Badminton racket carbon fiber middle tube curling forming machine and forming process thereof

Abstract

The present application belongs to the technical field of carbon fiber tube forming, and particularly relates to a badminton racket carbon fiber tube curling forming machine and a forming process thereof, which comprises a tube winding machine, a rotator and a film sleeve assembly. The rotator is installed on one side of the tube winding machine, and the film sleeve assembly is installed on the side of the rotator away from the tube winding machine. Four mold tubes are equidistantly arranged on the rotating end of the rotator. The mold tubes are rotationally connected to the rotating end of the rotator. A lifting groove is formed in the rotating end of the rotator corresponding to the position of the mold tube. The mold tube is provided with a rotating disc arranged in the lifting groove. The badminton racket carbon fiber tube curling forming machine winds the film on the mold tube through the film sleeve assembly, then sticks the carbon fiber layer, and then transmits the carbon fiber tube to the tube winding machine for curling to form the carbon fiber tube. Since the carbon fiber layer is stuck on the film and is not directly connected to the mold tube, the carbon fiber tube can be taken off by directly taking off the film, the mold tube can be easily taken out without affecting the carbon fiber tube, and the quality of the carbon fiber tube is ensured.

Description

Technical Field

[0001] This invention belongs to the field of carbon fiber tube forming technology, specifically relating to a badminton racket carbon fiber tube coil forming machine and its forming process. Background Technology

[0002] With the popularization of fitness for all, badminton has gradually become a popular sport among men, women, and children of all ages. The structure of existing badminton rackets generally includes a head frame, a shaft, and a handle. The head frame is approximately elliptical, and the net strings are strung on the head frame to serve as the hitting surface. The shaft is located between the head frame and the handle to connect the two. The shaft is a hollow cylindrical tube or a hollow conical tube and is made of carbon fiber.

[0003] The existing carbon fiber tubes for badminton rackets are usually made by first gluing the carbon fiber layer onto a mold tube, and then using a tube rolling machine to roll the carbon fiber layer onto the mold tube to form a carbon fiber tube. Because the carbon fiber layer is glued on first, the tube needs to be pulled out with force using tools when demolding it. If you are not careful during the pulling process, the carbon fiber tube will be affected and the quality will be defective. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a badminton racket carbon fiber tube coiling and forming machine and its forming process, which can easily remove the mold tube without affecting the carbon fiber tube and ensure the quality of the carbon fiber tube.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a badminton racket carbon fiber tube coiling and forming machine, including a tube coiling machine, a rotating device, and a film sleeve assembly. The rotating device is installed on one side of the tube coiling machine, and the film sleeve assembly is installed on the side of the rotating device away from the tube coiling machine. Four mold tubes are equidistantly arranged on the rotating end of the rotating device. The mold tubes are rotatably connected to the rotating end of the rotating device. A lifting groove is opened on the rotating end of the rotating device corresponding to the position of the mold tube. The mold tube is provided with a rotating disk placed in the lifting groove. Elastic elements are respectively installed at the upper and lower ends of the lifting groove, and the rotating disk is placed between two elastic elements.

[0006] A threaded rod is rotatably mounted inside the mold tube, and a rotary motor is installed inside the mold tube to drive the threaded rod to rotate. Multiple sliding nuts are rotatably fitted on the threaded rod. The sliding nuts are moved and placed inside the mold tube. First wedge blocks are equidistantly arranged on the sliding nuts along the axis of the threaded rod. The mold tube has sliding grooves for the first wedge blocks to slide. Four support plates are provided outside the mold tube. The support plates are connected to the mold tube by springs. Second wedge blocks that cooperate with the first wedge blocks are provided on the support plates at positions corresponding to the sliding grooves.

[0007] The tube rolling machine includes a worktable, a rolling plate, and a lifting platform. The rolling plate is movably mounted on the worktable, and a drive cylinder for moving the rolling plate is provided on the worktable. The lifting platform is mounted on the worktable, and the lifting plate of the lifting platform is positioned above the rolling plate.

[0008] The rotating device includes a mounting plate, a lifting device, and a rotating motor. The mounting plate is installed on one side of the tube rolling machine, the lifting device is installed on the mounting plate, the rotating motor is installed on the lifting end of the lifting device, and the four mold tubes are installed equidistantly on the rotating end of the rotating motor.

