Description

Technical Field

[0001] This utility model relates to the field of foil processing equipment, and more specifically, to a winding and changing mechanism and a slitting machine. Background Technology

[0002] During the slitting process of the electrode sheets after roll forming, there are two methods for splicing the tape: automatic roll changing and manual splicing. Conventional automatic splicing uses a turret type, which requires a large amount of equipment space. In order to reduce the factory space required by the equipment, some equipment adopts a dual-station automatic roll changing system that does not rely on a turret mechanism. Although this is a change in layout from the turret type, it still occupies a large amount of space, and the workstations are not concentrated enough when manually operating the loading and unloading, which affects the production efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a winding and changing mechanism and a slitting machine to solve the problem that the winding and changing mechanism in the prior art has a large space requirement.

[0004] To achieve the above objectives, according to one aspect of the present invention, a winding and changing mechanism is provided, including a frame, multiple winding shafts, a pushing assembly, and a cutting assembly. The winding shafts are rotatably connected to the frame and are capable of winding foil. The pushing assembly is movably disposed from the frame, and the pushing end position of the pushing assembly is switchable and can cooperate with different winding shafts to push the material on different winding shafts out. The cutting assembly is connected to the frame and is capable of cutting the foil.

[0005] Furthermore, at least a portion of the pusher assembly is rotatably connected to the frame, the pusher end has multiple pusher stations, the pusher stations are arranged circumferentially along the rotation axis of the pusher assembly, and each take-up shaft is distributed circumferentially along the pusher assembly and located at the pusher station.

[0006] Furthermore, the feeding assembly includes a feeding component, a rotary drive component, and a feeding drive component. The feeding component is rotatably disposed relative to the frame and can move axially along the take-up shaft. The feeding component has a feeding end. The rotary drive component is drivenly connected to the feeding component and drives the feeding component to rotate to switch different feeding positions. The feeding drive component is connected to the rotary drive component and drives the rotary drive component and the feeding component to move synchronously along the take-up shaft.

[0007] Furthermore, the take-up shafts are arranged in groups, with the take-up shafts in the same group arranged along the first direction. The take-up and change mechanism also includes a first driving member and a second driving member. Both the first driving member and the second driving member are drivenly connected to the cutting component. The first driving member drives the cutting component to move along the first direction, and the second driving member drives the cutting component to move along a second direction that forms an angle with the first direction.

[0008] Furthermore, the cutting assembly includes a movable frame, a rubber roller, and a cutter for cutting foil. The movable frame is movably disposed from the frame body; the rubber roller is movably connected to the movable frame, and the direction of movement of the rubber roller relative to the movable frame forms an angle with the direction of movement of the movable frame relative to the frame body. When switching the take-up shaft, the rubber roller approaches the take-up shaft of the foil to be wound and adheres the foil to the take-up shaft; the cutter is connected to the movable frame and cuts the foil adhered to the take-up shaft.

[0009] Furthermore, there are multiple rubber rollers and cutters, and the rubber rollers and cutters are arranged in corresponding groups, with different groups of rubber rollers and cutters cooperating with different take-up shafts.

[0010] Furthermore, the winding and changing mechanism also includes a support assembly, which is movably configured with respect to the frame and has a support position supporting the winding shaft below and a clearance position avoiding the area around the winding shaft.

[0011] Furthermore, the support assembly includes a support arm, a support drive component, and a limiting component. The support arm is rotatably connected to the frame and has a support portion that can be sleeved on the bottom outer side of the take-up shaft. The support drive component is driven to the support arm and drives the support arm to rotate. The limiting component is connected to the frame and limits the stroke of the support drive component.

[0012] Furthermore, the support assembly also includes a connecting rod, the two ends of which are rotatably connected to the support drive and the support arm, respectively. The connecting rod forms a first connection point with the support part, and the support arm forms a second connection point with the frame. The first connection point and the second connection point are located at different positions of the support arm. The support drive is driven to the support arm through the connecting rod. When the support assembly is in the support position, the length direction of the connecting rod is perpendicular to the movement direction of the support drive.

[0013] According to another aspect of the present invention, a slitting machine is provided, including the above-described winding and changing mechanism.

