Description

Technical Field

[0001] This utility model relates to the field of capacitor film production technology, specifically a capacitor film cooling and forming device. Background Technology

[0002] During the manufacturing process of capacitor films, surface smoothness and temperature control have a crucial impact on their final performance. Capacitor films are typically manufactured in a multi-step process, including film extrusion, cooling, and shaping. Especially during the film cooling stage, ensuring the smoothness of the film surface, preventing deformation, and maintaining uniform cooling are key factors in improving the quality of capacitor films.

[0003] While some existing cooling systems can provide cooling, they still have shortcomings in the flow of coolant and the shaping of the capacitor diaphragm. Traditional cooling systems often lack effective mechanisms to ensure uniform coolant flow, leading to uneven cooling in some areas and potentially causing wrinkles and unevenness on the capacitor diaphragm surface. Furthermore, existing cooling systems often fail to effectively shape the capacitor diaphragm, making the diaphragm surface prone to deformation, affecting its quality and stability.

[0004] To address these issues, a novel capacitor film cooling and shaping device is proposed. This device aims to remove wrinkles and unevenness from the film surface by utilizing the cooperation between the shaping roller and the inner wall of the cooling tank, as well as the uniform pressing of the shaping roller on the capacitor film surface during planetary rotation. Simultaneously, it prevents film deformation during cooling. Furthermore, this invention ensures uniform coolant flow by agitating the coolant during the rotation of the shaping roller, preventing uneven cooling and ensuring the capacitor film can complete cooling and shaping in a stable environment, thus improving the long-term stability and quality of the film. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] This utility model relates to a capacitor film cooling and forming device, particularly a device for cooling and shaping during the capacitor film manufacturing process. The purpose of this utility model is to remove wrinkles and uneven parts from the capacitor film surface by utilizing the cooperation between the shaping roller and the inner wall of the cooling tank, and by the uniform pressing of the shaping roller on the capacitor film surface during planetary rotation, thereby improving the quality and long-term stability of the capacitor film. Simultaneously, the rotation of the shaping roller agitates the coolant, ensuring uniform coolant flow and preventing uneven cooling, thus ensuring a stable and uniform cooling process for the capacitor film.

[0007] Specifically, this utility model achieves its objective through the following technical solution:

[0008] This utility model includes a shaping guide, a cooling tank, and a shaping roller rotatably installed inside the cooling tank.

[0009] The surface of the shaping guide is provided with a set of transmission rollers and a set of membrane pressure dewatering rollers, and the surface of the shaping guide is provided with a transmission component for driving the set of transmission rollers and the set of membrane pressure dewatering rollers to rotate; the set of membrane pressure dewatering rollers includes several pressure rollers that abut against each other and are driven by each other, and the surface of the pressure rollers is provided with elastic sleeves, which are press-fitted against each other.

[0010] The cooling tank is fixed to the inner side of the guide frame, and a slip ring interface is rotatably installed at one end of the cooling tank for connecting to the coolant circulation pipeline. A drive disc is rotatably installed at the other end of the cooling tank, and the surface of the drive disc is provided with a moving gear disc that drives the surface of the transmission assembly. A cooling circulation pump unit is connected to the end of the slip ring interface. The cooling circulation pump unit includes circulation pipelines, a pump body, and cooling components, for continuously supplying circulating coolant to the inside of the slip ring interface.

[0011] A fixed gear ring is fixedly installed on one side of the inner cavity of the cooling tank. A split shaft seat is provided on the surface of the cooling tank, and planetary gears are rotatably mounted on the surface of the split shaft seat. One end of the planetary gears is fixedly connected to the end of the shaping roller, and the surface of the shaping roller is provided with a guide bar.

[0012] This invention utilizes the cooperation between the shaping roller and the inner wall of the cooling tank. During planetary rotation, the shaping roller uniformly presses the surface of the capacitor film, effectively removing wrinkles and uneven areas. Furthermore, the shaping roller performs physical shaping simultaneously with film cooling, helping to prevent deformation when the film temperature reaches a stable range, thereby improving the long-term stability of the capacitor film. Several shaping rollers are arranged in a planetary pattern, and each roller meshes with the inner side of a fixed gear ring via planetary teeth. These planetary teeth are rotatably mounted on the surface of a moving gear disc to follow the disc's rotation in a revolution.

[0013] During planetary rotation, the shaping roller agitates the coolant by interacting with the inner wall of the cooling tank. This avoids stagnant and dead zones in the coolant, ensuring more uniform flow. Uniform coolant flow ensures stable cooling of the capacitor membrane, preventing uneven cooling and localized overcooling or overheating, thus ensuring stable membrane shape and performance. The shaping roller has two spiral guide strips on its surface, symmetrically arranged about the midpoint of the roller's surface. The two guide strips are connected at their ends.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] 1. In this invention, the shaping roller, through its cooperation with the inner wall of the cooling tank, uniformly presses the surface of the capacitor film during planetary rotation. This effectively removes wrinkles and uneven areas from the film surface, allowing for physical shaping while the film cools. This helps prevent deformation once the film temperature reaches a stable range. This enables the capacitor film to complete cooling and shaping in a relatively stable state, thereby improving its long-term stability.

