Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and more specifically, to a linkage-type liquid-cooled cable core covering and forming device. Background Technology

[0002] In high-power transmission scenarios (such as fast charging for new energy vehicles, data center power supply, and rail transit), liquid-cooled cables are widely used due to their excellent heat dissipation performance and current carrying capacity. These cables typically integrate coolant circulation channels around the conductor and require precise insulation, sealing, or functional layers around the cable core to ensure electrical safety and the integrity of the cooling system. Traditional sheathing processes often employ fixed extrusion or winding equipment, which is ill-suited to the complex multi-layered structure and dynamic tension control requirements of liquid-cooled cables. Especially when the sheathing material is a strip-shaped flexible medium, problems such as uneven tension, poor adhesion, and interlayer air gaps can easily occur, affecting cooling efficiency and long-term operational reliability.

[0003] While existing technologies include rotary wrapping devices for cable armoring or shielding layer winding, their structures are mostly conventional rotational with non-adjustable spacing, and lack a comprehensive design for material strip release damping and convenient roller loading and unloading. When applied to wrapping liquid-cooled cable cores, they often cannot achieve coordinated control of wrapping angle, spacing, and tension, resulting in poor molding consistency, low material change efficiency, and weak adaptability.

[0004] Therefore, there is an urgent need for a wrapping and molding device that can be linked and adjusted, dynamically adapted to the cable core shape, and supports rapid maintenance, in order to meet the technical requirements of efficient, high-quality, and flexible manufacturing of liquid-cooled cables.

[0024] The following is a detailed description of a linkage-type liquid-cooled cable core covering and forming device according to an embodiment of the present invention, with reference to the accompanying drawings.

[0025] The linkage-type liquid-cooled cable core coating forming device of the present invention mainly includes a support platform 1, a carrier plate 5, a rotating ring 9, a connecting rod 7, and coating material units 8. The rotating ring 9 is driven by a motor 2 to rotate synchronously, driving multiple coating material units 8 to revolve around the cable core 3. Each coating material unit 8 has three-dimensional adjustable functions: its radial position along the connecting rod 7 is adjustable, its distance relative to the cable core 3 is adjustable, and its material release damping is adjustable, thereby achieving multi-layer, multi-angle, and highly consistent coating forming.

[0026] like Figure 1 As shown, an embodiment of the present invention provides a linkage-type liquid-cooled cable core sheathing and forming device, including a support platform 1 and two carrier plates 5 fixed thereon, and further comprising: Rotating ring 9, two carrier plates 5 are equipped with rotating ring 9 that can rotate synchronously, and multiple connecting rods 7 are fixedly distributed circumferentially between the two rotating ring 9; The coating material unit 8 is slidably mounted on the connecting rod 7. The coating material unit 8 is used for quick assembly and disassembly of the material belt carrier roller 23 and for releasing the material belt wound on the cable core 3 according to the set damping force. The coating material unit 8 can also control and adjust the distance between the material belt carrier roller 23 and the connecting rod 7.

[0027] In this embodiment of the invention, the synchronous rotation of the two rotating rings 9 can drive multiple connecting rods 7 to rotate around the cable core 3 that passes through the middle. The position of the covering material unit 8 and the distance between the material strip carrier roller 23 and the connecting rod 7 can be adjusted as needed, so that the material strip carrier roller 23 and the cable core 3 are fully adapted. Moreover, the covering material unit 8 facilitates the quick assembly and disassembly of the material strip carrier roller 23 and the release of the material strip wrapped around the cable core 3 according to the set damping force, thereby performing a linkage-type covering and forming of the cable core 3 with good quality and high efficiency.

[0028] In summary, this invention achieves dynamic adaptation between the coating material unit 8 and the cable core 3 by driving the circumferentially distributed connecting rods 7 and the adjustable coating material unit 8 to revolve around the cable core 3 through the synchronously rotating rotating ring 9. The coating material unit 8 not only supports the quick assembly and disassembly of the material belt roller 23, but also adjusts its distance from the connecting rod 7 and releases the damping force, thereby taking into account the coating quality, work efficiency and ease of operation in the linkage coating process.