[0014] By applying the technical solution of this utility model, the position of the pusher end can be switched, allowing the pusher component to cooperate with different take-up shafts. This enables one pusher end to cooperate with multiple take-up shafts to push the material off multiple take-up shafts. As a result, the take-up and roll-changing mechanism does not need to match a pusher end for each take-up shaft, thereby reducing the space requirements of the take-up and roll-changing mechanism and reducing costs. Specifically, to improve winding efficiency, the winding and changing mechanism is equipped with multiple winding shafts. When one winding shaft is full, the foil is cut by the cutting component, and the mechanism switches to another winding shaft to continue winding. At this time, the pusher end switches to the full winding shaft and pushes the foil off the winding shaft. When another winding shaft is full, the pusher end can switch to the other winding shaft and push the foil off the other winding shaft. In this way, the movable setting of the pusher component allows the pusher end to switch to any winding shaft and push the foil off the winding shaft. This allows multiple winding shafts to share a single pusher component, thereby reducing the space occupied by the winding and changing mechanism and making the structure of the winding and changing mechanism more compact.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] To address the issue of large space requirements in existing winding and changing mechanisms, this utility model provides a winding and changing mechanism and a slitting machine, wherein the slitting machine includes the winding and changing mechanism described below.

[0026] like Figures 1 to 4 The shown is a winding and changing mechanism, including a frame 10, a plurality of winding shafts 20, a pushing assembly 30, and a cutting assembly 40. The winding shafts 20 are rotatably connected to the frame 10 and are capable of winding foil. The pushing assembly 30 is movably arranged to the frame 10, and the pushing end position of the pushing assembly 30 can be switched and can cooperate with different winding shafts 20 to push the material on different winding shafts 20 out. The cutting assembly 40 is connected to the frame 10 and is capable of cutting the foil.

[0027] This embodiment allows the pusher end position to be switchably configured, enabling the pusher assembly 30 to cooperate with different take-up shafts 20. This allows one pusher end to cooperate with multiple take-up shafts 20 to push the material off multiple take-up shafts 20. As a result, the take-up and roll-changing mechanism does not need to match a pusher end for each take-up shaft 20, thereby reducing the space requirements of the take-up and roll-changing mechanism and reducing costs. Specifically, to improve winding efficiency, the winding and changing mechanism is equipped with multiple winding shafts 20. When one winding shaft 20 is full, the foil is cut by the cutting component 40, and the mechanism switches to another winding shaft 20 to continue winding. At this time, the pusher end switches to the full winding shaft 20 and pushes the foil out of the winding shaft 20. When another winding shaft 20 is full, the pusher end can switch to the other winding shaft 20 and push the foil out of the other winding shaft 20. In this way, the movable setting of the pusher component 30 allows the pusher end to switch to any winding shaft 20 and push the foil out of the winding shaft 20, so that multiple winding shafts 20 can share a single pusher component 30, thereby reducing the space occupied by the winding and changing mechanism and making the structure of the winding and changing mechanism more compact.

[0028] In this embodiment, at least a portion of the pusher assembly 30 is rotatably connected to the frame 10. The pusher end has multiple pusher stations arranged circumferentially along the rotation axis of the pusher assembly 30. Each take-up shaft 20 is distributed circumferentially along the pusher assembly 30 and located at a pusher station, thereby enabling the pusher end to switch to different pusher stations to achieve foil feeding from different take-up shafts 20. Specifically, this embodiment has four take-up shafts 20, therefore the pusher end has four pusher stations. The pusher end is rotatably configured relative to the frame 10, thereby enabling it to switch to different pusher stations. When the pusher end is switched to a certain pusher station, it can push the foil on the take-up shaft 20 located at the pusher station to realize the foil feeding. In this way, when the foil on the take-up shaft 20 needs to be fed, it is only necessary to switch the pusher end to the corresponding pusher station to push the foil. The switching is convenient and easy to operate, so that one pusher component 30 can be used with multiple take-up shafts 20, thereby saving the space occupied by the pusher component 30, which is conducive to simplifying the structure of the take-up and change mechanism, thereby reducing the space occupied by the take-up and change mechanism.

