Technical Field

[0001] The invention relates to the technical field of composite leather manufacturing, in particular to composite leather and manufacturing equipment thereof. Background Art

[0002] In today's material field, with the continuous improvement of people's requirements for quality of life and the increasing diversification of application scenarios in various industries, the performance requirements for leather products are becoming more and more stringent. Although traditional natural leather has a unique texture and a certain durability, its output is difficult to meet the growing market demand due to the limitation of raw material supply, and natural leather has shortcomings in some special properties. At the same time, artificial leather came into being. Although the early artificial leather can make up for the problem of insufficient natural leather production to a certain extent, its texture, durability and functional integration are still unsatisfactory. For example, the appearance of early artificial leather is stiff and unnatural compared to natural leather, with poor touch, low wear resistance and folding resistance, and cannot withstand high-intensity use for a long time.

[0003] In order to break through these limitations and meet the market's higher performance and quality requirements for leather products, composite leather technology has gradually emerged. By organically combining materials with different characteristics, it aims to integrate the advantages of various materials to create new leather products that are both beautiful, durable and highly functional. However, some existing manufacturing equipment still has many problems in the production of composite leather. For example, during the gluing process, the storage and coating methods of glue are rough, and the glue is prone to precipitation and drying, resulting in uneven gluing, affecting the bonding effect between the layers of materials, and it is impossible to flexibly adjust the gluing position and range according to the different widths and materials of the leather, and the adaptability is poor.
