A wire laying device for a stranded wire

Abstract

This utility model discloses a wire feeding device for stranding, employing a feeding drum, a rotating drum, and a tension adjusting mechanism. The rotating drum and tension adjusting mechanism guide the wire to be stranded to the stranding equipment. The stranding equipment pulls the wire off the feeding drum and releases it, driving the tension adjusting mechanism and the rotating drum to rotate. This ensures that the rotating drum and tension adjusting mechanism continuously guide the wire to the stranding equipment, eliminating the need for a drive component to rotate the feeding device, reducing production costs and avoiding sudden changes in wire tension. The tension adjusting mechanism can significantly adjust the wire tension before feeding and stranding, and can further adjust the wire tension in real time during the feeding and stranding process, preventing excessive or insufficient wire tension from causing breakage, deformation, or tangling and accumulation, thus improving the stability of the feeding process and ensuring the quality of the finished stranded wire.

Description

Technical Field

[0001] This utility model relates to the technology of laying out metal cables such as copper and aluminum, and in particular to a laying out device for stranded wires. Background Technology

[0002] A stranding machine is a winding device used to produce wires, cables, and other cables by twisting multiple strands together to form a single cable. The stranding principle of a stranding machine is as follows: multiple strands of wire are released by the unwinding device, and these strands enter the stranding bow through the main shaft. The rotating bow twists the multiple strands together, and finally, the stranded wire is wound into the take-up device by the guide roller.

[0003] Existing stranding machines use a wire-laying device where the wire to be stranded is wound onto the wire-laying frame. A drive unit rotates the wire-laying frame, which in turn pulls the wire to release it. When multiple strands of wire or cable need to be stranded, a high-power drive unit is often required to release the multiple strands from the wire-laying frame. Sometimes, a separate wire-laying frame and drive unit are needed for each type of wire, releasing different types of wire separately, which is not conducive to reducing production costs. Secondly, if the speed at which the drive unit releases the wire does not match the speed at which the stranding machine strands the wire, sudden changes in wire tension can easily occur, affecting the quality of the finished stranded wire.

[0004] Existing wire tensioning techniques suffer from problems such as excessive or insufficient wire tension. Excessive tension can easily cause wire breakage or deformation, while insufficient tension can cause the wire to become messy or piled up. Therefore, using a tension adjustment mechanism in the wire tensioning process is an important means to ensure the quality of the finished stranded wire. Summary of the Invention

[0005] The main objective of this invention is to provide a wire feeding device for stranded wires to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes a wire feeding device for stranding, including a wire feeding device and a base; The wire feeding device is mounted on the base and includes a support base, a wire feeding drum, a rotating drum, and a tension adjustment mechanism. The wire feeding drum is connected to the support base. The rotating drum has a wire passing groove that passes through the rotating drum and is sleeved on the outside of the wire feeding drum and rotatably mounted on the support base. The tension adjustment mechanism is mounted on the rotating drum. The tension adjustment mechanism includes a connecting cylinder, an adjusting cylinder, a connecting rod, a wire guide cylinder, a support block, and an elastic element. The connecting cylinder is mounted on the rotating cylinder, and part of the adjusting cylinder is mounted inside the connecting cylinder. The relative position of the adjusting cylinder and the connecting cylinder is adjustable. The connecting rod is connected to the wire guide cylinder, and part of the connecting rod is slidably sleeved inside the adjusting cylinder. The support block is mounted inside the adjusting cylinder, and both ends of the elastic element are connected to the support block and the connecting rod, respectively. The wire is wound on the wire feeding drum and can pass through the wire guide groove and the wire guide drum to extend to the stranding equipment, and can be pulled by the stranding equipment to drive the tension adjustment mechanism and the drum to rotate.

[0007] In an optional embodiment, a limiting block is fixedly provided on the outer side of the connecting rod, and the limiting block abuts against the adjusting cylinder in the direction in which the connecting rod slides relative to the adjusting cylinder.

[0008] In an optional embodiment, the connecting cylinder and the adjusting cylinder are connected by a first threaded assembly, and the adjusting cylinder can adjust its relative position with the connecting cylinder by adjusting the first threaded assembly to adjust the tension of the wire.

[0009] In an optional embodiment, the support block and the adjusting cylinder are connected by a second threaded connection, and the relative position of the support block and the adjusting cylinder can be adjusted by the second threaded connection.

