Optoelectronic cables are generally made by twisting multiple cables together and then wrapping an insulating sheath around their circumference.

[0003] Multiple cables are twisted into a single cable using a twisting machine. The twisting machine includes a pay-off unit, a splitting die unit, and a twisting die unit. The pay-off unit releases multiple cables (wires) and filler ropes. After being guided by the splitting die unit, the multiple cables and filler ropes enter the twisting die unit, where they are twisted into a single cable.

[0069] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0070] As described in the background section of this application, multiple cables are twisted into a single cable using a twisting machine. The twisting machine includes a pay-off unit, a splitting die unit, and a twisting die unit. The pay-off unit dispenses multiple cables (wires) and filler ropes. After being guided by the splitting die unit, the multiple cables and filler ropes enter the twisting die unit, where they are twisted into a single cable.

[0071] The inventors of this application have discovered that the wire feeding unit of existing stranding machines generally adopts a cradle-type structure with a de-twisting mechanism. The dancing wheel does not rotate relative to the rotating axis, resulting in a very large machine size and rotational inertia, leading to low production efficiency. Furthermore, the cable bends many times and at large angles on the moving wheel (dancing wheel), which can easily cause damage to the cable. In addition, the lack of tension feedback control results in poor stability of tension control over the cable.

[0072] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0073] Example 1

[0074] Figure 1 This is a schematic diagram of the winch wire feeding device in Embodiment 1 of the present invention. Figure 2 As in Embodiment 1 of the present invention Figure 1 A magnified view of a portion of the image. Figure 3 This is a schematic diagram of the winch in Embodiment 1 of the present invention. Figure 4 This is a schematic diagram of the wire guiding mechanism in Embodiment 1 of the present invention. Figure 5 This is a schematic diagram of the filling rope feeding mechanism in Embodiment 1 of the present invention. Figure 6 This is a schematic diagram of the dance wheel mechanism in Embodiment 1 of the present invention. Figure 7 This is a schematic diagram of the cable delivery mechanism in Embodiment 1 of the present invention. Figure 8 This is a schematic diagram of the driving mechanism in Embodiment 1 of the present invention. Figures 1 to 8 As shown, the winch wire feeding device of this embodiment includes: a frame 1, a winch 2, a filling rope feeding mechanism 3, a dance wheel mechanism 4, a cable feeding mechanism 5, a wire guiding mechanism 6, a drive mechanism 7, and a controller.

[0075] The rack 1 is fixed in place.

[0076] The winch 2 is rotatably mounted on the frame 1. The winch 2 includes: a left hollow main shaft 21, a right hollow main shaft 22, a left disc 23, a right disc 24, and a connecting beam 25.

[0077] The left hollow spindle 21 and the right hollow spindle 22 are rotatably mounted on the frame 1 via bearing seats. The left hollow spindle 21 and the right hollow spindle 22 are arranged on the frame 1 at left and right intervals and located on the same horizontal plane. The central axis of the left hollow spindle 21 and the central axis of the right hollow spindle 22 coincide with each other.

[0078] A collector ring 201 is fitted on the left end of the left hollow spindle 21. The collector ring 201 is used to connect to an external power source to realize the transmission of internal and external power sources and electrical signals.

[0079] The left disc 23 is fixedly mounted on the left hollow main shaft 21, located at the right end of the left hollow main shaft 21. The right disc 24 is fixedly mounted on the right hollow main shaft 22, located at the left end of the right hollow main shaft 22. The left disc 23 and the right disc 24 are fixedly connected by multiple connecting beams 25, so that the left hollow main shaft 21, the right hollow main shaft 22, the left disc 23, the right disc 24 and the connecting beams 25 form an integral auger 2, which can rotate synchronously on the frame 1.

[0080] The wire guiding mechanism 6 is set on the left hollow main shaft 21 and the right hollow main shaft 22, located between the left disk 23 and the right disk 24. The left and right ends of the wire guiding mechanism 6 are fixedly connected to the left hollow main shaft 21 and the right hollow main shaft 22 respectively. When the auger 2 rotates, it drives the wire guiding mechanism 6 to rotate together.

