When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0043] With the expansion of the cable production scale in China, it is more and more important to improve the collection efficiency and quality of the cable. At present, after the cable is processed, it is usually wound on a winding drum, so as to facilitate the storage and transportation of the cable, and avoid damage of the cable caused by loose winding. However, the current winding method of the cable usually adopts manual operation of a rotating mechanism for direct winding, and the cable is randomly wound on the winding drum, layer by layer, which leads to difficulty in take-up and pay-out of the cable during use. At the same time, due to the long length, large density and strong toughness of the cable, the take-up and pay-out of the cable is slow during use, and the cable is easily damaged due to loose winding.

[0044] Based on the above ideas and problems, the present application provides a take-up and pay-out device 100. It can be understood that the take-up and pay-out device 100 is arranged to take up and pay out the electric wire and cable, so as to realize winding of the electric wire and cable, facilitate storage and transportation of the electric wire and cable, and avoid damage of the electric wire and cable caused by loose winding.

[0045] In the embodiment, the wire or cable that is wound or unwound by the winding and unwinding device 100 can be the magnetic cable 10; alternatively, at least part of the wire or cable is the magnetic cable 10, which is not limited herein. It can be understood that the winding and unwinding device 100 can accommodate the magnetic cable 10 on the magnetic structure 20 by arranging the magnetic structure 20 and the magnetic cable 10, so that the magnetic cable 10 is orderly wound when being wound or unwound. By arranging the control device 30, the control device 30 is connected with the magnetic structure 20, the magnetic field of the magnetic structure 20 is weakened to reduce the unwinding resistance when unwinding, and the magnetic field of the magnetic structure 20 is strengthened to make the magnetic cable 10 quickly and closely wound on the magnetic structure 20 when winding, thereby facilitating winding and unwinding.

[0046] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the accompanying drawings.

[0047] Please refer to FIGS. 1 to 7, in the embodiment, the winding and unwinding device 100 includes the magnetic structure 20, the control device 30 and the magnetic cable 10, the control device 30 is connected with the magnetic structure 20 and is arranged to adjust the magnetic field strength of the magnetic structure 20, and the magnetic cable 10 can be adsorbed on the magnetic structure 20; wherein when the winding and unwinding device 100 is unwound, the control device 30 weakens the magnetic field of the magnetic structure 20, so that the magnetic cable 10 is separated from the magnetic structure 20 to be unwound; when the winding and unwinding device 100 is wound, the control device 30 strengthens the magnetic field of the magnetic structure 20, so that the magnetic cable 10 is adsorbed on the magnetic structure 20 to be wound.

[0048] In the embodiment, the magnetic structure 20 can be a structure or device with magnetism, for example, the magnetic structure 20 can be made of a magnet or a material with magnetism. It can be understood that the magnetic structure 20 can be an electromagnetic structure or a permanent magnet structure, which is not limited herein.

[0049] Alternatively, the magnetic structure 20 is a magnetic plate 21 or a magnetic core 22 structure. It should be noted that when the magnetic structure 20 is the magnetic plate 21, the magnetic plate 21 can be a plate-shaped structure. The magnetic plate 21 can be entirely made of a magnet. Of course, the magnetic plate 21 can also include a support plate and a magnetic layer structure arranged on the surface of the support plate, which is not limited herein. When the magnetic structure 20 is the magnetic core 22, the magnetic core 22 can be a columnar structure, for example, a cylindrical structure, an elliptical columnar structure or a polygonal columnar structure, which is not limited herein. The magnetic core 22 can be entirely made of a magnet. Of course, the magnetic core 22 can also include a support column and a magnetic layer structure arranged on the surface of the support column, which is not limited herein.

[0050] In the embodiment, the magnetic structure 20 has a magnetic adsorption surface. Optionally, when the magnetic cable 10 is adsorbed to the magnetic structure 20, the magnetism of the part of the magnetic cable 10 in contact with the magnetic adsorption surface of the magnetic structure 20 is opposite to the magnetism of the magnetic adsorption surface of the magnetic structure 20, so that the bottom surface of the magnetic cable 10 can be closely attached to the magnetic adsorption surface of the magnetic structure 20 when the take-up and pay-off device 100 is paying out the cable.

