Abstract
Description
Technical Field
[0001] This utility model relates to the field of diaphragm slitting machine technology, and in particular to a winding mechanism for a diaphragm slitting machine. Background Technology
[0002] Lithium-ion battery separators are physically soft, easily stretched, and prone to indentation. To ensure a smooth separator surface, low tension and low pressure are required during slitting. Chinese Patent Application No. CN201520646957.3 discloses a winding mechanism for a separator slitting machine, including a first support plate, a second support plate, and a transmission roller. The transmission roller is positioned between the first and second support plates. The machine also includes a winding shaft and a winding shaft mounting bracket. One end of the winding shaft mounting bracket is mounted on the first support plate via a first linear guide mechanism, and the other end is mounted on the second support plate via a second linear guide mechanism. The winding shaft is mounted on the winding shaft mounting bracket. A first photoelectric sensor is mounted on the first support plate adjacent to the transmission roller and the winding shaft, and a second photoelectric sensor is mounted on the second support plate adjacent to the transmission roller and the winding shaft.
[0003] Although the aforementioned winding mechanism can ensure that the surface of the diaphragm roll on the winding shaft and the transfer roller always maintain a certain distance, thereby preventing the diaphragm roll surface from being squeezed and allowing air between the film layers to be easily discharged, thus ensuring the winding effect, the winding roller needs to move backward from time to time during the winding process. This may cause the wound diaphragm roll to shift, affecting the winding effect. Utility Model Content
[0004] The purpose of this invention is to provide a winding mechanism for a diaphragm slitting machine, which aims to solve the problem that the winding mechanism of the existing diaphragm slitting machine is prone to causing the material roll to deviate during winding.
[0005] To achieve the above objectives, this utility model provides a winding mechanism for a diaphragm slitting machine, including a frame, a winding roller, and a transfer roller. The winding roller is mounted on the frame, and the transfer roller is mounted on the frame via a lateral movement assembly. The lateral movement assembly enables the transfer roller to move laterally on the frame. The lateral movement assembly includes a lateral movement drive, a lateral movement guide rail, and a lateral movement slide. Both the lateral movement drive and the lateral movement guide rail are mounted on the frame. The lateral movement drive is used to drive the lateral movement slide to slide on the lateral movement guide rail. A mounting seat is provided on the lateral movement slide for mounting the transfer roller. A mounting plate is provided on the side of the mounting seat near the winding roller, and a detachable detection sensor is mounted on the mounting plate for detecting the distance between the film on the winding roller and the transfer roller.
[0006] Furthermore, the frame is equipped with a roll drive and a differential gearbox. The roll is mounted on the differential gearbox via ball bearings. The differential gearbox contains a differential gear set, and the roll is equipped with a transmission gear. The transmission gear meshes with the differential gear set, and the roll drive drives the roll to rotate via the differential gear set.
[0007] Furthermore, a counterweight is provided on the side of the roll roller near the differential gearbox.
[0008] Furthermore, a clamping assembly is provided on the side of the frame away from the roll drive component. The clamping assembly is used to clamp the roll. The clamping assembly includes a lifting drive component, a lifting frame, jaws, and a clamping drive component. The lifting drive component is mounted on the frame and is used to drive the lifting frame to rise or fall. A slide is provided on the lifting frame, and the jaws can slide on the slide. A clamping drive component is installed on the slide and is used to drive the jaws to move closer together.
[0009] Furthermore, a limit rod is installed on the frame to limit the raising or lowering of the lifting frame.
[0010] Furthermore, the coil roller includes a roller body, connecting shafts, adjusting screws, connecting blocks, rocker arms, and support rods. A set of connecting shafts is provided at both ends of the roller body. A transmission gear is installed on one side of the connecting shaft, and a ball bearing for clamping by chucks is installed on the other side. The adjusting screw is installed in the roller body, with the threads at both ends rotating in opposite directions. The connecting block is installed on the roller body, and the adjusting screw controls the sliding of the connecting block on the roller body. The connecting block is connected to multiple sets of rocker arms via rotating shafts, and the rocker arms are connected to the support rods via rotating shafts.
[0011] Furthermore, the connecting block is provided with at least three sets of support rods, which are evenly distributed around the periphery of the connecting block. Each set of support rods is connected to the connecting block through at least two parallel swing rods.
[0012] Furthermore, a handle is installed at one end of the adjusting screw.
