Detailed Description

The technical means adopted by the invention to achieve the preset purpose are further described below by combining the accompanying drawings and the preferred embodiments of the invention.

The present invention relates to a sole adhesion method, and more particularly to a sole adhesion method as shown in fig. 1, which includes a preparation step S1, a sealing step S2, a pressing step S3, and a removing step S4, wherein:

preparation step S1: firstly, putting a shoe tree 10 into a semi-finished shoe product formed by combining a vamp 22 and a middle sole, heating the bottom surface of the semi-finished shoe product and the colloid coated on the sole 21, and combining the semi-finished shoe product and the sole 21 through the colloid to form a shoe 20; the glue used in this step can be water glue or hot melt glue, when the glue is water glue, the water glue can be coated on the bottom surface of the semi-finished product of the shoe, the front surface of the sole 21 and the shoe edge 211, and the shoe edge 211 is annularly arranged on the periphery of the sole 21; if the glue is a hot melt glue, the hot melt glue need only be applied to the front surface of the sole 21.

Bonding step S2: as shown in fig. 2, the shoe 20 prepared in step S1 is placed in a sealable sealed bag 30 having a check valve 31, the sealed bag 30 can be a zipper bag made of plastic material, the shape of the sealed bag 30 can be similar to the shape of the shoe, air in the sealed bag 30 is pumped out by a motor (not shown) to present a vacuum negative pressure state, the sealed bag 30 is contracted by the negative vacuum pressure, and the sole 21 and the edge 211 of the sole 21 between the sealed bag 30 and the shoe last 10 are tightly pressed on the bottom of the semi-finished shoe.

Pressurization step S3: as shown in fig. 3, the sealed bag 30 with the shoes 20 inside is placed in a forward pressure tank 40 in the sealing step S3, the forward pressure tank 40 can further squeeze the sealed bag 30 by adjusting the internal pressure, so that the sole 21 and the welt 211 are further attached and squeezed to the bottom of the semi-finished shoe product, and further, since the volume of the forward pressure tank 40 is not changed, the internal pressure of the forward pressure tank 40 is increased, so that the internal temperature is increased together, and the glue is melted, so that the sole 21 and the welt 211 can be further bonded to the bottom of the semi-finished shoe product by the melted glue.

In the aforementioned step S3, a shoe-shaped fixture 50 can be placed inside the positive pressure barrel 40, so that the sole 21 of the shoe 20 can be flush against the shoe-shaped fixture 50, thereby enhancing the contact between the sole 21 and the edge 211 and the bottom of the semi-finished shoe product, and the adhesion between the sole 21 and the edge 211 can be completed after the aforementioned steps are completed.

Taking out step S4: the positive pressure barrel 40 is first decompressed, and then the sealed bag 30 is opened under an atmospheric pressure and the shoe 20 is taken out.

In the aforementioned taking-out step S4, for the sole 21 with the bent surface, there may be a problem that the sole 21 and the welt 211 cannot be firmly attached to and pressed against the bottom of the shoe semi-finished product, and to avoid this problem, as shown in fig. 4, before the sealed bag 30 is opened under an atmospheric pressure, a rod 61 is pressed against the sealed bag 30 corresponding to the heel of the shoe tree 10, and then a rod 62 is pressed against the sealed bag 30 corresponding to the toe of the shoe tree 10, so that the attachment degree between the sole 21 and the welt 211 and the bottom of the shoe semi-finished product can be improved by the pressure applied by the shoe tree 10.

As shown in fig. 1, the process of the second preferred embodiment of the present invention is substantially the same as the first preferred embodiment, with the difference that: in the sealing step S2, after the shoe 20 is placed in the sealable sealed bag 30 having the one-way valve 31, the sealed bag 30 is first placed in the positive pressure barrel 40, and the air in the sealed bag 30 is pumped out by the motor through the pipeline to be in the negative pressure vacuum state, so that the sole 21 and the welt 211 are tightly pressed on the bottom of the semi-finished shoe; in the pressurization step S3, the vacuum sealed bag 30 is further pressed by adjusting the internal pressure of the sealed bag 30 in the sealing step S2, so that the sole 21 and the welt 211 are further pressed against the bottom of the semi-finished shoe product.

Through the foregoing steps, the efficacy enhancement of the present invention comprises:

1. through the shrinkage of the sealing bag body 30 generated under the negative pressure vacuum pressure and the extrusion of the positive gas pressure to the sealing bag body 30 and the characteristics of soft material and the like of the sealing bag body 30, the deformation of the joint of the sole 21, the shoe edge 211 and the semi-finished shoe product caused by the direct extrusion of the mechanical hard force and the mutual displacement between the sole 21, the shoe edge 211 and the semi-finished shoe product can be effectively avoided, and the shoe can be effectively produced.

2. The invention does not need to produce a pressing step through a large machine, and the adhesive material can adopt water glue or hot melt adhesive, so the operation process is simple, the cost is reduced, and the invention is suitable for small and medium-sized enterprises.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
