A take-up device for a stranding machine

Abstract

This utility model discloses a take-up device for a stranding machine. The take-up device employs a buffer mechanism, positioned between the take-up mechanism and the stranding device. Guide rollers are located below both the take-up and stranding devices to prevent the cable from becoming uneven between them, thus providing a buffer length of cable. The buffer mechanism allows for real-time adjustment of cable tension, preventing cable breakage due to excessive tension or cable tangling and accumulation due to insufficient tension, thereby improving cable production quality. The buffer mechanism can also be used for power failure protection. If the stranding device experiences a sudden power outage or other factors prevent cable stranding and delivery, the buffer mechanism can trigger power failure protection before the cable is straightened, stopping the take-up mechanism and preventing cable breakage or equipment damage, thus improving production safety.

Description

Technical Field

[0001] This utility model relates to the technology of winding copper, aluminum and other metal cables after they have been twisted by a stranding mechanism, and particularly to a winding device for a stranding machine. Background Technology

[0002] A stranding machine is a winding device used to produce wires, cables, and other cables by twisting multiple strands together to form a single cable. The stranding principle of a stranding machine is as follows: multiple strands of wire are released by the unwinding device, and these strands enter the stranding bow through the main shaft. The rotating bow twists the multiple strands together, and finally, the stranded wire is wound into the take-up device by the guide roller.

[0003] In existing cable winding technology, when the stranding device of the stranding machine stops stranding and transmitting the cable due to malfunction or other factors, the winding device continues to operate and pull the cable to wind up, which can easily lead to cable breakage or damage to production equipment. In such emergencies, relying on workers to stop the winding device is delayed, and workers may not be nearby or able to detect the emergency and stop the winding device in time, which is not conducive to safe production.

[0004] In addition, when the stranding and take-up devices of the instant stranding machine are operating normally, after stranding and take-up are completed, the rollers of the take-up device are wrapped with a large amount of cable and have a large inertia. Even if the take-up device has been de-energized, the rollers will continue to rotate due to inertia, which can easily pull the cable and cause the cable to break due to excessive tension, which is not conducive to high-quality production.

[0015] In an optional embodiment, the connecting plate is provided with a sliding groove, and the sleeve is slidably connected to the sliding groove via a slider.

[0016] In an optional embodiment, the take-up device of a stranding machine further includes a drive mechanism, the drive mechanism including a first drive member, a screw and a nut, the first drive member being mounted on a first support plate, one end of the screw being connected to the output shaft of the first drive member, the other end of the screw being rotatably connected to a second support plate, the nut being rotatably connected to the screw, the nut being connected to the sleeve, and the first drive member being electrically connected to the control system.

[0017] In an optional embodiment, a second sensor and a third sensor are respectively provided at both ends of the slide groove.

[0019] In an optional embodiment, the take-up mechanism includes a second drive member and a roller. The second drive member is mounted on the first support plate. One end of the roller is connected to the output shaft of the second drive member, and the other end of the roller is rotatably connected to the second support plate. The second drive member is electrically connected to the control system.

[0020] In an optional embodiment, the take-up mechanism further includes a second bearing, a connecting shaft, a second coupling, and a third coupling. The second bearing is mounted on the second support plate, the connecting shaft is mounted on the second bearing, the second coupling connects to the connecting shaft, and the third coupling connects to the output shaft of the second drive member.

[0022] In an alternative embodiment, the elastic element is a spring.

[0023] Compared with the prior art, the present invention has the following technical effects:

[0024] 1. The take-up device of the stranding machine of this utility model adopts a buffer mechanism. The buffer mechanism is set between the take-up mechanism and the stranding device. The guide wheel is located below the take-up mechanism and the stranding device, so that the cable is not straight between the take-up mechanism and the stranding device, thereby reserving a buffer length of cable.

[0025] The buffer mechanism can adjust the cable tension in real time, preventing the cable from breaking due to excessive tension or becoming messy and clumped due to insufficient tension, thus improving the quality of cable production.