[0013] Furthermore, the frame is equipped with multiple sets of limit switches, which are installed on both sides of the transverse guide rail. The limit switches are used to limit the movement range of the transverse slide.
[0014] The winding mechanism of the diaphragm slitting machine provided by this utility model, compared with the prior art, allows the winding roller to be relatively stationary on the frame during winding. When the film on the winding roller reaches a certain thickness, the detection sensor is triggered, and the transverse drive controls the transverse slide to move backward, controlling the distance between the winding roller and the transfer roller. When the material roll on the winding roller reaches a certain thickness and needs to be unloaded, after the winding roller stops, the clamping drive drives the chuck to open, and then the lifting drive drives the lifting frame to lower the chuck. The user only needs to turn the handle to retract the support rod for easy unloading. Attached Figure Description

[0034] The present invention will be described in detail below with reference to specific embodiments.
[0035] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.
[0036] like Figures 1 to 10 As shown, this utility model provides a winding mechanism for a diaphragm slitting machine, including a frame 1, a winding roller 3, and a transfer roller 2. The winding roller 3 is mounted on the frame 1, and the transfer roller 2 is mounted on the frame 1 via a transverse component 4. The transverse component 4 enables the transfer roller 2 to move transversely on the frame 1. The transverse component 4 includes a transverse drive 45, a transverse guide rail 44, and a transverse slide 40. Both the transverse drive 45 and the transverse guide rail 44 are mounted on the frame 1. The transverse drive 45 drives the transverse slide 40 to slide on the transverse guide rail 44. A mounting seat 41 is provided on the transverse slide 40 for mounting the transfer roller 2. A mounting plate 42 is provided on the side of the mounting seat 41 near the winding roller 3. A detachable detection sensor 43 is mounted on the mounting plate 42 for detecting the distance between the film on the winding roller 3 and the transfer roller 2.
[0037] In this embodiment, the detection sensor 43 is preferably a laser photoelectric sensor, which is mounted on the mounting plate 42 by screws.
[0038] In this embodiment, the transverse drive 45 is preferably a stepper motor, a synchronous belt and a synchronous pulley, which enable the transverse slide 40 to translate on the frame 1.
[0039] With the above design scheme, during the winding process, the film is guided by the transfer roller 2 and wound onto the winding roller 3. When the diameter of the film roll on the winding roller 3 reaches a certain thickness, the detection sensor 43 is triggered. After receiving the signal, the lateral drive 45 rotates a certain distance, causing the transfer roller 2 to move backward a certain distance. This process is repeated to ensure that the distance between the transfer roller 2 and the film roll is always maintained within a certain range, thereby ensuring that the diaphragm surface is not squeezed. At the same time, during the winding process, the central axis of the winding roller 3 is always in a relatively stationary state on the frame 1, reducing the offset that occurs during the winding process.
[0040] In this embodiment, a winding drive unit 5 and a differential gearbox 6 are provided on the frame 1. The winding roller 3 is mounted on the differential gearbox 6 through ball bearings 37. A differential gear set is provided in the differential gearbox 6. A transmission gear 36 is provided on the winding roller 3. The transmission gear 36 meshes with the differential gear set. The winding drive unit 5 drives the winding roller 3 to rotate through the differential gear set.
[0041] With the above design, the ball bearing 37 enables the roll 3 to rotate on the differential gearbox 6, while the roll drive 5 drives the roll 3 to rotate, ensuring that the roll 3 can wind up the film.
[0042] In this embodiment, a counterweight 38 is provided on the side of the winding roller 3 near the differential box 6. The counterweight 38 can adjust the center of gravity of the winding roller 3 so that the center of gravity of the winding roller 3 is in the differential box 6, so that the central axis of the winding roller 3 is always parallel to the central axis of the transfer roller 2, thereby reducing the offset of the film during winding.
[0043] In this embodiment, a clamping assembly 7 is provided on the side of the frame 1 away from the roll drive 5. The clamping assembly 7 is used to clamp the roll 3. The clamping assembly 7 includes a lifting drive 70, a lifting frame 71, a jaw 74, and a clamping drive 73. The lifting drive 70 is mounted on the frame 1 and is used to drive the lifting frame 71 to rise or fall. A slide 72 is provided on the lifting frame 71. The jaw 74 can slide on the slide 72. The clamping drive 73 is installed on the slide 72 and is used to drive the jaw 74 to move closer together.
[0044] In this embodiment, a limiting light rod 75 is provided on the frame 1, which is used to limit the raising or lowering of the lifting frame 71.
