Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stranded wire production technology, specifically relating to a stranded wire production line. Background Technology
[0002] Stranded wire is a power line or conductor core formed by winding multiple single wires together in a circular spiral according to certain rules and directions. This process enables wires and cables to have better anti-interference ability, flexibility and current carrying capacity. Stranded wire production lines mainly include processes such as cage stranding, non-woven fabric wrapping, and traction device traction. Among them, traction device traction can improve the overall tensile performance of the cable, adjust the roundness of the cable, reduce the bending rate of the cable and improve product quality.
[0003] Currently, most existing traction devices use two rows of traction wheels for traction. However, in the current technology, the traction wheels are basically fixed and the distance between the two rows of traction wheels cannot be adjusted. However, during the transportation of the stranded wire, due to long-distance traction, the overall slack of the stranded wire is prone to change and needs to be adjusted in a timely manner.
[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a stranding production line.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0008] A cross arm is fixed on the column, a first rotating shaft is inserted into the cross arm, a first traction wheel and a second traction wheel are rotatably mounted on the first rotating shaft, and a first connecting rod is fixed on the column, with a first rotating rod rotatably mounted on the first connecting rod.
[0009] The adjusting device is mounted on the cross arm and includes a slide rail. A slider is slidably mounted on the slide rail. A second rotating shaft is inserted into the slider. A third traction wheel is fixed on the second rotating shaft. A through hole is drilled in the slide rail.

A belt is installed between the second pulley and the third pulley. The belt is located inside the slide rail and meshes with the first pulley.
[0010] In one or more embodiments of this utility model, a first spring is installed between the first rotating rod and the first connecting rod. The first spring is used to pull the first rotating rod upward and tighten it so that the first pulley is pressed against the bottom end of the first traction wheel and the second traction wheel, thereby pressing the stranded wire onto the first traction wheel and the second traction wheel.
[0011] In one or more embodiments of this utility model, a first fixed shaft is fixed on the first rotating rod, and a first pulley is slidably disposed on the first fixed shaft. The first pulley is disposed at the bottom end of the first traction wheel and the second traction wheel. The first pulley is used to press against the bottom end of the first traction wheel and the second traction wheel, thereby pressing the stranded wire onto the first traction wheel and the second traction wheel.
[0012] In one or more embodiments of this utility model, a second connecting rod is fixed on the slider, a second rotating rod is rotatably mounted on the second connecting rod, and a second spring is installed between the second rotating rod and the second connecting rod. The second spring is used to pull the second rotating rod towards the second connecting rod, so that the second pulley is pressed against the top of the third traction wheel to press the stranded wire.
[0013] In one or more embodiments of this utility model, a second fixed shaft is fixed on the second rotating rod, and a second pulley is slidably disposed on the second fixed shaft. The second pulley is disposed on the upper end of the third traction wheel, and the second pulley is used to press the stranded wire onto the third traction wheel.
[0014] In one or more embodiments of this utility model, a limiting base is fixed at both ends of the slide rail on the cross arm. The limiting base is used to limit the slider and prevent the slider from sliding off the slide rail. A limiting rod is inserted into the limiting base to press against the protrusion and prevent the slider from sliding off the slide rail.
[0015] In one or more embodiments of this utility model, a third spring is installed between the limiting rod and the limiting base. The elastic force provided by the third spring plays a certain buffering role on the slider. A pair of protrusions are fixed on both sides of the slide rail, and the limiting rod holds the slider by pressing against the protrusions.
[0016] In one or more embodiments of this utility model, a plurality of slots are drilled on the bottom end of the slide rail, and a pair of insert rods are inserted into the bottom end of the slider. The insert rods are locked in the slots, thereby fixing the slider on the slide rail and preventing the slider from sliding.
[0017] In one or more embodiments of this utility model, a connector is fixed to one end of the insertion rod outside the slider. When the connector is pushed, the connector pushes a pair of insertion rods into the slot. A fourth spring is installed between the connector and the slider. The elastic force provided by the fourth spring pushes the connector away from the slider, thereby moving the insertion rods out of the slot.
