Description

Technical Field

[0001] This utility model belongs to the technical field of cable stranding machines, specifically a cable stranding device. Background Technology

[0002] A cable stranding machine is a device used to strand multiple single wires into cable cores according to certain rules. It uses a motor to drive the rotating parts to rotate at high speed, so that multiple single wires are spirally stranded at a set pitch. Then, the cores are neatly wound up by the traction and winding mechanism. It can efficiently complete the stranding process of cables and significantly improve the mechanical strength and electrical performance of cables.

[0003] During cable stranding, multiple reels release single wires, which are then pulled by the traction winding assembly through the stranding holes for stranding. As the number of single wires in the reels decreases, the tension of the single wires in the stranding machine decreases, and the single wires become loose as they pass through the stranding holes in the stranding machine. Failure to tighten the cable in time will result in loose cable stranding.

[0004] Therefore, a cable stranding device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a cable stranding device.

A wire feeding component is installed on the top of the base one, a support plate is installed on the top of the base two, a stranding hole is provided inside the support plate, a tensioning component is installed on the top of the base two, and a winding component is provided on the right side of the tensioning component.

[0007] The tensioning assembly includes a mounting frame one and a mounting frame two. A first pulley is rotatably mounted on the front of the mounting frame one. A sliding groove is formed on the front of the mounting frame two. A sliding frame is fixedly mounted on the back of the mounting frame two.

A rotating shaft is rotatably mounted on the front of the movable block. A second pulley is sleeved on the outer surface of the rotating shaft.

[0008] Furthermore, the rotating shaft is located inside the slide groove, and the moving block is located inside the sliding frame. The moving block slides inside the sliding frame, which can drive the rotating shaft to move together inside the slide groove, thereby adjusting the position of the second pulley.

[0009] Preferably, both mounting bracket one and mounting bracket two are fixedly mounted on the top of base two, mounting bracket two is located on the right side of mounting bracket one, and the rotating shaft is located inside the slide groove.

[0010] Preferably, the wire feeding assembly includes a drive motor mounted on the top of a base, a placement frame rotatably mounted on the output shaft of the drive motor, a plug rod fixedly mounted on the top of the placement frame, a closing cover threaded onto the outer surface of the plug rod, a rotating rod fixedly mounted on the right side of the placement frame, a stranded wire reel fixedly sleeved on the outer surface of the rotating rod, and a wire outlet opening inside the stranded wire reel.

[0011] Furthermore, the winding assembly pulls the cable to wind it up, which can cause the wire feeding reel on the outer surface of the plug to rotate, thus feeding and twisting the single wire.

[0012] Preferably, multiple plug-in rods and closing covers are provided, and the multiple plug-in rods and closing covers are arranged in a circumferential array on the outer surface of the placement frame for rotating and installing multiple pay-off reels.

[0014] Preferably, a control box is installed on the top of the second base, and the control box is used to control the start and stop of the first drive motor and the second drive motor.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, the cable passes through the top of the outer surface of the first pulley and then through the bottom of the outer surface of the second pulley, and is wound into the inside of the winding assembly. When the cable becomes loose, the weight of the counterweight will press down on the sliding rod and the moving block, causing the moving block to move downward inside the sliding frame, which in turn drives the second pulley to move downward as well. This can adjust the height difference between the first and second pulleys, tighten the cable, and achieve the effect of adjusting the cable tension, thus avoiding the problem of loose cable cores.

[0017] 2. In this utility model, a single wire in the pay-off reel is passed through the outlet of the twisting reel, and then multiple single wires are passed through the twisting hole. After passing through the first pulley and the second pulley, they are wound into the take-up reel. The first drive motor and the second drive motor are started, which drive the multiple pay-off reels and twisting reels on the placement frame to rotate together. At the same time, the second drive motor drives the take-up reel to rotate, pulling the pay-off reel to rotate, so that the single wires are twisted into a cable core through the twisting hole.

