[0028] Among them: it also includes a connecting block 7 and a pressing roller 8.

The shearing roller can be quickly disassembled and replaced, which improves production efficiency. It can also automatically feed the material. While feeding, it can also ensure that the aluminum foil will not warp or wrinkle, thereby improving the quality of the finished product.

[0029] The working principle of a foil cutting device based on ultra-high voltage etching foil for aluminum electrolytic capacitors provided by the present invention is as follows: when performing the foil cutting work, the operator first grasps the handle and gently lifts the pressure roller 8 upward so that the outer surface of the pressure roller 8 leaves the outer surface of the rear roller 52, and then puts the flattened etching foil on the rear roller 52, and then puts down the pressure roller 8. The pressure roller 8 presses the etching foil tightly against the outer surface of the rear roller 52 by its own weight. The single-chip computer 9 controls the operation of the motor 56. The output end of the motor 56 drives the pulley 1 53 located on the right side of the front roller 51 to rotate. Because the right sides of the front roller 51 and the rear roller 52 are both provided with a pulley 1 53, and the two pulleys 1 53 are connected by a belt transmission, the rear roller 52 also rotates accordingly, and the rotating rear roller 52 sends the etching foil forward by friction. , realizing automatic feeding and keeping the corrosion foil flat. At the same time, the output end of the motor 56 drives the front roller 51 at the same time. Because the pulley 2 55 is fixedly connected to the right side of the right ring sleeve 4, the pulley 2 55 and the pulley 1 53 located on the right side of the front roller 51 are connected by the belt 2 transmission, so the shear roller 54 also rotates. When the corrosion foil contacts the front roller 51, the rotating front roller continues to feed the corrosion foil forward. Because the outer surface of the shear roller 54 is provided with evenly distributed cutting knives, the outer edge of the cutting knife is installed in conjunction with the outer surface of the front roller 51, the corrosion foil will be cut into aluminum foil strips of the same width by the cutting knife. When it is necessary to cut aluminum foil strips of different specifications, it is necessary to replace the shear rollers 54 of different specifications. The operator grabs the handle 68 and pulls it upwards. The limit column 66 slides upward, and spring 2 67 is compressed by force until the limit column 66 moves to the inside of the limit hole 69. At this time, the quick-release block 64 loses its restriction, and spring 1 63 expands without force. Spring 1 63 slides the slide column 62 to the left, and the quick-release block 64 also moves to the left at the same time until spring 1 63 reaches its elastic limit. The circular column of the slide column 62 is located inside the square hole of the slide hole 61, and the left ring sleeve at the lower end of the quick-release block 64 also leaves the left side of the shear roller 54 at the same time. Because the circular hole and the square hole of the slide hole 61 have the same diameter, the circular column and the square column of the slide column 62 also have the same diameter. Therefore, when the circular column of the slide column 62 is located inside the square hole of the slide hole 61, the circular column is not restricted by the square hole and can deflect back and forth to prevent the shear roller 54 from being blocked. When the work is changed, the shearing roller 54 is quickly removed without restriction, and then the right end of the shearing roller 54 of appropriate specifications is inserted into the inside of the right ring sleeve 4, so that the shearing roller 54 remains straight, and the quick-release block 64 is toggled to align the left ring sleeve at the lower end of the quick-release block 64 with the left end of the shearing roller 54. The handle 68 is grasped and pulled upward, and the limiting column 66 slides upward, and the spring 2 67 is compressed by force, pushing the quick-release block 64 to the right, and the sliding column 62 also moves to the right. The spring 1 63 is compressed by force until the sliding column 62 is completely returned to its original position, and the left end of the shearing roller 54 is plugged into the inner wall of the left ring sleeve, and the lower end of the limiting column 66 is aligned with the limiting hole 69. The handle 68 is released, and the spring 2 67 rebounds without force, driving the limiting column 66 to move downward so that the lower end of the limiting column 66 is located inside the limiting hole 69.The quick-release block 64 is fixed, and the replacement work is now complete. The shear roller can be quickly disassembled and replaced, which improves production efficiency. It can also automatically feed the material while ensuring that the aluminum foil will not warp or wrinkle, thereby improving the quality of the finished product.
