Abstract

The invention discloses an ink circulation method. An ink storage device, and a first cartridge, a circular printing head and a second cartridge which are connected circularly are arranged; the ink storage device is connected with the first cartridge; in a main ink path, the ink is conveyed to the first cartridge from the ink storage device; in a first circular ink path, the ink flows through thefirst cartridge, the circular printing head and the second cartridge sequentially through negative pressure; and in a second circular ink path, the ink in the second cartridge is conveyed to the firstcartridge through negative pressure. In comparison with the existing large circulation, the ink can be kept to flow quickly, the circulation path is short, and precipitation is not formed easily. Anink stick is also added on the basis of small circulation as buffer, the pressure changes of the second cartridge are reduced, and the flow speed of the ink flowing through the printing head can thusbe stabilized.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an ink circulation method and a system thereof. Background technique [0002] The circulation print head is a new type of industrial print head. Its principle is to let the ink be squeezed out when it flows through the nozzle hole. Fluidity, designed for extreme industrial inkjet printing, has the characteristics of fast speed, high precision and adaptability to various types of inks. It can effectively solve the problem of precipitation of special inks, and eliminate ink bubbles to ensure the quality of printed patterns; applicable inks include solvent, UV, water-based, oil-based and ceramic inks, etc. For example, the Seiko RC1536GS nozzle supports eight-level grayscale printing. Compared with four-level gradient and six-level gradient, it is more efficient and quick to save ink; it can output ink droplets of different sizes from 13-100PL, and the ignition frequency of a sing...