[0029] like Figure 3As shown, in this embodiment, the feeding assembly 30 includes a feeding component 31, a rotation drive component 32, and a feeding drive component 33. The feeding component 31 is rotatably disposed relative to the frame 10 and can move along the axial direction of the take-up shaft 20. The feeding component 31 has a feeding end. The rotation drive component 32 is drivenly connected to the feeding component 31 and drives the feeding component 31 to rotate to switch different feeding positions. The feeding drive component 33 is connected to the rotation drive component 32 and drives the rotation drive component 32 and the feeding component 31 to move synchronously along the axial direction of the take-up shaft 20. Specifically, in this embodiment, the feeding drive component 33 is connected to the frame 10, and the output end of the feeding drive component 33 is movable relative to the frame 10. The rotation drive component 32 is connected to the output end of the feeding drive component 33. Optionally, the feeding drive component 33 can be a cylinder; the rotation drive component 32 can be a servo motor. The pusher 31 is a rectangular plate, with its length perpendicular to the moving direction of the pusher drive 33. The first end of the pusher 31 is connected to the rotary drive 32, and this first end is the rotation center of the pusher 31. The second end of the pusher plate can contact the foil on the take-up roll and push the foil off the take-up roll. Thus, with the parameters set, when the take-up shaft 20 needs to unload, the rotary drive 32 drives the drive plate to rotate to the set position, causing the pusher 31 to move to the corresponding pusher station. Then, the output end of the pusher drive 33 drives the rotary drive 32 and the pusher plate to move synchronously along the axial direction of the take-up shaft 20, thereby unloading the foil from the take-up shaft 20 along its axial direction. Of course, the pusher drive 33 can also adopt other structural forms, such as a motor and lead screw combination to drive the pusher 31 to move along the axial direction of the take-up shaft 20.

[0030] Preferably, the pusher assembly 30 can be provided with a guide member 34. The guide member 34 is long and cylindrical, and its length direction is consistent with the movement direction of the output end of the pusher drive member 33. The guide member 34 can be set on the frame 10 and pass through the output end of the pusher drive member 33, so that when the output end of the pusher drive member 33 extends along the axial direction of the take-up roll, the guide member 34 can play a guiding role, thereby ensuring the stability and reliability of the pusher drive member 33 driving the pusher member 31. The rotating drive member 32 is provided with a connecting end connected to the pusher drive member 33 on the side away from the pusher member 31. The rotating drive member 32 is connected to the output end through the connecting end. The connecting end includes a connecting rod and a connecting plate. The connecting rod is also long and cylindrical, and its length direction is consistent with the length direction of the guide member 34. The connecting plate is set at the end of the connecting rod away from the pusher member. The connecting plate is provided with a through hole for the guide member 34 to pass through, and the position of the connecting rod should avoid interference with the through hole. In this way, the smoothness and reliability of the pusher assembly 30's movement are ensured, and the axial movement of the pusher 31 along the take-up shaft 20 and the rotation of the pusher 31 do not interfere with each other.

[0031] Preferably, the pusher assembly 30 is further provided with a speed reducer. One end of the pusher 31 is connected to the rotary drive 32 through the speed reducer and rotates under the drive of the rotary drive 32, thereby improving the accuracy and smoothness of the pusher 31's movement. Optionally, the speed reducer can be a worm gear reducer.

