Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to an adjustment component and an electrode conveying device. Background Technology

[0002] During battery production, the electrodes are supported on adjusting components to ensure their flatness. However, during the electrode transport process, the electrodes supported on the adjusting components tend to become loose on one side and taut on the other, which affects the product yield. Summary of the Invention

[0003] The main objective of this invention is to provide an adjusting element and an electrode conveying device, which aims to solve the problem of inconsistent tightness on both sides of the electrode during the conveying process.

[0004] To achieve the above objectives, the present invention provides an adjusting component comprising a fixed shaft, a plurality of arc-shaped components, a wheel assembly, and a drive assembly. The plurality of arc-shaped components are arranged around the fixed shaft; each arc-shaped component has a first end and a second end opposite to each other. The wheel assembly includes a first wheel assembly and a second wheel assembly, the first end being driveably connected to the first wheel assembly, and the second end being connected to the second wheel assembly. The drive assembly is driveably connected to the wheel assembly and causes the arc-shaped components to expand or contract radially.

[0005] The technical solution of this invention arranges multiple arc-shaped components around a fixed axis, allowing the electrode sheet to be supported on these components and conveyed by them as they rotate around the fixed axis. A first wheel assembly is driven to a first end, and a second end is connected to a second wheel assembly, enabling both to rotate together with the arc-shaped components. A drive assembly is driven to the wheel assembly, allowing the arc-shaped components to expand or contract radially. This changes the radial dimension of the roller formed by the first ends of the multiple arc-shaped components, adapting to the tension of the electrode sheet at that location. This ensures that the adjustment mechanism provides consistent support tension for the electrode sheet near the first end as it does for the electrode sheet near the second end of the arc-shaped component.

[0006] In one embodiment, the drive assembly is connected to the first wheel assembly and drives the first wheel assembly to move axially along the fixed shaft, so that the first end can move radially with the second end as the fulcrum.

[0007] By driving the first wheel assembly axially, and then driving the first end to move radially along the fixed shaft with the second end as a fulcrum, the space required for the drive assembly between the first wheel assembly and the fixed shaft, or between the arc-shaped component and the fixed shaft, can be reduced. This arrangement also allows the axial movement of one first wheel assembly to drive all connected arc-shaped components to move radially along the fixed shaft simultaneously, improving drive efficiency and cost, and reducing the need for individual drive of each arc-shaped component. By using the second end as a fulcrum and moving radially along the fixed shaft, multiple first ends can expand away from or converge towards the fixed shaft. This allows for consistent adjustment of the tension of the roller's support on the electrode plates at both ends by adjusting the radial dimension of a single roller, improving adjustment efficiency and accuracy.

[0008] In one embodiment, one of the first end and the first wheel assembly is provided with an inclined groove, and the other of the first end and the first wheel assembly is provided with a first pin, which is slidably disposed in the inclined groove.

[0009] This configuration allows the arc-shaped component to move radially away from or towards the fixed axis through the abutting action between the first pin and the wall of the inclined slide groove. Furthermore, by employing a structure where the first pin slides within the inclined slide groove, the need for a sliding block to connect the arc-shaped component to the first wheel assembly is reduced, thus simplifying the transmission structure and lowering its space occupancy.

[0010] In one embodiment, the first wheel assembly is provided with a plurality of first slots arranged circumferentially along the first wheel assembly, and the first slot has a first opening facing the second wheel assembly, the first end being inserted into the first slot; the first pin is provided on the side wall of the first slot, and the inclined groove is provided on the first end.

[0011] This design reduces the space occupied by the adjusting component in the radial direction of the fixed shaft, thus providing good protection for the first pin and the inclined slide.

[0012] In one embodiment, the first wheel assembly includes a first wheel body and a first bearing. The first wheel body is tractively connected to the first end. The first bearing is sleeved outside the fixed shaft; the first wheel body is sleeved outside the first outer ring of the first bearing, and the drive assembly is tractively connected to the first inner ring of the first bearing, driving the first bearing to move axially.

[0013] This configuration reduces the friction when the first disc rotates; it also allows the roller to drive the first disc and the first outer ring of the bearing to rotate, while the first inner ring of the bearing does not rotate, thus preventing the drive assembly from rotating. This ensures the drive assembly has good stability and reduces the risk that the rotation of the drive assembly will affect the driving effect of the bearing.

[0014] In one embodiment, the drive assembly includes a sleeve assembly sleeved outside the fixed shaft, the sleeve assembly being axially movable on the fixed shaft; the first inner ring of the first bearing is fixedly sleeved outside the sleeve assembly.

[0015] This configuration reduces wear between the first bearing and the fixed shaft, thereby ensuring that the first outer ring of the first bearing can rotate stably relative to the first inner ring, which in turn ensures the stability of the rotation of the first wheel disc body and the roller, and reduces the risk of the electrode plates on the roller shaking.

[0016] In one embodiment, the sleeve assembly includes a threaded sleeve, the fixed shaft is provided with an external thread, and the threaded sleeve is threadedly engaged with the external thread.

[0017] This configuration ensures that the rotation of the roller will not affect the rotation of the threaded sleeve, thus preventing the roller's radial dimension from changing at any time; and it also ensures that the roller will not be at risk of torsion when its radial dimension changes.

[0018] In one embodiment, the sleeve assembly is provided with a positioning hole, the axis of which is perpendicular to the axial direction of the sleeve assembly; the adjusting member further includes a positioning member, which passes through the positioning hole and is connected to the fixed shaft.

[0019] This configuration allows the sleeve assembly to be positioned on a fixed shaft, reducing the risk of the sleeve assembly rotating and / or moving relative to the fixed shaft, thereby ensuring that the roller can rotate stably under the friction of the electrode sheet.

[0020] In one embodiment, the positioning hole is a threaded hole; the positioning element is a positioning bolt, the positioning bolt is threadedly connected to the threaded hole, and the positioning bolt radially abuts against the fixed shaft.

[0021] This design reduces the risk of the positioning component easily falling out of the positioning hole, making the positioning more secure, and also allows for flexible adjustment of the supporting force against the fixed shaft.

[0022] In one embodiment, the sleeve assembly includes a sleeve body, a first limiting portion, and a second limiting portion. The sleeve body is sleeved outside the fixed shaft, and the first bearing is sleeved outside the sleeve body. The first limiting portion is fixedly disposed on the sleeve body and located on one side of the first bearing in the axial direction. The second limiting portion is fixedly disposed on the sleeve body and located on the other side of the first bearing in the axial direction.

[0023] This configuration reduces the risk of the first bearing sliding axially on the sleeve body, thereby improving the stability of the first inner ring of the first bearing moving synchronously with the sleeve body.

[0024] In one embodiment, both the first limiting portion and the second limiting portion abut against the first inner ring of the first bearing.