[0009] The mounting plate has a carbon fiber placement platform installed on one side of the elevator.

[0010] The carbon fiber placement platform is provided with multiple adsorption holes evenly distributed. The carbon fiber placement platform is provided with a vacuum adsorption machine that communicates with the multiple adsorption holes. A support frame is installed on the mounting plate. A movable frame is installed above the carbon fiber placement platform on the support frame. A lifting cylinder is installed on the movable frame. The lifting end of the lifting cylinder is set towards the carbon fiber placement platform. A swing gripper is installed on the lifting end of the lifting cylinder.

[0011] The swing gripper includes a swing motor, a rough panel, and a vacuum suction component. The swing motor is mounted on the lifting end of the lifting cylinder, the rough panel is mounted on the swing end of the swing motor, the rough surface of the rough panel faces the carbon fiber placement platform, and the vacuum suction component is mounted on one side of the rough panel.

[0012] The membrane assembly includes a membrane frame, a lifting gripper, a horizontal moving seat, a lifting gripper, and a blower. The membrane frame is located on one side of the rotator. The lifting gripper is mounted on the membrane frame. The horizontal moving seat is movably mounted on top of the lifting gripper, and the lifting gripper is equipped with a screw system for driving the horizontal moving seat. The lifting gripper and the blower are both mounted on the horizontal moving seat, and the air outlet of the blower faces the rotator.

[0013] The membrane frame is provided with a membrane holding groove, the bottom of the membrane holding groove is provided with a lifting device, the opening of the membrane holding groove is provided with a pressure block, and a cylindrical membrane is placed between the lifting device and the pressure block.

[0014] The molding process of carbon fiber shaft for badminton rackets includes the following steps:

[0015] A. A cylindrical membrane is fitted onto the mold tube;

[0016] B. Tear off the carbon fiber layer and stick it to the cylindrical membrane of the mold tube;

[0017] C. Rotating the mold tube causes the carbon fiber layer to be placed on the tube winding machine;

[0018] D. The tube winding machine is started to wind the carbon fiber layer onto the mold tube to form a carbon fiber tube;

[0019] E. Remove the carbon fiber tube for the next processing step.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is a badminton racket carbon fiber tube winding and forming machine. A film is applied to the mold tube by a film assembly, and then the carbon fiber layer is adhered. The material is then conveyed to a tube winding machine for winding to form a carbon fiber tube. Because the carbon fiber layer is adhered to the film and is not directly connected to the mold tube, the carbon fiber tube can be removed directly by removing the film. The mold tube can be easily removed without affecting the carbon fiber tube, thus ensuring the quality of the carbon fiber tube.

[0022] 2. In the badminton racket carbon fiber tube coiling and forming machine of the present invention, when the membrane is sleeved on the mold tube, the rotating motor drives the threaded rod to rotate, thereby multiple sliding nuts carrying the first wedge block to move towards the second wedge block. The first wedge block and the second wedge block cooperate to push the four support plates to stretch the elastic elements outward, abutting against the inside of the membrane to form a fixed shape. After the carbon fiber tube is prepared, the rotating motor drives the threaded rod to rotate in the opposite direction, the multiple sliding nuts carrying the first wedge block reset, and the four support plates reset by the elastic force of the elastic elements, so that the membrane loses its abutment and is easier to remove. The setting of the four support plates can adapt to membranes of different diameters.

[0023] 3. The badminton racket carbon fiber tube coiling and forming machine of the present invention, when the carbon fiber layer is waiting to be glued, places the carbon fiber layer on the carbon fiber placement platform, and uses multiple adsorption holes to adsorb and fix the carbon fiber layer. Then, the protective film of the adhesive layer on the carbon fiber layer is peeled off by a moving frame and a lifting cylinder, thereby realizing automatic film removal.

[0024] 4. The badminton racket carbon fiber tube coiling and forming machine of the present invention uses a lifting gripper to lower and grab a cylindrical membrane, and then raises it so that one opening of the cylindrical membrane is facing the air outlet of the blower. The blower blows air onto the cylindrical membrane, blowing it completely open. The continuous blowing of the blower fills the cylindrical membrane with air, thus keeping the cylindrical membrane straight. Then, the horizontal moving seat drives the cylindrical membrane to be fitted onto the mold tube.

