Referring to fig. 1 and 2, an embodiment of the present utility model provides a slitting machine, which includes a slitting device and a winding device 1. The slitting device is used for slitting incoming material strips into a plurality of material strips. The winding device 1 is used for winding the material strips formed by the division and forming a material roll A. The material tape may be a separator, or may be other material tapes that need to be slit, which is not limited herein.

In the embodiment of the application, the winding device 1 comprises a fixed base 10, a moving mechanism, a winding press roller 30, a swing arm mechanism 40 and a controller. The moving mechanism includes a moving beam 20, a first driving assembly 50a, a second driving assembly 50b, a first detecting assembly 60a, and a second detecting assembly 60b. The first driving assembly 50a and the second driving assembly 50b are both disposed on the fixed base 10. The movable cross member 20 has a first end 201 and a second end 202 opposite each other. The first end 201 and the second end 202 of the movable beam 20 are respectively disposed on the first driving assembly 50a and the second driving assembly 50b, such that the first driving assembly 50a and the second driving assembly 50b together drive the movable beam 20 to move along the first horizontal direction X1 relative to the fixed base 10. The first detecting assembly 60a is configured to detect a moving distance of the first end 201 of the moving beam 20 relative to the fixed base 10. The second detecting assembly 60b is configured to detect a moving distance of the second end 202 of the moving beam 20 relative to the fixed base 10. The swing arm mechanism 40 is provided on the movable cross member 20 and has a take-up shaft 41 for taking up the web and forming the web a. When the movable cross beam 20 moves along the first horizontal direction X1 relative to the fixed base 10, the swing arm mechanism 40 can be driven to move along the first horizontal direction X1, so as to drive the winding shaft 41 to move close to or away from the winding press roller 30, and the winding shaft 41 can be abutted against the winding press roller 30. The controller is electrically connected to the first drive assembly 50a, the second drive assembly 50b, the first detection assembly 60a, and the second detection assembly 60b. The controller is configured to control the first driving component 50a to adjust the moving distance of the first end 201 and/or control the second driving component 50b to adjust the moving distance of the second end 202 according to the difference between the detection result of the first detecting component 60a and the detection result of the second detecting component 60b, so as to compensate the moving distance error of the first end 201 and the second end 202 of the moving beam 20.

Thus, in the process of winding the winding shaft 41, the material roll a formed on the winding shaft 41 and the winding press 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 smoother. At the same time, the first driving assembly 50a and the second driving assembly 50b jointly drive the movable cross beam 20 to move along the first horizontal direction X1 relative to the fixed base 10, so as to drive the winding shaft 41 to be gradually far away from the winding press roller 30, so as to adapt to the material roll a with gradually increased diameter, and ensure that the pressing force between the material roll a on the winding shaft 41 and the winding press roller 30 is kept constant. Meanwhile, the first detection assembly 60a and the second detection assembly 60b are utilized to monitor the moving distance errors of the first end 201 and the second end 202 of the moving beam 20 in real time, so that the controller controls the first driving assembly 50a and/or the second driving assembly 50b to compensate the moving distance errors according to the detection result, and the moving distance errors of the first end 201 and the second end 202 of the moving beam 20 are at a lower level, so that the winding process requirements can be met.

Optionally, if the moving distance error between the moving distance of the first end 201 detected by the first detecting component 60a and the moving distance of the second end 202 detected by the second detecting component 60b exceeds a preset error range, the controller controls the first driving component 50a and/or the second driving component 50b to compensate the moving distance error until the moving distance error between the moving distance of the first end 201 detected by the first detecting component 60a and the moving distance of the second end 202 detected by the second detecting component 60b 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 movable beam 20 meets the winding process requirement, which is beneficial to improving the winding quality.

It should be noted that, the first driving assembly 50a controls the movement speed of the first end 201 to increase or decrease to adjust the movement distance of the first end 201, and/or the second driving assembly 50b controls the movement speed of the second end 202 to increase or decrease to adjust the movement distance of the second end 202, so as to compensate the movement distance error between the first end 201 and the second end 202 of the beam 20.

