Description

Technical Field

[0001] This application relates to the field of cable manufacturing technology, and in particular to a cable stranding device. Background Technology

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors. As an important carrier of power transmission, cables are widely used in various fields. In the cable production process, stranding is an important process that directly affects the quality and performance of the cable.

[0003] During cable manufacturing, the wire unwinding spool typically unwinds multiple wires at once. The outer surface of the stranded wires inevitably accumulates dust and some large particles. If not cleaned, these particles can scratch the wires and the stranding machine during the stranding process. Furthermore, if dust gets trapped inside the cable, it can affect the quality of the produced cable. Current cable manufacturing stranding equipment typically uses brushes that rotate around the cable to clean the wires.

[0004] The existing technical solutions mentioned above have the following drawbacks: the existing devices rely on manual adjustment of the bristle spacing, which is cumbersome. If the bristle spacing is not adjusted to a suitable value according to the wire diameter, it may lead to incomplete cleaning or damage to the cable, resulting in reduced product quality. Utility Model Content

[0005] This application provides a cable stranding device to facilitate adjusting the brush spacing according to the wire diameter and ensure product quality.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A cable production stranding device includes a base plate, on which a first support frame and a second support frame are fixedly connected. A rotating shaft is rotatably connected to both the first and second support frames. A sub-coil is rotatably mounted on the first support frame. A motor is mounted on the base plate, and the output shaft of the motor is connected to a first pulley. A second pulley is connected to the rotating shaft, and a belt is wound around both the first and second pulleys. A threading reel is rotatably mounted on the second support frame. A mounting frame is fixedly connected to the rotating shaft. Multiple cleaning cylinders are spaced apart on the mounting frame. Each cleaning cylinder includes an outer cylinder fixed to the mounting frame, an inner cylinder rotatably mounted inside the outer cylinder, a brush block passing through and slidably mounted on the inner cylinder, a brush plate connected to the brush block, and multiple brush bristles on the brush plate. An adjustment component is mounted on the inner cylinder.

[0008] The adjustment assembly includes an adjustment ring integrally formed on the inner cylinder, an adjustment block passing through and slidably disposed on the adjustment ring, multiple adjustment blocks being spaced apart, a limit groove being formed on the adjustment block, a limit ring groove being formed on the adjustment ring, a first elastic element being sleeved on the adjustment ring, the first elastic element being embedded in the limit groove and the limit ring groove, and an adjustment rod being fixedly connected to the adjustment block, the adjustment rod being fixedly connected to the brush block.

[0009] By adopting the above technical solution, the adjusting block can drive multiple adjusting rods to move between the inner and outer cylinders, thereby moving the brush block and brush bristles. This allows for adjustment of the distance between the brush block and brush bristles and the peripheral wall of the wire core according to the wire core diameter. It also facilitates adjustment of the brush bristle spacing based on the wire diameter, ensuring the stability of the cleaning effect of the brush bristles on the wire core surface, reducing the risk of cable quality degradation due to impurities adhering to the wire core surface, and thus ensuring cable quality and product quality.

[0010] Optionally, a synchronizing ring is fitted onto the inner cylinder, the synchronizing ring is rotatably connected to the inner cylinder, the synchronizing ring has synchronizing holes, and multiple synchronizing holes are spaced apart, with multiple adjusting rods passing through and slidingly connected to the multiple synchronizing holes respectively.

[0011] By adopting the above technical solution, when the adjusting rod moves under the action of the adjusting block, the adjusting rod pushes the inner wall of the synchronizing hole. At this time, the synchronizing ring rotates on the outer wall of the inner cylinder. When the synchronizing ring rotates, the synchronizing hole can push multiple adjusting rods to move closer to or further away from the outer wall of the inner cylinder at the same time, and can ensure that multiple adjusting rods are at the same distance from the outer wall of the inner cylinder. This ensures that multiple sets of brush bristles set on the brush block are at the same distance from the outer wall of the wire core, ensuring the cleaning effect of the brush bristles on the wire core, reducing the risk of cable quality degradation caused by impurities adhering to the surface of the wire core, and ensuring cable quality and product quality.

