Description

Technical Field

[0001] The utility model relates to the technical field related to cables, in particular to a multi-core cable twisting device. Background Art

[0002] Cables are important carriers for transmitting electrical energy, signals, and data. In the power sector, they transmit electricity generated by power plants to various power-consuming areas, providing a stable power supply for industrial production, commercial activities, and residential life.

Cables are also widely used in many industries, including transportation, petrochemicals, and aerospace. Early cables mainly used natural materials such as rubber and silk as insulation layers and sheaths. These materials have limited performance, resulting in low transmission capacity and short lifespan. With the advancement of technology, synthetic materials such as polyethylene and polyvinyl chloride have gradually been used in cable manufacturing. These materials have better insulation properties, mechanical strength, and corrosion resistance, greatly improving the quality and reliability of cables. In recent years, with the continuous improvement of cable performance requirements, new materials and technologies have continued to emerge. For example, cables made of superconducting materials can achieve high-capacity and low-loss power transmission. Optical fiber cables have great advantages in the communications field, with characteristics such as high speed, large capacity, and anti-interference.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model provides a technical solution: a multi-core cable twisting device, comprising an operating table 1, a silicone pad 2 is fixedly connected to the bottom of the operating table 1, an adjustable bracket 3 is fixedly connected to the upper surface of one end of the operating table 1, a fixed block 4 is fixedly connected to the upper surface of the other end of the operating table 1, an adjustment device 5 is provided on the upper surface of the operating table 1, a guide device 6 is provided on the upper surface of the adjustable bracket 3, a support frame 7 is fixedly connected to the upper surface of the operating table 1, a tightening wheel 8 is rotatably connected to the inner wall of the support frame 7, and a sealing device 9 is provided on the upper surface of the fixed block 4;

[0025] The adjusting device 5 includes a fixing seat 501, an adjusting rod 502, a threaded hole 503, a clamping hole 504, a spring 505, a limit block 506, a clamping block 507, a limit hole 508 and a bolt 509. The upper surface of the operating table 1 is fixedly connected to the fixing seat 501, and the inner wall of the fixing seat 501 is slidably connected to the adjusting rod 502. The surface of the fixing seat 501 is provided with a threaded hole 503, and the inner wall of the adjusting rod 502 is provided with a clamping hole 504. The inner wall surface of the clamping hole 504 is fixedly connected to the spring 505. One end of 505 is fixedly connected to a limit block 506, and one end surface of the limit block 506 is fixedly connected to a clamping block 507. A limit hole 508 is provided on the inner wall surface of the fixing seat 501, and a bolt 509 is threadedly connected to the inner wall surface of the threaded hole 503. By setting the adjustment device 5, the height of the stranding can be adjusted according to different types of multi-core cables. The operator applies external force to the adjustment rod 502, and the adjustment rod 502 slides in the inner wall of the fixing seat 501 to adjust the position of a specific part of the device. During the adjustment process, the spring 505 in the card hole 504 is in a compressible and stretchable state. When the adjustment rod 502 moves to the desired position, the spring 505 pushes the limit block 506, so that the card block 507 extends outward. If the card block 507 corresponds to the position of the limit hole 508 on the inner wall surface of the fixing seat 501 at this time, the card block 507 will be stuck in the limit hole 508 under the action of the spring 505, thereby achieving the initial fixation of the adjustment rod 502. In order to further ensure the stable position of the adjustment rod 502, the operator The operator screws the bolt 509 into the threaded hole 503. During the screwing process, the end of the bolt 509 gradually approaches the surface of the adjusting rod 502 until it is tightly against the adjusting rod 502, thereby applying a stable pressure on the adjusting rod 502 to prevent it from accidentally moving during operation. In this way, through the cooperation of the block 507 and the limiting hole 508 and the tightening action of the bolt 509, the adjusting device 5 can firmly fix the adjusting rod 502 in the desired position to meet the production requirements of different types of multi-core cables.

