Description

Technical Field

[0001] This invention belongs to the field of cable recycling technology, and more specifically, relates to a cable recycling device. Background Technology

[0002] Cables consist of one or more inner conductors, a shielding layer, a load-bearing layer, and an outer sheath. They share common characteristics such as small diameter, large length, and high flexibility, and are widely used in power systems, information transmission, instrumentation systems, medical applications, and fire protection.

[0003] During the production and laying of cables, cables need to be continuously retrieved onto a winch, forming a ring shape before being removed to ensure neat arrangement and transportation of the cables.

[0004] However, during cable recycling, the winch is driven by a motor. When recycling is complete, it is often difficult for the motor to be stopped in time, causing the cable to be over-recycled. As a result, the cable end spins freely on the winch and becomes loose, leading to cable recycling failure. Summary of the Invention

[0005] In view of the above-mentioned defects or improvement needs of the prior art, the present invention provides a cable recycling device, the purpose of which is to automatically control the motor to stop when the cable is recycled to the correct position, thereby effectively avoiding the problem of cable recycling failure due to over-recycling.

[0006] The present invention provides a cable recycling device, the recycling device comprising a recycling component and a control component;

[0007] The recycling assembly includes a winch, a motor, and a cable channel. The output end of the motor is connected to the winch to drive the winch to rotate. The cable channel has a through groove for conducting cables and is arranged opposite to the winch.

[0008] The control assembly includes a rotating rod, a roller, a magnetic sensor, and a controller. One end of the rotating rod is rotatably arranged at the top of the cable channel, and the roller is rotatably arranged at the other end of the rotating rod, with a magnet at the other end. The magnetic sensor is located on one side of the roller to sense the position of the magnet. The controller is electrically connected to the magnetic sensor and the motor, respectively.

[0009] The roller is configured such that, in a first state, the edge of the roller rolls in contact with the outer edge of the cable, and the magnet and the magnetic sensor are misaligned; in a second state, the roller is separated from the cable, and the magnet and the magnetic sensor are aligned, and the controller controls the motor to stop.

[0010] Optionally, the other end of the rotating rod has a rotating shaft, the rotating shaft being perpendicular to the through groove, and a bearing is provided inside the roller, the bearing being sleeved on the rotating shaft.

[0011] Optionally, the control assembly further includes a reset spring, with its two ends connected to one end of the rotating rod and the top of the cable channel, respectively, and the reset spring extending along the direction of the through groove.

[0012] Optionally, the top of the cable channel has a support base, and one end of the reset spring is mounted on the support base.

[0013] Optionally, there are two rotating rods, which are arranged at intervals, and the two ends of the rotating shaft are respectively inserted into the other ends of the two rotating rods.

[0014] Optionally, the recycling assembly further includes two rotatable compression rollers, which are spaced apart to clamp the cable.

[0015] Optionally, the rotating rod is an L-shaped rod.

[0016] Optionally, the number of control components is two.

[0017] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0018] In the cable recycling device provided in this embodiment of the invention, during cable recycling, firstly, after the cable passes through the cable channel, one end is fixed to the winch. Then, the motor drives the winch to rotate, causing the cable to be gradually recycled onto the winch. At this time, the roller is in the first state, with the edge of the roller rolling in contact with the outer edge of the cable, and the magnet and magnetic sensor are misaligned. The magnetic sensor cannot sense the magnetic field provided by the magnet and will not transmit an electrical signal to the controller, while the motor continues to operate. When the cable recycling is complete, the other end of the cable separates from the roller. At this time, the roller rotates under the action of gravity, thereby driving the rotating rod to rotate, so that the magnet and the magnetic sensor are aligned (at this time, the roller switches to the second state). The magnetic sensor senses the magnetic field provided by the magnet and transmits an electrical signal to the controller, which then promptly controls the motor to automatically stop, thereby effectively avoiding the problem of cable recycling failure due to over-recycling. Finally, the other end of the cable is fixed to the recycled cable and removed.

[0019] In other words, the cable recycling device provided by this invention can automatically control the motor to stop when the cable is recycled to the correct position, thereby effectively avoiding the problem of cable recycling failure due to over-recycling. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Figure 1 This is a schematic diagram of a cable recycling device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the recycling device includes a recycling component 1 and a control component 2.

[0031] The recycling assembly 1 includes a winch 11, a motor 12, and a cable channel 13. The output end of the motor 12 is connected to the winch 11 to drive the winch 11 to rotate. The cable channel 13 has a through groove 131 for conducting the cable 100. The cable channel 13 is arranged opposite to the winch 11.

[0032] Figure 2 This is a front view of the control component provided in an embodiment of the present invention. Figure 3 This is a side view of the control component provided in an embodiment of the present invention, in conjunction with... Figure 2 and Figure 3 As shown, the control assembly 2 includes a rotating rod 21, a roller 22, a magnetic sensor 23, and a controller (not shown). One end of the rotating rod 21 is rotatably arranged on the top of the cable channel 13, and the roller 22 is rotatably arranged on the other end of the rotating rod 21. The other end of the rotating rod 21 has a magnet 24. The magnetic sensor 23 is located on one side of the roller 22 to sense the position of the magnet 24. The controller is electrically connected to the magnetic sensor 23 and the motor 12 respectively.

