Description

Technical Field

[0001] This invention relates to the technical field of fully automatic stranding equipment for composite cable production, specifically to a fully automatic stranding device and method for composite cable production. Background Technology

[0002] Stranded wire refers to two or more strands of wire twisted together. The most common types are copper and aluminum. Copper and aluminum wires can be twisted into conductors, cores, and inner cores of various types of wires and cables with different cross-sections. The stranding devices used in stranding are mostly composed of a stranding mechanism and a winding mechanism, which are used to wind the wire and collect the processed inner core, thus completing the stranding process.

[0003] In existing fully automatic stranding devices, the shaft that holds the copper wires rotates freely during the stranding process. When the copper wires are stranded rapidly, it is not easy to control the speed of the shaft. When the shaft rotates at a high speed and the output of copper wires is high, the tension of the copper wires is likely to be low. Low tension can easily lead to several copper wires becoming entangled and overlapping. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] Furthermore, a tightening mechanism is provided directly above the equipment base. The tightening mechanism includes a rotating shaft fixedly connected to the end of the driven gear away from the rotating cylinder. A tightening disc is fixedly connected to the end of the rotating shaft away from the driven gear. Several small holes are opened on the tightening disc. Copper wires pass through the small holes on the tightening disc. A tightening plate is fixedly connected directly above the equipment base. Small holes are opened on the tightening plate.

[0010] Furthermore, a cable winding mechanism is provided directly above the equipment base. The cable winding mechanism includes a bevel gear 1 fixedly connected to the end of the rotating shaft away from the drive motor. Several side fixing plates are fixedly connected to the top of the equipment base. A rotating shaft 1 is rotatably connected to the side fixing plates. A bevel gear 2 is fixedly connected to the middle of the rotating shaft 1. The bevel gear 1 meshes with the rotating shaft 1. A drive belt is driven to one end of the rotating shaft 1. A cable winding wheel is rotatably connected to the side wall of the side fixing plate. A rotating shaft 2 is driven to the end of the drive belt away from the rotating shaft 1. A cable winding wheel is fixedly connected to the end of the rotating shaft 2 away from the drive belt. The copper wire wheel forms the finished cable by passing through one side of the tightening plate.

[0011] Furthermore, a control mechanism is provided on one side of the driven gear. The control mechanism includes several centrifugal sliding grooves opened on the side of the driven gear away from the rotating cylinder, several clamping sliding grooves opened on the side of the driven gear away from the rotating cylinder, centrifugal sliding blocks slidably connected in the centrifugal sliding grooves, several extrusion sliding blocks slidably connected in the clamping sliding grooves, and several linkage rods rotatably connected to one end of the centrifugal sliding block. The end of the linkage rod away from the centrifugal sliding block is rotatably connected to the extrusion sliding block.

[0012] Furthermore, the control mechanism also includes a compression spring disposed inside the clamping sliding groove.

[0013] Furthermore, an auxiliary mechanism is provided on the centrifugal sliding block. The auxiliary mechanism includes a second linkage rod rotatably connected to the side of the centrifugal sliding block away from the centrifugal sliding groove. A connecting rod is rotatably connected to the end of the second linkage rod away from the centrifugal sliding block, and the connecting rod is fixedly connected to one end of the second sliding block.

[0014] The method for producing composite cables using a fully automated stranding device includes the following steps:

[0015] S1: Rotary stranding. The wire feeding shaft on the driven gear rotates with the driven gear. At this time, the copper wire wheel on the wire feeding shaft rotates. The copper wire on the copper wire wheel passes through the reversing wheel in the sliding frame. Then the copper wire passes through the small hole on the tightening plate. Several copper wires pass through the small hole on the tightening plate and then converge into the small hole on the tightening plate. This setting helps to limit the number of copper wires and prevent them from getting tangled during the stranding process. The copper wires on the tightening plate are driven by the rotation of the rotary stranding mechanism to form the finished cable.