[0012] Optionally, a third support frame is fixedly connected to the base plate, a fixed cylinder is rotatably mounted on the third support frame, an internal gear ring is fixedly connected to the fixed cylinder, and an external gear ring that meshes with the internal gear ring is fixedly connected to the inner cylinder.

[0013] By adopting the above technical solution, the outer toothed ring connected to the inner cylinder of the cleaning cylinder moves along the inner wall of the inner toothed ring. At this time, the outer toothed ring meshes with the inner toothed ring, which can drive the outer toothed ring and the inner cylinder to rotate in the outer cylinder. The rotating inner cylinder can drive the bristles to rotate against the peripheral wall of the wire core, improve the cleaning effect of the bristles on the surface of the wire core, reduce the risk of cable quality degradation caused by impurities adhering to the surface of the wire core, and ensure cable quality and product quality.

[0014] Optionally, the brush block is spirally arranged along the circumferential wall of the inner cylinder.

[0015] By adopting the above technical solution, the brush blocks spirally arranged along the inner cylinder wall can form a continuous sweeping path when the inner cylinder rotates, covering the outer wall of the wire core, reducing the cleaning blind spots when the brush bristles clean the wire core wall, reducing the risk of cable quality degradation caused by impurities adhering to the wire core surface, and ensuring cable quality and product quality.

[0016] Optionally, the pitch of the spirally arranged brush block near the first support frame is greater than the pitch of the brush block near the third support frame.

[0017] By adopting the above technical solution, when the wire core enters the cleaning cylinder, it first contacts the section with sparser bristles. As the wire core moves towards the section with denser bristles, the axial resistance encountered by the wire core gradually increases. This reduces the vibration or jamming of the wire core during movement caused by a sudden increase in resistance, ensuring stable delivery of the wire core on the stranding device, reducing the risk of cable quality degradation due to impurities adhering to the wire core surface, and thus ensuring cable quality and product quality.

[0018] Optionally, the brush block is provided with an adjustment groove, the brush plate is slidably disposed in the adjustment groove, a second elastic member is provided in the adjustment groove, the two ends of the second elastic member are respectively connected to the bottom of the adjustment groove and the brush plate, and a baffle for blocking the brush plate is fixedly connected in the adjustment groove.

[0019] By adopting the above technical solution, the elastic force of the second elastic element can push the brush plate to move the bristles so that the bristles adhere to the outer wall of the wire core. When the bristles wear down and become shorter, the elastic force of the second elastic element can push the brush plate out of the brush block, ensuring that the bristles can adhere to the peripheral wall of the wire core after wear. This reduces the risk of reduced cleaning effect due to untimely maintenance and bristle wear, ensures the cleaning effect of the bristles on the wire core, reduces the risk of cable quality degradation due to impurities adhering to the surface of the wire core, and ensures cable quality and product quality.

[0020] Optionally, the brush plate located near the first support frame of the inner cylinder is provided with steel wires for cleaning large particles of material adhering to the core, and multiple steel wires are provided at intervals.

[0021] By adopting the above technical solutions, steel wire can improve the cleaning effect on large particles attached to the wire core, reduce the risk of cable quality degradation caused by impurities attached to the wire core surface, and ensure cable quality and product quality.

[0022] Optionally, an adjusting roller is rotatably provided at one end of the adjusting block.

[0023] By adopting the above technical solution, the adjusting roller can reduce the wear caused by the friction of the adjusting block on the peripheral wall of the wire core.

[0024] In summary, this application has the following technical effects:

[0025] 1. By setting an adjusting ring, adjusting block, first elastic element, adjusting rod and brush block, the distance between the brush block and the brush bristles and the peripheral wall of the wire core can be adjusted according to the diameter of the wire core. This makes it easy to adjust the bristle spacing according to the wire diameter, ensures the stability of the cleaning effect of the brush bristles on the surface of the wire core, reduces the risk of cable quality degradation caused by impurities adhering to the surface of the wire core, and ensures cable quality and product quality.