[0081] There are multiple filling rope feeding mechanisms 3, dance wheel mechanisms 4, and cable feeding mechanisms 5, and the number of filling rope feeding mechanisms 3, dance wheel mechanisms 4, and cable feeding mechanisms 5 is the same.

[0082] The filler rope feeding mechanism 3 is located on the right end face of the left disc 23 of the winch 2. Multiple filler rope feeding mechanisms 3 are evenly distributed along the circumference on the left disc 23. The filler rope feeding mechanism 3 is used to place and fix the filler rope reel and feed out the filler rope. Under the traction of the traction mechanism, the fed filler rope passes through the wire guiding mechanism 6 and the right hollow main shaft 22, and finally exits from the right end of the right hollow main shaft 22.

[0083] Multiple cable feeding mechanisms 5 are set on the left end face of the right disc 24 of the winch 2. The multiple cable feeding mechanisms 5 are evenly distributed on the right disc 24 along the circumferential direction. The cable feeding mechanism 5 is used to place and fix the cable reel and feed out the cable.

[0084] The dance wheel mechanism 4 is located on the right end face of the left disc 23, at the connection between the left disc 23 and the cable guiding mechanism 6. Multiple dance wheel mechanisms 4 are evenly distributed along the circumference on the left disc 23. Multiple cables released by multiple cable feeding mechanisms 5 are guided by the traction mechanism and then enter the cable guiding mechanism 6 after passing through multiple dance wheel mechanisms 4, and finally exit from the right end of the right hollow main shaft 22.

[0085] The drive mechanism 7 is mounted on the frame 1 and is connected to the left hollow main shaft 21 of the auger 2. The drive mechanism 7 is used to drive the left hollow main shaft 21 to rotate, that is, the drive mechanism 7 is used to drive the entire auger 2 to rotate.

[0086] The controller (not shown in the figure) is mounted on the frame 1. The dance wheel mechanism 4, the cable feeding mechanism 5 and the drive mechanism 7 are electrically connected to the controller. The controller controls the operation of the dance wheel mechanism 4, the cable feeding mechanism 5 and the drive mechanism 7 according to the preset program.

[0087] As can be seen from the above, the winch wire feeding device of this embodiment comprises a frame, a winch, a filler rope feeding mechanism, a dancing wheel mechanism, a cable feeding mechanism, a wire guiding mechanism, a drive mechanism, and a controller. The winch is rotatably mounted on the frame. Multiple filler rope feeding mechanisms are arranged on the left disc of the winch, multiple cable feeding mechanisms are evenly arranged on the right disc of the winch, multiple dancing wheel mechanisms are evenly arranged on the left disc of the winch, the wire guiding mechanism is located between the left and right hollow main shafts of the winch, and the drive mechanism is mounted on the frame and connected to the winch for transmission. This winch wire feeding device of this embodiment adopts a non-twist structure, with the filler rope feeding mechanism, dancing wheel mechanism, cable feeding mechanism, and wire guiding mechanism respectively mounted on the winch and rotating with it. The cable released by the cable release mechanism is guided by the dance wheel mechanism and then enters the cable guide mechanism. The filler rope released by the filler rope release mechanism also enters the cable guide mechanism, and then is output from the right hollow main shaft of the winch. The structure is simple and compact, and the winch can run at a speed of up to 100 rpm. The dance wheel mechanism rotates with the winch, and the cable bends at a small angle when winding on the moving wheel (dance wheel), which will not cause damage to the cable. The main shaft adopts a hollow structure, and the cable and filler rope can be threaded inside the hollow shaft, which greatly simplifies the cable travel path.

[0088] Optional, such as Figure 1 , Figure 2 , Figure 4 As shown, the winding wire feeding device in this embodiment includes a wire guiding mechanism 6 comprising a circular frame 61 and a wire guiding disc 62.

[0089] The circular frame 61 is positioned between the left hollow spindle 21 and the right hollow spindle 22. The left and right ends of the circular frame 61 are fixedly connected to the left hollow spindle 21 and the right hollow spindle 22, respectively. When the left hollow spindle 21 rotates, it drives the circular frame 61 to rotate together.

