Description

Technical Field

[0001] This invention relates to a stranding mechanism, and more particularly to an externally powered dual-power rotary traction type stranding mechanism. Background Technology

[0002] A stranding machine is a device used to produce wires and cables by twisting multiple strands of fine wire together to form a single cable. The stranding principle of existing stranding equipment is as follows: multiple strands of wire are released from the wire feeder and introduced into the main shaft of the stranding machine. From the main shaft, they enter the stranding bow or rotating support. The rotation of the stranding bow or rotating support twists the multiple strands together, and finally, the twisted wire is wound into a take-up reel by guide rollers. However, in this type of stranding machine, the core wire traction power is generally located inside the stranding bow or rotating support. The drive motor either rotates with it or is placed inside the rotating support. However, the motor's wires must be connected to the power supply via carbon brushes, making the structure very complex, bulky, with many vulnerable parts, a high failure rate, significant signal interference, and inconvenient control. Summary of the Invention

[0003] The purpose of this invention is to provide an external dual-power rotary traction stranding mechanism, which can use an external power source to pull the core wire forward, while using another external power source to drive the core wire to rotate, thereby achieving the purpose of stranding.

[0004] To achieve the above objectives, the present invention provides an external dual-power rotary traction stranding mechanism comprising a rotating frame, a first guide wheel, a second guide wheel, a first bevel gear, a second bevel gear, a gear set, a first take-up wheel, a first drive mechanism, and a second drive mechanism; the first guide wheel is pivotally connected to a first end of the rotating frame, and the second guide wheel is pivotally connected to a second end of the rotating frame; the first bevel gear is coaxially and rotatably fitted onto the first end of the rotating frame, and the second bevel gear is pivotally connected to the outside of the rotating frame and meshes with the first bevel gear; the first take-up wheel is pivotally connected to the rotating frame; the input gear of the gear set is coaxially fixed with the second bevel gear, and the output gear of the gear set is coaxially fixed with the first take-up wheel; the first drive mechanism drives the first bevel gear to rotate; and the second drive mechanism drives the rotating frame to rotate.

[0005] Compared with existing technologies, this invention features a rotating frame with a first guide wheel, a first take-up wheel, and a second guide wheel sequentially arranged on it. This allows the core wire to pass through these wheels in sequence. A first bevel gear is coaxially fitted onto the rotating frame, and a first drive mechanism drives the first bevel gear to rotate. A second bevel gear and a gear set transmit the power of the first bevel gear to the first take-up wheel, enabling the first take-up wheel to actively pull the core wire forward. Simultaneously, a second drive mechanism drives the rotating frame, allowing the entire frame to rotate around its central axis. This allows the core wire to be twisted while being output forward. Therefore, this invention can use an external power source to pull the core wire forward, while simultaneously using another external power source to drive its rotation, allowing the core wire to move in a 90-degree space in an alternating motion. Its structure is simple, small in size, and very easy to control.

[0006] Preferably, it also includes a feedback wheel, which is rotatably mounted on the rotating frame via an axle, and the axle is slidably mounted on the rotating frame. By slidably mounting the feedback wheel on the rotating frame, the traction speed of the core wire can be monitored and an electrical signal can be fed back to ensure that the feeding motor delivers the core material at a uniform speed.

[0007] Specifically, it also includes an elastic element disposed between the feedback wheel and the wheel axle. By providing the elastic element, and under the tension of the core wire, the feedback wheel can move back and forth, thereby automatically adapting to changes in the tension of the core wire.

[0008] Specifically, it also includes a position sensing device, which is disposed between the wheel axle and the rotating frame to detect the displacement of the feedback wheel. By setting the position sensing device, the position change of the feedback wheel can be automatically monitored, thereby detecting the change in the core wire conveying speed. This speed change can then be fed back to the take-up or pay-off reel motor outside the mechanism through the control system, thereby increasing or decreasing the output speed. This achieves the purpose of automatic control and uniform speed conveying of wire material, thus improving the stability and accuracy of core wire conveying.

[0009] Specifically, the position sensing device includes a displacement sensor and a sensing plate. The external dual-power rotary traction stranded wire mechanism also includes a slip ring. The sensing plate is disposed on the side wall of the rotating frame. The displacement sensor is disposed on the axle and moves closer to or further away from the sensing plate as the axle moves. The slip ring is coaxially and rotatably disposed on the rotating frame and is electrically connected to both the displacement sensor and the sensing plate. Since the displacement sensor and the sensing plate are disposed on the rotating frame, and the rotating frame rotates around its own central axis, it is impossible to transmit the sensing signal in a straight line through a conductor. Therefore, the slip ring is provided to output the sensing signal without affecting the rotation of the rotating frame, ensuring the continuous operation of the position sensing device.

