[0025] Please refer to Figures 1-4In the embodiment, the driven roller set 3 is clamped by the two vertical plates 2, the aluminum foil used for manufacturing electrolytic capacitor is changed direction by the driven roller set 3, the driving wheel 41 of the inner surface 23 of the two vertical plates 2 driven by the servo motor one 42 rotates, the aluminum foil is pulled to move backward, the servo motor one 42 provides higher precision of the aluminum foil movement precision, the cylinder wheel 51 winds the aluminum foil, the aluminum foil is clamped by the elastic block 53 thrown out, when the servo motor two 56 stops moving, the elastic block 53 is retracted, the cylinder wheel 51 is matched with the wound aluminum foil, and the wound aluminum foil is conveniently taken out. The gap is arranged between the two driving wheels 41, the gap can compress the aluminum foil, the driving wheel set 4 can pull the aluminum foil to the rear. The aluminum foil is clamped by the gap between the two driving wheels 41, so that the aluminum foil can move, the driving wheel 41 and the aluminum foil are made of rubber material, and slipping is avoided. The elastic block 53 comprises a block plate 531, and a triangular block 532 connected to the block plate 531. The side, away from the block plate 531, of the triangular block 532 is a right angle, and the side, away from the triangular block 532, of the block plate 531 is an arc. The triangular block 532 prevents the elastic block 53 from being thrown out of the cylinder wheel 51, and the right angle triangular block 532 facilitates the regular arrangement of the elastic block 53 in the rectangular hole 512 of the cylinder wheel 51. The side, close to the block plate 531, of the triangular block 532 is provided with a silica gel block 54. The reason why the elastic block 53 can be retracted is that the side, close to the block plate 531, of the triangular block 532 is attached with the silica gel block 54, and the block plate 531 is protruded or retracted from the outer surface of the cylinder wheel 51 through the deformation of the silica gel block 54. The side, close to the block plate 531, of the triangular block 532 is provided with a silica gel block 54. The reason why the elastic block 53 can be retracted is that the side, close to the block plate 531, of the triangular block 532 is attached with the silica gel block 54, and the block plate 531 is protruded or retracted from the outer surface of the cylinder wheel 51 through the deformation of the silica gel block 54. The cylinder wheel 51 is provided with four openings 511, the openings 511 are arranged along the axial direction of the cylinder wheel 51, the inside of the cylinder wheel 51 is a rectangular hole 512, and the silica gel block 54 can be attached to the edge of the rectangular hole 512. The four openings 511 correspond to the four elastic blocks 53, so that the elastic blocks 53 are uniformly distributed in the rectangular hole 512.

[0026] Please refer to Figures 2-5In the embodiment, the top of the two vertical plates 2 is provided with a cutter 71 suspended on the inner surface 23. The cutter 71 is fixed on the top of the vertical plate 2 by a cutter seat 72. When the drum wheel 51 is wound to a certain height, the aluminum foil will touch the cutter 71, and the cutting operation of the aluminum foil is completed. The servo motor 2 56 is arranged on the moving plate 55. The bottom of the moving plate 55 is a sliding block 551 which is slidingly connected to a sliding rail 552. The sliding rail 552 is installed on a mounting plate 553. The mounting plate 553 is connected with a cylinder fixed end 61. The moving plate 55 is connected with a cylinder output end 62. The cylinder output end 62 pulls the moving plate 55 to move, and the drum wheel 51 moves. When the drum wheel 51 is pulled out between the two vertical plates 2, the wound aluminum foil will fall down and fall on the discharge plate to be discharged.

[0027] In operation, the aluminum foil is pre-wound on the drum wheel 51 through the driven roller set 3 and the driving wheel set 4. Preferably, other automatic equipment for winding aluminum foil is used. Manual operation is also possible. Then the servo motor 1 42 and the servo motor 2 56 are rapidly rotated to pull the aluminum foil to move backward. The driven roller set 3 changes the direction of the aluminum foil. The driving wheel 41 provides a pulling force for the aluminum foil. The drum wheel 51 of the winding set 5 rotates rapidly under the rotation of the servo motor 2 56. The original silicone block 54 which presses against the telescopic block 53 to prevent the block-shaped plate 531 from extending out of the drum wheel 51 is deformed under the centrifugal force and the extrusion of the telescopic block 53. The block-shaped plate 531 extends out of the outer surface of the drum wheel 51 through the opening 511 and abuts against the center of the aluminum foil wound to form a circle. When the winding height reaches a certain value, the aluminum foil will contact the cutter 71. The cutter 71 cuts the aluminum foil to complete the winding operation. At this time, the servo motor 2 56 and the servo motor 1 42 stop rotating. The silicone block 54 recovers and abuts against the triangular block 532 to push the telescopic block 53 back. The block-shaped plate 531 is retracted into the drum wheel 51. Finally, the cylinder output end 62 pulls the moving plate 55 to make the drum wheel 51 separate from the inner surface 23 formed by the two vertical plates 2. The wound aluminum foil is completely separated and discharged from the discharge plate to enter the subsequent equipment for the next processing.

[0028] Through the above steps, the aluminum foil used for making electrolytic capacitors is changed in direction by the driven roller set 3. The driving wheel 41 of the inner surface 23 of the two vertical plates 2 is rotated by the servo motor 1 42 to pull the aluminum foil to move backward. The servo motor 1 42 provides high precision for the movement of the aluminum foil. The drum wheel 51 winds the aluminum foil and throws it out through the telescopic block 53 to clamp the aluminum foil. When the servo motor 2 56 stops moving, the telescopic block 53 is retracted to make the drum wheel 51 gap fit with the wound aluminum foil for easy removal. The problem that the aluminum foil is wound on the winding rod and is difficult to remove after the winding rod completes the winding of the aluminum foil is solved.