[0032] In this embodiment, the take-up shafts 20 are arranged in groups, with the take-up shafts 20 within the same group arranged along a first direction. The take-up and change mechanism also includes a first drive member 50 and a second drive member 60. Both the first drive member 50 and the second drive member 60 are drivenly connected to the cutting assembly 40. The first drive member 50 drives the cutting assembly 40 to move along the first direction, and the second drive member 60 drives the cutting assembly 40 to move along a second direction forming an angle with the first direction. This allows the cutting assembly 40 to move along the first direction to switch to different take-up shafts 20 for cutting the foil, and also to move along the second direction to bring the cutting assembly 40 closer to the foil for cutting. Specifically, in this embodiment, the take-up shafts 20 are arranged in pairs, spaced apart along the first direction. The frame 10 is provided with a first guide rail extending along the first direction and a second guide rail extending along the second direction. The second guide rail is fixed to the frame 10, and the first guide rail is movably connected to the frame 10 through the second guide rail. The first guide rail is located on one side of the take-up shaft 20, and multiple second guide rails are provided. The first guide rail can move relative to the second guide rails along a second direction. To maintain the stability of the first guide rail's movement along the second guide rails, multiple second guide rails can be provided. Thus, the first driving member 50 can drive the cutting component 40 to move along the first direction, and the second driving member 60 can drive the first guide rail to move along the second guide rail, causing the cutting component 40 to move along the second direction. In this way, when the first driving member 50 drives the cutting component 40 to move along the first guide rail, the cutting component 40 can switch positions between different take-up shafts 20 within the same group. When the second driving member 60 drives the first guide rail to move along the second guide rail, the cutting component 40 moves closer to or further away from the foil along the second direction to cut the foil. Optionally, the first driving component 50 can be a servo motor, which drives the cutting assembly 40 to move along the first direction via a right-angle commutator; the second driving component 60 can be a push cylinder, which is located on the side of the cutting assembly 40 away from the first guide rail, and drives the cutting assembly 40 to move along the second direction by pushing or pulling the first guide rail. Of course, the movement of the cutting assembly 40 along the first and second directions can also be achieved using other structural forms, such as using a servo motor to drive a gear and rack structure to drive the movement of the cutting assembly 40.

[0033] In this embodiment, in order to facilitate the quick movement of the cutting component 40 to the target position, the first direction is set perpendicular to the second direction.

[0034] In this embodiment, the cutting assembly 40 includes a movable frame 41, a rubber roller 42, and a cutter 43 for cutting foil. The movable frame 41 is movably disposed with respect to the frame 10. The rubber roller 42 is movably connected to the movable frame 41, and the moving direction of the rubber roller 42 relative to the movable frame 41 forms an angle with the moving direction of the movable frame 41 relative to the frame 10. When switching the take-up shaft 20, the rubber roller 42 approaches the take-up shaft 20 to which the foil is to be wound and adheres the foil to the take-up shaft 20. The cutter 43 is connected to the movable frame 41 and cuts the foil adhered to the take-up shaft 20. Specifically, in this embodiment, the connection between the first drive member 50 and the second drive member 60 and the cutting assembly 40 is achieved through the movable frame 41. The movable frame 41 is movably disposed with respect to the first guide rail. The movable frame 41 is configured as a plate-like structure, and both the rubber roller 42 and the cutter 43 are movably disposed on the movable frame 41. The extension direction of the rubber roller 42 and the extension direction of the cutter 43 are neither along the first direction nor the second direction, but are both set towards the take-up shaft 20 to which the foil is to be wound, so as to facilitate the close proximity to the take-up shaft 20 to adhere the foil to the empty roll and cut the foil. The cutting assembly 40 in this embodiment also includes a rubber roller 42 driver and a cutter 43 driver, both of which are mounted on the moving frame 41. When the cutting assembly 40 moves into position, the rubber roller 42 driver drives the rubber roller 42 to extend, and after confirming that the double-sided adhesive on the foil and the take-up shaft 20 is adhered, the cutter 43 driver drives the cutter 43 to extend and cut the foil, thereby realizing automatic roll changing of the take-up shaft 20 in the same group.

[0035] It should be noted that during the movement of the moving frame 41 along the first direction, the tension of the foil is detected by the tension roller, and the friction force is adjusted by the electro-proportional valve of the take-up shaft 20 to adjust the tension in real time, ensuring that no abnormal problems such as barrel splitting, slippage, or tape breakage occur during winding. Optionally, the take-up shaft 20 adopts a slip shaft, which can be driven by an independent servo motor and a planetary reducer to ensure that the speed of each take-up shaft 20 is uniform, and a dual-air-path closed-loop tension control is adopted.

