Description

Technical Field

[0001] This utility model relates to the technical field of capacitor film production equipment, specifically a high-efficiency cooling device for capacitor film production. Background Technology

[0002] Capacitor film is a dielectric material used to manufacture thin-film capacitors. It is usually made of polymer materials such as polyester, polypropylene, polystyrene or polycarbonate. These materials have good electrical insulation and mechanical properties, can store charge and isolate current in electronic components, and are used to manufacture components such as capacitors, electronic filters, and sensors.

[0003] A search of patent number CN202322244389.1 reveals a capacitor film cooling and forming device, comprising: a forming roller frame, a pressure roller, a cooling roller assembly, a dynamic joint, and a compression refrigeration device for temperature control. The device utilizes the rotation of the guide roller, pressure roller, and cooling roller assembly to transport and drive the polypropylene capacitor film in an assembly line operation. Rapid heat conduction and cooling of the polypropylene capacitor film are achieved through contact with the surface of the cooling roller assembly. The cooling roller assembly is kept at a continuously low temperature by the internal coolant and coil structure, resulting in stable cooling and high forming efficiency.

[0004] However, the aforementioned patent can only cool one side when cooling through the cooling roller assembly, and the other side can only be cooled by conduction. Therefore, it cannot achieve simultaneous cooling of both sides. In addition, since the heat-conducting outer cylinder does not have a closed space during the cooling process, the cold air will diffuse in the space, thus making the cooling worse. Furthermore, the rollers cannot be adjusted, so the distance between the rollers is constant, making it impossible to cool capacitor films of different thicknesses. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency cooling device for capacitor film production. It solves the problems of only being able to cool one side, thus making it impossible to cool both sides simultaneously. In addition, during the cooling process of the cooling roller assembly, since the heat-conducting outer cylinder has no enclosed space, the cold air will diffuse into the space, thus worsening the cooling. Furthermore, the distance between the rollers cannot be adjusted, so it is impossible to cool capacitor films of different thicknesses.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency cooling device for capacitor film production, comprising a frame, wherein a cooling component and an adjustment component are respectively provided on the top and sides of the frame.

[0007] The cooling assembly includes an upper cover, a lower cover, and a refrigeration device. The top of the upper cover is fixedly connected to a first cylinder via a connecting rod, and the bottom of the lower cover is fixedly connected to a second cylinder. A roller is provided between the upper and lower covers through a rotating notch, and the surface of the roller is symmetrically provided with ventilation holes. One end of the roller is rotatably sleeved with a connector, and one end of the connector is fixedly connected to an input pipe and an output pipe, while the other end is fixedly connected to a first coil and a second coil. The input pipe is connected to the first coil, and the output pipe is connected to the second coil. The refrigeration device is connected to the input pipe and the output pipe, and the first coil and the second coil are located in the inner cavity of the roller.

[0008] Preferably, the adjustment assembly includes a U-shaped frame, and a sleeve plate is fixedly connected to the surface of the U-shaped frame. A rotating rod is rotatably sleeved in the middle of the sleeve plate, and a rubber disc is fixedly installed on the surface of the sleeve plate. A third cylinder is rotatably connected to the middle of the U-shaped frame.

[0009] Preferably, one end of the third cylinder and the surface of the sleeve plate are respectively mounted on the side and bottom of the frame via movable parts.

[0010] Preferably, the first cylinder and the second cylinder are fixedly installed at the top and bottom of the frame, respectively, and the refrigeration equipment is fixedly installed on the side of the frame. The upper cover and the lower cover cover each other, and there is a gap between the front and back.

[0011] Preferably, the roller is rotatably sleeved on the frame, and a drive motor is fixedly installed in the inner cavity of the frame. Both the output end of the drive motor and one end of the roller are fixedly connected to pulleys, and a belt is movably sleeved on the surface of the pulleys.

[0012] Preferably, a bracket is fixedly installed on the surface of the frame, and a winding roller is rotatably arranged between the brackets, and a placement platform is fixedly installed on one side of the frame.

[0013] This invention provides a high-efficiency cooling device for capacitor film production. Compared with the prior art, it has the following advantages:

[0014] This high-efficiency cooling device for capacitor film production uses two rollers to wind both sides of the capacitor film, allowing for cooling of both sides. It also collects the cold air through vents in the upper and lower covers, reducing its diffusion into the air and continuously cooling the capacitor film, thereby improving the cooling effect.

[0015] 2. The high-efficiency cooling device for capacitor film production uses a third cylinder to drive a U-shaped frame to rotate on the frame via a movable part, thereby increasing the height of the rotating rod and squeezing the capacitor film to achieve a tensioning effect. This tensioning allows the capacitor film to be tightly adhered to the two rollers, thus achieving a cooling effect for capacitor films of different thicknesses. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2This utility model provides a technical solution: a high-efficiency cooling device for capacitor film production, including a frame 1, a cooling component 5 and an adjustment component 6 respectively provided on the top and side of the frame 1, a bracket 2 fixedly installed on the surface of the frame 1, and a winding roller 3 rotatably arranged between the brackets 2, and a placement platform 4 fixedly installed on one side of the frame 1, wherein the winding roller 3 is used to wind up the capacitor film, and the placement platform 4 can be used to place the capacitor film after winding is completed.

