Printing ink viscosity detection equipment

Abstract

According to the printing ink viscosity detection equipment provided by the utility model, in the working process of the printing ink viscosity detection equipment, a large amount of to-be-tested printing ink is contained in the test box and the printing ink box. The driving air cylinder drives the driving piston to be inserted into the testing box through the driving shaft, part of to-be-tested printing ink in the testing box is injected into the printing ink box through the output port, the output pipe and the injection port, and meanwhile part of the to-be-tested printing ink in the printing ink box flows back into the testing box through the outflow port, the backflow pipe and the backflow port. The detection end of the magnetic switch is used for detecting the reciprocating motion frequency of the driving shaft on the driving air cylinder. It needs to be explained that a function relationship exists between the reciprocating motion frequency of the driving shaft and the viscosity value of the ink; and the control mechanism calculates the obtained reciprocating motion frequency of the driving shaft or compares the obtained reciprocating motion frequency with information in a database to obtain a corresponding ink viscosity value, and the ink viscosity value is displayed through a display. The ink viscosity detection equipment is simple and exquisite in structure and low in cost.

Description

Technical Field

[0001] The utility model relates to the field of ink viscosity detection, in particular to ink viscosity detection equipment. Background Art

[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.

[0003] However, ink viscosity is crucial for ink printing. Low ink viscosity will result in lighter ink color and affect the ink adhesion. Too high ink viscosity will increase printing costs and affect printing quality.
