Description

Technical Field

[0001] This application relates to the technical field of slip rings, and in particular to a slip ring assembly and slip shaft driven by electromagnetic induction. Background Technology

[0002] Currently, the slip differential shaft of a slitting machine refers to a slip differential shaft specifically used on slitting machines. The slip differential shaft consists of a ventilation shaft and multiple sets of slip differential rings. By utilizing the principle that each slip differential ring on the slip differential shaft slips independently, the tension of each roll is precisely controlled, ensuring that multiple rolls on the ventilation shaft remain uniform, neat, and with constant tension during the winding process, thus guaranteeing the quality of winding.

[0003] Most slip rings are configured as air-expanded slip rings, which generate friction and slip force based on the relative rotation between adjacent components. Since the friction generated by pneumatics is easily affected by changes in the external environment, its friction coefficient changes, which causes the slip force generated by the slip ring to fluctuate, thus affecting the stability of the slitting machine operation. Summary of the Invention

[0004] To improve the problem of unstable slip force generated by the air-expanded slip shaft, this application provides an electromagnetic induction driven slip ring assembly and slip shaft.

[0005] The slip ring assembly provided in this application adopts the following technical solution:

[0006] The slip ring includes a magnetic component and a conductor structure that abut against each other along the axial direction. The conductor structure includes a conductor made of a conductive non-magnetic material. The magnetic component includes multiple sets of magnets arranged at uniform intervals along the circumference. The multiple sets of magnets are configured to generate multiple sets of closed magnetic field lines. The slip ring group includes a first slip ring and a second slip ring arranged at intervals. The first slip ring includes a first magnetic component with a first magnet and a first conductor component with a first conductor. The second slip ring includes a second magnetic component with a second magnet and a second conductor component with a second conductor. The first conductor and the second magnet are spaced apart and at least partially opposite each other, and the rotational speed of the second magnet is greater than the rotational speed of the first conductor, thereby causing the first conductor to be subjected to an outward driving force, which in turn drives a winding component disposed outside the first conductor component to move. Alternatively, the first magnet and the second conductor are spaced apart and at least partially opposite each other, and the rotational speed of the first magnet is greater than the rotational speed of the second conductor, thereby causing the second conductor to be subjected to an outward driving force, which in turn drives a winding component disposed outside the second conductor component to move.

[0007] By employing the above scheme, the rotational speed of the second magnet is greater than the rotational speed of the first conductor, thereby causing the first conductor to be subjected to an outward driving force, which in turn drives the winding assembly disposed outside the first conductor assembly to move. Alternatively, the first magnet and the second conductor are spaced apart and at least partially facing each other, and the rotational speed of the first magnet is greater than the rotational speed of the second conductor, thereby causing the second conductor to be subjected to an outward driving force, which in turn drives the winding assembly disposed outside the second conductor assembly to move. The driving force of the first conductor assembly or the second conductor assembly originates from the Lorentz force generated by electromagnetic induction. The Lorentz force is mainly determined by the rotational speed of the conductor structure and the magnetic induction intensity generated by the magnet, and is not affected by changes in the external environment. Therefore, the resulting slip force is more stable and suitable for use in high-precision, low-tension slitting machines, such as diaphragms and termination tapes.

[0008] Optionally, the axial spacing between the first differential ring and the second differential ring is 0.5mm to 1mm.

[0009] By adopting the above technical solution, the conductor and its adjacent magnet are controlled at a suitable interval, which is conducive to the relative movement of the conductor in a suitable magnetic field strength, thereby generating a stable and suitable slip force.

[0010] Optionally, the magnetic component includes a carrier, the carrier including a plurality of circumferentially spaced first slots, the interior of the first slots accommodating a group of magnets with different polarities, and the ends of adjacent first slots accommodating magnets with different polarities.

