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...

Examples

Embodiment A

[0053] The ink filling method includes the following steps:

[0054] Step 1: Connect the ink filling machine to the cartridge body, close the first on-off valve, open the second on-off valve and the third on-off valve, and vacuum the interior of the cartridge body for 1S;

[0055] Step 2: Close the second on-off valve and the third on-off valve, open the first on-off valve, and inject the ink of the ink container into the ink cartridge through the ink injection port under the action of air pressure and keep it for 1S until the ink fills the ink cartridge;

[0056] Step 3. Close the first on-off valve and separate the ink refilling port from the ink refilling port of the ink cartridge, and then open the second on-off valve, hold it for 1 second, close the second on-off valve, and discharge the ink outlet from the ink cartridge Mouth separation

[0057] Step 4. Seal the ink filling port and ink outlet of the ink cartridge.

Embodiment B

[0059] The ink filling method includes the following steps:

[0060] Step 1. Connect the ink filling machine to the cartridge body, close the first on-off valve, open the second on-off valve and the third on-off valve, and vacuum the inside of the cartridge body for 30 seconds;

[0061] Step 2: Close the second on-off valve and the third on-off valve, open the first on-off valve, and inject the ink of the ink container into the ink cartridge through the ink injection port under the action of air pressure and keep it for 30S until the ink fills the ink cartridge;

[0062] Step 3. Close the first on-off valve and separate the ink refilling port from the ink refilling port of the ink cartridge, then open the second on-off valve, hold it for 30S, close the second on-off valve, and discharge the ink outlet from the ink cartridge Mouth separation

[0063] Step 4. Seal the ink filling port and ink outlet of the ink cartridge.

Embodiment C

[0065] The ink filling method includes the following steps:

[0066] Step 1: Connect the ink filling machine to the cartridge body, close the first on-off valve, open the second on-off valve and the third on-off valve, and vacuum the interior of the cartridge body for 10 seconds;

[0067] Step 2: Close the second on-off valve and the third on-off valve, open the first on-off valve, and inject the ink of the ink container into the ink cartridge through the ink injection port under the action of air pressure and keep it for 15 seconds until the ink fills the ink cartridge;

[0068] Step 3. Close the first on-off valve, and separate the ink refilling port from the ink refilling port of the ink cartridge, and then open the second on-off valve, keep it for 20 seconds, close the second on-off valve, and discharge the ink outlet from the ink cartridge Mouth separation

[0069] Step 4. Seal the ink filling port and ink outlet of the ink cartridge.