[0026] The buffer mechanism can also be used for power failure protection. When the stranding device suddenly loses power or other factors stop stranding and transmitting the cable, the buffer mechanism can trigger the power failure protection before the cable is pulled straight, stopping the take-up mechanism from continuing to take up the cable, thus preventing the cable from being pulled apart or the production equipment from being damaged, and improving production safety.

[0027] 2. The take-up device of the stranding machine of this utility model adopts a drive mechanism. During the take-up process, the drive buffer mechanism drives the cable to move back and forth, so that the cable is evenly wound on the take-up mechanism and avoids the cable from being concentrated and tangled.

[0028] 3. The buffer mechanism also adopts a friction layer. Before the sliding rod of the cable-driven buffer mechanism triggers the power-off protection, the sliding rod first slides and rubs against the friction layer to offset part of the cable tension. This avoids the sliding rod accidentally touching the first sensor and triggering the power-off protection during the normal real-time tension adjustment process of the buffer mechanism, thus improving production safety.

[0039] Reference Figures 1-3 This utility model proposes a take-up device 100 for a stranding machine.

[0040] In this embodiment of the utility model, the take-up device of the stranding machine includes a first support plate 1, a second support plate 2, a take-up mechanism 3, a drive mechanism 4, a connecting plate 5, a buffer mechanism 6, and a control system. The take-up mechanism 3 is mounted on the first support plate 1 and the second support plate 2; the drive mechanism 4 is mounted on the first support plate 1 and the second support plate 2; the connecting plate 5 connects the first support plate 1 and the second support plate 2; the buffer mechanism 6 includes a sleeve 61, a sliding rod 62, an elastic element 63, a guide wheel 64, and a first sensor 65. The sleeve 61 is slidably mounted on the connecting plate 5 and connected to the drive mechanism 4. One end of the sliding rod 62 is slidably sleeved inside the sleeve 61, and the guide wheel 64 is rotatably mounted on the other end of the sliding rod 62. The elastic element 63 is disposed inside the sleeve 61 and its two ends abut against the sleeve 61 and the sliding rod 62 respectively. In the radial direction of the sleeve 61, the sleeve 61 has a mounting hole 66 communicating with the inner and outer sides of the sleeve 61. The first sensor 65 is mounted on the mounting hole 66 and is used to sense the position of the sliding rod 62. The control system is electrically connected to the drive mechanism 4, the take-up mechanism 3, and the first sensor 65.

[0041] The buffer mechanism 6 is disposed between the take-up mechanism 3 and the stranding device 200. In the direction from the sleeve 61 to the guide wheel 64, the guide wheel 64 is located below the take-up mechanism 3 and the stranding device 200. The drive mechanism 4 can drive the buffer mechanism 6 to slide between the first support plate 1 and the second support plate 2. The sliding rod 62 can slide relative to the sleeve 61 under the drive of the cable 300. The cable can be a copper cable, an aluminum cable, or a copper-clad aluminum cable.

[0042] Specifically, the connecting plate 5 is fixedly connected to the first support plate 1 and the second support plate 2 by several screws, so that the first support plate 1 and the second support plate 2 can support the take-up mechanism 3, the drive mechanism 4, and the buffer mechanism 6, thereby enhancing the stability of the take-up device 100 of a stranding machine. The elastic element 63 is a spring, which is used to resist the sliding rod 62 from sliding towards the sleeve 61 and to return the sliding rod 62 to its original position away from the sleeve 61, so as to ensure that the cable 300 has sufficient tension when taking up the cable and to avoid the cable 300 becoming messy and piled up due to insufficient tension.

