Description

Technical Field

[0001] This utility model relates to the field of foil forming technology, and in particular to a conveying device for aluminum foil forming. Background Technology

[0002] The aluminum foil formation transport device is a core piece of specialized equipment in the formation process of an aluminum electrolytic capacitor production line. It plays a crucial role in the continuous, stable, and precise transport and handling of aluminum foil (bright foil or cathode foil) in a highly corrosive electrolyte environment. Its core function is to automate the movement of the aluminum foil between series formation holes, ensuring the high precision and constancy of the foil's path, tension, speed, and position (especially immersion depth). Its design and operation must overcome numerous technical challenges, including strong acid corrosion, high voltage conduction (via conductive rollers), maintaining surface cleanliness, and preventing contamination and cross-contamination. It features high-precision tension control, excellent corrosion resistance, stable conductivity, and high reliability. The performance of the aluminum foil formation transport device directly determines the efficiency of the formation process, the quality and consistency of the oxide film, and thus profoundly affects the final capacitor's capacity, loss, lifespan, reliability, and production yield. It is an indispensable key piece of equipment in the production of modern high-quality aluminum electrolytic capacitors.

[0003] Existing aluminum foil forming and conveying devices place the rolled aluminum foil on an unwinding roller, which, driven by a motor, rotates the foil. The foil then passes through two electrolytic cells in the middle of the device for forming. After drying, the rewinding roller at the end of the device rotates the formed foil to form a rolled aluminum foil. However, if the tension of the foil changes while it is being conveyed, manual intervention is required, stopping the equipment to adjust the two motors, wasting manpower and equipment operating time.

[0014] 1.

[0024] Real reference Figures 1-2This utility model provides an embodiment of a conveying device for aluminum foil formation processing, comprising an unwinding roller 1, on which untreated rolled aluminum foil is placed. A support frame 3 is provided on the outer wall of the unwinding roller 1, supporting the entire device. A take-up roller 9 is provided on the upper surface of the other end of the support frame 3, which winds up the formed aluminum foil. A first motor 2 is provided on one side of the outer wall of the unwinding roller 1. A first drive wheel is fixedly connected to the output end of the first motor 2, and a first driven wheel is fixedly connected to one end of the unwinding roller 1. A first belt drives the first drive wheel and the first driven wheel. The first motor 2 is driven by a first drive wheel. A drive wheel drives a first driven wheel and a belt to rotate the unwinding roller shaft 1. A second motor 10 is installed on one side of the outer wall of the take-up roller shaft 9. The output end of the second motor 10 is fixedly connected to a second drive wheel, and one end of the take-up roller shaft 9 is fixedly connected to a second driven wheel. A second belt is connected between the second drive wheel and the second driven wheel. The second motor 10 drives the first driven wheel and the belt to rotate the take-up roller shaft 9. A tension adjustment mechanism is installed on the upper middle side of the support frame 3. The tension adjustment mechanism includes a gear 11. A first support block 13 is rotatably connected to the outer wall of the gear 11. The gear 11 rotates on the first support block 13. The support block 13 is positioned below the middle part of the upper part of the support frame 3. A second support block 14 is provided on one side of the outer wall of the first support block 13. The second support block 14 is fixedly connected to the middle part of the upper part of the support frame 3. A rack 12 is slidably connected to the upper surface of the second support block 14. The rack 12 slides on the second support block 14. A gear 11 meshes with the rack 12. The rotation of the gear 11 drives the rack 12 to slide. An adjusting roller shaft 15 is rotatably connected to the upper side of the outer wall of the second support block 14. The adjusting roller shaft 15 moves up and down with the rack 12. A rotating handle 5 is fixedly connected to the outer wall of the gear 11. The gear 11 rotates together with the rotating handle 5. When running... When the aluminum foil becomes loose or excessively tight during the process, the adjusting handle 5 drives the adjusting roller shaft 15 to move up and down to a suitable distance. The adjusting roller shaft 15 is then fixed by bolts to the rack 12 from the second support block 14. During the forward movement of the aluminum foil, the tightness will change. Being too loose or too tight will have a negative impact on the transmission of the aluminum foil. The tightness adjustment mechanism can finely adjust the tightness of the aluminum foil to prevent it from becoming loose or breaking. This saves manpower and increases the working time of the equipment. A foil pressing mechanism is provided on one side of the outer wall of the unwinding roller shaft 1, an electrolysis mechanism is provided on one side of the outer wall of the second support block 14, and a drying mechanism is provided on one side of the outer wall of the winding roller shaft 9.

