The invention discloses a three-impulse control system for ink circuit circulation of a ceramic ink-jet printer. It includes: ink supply assembly and control assembly; ink supply assembly includes ink barrel, main ink tank and auxiliary ink tank; control assembly includes an industrial computer, a control unit, an operation display unit, a temperature sensor, a pressure sensor, a negative pressure control assembly, a flow sensor, three level sensors and a level switch. The invention can realize the cascaded three-impulse control of the negative pressure, positive pressure and flow of the ink path circulation of the ceramic inkjet printer, and improves the stability and printing quality of the ink path system. Moreover, the invention effectively reduces the debugging period, improves the work efficiency, and strengthens the protection of the negative pressure control components. Also, the invention effectively improves the adaptability to various inks.
Description
technical field [0001] The invention relates to an ink path circulation control system of a ceramic inkjet printer, in particular to a three-impulse control system for the ink path circulation of a ceramic inkjet printer. Background technique [0002] Since the ceramic inkjet printer appeared in 2000, due to its unique advantages, it has been widely used in many ceramic manufacturers at home and abroad, and has developed very rapidly. The pattern printing quality of a ceramic inkjet printer is closely related to its ink circulation control system. If the ink circulation control is unstable, it may cause defects such as hanging lines, dripping ink, non-printing, and imperfect printing colors. It will cause problems such as inkjet head clogging. Therefore, the ink circulation control of ceramic inkjet printers is very important. [0003] At present, the ink circulation control technology of ceramic inkjet printers mainly uses control technologies such as high and low speed co...
