Parameter optimization of roller squeezing of leather semi-finished products

Calculation formulas for determining the energy-power parameters of roll mechanisms, such as the forces created by the roll gripping devices, the torque, and the power required to rotate the rolls were derived in the study. It was revealed that the radii of the rolls and the thickness of the processed material have the greatest influence on the energy-power parameters. Reducing the roll radius and material thickness makes it possible to reduce the gripping force related to a decrease in the length of the contact zone. As the radius of the roll decreases, the torque decreases as well due to the decrease in the radius of action of the resulting friction force.

The study is devoted to the determination of the technological parameters of roller squeezing machines; these parameters determine the efficiency of the process, product quality, and the environmental situation of production. A mathematical model for the distribution of hydraulic force in roller machines has been obtained. The formulas for calculating the removed and residual moisture of the processed material are determined. It was found that the value of residual moisture depends on the value of the angle where the moisture changes position.

The main parameters of the contact curve of each roll are its shape and length, and the extent of the slip and no-slip zones. Analytical dependencies were obtained that determine the parameters of the contact curves of the rolls of technological machines. It was revealed that at the beginning of the contact zone the skin points are distant from the roll covering point, in the zone at the end of the contact zone it is ahead of it. At the end of the contact zone, the angle between the corresponding points of the skin layer and the roller coating is equal to the modulus of the difference between the lag and advance angles.
