Description

Technical Field

[0001] The present invention relates to the technical field of cable stranding machines, and particularly relates to a cable production stranding machine with uniform wire release tension. Background Art

[0002] Cables mainly play the role of transmitting electric energy. According to different voltages, the cross-sectional area of their conductors is also different. Single conductors are not easy to bend and have poor flexibility, which brings difficulties to production, transportation, installation, laying, and use. Due to the large cross-sectional area of single conductors and large eddy current losses, which affect the power transmission effect, cable stranding has emerged. It can not only ensure electrical performance but also have a certain degree of flexibility in mechanical properties. Stranding machines are widely used in various types of soft or hard conductor wires to twist multiple single conductors into one strand to meet the process requirements of the wire; When conducting wire stranding, usually due to factors such as the self-gravity of the bare wire, frictional resistance, and misalignment of the wire during installation, the tension of each wire is different, which not only affects the stranding effect but also affects the uniformity of the electrical conductivity after cabling. Therefore, we propose a cable production stranding machine with uniform wire release tension. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a cable production stranding machine with uniform wire release tension, including: A bottom plate, the bottom of the bottom plate is fixedly connected with support legs; A stranding mechanism, the stranding mechanism is fixedly installed on the side of the bottom plate away from the support legs; Among them, the stranding mechanism includes: A stranding module, the stranding module is fixedly connected to the side of the bottom plate away from the support legs; A guiding component, the guiding component is arranged on the incoming wire side of the stranding module, and a fixing block is fixedly connected to the outer side surface of the guiding component. The side of the fixing block away from the guiding component is fixedly connected to the top of the bottom plate; A wire release component, the wire release component is arranged on the side of the guiding component away from the stranding module, and the wire release component is fixedly installed on the top of the bottom plate; A tensioning component, the tensioning component is fixedly connected to the side of the guiding component away from the wire release component; A driving component, the driving component is fixedly connected to the side of the wire release component away from the guiding component, and a mounting plate is fixedly connected to the surface of the driving component. The side of the mounting plate away from the driving component is fixedly connected to the top of the bottom plate; The driving component drives the wire release component, the guiding component, and the tensioning component to rotate. The wire release component has a cleaning structure, and the stranding module has a stranding structure; A number of bare wires are wound around the wire pay-off assembly, and then the bare wires are pulled. The wires pass through the wire pay-off assembly, the guiding assembly, and the tensioning assembly in sequence. Finally, several wires converge inside the stranding module, and the stranding module twists several wires. When the bare wires pass through the wire pay-off assembly, the cleaning structure of the wire pay-off assembly cleans the surface of the wires, removing impurities and grease on the wire surface, reducing the resistance of the wires after stranding, ensuring the wire efficiency of the wires, and after the impurities are removed, the wire performance unevenness of local wires is avoided, and problems such as local overheating caused by resistance differences are avoided, ensuring the stable conductivity of the cable during long-term use. At the same time, after removing impurities such as grease and dust, the friction between wires is prevented from decreasing, and it is avoided that the wires are difficult to be tightly stranded. After cleaning, the wire surface is clean, and it can better fit each other during stranding, increasing the stranding tightness, making the cable structure more stable, and preventing the stranded wires from loosening.

[0004] Further, the wire pay-off assembly includes a mounting seat, the mounting seat is fixedly connected to the top of the bottom plate, a pay-off cylinder is rotatably connected to the inner side surface of the mounting seat, a pay-off shaft is fixedly connected to the inner side surface of the pay-off cylinder, a pay-off seat is fixedly connected to the side of the pay-off cylinder away from the mounting seat, several pay-off seats are evenly distributed along the circumferential direction of the pay-off cylinder, and a reel is rotatably connected to the side of each of the several pay-off seats close to the pay-off shaft through a rotating rod. The bare wires are wound around the reels, and the bare wires are wound on several reels. After the wires are stranded, the wires are pulled, and the reels pay off the wires, gradually completing the stranding of the wires.

[0005] Further, a rod body is fixedly connected to the side of the pay-off cylinder away from the mounting seat, several rod bodies are provided, and the rod bodies are arranged at intervals between several pay-off seats. A fixed outer ring is provided on the side of the rod body away from the pay-off cylinder, and the inner side surface of the fixed outer ring is fixedly connected to the inner side surface of the rod body. A limiting frame is fixedly connected to the inner side surface of the fixed outer ring, and a fixed inner ring is fixedly connected to the side of the limiting frame close to the pay-off shaft. Several limiting frames are evenly distributed along the circumferential direction of the fixed outer ring. The limiting frame is set in an H-like shape, and the center of the limiting frame is set in a ring shape. The wires are passed through the limiting frame. When the wires are paid off from the reels, the pay-off positions of the wound wires change continuously, and the wires vibrate. The vibration of the wires drives the deformation of the limiting frame. The H-like limiting frame can deform in all directions, which can buffer the swing of the wires, thereby reducing the swing of the wires and ensuring the tight stranding of the subsequent wires.