[0036] In this embodiment, there are multiple rubber rollers 42 and cutters 43, and the rubber rollers 42 and cutters 43 are arranged in corresponding groups. Different groups of rubber rollers 42 and cutters 43 cooperate with different take-up shafts 20, so that one cutting component 40 can cooperate with each take-up shaft 20 in the same group to achieve automatic roll changing, without having to set a cutting component 40 for each take-up shaft 20, thereby saving the space occupied by the take-up and roll changing mechanism. Specifically, the movable frame 41 in this embodiment is provided with two rubber rollers 42 and two cutters 43, that is, one movable frame 41 is provided with two groups of rubber rollers 42 and cutters 43, and each group of rubber rollers 42 and cutters 43 is corresponding to the pasting and cutting of foil material on one take-up shaft 20. The two groups of rubber rollers 42 and cutters 43 are symmetrically arranged, with the axis of symmetry along the second direction, and the two rubber rollers 42 are arranged adjacent to each other, and the two cutters 43 are arranged on the side of the two rubber rollers 42 that are far away from each other. When the moving frame 41 moves to a position close to the take-up shaft 20 of the foil to be wound, the corresponding rubber roller 42 extends to stick the foil onto the empty roll. After sticking, the cutter 43 in the same group extends to cut the foil, thus completing this automatic roll change. When the take-up shaft 20 is full, the first drive 50 and the second drive 60 drive the moving frame 41 to a position close to another take-up shaft 20 in the same group. The rubber roller 42 and cutter 43 of the other group repeat the same action to complete the automatic roll change. In this way, the cutting component 40 that cooperates with the take-up shaft 20 in the same group is integrated into the same moving frame 41, which has a compact structure and is easy to operate. The cutting component 40 reciprocates along the first direction, thereby further saving the space occupied by the take-up and roll change mechanism.

[0037] like Figure 4 As shown, in this embodiment, the winding and changing mechanism further includes a support component 70. The support component 70 is movably configured with the frame 10 and has a support position supporting the winding shaft 20 below it and a clearance position avoiding the periphery of the winding shaft 20. This allows it to both support the winding shaft 20 to prevent deformation and to avoid affecting the feeding of the foil by the feeding component 30. Specifically, the support component 70 is located on one side of the winding shaft 20, and each winding shaft 20 has a corresponding support component 70. When the support component 70 is in the support position, it is close to the winding shaft 20, providing support and preventing the winding shaft 20 from bending and deforming due to its weight as the foil winds around, thus affecting production accuracy. When the winding shaft 20 is full and the feeding component 30 unloads the foil from the winding shaft 20, the support component 70 avoids the periphery of the winding shaft 20, allowing the foil to move axially along the winding shaft 20 and smoothly exit from one end of the winding shaft 20. In this embodiment, one end of the take-up shaft 20 is connected to the frame 10, and the support assembly 70 is disposed at the end of the take-up shaft 20 away from the frame 10 to support the take-up shaft 20. Of course, depending on the actual situation, multiple support assemblies 70 may be provided along the axial direction of the take-up shaft 20 to further ensure the safety and stability of the take-up shaft 20.

[0038] In this embodiment, the support assembly 70 includes a support arm 71, a support drive member 72, and a limiting member 73. The support arm 71 is rotatably connected to the frame 10, and the support arm 71 has a support portion 711, which can be sleeved on the bottom outer side of the take-up shaft 20. The support drive member 72 is drivenly connected to the support arm 71 and drives the support arm 71 to rotate. The limiting member 73 is connected to the frame 10 and limits the stroke of the support drive member 72. Specifically, the support portion 711 in this embodiment is provided with a first rotating hole and a second rotating hole. The first rotating hole is located between the two ends of the support arm 71, and the support drive member 72 is rotatably connected to the support arm 71 through the first rotating hole. One end of the support arm 71 is connected to the frame 10 through the second rotating hole to realize the rotation of the support arm 71 and the frame 10; the other end is provided with the support portion 711 to support the take-up shaft 20. Considering the large movement space along the first direction in this embodiment, which minimizes interference with other components, the support drive member 72 is positioned on the side of the support arm 71 away from the take-up shaft 20 and moves along the first direction to reduce the space occupied by the take-up and rewinding mechanism. Of course, depending on the actual situation, the support drive member 72 can also be configured to move in other directions, and the positional relationship between the support drive member 72 and the support arm 71 can be adjusted accordingly. In this way, the movement of the support drive member 72 along the first direction drives the rotation of the support arm 71, allowing the support drive member 72 to move the first rotating hole away from the take-up shaft 20, thereby moving the support arm 71 away from the take-up shaft 20 to avoid other components. It also allows the support drive member 72 to move the first rotating hole closer to the take-up shaft 20, so that the support arm 71 is fitted onto the outside of the take-up shaft 20 to support it, thus achieving both avoidance and support of the support assembly 70.

