A kind of artificial leather production and manufacture secondary processing method

Abstract

The invention relates to a secondary processing device used for manufacturing of artificial leather. The device comprises a base, a processing platform fixedly installed in the middle of the upper endsurface of the base, a fine-adjustment slide base mechanism arranged at the upper end of the base, a pair of pulling tensioning mechanisms arranged on the fine-adjustment slide base mechanism and animprinting mechanism fixedly installed on the processing platform. According to the provided secondary processing device, three-dimensional imprinting is conducted on block-shaped artificial leather which is cut and slitted, imprinting of the leather in a pulling and tensioning state can be completed by the device, and it can be ensured that an imprinted pattern is spread with the surface of the leather; the imprinted pattern is prevented from being subjected to resilient deformation with elastic force of the leather, and the attractiveness of the pattern and the consistence of the pattern andan imprinting template pattern are ensured.

Description

technical field [0001] The invention relates to the technical field of leather processing, and specifically proposes a secondary processing method for the production and manufacture of artificial leather. Background technique [0002] Artificial leather is made of various formulations of PVC and PU foamed or coated on a woven or non-woven fabric base. It can be processed according to different strengths, colors, luster, patterns, etc. , has the characteristics of a wide variety of designs and colors, good waterproof performance, neat edges, high utilization rate and cheaper price than real leather, and has been widely used in leather goods production. [0003] The initial processing of artificial leather is generally processed into finished coil materials, and then according to the processing requirements, various secondary processing such as surface painting, block cutting, and pattern printing will be carried out to meet different production and processing requirements.

Problems solved by technology

[0003] The initial processing of artificial leather is generally processed into finished coil materials, and then according to the processing requirements, various secondary processing such as surface painting, block cutting, and pattern printing will be carried out to meet different production and processing requirements. For artificial leather Pattern printing in China is mainly divided into pattern printing methods such as planar printing, three-dimensional printing and three-dimensional embossing. Among them, the three-dimensional embossing of artificial leather mainly embosses the leather directly through a punch with an embossing pattern, but the existing Most embossing machines do not consider that the leather itself has a certain elastic shape, so simply embossing in the embossing process will inevitably cause a certain degree of rebound deformation of the pattern, thus affecting the aesthetics of the embossed pattern, that is, affecting the appearance of the embossed pattern. to the quality of imprint
