Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic capacitors, in particular to an electrolytic capacitor nailing and rolling machine. Background Art

[0002] An aluminum electrolytic capacitor is a capacitor made of an aluminum cylinder as a negative electrode, a liquid electrolyte is filled inside, and a bent aluminum strip is inserted as a positive electrode. It is called an aluminum electrolytic capacitor. It is a general-purpose electrolytic capacitor made of aluminum material with good electrical properties, a wide range of applications and high reliability. During the production of aluminum electrolytic capacitors, a nailing and rolling machine is required to wrap the capacitor with aluminum foil; for example, a Chinese patent with an existing authorization announcement number of CN219892054U discloses a nailing and rolling device for an electrolytic capacitor, including a base and a capacitor film assembly, wherein the top surface of the base is fixedly connected to a plurality of support blocks, the top surfaces of the plurality of support blocks are fixedly connected to a support seat, the top surface of the base is fixedly connected to a motor, one end of a connecting rod is fixedly connected to the motor shaft, the other end of the connecting rod is fixedly connected to a rotating table, and a rotating rod is rotatably connected inside the rotating table. The utility model is provided with a rotating rod, a limiting block one, a forward screw rod, a connecting block one, a reverse screw rod, a connecting rod, a limiting block two, etc., and the rotating rod can be rotated to simultaneously drive the forward screw rod and the reverse screw rod to rotate, and drive the sliders on both sides to move simultaneously, so that the moving distances can be equal, and it is convenient to fix the pins of the electrolytic containers with different spacings, thereby improving practicality. By providing a limiting block three, a threaded rod structure, a threaded sleeve, etc., the inserted pins can be effectively fixed, the fixation of the pins can be improved, and the stability of the pins when moving can be improved.

[0003] However, in actual application, the above-mentioned nailing and rolling machine still has the following problems: although the above-mentioned nailing and rolling machine can plug in the pins of aluminum electrolytic capacitors of different models, during the process of starting the motor to drive the rotating table to rotate and wind, since the capacitor film component is not clamped and limited, the capacitor film component is easily offset or skewed after being affected by the centrifugal force during the rotation process, which may cause the capacitor film component to be not in the center position when rolling the film, resulting in uneven force during film rolling, affecting the film rolling effect, and thus reducing the production quality of the capacitor; in addition, after each film rolling is completed, the above-mentioned nailing and rolling machine needs to manually cut the aluminum foil, which is not convenient to operate and reduces the nailing and rolling efficiency of the nailing and rolling machine.

[0008] Furthermore, the intersection of the cross-shaped support frame is arranged at the axis center of the circular groove.