[0039] In this embodiment, two limiting members 73 are provided, including a first limiting member and a second limiting member. The limiting member 73 is a bolt and nut structure, with the nut fixed to the frame 10 and the bolt and nut threadedly connected.

[0040] When the nut rotates, the bolt of the first limiting member can simultaneously move along the first direction. When the support drive member 72 drives the support arm 71 to move closer to the take-up shaft 20 and the support part 711 is just sleeved on the outside of the take-up shaft 20, the first limiting member abuts against the moving end of the support drive member 72, thereby limiting the movement stroke of the support drive member 72 and preventing the support part 711 from moving excessively and causing the take-up shaft 20 to be deformed due to force. When the position of the support assembly 70 supporting the take-up shaft 20 is adjusted, the limiting position of the moving end of the support drive member 72 can also be adjusted by rotating the bolt of the first limiting member. The moving end of the support drive member 72 refers to the part of the support drive member 72 that moves relative to the frame 10 along the first direction and drives the support part 711 to rotate. Optionally, a limiting hole can be provided at the end of the moving end near the first limiting member. The bolt of the first limiting member at the end near the moving end serves as a limiting part. When the moving end moves along the first direction to abut against the first limiting member, the bolt of the first limiting member at the end near the moving end passes into the limiting hole to further limit the movement and provide support force when the support part 711 is sleeved on the outside of the take-up shaft 20. The second limiting member is arranged perpendicularly to the first limiting member and is located on the side of the support drive member 72 near the support arm 71. When the support drive member 72 extends and drives the support part 711 away from the take-up shaft 20 and closer to the support drive member 72, the second limiting member abuts against the support part 711, thereby indicating that the support drive member has moved into place and preventing the support part 711 from continuing to move and causing collision damage to the support drive member 72.

[0041] In this embodiment, the support assembly 70 further includes a connecting rod 74. The two ends of the connecting rod 74 are rotatably connected to the support drive member 72 and the support arm 71, respectively. The connecting rod 74 forms a first connection point with the support portion 711, and the support arm 71 forms a second connection point with the frame 10. The first and second connection points are located at different positions on the support arm 71. The support drive member 72 is drivenly connected to the support arm 71 via the connecting rod 74. When the support assembly 70 is in the support position, the length direction of the connecting rod 74 is perpendicular to the moving direction of the support drive member 72. Specifically, the support drive member 72 in this embodiment has a moving end connected to the connecting rod 74. The frame 10 is provided with a third guide rail extending along a first direction. The moving end can slide along the extending direction of the third guide rail. The side of the moving end closest to the take-up shaft 20 is rotatably connected to the connecting rod 74. The first connection point, also known as the first rotating hole, is located between the two ends of the support arm 71; the second connection point, also known as the second rotating hole, is located at the end of the support arm 71 away from the support part 711. Thus, the two ends of the connecting rod 74 are rotatably connected to the moving end and the second connection point, respectively. The connecting rod 74 is designed so that when the cylinder retracts, the moving end abuts against the limiting member 73, and the support drive member 72 drives the support assembly 70 to be sleeved on the outside of the take-up shaft 20. The connecting rod 74 is perpendicular to the first direction, forming a dead point. This ensures that when the support arm 71 supports the take-up shaft 20, the supporting force acts on the dead point, i.e., the limiting member 73, instead of the support drive member 72, thereby avoiding continuous stress on the support drive member 72 and ensuring the service life of the support drive member 72 and the stability of the support arm 71.

[0042] It should be noted that, for ease of explanation, this embodiment uses the example of the first direction being the up-down direction and the second direction being the left-right direction. However, the first and second directions are not limited to these and can be set to other directions. The coil refers to the winding device sleeved on the outside of the take-up shaft 20.

