Leather surface spraying system

Abstract

The invention relates to a leather surface spraying system comprising a conveying unit, wherein the conveying unit is a conveying belt extending along the conveying direction of materials; a scanning unit, a spraying unit and a drying unit are sequentially distributed on the conveying belt along the conveying direction of the conveying belt; and a vacuum adsorption mechanism is also arranged below the spraying unit. The leather surface spraying system has the advantages that a leather surface is dyed by using the spraying unit when being subjected to dyeing treatment , so that the color paste waste is effectively reduced, and the cost is reduced; and a vacuum adsorption unit is arranged when leather is conveyed to the spraying unit and is dyed by ink jet, so that the leather can be kept smooth, the problem that part of leather cannot be dyed because of a wrinkle phenomenon is avoided, and furthermore the leather is successfully dyed.

Description

technical field [0001] The invention relates to the field of leather processing, in particular to a leather surface spraying system. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. With the continuous development of the tanning industry, the application fields of leather are more and more extensive, including domestic leather, national defense leather, industrial and agricultural leather, cultural and sporting goods leather. Flesh removal, grading, measuring and skinning of skins, squeezing and stretching of skins, splitting and peeling, trimming and dyeing, re-moisture and softening, stretching drying, grinding, spray drying and other processes to achieve the finished ...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned spraying machine is spraying and decorating the leather, its nozzle often adopts a high-pressure spraying method to spray the color paste on the surface of the leather. With such a spraying method, a large part of the color paste liquid will be lost. Diffuse directly into the air, but cannot be sprayed onto the leather, so the utilization rate of the color paste is relatively low, and the corresponding cost is also high
