Description

Technical Field

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

[0002] Battery aluminum foil is the core material of the positive electrode current collector in lithium-ion batteries. It is made from high-purity aluminum and processed into ultra-thin aluminum foil through processes such as casting, cold rolling, annealing, and precision rolling. It has excellent conductivity, good corrosion resistance, high elongation, and uniform thickness tolerance. In the battery, it is mainly used to carry the positive electrode active material, collect and transmit current, and at the same time, it needs to maintain good bonding with the active material to prevent it from falling off during charge and discharge cycles. It can be divided into two categories: digital battery aluminum foil and power battery aluminum foil.

[0003] Slitting devices typically use manual adjustment of the cutter position, requiring operators to disassemble and fix each cutter individually. This process is cumbersome, makes it difficult to quickly adjust the position of multiple cutters, and results in slow adjustment efficiency. Therefore, we propose a stable aluminum foil slitting device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an aluminum foil stable slitting device.

[0005] This utility model is achieved by the following technical solution: an aluminum foil slitting device, including a frame, an unwinding device at the right end of the frame, a winding device at the left end of the frame, an adjusting component at the upper end of the frame, a tensioning component at the middle of the frame, and a first guide roller, a second guide roller, and a third guide roller rotatably connected to the inner wall of the frame. The adjustment assembly includes a mounting bracket, a cylinder is fixedly connected to the top of the mounting bracket, the output end of the cylinder passes through the mounting bracket and is fixedly connected to a fixing plate, a guide groove is provided on the inner wall of the fixing plate, a slide rod is slidably connected to the inner wall of the guide groove, an extension plate is fixedly connected to the left end of the slide rod, a cutter is fixedly connected to the bottom of the extension plate, a slider is fixedly connected to the left end of the extension plate, a guide rail is slidably connected to the inner wall of the slider, and a vertical plate is fixedly connected to the left end of the guide rail.

[0006] With the above technical solution, when it is necessary to adjust the distance between multiple cutters, the cylinder is activated. The output end of the cylinder pushes the fixed plate downward, causing the slide bar to slide along the guide groove. At the same time, the slider slides laterally along the guide rail, driving the extension plate to move, so that the distance between multiple cutters can be adjusted equally. This facilitates flexible adjustment according to the slitting specifications and improves the adjustment efficiency. The unwinding device consists of a support, an unwinding roller, and a motor, and the winding device consists of a support, a winding roller, and a motor.

[0007] As a further improvement to the above solution, the bottom of the mounting bracket is fixedly connected to the top of the frame.

[0008] As a further improvement to the above solution, the top of the upright plate is fixedly connected to the top of the inner wall of the mounting bracket.

[0009] The above technical solution limits the slider by using the guide rail on the right side of the upright plate, so that the slider can only move laterally, and thus the extension plate and the cutter can only move laterally.

[0010] As a further improvement to the above solution, the tensioning assembly includes a bidirectional screw, the surface of which is threadedly connected to two symmetrically arranged mounting seats. A tensioning roller is rotatably connected to the rear end of the mounting seats, and a sliding seat is rotatably connected to the end of the tensioning roller away from the mounting seats. A guide rod is slidably connected to the inner wall of the sliding seat. A bracket is fixedly connected to the top of the frame, and a motor is fixedly connected to the right end of the bracket.

[0011] The above technical solution uses a motor to drive a bidirectional screw to rotate, causing the two mounting seats to move away from each other. This moves the two tension rollers, allowing the sliding seat to slide on the surface of the guide rod. By adjusting the distance between the two tension rollers, tension is applied to the aluminum foil, preventing it from becoming loose or wrinkled during transport and ensuring the slitting quality.

[0012] As a further improvement to the above solution, the surface of the bidirectional screw is rotatably connected to the inner wall of the frame, and both ends of the guide rod are fixedly connected to the inner wall of the frame.

[0013] The above technical solution limits the sliding seat by using a guide rod to prevent deviation during movement, while the sliding seat also supports the tension roller.

[0014] As a further improvement to the above solution, the output end of the motor is fixedly connected to the upper end of the bidirectional screw.

[0015] As a further improvement to the above scheme, the first guide roller is located at the right end of the tension roller, the second guide roller is located at the left end of the tension roller, and the third guide roller is located at the right end of the cutter.

[0016] The above technical solution guides the aluminum foil using the first guide roller, the second guide roller, and the third guide roller, ensuring that the aluminum foil is transported along the path.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features an adjustment component. Specifically, when the distance between multiple cutters needs to be adjusted, a cylinder is activated. The cylinder's output pushes a fixed plate downward, causing a slide bar to slide along a guide groove. Simultaneously, a slider slides laterally along a guide rail, moving an extension plate. This allows for equal-distance adjustment between multiple cutters, facilitating flexible adjustments based on slitting specifications and improving adjustment efficiency.

