Problems solved by technology

This kind of ink cartridge, after the ink in it is exhausted, because the ink flow direction in the ink outlet is controlled by the one-way valve from the inside to the outside, it cannot refill the ink. If the ink is injected once, the sealing structure of the ink filling port will be damaged, and more air will remain in the ink storage chamber of the ink cartridge, and the ink injection volume will hardly reach the original design capacity.
As a result, the air remaining in the ink storage chamber will enter the nozzle part on the printing car

Embodiment 1

[0034] see figure 1 , 2 , 3, 4, 5, the ink-jet printer ink box structure that regeneration method of the present invention is suitable for. image 3 , 4 In 5, the placement posture of the ink cartridge is the same as that in the working state, and the ink outlets for receiving the ink supply needles of the inkjet printer are all pointing vertically downward.

[0035] The components of the ink cartridge A mainly include: a box body 1, a cover 2, two films 3, 4 and a micro-integrated circuit chip 5 for storing ink information.

[0036] The box body 1 is in the shape of a flat rectangular box, and its longest and widest side wall is removed to be in an open state, forming an opening 1011 . Its interior is separated by several partitions, and the end faces of these partitions facing the opening 1011 are basically on the same plane. An elastic lever 1017 extending obliquely upward is provided near the end of the outer surface of the widest and shortest side wall of the box body...

Embodiment 2

[0060] For the inkjet printer ink cartridge with the above structure, another method can also be used for recycling. The method employs the following sequence of process steps:

[0061] First, on the side wall 1037 whose direction is parallel to the ink flow direction in the ink outlet 102 and whose position is between the ink outlet 1012 and the first one-way valve 1023, open the first ink storage chamber 1013 and communicate with it. Through hole 1038 for external atmosphere (see Figure 4 , 5 ).

[0062] Secondly, remove the residual ink in the inner cavity of the ink cartridge A. The specific measure is to keep the end of the through hole 1038 facing the external environment in a downward facing posture, put the ink cartridge A into a sealed container, and extract the air in the sealed container to the negative pressure inside it. When the value reaches -720mmHg~-750mmHg, keep the pressure for 1 minute to 3 minutes and restore the pressure of the sealed container to the...

Abstract

The invention discloses an inkjet ink box regenerated method which includes the following sequence steps: opening an ink-output port, taking out and washing an internal one-way valve; putting down the ink-output port, putting an ink box into a negative pressure vessel, recovering to the atmosphere pressure after the pressure is kept for a plurality of minutes; setting a through hole which is communicated with the inner cavity in the lateral wall of the ink box and sealing the through hole by a silica saeb salam; sealing the ink box after pumping vacuum by the ink-output port, inserting an ink-impletion needle into the through hole and injecting ink into the inner cavity of the ink box, loading the one-way valve into the in-situ of the ink-output port according to the raw condition, getting a regenerated ink box after sealing and packing. The recycling purpose can also be realized by opening the ink-output port, washing the one-way valve which is used near the ink-output port and substituted by the newly-arranged through hole. By adopting the method, the ink box recycling efficiency is high, and the rate of finished product reaches more than 85 percent.

Description

technical field [0001] The invention relates to a method for regenerating an ink cartridge used in an inkjet printer, especially for the separate arrangement of the print head and the ink container. A soft film material is bonded to the rigid ink cartridge frame as one of the side walls of the ink cartridge, so as to The corresponding one-way valve respectively controls the opening / closing state of the ink outlet and the air guide port, and its interior is divided into a plurality of interconnected chambers. The regeneration method of the empty ink cartridge of the inkjet printer. Background technique [0002] For inkjet printers, the ink source is usually provided by the ink container, the ink is transported to the print head through the corresponding ink flow pipe, and the ink is ejected from the print head nozzle to the recording medium such as paper under the drive of the print signal. Complete the recording of characters or graphics. Common commercially available inkje...