[0016] S2: Tension tightening. By setting the reversing wheel in the tensioning mechanism, the tension spring squeezes the reversing wheel on the sliding block one. The reversing wheel is squeezed by the elastic force of the tension spring and slides forward along the sliding frame. This setting is conducive to tightening the copper wire.

[0017] S3: Product winding. The rotation of the rotating shaft drives the rotation of bevel gear one, which in turn drives the rotation of shaft one on bevel gear two. The rotation of shaft one drives the rotation of shaft two at one end of the transmission belt, which in turn drives the rotation of cable winding wheel. The rotation of cable winding wheel realizes the winding of the finished cable.

[0018] S4: Control the rotation speed. The centrifugal force of the centrifugal sliding block is used to slide outward along the centrifugal sliding groove, causing the friction block in the control mechanism to generate friction with the surface of the wire feeding shaft, thereby damping the wire feeding shaft during rotation.

[0019] The present invention has the following beneficial effects:

[0020] (1) In this invention, by setting a control mechanism, when the driven gear rotates at a relatively high speed, the centrifugal sliding block slides outward along the centrifugal sliding groove under the action of centrifugal force. The centrifugal sliding block drives the compression sliding block at one end of the linkage rod to slide along the clamping sliding groove towards the end closer to the wire feeding shaft. The compression sliding block drives the telescopic rod to retract. At this time, the pressure spring on the telescopic rod is compressed and retracted. When the pressure spring retracts, the elastic force of the pressure spring increases. The compression spring controls the slider to slide outward along the friction block. At this time, the ball moves away from the surface of the wire feeding shaft. The side of the friction block close to the wire feeding shaft generates sliding friction with the surface of the wire feeding shaft. When the friction block and the surface of the wire feeding shaft are in contact, the friction block generates sliding friction. When friction occurs on the surface, the wire feeding shaft is constrained, increasing its rotational damping. This design helps control the shaft's rotational speed, preventing it from rotating too fast and thus avoiding excessive copper wire output from the wire sheave. When the driven gear rotates slowly, the centrifugal sliding block has a small displacement, resulting in a small compression of the pressure spring. At this point, the balls on the control slider maintain rolling contact with the wire feeding shaft surface, while the friction block does not contact the shaft surface. This design helps ensure minimal friction on the wire feeding shaft under low-speed winding of the driven gear, minimizing the heat generated by the rolling friction between the balls and the shaft.

[0021] (2) In this invention, when the fully automatic stranding device is used, the drive motor is started, the output end of the drive motor drives the rotating shaft to rotate, the rotating shaft rotates and drives the active gear to rotate, the active gear rotates and drives the passive gear to rotate. At this time, the passive gear drives the connecting column at one end of the rotating cylinder to rotate. By setting the connecting column at one end of the rotating cylinder, it is beneficial to ensure the stable rotation of the passive gear on the rotating cylinder. The wire feeding shaft set on the passive gear follows the rotation of the passive gear. At this time, the copper wire wheel on the wire feeding shaft rotates, and the copper wire on the copper wire wheel passes through the reversing wheel in the sliding frame. At this time, the copper wire passes through the small hole on the tightening plate. Several copper wires pass through the small hole on the tightening plate and converge into the small hole on the tightening plate. This setting is beneficial to limit the several copper wires and prevent the several copper wires from tangling together during the stranding process. The several copper wires on the tightening plate are driven by the rotation of the rotating stranding mechanism to form the finished cable.

[0022] (3) In this invention, by setting a tensioning mechanism, when several copper wires are twisted, the copper wires are pulled to generate tension. In order to ensure that the copper wires always maintain a large tension, a reversing wheel is set in the tensioning mechanism. The tensioning spring squeezes the reversing wheel on the sliding block. The reversing wheel is squeezed by the elastic force of the tensioning spring and slides forward along the sliding frame. This setting is conducive to tightening the copper wires and avoiding the copper wires from becoming loose due to insufficient tension. This ensures that several copper wires are always tightened during the twisting process and ensures the twisting quality of the device.

