[0050] As described in the background art, a rewinder is a device used to wind materials such as continuously produced films, papers, and metal foils into a roll shape, and is widely used in fields such as printing, packaging, and lithium battery manufacturing. The rewinder winds the material evenly on the surface of the sleeve through an internal mechanical structure to form a neat finished coil, which is convenient for subsequent storage, transportation, or processing.

[0051] In the related art, the rewinder mainly includes a main shaft, a motor, a gland, and a sleeve. Among them, the main shaft is driven by the motor to rotate, the gland is fixed on the main shaft by bolts, and a groove matching the end of the sleeve is machined on the inner side of the gland. The sleeve is fixed by embedding both ends of the sleeve into the gland groove. During operation, the material is wound around the surface of the sleeve, and the main shaft drives the sleeve to rotate to complete the winding process.

[0052] However, when it is necessary to replace sleeves of different diameters, it is necessary to customize and replace the matching glands for each specification of the sleeve, resulting in high production costs and greatly reducing production efficiency.

[0053] To solve the above problems, an embodiment of the present application provides a winding machine, which includes at least two support members; two tapered disks, with at least one support member correspondingly arranged on each tapered disk, and at least one assembly portion arranged on the circumferential side of each tapered disk; a variable-diameter shaft, both ends of the variable-diameter shaft are connected to the middle parts of the two tapered disks respectively, and an adjusting member is arranged on the variable-diameter shaft, and the adjusting member is configured to drive the diameter of the variable-diameter shaft to increase or decrease; a plurality of sleeves, correspondingly sleeved on the variable-diameter shaft or correspondingly arranged on the assembly portions; a first driving member, connected to one of the tapered disks, and the first driving member is configured to drive the tapered disk to rotate so as to drive the winding member on the sleeve to wind. By driving the diameter of the variable-diameter shaft to increase or decrease through the adjusting member on the variable-diameter shaft, sleeves with different diameters can be adapted. By arranging the assembly portions on the circumferential side of the tapered disks, the sleeves can still be fixed through the assembly portions when the adjustment range of the variable-diameter shaft is insufficient, thereby expanding the range of adaptable sleeve sizes.

[0054] The following uses specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0055] Figure 1 It is a schematic structural diagram of the winding machine provided by the embodiment of the present application, Figure 2 is Figure 1 a schematic structural diagram of the variable-diameter shaft in Figure 3 is Figure 1 a schematic connection diagram of the variable-diameter shaft and the tapered disk in

[0056] Please refer to Figure 1 . This embodiment provides a winding machine, which includes at least two support members 100; two tapered disks 200, with at least one support member 100 correspondingly arranged on each tapered disk 200, and at least one assembly portion 201 arranged on the circumferential side of each tapered disk 200; a variable-diameter shaft 300, both ends of the variable-diameter shaft 300 are connected to the middle parts of the two tapered disks 200 respectively, and an adjusting member is arranged on the variable-diameter shaft 300, and the adjusting member is configured to drive the diameter of the variable-diameter shaft 300 to increase or decrease; a plurality of sleeves 400, correspondingly sleeved on the variable-diameter shaft 300 or correspondingly arranged on the assembly portions 201; a first driving member 500, connected to one of the tapered disks 200, and the first driving member 500 is configured to drive the tapered disk 200 to rotate so as to drive the winding member on the sleeve 400 to wind.

[0057] Specifically, in this embodiment, the number of support members 100 is two, and the two support members 100 are arranged in parallel and opposite to support the entire winding machine. Among them, the support members 100 can be arranged on the base or directly fixed to the foundation through anchor bolts, and this embodiment does not impose any restrictions on this.

[0058] In other embodiments, the number of the supporting members 100 can also be adaptively increased to improve the stability of the support for the tapered disks 200. In this regard, this embodiment does not impose any restrictions.

[0059] Specifically, in this embodiment, the two tapered disks 200 are respectively arranged on the two supporting members 100 and are coaxially and oppositely arranged, so as to ensure the centering accuracy when the sleeve 400 is installed on the tapered disk 200 and the dynamic balance performance during rotation.

[0060] Among them, the tapered disk 200 can be fixed on the bearing seat of the supporting member 100 by means of flange connection, which is convenient for disassembly and maintenance, or can be connected to the supporting member 100 by other means. In this regard, this embodiment does not impose any restrictions.

