[0065] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0066] like Figures 1 to 7 As shown, an embodiment of the present application provides a rewinding device. The rewinding device includes a frame 1, at least two unwinding roller mechanisms 2, a rewinding mechanism 3, and a pressing mechanism 4. The at least two unwinding roller mechanisms 2 are mounted on the frame 1. The unwinding roller mechanisms 2 are used to place single-layer coils. The rewinding mechanism 3 is mounted on the frame 1. The rewinding mechanism 3 is used to wind the single-layer coils on the at least two unwinding roller mechanisms 2 into multi-layer coils. The pressing mechanism 4 is mounted on the frame 1. The pressing mechanism 4 is used to press the multi-layer coils.

[0067] In this embodiment, a single-layer coil is placed via a feed roller mechanism 2, and at least two single-layer coils are wound into a multi-layer coil using a rewinding mechanism 3. During the coiling process, a clamping mechanism 4 presses against the multi-layer coil to ensure tightness and a properly wound coil. Furthermore, the design of the clamping mechanism 4 eliminates the need for adhesive tape at the starting point of the multi-layer coil, simplifying the winding process and optimizing the quality of the finished multi-layer coil.

[0068] It is understood that the frame 1, as the main body for mounting the unwinding roller mechanism 2, rewinding mechanism 3, and clamping mechanism 4, determines the overall position of the rewinding equipment, facilitating integrated transport. The frame 1 can be configured in a square shape. One side of the frame 1 serves as the winding station, where the unwinding roller mechanism 2, rewinding mechanism 3, clamping mechanism 4, as well as the rotation mechanism 5, winding transport mechanism 6, deviation correction mechanism 7, and metering mechanism 8 (described later) are all located. The frame 1 can be made of austenitic stainless steel.

[0069] Each unwinding roller mechanism 2 can hold a single layer of coiled material. By arranging at least two unwinding roller mechanisms 2 on the frame 1, multiple single-layer coils can be placed on the corresponding unwinding roller mechanisms 2 as needed. When the rewinding mechanism 3 is in operation, the desired multi-layer coils can be formed. For example, if the frame 1 is equipped with six unwinding roller mechanisms 2, each one can hold a single layer of coiled material, which can be the same or different. This allows for reliable six-layer composite stacking molding.

[0070] The single-layer coil may be a metal sheet coil.

[0071] like Figure 5 As shown, in some embodiments, the clamping mechanism 4 includes a first driving member 41 and a clamping wheel 42. The first driving member 41 is mounted on the frame 1. The clamping wheel 42 is connected to the first driving member 41 and is configured to move closer to or away from the multi-layer web under the action of the first driving member 41, and the clamping wheel 42 is in rotational contact with the multi-layer web.

[0072] It is understood that the first drive member 41 can drive the pinch wheel 42 toward or away from the multi-layered web. The first drive member 41 adjusts the position of the pinch wheel 42 to ensure that the pinch wheel 42 always acts on the multi-layered web during winding, keeping the multi-layered web under pressure. This ensures that the multi-layered web does not become loose, thereby improving the winding effect.

[0073] As the multi-layered coil is continuously wound and formed, the radius of the multi-layered coil gradually increases. The first drive member 41 can be used to drive the pinch wheel 42 gradually away from the multi-layered coil, ensuring that the pinch wheel 42 still exerts sufficient force on the multi-layered coil. The pinch wheel 42 rotates against the multi-layered coil, allowing the pinch wheel 42 and the multi-layered coil to rotate relative to each other and compress the multi-layered coil, ensuring that the coil does not become loose during the winding process.

[0074] As the multi-layered web is gradually wound, the first drive member 41 drives the pinch wheel 42 to gradually move away from the multi-layered web, but it is necessary to ensure that the pinch wheel 42 is always in rotational contact with the outer surface of the multi-layered web so that the pinch wheel 42 can always exert force on the multi-layered web. After the multi-layered web is wound and removed from the rewinding mechanism 3, the first drive member 41 can drive the pinch wheel 42 to return to its original position to facilitate subsequent winding.

[0075] Please continue reading Figure 5 In some embodiments, the first driving member 41 includes a cylinder 411, a guide mechanism 412, and a sliding seat 413. The cylinder 411 is mounted on the frame 1. The guide mechanism 412 is mounted on the frame 1. The piston rod of the cylinder 411 is connected to the pressure wheel 42. The sliding seat 413 is slidably connected to the guide mechanism 412. The piston rod is connected to the sliding seat 413.