[0025] This configuration reduces the interference of the first and second limiting parts on the rotational movement of the first outer ring of the first bearing.

[0026] In one embodiment, the first wheel body is provided with a third limiting part and a fourth limiting part, which are respectively provided on opposite sides of the first outer ring of the first bearing.

[0027] With this configuration, when the first bearing moves along its axial direction, it can drive the first wheel body to move synchronously, avoiding the risk that the first wheel body cannot move with the first bearing when it moves in the axial direction.

[0028] In one embodiment, the second wheel assembly includes a second wheel body and a second bearing. The second end is connected to the second wheel body. The second bearing is fixedly sleeved outside the fixed shaft, and the second wheel body is sleeved outside the second bearing.

[0029] This design reduces friction when the second disc rotates and ensures that the second disc does not move axially on the fixed shaft, thus guaranteeing the stability of the arc-shaped component connected to the second disc assembly. This allows users to adjust the radial dimension of the roller only on one side of the roller closest to the first disc assembly, improving adjustment efficiency and accuracy.

[0030] In one embodiment, the second end is rotatably connected to the second wheel body, and the rotation axis of the second end extends along a first direction, which is perpendicular to both the axial direction and the radial direction of the fixed shaft.

[0031] With this configuration, when the first end of the arc-shaped component moves radially along the fixed axis with the second end of the arc-shaped component as the fulcrum, the second end of the arc-shaped component can rotate with the swing of the first end, thereby reducing the risk of the second end of the arc-shaped component being forcibly bent and deformed.

[0032] In one embodiment, the second wheel body is provided with a plurality of second slots, which are spaced apart circumferentially; the second slot has a second opening facing the first wheel assembly, and the second end of the arc-shaped member is rotatably disposed within the second slot.

[0033] This design reduces the space occupied by the adjusting component in the radial direction of the fixed shaft and provides good protection for the second end of the arc-shaped component.

[0034] The present invention also proposes an electrode conveying device, including the above-mentioned adjusting member. Attached Figure Description

[0048] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] In battery production, the flatness of the electrode sheets at critical locations affects the stability and efficiency of this process. For example, during laser die-cutting, if one side of the electrode sheet is relaxed while the other is taut, the tab on the relaxed side will easily deviate from the cutting focus, causing the laser to go out of focus and fail to cut the tab. This directly impacts the yield of the die-cutting machine, thus requiring the electrode sheets to be flat. In related technologies, the conveyor rollers are typically rollers with a fixed outer diameter. In actual production, even if the level of the conveyor rollers is adjusted to a certain precision, inconsistencies in tension may still exist on both sides of the electrode sheet.

[0053] To address the issue of inconsistent tightness on both sides of the electrode sheet during transport, this invention proposes an adjusting component.

[0054] Please refer to the reference. Figures 1 to 3 In one embodiment of the present invention, the adjusting member includes a fixed shaft 100, a plurality of arc-shaped members 200, a wheel assembly, and a drive assembly 400. The plurality of arc-shaped members 200 are arranged around the fixed shaft 100, and each arc-shaped member 200 has a first end 201 and a second end 202 opposite to each other. The wheel assembly includes a first wheel assembly 300 and a second wheel assembly 500, with the first end 201 being driveably connected to the first wheel assembly 300 and the second end 202 being connected to the second wheel assembly 500. The drive assembly 400 is driveably connected to the wheel assembly and causes the arc-shaped members 200 to expand or contract radially.

[0055] The fixed shaft 100 refers to a cylindrical shaft that is fixed in place. The axis of the fixed shaft 100 can serve as the rotation axis of the cylindrical roller 20 formed by multiple arc-shaped parts 200. Along the length of the fixed shaft 100, the diameter of the fixed shaft 100 is the same at all points, or the diameter of the middle part of the fixed shaft 100 is different from the diameter of the ends of the fixed shaft 100.

[0056] An arc-shaped component 200 refers to a component whose surface away from the fixed axis 100 is arc-shaped. Multiple arc-shaped components 200 are arranged around the fixed axis 100 to form a cylindrical structure, which is the roller 20. For example, the arc-shaped component 200 can be a sheet-like structure, or it can be a strip-like or columnar structure. The arc-shaped components 200 extend axially along the fixed axis 100. Multiple arc-shaped components 200 are arranged in a circular array to form the roller 20, which can carry the electrode sheet and drive the electrode sheet to move when the multiple arc-shaped components 200 rotate together around the fixed axis 100, or drive the multiple arc-shaped components 200 to rotate together around the fixed axis 100 when the electrode sheet moves. Specifically, there can be two, three, four, five, or more arc-shaped components 200. The arc-shaped component 200 has a first end 201 and a second end 202. The first end 201 is close to one end of the fixed shaft 100, and the second end 202 is close to the other end of the fixed shaft 100. That is, the direction from the first end 201 to the second end 202 of the arc-shaped component 200 extends along the axial direction of the fixed shaft 100.

[0057] A wheel assembly is a component that can rotate around a fixed axis 100 and can be connected to the arc-shaped component 200 for transmission.

[0058] The first wheel assembly 300 refers to a disc assembly used for transmission connection with the first ends 201 of multiple arc-shaped components 200. The first wheel assembly 300 may consist only of a first wheel body 310, which is directly sleeved on the fixed shaft 100 to allow rotation relative to it. Alternatively, the first wheel assembly 300, in addition to the first wheel body 310, may also include a first bearing 320, with the first wheel body 310 sleeved on the fixed shaft 100 via the first bearing 320, thereby reducing friction when the first wheel body 310 rotates relative to the fixed shaft 100. Furthermore, the first wheel assembly 300, in addition to the first wheel body 310 and the first bearing 320, may also include a limiting member fixed to the first wheel body 310, which limits the first bearing 320 axially.

[0059] In addition to rotating relative to the fixed shaft 100, the first wheel assembly 300 can also move axially relative to the fixed shaft 100. To enable the first wheel assembly 300 to rotate relative to the fixed shaft 100, the friction between the electrode and the multiple arc-shaped members 200 can cause the roller 20 formed by the multiple arc-shaped members 200 to rotate, thereby driving the first wheel assembly 300 to rotate via the arc-shaped members 200; alternatively, a driving device can be provided to drive the first wheel assembly 300 to rotate actively, such as a motor, gear assembly, linkage mechanism, or lead screw and nut assembly. Furthermore, the first wheel assembly 300 can also move axially relative to the fixed shaft 100, thereby driving one end of the arc-shaped member 200 connected to it to move axially, thus changing the radial dimension of the first end 201 of the arc-shaped member 200 and its vicinity, thereby better fitting the tightness of the electrode near the first end 201. To enable the first wheel assembly 300 to move axially relative to the fixed shaft 100, the first wheel assembly 300 can be driven by a lead screw and nut assembly, or by a gear and rack assembly, cylinder, or other similar device. Alternatively, in other examples, in addition to being able to rotate relative to the fixed shaft 100, the first wheel assembly 300 can also be equipped with additional driving components to drive the radial dimension of the first end 201 of the arc-shaped member 200. For example, the first wheel assembly 300 can be equipped with a slider assembly, a connecting rod assembly, or a chuck, etc., to achieve the effect of changing the radial dimension of the first end 201 of the arc-shaped member 200 and its vicinity.

