[0002] A wire stranding machine is a kind of mechanical equipment that can be widely used for stranding various soft / hard conductor wires. It can twist multiple single conductors into one strand to meet the process requirements of the wire. Therefore, a wire and cable stranding machine is needed in the cable production process.

[0003] Existing wire and cable stranding machines, such as the wire and cable processing stranding machine proposed in Publication No.: CN118507159A, include a base and a cage, the cage is mounted on the top of the base through meshing gears, the meshing gear is connected to a motor transmission fixed to one side of the base through a toothed belt transmission, and the output end of the motor is connected to a sub-control mechanism; a top seat, the top seat is arranged between the cage and the base, the top seat is moved closer to or farther from the base through two sets of telescopic frames arranged below the top seat, and the base is rotatably arranged on the top of the base; a fixing mechanism, the fixing mechanism is arranged at a position close to the meshing gear at the top of the base, and the fixing mechanism clamps and fixes the meshing gear through a sub-control mechanism.

[0004] The existing wire and cable twisting machine has a compact and simple structure and can protect the use of the motor. However, it is found in use that when the twisting machine is working, the material roller needs to rotate with the cage.

The twisting machine can only continue to work after all the material rollers are replaced, resulting in a long downtime of the twisting machine, which makes the overall working efficiency of the twisting machine low and inconvenient to use. Therefore, we propose a wire and cable twisting machine to solve the problem raised. Summary of the invention

Place the material roller to be installed on the shaft groove through the shaft, and rotate the adjusting screw in the reverse direction to make the limiting frames approach each other and limit the shaft in the shaft groove, then the installation of the material roller can be completed. Through the quick disassembly and assembly mechanism of the material roller, the material roller can be quickly replaced, effectively improving the working efficiency of the material roller. And when the material roller rotates through the shaft, the rolling friction formed by the shaft and the ball replaces the sliding friction between the shaft and the shaft groove, effectively reducing the friction force received when the material roller rotates, so that the material roller can feed the material through rotation.

[0029] Embodiment:

[0030] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a wire and cable stranding machine, including a base 1, a rotary seat 2 is rotatably connected to the top of one side of the base 1, and the rotary seat 2 is driven by a driving mechanism to rotate, wherein,

[0031] A bracket 7 is fixedly connected to the top of the rotating base 2. Support shafts 8 are symmetrically and fixedly connected to both sides of the bracket 7. A turntable 9 is rotatably connected to the support shafts 8. Material rollers 10 are symmetrically installed on one side of the turntable 9 away from the bracket 7. The material rollers 10 are installed on the turntable 9 through a quick disassembly and assembly mechanism. A sliding seat 20 is slidably arranged on the top of the other side of the base 1. A second chute 21 is opened at the top of the base 1 corresponding to the sliding seat 20. A second slider 22 is fixedly connected to the bottom of the sliding seat 20 corresponding to the second chute 21. A lead screw 23 threaded to the second slider 22 is rotatably connected in the second chute 21. A second motor 24 is installed at one end of the base 1 corresponding to the sliding seat 20. The shaft end of the second motor 24 is fixedly connected to the lead screw 23. The middle of the top end of the sliding seat 20 is fixedly connected to a support frame 25. A main shaft 26 is rotatably connected to the support frame 25;

[0032] First wire holes 27 are annularly and equidistantly distributed on the main shaft 26. A first wire reel 28 is fixedly connected to one end of the main shaft 26 away from the rotating base 2. A second wire hole 29 penetrates through the position of the first wire reel 28 corresponding to the first wire holes 27. A second wire reel 30 is fixedly connected to one end of the main shaft 26 close to the rotating base 2. A third wire hole 31 penetrates through the side of the second wire reel 30 corresponding to the first wire holes 27. First guide wheels 32 are symmetrically and rotatably connected to both sides of the second wire reel 30 corresponding to the third wire hole 31. A second guide wheel 33 is rotatably connected to the position of the second wire reel 30 corresponding to the first wire holes 27. A transmission wheel 34 is fixedly connected to the middle of one side of the turntable 9 away from the bracket 7. Slots 35 are equidistantly opened on one side of the transmission wheel 34 away from the turntable 9. A plug rod 36 is fixedly connected to one side of the second wire reel 30 corresponding to the slots 35. The main shaft 26 is driven to rotate by an electric mechanism;

