Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a cage stranding machine for producing fire-resistant low-voltage cables. Background Technology

[0002] A cable winch is a device used to winch wires and cables. It is driven by a power source such as a motor to rotate the auger. During the rotation, the single wires placed in the wire release device are released under tension control and then gradually winch together under the rotation of the auger to form a thicker cable core. This winch method can make the core structure compact and round.

[0003] However, when using traditional cage stranding machines to produce fire-resistant low-voltage cables, the cables tend to pile up excessively in a fixed position during stranding, resulting in uneven stranding. This causes stress concentration inside the cable, affecting cable quality and making it prone to damage during use, such as localized breakage or decreased conductivity.

[0004] Therefore, it is necessary to provide a new cage stranding machine for the production of fire-resistant low-voltage cables to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a cage stranding machine for the production of fire-resistant low-voltage cables that is easy to use, produces uniform stranding, and reduces wear between cables and equipment.

[0006] To solve the above-mentioned technical problems, the present invention provides a cage stranding machine for producing fire-resistant low-voltage cables, comprising: a fixed plate, a base and a second support plate fixedly mounted on the top of the fixed plate, a take-up roller rotatably mounted on the second support plate, a second motor fixedly mounted on one side of the second support plate, the output shaft of the second motor being fixedly connected to one end of the take-up roller, a rotating disk provided inside the base, a plurality of winding drums slidably mounted on the rotating disk, a ring rack fixedly mounted on the outer wall of the rotating disk, a second rotating rod rotatably mounted inside the base, a gear fixedly mounted on the outer side of the second rotating rod, the gear meshing with the ring rack, a first motor fixedly mounted on the top of the fixed plate and a first rotating rod rotatably mounted thereon, the output shaft of the first motor being fixedly connected to one end of the first rotating rod, one end of the second rotating rod extending outside the base, pulleys fixedly mounted on the outer sides of both the second rotating rod and the first rotating rod, and the same belt sleeved on the outer sides of the two pulleys.

[0007] Preferably, two first support plates are fixedly installed on the top of the fixed plate. A guide roller is rotatably installed on the side of the two first support plates that are close to each other. A take-up drum is provided on the top of the guide roller. A connecting rod is fixedly installed on the bottom end of the take-up drum. A third roller is rotatably installed on the end of the connecting rod away from the take-up drum. A guide groove is provided on the guide roller. The outer wall of the third roller contacts the guide groove. One end of the guide roller extends outside the first support plate and is fixedly installed with a second bevel tooth. A first bevel tooth is fixedly installed on the end of the first rotating rod away from the first motor. The first bevel tooth meshes with the second bevel tooth.

[0008] Preferably, a plurality of first rollers are rotatably mounted on the outer wall of the rotating disk, and the outer walls of the plurality of first rollers are in contact with the inner wall of the base.

[0009] Preferably, the rotating disk has multiple connecting ports, and grooves are provided on both sides of the multiple connecting ports. A second guide rod is fixedly installed in each of the two grooves, and the winding spool is slidably installed on the two second guide rods.

[0010] Preferably, springs are fitted on the outer sides of both second guide rods, and the two ends of the springs are fixedly connected to the rotating disk and the winding drum, respectively.

[0011] Preferably, the same first guide rod and guide plate are fixedly installed on the side of the two first support plates that are close to each other. The top end of the take-up drum is slidably installed on the first guide rod. The connecting rod passes through the guide plate. A second roller is also rotatably installed on the connecting rod.

[0012] Compared with related technologies, the cage stranding machine for producing fire-resistant low-voltage cables provided by this utility model has the following beneficial effects:

[0013] This utility model provides a cage stranding machine for producing fire-resistant low-voltage cables. It utilizes a first motor, belt, second rotating rod, first rotating rod, first roller, gear, connecting port, groove, spring, ring rack, rotating disc, and winding drum in coordination. When the rotating disc rotates, the cable passing through the sliding winding drum twists accordingly, enabling multiple cables to be regularly stranded together. Because the winding drum can slide, the rotating disc allows for better adjustment of the cable's position during stranding, resulting in a tighter and more uniform stranding. This prevents damage to the cable due to excessive twisting or mutual compression, reducing the risk of the cable sheath being torn or worn. The machine incorporates a first rotating rod, first conical gear, second conical gear, guide roller, guide groove, and winding drum. The connecting rod and the third roller work together, and the guide roller rotates to allow the cable's position to change continuously during the twisting process. This helps prevent the cable from piling up excessively or twisting too tightly at a fixed position, allowing the cable to twist more evenly when passing through the drum. This avoids uneven twisting, stress accumulation in certain areas, and potential damage to the cable during use. The first guide rod, guide plate, second roller, and second guide rod work together to ensure that the cable accurately enters the winding drum, take-up drum, and wraps around the take-up roller. This prevents the cable from deviating from the predetermined path, which could lead to uneven twisting or messy winding. It ensures that the cable is guided to operate at the optimal angle and path, achieving more uniform twisting and neat winding. Attached Figure Description

