Method for cleaning cartridge and cleaning device

Abstract

An ink box cleaning method and cleaning device; the ink box cleaning method comprises that water is infused into the cavity with positive pressure through a vent hole and water is pumped with negative pressure from the cavity through an ink outlet; the water infusion is stopped with positive pressure and then the water pumping is stopped with negative pressure; the ink box cleaning device comprises a base, a set of standing posts, a movable base moving along the standing posts and one or more pipes; every pipe is fixed on the movable base with the injection end equipped toward the base and the other end connected with the water source; a negative-pressure pumping pipe is fixed on the base with the suction end equipped toward the movable base and the other end connected with a negative-pressure generator. The present invention, by adopting negative-pressure water pumping and drainage, boasts of more excellent cleaning and thorough drainage.

Description

technical field [0001] The invention relates to an ink cartridge cleaning method and cleaning equipment, in particular to a cleaning method and a cleaning device used in recycling ink cartridges of inkjet printers. Background technique [0002] In today's society where resources are increasingly scarce and people's awareness of environmental protection is increasing, saving resources and protecting the environment is a basic requirement for industrial development. The recycling of inkjet printer cartridges not only complies with this requirement, but also reduces production costs and user costs. Therefore, more and more manufacturers are reusing the old ink cartridges of recyclable inkjet printers. [0003] For the recycling of empty and old ink cartridges, there is an existing method to wash the entire ink cartridge with water first, and then use centrifugal dehydration technology to remove the ink in the ink cartridge, or after washing, introduce a hot air flow of 1.5 to ...

AI Technical Summary

Problems solved by technology

[0006] The cleaning method and cleaning device for the above-mentioned recycled ink cartridges essentially adopt the process of water inflow and natural water outlet, and the cleaning capacity is very limited, and because the water outlet is small, the internal structure of the recycled ink cartridges is complicated, and the discharge of water is often insufficient, leaving a large amount of residue in the recycled ink cartridges. moisture

For ink cartridges with a built-in sponge, since there is a large amount of residual ink in the sponge, and the sponge has the characteristics of absorbing liquid, the problem of insufficient cleaning and a large amount of residual water is even more prominent