[0018] In one or more embodiments of this utility model, a rotating shaft is fixed on the slider, and a control member is rotatably disposed at one end of the rotating shaft that passes through the connector. By rotating the control member, the connector is pushed to move toward the slider. The control member is provided with a first edge and a second edge.

Detailed Implementation
[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0033] like Figure 1-9 As shown, a stranding production line according to one embodiment of the present invention includes: a column 1 and an adjusting device 2.
[0034] like Figure 2 and 5 As shown, a cross arm 101 is fixed on the column 1, and a first rotating shaft 102 is inserted into the cross arm 101. The first rotating shaft 102 is used to install a first traction wheel 103 and a second traction wheel 104. The first traction wheel 103 and the second traction wheel 104 are rotatably mounted on the first rotating shaft 102 for the stranded wire to pass through. A first connecting rod 105 is fixed on the column 1, and a first rotating rod 106 is rotatably mounted on the first connecting rod 105. The first rotating rod 106 is used to install a first fixed shaft 109 and a first pulley 107.
[0035] like Figure 2 and 5 As shown, a first spring 108 is installed between the first rotating rod 106 and the first connecting rod 105. The first spring 108 is used to pull the first rotating rod 106 upward, so that the first pulley 107 is pressed against the bottom end of the first traction wheel 103 and the second traction wheel 104, thereby pressing the stranded wire onto the first traction wheel 103 and the second traction wheel 104. A first fixed shaft 109 is fixed on the first rotating rod 106, and the first pulley 107 is slidably arranged on the first fixed shaft 109. The first pulley 107 is located at the bottom end of the first traction wheel 103 and the second traction wheel 104, and is used to press the stranded wire against the bottom end of the first traction wheel 103 and the second traction wheel 104.
[0036] like Figure 1 and 7 As shown, the adjusting device 2 is mounted on the cross arm 101. The adjusting device 2 includes a slide rail 201, on which a slider 202 is slidably mounted. By sliding the slider 202 on the slide rail 201, the distance between the third traction wheel 204 and the first traction wheel 103 and the second traction wheel 104 is adjusted. A second rotating shaft 203 is inserted into the slider 202, and the third traction wheel 204 is fixed on the second rotating shaft 203. The second rotating shaft 203 drives the third traction wheel 204 to rotate, and the third traction wheel 204 is used for the stranded wire to pass through it. A through hole 227 is drilled in the slide rail 201, through which the second rotating shaft 203 slides when the slider 202 slides on the slide rail 201.
[0037] like Figure 1-7As shown, the second rotating shaft 203 passes through the through hole 227 and is fixed at one end within the slide rail 201 with a first pulley 210. The first pulley 210 drives the second rotating shaft 203 to rotate. A drive shaft 211 and a third fixed shaft 214 are inserted into the cross arm 101. When using this device, one end of the drive shaft 211 needs to be connected to an external drive device to rotate it. A second pulley 212 and a third pulley 213 are respectively mounted on the drive shaft 211 and the third fixed shaft 214. A belt 215 is installed between the second pulley 212 and the third pulley 213, allowing the second pulley 212 to drive the third pulley 213 to rotate via the belt 215. The belt 215 is located within the slide rail 201 and meshes with the first pulley 210, driving the first pulley 210 to rotate.
[0038] like Figure 7-9 As shown, a second connecting rod 205 is fixed on the slider 202, and a second rotating rod 206 is rotatably mounted on the second connecting rod 205. A second spring 209 is installed between the second rotating rod 206 and the second connecting rod 205. The second spring 209 is used to pull the second rotating rod 206 towards the second connecting rod 205, thereby causing the second pulley 208 to press against the top of the third traction wheel 204 and hold the stranded wire in place. A second fixed shaft 207 is fixed on the second rotating rod 206, and a second pulley 208 is slidably mounted on the second fixed shaft 207. The second pulley 208 is located at the upper end of the third traction wheel 204 and is used to press the stranded wire onto the third traction wheel 204.