[0023] (4) In this invention, by setting an auxiliary mechanism, when the passive gear rotates at a relatively fast speed, the centrifugal sliding block slides outward along the centrifugal sliding groove under the action of centrifugal force. The centrifugal sliding block drives the connecting rod at one end of the linkage rod two to move. The connecting rod drives the sliding block two to squeeze the tension spring along the sliding frame. At this time, the tension spring is squeezed and contracted by the sliding block two, and the elastic force of the sliding block two increases. Then the squeezing force of the sliding block two on the sliding block one increases, and the squeezing force of the sliding block two on the copper wire of the reversing wheel increases. This setting is conducive to further tightening the copper wire on the reversing wheel and further increasing the tension of the copper wire.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

An auxiliary gear 203 is fixedly connected to the end of the rotating cylinder 14 near the connecting column 12, and a driven gear 204 is fixedly connected to the end of the rotating cylinder 14 away from the connecting column 12. The driven gear 204 meshes with the driving gears 202. Several wire feeding shafts 205 are rotatably connected to the side of the driven gear 204 away from the rotating cylinder 14. Copper wire is disposed on a copper wire reel 206. The copper wire wheel 206 has copper wire 207 on it. The function of this component is to start the drive motor 13 when the fully automatic stranding device is used. The output end of the drive motor 13 drives the rotating shaft 201 to rotate. The rotation of the rotating shaft 201 drives the drive gear 202 to rotate. The rotation of the drive gear 202 drives the driven gear 204 to rotate. At this time, the driven gear 204 drives the connecting post 12 at one end of the rotating cylinder 14 to rotate. By setting the connecting post 12 at one end of the rotating cylinder 14, it is beneficial to ensure the stable rotation of the driven gear 204 on the rotating cylinder 14.

[0041] A tensioning mechanism 3 is provided on the driven gear 204. The tensioning mechanism 3 includes several sliding frames 301 fixedly connected to the side of the driven gear 204 away from the rotating cylinder 14.

A reversing wheel 305 is rotatably connected to the end of the sliding block 302 away from the tension spring 303. The copper wire 207 is driven by the reversing wheel 305. The function of this component is... By setting up a tensioning mechanism 3, when several copper wires 207 are twisted, the copper wires 207 are pulled and generate tension. In order to ensure that the copper wires 207 maintain a large tension at all times, a reversing wheel 305 is set in the tensioning mechanism 3. The tensioning spring 303 presses the reversing wheel 305 on the sliding block 302. The reversing wheel 305 is pressed by the elastic force of the tensioning spring 303 and slides forward along the sliding frame 301. This setting helps to tighten the copper wires 207 and avoid the copper wires 207 from becoming too loose due to insufficient tension. This ensures that the several copper wires 207 are always taut during the twisting process and ensures the twisting quality of the device.

[0042] A tightening mechanism 4 is provided directly above the equipment base 1. The tightening mechanism 4 includes a rotating shaft 401 fixedly connected to the end of the driven gear 204 away from the rotating cylinder 14. A tightening disc 402 is fixedly connected to the end of the rotating shaft 401 away from the driven gear 204. The tightening disc 402 has several small holes, and copper wires 207 pass through the small holes in the tightening disc 402. A tightening plate 403 is fixedly connected directly above the equipment base 1. The tightening plate 403 has small holes. The function of this component is to be installed on the driven gear 204. The wire feeding shaft 205 rotates following the driven gear 204. At this time, the copper wire wheel 206 on the wire feeding shaft 205 rotates, and the copper wire 207 on the copper wire wheel 206 passes through the reversing wheel 305 in the sliding frame 301. Then, the copper wire 207 passes through the small hole on the tightening plate 402. Several copper wires 207 pass through the small hole on the tightening plate 402 and then converge into the small hole on the tightening plate 403. This setting helps to limit the movement of several copper wires 207 and prevent them from getting tangled together during the twisting process.