[0033] When the stranding machine is working, the electric mechanism drives the main shaft 26 to rotate. The main shaft 26 drives the first wire reel 28 and the second wire reel 30 to rotate. The second wire reel 30 inserts the plug rod 36 into the slots 35 inside the transmission wheel 34, so that the second wire reel 30 drives the corresponding turntable 9 to rotate through the transmission wheel 34, and the material rollers 10 on the turntable 9 release materials to strand the cable. By arranging two groups of turntables 9, when one group of turntables 9 is working, the material rollers 10 on the other group of turntables 9 can be replaced. While replacing the material rollers 10, the stranding machine can continue to work, avoiding the long-term shutdown of the stranding machine and effectively improving the overall working efficiency of the stranding machine.

[0034] Please refer to Figures 1 to 7, the driving mechanism includes a transmission groove 3. A transmission groove 3 is provided inside the base 1 corresponding to the rotating seat 2. A worm gear 4 is fixedly connected to the shaft end of the rotating seat 2 corresponding to the transmission groove 3. A worm 5 is rotatably connected inside the transmission groove 3 near the worm gear 4. A first motor 6 is installed at the outer end of the base 1 corresponding to the worm 5. The shaft end of the first motor 6 is fixedly connected to the worm 5. The installation position of the material roller 10 corresponds to the positions of the first wire hole 27, the second wire hole 29, and the third wire hole 31. When it is necessary to convert the turntable 9, the second motor 24 is driven to drive the lead screw 23 to rotate, so that the lead screw 23 drives the sliding seat 20 to move away from the rotating seat 2 through the second slider 22, so that the second wire reel 30 drives the insertion rod 36 to move out of the insertion slot 35, and the first motor 6 is driven to drive the worm 5 to rotate. The worm 5 drives the rotating seat 2 to rotate 180° through the engagement with the worm gear 4 to exchange the position of the turntable 9. After that, the second motor 24 is driven to drive the lead screw 23 to rotate in the reverse direction, so that the sliding seat 20 moves towards the rotating seat 2, so that the second wire reel 30 drives the insertion rod 36 to insert into the insertion slot 35, and the stranding machine continues to work.

[0035] Please refer to Figures 1 to 7, The quick disassembly and assembly mechanism includes a mounting base 11. Mounting bases 11 are symmetrically arranged at positions of the turntable 9 corresponding to the material rollers 10. On both sides of the mounting base 11, limiting frames 12 are symmetrically and fixedly connected. Inside the limiting frames 12, rotating shaft grooves 13 are provided. At one end of the material roller 10 corresponding to the rotating shaft groove 13, a rotating shaft 14 is fixedly connected. Inside the inner wall of the rotating shaft groove 13, ball grooves 15 are equidistantly provided. Inside the ball grooves 15, balls 16 are rotatably connected. On one side of the turntable 9 close to the mounting base 11, a first sliding groove 17 is provided. On one side of the mounting base 11 corresponding to the first sliding groove 17, a first sliding block 18 is fixedly connected. Inside the first sliding groove 17, a lead screw 23 is rotatably connected. The end of the lead screw 23 penetrates through the inside of the turntable 9 and extends to the outside. The ball 16 is a sphere, and the outer diameter of the ball 16 matches the inner diameter of the ball groove 15. There are two sections of opposite external threads provided on the lead screw 23, and the lead screw 23 is threadedly connected to the first sliding blocks 18 on both sides through the two sections of opposite external threads respectively. When replacing the material roller 10 on the stopped turntable 9, rotate the corresponding adjusting screw 19. The adjusting screw 19 drives the first sliding blocks 18 on both sides to move in opposite directions through the two sections of opposite external threads, so that the mounting bases 11 on both sides of the material roller 10 move away from each other, causing the mounting base 11 to drive the limiting frames 12 to move away from each other, opening the rotating shaft groove 13, enabling the material roller 10 to drive the rotating shaft 14 to move out of the rotating shaft groove 13. Place the material roller 10 to be installed on the rotating shaft groove 13 through the rotating shaft 14. Rotate the adjusting screw 19 in the reverse direction to make the limiting frames 12 approach each other and limit the rotating shaft 14 in the rotating shaft groove 13, then the installation of the material roller 10 can be completed. Through the quick disassembly and assembly mechanism of the material roller 10, the material roller 10 can be quickly replaced, effectively improving the working efficiency of the material roller 10. And when the material roller 10 rotates through the rotating shaft 14, the rolling friction formed by the rotating shaft 14 and the ball 16 replaces the sliding friction between the rotating shaft 14 and the rotating shaft groove 13, effectively reducing the friction force received when the material roller 10 rotates, so that the material roller 10 can discharge materials through rotation.

