Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic capacitor production, and in particular relates to a solid capacitor aluminum foil cutting mechanism. Background Art

[0002] The production process of aluminum electrolytic capacitors includes: cutting, winding (binding), impregnation, assembly (assembly), cleaning, casing, aging, testing, inspection, packaging, etc. Cutting of aluminum foil: Before producing a certain type of electrolytic capacitor, the aluminum foil will be cut into different widths according to its size; and aluminum foil is mostly transported in the form of coils, and cutting equipment is required for cutting when it is used. Traditional cutting equipment mostly uses punching to cut aluminum foil, and when cutting aluminum foil, it is impossible to locate the cutting distance of the roll aluminum foil, which leads to non-uniform size when cutting aluminum foil in the later stage, and when the punching tool is worn, the punching tool needs to be replaced. Replacing the tool not only affects the cutting of the aluminum foil, but also after the tool is replaced, the tool cannot be accurately aligned with the initial position, which easily leads to deviation in the later cutting of the aluminum foil.

[0003] To this end, a cutting line for the production and processing of aluminum electrolytic capacitors with publication number "CN116525318A" and a method of using the same include: a workbench, a U-shaped frame fixedly connected to the top of the workbench, a cylinder fixedly passing through the U-shaped frame, a sliding plate fixedly connected to the output shaft of the cylinder slidably connected to the U-shaped frame, a cutting knife for cutting fixedly connected to the bottom of the sliding plate, and the cutting distance of the aluminum foil roll can be adjusted by rotating the screw rod. The lifting and lowering of the sliding plate can not only be used for cutting operations, but also control the limiting position of the aluminum foil roll by the rotating baffle to ensure the cutting accuracy. When the cutting knife is worn, the electric push rod pushes the circular ring sleeve to move to complete the grinding of the cutting knife. There is no need to replace the cutting knife, thereby ensuring that the cutting size is the same before and after grinding.

[0004] However, for the above-mentioned aluminum electrolytic capacitor production and processing cutting line and its use method, although the roll of aluminum foil is inserted into the placement table, the output shaft of the cylinder drives the sliding plate and the cutting knife to move downward, the sliding plate drives the first connecting plate to move downward through the L-shaped rod, the first connecting plate drives the sliding rod to move downward, the sliding rod drives the rotating ring to rotate through the second connecting rod, and then the rotating ring drives the first connecting rod to rotate, which can make the clamping plate move toward the middle to complete the clamping of the roll of aluminum foil. However, there are still the following obvious defects during use: when the roll of aluminum foil is clamped by the clamping plate and cut by the cutting knife, since there will be a hollow cavity inside the rolled roll of aluminum foil after winding, a large downward thrust will be generated when the cutting knife moves downward, causing the cut roll of aluminum foil to be flattened and deformed.
