Abstract

The object of the present invention is to solve the problem of improving the squeezing of the upper and the midsole in the conventional shoemaking, so as to facilitate the application of the adhesive. Grinding makes the factory dust fly, increases the cost of shoemaking, and is not good for the health of the workers; the adhesive is also a chemical, which is negative for human health. The new invention uses a wire machine on the upper and the back of the midsole. The synchronous car is lifted by a thick line of 0.4~0.6cm to make a curved system structure with irregularities and gaps. In the outsole mold of the shoe making machine, the dissolved liquid-like outsole rubber material that is injected enters the concave and convex portions and the gap, and is closely engaged with the curved system structure. In the close engagement of the upper with the midsole and the outsole, a pair of complete and high-heeled shoes that do not require sanding or application of adhesive are completed.

Description

Wear-free plastic-free leather shoes

The invention relates to the field of shoemaking, in particular to a leather shoe which is free from abrasion and glue, and a shoemaking method for connecting the upper with the midsole and the outsole using a curved system structure.

The existing method of making shoes is to always bond the midsole, the upper and the outsole with a binder. In the process, the upper and the midsole are polished. In addition to the need for labor, a large dust is also polluted, and the adhesive is applied. It is a toxic and harmful chemical component (some manufacturers may use formaldehyde carcinogens), which will harm the health of shoe-making workers and have a certain negative impact on consumers' health.

Another conventional method of making shoes is to manually stitch the upper connected to the midsole with the outsole using thick needlework. Its shortcoming is that the needle speed is slow, unskilled workers will also sew the wrong position, increase the engineering cost or weaken the structure of the leather shoes; and when it rains or walk through the stagnant oil and water area, the needle passes through the midsole, the upper and the outsole hole may Infiltration of rainwater or accumulation of oil and water, causing inconvenience and discomfort to consumers.

The object of the present invention is to solve the problem that the existing shoe is to be ground and the adhesive is used to cause harm to the human body and increase the cost, and a wear-free rubber-free shoe and a shoe-making method thereof are provided.

In order to solve the above problems, the present invention adopts the following method: First, use 0.1~0.3cm The line adopts the curve of the car line machine in the A area of the midsole with a width of 0.5~1.5cm. At this time, the line machine foot pulls out the 0.4~0.6cm thick line synchronously, lifts the curve, forms the concave and convex shape and the gap, and The remaining space in this area continues the curve of the vehicle width of 0.5~1.5cm; Second, the upper is connected with the B area of the midsole after the processing of the first step; Third, the midsole of the connecting upper is placed on the large bottom mold of the melted rubber material. The inside is connected, and then cooled to room temperature to complete the connection of the midsole, the outsole and the upper; wherein the midsole is bounded by 0.4 to 0.6 cm from the midsole edge, and the zone near the midsole is zone B, away from the middle. The area at the bottom edge is area A. The shoe prepared by the above method includes a midsole, an outsole, and an upper connected to the midsole. The midsole is bounded by a distance of 0.4 to 0.6 cm from the midsole edge, and is divided into an area near the edge of the midsole, and is set as the B area; and an area away from the midsole edge is set as the A area; on the A area, The curve of the line width of 0.1~0.3cm is 0.5~1.5cm; the upper is connected with the B area of the midsole through the 0.1~0.3cm line lifted by the thick line of 0.4~0.6cm; the midsole is connected with the upper of the shoe. Immerse in the large bottom mold of the melted rubber and plastic material and join the outsole.

The invention comprises the following beneficial effects: the invention changes the traditional shoe-making method; a method for sewing the upper, the midsole and the outsole without physical means without polishing and bonding, and without using a chemical composition. These shoes are durable and beautiful. The method of the invention only needs about half of the labor of the traditional shoe making method, which greatly saves the labor cost and reduces the production cost. The invention adopts a special treatment on the midsole, with a boundary of 0.4~0.6cm from the midsole edge, and a region near the midsole edge is the B area for connecting the upper, and the area away from the midsole edge is 0.1~ in the A area. 0.3cm cotton thread or nylon thread or cotton nylon hybrid line, according to the formation of the midsole, a circle similar to the "ring" curve, and the width of the curve defining the "ring" is 0.5~1.5cm. The foot synchronously pulls out the thick line of 0.4~0.6cm, lifts the curve, forms the concave-convex shape and the slit, so that the curved system structure with the height of up to 0.5~0.9cm protruding bulge can be formed, so that the processed back surface of the midsole forms a relative concave and convex Shape and gap, this embossing and seam The gap is equivalent to the burr after the sanding of the midsole by the traditional method; the burrs after the sanding of the midsole are scattered and easy to fall off, which is not like the strength of the curved system structure. The structure of the strong curve system is beneficial to the combination of filling the outsole rubber material, so no adhesive is needed. The curved system structure design of the invention is to ensure that the liquid rubber material can be smoothly poured into the concave and convex portions and the gap after being placed in the large bottom mold, and after the solidification, the midsole, the upper and the large can be realized. The stable connection of the bottom eliminates the step of adhesive. In order to further enhance the strength of the joint, the present invention also uses a similar curved system structure in the same manner as the remaining midsole in the "annular" curve, and the remaining midsole can be made in one or more ways. This will further strengthen this connection. This type of connection is also moisture-proof, waterproof, and is not affected by temperature, and has environmentally friendly effects. Since the adhesive is omitted, many negative problems caused by the use of the adhesive are solved.