[0010] Preferably, it also includes a second take-up wheel, which is pivotally connected to the rotating frame, and the first take-up wheel and the second take-up wheel are arranged sequentially along the direction from the first end to the second end of the rotating frame.

[0011] Preferably, the device also includes a counterweight, which is disposed on the side of the rotating frame opposite to the second bevel gear. Since the second bevel gear and the gear set are disposed on one side of the rotating frame, the forces on both sides of the rotating frame will be unbalanced. Therefore, the counterweight can balance the forces on both sides of the rotating frame, thereby making the rotating frame rotate more smoothly, with less vibration, and reducing noise, which is beneficial for continuous production and processing.

[0012] Preferably, the rotating frame includes a first rotating shaft, a frame body, and a second rotating shaft. One side of the frame body has a receiving groove communicating with the outside. The first rotating shaft is located at one end of the frame body, and the second rotating shaft is located at the other end of the frame body. By providing the receiving groove, the first take-up wheel can be placed within it, thus facilitating its installation and ensuring the core wire remains within the receiving groove during transport, effectively reducing wind resistance and noise during transmission.

[0013] Preferably, the first drive mechanism includes a first servo motor, a first driving pulley, a first driven pulley, and a first synchronous belt. The first driving pulley is disposed at the output end of the first servo motor, and the first driven pulley is coaxially and rotatably disposed at the first end of the rotating frame, and the first driven pulley is coaxially fixed with the first bevel gear. The first synchronous belt surrounds the first driving pulley and the first driven pulley. By using the first servo motor to drive the first driving pulley, and then transmitting power to the first bevel gear through the first driving pulley, the first synchronous belt, and the first driven pulley, power from outside the rotating frame is transmitted to the inside of the rotating frame to drive the first take-up wheel to rotate, thereby achieving the purpose of actively pulling the core wire.

[0014] Preferably, the second drive mechanism includes a second servo motor, a second driving pulley, a second driven pulley, and a second synchronous belt. The second driving pulley is located at the output end of the second servo motor, and the second driven pulley is coaxially and rotatably located at the first end of the rotating frame, and is coaxially fixed to the rotating frame. The second synchronous belt surrounds the second driving pulley and the second driven pulley. By using the second servo motor to drive the second driving pulley, and then transmitting power to the second driven pulley through the second driving pulley and the second synchronous belt, power from outside the rotating frame is transmitted to the rotating frame to drive the rotating frame to rotate as a whole, thereby rotating the core wire to achieve the purpose of stranding.

[0019] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] like Figures 1 to 4As shown, the external dual-power rotary traction stranding mechanism 1 of the present invention is suitable for transmitting core wire 200 or wrapping tape. It includes a rotating frame 11, a first guide wheel 12, a second guide wheel 13, a first bevel gear 14, a second bevel gear 15, a gear set 16, a first take-up wheel 17, a first drive mechanism 18, a second drive mechanism 160, and a support 170. Both ends of the rotating frame 11 are mounted on the support 170 via bearings. The first guide wheel 12 is pivotally connected to the first end of the rotating frame 11, with its pivot axis perpendicular to the central axis of the rotating frame 11. The second guide wheel 13 is pivotally connected to the second end of the rotating frame 11, with its pivot axis perpendicular to the central axis of the rotating frame 11 and parallel to the pivot axis of the first guide wheel 12. The first bevel gear 14 is coaxially and rotatably fitted onto the first end of the rotating frame 11. The second bevel gear 15 is pivotally connected to the outside of the rotating frame 11 and meshes with the first bevel gear 14. The central axis of the second bevel gear 15 is perpendicular to the central axis of the first bevel gear 14. The first take-up wheel 17 is pivotally connected to the rotating frame 11, with the pivot axis perpendicular to the central axis of the rotating frame 11 and parallel to the central axis of the first thread guide wheel 12. The input gear of the gear set 16 is coaxially fixed with the second bevel gear 15, and the output gear of the gear set 16 is coaxially fixed with the first take-up wheel 17. The input gear and output gear of the gear set 16 mesh with each other. The first drive mechanism 18 is mounted on the bracket 170 and drives the first bevel gear 14 to rotate; the second drive mechanism 160 is mounted on the bracket 170 and drives the rotating frame 11 to rotate.