[0018] This invention utilizes a tensioning assembly. Specifically, by starting a motor, the motor drives a bidirectional screw to rotate, causing two mounting seats to move away from each other. This moves the two tensioning rollers, allowing the sliding seat to slide on the surface of the guide rod. By adjusting the distance between the two tensioning rollers, tension is applied to the aluminum foil, preventing it from becoming loose or wrinkled during transport and ensuring slitting quality.

Adjustment component 4 includes a mounting bracket 401. A cylinder 402 is fixedly connected to the top of the mounting bracket 401. The output end of the cylinder 402 passes through the mounting bracket 401 and is fixedly connected to a fixing plate 403. A guide groove 404 is formed on the inner wall of the fixing plate 403. A slide rod 405 is slidably connected to the inner wall of the guide groove 404. An extension plate 406 is fixedly connected to the left end of the slide rod 405. A cutter 407 is fixedly connected to the bottom of the extension plate 406. A slider 408 is fixedly connected to the left end of the extension plate 406. The inner wall is slidably connected to a guide rail 409, and the left end of the guide rail 409 is fixedly connected to a vertical plate 410. When it is necessary to adjust the distance between multiple cutters 407, the cylinder 402 is activated. The output end of the cylinder 402 pushes the fixed plate 403 downward, causing the slide rod 405 to slide along the guide groove 404. At the same time, the slider 408 slides laterally along the guide rail 409, driving the extension plate 406 to move, so that the distance between multiple cutters 407 can be adjusted equally, which is convenient for flexible adjustment according to the cutting specifications and improves the adjustment efficiency.

[0023] The bottom of the mounting bracket 401 is fixedly connected to the top of the rack 1.

[0024] The top of the upright plate 410 is fixedly connected to the top of the inner wall of the mounting bracket 401.

[0025] The tensioning assembly 5 includes a bidirectional screw 501, with two symmetrically arranged mounting seats 502 threadedly connected to its surface. A tensioning roller 503 is rotatably connected to the rear end of each mounting seat 502. A sliding seat 504 is rotatably connected to the end of the tensioning roller 503 furthest from the mounting seat 502. A guide rod 505 is slidably connected to the inner wall of the sliding seat 504. A bracket 506 is fixedly connected to the top of the frame 1, and a motor 507 is fixedly connected to the right end of the bracket 506. When the motor 507 is started, it drives the bidirectional screw 501 to rotate, causing the two mounting seats 502 to move away from each other. This moves the tensioning roller 503, causing the sliding seat 504 to slide on the surface of the guide rod 505. By adjusting the distance between the two tensioning rollers 503, tension is applied to the aluminum foil, preventing it from becoming loose or wrinkled during transport and ensuring slitting quality.

[0026] The surface of the bidirectional screw 501 is rotatably connected to the inner wall of the frame 1, and the two ends of the guide rod 505 are fixedly connected to the inner wall of the frame 1.

[0027] The output end of motor 507 is fixedly connected to the upper end of bidirectional screw 501.

[0028] The first guide roller 6 is located at the right end of the tension roller 503, the second guide roller 7 is located at the left end of the tension roller 503, and the third guide roller 8 is located at the right end of the cutter 407.

[0029] The implementation principle of the aluminum foil smooth slitting device in this embodiment is as follows: During use, the aluminum foil roll is mounted on the unwinding device 2. Then, the aluminum film is sequentially wound around the first guide roller 6, two tension rollers 503, the second guide roller 7, the third guide roller 8, and the winding device 3 drum, completing the full path laying of the aluminum foil. The unwinding device 2 releases the aluminum foil roll, the cutter 407 slits the aluminum film, and the winding device 3 winds up the slit aluminum foil. When it is necessary to adjust the tension of the aluminum foil, the motor 507 is started. The motor 507 drives the bidirectional screw 501 to rotate, causing the two mounting seats 502 to move away from each other, and the two tension rollers 503... The movement of the 03 slides the sliding seat 504 on the surface of the guide rod 505. By adjusting the distance between the two tension rollers 503, tension is applied to the aluminum foil to prevent it from becoming loose or wrinkled during transport, thus ensuring the slitting quality. When it is necessary to adjust the distance between multiple cutters 407, the cylinder 402 is activated. The output end of the cylinder 402 pushes the fixed plate 403 downward, causing the slide rod 405 to slide along the guide groove 404. At the same time, the slider 408 slides laterally along the guide rail 409, driving the extension plate 406 to move. This allows the multiple cutters 407 to be adjusted at equal distances, facilitating flexible adjustment according to the slitting specifications and improving adjustment efficiency.