[0076] It will be appreciated that the retracting and extending action of the piston rod of the air cylinder 411 drives the pinch wheel 42 toward or away from the multi-layer web, thereby enabling the pinch wheel 42 to exert force on the multi-layer web during its winding process, thereby ensuring that the multi-layer web does not unwind. The guide mechanism 412 cooperates with the sliding seat 413 to limit the movement of the pinch wheel 42, ensuring that the pinch wheel 42 moves only toward or away from the multi-layer web.

[0077] The guide mechanism 412 may be configured as a guide rail, and the sliding seat 413 is slidably mounted on the guide rail.

[0078] In some embodiments, the cylinder 411 can be electrically controlled by a controller provided on the frame 1. The driving instruction of the cylinder 411 can be input into the controller so that the cylinder 411 controls the movement of the piston rod in response to the driving instruction. Alternatively, the controller can also control the movement of the piston rod based on received coil pressure parameters, coil meter parameters, coil winding speed parameters, etc. Alternatively, the clamping mechanism 4 can also include a pressure gauge that can monitor the force exerted by the clamping wheel 42 on the multi-layer coil and can control the movement of the cylinder 411 based on the preset force. It is sufficient to ensure that after the piston rod is actuated, the clamping wheel 42 can always rotate and abut against the outer ring of the multi-layer coil.

[0079] The first driving member 41 may further include a bracket, on which the cylinder 411 and guide mechanism 412 are mounted and secured to the frame 1 via the bracket. The guide wheel can be rotatably mounted on a U-shaped member, which is secured to the free end of the piston rod. This allows the piston rod to drive the guide wheel and ensures its rotation.

[0080] like Figure 1 and Figure 2As shown, in some embodiments, at least two pressing mechanisms 4 are provided, and at least two pressing mechanisms 4 are provided around the rewinding mechanism 3 .

[0081] The plurality of pressing mechanisms 4 can be used to press the plurality of positions of the multi-layer coil, thereby further ensuring that the multi-layer coil is not loosened and improving the winding effect.

[0082] like Figure 2 As shown, there are three pressing mechanisms 4, and the three pressing mechanisms 4 are arranged at 120° intervals. Thus, it can be ensured that the pressing mechanisms 4 exert uniform force on the multi-layer coils, thereby ensuring the stability of the multi-layer coils.

[0083] Of course, the number of the pressing mechanisms 4 can also be four, five or any other number. The multiple pressing mechanisms 4 can be distributed symmetrically along the center of the rewinding mechanism 3, or distributed in any manner around the rewinding mechanism 3.

[0084] like Figure 3 As shown, in some embodiments, the unwinding roller mechanism 2 includes a first pneumatic shaft 21 and a brake 22. The first pneumatic shaft 21 is used to place the single-layer web. The brake 22 is mounted on the frame 1. The brake 22 is connected to the first pneumatic shaft 21 and is used to apply a force to the first pneumatic shaft 21 opposite to the direction of the single-layer web's transport, thereby maintaining tension on the single-layer web.

[0085] It is understood that a single-layer coil can be sleeved onto the first pneumatic shaft 21, and the first pneumatic shaft 21 can adjust its shaft diameter based on the inner diameter of the single-layer coil to accommodate different products and models of single-layer coils. The brake 22 is used to apply a force to the first pneumatic shaft 21 opposite to the direction of transmission of the single-layer coil, thereby keeping the single-layer coil in a straight state. That is, under the drive of the rewinding mechanism 3, the single-layer coil will continuously be wound out of the metal sheet. Without the brake 22 to provide a damping force, the metal sheet would be difficult to straighten, resulting in defects such as wrinkles and loose coils in the wound multi-layer coil. In the embodiment of the present application, the brake 22 is used to act on the first pneumatic shaft 21 to provide a damping force on the winding of the single-layer coil, thereby ensuring that the single-layer coil remains straight during the process of being wound into a multi-layer coil.

[0086] The brake 22 is a magnetic powder brake 22 .

