[0002] Printing technology has played an important role in people's lives and work. Printing technology covers various methods and processes for transferring images, text and designs to paper or other media. It is widely used in many fields, including publishing, advertising, packaging, artistic creation, etc. Inkjet technology is a commonly used printing technology that sprays ink onto the medium by controlling the position and method of ink spraying to form images or text.

[0003] Industrial inkjet equipment will perform a maintenance operation called ink pressing during the daily maintenance of the nozzles. The principle of ink pressing is to squeeze the ink out of the nozzle holes through positive air pressure, thereby cleaning the nozzle holes and preventing clogging. This process involves all nozzles and color channels on the equipment and may need to be performed multiple times in succession. In this process, some ink will be squeezed out of the nozzles.

[0004] The current solution for collecting and recycling these inks is that all inks are collected uniformly through a waste ink tank, and then discharged into a waste ink barrel and handed over to relevant qualified units for recycling and treatment.

[0005] Therefore, those skilled in the art provide an industrial digital color printing equipment ink recycling system to solve the problems raised in the above background technology. Summary of the invention