[0045] Through the above design scheme, the clamping component 7 can clamp the end of the winding roller 3 away from the differential box 6, so as to prevent the center of gravity of the winding roller 3 from changing after the film is wound on, which would cause the winding roller 3 to deviate. In this embodiment, when the winding operation is required, the operator needs to put the paper tube for winding on the winding roller 3. Then the lifting drive component 70 drives the lifting frame 71 to rise until the winding roller 3 enters the clamping range of the chuck 74. The chuck 74 clamps the other end of the winding roller 3 under the drive of the clamping drive component 73, providing support for the winding roller 3 and ensuring that the central axis of the winding roller 3 is always parallel to the central axis of the transmission roller 2.
[0046] When it is necessary to remove the paper tube fully rolled with film from the winding roller 3, after the winding roller 3 stops rotating, the clamping drive 73 drives the chuck 74 to open to both sides, releasing the restriction of the winding roller 3. Then, the lifting drive 70 drives the lifting frame 71 to descend, storing the chuck 74 in the frame 1 to avoid interfering with the subsequent unloading work and to facilitate the staff to remove the paper tube from one side of the clamping assembly 7.
[0047] In this embodiment, the roll 3 includes a roller body 30, a connecting shaft 31, an adjusting screw 33, a connecting block 32, a rocker arm 34, and a support rod 35. A set of connecting shafts 31 is provided at both ends of the roller body 30. A transmission gear 36 is provided on one side of the connecting shaft 31, and a ball bearing 37 for clamping by a chuck 74 is installed on the other side of the connecting shaft 31. The adjusting screw 33 is installed in the roller body 30, and the threads at both ends of the adjusting screw 33 rotate in opposite directions. The connecting block 32 is installed on the roller body 30, and the adjusting screw 33 is used to control the sliding of the connecting block 32 on the roller body 30. The connecting block 32 is connected to multiple sets of rocker arms 34 via a rotating shaft, and the rocker arms 34 are connected to the support rod 35 via a rotating shaft.
[0048] With the above design, before winding, the operator can place the paper tube onto the winding roller 3 from the side without the transmission gear 36. Then, by rotating the adjusting screw 33, the opposite thread direction can bring the connecting blocks 32 at both ends of the roller body 30 closer together. Under the action of the swing rod 34, the connecting blocks 32 that are close together can move the support rod 35 away from the roller body 30, clamping the paper tube onto the winding roller 3 from the inside out, ensuring that the winding roller 3 can wind up the film. When it is necessary to remove the roll, the operator rotates the adjusting screw 33 in the opposite direction to move the connecting blocks 32 away from each other. The moving connecting blocks 32, through the swing rod 34, drive the support rod 35 closer to the roller body 30, making it convenient for the operator to remove the paper tube with the film.
[0049] In this embodiment, at least three sets of support rods 35 are provided on the connecting block 32. The three sets of support rods 35 are evenly distributed around the periphery of the connecting block 32, and each set of support rods 35 is connected to the connecting block 32 through at least two parallel swing rods 34.
[0050] Through the above design scheme, the connecting block 32 can simultaneously cause multiple sets of support rods 35 to expand outward or retract inward, ensuring that the central axis of the paper tube can coincide with the central axis of the winding roller 3.
[0051] In this embodiment, a handle 39 is installed at one end of the adjusting screw 33. The handle 39 can easily adjust the rotation of the screw 33, making it convenient for the user to lock or loosen the paper tube.
[0052] In this embodiment, the frame 1 is provided with multiple sets of limit switches, which are installed on both sides of the transverse guide rail 44. The limit switches are used to limit the movement range of the transverse slide 40.
[0053] The winding mechanism of the diaphragm slitting machine provided by this utility model, compared with the prior art, allows the winding roller 3 to be relatively stationary on the frame 1 during winding. When the film on the winding roller 3 reaches a certain thickness, the detection sensor 43 is triggered, and the transverse drive 45 controls the transverse slide 40 to move backward, controlling the distance between the winding roller 3 and the transmission roller 2. When the material roll on the winding roller 3 reaches a certain thickness and needs to be unloaded, after the winding roller 3 stops, the clamping drive 73 drives the chuck 74 to open, and then the lifting drive 70 drives the lifting frame 71 to lower the chuck 74. The user only needs to turn the handle 39 to retract the support rod 35 for easy unloading.
[0054] Where there is no conflict, the above embodiments and features can be combined with each other.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
