Description

Technical Field

[0001] The utility model relates to the field of capacitor production and processing, in particular to aluminum foil cutting equipment for chip-type aluminum electrolytic capacitors. Background Art

[0002] Aluminum electrolytic capacitors are capacitors made of an aluminum cylinder as the negative electrode, filled with liquid electrolyte, and a curved aluminum strip inserted as the positive electrode. While aluminum electrolytic capacitors have been steadily growing in the traditional consumer electronics field, their application areas have been expanded to many emerging fields such as energy-saving lamps, inverters, and new energy with structural transformation and technological progress. The aluminum foil of aluminum electrolytic capacitors needs to be cut using a cutting device during processing.

[0003] According to Chinese patent publication number CN220784034U, a device for cutting aluminum foil for aluminum electrolytic capacitors is disclosed. This utility model uses a bidirectional screw in conjunction with a second transverse plate to drive two knife holders to move toward each other, causing the knife holders to drive the cutting knives to move and adjust the distance between the two cutting knives. This allows the cutting length of the aluminum foil of the aluminum electrolytic capacitor to be adjusted, thereby expanding the application range of the cutting device.

[0004] In response to the above-mentioned disclosed patent content, two electric push rods and a pressure plate are provided so that when cutting the aluminum foil, the two electric push rods are first started to move the pressure plate down and press the aluminum foil, thereby facilitating the cutting of the aluminum foil. However, since this pressing method requires the electric push rod to be operated all the time, it will increase energy consumption and increase the cost of using the equipment. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide an aluminum foil cutting device for chip-type aluminum electrolytic capacitors to solve the technical problem that the energy consumption of the device will increase by setting two electric push rods and a pressure plate to compress the aluminum foil.

[0009] By adopting the above technical solution, when the pressing plate moves downward and contacts the aluminum foil, as the lifting plate continues to move downward, the pressing plate can tightly press the aluminum foil, thereby preventing the aluminum foil from deflecting during the cutting process.

[0010] Furthermore, a movable rod is provided on one side of the locking plate and extends to the outside of the knife holder, and a pull rod is installed at one end of the movable rod.

[0011] By adopting the above technical solution, when disassembling the cutting knife, the staff can pull the movable rod through the pull rod, and the movable rod drives the locking plate to move, thereby moving the locking plate out from the locking groove.

[0012] Furthermore, two hydraulic cylinders are installed on the top of the frame, and the output ends of the hydraulic cylinders are installed with lifting plates through piston rods.

[0013] By adopting the above technical solution, when the aluminum foil needs to be cut, the hydraulic cylinder can be started, and the operation of the hydraulic cylinder causes the piston rod to extend or contract, thereby driving the lifting plate to move, and then driving the cutting knife to move.

[0018] Furthermore, a mounting plate is installed on one side of the frame, and an aluminum foil roller is rotatably provided on the mounting plate.

[0019] By adopting the above technical solution, the staff can pull the aluminum electrolytic capacitor aluminum foil on the aluminum foil roll, so that the aluminum foil passes through the material port on the left and is spread onto the workbench.

[0020] Furthermore, the movable seat is threadedly connected to the bidirectional screw rod, one end of the bidirectional screw rod is connected to the inner wall of the groove through a bearing, and the outer wall of the movable seat is fitted with the inner wall of the groove.

[0021] By adopting the above technical solution, the two movable seats can be driven to move when the bidirectional screw rod rotates, and the movable seat drives the knife seat to move, and then drives the cutting knife to move.

[0022] Furthermore, both sides of the top of the inserting plate and one side of the locking plate are arranged in an inclined manner, and the locking plate is located inside the locking groove.

[0023] By adopting the above technical solution, when the locking plate is inserted into the locking groove, the plug-in plate can be locked to prevent the plug-in plate from falling off at will.

[0024] Furthermore, a rubber pad is installed at the bottom of the pressing plate, and the bottom height of the pressing plate is lower than the bottom height of the cutting knife.

[0025] By adopting the above technical solution, the pressing plate can first press the aluminum foil, which is convenient for subsequent cutting of the aluminum foil by the cutting knife.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The utility model is provided with a pressing assembly. When the lifting plate moves downward, it drives the pressing plate to move downward, so that the pressing plate first contacts the aluminum foil. As the lifting plate continues to move downward, it squeezes the return spring, causing the return spring to be compressed. At the same time, the pressing plate is tightly pressed against the aluminum foil by the reaction force of the return spring, thereby improving the stability of the aluminum foil and preventing it from deflecting during the cutting process and affecting the cutting efficiency. In addition, in this way, the pressing plate can press the aluminum foil without adding two electric drive mechanisms, thereby saving energy consumption and reducing the cost of equipment use.

[0028] When the cutting blade is fully inserted into the slot, the locking plate will be aligned with the locking slot, and the spring will stretch and push the locking plate to reset and move, so that the locking plate moves into the locking slot and thus limits and fixes the cutting blade. In this way, the cutting blade can be quickly disassembled and assembled, and the operation process is simple and convenient, without the need to use multiple bolts to fix the cutting blade, thereby simplifying the operation steps and improving the efficiency of disassembling and replacing the cutting blade.