[0006] Furthermore, a fixing plate is arranged inside the ring of the limiting frame. A plurality of the fixing plates are evenly distributed along the circumferential direction of the inner side surface of the ring of the limiting frame. A plurality of elastic plates are arranged on one side of each of the plurality of fixing plates away from each other, and the elastic plates are respectively fixedly connected to the four corners of the fixing plate. One end of the elastic plate away from the fixing plate is fixedly connected to the inner side surface of the ring of the limiting frame. The wire passes through the middle of the ring of the limiting frame, and then the fixing plate is squeezed, and the elastic plate deforms, so as to limit the wire. When the wire swings, the elastic plate can buffer the small swing of the wire, further limit the swing of the wire, and further ensure the tightness during the stranding of the wire.

[0007] Furthermore, a cleaning frame is arranged at the interval between the wire pay-off reel and the fixed outer ring. The inner side surface of the cleaning frame is slidably connected to the surface of the rod body. Rubber plates are symmetrically arranged at the intervals between adjacent rod bodies, and the rubber plates are fixedly connected to the inner side surface of the cleaning frame. One end of the two rubber plates away from the inner side surface of the cleaning frame is bent towards the side close to each other. A cleaning ring is fixedly connected to the side of the two rubber plates close to each other. The cross-section of the cleaning ring is arranged in a V-like shape. The two sides of the cleaning ring are bent towards the side away from each other, and the two sides of the cleaning ring are respectively embedded into the two rubber plates, and the surface of the cleaning ring is fixedly connected to the inner side surface of the rubber plate. A first spring is fixedly connected to the side of the cleaning frame close to the wire pay-off reel. One end of the first spring away from the cleaning frame is fixedly connected to the side of the wire pay-off reel close to the cleaning frame, and the first spring is sleeved on the surface of the rod body. The wire passes through the cleaning ring, and the cleaning ring deforms to wrap the surface of the wire. When the wire passes through, the cleaning ring scrapes the surface of the wire, so as to complete the cleaning of the wire. At the same time, when the wire passes through the cleaning ring, the rubber plate deforms to prevent the cleaning ring from scratching the wire and avoid wire damage affecting the conductivity after stranding. And the two ends of the cleaning ring are embedded into the rubber plate to strengthen the fixation of the cleaning ring, thereby avoiding the cleaning ring falling off during wire cleaning. When the wire passes through the cleaning ring, it drives the cleaning frame to move, so as to drive the first spring to deform, so as to buffer the movement of the cleaning frame and further ensure the smooth stranding of the wire.

[0008] Further, the guiding assembly includes a shield. The shield is arranged in a conical shape, and the end with a smaller diameter of the shield faces the stranding module. The outer side surface of the shield is fixedly connected to the side of the fixed block away from the bottom plate. A guiding shaft is arranged inside the shield, and one end of the guiding shaft away from the stranding module is fixedly connected to one end of the pay-off shaft away from the pay-off reel. The inner side surface of the shield is slidably connected with a guiding plate. The inner side surface of the guiding plate is fixedly connected to the surface of the guiding shaft, and a plurality of guiding plates are evenly distributed inside the shield. After the wire passes through the limiting frame, it sequentially passes through a plurality of guiding plates. The plurality of guiding plates inside the conical shield are evenly distributed, which can guide multiple wires to move closer to each other and gradually converge into a strand that can pass through the stranding module, ensuring the smooth stranding of the wires. Moreover, the plurality of guiding plates isolate the plurality of wires in a conical shape, preventing them from naturally converging into a cone and causing entanglement with each other.

[0009] Further, the tensioning assembly includes a tension shaft. The tension shaft is fixedly connected to one end of the guiding shaft away from the pay-off shaft. A smooth cylinder is fixedly connected to the surface of the tension shaft. A connecting plate is fixedly connected to the outer side surface of the smooth cylinder. The wire passes through the guiding plate and then through the smooth cylinder. A plurality of wires pass through the smooth cylinder in parallel, limiting the gradually forming strand of wires to prevent the wires from spreading, and at the same time ending the tendency of the wires to form a cone, ensuring the smooth stranding of the wires.