[0061] In this embodiment, the tapered disk 200 has a disk-shaped structure, and its axis is perpendicular to the mounting surface of the supporting member 100. At least one assembly portion 201 is formed on the tapered disk 200, and the assembly portion 201 is arranged along the circumferential direction of the tapered disk 200, so as to provide a mounting position for the sleeve 400. Specifically, when the sleeve 400 needs to be installed on the tapered disk 200, the two ends of the sleeve 400 can be directly snapped into the assembly portion 201, so as to realize the quick installation and positioning of the sleeve 400.

[0062] Meanwhile, it should be noted that the position and size of the assembly portion 201 can be adaptively selected according to actual requirements, and the assembly portion 201 can be directly adapted to the common sizes of the sleeves 400. In this regard, this embodiment does not impose any restrictions.

[0063] In addition, the number of the assembly portions 201 can be multiple, and the multiple assembly portions 201 are arranged along the axial direction of the tapered disk 200. Each assembly portion 201 corresponds to a diameter of the sleeve 400, and different assembly portions 201 are selected to adapt to sleeves 400 with different diameters.

[0064] Specifically, in this embodiment, the rewinder further includes a variable-diameter shaft 300. The two ends of the variable-diameter shaft 300 are respectively fixedly connected to the two tapered disks 200, and the adjusting member is used to adjust the diameter of the variable-diameter shaft 300 to adapt to sleeves 400 with different diameters.

[0065] Specifically, in this embodiment, when installing the sleeve 400 on the variable-diameter shaft 300, the sleeve 400 can be first installed on the variable-diameter shaft 300, and then the diameter of the variable-diameter shaft 300 is increased by the adjusting member, so that the outer wall of the variable-diameter shaft 300 abuts against the inner wall of the sleeve 400. By forming an interference fit between the outer peripheral surface of the variable-diameter shaft 300 and the inner wall of the sleeve 400, the torque transmission effect during transmission is ensured.

[0066] Among them, it should be noted that since the change amount of the diameter of the variable-diameter shaft 300 is limited, in this embodiment, by adopting the cooperation mode of the variable-diameter shaft 300 and the assembly part 201, the different installation requirements of the small-diameter sleeve 400 and the large-diameter sleeve 400 are met. Exemplarily, in a color-coated aluminum production line, the diameters of the sleeves 400 are usually 405mm, 505mm, and 150mm. Therefore, the number of the assembly parts 201 is two, so that the two assembly parts 201 are respectively matched with the sleeves 400 with diameters of 405mm and 505mm, and the variable-diameter shaft 300 is used to install the sleeve 400 with a diameter of 150mm, thereby realizing the adaptation to multiple sleeves 400. When the diameter of the sleeve 400 is 200mm, 300mm, or 350mm, the diameter of the variable-diameter shaft 300 can be adjusted to adapt to sleeves 400 with different diameters.

[0067] In addition, it should be noted that when installing the sleeve 400 on the variable-diameter shaft 300, in order to prevent the sleeve 400 from displacing along its own axial direction, the coiler provided in this embodiment further includes a limiting member, and the limiting member is arranged on the tapered disk 200, thereby restricting the axial displacement of the sleeve 400.

[0068] In addition, the coiler provided in this embodiment further includes a first driving member 500, and the first driving member 500 is connected to one of the tapered disks 200. By driving the tapered disk 200 to rotate, the sleeve 400 is driven to rotate, so as to perform a winding operation on the workpiece to be wound on the sleeve 400.

[0069] Among them, in this embodiment, the first driving member 500 is a motor.

[0070] In an alternative embodiment, the number of the first driving members 500 is two, and the two first driving members 500 are respectively connected to the two tapered disks 200, so as to realize the double-end synchronous driving of the coiler, balance the transmission torque, and reduce the unbalanced load problem caused by single-side driving.

[0071] Please refer to Figure 1 and Figure 2 . In an alternative embodiment, the variable-diameter shaft 300 includes an airbag 303, and the adjusting member is communicated with the airbag 303 to inflate or deflate the airbag 303, so as to adjust the diameter of the variable-diameter shaft 300.

