Ink filling device and ink filling method

Abstract

The invention provides an ink filling device and an ink filling method. The ink filling device comprises a casing. A plurality of ink containers are contained in the casing. An ink box holder and a controller are further disposed in the casing. The bottom of each ink container is communicated with an ink box mounted on the ink box holder through an ink supply pipe. The controller is electrically connected with a vacuum pump. The top of each ink container is communicated with the vacuum pump through a vacuum pipe. The ink container corresponding to each ink box is communicated with one first solenoid valve disposed on the vacuum pipe, and the first solenoid valves are in one-to-one correspondence to the ink boxes. The vacuum pump is communicated with a second solenoid valve through a relief pipe. The ink filling method includes: after the ink boxes are disposed on the ink box holder, switching off the second solenoid valve and the first solenoid valves corresponding to the ink boxes not disposed, switching on the first solenoid valves corresponding to the ink boxes already disposed, allowing the controller to control startup of the vacuum pump, turning off the vacuum pump after vacuuming, and allowing the controller to turn on the second solenoid valve. The ink box can be filled with ink conveniently at low cost by the ink filling device and method.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to an ink filling device and an ink filling method for filling ink cartridges. Background technique [0002] When the inkjet printer is working, the ink cartridge containing the ink is used to provide the ink source for the inkjet printer, and the ink is transported to the inkjet head through the corresponding ink flow channel, and the nozzles set on the inkjet head are driven by the printing signal. Jetting onto recording media such as paper to complete the recording of characters or graphics on the printing media. [0003] According to the configuration relationship between the inkjet head and the ink cartridge, the ink cartridge includes two types: an integral ink cartridge and a split ink cartridge. The inkjet head of the integrated ink box is integrated with the ink containing cavity, and the inkjet head is arranged on the ink outlet of the ink box. The inkjet head of the ...

AI Technical Summary

Problems solved by technology

It can be seen that the operation of using the existing ink filling device to fill a single ink cartridge will be very complicated, and it is necessary to use a fake ink cartridge as an auxiliary device, which is inconvenient for the user to operate, and also leads to a higher cost of using the ink filling device
