Problems solved by technology

Double-chamber ink cartridges are widely used because of their superior performance. However, in the prior art, the original one-way negative pressure or one-way positive pressure ink filling method is still used for the ink filling of this double-chamber ink cartridge. method, but these two methods cannot fill the ink chamber when filling ink, and there is air in the ink chamber, which causes poor ink filling, which leads to low product qualification rate and poor printing effect.

Embodiment Construction

[0017] like figure 1 , figure 2 , image 3 As shown, the present invention relates to a method for filling ink with double ink chambers, which is used for filling ink with double ink chambers 1. The outer sides of the two ink chambers of the double ink chamber ink cartridge 1 are provided with ink filling ports. The ink filling port is blocked by silica gel 2, and the insides of the two ink chambers are connected. The ink filling method comprises the following steps:

[0018] (1) Two-way pumping: use the infusion needle 3, the connection end of the infusion needle 3 is connected to the vacuum pump through the air pipe 4, and the needle end of the infusion needle 3 is inserted into the ink chamber through the silica gel 2 , using the vacuum pump to simultaneously pump air to the two ink chambers until the vacuum values ​​in the two ink chambers reach a set value;

[0019] (2) Two-way ink filling: After the above (1) step is completed, the connection end of the infusion need...

Abstract

The invention discloses an ink filling method of an ink cartridge with double ink cavities, which aims at providing a method for simultaneously filling ink into the two ink cavities of the ink cartridge with the double ink cavities. The ink is filled into the ink cavities, so the ink filling effect is improved. Filling needles are used as filling carriers, and the method mainly comprises the following three steps of 1, bidirectional air suction: inserting the filling needles (3) connected with a vacuum pump into the ink cavities, and simultaneously sucking air from the insides of the two ink cavities until the vacuum value reaches the setting value; 2, directional ink filling: inserting the filling needles (3) connected with an ink filling machine into the ink cavities, and utilizing the negative pressure suction force in the ink cavities to simultaneously carry out bidirectional ink filling on the two ink cavities until the two ink cavities are filled with ink; and 3, extracting the filling needles (3), so as to complete ink filling. The ink filling method is suitable for the field of ink filling of the ink cartridge with double ink cavities.

Description

technical field [0001] The invention relates to an ink filling method, in particular to an ink filling method for an ink box with double ink chambers. Background technique [0002] Ordinary ink cartridges generally use two methods to fill ink. The first is the negative pressure ink filling method, which means that all the air inside the ink cartridge is drawn out, and the ink is sucked into the ink cartridge due to the suction inside the ink cartridge. This method is mostly used for sponge ink cartridges and soft bags. Ink cartridges, etc.; the second is the positive pressure ink filling method, that is, the ink is injected into the ink cartridge by pressure, and the air in the ink cartridge is discharged. This method is mostly used for refillable ink cartridges or continuous supply products. Since the ink filling object is a single-ink chamber ink cartridge, a one-way ink filling method is adopted. However, with the continuous development of printing consumables technology...
