Description

Technical Field

[0001] The invention relates to a method for making a badminton, in particular to a method for making a single simulated feather and a method for making a badminton using the feather. Background Art

[0002] In badminton, shuttlecocks are a major consumable item. Traditional badminton production methods primarily involve manually plucking and screening feathers, sorting them by quality, growth time, and direction, measuring the feathers with a camber and curvature meter to ensure uniform curvature and arch, and cleaning, disinfecting, drying, cutting, and dyeing, all of which require extensive processing steps and high costs.

[0003] Because the raw materials are natural goose and duck feathers, with goose feathers being the highest quality, natural badmintons offer a pleasant feel, but are expensive and not durable. Only four feathers from a goose or duck can be used to make a badminton, while a shuttlecock requires 16 feathers. Natural goose or duck feathers are in short supply. During the production process, each mid-range shuttlecock costs around 18 yuan, and each low-end shuttlecock costs around 8 yuan. Furthermore, natural goose or duck feather shuttlecocks have a short lifespan, with feathers easily curling and breaking. Under normal circumstances, a shuttlecock will be discarded after an average of half an hour of play.

[0004] Artificial shuttlecocks currently use plastic for their vanes and crowns, resulting in prices as low as 3-5 yuan per shuttlecock. However, the vanes and shafts are typically made of plastic, resulting in limited simulation and a poor playing feel. These shuttlecocks are typically bonded together using processes such as gluing and hot pressing, which can cause the joints to break apart when struck, shortening the lifespan of the artificial shuttlecocks. Chinese patent application number 201010291489.4 discloses a method for producing shuttlecock vanes. While this method improves durability, it is complex, still uses viscose, and offers limited simulation, failing to match the quality of natural shuttlecocks. Consequently, no such shuttlecocks are currently commercially available. Summary of the Invention

[0005] The technical problem to be solved by the present application is to provide a method for producing a single simulated feather with good simulation effect, a hitting feel close to that of a natural badminton, a firm connection, high durability, simple process and low price. At the same time, the present invention also provides a method for producing a badminton using the feather.

[0006] In order to solve the above technical problems, the present invention adopts a method for making a single artificial feather, which is characterized by comprising the following steps:

[0007] Cutting a plurality of feathers with outer edges consistent with the shape of feathers used in badminton made of natural feathers from a flexible sheet material to form flexible feathers;

[0008] A row of through holes is formed longitudinally in the middle of each of the flexible vanes;

[0009] Meanwhile, prepare the feather rod injection mold;

[0010] The flexible vanes are laid in a mold, and a composite material of engineering plastic and glass fiber is injection-molded into the mold to form a feather rod. During the injection molding of the feather rod, the composite material is connected to the flexible vanes through the through holes, and the fabric vanes are integrally clamped in the feather rod, with the flexible vanes firmly connected to both sides of the feather rod. The mold is then demolded to obtain a single simulated feather.

[0011] In a further technical solution, the injection mold is a multi-cavity mold, and a piece of the fabric vane is laid in each cavity, and a corresponding feather rod is injection-molded.

[0012] The flexible sheet is made of a fabric made of polymer fiber or a film made of a composite material.

[0013] The flexible vanes are more preferably fabric vanes.

[0014] The fabric is further preferably woven from transverse fibers and longitudinal fibers; the longitudinal fibers are thicker than the transverse fibers, and the longitudinal texture of the fabric vanes is more obvious than the transverse texture; the longitudinal texture is consistent with the longitudinal direction of the feather shaft.

[0015] The longitudinal texture deviates from the longitudinal direction of the feather shaft and extends obliquely outward, consistent with the distribution of barbs of natural feathers.

[0016] The feather rod is in the shape of a continuous rod with one end thick and the other end thin. The thick end is the root of the feather rod, and the fabric vane is connected to the thin part. During injection molding, a groove similar to a natural feather rod is formed on the feather rod.

[0017] The weight of a single artificial feather is equivalent to that of a natural feather cut and used for making badminton.

[0018] The present invention also provides a method for making a badminton using a single artificial feather obtained by the above method, which is characterized by mainly comprising the following steps:

[0019] The roots of the feather shafts of the plurality of single simulated feathers are firmly inserted into the plurality of connecting holes spaced apart on the ball head in a corresponding manner; at this time, all the single simulated feathers are spirally and radially distributed, and the flexible vanes of adjacent single simulated feathers partially overlap;

[0020] Use baling wire to wrap around all the feather rods and connect them together.

[0021] A further technical solution is that each badminton is made of 16 single simulated feathers.