[0026] 2. By setting a synchronization ring, it is possible to ensure that multiple adjusting rods are at the same distance from the outer wall of the inner cylinder, so that multiple sets of brush bristles set on the brush block are at the same distance from the outer wall of the wire core. This ensures the cleaning effect of the brush bristles on the wire core, reduces the risk of cable quality degradation caused by impurities adhering to the wire core surface, and ensures cable quality and product quality.

[0027] 3. By incorporating steel wires, the cleaning effect on large particles adhering to the wire core is improved, reducing the risk of cable quality degradation caused by impurities adhering to the wire core surface, thus ensuring cable quality and product quality. Attached Figure Description

The other end of the adjustment block 82 passes through the outer wall of the adjustment ring 81 and is provided with a limiting groove 821. A limiting ring groove 83 is provided on the outer wall of the adjustment ring 81. A first elastic element 84 is sleeved on the outer wall of the adjustment ring 81. In this embodiment, the first elastic element 84 is a spring and is connected end to end in a ring shape. The first elastic element 84 is embedded in the limiting ring groove 83 and the limiting groove 821.

[0036] Reference Figure 2 and Figure 3An adjusting rod 85 is connected to one end of an adjusting block 82 extending from an adjusting ring 81. The adjusting rod 85 is positioned along the length of the inner cylinder 72 and between the outer cylinder 71 and the inner cylinder 72. Both ends of the adjusting rod 85 are connected to corresponding adjusting blocks 82 on the two adjusting rings 81. The ends of the adjusting rod 85 are welded to the ends of the adjusting blocks 82 extending from the adjusting rings 81. A brush block 74 is threaded through the circumferential wall of the inner cylinder 72. The brush block 74 is spirally arranged along the circumferential wall of the inner cylinder 72. The pitch of the section of block 74 near the first support frame 11 is greater than the pitch of the section of brush block 74 near the third support frame 13. One end of brush block 74 is located between the inner cylinder 72 and the outer cylinder 71 and is welded to the adjusting rod 85 near it. One end of brush block 74 is located inside the inner cylinder 72 and is connected to a brush plate 75. The brush plate 75 is provided with bristles 76. The section of brush plate 75 located in the inner cylinder 72 near the first support frame 11 is provided with steel wire for cleaning large particles of material attached to the core.

[0037] Reference Figure 3 The brush block 74 has an adjustment groove 741 on one end face of the inner side of the inner cylinder 72. The brush plate 75 is slidably disposed in the adjustment groove 741. A second elastic element 742 is disposed in the adjustment groove 741. In this embodiment, the second elastic element 742 is a spring. One end of the second elastic element 742 is welded to the bottom of the groove of the adjustment groove 741, and the other end is welded to the brush plate 75. A baffle for blocking the brush plate 75 is welded at the opening of the groove of the adjustment groove 741.

[0038] Reference Figure 2 A synchronizing ring 86 is fitted on the outer wall of the inner cylinder 72. The synchronizing ring 86 is rotatably connected to the inner cylinder 72. Two synchronizing rings 86 are spaced apart along the length of the inner cylinder 72. The synchronizing ring 86 has a synchronizing hole 87. The synchronizing hole 87 is a strip-shaped hole with an arc-shaped opening. One end of the synchronizing hole 87 is located near the inner cylinder 72 of the synchronizing ring 86, and the other end of the synchronizing hole 87 is located near the outer cylinder 71 of the synchronizing ring 86. Multiple synchronizing holes 87 are spaced apart and correspond one-to-one with multiple adjusting rods 85. The adjusting rods 85 pass through and slide in the synchronizing holes 87.