[0029] Through the above technical solution, the wire feeding assembly 12 is installed on the top of the base 1. Multiple single wires can be twisted together by the wire feeding assembly 12 and the twisting hole 21. After the twisting is completed, the tension of the cable is adjusted by the tensioning assembly 3 on the top of the base 11. Finally, it is wound into the winding assembly 4. The winding assembly 4 can pull the cable to wind it up.

[0030] The tensioning assembly 3 includes a mounting bracket 1 301 and a mounting bracket 2 302. A first pulley 311 is rotatably mounted on the front of the mounting bracket 1 301. A sliding groove 303 is opened on the front of the mounting bracket 2 302. A sliding frame 304 is fixedly mounted on the back of the mounting bracket 2 302. A moving block 305 is slidably mounted inside the sliding frame 304. A sliding rod 306 is fixedly mounted on the top of the moving block 305. A plug-in post 307 is installed on the top of the sliding rod 306 and extends to the outside of the sliding frame 304. A counterweight 308 is sleeved on the outer surface of the plug-in post 307. A rotating shaft 309 is rotatably mounted on the front of the moving block 305. A second pulley 310 is sleeved on the outer surface of the rotating shaft 309.

[0031] Mounting bracket 1 301 and mounting bracket 2 302 are both fixedly mounted on the top of base 2 11. Mounting bracket 2 302 is located on the right side of mounting bracket 1 301. The rotating shaft 309 is located inside the slide groove 303.

[0032] Through the above technical solution, mounting bracket 1 301 is fixedly installed on the top of base 2 11, and the first pulley 311 can be rotatably installed on the front of mounting bracket 1 301. The twisted cable can pass through the first pulley 311. Mounting bracket 2 302 is located on the right side of mounting bracket 1 301. A through groove 303 is opened on the front of mounting bracket 2 302. Sliding bracket 304 is installed on the back of groove 303. A movable block 305 that can move up and down is installed inside sliding bracket 304. A sliding rod 306 that extends through to the outside of sliding bracket 304 is installed on the top of movable block 305, so that counterweight 308 can be installed on the outer surface of plug post 307. Plug post 307 is fixed to the top of sliding rod 306. Counterweight 308 can provide downward pressing force on movable block 305, and rotate shaft 309 is rotatably installed. On the front of the movable block 305, the rotating shaft 309 passes through the slide groove 303 and is mounted on the second pulley 310.

The weight of the counterweight block 308 remains unchanged. When the cable core becomes loose, the counterweight block 308 will press the movable block 305 and the second pulley 310 downward, which can adjust the height difference between the first pulley 311 and the second pulley 310, tighten the cable, and achieve the effect of adjusting the tension of the cable.

[0033] Considering the issue of how to lay out and twist single wires, the following is provided: Figure 1 and Figure 5 The specific structure of the wire feeding assembly 12 is disclosed. The wire feeding assembly 12 includes a drive motor 101 installed on the top of the base 1. The output shaft of the drive motor 101 is rotatably mounted on a placement frame 102. A plug rod 103 is fixedly installed on the top of the placement frame 102. A closing cover 104 is threadedly connected to the outer surface of the plug rod 103. A rotating rod 105 is fixedly installed on the right side of the placement frame 102. A stranding reel 106 is fixedly sleeved on the outer surface of the rotating rod 105. A wire outlet 107 is opened inside the stranding reel 106.

[0034] Multiple plug-in rods 103 and closing covers 104 are provided. Multiple plug-in rods 103 and closing covers 104 are arranged in a circumferential array on the outer surface of the placement frame 102 for rotating and installing multiple pay-off reels.

