Parameter optimization of roller squeezing of leather semi-finished products
Abstract
The problem of optimizing the parameters of roller squeezing of a semi-finished leather product is posed in the article. The problem is solved by an experimental study of the residual moisture content in a semi-finished leather product. An empirical model of the residual moisture content in a semi-finished leather product depending on the load intensity, radius and velocity of the rollers is developed. The methods to calculate the optimal parameters of roller pressing of semi-finished leather products, taking into account the specific pressure were developed; these methods make it possible to scientifically formulate the parameters of roller pressing of semi-finished leather products. It was determined that the best effect of load intensity is observed in squeezing machines with low velocities and small diameters. It was found that with an increase in the specific pressure, the residual moisture content in the leather semi- finished product decreases and asymptotically approaches a certain value.
