Technical Field

The invention relates to the technical field of synthetic leather, in particular to a kneading device for concave-convex textures on the surface of microfiber leather.

Background

The kneading pattern of the synthetic leather or the two layers of leather is realized by the action of water, temperature and mechanical force, so that the base cloth or the two layers of leather shrink to drive the surface resin film to shrink, and the concave-convex feeling of the pattern is clearer. And because the nondirectional nature of shrink, the surface decorative pattern produces the irregularity similar to genuine leather, and the effect is more lifelike. The process of mechanical softening is carried out while the grain is kneaded, the fibers are looser under the action of mechanical force, and the base cloth or the double-layer leather becomes softer. By kneading the patterns, the surface patterns are improved, the softness of the leather is improved, and the comprehensive improvement of hand feeling and patterns is realized.

The graining process is completed in a graining machine, and the leather realizes rolling or rolling and throwing combined movement in the equipment, which is similar to the drum action of the leather. The base cloth or the two layers of leather are continuously thrown, collided, rubbed and extruded in the rotary drum to be stretched, compressed, bent and deformed to form the leather.

However, the conventional graining machine is relatively poor in effect, and thus needs to be improved.
