[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:
[0023] A high-speed stranding machine anti-winding tension adjustment mechanism includes a support frame 1. A stranding machine 2 is rotatably connected inside the support frame 1, and a winding drum 3 is rotatably connected outside the stranding machine 2. The surface of the winding drum 3 has a through groove. A winding post 4 is rotatably connected inside the winding drum 3. A magnetic damper 5 is rotatably connected to the top of the winding post 4. A disc 6 is fixedly connected to the top of the magnetic damper 5. An mounting cylinder 7 is fixedly connected to the inner wall of the disc 6. The mounting cylinder 7 has an open design. A mounting base 8 is fixedly connected to the top of the winding post 4. A sleeve 9 is fixedly connected inside the mounting base 8. A hook 10 is rotatably connected inside the sleeve 9. The hook 10 is adapted to the mounting cylinder 7. By placing the support frame 1 in a designated position, the stranding machine 2 is then driven by a motor to... The winding cylinder 4 is rotated by passing the wire through the slot and winding it around the outside of the winding cylinder 4. After the stranding machine 2 is driven, the multiple strands of wire are stranded together. When the stranding machine 2 stops, the wire will continue to rotate under the action of tension, causing the wire on the winding cylinder 4 to loosen. The magnetic damper 5 is set to effectively prevent the winding cylinder 4 from continuing to rotate after it stops. By rotating the disc 6, eddy current resistance is generated inside the magnetic damper 5, and the induction intensity between the two sets of magnets inside it is realized to generate resistance after the rotation of the winding cylinder 4 stops, preventing the wire from loosening. The adjusted magnetic damper 5 is fixed by inserting the hook 10 into the inside of the mounting cylinder 7. Multiple sets of mounting cylinders 7 are designed to achieve fixed fixation after adjusting different resistances.
[0024] Furthermore, in this embodiment, a movable rod 11 is slidably connected to the middle of the sleeve 9, and an mounting sleeve 12 is fixedly connected to the outside of the movable rod 11. A mounting ear 13 is symmetrically fixedly connected to the bottom end of the mounting sleeve 12. The hook 10 is rotatably connected to the sleeve 9 through the mounting ear 13. By rotating the movable rod 11 inside the sleeve 9, the mounting sleeve 12 moves synchronously with the movable rod 11. Then, the mounting ear 13 applies a pushing force to the hook 10, so that the hook 10 extends to the outside of the sleeve 9.
[0025] Furthermore, in this embodiment, there are two sets of hooks 10, and each set of hooks 10 has a limiting groove 14 on its surface. The limiting groove 14 has a figure-eight structure design. A limiting rod 15 is fixedly connected to the inner wall of the sleeve 9. The limiting rod 15 extends to the outside of the limiting groove 14 and slides with the limiting groove 14. When the hook 10 extends, the limiting groove 14 will slide outside the limiting rod 15. Due to the figure-eight shape, the two sets of hooks 10 can move closer to each other. After the hook 10 enters the installation cylinder 7, the moving rod 11 is reset, so that the hook 10 unfolds inside the installation cylinder 7. Then the hook 10 squeezes the inner wall of the installation cylinder 7 and generates a pulling force to fix the disc 6.
[0026] Furthermore, in this embodiment, a limiting frame is fixedly connected to the bottom end of the inner side of the sleeve 9. A transverse groove 16 is provided inside the limiting frame, and the interiors of the limiting frame and the transverse groove 16 are interconnected. A mounting post 17 is slidably connected inside the limiting frame. The moving rod 11 is fixedly connected to the top of the mounting post 17. An inclined groove 18 is provided inside the mounting post 17. A pressing post 19 is slidably connected inside the transverse groove 16. The pressing post 19 passes through the outside of the inclined groove 18 and is slidably connected to the inclined groove 18. The diameter of the right end of the pressing post 19 decreases sequentially. By sliding the pressing post 19, it slides inside the inclined groove 18. At the same time, the side with the larger diameter of the pressing post 19 will press the mounting post 17, applying tension to the mounting post 17. The mounting post 17 will slide inside the limiting frame. Meanwhile, a spring is provided outside the connection between the moving rod 11 and the mounting post 17. When the moving rod 11 slides down synchronously with the mounting post 17, the mounting sleeve 12 will press the spring.