[0029] In one embodiment, such as Figure 1As shown, the installation and driving structure of the rotating ring 9 is as follows: a support ring 4 is fixedly mounted on the carrier plate 5, and the rotating ring 9 is rotatably mounted on the support ring 4. A follower wheel 10 is also fixed on the rotating ring 9. The follower wheel 10 is connected to the main drive wheel 12 via a transmission component 11. Both main drive wheels 12 are fixed on a pivot 13, which is rotatably mounted on the lower part between the two carrier plates 5. A motor 2 for driving the pivot 13 to rotate is also mounted on one of the carrier plates 5. The motor 2 drives the pivot 13 to rotate, and the two main drive wheels 12 transmit power to the two follower wheels 10 via the transmission component 11, thereby enabling the two rotating rings 9 to rotate synchronously. The support ring 4 also enhances the stability of the rotating ring 9's rotation.

[0030] In one optional embodiment, the follower wheel 10 and the main drive wheel 12 can be pulleys or sprockets, and the transmission component 11 can be a belt or chain. The cable core 3 passes through the central axis of the rotating ring 9 and moves at a certain speed. The driving and bearing structures of the cable core 3 are not limited. This invention mainly provides an implementation scheme for the sheathing and molding structure of the cable core 3.

[0031] In a preferred embodiment, the inner wall of the support ring 4 is provided with an annular guide rail and a rolling bearing assembly. The outer edge of the rotating ring 9 slides with the guide rail and is embedded in the inner ring of the bearing, effectively suppressing axial movement and radial offset during rotation and significantly improving rotational stability. The main drive wheel 12 and the follower wheel 10 adopt a synchronous belt pulley structure, and the transmission component 11 is a toothed synchronous belt with a transmission ratio of 1:1, ensuring that the rotation angle error of the two rotating rings 9 is controlled within ±0.3°, achieving high synchronization. The motor 2 is a servo motor with an integrated rotary encoder. The rotation speed and angle are monitored in real time through a closed-loop control system, dynamically matching the moving speed of the cable core 3 (such as the linear speed fed back by the external conveying mechanism), so that the rotation speed of the rotating ring 9 is synchronously adjusted with the tension of the material belt release, avoiding air gaps or tensile deformation of the coating layer caused by speed fluctuations. In addition, the connecting bearing seat of the pivot 13 and the carrier plate 5 is made of self-lubricating composite material, reducing the frequency of maintenance, and the two ends of the pivot 13 are provided with dustproof sealing rings, improving the operational reliability in dusty environments, thereby ensuring rotational synchronization and coating uniformity during the liquid-cooled cable coating process.

[0032] In one embodiment, such as Figure 1-8 As shown, the covering material unit 8 includes an adjusting sleeve 15 slidably sleeved on the connecting rod 7, and a first fastening bolt 14 for locking it on the connecting rod 7 is installed on the adjusting sleeve 15; an adjustable telescopic component is fixed on the side of the adjusting sleeve 15 near the cable core 3, and an installation shaft 18 is rotatably mounted at the end of the telescopic inner rod 21 of the adjustable telescopic component with adjustable damping. A stop plate 22 for blocking the material belt carrier roller 23 is fixed at one end of the installation shaft 18, and a quick-release assembly for abutting and clamping the material belt carrier roller 23 is installed on the side of the stop plate 22 away from the installation shaft 18.

[0033] In one optional embodiment, a first guide 6 is also fixed on the connecting rod 7, and the adjusting sleeve 15 is also slidably connected to the first guide 6, thereby preventing the adjusting sleeve 15 from twisting and improving reliability.

[0034] In one optional embodiment, the adjustable telescopic assembly further includes a telescopic outer cylinder 16 fixed to the adjusting sleeve 15, a telescopic inner rod 21 and a telescopic outer cylinder 16 slidably connected, and a second fastening bolt 17 for locking the telescopic inner rod 21 is also installed on the telescopic outer cylinder 16.

[0035] In one alternative implementation, such as Figure 2-7 As shown, a cavity 31 is provided on the inner side of the mounting shaft 18, and a rotary groove 34 is provided on the outer side of the cavity 31 within the telescopic inner rod 21. A transmission cylinder 36 is provided inside the cavity 31, and a second lead screw 39 is threadedly connected to the transmission cylinder 36. A first knob 19 is fixed to the outer end of the second lead screw 39. Multiple buffer wedges 35 are distributed circumferentially on the outer side of the transmission cylinder 36, and the outer ends of the buffer wedges 35 slide into the rotary groove 34. An elastic element for the buffer wedges 35 to abut against the transmission cylinder 36 and an anti-torsion element to prevent the transmission cylinder 36 from rotating are also provided inside the cavity 31.

