Description
Technical Field
[0001] This utility model relates to the field of aluminum foil processing technology, specifically to an aluminum foil processing device for aluminum electrolytic capacitors. Background Technology
[0002] Aluminum electrolytic capacitors are made by inserting a bent aluminum strip as the positive electrode into an aluminum cylinder as the negative electrode, which contains liquid electrolyte. They also require DC voltage treatment to form an oxide film on the positive electrode as the dielectric. They are characterized by large capacity, but also have high leakage current and poor stability. They have positive and negative polarity and are suitable for power supply filtering or low-frequency circuits. When using them, the positive and negative terminals should not be reversed.
[0003] Currently, some existing aluminum foil processing devices for aluminum electrolytic capacitors rely on workers to wind the aluminum foil using a single winding roller. However, the single winding roller may generate a high load while rotating for a long time, which can lead to serious wear and tear on the internal machinery of the winding roller. This can cause the winding roller to jam or become uneven during the winding process, reducing the efficiency of aluminum foil winding. To address these issues, we will innovate the technology based on the existing devices. Utility Model Content

A take-up motor 23 is connected, and a power supply, wires, controller, and microcomputer structure are provided to match the take-up motor 23. Since the motor is not a major structure, it will not be described in detail. The output end of the take-up motor 23 is fixedly connected to a rotating shaft through a coupling. A limit block 25 is fixedly connected to the outer wall of the rotating shaft. A bearing plate 12 is fixedly connected to the top of the base 1. The bearing plate 12 is located between two sets of brackets 13. A motor 3 for power output is fixedly connected to the surface of the left front support column 2. The motor 3 is set up in the same way as the take-up motor 23. The output end of the motor 3 is fixedly connected to a rotating shaft through a coupling. A rotating rod 11 is fixedly connected to the outer wall of the rotating shaft. The end of the rotating rod 11 away from the output end of the motor 3 rotates through the support column 2 and extends to its outside. A rotation adjustment device is provided on the rotating rod 11.
[0023] Please refer to Figure 5 The rotation adjustment device includes a power rod 6. The right side of the power rod 6 is fixedly connected to the end of the rotating rod 11 away from the output end of the motor 3. The end of the power rod 6 away from the rotating rod 11 is fixedly connected to a drive wheel 5. A groove is provided on the drive wheel 5. A rotating column 7 is fixedly connected to the side of the power rod 6 near the drive wheel 5.
[0024] Please refer to Figure 1 A column 8 is fixedly connected to the top of the base 1. A first rotating shaft 16 is rotatably connected to one side of the column 8. A cam 9 is fixedly connected to the side of the first rotating shaft 16 away from the column 8. The surface of the cam 9 has multiple arc surfaces that match the surface of the drive wheel 5. The surface of the cam 9 has multiple sliding grooves 10. The rotating column 7 is slidably connected to the inside of the sliding grooves 10.
[0025] Please refer to Figure 3 The side of cam 9 away from the first rotating shaft 16 is fixedly connected to the right turntable 15. By rotating cam 9, cam 9 can drive the right turntable 15 to rotate. The right turntable 15 can drive the left turntable 15 to rotate synchronously through the connecting rod 18. Multiple symmetrical rotating grooves 19 are opened on the opposite sides of the two turntables 15. The interior of the rotating groove 19 is rotatably connected to the second rotating shaft 17. The end of the second rotating shaft 17 away from the rotating groove 19 is fixedly connected to the winding roller 4 for winding aluminum foil. The end of the left second rotating shaft 17 away from the winding roller 4 is fixedly connected to the rotating block 24. The limiting block 25 is slidably connected to the interior of the rotating block 24.
[0026] The worker pulls the aluminum foil wound on the feed roller onto the upper take-up roller 4. The take-up motor 23 is started via an external control device. The output of the take-up motor 23 drives the take-up roller 4 to rotate via a shaft, thus winding the aluminum foil. Once enough aluminum foil has been wound onto the upper take-up roller 4, the worker turns off the take-up motor 23. Then, the worker starts the motor 3 via the controller and microcomputer structure. The output of the motor 3 drives the rotating rod 11 to rotate via a shaft. The rotating rod 11 drives the power rod 6 to rotate, which in turn drives the drive wheel 5 to rotate. The surface of the drive wheel 5 contacts the arc surface on the cam 9, and the arc surface of the drive wheel 5... Limiting the rotation makes it smoother and more stable. At the same time, the power rod 6 drives the rotating column 7 to slide inside the sliding groove 10, which allows the cam 9 to rotate intermittently under force. The cam 9 drives the turntable 15 to rotate, and the turntable 15 can rotate multiple take-up rollers 4. By adjusting the rotation of multiple take-up rollers 4, multiple take-up rollers 4 can be used in turn, thereby maintaining the smoothness of the take-up process and improving the overall production efficiency. At the same time, the alternating work of multiple take-up rollers 4 distributes the workload of each take-up roller 4, reduces the mechanical wear caused by continuous high-intensity operation, and thus improves the durability and operational stability of the equipment.
[0027] Please refer to Figure 4 Each of the two support rings 14 has a movable groove 20 on its opposite side, and the interior of the movable groove 20 is connected to the interior of the rotating groove 19.
[0028] The operator starts motor 3 via the controller and microcomputer structure. The output of motor 3 drives rotating rod 11 to rotate via a rotating shaft. Rotating rod 11 drives power rod 6 to rotate, which in turn drives drive wheel 5 to rotate. The surface of drive wheel 5 contacts the arc surface on cam 9, which limits the rotation of drive wheel 5, making its rotation smoother and more stable. At the same time, power rod 6 drives rotating column 7 to slide inside sliding groove 10, which allows cam 9 to rotate intermittently under force. Cam 9 drives turntable 15 to rotate, which in turn drives take-up roller 4 to rotate, thus winding up the completed take-up roller. 4. When rotated to the bottom, the completed winding roller 4 slides out through the moving groove 20 and falls onto the carrying plate 12. By sliding the completed winding roller 4 out of the moving groove 20, it is convenient for the staff to take out the completed winding roller 4 as a whole and place it without having to disassemble the winding device extensively. This effectively simplifies the operation process, reduces the difficulty of operation, and allows for the installation of a new winding roller 4 in a short time. This ensures the continuity of the aluminum foil winding process, reduces production downtime, significantly improves winding efficiency, reduces manual labor intensity, and enhances the safety and convenience of operation.
[0029] Working principle: For this type of aluminum foil processing device for aluminum electrolytic capacitors, the operator first pulls the aluminum foil from the feeding roller onto the upper winding roller 4. The cutting mechanism is started by an external control device to cut the aluminum foil. Then, the winding motor 23 is started by an external control device. The output end of the winding motor 23 drives the upper winding roller 4 to wind the aluminum foil through a rotating shaft. When the upper winding roller 4 has finished winding, the motor of the upper winding roller 4 is turned off. The operator starts the motor 3 through the controller and microcomputer structure. The output end of the motor 3 drives the power rod 6 and the drive wheel 5 to rotate through the rotating shaft. The power rod 6 drives the rotating column 7 to rotate, causing the cam 9 to rotate intermittently. The cam 9 drives the turntable 15 to rotate, and the turntable 15 drives the winding roller 4 to rotate. When the winding roller 4 has finished winding and rotated to the bottom, it can slide out of the interior of the rotating groove 19 through the moving groove 20 and fall onto the carrying plate 12 for easy storage by the operator.