[0025] Real reference Figures 1-3The foil pressing mechanism includes a lower pressure plate 4, which passes over the aluminum foil as it moves forward. The lower pressure plate 4 is located on one side of the outer wall of the second support block 14. The two sides of the lower pressure plate 4 are fixedly connected to the upper middle part of the support frame 3. A second hydraulic cylinder 18 is installed at the top of the support frame 3. An upper pressure plate 19 is fixedly connected to the output end of the second hydraulic cylinder 18, allowing the upper pressure plate 19 to move up and down. An inclined plate 17 is fixedly connected to one end of the lower pressure plate 4, providing support for the aluminum foil. Fixed blocks 22 are fixedly connected to both sides of the outer wall of the lower pressure plate 4, guiding the forward-moving aluminum foil. Electric slide rails 20 are fixedly connected to both sides of the outer wall of the lower pressure plate 4, with the middle of the outer wall of the electric slide rails 20 slidably connected. There is a wiping disc 21 and an electric slide rail 20 connected to an external power source. The wiping disc 21 is controlled to flatten the aluminum foil and prevent wrinkles. The top of the support frame 3 is equipped with a first hydraulic cylinder 16. The output end of the first hydraulic cylinder 16 is fixedly connected to a clamping roller shaft. The first hydraulic cylinder 16 controls the clamping roller shaft and the inclined plate 17 to clamp the aluminum foil. When the rolled aluminum foil at the unwinding roller shaft 1 is consumed and a new rolled aluminum foil is replaced, the old aluminum foil stays on the lower pressure plate 4. The new aluminum foil passes through the inclined plate 17 and reaches above the old aluminum foil. After the action of the second hydraulic cylinder 18, the upper pressure plate 19 and the lower pressure plate 4 close, pressing the old aluminum foil and the new aluminum foil together, saving the time that the new aluminum foil still needs to go through a processing process to reach the take-up roller shaft 9.

[0026] Real reference Figures 1-5 The electrolysis mechanism includes a first electrolytic cell 6, which is disposed on one side of the outer wall of the adjusting roller 15. A second electrolytic cell 7 is disposed on one side of the outer wall of the first electrolytic cell 6. The aluminum foil undergoes formation treatment through the first electrolytic cell 6 and the second electrolytic cell 7. A first roller group 25 is rotatably connected inside the first electrolytic cell 6, and a second roller group 26 is rotatably connected inside the second electrolytic cell 7. The first roller group 25 and the second roller group 26 enable the aluminum foil to enter and exit the first electrolytic cell 6 and the second electrolytic cell 7 from a fixed direction.

[0027] Real reference Figures 1-4 The drying mechanism includes a drying chamber 8, which is the location for drying aluminum foil. The drying chamber 8 is located on one side of the outer wall of the take-up roller 9. The drying chamber 8 has an inlet and outlet 23. The aluminum foil enters from the inlet and outlet 23 at one end. A hot air blower 24 is provided at the bottom of the drying chamber 8. After being dried by the hot air blower 24, the aluminum foil is output from the inlet and outlet 23 at the other end. Then, the take-up roller 9 controlled by the second motor 10 rolls up the processed aluminum foil.

[0028] Working principle: Untreated roll aluminum foil is placed on unwinding roller 1. Under the action of the first motor 2, unwinding roller 1 drives the roll aluminum foil to rotate. The aluminum foil starts from unwinding roller 1, passes through inclined plate 17, and the first hydraulic cylinder 16 controls clamping roller 16 and inclined plate 17 to clamp the aluminum foil. The aluminum foil on the lower pressure plate 4 is guided by fixing blocks 22 on both sides of the lower pressure plate 4. On the electric slide rail 20 with external power supply, smearing plate 21 flattens the aluminum foil. When the roll aluminum foil on unwinding roller 1 is consumed and replaced, the old aluminum foil stays above the lower pressure plate 4, and the new aluminum foil passes through inclined plate 17 to reach above the old aluminum foil. Under the action of the second hydraulic cylinder 18, upper pressure plate 19 and lower pressure plate 4 close, pressing the old aluminum foil and the new aluminum foil together. The first hydraulic cylinder 16, the second hydraulic cylinder 18 and the lower pressure plate 4 are fixed on the support frame 3. Then the aluminum foil passes through adjusting roller 15, which is fixed to rack 12 and supported by second support block 1. 4. The movement is restricted to vertical. The first support block 13 fixes the gear 11. The gear 11 rotates together with the rotating handle 5. The rotation of the gear 11 drives the rack 12 to move up and down. When the aluminum foil is loose or too tight during operation, the rotating handle 5 is adjusted to drive the adjusting roller 15 to move up and down to a suitable distance. The rack 12 is fixed from the second support block 14 by bolts, thereby fixing the adjusting roller 15. The first support block 13 and the second support block 14 are fixed on the support frame 3. The aluminum foil then passes through the first electrolytic cell 6 and the second electrolytic cell 7. The first roller group 25 and the second roller group 26 allow the aluminum foil to enter and exit the first electrolytic cell 6 and the second electrolytic cell 7 from a fixed direction. After the aluminum foil completes the formation process in the electrolytic cell, it enters the drying chamber 8 from the inlet and outlet 23 and is dried by the hot air fan 24 below the drying chamber 8. It is then output from the inlet and outlet 23 at the other end. Then, the winding roller 9 controlled by the second motor 10 rolls up the formed aluminum foil.
