Abstract
The dynamic characteristics of squeeze piezo printhead are studied using reduced frequency model for inks with different viscosity. While piezo inkjet mainly applies in paper printing and graphic output, many new applications have emerged in the last few years. These new applications involve inks with high viscosity. Ink viscosity is a key material parameter in printhead design. In order to take viscous damping into account, reduced frequency model is applied to model the printhead fluid cavity. Squeeze piezo printhead models with different inks (viscosity range from 20 cps to 110 cps) are built using software ANSYS15.0. Meniscus velocity and pressure at the nozzle entrance excited by frequency from 10 KHz to 200 KHz are calculated. Meantime, the velocity and pressure distribution around the first resonant frequency (which is 21250 Hz in the paper) are also calculated. The results reveal that both meniscus velocity and pressure decrease with increasing viscosity. It is notable that ink viscosity affects the printhead dynamic response significantly near resonant frequency. When the exciting frequency is far from resonant frequency, the influence of viscosity is small. The reduced frequency model is a powerful tool for the design optimization of the piezo printhead.
