Description

Technical Field

[0001] This utility model relates to the field of footwear and apparel technology, specifically to a 3D printed water embroidery shoe upper. Background Technology

[0002] Shoes are a type of clothing accessory whose function is to protect and cover the user's feet. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, while the upper is the upper part that is located on top of the sole. The upper covers the user's foot and connects with the sole to fix the sole to the user's foot, preventing the sole from falling off. The design of the upper can effectively improve the integration of the shoe and foot, and make the shoe more protective of the foot and provide better warmth.

[0003] Embroidered uppers are a type of shoe upper made by weaving multiple yarns alternately. Embroidered uppers are very breathable, and the material is tough and has a stronger resistance to breakage than ordinary uppers. They have good coverage and durability, and have a long service life and are not easily damaged.

[0004] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: the production of existing embroidered shoe uppers requires different yarns to be wrapped and woven together, which requires many steps to weave and produce the finished product. If more vivid colors are required, additional colored yarn weaving steps are needed, making it even more cumbersome and complicated. As the finished embroidered shoe upper contains many layers of different yarns, its extensibility is poor and its fit to the foot is generally poor, which can easily cause discomfort to the feet. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a 3D-printed water embroidery shoe upper that is simple to process, fast, and has good elasticity and fit.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a 3D printed water embroidery shoe upper, comprising a 3D printed shoe upper and an integrally formed water embroidery pattern strip on the upper surface of the 3D printed shoe upper, wherein the 3D printed shoe upper is made of thermoplastic polyurethane material by 3D printing, and the water embroidery pattern strip is made of thermoplastic polyurethane material by 3D printing.

[0007] A further improvement is that the edge of the 3D printed shoe upper is integrally molded with a reinforcing layer.

[0008] A further improvement is that the 3D printed shoe upper includes several elastic printed blocks with interlocking edges and an elastic upper surface layer integrally formed on the upper surface of the elastic printed blocks.

[0009] A further improvement is that the bottom surface of the elastic printing block is also provided with an elastic lower surface layer.

[0010] A further improvement is that the bottom surface of the elastic lower surface layer is integrally formed with several friction grooves.

[0011] A further improvement is that the elastic upper surface layer is provided with several vent holes.

[0012] A further improvement is that the elastic printed block includes a core and an X-shaped elastic frame disposed on the outer wall of the core.

[0013] A further improvement is that an elastic sheet is provided between the ends of the elastic frame.

[0014] The beneficial effects of this utility model after adopting the above technical solution are as follows: This utility model forms a 3D printed shoe upper through 3D printing and forms water embroidery patterns on the 3D printed shoe upper, thereby achieving the same texture and aesthetics as water embroidery shoe uppers. It does not require precise and complex multi-layer yarn winding, weaving and stacking, and the processing speed is fast and the processing efficiency is high. At the same time, it is made of thermoplastic polyurethane material for 3D printing manufacturing, which has a lower number of layers compared with traditional water embroidery shoe uppers. At the same time, the material has high elasticity, thus having good extensibility and better fit to the foot. Attached Figure Description

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a 3D printed water embroidery shoe upper, including a 3D printed shoe upper 1 and an integrally formed water embroidery pattern strip 2 on the upper surface of the 3D printed shoe upper 1. The 3D printed shoe upper 1 includes a plurality of elastic printed blocks 11 with their edges interlocked and an elastic upper surface layer 12 integrally formed on the upper surface of the elastic printed blocks 11. The elastic printed blocks 11 include a core 111 and an X-shaped elastic frame 112 disposed on the outer wall of the core 111. The 3D printed shoe upper 1 is made of thermoplastic polyurethane material by 3D printing, and the water embroidery pattern strip 2 is made of thermoplastic polyurethane material by 3D printing. In use, the thermoplastic polyurethane material is printed into an X-shaped elastic frame 112 by a 3D printer. The structure is formed by bonding multiple elastic frames 112 together to form a 3D printed shoe upper 1. Then, the upper surface of the multiple elastic frames 112 is printed with thermoplastic polyurethane material to form an elastic upper surface layer 12. Subsequently, water embroidery pattern stripes 2 are printed on the elastic upper surface layer 12 with thermoplastic polyurethane material, thereby achieving the same texture and aesthetics as water embroidery shoe uppers. It does not require precise and complex multi-layer yarn winding and stacking, and the processing speed is fast and the processing efficiency is high. At the same time, the elastic frames 112 are manufactured by 3D printing with thermoplastic polyurethane material. A core 111 is provided at the center of the intersection. When subjected to lateral stretching, it can fully deform and has good elasticity. Compared with traditional water embroidery shoe uppers, it has fewer layers and higher elasticity, thus having good extensibility and better fit to the foot.

[0021] The 3D printed shoe upper 1 has an integrally formed reinforcing layer 3 at the edge, which helps to improve the strength of the edge of the 3D printed shoe upper 1 and prevents cracking and damage from the edge.

[0022] The bottom surface of the elastic printed block 11 is also provided with an elastic lower surface layer 13, which helps to improve the softness when in contact with the foot and prevents the foot from directly contacting the bottom of the elastic frame 112 and causing a foreign body sensation.

[0023] The bottom surface of the elastic lower surface layer 13 is integrally formed with several friction grooves 14, which helps to increase the friction when in contact with the foot and prevent the foot from slipping inside the shoe upper, thus affecting the fit.

[0024] The elastic upper surface layer 12 is provided with a plurality of air vents 15, which helps to improve air permeability;

[0025] The elastic frame 112 is provided with elastic thin sheets 113 between its ends, which helps to improve the tensile strength of the elastic frame 112. While ensuring a certain degree of extensibility, it also has a certain support strength to prevent excessive deformation and loss of foot protection when pushing off the ground laterally.

[0026] The working principle of this utility model is as follows: When using this utility model, thermoplastic polyurethane material is printed into an X-shaped elastic frame 112 structure using a 3D printer. Multiple elastic frames 112 are bonded together by their side edges to form a 3D printed shoe upper 1. Subsequently, the upper surface of multiple elastic frames 112 is printed with thermoplastic polyurethane material to form an elastic upper surface layer 12. Then, water embroidery pattern stripes 2 are printed on the elastic upper surface layer 12 with thermoplastic polyurethane material, thereby achieving the same texture and aesthetics as water embroidery shoe uppers. It does not require precise and complex multi-layer yarn winding and stacking, and the processing speed is fast and the processing efficiency is high. At the same time, the elastic frame 112 is manufactured by 3D printing with thermoplastic polyurethane material. A core 111 is provided at the center of the intersection. When subjected to lateral stretching, it can fully deform and has good elasticity. Compared with traditional water embroidery shoe uppers, it has fewer layers and higher elasticity, thus having good extensibility and better fit to the foot.
