Technical Field
[0001] This utility model relates to the field of thin film production technology, specifically an automatic winding device for capacitor film production. Background Technology
[0002] Traditional methods rely on the number of motor rotations to observe the winding thickness and determine whether winding is complete. However, under different frictional conditions, this method can cause the film to shrink inward, preventing the desired number of rotations from being achieved and resulting in inconsistent sizes of the finished products. Furthermore, for the slitting requirements of capacitor films of different widths, traditional devices require independent cutting equipment, and the cutting position is difficult to adjust. In practical use, adjusting the cutting position relies too heavily on manual measurement and calibration, making operation cumbersome. Therefore, those skilled in the art have provided an automatic winding device for capacitor film production to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to provide an automatic winding device for capacitor film production to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatic winding device for capacitor film production includes a mounting frame, on which a pair of opposing quick-release components are rotatably connected, and a winding roller is disposed between the two quick-release components. The mounting frame is provided with a detection component for detecting the winding degree, and a power component for driving the quick-release components to rotate is also disposed inside the mounting frame.
[0005] Furthermore, the detection component includes a connecting piece, a first electro-hydraulic telescopic rod, and a fixed shaft. The fixed shaft is fixedly connected to the mounting bracket, and the connecting piece is rotatably connected to the surface of the fixed shaft. The first electro-hydraulic telescopic rod is rotatably connected to the inner layer of the mounting bracket via contacts, and the output end of the first electro-hydraulic telescopic rod is rotatably connected to the connecting piece via contacts.
[0006] Furthermore, the detection assembly also includes a detection roller and a connecting shaft, with the connecting shaft fixedly connected to the connecting piece and the detection roller disposed on the surface of the connecting shaft.
[0007] Furthermore, the power assembly includes a servo motor, a first pulley, a transmission belt, and a second pulley. The servo motor is fixedly connected to the inside of the mounting bracket. The first pulley is provided at the output end of the servo motor. The second pulley is provided at the end of the quick-release piece away from the take-up roller. The transmission belt is provided on the first pulley and the second pulley.
[0008] Furthermore, the mounting frame is also provided with a cutting assembly, which includes a bracket, a longitudinal sliding block, a longitudinal slide rail and a support plate. The support plate is fixedly connected to the inner side of the mounting frame, the longitudinal slide rail is fixedly connected to the upper surface of the support plate, the longitudinal sliding block is slidably connected to the longitudinal slide rail, and the bracket is fixedly connected to the longitudinal sliding block.
[0009] Furthermore, the cutting assembly also includes a second electro-hydraulic telescopic rod and a transmission plate. The second electro-hydraulic telescopic rod is fixedly connected to the mounting bracket, and the transmission plate is fixedly connected to the upper surface of the bracket. The output end of the second electro-hydraulic telescopic rod is fixedly connected to the transmission plate.
[0010] Furthermore, the cutting assembly also includes a transverse mounting rail, a mounting sliding block, a locking rod, a fixing plate, and a cutting blade.

[0011] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. The detection component works in concert with the fixed shaft, connecting piece, first electro-hydraulic telescopic rod and detection roller. The detection roller is always in contact with the film surface during the winding process. As the film winding thickness increases, the connecting piece rotates around the fixed shaft and triggers the extension and retraction feedback of the first electro-hydraulic telescopic rod. The winding thickness change can be monitored in real time, and the winding completion status can be accurately judged. This avoids over-winding that may damage the film or under-winding that may affect subsequent processing. 2. The sliding connection structure between the horizontal mounting rail and the mounting slider can adjust the position of the cutting blade according to the width of the capacitor film. Combined with the fixing effect of the locking rod, it ensures accurate cutting position, adapts to the production needs of films with different width specifications, and has strong versatility. 3. The cutting assembly, through the cooperation of the longitudinal slide rail and the longitudinal sliding block, can drive the support to move rapidly along the longitudinal direction under the drive of the second electro-hydraulic telescopic rod, so as to realize the film slitting work during the winding process. The cutting efficiency is high and the cut surface is flat, avoiding film tearing. 4. From winding drive and thickness detection to automatic adjustment of cutting position, the entire process is automated, eliminating the need for frequent manual intervention, reducing the intensity of manual operation, and minimizing the impact of human error on product quality.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figs. 1-4 This utility model provides an embodiment of an automatic winding device for capacitor film production, including a mounting frame 7. A pair of opposing quick-release components 2 are rotatably connected to the mounting frame 7, and a winding roller 1 is disposed between the two quick-release components 2. The mounting frame 7 is provided with a detection component for detecting the winding degree, and a power component for driving the quick-release components 2 to rotate is also disposed inside the mounting frame 7. After fixing the mounting frame 7 to the production station, the winding roller 1 is installed between the opposing quick-release components 2 on the mounting frame 7, and the winding roller 1 is fixed by the locking structure of the quick-release components 2. Then, the connection status of the power component, detection component and cutting component is checked to ensure that the servo motor 20 is normally engaged with the first pulley 21 and the second pulley 23 through the transmission belt 22, the detection roller 3 is kept parallel to the surface of the winding roller 1, and the cutting blade 19 is in the initial standby position.
