Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic capacitor production technology, and in particular to an aluminum foil slitting device for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum foil is a key material in aluminum electrolytic capacitors and can be divided into anode aluminum foil and cathode aluminum foil. As the anode, after current is passed through the electrolyte, a very thin oxide film forms on its surface. This oxide film has rectifying characteristics and can act as a dielectric, which is one of the key factors determining the performance of the capacitor. As the cathode, it is mainly used to form the capacitor structure together with the anode aluminum foil and the electrolyte, playing a role in conduction and support.

[0003] Chinese Patent No. CN221659378U discloses a cutting device for processing aluminum foil for electrolytic capacitors, including a support frame assembly, a limiting assembly, a flattening assembly, a cutting assembly, a pressing assembly, and a slitting assembly. Compared with traditional aluminum foil cutting devices, this slitting device conveys the aluminum foil to be cut, restricts the conveying direction of the aluminum foil during the conveying process to prevent the aluminum foil from deviating, and uses pressure to flatten the curvature and wrinkles of the aluminum foil during the cutting process, which facilitates automated cutting and makes the aluminum foil cutting effect better.

[0004] However, the above technical solution has the following shortcomings: the slitting blade of the device is fixed on the slitting shaft, so when slitting aluminum foil, the width of the aluminum foil is fixed and the interval of the slitting blade cannot be adjusted according to the needs, which reduces the applicability of the device. Utility Model Content

The cutting device includes a motor mounted on the upright blocks, a rotating shaft and a support cylinder rotatably connected to the upright blocks, multiple mounting rings linearly distributed on the rotating shaft, cutting blades mounted on the mounting rings, and an adjustment assembly mounted on the mounting rings. The motor and support cylinder are driven together. The adjustment assembly includes a guide block mounted on the mounting rings, a fixing bolt threaded through and connected to the mounting rings, a push plate mounted on the mounting rings, and a clamping block between the guide block and the push plate. The fixing bolt and the clamping block are threaded together.

[0007] Preferably, the base is provided with a first conveyor seat and a second conveyor seat, and the upright block is disposed between the first conveyor seat and the second conveyor seat.

[0008] Preferably, the slitting device further includes a first gear and a second gear coaxially mounted on the rotating shaft and the support cylinder, respectively, and the first gear and the second gear are meshed together.

[0009] Preferably, a protective cover is provided on the upright block.

[0010] Preferably, the rotating shaft is provided with four elongated holes and grooves arranged in a ring array, the guide block is slidably disposed inside the groove, and the clamping block is located inside the groove.

[0011] Preferably, the two ends of the clamping block abut against the guide block and the push plate, respectively.

[0012] Preferably, the first conveyor seat is provided with a support frame, and the support frame is provided with vertically distributed cylinders, mounting seats that are driven and connected to the cylinders, and pressure rollers that are rotatably connected to the mounting seats.

[0013] Preferably, the mounting base is provided with two symmetrically distributed fixing blocks, and the support frame is provided with guide grooves for the fixing blocks to slide vertically.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This invention, through its adjustable components, can adjust the spacing between adjacent slitting blades according to the slitting size requirements of aluminum foil, enabling the slitting device to adapt to different processing needs and providing a stable fixing effect on the slitting blades. This not only expands the applicability of the device but also makes it simple and convenient to operate, demonstrating excellent practicality. Attached Figure Description

[0021] Example 1

[0022] like Figures 1-4 As shown in the figure, the aluminum foil slitting device for aluminum electrolytic capacitors proposed in this embodiment includes a base 1 and a slitting device; two symmetrically distributed upright blocks 4 are arranged on the base 1, and a first conveying seat 2 and a second conveying seat 3 are arranged on the base 1, with the upright blocks 4 arranged between the first conveying seat 2 and the second conveying seat 3.

[0023] The slitting device includes a motor 5 mounted on a vertical block 4, a rotating shaft 6 and a support cylinder 7 rotatably connected to the vertical block 4, multiple mounting rings 10 linearly distributed on the rotating shaft 6, slitting blades 11 mounted on the mounting rings 10, and an adjustment assembly mounted on the mounting rings 10. The motor 5 and the support cylinder 7 are driven together. The adjustment assembly includes a guide block 14 mounted on the mounting rings 10, a fixing bolt 15 that passes through and is threaded onto the mounting rings 10, a push plate 17 mounted on the mounting rings 10, and a clamping block 16 between the guide block 14 and the push plate 17. The fixing bolt 15 and the clamping block 16 are threaded together.

[0024] like Figure 1 and Figure 2 As shown, the slitting device also includes a first gear 8 and a second gear 9 coaxially mounted on the rotating shaft 6 and the support cylinder 7, respectively. The first gear 8 and the second gear 9 are meshed together. A protective cover 18 is provided on the upright block 4. The protective cover 18 is used to isolate and protect the first gear 8 and the second gear 9.

[0025] like Figure 3 As shown, the rotating shaft 6 is provided with four elongated holes 12 arranged in a ring array and a sliding groove 13. The guide block 14 is slidably disposed inside the sliding groove 13, and the clamping block 16 is located inside the sliding groove 13. The two ends of the clamping block 16 abut against the guide block 14 and the push plate 17 respectively.

[0026] In this embodiment, aluminum foil is conveyed by the first conveyor seat 2 and the second conveyor seat 3. When the aluminum foil is conveyed to the position of the slitting device, the motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the first gear 8 and the slitting blade 11 to rotate. Then, the first gear 8 and the second gear 9 mesh and drive each other, so that the second gear 9 drives the support cylinder 7 to rotate. The support cylinder 7 conveys the aluminum foil while cooperating with multiple slitting blades 11 to slit the aluminum foil. When it is necessary to adjust the spacing between adjacent slitting blades 11 to meet the requirements of slitting aluminum foil of different sizes, the fixing bolt 15 can be screwed out of the mounting ring 10 first, and then the slitting blade 11 can be moved to the determined position. At this time, the push plate 17 and the guide block 14 will push the clamping block 16 to slide in the slide groove 13. Then, the fixing bolt 15 can be screwed back into the mounting ring 10 and threaded through the clamping block 16 until the mounting ring 10 and the clamping block 16 are pressed tightly on both sides of the elongated hole 12, thus completing the position adjustment operation of the slitting blade 11. This not only expands the applicability of the device, but also makes the operation simple and convenient, and has good practicality.

[0027] Example 2

[0028] like Figure 1 and Figure 4 As shown, the aluminum foil cutting device for aluminum electrolytic capacitors proposed in this embodiment has the following features compared to Embodiment 1: In this embodiment, a support frame 19 is provided on the first conveying seat 2, and a vertically distributed cylinder 20, a mounting seat 21 driven and connected to the cylinder 20, and a pressure roller 22 rotatably connected to the mounting seat 21 are provided on the support frame 19. Two symmetrically distributed fixing blocks 23 are provided on the mounting seat 21, and a guide groove for the fixing blocks 23 to slide vertically is provided on the support frame 19.

[0029] In this embodiment, before the aluminum foil is slit, the first conveyor seat 2 conveys the aluminum foil through the support frame 19, and then the aluminum foil is flattened by the pressure roller 22 to improve the slit quality. At the same time, the cylinder 20 is used to control the squeezing force between the pressure roller 22 and the aluminum foil, and the fixing block 23 is used to ensure the stability of the cylinder 20 driving the mounting seat 21, thereby ensuring the balance of both sides of the pressure roller 22.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