[0087] The first pneumatic shaft 21 can be mounted on a bearing seat and rotatably mounted on the frame 1 using the bearing seat. The first pneumatic shaft 21 can be provided with multiple pneumatically adjustable curved blades. When the first pneumatic shaft 21 is inflated, the curved blades can move away from the first pneumatic shaft 21, thereby increasing the shaft diameter of the first pneumatic shaft 21 to accommodate single-layer coils with large inner diameters. When the first pneumatic shaft 21 is deflated, the curved blades can move closer to the first pneumatic shaft 21, thereby decreasing the shaft diameter of the first pneumatic shaft 21 to accommodate single-layer coils with small inner diameters.

[0088] In some embodiments, the first air shaft 21 is connected to a first air intake pipe and a first air exhaust pipe. A first air intake valve is mounted on the first air intake pipe. A first air exhaust valve is mounted on the first air exhaust pipe. A controller is mounted on the frame 1. The controller is electrically connected to the first air intake valve and the first air exhaust valve.

[0089] It is understood that the first inflation shaft 21 may include an airbag. A controller controls the opening and closing of a first air inlet valve. When the first air inlet valve is open, the airbag can be inflated via the first air inlet pipe; when the first air inlet valve is closed, inflation in the first air inlet pipe is terminated. A controller controls the opening and closing of a first exhaust valve. When the first exhaust valve is open, the airbag can be deflated via the first exhaust pipe; when the first exhaust valve is closed, deflation in the first exhaust pipe is terminated.

[0090] When the airbag is inflated using the first air inlet pipe, it gradually expands, causing the curved sheet to gradually move away from the first inflatable shaft 21, thereby increasing the shaft diameter of the first inflatable shaft 21 to accommodate single-layer coils with large inner diameters. When the airbag is deflated using the first exhaust pipe, it gradually contracts, causing the curved sheet to gradually move closer to the first inflatable shaft 21, thereby decreasing the shaft diameter of the first inflatable shaft 21 to accommodate single-layer coils with small inner diameters.

[0091] In the embodiment of the present application, automatic control of the first pneumatic shaft 21 can be achieved by ensuring that the first pneumatic shaft 21 is always connected to the first air inlet pipe and the first exhaust pipe.

[0092] The first air inlet pipe and the first air outlet pipe are both arranged at one end of the first inflation shaft 21 facing the frame 1 .

[0093] In some embodiments, the controller mounted on the frame 1 may also be provided with a first button and a second button. The first button may be used to control the first air inlet valve, and the second button may be used to control the second air outlet valve. Thus, the controller may be used to manually control the inflation and deflation of the first air shaft 21, thereby enabling the first air shaft 21 to rapidly tighten and loosen the single-layer coil core, thereby improving the efficiency of loading and unloading the single-layer coil.

[0094] like Figure 4 As shown, in some embodiments, the rewinding mechanism 3 includes a second driving member 31 and a second air shaft 32. The second driving member 31 is mounted on the frame 1. The second air shaft 32 is used to place the multi-layer coil. The second air shaft 32 is connected to the second driving member 31.

[0095] It is understood that the multi-layered coil can be sleeved onto the second inflatable shaft 32. The second inflatable shaft 32 can adjust its shaft diameter based on the inner diameter of the multi-layered coil to accommodate different products and models of multi-layered coils. The second drive member 31 can drive the second inflatable shaft 32 to rotate, thereby achieving continuous winding and forming of the multi-layered coil.

[0096] The second driving member 31 includes a motor, a reducer, etc., and the motor and the reducer cooperate to drive the second pneumatic shaft 32 to rotate.

[0097] In some embodiments, the motor can be controlled by a controller. Based on the pressure signal obtained by the pressure sensor 62, the controller can adjust the motor speed, etc., thereby adjusting the force exerted by the second air shaft 32 on the multi-layer web output. Based on this closed-loop control, the tension during the winding process can be adjusted in real time.

[0098] The second pneumatic shaft 32 can be mounted on a bearing seat and rotatably mounted on the frame 1 using the bearing seat. The second pneumatic shaft 32 can be provided with multiple pneumatically adjustable curved blades. When the second pneumatic shaft 32 is inflated, the curved blades can move away from the second pneumatic shaft 32, thereby increasing the shaft diameter of the second pneumatic shaft 32 to accommodate multi-layer coils with large inner diameters. When the second pneumatic shaft 32 is deflated, the curved blades can move toward the second pneumatic shaft 32, thereby decreasing the shaft diameter of the second pneumatic shaft 32 to accommodate multi-layer coils with small inner diameters.