[0060] The second wheel assembly 500 refers to a disc assembly used to connect with the second ends 202 of multiple arc-shaped members 200. Specifically, in one example, the second ends 202 of the arc-shaped members 200 do not move axially or radially, the first ends 201 of the arc-shaped members 200 can swing radially, and the second ends 202 can serve as the fulcrum for the radial swing of the first ends 201. Then, the second wheel assembly 500 and the second ends 202 of the arc-shaped members 200 can be fixedly connected. Thus, when the first ends 201 of the arc-shaped members 200 can use the second ends 202 of the arc-shaped members 200 as a fulcrum to swing in the radial direction along the fixed axis 100, the arc-shaped members 200 are similar to the structure of an elastic arm. Alternatively, the second end 202 can be rotatably connected to the second wheel assembly 500. When the first end 201 of the arc-shaped member 200 can still use the second end 202 of the arc-shaped member 200 as a fulcrum and swing in the radial direction of the fixed shaft 100, the second end 202 of the arc-shaped member 200 can rotate relative to the second wheel assembly 500 with the swing of the first end 201, thereby reducing the risk of deformation of the second end 202. In another example, the second wheel assembly 500 can also push the second end 202 of the arc-shaped member 200 to move axially along the fixed shaft 100, thereby causing the first end 201 of the arc-shaped member 200 to also have at least a component of axial movement along the fixed shaft 100, which can swing radially through the wheel assembly, and when pushing the second end 202 of the arc-shaped member 200 to move axially along the fixed shaft 100, it drives the first end 201 of the arc-shaped member 200 to swing radially. Specifically, in order to drive the first end 201 of the arc-shaped component 200 to oscillate radially when the second end 202 of the arc-shaped component 200 moves axially, the first end 201 of the arc-shaped component 200 can be connected to the first wheel assembly 300 via a transmission component such as a slider or a gear and rack assembly. The second wheel assembly 500 can move axially along the fixed shaft 100 together with the second end 202 of the arc-shaped component 200, or a driving component can be provided on the second wheel assembly 500 to drive the second end 202 of the arc-shaped component 200 to move axially along the fixed shaft 100.

[0061] The drive assembly 400 is a component that is driven by the first wheel assembly 300 or the second wheel assembly 500, and enables the arc-shaped member 200 to expand or contract radially. When the drive assembly 400 is driven by the first wheel assembly 300, it can be mounted on the first wheel assembly 300 and directly drive the arc-shaped member 200 to expand or contract radially. Alternatively, the drive assembly 400 can be driven by the first wheel assembly 300 and drive it to move axially along the fixed shaft 100, thereby driving the arc-shaped member 200 to expand or contract radially, thus changing the radial dimension of the first end 201 and its vicinity of the arc-shaped member 200. In one example, when the drive assembly 400 drives the first wheel assembly 300 to move axially along the fixed shaft 100, the drive assembly 400 can specifically be a cylinder, linear motor, etc., that directly provides linear motion, and the cylinder or linear motor can be directly connected to the first wheel assembly 300. In another example, the drive assembly 400 can be a component that converts rotary motion into linear motion. For example, the drive assembly 400 includes a motor and a linkage-slider mechanism, with the linkage-slider mechanism being driven by the motor, and the first wheel assembly 300 being connected to the slider in the linkage-slider mechanism; or the drive assembly 400 can also include a gear and rack assembly, with the gear meshing with the rack, and the first wheel assembly 300 being connected to the rack, wherein the gear can be sleeved on the fixed shaft 100 or can be set independently of the fixed shaft 100, that is, the two are not connected; or the drive assembly 400 can include a lead screw and nut assembly, etc. In the axial motion state, the first wheel assembly 300 drives the first end 201 to move radially along the fixed shaft 100. This means that the axial motion of the first wheel assembly 300 is converted into the radial motion of the first end 201 of the arc-shaped member 200. This can be achieved through a combination of two sets of bevel gears and racks: the first wheel assembly 300 is connected to a rack that meshes with a bevel gear; the first end 201 of the arc-shaped member 200 is connected to another rack that meshes with another bevel gear, and the two bevel gears mesh with each other with their axes perpendicular. Alternatively, a slanted slider structure can be used to drive the first wheel assembly 300 and the first end 201 of the arc-shaped member 200, thereby achieving the effect of converting the axial motion of the first wheel assembly 300 into the radial motion of the first end 201 of the arc-shaped member 200.By driving the drive assembly 400 to the first wheel assembly 300 and driving the first wheel assembly 300 to move axially, and driving the first end 201 of the first wheel assembly 300 to move radially along the fixed shaft 100 during the axial movement, the distance between the first end 201 of the arc-shaped member 200 and the axis of the fixed shaft 100 can be changed during the axial movement of the first wheel assembly 300. This allows for unilateral adjustment of the radial dimension of the roller 20 near the first wheel assembly 300 according to the tightness of the electrode sheet via the adjusting member, thereby achieving a consistent tightness on both sides of the electrode sheet. It should be noted that one end of each of the multiple arc-shaped members 200 is driven to the first wheel assembly 300 so that during radial movement along the fixed shaft 100, the multiple arc-shaped members 200 can be in a state of mutual convergence or separation. When the multiple arc-shaped members 200 are in the state of mutual convergence, each pair of adjacent arc-shaped members 200 can be either in contact or have a gap.

[0062] When the drive assembly 400 is connected to the second wheel assembly 500, the drive assembly 400 can drive the second wheel assembly 500 to move axially on the fixed shaft 100, thereby driving the second end 202 of the arc-shaped member 200 to move axially on the fixed shaft 100. Driven by the axial movement of the second end 202 of the arc-shaped member 200, the first end 201 of the arc-shaped member 200 moves radially. Specifically, in order to drive the first end 201 of the arc-shaped member 200 to swing radially when the second end 202 of the arc-shaped member 200 moves axially, the first end 201 of the arc-shaped member 200 can be connected to the first wheel assembly 300 via a transmission assembly such as a slider or a gear and rack assembly. The second wheel assembly 500 can move together with the second end 202 of the arc-shaped member 200 in the axial direction of the fixed shaft 100, or a driving member can be provided on the second wheel assembly 500 to drive the second end 202 of the arc-shaped member 200 to move in the axial direction of the fixed shaft 100.

