Laser air-extracting microporous sole

Technical Field

The utility model relates to a sole technical field particularly, relates to laser micropore sole of bleeding.

Background

The sole is rather complex in construction and in a broad sense may include all of the materials forming the sole, such as the outsole, midsole and heel. In a narrow sense, only the outsole is referred to, and the common characteristics of the general sole materials should have various conditions such as wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to the foot shape, difficult deformation after shaping, heat preservation, easy moisture absorption and the like, and simultaneously should be matched with the midsole to have the braking function to avoid slipping and easy stopping when the foot is changed during walking. The sole materials are of various types and can be divided into natural base materials and synthetic base materials. The natural bottom materials comprise natural bottom leather, bamboo, wood and the like, and the synthetic bottom materials comprise rubber, plastics, rubber and plastic combined materials, regenerated leather, elastic hardboard and the like.

In the conventional process flow of the composite shoe soles in the market, the bottommost shoe bottom layer is firstly placed in a vacuumized mold, a shoe bottom film is placed above the mold, before foaming raw materials of the foaming layer are poured on the shoe bottom film, the shoe bottom film needs to be heated and softened by a heating box, and then the mold is vacuumized to enable the shoe bottom film to be tightly attached to the shoe bottom layer. However, since the sole layer is generally uneven, air is easily left between the sole film and the sole layer after vacuum pumping, the phenomenon of improper attachment occurs, defective products can occur at a certain probability, and material waste is caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems that the bonding effect of a common composite sole cannot be guaranteed when the sole layer and the sole membrane are vacuumized and bonded, bubbles are easy to remain, defective goods that the sole layer and the sole membrane cannot be completely bonded are generated, and material waste is caused, the laser air-pumping micropore sole is provided.

Laser micropore sole of bleeding, including the sole layer, run through on the sole layer and be provided with a plurality of laser micropores, the laminating has the thin layer in sole layer top, the thin layer top is equipped with the foaming layer.

Further, an adhesive layer is arranged between the sole layer and the film layer.

Furthermore, the bottom of the sole layer is provided with a toothed anti-slip strip, the toothed anti-slip strip and the sole layer are integrally formed, and the laser micropores penetrate through the toothed anti-slip strip.

Further, the top of the sole layer is provided with a positioning and fitting groove.

Furthermore, the laser micropores are transversely arranged into micropore columns, and the micropore columns are uniformly arranged on the sole layer from top to bottom.

The utility model has the advantages that:

1. air between the sole layer and the film layer is fully pumped out by utilizing the micropores, so that the sole layer and the film layer are tightly attached, the product quality is higher, and the yield can be effectively improved; in addition, the original performance of the sole is not affected.

2. Simple manufacture, production efficiency is high, utilizes the common laser drilling equipment on the market to beat a plurality of micropores on the sole layer after, can accomplish compound sole production according to conventional production flow.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, this embodiment provides laser micropore sole of bleeding, including sole layer 1, run through on the sole layer 1 and be provided with a plurality of laser micropores 2, the laminating has thin layer 3 above

sole layer

1, 3 tops on the thin layer are equipped with foaming layer 4.

An adhesive layer 5 is arranged between the sole layer 1 and the film layer 3. The bonding layer 5 is made of bonding materials such as glue, so that the sole layer 1 can be tightly attached to the film layer 3, and the durability of the sole is improved. If the film layer 3 has tackiness after heating, the adhesive layer 5 may be omitted.

The sole layer 1's bottom is provided with dentate antislip strip 6, dentate antislip strip 6 and sole layer 1 integrated into one piece, laser micropore 2 runs through dentate antislip strip 6. The dentate anti-slip strips 6 can improve the grip of the sole layer 1.

The top of the sole layer 1 is provided with a positioning and fitting groove 7. The top of the sole layer 1 is provided with an inwards concave positioning and laminating groove, so that the laminating stability of the sole layer 1, the thin film layer 3 and the foaming layer 4 can be improved.

The plurality of laser micropores 2 are transversely arranged into micropore columns, and the micropore columns are uniformly arranged on the sole layer from top to bottom. Even a plurality of laser micropore 2 that set up can provide even efficient water conservancy diversion effect, and quick exhaust air makes

sole layer

1 and 3 quick inseparable laminating of thin layer when the evacuation between sole layer 1 and thin layer 3.

In actual production, firstly, the manufactured sole layer 1 is placed in laser drilling equipment (common equipment in the market, such as Dachuan DC-640C) for laser drilling, a plurality of laser micropores 2 penetrating through the sole layer 1 are processed in the sole layer 1, the sole layer 1 is placed at the bottom of a shoe mold with a vacuumizing function (such as CN107379382A, a modularized universal sole mold), and if necessary, an adhesive layer 5 is coated on the surface of the sole layer 1. Then, fix thin layer 3 in the middle level, utilize equipment such as oven to heat and soften thin layer 3, to the evacuation between thin layer 3 and sole layer 1, make basement membrane 3 laminate in the surface of sole layer 1. Finally, adding foaming material on the film layer 3, closing the sole mold to enable the foaming layer 4 to react, fix and mold. Because set up laser micropore 2 on sole layer 1, can fully take out the air between sole layer 1 and the thin layer 3, laminating between the two is more inseparable, has improved the yields and the steadiness of sole, avoids remaining the wastrel because of the bubble to appear.

The foregoing is a more detailed description of the present invention, and it is not intended that the present invention be limited to the specific details, since modifications and variations will be apparent to those skilled in the art.