[0033] The roller 22 is configured such that when the roller 22 is in the first state, the edge of the roller 22 rolls with the outer edge of the cable 100, and the magnet 24 and the magnetic sensor 23 are misaligned; when the roller 22 is in the second state, the roller 22 is separated from the cable 100, and the magnet 24 and the magnetic sensor 23 are facing each other, and the controller controls the motor 12 to stop.

[0034] In the cable recycling device provided in this embodiment of the invention, when recycling cable 100, firstly, after cable 100 passes through cable channel 13, one end of cable 100 is fixed to winch 11. Then, motor 12 drives winch 11 to rotate, so that cable 100 is gradually recycled onto winch 11. At this time, roller 22 is in the first state (see...). Figure 4 and Figure 5 The edge of roller 22 rolls against the outer edge of cable 100, and magnet 24 and magnetic sensor 23 are misaligned. Magnetic sensor 23 cannot sense the magnetic field provided by magnet 24 and will not transmit an electrical signal to the controller; motor 12 continues to operate. When cable 100 is fully retracted, the other end of cable 100 separates from roller 22. At this time, roller 22 rotates under gravity, thereby driving rotating rod 21 to rotate, so that magnet 24 and magnetic sensor 23 are aligned (at this time, roller 22 switches to the second state, see...). Figure 6 and Figure 7 The magnetic sensor 23 senses the magnetic field provided by the magnet 24 and transmits an electrical signal to the controller. The controller then promptly controls the motor 12 to automatically stop, effectively preventing the cable 100 from being over-retracted and causing the cable 100 to fail to be retrieved. Finally, the other end of the cable 100 is fixed to the retrieved cable 100 and removed.

[0035] In other words, the cable recycling device provided by the present invention can automatically control the motor 12 to stop when the cable 100 is recycled to the correct position, thereby effectively avoiding the problem of cable 100 recycling failure due to over-recycling.

[0036] See you again Figure 2 and Figure 3 The other end of the rotating rod 21 has a rotating shaft 211, which is perpendicular to the through groove 131. A bearing is installed inside the roller 22 and is sleeved on the rotating shaft 211.

[0037] In the above embodiment, the cooperation between the rotating shaft 211 and the bearing not only facilitates the installation of the roller 22 on the rotating rod 21, but also reduces the friction force experienced by the roller 22 during rotation.

[0038] Specifically, the control component 2 also includes a reset spring 25, with its two ends connected to one end of the rotating rod 21 and the top of the cable channel 13, respectively, and the reset spring 25 extending along the direction of the through groove 131.

[0039] It is easy to understand that when the reset spring 25 is not under force, the reset spring 25 and the rotating rod 21 are in a horizontal state. When the cable 100 is in the through groove 131, the cable 100 will lift the roller 22 and the rotating rod 21, at which point the reset spring 25 bends. When the cable 100 is retracted, the cable 100 separates from the roller 22, and the elastic force of the reset spring 25 will pull the rotating rod 21 to quickly return to its original position, thereby ensuring that the roller 22 quickly switches from the first state to the second state, so that the motor 12 can quickly stop.

[0040] For example, the top of the cable channel 13 has a support base 132, and one end of the reset spring 25 is mounted on the support base 132. The support base 132 supports the installation of the reset spring 25 on the cable channel 13.

[0041] For example, there are two rotating rods 21, which are arranged at intervals. The two ends of the rotating shaft 211 are respectively inserted into the other ends of the two rotating rods 21, thereby ensuring that the arrangement of the rotating rods 21 and the rotating shaft 211 is more stable, and making the rotation of the roller 22 more smooth.

[0042] For example, the rotating rod 21 is an L-shaped rod, thereby avoiding interference from the cable channel 13 during the rotation of the rotating rod 21.

[0043] See you again Figure 1 The recycling assembly 1 also includes two rotatable extrusion rollers 14, which are spaced apart to clamp the cable 100.

[0044] In the above embodiment, the extrusion wheel 14 is driven to rotate by an external device, which can not only drive the cable 100 to move and be recycled, but also play a guiding role in the recycling process of the cable 100.

[0045] In this embodiment, there can be two control components 2, thus implementing a redundant design and providing backup for each other, thereby improving the accuracy and reliability of detecting the cable 100 being retrieved into place. That is, when at least one controller receives a sensing signal from the corresponding magnetic sensor 23, it can control the motor 12 to stop, ensuring that if one control component 2 fails, the other control component 2 can still guarantee the reliability of cable 100 retrieval.

[0046] The working principle of this invention is as follows:

[0047] When the retrieval device is working, the cable 100 can move within the cable channel 13. When the cable 100 is retracted, it passes under the roller 22, which is lifted by the cable 100. At this time, the reset spring 25 deforms, and the roller 22 rotates with the cable 100 due to friction. The magnet 24 and the magnetic sensor 23 become misaligned, and no magnetic field signal is detected. The cable 100 can then be retracted within the cable channel 13. When the cable 100 is fully retracted, the roller 22 moves downwards under gravity, the reset spring 25 automatically returns to its original position, and the center of the magnet 24 aligns with the sensing center of the magnetic sensor 23, allowing it to detect a magnetic field signal. The magnetic sensor 23 transmits the signal to the controller, which then stops the motor 12 from retracting. The cable 100 remains in the cable channel 13, preventing over-retraction and potential malfunctions.

[0048] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
