[0019] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0020] Example 1: An aluminum foil winding device for electrolytic capacitors, referring to Figures 1 to 7 , including a base 1, and also including: The winding assembly 2 is arranged inside the base 1. A limiting mechanism 3 is provided inside the base 1; Among them, the limiting mechanism 3 includes a limiting rod 301 fixedly connected to the inside of the base 1, and two limiting plates 302 are slidingly sleeved on the surface of the limiting rod 301. Connecting plates 303 are fixedly installed on the opposite sides of the two limiting plates 302. A motor 304 is fixedly installed on the top of the base 1, and a screw rod 305 is fixedly installed on the output end of the motor 304. A threaded plate 306 is threadedly sleeved on the surface of the screw rod 305, and the threaded plate 306 is hinged to the connecting plate 303 through a hinge rod 307.

[0021] By adopting the above technical solution, the operator installs the winding assembly 2 inside the base 1, and then drives the winding assembly 2 to rotate. During the rotation of the winding assembly 2, the aluminum foil can be rolled up. During the winding process of the winding assembly 2, the motor 304 can be driven to rotate the screw rod 305. Since the screw rod 305 is threadedly connected to the threaded plate 306, when the screw rod 305 rotates, the threaded plate 306 will drop on the surface of the screw rod 305. Since the threaded plate 306 is hinged to the connecting plate 303 through the hinge rod 307, the moving threaded plate 306 will drive the hinged rod 307 to rotate, and the rotating hinged rod 307 will pull the two connecting plates 303 to move relative to each other, and the connecting plates 303 will pull the two limit plates 302 to move on the surface of the limit rod 301, and the surfaces of the limit plates 302 will contact the two ends of the winding component 2 and the two ends of the aluminum foil, so that the limit plates 302 can limit the aluminum foil, and finally the limit plates 302 can effectively limit the moving aluminum foil by driving the motor 304, thereby ensuring that the aluminum foil is evenly distributed when the winding component 2 is wound, thereby greatly improving the winding quality and efficiency.

[0022] Specifically, the winding assembly 2 includes a driving member 201 fixedly connected to the top of the base 1, and a fixed shell 202 is fixedly installed at the output end of the driving member 201. A main winding roller 203 is provided inside the base 1, and one end of the main winding roller 203 is fixedly connected to the fixed shell 202 by a thread, and a guide roller 204 is rotatably connected to the top of the base 1.

[0023] By adopting the above technical solution and the design of the winding assembly 2, the main winding roller 203 can be installed inside the base 1, and one end of the main winding roller 203 can be fixed to the fixed shell 202 by bolts, and the other end of the main winding roller 203 can be placed on the support frame. Then, the aluminum foil can be wound around the surface of the guide roller 204, and one end of the aluminum foil can be connected to the surface of the main winding roller 203. Then, the driving member 201 can be driven to rotate the fixed shell 202 and the main winding roller 203. During the rotation, the aluminum foil can be wound, and the moving aluminum foil will drive the guide roller 204 to rotate, thereby making the aluminum foil move more smoothly.

The adjustment mechanism 5 includes a fixed ring 501 fixedly connected to the top of the base 1. An adjustment roller 502 is slidably connected to the inside of the fixed ring 501. The adjustment roller 502 is elastically connected to the fixed ring 501 via an elastic member 503. A steel wire rope 504 is slidably connected to the inside of the fixed ring 501, and one end of the steel wire rope 504 is fixedly connected to the surface of the adjustment roller 502. A worm gear 505 is rotatably connected to the top of the base 1. A capstan 506 is fixedly mounted on one side of the worm gear 505, and the other end of the steel wire rope 504 is fixedly connected to the surface of the capstan 506. The driving assembly 6 is disposed at the top of the base 1 and is capable of driving the worm gear 505 to rotate.

[0025] By adopting the above technical solution and the design of the adjustment mechanism 5, the driving assembly 6 can be driven during the winding process of the main winding roller 203, and the driving assembly 6 will drive the worm gear 505 to rotate, and the worm gear 505 will drive the capstan 506 to rotate. Since the other end of the wire rope 504 is fixedly connected to the capstan 506, when the capstan 506 rotates, the wire rope 504 will be wound around its surface, and the wire rope 504 will pull the adjustment roller 502 to slide along the inside of the fixed ring 501. During the sliding process, the elastic member 503 will be compressed. Then the surface of the adjusting roller 502 will contact the surface of the aluminum foil and squeeze the aluminum foil to increase the tension of the aluminum foil. During the contact process, the moving aluminum foil will drive the adjusting roller 502 to rotate, and will not interfere with the movement of the aluminum foil. The adjusting roller 502 cooperates with the guide roller 204 to clean the surface of the aluminum foil. Finally, by driving the driving component 6, the wire rope 504 pulls the adjusting roller 502 as the rotating roller moves, and the tension on the aluminum foil is significantly increased, making the aluminum foil smoother during the winding process, thereby improving the processing quality of the aluminum foil.