[0022] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in the following aspects:

[0023] The present invention uses a flexible thin sheet material with good flexibility. Compared with the existing artificial single-piece or injection-molded mesh shuttlecocks, the single simulated feather obtained by the present invention is closer to a real feather and less stiff. When made into a shuttlecock, it flies smoothly and stably, with accurate landing points, and can achieve a hitting feel similar to that of a natural shuttlecock. The feather is durable, and under normal use, a shuttlecock can last for more than a week. It is also inexpensive and easy to produce. The feather shaft is injection-molded into an integral piece through a through hole in the feather, and the feather is integrally clamped within the feather shaft. The feather is firmly connected to both sides of the feather shaft, creating a very stable connection, further improving durability. The production process is simple and convenient. In a further technical solution, simulated fabric vanes are cut from polymer fiber fabric, achieving excellent simulation results. When the longitudinal texture of the fabric vane is more pronounced than the transverse texture, the longitudinal texture aligns with the longitudinal direction of the feather shaft, which more closely resembles the barb orientation of a natural feather, further resembling the feel of a real badminton. When the longitudinal texture deviates from the longitudinal direction of the feather shaft and extends obliquely outward, aligning with the barb orientation of a natural feather, it further resembles a real badminton. Using a single simulated feather obtained by the above method to make a badminton, the simulation results are excellent. Repeated trials and verification by the inventors of samples have shown that the feel of the shuttlecock closely resembles that of a natural feather, with a secure connection and high durability. The process is simple and the price is low, significantly reducing the cost of playing badminton for badminton enthusiasts. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions of the preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] In order to make Figure 1-4 、 Figure 7 The single artificial feather 10 shown, and further made as Figure 5-6 、 Figure 8 The manufacturing method of the present invention mainly includes the following steps.

[0035] like Figure 7 As shown, the present invention preferably uses a fabric made of polymer fibers. The fabric is woven from transverse and longitudinal fibers, resulting in excellent flexibility. The longitudinal fibers of the artificial feather simulation fabric are thicker, resulting in a more pronounced longitudinal texture than the transverse texture. The longitudinal texture aligns with the longitudinal direction of the feather shaft 12, which more closely resembles the barb orientation of a natural feather, further resembling the feel of a real badminton shuttlecock. Such "vertical-grained" fabric vanes are relatively easy to produce. When the longitudinal texture deviates from the longitudinal direction of the feather shaft and extends obliquely outward, aligning with the barb orientation of a natural feather, this further resembles a natural feather.

[0036] The fabric is cut into a plurality of fabric vanes 11, the outer edges of which are consistent with the shape of the vanes used in badminton made of natural feathers; and a row of through holes 111 are formed longitudinally in the middle of each fabric vane 11; the through holes can be formed by laser cutting or punching die cutting according to the existing technology.

[0037] At the same time, a feather shaft injection mold is prepared. The mold is designed and manufactured according to conventional techniques. The mold cavity corresponds to the shape and size of the feather shaft 12, and a position is reserved for the fabric vane 11. For higher production efficiency, the injection mold is preferably a single mold with multiple cavities, with each cavity accommodating one fabric vane 11 and correspondingly injecting one feather shaft 12. To meet the needs of simulation, the feather shaft 12 is a continuous rod with one thick end and one thin end. The thick end is the root 123 of the feather shaft, and the fabric vane 11 is connected to the thin end. The feather shaft is also provided with a groove 122 similar to that of a real feather shaft.

[0038] The fabric vane 11 is laid in a mold, and a composite material of engineering plastic and glass fiber is injected into the mold to form a feather rod 12; when the feather rod 12 is injected, the composite material passes through the through hole 111 and is connected to the fabric vane 11 as a whole, and the fabric vane 11 is clamped in the feather rod 12 as a whole, and the fabric vane 11 is firmly connected to both sides of the feather rod 12. Figure 4 From the top, it can be seen that there is a feather passage hole 121 in the feather rod 12.

[0039] Open the mold, demould, and obtain a single artificial feather 10 from each mold cavity. Figure 1 It is comparable in weight to natural feathers cut for shuttlecocks.

[0040] Prepare the ball head 20 and the binding tape 30 according to the existing technology, which can be conventional products available on the market. The feather stem roots 123 of several single artificial feathers 10 are firmly inserted into the plurality of connecting holes 21 spaced apart on the ball head 20 one by one. At this time, all the single artificial feathers 10 are arranged in a spiral and radial pattern, and the fabric vanes 11 of adjacent single artificial feathers 10 partially overlap. Use the binding tape 30 to surround and connect all the feather stems 12, and the feather is ready. Figure 5 and 6 Each badminton of this embodiment is made of 16 single artificial feathers 10.

[0041] In addition, the present invention can also use thin films made of other composite materials to simulate vanes, which are flexible, light and thin, and can be made into flexible vanes, such as Figure 3 As shown, the feather rod is then injected, which is the same as the above structure. Figure 1 As shown, the two are firmly connected as one.