[0010] Further, rollers are symmetrically arranged at the interval between the connecting plate and the smooth cylinder. Rotating seats are arranged on the sides of the two rollers away from each other. The inner side surface of the rotating seat is rotationally connected to the roller through a rotating rod. The wire penetrates into one end of the smooth cylinder, then passes through the interval between the two rollers, and then penetrates out from the other end of the smooth cylinder. By driving the two rollers to move up and down, the tension of the wire is adjusted to ensure that the tension of a plurality of wires is uniform during stranding and ensure the stranding quality of the wires.

[0011] Further, a telescopic rod is fixedly connected to the side of the connecting plate close to the roller. One end of the telescopic rod away from the connecting plate is fixedly connected to the side of the rotating seat close to the connecting plate and away from the roller. A sliding seat is fixedly connected to the outer side surface of the smooth cylinder. A sliding rod is slidably connected to the inner side surface of the sliding seat. A second spring is fixedly connected to the surface of the sliding rod. One end of the second spring away from the sliding seat is fixedly connected to the side of the rotating seat close to the sliding seat and away from the roller. When the telescopic rod is started, the telescopic rod drives the rotating seat to move, drives the roller to move, drives the wire to move, thereby driving the other roller and the other rotating seat to move, and finally drives the sliding rod to slide inside the sliding seat. At the same time, the second spring deforms, thereby squeezing the wire to adjust the tension of the wire during stranding. When the wire passes through, the two rollers rotate to ensure the smooth passing of the wire, and the two rollers cooperate with each other to limit the wire to prevent entanglement between the wires.

[0012] Further, the driving assembly includes a motor, which is fixedly connected to the inner side of the mounting plate. One side of the motor close to the wire pay-off reel is fixedly connected with a rotating shaft, which is fixedly connected to the output end of the motor. The end of the rotating shaft away from the motor is fixedly connected to one end of the wire pay-off shaft located inside the wire pay-off reel. When the motor is started, the output end of the motor drives the rotating shaft to rotate, thereby driving the wire pay-off shaft, the guiding shaft, and the tension shaft to rotate. The wire pay-off shaft drives the wire pay-off reel and the components fixed on the wire pay-off reel and the wire pay-off shaft to rotate, and then drives the wire to rotate slowly. The stranding module drives the wire to rotate and winds the stranded wire from the end away from the motor, gradually completing the stranding of the wire.

[0013] The beneficial effects of the present invention are as follows: By setting the stranding mechanism in the present invention, when the bare wire passes through the wire pay-off assembly, the cleaning structure of the wire pay-off assembly cleans the surface of the wire, removing impurities and grease on the wire surface, reducing the resistance of the wire after stranding into strands, ensuring the wire efficiency of the wire, and after the impurities are removed, the wire performance unevenness of local wires is avoided, and problems such as local overheating caused by resistance differences are avoided, ensuring the stable conductivity of the cable during long-term use. At the same time, after removing impurities such as grease and dust, the friction between wires is prevented from decreasing, and it is avoided that the wires are difficult to be tightly stranded. After cleaning, the wire surface is clean, and it can better fit each other during stranding, increasing the stranding tightness and making the cable structure more stable, preventing the stranding from loosening.

[0014] By setting the limiting frame in the present invention, when the wire is payed off from the reel, the pay-off position of the wound wire constantly changes, and the wire shakes. The shaking of the wire drives the limiting frame to deform. The H-shaped limiting frame can deform in all directions, which can buffer the swing of the wire, thereby reducing the swing of the wire and ensuring the tight stranding of the subsequent wire. The wire passes through the annular middle part of the limiting frame and then presses the fixed plate, and the elastic plate deforms, thereby limiting the wire. The elastic plate can buffer the small swing of the wire when the wire swings, further limiting the swing of the wire and further ensuring the tightness during wire stranding.

[0015] By setting the cleaning ring in the present invention, the wire passes through the cleaning ring, and the cleaning ring deforms to wrap the surface of the wire. When the wire passes through, the cleaning ring scrapes the surface of the wire, thereby completing the cleaning of the wire. At the same time, when the wire passes through the cleaning ring, the rubber plate deforms, avoiding the cleaning ring from scratching the wire and preventing the wire from being damaged and affecting the conductivity efficiency after stranding. The two ends of the cleaning ring are embedded inside the rubber plate to strengthen the fixation of the cleaning ring, thereby avoiding the cleaning ring from falling off when cleaning the wire.

[0016] By providing a guiding component, a plurality of guiding plates in the conical shield are evenly distributed, which can guide multiple wires to approach each other and gradually converge into a strand that can pass through the stranding module, ensuring the smooth stranding of the wires. Moreover, the plurality of guiding plates isolate the plurality of wires in a conical shape, preventing them from naturally converging into a cone and causing entanglement with each other.

