Description

How to make active insoles

Technical field

The invention relates to the technical field of insole processing, in particular to a method for making a movable insole.

Background technique

The movable insole is a freely replaceable insole, which meets ergonomic and hygienic requirements. Because the movable insole is extended along the arc of the sole of the human foot to cover the vertical wall of the sole of the foot, it can stabilize and protect the foot, and can be stuck in the shoe without sliding, and it is easy to clean.

General sports insoles are mostly made of thermoplastic materials (such as EVA, PVC, PE cotton, etc.). Due to their physical properties, these thermoplastic materials often have a high deformation rate due to insufficient hardness, that is, if they are too hard, they will be uncomfortable to wear, and if they are slightly soft, they will be easily deformed.

Contents of the invention

The object of the present invention is to provide a method for making a movable insole in order to solve the above-mentioned deficiencies in the prior art. In the method, thermoplastic materials and non-thermoplastic materials are mixed and processed to form movable insoles, and the excellent physical properties of the thermoplastic materials and non-thermoplastic materials are fully utilized, and their defects are overcome.

A kind of manufacturing method of movable insole of the present invention comprises the following steps and process conditions:

The first step is to paste the formed non-thermoplastic midsole on the thermoplastic substrate, and paste the fabric above the non-thermoplastic midsole, and the fabric is directly pasted on the outer edge of the non-thermoplastic midsole with the thermoplastic substrate;

In the second step, the above materials are pressed into the movable insole according to the shape of the movable insole through a mold, so that the edge of the movable insole is the direct bonding part of the thermoplastic substrate and the fabric, and the non-thermoplastic material midsole is covered in it.

In order to better realize the present invention, the mold includes two parts, an upper mold and a lower mold, and the upper and lower molds directly press the directly pasted part of the thermoplastic substrate and the fabric to make it thermoplastically formed; the thermoplastic substrate includes heating Post-molding can be shaped vinyl acetate copolymer (abbreviated as EVA) cotton, polyvinyl chloride (abbreviated as PVC) cotton or polyethylene (abbreviated as PE) cotton; the non-thermoplastic material includes heated latex sponge, Rubber sponge or polyurethane (abbreviated as PU) sponge; the fabric includes cloth or leather.

Generally, non-thermoplastic materials (that is, materials that cannot be molded after heating the finished product) have defects such as difficult reshaping, high shrinkage rate, non-wear-resistant surface, and high processing cost during the molding process, so they cannot be widely used in the processing and manufacturing of movable insoles. The invention cleverly uses non-thermoplastic material as the midsole, and wraps it in the thermoplastic base material and fabric, which not only overcomes the shortcomings of non-thermoplastic materials, but also greatly reduces the processing cost. The problem of high deformation rate caused by pure choice of thermoplastic materials.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1. The present invention uses thermoplastic materials and non-thermoplastic materials to form the movable insole, and overcomes the problem of high deformation rate of the movable insole caused by the thermoplastic material through the low deformation rate of the non-thermoplastic material.

2. Since the present invention adopts non-thermoplastic material as the midsole of the movable insole, the movable insole made has the advantages of softness, environmental protection, breathability, and deformation resistance.

3. The present invention can realize large-scale industrialized production of movable insoles without traditional manual production.

Fig. 3 is a schematic diagram of the mold pressing the heel part of the movable insole in the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. In fact, in the following examples, EVA cotton, PVC cotton or PE cotton in thermoplastic substrates can completely replace each other, and latex sponge, rubber sponge or PU sponge in non-thermoplastic materials can also completely replace each other, and the implementation effect is still very good. good.

Example 1

The first step is as shown in Figure 1. Paste the molded non-thermoplastic material latex sponge midsole 2 above the thermoplastic substrate EVA cotton 1, and paste the cloth 3 on the non-thermoplastic latex sponge midsole 2. The cloth 3 is placed on the non-thermoplastic latex sponge midsole. The outer edge of the material latex sponge midsole 2 is directly pasted with the thermoplastic substrate EVA cotton 1 (that is, the part shown in the label 4);

In the second step, the above-mentioned materials are pressed into the movable insole according to the shape of the movable insole through a mold, so that the edge of the movable insole is the directly pasted part 4 of the thermoplastic substrate EVA cotton 1 and the cloth 3, and the non-thermoplastic material latex sponge midsole 2 is coated on the in.

As shown in Figures 2 and 3, the mold includes two parts, an upper mold 5 and a lower mold 6, and the mold directly pastes the thermoplastic substrate EVA cotton 1 and the cloth 3 through the vertical surface of the upper mold 5 and the lower mold 6 at the heel of the movable insole. Part 4, making it thermoformed, solves the wrinkles caused by the height drop of the fabric.

Example 2

The first step is to paste the formed non-thermoplastic material PU sponge midsole 2 on the top of the thermoplastic substrate PVC cotton 1, paste the cloth 3 on the non-thermoplastic material PU sponge midsole 2, and the cloth 3 is on the non-thermoplastic material PU sponge midsole 2 The outer edge of the outer edge is directly pasted with the thermoplastic substrate PVC cotton 1 (that is, the part shown in the label 4);

In the second step, the above-mentioned materials are pressed according to the shape of the movable insole through a mold to form the movable insole, so that the edge of the movable insole is the directly pasted part 4 of the thermoplastic substrate PVC cotton 1 and the cloth 3, and the non-thermoplastic material PU sponge midsole 2 is coated on the in.