It should be noted that the controller may be an industrial personal computer, or may be any other control module having a control function, which is not limited herein.

In particular to the embodiment, the first detection assembly 60a includes a first grating scale 61a and a first grating read head 63a. The first grating scale 61a is mounted on the fixed base 10, and the first grating reading head 63a is mounted on the first end 201 of the movable beam 20 to move in synchronization with the first end 201 of the movable beam 20. The first grating reading head 63a is configured to detect a moving distance relative to the first grating ruler 61a, and is electrically connected to the controller, such that the first grating reading head 63a transmits a first detection signal representing a detection result to the controller.

In particular to the embodiment, the second detection assembly 60b includes a second grating scale 61b and a second grating reading head 63b. The second grating scale 61b is mounted on the fixed base 10 and the second grating reading head 63b is mounted on the second end 202 of the movable beam 20 to follow the second end 202 of the movable beam 20 to move synchronously. The second grating reading head 63b is configured to detect a moving distance relative to the second grating ruler 61b and is electrically connected to the controller, such 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 driving assembly 50a and/or the second driving assembly 50b to compensate for the movement distance error between the first end 201 and the second end 202 of the movable cross member 20 according to the comparison result (representing the movement distance error between the first end 201 and the second end 202 of the movable cross member 20).

In particular to the embodiment, the first drive assembly 50a includes a first lead screw 51a, a first rotary drive 52a, and a first lead screw nut. The first screw 51a is rotatably connected to the fixed base 10, and an axial direction of the first screw 51a is parallel to the first horizontal direction X1. The first rotary driving member 52a is mounted on the fixed base 10 and is in driving connection with the first screw 51a such that the first rotary driving member 52a can drive the first screw 51a to rotate. The first lead screw nut is threadedly coupled to the first lead screw 51a and fixedly coupled to the first end 201 of the movable cross member 20. The first rotary driving piece 52a is electrically connected with the controller so that the controller can control the first rotary driving piece 52a to drive the first screw 51a to rotate. In this way, when the first rotary driving 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, so as to drive the first end 201 of the movable beam 20 to move along the first horizontal direction X1 relative to the fixed base 10. Alternatively, the first rotary drive 52a may employ a motor.

The first driving unit 50a is not limited to the ball screw assembly. In other embodiments, the first driving assembly 50a may also adopt a gear and rack transmission structure, so long as the first end 201 of the movable beam 20 can be driven to move along the first horizontal direction X1 relative to the fixed base 10, which is not limited herein.

In particular to the embodiment, the second driving assembly 50b includes a second screw rod 51b, a second rotary driver 52b, and a second screw nut 53b. The second screw 51b is rotatably connected to the fixed base 10, and an axial direction of the second screw 51b is parallel to the first horizontal direction X1. The second rotary driving member 52b is mounted on the fixed base 10 and is in driving connection with the second screw 51b such that the second rotary driving member 52b can drive the second screw 51b to rotate. The second screw nut 53b is screwed onto the second screw 51b and is fixedly connected to the second end 202 of the movable cross member 20. The second rotary driving piece 52b is electrically connected with the controller so that the controller can control the second rotary driving piece 52b to drive the second screw 51b to rotate. In this way, when the second rotary driving 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, so as to drive the second end 202 of the movable beam 20 to move along the first horizontal direction X1 relative to the fixed base 10. In actual use, the first rotary driving member 52a and the second rotary driving member 52b respectively drive the first screw rod 51a and the second screw rod 51b to synchronously rotate, so that the first screw rod nut and the second screw rod nut 53b respectively drive the first end 201 and the second end 202 of the movable beam 20 to synchronously move along the first horizontal direction X1, thereby realizing that the movable beam 20 moves along the first horizontal direction X1 relative to the fixed base 10. Alternatively, the second rotary drive 52b may employ a motor.