[0036] When it is necessary to adjust the damping of the conveyor belt, rotating the first knob 19 drives the second lead screw 39 to rotate. Since the transmission cylinder 36 is restricted from rotation by the anti-torsion component, it moves axially. The tapered portion of the transmission cylinder 36 pushes the buffer wedge 35 outward radially, pressing it against the inner wall of the rotary groove 34, thereby increasing the rotational frictional resistance between the mounting shaft 18 and the telescopic inner rod 21, achieving stepless adjustment of the damping force. When the first knob 19 is rotated in the opposite direction, the elastic element (spring or elastic rope 38) pulls the buffer wedge 35 back to its original position, reducing the damping force.

[0037] Furthermore, the second lead screw 39 is also damped and rotatably connected to the mounting shaft 18 to improve the stability of the second lead screw 39 and prevent it from rotating on its own. The transmission cylinder 36 includes a conical part and a straight cylinder part, and the inner end of the buffer wedge 35 cooperates with the conical part of the transmission cylinder 36. When the second lead screw 39 rotates, the transmission cylinder 36 moves, thereby pushing the buffer wedge 35 toward the rotary groove 34 (the inner wall of the rotary groove 34 is conventionally provided with a friction layer, which is not limited), and the damping force can be adjusted. When the second lead screw 39 is rotated in the opposite direction, the buffer wedge 35 can return to its original position under the elastic force of the elastic element.

[0038] Furthermore, the elastic element includes a side fixing block 37 fixed to the side of the buffer wedge 35. The side fixing block 37 is connected to the side cavity wall of the cavity 31 by a spring / elastic rope 38. The spring / elastic rope 38 can be used to restore the buffer wedge 35 to its original position.

[0039] Furthermore, the anti-torsion component includes a guide cylinder 32 circumferentially distributed and fixed to the outer end of the cavity 31, and a third guide rod 33 slidably disposed on the guide cylinder 32. The other end of the third guide rod 33 is fixedly connected to the end of the transmission cylinder 36. The guide cylinder 32 and the third guide rod 33 are used to prevent the transmission cylinder 36 from twisting, so that the transmission of the second lead screw 39 to the transmission cylinder 36 is reliable.

[0040] In one alternative implementation, such as Figure 8 As shown, the quick-assembly assembly includes a first lead screw 27 rotatably mounted on a stop plate 22. The first lead screw 27 and the mounting shaft 18 are coaxially arranged. A second knob 24 is fixed to the outer end of the first lead screw 27. Multiple pressure plates 25 are distributed circumferentially on the outer side of the first lead screw 27. The inner side of the pressure plate 25 has an inclined structure. Multiple movable seats 30 that slide and cooperate with the pressure plates 25 are threadedly connected to the first lead screw 27. By operating the second knob 24 to rotate the first lead screw 27, the movable seats 30 can push the pressure plates 25 to move stably, thereby using the pressure plates 25 to secure the material belt carrier roller 23, facilitating its quick assembly and disassembly.

[0041] Furthermore, the telescopic inner rod 21 is also equipped with a third fastening bolt 20 for locking and fixing the mounting shaft 18. This allows the mounting shaft 18 to be locked and fixed during quick assembly / disassembly operations, facilitating the quick assembly / disassembly process. The outer side of the pressure plate 25 is parallel to the first lead screw 27, allowing for full adaptation to the material belt carrier roller 23. A first guide rod 28 is fixed to the stop plate 22 corresponding to the pressure plate 25. The end of the first guide rod 28 has a U-shaped head 40 that mates with the pressure plate 25. The end of the pressure plate 25 is also fixed with a second guide rib 41 that slides with the U-shaped head 40. The first guide rod 28 is used to limit the pressure plate 25 relative to the first lead screw 27. 7. Radial movement ensures the reliability of clamping and fixing the material belt carrier roller 23; a tailstock 26 is rotatably mounted on the outer end of the first lead screw 27, and multiple second guide rods 29 parallel to the first lead screw 27 are circumferentially fixed between the tailstock 26 and the stop plate 22. The second guide rods 29 are also slidably connected to the moving seat 30, thereby preventing the moving seat 30 from twisting and improving the reliability of the moving seat 30 in pushing the pressure plate 25 to move; the inner side of the pressure plate 25 is provided with a third guide rib 42, and the outer ring of the moving seat 30 is provided with a guide rail groove 43 slidably connected to the third guide rib 42, thereby making the moving seat 30 and the pressure plate 25 anti-slip cooperation, so that the moving seat 30 can reliably push and pull the pressure plate 25.

