Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, specifically to a shaping guide wheel mechanism and its winding machine and cable conductor stranding equipment. Background Technology

[0002] As a cable manufacturing equipment, the operating principle of the cable conductor stranding equipment is as follows: the traction drives the single wire to be drawn out from the drop frame, and after passing through the guide wheel, it directly enters the wire separating plate, and then enters the stranding pan after passing through the paralleling die. The high-speed rotation of the stranding pan forms the pitch and then leads it into the take-up reel.

[0003] However, cable conductor stranding equipment suffers from wire skipping during operation. To address this issue, CN113178289A discloses a cable conductor stranding device that prevents conductor skipping, comprising:

[0004] The centerline tension adjustment device is used to adjust the centerline of the cable. The centerline of the cable enters the centerline tension adjustment device and is wound around at least two tension wheels. One of the tension wheels is movable. The centerline can be kept taut at all times by the autonomous movement of the tension wheel.

[0005] The paralleling device is equipped with a horizontally movable paralleling mold frame. The center line of the cable and multiple monofilaments led out from the drop frame pass through the paralleling mold frame together. The paralleling mold frame can be moved as a whole towards the bow, which facilitates the operator's operation of the pull head and reduces the distance between the paralleling mold and the bow.

[0006] The bow winch has several shaped guide rollers evenly installed on the bow. The shaped guide rollers are installed at both ends of the bow near the shaft. The wire coming out of the wire-parallel forming frame enters the bow winch and passes around the shaped guide rollers in sequence before being guided into the take-up reel in the middle of the bow winch. The shaped guide rollers at both ends can prevent the cable from being transmitted at large angles and avoid deformation.

[0007] Although the above-mentioned cable conductor stranding equipment reduces the probability of conductor skipping, the shaping guide wheel is fixedly installed on the stranding bow and cannot dynamically adjust the guide angle according to the stranding state. This results in the problem of conductor skipping due to sudden angle changes when entering the stranding bow. Utility Model Content

[0008] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a shaping guide wheel mechanism, its bow winding machine, and cable conductor stranding equipment, so as to solve the problem that in existing technologies, because the shaping guide wheel is fixedly installed on the bow, it is impossible to dynamically adjust the guiding angle according to the stranding state, resulting in wire skipping when the conductor enters the bow due to sudden angle changes.

[0009] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a shaped guide wheel mechanism for mounting on the drawbar of a bow winch, comprising a shaped guide wheel and a mounting assembly connecting the shaped guide wheel and the drawbar, the mounting assembly comprising:

[0010] A detachable connector, which is detachably connected to the pantograph;

[0011] The mounting part is rotatably connected to the detachable connecting seat, and elastic telescopic members are elastically abutting each other on both sides of the mounting part along its rotation direction. The shaping guide wheel is detachably connected to the mounting part.

[0012] The second aspect of this utility model adopts the following technical solution: a bow winch, including a shaped guide wheel mechanism as described in the first aspect of this utility model.

[0013] The third aspect of this utility model adopts the following technical solution: a cable conductor stranding device, including a bow stranding machine as described in the second aspect of this utility model.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This shaping guide wheel mechanism mainly consists of a shaping guide wheel and an installation assembly. The detachable connecting seat is detachably connected to the bow to facilitate the replacement of this shaping guide wheel mechanism on the bow. The installation part is rotatably connected to the detachable connecting seat. At the same time, two elastic telescopic members cooperate with the installation part to allow the shaping guide wheel to finely adjust its guiding angle according to the winding state, reducing the probability of wire skipping due to sudden angle changes when the conductor enters the bow.

Detailed Implementation

[0020] The present invention will be further described in detail below through specific embodiments:

[0021] like Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model embodiment proposes a shaped guide wheel mechanism for installation on the drawbar 1 of a drawbar winch. The mechanism includes a shaped guide wheel 21 and an installation assembly connecting the shaped guide wheel 21 and the drawbar 1. The installation assembly includes a detachable connecting seat 22 and an installation part 23. The detachable connecting seat 22 is detachably connected to the drawbar 1. The installation part 23 is rotatably connected to the detachable connecting seat 22, and elastic telescopic members 24 elastically abut against each other on both sides of the installation part 23 along its rotation direction. The shaped guide wheel 21 is detachably connected to the installation part 23.

[0022] This shaping guide wheel mechanism mainly consists of a shaping guide wheel 21 and an installation assembly. The detachable connecting seat 22 is detachably connected to the coiler 1 to facilitate the replacement of this shaping guide wheel mechanism on the coiler 1. The installation part 23 is rotatably connected to the detachable connecting seat 22. At the same time, two elastic telescopic members 24 cooperate with the installation part 23 to allow the shaping guide wheel 21 to be finely adjusted according to the coiling state, thereby reducing the probability of wire skipping due to sudden angle changes when the conductor enters the coiler 1.

[0023] To make the guide angle of the shaping guide wheel 21 more stable during fine-tuning, such as Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the shaping guide wheel mechanism further includes a guide seat 25. The guide seat 25 is fixedly mounted on the detachable connecting seat 22 and has a receiving cavity formed therein. The guide seat 25 has a guide hole 251 that communicates with the receiving cavity and is arranged along the rotation direction of the mounting part 23. One end of the mounting part 23 connected to the detachable connecting seat 22 is placed in the receiving cavity and passes through the guide hole 251. The elastic telescopic member 24 is disposed in the receiving cavity.

[0024] In this embodiment, the guide seat 25 is U-shaped and its two ends are fixedly connected to the bottom of the detachable connecting seat 22, and the guide hole 251 is opened on the bottom side of the guide seat 25.