[0043] The buffer mechanism 6 is located between the take-up mechanism 3 and the stranding device 200. After the cable 300 is stranded by the stranding device 200, it is conveyed to the guide wheel 64 of the buffer mechanism 6 and guided by the guide wheel 64 to the take-up mechanism 3 for winding and collection. The buffer mechanism 6 can be used to adjust the tension of the cable 300 in real time. During the process of the stranding device 200 stranding and conveying the cable 300 and the take-up mechanism 3 winding the cable 300, the tension of the cable 300 will change due to changes in the speed of the stranding device 200 and the take-up mechanism 3. If the tension change is too large, it will cause the cable 300 to break or become messy and piled up, which is not conducive to high-quality production. When the tension of the cable 300 is too large, the cable 300 can drive the guide wheel 64 to drive the sliding rod 62 to slide towards the sleeve 61, thereby converting the potential energy of the cable 300 caused by excessive tension into the kinetic energy of the guide wheel 64 and the sliding rod 62 and the potential energy of the elastic element 63, thereby reducing the tension of the cable 300 and preventing the cable 300 from breaking due to excessive tension. When the tension of the cable 300 is too low, the gravity of the guide wheel 64 and the sliding rod 62, as well as the potential energy of the elastic element 63, can cause the sliding rod 62 to slide away from the sleeve 61, converting the kinetic energy of the guide wheel 64 and the sliding rod 62, as well as the potential energy of the elastic element 63, into the potential energy of the cable 300, thereby increasing the tension of the cable 300 and preventing the cable 300 from becoming messy and piling up due to insufficient tension.

[0044] The buffer mechanism 6 can also be used for power failure protection. When the stranding device 200 stops stranding and conveying the cable 300 due to a malfunction or other factors, but the take-up mechanism 3 continues to operate and pull the cable 300 to take it back, it is very easy for the cable 300 to break or damage the production equipment. In such an emergency, relying on the worker to stop the take-up mechanism 3 to take it back is delayed, and the worker may not be nearby or may not be able to detect the emergency and stop the take-up mechanism 3 to take it back in time. The buffer mechanism 6 can trigger power failure protection when the take-up mechanism 3 pulls the cable 300 and drives the sliding rod 62 to slide a set distance towards the sleeve 61. Specifically, the buffer mechanism 6 is set between the take-up mechanism 3 and the stranding device 200, in the direction from the sleeve 61 to the guide wheel 64. The guide wheel 64 is located below the take-up mechanism 3 and the stranding device 200, so that the cable 300 is not straight between the take-up mechanism 3 and the stranding device 200, thereby reserving a buffer length of cable 300.

[0045] When the stranding device 200 suddenly loses power or other factors stop stranding and transmitting the cable 300, the take-up mechanism 3 continues to take up the cable, gradually straightening it. This pulls the cable 300, driving the sliding rod 62 to slide a set distance towards the sleeve 61. Before the cable 300 is fully straightened, the sliding rod 62 reaches the first sensor 65, triggering the sensor to send a signal to the control system. The control system then sends a control signal to stop the take-up mechanism 3 from taking up the cable before it is fully straightened, preventing the cable 300 from breaking. After adjusting the take-up mechanism 3 and the stranding device 200, the sliding rod 62 slides away from the sleeve 61 and away from the first sensor 65. The first sensor 65 then sends a signal to the control system, which in turn sends a control signal to control the take-up mechanism 3 to continue taking up the cable. The first sensor 65 can be a limit switch or an infrared sensor, but is not limited to these.

[0046] The drive mechanism 4 drives the sleeve 61 to slide back and forth between the first support plate 1 and the second support plate 2, thereby driving the sliding rod 62, guide wheel 64, and cable 300 to move back and forth between the first support plate 1 and the second support plate 2. This, in conjunction with the take-up mechanism 3, evenly winds the twisted cable 300 onto the take-up mechanism 3, preventing the cable 300 from being concentrated in one place and causing uneven winding. It is understood that when the first sensor 65 sends a signal to the control system, and the control system sends a control signal to stop or resume winding of the take-up mechanism 3, the control system also sends a control signal to stop or resume the drive mechanism 4 to drive the sleeve 61 to move back and forth between the first support plate 1 and the second support plate 2.

