Description

Technical Field

[0001] This utility model relates to a dust prevention device for casting and rolling in a battery aluminum foil production line, specifically a dust prevention device for casting and rolling in a battery aluminum foil production line, belonging to the technical field of dust prevention devices. Background Technology

[0002] The dust control device for battery aluminum foil production lines is a highly efficient dust removal system specifically designed for the aluminum foil casting and rolling process. Through negative pressure suction, multi-stage filtration (such as cyclone separation + HEPA), and a sealed enclosure structure, it effectively captures aluminum powder, oil mist, and oxide particles generated during the high-temperature rolling process. This device features high-temperature resistance and explosion-proof characteristics, integrates intelligent airflow regulation and automatic dust removal functions, and can reduce PM2.5 concentration in the workshop by more than 90%, significantly reducing surface defects on aluminum foil while meeting environmental emission standards. It is a key piece of equipment for improving the cleanliness and production safety of battery aluminum foil.

[0003] The prior art patent application number is 202221291715.3, entitled "Dustproof Device for Casting and Rolling of Battery Aluminum Foil Production Line," which includes a base, mounting brackets, a first magnetic strip, a dustproof plate, a counterweight mechanism, and a shrink roller mechanism. The mounting brackets are fixedly installed at both ends of the base. The first magnetic strip is fixedly connected to the inner sides of the two mounting brackets. The dustproof plate includes a plastic sheet and a second magnetic strip; the second magnetic strip is fixedly installed on the outer periphery of the plastic sheet; both ends of the dustproof plate are attracted to the two first magnetic strips via the second magnetic strip.

[0004] However, its moving mechanism uses an electric telescopic rod to control the swivel casters for retraction and deployment. This design has significant drawbacks in high-temperature, dusty industrial environments. The motor and transmission components of the electric telescopic rod are constantly exposed to harsh conditions, making them prone to jamming due to dust accumulation or overheating due to high temperatures, affecting stability and increasing maintenance costs and failure risks. Furthermore, the dustproof plate relies solely on the attraction between the second and first magnetic strips for fixation. In the high-frequency vibration environment of the casting and rolling production line, the magnetic attraction structure is prone to loosening or even detachment, leading to dustproof failure. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof device for casting and rolling of battery aluminum foil production line in order to solve the above-mentioned problems. In order to solve the problem that the motor and transmission components of the electric telescopic rod are exposed to harsh working conditions for a long time, which can easily cause jamming due to dust accumulation or overheating due to high temperature, affecting stability and increasing maintenance costs and failure risks. The installation of the dustproof plate relies solely on the adsorption and fixation of the second magnetic strip and the first magnetic strip. In the high-frequency vibration environment of the casting and rolling production line, the magnetic adsorption structure is prone to loosening.

[0006] This utility model is achieved through the following technical solution: a dust prevention device for casting and rolling of battery aluminum foil production line.

[0007] Preferably, the base has an outer frame fixedly connected to its outer side, and an anti-slip pad is adhered to the bottom of the outer frame. Four gear driven screws are rotatably connected to the bottom of the inner cavity of the base. The bottom end of each gear driven screw passes through the base and extends to the inner side of the base, and a threaded sleeve is screwed onto the outer side of each gear driven screw. The anti-slip pad at the bottom of the outer frame can enhance the friction between the base and the ground, preventing the equipment from sliding when fixed.

[0008] Preferably, a mounting plate is fixedly connected between the bottom ends of the threaded sleeve, and four movable wheels are rotatably connected to the bottom of the mounting plate. The mounting plate serves as a support structure for the movable wheels, ensuring that the four movable wheels rise and fall synchronously and avoiding uneven force on one side. The movable wheels adopt a rotating connection method, which facilitates flexible movement of the equipment and reduces the burden of manual handling.

[0009] Preferably, the base has a transmission chamber inside, and two gear transmission rods are rotatably connected to one side of the inner wall of the transmission chamber. One end of the gear transmission rod passes through the transmission chamber and extends into the inner cavity of the base. Two first drive gears are fixedly connected to the outer side of the gear transmission rod. The first drive gears are meshed with the gear driven screw. The meshing design of the gear transmission rod and the first drive gear can realize power transmission, so that the four gear driven screws rotate synchronously, ensuring that the moving wheel rises and falls smoothly and avoiding jamming or deflection.

[0010] Preferably, a rotating rod is rotatably connected to one side of the base. One end of the rotating rod passes through the base and extends into the inner cavity of the transmission chamber. Two second drive gears are fixedly connected to the outer side of the rotating rod. The second drive gears mesh with the gear transmission rod. The entire lifting mechanism can be driven by manually rotating the rotating rod. The operation is simple and requires no electricity, avoiding the risk of failure of the electric telescopic rod in harsh environments and improving reliability.