[0039] like Figure 2 and 7 As shown, limit bases 216 are fixed at both ends of the slide rail 201 on the cross arm 101. The limit bases 216 are used to limit the slider 202 and prevent it from slipping off the slide rail 201. A limit rod 217 is inserted into the limit base 216 to press against the protrusion 219 and prevent the slider 202 from slipping off the slide rail 201. A third spring 218 is installed between the limit rod 217 and the limit base 216. The elastic force provided by the third spring 218 provides a certain buffering effect on the slider 202. A pair of protrusions 219 are fixed on both sides of the slide rail 201. The limit rod 217 presses against the protrusions 219 to hold the slider 202 in place.
[0040] like Figure 7-9As shown, multiple slots 228 are drilled on the bottom end of the slide rail 201. A pair of insert rods 220 are inserted into the bottom end of the slider 202. The insert rods 220 are locked in the slots 228, thereby fixing the slider 202 to the slide rail 201 and preventing the slider 202 from sliding. A connector 222 is fixed to one end of the insert rod 220 outside the slider 202. When the connector 222 is pushed, the connector 222 pushes the pair of insert rods 220 into the slots 228. A fourth spring 221 is installed between the connector 222 and the slider 202. The elastic force provided by the fourth spring 221 pushes the connector 222 away from the slider 202, thereby removing the insert rods 220 from the slots 228.
[0041] like Figure 7-9 As shown, a rotating shaft 223 is fixed on the slider 202. A control member 224 is rotatably mounted on one end of the rotating shaft 223 that passes through the connector 222. By rotating the control member 224, the connector 222 is pushed to move towards the slider 202. The control member 224 is provided with a first edge 225 and a second edge 226. The distance between the first edge 225 and the rotation axis of the control member 224 and the rotating shaft 223 is less than the distance between the second edge 226 and the rotation axis of the control member 224 and the rotating shaft 223. When the control member 224 is rotated so that the first edge 225 contacts the connector 222, the fourth spring 221 pushes the connector 222, causing the fourth spring 221 to move out of the slot 228. When the control member 224 is rotated so that the second edge 226 contacts the connector 222, the control member 224 pushes the connector 222, causing the insertion rod 220 to be inserted into the slot 228.
[0042] Working principle: First, before using this device, the drive shaft 211 needs to be connected to an external drive device to rotate it. Then, the stranded wire is transferred from... Figure 1 Pull the wire out from the left side and pull it to the first traction wheel 103 and the second traction wheel 104. Press the first fixed shaft 109 down and wind the stranded wire from the first traction wheel 103 from bottom to top. Then, release the first fixed shaft 109 so that the first pulley 107 presses on the stranded wire. Then, pull the stranded wire from the top of the first traction wheel 103 to the third traction wheel 204. First, lift the second fixed shaft 207 up and wind the stranded wire from the third traction wheel 204 from top to bottom. Then, release the second fixed shaft 207 so that the second pulley 208 presses on the stranded wire. Then, pull the stranded wire to the second traction wheel 104. Press the first fixed shaft 109 down again and pass the stranded wire through the bottom of the second traction wheel 104. Then, release the first fixed shaft 109 so that the first pulley 107 presses the stranded wire on the second traction wheel 104. Then, pull the stranded wire out of the device and proceed to the next process.
[0043] Then, the drive device connected to the drive shaft 211 is started to drive it to rotate. The drive shaft 211 drives the belt 215 to rotate through the second pulley 212. The belt 215 drives the first pulley 210 to rotate. The first pulley 210 drives the third traction wheel 204 to rotate through the second rotating shaft 203. The third traction wheel 204 drives the stranded wire to move.
[0044] When the position of the third traction wheel 204 needs to be adjusted, first rotate the control component 224 so that the first edge 225 contacts the connector 222. The elastic force of the fourth spring 221 pushes the connector 222, and the connector 222 drives the insertion rod 220 to move out of the slot 228. Then slide the slider 202 on the slide rail 201 to adjust the position of the third traction wheel 204. After the adjustment is completed, reverse the control component 224 so that the second edge 226 contacts the connector 222. The control component 224 pushes the connector 222 to insert the insertion rod 220 into the slot 228, and the slider 202 can be fixed on the slide rail 201 again.
