[0001] The utility model relates to the technical field of shoe uppers, in particular to an ultrasonic punching shoe upper. Background Art

[0002] The perforations on traditional shoe uppers can be formed during weaving, or by post-processing such as laser and electric engraving. However, in actual application, it is found that the perforations are easy to fall apart around the penetration area, and the perforation structure is unstable. The finished shoe upper structure often requires overlock coil reinforcement, which affects the shoe upper structure and makes it less aesthetically pleasing. Summary of the Invention

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An ultrasonically perforated shoe upper comprises a shoe upper body, on which a breathable structure having a plurality of perforations is arranged. The perforations include a through-hole area and an edge-sealed area. The through-hole area has an arbitrary shape. The edge-sealed area is distributed along the edge of the through-hole area. The perforations are recessed inwardly on the shoe upper body, and the surface of the shoe upper body presents a three-dimensional surface.

[0010] A preferred technical solution: The upper body is a double-layer structure, including a surface layer and a bottom layer, the surface layer is connected to the bottom layer, and the perforated penetration area penetrates the surface layer and the bottom layer.

[0011] A preferred technical solution: The upper body is a multi-layer structure, including a surface layer, a bottom layer and several intermediate layers. The surface layer is connected to the intermediate layer, the bottom layer is connected to the intermediate layer, and the perforated penetration area penetrates the surface layer, the intermediate layer and the bottom layer.

[0023] Example 1

[0024] like Figure 1-Figure 2 As shown, this embodiment provides an ultrasonically punched shoe upper, including an upper body 10, and a breathable structure with a plurality of perforations 3 is provided on the upper body 10. The perforations 3 include a through-area 31 and an edge-sealing area 32. The through-area 31 is of any shape, and the edge-sealing area 32 is distributed along the edge of the through-area 31. The perforations 3 are recessed inward on the upper body 10, and the surface of the upper body 10 presents a three-dimensional surface. The breathable structure here refers to that formed by the perforations 3. In fact, the fabric layer constituting the upper body 10 itself can also have a certain degree of breathability. The edge-sealing area 32 has an adjacent edge with the through-area 31. After the edge-sealing area 32 in this embodiment is punched by the ultrasonic punching machine, a corresponding cut edge is formed, without any miscellaneous edges or excess thread ends. The edge-sealing forms a closed loop, making the structure of the perforations 3 more stable.

[0025] The ultrasonic punching shoe upper is punched by an ultrasonic punching machine to form a perforation 3. If a circular hole is required, the penetrating area 31 is circular during punching, and the edge sealing area 32 is correspondingly circular (hollow); the edge of the punching structure formed by the ultrasonic punching machine does not need to undergo post-process stitching treatment, no thread ends will appear, it is not easy to fall apart, and the structure is highly stable; when punching, the ultrasonic punching machine will contact the surface of the shoe upper.

[0026] Ultrasonic punching is commonly used in mask production, but is less commonly used in shoe upper preparation. Traditional equipment can form a perforated 3 structure on the shoe upper, but the style and structural stability of the perforated 3 structure are poor. The principle of ultrasonic punching is usually to drive the lower mold to vibrate and heat through an ultrasonic transducer, and then cooperate with the upper mold to punch the shoe upper. The required size and shape of the shoe upper can be achieved by adjusting and replacing the mold according to needs. Ultrasonic punching machines are flexible and more flexible, and ultrasonic punching makes the shoe upper cutting more precise and the quality more stable. In contrast, if lasers or electric engraving are used to form perforations 3, the area around the penetration area 31 is easy to fall apart. When preparing the shoe upper, it is often necessary to reinforce the seam coil, which affects the shoe upper structure and makes the aesthetics poor.

[0027] Furthermore, the perforation 3 is formed by an ultrasonic punching machine.

[0028] Furthermore, the upper is melt-bonded by the ultrasonic punching machine, and after punching, the edge of the perforation 3 of the upper forms a smooth melted edge, and the edge of the cross section of the hole of the perforation 3 is a flat surface.

[0029] Furthermore, a perforation 3 area is set at any local position of the upper body 10, and the perforations 3 on the perforation 3 area are arranged at equal intervals.

[0030] Furthermore, the upper body 10 is a double-layer structure, including a surface layer 1 and a bottom layer 2 , the surface layer 1 is connected to the bottom layer 2 , and the through area 31 of the perforation 3 penetrates the surface layer 1 and the bottom layer 2 .

[0031] Example 2

[0032] This embodiment provides an ultrasonically punched shoe upper, which differs from the first embodiment in that the shoe upper body 10 is a single-layer structure.

[0033] Example 3

[0034] This embodiment provides an ultrasonically punched shoe upper, which differs from Example 1 in that the upper body 10 is a multi-layer structure, including a surface layer 1, a bottom layer 2 and several intermediate layers, the surface layer 1 is connected to the intermediate layer, the bottom layer 2 is connected to the intermediate layer, and the penetrating area 31 of the perforation 3 penetrates the surface layer 1, the intermediate layer and the bottom layer 2.

[0035] Example 4

[0036] This embodiment provides an ultrasonically punched shoe upper, which differs from Example 1 in that the upper body 10 is a multi-layer structure, including a surface layer 1, a bottom layer 2 and an air layer, an air layer is set in the local area between the surface layer 1 and the bottom layer 2, and the penetrating area 31 of the perforation 3 penetrates the surface layer 1, the bottom layer 2 and the air layer.

[0037] Compared with Example 1, the difference between Examples 2-4 lies in the change of the upper fabric structure.

[0038] Example 5

[0039] This embodiment provides an ultrasonically punched shoe upper, which differs from the first embodiment in that the shoe upper body 10 is made of woven fabric, knitted fabric or non-woven fabric.

[0040] Example 6

[0041] This embodiment provides an ultrasonically punched shoe upper, which differs from the first embodiment in that the shoe upper body 10 is made of polyester, nylon, spandex or cotton.

[0042] Example 7

[0043] This embodiment provides an ultrasonically punched shoe upper, which differs from the first embodiment in that the shoe upper body 10 is single-color or multi-color.

[0044] In summary, the ultrasonic perforated shoe upper in the present invention is not limited to the material, structure, and color combination of the shoe upper, and a three-dimensional perforated structure can be formed on the corresponding shoe upper.

[0045] like Figure 2 As shown, the edge of the perforation 3 has a certain curvature, and the edge curve is arc-shaped. After punching, a fused edge hole is formed. The fused edge hole is the structure that connects the penetrating area 31 and the surface of the upper.

[0046] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