[0010] In an optional embodiment, the inner side of the wire guide spool is fitted with a soft sleeve to reduce wear on the wire when it slides on the soft sleeve.

[0011] In an optional embodiment, the connecting rod is fixedly connected to the wire guide spool by screws, so that part of the connecting rod is sleeved inside the adjusting cylinder and connected to the wire guide spool.

[0012] In an alternative embodiment, the wire feeding device further includes a connecting shaft, one end of which is fixedly connected to the support base, and the wire feeding spool is detachably mounted on the other end of the connecting shaft.

[0013] In an alternative embodiment, the wire feeding device further includes a bearing and a bearing housing, the bearing housing being mounted on the support base, the bearing being installed inside the bearing housing, and the rotating drum being rotatably connected to the bearing.

[0014] In an alternative embodiment, the axis of the rotating drum is parallel to the axis of the wire guide drum.

[0015] In an optional embodiment, the base is equipped with several identical wire-laying devices, which are used to release different types of wires.

[0016] Compared with the prior art, the present invention has the following technical effects: The present invention relates to a wire feeding device for stranding, which employs a feeding drum, a rotating drum, and a tension adjustment mechanism. The wire to be stranded is guided to the stranding device via the rotating drum and the tension adjustment mechanism. The stranding device pulls the wire off the feeding drum and releases it, thereby driving the tension adjustment mechanism and the rotating drum to rotate. This allows the rotating drum and the tension adjustment mechanism to continuously guide the wire to the stranding device. There is no need to use a drive component to drive the feeding device to rotate and feed the wire, which reduces production costs and avoids sudden changes in wire tension.

[0017] The tension adjustment mechanism can not only significantly adjust the wire tension before unwinding and stranding, but also further adjust the wire tension in real time during the unwinding and stranding process. This prevents the wire from breaking, deforming, becoming messy, or piling up due to excessive or insufficient tension, thus improving the stability of unwinding and ensuring the quality of the finished stranded wire.

[0024] Reference Figures 1-3 This utility model proposes a wire feeding device 100 for stranding wire.

[0025] In this embodiment of the utility model, the wire feeding device 100 for stranding includes a wire feeding device 1 and a base 2. The wire feeding device 1 is mounted on the base 2. The wire feeding device 1 includes a support 11, a wire feeding drum 12, a rotating drum 13, and a tension adjusting mechanism 14. The wire feeding drum 12 is connected to the support 11. The rotating drum 13 has a wire passing groove 131 that passes through the rotating drum 13 and is sleeved on the outside of the wire feeding drum 12 and is rotatably mounted on the support 11. The tension adjusting mechanism 14 is mounted on the rotating drum 13.

[0026] The tension adjustment mechanism 14 includes a connecting cylinder 141, an adjusting cylinder 142, a connecting rod 143, a wire guide cylinder 144, a support block 145, and an elastic element 146. The connecting cylinder 141 is mounted on the rotating drum 13. Part of the adjusting cylinder 142 is mounted inside the connecting cylinder 141, and the relative position of the adjusting cylinder 142 and the connecting cylinder 141 is adjustable. The connecting rod 143 is connected to the wire guide cylinder 144, and part of the connecting rod 143 is slidably sleeved inside the adjusting cylinder 142. The support block 145 is mounted inside the adjusting cylinder 142. The two ends of the elastic element 146 are respectively connected to the support block 145 and the connecting rod 143. The wire 200 is wound on the wire feeding drum 12 and can pass through the wire guide groove 131 and the wire guide cylinder 144 to extend to the stranding equipment. It can be pulled by the stranding equipment to drive the tension adjustment mechanism and the rotating drum 13 to rotate.

[0027] Specifically, the wire 200 to be stranded is wound on the pay-off drum 12. The wire 200 can be a copper cable, an aluminum cable, or a copper-clad aluminum cable. The pay-off drum 12 is fixedly connected to the support base 11. The wire 200 wound on the pay-off drum 12 can be led out from the pay-off drum 12, passing through the wire guide groove 131 and the wire guide drum 144 in sequence, and extending to the stranding equipment, where it is stranded. The stranding equipment pulls the wire 200, causing it to detach from the pay-off drum 12, and drives the tension adjustment mechanism 14 and the rotating drum 13 to rotate. This ensures that the wire guide groove 131 and the wire guide drum 144 can continuously guide the wire 200 to the stranding equipment, preventing the wire 200 from piling up messily in the pay-off device 1, improving the stability of the pay-off, eliminating the need for a drive component to drive the pay-off device 1 to rotate and reduce production costs.