[0047] In one embodiment of this utility model, a friction layer 67 is further provided on the inner side of the sleeve 61, and the mounting hole 66 penetrates the friction layer 67. During the sliding process of the sliding rod 62 relative to the sleeve 61, the friction layer 67 can contact the sliding rod 62. During the sliding process of the sliding rod 62 towards the sleeve 61, the sliding rod 62 first contacts the friction layer 67, slides a short distance on the friction layer 67, and then slides to the first sensor 65. This prevents the sleeve 61 from accidentally touching the first sensor 65 and causing the winding mechanism 3 and the drive mechanism 4 to stop operating when the stranding device 200 and the take-up mechanism 3 are operating normally and the buffer mechanism 6 is adjusting the tension of the cable 300 in real time. Furthermore, the friction layer 67 provided on the inner side of the sleeve 61 increases the friction force on the sliding rod 62 when it slides towards the sleeve 61, preventing the cable 300 from being quickly straightened and further improving the safety of the buffer mechanism 6.

[0048] In one embodiment of this utility model, the drive mechanism 4 includes a first drive member 41, a screw 42, a nut 43, a first bearing 44, and a first coupling 45. The first drive member 41 is mounted on a first support plate 1. One end of the screw 42 is connected to the output shaft of the first drive member 41, and the other end of the screw 42 is rotatably connected to a second support plate 2. The nut 43 is rotatably connected to the screw 42 and is connected to a sleeve 61. The first drive member 41 is electrically connected to the control system. The first bearing 44 is mounted on the second support plate 2, and the screw 42 is rotatably connected to the second support plate 2 via the first bearing 44. The screw 42 is connected to the output shaft of the first drive member 41 via the first coupling 45.

[0049] A groove 51 is provided on the connecting plate 5. The sleeve 61 is slidably connected to the groove 51 via a slider 52. A second sensor 53 and a third sensor 54 are respectively provided at both ends of the groove 51. The second sensor 53 and the third sensor 54 are used to sense the position of the sleeve 61. The second sensor 53 and the third sensor 54 are electrically connected to the control system. The second sensor 53 and the third sensor 54 can be limit switches or infrared sensors, but are not limited to these.

[0050] The first driving component 41 can be a motor or electric motor. The rotation of the output shaft of the first driving component 41 drives the screw 42 to rotate, causing the nut 43 to drive the buffer mechanism 6 to slide relative to the connecting plate 5 between the first support plate 1 and the second support plate 2. The first driving component 41 is controlled to rotate forward or in a directional manner by the second sensor 53, the third sensor 54, and the control system, thereby controlling the reciprocating sliding of the buffer mechanism 6 relative to the connecting plate 5 between the first support plate 1 and the second support plate 2. The control of the first driving component 41 to rotate forward or in a directional manner by the second sensor 53, the third sensor 54, and the control system is a common electrical technology and will not be described in detail here.

[0051] The buffer mechanism 6 can be removed from the take-up device of the stranding machine by disassembling the first bearing 44, the first coupling 45 and the connecting plate 5, and the installation is the same.

[0052] In one embodiment of this utility model, the take-up mechanism 3 includes a second drive member 31 and a roller 32. The second drive member 31 is mounted on the first support plate 1. One end of the roller 32 is connected to the output shaft of the second drive member 31, and the other end of the roller 32 is rotatably connected to the second support plate 2. The second drive member 31 is electrically connected to the control system. The second drive member 31 can be a motor or an electric motor, but is not limited thereto.

[0053] In one embodiment of this utility model, the take-up mechanism 3 further includes a second bearing 33, a connecting shaft 34, a second coupling 35, and a third coupling 36. The second bearing 33 is mounted on the second support plate 2, the connecting shaft 34 is mounted on the second bearing 33, the second coupling 35 is connected to the connecting shaft 34, the third coupling 36 is connected to the output shaft of the second drive member 31, and the two ends of the rotating shaft 321 of the roller 32 are respectively connected to the second coupling 35 and the third coupling 36.

[0054] The roller 32 can be removed from the take-up device of the stranding machine by disassembling the second coupling 35 and the third coupling 36. The installation is done in the same way to avoid frequent replacement of the second bearing 33.

