White ink large character ink-jet printing machine stirring and automatic cleaning system

Abstract

The invention discloses a white ink large character ink-jet printing machine stirring and automatic cleaning system. The white ink large character ink-jet printing machine stirring and automatic cleaning system comprises an ink bottle, a gear pump and a sprayer and further comprises a first three-way valve, a second three-way valve, a waste liquid bottle, a solvent bottle and a vacuum pump, wherein the outlet of the ink bottle is connected with a first opening of the first three-way valve through a pipeline and the gear pump, a third opening of the first three-way valve is connected with a third opening of the second three-way valve through a pipeline, the inlet of the sprayer and the outlet of the sprayer, a second opening of the second three-way valve is connected with the inlet of the waste liquid bottle through a pipeline, an air outlet is formed in the top of the waste liquid bottle, a first opening of the second three-way valve is communicated with an inlet pipeline of the ink bottle, an air inlet is formed in the top of the solvent bottle, and the outlet of the solvent bottle is connected with the second opening of the first three-way valve through a pipeline. According to the white ink large character ink-jet printing machine stirring and automatic cleaning system, different cleaning effects can be obtained through control of the switch combination of the three-way valves. The white ink large character ink-jet printing machine stirring and automatic cleaning system has the advantages of being simple in structure, convenient to operate and free of dead angles in stirring process and cleaning process, enabling a user to select different cleaning modes and being good in cleaning effect.

Description

technical field [0001] The invention relates to a stirring and cleaning system of a white ink large-character inkjet printer. Background technique [0002] The pigment particles contained in the white ink used in the white ink large-character inkjet printer are very easy to form precipitation and dryness, and cause blockage in the white ink path such as the ink chamber of the nozzle, the nozzle, and the ink pipeline. Only a magnetic stirring device can be used for white ink precipitation, but for The dry white ink in the ink tubes, ink chambers, and nozzles cannot be removed. After several hours of paused printing, the nozzles are clogged and the printing quality is greatly reduced, and even the printed content cannot be recognized. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention proposes a stirring and automatic cleaning system for a white ink large-character inkjet printer. [0004] Technical scheme of the present i...
