Automatic ink loader for computer print cartridge and ink loading method

Abstract

The invention relates to an automatic ink adding machine for a printing ink box and an ink adding method thereof. The automatic ink adding machine comprises a pipeline, a vacuum distributor, a vacuum valve, an ink measuring pipe, a residue pump can, a residual liquid can, a vacuum pump or compressor which are arranged in a casing, a vacuum watch, a residual ink pump connector, an ink injection connector, an ink box fixture which are arranged at the outside of the casing, an air-gas separator, an ink measuring pump, a display screen, a keyboard, a control unit and an electromagnetic valve including a negative ink injection valve, a first positive pressure valve, a second positive pressure valve and a residual ink pump valve. The automatic ink adding method comprises the following steps: 1. clamping the empty ink box to the fixture; 2. starting the vacuum pump; 3. opening the corresponding electromagnetic valve, and vacuumizing the ink measuring pipe and the ink box; 4. setting the ink application value; 5. opening the ink measuring ink pipe of the corresponding position and pumping the ink to the corresponding ink measuring pipe; 6. determining negative pressure ink adding or positive pressure ink adding and injecting the ink into the empty ink box. The machine and the method of the invention have the advantages of convenient clamping and high ink adding efficiency, thus facilitating the management of a plurality of ink adding chain stores, improving the ink adding speed of a soft ink bin and ensuring that the ink box with crazing can be reused.

Description

technical field [0001] The invention relates to computer consumable equipment, in particular to an automatic ink filling machine for printing ink cartridges and an ink filling method thereof. Background technique [0002] The applicant in this case filed an application in 2005 and obtained the patent (Patent No. ZL200520071495.3) of "Computer Printing Cartridge Vacuum Ink Refilling Machine" authorized in 2006, which provides a new technical solution for refilling old ink cartridges. Adopting the technical method of vacuum ink filling, there is no need to make holes in the old ink cartridge when adding ink. When the ink cartridge is not damaged, the residual ink is sucked out and the new ink is poured into the empty ink cartridge, so that the quality of the regenerated ink cartridge is almost the same as that of the new ink cartridge. No difference, greatly reducing printing costs. At the same time, the recycling of old ink cartridges effectively utilizes resources, greatly ...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned ink filling machine has low efficiency for adding ink to soft ink tanks; it cannot be recycled for ink cartridges with microcracks; and for ink filling of large quantities of ink cartridges, there is a low degree of automation and relatively cumbersome operations. The work efficiency is not high enough; if there are many ink-filling chain stores, the above-mentioned ink-filling machine is not convenient for computer chain management
