Capacitor films usually use plastic films such as polyethylene terephthalate, polypropylene, polystyrene, or polycarbonate as dielectrics, and a metal film is vacuum-evaporated as an electrode; in the production process of capacitor films, winding is a key link. However, due to the different characteristics of capacitor films such as ultra-thin, narrow, high sheet resistance, and grid film, as well as the characteristic of smooth surface, traditional winding methods face many problems. During the winding process, it is necessary to ensure that the winding speed matches the conveying speed of the film to avoid problems such as wrinkles or uneven stretching. During the high-speed winding process, the film is prone to generating static electricity when rubbing against the air, adsorbing suspended particles in the air, affecting the cleanliness of the film and the performance of the capacitor. The air content remaining between the film layers has an important impact on the performance of the capacitor. How to effectively control the air content during the winding process is a problem that needs to be solved. In summary, capacitor film winding faces problems such as film tension control, film uniformity and stability control, matching of winding speed and accuracy, static electricity and air content problems, as well as equipment complexity and maintenance costs.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0018] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a capacitor film winding device, which specifically includes a conveying frame 1, a winding platform 2, a film flattening assembly, an electrostatic component, and a winding component. The conveying frame 1 is arranged on the winding platform 2, and a film conveying belt 3 is arranged on the conveying frame 1. The conveying frame 1 and the film conveying belt 3 provide a stable film conveying path, ensuring that the film can move continuously and smoothly to the subsequent processing area. The conveying frame 1 and the winding platform 2 serve as the basis of the entire winding device, responsible for conveying and winding the capacitor film from the source. One end of the film conveying belt 3 is provided with a film flattening assembly. The film flattening assembly includes a flattening roller 4, a tension adjusting roller 5, a guide plate 6, and a film guiding plate 7. The flattening roller 4 is rotatably arranged on the guide plate 6 through a connecting block 8. The guide plate 6 is arranged on both sides of the conveying frame 1. The tension adjusting roller 5 is rotatably arranged between the guide plates 6 and is arranged parallel to the flattening roller 4. The film guiding plate 7 is fixed on the guide plate 6 through an adjusting screw. In practice, the flattening roller 4 applies a certain pressure and tension to the film by rolling contact, thereby eliminating wrinkles, corrugations, or distortions that may occur during the conveying process of the film. The flattening roller is rotatably arranged on the guide plate 6 through the connecting block 8, enabling the flattening roller to flexibly adjust its position and angle to adapt to films of different specifications and materials. The tension adjusting roller 5 adjusts the relative position or pressure between the tension adjusting roller and the flattening roller 4, which can control the tightness of the film, preventing the film from breaking due to excessive tension or becoming loose and wrinkled due to insufficient tension during the conveying process. The guide plate 6 plays a role of guiding and supporting, providing a stable installation basis for the flattening roller 4 and the tension adjusting roller 5, and also ensuring that the film maintains the correct path and direction during the conveying process. The film guiding plate 7 adjusts and controls the conveying path and position of the film. The film guiding plate fixed on the guide plate 6 through an adjusting screw can adjust its position and angle according to actual needs to ensure that the film can accurately enter the subsequent processing or packaging equipment. The electrostatic component includes a mounting base 9, an electrostatic eliminator housing 10, a high-voltage generator 11, a discharge plate 12, and a ventilation component. The mounting base 9 mounts the electrostatic eliminator housing 10 on the conveying frame 1. The high-voltage generator 11 is arranged inside the electrostatic eliminator housing 10. The high-voltage generator 11 is connected to the discharge plate 12 below. The ventilation component is arranged on one side of the mounting base 9. The winding component includes a winding roller 13, a winding disc 14, and a winding frame 15. The winding roller 13 is rotatably arranged on the winding platform 2 through the winding frame 15. The winding disc 14 is arranged on the winding roller 13. The mounting base 9 serves as the support structure of the electrostatic eliminator housing 10. The electrostatic eliminator housing 10 protects the internal high-voltage generator 11 from external interference and damage to the internal equipment. The high-voltage generator 11 is responsible for generating high voltage, and this high voltage is transmitted to the discharge plate 12 through wires, causing the discharge plate 12 to generate sufficient electric field intensity to neutralize the static electricity accumulated on the film or other materials during the conveying process. When the high voltage is transmitted to the discharge plate 12, a strong electric field is generated, which can neutralize the static charges on the surface of the film or other materials, thereby achieving the purpose of eliminating static electricity.The winding roller 13 on the winding component winds up the film or other materials after static elimination treatment. The winding roller 13 is rotatably arranged on the winding platform 2 through the winding frame 15 and can automatically rotate along with the conveying of the materials to realize the continuous winding of the materials. The winding disc 14 is usually arranged on the winding roller 13 and is used to fix and support the materials wound on the winding roller. It ensures the stability and tightness of the materials during the winding process.

[0019] As Figure 3 shown, on the basis of the above method, further, an insulating plate 16 and an overload protector 17 are equipped on the side of the static electricity component. The insulating plate 16 is arranged to fit one side of the static eliminator housing 10, and the overload protector 17 is arranged on the mounting base 9. In specific implementation, the insulating plate 16 and the overload protector 17 enhance the safety and reliability of the static electricity component, prevent accidents caused by electrical failures. The insulating plate 16 prevents current leakage and protects the safety of the operator; the overload protector 17 automatically cuts off the power supply when the electrical load is too large to prevent equipment damage.

