Description

Technical Field

[0001] The invention relates to the technical field of leather dyeing, in particular to a double-sided roller coating machine used for cowhide production. Background Art

[0002] Leather dyeing is an important step in the leather production process. The leather dyeing effect directly determines the quality and durability of the leather. Uneven dyeing affects the leather's cortical hardness, tensile properties and other parameters. Leather products are prone to deformation, bulging, etc. during subsequent use.

[0003] Leather dyes refer to dyes that have an affinity for leather and can be used for leather coloring. Leather products can be colored with acidic, medium, direct and alkaline dyes, etc. Neutral dyes are the most commonly used when spraying. Dyes are required to be slightly soluble in water and easily soluble in organic solvents such as ethylene glycol, ether, ethanol or dimethylformamide. They are mainly used for spraying coloring of pigskin, cowhide, sheepskin and other leathers.

[0004] However, in the existing leather dyeing process, the leather is pressed by a steel roller and the dye mixture is dipped and coated on the leather. After the leather is pressed by the steel roller, the pressure changes at any time due to uneven force, resulting in uneven distribution of the dye mixture after the leather is dyed, and the excess dye on the leather surface after roller coating affects the uniformity of printing and dyeing.