[0043] A cable winding mechanism 5 is provided directly above the equipment base 1. The cable winding mechanism 5 includes a bevel gear 501 fixedly connected to the end of the rotating shaft 201 away from the drive motor 13. Several side fixing plates 502 are fixedly connected to the top of the equipment base 1. A rotating shaft 503 is rotatably connected to the side fixing plate 502. A bevel gear 504 is fixedly connected to the middle of the rotating shaft 503. The bevel gear 501 meshes with the rotating shaft 503. A drive belt 505 is drivenly connected to one end of the rotating shaft 503. A cable storage wheel 507 is rotatably connected to the side wall of the side fixing plate 502. The drive belt 505 is located away from the rotating shaft 501. One end of component 3 is connected to a rotating shaft 506. The end of the rotating shaft 506 away from the transmission belt 505 is fixedly connected to a cable storage wheel 507. The copper wire wheel 206 forms a finished cable 508 through one side of the tightening plate 403.

[0044] Example 2 differs from Example 1 in that: Figure 1 - Figure 10As shown, a control mechanism 6 is provided on one side of the passive gear 204. The control mechanism 6 includes several centrifugal sliding grooves 601 opened on the side of the passive gear 204 away from the rotating cylinder 14. Several clamping sliding grooves 602 are opened on the side of the passive gear 204 away from the rotating cylinder 14. Centrifugal sliding blocks 603 are slidably connected in the centrifugal sliding grooves 601. Several pressing sliding blocks 604 are slidably connected in the clamping sliding grooves 602. Several linkage rods 605 are rotatably connected to one end of the centrifugal sliding block 603. The end of the linkage rod 605 away from the centrifugal sliding block 603 is rotatably connected to the pressing sliding block 604.

[0045] The control mechanism 6 also includes a compression spring 606 disposed inside the clamping sliding groove 602. A telescopic rod 607 is fixedly connected to one end of the compression sliding block 604 away from the clamping sliding groove 602. A friction block 608 is fixedly connected to one end of the telescopic rod 607 away from the compression sliding block 604. A control slider 609 is slidably connected inside the friction block 608. A pressure spring 610 is fixedly connected to one end of the control slider 609 away from the wire feeding shaft 205. A ball bearing 611 is embedded on the side of the control slider 609 closest to the wire feeding shaft 205. The function of this component is... By setting control mechanism 6, when the driven gear 204 rotates at a relatively high speed, the centrifugal sliding block 603 slides outward along the centrifugal sliding groove 601 under the action of centrifugal force. The centrifugal sliding block 603 drives the pressing sliding block 604 at one end of the linkage rod 605 to slide along the clamping sliding groove 602 towards the end closer to the wire feeding shaft 205. The pressing sliding block 604 drives the telescopic rod 607 to retract. At this time, the pressure spring 610 on the telescopic rod 607 is compressed and retracted. When the pressure spring 610 retracts, the elastic force of the pressure spring 610 increases, and the pressure spring... Spring 610 retracts, controlling slider 609 to slide outward along friction block 608. At this time, ball 611 moves away from the surface of payoff shaft 205. The side of friction block 608 closest to payoff shaft 205 generates sliding friction with the surface of payoff shaft 205. When friction occurs between friction block 608 and the surface of payoff shaft 205, payoff shaft 205 is restrained, increasing rotational damping. This configuration helps control the rotational speed of payoff shaft 205, preventing excessive rotation and avoiding the formation of copper wire wheel 2. The phenomenon of excessive output of copper wire 207 on 06; when the rotation speed of the driven gear 204 is slow, the displacement of the centrifugal sliding block 603 is small, and the contraction of the pressure spring 610 is small. At this time, the ball 611 on the control slider 609 maintains rolling connection with the surface of the wire feeding shaft 205, while the friction block 608 does not contact the surface of the wire feeding shaft 205. This setting helps to ensure that the friction generated by the wire feeding shaft 205 is small under the low-speed winding of the driven gear 204, and the heat generated by the rolling friction between the ball 611 and the wire feeding shaft 205 is small.