[0051] It can be understood that, during the take-up and pay-out of the magnetic cable 10, for example, when the take-up and pay-out device 100 is paying out the cable, the control device 30 can weaken the magnetism of the magnetic adsorption surface of the magnetic structure 20 to reduce the magnetic force between the magnetic structure 20 and the magnetic cable 10, thereby accelerating the pay-out of the cable. When the take-up and pay-out device 100 is taking up the cable, the control device 30 can strengthen the magnetism of the magnetic adsorption surface of the magnetic structure 20 to strengthen the magnetic force between the magnetic structure 20 and the surface of the magnetic cable 10, so that the magnetic cable 10 is closely attached to the magnetic structure 20, thereby accelerating the take-up of the cable. In this way, the take-up and pay-out speed can be accelerated by controlling the strength of the magnetism of the magnetic structure 20, and automatic take-up and pay-out can be achieved.

[0052] In the embodiment, the control device 30 can be an electromagnetic control structure or a mechanical control structure. For example, when the control device 30 is an electromagnetic control structure, the strength of the magnetic field of the magnetic structure 20 can be adjusted by controlling the current. When the control device 30 is a mechanical control structure, the control device 30 can be a mechanical isolation structure, which covers or blocks the magnetic structure 20 to adjust the strength of the magnetic field of the magnetic structure 20. It can be understood that the control device 30 can be selected and adjusted according to the actual application scenario, as long as it is a structure that can adjust the strength of the magnetic field of the magnetic structure 20. For reference, the prior art is not limited herein.

[0053] The take-up and pay-out device 100 of the present application is provided with the magnetic structure 20 and the magnetic cable 10, and the magnetic structure 20 is connected to the control device 30 to adjust the strength of the magnetic field of the magnetic structure 20 by the control device 30, so that the magnetic cable 10 can be movably adsorbed to the magnetic structure 20. In this way, when the take-up and pay-out device 100 is paying out the cable, the magnetic field of the magnetic structure 20 is weakened by the control device 30, so that the magnetic cable 10 is separated from the magnetic structure 20 to achieve pay-out. When the take-up and pay-out device 100 is taking up the cable, the magnetic field of the magnetic structure 20 is strengthened by the control device 30, so that the magnetic cable 10 is adsorbed to the magnetic structure 20 to achieve take-up. In this way, the pay-out resistance can be reduced by weakening the magnetic field of the magnetic structure 20 when paying out the cable, and the magnetic cable 10 can be quickly and closely wound around the magnetic structure 20 by strengthening the magnetic field of the magnetic structure 20 when taking up the cable, thereby facilitating the take-up and pay-out of the cable.

[0054] In an embodiment, the magnetic layer 11 is arranged in the magnetic cable 10.

[0055] In the embodiment, as shown in FIGS. 2-4 and 8, the magnetic layer 11 is arranged in the magnetic cable 10, so that the cable has magnetism, and the magnetic cable 10 can be adsorbed on the magnetic structure 20. It can be understood that the magnetic cable 10 can form different winding modes according to different magnetic structures 20. For example, when the magnetic structure 20 is a magnetic plate 21 structure, the magnetic cable 10 is adsorbed and wound on one side surface of the magnetic plate 21. When the magnetic structure 20 is a magnetic core 22 structure, the magnetic cable 10 is adsorbed and wound on the outer circumferential surface of the magnetic core 22. In this way, the cable can be arranged in order and closely attached during winding and unwinding.

[0056] In an embodiment, the magnetic layer 11 is provided with a first cavity 111 in the axial direction of the magnetic cable 10, and the wire 12 is arranged in the first cavity 111.