[0015] In this embodiment, the detection component includes a connecting piece 5, a first electro-hydraulic telescopic rod 6, and a fixed shaft 8. The fixed shaft 8 is fixedly connected to the mounting frame 7, and the connecting piece 5 is rotatably connected to the surface of the fixed shaft 8. The first electro-hydraulic telescopic rod 6 is rotatably connected to the inner layer of the mounting frame 7 via contacts. The output end of the first electro-hydraulic telescopic rod 6 is rotatably connected to the connecting piece 5 via contacts. The detection component also includes a detection roller 3 and a connecting shaft 4. The connecting shaft 4 is fixedly connected to the connecting piece 5, and the detection roller 3 is provided on the surface of the connecting shaft 4. During the winding process, the detection roller 3 of the detection component is always in contact with the film surface. As the film winding thickness gradually increases, the detection roller 3 is subjected to a leftward squeezing force, which drives the connecting piece 5 to rotate around the fixed shaft 8. The rotation of the connecting piece 5 triggers the extension and retraction of the first electro-hydraulic telescopic rod 6. The first electro-hydraulic telescopic rod 6 feeds back the extension and retraction amount through a built-in sensor, which is converted into film winding thickness data in real time. When the thickness reaches a preset value, the system determines that winding is complete and automatically issues a stop signal to avoid over-winding or under-winding.
[0016] In this embodiment, the power assembly includes a servo motor 20, a first pulley 21, a transmission belt 22, and a second pulley 23. The servo motor 20 is fixedly connected to the inner side of the mounting bracket 7. The first pulley 21 is provided at the output end of the servo motor 20. The second pulley 23 is provided at the end of the quick-release piece 2 away from the take-up roller 1. The transmission belt 22 is provided on the first pulley 21 and the second pulley 23. When the servo motor 20 in the power assembly is started, the servo motor 20 drives the first pulley 21 to rotate. The power is transmitted to the second pulley 23 through the transmission belt 22, thereby driving the quick-release piece 2 and the take-up roller 1 to rotate synchronously. The capacitor film is then wound around the surface of the take-up roller 1. The servo motor 20 can adjust its speed according to production needs to ensure smooth winding.
[0017] In this embodiment, the mounting frame 7 is further provided with a cutting assembly, which includes a bracket 11, a longitudinal sliding block 12, a longitudinal slide rail 13, and a support plate 14. The support plate 14 is fixedly connected to the inner side of the mounting frame 7, and the longitudinal slide rail 13 is fixedly connected to the upper surface of the support plate 14. The longitudinal sliding block 12 is slidably connected to the longitudinal slide rail 13, and the bracket 11 is fixedly connected to the longitudinal sliding block 12. The cutting assembly also includes a second electro-hydraulic telescopic rod 9 and a transmission plate 10. The second electro-hydraulic telescopic rod 9 is fixedly connected to the mounting frame 7, and the transmission plate 10 is fixedly connected to the upper surface of the bracket 11. The output end of the second electro-hydraulic telescopic rod 9 is fixedly connected to the transmission plate 10. The cutting assembly also includes a transverse mounting rail 15, a mounting sliding block 16, a locking rod 17, a fixing plate 18, and a cutting blade 19. The transverse mounting rail 15 is fixedly connected to the bracket 11, and the mounting sliding block 16 is slidably connected to the transverse mounting rail 15. A fixing plate 18 is fixedly connected to block 16. A cutting blade 19 is provided on the fixing plate 18. A locking rod 17 is also threaded through and connected to the fixing plate 18. The lower end of the locking rod 17 abuts against the transverse mounting rail 15. According to the width specification of the capacitor film, the locking rod 17 on the fixing plate 18 in the cutting assembly is loosened, and the mounting sliding block 16 is pushed to slide along the transverse mounting rail 15 until the cutting blade 19 is aligned with the preset cutting position. Then the locking rod 17 is tightened to complete the cutting position fixation, which is suitable for the slitting requirements of films of different widths. If slitting is required during the film winding process, the second electro-hydraulic telescopic rod 9 is activated. The second electro-hydraulic telescopic rod 9 pushes the transmission plate 10 to drive the bracket 11 to move quickly along the longitudinal slide rail 13. The cutting blade 19 on the bracket 11 moves synchronously to achieve rapid cutting of the film. During the cutting process, the longitudinal slide rail 13 ensures that the bracket 11 moves smoothly, ensuring a flat cutting surface and avoiding film tearing.
[0018] The detection component, through the coordinated action of the fixed shaft 8, connecting piece 5, first electro-hydraulic telescopic rod 6, and detection roller 3, ensures that the detection roller 3 remains in contact with the film surface during the winding process. As the film winding thickness increases, the connecting piece 5 rotates around the fixed shaft 8, triggering the extension and retraction feedback of the first electro-hydraulic telescopic rod 6. This allows for real-time monitoring of changes in winding thickness, accurate judgment of winding completion status, and prevention of over-winding leading to film damage or under-winding affecting subsequent processing. The sliding connection structure between the transverse mounting rail 15 and the mounting sliding block 16 allows for adjustment of the position of the cutting blade 19 according to the width of the capacitor film, in conjunction with the locking rod. The fixing function of 17 ensures precise cutting position, adapts to the production needs of films with different width specifications, and has strong versatility; the cutting component, through the cooperation of longitudinal slide rail 13 and longitudinal sliding block 12, can drive the support 11 to move quickly along the longitudinal direction under the drive of the second electro-hydraulic telescopic rod 9, realize the film slitting work during winding, with high cutting efficiency and flat cut surface, avoiding film tearing; from winding drive, thickness detection and automatic adjustment of cutting position, the whole process is automated, without frequent manual intervention, reducing the intensity of manual operation and reducing the impact of human operation error on product quality.
