Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a winding device and a slitting machine. Background Art

[0002] In the battery manufacturing process, the incoming diaphragm material needs to be slit, and the multiple diaphragm strips formed by slitting need to be reeled up separately using a reeling device. The reeling device includes multiple swing arms, each of which is provided with a reeling shaft for reeling up the diaphragm strip. In order to make the reel wound on the reeling shaft more compact, it is necessary to use a pressure roller to press the reel during the reeling process, and use a cylinder to drive the swing arm to swing to adjust the distance between the reeling shaft and the pressure roller, thereby adjusting the pressure of the pressure roller on the reel to keep it stable.

[0003] During the winding process, the power required to be output by the cylinder is calculated using various factors that affect the pressure value of the pressure roller on the roll, thereby driving the swing arm to swing to the required angle. However, there are many factors that can affect the pressure value of the pressure roller on the roll, such as changes in the diameter of the roll, changes in the weight of the roll, and changes in the tilt angle of the swing arm. As the winding process continues, the errors in the diameter of the roll, the weight of the roll, and the tilt angle of the swing arm will become larger and larger, resulting in an increasing error in the calculated power value required to be output by the cylinder, which in turn leads to unstable pressure of the pressure roller on the roll, greatly reducing the winding quality.

[0014] In one embodiment, the transmission assembly includes a right-angle transmission unit, a parallel transmission unit, and a rotating shaft rotatably connected to the mounting seat, wherein the rotating shaft is perpendicular to the output shaft of the driving motor and parallel to the winding shaft;

[0015] The right-angle transmission unit is transmission-connected between the output shaft of the driving motor and the rotating shaft, and the parallel transmission unit is transmission-connected between the rotating shaft and the winding shaft.

[0016] In one of the embodiments, the right-angle transmission unit includes an active magnetic wheel and a driven magnetic wheel, the active magnetic wheel is coaxially mounted on the output shaft of the drive motor, the driven magnetic wheel is coaxially mounted on the rotating shaft, and a magnetic transmission is formed between the active magnetic wheel and the driven magnetic wheel.

[0017] In one embodiment, the winding device also includes a first drive component and a second drive component both disposed on the fixed base, the beam having a first end and a second end relative to each other, the first end and the second end being respectively disposed on the first drive component and the second drive component, and the first drive component and the second drive component jointly drive the beam to move relative to the fixed base along the first horizontal direction.

[0023] The above-mentioned winding device and slitting machine, when actually used, use the winding shaft on the swing arm mechanism to wind up the material strip and form a material roll on the winding shaft.

At this time, the winding shaft and the pressure roller are arranged side by side and in contact along the first horizontal direction, and under the action of the preload force provided by the swing arm mechanism, the winding shaft and the pressure roller press against each other along the first horizontal direction, so that a pressing force along the first horizontal direction is generated between the pressure roller and the winding shaft. During the process of the reel winding up the material strip, the material strip is wound on the reel and forms a material roll. The reel is pressed against the pressure roller along a first horizontal direction through the material roll thereon, so that the material roll is tighter and smoother. At the same time, the control beam is moved along the first horizontal direction relative to the fixed seat to drive the reel to gradually move away from the pressure roller, thereby ensuring that the pressing force between the material roll on the reel and the pressure roller does not change due to the increase in the diameter of the material roll, that is, ensuring that the pressing force between the material roll on the reel and the pressure roller remains constant.

[0024] In this way, during the process of winding the material strip on the winding shaft, the self-weight of the swing arm mechanism and the material roll (in the vertical direction) and the pressing force applied by the pressure roller to the material roll on the winding shaft (in the first horizontal direction) are perpendicular to each other, so the self-weight of the swing arm mechanism and the material roll will not affect the pressing force between the pressure roller and the material roll on the winding shaft. At the same time, during the winding process, the material roll on the winding shaft will not swing around the swing axis, and the preload force provided by the swing arm mechanism remains unchanged. Therefore, the only factor that causes the change in the pressing force between the pressure roller and the material roll on the winding shaft is the change in the diameter of the material roll, so that the crossbeam is controlled to move along the first horizontal direction according to the change in the diameter of the material roll, so as to ensure that the pressing force between the pressure roller and the material roll on the winding shaft remains constant. Compared with the prior art, the present application simplifies the factors affecting the pressing force between the pressure roller and the material roll on the winding shaft, greatly reduces the difficulty of controlling the pressing force between the pressure roller and the material roll on the winding shaft to remain constant, which is conducive to improving the winding quality.

