Abstract
Description
TECHNICAL FIELD The present application relates to the material splicing and sewing technology in luggage manufacturing, which combines Chinese traditional mortise and tenon process with modern technology, covers all luggage materials and new sewing wires, and aims to build a luxury level splicing process with cultural genes, and promote the high-endization and cultural output of Chinese luggage brands. BACKGROUND Traditional luggage process has many shortcomings: in terms of materials, it is limited to a few conventional materials, and has poor adaptability to new technology materials; in terms of processing, it is difficult to guarantee the precision of small size concave-convex structure, and the precision parameters do not consider the hardness difference of materials; the sewing wire depends on traditional materials such as cotton and hemp, and has limited strength and durability. The development of 3D cutting and engraving technology solves the problem of multi-material processing, and the emergence of new artificial technology materials such as aramid fiber and graphene composite wire provides higher strength and better quality options for sewing. Internationally, brands such as Hermès rely on unique processes, and the Chinese luggage industry needs to tap the value of the mortise and tenon process, combine all materials and new wires, and create its own luxury card to achieve cultural output. INVENTION 1. Invention purpose: Provide a splicing process based on mortise and tenon concave-convex structure, covering all luggage materials and new sewing wires, solving the limitations of traditional process, inheriting culture, and helping to build Chinese luxury luggage brand. 2. Technical scheme · Concave-convex structure: composed of concave bottom 1, convex part 2, and mortise and tenon joint 3, which can be processed on any luggage material, and the shape is not limited.
[0001] · Material and processing: adapt to leather, wood, metal, carbon fiber and various new technology materials, processed by 3D cutting and engraving technology, and the precision parameters are adjusted according to the hardness characteristics of the materials (such as metal precision error ≤ ±0.1mm, wood ≤ ±0.3mm).
[0002] · Sewing and wire: can use hidden sewing dotted line 4 (inside) and exposed sewing solid line 5 (outside), and the wire can be selected from traditional materials or any high-strength artificial technology new material (such as wear-resistant polymer composite wire, high-temperature-resistant ceramic fiber wire, etc.), according to the material characteristics and use requirements to select, in order to improve the sewing strength and durability. 3. Beneficial effects · Technical level: break through the limitations of materials and wires, suitable for more scenes; no need to thin the material, simplify the process; precision adjusts with materials, splicing is more stable; new wires improve sewing quality and prolong product life.
[0003] · Cultural and brand level: taking mortise and tenon process as the cultural core, benchmarking international luxury brands, giving the product cultural connotation, helping to build Chinese luxury luggage brand, and promoting the output of Chinese traditional culture. EXPLANATION OF DRAWINGS attached Figures 1-5 Different materials (such as carbon fiber, new composite materials) and new wire (such as aramid fiber wire) are respectively shown in the splicing diagram, and the recessed bottom is marked as 1, the protruding part is marked as 2, the mortise and tenon joint is marked as 3, the hidden stitching dotted line is marked as 4, the exposed stitching solid line is marked as 5, and the technical scheme is intuitively presented. (five) specific implementation Take a new carbon fiber luggage as an example: select carbon fiber material, design appropriate concave-convex structure, process by laser cutting technology (parameters are adjusted according to the characteristics of carbon fiber), select aramid fiber wire (high-strength artificial new material) for exposed stitching solid line 5 reinforcement, so that the thickness after splicing is consistent with single-layer carbon fiber, which not only ensures the strength but also reflects the mortise and tenon cultural connotation, and helps the product to be high-end.