[0046] An auxiliary mechanism 7 is provided on the centrifugal sliding block 603. The auxiliary mechanism 7 includes a second linkage rod 701 rotatably connected to the side of the centrifugal sliding block 603 away from the centrifugal sliding groove 601. A connecting rod 702 is rotatably connected to the end of the second linkage rod 701 away from the centrifugal sliding block 603. The connecting rod 702 is fixedly connected to one end of the second sliding block 304. The function of this component is that, by setting up the auxiliary mechanism 7, when the driven gear 204 rotates at a relatively fast speed, the centrifugal sliding block 603 slides outward along the centrifugal sliding groove 601 under the action of centrifugal force. The connecting rod 702 at one end of the linkage rod 701 moves, and the connecting rod 702 drives the sliding block 304 to press the tension spring 303 along the sliding frame 301. At this time, the tension spring 303 is compressed and contracted by the sliding block 304, and the elastic force of the sliding block 304 increases. Therefore, the squeezing force of the sliding block 304 on the sliding block 302 increases, and the squeezing force of the sliding block 302 on the copper wire 207 on the deflector wheel 305 increases. This setting is conducive to further tightening the copper wire 207 on the deflector wheel 305 and further increasing the tension of the copper wire 207.

[0047] The method for producing composite cables using a fully automated stranding device includes the following steps:

[0048] S1: Rotary stranding. The wire feeding shaft 205, which is set on the driven gear 204, rotates with the driven gear 204. At this time, the copper wire wheel 206 on the wire feeding shaft 205 rotates. The copper wire 207 on the copper wire wheel 206 passes through the reversing wheel 305 in the sliding frame 301. Then, the copper wire 207 passes through the small hole on the tightening plate 402. Several copper wires 207 pass through the small hole on the tightening plate 402 and then converge into the small hole on the tightening plate 403. This setting helps to limit the several copper wires 207 and prevent the several copper wires 207 from getting tangled together during the stranding process. The several copper wires 207 on the tightening plate 403 are driven by the rotation of the rotary stranding mechanism 2 to form the finished cable 508.

[0049] S2: Tension tightening. By setting the reversing wheel 305 in the tensioning mechanism 3, the tensioning spring 303 squeezes the reversing wheel 305 on the sliding block 302. The reversing wheel 305 is squeezed by the elastic force of the tensioning spring 303 and slides forward along the sliding frame 301. This setting is conducive to tightening the copper wire 207.

[0050] S3: Product winding. The rotation of the rotating shaft 201 drives the rotation of the first bevel gear 501. The rotation of the first bevel gear 501 drives the rotation of the first shaft 503 on the second bevel gear 504. The rotation of the first shaft 503 drives the rotation of the second shaft 506 at one end of the transmission belt 505. The rotation of the second shaft 506 drives the rotation of the cable winding wheel 507. The rotation of the cable winding wheel 507 realizes the winding of the finished cable 508.

[0051] S4: Control the rotation speed. The centrifugal force of the centrifugal sliding block 603 is used to slide outward along the centrifugal sliding groove 601, causing the friction block 608 in the control mechanism 6 to rub against the surface of the wire feeding shaft 205, thereby causing the wire feeding shaft 205 to be damped during rotation.

[0052] One specific application of this embodiment is:

[0053] When using the fully automatic stranding device, the drive motor 13 is started. The output end of the drive motor 13 drives the rotating shaft 201 to rotate. The rotation of the rotating shaft 201 drives the driving gear 202 to rotate, and the rotation of the driving gear 202 drives the driven gear 204 to rotate. At this time, the driven gear 204 drives the connecting post 12 at one end of the rotating cylinder 14 to rotate. By setting the connecting post 12 at one end of the rotating cylinder 14, it is beneficial to ensure the stable rotation of the driven gear 204 on the rotating cylinder 14. The wire feeding shaft 205 set on the driven gear 204 follows. The driven gear 204 rotates, at which point the copper wire wheel 206 on the wire feeding shaft 205 rotates. The copper wire 207 on the copper wire wheel 206 passes through the reversing wheel 305 inside the sliding frame 301. Then, the copper wire 207 passes through the small hole on the tightening disc 402. Several copper wires 207 pass through the small hole on the tightening disc 402 and then converge into the small hole on the tightening plate 403. This arrangement helps to limit the movement of several copper wires and prevent them from tangling during the twisting process. The several copper wires 207 passing through the tightening plate 403... The rotating stranding mechanism 2 rotates to form a finished cable 508. The rotating shaft 201 rotates, causing the first bevel gear 501 to rotate. The first bevel gear 501 rotates, causing the first shaft 503 on the second bevel gear 504 to rotate. The first shaft 503 rotates, causing the second shaft 506 at one end of the transmission belt 505 to rotate. The second shaft 506 rotates, causing the cable winding wheel 507 to rotate. The cable winding wheel 507 then winds and winds the finished cable 508. By setting a tensioning mechanism 3, when several copper wires 207 are stranded, the copper wires... 207 is pulled to generate tension. In order to ensure that the copper wire 207 always maintains a large tension, a reversing wheel 305 is set in the tensioning mechanism 3. The tension spring 303 squeezes the reversing wheel 305 on the sliding block 302. The reversing wheel 305 is squeezed by the elastic force of the tension spring 303 and slides forward along the sliding frame 301. This setting is conducive to keeping the copper wire 207 taut and avoiding the copper wire 207 from becoming too loose due to insufficient tension. This ensures that several copper wires 207 are taut at all times during the twisting process and ensures the twisting quality of the device.

[0054] By setting control mechanism 6, when the driven gear 204 rotates at a relatively high speed, the centrifugal sliding block 603 slides outward along the centrifugal sliding groove 601 under the action of centrifugal force. The centrifugal sliding block 603 drives the pressing sliding block 604 at one end of the linkage rod 605 to slide along the clamping sliding groove 602 towards the end closer to the wire feeding shaft 205. The pressing sliding block 604 drives the telescopic rod 607 to retract. At this time, the pressure spring 610 on the telescopic rod 607 is compressed and retracted. When the pressure spring 610 retracts, the elastic force of the pressure spring 610 increases, and the retraction of the pressure spring 610 controls the slider 609 to move along the friction... When the friction block 608 slides outward, the ball 611 moves away from the surface of the wire feeding shaft 205. The side of the friction block 608 closest to the wire feeding shaft 205 generates sliding friction with the surface of the wire feeding shaft 205. When the friction block 608 rubs against the surface of the wire feeding shaft 205, the wire feeding shaft 205 is restrained, increasing its rotational damping. This design helps control the rotational speed of the wire feeding shaft 205, preventing it from rotating too fast and avoiding excessive output of copper wire 207 from the copper wire reel 206. When the driven gear 204 rotates at a slower speed... When the displacement of the centrifugal sliding block 603 is small, the contraction of the pressure spring 610 is also small. At this time, the ball 611 on the control slider 609 maintains rolling contact with the surface of the pay-off shaft 205, while the friction block 608 does not contact the surface of the pay-off shaft 205. This arrangement helps to ensure that the friction generated by the pay-off shaft 205 is small under the low-speed winding of the driven gear 204, and the heat generated by the rolling friction between the ball 611 and the pay-off shaft 205 is also small. By setting the auxiliary mechanism 7, when the driven gear 204 rotates at a higher speed, the centrifugal sliding block 603 is subjected to centrifugal force and moves along the centrifugal sliding groove 6. 01 Slides outward, the centrifugal sliding block 603 drives the connecting rod 702 at one end of the linkage rod 701 to move. The connecting rod 702 drives the sliding block 304 to press the tension spring 303 along the sliding frame 301. At this time, the tension spring 303 is compressed and contracted by the sliding block 304, and the elastic force of the sliding block 304 increases. Therefore, the squeezing force of the sliding block 304 on the sliding block 302 increases, and the squeezing force of the sliding block 302 on the copper wire 207 on the reversing wheel 305 increases. This setting is conducive to further tightening the copper wire 207 on the reversing wheel 305 and further increasing the tension of the copper wire 207.