[0063] It should be noted that the structures of the first wheel assembly 300 and the second wheel assembly 500 in this invention are interchangeable. That is, the first wheel assembly 300 can drive the first end 201 of the arc-shaped member 200 to expand or contract radially; or in another example, the second wheel assembly 500 can also drive the second end 202 of the arc-shaped member 200 to expand or contract radially. In other words, it is not limited to the schemes disclosed in the text description and accompanying drawings of the above embodiments of this invention. Any scheme that enables the driving assembly 400 to expand or contract radially by driving one of the wheel assemblies is within the protection scope of this invention.

[0064] The technical solution of this invention arranges multiple arc-shaped components 200 around a fixed shaft 100, allowing the electrode sheet to be supported on these multiple arc-shaped components 200, and achieving the effect of conveying the electrode sheet by the arc-shaped components 200 as they rotate around the fixed shaft 100. A first wheel assembly 300 is driven to a first end 201, and a second end 202 is connected to a second wheel assembly 500, enabling both the first and second wheel assemblies 300 to rotate together with the multiple arc-shaped components 200. A drive assembly 400 is driven to the wheel assembly and causes the arc-shaped components 200 to expand or contract radially, thereby changing the radial dimension of the roller 20 formed by the first ends 201 of the multiple arc-shaped components 200. This radial dimension adapts to the tightness of the electrode sheet at this location, ensuring that the support tightness of the adjusting member for the electrode sheet near the first end 201 is consistent with the support tightness of the electrode sheet near the second end 202 of the arc-shaped component 200.

[0065] In one embodiment of the present invention, the drive assembly 400 is connected to the first wheel assembly 300 in a transmission connection and drives the first wheel assembly 300 to move axially along the fixed shaft 100, so that the first end 201 can move radially with the second end 202 as the fulcrum.

[0066] By driving the first wheel assembly 300 to move axially through the drive assembly 400, and driving the first end 201 to move radially along the fixed shaft 100 with the second end 202 as the fulcrum while the first wheel assembly 300 is moving axially, the space required for the drive assembly 400 between the first wheel assembly 300 and the fixed shaft 100, or between the arc-shaped member 200 and the fixed shaft 100, can be reduced. At the same time, this arrangement also allows the axial movement of one first wheel assembly 300 to drive all the multiple arc-shaped members 200 connected to it to move radially along the fixed shaft 100 simultaneously, improving drive efficiency and drive cost, and reducing the need to drive each arc-shaped member 200 individually.

[0067] By moving the first end 201 radially along the fixed shaft 100 with the second end 202 as the fulcrum, the multiple first ends 201 expand away from the fixed shaft 100 or converge towards the fixed shaft 100. This achieves the effect of adjusting the tightness of the support of the two ends of the roller 20 on the electrode sheet in a consistent manner by adjusting the radial dimension of the roller 20 on one side, thereby improving the adjustment efficiency and accuracy.

[0068] Please refer to the reference. Figures 1 to 3 In one embodiment of the present invention, one of the first end 201 and the first wheel assembly 300 is provided with an inclined slide groove 210, and the other of the first end 201 and the first wheel assembly 300 is provided with a first pin 312, which is slidably disposed in the inclined slide groove 210.

[0069] The inclined groove 210 refers to a groove that extends in the axial direction of the fixed shaft 100 and is inclined in the radial direction of the fixed shaft 100. Specifically, the first end 201 is provided with the inclined groove 210, and the first wheel assembly 300 is provided with the first pin 312. Alternatively, the first end 201 is provided with the first pin 312, and the first wheel assembly 300 is provided with the inclined groove 210. Taking the inclined groove 210 provided on the first end 201 as an example, the end of the inclined groove 210 near the second wheel assembly 500 can be inclined towards the fixed shaft 100. When the first wheel assembly 300 and the first pin 312 provided on the first wheel assembly 300 move towards the second wheel assembly 500, the first end 201 of the arc-shaped member 200 moves towards the fixed shaft 100. At this time, the first ends 201 of multiple arc-shaped members 200 converge with each other, thereby reducing the outer diameter of the end of the roller 20 away from the second wheel assembly 500. Alternatively, the end of the inclined slide 210 near the second wheel assembly 500 can be tilted away from the fixed shaft 100. When the first wheel assembly 300 and the first pin 312 on the first wheel assembly 300 move towards the second wheel assembly 500, the first end 201 of the arc-shaped member 200 moves away from the fixed shaft 100. At this time, the first ends 201 of the multiple arc-shaped members 200 separate from each other, thereby increasing the outer diameter of the end of the roller 20 away from the second wheel assembly 500.

[0070] The first pin 312 refers to a cylinder that is inserted into the inclined slide groove 210 and can slide within the inclined slide groove 210. Taking the first pin 312 being provided on the first wheel assembly 300 as an example, the first pin 312 can be inserted into the first wheel assembly 300, or it can be integrally formed with the first wheel assembly 300 by integral molding, or it can be welded to the first wheel assembly 300 by welding.

[0071] By providing a slanted groove 210 on one of the first end 201 and the first wheel assembly 300, and a first pin 312 on the other end, with the first pin 312 slidably disposed within the slanted groove 210, when the first wheel assembly 300 moves axially along the fixed shaft 100, the first pin 312 slides within the slanted groove 210. This, through the abutting action of the first pin 312 against the groove wall of the slanted groove 210, drives the arc-shaped member 200 to move radially away from or towards the fixed shaft 100. Furthermore, by employing a structure where the first pin 312 slides within the slanted groove 210, the need for a sliding block to connect the arc-shaped member 200 and the first wheel assembly 300 is reduced, thus simplifying the transmission structure and reducing the space occupied by the transmission structure.

[0072] Please refer to the reference. Figures 1 to 3 In one embodiment of the present invention, a plurality of first slots 311 are provided on the first wheel assembly 300. The plurality of first slots 311 are arranged along the circumference of the first wheel assembly 300, and the first slot 311 has a first opening facing the second wheel assembly 500. The first end 201 is inserted into the first slot 311; the first pin 312 is provided on the side wall of the first slot 311, and the inclined slide 210 is provided on the first end 201.

[0073] The first slot 311 refers to the second slot 511 into which the first end 201 of the arc-shaped member 200 is inserted. The shape of the second slot 511 can be elliptical, rectangular or other shapes.

[0074] By having the first slot 311 have a first opening facing the second wheel assembly 500, and the first end 201 of the arc-shaped member 200 is located within the second slot 511, the space occupied by the adjusting member in the radial direction of the fixed shaft 100 can be reduced. By placing the first pin 312 on the side wall of the first slot 311 and the inclined slide 210 on the first end 201, a good protective effect can be achieved for the first pin 312 and the inclined slide 210, reducing the risk that dust entering the inclined slide 210 may prevent the first end 201 of the arc-shaped member 200 from effectively moving in the radial direction of the fixed shaft 100 when the first wheel assembly 300 moves axially.