[0021] Please see Figure 3 and Figure 4 The rotating frame 11 includes a first rotating shaft 111, a frame 112, and a second rotating shaft 113. The first rotating shaft 111 forms the first end of the rotating frame 11, and the second rotating shaft 113 forms the second end of the rotating frame 11. The first rotating shaft 111 and the second rotating shaft 113 are fixedly connected to both ends of the frame 112, respectively. The frame 112 has a square cross-section, and one side of the frame 112 is provided with a receiving groove 112a communicating with the outside. The first rotating shaft 111 is disposed at one end of the frame 112, and the second rotating shaft 113 is disposed at the other end of the frame 112. By setting the receiving groove 112a, the first take-up wheel 17 can be placed in the receiving groove 112a, which not only facilitates the installation of the first take-up wheel 17, but also allows the core wire 200 to be located in the receiving groove 112a during the conveying process, effectively reducing the wind resistance and noise of the core wire 200 during transmission, reducing the power of the motor, saving energy and protecting the environment, and improving the accuracy of conveying the core wire 200.

[0022] like Figure 3 and Figure 4As shown, the external dual-power rotary traction stranding mechanism 1 further includes a second take-up wheel 19, which is pivotally connected to the rotating frame 11. The pivot axis is perpendicular to the central axis of the rotating frame 11 and parallel to the pivot axis of the first take-up wheel 17. The first take-up wheel 17 and the second take-up wheel 19 are arranged sequentially along the direction from the first end to the second end of the rotating frame 11.

[0023] For example Figure 1 , Figure 3 and Figure 4As shown, the external dual-power rotary traction stranding mechanism 1 further includes a feedback wheel 110, an elastic element 120, and a position sensing device 130. The feedback wheel 110 is rotatably mounted on the rotating frame 11 via a wheel axle 110a, and the wheel axle 110a is slidably mounted within an elongated hole 114 of the rotating frame 11, with the sliding direction along the central axis of the rotating frame 11. The wheel axle 110a is perpendicular to the central axis of the rotating frame 11 and parallel to the pivot axis of the first take-up wheel 17. By slidably mounting the feedback wheel 110 on the rotating frame 11, the traction speed of the core wire 200 can be monitored and a feedback electrical signal can be generated to ensure that the feeding motor delivers the core material at a uniform speed. The elastic element 120 is disposed between the feedback wheel 110 and the wheel axle 110a and is located on the side closer to the second take-up wheel 19. The elastic element 120 is a compression spring, respectively disposed at both ends of the axle 110a; the position sensing device 130 is disposed between the axle 110a and the rotating frame 11 to detect the displacement of the feedback wheel 110. By setting the elastic element 120, and under the conveying action of the core wire 200, the feedback wheel 110 can move back and forth. By setting the position sensing device 130, the position change of the feedback wheel 110 can be automatically monitored to detect the change in the conveying speed of the core wire. That is, the control system can feed back to the take-up or pay-off reel motor outside the mechanism to increase or decrease the output speed, thereby achieving the purpose of automatic control and uniform speed conveying of wire material, so as to improve the stability and accuracy of the core wire 200 conveying. Specifically, the position sensing device 130 includes a displacement sensor 131 and a sensing plate 132. The external dual-power rotary traction stranded wire mechanism 1 also includes a slip ring 140. The sensing plate 132 is disposed on the side wall of the rotating frame 11. The length direction of the sensing plate 132 is arranged along the sliding direction of the feedback wheel 110, and the width of the sensing plate 132 gradually decreases from the first end to the second end of the rotating frame 11. The sensing plate 132 is located on the upper side of the wheel axle 110a. The displacement sensor 131 is disposed on the wheel axle 110a and moves closer to or further away from the sensing plate 132 as the wheel axle 110a moves. Specifically, the closer the wheel axle 110a moves to the first end of the rotating frame 11, the smaller the distance between the displacement sensor 131 and the sensing plate 132, and vice versa. The induction plate 132 generates analog voltages of different magnitudes at different distances from the displacement sensor 131, which can then be fed back to the control system to control the output speed of the take-up or pay-off reel outside the mechanism. The slip ring 140 is coaxially and rotatably mounted on the rotating frame 11 and is electrically connected to both the displacement sensor 131 and the induction plate 132.Since the displacement sensor 131 and the sensing plate 132 are mounted on the rotating frame 11, and the rotating frame 11 rotates around its own central axis, the sensing signal cannot be transmitted in a straight line via a wire. Therefore, the slip ring 140 is provided to output the sensing signal without affecting the rotation of the rotating frame 11, ensuring the continuous operation of the position sensing device 130. Alternatively, the position sensing device of this invention can also be separately mounted on the outside of the stranded wire mechanism and close to the axle, thus eliminating the need for a slip ring and simplifying the structure.