[0057] In the embodiment, as shown in FIGS. 2 and 3, the magnetic cable 10 is arranged in a manner that the wire 12 is wrapped by the magnetic layer 11 on the outer periphery, so that the magnetic layer 11 is located on the outer periphery of the magnetic cable 10. When the take-up and pay-off device 100 winds the cable, the magnetic layer 11 of the magnetic cable 10 can directly contact the magnetic structure 20, so that there is sufficient magnetic attraction between them.

[0058] In order to protect the magnetic layer 11 and prevent the magnetic layer 11 from being worn, in an embodiment, as shown in FIG. 3, the magnetic layer 11 is further wrapped by an outer sheath layer 13. It can be understood that the outer sheath layer 13 is wrapped on the outer surface of the magnetic layer 11, so as to protect the magnetic layer 11 and prevent the magnetic layer 11 from being worn.

[0059] In an embodiment, the magnetic layer 11 is located on the side of the magnetic cable 10 facing the magnetic structure 20.

[0060] In the embodiment, as shown in FIG. 8, the magnetic layer 11 is arranged on the side of the magnetic cable 10 facing the magnetic structure 20, so that when the take-up and pay-off device 100 winds the cable, the magnetic layer 11 of the magnetic cable 10 can directly contact the magnetic structure 20, so that there is sufficient magnetic attraction between them. Alternatively, the magnetic structure 20 is a magnetic core 22.

[0061] In an embodiment, the magnetic cable 10 includes an outer sheath layer 13, a wire 12 and a soft magnetic iron 14. The outer sheath layer 13 is provided with a second cavity 131 extending in the axial direction thereof, the wire 12 is arranged in the second cavity 131, and the soft magnetic iron 14 is embedded in the outer sheath layer 13 and spaced from the second cavity 131.

[0062] In the embodiment, as shown in FIG. 4, the outer sheath layer 13 of the magnetic cable 10 is provided with a cavity in the axial direction, the wire 12 is arranged in the cavity, and the soft magnetic iron 14 is embedded in the outer sheath layer 13. It can be understood that, by arranging the magnetic cable 10 in the manner that the wire 12 is wrapped by the outer sheath layer 13, and the soft magnetic iron 14 is embedded in the outer sheath layer 13, the outer diameter of the entire magnetic cable 10 can be reduced, while the wear resistance of the magnetic cable 10 is ensured. Optionally, the soft magnetic iron 14 extends in the axial direction of the second cavity 131.

[0063] In an embodiment, the soft magnetic iron 14 includes a plurality of soft magnetic irons 14, each of which is embedded in the outer sheath layer 13 and spaced from the second cavity 131, and the plurality of soft magnetic irons 14 are arranged in the circumferential direction of the second cavity 131.

[0064] In the embodiment, as shown in FIG. 4, the soft magnetic iron 14 optionally includes a plurality of soft magnetic irons 14. For example, the soft magnetic iron 14 can be two, three, four, five or more. The plurality of soft magnetic irons 14 are each embedded in the outer sheath layer 13, and the plurality of soft magnetic irons 14 are each arranged in the circumferential direction of the second cavity 131. Of course, the plurality of soft magnetic irons 14 are each embedded in the outer sheath layer 13, and the plurality of soft magnetic irons 14 are each arranged in the axial direction of the magnetic cable 10, which is not limited herein.

[0065] Optionally, the soft magnetic iron 14 includes four soft magnetic irons 14. In the embodiment, as shown in FIG. 4, the number of the soft magnetic irons 14 is four, and the four soft magnetic irons 14 are arranged in the circumferential direction of the outer sheath layer 13. Optionally, each of the soft magnetic irons 14 extends in the axial direction of the magnetic cable 10.

[0066] It can be understood that, by arranging the plurality of soft magnetic irons 14 in the circumferential direction of the outer sheath layer 13, the magnetic force of the circumferential surface of the magnetic cable 10 can be uniform, and each of the soft magnetic irons 14 can be adsorbed to the magnetic plate 21.

[0067] In an embodiment, the magnetic structure 20 is a magnetic plate 21, and the magnetic plate 21 has a first surface 211. When the take-up and pay-off device 100 winds up the wire, the magnetic cable 10 is wound outwards from a fixed point on the first surface 211.

