Ink cartridge for digital jet printing

Abstract

The invention discloses a digital spray printing ink box which structurally comprises an ink box body, a nozzle, a nozzle wafer, a buckling frame and an ink feeding valve, wherein the ink box body iscomposed of a shell, a sliding mechanism, a recovery box, a particle guiding pipe, a filter screen, a cleaning mechanism and an isolating ventilating frame. The sliding mechanism drives the cleaning mechanism to clean the filter screen so as to prevent the nozzle from being blocked, so that a printing stripe or a serious broken line is avoided; the particle guiding pipe is cooperated with the recovery box to collect ink solidified particles, so that cleaning is facilitated, and secondary blocking is also prevented; and a blocking net is utilized to separate ink from the solidified particles. The digital spray printing ink box with the structural design avoids the situation that impurities in the ink blocks the filter screen to cause blocked ink supply, and a heating element of the nozzle is indirectly caused not to be cooled timely and is burnt truly.

Description

technical field [0001] The invention relates to the field of ink cartridges, in particular to an ink cartridge for digital jet printing. Background technique [0002] Hand-held inkjet printers, also known as portable inkjet printers, are a type of spraying that can be used for digital, English, Chinese or various trademark patterns, and the most important thing about this handheld inkjet printer is the ink tank, because the ink tank contains chips, and the cost The cost is high, so generally when the ink is used up, the ink cartridge will not be replaced, but the ink will only be added. Some inks are of poor quality and contain a lot of impurities, and will not directly block the nozzle. The most direct consequence is that the ink supply is not smooth, and indirectly the heating element of the nozzle cannot be cooled in time and is actually burned. Such a nozzle cannot eject ink droplets even if it is open. When the nozzle burns out, the nozzle compensation technology also m...

AI Technical Summary

Problems solved by technology

1. The technical solution uses the first brush and the second brush to continuously clean the filter structure so as to avoid the clogging of the filter. This method consumes a lot of energy and is not suitable for portable inkjet machines; 2. The impurities in the ink are scraped off by the first brush and the second brush. Although it can avoid accumulating in the filter, the impurities will remain in the box. When the ink is continuously replaced, the concentration of impurities will become higher and higher, and finally Also can only replace the cartridge, resulting in a waste of resources