[0028] During the process of wire 200 being released from the wire release device 1 and stranded by the stranding equipment, if the tension is too low, the wire 200 will pile up haphazardly within the wire release device 1; if the tension is too high, the wire 200 will break. The tension adjustment mechanism 14 can be used to adjust the tension of the wire 200 during release. Before the release begins, based on the layout of the wire release device 100 and the stranding equipment, or the material of the wire 200, the tension of the wire 200 can be significantly adjusted before release by adjusting the relative position of the adjusting cylinder 142 and the connecting cylinder 141. Specifically, the length of the adjusting cylinder 142 inserted into the connecting cylinder 141 is adjusted. When the adjusting cylinder 142 is inserted into the connecting cylinder 141, the tension of the wire 200 decreases during release; when the adjusting cylinder 142 extends out of the connecting cylinder 141, the tension of the wire 200 increases during release.

[0029] In addition to significantly adjusting the tension of the wire 200 before unwinding, the tension adjustment mechanism 14, including the adjusting cylinder 142, connecting rod 143, wire guide cylinder 144, support block 145, and elastic element 146, can also adjust the tension of the wire 200 in real time during the unwinding process. During unwinding, the wire 200 continuously compresses the wire guide cylinder 144. When the tension of the wire 200 becomes too high, the connecting rod 143 slides the wire guide cylinder 144 closer to the adjusting cylinder 142, increasing the size of the connecting rod 143 fitting into the connecting cylinder 141 and compressing the elastic element 146. The elastic element 146 is supported by the support block 145, thereby reducing the tension of the wire 200 and preventing it from breaking. When the tension of the wire 200 is too low, the elastic element 146 resets and pushes the connecting rod 143 to slide the wire guide 144 away from the adjusting cylinder 142, increasing the size of the connecting rod 143 extending out of the connecting cylinder 141, thereby increasing the tension of the wire 200 and preventing the wire 200 from piling up messily in the wire feeding device 1.

[0030] The elastic element 146 can be a spring. The rotating drum 13, connecting drum 141, adjusting drum 142, connecting rod 143, wire guide drum 144 and support block 145 are selected to have a certain strength to withstand the force during the wire feeding process, and are made of relatively light materials, including but not limited to polyethylene. Lighter materials can reduce the tension of the wire 200 during the wire feeding process.

[0031] In one embodiment of this utility model, a limiting block 147 is fixedly provided on the outer side of the connecting rod 143. In the direction in which the connecting rod 143 slides relative to the adjusting cylinder 142, the limiting block 147 abuts against the adjusting cylinder 142. The limiting block 147 can prevent the connecting rod 143 from disengaging from the adjusting cylinder 142 during the rotation of the rotating drum 13 carrying the tension adjustment mechanism, and can also limit the maximum tension of the tension adjustment mechanism 14 in real time to adjust the tension of the wire 200, so as to avoid the wire 200 breaking due to excessive tension.

[0032] In one embodiment of this utility model, the connecting cylinder 141 and the adjusting cylinder 142 are connected by a first threaded assembly 148. The adjusting cylinder 142 can adjust its relative position to the connecting cylinder 141 through the first threaded assembly 148 to adjust the tension of the wire 200. Rotating the adjusting cylinder 142 can adjust the length of the adjusting cylinder 142 extending out of the connecting cylinder 141. Increasing the length of the adjusting cylinder 142 extending out of the connecting cylinder 141 increases the tension of the wire 200; decreasing the length of the adjusting cylinder 142 extending out of the connecting cylinder 141 decreases the tension of the wire 200.

[0033] In one embodiment of this utility model, the support block 145 and the adjusting cylinder 142 are connected by a second threaded assembly 149. The relative position of the support block 145 and the adjusting cylinder 142 can be adjusted by the second threaded assembly 149. By adjusting the relative position of the support block 145 and the adjusting cylinder 142, the degree of compression of the elastic element 146 can be adjusted, thereby adjusting the sensitivity of the tension adjusting mechanism 14 in real time to adjust the tension of the wire 200.