[0011] By adopting the above technical solution, multiple sets of magnets are fixed on the end face of the carrier adjacent to the conductor. The magnets with different polarities are accommodated at the ends of adjacent first slots, so that the magnets with different polarities at the ends of adjacent first slots generate several closed magnetic field lines. Furthermore, the multiple sets of magnets are arranged at intervals along the circumference of the carrier, so that the magnetic induction intensity generated by the multiple sets of magnets at various points along the circumference of the carrier is stable during the rotation of the carrier. As a result, the Lorentz force experienced by the conductor during relative rotation is balanced.

[0012] Optionally, the carrier includes eight first slots spaced circumferentially, and the interior of the eight first slots accommodates eight sets of magnets.

[0013] By adopting the above technical solution, it is beneficial to uniformly divide and arrange eight groups of magnets along the circumference of the carrier.

[0014] Optionally, the carrier further includes a plurality of second grooves, the interior of which accommodates a piston, the piston abutting against the conductor structure, and the first groove and the second groove are offset from each other along the circumference of the carrier.

[0015] By adopting the above technical solution, the first groove and the second groove are staggered along the circumference of the support body, which helps to improve the structural strength of the support body itself.

[0016] Optionally, the conductor includes an annular sensing portion configured to generate magnetic induction with a nearby magnet.

[0017] By adopting the above technical solution, it is beneficial to arrange the conductor and its adjacent multiple sets of magnets facing each other, and to make the conductor subject to a stable Lorentz force during relative rotation.

[0018] Optionally, the conductor structure further includes a retaining ring, and the conductor further includes a snap-fit ​​portion, which is sleeved on the outside of the retaining ring; the conductor structure further includes a C-shaped ring disposed between the retaining ring and the snap-fit ​​portion.

[0019] By adopting the above technical solution, it is beneficial for the conductor to be stably arranged on the outside of the fixed ring. At the same time, the C-shaped ring has a notch structure, which can provide radial tension, which is beneficial for the conductor structure to drive outward.

[0020] Optionally, the conductor structure further includes a wedge base disposed on the outside of the fixing ring and a plurality of wedge blocks surrounding the wedge base, wherein a plurality of protrusions are provided on the outer surface of the wedge blocks.

[0021] By adopting the above technical solution, the wedge block is provided with multiple protrusions, which are beneficial to increasing the friction between the wedge block and the winding assembly, thereby facilitating the wedge block to drive the winding assembly.

[0022] Optionally, the retaining ring includes a first bearing, a retaining ring, and a second bearing with different wall thicknesses, wherein the first bearing and the retaining ring are arranged axially, and the retaining ring and the second bearing are arranged radially.

[0023] By adopting the above technical solution, it is beneficial to improve the structural strength of the conductor structure itself and to facilitate the fixing of other components on the outside of the fixing ring.

[0024] Optionally, the slip ring further includes a tensioner, a portion of which is embedded inside the conductor structure, and another portion of which is disposed between the magnetic component and the conductor structure.

[0025] By adopting the above technical solution, a tensioning seat is set at the connection between the conductor structure and the magnetic component. The tensioning seat is preferably configured as an elastic washer. The elasticity of the tensioning seat itself helps to improve the connection strength between the conductor structure and the magnetic component.

[0026] This application also provides a slip shaft, the slip shaft including a rotating shaft and a plurality of slip rings arranged axially along the rotating shaft, wherein each slip ring group includes the above-mentioned slip ring group. Attached Figure Description

[0039] To facilitate understanding of this application, a further detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0041] This application discloses slip ring assemblies, as shown in the embodiments below. Figure 1 As shown, the differential ring assembly includes a first differential ring 100 and a second differential ring 200 arranged axially at intervals. The first differential ring 100 and the second differential ring 200 have the same structure. Each differential ring includes a magnetic component 10 and a conductor structure 20 that abut against each other along its axial direction. The magnetic component 10 and the conductor structure 20 are both sleeved on the central rotating shaft of the differential shaft.

[0042] Reference Figures 2 to 7As shown, the magnetic component 10 includes a carrier 11, which is generally annular in shape. The central hole of the carrier 11 is used for the central rotating shaft of the slip ring to pass through. The carrier 11 also includes a first outer surface 111 and a second outer surface 112 disposed opposite to each other. The first outer surface 111 is configured as an outer surface of the slip ring, and the second outer surface 112 is attached to one side of the conductor structure 20 along the central axis.

