Manufacturing methods of new leather layer type shoe heel and shoe sole, and shoes

Abstract

The invention discloses a manufacturing method of a new leather layer type shoe heel. The manufacturing method comprises the following stepsof(1) providing a shoe heel body; (2) coating or spraying aside surface of the shoe heel body with a layer of glue; (3) spraying a layer of leather powder made of genuine leather on the side surface, with the glue, of the shoe heel body, and adhering the leather powder to the shoe heel body through the glue to form a leather layer; (4) carrying out polishing treatment on the leather layer formed on the shoe heel body; and (5) printing the polished leatherlayer with oil paint to form printed layers, wherein the printing layers are ofa strip-shaped structure and are distributed on the leather layer at intervals. The leather powder is adopted to form the leather layer, so that the effect of coating with the whole leather can be achieved, and the positive beneficial effects of low cost, environmental protection, high production efficiency and easy manufacturing are also achieved. Meanwhile, the invention further discloses a manufacturing method of a shoe sole, and shoes.

Description

technical field [0001] The invention relates to a method for manufacturing shoe components and shoes, in particular to a method for manufacturing heels and soles and shoes made by the method. Background technique [0002] Mammalian skin (ie, dermis) is formed of two layers, the epidermis and the dermis, which have different tissue structures. The skin obtained from such animals is depilated, and the epidermis is removed to obtain the dermis. The dermis mainly contains criss-cross collagen fibers, and the collagen fibers are the main component to maintain the excellent physical strength properties of the leather. According to its organizational structure, the dermis is divided into the superficial papillary layer (i.e., the top layer of skin) and the inner reticular layer (i.e., the second layer of skin), and the papillary layer contains grains, which have the inherent characteristics of animals. Embossed pattern and smooth and graceful appearance. After tanning, dyeing, et...

Problems solved by technology

[0007] Through long-term accumulation of production experience and extensive research, the applicant has summed up the three major defects of the existing heels covered with leather: (1) because the covered leather must be a whole, it needs to be covered from the whole Cutting out the stretched leather for covering will produce a large amount of leftovers during the cutting process, which cannot be utilized, greatly wasting resources and increasing costs; at the same time, since the covered leather is all genuine leather, the well-known genuine leather They are all derived from animals, and a large amount of leather is used and wasted, which is neither environmentally friendly nor ecological; (2) the leather is pasted on the heel body by hand, and the side of the heel body is mostly in an irregular shape. Therefore, the cut leather is also in a corresponding irregular shape, and workers need to spend more time to align the leather and the heel body when pasting, so as to ensure that the cut leather can be completely covered The covered side of the heel body is inefficient and labor-intensive, and because the leather material needs to be pressed by workers during the pasting process to ensure that the leather material can be firmly pasted on the heel body, but in the actual operation process In the process, often due to the different strength of the workers and the non-uniformity of finger pressing, after the leather material covers the heel body for a period of time, due to the unevenness and insufficient pressure when pasting, the local leather material will bulge. , thus causing the shoes that are used to beautify and modify people's temperament to appear extremely unattractive, and then lead to being abandoned, wasting resources and polluting the environment; The shape of the heel is not a regular geometric shape. In order to save leather, most of them are often cut manually, but it will take a lot of time to cut the leather manually. If the leather is cut automatically, although the efficiency is improved, but due to the It comes from animals, so the leather is not in a regular shape. Automatic cutting cannot accurately plan the use of the entire leather according to the overall shape of the leather, which will cause more waste of leather than manual cutting.
