Description

Technical Field

[0001] This utility model relates to the technical field of electrode foil processing equipment, and in particular to an electrode foil surface rolling and leveling mechanism. Background Technology

[0002] As a crucial raw material for aluminum electrolytic capacitors, the surface quality of electrode foil directly affects the overall performance of the capacitor. The surface flatness and uniformity of the electrode foil are key indicators of its quality. Insufficient surface flatness can lead to uneven electric field distribution within the capacitor, resulting in increased leakage current and reduced stability and lifespan. Conversely, poor surface uniformity affects the capacitor's capacitance accuracy and performance consistency, ultimately weakening the reliability of electronic equipment. Therefore, improving the surface flatness and uniformity of electrode foil through rolling and leveling processes is a critical step in ensuring product performance.

[0003] Most existing electrode foil calendering and leveling mechanisms rely on manual cleaning of the roll surface. When dust or residual particles adhere to the calendering roll during operation, the machine needs to be stopped and the operator wipes it or cleans it with simple tools. This method is not only time-consuming and labor-intensive, seriously affecting production efficiency, but also makes it difficult to ensure thoroughness and uniformity of manual cleaning. Some residues often remain on the roll surface, which continues to negatively affect the subsequent calendering effect and makes it difficult to meet the requirements of high-quality production. Dust and particles accumulate on the roll surface. If they are not removed in time, these residues will gradually be compacted to form stubborn stains, increasing the difficulty of cleaning and reducing product consistency and finished product qualification rate.

[0004] In addition, some existing cleaning devices lack the necessary buffering and protection mechanisms when in contact with the calendering rolls. During operation, the cleaning components exert a large impact and friction force on the roll surface, which can easily cause wear or scratches on the roll surface, damaging its smoothness and precision. Damage to the roll surface will not only directly aggravate defects such as indentations and scratches on the electrode foil surface, but also shorten the service life of the calendering rolls, leading to increased production costs and creating a vicious cycle. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose an electrode foil surface calendering and leveling mechanism to solve the problems of incomplete cleaning and easy damage to the roller surface in the traditional electrode foil surface calendering and leveling mechanism.

[0006] To achieve the above objectives, this utility model provides an electrode foil surface rolling and leveling mechanism, comprising: a working platform; A calendering and leveling assembly is installed on one side of the working platform. Support frames are symmetrically installed on one side of the working platform. An upper calendering roll and a lower calendering roll are rotatably installed between the two support frames. The upper calendering roll and the lower calendering roll are arranged parallel to each other and are used to calender and level the electrode foil. A power assembly is installed on one side of the work platform and is used to provide power. The power assembly includes several support columns installed on one side of the work platform. A reciprocating screw is rotatably installed between the support columns. A small motor is provided on one side of the support columns. One end of the reciprocating screw is connected to the output end of the small motor. A cleaning assembly, connected to the power assembly, is used to clean dust or residual particles from the surfaces of the upper and lower calendering rolls. The cleaning assembly includes connecting strips movably mounted on the reciprocating lead screw, with several mounting plates installed between the two connecting strips. Several brush bristles are mounted on one side of each mounting plate, and these bristles contact the surfaces of the upper and lower calendering rolls to effectively clean dust or residual particles adhering to the calendering roll surfaces, thereby ensuring roll surface smoothness and calendering quality.

[0007] Preferably, the calendering and leveling assembly includes a plurality of first hydraulic cylinders mounted on the support frame, the output end of the first hydraulic cylinders is equipped with bearings, both ends of the upper calendering roller are mounted in the bearings, a main motor is provided on one side of one of the support frames, a second gear is mounted on the output end of the main motor, a first gear is mounted on one end of the lower calendering roller, and the first gear and the second gear are connected by a belt.

[0008] Preferably, the power assembly includes several sliders slidably mounted between two support columns, a reciprocating screw rotatably mounted between two opposing sliders, a small motor mounted on one side of one of the sliders, and several second hydraulic cylinders provided on one side of the working platform, with the output end of the second hydraulic cylinders connected to the sliders.

[0009] Preferably, a groove is provided on one side of the support column, and the slider is slidably installed in the groove.

[0010] Preferably, the cleaning assembly includes several connecting blocks movably mounted on a reciprocating lead screw, several sliding rods fixedly mounted between two sliders, connecting blocks slidably mounted on the sliding rods, and connecting strips connected to one side of the connecting blocks.