[0099] In some embodiments, the rewinding mechanism 3 further includes a clutch 33. The clutch 33 is connected between the second driving member 31 and the second pneumatic shaft 32. The clutch 33 has a preset torque value. The clutch 33 is configured to disconnect the second driving member 31 from the second pneumatic shaft 32 when an external force exceeds the preset torque value.

[0100] It is understood that, based on the design of the clutch 33, when the external force acting on the rewinding mechanism 3 exceeds a preset torque value, the second driving member 31 can be disconnected from the second pneumatic shaft 32. In this case, the output shaft of the second driving member 31 can idle, or the second pneumatic shaft 32 can rotate independently under the drive of the external force.

[0101] Based on the above design, when the operator touches the second air expansion shaft 32 or the multi-layer coil due to positioning errors, the output shaft of the second driving member 31 can be made to idle to prevent the operator from being scratched by the second air expansion shaft 32 or the multi-layer coil, thereby improving the safety of the rewinding equipment.

[0102] In some embodiments, the preset torque value can be set to 10N (Newtons). When the external force exceeds 10N, the clutch 33 disengages, disconnecting the second drive member 31 from the second pneumatic shaft 32. Of course, the preset torque value can also be set to other values, which can be reasonably set based on actual usage requirements.

[0103] The clutch 33 may be a magnetic powder clutch 33 .

[0104] In some embodiments, the second inflation shaft 32 is connected to a second air intake pipe and a second air exhaust pipe. A second air intake valve is mounted on the second air intake pipe. A second air exhaust valve is mounted on the second air exhaust pipe. A controller is mounted on the frame 1. The controller is electrically connected to the second air intake valve and the second air exhaust valve.

[0105] It is understood that the second inflation shaft 32 may contain an airbag. The controller controls the opening and closing of the second air inlet valve. When the second air inlet valve is open, the airbag can be inflated via the second air inlet pipe; when the second air inlet valve is closed, inflation in the second air inlet pipe is terminated. The controller controls the opening and closing of the second exhaust valve. When the second exhaust valve is open, the airbag can be deflated via the second exhaust pipe; when the second exhaust valve is closed, deflation in the second exhaust pipe is terminated.

[0106] When the airbag is inflated using the second air inlet pipe, it gradually expands, causing the curved sheet to gradually move away from the second inflatable shaft 32, thereby increasing the shaft diameter of the second inflatable shaft 32 to accommodate multi-layer coils with large inner diameters. When the airbag is deflated using the second exhaust pipe, it gradually contracts, causing the curved sheet to gradually move closer to the second inflatable shaft 32, thereby decreasing the shaft diameter of the second inflatable shaft 32 to accommodate multi-layer coils with small inner diameters.

[0107] In the embodiment of the present application, automatic control of the second pneumatic shaft 32 can be achieved by ensuring that the second pneumatic shaft 32 is always connected to the second air inlet pipe and the second exhaust pipe.

[0108] The second air inlet pipe and the second air outlet pipe are both arranged at one end of the second inflation shaft 32 facing the frame 1 .

[0109] In some embodiments, the controller mounted on the frame 1 may also be provided with a third button and a fourth button. The third button can be used to control the second air inlet valve, and the fourth button can be used to control the second air outlet valve. Thus, the controller can be used to manually control the inflation and deflation of the second air shaft 32, thereby achieving rapid tensioning and unwinding of the multi-layer coil core by the second air shaft 32, thereby improving the efficiency of loading and unloading the multi-layer coil.

[0110] In some embodiments, the rewinding apparatus further includes a rotating mechanism 5. The rotating mechanism 5 is rotatably connected to the frame 1 and is located between the rewinding mechanism 3 and the frame 1. The rotating mechanism 5 is configured to abut against the multi-layer web to move the multi-layer web away from the frame 1.

[0111] It can be understood that the rotating mechanism 5 is installed between the rewinding mechanism 3 and the frame 1. When the rewinding mechanism 3 winds the multi-layer coil to form a multi-layer coil, the inner side of the multi-layer coil can abut against the rotating mechanism 5 to prevent friction between the multi-layer coil and the frame 1 during the winding process, causing wear on the inner side of the multi-layer coil, thereby ensuring the integrity of the multi-layer coil.

