Cleaning device, washing type nozzle cleaning system, and digital ink-jet printer

Abstract

The invention discloses a cleaning device. When the device is used, clean water is input to washing channels through a water inlet hole on a water suction nozzle, after clean water is fully filled in the washing channels, the clean water in the washing channels clean jet nozzles of the nozzles to wash off residual printing ink on the nozzles. Using a method to clean the nozzles by clean water prevents scratch of surfaces of the nozzles and reduction of service life of the nozzles caused by direct rigid cleaning by plastic springs or a stainless steel scraper. The device can conveniently clean dried ink on the nozzles. In conclusion, the washing type nozzle cleaning system eliminates various residual ink on the surfaces of the nozzles without damaging the nozzles, preventing the ink from influencing printing effect and the nozzles from being burnt. The invention also discloses a washing type nozzle cleaning system, comprising nozzles, a nozzle base board, a bed frame, a moving device, and a cleaning device. The invention also discloses a digital ink-jet printer, comprising the washing type nozzle cleaning system.

Description

technical field [0001] The invention relates to the technical field of digital inkjet printing equipment, in particular to a cleaning device, a water-washing cleaning nozzle system and a digital inkjet printing machine. Background technique [0002] Digital inkjet printing machine is a new type of printing equipment, which adopts non-contact printing mode, and prints by spraying ink onto the surface of the medium through the nozzle. Digital inkjet printing machines are widely used because of their small equipment footprint, flexible drawing, less manpower required, and no environmental pollution problems. [0003] However, since digital inkjet printing directly sprays ink onto the surface of the medium from the nozzle, after a long time of work, there will be residual ink on the surface of the nozzle, which will affect the printing effect if it is light, and burn the nozzle if it is serious. Remove residual ink. [0004] At present, there are two main ways to clean the noz...

AI Technical Summary

Problems solved by technology

The scraper type cleaning is directly rigidly cleaned by plastic shrapnel or stainless steel scraper. This cleaning method requires extremely high assembly accuracy, and it is easy to scratch the surface of the nozzle. Long-term use will greatly damage the service life of the nozzle; negative pressure air suction Cleaning is done by opening a gap in a plastic inner cavity and cleaning by suction, but this method is not suitable for easy-drying ink, because the ink dries too fast and will directly solidify on the surface of the nozzle instead of being sucked away, thus affecting printing. The picture effect, long-term use, the cleaning effect will become worse and worse