[0034] See also Figure 1 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.

[0035] In the embodiment of the present application, the winding device 1 includes a fixed seat 10, a crossbeam 20, a pressure roller 30 and a swing arm mechanism 40. The crossbeam 20 is arranged on the fixed seat 10, and the pressure roller 30 is arranged below the swing arm mechanism 40. The swing arm mechanism 40 is arranged on the crossbeam 20, and has a winding shaft 41 for winding the above-mentioned material strip and forming a material roll A. The swing arm mechanism 40 is configured to provide a preload force that causes the winding shaft 41 to swing around a swing axis. When the winding shaft 41 on the swing arm mechanism 40 swings downward around the swing axis to the lowest position (i.e., in a free hanging state) under the action of its own gravity, it can be arranged side by side with the pressure roller 30 and contact along the first horizontal direction X1, and under the action of the above-mentioned preload force, the pressure roller 30 is pressed against each other along the first horizontal direction X1, so that there is a pressing force along the first horizontal direction X1 between the winding shaft 41 and the pressure roller 30. In which, the crossbeam 20 can be controlled to move relative to the fixed seat 10 along the first horizontal direction X1 to drive the winding shaft 41 on the swing arm mechanism 40 to move closer to or away from the pressure roller 30, thereby adjusting the clamping force between the material roll A on the winding shaft 41 and the pressure roller 30 during the winding process of the winding shaft 41.

[0036] The winding device 1, when actually used, uses the winding shaft 41 on the swing arm mechanism 40 to wind up the material strip, and forms a material roll A on the winding shaft 41. Before the winding shaft 41 starts to wind up, the winding shaft 41 swings downward around the swing axis to the lowest position (i.e., in a free hanging state) under the action of gravity. At this time, the winding shaft 41 and the pressure roller 30 are arranged side by side and in contact along the first horizontal direction X1, and under the action of the preload force provided by the swing arm mechanism 40, the winding shaft 41 and the pressure roller 30 press against each other along the first horizontal direction X1, so that a pressing force along the first horizontal direction X1 is generated between the pressure roller 30 and the winding shaft 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 presses against the pressure roller 30 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 control beam 20 is moved relative to the fixed seat 10 along the first horizontal direction X1 to drive the winding shaft 41 to gradually move away from the pressure roller 30, thereby ensuring that the pressing force between the material roll A on the winding shaft 41 and the pressure roller 30 does not change due to the increase in the diameter of the material roll A, that is, ensuring that the pressing force between the material roll A on the winding shaft 41 and the pressure roller 30 remains constant.

[0037] In this way, during the process of winding the material strip on the winding shaft 41, the self-weight of the swing arm mechanism 40 and the material roll A (along the vertical direction) and the pressing force (along the first horizontal direction X1) applied by the pressure roller 30 to the material roll A on the winding shaft 41 are perpendicular to each other, so the self-weight of the swing arm mechanism 40 and the material roll A will not affect the pressing force between the pressure roller 30 and the material roll A on the winding shaft 41. At the same time, during the winding process, the material roll A on the winding shaft 41 will not swing around the swing axis, and the preload force provided by the swing arm mechanism 40 will remain unchanged. Therefore, the only factor that causes the pressing force between the pressure roller 30 and the material roll A on the winding shaft 41 to change is the change in the diameter of the material roll A. Therefore, by controlling the crossbeam 20 to move along the first horizontal direction X1 according to the change in the diameter of the material roll A, the pressing force between the pressure roller 30 and the material 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 pressure roller 30 and the material roll A on the winding shaft 41, greatly reduces the difficulty of controlling the clamping force between the pressure roller 30 and the material roll A on the winding shaft 41 to remain constant, which is beneficial to improving the winding quality.

