Background

The process of treating the naked leather with the tanning agent to change the naked leather into leather is called tanning, the tanning process mainly comprises two important steps, firstly, the tanning agent is uniformly and fully permeated into the deep layer of the inner part of the leather, and then the tanning agent permeated into the leather has a chemical reaction with protein, namely a combined process, in order to enable the two steps to be better and more efficiently carried out, a rotary drum device is mostly adopted for industrial leather making to accelerate the two processes, and vacuum tanning test researches prove that the utilization rate of the tanning agent can be improved by more than 50% by reasonably introducing a vacuum mechanism under the condition of reducing the dosage of the tanning agent by a small liquor ratio compared with the traditional tanning.

However, in order to achieve the purpose of simple design and installation, the traditional tanning drum abandons a vacuum mechanism, only uses mechanical rotation to increase contact to fully mix tanning agents and furs, but the time and the tanning agents consumed by the mode are far longer than those of the vacuum drum, and the traditional drum cannot automatically unload materials, so that the feeding and discharging of the materials need manual input, the working efficiency is further limited, and the cost is increased.