[0026] Furthermore, multiple groups of silicone pads 2 are provided at the bottom of the operating table 1, and are symmetrically arranged at the four corners of the operating table 1 with respect to the longitudinal center axis of the operating table 1. By setting the silicone pads 2, the operating table 1 can remain stable during operation. No matter what kind of vibration or external force the multi-core cable twisting device generates during operation, the silicone pads 2 at the four corners can evenly disperse the force, ensuring that the operating table 1 will not shake or displace easily, thereby ensuring the accuracy and stability of the entire twisting process.

[0027] Furthermore, the outer wall size of the adjusting rod 502 is consistent with the size of the groove on the inner wall of the fixing seat 501, and there are multiple groups of threaded holes 503 on the surface of the fixing seat 501, and the threaded holes 503 on the surface of the fixing seat 501 correspond to the holes opened on the surface of the adjusting rod 502. Through the setting of the fixing seat 501, the adjusting rod 502 and the threaded holes 503, the matching of the sizes ensures the stability and accuracy of the sliding of the adjusting rod 502 in the fixing seat 501. When adjusting the position, there will be no shaking or offset, so that the operator can accurately adjust the adjustment rod 502 to the desired position to meet the production requirements of different types of multi-core cables. Multiple groups of threaded holes 503 provide multiple fixed position options for the adjusting rod 502. When producing multi-core cables of different types, the adjusting rod 502 can be fixed at different heights or positions according to specific needs, which greatly improves the flexibility and adaptability of the device.

[0028] Furthermore, the limit block 506 cooperates with the block 507 through the spring 505 to form a telescopic structure. The outer wall size of the block 507 matches the inner wall size of the limit hole 508. Through the setting of the spring 505, the block 507 and the limit hole 508, when the adjustment rod 502 moves to the appropriate position, the block 507 can be quickly inserted into the limit hole 508 under the action of the spring 505, thereby realizing the initial positioning of the adjustment rod 502. This quick positioning function not only improves work efficiency, but also reduces the tedious operations of the operator during the adjustment process. The size matching enables the block 507 to be tightly combined after being inserted into the limit hole 508, providing a firm fixation for the adjustment rod 502.

[0029] Furthermore, there are multiple groups of limiting holes 508 on the inner wall of the fixing seat 501, and the positions of the limiting holes 508 correspond to the positions of the blocking blocks 507. Through the setting of the limiting holes 508, the setting of multiple groups of limiting holes 508 makes it more convenient and quick for the operator to adjust the position of the adjusting rod 502. There is no need to perform complicated measurements and calculations. It is only necessary to select the appropriate limiting holes 508 according to the actual situation, which greatly reduces the difficulty of operation and improves work efficiency.

[0030] Furthermore, the guide device 6 includes a first motor 601, a rotating shaft 602, a connecting cylinder 603, a fixed rod 604, a bobbin 605, a first guide plate 606, a guide wheel 607, a second guide plate 608 and a branching hole 609. The upper surface of the adjustable bracket 3 is fixedly connected to the first motor 601, one end of the first motor 601 is fixedly connected to the rotating shaft 602, one end of the rotating shaft 602 is fixedly connected to the connecting cylinder 603, one end of the connecting cylinder 603 is fixedly connected to the fixing rod 604 above, and the fixing rod 604 is fixedly connected to the bobbin 605 above. The upper surface of the adjusting device 5 is provided with a first guide plate 606, a guide wheel 607, a second guide plate 608 and a branching hole 609. A guide disc 606 is provided, wherein the interior of the first guide disc 606 is fixedly connected to a guide wheel 607, and the outer wall surface of the end of the connecting cylinder 603 is fixedly connected to a second guide disc 608, and a branching hole 609 is provided on the surface of the second guide disc 608. The first guide disc 606 is fixedly connected to the adjusting rod 502. Through the setting of the guide device 6, when the multi-core cable twisting device is started, the first motor 601 starts to run, the first motor 601 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the connecting cylinder 603 to rotate, and the fixed rod 604 and the wire drum 605 on the connecting cylinder 603 also rotate together, and the wire drum 605 rotates together. The cable wound on the cylinder 605 is gradually released under the action of rotation. The released cable first passes through the first guide disk 606. The guide wheel 607 inside the first guide disk 606 plays a role of guidance and preliminary positioning to ensure that the cable can accurately enter the subsequent twisting process. The guide wheel 607 can be appropriately adjusted according to the thickness and movement direction of the cable to ensure the smoothness of the cable during the guiding process. Then, the cable passes through the second guide disk 608 on the outer wall surface of the end of the connecting cylinder 603. The branching hole 609 on the second guide disk 608 further combs and positions multiple cables. Different cables enter the twisting area through the corresponding branching holes 609, ensuring that each cable is accurately positioned during the twisting process to avoid entanglement, interlacing and confusion. Since the first guide disk 606 is fixedly connected to the adjusting rod 502, when the position of the guide device 6 needs to be adjusted, it can be achieved by operating the adjusting rod 502 through the adjusting device 5. For example, when it is necessary to adapt to the production of multi-core cables of different models, the height or angle of the adjusting rod 502 can be adjusted, thereby driving the first guide disk 606 to change position to ensure that the guide device 6 can always provide accurate guidance and positioning for cables of different specifications.

