Ink filling machine and ink filling method for recycled ink cartridge

Abstract

The invention discloses an ink filling machine of a regenerative ink box, and an ink filling method. The ink filling machine comprises an ink feeding apparatus and an ink introducing apparatus. The ink feeding apparatus comprises an ink filling interface; an ink container provided with an opening for adding ink; and an ink filling pipe, wherein one end of the ink filling pipe is immersed in ink of the ink container, the other end of the ink filling pipe communicates with the ink filling interface, and a first switch valve arranged on the ink filling pipe is close to the ink filling interface. The ink introducing apparatus comprises an ink discharging interface; a waste ink container; a vacuum pump communicating with the waste ink container; and an ink introducing pipe, wherein one end of the ink introducing pipe communicates with the ink discharging interface the other end of the ink introducing pipe communicates with the waste ink container, and the ink introducing pipe is successively provided with a second switch valve and a third switch valve. According to the invention, the ink can be rapidly and simply injected into the ink box through a vacuum-pumping mode, and through control of the second switch valve and the third switch valve, the ink in the ink filling port area of the ink box is enabled to go into the internal area of the ink box.

Description

Technical field [0001] The invention relates to the field of ink filling for the recycling and reuse of ink cartridges. More specifically, the present invention relates to an ink refilling machine and an ink refilling method for regenerating ink cartridges. Background technique [0002] With the development of society, it is increasingly advocated to turn waste into treasure, and discarded ink cartridges pollute the environment. The non-degradable plastic shell causes white pollution, water pollution caused by colored ink, and black and colored powders. Air particles are polluted. For the recycling and reuse of discarded ink cartridges, the ink cartridges must be refilled. However, the quality of the refilling operation directly affects the utilization of the remanufactured ink cartridges. Especially for the EPSON 9 contact series ink cartridges, the requirements for the refilling operation are compared. Because of its complicated internal structure, the use of conventional vacu...

Problems solved by technology

[0002] With the development of society, it is more and more advocating turning waste into treasure, and the discarded ink cartridges are very polluting to the environment. Their non-degradable plastic shells cause white pollution, water pollution caused by colored inks, and black and colored powders. Air particle pollution, and for the recycling and reuse of discarded ink cartridges, the ink cartridges must be filled with ink, but the quality of the ink filling operation directly affects the utilization of the recycled ink cartridges, especially for the EPSON9 contact series ink cartridges, the requirements for the ink filling operation are relatively High, because of the complex internal structure, the use of conventional vacuum ink filling method is likely to cause unrecognized ink cartridges, insufficient ink or ink dripping and other undesirable phenomena, the product qualification rate is less than 80%, the main reason is that there is a sensitive ink detection device inside the ink cartridge , so research on an effective ink filling machine and ink filling method will help the development of recycled ink cartridges