[0072] Specifically, in this embodiment, the variable-diameter shaft 300 has an inflatable structure, and the airbag 303 is connected to the adjusting member through a pipeline. When it is necessary to increase the diameter of the variable-diameter shaft 300, the adjusting member fills the airbag 303 with gas; when it is necessary to decrease the diameter of the variable-diameter shaft 300, the adjusting member causes the airbag 303 to release the gas therein, thereby realizing the rapid adjustment of the diameter of the variable-diameter shaft 300.

[0073] Specifically, in this embodiment, the adjusting member includes an air pump and a solenoid valve, so as to provide a compressed gas source through the air pump and control the air charging and discharging process through the solenoid valve.

[0074] Specifically, when it is necessary to install the sleeve 400 on the variable-diameter shaft 300, first deflate the variable-diameter shaft 300 to reduce the diameter of the variable-diameter shaft 300. After the sleeve 400 is sleeved on the variable-diameter shaft 300, then inflate it to the set pressure to increase the diameter of the variable-diameter shaft 300. A uniform contact pressure is formed between the outer surface of the inflated variable-diameter shaft 300 and the inner wall of the sleeve 400, ensuring the effective transmission of the driving torque. When disassembling, first deflate and decompress, and then the sleeve 400 can be conveniently and quickly removed.

[0075] Please refer to Figure 1 and Figure 2 . In an alternative embodiment, the variable-diameter shaft 300 further includes: a housing 302, on which a plurality of through grooves are formed; an airbag 303 disposed inside the housing 302, and an air inlet 301 communicating with the airbag 303 is provided on the housing 302; a plurality of abutting members 304, evenly and spacedly disposed on the circumferential side of the airbag 303. When the adjusting member inflates the airbag 303 through the air inlet 301, the abutting members 304 extend out of the through grooves to abut against the inner wall of the sleeve 400 on the variable-diameter shaft 300. When the adjusting member deflates the airbag 303 through the air inlet 301, the abutting members 304 retract into the through grooves and disengage from the inner wall of the sleeve 400 on the variable-diameter shaft 300.

[0076] Specifically, in this embodiment, the airbag 303 is of an annular hollow structure, made of a high-strength rubber material, and installed inside the housing 302. The air inlet 301 is communicated with the airbag 303, and the adjusting member inflates the airbag 303 through the air inlet 301 to enable the airbag 303 to generate a radial expansion force, thereby driving the abutting members 304 on the surface of the airbag 303 to extend out of the through grooves and move outward to abut against the inner wall of the sleeve 400 on the variable-diameter shaft 300, realizing the installation and fixation of the sleeve 400. When the adjusting member deflates the airbag 303 through the air inlet 301, the airbag 303 contracts, and the abutting members 304 retract into the through grooves under the action of the reset mechanism. At this time, the outer diameter of the variable-diameter shaft 300 decreases, facilitating the disassembly and assembly of the sleeve 400 on the variable-diameter shaft 300.

[0077] Specifically, in this embodiment, the abutting member 304 is in the shape of an arc plate, and the radian matches the inner wall of the sleeve 400 on the variable-diameter shaft 300, so that when the abutting member 304 extends, it can form a full circumferential and uniform contact with the inner wall of the sleeve 400 on the variable-diameter shaft 300, avoiding stress concentration caused by point contact, ensuring smooth torque transmission, and at the same time reducing the wear of the inner wall of the sleeve 400 on the variable-diameter shaft 300.

[0078] Specifically, the thickness of the abutting member 304 is slightly smaller than the width of the through groove, so as to ensure smooth movement of the abutting member 304 while avoiding obvious shaking.

[0079] In addition, it should be noted that in this embodiment, the number of the abutting members 304 is multiple, and the multiple abutting members 304 are arranged along the circumferential side of the airbag 303 to ensure that the sleeve 400 obtains a uniform radial supporting force during the winding operation.

[0080] Specifically, in an exemplary embodiment, the number of the abutting members 304 is set to six, and the respective abutting members 304 are evenly and spacedly distributed along the circumferential side of the airbag 303. Each abutting member 304 independently corresponds to a through groove and moves outward synchronously when the airbag 303 is inflated, so as to ensure balanced force on the sleeve 400 and prevent the problem of eccentric vibration during the winding process. In other embodiments, the number, size and spacing of the abutting members 304 can also be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.

