[0002] In the battery manufacturing process, the incoming diaphragm material needs to be cut, and the multiple diaphragm strips formed by cutting need to be rolled up separately using a winding device. The winding device includes a crossbeam and multiple swing arms arranged on the crossbeam, and each swing arm is provided with a winding shaft for rolling up the diaphragm strip.
[0003] In order to make the roll wound on the winding shaft more compact, it is necessary to use the winding roller to press the roll during the winding of the diaphragm strip, and use the crossbeam to drive the swing arm to move to adjust the distance between the winding shaft and the winding roller, and then adjust the pressure of the winding roller on the roll to keep it stable. Therefore, the movement accuracy of the crossbeam is crucial to the quality of the roll formed by winding.
[0004] In the prior art, gears and racks are used to convert the rotational motion of the motor output into the linear motion of the beam, and the movement accuracy of the beam depends on the accuracy of the gears and racks.

When the gears and racks are used for transmission, the movement accuracy of the beam can only be controlled at about ±0.15mm, which cannot meet the winding requirements of the diaphragm strip.

[0032] See also Figure 1 and Figure 2 An embodiment of the utility model provides a slitting machine, including a slitting device and a winding device 1. The slitting device is used to slit a material strip into multiple strips. The winding device 1 is used to wind up the slitting strip and form a roll A. It should be noted that the strip can be a diaphragm or other strips that need to be slid, which is not limited here.
[0033] In an embodiment of the present application, the winding device 1 includes a fixed base 10, a moving mechanism, a winding roller 30, a swing arm mechanism 40 and a controller. The moving mechanism includes a moving beam 20, a first drive assembly 50a, a second drive assembly 50b, a first detection assembly 60a and a second detection assembly 60b. The first drive assembly 50a and the second drive assembly 50b are both arranged on the fixed base 10. The moving beam 20 has a first end 201 and a second end 202 opposite to each other. The first end 201 and the second end 202 of the moving beam 20 are respectively arranged on the first drive assembly 50a and the second drive assembly 50b, so that the first drive assembly 50a and the second drive assembly 50b jointly drive the moving beam 20 to move relative to the fixed base 10 along the first horizontal direction X1. The first detection assembly 60a is used to detect the moving distance of the first end 201 of the moving beam 20 relative to the fixed base 10. The second detection assembly 60b is used to detect the moving distance of the second end 202 of the moving beam 20 relative to the fixed base 10. The swing arm mechanism 40 is arranged on the moving beam 20, and has a reel 41 for reeling the material strip and forming a material roll A. When the moving beam 20 moves along the first horizontal direction X1 relative to the fixed base 10, it can drive the swing arm mechanism 40 to move along the first horizontal direction X1, thereby driving the reel 41 to move closer to or away from the reel roller 30, so that the reel 41 can abut against the reel roller 30. The controller is electrically connected to the first drive component 50a, the second drive component 50b, the first detection component 60a and the second detection component 60b. The controller is used to control the first drive component 50a to adjust the moving distance of the first end 201 and / or control the second drive component 50b to adjust the moving distance of the second end 202 according to the difference between the detection result of the first detection component 60a and the detection result of the second detection component 60b, so as to compensate for the moving distance error of the first end 201 and the second end 202 of the moving beam 20.
[0034] Thus, during the winding process of the winding shaft 41, the material roll A formed on the winding shaft 41 and the winding roller 30 are pressed against each other along the first horizontal direction X1, so that the material roll A on the winding shaft 41 is more compact and flat. At the same time, the first driving assembly 50a and the second driving assembly 50b jointly drive the moving crossbeam 20 to move relative to the fixed base 10 along the first horizontal direction X1, thereby driving the winding shaft 41 to gradually move away from the winding roller 30 to adapt to the material roll A with a gradually increasing diameter, and ensure that the pressing force between the material roll A on the winding shaft 41 and the winding roller 30 remains constant. At the same time, the first detection component 60a and the second detection component 60b are used to monitor the moving distance error between the first end 201 and the second end 202 of the moving beam 20 in real time, so that the controller controls the first drive component 50a and / or the second drive component 50b to compensate for the moving distance error according to the detection result, so that the moving distance error between the first end 201 and the second end 202 of the moving beam 20 is at a low level, ensuring that the winding process requirements can be met.