The second driving unit 50b is not limited to the ball screw pair structure. In other embodiments, the second driving assembly 50b may also adopt a gear and rack transmission structure, so long as the second end 202 of the movable beam 20 can be driven to move relative to the fixed base 10, which is not limited herein.

In particular to the embodiment, the winding device 1 further comprises a first sliding rail 70a and a second sliding rail 70b, both of which are arranged on the fixed base 10. The first slide rail 70a and the second slide rail 70b are disposed parallel to the first horizontal direction X1. The first end 201 of the moving beam 20 is arranged on the first slide rail 70a by means of a first slider which is movable along the first slide rail 70 a. The second end 202 of the movable cross member 20 is disposed on the second slide rail 70b by a second slider that is movable along the second slide rail 70b. In this way, the first sliding block moves along the first sliding rail 70a and the second sliding block moves along the second sliding rail 70b, so as to guide the movement of the movable beam 20 along the first horizontal direction X1 relative to the fixed base 10, and avoid the offset of the movable beam 20.

In the embodiment of the present utility model, the take-up roller 30 is disposed below the swing arm mechanism 40, and the swing arm mechanism 40 is configured to be able to provide a preload force that causes the take-up shaft 41 to swing about a rotational axis. When the winding shaft 41 on the swing arm mechanism 40 swings downward to the lowest position (i.e., is in a free sagging state) about the rotation axis under the action of gravity, it can contact with the winding press roller 30, and under the action of the pre-tightening force, it presses against each other with the winding press roller 30 along the first horizontal direction X1, so that there is a pressing force therebetween (the direction of the pressing force is parallel to the first horizontal direction X1). Under the combined driving action of the first driving assembly 50a and the second driving assembly 50b, the movable cross beam 20 moves along the first horizontal direction X1 relative to the fixed base 10 to drive the winding shaft 41 on the swing arm mechanism 40 to approach or depart from the winding press roller 30, so that the pressing force between the material roll a on the winding shaft 41 and the winding press roller 30 is adjusted in the winding process of the winding shaft 41, and the pressing force between the material roll a on the winding shaft 41 and the winding press roller 30 is ensured to be kept constant.

In actual use, the material tape is wound by the winding shaft 41 on the swing arm mechanism 40, so that a material roll A is formed on the winding shaft 41. Before the winding shaft 41 starts to wind, the winding shaft 41 swings downwards to the lowest position (i.e. is in a free sagging state) around the rotation axis under the action of gravity, at this time, the winding shaft 41 and the winding press roller 30 are arranged side by side along the first horizontal direction X1 and just contact each other (no pressing force exists between the winding shaft 41 and the winding press roller 30 or the pressing force is small enough), and the winding shaft 41 and the winding press roller 30 are pressed against each other along the first horizontal direction X1 under the action of the pre-tightening force provided by the swing arm mechanism 40, so that the pressing force along the first horizontal direction X1 is generated between the winding press roller 30 and the winding shaft 41. In the process of winding the material belt by the winding shaft 41, the material belt is wound on the winding shaft 41 and forms a material roll A, the winding shaft 41 is pressed against each other along the first horizontal direction X1 by the material roll A and the winding press roller 30 on the winding shaft 41, so that the material roll A is more compact and flat, and meanwhile, the movable cross beam 20 is controlled to move along the first horizontal direction X1 relative to the fixed base 10 so as to drive the winding shaft 41 to gradually move away from the winding press roller 30, so that the pressing force between the material roll A on the winding shaft 41 and the winding press roller 30 is ensured not to be changed due to the increase of the diameter of the material roll A, namely, the pressing force between the material roll A on the winding shaft 41 and the winding press roller 30 is ensured to be kept constant.