[0043] Further reference Figure 2 As shown, a plurality of first grooves 113 are provided on the first outer surface 111 of the support body 11. The plurality of first grooves 113 are arranged at uniform intervals along the circumference of the support body 11. Each first groove 113 contains a set of magnets 30. Each set of magnets 30 includes an N-pole magnet and an S-pole magnet. Both the N-pole magnet and the S-pole magnet are configured as cylinders. Each first groove 113 is approximately waist-shaped, so that each first groove 113 can provide a holding function for the set of magnets 30. At the same time, the height of the magnets 30 is slightly greater than the depth of the first groove 113, so that each N-pole magnet and each S-pole magnet protrudes relative to the top surface of the first groove 113.

[0044] In one example provided in this application, eight first grooves 113 are provided on the first outer surface 111 of the carrier 11, and eight sets of magnets 30 are fixed on the carrier 11 accordingly. Magnets 30 with different polarities are provided at the adjacent ends of two adjacent first grooves 113, and S-pole magnets and N-pole magnets are respectively provided at the adjacent ends of two adjacent first grooves 113.

[0045] Further reference Figure 5 As shown, a plurality of second grooves 114 are provided on the second outer surface 112 of the support body 11. The plurality of second grooves 114 are arranged at uniform intervals along the circumference of the support body 11. Each second groove 114 contains a piston 40. A sealing sleeve 41 is fitted on the outer wall of each piston 40. The sealing sleeve 41 helps to fix the piston 40 inside the second groove 114.

[0046] In a preferred embodiment, the number of first slots 113 and second slots 114 is the same. When the number of first slots 113 is configured to be eight, the number of second slots 114 is also configured to be eight. The opening direction of the first slots 113 is opposite to the opening direction of the second slots 114. Furthermore, the first slots 113 and second slots 114 are staggered along the circumference of the support body 11. There is one second slot 114 between two adjacent first slots 113, or there are two first slots 113 between two adjacent second slots 114. The staggered arrangement of the first slots 113 and second slots 114 is beneficial to improving the structural strength of the support body 11.

[0047] Furthermore, the carrier 11 also includes an inner surface 115 defining its central hole, on which one or more sealing rings 12 are provided, wherein the multiple sealing rings 12 are axially spaced, and the sealing rings 12 facilitate the rotational connection between the carrier 11 and the central rotating shaft of the slip shaft.

[0048] A groove 116 is also provided on the inner surface 115 of the support body 11, and a notch 117 is provided at the bottom of the groove 116. The notch 117 is connected to the second groove 114, so that the protruding part of the end of the piston 40 can be inserted into the groove 116 through the notch 117, further enhancing the holding force of the piston 40 on the support body 11. The groove 116 is located between the two sealing rings 12.

[0049] Reference Figures 2 to 7 As shown, the conductor structure 20 includes a first bearing 21 and a fixing ring 22 with different wall thicknesses. The first bearing 21 and the fixing ring 22 are coaxially arranged with the carrier 11. The wall thickness of the first bearing 21 is greater than the wall thickness of the fixing ring 22. The fixing ring 22 is located between the first bearing 21 and the carrier 11. One end of the fixing ring 22 abuts against one end face of the carrier 11, and the other end of the fixing ring 22 abuts against one end face of the first bearing 21.

[0050] The conductor structure 20 also includes a conductor 23 sleeved on the outside of the first bearing 21. The conductor 23 is preferably made of a non-ferromagnetic metal material with low resistivity. Suitable metal materials include copper, gold, silver and aluminum or their alloys. When it moves in a changing magnetic field, it will generate a large current. In a preferred embodiment, the conductor 23 is made of aluminum material, which is beneficial to saving costs.

[0051] Further, refer to Figure 6 As shown, the conductor 23 includes a sensing part 231 and a snap-fit ​​part 232, wherein the sensing part 231 has an annular outer surface and is configured as the outer surface of the conductor structure 20, and the snap-fit ​​part 232 includes an inner flange 233 and an annular groove 234 provided on the inner surface of the conductor 23, wherein the inner flange 233 snaps onto the top surface of the first bearing 21.