[0035] Optionally, if the moving distance error between the moving distance detected by the first detection component 60a at the first end 201 and the moving distance detected by the second detection component 60b at the second end 202 exceeds a preset error range, the controller controls the first drive component 50a and / or the second drive component 50b to compensate for the moving distance error until the moving distance error between the moving distance detected by the first detection component 60a at the first end 201 and the moving distance detected by the second detection component 60b at the second end 202 is within the preset error range, so as to ensure that the moving distance error between the first end 201 and the second end 202 of the moving beam 20 meets the winding process requirements, which is beneficial to improving the winding quality.
[0036] It should be noted that the moving distance of the first end 201 is adjusted by increasing or decreasing the moving speed of the first end 201 through the first driving component 50a; and / or the moving distance of the second end 202 is adjusted by increasing or decreasing the moving speed of the second end 202 through the second driving component 50b, thereby compensating for the moving distance error between the first end 201 and the second end 202 of the beam 20.
[0037] It should also be noted that the controller may be an industrial computer, or, of course, other control modules with control functions, which is not limited here.
[0038] Specifically in the embodiment, the first detection component 60a includes a first grating ruler 61a and a first grating reading head 63a. The first grating ruler 61a is mounted on the fixed base 10, and the first grating reading head 63a is mounted on the first end 201 of the moving beam 20 to move synchronously with the first end 201 of the moving beam 20. The first grating reading head 63a is used to detect the moving distance relative to the first grating ruler 61a, and is electrically connected to the controller, so that the first grating reading head 63a transmits a first detection signal representing the detection result to the controller.
[0039] Specifically in the embodiment, the second detection component 60b includes a second grating ruler 61b and a second grating reading head 63b. The second grating ruler 61b is installed on the fixed base 10, and the second grating reading head 63b is installed on the second end 202 of the moving beam 20 to move synchronously with the second end 202 of the moving beam 20. The second grating reading head 63b is used to detect the moving distance relative to the second grating ruler 61b, and is electrically connected to the controller so that the second grating reading head 63b transmits a second detection signal representing the detection result to the controller. The controller compares the first detection signal with the second detection signal, and controls the first drive component 50a and / or the second drive component 50b to compensate for the moving distance error between the first end 201 and the second end 202 of the moving beam 20 according to the comparison result (characterizing the moving distance error between the first end 201 and the second end 202 of the moving beam 20).
[0040] Specifically in the embodiment, the first drive assembly 50a includes a first screw rod 51a, a first rotating drive member 52a and a first screw nut. The first screw rod 51a is rotatably connected to the fixed base 10, and the axial direction of the first screw rod 51a is parallel to the first horizontal direction X1. The first rotating drive member 52a is installed on the fixed base 10 and is drivingly connected to the first screw rod 51a so that the first rotating drive member 52a can drive the first screw rod 51a to rotate. The first screw nut is threadedly connected to the first screw rod 51a and is fixedly connected to the first end 201 of the moving beam 20. The first rotating drive member 52a is electrically connected to the controller so that the controller can control the first rotating drive member 52a to drive the first screw rod 51a to rotate. In this way, when the first rotating drive member 52a drives the first screw rod 51a to rotate, the first screw nut moves along the axial direction of the first screw rod 51a, thereby driving the first end 201 of the moving beam 20 to move relative to the fixed base 10 along the first horizontal direction X1. Optionally, the first rotation driving member 52a may be a motor.
[0041] It should be noted that the first driving assembly 50a is not limited to the ball screw pair structure. In other embodiments, the first driving assembly 50a may also adopt a gear and rack transmission structure, as long as it can drive the first end 201 of the movable beam 20 to move relative to the fixed base 10 along the first horizontal direction X1, which is not limited here.
[0042] Specifically in the embodiment, the second drive assembly 50b includes a second screw rod 51b, a second rotary drive member 52b and a second screw nut 53b. The second screw rod 51b is rotatably connected to the fixed base 10, and the axial direction of the second screw rod 51b is parallel to the first horizontal direction X1. The second rotary drive member 52b is installed on the fixed base 10 and is drivingly connected to the second screw rod 51b so that the second rotary drive member 52b can drive the second screw rod 51b to rotate. The second screw nut 53b is threadedly connected to the second screw rod 51b and is fixedly connected to the second end 202 of the moving crossbeam 20. The second rotary drive member 52b is electrically connected to the controller so that the controller can control the second rotary drive member 52b to drive the second screw rod 51b to rotate. In this way, when the second rotary drive member 52b drives the second screw rod 51b to rotate, the second screw nut 53b moves along the axial direction of the second screw rod 51b, thereby driving the second end 202 of the moving crossbeam 20 to move relative to the fixed base 10 along the first horizontal direction X1. In actual use, the first rotary drive member 52a and the second rotary drive member 52b respectively drive the first screw rod 51a and the second screw rod 51b to rotate synchronously, so that the first screw nut and the second screw nut 53b respectively drive the first end 201 and the second end 202 of the moving beam 20 to move synchronously along the first horizontal direction X1, thereby realizing the movement of the moving beam 20 relative to the fixed base 10 along the first horizontal direction X1. Optionally, the second rotary drive member 52b can be a motor.