[0038] See also Figure 1 and Figure 2As 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 crossbeam 20 to move along the first horizontal direction X1 with the crossbeam 20. One end of the swing arm 43 is rotatably connected to the mounting seat 42 around the swing 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 swing axis with the swing arm 43. When the swing arm 43 swings around the swing axis, it can drive 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 winding shaft 41 and the pressure roller 30 to press against each other along the first horizontal direction X1. Preferably, the above-mentioned swing axis and the axial direction of the winding shaft 41 are parallel to the second horizontal direction X2, and the second horizontal direction X2 is perpendicular to the first horizontal direction X1.

[0039] In this way, when the material strip needs to be reeled up, first, the swing drive member 44 does not provide a preload force to the swing arm 43, so that the swing arm 43 drives the reel 41 to swing downward to the lowest position (i.e., in a free hanging state) under the action of gravity. Then, the control beam 20 is moved relative to the fixed seat 10 along the first horizontal direction X1, thereby driving the reel 41 on the swing arm 43 to gradually approach the pressure roller 30 until the reel 41 just contacts the pressure roller 30 (at this time, no pressing force is generated between the reel 41 and the pressure 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 reel 41 and the pressure roller 30 to press against each other along the first horizontal direction X1, so that a pressing force is generated between the reel 41 and the pressure 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 pressure roller 30 press against each other along the first horizontal direction X1 to generate a pressing force. While the reel 41 is reeling (the diameter of the reel A gradually increases), the crossbeam 20 is controlled to move relative to the fixed seat 10 along the first horizontal direction X1, thereby driving the reel 41 to gradually move away from the pressure roller 30 along the first horizontal direction X1 to adapt to the reel A with a gradually increasing diameter, ensuring that the pressing force between the reel A on the reel 41 and the pressure roller 30 remains constant, which is conducive to improving the reeling quality. Optionally, the swing drive member 44 can be a cylinder.

[0040] 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 beam 20 at intervals along the second horizontal direction X2, and the second horizontal direction X2 is perpendicular to the first horizontal direction X1. 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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 swing 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 swing 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Specifically in the embodiment, the parallel transmission unit 463 includes a driving wheel (not shown), a driven wheel (not shown) and a transmission belt 4633. 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 4633 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 4633, 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 4633 and the driven wheel.

[0051] See also Figure 1 and Figure 3In an embodiment of the present application, the winding device 1 further includes a controller and a first drive assembly 50a, a second drive assembly 50b, a first displacement detection assembly 60a and a second displacement detection assembly 60b, which are all electrically connected to the controller. The first drive assembly 50a and the second drive assembly 50b are both arranged on the fixed seat 10. The longitudinal direction of the beam 20 is parallel to the second horizontal direction X2, and the beam 20 has a first end 201 and a second end 202 as its longitudinal ends. The first end 201 and the second end 202 are respectively arranged on the first drive assembly 50a and the second drive assembly 50b, and the first drive assembly 50a and the second drive assembly 50b jointly drive the beam 20 to move relative to the fixed seat 10 along the first horizontal direction X1. The first displacement detection assembly 60a is used to detect the moving distance of the first end 201 relative to the fixed seat 10, and the second displacement detection assembly 60b is used to detect the moving distance of the second end 202 relative to the fixed seat 10.

[0052] The controller controls the first driving component 50a to adjust the moving distance of the first end 201 and / or controls the second driving component 50b to adjust the moving distance of the second end 202 through the difference between the detection results of the first displacement detection component 60a and the detection results of the second displacement detection component 60b, so as to compensate for the moving distance error between the first end 201 and the second end 202 of the beam 20.