Figure 3 for Figure 1 The diagram shown is a top view of the structure. Figure 4 for Figure 1 The diagram shows a partial sectional view of the structure. Figure 5 for Figure 3 The diagram shows a top view of the guide roller. Figure 6 for Figure 5The diagram shows a bottom view of the guide roller. The cage stranding machine for producing fire-resistant low-voltage cables includes: a fixed plate 1, a base 7 and a second support plate 8 fixedly mounted on the top of the fixed plate 1, a take-up roller 22 rotatably mounted on the second support plate 8, a second motor 21 fixedly mounted on one side of the second support plate 8, and an output shaft of the second motor 21 fixedly connected to one end of the take-up roller 22. A rotating disk 18 is provided inside the base 7. When the rotating disk 18 rotates, the cable passing through the slidable winding drum 10 twists accordingly, enabling multiple cables to be regularly stranded together. Multiple winding drums 10 are slidably mounted on the rotating disk 18. Because the winding drums 10 can slide, the rotation of the rotating disk 18 allows the cable to be better positioned during the stranding process, thus improving the stranding efficiency. The coupling is tighter and more uniform, avoiding damage to the cable due to excessive twisting or mutual compression. A ring rack 23 is fixedly installed on the outer wall of the rotating disk 18. A second rotating rod 6 is rotatably installed inside the base 7. A gear 28 is fixedly installed on the outer side of the second rotating rod 6. The gear 28 meshes with the ring rack 23. A first motor 4 is fixedly installed on the top of the fixed plate 1 and a first rotating rod 3 is rotatably installed. The output shaft of the first motor 4 is fixedly connected to one end of the first rotating rod 3. One end of the second rotating rod 6 extends outside the base 7. Pulleys are fixedly installed on the outer side of both the second rotating rod 6 and the first rotating rod 3. The same belt 5 is sleeved on the outer side of the two pulleys.

[0023] Two first support plates 2 are fixedly installed on the top of the fixed plate 1. The same guide roller 11 is rotatably installed on the side of the two first support plates 2 that are close to each other. When the guide roller 11 rotates, the position of the cable can change continuously during the twisting process, which helps to avoid excessive accumulation or twisting of the cable at a fixed position. The top of the guide roller 11 is provided with a take-up drum 14. A connecting rod 15 is fixedly installed at the bottom end of the take-up drum 14. A third roller 17 is rotatably installed at the end of the connecting rod 15 away from the take-up drum 14. The guide roller 11 is provided with a guide groove 29. The outer wall of the third roller 17 contacts the guide groove 29. This arrangement can avoid uneven twisting and stress accumulation in certain parts of the take-up roller 22, which may cause damage to the cable during use. One end of the guide roller 11 extends outside the first support plate 2 and is fixedly installed with a second bevel tooth 20. The end of the first rotating rod 3 away from the first motor 4 is fixedly installed with a first bevel tooth 19. The first bevel tooth 19 meshes with the second bevel tooth 20.

[0024] The outer wall of the rotating disk 18 is rotatably mounted with a plurality of first rollers 9, and the outer walls of the plurality of first rollers 9 are in contact with the inner wall of the base 7.

[0025] The rotating disk 18 is provided with multiple connecting ports 27, and each of the multiple connecting ports 27 has a groove 26 on both sides. A second guide rod 24 is fixedly installed in each of the two grooves 26, and the winding drum 10 is slidably installed on the two second guide rods 24.

[0026] Springs 25 are fitted on the outer sides of the two second guide rods 24, and the two ends of the springs 25 are fixedly connected to the rotating disk 18 and the winding drum 10, respectively.

[0027] The same first guide rod 13 and guide plate 12 are fixedly installed on the side of the two first support plates 2 that are close to each other. The top end of the take-up drum 14 is slidably installed on the first guide rod 13. The connecting rod 15 passes through the guide plate 12. A second roller 16 is also rotatably installed on the connecting rod 15. The outer wall of the second roller 16 is in contact with the inner wall of the guide plate 12.

[0028] The working principle of the cage stranding machine for producing fire-resistant low-voltage cables provided by this utility model is as follows:

[0029] First, multiple cables are passed through multiple winding drums 10. Then, the first motor 4 and the second motor 21 are started. The output shaft of the first motor 4 drives the first rotating rod 3 to rotate, and the output shaft of the second motor 21 drives the take-up roller 22 to rotate. The belt 5 drives the gear 28 to rotate, and the gear 28 drives the rotating disk 18 to rotate, which can regularly twist multiple cables together. Since the winding drums 10 can slide, the rotating disk 18 can better adjust the position of the cables during the twisting process. Then, the twisted cables are passed through the take-up drum 14 and wound around the take-up roller 22. The first rotating rod 3 drives the guide roller 11 to rotate through the cooperation of the first bevel tooth 19 and the second bevel tooth 20. The guide roller 11 drives the take-up drum 14 to move continuously through the guide groove 29, so as to avoid the cables from being excessively piled up or twisted too tightly at a certain fixed position on the take-up roller 22, and to prevent uneven twisting and stress accumulation in certain parts, which could lead to damage to the cables during use.

The machine also incorporates a first rotating rod 3, first conical tooth 19, second conical tooth 20, guide roller 11, and guide groove. 29. The take-up drum 14, connecting rod 15, and third roller 17 work together. When the guide roller 11 rotates, it allows the cable position to change continuously during the twisting process. This helps to prevent the cable from being excessively piled up or twisted too tightly at a fixed position, allowing the cable to be twisted more evenly when passing through the drum. This avoids uneven twisting, stress accumulation in certain areas, and damage to the cable during use. The first guide rod 13, guide plate 12, second roller 16, and second guide rod 24 work together to ensure that the cable accurately enters the take-up drum 10, the take-up drum 14, and is wound on the take-up roller 22.