[0031] Furthermore, multiple groups of guide wheels 607 are provided inside the first guide disk 606, and multiple groups of branching holes 609 are provided in a ring at equal intervals around the center of the second guide disk 608. Through the provision of the guide wheels 607 and the branching holes 609, multiple groups of guide wheels 607 can guide and support the cables from multiple directions. When the cables pass through the first guide disk 606, multiple groups of guide wheels 607 work together to ensure that the cables maintain a stable direction of movement before entering the twisting process, avoiding deviation or shaking, thereby improving the accuracy and stability of the entire twisting process. Multiple groups of branching holes 609 can accurately branch and position multiple cables. During the twisting process, each cable can enter the twisting area through the corresponding branching hole 609, ensuring that the spacing between the cables is uniform and the twisting effect is tighter and more regular.

[0032] Furthermore, the sealing device 9 includes a second motor 901, a transmission shaft 902, a gear 903, a crawler 904, a roller 905, a film 906 and a connecting plate 907. The upper surface of the fixed block 4 is fixedly connected to the second motor 901, one end of the second motor 901 is fixedly connected to the transmission shaft 902, one end of the transmission shaft 902 is fixedly connected to the gear 903, the outer wall surface of the gear 903 is affixed to the crawler 904, the inner wall of the other end of the crawler 904 is affixed to the roller 905, the outer wall surface of the roller 905 is fixedly connected to the film 906, and one end surface of the roller 905 is rotatably connected to the connecting plate 907. Through the setting of the sealing device 9, when the twisted multi-core cable needs to be sealed, the second motor 901 is started, the second motor 901 drives the transmission shaft 902 to rotate, and the transmission shaft 902 then drives the gear 903 at one end to rotate, and the rotation of the gear 903 The drive belt 904 that is in contact with its outer wall surface is used for transmission. As the belt 904 moves, the belt 904 drives the roller 905 that is in contact with the inner wall at the other end to rotate, and the film 906 fixedly connected to the outer wall surface of the roller 905 also rotates accordingly. When the twisted multi-core cable passes under the film 906, the sealing material on the film 906 is evenly covered on the cable surface. The connecting plate 907 that is rotatably connected to the surface of one end of the roller 905 plays the role of supporting and stabilizing the roller 905. During the rotation of the roller 905, the connecting plate 907 ensures that the axis rotation of the roller 905 remains stable to prevent shaking or deviation, thereby ensuring that the sealing material can be accurately and evenly covered on the cable surface. Through the precise control of the second motor 901, the rotation speed of the roller 905 can be adjusted, and then the covering speed and thickness of the sealing material can be controlled to meet the sealing requirements of multi-core cables of different specifications.

[0033] Furthermore, multiple groups of film rolls 906 are arranged on the surface of the roller 905, and are distributed at equal intervals around the central axis of the roller 905. Through the arrangement of the film rolls 906, the equal-interval distribution can ensure that the sealing material covers the cable surface more evenly, avoiding the situation where the cable is locally too thick or too thin, thereby improving the quality and reliability of the sealing layer.

