Problems solved by technology

The defect of this detection method is: due to the slow diffusion speed of the ink on the platform and the difficult calculation of the diffusion range, the viscosity of the ink cannot be calculated in time, and it is easy to find that the viscosity of the ink becomes larger after a long time after the calculation. The phenomenon, resulting in a decline in printing effect

Abstract

The invention relates to an ink control device, in particular to an ink viscosity detection device. The ink viscosity detection device comprises an ink inlet, an ink outlet, an overflow chamber, an ink storage chamber and an ink outlet channel. A top opening of the ink storage chamber, a top opening of the ink outlet channel and the ink inlet are all communicated with the overflow chamber, the topopening of the ink outlet channel is higher than the top opening of the ink storage chamber, and the top opening of the ink storage chamber is higher than the ink inlet. A liquid leakage opening is formed in the bottom of the ink storage chamber, a plunger driven by an air cylinder is plugged in the liquid leakage opening, a photoelectric sensor is arranged below the liquid leakage opening, the photoelectric sensor comprises a signal transmitter and a signal receiver, and a vertical liquid column formed in the air after ink leaks out of the liquid leakage opening is located between the signaltransmitter and the signal receiver. According to the invention, real-time online detection of the ink viscosity is realized, the detection efficiency of the ink viscosity is improved, and the accuracy of ink viscosity calculation is ensured.

Description

technical field [0001] The invention relates to an ink control device, in particular to an ink viscosity detection device. Background technique [0002] The control indicators of ink mainly include viscosity, pH value and dryness. Ink viscosity refers to the ability to hinder the movement of other molecules under the influence of its own internal force. Generally, a certain amount of ink is used to flow through the capillary at a fixed temperature (generally 20°C), and the time required is recorded and measured as viscosity. The viscosity of the ink is the main factor that determines the transfer performance, print fastness, penetration and gloss of the ink. If the ink viscosity is high, the color will become darker, the ink consumption will increase, and the drying speed will slow down; if the viscosity is too low, the color will change, and the dots will expand, resulting in a decline in printing quality. The adjustment and control of ink viscosity should start with con...