[0053] Thus, during the winding process of the winding shaft 41, the first driving assembly 50a and the second driving assembly 50b jointly drive the cross beam 20 to move relative to the fixed seat 10 along the first horizontal direction X1, thereby driving the winding shaft 41 to gradually move away from the pressure roller 30, so as to ensure that the pressing force between the material roll A on the winding shaft 41 and the pressure roller 30 remains constant. At the same time, the first displacement detection assembly 60a and the second displacement detection assembly 60b are used to monitor the moving distance error between the first end 201 and the second end 202 of the cross beam 20 in real time, so that the controller controls the first driving assembly 50a and / or the second driving assembly 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 cross beam 20 is at a low level, ensuring that the winding process requirements can be met.

[0054] Optionally, if the moving distance error between the moving distance detected by the first displacement detection component 60a and the moving distance detected by the second displacement detection component 60b of 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 displacement detection component 60a and the moving distance detected by the second displacement detection component 60b of 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 beam 20 meets the winding process requirements, which is beneficial to improving the winding quality.

[0055] 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.

[0056] 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.

[0057] Specifically in the embodiment, the first displacement detection assembly 60a includes a first grating ruler 61a and a first grating reading head 63a. The first grating ruler 61a is mounted on the fixed seat 10, and the first grating reading head 63a is mounted on the first end 201 of the beam 20 to move synchronously along the first horizontal direction X1 with the first end 201 of the 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.

[0058] Specifically in the embodiment, the second displacement 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 seat 10, and the second grating reading head 63b is installed on the second end 202 of the beam 20 to move synchronously along the first horizontal direction X1 with the second end 202 of the 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 beam 20 according to the comparison result (the comparison result represents the moving distance error between the first end 201 and the second end 202 of the beam 20) to compensate for the moving distance error between the first end 201 and the second end 202 of the beam 20.

[0059] Specifically in the embodiment, the first drive assembly 50a includes a first screw rod 51a, a first rotation drive member 52a and a first screw nut. The first screw rod 51a is rotatably connected to the fixed seat 10, and the axial direction of the first screw rod 51a is parallel to the first horizontal direction X1. The first rotation drive member 52a is installed on the fixed seat 10 and is drivingly connected to the first screw rod 51a so that the first rotation 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 beam 20. The first rotation drive member 52a is electrically connected to the controller so that the controller can control the first rotation drive member 52a to drive the first screw rod 51a to rotate. In this way, when the first rotation 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 beam 20 to move relative to the fixed seat 10. Optionally, the first rotation drive member 52a can be a motor.

[0060] 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 beam 20 to move relative to the fixed seat 10 along the first horizontal direction X1, which is not limited here.

[0061] Specifically in the embodiment, the second drive assembly 50b includes a second screw rod 51b, a second rotating drive member 52b and a second screw nut 53b. The second screw rod 51b is rotatably connected to the fixed seat 10, and the axial direction of the second screw rod 51b is parallel to the first horizontal direction X1. The second rotating drive member 52b is installed on the fixed seat 10 and is drivingly connected to the second screw rod 51b so that the second rotating 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 beam 20. The second rotating drive member 52b is electrically connected to the controller so that the controller can control the second rotating drive member 52b to drive the second screw rod 51b to rotate. In this way, when the second rotating 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 beam 20 to move relative to the fixed seat 10. 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 beam 20 to move synchronously, thereby realizing the movement of the beam 20 relative to the fixed seat 10 along the first horizontal direction X1. Optionally, the second rotary drive member 52b can be a motor.

[0062] It should be noted that the second drive assembly 50b is not limited to a 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 beam 20 to move relative to the fixed seat 10 along the first horizontal direction X1, which is not limited here.

[0063] 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 seat 10. The first slide rail 70a and the second slide rail 70b are arranged parallel to each other, and the first slide rail 70a and the second slide rail 70b are parallel to the first horizontal direction X1. The first end 201 of the 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 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 beam 20 relative to the fixed seat 10 and avoid the deviation of the beam 20.

[0064] Please see again Figure 1As 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.