[0011] Preferably, the top of the base is fixedly connected to two mounting brackets, and a docking compartment is fixedly connected to one side of each mounting bracket. The docking compartments are arranged in sequence, and a first adsorption magnet is fixedly connected to the inner cavity of each docking compartment. An annular groove is formed on the inner side of each docking compartment, and a through groove is formed on one side of each docking compartment. The modular design of the docking compartment facilitates the quick installation and disassembly of the filter plate. The first adsorption magnet provides initial adsorption and fixation, while the annular groove and through groove are used for auxiliary limiting to prevent the filter plate from shaking.

[0012] Preferably, a filter plate is provided on one side of the mounting frame, and the filter plates are arranged in sequence. A fixing plate is fixedly connected to both sides of the filter plate. A limiting cylinder is fixedly connected to one side of the fixing plate. Two limiting grooves are opened on the outer side of the limiting cylinder. The filter plate is accurately positioned by the fixing plate and the limiting cylinder. The limiting groove and the clamping rod can enhance the fixing stability and prevent the filter plate from shifting or falling off in a vibration environment.

[0013] Preferably, a telescopic rod is rotatably connected to the inner side of the fixed plate, and two limiting rods are fixedly connected to the outer side of the telescopic rod. The limiting rods are located inside the limiting groove. One end of the telescopic rod extends into the inner cavity of the docking chamber, and a second adsorption magnet is fixedly connected to one end of the telescopic rod. The second adsorption magnet is adsorbed and connected to the first adsorption magnet. Two locking rods are fixedly connected to the outer side of the telescopic rod. The locking rods are located inside the annular groove. The telescopic rod combines magnetic attraction and mechanical locking for dual fixation. The second adsorption magnet ensures rapid adsorption, and the cooperation between the locking rods and the annular groove provides vibration resistance, allowing the filter plate to be stably installed in a high-frequency vibration environment and avoiding a decrease in dustproof function due to magnetic failure.

[0014] This utility model provides a dust prevention device specifically for casting and rolling in a battery aluminum foil production line, which has the following beneficial effects:

[0015] 1. This dustproof device for casting and rolling of aluminum foil production line for batteries uses a moving mechanism to achieve the lifting and lowering of the moving wheels through the mechanical linkage of gear transmission rod, driven screw and threaded sleeve. Compared with electric telescopic rod, there is no risk of motor overheating or dust jamming, and it is suitable for high temperature and dusty casting and rolling environment.

[0016] 2. This dustproof device for casting and rolling of aluminum foil in battery production line uses a filter plate installation mechanism. Through the adsorption of the first and second adsorption magnets, the filter plates can be easily attached or separated, facilitating daily cleaning or replacement. The vibration-resistant design, with the mechanical cooperation of the limiting rod and limiting groove, and the clamping rod and annular groove, effectively prevents the filter plates from loosening or falling off during high-frequency vibrations in the production line, ensuring long-term sealing.

[0029] This utility model provides a dust prevention device specifically for casting and rolling in a battery aluminum foil production line.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a base 1, an outer frame 101 fixedly connected to the outside of the base 1, an anti-slip pad 102 glued to the bottom of the outer frame 101, and four gear driven screws 2 rotatably connected to the bottom of the inner cavity of the base 1. The bottom end of the gear driven screws 2 passes through the base 1 and extends to the inner side of the base 1, and a threaded sleeve 201 is screwed to the outside of the gear driven screws 2.

[0031] Please refer to it again. Figure 1 ,and Figure 2 A mounting plate 202 is fixedly connected to the bottom end of the threaded sleeve 201. Four moving wheels 203 are rotatably connected to the bottom of the mounting plate 202. A transmission chamber 3 is opened inside the base 1. Two gear transmission rods 301 are rotatably connected to one side of the inner wall of the transmission chamber 3. One end of the gear transmission rod 301 passes through the transmission chamber 3 and extends into the inner cavity of the base 1. Two first drive gears 302 are fixedly connected to the outside of the gear transmission rod 301. The first drive gears 302 are meshed with the gear driven screw 2. A rotating rod 4 is rotatably connected to one side of the base 1. One end of the rotating rod 4 passes through the base 1 and extends into the inner cavity of the transmission chamber 3. Two second drive gears 401 are fixedly connected to the outside of the rotating rod 4. The second drive gears 401 are meshed with the gear transmission rod 301.