[0043] like Figure 1 , Figure 2As shown, the structure of the winding and unwinding mechanism in this embodiment is as follows: Two sets of winding shafts 20 are provided, symmetrically arranged left and right. The winding shafts 20 within the same set are arranged vertically. A cutting component 40 is provided on each side of the two sets of winding shafts 20, i.e., on the left and right sides of the winding and unwinding mechanism. A pushing component 30 is provided in the middle position of the two sets of winding shafts 20. Of course, the number of sets of winding shafts 20 and the number of winding shafts 20 within the same set can be adjusted according to actual conditions, and the movement of the cutting component 40 and the pushing component 30 can be adjusted accordingly. Compared to conventional turret-type separate winding, the winding and unwinding mechanism in this embodiment occupies less space and eliminates the turret-type geared motor. This structural change makes the winding and unwinding mechanism in this embodiment more energy-efficient. This four-axis centralized arrangement structure is more convenient for personnel to operate and also has the advantage of being lightweight, reducing the required materials and equipment weight. It should be noted that, to avoid obstructing other components, Figure 2 The structure of the pusher assembly 30 is not shown in the image. For details on the structure of the pusher assembly 30, please refer to [link / reference]. Figure 3 .

[0044] The movement process of the winding and unwinding mechanism in this embodiment is as follows: The first driving member 50 drives the moving frame 41 to move along the first direction. The required lifting height of the moving frame 41 is set. When it is necessary to switch to the upper winding shaft 20, the moving frame 41 moves upward. When it is necessary to switch to the lower winding shaft 20, the moving frame 41 moves downward. After reaching the designated position, the cutting component 40 is still a certain distance from the winding shaft 20 in the lateral direction. The lateral movement is achieved by the moving frame 41 and the first guide rail moving laterally along the second guide rail. After setting the lateral movement distance, the second driving member 60 slowly pulls the first guide rail and synchronously drives the glue roller 42 until it stops when the glue roller 42 presses on the empty roll. Under the control of the PLC programmable logic controller, the empty roll with tape is rotated to the designated position. At this time, the glue roller 42 driving member pushes the glue roller 42 to extend. After confirming that the foil and the double-sided tape on the roll are adhered, the cutter 43 cuts the foil to be replaced, thus achieving automatic roll changing. The automatic winding mechanism switches between the upper and lower take-up shafts 20. When the upper take-up shaft 20 cuts material to the lower take-up shaft 20, the upper and lower rubber rollers 42 and the lower cutter 43 of the cutting assembly work. When the lower take-up shaft 20 cuts material to the upper take-up shaft 20, the upper rubber roller 42 and the upper cutter 43 work. During normal production, the first drive component 50 drives the moving frame 41 to be positioned between the upper and lower take-up shafts 20 to save space and avoid other moving parts. During normal production, the support component 70 retracts the support drive component 72, and the moving end abuts against the limiting component 73. With the coordinated action of the connecting rod 74 and the support arm 71, the support arm 71 can be brought close to the take-up shaft 20 to provide support. During unloading, the support drive component 72 extends upward, and the connecting rod 74 drives the support arm 71 to rotate, without obstructing the space required for unloading. When the pushing mechanism is working, the pushing drive component 33 pushes out the pushing component 31 and the rotation drive component 32 as a whole.

[0045] It should be noted that "multiple" in the above embodiments refers to at least two.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0047] 1. This solves the problem of large space requirements in existing winding and changing mechanisms;

[0048] 2. By setting the pusher end position to be switchable, the pusher component can be matched with different take-up shafts, so that one pusher end can be matched with multiple take-up shafts to push the material on multiple take-up shafts out. This eliminates the need for the take-up and roll changing mechanism to match a pusher end for each take-up shaft, thereby reducing the space requirements of the take-up and roll changing mechanism and reducing costs.

[0049] 3. The movable setting of the pusher component allows the pusher end to be switched to any take-up shaft and push the foil off the take-up shaft, so that multiple take-up shafts can share a single pusher component, thereby reducing the space occupied by the take-up and roll-changing mechanism and making the structure of the take-up and roll-changing mechanism more compact.