[0026] Specifically, it also includes: The limiting component 4 is arranged at the top of the base 1. The limiting component 4 includes two slide rails 401 fixedly connected to the top of the base 1. The surfaces of the two slide rails 401 are slidably connected to the slider 402, and the slider 402 is fixedly connected to the surface of the connecting plate 303.

[0027] By adopting the above technical solution and the design of the limiting component 4, when the connecting plate 303 moves, it will drive the slider 402 to slide on the surface of the slide rail 401, and the moving slider 402 can limit the connecting plate 303, making it move more smoothly.

[0028] Specifically, the drive assembly 6 includes a mounting plate 601 fixedly connected to the top of the base 1, the internal rotation of the mounting plate 601 is connected to a gear 602, a worm 603 is fixedly installed on one side of the gear 602, and a rack 604 meshing with the gear 602 is provided at the top of the base 1, a connecting rod 605 is fixedly installed on one side of the rack 604, and one end of the connecting rod 605 is fixedly connected to the slider 402.

[0029] By adopting the above technical solution and the design of the driving component 6, when the slider 402 moves, it will drive the connecting rod 605 to move, and the connecting rod 605 will drive the rack 604 to move. Because the rack 604 is engaged with the gear 602, the moving rack 604 will drive the gear 602 to rotate, and the gear 602 will drive the worm 603 to rotate. Since the worm 603 is engaged with the worm wheel 505, the worm 603 will drive the worm wheel 505 and the capstan 506 to rotate, thereby winding the wire rope 504 around the surface of the capstan 506.

[0030] Specifically, a guide wheel 7 is provided at the bottom end of the outer surface of the fixing ring 501 , and the steel wire rope 504 is wound around the surface of the guide wheel 7 .

The rotating guide wheel 7 can limit the moving direction of the wire rope 504, ensuring that the wire rope 504 can be smoothly wound around the surface of the winch 506.

[0032] Specifically, the interior of the mounting plate 601 is rotatably connected to a limiting ring 8 located on the surface of the worm 603 , and the limiting ring 8 is fixedly connected to the worm 603 .

[0033] By adopting the above technical solution and the design of the limiting ring 8, when the worm 603 rotates, the limiting ring 8 will be driven to rotate inside the mounting plate 601. Since the surface of the limiting ring 8 fits the inner wall of the mounting plate 601, the rotating limiting ring 8 can limit the gear 602 and the worm 603.

[0034] Specifically, square grooves are respectively formed on the surfaces of the base 1 and the slide rail 401 , and the rack 604 can slide inside the square grooves.

[0036] Specifically, the fixing ring 501 is designed to be arc-shaped, and the adjustment roller 502 located inside the fixing ring 501 is designed to be smooth.

[0037] By adopting the above technical solution, through the design of the fixed ring 501 and the adjusting roller 502, since the fixed ring 501 is designed to be arc-shaped, the adjusting roller 502 will slide around the surface of the guide roller 204, ensuring that the adjusting roller 502 can increase the tension of the aluminum foil, and the adjusting roller 502 located inside the fixed ring 501 is designed to be smooth, thereby ensuring that the adjusting roller 502 can move more smoothly.

During the rotation, the aluminum foil can be wound; S2: During the winding process, the motor 304 can be driven to rotate the screw rod 305, and the threaded plate 306 will descend on the surface of the screw rod 305. The threaded plate 306 will drive the hinge rod 307 to rotate. The rotating hinge rod 307 will pull the connecting plate 303 and the limiting plate 302 to move. The surface of the limiting plate 302 will contact the main winding roller 203, the guide roller 204 and the two ends of the aluminum foil, so that the limiting plate 302 can limit the aluminum foil. S3: When the slider 402 moves, it drives the connecting rod 605 to move, the connecting rod 605 drives the rack 604 to move, the moving rack 604 drives the gear 602 to rotate, the gear 602 drives the worm 603 to rotate, and then the worm 603 drives the worm wheel 505 to rotate; S4: The worm gear 505 drives the capstan 506 to rotate.

S3: When the slider (402) moves, it drives the connecting rod (605) to move, the connecting rod (605) drives the rack (604) to move, the moving rack (604) drives the gear (602) to rotate, the gear (602) drives the worm (603) to rotate, and then the worm (603) drives the worm wheel (505) to rotate; S4: The worm gear (505) drives the capstan (506) to rotate. When the capstan (506) rotates, the steel wire rope (504) is wound around its surface, and the steel wire rope (504) pulls the adjusting roller (502) to slide along the inside of the fixed ring (501). During the sliding process, the elastic member (503) is compressed, and then the surface of the adjusting roller (502) contacts the surface of the aluminum foil and squeezes the aluminum foil, increasing the tension of the aluminum foil and ensuring the uniformity of the winding.
