Abstract

The invention discloses a circulating ink supply system, an ink-jet printing device and ink-jet printing equipment. The circulating ink supply system comprises a circulating assembly, and a secondary ink box of the circulating assembly is connected to an ink outlet of a main ink box. An ink supply pump, a first flow pressure sensor, a plurality of nozzles, an ink return distributor, a second flow pressure sensor and an ink return pump are sequentially connected, the ink return pump is connected to an ink inlet of the secondary ink box, the ink supply pump is connected to an ink outlet of the secondary ink box, and the first flow pressure sensor is in communication connection with the ink supply pump. The second flow pressure sensor is in communication connection with the ink return pump; an ink outlet of a first return valve of a liquid discharging assembly is connected to an ink discharging pump, a second return valve is connected to an ink outlet of the ink discharging pump, and an ink outlet of the second return valve is connected to a waste ink box and the main ink box; and a cleaning assembly comprises an ink receiving disc and a negative pressure air knife. According to the circulating ink supply system, the picture quality of ink-jet printing can be improved.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to a circulating ink supply system, an inkjet printing device and inkjet printing equipment. Background technique [0002] At present, with the development of science and technology, automation is more and more widely used in the field of electronic processing and manufacturing. As an important part of production and manufacturing, printing has attracted more and more attention from people. The function of the ink supply system is like the blood circulation system of the human body. It needs to be kept in a stable state to make the whole human body system function normally. In the related art, the pressure in the ink supply system is unstable, which will lead to unstable flow and temperature viscosity of the ink during the printing process, resulting in poor printing effect. Contents of the invention [0003] The main purpose of the present invention is to provide a ...