[0112] Among them, during the process of winding the multi-layer coil, the multi-layer coil and the rotating mechanism 5 are relatively stationary, and the rotating mechanism 5 and the frame 1 rotate relatively. The rotating mechanism 5 can be used to make rotational contact with the frame 1, thereby preventing the multi-layer coil from being damaged due to the rotational contact between the multi-layer coil and the frame 1.

[0113] like Figure 6 and Figure 7 As shown, in some embodiments, the rotating mechanism 5 includes a rotating disk 51 and a ball bearing 52. A mounting groove 511 is configured on the side of the rotating disk 51 facing the frame 1. The rotating disk 51 is configured with a through hole 512. The through hole 512 is sleeved on the rewinding mechanism 3. The ball bearing 52 is mounted in the mounting groove 511. At least a portion of the ball bearing 52 protrudes from the mounting groove 511. The protruding portion of the ball bearing 52 is configured to abut the frame 1.

[0114] It is understood that the turntable 51 is sleeved on the rewinding mechanism 3 through the through hole 512 to fix the position of the turntable 51. The mounting groove 511 constructed on the side of the turntable 51 facing the frame 1 is used to mount the ball 52, so that the ball 52 is at least partially protruding and abutting against the frame 1, thereby achieving a rotational connection between the turntable 51 and the frame 1. When the second air expansion shaft 32 of the rewinding mechanism 3 rotates to form a multi-layer coil, the turntable 51 can rotate with the second air expansion shaft 32, and the inner side of the turntable 51 can form sliding friction with the frame 1 through the ball 52. On the one hand, it can reduce frictional resistance, and on the other hand, it can prevent the multi-layer coil from contacting the frame 1, thereby protecting the multi-layer coil.

[0115] The through hole 512 may be used only to pass through the second air shaft 32 of the rewinding mechanism 3. Alternatively, the through hole 512 may be used to pass through the second driving member 31 of the rewinding mechanism 3. Alternatively, the through hole 512 may be used to pass through the bearing seat, clutch 33, etc. of the rewinding mechanism 3.

[0116] In some embodiments, a universal wheel may be provided in the mounting groove 511 , and the ball bearing 52 is mounted on the universal wheel. The universal wheel cooperates with the ball bearing 52 to achieve relative sliding between the turntable 51 and the frame 1 .

[0117] The turntable 51 can be made of an aluminum disk. A plurality of mounting grooves 511 can be provided on the side of the turntable 51 facing the frame 1, and a ball bearing 52 can be installed in each mounting groove 511. For example, the turntable 51 can have four mounting grooves 511 on the side facing the frame 1, and the four mounting grooves 511 are symmetrically distributed around the center.

[0118] In some embodiments, the turntable 51 may further be provided with weight-reducing holes, which may extend radially along the turntable 51. There may be a plurality of weight-reducing holes, which may be arranged symmetrically on the turntable 51.

[0119] like Figure 1 As shown, in some embodiments, the rewinding device further includes a roll transport mechanism 6. The roll transport mechanism 6 is mounted on the frame 1. At least one roll transport mechanism 6 is provided between each unwinding roller mechanism 2 and the rewinding mechanism 3. The roll transport mechanism 6 is configured to transport a single layer of coiled material.

[0120] It can be understood that, since the transmission distance of the single-layer coil is relatively long, the coil transport mechanism 6 can play a role in supporting the single-layer coil and ensuring the flatness of the single-layer coil.

[0121] In some embodiments, each of the winding mechanisms 6 is adjacent to the unwinding roller mechanism 2 .

[0122] like Figure 2 As shown, in some embodiments, the coiling mechanism 6 includes a coiling roller 61 and a pressure sensor 62. The coiling roller 61 is rotatably mounted on the frame 1. The pressure sensor 62 is mounted on the frame 1. The pressure sensor 62 is used to detect the coiling pressure of the single-layer coil. The pressure sensor 62 is electrically connected to the brake 22. A pressure threshold is set for the pressure sensor 62. In response to the pressure parameter detected by the pressure sensor 62 being less than the pressure threshold, the pressure sensor 62 sends a control signal to the brake 22, causing the brake 22 to increase the force applied to the single-layer coil.

