Description

Technical Field

[0001] This invention relates to the field of badminton racket overlay technology, specifically to a carbon fiber badminton racket handle overlay device. Background Technology

[0002] Carbon fiber badminton rackets are high-performance sports equipment made primarily of carbon fiber composite materials. They are characterized by their light weight, high strength, and good torsional resistance, providing excellent hitting power and stability. Handle wrapping refers to the process of wrapping a special grip rubber around the handle. Its main functions are to provide athletes with a stable and comfortable grip, effectively absorb hand sweat to prevent slippage, and reduce the vibration transmitted to the arm during impact through the rubber's cushioning effect, thereby improving control and preventing sports injuries. The purpose of the wrapping device is to automate this process. It can precisely, efficiently, and consistently complete the positioning, wrapping, and fixing of the rubber, replacing the traditional inefficient manual wrapping. This ensures that the wrapping quality and tightness of each racket handle are uniform, thus significantly improving production efficiency and product yield.

[0003] In the prior art, publication number "CN221412171U" discloses a carbon fiber badminton racket handle covering device, including a carbon fiber racket body, a clamping assembly, and a material roll. The carbon fiber racket body includes a handle portion, a middle shaft, and a racket head. The clamping assembly is used to clamp and release the middle shaft. The clamping assembly is mounted on a winding plate, and the winding plate has a through hole in the middle, which is larger than the size of the racket head. A large gear is fixedly mounted on the winding plate, and the large gear is connected to a small gear through gear meshing. The small gear is connected to a drive motor, and the drive motor is mounted on a motor frame. In this utility model, a handle cleaning brush is set in the travel area of ​​the racket displacement mechanism. When the handle portion of the carbon fiber racket body is moved to the position of the handle cleaning brush, the drive motor is started to drive it to rotate, which can remove the dust adhering to the outer surface of the handle portion, prevent dust from adhering inside when the covering material is wrapped, and increase the friction force, making it less prone to loosening.

[0004] However, existing technologies still have significant shortcomings, such as: In the aforementioned devices and existing technologies, the traditional badminton racket handle wrapping relies entirely on skilled workers to manually wrap the rubber. This is not only inefficient and costly, but also results in extremely unstable wrapping quality. Uneven rubber tension and improper spacing often occur due to uneven hand strength, easily leading to defects such as wrinkles, overlaps, or excessive gaps. These defects severely affect the handle's aesthetics and grip comfort. Furthermore, manual operation makes it difficult to ensure consistent processing for each racket, resulting in inconsistent product quality and making standardized production impossible. Long-term operation can also lead to worker fatigue. Summary of the Invention

[0005] The purpose of this invention is to provide a carbon fiber badminton racket handle cover device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a carbon fiber badminton racket handle overlay device, comprising a worktable, a clamping mechanism on the top surface of the worktable, an overlay mechanism near one end of the worktable, and a mating component at the bottom of the overlay mechanism; The clamping mechanism includes clamping plates and guide grooves, and the positions and number of the guide grooves and clamping plates correspond to each other. The foreskin mechanism includes a foreskin ring, and a leather tube is connected to the inner wall of the foreskin ring; The mating assembly includes a housing, with rollers on the top of the housing and a support rod connected to the bottom of the housing.

[0007] Preferably, the guide groove is provided through the top surface of the workbench, and there are multiple sets of guide grooves. The bottom of the clamping plate is provided with a connecting plate and a bottom plate in sequence.

[0008] Preferably, the clamping plate is attached to the top surface of the workbench, and the bottom plate is attached to the bottom surface of the workbench, and the two are connected and fixed by a connecting plate.

[0009] Preferably, the connecting plate is located inside the guide groove and the two are slidably connected. A spring is installed inside the guide groove, and one end of the spring is connected to the connecting plate.

[0010] Preferably, the foreskin ring is circular, and the center of the foreskin ring coincides with the center of the racket handle during foreskin treatment.

[0011] Preferably, the inner wall of the foreskin ring is connected to a connecting seat, and the foreskin tube is located between two connecting seats.

[0012] Preferably, the foreskin ring fits into the interior of the casing and the two are movably connected. The surface of the foreskin ring is provided with a roller groove, and the roller contacts the roller groove.

[0013] Preferably, the top of the casing is fixed with a connecting bracket, and the roller is located between two connecting brackets.

