Description

Technical Field

[0001] This utility model relates to the field of aluminum foil slitting technology, specifically a slitting machine for aluminum foil of new energy vehicle batteries. Background Technology

[0002] In the current booming development of the new energy vehicle industry, battery aluminum foil plays a crucial role as a key material. As the current collector in the positive electrode of the battery, it bears the heavy responsibility of collecting and conducting current, directly affecting the charging and discharging efficiency of the battery. At the same time, it is also often used in battery casing, which is of great significance for ensuring the stability of the battery's internal structure and improving battery safety and lifespan.

[0003] In the production process of battery aluminum foil, the slitting process is crucial, requiring the precise cutting of large rolls of aluminum foil into suitable specifications. During slitting, as the aluminum foil roll diameter gradually decreases, the tension decreases, leading to poor stability and a high risk of misalignment. Simultaneously, the heat generated by the high-frequency friction between the cutting tool and the aluminum foil alters the tool's metal structure, reducing its hardness and accelerating sharpness loss. This decline in tool performance results in uneven stress on the aluminum foil, further exacerbating the misalignment problem. When misalignment occurs, manual adjustment is typically required after machine shutdown, leading to reduced production efficiency and product quality. To reduce aluminum foil misalignment during slitting and ensure both production efficiency and product quality, we propose a slitting machine for aluminum foil used in new energy vehicle batteries.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 This utility model provides a technical solution: a slitting machine for aluminum foil of new energy vehicle batteries, including a mounting platform 1, a feeding roller 2 rotatably mounted on the mounting platform 1, an aluminum foil roll disposed outside the feeding roller 2, a number of sets of conveying rollers 13 and receiving rollers 8 rotatably mounted on the mounting platform 1, a limiting component for limiting the position of aluminum foil mounted on the mounting platform 1, and a slitting component for slitting aluminum foil mounted on the mounting platform 1.

[0031] The limiting assembly includes several sets of front limiting rollers 11, which are rotatably mounted on the mounting platform 1. Several sets of limiting rings 25 are movably sleeved on the outside of the front limiting rollers 11. A connecting plate 26 is fixedly connected to the bottom of the limiting ring 25. A movable plate 27 is fixedly connected between two adjacent sets of connecting plates 26. The movable plate 27 is slidably mounted on the mounting platform 1. A connecting frame 28 is fixedly mounted on the left connecting plate 26. A sliding cover 20 is fixedly connected to the connecting frame 28. A sliding plate 32 is slidably connected to the inner wall of the sliding cover 20. A spacing adjustment mechanism for adjusting the distance between two sets of movable plates 27 is installed on the mounting platform 1. A tension adjustment mechanism for ensuring constant aluminum foil tension is installed on the mounting platform 1. An anti-deviation mechanism for preventing the aluminum foil from shifting after slitting is installed on the mounting platform 1.

[0032] In use, the distance between the two sets of moving plates 27 is adjusted by the spacing adjustment mechanism so that the side of the sliding plate 32 closest to the aluminum foil roll abuts against the aluminum foil roll. At this time, the distance between the two sets of limiting rings 25 is the width of the aluminum foil. Driven by external power, the feeding roller 2, conveying roller 13, and take-up roller 8 rotate. The aluminum foil passes through the front limiting roller 11, passes through the conveying roller 13, and enters the slitting assembly. During this process, the limiting rings 25 limit the aluminum foil to prevent it from shifting. After the slitting assembly completes the slitting of the aluminum foil, the anti-shifting mechanism prevents the slitting aluminum foil from shifting, ensuring that the take-up roller 8 can smoothly rewind it. Throughout the slitting process, the tension of the aluminum foil remains constant under the action of the tension adjustment mechanism, so that the aluminum foil can be transported stably, reducing the possibility of shifting, thereby reducing downtime caused by aluminum foil shifting, and ensuring production efficiency and product quality.

[0033] The spacing adjustment mechanism includes a motor 17, which is fixedly mounted on the mounting platform 1. The output end of the motor 17 is fixedly connected to a drive wheel 18. A bidirectional screw 16 is rotatably mounted on the mounting platform 1. The bidirectional screw 16 is threaded through a moving plate 27. A driven wheel 15 is fixedly sleeved on the outside of the bidirectional screw 16. A belt is tensioned between the driven wheel 15 and the drive wheel 18.