[0123] It is understood that the transport roller 61 can be used to support and transport the single-layer coil. The pressure sensor 62 can monitor the pressure during the transport of the single-layer coil. When the obtained pressure parameter is less than the pressure threshold, it indicates that the tension of the single-layer coil during transport is insufficient. In this case, the brake 22 can increase the force applied to the single-layer coil to increase the tension of the single-layer coil and ensure that the single-layer coil is straight.

[0124] In response to the pressure parameter obtained by the pressure sensor 62 being less than the pressure threshold, the pressure sensor 62 can also send a control signal to the second driving member 31 to increase the output power, speed, etc. of the second driving member 31, and can also increase the tension of the single-layer coil during the transportation process.

[0125] For example, the pressure threshold may be set to 10N.

[0126] like Figure 1 As shown, in some embodiments, the rewinding device further includes a deflection correction mechanism 7. The deflection correction mechanism 7 is mounted on the frame 1. At least one deflection correction mechanism 7 is provided between each unwinding roller mechanism 2 and the rewinding mechanism 3. The deflection correction mechanism 7 is configured to correct the position of the single-layer coil.

[0127] It is understandable that the deviation correction mechanism 7 can correct the position of the single-layer coil to ensure that the single-layer coil does not deviate or shift during transmission, and to prevent defects such as wrinkles and misalignment after winding.

[0128] Each unwinding roller mechanism 2 is corrected in position by at least one deviation correcting mechanism 7 so that the position of each layer of metal sheet is correct and wrinkle-free.

[0129] like Figure 2 As shown, in some embodiments, the deflection correction mechanism 7 includes at least two parallel deflection correction rollers 71. Each deflection correction roller 71 is mounted on the frame 1. A position sensor 72 is mounted on the frame 1. The position sensor 72 is used to detect the position of the single-layer web transmitted on the deflection correction roller 71. The position sensor 72 is signal-connected to the deflection correction roller 71. The deflection correction roller 71 adjusts its position in response to the control signal.

[0130] It is understood that when a single-layer web is being conveyed on the deflection correction roller 71, the position sensor 72 monitors the position of the single-layer web. If the actual position of the single-layer web differs from the theoretical position, the deflection correction roller 71 is driven to adjust its position so that the single-layer web on the deflection correction roller 71 is positioned at the theoretical position of the deflection correction roller 71. This ensures that the single-layer web does not deviate or shift.

[0131] Because the at least two correcting rollers 71 are parallel to each other, the single-layer web is straightened by the at least two correcting rollers 71 as it travels over them, making it easier to determine the edge position of the single-layer web. Position sensor 72 determines whether the position of correcting roller 71 needs to be adjusted based on whether the edge of the single-layer web is at the theoretical position.

[0132] For example, two deflection correction rollers 71 are provided.

[0133] A stepper motor can be mounted on the frame 1, and the correcting roller 71 can be mounted at the output of the stepper motor. When the position sensor 72 detects a deviation in the position of the single-layer web, it sends a position deviation signal to the controller. In response to the position deviation signal, the controller activates the output of the stepper motor, thereby using the stepper motor to rotate the correcting roller 71 a certain angle, so that the edge of the single-layer web is in the desired position.

[0134] like Figure 1 and Figure 2 As shown, in some embodiments, the rewinding device further comprises a metering mechanism 8. The metering mechanism 8 is mounted on the frame 1. The metering mechanism 8 is used to record the winding length of the multi-layer coil.

[0135] It is understood that the metering mechanism 8 can record the winding length of the multi-layer coil so that the winding is stopped when the desired length is reached. Alternatively, when the desired length is reached, the multi-layer coil is cut and then continued to be wound to form a new roll of multi-layer coil.

[0136] In some embodiments, meter-counting mechanism 8 includes a guide wheel and a sensor mounted on the guide wheel. The multi-layer web can be driven along the outer surface of the guide wheel, thereby driving the guide wheel to rotate. The sensor can detect the number of rotations of the guide wheel. A controller receives the number of rotations of the guide wheel from the sensor and, based on the radius of the guide wheel, calculates the current length of the multi-layer web in real time.

[0137] The controllers referred to in various places in the embodiments of the present application may be the same controller. For example, each may be a touch screen. Of course, the controllers in various places in the embodiments of the present application may also be different controllers, with each controller controlling the corresponding mechanism action.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.

[0139] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0140] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.

[0141] The above are merely preferred embodiments of the present application and do not constitute any form of limitation to the present application. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
