Description

Technical Field

[0001] The present invention relates to a badminton ball, in particular to a badminton ball and its composite process, and belongs to the technical field of badminton and its processing methods. Background Art

[0002] Traditional badminton is composed of a ball head and a ball body combined. The ball body is made by processes such as cutting, shaping, bonding, and inserting duck feathers or goose feathers, and then fixed by winding and processed with glue.

[0003] With the development of society and the progress of industrial automation, natural duck feathers or goose feathers have several insurmountable defects: 1) Difficult to collect and limited resources, and feather pieces can only be provided by some farms and slaughterhouses; 2) Feather pieces carry follicles and cortical organic substances that need to be disinfected, otherwise they are prone to infection; 3) Cannot be stored for too long, and feather pieces are prone to mildew and deformation; 4) The weights and qualities of naturally collected feather pieces vary greatly, and they need to be selected, which is time-consuming and laborious; 5) Due to individual differences, each feather piece or ball body cannot be processed by mechanical processes, and the final inspection of the product cannot be replaced by machines; 6) Environmental protection resources are wasted, and the treatment of waste materials and compounds such as glue requires the environment to pay a price; 7) Due to the inability to unify production standards and the large error in manual inspection, the qualified rate of finished products is low; 8) All manufacturers have a large amount of manual labor and require experienced employees, so the cost is extremely high.

[0004] Artificial badminton is the trend of development. It can replace existing natural feathers, making mechanical automation operation a reality. Currently, it has been increasingly valued by production enterprises and applied by sports participants. Some brands have launched several artificial badminton balls on the market; however, there are still disadvantages: 1) Feather pieces are easy to break; 2) When hitting the ball head with gravity, the turning resistance is relatively large; 3) Feather pieces are easy to deform and explode; 4) The center of gravity is prone to deviation and the flight is unstable; 5) Excessive glue is used and the weight is not easy to control; 6) The experience is poor.

[0005] Therefore, it is particularly necessary to provide a badminton ball body with a simple and reasonable structure design, light weight, high strength, good flexibility, low environmental pollution, and good composite fastness. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art, and to provide a badminton ball body with a simple and reasonable structure design, stable and reliable, light weight, high strength, good flexibility, low environmental pollution, and good composite fastness, and its composite process.

Specific implementation mode

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention and the present invention is not limited to the following embodiments.

[0029] Embodiment.

[0030] See Figures 1 to 9 , in this embodiment, the badminton ball body includes a ball head 2, a high-density coil 3 and several groups of feather structures 1. Several groups of feather structures 1 are installed inside the ball head 2. Each group of feather structures 1 includes a feather piece 11 and a feather shaft 12. A feather piece 11 is arranged on the surface of each feather shaft 12. The feather shafts 12 are fixed to each other through a plurality of high-density coils 3. The feather pieces 11 adopt a multi-layer composite structure.

[0031] In this embodiment, the feather structure 1 has 16 pieces (the number can be selected according to the actual situation). The feather piece 11 adopts a multi-layer (2-4 layers) composite structure of foamed cotton or sprayed flannel or melt-blown cloth, which reduces the weight while increasing the strength of the feather piece.

[0032] According to the bionics principle, imitating the support structure of natural feather pieces, transverse or oblique or reticular reinforcing ribs 111 are arranged between the multi-layer composite structures. The reinforcing ribs 111 cover the main part of the feather piece 11 and can be designed to be of different thicknesses, with a slightly thicker part near the feather shaft 12.

[0033] According to the aerodynamics principle, a porous structure 112 is designed on one side of each individual feather piece 11. The porous structure is a plurality of crescent-shaped holes; it is used for the rotation and air flow exchange during the flight of the badminton, that is, it reduces the weight and makes the flight more stable; for the plurality of crescent-shaped holes, the air resistance is controllable and the service life of the feather piece is increased.

[0034] In this embodiment, the structure of the feather piece 1 can be slightly M-shaped structure 113 when viewed from the tangential cross-section, forming an angle of 0.1-3°. It is thick and heavy in the middle and light on both sides, with good flexibility and high strength, and is suitable for the staggered superposition of the feather pieces 11 at a standard angle. When viewed from the oblique cross-section, it can be a continuous M-shaped structure 113, increasing the strength and anti-bending.

[0035] In this embodiment, the feather shaft 12 is made of carbon fiber, which has the advantages of light weight, good resilience, and high strength; or it is made of aramid fiber, which has the advantages of softness and relatively good toughness.

[0036] In this embodiment, starting from the ball head 2 part, the feather shaft 12 is arranged in a structure that gradually tapers from thick to thin, so that the counterweight can be controlled within a controllable range in the later stage.

[0037] In this embodiment, the feather shaft 12 does not extend to the top of the feather vane 11, and about 3 mm of unsupported state is reserved, which can effectively prevent the passive breakage of the feather vane 11 when the badminton is hit.

[0038] In this embodiment, the side cross-section of the feather vane 11 is provided with a corrugated or serrated structure 114; this increases the bonding degree between the feather vane 1 and the feather shaft 12 and is not easily loosened.

[0039] In this embodiment, the traditional insertion of the feather shaft 12 and the ball head 2 is flat insertion, perpendicular to the insertion plane of the ball head 2, and there is still a standard outward angle with the central axis of the ball head 2. In this application, it can be inserted at an inclined angle between 0.1 - 3° with the insertion plane of the ball head 2; this method facilitates setting the center of gravity of the badminton 10 mm above the insertion plane of the feather shaft 12 and the ball head 2.

[0040] In this embodiment, the feather shaft 12 and the feather vane 11 are bonded using fixing glue, hot melting, or ultrasonic technology.

[0041] In this embodiment, the ball head 2 is made of plastic, composite cork, or other materials.

[0042] The composite process of the badminton sphere in this embodiment is as follows: (S1) One of ultrasonic composite, fixing glue bonding, or hot melting technology is used for the feather vane 11; (S2) The feather shaft 12 is made into a sheet shape or a needle shape, painted with paint, with a thickness S of 0.6 mm, a fine-edge chamfer R of 0.25 mm, a wide-edge B of 2.3 mm, and the depth H of the part inserted into the ball head 2 is about 10 mm. The part of the feather shaft 12 inside the ball head 2 is thick; (S3) The feather shaft 12 is inserted at an inclined angle with the insertion plane of the ball head 2, and the feather vanes 11 overlap each other, with an overlapping range of 1 - 3 mm; (S4) Between each feather shaft 12, they are connected into a high-density coil 3 with a line, and there are 2 or more high-density coils 3; (S5) Waterproof fixing glue is applied to the feather shaft 12, the high-density coil 3, and the insertion part of the ball head 2.

[0043] Both the badminton sphere and its composite process in this embodiment are innovative and can be applied to badminton products alone. Through the above description, those skilled in the art can already implement it.

[0044] In addition, it should be noted that for the specific embodiments described in this specification, the shapes, names, etc. of the parts and components can be different.