[0014] Preferably, a motor is connected to one side of the top of the packaging shell, a support frame is fixed to the surface of the motor, and sprockets are respectively installed at one end of the extended roller and the rotating end of the motor, with a chain sleeved on the surface of the sprocket.

[0015] Preferably, a connecting frame is bolted to the bottom surface of the workbench, and a lead screw and a limiting rod are respectively installed in the connecting frame. A movable plate is sleeved on the surface of the lead screw and the limiting rod, and the movable plate is connected and fixed to the bearing connecting rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Utilizing multiple spring-driven clamping plates distributed around the center of the worktable, the racket frame moves synchronously radially along the guide groove and automatically centers and clamps when placed in. By applying moderate elastic force evenly through multiple contact points, a clamping mechanism is formed, which can firmly fix rackets of different sizes and types, providing a stable foundation for subsequent precision overlay. It also completely avoids deformation or surface damage to the precious carbon fiber frame caused by excessive clamping force or stress concentration at a single point, perfectly balancing broad compatibility, ease of operation, and product protection.

[0017] 2. The friction rollers are driven by a motor via a sprocket system, causing the rubber wrapping ring to rotate smoothly. At the same time, the linear movement is precisely controlled by a screw mechanism. The combination of these two movements achieves spiral winding, replacing the manual winding that relies entirely on the skill of workers. The mechanical precision ensures that the rubber has constant tension and uniform pitch during the winding process, fundamentally eliminating defects such as rubber overlap, wrinkles, or uneven gaps. The final product has a perfectly smooth and beautiful handle with a consistent grip, greatly improving production efficiency and product standardization. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 The present invention provides a technical solution: Example 1: A carbon fiber badminton racket handle wrapping device: It includes a worktable 1, a clamping mechanism 2 on the top surface of the worktable 1, a wrapping mechanism 3 near one end of the worktable 1, and a mating component 4 at the bottom of the wrapping mechanism 3. The device is mainly composed of the clamping mechanism 2, the wrapping mechanism 3, and the mating component 4. Its main function is to evenly wrap the rubber around the handle of the badminton racket, thereby improving the user experience and preventing slippage. The clamping mechanism 2 includes clamping plates 21 and guide grooves 22. The positions and numbers of the guide grooves 22 and clamping plates 21 correspond to each other. The guide grooves 22 are opened through the top surface of the workbench 1, and there are multiple sets of guide grooves 22. The bottom of the clamping plates 21 is provided with connecting plates 25 and bottom plates 24 in sequence. The clamping plates 21 are attached to the top surface of the workbench 1, and the bottom plates 24 are attached to the bottom surface of the workbench 1. The two are connected and fixed by the connecting plates 25. The connecting plates 25 are located inside the guide grooves 22, and the two are slidably connected. A spring 23 is installed inside the guide grooves 22, and one end of the spring 23 is connected to the connecting plates 25. The clamping mechanism 2 is located on the top surface of the workbench 1 and is mainly used to clamp and fix the racket frame, thereby facilitating the subsequent overlay process. To further explain, the clamping mechanism 2 uses multiple clamping plates 21 to clamp the racket frame. The clamping plates 21 are located on the top surface of the workbench 1. Located on the top surface of workbench 1 and distributed around the center of workbench 1, the bottom of clamping plate 21 includes a base plate 24 that fits against the bottom surface of workbench 1. A connecting plate 25 is fixed between the base plate 24 and clamping plate 21. The connecting plate 25 is mainly located in the guide groove 22 opened on the top surface of workbench 1. There are four sets of guide grooves 22, which correspond to the number and position of clamping plates 21. The spring 23 in the guide groove 22 is directly connected and fixed to the connecting plate 25. When it is necessary to process the handle of the racket, the racket frame is simply inserted between multiple clamping plates 21. The clamping plates 21 are displaced along the guide groove 22 by the elastic force of the spring 23, thereby ensuring that the racket frame is placed between multiple clamping plates 21. The spring 23 pushes the clamping plates 21 until the clamping plates 21 abut against the surface of the racket frame, thereby limiting and fixing the racket.