[0081] In an alternative embodiment, the surface of the abutting member 304 that abuts against the inner wall of the sleeve 400 is processed with an anti-slip structure, so as to increase the friction coefficient between the abutting member 304 and the inner wall of the sleeve 400, prevent relative sliding during high-speed rotation, and ensure the reliability of power transmission.

[0082] In an alternative embodiment, the inflation port 301 adopts a quick-connect structure to facilitate quick connection and separation from the inflation pipeline. Among them, a one-way valve is provided inside the connector, which automatically closes the variable-diameter shaft 300 when the pipeline is disconnected to prevent gas leakage. The connector seal ring can be made of oil-resistant rubber material to ensure airtight performance.

[0083] Please refer to Figure 3 . In an alternative embodiment, the variable-diameter shaft 300 further includes a plurality of connecting members 305, and each abutting member 304 is correspondingly arranged on each connecting member 305, and the connecting members 305 are evenly and spacedly arranged on the circumferential side of the airbag 303.

[0084] Specifically, in this embodiment, the connecting member 305 is an arc-shaped sheet structure, the connecting member 305 extends along the axial direction of the airbag 303, and is evenly spaced along the circumferential direction of the airbag 303. The inner side of each connecting member 305 is fixedly connected to the outer surface of the airbag 303, and an abutting member 304 is installed on the outer side to enhance the overall rigidity and avoid local deformation under the action of air pressure.

[0085] Specifically, when the airbag 303 is inflated and expanded, the expansion force is evenly transmitted to each abutting member 304 through the connecting member 305. The arrangement of the connecting member 305 can avoid the flutter of the abutting member 304 caused by air pressure fluctuations, maintain the supporting stability, and at the same time avoid the problem that the reaction force of the abutting member 304 on the airbag 303 is concentrated.

[0086] Please refer to Figures 1 to 3 . In an alternative embodiment, the coiler further includes a locking member 600. The tapered disk 200 has a first mounting portion 202, and the variable-diameter shaft 300 has a second mounting portion 306. The first mounting portion 202 and the second mounting portion 306 are arranged in a matching manner. The locking member 600 sequentially passes through the first mounting portion 202 and the second mounting portion 306 to connect the tapered disk 200 and the variable-diameter shaft 300.

[0087] Specifically, when installing the variable-diameter shaft 300, the second mounting portions 306 at both ends of the variable-diameter shaft 300 are respectively matched with the first mounting portions 202 of the two tapered disks 200, and then the locking member 600 sequentially passes through the first mounting portion 202 and the second mounting portion 306 to realize the connection between the tapered disk 200 and the variable-diameter shaft 300, ensuring that the tapered disk 200 and the variable-diameter shaft 300 rotate coaxially.

[0088] Among them, the specific structures of the first mounting portion 202 and the second mounting portion 306 can be adaptively selected according to actual requirements, and this embodiment does not impose any restrictions on this.

[0089] Through the matching arrangement of the first mounting portion 202 and the second mounting portion 306, the variable-diameter shaft 300 can be accurately centered. While the locking member 600 bears the rotational torque, it can also axially position the tapered disk 200 and the variable-diameter shaft 300 to prevent the variable-diameter shaft 300 from axially moving during operation. When it is necessary to replace the variable-diameter shaft 300, only the locking member 600 needs to be disassembled to separate the variable-diameter shaft 300 from the tapered disk 200, thereby making the replacement work of the variable-diameter shaft 300 more convenient and improving the production efficiency.

[0090] In an alternative embodiment, the first mounting portion 202 is a mounting hole, and the second mounting portion 306 is a clamping portion, and the clamping portion is clamped in the mounting hole.

[0091] Specifically, in this embodiment, the first mounting portion 202 is a mounting hole, and the second mounting portion 306 is a clamping portion. The clamping portion can extend into the mounting hole and be clamped with the mounting hole, thereby realizing the quick connection between the tapered disk 200 and the variable-diameter shaft 300.

[0092] Specifically, in this embodiment, the mounting hole is a tapered hole, and its aperture gradually decreases along the axial direction to form a guiding inclined surface. The clamping portion is a tapered protrusion, and its outer contour is consistent with the taper of the mounting hole. When the clamping portion is inserted into the mounting hole, the conical surface fit produces a self-centering effect to ensure that the rotation axes of the two are automatically aligned.