[0075] Please refer to the reference. Figures 1 to 2 In one embodiment of the present invention, the first wheel assembly 300 includes a first wheel body 310 and a first bearing 320. The first wheel body 310 is convexly connected to the first end 201. The first bearing 320 is sleeved outside the fixed shaft 100; the first wheel body 310 is sleeved outside the first outer ring 322 of the first bearing 320, and the drive assembly 400 is convexly connected to the first inner ring 321 of the first bearing 320, and drives the first bearing 320 to move axially.

[0076] The first wheel body 310 refers to a disc-shaped component with a sleeve hole in the center. The sleeve hole of the first wheel body 310 is used for the fixed shaft 100 to pass through. When the first wheel body 310 is connected to the first end 201 in a transmission manner, the method of connecting the first wheel assembly 300 and the first end 201 in a transmission manner described above can be used, which will not be described in detail here.

[0077] The first bearing 320 refers to a rolling bearing that is sleeved on the fixed shaft 100 and located within the sleeve hole of the first wheel body 310, such as a self-aligning ball bearing, self-aligning roller bearing, tapered roller bearing, double-row deep groove ball bearing, thrust ball bearing, deep groove ball bearing, angular contact ball bearing, cylindrical roller bearing, needle roller bearing, etc. The first inner ring 321 refers to an annular component near the axis of the first bearing 320. The first outer ring 322 refers to an annular component that is sleeved on the outside of the first inner ring 321 and has rolling elements sandwiched between it and the first inner ring 321, thus allowing it to rotate relative to the first inner ring 321. The first bearing 320 has a first inner ring 321 and a first outer ring 322. The first inner ring 321 of the first bearing 320 is sleeved on the outside of the fixed shaft 100, and the first outer ring 322 of the first bearing 320 contacts the wall of the sleeve hole of the first wheel body 310. Thus, when the first wheel body 310 rotates, it drives the first outer ring 322 of the first bearing 320 to rotate, while the first inner ring 321 of the first bearing 320 remains stationary; or, when the first inner ring 321 of the first bearing 320 rotates, the first outer ring 322 of the first bearing 320 and the first wheel body 310 do not rotate.

[0078] By sleeved the first bearing 320 outside the fixed shaft 100 and the first wheel body 310 outside the first outer ring 322 of the first bearing 320, the first wheel body 310 and the first outer ring 322 of the first bearing 320 can rotate simultaneously, thereby reducing the frictional force when the first wheel body 310 rotates. By driving the drive assembly 400 to drive the first inner ring 321 of the first bearing 320 and driving the first bearing 320 to move axially, when the drive assembly 400 drives the first bearing 320 to move axially on the fixed shaft 100, the first bearing 320 can drive the first wheel body 310 to move axially on the fixed shaft 100, thereby ensuring that the first end 201 of the arc-shaped member 200 can move radially on the fixed shaft 100, thereby achieving the effect of adjusting the radial dimension of the end of the roller 20 close to the first wheel assembly 300. In addition, it is understandable that when the roller 20 supports the electrode to rotate under the friction of the electrode, the roller 20 can drive the first wheel disc body 310 and the first outer ring 322 of the bearing to rotate, while the first inner ring 321 of the bearing does not rotate, thus preventing the drive assembly 400 from rotating. This ensures that the drive assembly 400 has a good stability effect and reduces the risk that the rotation of the drive assembly 400 will affect the driving effect of the bearing.

[0079] Please refer to the reference. Figures 1 to 2 In one embodiment of the present invention, the drive assembly 400 includes a sleeve assembly 410 sleeved outside the fixed shaft 100, the sleeve assembly 410 being axially movable on the fixed shaft 100; the first inner ring 321 of the first bearing 320 is fixedly sleeved outside the sleeve assembly 410.

[0080] The sleeve assembly 410 refers to an assembly that can be fitted onto the fixed shaft 100. The sleeve assembly 410 may consist of only a straight sleeve fitted onto the fixed shaft 100, or it may further include a limiting ring disposed outside the straight sleeve, with the first inner rings 321 of a pair of first bearings 320 being axially limited. Specifically, the sleeve assembly 410 is used to fit onto the fixed shaft 100, therefore the sleeve assembly 410 has an inner hole that contacts the fixed shaft 100. The surface of this inner hole can be a smooth surface or it can be provided with internal threads. When the inner hole surface of the sleeve assembly 410 fitted onto the fixed shaft 100 is provided with internal threads, the outer surface of the fixed shaft 100 can correspondingly be provided with external threads.

[0081] The drive assembly 400 may consist only of the sleeve assembly 410. When the inner surface of the sleeve assembly 410 is smooth, the user can manually push the sleeve assembly 410; or when the inner surface of the sleeve assembly 410 has internal threads, the user can manually rotate the sleeve assembly 410 so that the sleeve assembly 410 can move axially along the fixed shaft 100. Alternatively, the drive assembly 400 may also include a drive motor. When the inner surface of the sleeve assembly 410 is smooth, the drive motor can push the sleeve assembly 410 so that the sleeve assembly 410 can move axially along the fixed shaft 100; or when the inner surface of the sleeve assembly 410 has internal threads, the drive motor drives the sleeve assembly 410 to rotate so that the sleeve assembly 410 can move axially along the fixed shaft 100.

[0082] By fixing the first inner ring 321 of the first bearing 320 to the outside of the sleeve assembly 410, the wear between the first bearing 320 and the fixed shaft 100 can be reduced, thereby ensuring that the first outer ring 322 of the first bearing 320 can rotate stably relative to the first inner ring 321, thus ensuring the stability of the rotation of the first wheel body 310 and the roller 20, and reducing the risk of the electrode sheet on the roller 20 shaking.

[0083] Please refer to the reference. Figures 1 to 2 Furthermore, the sleeve assembly 410 includes a threaded sleeve, and the fixed shaft 100 is provided with an external thread, with the threaded sleeve engaging with the external thread.

[0084] A threaded sleeve is a sleeve with an inner hole, the wall of which is provided with internal threads.

[0085] By setting an external thread on the fixed shaft 100 and threading the threaded sleeve with the external thread of the fixed shaft 100, the effect of rotating relative to the fixed shaft 100 and moving in its axial direction can be achieved by rotating the threaded sleeve. In this way, the threaded sleeve can drive the first inner ring 321 of the first bearing 320 to rotate relative to the fixed shaft 100 and move in the axial direction of the fixed shaft 100. This enables the first bearing 320 to drive the first wheel assembly 300 to move in the axial direction of the fixed shaft 100, so that the first end 201 of the arc-shaped member 200 moves in the radial direction of the fixed shaft 100, thereby increasing or decreasing the outer diameter of the end of the roller 20 close to the first wheel body 310.