[0024] Please see again Figure 3 and Figure 4 The first take-up wheel 17, the second take-up wheel 19, and the feedback wheel 110 have the same diameter. The first guide wheel 12, the first bevel gear 14, the first take-up wheel 17, the second take-up wheel 19, the feedback wheel 110, and the second guide wheel 13 are arranged sequentially from the first end to the second end of the rotating frame 11. The first rotating shaft 111 has a first through hole 111a communicating with the frame 112, allowing the core wire 200 to enter the frame 112 from the first guide wheel 12. Similarly, the second rotating shaft 113 has a second through hole 113a communicating with the frame 112, allowing the core wire 200 to extend from the feedback wheel 110 to the second guide wheel 13. The first take-up wheel 17 has three independent grooves circumferentially arranged on its rim, the second take-up wheel 19 has five independent grooves circumferentially arranged on its rim, and the feedback wheel 110 has three independent grooves circumferentially arranged on its rim. The specific winding path is as follows: After the core wire 200 passes around the first guide wheel 12, it passes over the first groove of the first take-up wheel 17 from the top, then passes over the first groove of the second take-up wheel 19 from the bottom, and then returns from the first groove on the upper side of the second take-up wheel 19 to the second groove on the lower side of the first take-up wheel 17, and so on, sequentially crossing all the grooves of the first take-up wheel 17; then, the core wire 200 is led out from the groove of the second take-up wheel 19. After that, the core wire 200 continues to wind between the groove of the second take-up wheel 19 and the groove of the feedback wheel 110 from the outside. After passing over all the grooves of the second take-up wheel 19, the core wire 200 is finally led out from the groove on the lower side of the feedback wheel 110 to the second guide wheel 13.

[0025] like Figure 2 and Figure 3As shown, the external dual-power rotary traction stranding mechanism 1 also includes a counterweight 150, which is disposed on the side of the rotating frame 11 opposite to the second bevel gear 15. The central axis of the counterweight 150 is coaxial with the central axis of the second bevel gear 15. Since the second bevel gear 15 and the gear set 16 are disposed on one side of the rotating frame 11, the forces on both sides of the rotating frame 11 will be unbalanced. Therefore, the counterweight 150 can balance the forces on both sides of the rotating frame 11, thereby making the rotation of the rotating frame 11 more stable, reducing vibration, and lowering noise, which is beneficial for the continuous production and processing of the core wire 200.

[0026] like Figure 1 and Figure 3 As shown, the first drive mechanism 18 includes a first servo motor 181, a first driving pulley 182, a first driven pulley 183, and a first synchronous belt 184. The first servo motor 181 is mounted on the bracket 170. The first driving pulley 182 is located at the output end of the first servo motor 181. The first driven pulley 183 is coaxially and rotatably mounted on the first end of the rotating frame 11, and the first driven pulley 183 is coaxially fixed with the first bevel gear 14. The first synchronous belt 184 surrounds the first driving pulley 182 and the first driven pulley 183. By using the first servo motor 181 to drive the first driving pulley 182, and then transmitting power to the first bevel gear 14 through the first driving pulley 182, the first synchronous belt 184, and the first driven pulley 183, power from outside the rotating frame 11 is transmitted to inside the rotating frame 11 to drive the first take-up wheel 17 to rotate, thereby achieving the purpose of actively traction of the core wire 200.

[0027] For example Figure 1 and Figure 3As shown, the second drive mechanism 160 includes a second servo motor 161, a second driving pulley 162, a second driven pulley 163, and a second synchronous belt 164. The second servo motor 161 is mounted on the bracket 170. The second driving pulley 162 is located at the output end of the second servo motor 161. The second driven pulley 163 is coaxially and rotatably mounted on the first end of the rotating frame 11, and is coaxially fixed with the rotating frame 11. The second synchronous belt 164 surrounds the second driving pulley 162 and the second driven pulley 163. By using the second servo motor 161 to drive the second driving pulley 162, and then transmitting power to the second driven pulley 163 through the second driving pulley 162 and the second synchronous belt 164, power from outside the rotating frame 11 is transmitted to the rotating frame 11 to drive the rotating frame 11 to rotate as a whole, thereby rotating the core wire 200 to achieve the purpose of stranding.

