Device for preparing dyeing liquid for leather dyeing and processing

Abstract

The invention discloses a device for preparing a dyeing liquid for leather dyeing and processing, wherein the device includes a dyeing liquid preparation main body and a raw material grinding device;the raw material grinding device is fixed on the top of the dyeing liquid preparation main body; the dyeing liquid preparation main body is made of a stainless steel material, the top of the dyeing liquid preparation main body is provided with a water inlet, the bottom of the dyeing liquid preparation main body is provided with a discharge port, and the discharge port is provided with a valve. A dyeing raw material entering the interior of the dyeing liquid preparation main body is ground and crushed by the raw material grinding device mounted at the top of the dyeing liquid preparation main body, the uniformity of the fineness of raw materials used in a dyeing liquid and particle size of powder used in the dyeing liquid are ensured, the dyeing raw material and water dissolving speed is accelerated, the preparation speed of the dyeing liquid is accelerated, flowing mixing of water and dyeing raw materials in the dyeing liquid preparation main body are promoted by stirring and air blasting, and the preparation speed of the dyeing liquid is further accelerated.

Description

Technical field: [0001] The invention relates to the technical field of leather processing equipment, in particular to a dyeing solution preparation device for leather dyeing. 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. Texture and gloss, feel comfortable. Leather needs to be dyed in the process of production and processing, but the preparation speed of the existing dyeing solution for leather dyeing is relatively slow, which affects the efficiency of leather dyeing and processing. In the process of preparing the dyeing solution, the dyeing raw materials are directly mixed with water, and the dyeing raw materials The raw materials with larger particles in the solution cause a longer dissolution tim...

Leather needs to be dyed in the process of production and processing, but the preparation speed of the existing dyeing solution for leather dyeing is relatively slow, which affects the efficiency of leather dyeing and processing. In the process of preparing the dyeing solution, the dyeing raw materials are directly mixed with water, and the dyeing raw materials The raw materials with larger particles in the solution cause a longer time to dissolve in water, resulting in a longer preparation time of the staining solution