Thus, in the process of winding the winding shaft 41, the self-gravity (vertical direction) of the swing arm mechanism 40 and the material roll a and the pressing force (first horizontal direction X1) applied to the material roll a by the winding press roller 30 are perpendicular to each other, so that the self-gravity of the swing arm mechanism 40 and the material roll a cannot influence the pressing force between the winding press roller 30 and the material roll a on the winding shaft 41. At the same time, the material roll A on the winding shaft 41 cannot swing around the rotation axis in the winding process, and the pretightening force provided by the swing arm mechanism 40 is also kept unchanged. Therefore, the only factor that causes the change in the pressing force between the winding roller 30 and the roll a on the winding shaft 41 is the diameter change of the roll a, so that the moving speed of the movable cross beam 20 is controlled according to the diameter change of the roll a, and 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 application simplifies the factors influencing the compression force between the rolling press roller 30 and the material roll A on the rolling shaft 41, greatly reduces the difficulty of controlling the compression force between the rolling press roller 30 and the material roll A on the rolling shaft 41 to be constant, and is beneficial to improving the rolling quality.

Referring to fig. 1 and 3, in some embodiments, the swing arm mechanism 40 includes a mount 42, a swing arm 43, and a swing drive 44. The mount 42 is provided on the movable cross member 20 to follow the movable cross member 20 to move together in the first horizontal direction X1. One end of the swing arm 43 is rotatably connected to the mounting base 42 about a rotation axis, and the take-up shaft 41 is mounted at the other end of the swing arm 43, so that the take-up shaft 41 can swing about the rotation axis following the swing arm 43. The rotation axis is parallel to a second horizontal direction X2, the second horizontal direction X2 being perpendicular to the first horizontal direction X1. The swing arm 43 can drive the winding shaft 41 to swing together with the material roll a on the winding shaft 41 when swinging around the rotation axis. The swing driving member 44 is connected with the mounting seat 42 and the swing arm 43, and the swing driving member 44 is used for providing the pretightening force for the swing arm 43, so that the swing arm 43 drives the material roll a on the winding shaft 41 and the winding press roller 30 to press against each other along the first horizontal direction X1.

Thus, when the material tape needs to be wound, the swing driving member 44 does not provide a pre-tightening force to the swing arm 43, so that the swing arm 43 and the winding shaft 41 on the swing arm 43 swing downwards around the rotation axis under the action of gravity until the winding shaft 41 swings to the lowest position (i.e. is in a free sagging state). Then, the movable cross beam 20 moves along the first horizontal direction X1 relative to the fixed base 10, so as to drive the winding shaft 41 on the swing arm 43 to gradually approach the winding press roller 30 until the winding shaft 41 just contacts the winding press roller 30 (at this time, no pressing force is generated between the winding shaft 41 and the winding press roller 30 or the pressing force is sufficiently small). Then, the swing driving member 44 applies a pre-tightening force to the swing arm 43, and under the effect of the pre-tightening force, the swing arm 43 drives the winding shaft 41 and the winding press roller 30 to abut against each other along the first horizontal direction X1, i.e. a pressing force along the first horizontal direction X1 is generated between the winding shaft 41 and the winding press roller 30. Then, the winding shaft 41 winds the material strip and forms a material roll a, and the material roll a on the winding shaft 41 and the winding press roller 30 are pressed against each other along the first horizontal direction X1 to generate a pressing force. In the process of winding by the winding shaft 41 (the diameter of the material roll A is gradually increased), the movable cross beam 20 is driven to move along the first horizontal direction X1 relative to the fixed base 10, so that the winding shaft 41 is driven to be gradually far away from the winding press roller 30, the material roll A with the continuously increased diameter is adapted, the pressing force between the material roll A on the winding shaft 41 and the winding press roller 30 is ensured to be kept constant, and the winding quality is improved. Alternatively, the swing driver 44 may employ an air cylinder.

In the embodiment, in order to realize simultaneous winding of multiple strips formed by slitting by the slitting device, a plurality of swing arm mechanisms 40 are provided, and a winding shaft 41 of each swing arm mechanism 40 is capable of winding one strip. The mounting seats 42 of each swing arm mechanism 40 are arranged on the movable cross beam 20 at intervals along a second horizontal direction X2, and the second horizontal direction X2 is parallel to the longitudinal direction of the movable cross 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. Thus, the distance between the installation seats 42 of the swing arm mechanisms 40 is adjusted, so that the distance between the winding shafts 41 is adjusted, winding of material strips with different width sizes is adapted, and compatibility of the winding device 1 is greatly improved.