[0034] The starter motor 17 drives the drive wheel 18 to rotate, which in turn drives the bidirectional screw 16 to rotate via the driven wheel 15, thus adjusting the distance between the two sets of moving plates 27.

[0035] The anti-deviation mechanism includes several sets of rear limit rollers 7, which are rotatably mounted on the mounting platform 1. Several sets of limit cylinders 14 are slidably sleeved on the outer side of the rear limit rollers 7, and positioning screws 3 are threaded on the limit cylinders 14.

[0036] According to the width of the cut aluminum foil, manually adjust each set of limiting cylinders 14 to the appropriate position. After adjustment, tighten the positioning screws 3 to fix the position of the limiting cylinders 14. The limiting cylinders 14 restrict the position of the aluminum foil and prevent it from shifting.

[0037] The tension adjustment mechanism includes a cylinder 4, which is fixedly mounted on the mounting platform 1. The output end of the cylinder 4 is fixedly connected to a mounting bracket 23. A tension roller 24 is rotatably mounted on the mounting bracket 23. A lower mounting plate 35 is fixedly connected to the sliding cover 20. A sliding cylinder 21 is fixedly connected to the top of the lower mounting plate 35. A connecting cylinder 30 is slidably connected to the inner wall of the sliding cylinder 21. An upper mounting block 31 is fixedly connected to the sliding plate 32. The top of the connecting cylinder 30 is fixedly connected to the bottom of the upper mounting block 31. A sliding block 34 is slidably connected to the inner wall of the sliding cylinder 21. A spring 33 is fixedly connected to the top of the sliding block 34. The top of the spring 33 is fixedly connected to the bottom of the upper mounting block 31. A pressure sensor 36 is fixedly mounted on the top of the lower mounting plate 35.

[0038] Initially, under the action of spring 33, the upper mounting block 31 abuts against the bottom of the aluminum foil roll. At this time, spring 33 is in a compressed state, and a certain pressure is applied to pressure sensor 36 through sliding block 34. As the aluminum foil is continuously cut, the diameter of the aluminum foil roll on the feeding roller 2 gradually decreases, the aluminum foil tension gradually decreases, and at the same time, the upper mounting block 31 gradually rises. This reduces the deformation of spring 33, thereby reducing the pressure on pressure sensor 36. The control center controls cylinder 4 to drive tension roller 24 to descend based on the signal changes of pressure sensor 36, in order to increase the tension of aluminum foil and thus maintain constant tension.

[0039] The cutting assembly includes a mounting cylinder 5, which is fixedly mounted on a mounting platform 1. Several sets of mounting covers 37 are slidably sleeved on the outside of the mounting cylinder 5. A blade 40 is fixedly connected to the bottom of the mounting cover 37. A positioning mechanism that can fix the position of the mounting cover 37 is installed on the mounting cover 37. A cooling mechanism that reduces the temperature of the blade 40 is installed on the mounting platform 1. A collection mechanism that collects aluminum powder generated during cutting is installed on the mounting platform 1.

[0040] According to the slitting requirements, the movable mounting cover 37 is moved to a suitable position and fixed by the positioning mechanism, thereby fixing the position of the blade 40. As the aluminum foil passes through the blade 40, it is cut. A cooling mechanism removes the large amount of heat generated by long-term friction on the blade 40, reducing its temperature, slowing down blade performance loss, and minimizing aluminum foil misalignment caused by blade wear. Aluminum powder generated during the slitting process is collected by a collection mechanism, ensuring a clean production environment and protecting the health of employees.

[0041] The positioning mechanism includes several sets of rotating bolts 39, which are rotatably mounted on the mounting cover 37. The external threads of the rotating bolts 39 are fitted with limit blocks 38, which are slidably connected to the inner wall of the mounting cylinder 5. The mounting cylinder 5 has a movable opening that matches the rotating bolts 39, and the rotating bolts 39 are movably connected to the movable opening.