[0028] In summary and in combination Figure 3 and Figure 4 The working principle of the external dual-power rotary traction stranding mechanism 1 of the present invention will be described in detail below:

[0029] First, the core wire 200 is sequentially threaded from the end of the first rotating shaft 111 through the first guide roller 12, the first take-up roller 17, the second take-up roller 19, the feedback roller 110, and the second guide roller 13, and then led out from the end of the second rotating shaft 113. Then, the first servo motor 181 and the second servo motor 161 are simultaneously started. The first servo motor 181 drives the first drive pulley 182, which in turn drives the first driven pulley 183 via the first synchronous belt 184. The first driven pulley 183 drives the first bevel gear 14 to rotate, which in turn drives the second bevel gear 15, which in turn drives the gear set 16 to rotate, finally driving the first take-up roller 17 to rotate, actively pulling the core wire 200. Afterwards, the core wire 200 is output after passing through the second take-up roller 19, the feedback roller 110, and the second guide roller 13. At the same time, the second servo motor 161 drives the rotating frame 11 to rotate, and the rotating frame 11 drives the first wire guide wheel 12, the first bevel gear 14, the second bevel gear 15, the gear set 16, the first take-up wheel 17, the second take-up wheel 19, the feedback wheel 110, and the second wire guide wheel 13 to rotate around the central axis of the rotating frame 11, thereby causing the core wire 200 to rotate around the central axis of the rotating frame 11 while being output forward, thus realizing wire stranding.

[0030] Compared with the prior art, the present invention sets up a rotating frame 11, on which a first guide wheel 12, a first take-up wheel 17, and a second guide wheel 13 are sequentially arranged, so that the core wire 200 can sequentially pass around the first guide wheel 12, the first take-up wheel 17, and the second guide wheel 13. Furthermore, a first bevel gear 14 is coaxially fitted onto the rotating frame 11, and a first drive mechanism 18 drives the first bevel gear 14 to rotate. A second bevel gear 15 and a gear set 16 transmit the power of the first bevel gear 14 to the first take-up wheel 17, thereby allowing the first take-up wheel 17 to actively pull the core wire 200 forward. Simultaneously, by using a second drive mechanism 160 to drive the rotating frame 11, the entire rotating frame 11 can rotate around a central axis, thus allowing the core wire 200 to be twisted while being output forward. Therefore, the present invention can use an external power to pull the core wire 200 to output, and at the same time use another external power to drive the core wire 200 to rotate, thereby making the core wire 200 move in a 90-degree space. Its structure is simple, small in size and very convenient to control.

[0031] The stranding mechanism of the present invention is not limited to use on rotary traction stranding machines, but can also be used on untwisting and pay-off machines to achieve reversible operation. Specifically, the pay-off mechanism of the untwisting and pay-off machine is connected to the end of the stranding mechanism of the present invention near the feedback wheel 110, and the travel direction of the core wire 200 is transmitted from the second guide wheel 13 end to the first guide wheel 12 end. At this time, the first servo motor 181 changes from the power mode used to drive the first take-up wheel 17 to rotate in the above embodiment to a torque mode, that is, it provides a constant tension to the first take-up wheel 17 opposite to the travel direction of the core wire 200. Moreover, after the position sensing device 130 detects the displacement of the feedback wheel 110, it controls the pay-off motor of the pay-off mechanism to adjust the output speed through the control system, thereby controlling the pay-off amount and ensuring the stability of untwisting and pay-off.

[0032] Furthermore, the structure of the present invention is not limited to the core wire 200; it is also applicable to the conveyor tape. It is only necessary to adjust the shape of the first guide roller 12, the second guide roller 13, the first take-up roller 17, the second take-up roller 19, and the feedback roller 110 to make them suitable for the tape. It is not limited to the core wire alone; any other continuous strip material similar to the core wire is within the scope of protection of this application.

[0033] Furthermore, the position sensing device 130 of the present invention is not limited to using the displacement sensor 131; other electrical components and detection feedback mechanical structures capable of converting displacement into voltage signals may also be used, all of which are within the scope of protection of this application. The driving mechanisms of the present invention are not limited to using servo motors; ordinary motors may also be used, all of which are within the scope of protection of this application.

[0034] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