[0022] Multiple springs 23 are used, and multiple springs 23 pop out simultaneously to clamp the racket frame with the clamping plate 21. Therefore, it is not advisable to choose springs 23 with high elasticity. Normal and suitable springs 23 can be selected to avoid excessive elasticity that may squeeze and deform the racket frame. Utilizing the coordinated action of multiple clamping plates 21 driven by springs 23 distributed around the worktable 1, when the racket frame is placed in, the clamping plates 21 move radially synchronously along the guide groove 22 under the push of the spring 23's rebound force, thereby gently and steadily wrapping the racket frame and automatically centering and clamping it. By selecting springs 23 with moderate rather than excessive elasticity and applying force evenly at multiple points, a safe and reliable flexible clamping of the carbon fiber racket frame is achieved. This provides sufficient stability for subsequent overlay processing and completely avoids the risk of the precious racket frame being squeezed and deformed or its surface damaged due to excessive local stress. It perfectly balances the stability of clamping and the protection of the product, and can be adapted to rackets of different sizes or types, such as badminton rackets and tennis rackets.

[0023] The forging mechanism 3 includes a forging ring 31, with a rubber sleeve 33 connected to its inner wall. The forging ring 31 is circular, and its center coincides with the center of the racket handle during forging. A connecting seat 32 is connected to the inner wall of the forging ring 31, and the rubber sleeve 33 is located between two connecting seats 32. The forging mechanism 3 uses the forging ring 31 to rotate along the surface of the racket handle while simultaneously moving linearly to evenly wrap the rubber around the handle surface. Specifically, the forging ring 31 is circular with a through-hole in the middle for fitting onto the handle surface. The outer surface of the rubber sleeve 33 is the rubber to be wrapped, and it is connected to the forging ring 31 via the connecting seats 32. When the forging ring 31... The wrapping process can be achieved by rotating and moving. The wrapping ring 31 has a circular hollow structure. Its primary purpose is to accurately fit onto the outside of the racket handle, providing a concentric reference for the subsequent winding action. The rubber roll is fixed to the inner wall of the wrapping ring 31 through the connecting seat 32. This position ensures that the rubber supply source and the winding execution component are tightly integrated into a whole. When the wrapping ring 31 performs a compound motion of both rotation and movement, it can always use the handle axis as a reference and smoothly wind the rubber from the outer rubber sleeve 33 into the handle surface with constant tension and precise pitch, thereby achieving uniform, efficient and high-quality automated wrapping.

[0024] Example 2: Based on Embodiment 1, the cooperating component 4 includes a housing 41, with a roller 42 on the top of the housing 41 and a supporting connecting rod 45 connected to the bottom of the housing 41. A skin ring 31 engages with the inside of the housing 41 and the two are movably connected. A groove 44 is formed on the surface of the skin ring 31, and the roller 42 contacts the groove 44. A connecting bracket 43 is fixed to the top of the housing 41, and the roller 42 is located between two connecting brackets 43. A motor 5 is connected to one side of the top of the housing 41, and a surface of the motor 5 is fixed with... The support frame 51 has sprockets 6 installed at one end of the extended roller 42 and the rotating end of the motor 5, respectively. A chain 7 is fitted onto the surface of the sprocket 6. The mating assembly 4 mainly refers to the rotating and moving parts of the sheath ring 31. The sheath ring 31 is located inside the sheath shell 41 and can rotate within it. The sheath shell 41 also provides a limiting mounting for it. The connecting bracket 43 connects the roller 42 to the sheath shell 41. The roller 42 is located at the groove 44 on the surface of the sheath ring 31. The two work together to ensure... When roller 42 rotates, it can rotate together with the sheath ring 31 under contact. Specifically, roller 42 is connected to the bearing of connecting bracket 43, and its connecting end extends to the outside. At this end, a sprocket 6 is installed at the rotating end of motor 5. A chain 7 is sleeved with the sprocket 6. When motor 5 is working, the transmission of sprocket 6 and chain 7 can make roller 42 rotate, thereby driving sheath ring 31. To ensure that roller 42 can drive sheath ring 31 to rotate normally, friction is added to the surface of roller 42. To increase friction, the motor 5 drives the sprocket 6 and chain 7 to efficiently transmit power to the roller 42 that contacts the wrapping ring 31. By utilizing the principle of friction transmission, the wrapping ring 31 rotates smoothly, ensuring that the tape unrolled from the rubber roll is always subjected to uniform and consistent tension during the winding process. It can also perform precise spiral winding according to the preset pitch, thus completely avoiding problems such as rubber wrinkling, overlapping, or uneven gaps that often occur in manual winding. This ensures the smoothness and aesthetics of the wrapping surface and the consistency of the grip.