[0090] Multiple wire guides 62 are provided, and the multiple wire guides 62 are arranged at intervals on the inner cross section of the circular frame 61.

[0091] The cable guide 62 has multiple ceramic eyelets 621, which are evenly distributed along the circumference of the cable guide 62. The number of ceramic eyelets 621 corresponds one-to-one with the number of the filling rope feeding mechanism 3, the cable feeding mechanism 5, and the dance wheel mechanism 4. After the multiple filling ropes released by the multiple filling rope feeding mechanisms 3 enter the circular frame 61, they pass through the multiple ceramic eyelets 621 of the cable guide 62. Similarly, after the multiple cables released by the multiple cable feeding mechanisms 5 are guided by the dance wheel mechanism 4, they enter the circular frame 61 and also pass through the multiple ceramic eyelets 621 of the cable guide 62. Finally, the filling ropes and cables are output from the right end of the right hollow main shaft 22.

[0092] In this embodiment, multiple sets of filler ropes and cables are threaded through multiple ceramic holes in the cable guide spool. The cable guide spool supports and lifts the filler ropes and cables, preventing tension fluctuations caused by gravity and centrifugal force.

[0093] Furthermore, in this embodiment, the winding mechanism 6 of the winding wire feeding device also includes a first guide wheel 63.

[0094] Multiple first guide wheels 63 are provided, and the number of multiple first guide wheels 63 corresponds to the number of multiple ceramic eyes on the wire guide plate 62.

[0095] The first guide wheel 63 is located at the right end of the circular frame 61. Multiple first guide wheels 63 are evenly distributed along the circumference on the circular frame 61. The filling rope and cable that pass through the ceramic eye 621 of the wire guide spool 62 are guided by the first guide wheel 63 and enter the right hollow main shaft.

[0096] Furthermore, such as Figure 1 , Figure 5 As shown, the winding wire feeding device in this embodiment includes a filling rope feeding mechanism 3 comprising: a first feeding shaft 31 and a second guide wheel 32.

[0097] The first feed shaft 31 is rotatably mounted on the left disc 23 of the winch 2 via a connector. The filler rope reel 33 is detachably fixed to the first feed shaft 31 via inner and outer centers. The first feed shaft 31 releases the filler rope when it rotates.

[0098] The second guide wheel 32 is mounted on the left disc 23, located within the annular frame 61 of the wire guiding mechanism 6. The second guide wheel 32 and the ceramic eye 621 on the wire guiding disc 62 are at approximately the same horizontal level. Under the traction of the traction mechanism, the filling rope released from the filling rope disc 33 passes around the second guide wheel 32. After being guided by the second guide wheel 32, the filling rope passes through the ceramic eye 621 of the wire guiding disc 62, and then is guided by the first guide wheel 63 before entering the right hollow main shaft.

[0099] Furthermore, in this embodiment, the winding wire release device and the filling rope release mechanism 3 also include a hysteresis brake 34.

[0100] The hysteresis brake 34 is electrically connected to the controller. The hysteresis brake 34 includes a rotor 341 and a stator 342.

[0101] The rotor 341 is fixedly mounted on the first pay-off shaft 31 via a connecting component (such as a coupling). When the first pay-off shaft 31 rotates, it drives the rotor 341 to rotate together. The stator 342 is fixedly mounted on the left disc 23 and is sleeved on the outer circumference of the rotor 341. The stator 342 does not rotate with the first pay-off shaft 31.

[0102] In this embodiment, when the hysteresis brake is energized, the rotor rotates relative to the stator, generating electromagnetic resistance between the stator and rotor. When the filler rope is dragged out, the first release shaft also experiences resistance, resulting in a certain tension in the filler rope during release. Simultaneously, by adjusting the voltage of the hysteresis brake, the electromagnetic resistance between the stator and rotor can be adjusted, thus adjusting the tension of the filler rope.

[0103] Furthermore, such as Figure 1 , Figure 7 As shown, the cable feeding device in this embodiment includes a cable feeding mechanism 5 comprising a feeding motor 51, a driving center 52, and a moving center 53.