[0043] It should be noted that the second drive assembly 50b is not limited to the ball screw pair structure. In other embodiments, the second drive assembly 50b may also adopt a gear and rack transmission structure, as long as it can drive the second end 202 of the movable beam 20 to move relative to the fixed base 10, which is not limited here.
[0044] Specifically in the embodiment, the winding device 1 also includes a first slide rail 70a and a second slide rail 70b, both of which are arranged on the fixed base 10. The first slide rail 70a and the second slide rail 70b are arranged parallel to the first horizontal direction X1. The first end 201 of the moving beam 20 is arranged on the first slide rail 70a through a first slider, and the first slider is movable along the first slide rail 70a. The second end 202 of the moving beam 20 is arranged on the second slide rail 70b through a second slider, and the second slider is movable along the second slide rail 70b. In this way, the first slider moves along the first slide rail 70a and the second slider moves along the second slide rail 70b, so as to guide the movement of the moving beam 20 relative to the fixed base 10 along the first horizontal direction X1, thereby avoiding the displacement of the moving beam 20.
[0045] In the embodiment of the utility model, the winding roller 30 is arranged below the swing arm mechanism 40, and the swing arm mechanism 40 is configured to provide a preload force that causes the winding shaft 41 to swing around a rotation axis. When the winding shaft 41 on the swing arm mechanism 40 swings downward around the rotation axis to the lowest position (i.e., in a free hanging state) under the action of gravity, it can contact the winding roller 30, and under the action of the above-mentioned preload force, the winding roller 30 and the winding roller 30 are pressed against each other along the first horizontal direction X1, so that there is a pressing force between the two (the direction of the pressing force is parallel to the first horizontal direction X1). Among them, under the joint driving action of the first drive component 50a and the second drive component 50b, the movable beam 20 moves relative to the fixed base 10 along the first horizontal direction X1 to drive the winding shaft 41 on the swing arm mechanism 40 to approach or move away from the winding roller 30, thereby adjusting the clamping force between the material roll A on the winding shaft 41 and the winding roller 30 during the winding process of the winding shaft 41, ensuring that the clamping force between the material roll A on the winding shaft 41 and the winding roller 30 remains constant.
[0046] In actual use, the material strip is rolled up by the reel 41 on the swing arm mechanism 40, so that a material roll A is formed on the reel 41. Before the reel 41 starts to roll up, the reel 41 swings downward around the rotation axis to the lowest position (i.e., it is in a free hanging state) under the action of gravity. At this time, the reel 41 and the reel roller 30 are arranged side by side along the first horizontal direction X1 and just in contact with each other (there is no pressing force between the two or the pressing force is small enough), and under the action of the preload force provided by the swing arm mechanism 40, the reel 41 and the reel roller 30 are pressed against each other along the first horizontal direction X1, so that a pressing force along the first horizontal direction X1 is generated between the reel roller 30 and the reel 41. During the process of the winding shaft 41 winding up the material strip, the material strip is wound on the winding shaft 41 and forms a material roll A. The winding shaft 41 and the winding roller 30 are pressed against each other along the first horizontal direction X1 through the material roll A thereon, so that the material roll A is tighter and smoother; at the same time, the movable crossbeam 20 is controlled to move relative to the fixed base 10 along the first horizontal direction X1 to drive the winding shaft 41 to gradually move away from the winding roller 30, thereby ensuring that the clamping force between the material roll A on the winding shaft 41 and the winding roller 30 does not change due to the increase in the diameter of the material roll A, that is, ensuring that the clamping force between the material roll A on the winding shaft 41 and the winding roller 30 remains constant.
