Background

The cow head layer leather is the skin on the top layer of the cow body, and is mainly used for manufacturing leather shoes, leather clothes, high-grade leather pieces and the like due to the high-quality conditions of wear resistance, high gloss, uniform leather color and the like.

Because the intradermal grease is lost in the production process of the leather, the intradermal fibers are bonded together and hardened, and the surface of the leather needs to be coated with a fatting agent and covered with a plastic cloth for sealing, so that the leather recovers the original flexibility and elasticity, and the production of the leather is facilitated.

However, the existing waterproof frosted leather for the ox head layer mainly has the following problems in the production process: 1. leather need soften when using preparation article, paints the surface in required leather with fatting agent through the mode of artifical paining usually to make it resume original compliance and elasticity, but the in-process of paining need dip in many times and get the fatting agent, thereby leads to work fatigue to influence machining efficiency easily, and paints fatting agent volume on the in-process brush unstable, leads to easily paining inhomogeneously, influences whole compliance.

2. After the leather is coated with the fatting agent, plastic cloth needs to be covered, so that the fatting agent slowly permeates into the leather, and the plastic cloth is covered by rolling and covering through manpower or machines; artifical inefficiency, and the machine roll extrusion covers the in-process, the plastic sheeting on the hob bar can reduce gradually to lead to hob bar and leather apart from the increase, and then make roll bar increase the power of dragging of plastic sheeting among the roll extrusion process, lead to the plastic sheeting to tear from the leather easily, influence the parcel of leather.
