Abstract

The invention provides a bottom material pre-coating machine for a leather waterborne finishing agent and leather surface processing equipment and technology. The bottom material pre-coating machine comprises a rack, wherein the rack is provided with a pressing roller, a tensioning roller and an adhesive tape transmission roller, wherein a conveyer belt for conveying leather to be covered sleeve among the pressing roller, the tensioning roller and the adhesive tape transmission roller; the adhesive tape transmission roller is in power connection with a driving mechanism; the rack is further provided with a finishing roller; the finishing roller is provided with a finishing roller rapid replacement mechanism; the leather surface processing equipment comprises the bottom material pre-coatingmachine; a leather buffing machine is arranged at the upstream of the equipment, and an ironing machine, a roller printing finishing machine, an ironing embossing machine and a slurry spraying machine are arranged at the downstream of the equipment in sequence; the leather surface processing technology comprises the steps of carrying out leather blank buffing, pre-coating a bottom material, ironing a leather blank, rolling a waterborne wet-process material, embossing and carrying out color spraying. According to the bottom material pre-coating machine for the leather waterborne finishing agent and the leather surface processing equipment and technology, the coating quality and efficiency of the bottom material of a waterborne polyurethane leather finishing agent are improved, and the problems that leather easily has an uneven surface and the edge is not ordered when the exsisting equipment utilizes the waterborne polyurethane leather finishing agent to treat leather are solved.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and in particular relates to a primer precoating machine for leather water-based finishing agents, leather surface processing equipment and a process. Background technique [0002] Leather finishing agent is a general term for a class of leather auxiliary agents used to protect and beautify leather on the surface of leather. It is composed of film-forming substances, coloring materials, thinners and other additives in a certain proportion. The basis of paints. Leather finishing agents also play a very important role in the leather manufacturing industry. They can increase the appearance of leather, prolong the service life of leather, significantly improve the quality and grade of leather products, and increase trade value. [0003] At present, the traditional tanning industry is facing great pressure of industrial transformation and upgrading. Traditional leather finishing agents are...
