure relief hole and the ink outlet of the ink box simultaneously;
centrifugal dehydration is carried out by a centrifugal dehydrator;
drying the porous material;
and sealing the pressure relief hole.
To achieve a better cartridge cleaning effect:
the diameter of the pressure relief hole is 1-3 mm.
The temperature of the warm water is 20-50 ℃.
The rotating speed of the centrifugal dehydrator is 1000-3000 r/min.
The specific process of drying the porous material is as follows: and inserting a needle tube from the ink injection hole, introducing hot air and drying the ink box to a rated weight. The distance between the needle tube head and the filter screen is 9-12 mm; the temperature of the hot air is 10-50 ℃.
The specific process of sealing the pressure relief hole is to heat the pressure relief hole to more than 20 ℃ by using hot melt adhesive to seal the pressure relief hole.
According to the ink box cleaning method, the pressure relief hole is formed in the bottom of the ink box, the diameter of the pressure relief hole is far larger than the sum of the diameters of the ink jetting holes of the printing head, so that the cleaning warm water injected from the ink injection port can flow out of the pressure relief hole rapidly, the water pressure of the cleaning warm water on the flexible printed circuit board (namely the printing head) of the ink box is reduced, the flexible printed circuit board can be effectively prevented from being damaged by the water pressure while the flushing pressure on the porous material in the ink cavity is increased, namely the water can flow out rapidly through the pressure relief hole, the circulation of the cleaning warm water and the deionized water in the ink box is accelerated, and the cleaning of the porous material in the ink. The method can ensure the cleaning effect and avoid the bad condition of the flexible printed circuit board caused by the concentration of water flow pressure on the flexible printed circuit board. The cleaning effect can be effectively improved by controlling the temperature of the cleaning warm water, and the service life of the centrifugal dehydrator can be protected on the premise that the rotation speed of the centrifugal dehydrator is controlled to ensure thorough dehydration.