[0025] 5. The badminton racket carbon fiber tube molding process of the present invention involves applying a film over the mold tube to facilitate the subsequent removal of the carbon fiber tube. Attached Figure Description

Detailed Implementation

[0039] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0040] like Figures 1-9As shown, this embodiment provides a badminton racket carbon fiber tube coiling and forming machine, including a tube coiling machine 1, a rotator 2, and a film assembly 3. The rotator 2 is installed on one side of the tube coiling machine 1, and the film assembly 3 is installed on the side of the rotator 2 away from the tube coiling machine 1. Four mold tubes 4 are equidistantly arranged on the rotating end of the rotator 2. The mold tubes 4 are rotatably connected to the rotating end of the rotator 2. A lifting groove 201 is opened on the rotating end of the rotator 2 corresponding to the position of the mold tubes 4. The mold tubes 4 are provided with a rotating disk 401 placed in the lifting groove 201. Elastic elements 202 are respectively installed at the upper and lower ends of the lifting groove 201, and the rotating disk 401 is placed between the two elastic elements 202. The film is applied to the mold tube 4 by the film assembly 3, and then the carbon fiber layer is adhered. The mold tube is then placed in the winding machine 1 to be wound to form a carbon fiber tube. Since the carbon fiber layer is adhered to the film and is not directly connected to the mold tube 4, the carbon fiber tube can be removed directly by removing the film. The mold tube 4 can be easily removed without affecting the carbon fiber tube, thus ensuring the quality of the carbon fiber tube. Furthermore, the elastic element 202 and the lifting groove 201 are provided so that the mold tube 4 can have adaptive vertical movement space.

[0041] Furthermore, a threaded rod 402 is rotatably provided inside the mold tube 4, and a rotary motor 403 is provided inside the mold tube 4 to drive the threaded rod 402 to rotate. Multiple sliding nuts 405 are rotatably engaged on the threaded rod 402. The sliding nuts 405 are moved and placed inside the mold tube 4. First wedge blocks 406 are provided at equal intervals along the axis of the threaded rod 402 on the sliding nuts 405. The mold tube 4 is provided with sliding grooves for the first wedge blocks 406 to slide. Four support plates 407 are provided outside the mold tube 4. The support plates 407 are connected to the mold tube 4 by springs 408. Second wedge blocks 409 are provided on the support plates 407 at positions corresponding to the sliding grooves to cooperate with the first wedge blocks 406. When the membrane is fitted onto the mold tube 4, the rotating motor 403 drives the threaded rod 402 to rotate, thereby causing multiple sliding nuts 405 to move towards the second wedge block 409 along with the first wedge block 406. The first wedge block 406 and the second wedge block 409 cooperate to push the four support plates 407 to stretch the spring 408 outward, thus abutting against the inside of the membrane to form a fixed shape. After the carbon fiber tube is prepared, the rotating motor 403 drives the threaded rod 402 to rotate in the opposite direction, and the multiple sliding nuts 405 return to their original position along with the first wedge block 406. The four support plates 407 return to their original position due to the elastic force of the spring 408, so that the membrane loses its abutment and is easier to remove. The arrangement of the four support plates 407 can accommodate membranes of different diameters.

[0042] Furthermore, the tube winding machine 1 includes a worktable 101, a winding plate 102, and a lifting platform 103. The winding plate 102 is movably mounted on the worktable 101, and the worktable 101 is equipped with a drive cylinder for moving the winding plate 102. The lifting platform 103 is mounted on the worktable 101, and its lifting plate is positioned above the winding plate 102. During winding, the mold tube 4 is placed on the winding plate 102, and the lifting platform 103 drives the lifting plate to descend and press it onto the mold tube 4. Then, the drive cylinder drives the winding plate 102 to move horizontally, twisting the carbon fiber layer onto the mold tube 4 to form a carbon fiber tube.