[0027] Furthermore, in this embodiment, a threaded rod 20 is rotatably connected to the left end of the extrusion column 19. A threaded groove is provided on the inner side wall of the transverse groove 16 at a position corresponding to the threaded rod 20. The threaded rod 20 extends to the outside of the sleeve 9. By rotating the threaded rod 20, it then undergoes a threaded reaction with the threaded groove, realizing the spiral movement of the threaded rod 20 outside the transverse groove 16 and generating a pulling force on the extrusion column 19, thereby enabling the extrusion column 19 to slide.
[0028] Furthermore, in this embodiment, a bidirectional lead screw 21 is rotatably connected inside the winding post 4, and a connecting ring 22 is sleeved on the outside of the bidirectional lead screw 21. The connecting ring 22 moves axially along the bidirectional lead screw 21, and a limiting strip is fixedly connected to the outside of the connecting ring 22. A vertical groove 23 is opened on the surface of the winding post 4 at a position corresponding to the limiting strip. A retaining ring 24 is fixedly connected to the end of the limiting strip away from the connecting ring 22. The retaining ring 24 is slidably connected to the outside of the winding post 4. By moving the bidirectional lead screw 21, the connecting ring 22 reacts with it through a thread, and under the limiting action of the limiting strip, the two sets of retaining rings 24 move closer to each other. The area between the winding posts 4 can be contracted according to the width of the outer wire of the winding post 4.
[0029] In this embodiment, the specific implementation scenario is as follows: The support frame 1 is placed in a designated position, and then the stranding machine 2 is driven by a motor to rotate. The wire is passed through the through groove and wound around the outside of the winding post 4. After the stranding machine 2 is driven, multiple strands of wire are stranded together. When the stranding machine 2 stops, the wire, under tension, will still drive the winding drum 3 to continue rotating, causing the wire on the winding post 4 to loosen. A magnetic damper 5 is used to effectively prevent the winding post 4 from continuing to rotate after stopping. The disc 6 is rotated, thereby generating eddy current resistance inside the magnetic damper 5, achieving the induction intensity between the two sets of magnets inside, thus resisting the rotation of the winding post 4. The hook 10 is inserted into the installation cylinder 7, and the threaded rod 20 is rotated, subsequently reacting with the threaded groove, causing the threaded rod 20 to spiral outside the transverse groove 16, generating tension on the extrusion post 19, causing the extrusion post 19 to slide. At this time, the extrusion post 19 is inside the inclined groove 18. The sliding action, along with the compression post 19's larger diameter side, compresses the mounting post 17, applying tension to it. The mounting post 17 slides inside the limiting frame. Simultaneously, a spring is installed outside the connection between the moving rod 11 and the mounting post 17. When the moving rod 11 slides down synchronously with the mounting post 17, the mounting sleeve 12 compresses the spring, causing the mounting sleeve 12 to move synchronously with the moving rod 11. Subsequently, the mounting ear 13 applies tension to the hook 10, and the limiting groove 14 slides outside the limiting rod 15. Due to its V-shape, the two sets of hooks 10 unfold towards each other. Then, the hooks 10 extend out of the hollow part of the mounting cylinder 7, compressing its sidewall and generating tension to fix the disc 6. By moving the bidirectional lead screw 21, the connecting ring 22 reacts with it through a thread. Under the limiting action of the limiting strip, the two sets of retaining rings 24 move closer to each other. The area between the winding posts 4 can be contracted according to the width of the outer wire of the winding post 4.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
