Problems solved by technology

After the above-mentioned integrated ink cartridge is used by the customer, there is still a certain amount of residual ink in the porous material. After a long period of storage, it will be used without cleaning or simply cleaned, which will easily cause the following three problems: 1. 2. Although the colors are the same, inks from different manufacturers are mixed, resulting in color mixing; 3. The quality of the filled ink changes due to the deterioration of the residual ink
[0003] 1. The method of cleaning the porous material and putting it back will make it difficult to completely seal between the porous material and the filter screen set at the channel opening from the ink chamber to the print head, resulting in hidden dangers such as printing ink breakage;
[0004] 2. It is difficult to guarantee the adsorption / purity of porous materials by replacing them with new porous materials;
[0005]3. Both of the above two methods need to re-glue the top cover and partition, which may cause ink leakage and color mixing, and the operation is also troublesome

Embodiment Construction

[0027] A method for regenerating ink cartridges, comprising the steps of:

[0028] (1) Referring to Figure 2, three pressure relief holes 3 with a diameter of 1-3mm are opened at the bottom of the ink cartridge;

[0029] (2) Positive pressure injection of warm water with a temperature of 20°C-50°C from the top ink filling port, so that the warm water flows out from the pressure relief hole 3 and the ink outlet of the ink cartridge at the same time. Generally, it is better to clean until the water flowing out is clear and transparent;

[0030] (3) Use a centrifugal dehydrator to dehydrate and reset, and the speed of the centrifugal dehydrator is controlled at 1000 rpm-3000 rpm;

[0031] (4) Dry porous materials. The specific drying method can be realized in the following two ways: ①Insert the needle tube from the ink injection hole on the top, and the needle tube head is 9-12mm away from the filter screen, and the temperature is 10-50°C. Dry to the rated weight; ②Put the ink c...

Abstract

The present invention relates to process 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 printing head simultaneously, centrifugally dewatering in a centrifugally dewatering machine, stoving the porous material and sealing the pressure relieving hole. The process has low pressure of cleaning hot water on the flexible printed circuit board of the ink cartridge and high cleaning effect.

Description

technical field [0001] The invention relates to a method for recycling printing consumables, in particular to a cleaning method for ink cartridges used in inkjet printers. Background technique [0002] Referring to FIG. 1 , it discloses a three-dimensional structure of an integrated ink cartridge in the prior art. The print head 2 and the ink cartridge 1 of this integrated ink cartridge are designed as one body, and porous material is housed in its ink cavity, and an ink filling hole leading to the ink cavity is arranged on the first wall of the ink cartridge, and the second wall opposite to the first wall Above is located a printhead 2 containing a number of internal ink ejection elements which are selectively activated by the printer circuitry via a flexible printed circuit board 21 which engages the surface of the cartridge. Each time an ink ejection element is activated, ink drops are forced out through corresponding nozzles on the exposed surface of the printhead 2. A...