[0055] In a specific application of this utility model, after the cable 300 is twisted in the stranding device 200, it is conveyed to the buffer mechanism 6 and then guided by the guide wheel 64 of the buffer mechanism 6 to the roller 32. The output shaft of the second drive member 31 rotates, driving the roller 32 to rotate and winding the cable 300 around it. At the same time, the output shaft of the first drive member 41 rotates, driving the screw 42 to rotate. With the cooperation of the second sensor 53, the third sensor 54, and the control system, the nut 43 drives the buffer mechanism 6 to slide back and forth between the connecting plate 5 and the first support plate 1 and the second support plate 2, so that the cable 300 is evenly wound around the roller 32.

[0056] The buffer mechanism 6 can be used to adjust the tension of the cable 300 in real time. During the twisting and conveying of the cable 300 by the stranding device 200 and the winding of the cable 300 by the take-up mechanism 3, the tension of the cable 300 will change due to the speed changes of the stranding device 200 and the take-up mechanism 3. If the tension change is too large, it will cause the cable 300 to break or become messy and piled up, which is not conducive to high-quality production. When the tension of the cable 300 is too large, the cable 300 can drive the guide wheel 64 to drive the sliding rod 62 to slide towards the sleeve 61, thereby converting the potential energy generated by the excessive tension of the cable 300 into the kinetic energy of the guide wheel 64 and the sliding rod 62 and the potential energy of the elastic element 63, thereby reducing the tension of the cable 300 and preventing the cable 300 from breaking due to excessive tension. When the tension of the cable 300 is too low, the gravity of the guide wheel 64 and the sliding rod 62, as well as the potential energy of the elastic element 63, can cause the sliding rod 62 to slide away from the sleeve 61, converting the kinetic energy of the guide wheel 64 and the sliding rod 62, as well as the potential energy of the elastic element 63, into the potential energy of the cable 300, thereby increasing the tension of the cable 300 and preventing the cable 300 from becoming messy and piling up due to insufficient tension.

[0057] The buffer mechanism 6 can also be used for power failure protection. When the stranding device 200 stops stranding and conveying the cable 300 due to a malfunction or other factors, but the take-up mechanism 3 continues to operate and pull the cable 300 to take it back, it is very easy for the cable 300 to break or damage the production equipment. In such an emergency, relying on the worker to stop the take-up mechanism 3 to take it back is delayed, and the worker may not be nearby or may not be able to detect the emergency and stop the take-up mechanism 3 to take it back in time. The buffer mechanism 6 can trigger power failure protection when the take-up mechanism 3 pulls the cable 300 and drives the sliding rod 62 to slide a set distance towards the sleeve 61. Specifically, the buffer mechanism 6 is set between the take-up mechanism 3 and the stranding device 200, in the direction from the sleeve 61 to the guide wheel 64. The guide wheel 64 is located below the take-up mechanism 3 and the stranding device 200, so that the cable 300 is not straight between the take-up mechanism 3 and the stranding device 200, thereby reserving a buffer length of cable 300.

[0058] When the stranding device 200 suddenly loses power or other factors stop stranding and transmitting the cable 300, the take-up mechanism 3 continues to take up the cable, gradually straightening it. This pulls the cable 300, driving the sliding rod 62 to slide a set distance towards the sleeve 61. Before the cable 300 is fully straightened, the sliding rod 62 reaches the first sensor 65, triggering the sensor to send a signal to the control system. The control system then sends a control signal to stop the take-up mechanism 3 from taking up the cable before it is fully straightened, preventing the cable 300 from breaking. After adjusting the take-up mechanism 3 and the stranding device 200, the sliding rod 62 slides away from the sleeve 61 and away from the first sensor 65. The first sensor 65 then sends a signal to the control system, which in turn sends a control signal to control the take-up mechanism 3 to continue taking up the cable. The first sensor 65 can be a limit switch or an infrared sensor, but is not limited to these.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