[0016] 2. In this utility model, by disturbing the coolant during the planetary rotation of the shaping roller, the stagnation zone and dead zone of the coolant can be avoided, making the coolant flow more uniform, thereby ensuring that the cooling process of the capacitor film is uniform and stable, avoiding the phenomenon of local overcooling or overheating, and ensuring the shape and performance of the film.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following is in conjunction with the appendix Figures 1-4 This invention describes a capacitor film cooling and forming apparatus provided by some embodiments of the present invention.

[0026] This embodiment provides a capacitor film cooling and forming device, which adopts the structural scheme shown in the figure. The overall structure includes a shaping guide 100, a cooling tank 200, and a shaping roller 300 installed on the inner wall of the cooling tank.

[0027] The shaping guide 100 is a frame structure used to support and fix the cooling tank 200 and the shaping roller 300. Its surface is provided with multiple drive roller groups 120 and membrane pressure dewatering roller groups 130. The drive roller groups 120 cooperate with the membrane pressure dewatering roller groups 130 through a drive assembly 110 to drive the transfer and pressing of the capacitor membrane during the forming process. The membrane pressure dewatering roller group 130 includes several mutually abutting and driving pressure rollers, and the surface of the pressure rollers is provided with elastic sleeves that press against each other.

[0028] The cooling tank 200 adopts a semi-circular cylindrical tank structure, which is simple and robust, and can effectively hold coolant. The inner wall of the cooling tank mates with the shaping roller 300 to ensure that the capacitor film maintains good flatness during the cooling process. One end of the cooling tank 200 is equipped with a slip ring interface 210, through which a coolant circulation pipeline is connected to ensure continuous flow of coolant; the end of the slip ring interface 210 is connected to a cooling circulation pump set, which includes circulation pipeline, pump body and cooling components, for continuously supplying circulating coolant to the inside of the slip ring interface 210.

[0029] The shaping roller 300 is installed on the inner wall of the cooling tank 200 and operates by planetary rotation. The surface of the shaping roller 300 is provided with guide strips 310, which can apply uniform pressure to the surface of the capacitor film during planetary rotation. By cooperating with the inner wall of the cooling tank 200, the shaping roller 300 removes wrinkles and uneven parts from the surface of the capacitor film and performs physical shaping during film cooling, preventing deformation of the film surface during cooling. Several shaping rollers 300 are distributed in a planetary manner, and each shaping roller 300 meshes with the inner side of the fixed gear ring 240 via planetary teeth 222. The planetary teeth 222 are rotatably mounted on the surface of the moving gear disk 230 to follow the rotation of the moving gear disk 230 in a revolution.

[0030] During planetary rotation, the shaping roller 300 agitates the coolant within the cooling tank 200 through rotation and friction with the inner wall of the cooling tank 200. This agitation promotes uniform flow of the coolant, effectively preventing the formation of stagnant or dead zones. This ensures that the coolant can contact the capacitor membrane evenly, improving cooling efficiency and preventing overcooling or overheating of the membrane surface.

[0031] In another embodiment, the cooling tank 200 of this invention can be designed in different structural forms, such as a circular tank or a rectangular tank. The shape and size of the cooling tank can be flexibly adjusted according to different applications and the requirements of the capacitor film. In addition, the guide strips 310 of the shaping roller 300 can be arranged differently according to the type and thickness of the capacitor film to optimize the shaping effect. There are two guide strips 310 on the surface of the roller 300, and the two guide strips 310 are symmetrically arranged about the midpoint of the surface of the shaping roller 300. The guide strips 310 are arranged in a spiral, and the ends of the two guide strips 310 are connected.

[0032] In this embodiment, the flow rate and cooling efficiency of the coolant can be enhanced by adding coolant pumps, such as a circulation pump set, to the coolant circulation pipeline. These pumps can automatically adjust according to the temperature and flow rate of the coolant, ensuring that the coolant flow is always kept in an optimal state, thereby improving the stability and uniformity of the entire cooling process.

[0033] Summary of detailed implementation methods:

[0034] Through the above embodiments, this invention can effectively improve the cooling and shaping effect of the capacitor film. By cooperating with the inner wall of the cooling tank 200 and the shaping roller 300, the surface of the capacitor film is uniformly pressed and shaped during the cooling process, avoiding problems such as wrinkles, deformation, and uneven cooling. Simultaneously, the disturbance of the coolant ensures uniform flow of the coolant, thereby optimizing the overall cooling effect of the capacitor film.

[0035] The capacitor film cooling and forming device provided by this utility model can not only improve the surface quality of the capacitor film, but also ensure the stability of the film cooling process, thereby improving the long-term stability and quality of the capacitor film, and is widely applicable to the production process of capacitor film.