[0093] Specifically, in an optional embodiment, an annular clamping groove may also be provided at the entrance of the tapered hole, and an elastic buckle is provided on the tapered protrusion of the clamping portion. When the clamping portion is completely inserted into the mounting hole, the elastic buckle snaps into the annular clamping groove to form an axial lock, thereby preventing the stepped shaft 300 from axially displacing during rotation.

[0094] Please refer to Figure 1 . In an optional embodiment, the assembling portion 201 is an annular groove, and the annular groove is arranged to match with one of the sleeves 400.

[0095] Specifically, in this embodiment, the width of the annular groove matches the flange thickness of the sleeve 400, and the groove wall is parallel to the axis of the conical disk 200, thereby ensuring the coaxiality after the sleeve 400 is installed. When the sleeve 400 is installed, the flange at its end is embedded into the annular groove. The side surface of the flange fits with the groove wall to achieve radial positioning, and the end surface of the flange contacts the groove bottom to achieve axial limit, thereby ensuring the stability and reliability of the installation of the sleeve 400.

[0096] Please refer to Figure 1 . In an optional embodiment, the coiler further includes a first guide rail 700 and a second driving member 900. At least one of the two conical disks 200 is arranged on the first guide rail 700, and the second driving member 900 is connected to at least one conical disk 200 to drive the conical disk 200 to move closer to or away from the other conical disk 200 along the first guide rail 700.

[0097] Specifically, in this embodiment, one of the two conical disks 200 is arranged on the first guide rail 700, and the other conical disk 200 is arranged on the ground or the base. The output end of the second driving member 900 is connected to the conical disk 200 arranged on the first guide rail 700, thereby driving the conical disk 200 to move closer to or away from the other conical disk 200 along the first guide rail 700, and further realizing the adjustment of the distance between the two conical disks 200, so that the coiler can adapt to the processing requirements of coils with different lengths, thereby greatly improving the versatility and production efficiency of the coiler.

[0098] Specifically, when processing a longer coil, the second driving member 900 drives the conical disk 200 to slide along the first guide rail 700 to move away from the other conical disk 200, so as to increase the distance between the two conical disks 200. When processing a shorter coil, the second driving member 900 drives the conical disk 200 to slide along the first guide rail 700 to move closer to the other conical disk 200, so as to reduce the distance between the two conical disks 200.

[0099] Meanwhile, when maintenance needs to be performed on the stepped shaft 300 or the conical disk 200, the distance between the conical disks 200 can be increased to obtain sufficient operating space. When the coiler is in a non-working state, the distance between the conical disks 200 can also be reduced to reduce the floor area of the equipment.

[0100] In another alternative embodiment, both of the tapered disks 200 are disposed on the first guide rail 700, and bidirectional synchronous adjustment is achieved through the second driving member 900. When the second driving member 900 drives the tapered disks 200 to move, the two tapered disks 200 can move synchronously closer to each other or away from each other, thereby improving the efficiency of pitch adjustment.

[0101] In other embodiments, the support member 100 can also be directly disposed on the first guide rail 700. In this regard, the operator can make an adaptive selection according to actual requirements, and this embodiment does not impose any restrictions. Exemplarily, the number of the support members 100 is two, one of the support members 100 is disposed on the first guide rail 700, and the other support member 100 is directly disposed on the ground.

[0102] In this embodiment, the second driving member 900 is a telescopic cylinder structure. The cylinder block of the cylinder is fixedly installed in the middle of the first guide rail 700, and both ends of the piston rod are respectively connected to the two tapered disks 200.

[0103] Specifically, the telescopic cylinder is a double-rod symmetric structure, and the two piston rods extend or retract synchronously from both sides of the cylinder block. When the cylinder is inflated, the two piston rods synchronously push the two tapered disks 200 away from each other; when exhausting, they synchronously pull back to make the two tapered disks 200 close to each other.

[0104] In other embodiments, the number of the second driving members 900 can also be two. The two second driving members 900 respectively control the two tapered disks 200, so that the positions of the individual tapered disks 200 can be adjusted respectively, improving the flexibility of the pitch adjustment of the winder.