[0020] As Figure 3 shown, on the basis of the above method, further, the ventilation assembly includes a fan 18 and an air flow channel 19. The fan 18 is arranged on the mounting base 9, and the air flow channel 19 is arranged on one side of the static eliminator housing 10; in specific implementation, the fan 18 generates air flow, and then the air flow is guided to the inside or the surrounding area of the static eliminator housing 10 through the air flow channel 19. The air flow channel 19 is responsible for guiding the air flow generated by the fan 18 to one side of the static eliminator housing 10. The air flow channel 19 can optimize the distribution of the air flow, make it more uniform and effectively act on the static eliminator or the film surface, and further improve the efficiency and stability of static elimination.

[0021] As Figure 1 shown, on the basis of the above method, further, a control panel 20 is arranged on the winding platform 2. The high-voltage generator 11 is electrically connected to the control panel 20, and an emergency stop button 21 and a display and monitoring screen 22 are arranged on the control panel 20. In specific implementation, the control panel 20, the emergency stop button 21 and the display and monitoring screen 22 improve the automation degree and operation convenience of the equipment, facilitate real-time monitoring and emergency control. The control panel 20 is used to set and adjust the equipment parameters; the emergency stop button 21 quickly cuts off the power supply in case of emergency; the display and monitoring screen 22 displays the equipment status and parameter information in real time.

[0022] As Figure 4As shown, further on the basis of the above method, a guide roller 23, a tension adjusting roller 24, a pressing roller 25 and an auxiliary support roller 26 are arranged between the mounting base 9 and the winding frame 15. The tension adjusting roller 24 and the pressing roller 25 are arranged up and down on the winding frame 15. The guide roller 23 is arranged between the tension adjusting roller 24 and the electrostatic component, and the auxiliary support roller 16 is arranged between the pressing roller 25 and the winding roller 13. In specific implementation, the guide roller 23 mainly plays a role in guiding and positioning the film, ensuring that the film can maintain the correct path and direction during transportation, and avoiding deviation or wrinkles. Through the guidance of the guide roller 23, the film can smoothly enter the tension adjusting roller 24 and the subsequent winding process. The tension adjusting roller 24 and the pressing roller 25 are used in cooperation to precisely control the film tension by adjusting the relative position or pressure between the two. The tension adjusting roller 24 can ensure that the film maintains a constant tension during transportation and winding, thereby preventing the film from breaking due to excessive tension or becoming loose and wrinkled due to insufficient tension. The pressing roller 25 is mainly used to apply a certain pressure to the film to make it fit more closely under the tension adjusting roller 24, ensuring that the film does not slip or fall off during the winding process. The auxiliary support roller 26 is arranged between the pressing roller 25 and the winding roller 13 and mainly plays a role in supporting and assisting the winding.

[0023] As Figure 1 shown, further on the basis of the above method, a winding motor 27 is arranged on one side of the winding roller 12. In specific implementation, the winding motor 27 provides a stable power source for the winding roller 15, ensuring the continuity and efficiency of the winding process, driving the winding roller 15 to rotate, and completing the automatic winding work of the film.

[0024] In the specific working process of this new type of capacitor film winding device, the capacitor film is first placed on the film conveying belt 3 on the conveying rack 1; the conveyor belt 3 starts, driving the film to move forward smoothly and continuously along the set path. The film enters the film flattening assembly area and first passes through the flattening roller 4. The flattening roller 4 contacts the film through rolling, applying a certain pressure and tension to eliminate wrinkles, corrugations or distortions that may occur during the conveying process of the film. Then, the film passes through the tension adjusting roller 5. By adjusting the relative position or pressure between the tension adjusting roller 5 and the flattening roller 4, the tightness of the film is controlled to prevent the film from breaking due to excessive tension or from becoming loose and wrinkled due to insufficient tension. The guide plate 6 and the film guiding plate 7 ensure that the film maintains the correct path and direction during the conveying process. The film continues to move to the electrostatic component area. The high-voltage generator 11 generates high-voltage electricity, and this high-voltage electricity is transmitted to the discharge plate 12 through wires, causing the discharge plate 12 to generate a sufficient electric field intensity. The electric field neutralizes the static charges on the surface of the film to achieve the purpose of eliminating static electricity. At the same time, the airflow generated by the fan 18 is guided through the airflow channel 19 to the inside or the surrounding area of the electrostatic eliminator housing 10 to further assist the static electricity elimination process. After the film passes through the static electricity elimination, it enters the winding component area. In this area, the film passes through the guiding roller 23, the tension adjusting roller 24, the pressing roller 25 and the auxiliary supporting roller 26 to further adjust the tension and flatness of the film. The tension adjusting roller 24 and the pressing roller 25 work together to ensure that the film maintains an appropriate tightness and stability during the winding process. The film finally reaches the winding roller 13, and the winding roller 13 is driven by the winding motor 27 to rotate, winding the film around the winding disc 14. As the film is continuously conveyed, the winding roller 13 continues to rotate to achieve continuous winding of the film. During the entire winding process, the operator can monitor the device status and parameter information in real time through the control panel 20. In case of an emergency, the emergency stop button 21 can be quickly pressed to cut off the power supply to ensure the safety of the device and personnel. When the predetermined winding amount is reached or the winding disc needs to be replaced, the conveying belt 3 and the winding motor 27 are stopped, the fully wound film winding disc is removed, a new winding disc is replaced, and the device is restarted to continue the winding work.
