Abstract

The invention discloses an ink detection surface tension measuring device for digital printing, which relates to the technical field of ink detection surface tension detection for printing and comprises a bottom plate, a vertical rod arranged on one side of the top of the bottom plate, an adjusting pipe arranged on the upper part of the vertical rod, a cross beam arranged on one side of the adjusting pipe and a silicon piezoresistive sensor arranged at the suspended end of the cross beam, a suspended detection ring is mounted at the detection end of the silicon piezoresistive transmission device, a bearing disc is arranged above the top surface of the fixed cylinder, and a jacking mechanism is arranged in the fixed cylinder; positioning mechanisms are arranged on the periphery of the middle of the inner bottom face of the bearing disc. Through cooperation of the fixing cylinder, the bearing disc and the jacking mechanism, the stability and the constant-speed effect of the bearing disc during lifting are effectively improved, meanwhile, horizontal calibration operation can be conducted on the bearing disc before detection, the situation that the liquid level of to-be-detected ink inclines is avoided, the accuracy of surface tension detection on the ink is effectively improved conveniently, and the detection precision of the surface tension of the to-be-detected ink is improved. And the high efficiency and convenience of surface tension detection on the printing ink are greatly improved.

Description

technical field [0001] The invention relates to the technical field of detecting surface tension of ink for printing, in particular to a device for measuring surface tension of ink for digital printing. Background technique [0002] The surface tension of the liquid means that any molecule inside the liquid receives the same force from the surrounding molecules in all directions and can cancel each other out, so the movement of the molecules inside the liquid does not require any force; the molecules on the surface of the liquid are affected by the molecules inside the liquid The force of the force is much greater than the force of the gas molecules on the other side, so the molecules on the liquid surface have a tendency to automatically migrate to the interior of the liquid. One of the manifestations of this trend is the automatic shrinkage of the liquid surface. This effect is called liquid surface tension. ; [0003] In the detection of inks for digital printing, surfac...

AI Technical Summary

Problems solved by technology

[0003] In the detection of inks for digital printing, surface tension measurement is an important parameter to characterize the properties of inks. When measuring the surface tension of existing inks, most of the measurements are not very automatic. Generally, the container containing ink is placed on the bearing On the tray, the hook of the surface tension measuring instrument hangs the detection ring. When measuring the surface tension, the height of the support tray is generally adjusted by the manual handle, and the support tray is moved down to observe the water column formed between the detection ring and the ink. The surface tension of the cracked ink is measured, but it is inconvenient to correct and adjust the level of the supporting tray before the ink to be tested is supported by the supporting tray and the detection ring is in contact. At the same time, the stability during the manual lifting adjustment of the supporting tray is poor, and the lifting speed is not easy to maintain a uniform state, resulting in the disadvantage of low surface tension measurement accuracy for the ink; therefore, the above problems need to be improved. deal with