[0068] In the embodiment, the magnetic structure 20 can be a magnetic plate 21 as shown in FIG. 1, FIG. 2 and FIG. 5. It can be understood that the magnetic plate 21 has a first surface 211, and the bottom surface of the magnetic cable 10 is opposite to the magnetism of the first surface 211, so that the bottom surface of the magnetic cable 10 is tightly attached to the first surface 211 of the magnetic plate 21. Thus, during the winding and unwinding of the magnetic cable 10 by the winding and unwinding device 100, when the winding and unwinding device 100 unwinds, the surface magnetism of the magnetic plate 21 is weakened by the control device 30 to reduce the magnetic force between the magnetic plate 21 and the magnetic cable 10, thereby accelerating the unwinding. When the winding and unwinding device 100 winds, the surface magnetism of the magnetic plate 21 is strengthened by the control device 30 to strengthen the magnetic force between the magnetic plate 21 and the magnetic cable 10, so that the magnetic cable 10 is tightly attached to the magnetic plate 21, thereby accelerating the winding. Thus, by controlling the strength of the magnetism of the magnetic plate 21, the winding and unwinding speed is accelerated, and automatic winding and unwinding is achieved.

[0069] It can be understood that, as shown in FIG. 1, FIG. 2 and FIG. 5, the first surface 211 of the magnetic plate 21 has a fixed point, and when the winding and unwinding device 100 winds, the magnetic cable 10 is tightly wound outward from the fixed point on the first surface 211, so that the magnetic cable 10 is wound in a flat spiral line on the first surface 211, the winding radius of the magnetic cable 10 increases from small to large, and the magnetic cable 10 is arranged in order without overlapping, thereby facilitating winding and unwinding. At the same time, the tight winding of the magnetic cable 10 also causes the adjacent magnetic cable segments to be attracted to each other, thereby further facilitating winding and unwinding.

[0070] Alternatively, the magnetic plate 21 is an electromagnetic plate. In the embodiment, the size of the magnetic field of the electromagnetic plate can be controlled and adjusted by the control device 30 by controlling the current of the electromagnetic plate. It can be understood that the greater the current, the greater the magnetic force in the magnetic field of the electromagnetic plate 21, and the greater the attraction force of the magnetic cable 10; the smaller the current, the smaller the magnetic force in the magnetic field of the electromagnetic plate 21, and the smaller the attraction force of the magnetic cable 10.

[0071] In the embodiment, when the winding and unwinding device 100 unwinds, the control device 30 can control the current in the magnetic plate 21 to be less than a threshold value, so that the magnetic cable 10 can be separated from the surface of the electromagnetic plate under a smaller external force, thereby facilitating unwinding; when the winding and unwinding device 100 winds, the control device 30 can control the current in the magnetic plate 21 to be greater than a threshold value, so that the magnetic cable 10 can be tightly attached to the surface of the magnetic plate 21, thereby facilitating winding.

[0072] In an embodiment, the magnetic structure 20 is a magnetic core 22, and the magnetic core 22 is in a columnar shape; wherein the magnetic cable 10 is spirally wound around the outer peripheral surface of the magnetic core 22 when the winding and unwinding device 100 winds.

[0073] In the embodiment, as shown in FIGS. 6-8, the magnetic structure 20 is arranged as a magnetic core 22 in a columnar shape, so that the magnetic cable 10 can be received on the magnetic core 22, and the magnetic cable 10 is arranged in order and closely attached when being wound or unwound. It can be understood that the control device 30 is connected to the magnetic core 22, and the magnetic field of the magnetic core 22 is weakened to reduce the resistance when the cable is unwound, and the magnetic field of the magnetic core 22 is strengthened to make the magnetic cable 10 quickly and closely attach to the magnetic core 22 when the cable is wound, so that the cable can be conveniently wound or unwound.

