Abstract

The invention belongs to the field of leather tanning, and particularly relates to a leather moisture regaining and folding method. The method is carried out in cooperation with a leather moisture regaining and folding device. The leather moisture regaining and folding device comprises a main machine frame, the main machine frame is provided with a main motor, the output end of the main motor is fixedly provided with a large rotating shaft, a large roller is arranged outside the large rotating shaft, and twenty large roller branch air channels are evenly formed in the large roller. A large roller main air channel is arranged in the large rotating shaft, a water tank is arranged below the main machine frame, the main machine frame is provided with an arc-shaped shell, a detection and liquid spraying mechanism is arranged on the upper portion of the inner arc face of the arc-shaped shell, a water spraying nozzle is arranged on the arc-shaped shell, water uniformizing mechanisms are symmetrically arranged on the portions, on the two sides of the water spraying nozzle, of the arc-shaped shell, and a small rotating shaft is arranged at the feeding position of the arc-shaped shell. The small rotating shaft is provided with an air suction traction mechanism, a tanning liquid box is arranged on the outer arc face of the arc-shaped shell and provided with a stirring mechanism, the large roller abuts against a turning plate, and a supporting and folding mechanism is arranged on the lower portion of the turning plate.

Description

technical field [0001] The invention belongs to the field of leather tanning, in particular to a method for regaining moisture and folding leather. Background technique [0002] After fatliquoring and drying, the skin board is very hard. In order to facilitate scraping and softening, it must be properly sprayed with water inside. This process is called "moisturizing". The fur tanned with alum, because of its lack of water resistance, should be coated with alum tanning solution. The smeared fur is folded inside and outside, sealed and placed under pressure overnight to make it absorb water evenly. Then scrape and soften. In the prior art, first, it is impossible to accurately spray the alum tanning solution to the place where there are only furs; second, it lacks a stirring and stabilizing mechanism for the alum tanning solution; third, there is no internal folding mechanism for the fur. Based on the above reasons, this kind of leather rehydration and folding method that can...