[0017] By providing a tensioning component, the wires pass through the guiding plates and then through the smoothing cylinder. The plurality of wires pass through the smoothing cylinder in parallel, restricting the wires that are gradually forming a strand to prevent the wires from spreading. At the same time, it ends the tendency of the wires to form a cone, ensuring the smooth stranding of the wires. The two rollers are driven to move up and down, thereby adjusting the tension of the wires to ensure that the tension of the plurality of wires is uniform during stranding and ensuring the stranding quality of the wires. When the wires pass through, the two rollers rotate to ensure the smooth passage of the wires, and the two rollers cooperate with each other to restrict the wires and prevent entanglement between the wires.

An installation plate 37 is fixedly connected to the surface of the driving component 36, and the side of the installation plate 37 away from the driving component 36 is fixedly connected to the top of the bottom plate 1; The driving component 36 drives the wire pay-off component 34, the guiding component 32, and the tensioning component 35 to rotate. The wire pay-off component 34 has a cleaning structure, and the stranding module 31 has a stranding structure; A plurality of bare wires are wound around the wire pay-off component 34, and then the bare wires are pulled. The wires sequentially pass through the wire pay-off component 34, the guiding component 32, and the tensioning component 35. Finally, several wires converge into the stranding module 31. The stranding module 31 strands several wires. When the bare wires pass through the wire pay-off component 34, the cleaning structure of the wire pay-off component 34 cleans the surface of the wires, removing impurities and grease on the wire surface, reducing the resistance of the wires after stranding, ensuring the wire efficiency of the wires, and after the impurities are removed, the wire performance unevenness of local wires is avoided, and problems such as local overheating caused by resistance differences are avoided, ensuring the stable conductivity of the cable during long-term use. At the same time, after removing impurities such as grease and dust, the reduction of the friction force between the wires is avoided, and the difficulty of tightly stranding the wires is avoided. After cleaning, the wire surface is clean, and it can better fit with each other during stranding, increasing the stranding tightness, making the cable structure more stable, and preventing the stranding from loosening.

[0022] The wire pay-off component 34 includes an installation base 341, which is fixedly connected to the top of the bottom plate 1. The inner side of the installation base 341 is rotatably connected to a wire pay-off cylinder 342. The inner side of the wire pay-off cylinder 342 is fixedly connected to a wire pay-off shaft 343. The side of the wire pay-off cylinder 342 away from the installation base 341 is fixedly connected to a wire pay-off seat 344. A plurality of wire pay-off seats 344 are evenly distributed along the circumferential direction of the wire pay-off cylinder 342. One side of each of the plurality of wire pay-off seats 344 close to the wire pay-off shaft 343 is rotatably connected to a winding drum 345 through a rotating rod.

[0023] On one side of the wire reel 342 away from the mounting base 341, there are several rod bodies 346 fixedly connected. The rod bodies 346 are arranged at the intervals between several wire guiding seats 344. On the side of the rod body 346 away from the wire reel 342, there is a fixed outer ring 347, and the inner side surface of the fixed outer ring 347 is fixedly connected to the inner side surface of the rod body 346.

The limiting frames 348 are evenly distributed along the circumferential direction of the fixed outer ring 347. The limiting frame 348 is set in a shape similar to the letter "H", and the center of the limiting frame 348 is annular. Pass the wire through the limiting frame 348. When the wire is paid out from the reel 345, the paying-out position of the wound wire changes continuously, the wire vibrates, and the vibration of the wire drives the deformation of the limiting frame 348. The limiting frame 348 in the shape similar to the letter "H" can deform in all directions, can buffer the swing of the wire, and thus reduce the swing of the wire to ensure the tight twisting of the subsequent wire.

[0024] Inside the annular part of the limiting frame 348, there is a fixed plate 3410. The fixed plates 3410 are evenly distributed along the circumferential direction of the inner side surface of the annular part of the limiting frame 348. On the sides of several fixed plates 3410 away from each other, there are several elastic plates 3411, and the elastic plates 3411 are respectively fixedly connected to the four corners of the fixed plate 3410.

The wire passes through the cleaning ring 3414, and the cleaning ring 3414 is deformed to wrap the surface of the wire. When the wire passes through, the cleaning ring 3414 scrapes the surface of the wire, thus completing the cleaning of the wire. At the same time, when the wire passes through the cleaning ring 3414, the rubber plate 3413 is deformed to prevent the cleaning ring 3414 from scratching the wire, avoiding damage to the wire and affecting the conductivity after stranding. And the two ends of the cleaning ring 3414 are embedded in the rubber plate 3413 to strengthen the fixation of the cleaning ring 3414, thereby preventing the cleaning ring 3414 from falling off when cleaning the wire. When the wire passes through the cleaning ring 3414, it drives the cleaning frame 3412 to move, thereby driving the first spring 3415 to deform, so as to buffer the movement of the cleaning frame 3412 and further ensure the smooth stranding of the wire.