[0025] It can be seen that the guide seat 25 is designed so that after it is connected to the bottom of the detachable connecting seat 22, the guide seat 25 and the bottom of the detachable connecting seat 22 together form the receiving cavity. The receiving cavity accommodates the connection point between the mounting part 23 and the detachable connecting seat 22, and also accommodates the elastic telescopic member 24. When this shaping guide wheel mechanism is assembled on the cable bow 1, during the operation of the cable conductor stranding equipment, the shaping guide wheel 21 causes the mounting part 23 to rotate relative to the detachable connecting seat 22 according to the stranding state. The guide hole 251 limits and guides the rotation of the mounting part 23, so that the adjustment of the shaping guide wheel 21 is more stable.

[0026] Based on the above scheme, the structure of the mounting part 23 will be described in detail; as follows: Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the shaping guide wheel mechanism includes a mounting part 23 comprising a connecting strip 231 and a mounting base 232. One end of the connecting strip 231 is placed in the receiving cavity to be rotatably connected to the detachable connecting base 22, and the other end of the connecting strip 231 freely passes through the guide hole 251. Two elastic telescopic members 24 are distributed on opposite sides of the connecting strip 231 and cooperate with it. The mounting base 232 is fixedly connected to the end of the connecting strip 231 that is placed outside the receiving cavity, and the shaping guide wheel 21 is detachably connected to the mounting base 232.

[0027] In this embodiment, two mounting blocks are fixedly connected to the bottom of the detachable connecting seat 22, and one end of the connecting strip 231 is movably arranged between the two mounting blocks and is rotatably connected through the connecting shaft 23a, so that the mounting part 23 is rotatably connected to the detachable connecting seat 22; wherein, a torsion spring that abuts against the two mounting blocks may also be sleeved on the connecting shaft 23a, so that the connecting strip 231 remains vertical when the shaping guide wheel 21 is not subjected to external force.

[0028] Here: Both elastic telescopic components 24 can be elastic telescopic rods. The two elastic telescopic rods are elastically abutted against one end of the connecting strip 231, which is rotatably connected to it. At the same time, the guide hole 251 guides the connecting strip 231 to ensure that the shaping guide wheel 21 can be finely adjusted according to the twisting state to stabilize its guiding angle.

[0029] The ends of both elastic telescopic rods that abut against the connecting strip 231 are smooth arc surfaces, thus preventing the rotational adjustment of the connecting strip 231 from being restricted.

[0030] To facilitate the replacement of different shaping guide wheels 21, the mounting base 232 is detachably connected to the shaping guide wheel 21 via a connector 233. The bottom of the mounting base 232 has a mounting notch, and the shaping guide wheel 21 is partially movably arranged within the mounting notch.

[0031] The connector 233 includes a connecting shaft 23a, which freely passes through the mounting hole on the mounting base 232 and the mounting hole on the shaping guide wheel 21, and both ends of the connecting shaft 23a are threadedly connected to locking nuts 23b that abut against the outside of the mounting base 232.

[0032] Here, the shaping guide wheel 21 is stably installed in the mounting notch by the cooperation of the connecting shaft 23a and the two locking nuts 23b. When it is necessary to replace the shaping guide wheel 21 with a different model to meet the needs of conductors with different wire diameters and materials, one of the locking nuts 23b is unscrewed from the connecting shaft 23a, and then the connecting shaft 23a is pulled out from the mounting hole on the mounting base 232 and the mounting hole on the shaping guide wheel 21. At this time, the new shaping guide wheel 21 is placed in the mounting notch, and the connecting shaft 23a is freely passed through the mounting hole on the mounting base 232 and the mounting hole on the new shaping guide wheel 21. Finally, the locking nut 23b is tightened to quickly complete the replacement of the shaping guide wheel 21.

[0033] Based on the above scheme, the structure of the detachable connector 22 will be described in detail; as follows: Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the fixed guide wheel mechanism includes a detachable connecting seat 22 comprising a connecting seat body 221 and a positioning block 222. The top of the connecting seat body 221 has an assembly opening for the bow 1 to pass through, and two assembly holes located on different sides of the assembly opening are opened on its top. The mounting part 23 is rotatably connected to the connecting seat body 221. The positioning block 222 freely passes through the two assembly holes and is threadedly connected to a top rod 223 for abutting against the bow 1 to limit its position.

[0034] In this embodiment, the connecting seat 221 is U-shaped, and the two mounting holes are correspondingly opened on both ends of the connecting seat 221. When the detachable connecting seat 22 is assembled with the bow 1, the bow 1 is inserted into the mounting opening and fitted, then one end of the positioning block 222 is freely passed through the two mounting holes, and then the top rod 223 is connected to the positioning block 222 and rotated until one end of the top rod 223 abuts against the bow 1, so that the detachable connecting seat 22 is fixedly connected to the bow 1, so that the shaping guide wheel mechanism is stably installed on the bow 1.

[0035] When it is necessary to separate the shaping guide wheel mechanism from the bow 1: hold the top rod 223 and rotate it until it is disengaged from the positioning block 222; then move the positioning block 222 out of the two mounting holes, at which point the bow 1 can be moved out of the opening of the mounting port to complete the separation of the shaping guide wheel mechanism from the bow 1.

[0036] The shaped guide wheel mechanism is applied to a bow winch. According to another embodiment of the present invention, the bow winch includes the shaped guide wheel mechanism described in any of the above embodiments as well as other existing structures, so that the bow winch has the advantages of the shaped guide wheel mechanism.

[0037] The bow stranding machine is applied to a cable conductor stranding device. According to another embodiment of the present invention, the cable conductor stranding device includes a bow stranding machine as described in any of the above embodiments and other existing structures, so that the cable conductor stranding device has the advantages of the bow stranding machine.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