[0104] The wire feeding motor 51 is mounted on the right disc 24 via a connector, and the wire feeding motor 51 is electrically connected to the controller.

[0105] The driving tip 52 and the moving tip 53 are rotatably mounted on the right disc 24. The driving tip 52 and the moving tip 53 are spaced apart and coaxially arranged. The driving tip 52 is connected to the output shaft of the wire feeding motor 51 via the conveyor belt 54.

[0106] The drive tip 52 and the moving tip 53 are used to install and fix the cable reel. The cable feeding motor 51 drives the drive tip 52 and the cable reel to rotate synchronously, and the cable reel feeds out the cable when it rotates.

[0107] Furthermore, such as Figure 1 , Figure 6 As shown, the winch wire feeding device in this embodiment, the dance wheel mechanism 4 includes: a fixed plate 41, a tension sensor 42, and a dance wheel 43.

[0108] The fixing plate 41 is set on the left disc 23 of the winch 2.

[0109] Tension sensor 42 is mounted on fixed plate 41, and dance wheel 43 is mounted on the shaft end of tension sensor 42. Tension sensor 42 is electrically connected to controller.

[0110] In this embodiment, the controller controls the opening and closing of the cable feeding motor to control the cable reel to feed the cable. The fed cable is wound around the dance wheel and guided by the dance wheel before entering the cable guiding mechanism. A tension sensor on the dance wheel detects the cable tension in real time and transmits the detection signal to the controller. The controller receives the tension detection signal from the tension sensor and controls the speed of the cable feeding motor in real time based on the tension detection signal, achieving real-time and precise control of the cable tension. Unlike traditional cable feeding units where the cable is wound among numerous guide wheels such as movable wheels, fixed wheels, and tension sensor wheels, this embodiment simplifies the process to a single dance wheel (movable guide wheel) through a reasonable mechanism layout design, greatly simplifying the cable's travel path and making tension detection more direct and accurate.

[0111] Furthermore, the winding wire feeding device and the dance wheel mechanism 4 in this embodiment also include: a fixing block 44, an adjusting bolt 45, a spring 46, a guide rail 47, and a slider 48.

[0112] The fixing block 44 and the guide rail 47 are respectively mounted on the fixing plate 41.

[0113] The fixing block 44 is provided with a threaded through hole, and the adjusting bolt 45 is rotatably inserted into the threaded through hole of the fixing block 44, and the adjusting bolt 45 is threadedly connected to the fixing block 44.

[0114] The slider 48 is slidably mounted on the guide rail 47.

[0115] One end of the spring 46 is connected to the adjusting bolt 45, and the other end of the spring 46 is fixedly connected to the slider 48.

[0116] Tension sensor 42 is mounted on slider 48, and dance wheel 43 is mounted on the shaft end of tension sensor 42.

[0117] In this embodiment, rotating the adjusting bolt causes the slider to move on the guide rail via a spring. As the slider moves, it causes the dance wheel and tension sensor to move together, thus adjusting the cable tension when needed.

[0118] Furthermore, such as Figure 1 , Figure 8 As shown, the winding wire feeding device in this embodiment includes a drive mechanism 7 comprising a drive motor 71, a drive pulley 72, and a timing belt 73.

[0119] A driven pulley 211 is fitted on the left hollow main shaft 21.

[0120] The drive motor 71 is mounted on the frame 1 and electrically connected to the controller. The drive pulley 72 is mounted on the output shaft of the drive motor 71.

[0121] The driving pulley 72 and the driven pulley 211 are connected by a synchronous belt 73.

[0122] In this embodiment, when the drive motor rotates, it drives the driven pulley and the left hollow main shaft to rotate, that is, it drives the winch 2 to rotate.

[0123] Example 2

[0124] Figure 9 This is a schematic diagram of the stranding machine in Embodiment 2 of the present invention.

[0125] like Figure 9 As shown, this embodiment also provides a stranding machine, which includes: a wire separating mold mechanism 8, a stranding mold mechanism 9, and a wire feeding device as described in the above embodiment.