[0042] In a preferred embodiment, in the adjustable telescopic assembly, the telescopic outer cylinder 16 is integrally formed from high-strength aerospace aluminum alloy, and its inner wall has a guide groove that forms a zero-clearance sliding fit with the protrusion of the telescopic inner rod 21 to ensure the accuracy of the telescopic stroke.

[0043] In a preferred embodiment, the tapered portion of the buffer wedge 35 is matched with the tapered angle of the transmission cylinder 36 at 15°. Through the fine adjustment of the second lead screw 39, the damping force can be continuously adjusted within a certain range, effectively adapting to the coating requirements of the material strip, and the measured uniformity of the coating layer is improved.

[0044] In a preferred embodiment, in the quick-release assembly, the angle of the inclined inner side of the pressure plate 25 is optimized to 10°, which, together with the V-shaped guide groove of the U-shaped head 40, shortens the installation / removal time of the material belt carrier roller 23; the guide rail groove 43 of the outer ring of the moving seat 30 and the third guide rib 42 of the pressure plate 25 are made of high wear-resistant carbon fiber composite material to ensure clamping reliability.

[0045] The operating procedure for this device is as follows: 1) Insert cable core 3 into the device along the central axis; 2) Adjust and lock the position of each coating material unit 8 on the connecting rod 7 according to the number of coating layers and angle requirements; 3) Adjust the distance between the conveyor roller 23 and the cable core 3 using the adjustable telescopic component; 4) Set the release damping of each material belt using the first knob 19; 5) Insert the conveyor roller 23 into the quick-release assembly and clamp it; 6) Start motor 2 to make rotating ring 9 drive the coating material unit 8 to rotate synchronously, while cable core 3 moves forward at a constant speed to achieve continuous coating.

[0046] The above embodiments of the present invention provide a linkage-type liquid-cooled cable core coating and forming device, the working principle of which is as follows: The motor 2 drives the pivot 13 to rotate, which in turn drives the two main drive wheels 12 fixed on it to rotate. The main drive wheels 12 transmit power to the follower wheel 10 through the transmission component 11, thereby driving the two rotating rings 9 to rotate synchronously on the support ring 4. The multiple connecting rods 7 circumferentially fixed between the rotating rings 9 then revolve around the cable core 3 that passes through its center.

[0047] The covering material unit 8 is slidably mounted on the connecting rod 7 and locked to the adjusting sleeve 15 by the first fastening bolt 14, which can adjust the density of the material strip covering. The adjustable telescopic component consists of a telescopic outer cylinder 16 and a telescopic inner rod 21. The telescopic position is locked by the second fastening bolt 17. The mounting shaft 18 at the end of the telescopic inner rod 21 dampens the rotation of the material strip carrying roller 23. Its damping force is adjusted by the first knob 19 to the second lead screw 39, causing the transmission cylinder 36 to move axially and push the buffer wedge 35 to press against the inner wall of the rotary groove 34. The elastic element 38 cooperates with the side fixing block 37 to achieve reset. The anti-torsion component consists of the guide cylinder 32 and the third guide rod 33. The components restrict the rotation of the transmission cylinder 36 and can adjust the tightness of the material strip wrapping. The quick-release assembly drives the first lead screw 27 to rotate via the second knob 24, causing the moving seat 30 to slide along the second guide rod 29. This pushes the pressure plate 25 to radially clamp or release the material strip carrying roller 23 under the guidance of the U-shaped head 40, the second guide rib 41, the third guide rib 42, and the guide groove 43. The stop plate 22 axially limits the material strip carrying roller 23. Thus, the wrapping material unit 8 can adjust the distance from the cable core 3 as needed and release the material strip with constant damping, achieving efficient, stable, and high-quality linkage wrapping molding of the moving cable core 3.

[0048] In summary, this device achieves efficient, stable, and high-quality coating and molding of liquid-cooled cable cores through linkage rotation and a multi-dimensional adjustable coating structure, while also having the functions of adjusting coating density and tightness and quick assembly and disassembly of the material strip carrying roller.