[0043] Furthermore, the rotary device 2 includes a mounting plate 203, a lifting device 204, and a rotary motor 205. The mounting plate 203 is installed on one side of the tube winding machine 1, the lifting device 204 is installed on the mounting plate 203, the rotary motor 205 is installed on the lifting end of the lifting device 204, and four mold tubes 4 are equidistantly installed on the rotating end of the rotary motor 205. The mold tubes 4 are driven by the cooperation of the lifting device 204 and the rotary motor 205 to transfer between various devices.

[0044] Furthermore, a carbon fiber placement platform 5 is mounted on one side of the lifting device 204 on the mounting plate 203. Specifically, the carbon fiber placement platform 5 has multiple adsorption holes 501 evenly distributed on it. A vacuum adsorption machine communicating with the adsorption holes 501 is installed inside the carbon fiber placement platform 5. A support frame 502 is mounted on the mounting plate 203, and a movable frame 503 is mounted above the carbon fiber placement platform 5 on the support frame 502. A lifting cylinder 504 is mounted on the movable frame 503, with its lifting end facing the carbon fiber placement platform 5. A swing gripper is installed on the lifting end of the lifting cylinder 504. When the carbon fiber layer is ready to be bonded, it is placed on the carbon fiber placement platform 5. The carbon fiber layer is adsorbed and fixed through the multiple adsorption holes 501, and the protective film of the adhesive layer on the carbon fiber layer is peeled off by the movable frame 503 in conjunction with the lifting cylinder 504, achieving automatic film removal.

[0045] Furthermore, the swing gripper includes a swing motor 505, a rough panel 506, and a vacuum suction component 507. The swing motor 505 is mounted on the lifting end of the lifting cylinder 504, and the rough panel 506 is mounted on the swing end of the swing motor 505. The rough surface of the rough panel 506 faces the carbon fiber placement platform 5, and the vacuum suction component 507 is mounted on one side of the rough panel 506. The swing motor 505 drives the rough panel 506 to tilt, and the lifting cylinder 504 drives it to descend, so that the rough surface of the rough panel 506 fits against one side of the protective film. The moving frame 503 drives it to move, so that the rough surface of the rough panel 506 rubs against the protective film, thereby causing the protective film to curl up at the edge. The swing motor 505 then straightens the rough panel 506, and the vacuum suction component 507 adsorbs and fixes the protective film. Finally, the moving frame 503 peels off the protective film. By first curling up the edge of the protective film before peeling it off, the protective film can be easily removed.

[0046] Furthermore, the membrane assembly 3 includes a membrane frame 301, a lifting gripper 302, a horizontal moving seat 303, a lifting gripper 304, and a blower 305. The membrane frame 301 is located on one side of the rotator 2. The lifting gripper 302 is mounted on the membrane frame 301. The horizontal moving seat 303 is movably mounted on top of the lifting gripper 302, and the lifting gripper 302 is equipped with a screw system to drive the horizontal moving seat 303. The lifting gripper 304 and the blower 305 are both mounted on the horizontal moving seat 303, and the air outlet of the blower 305 faces the rotator 2. Specifically, the membrane frame 301 is provided with a membrane receiving groove, the bottom of the membrane receiving groove is provided with a lifter 306, the opening of the membrane receiving groove is provided with a pressure block 307, and a cylindrical membrane is placed between the lifter 306 and the pressure block 307. The lifting gripper 304 lowers to grab a cylindrical membrane and then rises so that one opening of the cylindrical membrane is directly facing the air outlet of the blower 305. The blower 305 blows air, which blows the cylindrical membrane open completely. The continuous blowing of the blower 305 fills the cylindrical membrane with air, keeping it straight. Then, the horizontal moving seat 303 drives the cylindrical membrane to be fitted onto the mold tube 4.

[0047] The molding process of carbon fiber shaft for badminton rackets includes the following steps:

[0048] A. A cylindrical membrane is fitted onto the mold tube 4;

[0049] B. Tear off the carbon fiber layer and stick it to the cylindrical membrane of the mold tube 4;

[0050] C. Rotating the mold tube 4 causes the carbon fiber layer to be placed on the tube winding machine 1;

[0051] D. The tube winding machine 1 is started to wind the carbon fiber layer onto the mold tube 4 to form a carbon fiber tube;

[0052] E. Remove the carbon fiber tube for the next processing step.