[0086] Because of the first bearing 320, which is sleeved on the outside of the threaded sleeve and has a threaded engagement with the external thread of the fixed shaft 100, the rotation of the first outer ring 322 of the first bearing 320 and the first wheel body 310 with the roller 20 will not affect the threaded sleeve. That is, the threaded sleeve will not rotate with the rotation of the first outer ring 322 of the first bearing 320, nor will it easily move along the axial direction of the fixed shaft 100. Therefore, the risk of the threaded sleeve driving the first bearing 320 to move along the axial direction of the fixed shaft 100 can be avoided. This also avoids the risk of the outer diameter of the roller 20 changing at any time while the roller 20 is rotating, thus ensuring the stability of the roller 20 during rotation. Furthermore, it is understood that when the threaded sleeve rotates and moves in the axial direction of the fixed shaft 100, it only drives the first inner ring 321 of the first bearing 320 to rotate and move in the axial direction of the fixed shaft 100, while the first outer ring 322 of the first bearing 320 does not rotate but only moves in the axial direction of the fixed shaft 100. This causes the first wheel assembly 300 to move only in the axial direction of the fixed shaft 100, thereby causing the first end 201 of the arc-shaped member 200 to move only in the radial direction of the fixed shaft 100. This avoids the risk of torsion caused by the first end 201 of the arc-shaped member 200 rotating relative to the fixed shaft 100 while moving in the radial direction. Therefore, the stability of the roller 20 composed of multiple arc-shaped members 200 in expanding or contracting in the radial direction can be guaranteed. In other words, in this embodiment, the combination of the threaded sleeve and the first bearing 320 ensures that the rotation of the roller 20 does not affect the rotation of the threaded sleeve during rotation, thus preventing the size of the roller 20 in the radial direction from changing at any time; and it also ensures that the roller 20 does not experience torsion while changing its radial size.

[0087] Please refer to the reference. Figures 1 to 3 In one embodiment of the present invention, the sleeve assembly 410 is provided with a positioning hole, the axis of which is perpendicular to the axial direction of the sleeve assembly 410; the adjusting member also includes a positioning member 600, which passes through the positioning hole and is connected to the fixed shaft 100.

[0088] The positioning hole can be a through hole or a threaded hole. The positioning element 600 can be a pin, rivet, screw, or bolt, etc. For example, when the positioning hole is a through hole, the positioning element 600 can be a pin or rivet; when the positioning hole is a threaded hole, the positioning element 600 can be a screw or bolt, etc.

[0089] When the positioning element 600 is connected to the fixed shaft 100, it can be connected by passing through the fixed shaft 100 and locking it with a locking device, by abutting against the fixed shaft 100, or by threaded connection with the fixed shaft 100. For example, when the positioning element 600 is a bolt, multiple through holes spaced apart along the axial direction of the fixed shaft 100 can be provided on the fixed shaft 100. These through holes penetrate opposite sides of the fixed shaft 100 in the radial direction, allowing a bolt to pass through the positioning hole and one of the through holes, and then be locked to the bolt with a nut. This positions the sleeve assembly 410 on the fixed shaft 100, further reducing the risk of rotation and / or movement of the sleeve assembly 410 relative to the fixed shaft 100. Alternatively, when the positioning element 600 is a bolt, the bolt can abut against the outer circumferential surface of the fixed shaft 100 after passing through the positioning hole.

[0090] By providing a positioning hole on the sleeve assembly 410, with the axis of the positioning hole perpendicular to the axial direction of the sleeve assembly 410, and the positioning member 600 passing through the positioning hole and connected to the fixed shaft 100, the sleeve assembly 410 can be positioned on the fixed shaft 100, thereby reducing the risk of the sleeve assembly 410 rotating and / or moving relative to the fixed shaft 100, and thus ensuring that the roller 20 can rotate stably under the friction of the electrode sheet.

[0091] Understandably, when a user needs to move or rotate the sleeve assembly 410 axially on the fixed shaft 100, the positioning member 600 can be dislodged from the positioning hole first, and then the sleeve assembly 410 can be driven to move or rotate on the fixed shaft 100.

[0092] Please refer to the reference. Figures 1 to 3 Furthermore, the positioning hole is a threaded hole; the positioning element 600 is a positioning bolt, which is threadedly connected to the threaded hole, and the positioning bolt radially abuts against the fixed shaft 100.

[0093] This design reduces the need for drilling holes in the fixed shaft 100, minimizing the weakening effect on its strength. Furthermore, this design allows the positioning element 600 to be threaded into the positioning hole, reducing the risk of the positioning element 600 easily falling out of the hole, resulting in more secure positioning and allowing for flexible adjustment of the supporting force against the fixed shaft 100.

[0094] Please refer to the reference. Figures 1 to 2In one embodiment of the present invention, the sleeve assembly 410 includes a sleeve body 411, a first limiting part 412, and a second limiting part 413. The sleeve body 411 is sleeved outside the fixed shaft 100, and the first bearing 320 is sleeved outside the sleeve body 411. The first limiting part 412 is fixedly disposed on the sleeve body 411 and is disposed on one side of the first bearing 320 in the axial direction. The second limiting part 413 is fixedly disposed on the sleeve body 411 and is disposed on the other side of the first bearing 320 in the axial direction.

[0095] The sleeve body 411 refers to the sleeve component sleeved outside the fixed shaft 100. The first bearing 320 is sleeved outside the sleeve body 411, so that when the sleeve body 411 rotates, it drives the first inner ring 321 of the first bearing 320 to rotate; when the sleeve body 411 moves along the axial direction of the fixed shaft 100, it drives the first inner ring 321 of the first bearing 320 to move with the sleeve body 411. It can be understood that in order to achieve the same movement state between the first inner ring 321 of the first bearing 320 and the sleeve body 411, the sleeve body 411 and the first bearing 320 can be interference-fitted or transition-fitted.

[0096] The first limiting part 412 refers to a component fixedly mounted on the sleeve body 411. The first limiting part 412 can be annular or a plurality of limiting posts arranged in a circular array along the circumference of the sleeve body 411. The first limiting part 412 can be integral with the sleeve body 411, connected to the sleeve body 411 by a snap-fit, or fitted with the sleeve body 411 by an interference fit. The first limiting part 412 is located on one side of the first bearing 320 in the axial direction, for example, on the side of the first bearing 320 facing the roller 20, or on the side of the first bearing 320 away from the roller 20. The first limiting part 412 can limit only the first inner ring 321 of the first bearing 320, or the first limiting part 412 can limit both the first inner ring 321 and the first outer ring 322 of the first bearing 320.