[0074] It can be understood that, as shown in FIGS. 6-8, the magnetic core 22 is in a columnar shape, and the columnar magnetic core 22 has an outer circumferential surface, and the magnetic cable 10 is spirally wound around the outer circumferential surface of the magnetic core 22, so that the magnetic cable 10 is wound around the magnetic core 22 as the center, the magnetic cable 10 is closely attached to the magnetic core 22 after being wound, the winding radius of the magnetic cable 10 is consistent, and the magnetic cable 10 is arranged in order.

[0075] Optionally, the bottom surface of the magnetic cable 10 and the outer circumferential surface of the magnetic core 22 have opposite magnetism, so that the bottom surface of the magnetic cable 10 is closely attached to the outer circumferential surface of the magnetic core 22. During the winding or unwinding of the cable by the cable winding and unwinding device 100, the magnetic property of the surface of the magnetic core 22 is weakened by the control device 30 when the cable is unwound, so that the magnetic force between the magnetic core 22 and the magnetic cable 10 is reduced, thereby accelerating the unwinding. When the cable is wound, the magnetic property of the surface of the magnetic core 22 is strengthened by the control device 30, so that the magnetic force between the surface of the magnetic core 22 and the surface of the magnetic cable 10 is strengthened, and the magnetic cable 10 is closely attached to the magnetic core 22, thereby accelerating the winding. In this way, the strength of the magnetic property of the magnetic core 22 is controlled, the winding or unwinding speed is accelerated, and the automatic winding or unwinding is realized.

[0076] In the embodiment, the magnetic core 22 can be an electromagnetic core. It can be understood that the current of the electromagnetic core 22 is controlled by the control device 30, so that the magnetic field of the magnetic core 22 can be controlled and adjusted. The greater the current, the greater the magnetic force in the magnetic field of the electromagnetic core 22, and the greater the adsorption force of the magnetic cable 10. The smaller the current, the smaller the magnetic force in the magnetic field of the electromagnetic core 22, and the smaller the adsorption force of the magnetic cable 10.

[0077] It can be understood that, when the cable is unwound by the cable winding and unwinding device 100, the current in the magnetic core 22 is controlled by the control device 30 to be less than a threshold value, so that the magnetic cable 10 can be separated from the outer circumferential surface of the magnetic core 22 under a smaller external force, thereby facilitating the unwinding. When the cable is wound by the cable winding and unwinding device 100, the current in the magnetic core 22 is controlled by the control device 30 to be greater than a threshold value, so that the magnetic cable 10 can be closely attached to the outer circumferential surface of the magnetic core 22, thereby facilitating the winding.

[0078] In an embodiment, the control device 30 comprises a power supply structure 31 and a control structure 32, the power supply structure 31 is connected with the magnetic structure 20 through a cable and is configured to supply current to the magnetic structure 20, and the control structure 32 is electrically connected with the power supply structure 31 and is configured to control the current supplied by the power supply structure 31 to the magnetic structure 20.

[0079] In the embodiment, as shown in FIG. 5, the control device 30 is configured as the power supply structure 31 and the control structure 32, the power supply structure 31 is electrically connected with the magnetic structure 20, for example, the power supply structure 31 is connected with the magnetic structure 20 through a cable, so that the power supply structure 31 supplies power or current to the magnetic structure 20, and the control structure 32 controls the current supplied by the power supply structure 31 to the magnetic structure 20, so as to control and adjust the magnetic field strength of the magnetic structure 20.

[0080] It can be understood that the power supply structure 31 can be a mobile power supply or an external circuit. The control structure 32 can be a controller, a control button, a control valve, or the like, and the control structure 32 can also be a circuit board integrated with a control circuit or a control program, which is not limited herein. In the embodiment, the control structure 32 can be electrically connected or signal connected with the power supply structure 31, and the control signal of the control structure 32 controls the current supplied by the power supply structure 31 to the magnetic structure 20.

[0081] In an embodiment, the control structure 32 is further configured to control the current direction supplied by the power supply structure 31 to the magnetic structure 20, so as to adjust the polarity direction of the magnetic structure 20.

[0082] It can be understood that the current in the magnetic structure 20 generates a magnetic field around it, and the strength of the magnetic field is proportional to the strength of the current.