[0025] A connecting frame 47 is bolted to the bottom surface of the workbench 1. A lead screw 48 and a limiting rod 49 are respectively installed inside the connecting frame 47. A movable plate 46 is sleeved on the surface of the lead screw 48 and the limiting rod 49, and the movable plate 46 is connected and fixed to the bearing connecting rod 45. The wrapping shell 41 is connected to the movable plate 46 through the bearing connecting rod 45. One end of the bearing connecting rod 45 effectively provides good support and load-bearing capacity for the wrapping shell 41. When the movable plate 46 moves linearly along the surface of the limiting rod 49 as the lead screw 48 moves in the connecting frame 47, the wrapping shell 41 can drive the outer sheath ring 31 to move linearly. The movement does not affect the rotation of the wrapping ring 31. It can rotate and move simultaneously to complete uniform winding. The moving plate 46 is driven by the screw 48 and nut mechanism, which drives the entire wrapping shell 41 and the wrapping ring 31 to make precise linear movements along the limit rod 49. It can precisely coordinate with the rotational movement of the wrapping ring 31. By controlling the ratio of the linear movement speed to the rotational speed through the program, the winding spacing of each turn of rubber is precisely set, realizing fully automatic and uniform speed wrapping from one end of the handle to the other without manual intervention, which greatly improves the accuracy, efficiency and consistency of product quality.

[0026] Working Principle: The device mainly consists of a clamping mechanism 2, a wrapping mechanism 3, and a cooperating component 4. It is primarily used to evenly wrap the rubber around the handle of the badminton racket, improving the user experience and preventing slippage. The clamping mechanism 2, located on the top surface of the workbench 1, is mainly used to clamp and fix the racket frame, facilitating subsequent wrapping. Specifically, the clamping mechanism 2 utilizes multiple clamping plates 21 to clamp the racket frame. These clamping plates 21 are located on the top surface of the workbench 1 and distributed around the center of the workbench 1. The bottom includes a base plate 24 that fits against the bottom surface of the workbench 1. A connecting plate 25 is fixed between the base plate 24 and the clamping plate 21. The connecting plate 25 is mainly located in the guide groove 22 opened on the top surface of the workbench 1. There are four sets of guide grooves 22, which correspond to the number and position of the clamping plates 21. The springs 23 in the guide grooves 22 are directly connected and fixed to the connecting plate 25. When it is necessary to process the handle of the racket with a leather wrap, the racket frame is simply inserted between multiple clamping plates 21. The clamping plates 21 are displaced along the guide grooves 22 by the elastic force of the springs 23, thereby ensuring that multiple racket frames can be inserted. Between the clamping plates 21, the spring 23 pushes the clamping plates 21 until they abut against the surface of the racket frame, thus fixing the racket in place. Multiple springs 23 are used, with multiple springs 23 simultaneously springing out to clamp the racket frame. Therefore, avoid choosing springs 23 with excessive elasticity; a normal and suitable spring 23 is sufficient. Excessive elasticity can cause deformation of the racket frame. The multiple clamping plates 21, distributed around the worktable 1 and driven by springs 23, work together. When the racket frame is placed in, the clamping plates 21 are pushed by the spring 23's rebound force. The lower guide groove 22 moves radially in sync, gently and firmly wrapping around the racket frame and automatically centering and clamping it. By selecting a spring 23 with moderate rather than excessive elasticity and applying force evenly at multiple points, a safe and reliable flexible clamping of the carbon fiber racket frame is achieved. This provides sufficient stability for subsequent overlay processing while completely avoiding the risk of the precious racket frame being squeezed and deformed or its surface damaged due to excessive local stress. It perfectly balances the stability of the clamping and the protection of the product, and can be adapted to rackets of different sizes or types, such as badminton and tennis rackets. The wrapping mechanism 3 utilizes a wrapping ring 31 that rotates along the surface of the racket handle while simultaneously moving linearly to evenly wrap the rubber around the handle surface. Specifically, the wrapping ring 31 is circular with a through-hole in the center, used to fit over the handle surface. The outer surface of the rubber sleeve 33 is the surface of the rubber to be wrapped, and it is connected to the wrapping ring 31 via a connecting seat 32. When the wrapping ring 31 rotates and moves, the wrapping process is achieved. The wrapping ring 31 has a circular hollow structure, the primary purpose of which is to accurately fit over the outside of the racket handle, providing a concentric reference for the subsequent wrapping action. The rubber roll is fixed to the inner wall of the wrapping ring 31 via the connecting seat 32. This positioning ensures that the rubber supply source and the wrapping execution component are tightly integrated into a whole, so that when the wrapping ring 31 performs a combined rotational and moving motion, it can always use the handle axis as a reference, smoothly wrapping the rubber from the outer rubber sleeve 33 with constant tension and precise pitch spirally around the handle surface, thereby achieving uniform, efficient, and high-quality automated wrapping.

