Description

Technical Field

[0001] This utility model relates to the field of aluminum foil technology, specifically to a conductive roller for producing aluminum foil for capacitors. Background Technology

[0002] In the production of aluminum foil capacitors, conductive rollers are a crucial component, primarily used for transmitting current and aluminum foil. However, under high-speed operation and high-voltage current, significant frictional heat is generated between the conductive rollers and the aluminum foil, leading to localized overheating. When the temperature exceeds a certain limit, sparks can occur on the aluminum foil surface, severely impacting product quality and even posing safety hazards.

[0003] Traditional conductive rollers typically employ a solid metal structure, resulting in poor heat dissipation and making it difficult to effectively address the aforementioned problems. Therefore, a novel conductive roller structure is urgently needed to solve the technical issue of excessively high temperatures during processing, which can cause sparks to form on the aluminum foil surface. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a conductive roller for capacitor aluminum foil production that can reduce temperature and prevent sparks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a conductive roller for producing aluminum foil for capacitors, comprising an aluminum roller, the aluminum roller being closed at both ends and having an inlet and an outlet respectively, and being hollow inside. Connecting shafts are provided at both ends of the aluminum roller, the connecting shafts being hollow inside and communicating with the interior of the aluminum roller. The innovation lies in: a connecting pipe is provided inside the aluminum roller, the left and right ends of the connecting pipe being connected to the inlet and the outlet respectively, and multiple inlet holes are provided near the inlet of the connecting pipe, and multiple outlet holes are provided near the outlet of the connecting pipe. Multiple grooves are provided in the middle of the connecting pipe, and a bearing is sleeved in each groove, and a fan blade is provided on each bearing. Multiple spray holes are provided on the side wall of the groove, the spray holes being located in the direction of the cooling water flow and aligned with the fan blade.

[0006] Furthermore, both the inlet and outlet holes are arranged in an inclined and circular array, with the inlet hole inclined toward the liquid inlet and the outlet hole inclined toward the liquid outlet.

[0007] Furthermore, the injection holes are all arranged in an inclined and circular array, and there is an angle between them and the fan blades, the angle being between 30° and 60°.

[0008] Furthermore, the aluminum roller is coated with a conductive layer, which is silver.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows:

[0010] This invention, by incorporating a rotating fan blade, alters the flow of liquid within the aluminum roller, accelerating its heat exchange process. This results in significantly less heat generation by the conductive roller, increased operating speed, reduced losses, fewer foil breaks, more stable production, and improved product qualification rate.

[0017] 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 the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0018] See Figure 1-3A conductive roller for producing aluminum foil for capacitors includes an aluminum roller 1, which is closed at both ends and has an inlet 2 and an outlet 3 respectively. The roller is hollow inside. Connecting shafts 4 are provided at both ends of the aluminum roller 1. The connecting shafts 4 are hollow inside and communicate with the interior of the aluminum roller 1. A connecting pipe 5 is provided inside the aluminum roller 1. The left and right ends of the connecting pipe 5 are connected to the inlet 2 and the outlet 3 respectively. Multiple inlet holes 6 are provided near the inlet of the connecting pipe, and multiple outlet holes 7 are provided near the outlet of the connecting pipe. Multiple grooves 8 are provided in the middle of the connecting pipe 5, and a bearing 9 is sleeved in each groove. A fan blade 10 is provided on each bearing 9. Multiple spray holes 11 are provided on the side wall of the groove 8. The spray holes 11 are located in the direction of cooling water flow and are aligned with the fan blade 10. Specifically, cooling water enters the aluminum drum 2 through the connecting shaft 4 and the liquid inlet 2. Part of the water enters the aluminum drum 1 through the inlet hole 6 and then exits through the outlet hole 7 and the liquid outlet 3, carrying away heat and cooling the aluminum drum 1. The other part of the cooling water enters the connecting pipe 5 and is transported along the connecting pipe 5. When it passes through the spray hole 11, it is sprayed out from the spray hole 11 and sprayed onto the fan blade 10. The fan blade 10 rotates, changing the liquid flow mode inside the aluminum drum, accelerating its heat exchange process, so that the conductive roller generates much less heat, increases the operating speed, reduces losses, reduces foil breakage, stabilizes production, and improves the product qualification rate.

[0019] In this embodiment, both the inlet hole 6 and the outlet hole 7 are arranged in an inclined and circular array. The inlet hole 6 is inclined toward the liquid inlet 2 to guide the cooling water and facilitate its entry into the area between the connecting pipe 5 and the aluminum roller 2. The outlet hole 7 is inclined toward the liquid outlet 3 to facilitate the coolant entering the connecting pipe 5 and finally being discharged from the liquid outlet 3.

[0020] In this embodiment, the injection holes 11 are all arranged at an angle and in a circular array, and there is an angle between them and the fan blade 10, which is between 30° and 60°. The injection holes 11 are tilted to align with the fan surface of the fan blade, and the angled arrangement ensures that the injection is directed onto the fan surface of the fan blade, which is beneficial for the rotation of the fan blade.

[0021] In this embodiment, the aluminum roller 1 is coated with a conductive layer, which is silver, to improve conductivity.

[0022] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