[0052] Furthermore, a C-ring 24 is provided between the conductor 23 and the first bearing 21. A portion of the C-ring 24 is embedded inside the groove 234, and the other portion of the C-ring 24 is engaged with the bottom end face of the first bearing 21. Due to the notched structure, the C-ring 24 has an elastic force that contracts radially. This facilitates the installation of the C-ring 24 between the conductor 23 and the first bearing 21, and also allows the conductor 23, which abuts against the outside of the C-ring 24, to expand and contract radially.

[0053] The conductor structure 20 also includes a second bearing 25 disposed outside the fixed ring 22. The wall thickness of the second bearing 25 is greater than the wall thickness of the fixed ring 22, and the axial length of the second bearing 25 is less than the axial length of the fixed ring 22. A boss structure is provided on the outer surface of the fixed ring 22, and the inner side of the second bearing 25 abuts against a portion of the boss surface of the fixed ring 22.

[0054] The conductor structure 20 also includes a wedge base 26, the inner side of which is provided with a first flange 261, which is engaged with the top surface of the second bearing 25. The inner side of the wedge base 26 above the first flange 261 abuts against the side wall of the conductor 23, and the inner side of the wedge base 26 below the first flange 261 abuts against the outer side of the second bearing 25.

[0055] Multiple wedge-shaped grooves 262 are provided on the outer surface of the wedge base 26, and the multiple wedge-shaped grooves 262 are evenly distributed along the circumference of the wedge base 26.

[0056] The conductor structure 20 also includes a plurality of wedge blocks 27, which are housed inside the wedge groove 262. A plurality of protrusions 271 are provided on the outer surface of the wedge blocks 27, which makes the outer surface of the wedge blocks 27 more wear-resistant. During the contact between the slip shaft and the barrel, the contact between the outer surface of the wedge blocks 27 and the inner surface of the barrel is mainly achieved by the contact between the outer surface of the wedge blocks 27 and the barrel. The provision of a plurality of protrusions 271 on the outer surface of the wedge blocks 27 helps to increase the friction between the wedge blocks 27 and the barrel and enhance the cooperation force between the two.

[0057] The conductor structure 20 also includes a fastening ring 272 which surrounds a plurality of wedge blocks 27 and a wedge base 26 and provides circumferential restraint to prevent the wedge blocks 27 from separating from the wedge base 26.

[0058] The conductor structure 20 also includes a tensioning seat 28. A portion of the tensioning seat 28 is engaged between the fixing ring 22 and the second bearing 25. Another portion of the tensioning seat 28 is engaged between the bottom end face of the second bearing 25 of the magnetic assembly 10, the bottom end face of the wedge base 26, the top end face of the carrier 11 of the conductor structure 20, and the top end face of the piston 40. The tensioning seat 28 is preferably configured as an elastic washer, and the elasticity of the elastic washer itself makes a tight connection between the conductor structure 20 and the magnetic assembly 10.

[0059] Further reference Figure 1 , Figure 8As shown in Figure 10, in the slip ring assembly provided in the embodiments of this application, an axial interval d is provided between the first slip ring 100 and the second slip ring 200, and the conductor 23 of the conductor structure 20 of the first slip ring 100 and the plurality of magnets 30 on the carrier 11 of the magnetic component 10 of the second slip ring 200 are arranged facing each other. When the barrel is fixed on the outer surface of the wedge block 27 of the conductor structure 20 of the first slip ring 100, the conductor structure 20 of the first slip ring 100 has a slower rotation speed relative to the magnetic component 10 of the second slip ring 200, so that the magnets 30 on the second slip ring 200 rotate relative to the conductors 23 on the first slip ring 100, thereby causing the conductors 23 on the first slip ring 100 to cut magnetic field lines in the magnetic field generated by the magnets 30 of the second slip ring 200. Furthermore, the rotational speed of the magnet 30 of the second slip ring 200 is faster than the rotational speed of the conductor 23 of the first slip ring 100. This is equivalent to the magnetic field generated by the magnet 30 of the second slip ring 200 cutting the conductor 23, causing the conductor 23 to generate an induced current. Furthermore, when the conductor 23 generates an induced current, the conductor 23 is equivalent to several oriented moving charges. The moving charges will be further subjected to the Lorentz force in the magnetic field, that is, the conductor 23 will be subjected to the Lorentz force. According to Ampere's law and the determination rule of the Lorentz force, the conductor 23 will be subjected to the Lorentz force in its radial direction, thereby pushing the conductor 23 to move radially outward, which in turn pushes the inclined wedge base 26 and the wedge block 27 abutting against the outside of the conductor 23 to move radially outward, thereby driving the winding assembly to move.