After the wire passes through the limiting frame 348, it passes through a plurality of guiding plates 323 in sequence. The plurality of guiding plates 323 in the conical protective cover 321 are evenly distributed, which can guide multiple wires so that they approach each other and gradually converge into a strand that can pass through the stranding module 31, ensuring the smooth stranding of the wire. And the plurality of guiding plates 323 isolate a plurality of wires in a conical shape, preventing them from naturally converging into a cone and causing entanglement with each other.

One end of the second spring 359 away from the sliding seat 358 is fixedly connected to the side of the rotating seat 354 close to the sliding seat 358 and away from the roller 355. When the expansion link 356 is started, the expansion link 356 drives the rotating seat 354 to move, drives the roller 355 to move, drives the wire to move, thereby driving the other roller 355 and the other rotating seat 354 to move, and finally drives the sliding rod 357 to slide inside the sliding seat 358. At the same time, the second spring 359 deforms, thereby squeezing the wire to adjust the tension of the wire during stranding. When the wire passes through, the two rollers 355 rotate to ensure the smooth passing of the wire, and the two rollers 355 cooperate with each other to limit the wire and prevent entanglement between the wires.

[0030] The driving assembly 36 includes a motor 361, the motor 361 is fixedly connected to the inner side surface of the mounting plate 37, a rotating shaft 362 is fixedly connected to one side of the motor 361 close to the wire pay-off reel 342, the rotating shaft 362 is fixedly connected to the output end of the motor 361, and one end of the rotating shaft 362 away from the motor 361 is fixedly connected to one end of the wire pay-off shaft 343 located inside the wire pay-off reel 342. When the motor 361 is started, the output end of the motor 361 drives the rotating shaft 362 to rotate, thereby driving the wire pay-off shaft 343, the guide shaft 322, and the tension shaft 351 to rotate. The wire pay-off shaft 343 drives the wire pay-off reel 342 and the components fixed on the wire pay-off reel 342 and the wire pay-off shaft 343 to rotate, and further drives the wire to rotate slowly. The stranding module 31 drives the wire to rotate and winds the stranded wire from the end away from the motor 361, gradually completing the stranding of the wire.

[0031] During use, the bare wire is wound around the reel 345, and the wire passes through the cleaning frame 3412, the limiting frame 348, the guide plate, and the smooth cylinder 352 in sequence, and finally penetrates into the stranding module 31, and winds the stranded wire from the end away from the motor 361. When the motor 361 is started, the output end of the motor 361 drives the rotating shaft 362 to rotate, thereby driving the wire pay-off shaft 343, the guide shaft 322, and the tension shaft 351 to rotate. The wire pay-off shaft 343 drives the wire pay-off reel 342 and the components fixed on the wire pay-off reel 342 and the wire pay-off shaft 343 to rotate, and further drives the wire to rotate slowly. The stranding module 31 drives the wire to rotate, and cooperates with the winding of the stranded wire from the end away from the motor 361, gradually completing the stranding of the wire. The wire passes through the cleaning ring 3414, and the cleaning ring 3414 deforms to wrap the surface of the wire. When the wire passes through, the cleaning ring 3414 scrapes the surface of the wire, thereby completing the cleaning of the wire. When the wire passes through the cleaning ring 3414, it drives the cleaning frame 3412 to move, thereby driving the first spring 3415 to deform, so as to buffer the movement of the cleaning frame 3412. The wire passes through the annular middle part of the limiting frame 348, and then presses the fixing plate 3410, and the elastic plate 3411 deforms, thereby limiting the wire. The wire penetrates into one end of the smooth cylinder 352, then passes through the interval between the two rollers 355, and then penetrates out from the other end of the smooth cylinder 352. When the telescopic rod 356 is started, the telescopic rod 356 drives the rotating seat 354 to move, drives the roller 355 to move, drives the wire to move, thereby driving the other roller 355 and the other rotating seat 354 to move, and finally drives the sliding rod 357 to slide inside the sliding seat 358, and at the same time the second spring 359 deforms to press the wire, adjusting the tension of the wire during stranding, so as to adjust the tension of the wire. When the wire passes through, the two rollers 355 rotate to ensure the smooth passing of the wire.
