Printing ink preparation equipment

Abstract

According to the printing ink preparation equipment provided by the utility model, the preparation diaphragm pump pumps external raw ink through the raw ink input nozzle, and the external raw ink is pumped into the mixing tank through the collecting pipe. The gravity device detects the weight of the raw ink in the mixing tank, and the control mechanism calculates the amount of the solvent to be added according to a preset raw ink-solvent ratio. The blending diaphragm pump is used for pumping an external solvent through the solvent input nozzle and pumping the external solvent into the mixing tank through the collecting pipe. And the solvent pumped into the mixing tank and the raw ink are mixed in the mixing tank. When the ink needs to be output, the mixing tank discharges the ink through the collecting pipe and the output nozzle. It needs to be explained that in the operation process of the blending mechanism, the pumping pump inputs lubricating oil in the lubricating oil filter into the air source input end of the blending diaphragm pump through the lubricating pumping pipe, the exhaust end of the blending diaphragm pump exhausts waste gas into the lubricating oil filter through the lubricating backflow pipe, and the lubricating oil in the waste gas is filtered out by the lubricating oil filter; and therefore, recycling is realized.

Description

[0002] Ink is an important material used in printing. It prints or sprays patterns and texts on substrates. Ink includes main ingredients and auxiliary ingredients, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of binders, pigments, fillers, additives and solvents. It is used for various printings such as books and periodicals, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of inks have also expanded and increased accordingly. The development of inks and printing plates are accompanied by each other, because if the two do not match, the imprint will be unclear, the ink film will fall off, and the printing quality will be affected.