[0047] In this way, during the winding process of the winding shaft 41, the self-weight of the swing arm mechanism 40 and the roll A (vertical direction) and the pressing force (first horizontal direction X1) applied by the winding roller 30 to the roll A are perpendicular to each other, so the self-weight of the swing arm mechanism 40 and the roll A will not affect the magnitude of the pressing force between the winding roller 30 and the roll A on the winding shaft 41. At the same time, during the winding process, the roll A on the winding shaft 41 will not swing around the rotation axis, and the preload force provided by the swing arm mechanism 40 remains unchanged. Therefore, the only factor that causes the magnitude of the pressing force between the winding roller 30 and the roll A on the winding shaft 41 to change is the change in the diameter of the roll A. Therefore, by controlling the moving speed of the moving crossbeam 20 according to the change in the diameter of the roll A, the magnitude of the pressing force between the winding roller 30 and the roll A on the winding shaft 41 can be kept constant. Compared with the prior art, the present application simplifies the factors that affect the clamping force between the winding roller 30 and the material roll A on the winding shaft 41, greatly reduces the difficulty of controlling the clamping force between the winding roller 30 and the material roll A on the winding shaft 41 to remain constant, which is beneficial to improving the winding quality.
[0048] See also Figure 1 and Figure 3As shown, in some embodiments, the swing arm mechanism 40 includes a mounting seat 42, a swing arm 43 and a swing driving member 44. The mounting seat 42 is arranged on the moving crossbeam 20 to move along the first horizontal direction X1 with the moving crossbeam 20. One end of the swing arm 43 is rotatably connected to the mounting seat 42 around the rotation axis, and the winding shaft 41 is installed at the other end of the swing arm 43, so that the winding shaft 41 can swing around the rotation axis with the swing arm 43. The rotation axis is parallel to the second horizontal direction X2, and the second horizontal direction X2 is perpendicular to the first horizontal direction X1. When the swing arm 43 swings around the rotation axis, it can drive the winding shaft 41 and the material roll A on the winding shaft 41 to swing together. The swing driving member 44 is connected to the mounting seat 42 and the swing arm 43, and the swing driving member 44 is used to provide the above-mentioned preload force to the swing arm 43, so that the swing arm 43 drives the material roll A on the winding shaft 41 and the winding pressure roller 30 to press against each other along the first horizontal direction X1.
[0049] In this way, when the material strip needs to be wound up, first, the swing drive member 44 does not provide a preload force to the swing arm 43, so that the swing arm 43 and the winding shaft 41 on the swing arm 43 swing downward around the rotation axis under the action of gravity until the winding shaft 41 swings to the lowest position (i.e., in a free hanging state). Then, the movable crossbeam 20 moves relative to the fixed base 10 along the first horizontal direction X1, thereby driving the winding shaft 41 on the swing arm 43 to gradually approach the winding roller 30 until the winding shaft 41 just contacts the winding roller 30 (at this time, no pressing force is generated between the winding shaft 41 and the winding roller 30 or the pressing force is small enough). Then, the swing drive member 44 applies a preload force to the swing arm 43, and under the action of the preload force, the swing arm 43 drives the winding shaft 41 and the winding roller 30 to press against each other along the first horizontal direction X1, that is, a pressing force is generated between the winding shaft 41 and the winding roller 30 along the first horizontal direction X1. Then, the reel 41 reels the material strip and forms a reel A. The reel A on the reel 41 and the reel roller 30 press against each other along the first horizontal direction X1 to generate a pressing force. During the reeling process of the reel 41 (the diameter of the reel A gradually increases), the movable crossbeam 20 is driven to move relative to the fixed base 10 along the first horizontal direction X1, thereby driving the reel 41 to gradually move away from the reel roller 30 to adapt to the increasing diameter of the reel A, ensuring that the pressing force between the reel A on the reel 41 and the reel roller 30 remains constant, which is conducive to improving the reeling quality. Optionally, the swing drive member 44 can be a cylinder.
[0050] Specifically in the embodiment, in order to realize the simultaneous winding of multiple strips of material formed by the slitting device, a plurality of swing arm mechanisms 40 are provided, and the winding shaft 41 of each swing arm mechanism 40 can wind up one strip of material. The mounting seat 42 of each swing arm mechanism 40 is arranged on the moving beam 20 at intervals along the second horizontal direction X2, and the second horizontal direction X2 is parallel to the longitudinal direction of the moving beam 20. The position of each mounting seat 42 in the second horizontal direction X2 is adjustable, and the axial direction of the winding shaft 41 of each swing arm mechanism 40 is parallel to the second horizontal direction X2. In this way, by adjusting the spacing between the mounting seats 42 of each swing arm mechanism 40, the spacing between each winding shaft 41 can be adjusted to adapt to the winding of strips of different widths, thereby greatly improving the compatibility of the winding device 1.