[0025] Please see Figure 3 The adjusting component 6 includes a U-shaped frame 61, and a sleeve plate 64 is fixedly connected to the surface of the U-shaped frame 61. A rotating rod 63 is rotatably sleeved in the middle of the sleeve plate 64, and a rubber disc 65 is fixedly installed on the surface of the sleeve plate 64. A third cylinder 62 is rotatably connected in the middle of the U-shaped frame 61. One end of the third cylinder 62 and the surface of the sleeve plate 64 are respectively installed on the side and bottom of the frame 1 through movable parts 66. The movable parts 66 enable the third cylinder 62 to achieve automatic rotation when starting and pushing the U-shaped frame 61, so that the capacitor film is pressed against the rotating rod 63, and the capacitor film can follow the rotation of the rotating rod 63 for transportation. In addition, the rubber disc 65 on the sleeve plate 64 can press against both sides of the capacitor film to limit the capacitor film and prevent the problem of displacement.

[0026] Please see Figure 4-6 The cooling assembly 5 includes an upper cover 51, a lower cover 52, and a cooling device 53. The top of the upper cover 51 is fixedly connected to a first cylinder 55 via a connecting rod 54, and the bottom of the lower cover 52 is fixedly connected to a second cylinder 57. The first cylinder 55 and the second cylinder 57 are respectively fixedly installed on the top and bottom of the frame 1, and the cooling device 53 is fixedly installed on the side of the frame 1. The upper cover 51 and the lower cover 52 cover each other, and there is a gap between the front and back. The gap is used for the entry of the capacitor film and does not affect the delivery of the capacitor film. A roller 58 is provided between the upper cover 51 and the lower cover 52 through a rotating notch 56. The rotating notch 56 can wrap the roller 58 when the upper cover 51 and the lower cover 52 are closed, without affecting the rotation of the roller 58.

[0027] The roller cylinder 58 is rotatably sleeved on the frame 1, and the surface of the roller cylinder 58 is symmetrically provided with vent holes 59. One end of the roller cylinder 58 is rotatably sleeved with a connector 510, and one end of the connector 510 is fixedly connected to the input pipe 511 and the output pipe 512, and the other end is fixedly connected to the first coil 513 and the second coil 514. The input pipe 511 is connected to the first coil 513, and the output pipe 512 is connected to the second coil 514. The refrigeration device 53 is connected to the input pipe 511 and the output pipe 512. The first coil 513 and the second coil 514 are located in the inner cavity of the roller cylinder 58. The two roller cylinders 58 can wind both sides of the capacitor film, and both sides of the capacitor film can be refrigerated. The vent holes 59 can collect the generated cold air in the closed space of the upper cover 51 and the lower cover 52, which can reduce the diffusion of cold air into the air and make the refrigeration effect better.

[0028] A drive motor 9 is fixedly installed in the inner cavity of the frame 1, and a pulley 7 is fixedly connected to the output end of the drive motor 9 and one end of the roller cylinder 58. A belt 8 is movably sleeved on the surface of the pulley 7. When the drive motor 9 is started, the roller cylinder 58 is driven to rotate on the frame 1 through the transmission of the pulley 7 and the belt 8.

[0029] During operation or use, firstly, the first cylinder 55 and the second cylinder 57 are activated to move the upper cover 51 and the lower cover 52 accordingly, exposing the roller cylinder 58. Then, the capacitor film is first pressed against the rotating rod 63, and then the rubber disc 65 on the sleeve 64 will adhere to both sides of the capacitor film, achieving a limiting function to prevent displacement. The capacitor film is then wound around the two roller cylinders 58, first from the top and then from the bottom, so that the two roller cylinders 58 can contact both sides of the capacitor film. Finally, the capacitor film is wound onto the take-up roller 3 set on the bracket 2, and then the first cylinder 55 and the second cylinder 57 are activated. The second cylinder 57 then closes the upper cover 51 and the lower cover 52, covering the roller cylinder 58. There are gaps between the upper cover 51 and the lower cover 52, which are used for conveying the capacitor film. Then, the drive motor 9 is started, which drives the roller cylinder 58 to rotate through the transmission of the pulley 7 and the belt 8, thereby conveying the capacitor film. Since the connector 510 is rotated and sleeved on one end of the roller cylinder 58, the connector 510 does not move during the rotation of the roller cylinder 58. Therefore, the first coil 513 and the second coil 514 also do not move. Only the roller cylinder 58 rotates.

[0030] During cooling, the refrigeration equipment 53 is started first. The liquid refrigerated by the refrigeration equipment 53 is transported to the first coil 513 through the input pipe 511. Then, the first coil 513 can cool the roller 58. During the transport process, the capacitor diaphragm will come into contact with the cooled roller 58, so that the two rollers 58 can cool the two sides of the capacitor diaphragm. In addition, the cold air generated by the first coil 513 will also diffuse into the inner cavity of the roller 58. It will be dispersed into the upper cover 51 and the lower cover 52 through the vent 59, so as to collect the cold air and continuously cool the capacitor diaphragm, thereby improving the cooling effect. The liquid after heat exchange will flow back to the output pipe 512 through the second coil 514, and finally return to the refrigeration equipment 53 through the output pipe 512 for cooling again, thereby realizing the function of cyclic refrigeration.

[0031] During adjustment, when cooling is required for capacitor films of different thicknesses, the capacitor film is first wound again according to the above steps. Then, the third cylinder 62 is started, which pushes the U-shaped frame 61 to rotate on the frame 1 through the movable part 66, thereby raising the height of the rotating rod 63 and squeezing the capacitor film to achieve a tensioning effect. Through the purpose of tensioning, the capacitor film can be tightened and adhered to the two roller cylinders 58, thereby achieving cooling.
