fig. 2 is a schematic cross-sectional view of a highly conformable and breathable insole of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
Refer to fig. 1 and 2. The utility model provides a highly coincide and ventilative shoe-pad, includes shoe mold layer 1, goes up mould layer 2 and filling layer 3, and shoe mold layer 1 is equipped with holding chamber 11, and holding chamber 11 department is located to filling layer 3, and the edge of shoe mold layer 1 is fixed with the edge of last mould layer 2, and filling layer 3 is located between shoe mold layer 1 and the last mould layer 2, and the shape of filling layer 3 and last mould layer 2 all is unanimous with user's sole shape. In the actual use process, the shoe mold layer 1 and the upper mold layer 2 can be integrally molded by plastic injection; the shoe mold layer 1 is provided with an accommodating cavity 11 which is convenient for the filling layer 3 to be placed and filled.
The filling layer 3 comprises cork dust and a hot melt adhesive, and the weight ratio of the cork dust to the hot melt adhesive is 1: 2-4; the particle size of the cork dust is 1-3 mm. Wherein, the particle size of hot melt adhesive is close with the particle size of cork bits, the homogeneous mixing of cork bits and hot melt adhesive of being convenient for guarantees that the hot melt adhesive can evenly permeate between the cork bits at melting in-process.
The melting point of the hot melt adhesive is 50-100 ℃. Therefore, when the highly-inosculated and breathable insole is manufactured, the soft wood chips and the hot melt adhesive are uniformly mixed and then filled in the accommodating cavity 11, and then the periphery of the upper mold layer 2 and the periphery of the shoe mold layer 1 are fixed through glue bonding or line sewing. After the shoe mold layer 1 and the upper mold layer 2 are fixed, the insole is heated, when the temperature reaches about 50 ℃, the hot melt adhesive starts to melt, the hot melt adhesive uniformly permeates into gaps of the soft wood chips, then the insole is placed into the shoe without the insole, and a user wears feet into the shoe and then walks normally. At the moment, the user acts the sole on the insole, and due to the liquidity of the hot melt adhesive during melting and the gaps among the soft wood chips, the shapes of the filling layer 3 and the upper die layer 2 can be attached to the shape of the sole of the user, so that the high coincidence of the sole and the insole is realized. When a user walks, the insole is slowly and naturally cooled, and the soft sawdust is fixed with the shoe mold layer 1 and the upper mold layer 2 by the hot melt adhesive to realize sizing.
Because contain the soft saw-dust in the filling layer 3 to make the pliability reinforcing of shoe-pad, and can realize ventilative through the gap between the soft saw-dust, improved gas permeability and antibacterial, and effectively prevented the shoe-pad fracture from appearing, improved life.
Go up the surface of mould layer 2 and be equipped with cotton layer 4, cotton layer 4 is fixed on the upper surface of last mould layer 2, can improve the comfort level with the contact of user's sole. The cotton layer 4 may be replaced by other breathable and soft materials.
The front parts of the shoe mold layer 1, the upper mold layer 2 and the filling layer 3 are provided with air holes 5 which are communicated. Therefore, the air holes 5 are arranged, so that the air permeability can be further improved, and the comfort level in use is improved.
Now, the manufacturing method of the insole is described in detail as follows:
a method for manufacturing a highly-inosculated and breathable insole comprises the following steps:
s01, uniformly mixing the cork dust and the hot melt adhesive according to the weight ratio of 1: 2-4;
s02, filling the soft wood chips and the hot melt adhesive into the accommodating cavity on the shoe mold layer;
s03, fixing the upper mold layer and the shoe mold layer and fixing the upper mold layer and the shoe mold layer through gluing;
s04, heating the fixed upper mold layer and the shoe mold layer to fully melt the hot melt adhesive, and then integrally placing the upper mold layer and the shoe mold layer into a shoe without an insole;
s05, enabling a user to penetrate feet into the shoes, enabling the soles of the feet to act on the heated upper mold layers, enabling the user to walk normally to enable the upper mold layers to be matched with the soles of the feet, and taking out the upper mold layers and the shoe mold layers after the upper mold layers and the shoe mold layers are naturally cooled and shaped to obtain the insoles;
and S06, forming air holes on the front part of the insole obtained in the step S05.
Therefore, by adopting the steps, the insole can be highly matched with the sole of a corresponding user, when the insole is naturally cooled and shaped in the walking of the user, the walking posture of the user can be combined, the insole bulge and the spine can be shaped when the sole is firstly attached to the insole, so that the bulge is smooth and does not stab the foot, the ventilation and bacteriostasis effects can be achieved through the cork dust, the manufacturing is convenient, and the applicability is high.
In some embodiments, step S04 is to put the upper mold layer and the shoe mold layer into a sealed bag and then put into water with a temperature higher than 50 ℃ for heating. Therefore, the insole can be heated uniformly and conveniently. In order to realize the rapid melting of the hot melt adhesive, the upper mold layer and the shoe mold layer which are put into the sealed bag can be put into water with the temperature of 100 ℃ for 5 minutes, so that the hot melt adhesive in the filling layer is fully melted.
In some embodiments, the temperature at which the user acts in step S05 is 50-100 ℃. Therefore, the fit degree between the insole and the sole is high, and the comfort level in use is improved. In order to facilitate the safer function of the user's foot, the user's foot may wear a stocking and then act on the insole, thereby fitting the insole to the sole of the foot. The heated insole is put into a shoe without the insole, a user wears the shoe to walk normally after the shoe is put on, the insole is slowly and naturally cooled, the hot melt adhesive is gradually solidified, and the insole is matched and shaped.
The cork dust can also be made of other soft materials with air permeability, such as Chinese herbal medicines.
The soft wood chips and the hot melt adhesive can be mixed and then filled into a strip breathable bag which is smaller than the particles of the melt adhesive and the soft wood chips, such as a non-woven bag, and then the bag is filled into the accommodating cavity on the shoe mold layer.
The insole obtained by the manufacturing method has the advantage of high coincidence with the sole of a user, and is filled with the soft wood chips, so that the insole is good in air permeability and bacteriostasis, high in flexibility and greatly improved in comfort level in use.
