Technical Field

The invention belongs to the field of shoemaking, and particularly relates to an upper surface and an upper surface seamless hot-gluing film process.

Background

The existing upper surface is that a plurality of pieces of upper cloth are firstly coated with a hot sticking film, then the plurality of pieces of hot sticking film are sewn and spliced into an upper, and then the plurality of pieces of upper are sewn in a splicing way, the stubble pressing part of the spliced and sewn upper has large friction force on the foot surface, and particularly under the state of long-time walking or running, the influence on the comfort level of people is great, and the sewing procedures for sewing the spliced and sewn upper are multiple, so that a large amount of labor cost is required, and the production efficiency is low.

Disclosure of Invention

In view of the above, it is an object of the present invention to provide an upper and a seamless hot-gluing process for an upper that overcomes or at least partially solves or alleviates the above-mentioned problems.

The invention provides a vamp, comprising:

the upper fabric comprises a front upper fabric, a left upper fabric, a right upper fabric and a rear upper fabric, the rear upper fabric is cut into two halves from the middle and is respectively integrated with the left upper fabric and the right upper fabric, and the front upper fabric, the left upper fabric and the right upper fabric are integrated;

the shoe tip glue film and the shoe upper glue film are attached to the shoe upper cloth, the shoe upper glue film comprises a left upper glue film and a right upper glue film, the shoe tip glue film, the left upper glue film and the right upper glue film are respectively attached to the front upper cloth, the left upper cloth and the right upper cloth in the shoe upper cloth, and the left upper glue film and the right upper glue film respectively extend to the separation positions of the rear upper cloth.

The invention also has the following optional features.

Optionally, the front ends of the left upper glue film and the right upper glue film are connected.

Optionally, a ventilation cut is provided on the upper rubber film.

Optionally, a decorative strip is arranged on the upper rubber film.

Optionally, the thicknesses of the toe glue film and the upper glue film are not more than 1 mm.

The invention also provides a seamless hot-pasting process for the upper surface of the shoe, which comprises the following steps:

s001: adopting polyurethane to prepare a toe cap adhesive film and a vamp adhesive film, placing the toe cap adhesive film and the vamp adhesive film at corresponding positions in a lower template of a mold, and arranging hot-melt shaping cloth on the toe cap adhesive film and the vamp adhesive film;

s002: covering the cut vamp cloth with the toe cap adhesive film, the vamp adhesive film and the hot-melt shaping cloth in a downward mode, and then covering a layer of high-temperature-resistant film on the inner side face of the vamp cloth;

s003: closing an upper template and a lower template of the mold, placing the mold below a pressing plate of pressing equipment, respectively heating the upper template and the lower template of the mold, and taking out the mold;

s004: placing the mold below a pressing plate of cooling equipment for cooling, and taking out the mold;

s005: and taking down the hot-pasted vamp from the die, checking whether the pressing is qualified or not, transferring the qualified product to the next procedure, and reworking the unqualified product.

In S003, the heating temperature of the upper template of the pressing equipment is set to be 240 +/-5 ℃, the heating temperature of the lower template is set to be 130 +/-5 ℃, and the pressing time is 50 +/-5S.

In S004, the cooling temperature of the cooling device to the die is 0 +/-5 ℃, and the pressing time is 20 +/-5S.

The upper surface and the seamless hot-pasting film process of the upper surface adopt the integral upper cloth, and the toe cap glue film and the upper glue film are pasted on the upper cloth in a hot-pasting manner at one time, the integral upper cloth can avoid the occurrence of a stubble pressing part on the upper, the integral wearing comfort of the finished shoe is improved, the sewing process is reduced, the labor cost is saved, and the production rate is improved.