[0036] Please refer to Figures 1 to 7 , The opening of the slot 35 is in a flared shape, and the inner diameter of the slot 35 matches the outer diameter of the plug rod 36. The electric mechanism includes a third motor 37. The third motor 37 is installed on one side of the support frame 25. On the outside of the main shaft 26 corresponding to the third motor 37, a first reversing gear 38 is fixedly connected. On the shaft end of the third motor 37 corresponding to the first reversing gear 38, a second reversing gear 39 is fixedly connected. The first reversing gear 38 is annular, and the first reversing gear 38 meshes with the second reversing gear 39.

[0037] Working principle: For a wire and cable stranding machine, when the stranding machine is working, the third motor 37 drives the second reversing gear 39 to rotate. The second reversing gear 39 drives the main shaft 26 to rotate through meshing with the first reversing gear 38. The main shaft 26 drives the first wire reel 28 and the second wire reel 30 to rotate. The second wire reel 30 inserts the insertion rod 36 into the slot 35 inside the transmission wheel 34, so that the second wire reel 30 drives the corresponding turntable 9 to rotate through the transmission wheel 34, and the material roller 10 on the turntable 9 feeds the material to strand the cable. By setting two groups of turntables 9, when one group of turntables 9 is working, the material roller 10 on the other group of turntables 9 can be replaced. When it is necessary to switch the turntable 9, the second motor 24 drives the lead screw 23 to rotate. The lead screw 23 drives the sliding seat 20 to move away from the rotating seat 2 through the second slider 22, so that the second wire reel 30 drives the insertion rod 36 to move out of the slot 35, and the first motor 6 drives the worm 5 to rotate. The worm 5 drives the rotating seat 2 to rotate 180° through meshing with the worm gear 4 to switch the position of the turntable 9. Then, the second motor 24 drives the lead screw 23 to rotate in the reverse direction, so that the sliding seat 20 moves towards the rotating seat 2, and the second wire reel 30 drives the insertion rod 36 to insert into the slot 35 inside, so that the stranding machine continues to work;

[0038] When replacing the material roller 10 on the turntable 9 that has stopped working, rotate the corresponding adjusting screw 19. The adjusting screw 19 drives the first sliders 18 on both sides to move in opposite directions through two sections of opposite external threads, so that the mounting seats 11 on both sides of the material roller 10 move away from each other, and the mounting seats 11 drive the limiting frames 12 to move away from each other, opening the rotating shaft groove 13, so that the material roller 10 drives the rotating shaft 14 to move out of the rotating shaft groove 13. Place the material roller 10 to be installed on the rotating shaft groove 13 through the rotating shaft 14, and rotate the adjusting screw 19 in the reverse direction to make the limiting frames 12 approach each other and limit the rotating shaft 14 in the rotating shaft groove 13, then the installation of the material roller 10 can be completed. Through the quick disassembly and assembly mechanism of the material roller 10, the material roller 10 can be quickly replaced, effectively improving the working efficiency of the material roller 10. And when the material roller 10 rotates through the rotating shaft 14, the rolling friction formed by the rotating shaft 14 and the ball 16 replaces the sliding friction between the rotating shaft 14 and the rotating shaft groove 13, effectively reducing the friction force received when the material roller 10 rotates, so that the material roller 10 can feed the material through rotation.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
