摘要：
In printing processes, printing ink temperature and viscosity had a great influence on the printing quality. Based on the thermal elastohydrodynamic lubrication, the energy of the ink layer, the thickness of the intermediate layer and the temperature of the ink layer in the contact areas of the two ink rollers were calculated by using MATLAB. The distribution of ink temperature was studied at different locations along the contact zones between the layer thickness of a soft and a hard ink roller. The effects of loads, roll speeds and the ink materials on the maximum temperature of the intermediate layers were studied. The results show that the temperature of the intermediate layer ink is the highest at the different positions along the thickness direction of the intermediate, and the temperature is lower near the two rollers. With the increases of the loads, the maximum temperature rise of the intermediate layer increases. With the increases of the roll speeds, the temperature of the intermediate layer of the contact zones between the two rolls is not changed greatly. With the increase of the elastic modulus of the soft roll, the temperature rise of the intermediate layer is increasing. © 2018, China Mechanical Engineering Magazine Office. All right reserved.