[0027] The cooperating component 4 is mainly a collective term for the rotating and moving parts of the foreskin ring 31. The foreskin ring 31 is located inside the enclosure 41 and can rotate within the enclosure 41. At the same time, the enclosure 41 can be used to limit its installation. The connecting bracket 43 connects the roller 42 to the enclosure 41. The roller 42 is located at the groove 44 on the surface of the foreskin ring 31. The two cooperate with each other to ensure that when the roller 42 rotates, it can rotate together with the foreskin ring 31 while in contact with the roller 42.

[0028] Specifically, roller 42 is connected to the connecting bracket 43 by a bearing, with its connecting end extending to the outside. At this end, a sprocket 6 is installed at the rotating end of the motor 5, and a chain 7 is sleeved with the sprocket 6. When the motor 5 is working, the transmission of the sprocket 6 and the chain 7 can make the roller 42 rotate, thereby driving the sheath ring 31. To ensure that the roller 42 can drive the sheath ring 31 to rotate normally, friction is added to the surface of the roller 42 to increase the friction force. The motor 5 drives the sprocket 6 and the chain 7 to efficiently transmit power to the roller 42 that is in contact with the sheath ring 31. The friction transmission principle drives the sheath ring 31 to rotate smoothly, which can ensure that the tape unrolled from the rubber roll is always subjected to uniform and consistent tension during the winding process, and can be precisely wound in a spiral according to the preset pitch. This completely avoids the problems of rubber wrinkling, overlapping or uneven gaps that often occur in manual winding, and ensures the flatness and beauty of the sheath surface and the consistency of the grip.

[0029] The wrapping shell 41 is connected to the moving plate 46 via the supporting connecting rod 45. One end of the supporting connecting rod 45 effectively provides good support and load-bearing capacity for the wrapping shell 41. When the moving plate 46 moves linearly along the surface of the limiting rod 49 with the movement of the lead screw 48 in the connecting frame 47, the wrapping shell 41 can drive the wrapping ring 31 to move linearly without affecting the rotation of the wrapping ring 31. It can rotate and move simultaneously to complete uniform winding. The moving plate 46 is driven by the lead screw 48 nut mechanism, which drives the entire wrapping shell 41 and the wrapping ring 31 to make precise linear movements along the limiting rod 49. It can precisely match the rotational movement of the wrapping ring 31. By controlling the ratio of the linear movement speed to the rotational speed through the program, the winding spacing of each turn of rubber is precisely set, realizing fully automatic and uniform speed wrapping from one end of the handle to the other without manual intervention, which greatly improves the winding accuracy, efficiency and product quality consistency.

[0030] First, the racket frame is placed in the clamping mechanism 2 on the top surface of the workbench 1. Multiple clamping plates 21 move radially synchronously along the guide groove 22 under the action of moderate spring force 23, automatically centering and gently clamping the racket frame, providing a stable reference for subsequent steps. Then, the equipment is started, and the cooperating component 4 begins to work. The motor 5 drives the roller 42 through the sprocket 6 and chain 7 to rotate the forging ring 31 inside the wrapping shell 41. At the same time, the moving plate 46 moves precisely in a straight line along the limiting rod 49 under the drive of the lead screw 48. The combination of these two movements causes the rubber roll connected to the forging ring 31 to be wound evenly and smoothly in a spiral from one end of the handle to the other end with constant tension and preset pitch. The whole process does not require manual intervention and automatically completes high-quality forging.