Note that, each swing arm mechanism 40 is arranged at intervals along the second direction X2, and the roll a on the winding shaft 41 is located between two adjacent swing arm mechanisms 40, that is, the roll a is accommodated by using a space between two adjacent swing arm mechanisms 40. Therefore, the smaller the minimum value of the adjustable distance between the adjacent two swing arm mechanisms 40, the smaller the width of the roll a that can be accommodated between the adjacent two swing arm mechanisms 40, that is, the smaller the width of the web that can be wound by the winding shaft 41. That is, the smaller the minimum value of the interval between the adjacent two swing arm mechanisms 40 that can be adjusted, the smaller the width of the tape can be accommodated for winding, so that the compatibility of the winding device 1 is stronger.

In particular, in the illustrated embodiment, each swing arm mechanism 40 further includes a drive motor 45 and a transmission assembly 46. The driving motor 45 is installed on the installation seat 42, and the output shaft of the driving motor 45 is perpendicular to the winding shaft 41. The transmission assembly 46 is in transmission connection between the output shaft of the driving motor 45 and the winding shaft 41, so that the output shaft of the driving motor 45 can drive the winding shaft 41 to rotate through the transmission assembly 46, and the winding shaft 41 can wind the material belt. Thus, the axial direction of the output shaft of the driving motor 45 is the length direction of the driving motor 45, and since the output shaft of the driving motor 45 is perpendicular to the winding shaft 41, the length direction of the driving motor 45 is perpendicular to the winding shaft 41. Each swing arm mechanism 40 is arranged at intervals along a second horizontal direction X2 parallel to the axial direction of the winding shaft 41, and the length direction of the driving motor 45 is perpendicular to the winding shaft 41, so that the driving motor 45 does not occupy the space on two sides of the swing arm mechanisms 40 in the second horizontal direction X2, namely, the driving motor 45 does not occupy the space between two adjacent swing arm mechanisms 40, on one hand, each swing arm mechanism 40 can be close to each other as much as possible, so that the winding shaft 41 can wind a material belt with smaller width dimension, on the other hand, the installation space of the driving motor 45 is not limited by the narrow space between the two adjacent swing arm mechanisms 40, and the driving motor 45 with larger power can be installed, so that larger torque can be output, the winding shaft 41 is driven to wind a material belt with wider width, and the compatibility of the winding device 1 is greatly expanded. Alternatively, the drive motor 45 is mounted on top of the mount 42, and the axial direction of the output shaft of the drive motor 45 is substantially parallel to the vertical direction.

Since the output shaft of the driving motor 45 is perpendicular to the winding shaft 41, the transmission assembly 46 needs to implement 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.

It should be noted that, the driving motor 45 has a torque monitoring function, so that the power output can be adjusted according to the torque change, the tension of the material belt in the winding process can be ensured to be stable, and the winding quality is improved.

It should also be noted that "vertical" in this context should be understood to allow some error, so long as it is substantially vertical. "parallel" in this context should be understood to allow for some error, so long as it is substantially parallel.

In an embodiment of the present application, the transmission assembly 46 includes a right angle transmission unit 461, a parallel transmission unit 463, and a rotation shaft 465 rotatably connected to the mount 42. The rotation shaft 465 is perpendicular to the output shaft of the driving motor 45 and parallel to the take-up shaft 41, that is, the axial direction of the rotation shaft 465 is parallel to the second horizontal direction X2. The right angle transmission unit 461 is drivingly connected between the output shaft of the driving motor 45 and the rotating shaft 465 for transmitting the rotational movement of the output shaft of the driving motor 45 to the rotating shaft 465 at right angles. The parallel transmission unit 463 is drivingly connected between the rotating shaft 465 and the take-up shaft 41 for transmitting the rotational movement of the rotating shaft 465 in parallel to the take-up shaft 41. Further, an end of the swing arm 43 remote from the take-up shaft 41 is rotatably connected to a rotation shaft 465, the rotation axis being a central axis of the rotation shaft 465. In this way, the rotational movement of the rotation shaft 465 and the swinging movement of the swing arm 43 about the rotation axis do not affect each other. Alternatively, the end of the swing arm 43 remote from the take-up shaft 41 is bearing-mounted on the rotation shaft 465.