[0097] The second limiting part 413 refers to a component fixedly mounted on the sleeve body 411 and located on the side of the first bearing 320 away from the first limiting part 412 to limit the axial movement of the first bearing 320. For example, when the first limiting part 412 is located on the side of the first bearing 320 facing the roller 20, the second limiting part 413 is located on the side of the first bearing 320 away from the roller 20; when the first limiting part 412 is located on the side of the first bearing 320 away from the roller 20, the second limiting part 413 is located on the side of the first bearing 320 closer to the roller 20. The second limiting part 413 can be annular or multiple limiting posts arranged in a circular array along the circumference of the sleeve body 411. The second limiting part 413 can be integral with the sleeve body 411, connected to the sleeve body 411 by snap-fit, or fitted with the sleeve body 411 by interference fit, etc. The second limiting part 413 may limit only the first inner ring 321 of the first bearing 320, or the second limiting part 413 may limit both the first inner ring 321 and the first outer ring 322 of the first bearing 320.

[0098] By fixing a first limiting part 412 and a second limiting part 413 on the sleeve body 411, and the first limiting part 412 and the second limiting part 413 are respectively provided on opposite sides of the first bearing 320 in the axial direction, the risk of the first bearing 320 sliding on the sleeve body 411 in the axial direction can be reduced, thereby improving the stability of the first inner ring 321 of the first bearing 320 moving synchronously with the sleeve body 411, so that the sleeve body 411 can drive the first bearing 320 to move synchronously when it reciprocates in the axial direction.

[0099] Please refer to the reference. Figures 1 to 2 In one embodiment of the present invention, the first limiting part 412 and the second limiting part 413 both abut against the first inner ring 321 of the first bearing 320.

[0100] By having both the first limiting part 412 and the second limiting part 413 abut against the first inner ring 321 of the first bearing 320, the movement state of the first inner ring 321 of the first bearing 320 can be kept consistent with the movement state of the main body. Furthermore, this arrangement reduces the interference of the first limiting part 412 and the second limiting part 413 on the movement of the first outer ring 322 of the first bearing 320. Therefore, when the first outer ring 322 of the first bearing 320, the first wheel assembly 300, and the roller 20 rotate, the first limiting part 412 and the second limiting part 413 will not affect the rotation of the first outer ring 322 of the first bearing 320, the first wheel assembly 300, and the roller 20, thereby reducing the frictional force when the first outer ring 322 of the first bearing 320, the first wheel assembly 300, and the roller 20 rotate.

[0101] Please refer to the reference. Figures 1 to 2In one embodiment of the present invention, the first wheel body 310 is provided with a third limiting part 330 and a fourth limiting part 340, which are respectively provided on opposite sides of the first outer ring 322 of the first bearing 320.

[0102] The third limiting part 330 refers to a component fixedly mounted on the first wheel body 310 and capable of limiting one side of the first outer ring 322 of the first bearing 320. This third limiting part 330 can be a limiting ring arranged circumferentially on the first wheel body 310, or it can be a plurality of limiting posts arranged in a circular array along the circumference of the first wheel body 310, with the limiting posts protruding from the outer circumferential surface of the first wheel body 310. The third limiting part 330 can be integrally formed with the first wheel body 310, connected to the first wheel body 310 by a snap-fit, or fitted with the first wheel body 310 by an interference fit, etc. The third limiting part 330 is located on one side of the first outer ring 322 of the first bearing 320, for example, on the side of the first outer ring 322 of the first bearing 320 facing the roller 20, or on the side of the first outer ring 322 of the first bearing 320 away from the roller 20.

[0103] The fourth limiting part 340 is a component that is fixedly mounted on the first wheel body 310 and located on the side of the first outer ring 322 of the first bearing 320 away from the third limiting part 330, so as to limit the first outer ring 322 of the first bearing 320 axially. For example, when the third limiting part 330 is located on the side of the first outer ring 322 of the first bearing 320 facing the roller 20, the fourth limiting part 340 is located on the side of the first outer ring 322 of the first bearing 320 away from the roller 20; when the third limiting part 330 is located on the side of the first outer ring 322 of the first bearing 320 away from the roller 20, the fourth limiting part 340 is located on the side of the first outer ring 322 of the first bearing 320 close to the roller 20. The fourth limiting part 340 can be a limiting ring arranged circumferentially on the first wheel body 310, or the fourth limiting part 340 can be a plurality of limiting posts arranged in a circular array along the circumference of the first wheel body 310, and the limiting posts protrude from the outer circumferential surface of the first wheel body 310. The fourth limiting part 340 can be integral with the first wheel body 310, or it can be connected to the first wheel body 310 by means of snap-fit ​​or screw connection, or it can be fitted with the first wheel body 310 by interference fit, etc.

[0104] By connecting the third limiting part 330 and the fourth limiting part 340 to the first wheel body 310 and respectively disposed on opposite sides of the first outer ring 322 of the first bearing 320, the opposite sides of the first outer ring 322 of the first bearing 320 can be stopped by the third limiting part 330 and the fourth limiting part 340. Therefore, when the first bearing 320 moves along its axial direction, the first bearing 320 can drive the first wheel body 310 to move synchronously, avoiding the risk that the first wheel body 310 cannot move with the first bearing 320 when it moves in the axial direction.

[0105] Please refer to the reference. Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the second wheel assembly 500 includes a second wheel body 510 and a second bearing 520. A second end 202 is connected to the second wheel body 510. The second bearing 520 is fixedly sleeved outside the fixed shaft 100, and the second wheel body 510 is sleeved outside the second bearing 520.

[0106] The second wheel body 510 refers to a disc-shaped component that can be fitted over the fixed shaft 100 and is located at the end of the roller 20 away from the first wheel assembly 300. When the second wheel body 510 is connected to the second end 202, it can be a fixed connection or a rotatable connection.

[0107] The second bearing 520 refers to a rolling bearing that is sleeved outside the fixed shaft 100 and located inside the second wheel body 510, such as a self-aligning ball bearing, a self-aligning roller bearing, a tapered roller bearing, a double-row deep groove ball bearing, a thrust ball bearing, a deep groove ball bearing, an angular contact ball bearing, a cylindrical roller bearing, a needle roller bearing, etc.

[0108] By fixing the second bearing 520 outside the fixed shaft 100 and the second wheel body 510 outside the second bearing 520, the frictional force of the second wheel body 510 during rotation is reduced, and the second wheel body 510 is prevented from moving axially on the fixed shaft 100. This ensures the stability of the arc-shaped part 200 connected to the second wheel assembly 500 and reduces the risk of the arc-shaped part 200 expanding outward or contracting inward under the drive of the axial movement of the second wheel assembly 500. In other words, it ensures the stability of the roller 20 near the second wheel assembly 500, making it easier for the user to adjust the radial dimension of the roller 20 only on one side near the first wheel assembly 300, thus improving adjustment efficiency and accuracy.

[0109] Please refer to the reference. Figure 1 , Figure 2 and Figure 4In one embodiment of the present invention, the second end 202 is rotatably connected to the second wheel body 510, and the rotation axis of the second end 202 extends along a first direction, which is perpendicular to both the axial direction and the radial direction of the fixed shaft 100.