[0034] Working principle: First, the height of the twisted cable can be adjusted according to different types of multi-core cables. The operator applies external force to the adjusting rod 502, and the adjusting rod 502 slides in the inner wall of the fixing seat 501 to adjust the position of a specific part of the device. During the adjustment process, the spring 505 in the clamping hole 504 is in a compressible and stretchable state. When the adjusting rod 502 moves to the desired position, the spring 505 pushes the limit block 506, so that the clamping block 507 extends outward. If the clamping block 507 corresponds to the position of the limit hole 508 on the inner wall surface of the fixing seat 501 at this time, the clamping block 507 will be clamped into the limit hole 508 under the action of the spring 505, thereby achieving preliminary fixation of the adjusting rod 502. In order to further ensure that the adjusting rod 50 2 is stable, the operator screws the bolt 509 into the threaded hole 503. During the screwing process, the end of the bolt 509 gradually approaches the surface of the adjusting rod 502 until it is tightly against the adjusting rod 502, thereby applying a stable pressure to the adjusting rod 5502 to prevent it from accidentally moving during operation. In this way, through the cooperation of the block 507 and the limiting hole 508 and the tightening effect of the bolt 509, the adjusting device 5 can firmly fix the adjusting rod 502 in the required position to meet the production requirements of different types of multi-core cables. The silicone pad 2 can keep the operating table 1 stable during operation. No matter what kind of vibration or external force the multi-core cable twisting device generates during operation, the silicone pads 2 at the four corners can evenly disperse the force to ensure operation The workbench 1 will not shake or move easily, thereby ensuring the accuracy and stability of the entire twisting process. When the multi-core cable twisting device is started, the first motor 601 starts to run, and the first motor 601 drives the rotating shaft 602 to rotate, and the rotating shaft 602 then drives the connecting cylinder 603 to rotate, and the fixing rod 604 and the wire drum 605 on the connecting cylinder 603 also rotate together. The cable wound on the wire drum 605 is gradually released under the action of rotation, and the released cable first passes through the first guide disk 606. The guide wheel 607 inside the first guide disk 606 plays a role of guidance and preliminary positioning to ensure that the cable can accurately enter the subsequent twisting process. The guide wheel 607 can be appropriately adjusted according to the thickness and movement direction of the cable to ensure that the cable can enter the subsequent twisting process accurately. To ensure the smoothness of the cable during the guiding process, the cable then passes through the second guide disc 608 on the outer wall surface of the end of the connecting tube 603. The branching holes 609 on the second guide disc 608 further sort out and position the multiple cables. Different cables enter the twisting area through the corresponding branching holes 609 to ensure that the position of each cable is accurate during the twisting process to avoid entanglement, interlacing and confusion. Since the first guide disc 606 is fixedly connected to the adjusting rod 502, when the position of the guide device 6 needs to be adjusted, it can be achieved by operating the adjusting rod 502 through the adjusting device 5. For example, when it is necessary to adapt to the production of multi-core cables of different models, the height or angle of the adjusting rod 502 can be adjusted, thereby driving the first guide disc 606 to change its position.To ensure that the guide device 6 can always provide accurate guidance and positioning for cables of different specifications, when it is necessary to seal the twisted multi-core cable, the second motor 901 is started, and the second motor 901 drives the transmission shaft 902 to rotate, and the transmission shaft 902 then drives the gear 903 at one end to rotate, and the rotation of the gear 903 drives the crawler 904 that fits its outer wall surface to transmit. As the crawler 904 moves, the crawler 904 drives the roller 905 that fits the inner wall of the other end to rotate, and the film 906 fixedly connected to the outer wall surface of the roller 905 also rotates together. When the twisted multi-core cable passes under the film 906, the sealing material on the film 906 is evenly covered on the cable surface. The connecting plate 907 connected to the surface of one end of the roller 905 plays a role in supporting and stabilizing the roller 905. During the rotation of the roller 905, the connecting plate 907 ensures that the axis rotation of the roller 905 remains stable to prevent shaking or deviation, thereby ensuring that the sealing material can be accurately and evenly covered on the cable surface. Through the precise control of the second motor 901, the rotation speed of the roller 905 can be adjusted, and the covering speed and thickness of the sealing material can be controlled to meet the sealing requirements of multi-core cables of different specifications. The model of the first motor 601 is YE2-132S-4, and the model of the second motor 901 is Y315S-2. This completes the use process of a multi-core cable twisting device.