[0011] Preferably, a plurality of connecting plates are fixedly installed on one side of the connecting strip, a connecting shaft is fixedly installed on one side of the connecting plate, and connecting hoops are fixedly installed on the symmetrical sides of the mounting plate, the connecting hoops being rotatably connected to the connecting shaft.

[0012] Preferably, a connecting piece is fixedly installed on one side of the mounting plate, and a fixing plate is fixedly installed on both symmetrical sides of the connecting piece. Several return springs are installed on both symmetrical sides of the fixing plate.

[0013] Preferably, the limiting plate is symmetrically arranged with the connecting shaft as the center, and the side of the limiting plate near the fixing plate has an arc-shaped structure.

[0014] The beneficial effects of this utility model are: 1. This electrode foil surface calendering and leveling mechanism, equipped with a power component and a cleaning component, achieves automated cleaning of the calendering roll surface. It avoids surface indentations, scratches, or uneven calendering caused by dust or residual particles adhering to the calendering roll surface, thus significantly improving the flatness of the electrode foil surface and product consistency. The power component, through the cooperation of a hydraulic cylinder and a reciprocating screw, can flexibly adjust the working stroke of the cleaning component, ensuring the cleaning range fully covers the upper and lower calendering rolls, guaranteeing thorough cleaning, and improving operational convenience and flexibility. The cleaning component uses a brush bristle elastically attached to the calendering roll, effectively buffering the impact during the cleaning process under the synergistic action of a return spring and a limit plate. This ensures cleaning intensity while avoiding excessive wear on the roll surface, extending the equipment's service life. The overall structure maintains the calendering and leveling function while reducing the frequency of manual downtime for cleaning, improving production efficiency and equipment stability, and possesses good practicality and promotional value.

[0015] 2. This electrode foil surface calendering and leveling mechanism, equipped with calendering and leveling components, enables precise adjustment of the gap and pressure between the upper and lower calendering rolls under the action of the first hydraulic cylinder. This ensures that the electrode foil receives uniform and stable calendering as it passes through the roll gap, effectively improving the flatness and thickness consistency of the electrode foil surface and avoiding wrinkling, warping, or localized thickness unevenness caused by uneven pressure. Simultaneously, the upper and lower calendering rolls operate smoothly under bearing support, maintaining good synchronization and stability during continuous operation, reducing equipment vibration and the risk of damage to the electrode foil. Furthermore, through the control of the hydraulic cylinder, the calendering process can flexibly adapt to electrode foils of different specifications or thicknesses, improving the adaptability and adjustment range of the device. Overall, it not only improves the processing quality and yield of the electrode foil but also extends the service life of the equipment, reduces manual intervention and rework probability, and has good production efficiency and application value.

[0019] 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.

[0021] like Figures 1 to 5 As shown, the electrode foil surface rolling and leveling mechanism includes: a working platform 1; a rolling and leveling assembly, which is installed on one side of the working platform 1, with support frames 6 symmetrically installed on one side of the working platform 1, and an upper rolling roller 4 and a lower rolling roller 5 rotatably installed between the two support frames 6. The upper rolling roller 4 and the lower rolling roller 5 are arranged parallel to each other and are used to roll and level the electrode foil; a power assembly, which is installed on one side of the working platform 1 and is used to provide power. The power assembly includes several support columns 15 installed on one side of the working platform 1, with reciprocating screws 12 rotatably installed between the support columns 15. A small motor 17 is provided on one side, and one end of the reciprocating screw 12 is connected to the output end of the small motor 17; a cleaning component is connected to the power component. The cleaning component is used to clean dust or residual particles on the surface of the upper calendering roll 4 and the lower calendering roll 5. The cleaning component includes a connecting strip 19 movably mounted on the reciprocating screw 12. Several mounting plates 20 are installed between the two connecting strips 19. Several bristles 21 are installed on one side of the mounting plate 20. The bristles 21 contact the surface of the upper calendering roll 4 and the lower calendering roll 5 to effectively clean the dust or residual particles attached to the surface of the calendering rolls, so as to ensure the smoothness of the roll surface and the calendering quality. In use, the electrode foil surface calendering and leveling mechanism transports the electrode foil through the upper calendering roller 4 and lower calendering roller 5 positioned between the support frame 6. The upper and lower calendering rollers are parallel to each other and are driven to rotate by the main motor 9. The output of the main motor 9 is connected to the first gear 8 at one end of the lower calendering roller 5 via the second gear 10 and belt 7, thereby driving the lower calendering roller 5 to rotate and propelling the electrode foil forward through friction with it. Simultaneously, the upper calendering roller 4, driven by the first hydraulic cylinder 2, can adjust the pressure of the electrode foil. The bearing 3 at the output of the hydraulic cylinder ensures the stable rotation and position adjustment of the upper calendering roller 4, ensuring uniform calendering and leveling of the electrode foil as it passes between the two rollers. The cleaning component cleans the surfaces of the upper calendering roller 4 and lower calendering roller 5, removing dust or residual particles to prevent affecting the calendering effect and the surface quality of the electrode foil. This achieves continuous calendering and leveling of the electrode foil, effectively improving its surface flatness and consistency.