[0051] It should be noted that the swing arm mechanisms 40 are arranged at intervals along the second direction X2, and the material roll A on the reel 41 is located between two adjacent swing arm mechanisms 40, that is, the space between two adjacent swing arm mechanisms 40 is used to accommodate the material roll A. Therefore, the smaller the minimum value of the adjustable spacing between two adjacent swing arm mechanisms 40, the smaller the width of the material roll A that can be accommodated between the two adjacent swing arm mechanisms 40, that is, the smaller the width of the material strip that can be reeled by the reel 41. In other words, the smaller the minimum value of the adjustable spacing between two adjacent swing arm mechanisms 40, the smaller the width of the material strip that can be reeled by the reel 41, so that the reel device 1 has stronger compatibility.
[0052] Specifically in the embodiment, each swing arm mechanism 40 also includes a drive motor 45 and a transmission assembly 46. The drive motor 45 is mounted on the mounting seat 42, and the output shaft of the drive motor 45 is perpendicular to the reel 41. The transmission assembly 46 is connected between the output shaft of the drive motor 45 and the reel 41, so that the output shaft of the drive motor 45 can drive the reel 41 to rotate through the transmission assembly 46, thereby causing the reel 41 to reel the material tape. In this way, the axial direction of the output shaft of the drive motor 45 is the length direction of the drive motor 45. Since the output shaft of the drive motor 45 is perpendicular to the reel 41, the length direction of the drive motor 45 is perpendicular to the reel 41. Each swing arm mechanism 40 is arranged at intervals along the second horizontal direction X2 parallel to the axial direction of the winding shaft 41. Since the length direction of the drive motor 45 is perpendicular to the winding shaft 41, the drive motor 45 does not occupy the space on both sides of the swing arm mechanism 40 in the second horizontal direction X2, that is, the drive motor 45 does not occupy the space between two adjacent swing arm mechanisms 40. On the one hand, each swing arm mechanism 40 can be as close as possible, so that the winding shaft 41 can reel in a smaller width material strip; on the other hand, the installation space of the drive motor 45 is not limited by the narrow space between two adjacent swing arm mechanisms 40, and a more powerful drive motor 45 can be installed, so that a greater torque can be output to drive the winding shaft 41 to reel in a wider width material strip, greatly expanding the compatibility of the winding device 1. Optionally, the drive motor 45 is installed on the top of the mounting seat 42, and the axial direction of the output shaft of the drive motor 45 is roughly parallel to the vertical direction.
[0053] It should be noted that, since the output shaft of the driving motor 45 is perpendicular to the winding shaft 41 , the transmission assembly 46 needs to realize right-angle transmission, that is, convert the rotational motion of the output shaft of the driving motor 45 into the rotational motion of the winding shaft 41 perpendicular thereto.
[0054] It should also be noted that the drive motor 45 has a torque monitoring function, so that the power output can be adjusted according to the torque change, ensuring that the tension of the material strip can remain stable during the winding process, which is beneficial to improving the winding quality.
[0055] It should also be noted that the term "perpendicular" in this article should be understood as allowing a certain error, as long as it is roughly perpendicular. The term "parallel" in this article should be understood as allowing a certain error, as long as it is roughly parallel.
[0056] In the embodiment of the present application, the transmission assembly 46 includes a right-angle transmission unit 461, a parallel transmission unit 463, and a rotating shaft 465 rotatably connected to the mounting seat 42. The rotating shaft 465 is perpendicular to the output shaft of the driving motor 45 and parallel to the winding shaft 41, that is, the axial direction of the rotating shaft 465 is parallel to the second horizontal direction X2. The right-angle transmission unit 461 is transmission-connected between the output shaft of the driving motor 45 and the rotating shaft 465, and is used to transmit the rotational motion of the output shaft of the driving motor 45 to the rotating shaft 465 at right angles. The parallel transmission unit 463 is transmission-connected between the rotating shaft 465 and the winding shaft 41, and is used to transmit the rotational motion of the rotating shaft 465 to the winding shaft 41 in parallel. Further, one end of the swing arm 43 away from the winding shaft 41 is rotatably connected to the rotating shaft 465, and the above-mentioned rotation axis is the central axis of the rotating shaft 465. In this way, the rotational motion of the rotating shaft 465 and the swinging motion of the swing arm 43 around the rotation axis do not affect each other. Optionally, one end of the swing arm 43 away from the winding shaft 41 is installed on the rotating shaft 465 through a bearing.