[0060] According to the Lorentz force calculation rule, f = |q|vBsinθ, where q and v are the charge and velocity of the point charge, respectively; B is the magnetic induction intensity at the point charge location; and θ is the angle between v and B. In the embodiment of this application, θ is 90 degrees, and sinθ equals 1. Therefore, f = |q|vB. Since the multiple magnets 30 are evenly spaced along the circumference of the magnetic component 10, B is a constant value during the uniform rotation of the magnetic component 10. Correspondingly, the relative rotational speed between the conductor 23 and the magnet 30 is constant, so v is constant. The induced current generated by the conductor 23 is also constant, so q is constant. Consequently, the Lorentz force generated is also stable, and the outward driving force on the conductor 23 is also stable, thus making the winding quality of the winding component more stable.

[0061] In embodiments of this application, a slip ring assembly is provided, wherein a first slip ring 100 includes a first magnetic component 110 and a first conductor component 120, and a second slip ring 200 includes a second magnetic component 210 and a second conductor component 220. The first magnetic component 110 has a first magnet 130, the first conductor component 120 has a first conductor 123, the second magnetic component 210 has a second magnet 230, and the second conductor component 220 has a second conductor 223.

[0062] It should be noted that the magnetic component 10 of the slip ring can be configured to be disposed at the upper end of the conductor structure 20. In this case, the first conductor 123 of the first slip ring 100 and the second magnet 230 of the second slip ring 200 are arranged facing each other, and a magnetic induction driving effect is formed between the first conductor 123 and the second magnet 230. In other optional examples, the conductor structure 20 of the slip ring is disposed at the upper end of the magnetic component 10. In this case, the first magnet 130 of the first slip ring 100 and the second conductor 223 of the second slip ring 200 are arranged facing each other, and a magnetic induction driving effect is formed between the first magnet 130 and the second conductor 223.

[0063] A suitable axial distance d is provided between the first slip ring 100 and the second slip ring 200, wherein the suitable axial distance ranges from 0.5 mm to 1 mm. This suitable axial distance d ensures that the first conductor 123 on the first slip ring 100 and the second magnet 230 on the adjacent second slip ring 200 are kept at a suitable distance, or that the first magnet 130 on the first slip ring 100 and the second conductor 223 on the adjacent second slip ring 200 are kept at a suitable distance. This facilitates relative movement of the conductors within a suitable magnetic field strength, thereby generating a stable and suitable slip force. It should be noted that the axial distance d between the first slip ring 100 and the second slip ring 200 can be any range or any value between 0.5 mm and 1 mm, and is not listed in the embodiments of this application.

[0064] Please see Figure 10 In the second embodiment provided in this application, a slip shaft 300 is also provided. The slip shaft 300 includes a rotating shaft 310 arranged at the center and multiple sets of the above-mentioned slip rings arranged along the axial direction of the rotating shaft 310. Each set of slip rings includes a first slip ring 100 and a second slip ring 200 arranged at intervals. The first slip ring 100 and the adjacent second slip ring 200 have a magnetic induction driving effect, and the second slip ring 200 and the adjacent first slip ring 100 also form a magnetic induction driving effect, thereby enabling the slip shaft to synchronously drive multiple sets of winding components.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