[0035] Through the above technical solution, the drive motor 101 is installed and fixed on the top of the base 1. The output shaft of the drive motor 101 is connected to the left side of the placement frame 102. When the drive motor 101 is started, it can drive the placement frame 102 to rotate. Multiple plug rods 103 and closing covers 104 are installed on the outer surface of the placement frame 102. The pay-off reel can be plugged into the outer surface of the plug rods 103. By threading the closing cover 104 to the outer surface of the plug post 307, the closing cover 104 can limit and fix the pay-off reel to the plug rods 103. The internal structure allows multiple pay-off reels to be mounted on the outside of the placement frame 102 and rotate together. The stranding reel 106 is sleeved on the outer surface of the rotating rod 105, which is also fixedly mounted on the right side of the placement frame 102, so that the placement frame 102 can drive the stranding reel 106 to rotate together. The stranding reel 106 has multiple outlet ports 107 inside. The single wires from the multiple pay-off reels can pass through the outlet ports 107 and enter the inside of the stranding hole 21. By pulling the cable with the take-up assembly, the single wires can be twisted inside the stranding hole 21.

[0036] Secondly, considering the issue of how the cable is wound up, please provide... Figure 1 and Figure 6 The specific structure of the winding assembly 4 is disclosed. The winding assembly 4 includes a fixed frame 401 fixedly installed on the top of the base 11. The fixed frame 401 has a hole on its front side. A fixed rod 402 is rotatably installed inside the hole. A drive motor 403 is installed through the fixed frame 401 on the back side of the fixed rod 402. A take-up reel 404 is sleeved on the outer surface of the fixed rod 402.

[0037] Through the above technical solution, two fixing frames 401 are fixedly installed on the top of the base 2 11, so that the fixing rod 402 can be rotatably installed inside the hole opened inside the fixing frame 401. The take-up reel 404 can be sleeved on the outer surface of the fixing rod 402. The output shaft of the drive motor 2 403 is connected to the back of the fixing frame 401. When the drive motor 2 403 is powered on, it drives the fixing rod 402 and the take-up reel 404 to rotate, which can make the cable connected to the take-up reel 404 rotate and can pull the single line from the pay-off reel through the twisting hole 21 to twist together, thereby achieving the effect of winding and pulling the cable.

[0038] Finally, show Figure 1 A control box 5 is installed on the top of the base 2 11. The control box 5 is used to control the start and stop of the drive motor 1 101 and the drive motor 2 403.

[0039] Through the above technical solution, the control box 5 can energize drive motor 101 and drive motor 203 respectively, and control the start-stop and output power of drive motor 101 and drive motor 203.

[0040] In summary, the working principle of this utility model is as follows:

[0041] When twisting the cable, the pay-off reel of the single wire to be twisted is inserted into the outer surface of the connector rod 103. By threading the closing cover 104 to the outer surface of the connector post 307, the pay-off reel is fixed to the inside of the connector rod 103. The single wire in the pay-off reel passes through the outlet 107 inside the twisting reel 106, and then multiple single wires pass through the twisting hole 21, passing through the top of the first pulley 311 and the bottom of the second pulley 310 and being wound into the take-up reel 404. The counterweight 308 will press down on the slide rod 306 and the moving block 305. The moving block 305 drives the second pulley 310 to be pressed down by the counterweight 308, so that when the cable core passes through the second pulley 310, it can be pressed down and tightened by the second pulley 310. The drive motor 101 and the drive motor are started. Motor 2 403 drives multiple feed reels and stranding reels 106 on the placement frame 102 to rotate together. At the same time, drive motor 2 403 drives take-up reel 404 to rotate, pulling the feed reels to rotate, so that the single wire passes through the stranding hole 21 and is stranded into a cable core. Drive motor 1 101 and drive motor 2 403 work continuously, so that the cable core is stranded and wound into the take-up reel 404. When the feed reel continues to feed less wire, the cable tension decreases and becomes loose. The weight of counterweight 308 will press the second pulley 310 downward, increasing the height difference between the first pulley 311 and the second pulley 310. This can open and tighten the cable passing through the first pulley 311 and the second pulley 310, avoiding the problem of loose cable core stranding.
