Description

Technical Field

[0001] This utility model relates to a multifilament tension adjustment device, belonging to the field of cable production technology. Background Technology

[0002] In the cable manufacturing industry, large cross-sectional area conductors are core components of high-voltage power transmission, new energy equipment, and rail transit power supply systems, requiring high conductivity, strong tensile strength, and long-term structural stability. However, uneven tension during the twisting of multiple filaments in the manufacturing process often causes conductor deformation. Severe deformation can lead to excessive tension on individual filaments, resulting in premature breakage, increased gaps between filaments, excessive resistance, and substandard tensile strength, posing serious risks to product quality. Therefore, a tension-adjustable device is needed to fundamentally improve the structural consistency and electrical performance of large cross-sectional area conductors. Utility Model Content

[0003] To address the problems mentioned above in the background art, this utility model provides a multifilament tension adjustment device.

[0004] The technical solution to achieve the purpose of this utility model is as follows: it includes a frame, a guide wheel, a wire spool, an adjustment device and a motor mounted on the frame, and a tension wheel mounted on the adjustment device; the tension wheel is located between the guide wheel and the wire spool, and the position of the tension wheel is adjusted by the adjustment device; the wire core passes through the guide wheel and the tension wheel in sequence and is wound on the wire spool; the wire spool is driven by the motor to realize the winding of the wire core.

[0005] The multifilament tension adjustment device proposed in this application can effectively tension the wire cores after passing through the tension wheel when multiple wire cores need to be processed in parallel. The wire cores can maintain an equal distance and be wound in parallel as they move towards the wire spool. This can effectively solve the problems of wire core deformation and excessive resistance caused by uneven tension during multifilament twisting, and improve the structural consistency and electrical performance of large-square wire cores.

[0006] Further, or optionally, the wire spool can reciprocate horizontally, and the guide wheel and tension wheel are provided with equally spaced partitions for axial region division. The extension line connecting the axial midpoints of the guide wheel and tension wheel intersects the axial region of the wire spool. The partitions serve to divide the wire into regions, separating different wire cores as they pass over the tension wheel, preventing the wire cores from tangling or changing distance during travel.

[0007] Similar to the separator, shallow grooves can also be set on the shafts of the guide wheel and tension wheel to confine the wire core within the shallow grooves for guidance.

[0008] Further or optional, in order to further improve the uniformity among the multiple wire cores, a conductor device is also included, wherein the multiple wire cores are connected in parallel to the guide wheel, tension wheel and wire spool after being processed by the conductor device.

[0009] Further or optionally, in order to pre-divide the distance between the wire cores, the conductor device is a conductor bar, which is fixed on the frame. The conductor bar has conductor holes arranged in parallel. The wire passes through the conductor holes and is connected to the guide wheel. In actual settings, the conductor holes can be set to multiple in a row. When laying the wire, the wire cores are passed through different conductor holes as needed. When the number of conductor holes between different wire cores is inconsistent, the distance between the wire cores can be adjusted by using the separator plate between the guide wheel and the tension wheel.

[0010] Further or optionally, to facilitate the installation of the adjustment device and improve the overall structure of the equipment, the frame includes a base plate and a vertical plate fixed on the base plate; the guide wheel and the adjustment device are mounted on the base plate; the screw spool and the motor are mounted on the vertical plate.

[0011] Further or optionally, in order to adjust the tension of the tension wheel, the adjustment device includes a connecting rod, an angle adjustment plate, and a drive unit; the tension wheel is fixed to the angle adjustment plate via the connecting rod; one side of the angle adjustment plate is hinged to the base plate, and the drive unit is used to control the angle between the angle adjustment plate and the base plate.

[0012] In the diagram, a cylinder is used as the driving unit. During use, the cylinder can adjust the specific angle of the adjustment plate. The angle between the tension wheel, the guide wheel, and the wire disc changes with the specific angle of the angle control plate, and the tension on the wire core changes.

[0013] Furthermore, in order to improve the safety of the production process and prevent the angle adjustment plate from breaking off or exceeding the angle limit, the adjustment device also includes a limiting chain disposed between the free end of the angle adjustment plate and the base plate.

[0014] Further or optional, in order to improve winding efficiency and save equipment placement space, the frame is a symmetrical structure, and the guide rollers, tension rollers, wire spools, limiting devices and motors are all arranged in two symmetrical sets.

[0036] In use, the wire core is passed sequentially through guide wheel 2, tension wheel 3 and wire spool 4. The limiting device 5 adjusts the angle between tension wheel 3 and guide wheel 2 and wire spool 4. The wire core is taut after being pressed down by tension wheel 3. The wire core remains taut during the process from guide wheel 2 to tension wheel 3 and then to wire spool 4, effectively reducing the possibility of the wire core slipping or crossing.

[0037] To make the wire core more evenly wound on the wire spool 4, a reciprocating motion device can be set on the shaft of the wire spool 4. At this time, the wire spool 4 can reciprocate in the horizontal direction, and the wire core is evenly wound along the axial direction.

[0038] To further ensure the uniformity of the core distribution, the guide wheel 2 and the tension wheel 3 are equipped with equal partition plates for axial region division.

[0039] In another embodiment of this application, the above-mentioned device further includes a wire guide device 6. Multiple wire cores are wired and then connected in parallel to the guide wheel 2, tension wheel 3, and wire spool 4 via the wire guide device 6. The wire guide device 6 can be a wire bar, which is fixed to the frame. Wire holes 61 are arranged side-by-side on the wire bar, and the wires pass through the wire holes 61 before being connected to the guide wheel 2. Figure 1 As shown, the wire core passes through the wire hole 61 and is connected to the guide wheel 2, and then enters the tension wheel 3.

[0040] For fixing each part, the connection stability between each part can be improved by using a base plate fixing method. Specifically, the frame 1 includes a base plate 11 and a vertical plate 12 fixed on the base plate 11; the guide wheel 2 and the adjustment device 5 are installed on the base plate 11; the wire spool 4 and the motor are installed on the vertical plate 12.

[0042] In the figure above, the angle adjustment plate 52 is adjusted by a cylinder. In actual installation, a ratchet or other structure capable of graded angle adjustment can also be used to achieve tension adjustment. The adjustment device 5 also includes a limiting chain 53 disposed between the free end of the angle adjustment plate 52 and the base plate 11.

[0043] In another embodiment of this application, the frame 1 has a symmetrical structure, and the guide wheel 2, tension wheel 3, wire spool 4, limiting device 5 and motor are all arranged in two symmetrical sets. This can realize multi-process winding processing and effectively improve work efficiency.