[0034] In one embodiment of this utility model, a soft sleeve 1410 is fitted inside the wire guide spool 144 to reduce wear on the wire 200 when it slides on the soft sleeve 1410. The soft sleeve 1410 is made of one or more of rubber, sponge, or fabric. The connecting rod 143 is fixedly connected to the wire guide spool 144 by screws, so that part of the connecting rod 143 is fitted inside the adjusting cylinder 142 and connected to the wire guide spool 144. The process of installing the tension adjusting mechanism 14 is as follows: the connecting rod 143 is fitted into the inner side of the adjusting cylinder 142 from one end, and the connecting rod 143 is fixedly connected to the wire guide spool 144 from the inside by screws; then the elastic element 146 and the support block 145 are installed sequentially from one end of the adjusting cylinder 142; after the adjusting cylinder 142 is connected to the inner side of the connecting cylinder 141, the connecting cylinder 141 is installed on the rotating drum 13.

[0035] In one embodiment of the present invention, the wire feeding device 1 further includes a connecting shaft 15, one end of which is fixedly connected to a support base 11, and the wire feeding drum 12 is detachably installed at the other end of the connecting shaft 15. The wire feeding drum 12 is connected to the support base 11 via a support shaft.

[0036] In one embodiment of the present invention, the wire feeding device 1 further includes a bearing 16 and a bearing seat 17. The bearing seat 17 is mounted on the support seat 11, the bearing 16 is mounted inside the bearing seat 17, and the rotating drum 13 is rotatably connected to the bearing 16. The rotating drum 13 is rotatably connected to the support seat 11 through the bearing 16.

[0037] In one embodiment of the present invention, the axis of the rotating drum 13 is parallel to the axis of the wire guide drum 144, so as to facilitate the wire 200 passing through the wire guide drum 144.

[0038] In one embodiment of this utility model, a plurality of wire feeding devices 1 with the same structure are installed on the base 2. Different wire feeding devices 1 can be used for feeding the same or different types of wires 200, such as wires 200 with different sizes and materials.

[0039] In a specific application of this utility model, the wire 200 to be stranded is wound on the wire feeding drum 12. The wire 200 wound on the wire feeding drum 12 can be led out from the wire feeding drum 12, passing through the wire guide groove 131 and the wire guide drum 144 in sequence, and extending to the stranding device, where it is stranded into shape. The stranding device pulls the wire 200, causing it to detach from the wire feeding drum 12, and drives the tension adjusting mechanism 14 and the rotating drum 13 to rotate, so that the wire guide groove 131 and the wire guide drum 144 can continuously guide the wire 200 to be conveyed to the stranding device.

[0040] Before the wire feeding begins, the tension of the wire 200 can be significantly adjusted before feeding by adjusting the relative positions of the adjusting cylinder 142 and the connecting cylinder 141, depending on the wire feeding equipment 100 and the layout of the stranding equipment, or the material of the wire 200. Specifically, the length of the adjusting cylinder 142 inserted into the connecting cylinder 141 is adjusted. When the adjusting cylinder 142 is inserted into the connecting cylinder 141, the tension of the wire 200 decreases during feeding; when the adjusting cylinder 142 extends out of the connecting cylinder 141, the tension of the wire 200 increases during feeding.

[0041] In addition to significantly adjusting the tension of the wire 200 before unwinding, the tension adjustment mechanism 14, including the adjusting cylinder 142, connecting rod 143, wire guide cylinder 144, support block 145, and elastic element 146, can also adjust the tension of the wire 200 in real time during the unwinding process. During unwinding, the wire 200 continuously compresses the wire guide cylinder 144. When the tension of the wire 200 becomes too high, the connecting rod 143 slides the wire guide cylinder 144 closer to the adjusting cylinder 142, increasing the size of the connecting rod 143 fitting into the connecting cylinder 141 and compressing the elastic element 146. The elastic element 146 is supported by the support block 145, thereby reducing the tension of the wire 200 and preventing it from breaking. When the tension of the wire 200 is too low, the elastic element 146 resets and pushes the connecting rod 143 to slide the wire guide 144 away from the adjusting cylinder 142, increasing the size of the connecting rod 143 extending out of the connecting cylinder 141, thereby increasing the tension of the wire 200 and preventing the wire 200 from piling up messily in the wire feeding device 1.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
