Reverse roller coating patching machine for sheepskin clothing leather

Abstract

The invention discloses a reverse roller coating patching machine for sheepskin clothing leather. The reverse roller coating patching machine for the sheepskin clothing leather is characterized by comprising a rack, a skin feeding device used for containing and conveying sheepskin, a roller coating area, a water channel part, a water scraping part and a scraping blade part, wherein the roller coating area comprises a coating decoration roller and a rubber roller used for performing roller coating on the sheepskin; the water channel part and the water scraping part are used for controlling thehumidity of the rubber roller; the scraping blade part is used scraping away a coating decoration agent on the protruding portion of the coating decoration roller surface; the skin feeding device is arranged at the skin feeding end of the rack; the upper portion of the roller coating area is provided with the coating decoration roller, and the lower portion of the roller coating area is provided with the rubber roller; a material trough is arranged between the coating decoration roller and the scraping blade part, and the coating decoration roller is used for dipping the coating decoration agent from the material trough; and the water channel part is arranged below the rubber roller, and the water scraping part is arranged on one side of the rubber roller and is used for controlling the allowance of an aqueous solution remaining on the surface of the rubber roller. An existing roller coating machine structure is improved, and due to a corresponding process measure, soft sheepskin can be flatly fed into the roller coating area; and a special mechanism is adopted, the problems of rolling, folding and the like of the sheepskin during reverse roller coating can be eliminated, and afterroller coating of the sheepskin is completed, the sheepskin can flatly and reliably leave the roller coating operation area.

Description

technical field [0001] The invention belongs to the field of leather roller coating equipment and roller coating technology, and in particular relates to a reverse roller coating damage repairing machine for sheepskin garment leather. Background technique [0002] The leather roller coater is a device that uses a set (or more sets) of finishing rollers to operate in conjunction with a conveyor belt or pressure roller to apply a certain amount of finishing agent to the flat leather. The finishing roller of the roller coater is in direct contact with the leather, and the principle of gravure printing is applied to keep the finishing agent in the groove on the surface of the finishing roller, and the excess finishing agent on the surface of the roller is scraped off by a blunt knife. When the finishing roller rotates to contact the leather, the finishing agent remaining in the grooves on the surface of the roller is transferred from the roller to the leather surface, thereby pr...

AI Technical Summary

Problems solved by technology

The reverse roller coater is generally suitable for the treatment of fine-boned shaved leather (such as cowhide sofa leather). For leather with soft hardness and thin thickness (such as sheepskin garment leather), due to the above-mentioned...