In some embodiments, the right angle drive unit 461 includes a driving magnetic wheel 4611 and a driven magnetic wheel 4613. The driving magnet wheel 4611 is coaxially mounted on the output shaft of the driving motor 45 so as to be rotatable in synchronization with the output shaft of the driving motor 45. The driven magnet wheel 4613 is coaxially mounted on the rotation shaft 465 so as to be rotatable in synchronization with the rotation shaft 465. The driving magnetic wheel 4611 and the driven magnetic wheel 4613 form magnetic transmission, so that the driving magnetic wheel 4611 can drive the driven magnetic wheel 4613 to rotate when rotating along with the output shaft of the driving motor 45, 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. Thus, the right-angle transmission between the output shaft of the driving motor 45 and the rotating shaft 465 is realized by utilizing the driving magnetic wheel 4611 and the driven magnetic wheel 4613, and the transmission mode of the driving magnetic wheel 4611 and the driven magnetic wheel 4613 belongs to a non-contact transmission mode, and the device has the advantages of strong power transmission capability, no abrasion, no dust, no noise, good dynamic balance, high position control precision, no maintenance, no replacement and the like.

It should be noted that the right angle driving unit 461 is not limited to a non-contact type magnetic driving method. In other embodiments, the right angle drive unit 461 may also employ a worm gear and worm contact drive. Specifically, the right angle drive unit 461 includes a worm and a worm wheel. The worm is coaxially mounted on the output shaft of the drive motor 45 such that the worm can rotate following the output shaft of the drive motor 45. The worm wheel is coaxially mounted on the rotation shaft 465 such that the worm wheel and the rotation shaft 465 can rotate synchronously. The worm is engaged with the worm wheel so that the worm can rotate the worm wheel when following the rotation of the output shaft of the driving motor 45, the worm wheel then drives the rotation shaft 465 to rotate, and the rotation shaft 465 then drives the take-up shaft 41 to rotate through the parallel transmission unit 463. That is, right angle transmission between the output shaft of the drive motor 45 and the rotation shaft 465 is achieved using a worm and a worm wheel.

In still other embodiments, the right angle drive unit 461 includes a drive bevel gear and a driven bevel gear. The drive bevel gear is coaxially mounted on the output shaft of the drive motor 45 such that the drive bevel gear can rotate with the output shaft of the drive motor 45. The driven bevel gear is coaxially mounted on the rotation shaft 465 such that the driven bevel gear and the rotation shaft 465 can be rotated in synchronization. The driving bevel gear is engaged with the driven bevel gear so that the driven bevel gear can be driven to rotate when the driving bevel gear follows the output shaft of the driving motor 45, 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. That is, the right angle transmission between the output shaft of the driving motor 45 and the rotation shaft 465 is achieved using the drive bevel gear and the driven bevel gear.

In particular embodiments, the parallel transmission unit 463 includes a driving wheel (not shown), a driven wheel (not shown), and a transmission belt. The drive wheel is coaxially mounted on the rotating shaft 465 such that the drive wheel can rotate along with the rotating shaft 465. The driven wheel is coaxially mounted on the take-up shaft 41 such that the driven wheel and the take-up shaft 41 can rotate synchronously. The transmission belt is sleeved between the driving wheel and the driven wheel, so that the driven wheel can be driven to rotate through the transmission belt when the driving wheel follows the rotation shaft 465 to rotate, and then the driven wheel drives the rewinding shaft 41 to rotate. That is, the parallel transmission between the rotating shaft 465 and the take-up shaft 41 is achieved using the driving pulley, the transmission belt, and the driven pulley.