[0022] like Figure 4 , Figure 5 As shown, the power assembly includes several sliders 11 slidably mounted between two support columns 15, a reciprocating screw 12 rotatably mounted between two opposing sliders 11, a small motor 17 mounted on one side of one of the sliders 11, and several second hydraulic cylinders 13 arranged on one side of the working platform 1, with the output end of the second hydraulic cylinders 13 connected to the slider 11; a groove 14 is provided on one side of the support column 15, and the slider 11 is slidably mounted in the groove 14; the cleaning assembly includes several connecting blocks 18 movably mounted on the reciprocating screw 12, several slide rods 16 fixedly mounted between the two sliders 11, the connecting blocks 18 slidably mounted on the slide rods 16, and a connecting strip 19 connected to one side of the connecting block 18; A plurality of connecting plates 28 are fixedly installed on one side of the connecting strip 19, and a connecting shaft 27 is fixedly installed on one side of the connecting plate 28. Connecting hoops 25 are fixedly installed on both sides of the mounting plate 20, and the connecting hoops 25 are rotatably connected to the connecting shaft 27. A connecting piece 22 is fixedly installed on one side of the mounting plate 20, and a fixing plate 24 is fixedly installed on both sides of the connecting piece 22. A plurality of return springs 23 are installed on both sides of the fixing plate 24. A limiting plate 26 is symmetrically fixedly installed on one side of the connecting plate 28. The end of the return spring 23 away from the fixing plate 24 is fixedly connected to one side of the limiting plate 26. The limiting plate 26 is symmetrically arranged with the connecting shaft 27 as the center, and the side of the limiting plate 26 near the fixing plate 24 has an arc-shaped structure. During operation, the upper calendering roller 4 and lower calendering roller 5 may become contaminated with dust or residual particles. First, the rotation speed of the upper calendering roller 4 and lower calendering roller 5 is adjusted to maintain a suitable operating state for cleaning. Then, a small motor 17 is started, driving the reciprocating lead screw 12 to rotate, thereby driving the connecting block 18 mounted on the lead screw to reciprocate. Simultaneously, the second hydraulic cylinder 13, connected to the slider 11, adjusts the linear stroke of the slider 11, ensuring that the cleaning assembly covers the entire working area of ​​the upper calendering roller 4 and lower calendering roller 5 during reciprocating motion, ensuring that the roller surfaces are cleaned. During the cleaning process, the bristles 21 on the mounting plate 20 continuously contact the surface of the calendering rollers, effectively removing the attached dust or residual particles, ensuring the smoothness of the roller surface and the calendering quality. To prevent the bristles from becoming contaminated... Excessive friction is generated between the bristles 21 and the roller surface. The two sides of the mounting plate 20 are rotatably connected to the connecting shaft 27 via connecting clamps 25. When the bristles 21 are subjected to resistance from the roller surface, the mounting plate 20 can deflect slightly. The return spring 23 is compressed and stores energy under the action of the limiting plate 26, and releases energy after the resistance disappears, restoring the mounting plate 20 to its original position. This ensures that the bristles 21 always maintain elastic contact without excessive wear. At the same time, the arc-shaped structure of the limiting plate 26 can play a buffering and guiding role when the mounting plate 20 deflects, effectively reducing the direct impact between the fixing plate 24 and the limiting plate 26, improving the smoothness and service life of the cleaning action. The cleaning component realizes automatic reciprocating cleaning and elastic reset of the calender roller surface, keeping the roller surface clean at all times, thereby ensuring the stability of the electrode foil calendering and leveling process and the quality of the finished product.