[0042] Rotating the rotating bolt 39 moves the limiting block 38, causing the limiting block 38 to press against the inner wall of the mounting cylinder 5, thus fixing the position of the mounting cover 37.

[0043] The cooling mechanism includes an air pump 29, which is fixedly installed on the mounting platform 1. The exhaust port of the air pump 29 is fixedly connected to an exhaust pipe 9. An air supply hood 10 is fixedly connected to the mounting platform 1. The end of the exhaust pipe 9 away from the air pump 29 is fixedly connected to the air supply hood 10. Several sets of conveying hoods 6 are fixedly connected to the air supply hood 10. The side of the conveying hood 6 near the blade 40 is fixedly connected to a wind guide hood 12.

[0044] The air discharged by the air pump 29 passes through the exhaust pipe 9, the air supply hood 10, the conveying hood 6 and the air guide hood 12 in sequence, and blows onto the blade 40, thereby reducing the temperature of the blade 40.

[0045] The collection mechanism includes a collection box 19, which is fixedly connected to the mounting platform 1 and located below the mounting cylinder 5. The air pump 29's suction port is fixedly connected to the collection box 19.

[0046] The air pump 29 generates suction at the top opening of the collection box 19, drawing aluminum powder into the collection box 19.

[0047] The top of the mounting bracket 23 is fixedly connected to several sets of telescopic rods 22, and the top of the telescopic rods 22 is fixedly connected to the mounting platform 1.

[0048] Both the exhaust port and the intake port of the air pump 29 are equipped with filters.

[0049] Working principle: In the initial state, under the action of spring 33, the mounting block 31 abuts against the bottom of the aluminum foil roll. At this time, spring 33 is in a compressed state, and a certain pressure is applied to pressure sensor 36 through sliding block 34. Start motor 17 drives drive wheel 18 to rotate, which drives double screw 16 to rotate through driven wheel 15. This adjusts the distance between the two sets of moving plates 27, so that the side of sliding plate 32 closest to aluminum foil roll abuts against the aluminum foil roll. At this time, the distance between the two sets of limiting rings 25 is the width of aluminum foil. According to the cutting requirements, move mounting cover 37 to a suitable position, rotate rotating bolt 39 to drive limiting block 38 to move, so that limiting block 38 abuts against the inner wall of mounting cylinder 5, thereby fixing mounting cover 37 and fixing the position of blade 40. Driven by external power, the feeding roller 2, conveying roller 13, and take-up roller 8 rotate. The aluminum foil passes through the front limit roller 11 and the conveying roller 13. During this process, the limit ring 25 limits the aluminum foil to prevent it from shifting. When the aluminum foil passes through the blade 40, it is cut by the blade 40. During cutting, the air discharged by the air pump 29 passes through the exhaust pipe 9, the air supply hood 10, the conveying hood 6, and the air guide hood 12 in sequence, and blows onto the blade 40, thereby reducing the temperature of the blade 40, slowing down the loss of blade performance, and reducing the aluminum foil shift caused by blade wear. The aluminum powder generated during cutting is sucked into the collection box 19. According to the width of the cut aluminum foil, each set of limit cylinders 14 is manually adjusted to a suitable position. After adjustment, the positioning screws 3 are tightened to fix the position of the limit cylinders 14. The position of the aluminum foil is restricted by the limit cylinders 14 to prevent it from shifting, ensuring that the take-up roller 8 can smoothly rewind it. As the aluminum foil is continuously cut, the diameter of the aluminum foil roll on the feeding roller 2 gradually decreases, and the aluminum foil tension gradually decreases. At the same time, the upper mounting block 31 gradually rises, which reduces the deformation of the spring 33, thereby reducing the pressure on the pressure sensor 36. Based on the signal changes of the pressure sensor 36, the control center controls the cylinder 4 to drive the tension roller 24 to descend, thereby increasing the tension of the aluminum foil and maintaining constant tension. This ensures stable aluminum foil conveying, reduces the possibility of deviation, and reduces downtime caused by aluminum foil deviation, thus ensuring production efficiency and product quality.