[0057] In some embodiments, the right-angle transmission unit 461 includes an active magnetic wheel 4611 and a driven magnetic wheel 4613. The active magnetic wheel 4611 is coaxially mounted on the output shaft of the drive motor 45 so as to be able to rotate synchronously with the output shaft of the drive motor 45. The driven magnetic wheel 4613 is coaxially mounted on the rotating shaft 465 so as to be able to rotate synchronously with the rotating shaft 465. A magnetic transmission is formed between the active magnetic wheel 4611 and the driven magnetic wheel 4613, so that when the active magnetic wheel 4611 rotates following the output shaft of the drive motor 45, the driven magnetic wheel 4613 can drive the driven magnetic wheel 4613 to rotate, and the driven magnetic wheel 4613 then drives the rotating shaft 465 to rotate, and the rotating shaft 465 then drives the winding shaft 41 to rotate through the parallel transmission unit 463. In this way, the active magnetic wheel 4611 and the driven magnetic wheel 4613 are used to realize the right-angle transmission between the output shaft of the drive motor 45 and the rotating shaft 465, and the transmission method of the active magnetic wheel 4611 and the driven magnetic wheel 4613 is a non-contact transmission method, which has the advantages of strong power transmission capability, no wear, no dust, no noise, good dynamic balance, high position control accuracy, maintenance-free, and replacement-free.
[0058] It should be noted that the right-angle transmission unit 461 is not limited to the non-contact magnetic transmission method. In other embodiments, the right-angle transmission unit 461 can also adopt the contact transmission method of the worm gear and the worm. Specifically, the right-angle transmission unit 461 includes a worm and a worm wheel. The worm is coaxially mounted on the output shaft of the drive motor 45, so that the worm can rotate with the output shaft of the drive motor 45. The worm wheel is coaxially mounted on the rotating shaft 465, so that the worm wheel and the rotating shaft 465 can rotate synchronously. The worm is meshed with the worm wheel, so that the worm can drive the worm wheel to rotate when the worm rotates with the output shaft of the drive motor 45, and the worm wheel drives the rotating shaft 465 to rotate, so that the rotating shaft 465 drives the winding shaft 41 to rotate through the parallel transmission unit 463. In other words, the right-angle transmission between the output shaft of the drive motor 45 and the rotating shaft 465 is realized by using the worm and the worm wheel.
[0059] In some other embodiments, the right-angle transmission unit 461 includes a driving bevel gear and a driven bevel gear. The driving bevel gear is coaxially mounted on the output shaft of the driving motor 45, so that the driving bevel gear can rotate together with the output shaft of the driving motor 45. The driven bevel gear is coaxially mounted on the rotating shaft 465, so that the driven bevel gear and the rotating shaft 465 can rotate synchronously. The driving bevel gear is meshed with the driven bevel gear, so that when the driving bevel gear rotates with the output shaft of the driving motor 45, it can drive the driven bevel gear to rotate, and the driven bevel gear then drives the rotating shaft 465 to rotate, and the rotating shaft 465 then drives the winding shaft 41 to rotate through the parallel transmission unit 463. In other words, the right-angle transmission between the output shaft of the driving motor 45 and the rotating shaft 465 is realized by using the driving bevel gear and the driven bevel gear.
[0060] Specifically in the embodiment, the parallel transmission unit 463 includes a driving wheel (not shown), a driven wheel (not shown) and a transmission belt. The driving wheel is coaxially mounted on the rotating shaft 465, so that the driving wheel can rotate along with the rotating shaft 465. The driven wheel is coaxially mounted on the winding shaft 41, so that the driven wheel and the winding shaft 41 can rotate synchronously. The transmission belt is sleeved between the driving wheel and the driven wheel, so that when the driving wheel rotates along with the rotating shaft 465, the driven wheel can drive the driven wheel to rotate through the transmission belt, and the driven wheel then drives the winding shaft 41 to rotate. In other words, the parallel transmission between the rotating shaft 465 and the winding shaft 41 is realized by using the driving wheel, the transmission belt and the driven wheel.
[0061] Please see again Figure 1 As shown, the number of winding devices 1 is set to two, and the two winding devices 1 are arranged opposite to each other in the first horizontal direction X1. The slitting device slits the incoming material strip into multiple strips, wherein part of the material strip is respectively wound up by each winding shaft 41 of one of the winding devices 1, and another part of the material strip is respectively wound up by each winding shaft 41 of another winding device 1, thereby ensuring that each strip formed by slitting is wound up at the same time.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
