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, and most ink filling machines are vacuum ink filling machines that use the principle of liquid level control for quantitative ink filling control, found in the production process There are mainly the following disadvantages: 1. The three probes for detecting the liquid level signal detect the high liquid level, the middle liquid level and the low liquid level respectively, and the ink filling amount is controlled by adjusting the height difference between the high liquid level and the middle liquid level; The ink is sucked into the dosing syringe with negative pressure, the ink is easy to bubble during the ink pumping process, and the bubbles floating on the surface of the ink will affect the detection of the probe, resulting in inaccurate ink dosing
2. The amount of ink is adjusted by adjusting the height difference between the high liquid level probe and the middle liquid level probe through the screw. This method is not intuitive and the operation is cumbersome
3. Ink cartridges are precision industrial products, each of which has corresponding process requirements. The ink itself also has requirements such as conductivity, PH value, and surface tension. The probe for liquid level detection is a charged body, which may Causes ink to change unpredictably