[0039] When using this stranding device, multiple wire cores are passed through multiple cleaning cylinders 7 and threading holes along the length of the rotating shaft 2. The motor 14 is started to drive the rotating shaft 2 to rotate. After the wire cores are cleaned in the cleaning cylinders, they are stranded into a cable after passing through multiple threading holes in the threading reel 4. When the wire cores pass through the cleaning cylinders 7, they push the adjusting blocks 82 on the adjusting rings 81 to move outward from the adjusting rings 81. The elastic force of the first elastic element 84 can push one end of the adjusting block 82 to fit against the peripheral wall of the wire core. The multiple adjusting blocks 82 on the two adjusting rings 81 can drive multiple adjusting rods 85 to move between the inner cylinder 72 and the outer cylinder 71, thereby moving the brush blocks 74 and brush bristles 76. This allows the distance between the brush blocks 74 and brush bristles 76 and the peripheral wall of the wire core to be adjusted according to the diameter of the wire core. This facilitates the adjustment of the spacing of the brush bristles 76 according to the wire diameter, ensuring the stability of the cleaning effect of the brush bristles 76 on the surface of the wire core, reducing the risk of cable quality degradation due to impurities adhering to the surface of the wire core, and ensuring cable quality and product quality.

[0040] When the rotating shaft 2 drives the mounting bracket 6 to rotate, the outer gear ring 73 connected to the inner cylinder 72 of the cleaning cylinder 7 moves along the inner wall of the inner gear ring 51. At this time, the outer gear ring 73 meshes with the inner gear ring 51, which can drive the outer gear ring 73 and the inner cylinder 72 to rotate in the outer cylinder 71. The rotating inner cylinder 72 can drive the bristles 76 to rotate against the peripheral wall of the wire core, improving the cleaning effect of the bristles 76 on the surface of the wire core. The brush blocks 74 spirally arranged along the peripheral wall of the inner cylinder 72 can make the bristles 76 form a continuous sweeping path when the inner cylinder 72 rotates, covering the outer wall of the wire core and reducing the cleaning blind spots when the bristles 76 clean the peripheral wall of the wire core. The pitch of the section of brush block 74 near the first support frame 11 is greater than the pitch of the section of brush block 74 near the third support frame 13. This allows the wire core to first contact the section of brush bristles 76 where they are sparser when it enters the cleaning cylinder 7. As the wire core moves toward the section of brush bristles 76 where they are denser, the axial resistance experienced by the wire core gradually increases. This reduces the vibration or jamming of the wire core during movement caused by a sudden increase in resistance, ensuring stable delivery of the wire core on the stranding device. The steel wire can improve the cleaning effect on large particles attached to the wire core, reducing the risk of cable quality degradation caused by impurities attached to the wire core surface, thus ensuring cable quality and product quality.

[0041] When using this stranding device, the adjusting rod 85 passes through the synchronizing hole 87 on the synchronizing ring 86. When the adjusting rod 85 moves under the action of the adjusting block 82, it pushes the inner wall of the synchronizing hole 87. At this time, the synchronizing ring 86 rotates on the outer wall of the inner cylinder 72. When the synchronizing ring 86 rotates, the synchronizing hole 87 can push multiple adjusting rods 85 to simultaneously approach or move away from the outer wall of the inner cylinder 72, and can ensure that multiple adjusting rods 85 are at the same distance from the outer wall of the inner cylinder 72. This ensures that multiple sets of brush bristles 76 set on the brush block 74 are at the same distance from the outer wall of the wire core, ensuring the cleaning effect of the brush bristles 76 on the wire core, reducing the risk of cable quality degradation caused by impurities adhering to the surface of the wire core, and ensuring cable quality and product quality.

[0042] When using this stranding device, the elastic force of the second elastic element 742 can push the brush plate 75 to move the bristles 76 so that the bristles 76 fit against the outer wall of the wire core. When the bristles 76 wear and become shorter, the elastic force of the second elastic element 742 can push the brush plate 75 out of the brush block 74, ensuring that the bristles 76 can fit against the peripheral wall of the wire core after wear, reducing the risk of reduced cleaning effect due to untimely maintenance, ensuring the cleaning effect of the bristles 76 on the wire core, reducing the risk of cable quality degradation due to impurities adhering to the surface of the wire core, ensuring cable quality, and ensuring product quality.