[0105] Please refer to Figure 1 . In an alternative embodiment, the winder further includes a second guide rail 800 and a sliding seat 110. The support member 100 is disposed on the sliding seat 110, and the sliding seat 110 is slidably connected to the second guide rail 800.

[0106] Specifically, during the winding process, due to reasons such as uneven tension of the to-be-wound member, installation deviation, or uneven edges of the incoming material, the problem of the to-be-wound member running off track often occurs, resulting in uneven winding, uneven end faces, and in severe cases, even wrinkles or winding collapse of the to-be-wound member.

[0107] To solve the above problems, in this embodiment, each support member 100 is disposed on the sliding seat 110, and the sliding seat 110 is slidably connected to the second guide rail 800. When the operator finds that the to-be-wound member runs off track, the entire winder can be pushed to slide horizontally along the second guide rail 800, and the deviation amount can be compensated by adjusting the position of the winding center line. Thus, the winding alignment state can be quickly restored without interrupting the production process.

[0108] Specifically, in this embodiment, a locking structure is provided on the second guide rail 800. The locking structure is used to lock the relative position between the second guide rail 800 and the sliding seat 110. When the deviation problem occurs, only need to loosen the locking structure, push the rewinder to the appropriate position and then lock it again to complete the deviation correction.

[0109] Please refer to Figure 1 . In an alternative embodiment, the rewinder further includes a deviation correction assembly 120. The output end of the deviation correction assembly 120 is connected to the sliding seat 110. The deviation correction assembly 120 is configured to drive the sliding seat 110 to slide relative to the second guide rail 800.

[0110] Specifically, in this embodiment, the output end of the deviation correction assembly 120 is connected to the sliding seat 110 to drive the sliding seat 110 to slide relative to the second guide rail 800, thereby adjusting the position of the winding center line to compensate for the deviation amount and quickly restoring the winding alignment state.

[0111] Among them, the specific structure of the deviation correction assembly 120 can be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this. Exemplarily, the deviation correction assembly 120 is a telescopic cylinder structure. The piston rod of the cylinder is connected to the sliding seat 110, and the reciprocating movement of the sliding seat 110 is realized through air pressure drive. When it is detected that the coil is deviated, by adjusting the air intake of the cylinder, the piston rod is used to push the sliding seat 110 to accurately displace along the guide rail, thereby driving the entire rewinder to adjust its position.

[0112] Please refer to Figure 1 . In an alternative embodiment, the deviation correction assembly 120 includes a rotating member 121 provided with an external thread; a sliding member 122 connected to the bottom of the sliding seat 110 and the second guide rail 800 respectively. The sliding member 122 is sleeved on the rotating member 121, and the sliding member 122 is provided with an internal thread meshing with the external thread; a holding rod connected to the rotating member 121, and rotating the holding rod can drive the rotating member 121 to rotate.

[0113] Specifically, in this embodiment, the deviation correction assembly 120 includes a rotating member 121, a sliding member 122 and a holding rod. The rotating member 121 is a rod-shaped structure with a continuous external thread machined on its surface. The sliding member 122 is a block-shaped structure with a threaded through hole in the center for mating with the external thread of the rotating member 121. The upper surface of the sliding member 122 is fixedly connected to the bottom of the sliding seat 110, and the lower surface is provided with a guide groove for mating with the slide rail of the second guide rail 800. One end of the holding rod is fixedly connected to the end of the rotating member 121.

[0114] Specifically, when the operator rotates the holding rod, the rotating member 121 rotates accordingly. Since the sliding member 122 is restricted from rotating by the guide rail, the screw fit converts the rotational motion into a linear motion, and the sliding member 122 drives the sliding seat 110 to move along the guide rail, realizing the adjustment of the overall position of the winding machine. At the same time, due to the self-locking characteristic of the screw, the sliding seat 110 can be kept in the adjusted position with the second guide rail 800 unchanged.

[0115] Specifically, in this embodiment, the holding rod is an L-shaped rod member. The short side of the holding rod is key-connected to the rotating member 121, and anti-slip patterns are provided at the end of the long side. The operator can apply torque through the holding rod to drive the rotation of the rotating member 121. By adopting the key connection method, the torque can be reliably transmitted to the rotating member 121. Through the setting of the anti-slip patterns, the friction during operation can be increased, avoiding the occurrence of slipping problems.