[0110] To achieve a rotatable connection between the second end 202 and the second wheel body 510, and to ensure that the axis of rotation of the second end 202 extends along the first direction, in one example, the second end 202 of the arc-shaped member 200 is provided with a shaft hole 220, and the second wheel body 510 is provided with a rotating shaft 512, the axis of which extends along the first direction and is rotatably disposed within the shaft hole 220. Alternatively, in another example, the second end 202 of the arc-shaped member 200 is provided with a rotating shaft 512, the axis of which extends along the first direction, and the second wheel body 510 is provided with a shaft hole 220, the rotating shaft 512 being rotatably disposed within the shaft hole 220.

[0111] With this configuration, when the first end 201 of the arc-shaped component 200 moves in the radial direction of the fixed shaft 100 with the second end 202 of the arc-shaped component 200 as the fulcrum, the second end 202 of the arc-shaped component 200 can rotate with the swing of the first end 201, thereby reducing the risk of the second end 202 of the arc-shaped component 200 being forcibly bent and deformed.

[0112] Please refer to the reference. Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the second wheel body 510 is provided with a plurality of second slots 511, which are spaced apart circumferentially; the second slots 511 have a second opening facing the first wheel assembly 300, and the second end 202 of the arc-shaped member 200 is rotatably disposed in the second slot 511.

[0113] The second slot 511 refers to the second slot 511 into which the second end 202 of the arc-shaped member 200 is inserted. The shape of the second slot 511 can be elliptical, rectangular or other shapes.

[0114] By making the second slot 511 have a second opening facing the first wheel assembly 300, and the second end 202 of the arc-shaped member 200 is rotatably disposed in the second slot 511, the space occupied by the adjusting member in the radial direction of the fixed shaft 100 can be reduced, and a good protection effect on the second end 202 of the arc-shaped member 200 can be achieved.

[0115] In another example, multiple connecting parts may be provided at intervals on the outer peripheral surface of the second wheel body 510. One of the connecting parts and the second end 202 of the arc-shaped member 200 is provided with a shaft hole 220, and the other is provided with a rotating shaft 512. The axis of the rotating shaft 512 extends along the first direction.

[0116] Of course, in order to reduce the risk of wear on the rotating shaft 512, a third bearing can be fitted on the outside of the rotating shaft 512, and the third bearing is installed in the shaft hole 220.

[0117] Furthermore, such as Figure 2 As shown, in order to limit the overall positioning of the second wheel body 510 and the second bearing 520, the adjusting component may also include a fixing ring 700. The fixing ring 700 is fixedly sleeved outside the fixing shaft 100 and located on the side of the second bearing 520 away from the first wheel assembly 300, and the fixing ring 700 abuts against the second inner ring of the second bearing 520.

[0118] The second inner ring refers to the annular component in the second bearing 520 that is close to the fixed shaft 100.

[0119] The fixed ring 700 refers to the ring-shaped component that is fixedly sleeved outside the fixed shaft 100. It can be a plate-shaped annular ring or a stepped annular ring.

[0120] By fixing the retaining ring 700 around the fixed shaft 100 and positioning it on the side of the second bearing 520 away from the first wheel assembly 300, and by having the retaining ring 700 abut against the second inner ring of the second bearing 520, the retaining ring 700 can limit the axial movement of the second bearing 520, thereby reducing the risk of axial movement of the second bearing 520. Furthermore, by having the retaining ring 700 abut against the second inner ring of the second bearing 520, the movement of the second outer ring of the second bearing 520 with the rotation of the second wheel body 510 can be prevented. This allows the second bearing 520 and the second wheel body 510 to rotate around the fixed shaft 100 while also reducing the risk of axial movement of the second wheel assembly 500.

[0121] Furthermore, such as Figure 2 As shown, when the second wheel body 510 rotates only around the fixed shaft 100 and cannot rotate along the axial direction of the fixed shaft 100, in order to ensure the stability of the relative position between the second wheel body 510 and the second bearing 520, the second wheel body 510 in this embodiment is also connected with a fifth limiting part 530 and a sixth limiting part 540. The fifth limiting part 530 and the sixth limiting part 540 are respectively provided on opposite sides of the second outer ring of the second bearing 520.

[0122] The second outer ring refers to the annular component that is fitted outside the second inner ring and has a rolling element sandwiched between them, so that the second outer ring can rotate relative to the second inner ring.

[0123] The fifth limiting part 530 refers to a component fixedly mounted on the second wheel body 510 and capable of limiting one side of the second outer ring of the second bearing 520. This fifth limiting part 530 can be a limiting ring arranged circumferentially on the second wheel body 510, or it can be a plurality of limiting posts arranged in a circular array along the circumference of the second wheel body 510, with each limiting post protruding from the outer circumferential surface of the second wheel body 510. The fifth limiting part 530 can be integrally formed with the second wheel body 510, connected to the second wheel body 510 by a snap-fit, or fitted with the second wheel body 510 by an interference fit. The fifth limiting part 530 is located on one side of the second bearing 520, for example, on the side of the second outer ring of the second bearing 520 facing the roller 20, or on the side of the second outer ring of the second bearing 520 away from the roller 20.

[0124] The sixth limiting part 540 refers to a component fixedly disposed on the second wheel body 510 and located on the side of the second outer ring of the second bearing 520 away from the fifth limiting part 530, to axially limit the second outer ring of the second bearing 520. For example, when the fifth limiting part 530 is located on the side of the second outer ring of the second bearing 520 facing the roller 20, the sixth limiting part 540 is located on the side of the second outer ring of the second bearing 520 away from the roller 20; when the fifth limiting part 530 is located on the side of the second outer ring of the second bearing 520 away from the roller 20, the sixth limiting part 540 is located on the side of the second outer ring of the second bearing 520 closer to the roller 20. The sixth limiting part 540 can be a limiting ring disposed circumferentially on the second wheel body 510, or the sixth limiting part 540 can be a plurality of limiting posts disposed in a circular array along the circumferential direction of the second wheel body 510, and the limiting posts protrude from the outer circumferential surface of the second wheel body 510. The sixth limiting part 540 may be integral with the second wheel body 510, or it may be connected to the second wheel body 510 by means of snap-fit ​​or screw connection, or it may be fitted with the second wheel body 510 by interference fit.

[0125] By connecting the fifth limiting part 530 and the sixth limiting part 540 to the second wheel body 510 and respectively providing them on opposite sides of the second outer ring of the second bearing 520, the opposite sides of the second outer ring of the second bearing 520 can be stopped by the fifth limiting part 530 and the sixth limiting part 540. Therefore, the relative stability between the second bearing 520 and the second wheel body 510 can be guaranteed, and the risk of the second bearing 520 moving relative to the second wheel body 510 in the axial direction can be avoided.