[0032] During the power input phase, the operator provides initial power by rotating the rotating rod 4 located on the side of the base 1, which drives the two second drive gears 401 fixedly connected to its outer side to rotate synchronously. During the power transmission phase, the second drive gears 401 mesh with the gear transmission rods 301 in the transmission chamber 3, and the two gear transmission rods 301 transmit power to the gear driven screws 2 through the first drive gears 302 on their outer sides. During the lifting and lowering phase, the four gear driven screws 2 and the threaded sleeve 201 form a threaded pair transmission. When the gear driven screws 2 rotate, the threaded sleeve 201 moves along the screw axis, causing the mounting plate 202 fixedly connected to its bottom end to rise and fall accordingly. During the state transition of the moving wheel 203, when the threaded sleeve 201 rotates... When the device moves downward, the mounting plate 202 drives the four moving wheels 203 to extend out of the base 1 and contact the ground, enabling the device to move flexibly. When the threaded sleeve 201 moves upward, the moving wheels 203 retract into the inner cavity of the base 1, and at the same time, the anti-slip pad 102 at the bottom of the outer frame 101 contacts the ground, making the device enter a stable and fixed state. The mechanism also has a positioning guarantee mechanism, which ensures that the four moving wheels 203 rise and fall synchronously through gear meshing transmission. The self-locking characteristic of the threaded pair transmission is used to maintain the stability of the moving wheels 203 in any position, and the anti-slip pad 102 provides additional friction to prevent the device from sliding when it is fixed. This pure mechanical transmission scheme realizes the smooth and reliable storage and display function of the moving wheels 203, which is particularly suitable for the high temperature and dusty environment of the casting and rolling production line.

[0033] Please refer to it again. Figure 1 , Figure 3 and Figure 4 Two mounting brackets 5 are fixedly connected to the top of the base 1. A docking chamber 501 is fixedly connected to one side of each mounting bracket 5, and the docking chambers 501 are arranged sequentially. A first adsorption magnet 502 is fixedly connected to the inner cavity of each docking chamber 501. An annular groove 503 is formed on the inner side of each docking chamber 501, and a through groove 504 is formed on one side of each docking chamber 501. A filter plate 6 is arranged on one side of each mounting bracket 5, and the filter plates 6 are arranged sequentially. Fixing plates 601 are fixedly connected to both sides of each filter plate 6. A limiting cylinder 602 is fixedly connected to one side of each fixing plate 601. The limiting cylinder 602... Two limiting grooves 603 are provided on the outer side. A telescopic rod 7 is rotatably connected to the inner side of the fixing plate 601. Two limiting rods 701 are fixedly connected to the outer side of the telescopic rod 7. The limiting rods 701 are located inside the limiting grooves 603. One end of the telescopic rod 7 extends into the inner cavity of the docking chamber 501. A second adsorption magnet 702 is fixedly connected to one end of the telescopic rod 7. The second adsorption magnet 702 is adsorbed and connected to the first adsorption magnet 502. Two locking rods 703 are fixedly connected to the outer side of the telescopic rod 7. The locking rods 703 are located inside the annular groove 503.

[0034] Align the fixing plates 601 on both sides of the filter plate 6 with the docking chamber 501 on the mounting frame 5, and push the filter plate 6 so that one end of the telescopic rod 7 is inserted into the inner cavity of the docking chamber 501. At this time, the locking rod 703 on the outside of the telescopic rod 7 aligns with the annular groove 503 on the inside of the docking chamber 501. Simultaneously, the second adsorption magnet 702 at the end of the telescopic rod 7 approaches the first adsorption magnet 502 inside the docking chamber 501. When the second adsorption magnet 702 and the first adsorption magnet 502 are adsorbed and connected, the magnetic force between them firmly fixes the telescopic rod 7, making the filter plate 6 and the docking chamber 501 fit tightly together. During the adsorption process, the locking rod 703 slides along the annular groove 503 and gets stuck in it, forming a mechanical limit, further preventing the filter plate 6 from moving in the horizontal direction. Meanwhile, the limiting rod 701 slides in the limiting groove 603, restricting the rotation of the telescopic rod 7 relative to the fixed plate 601, ensuring a stable connection between the telescopic rod 7 and the docking chamber 501, and completing the rapid installation of the filter plate 6. When it is necessary to disassemble the filter plate 6 for cleaning or replacement, pull the telescopic rod 7 to overcome the adsorption force between the first adsorption magnet 502 and the second adsorption magnet 702, so that the second adsorption magnet 702 separates from the first adsorption magnet 502. Meanwhile, the limiting rod 701 slides in the limiting groove 603, and the locking rod 703 slides in the annular groove 503 and moves away from the limiting of the annular groove 503 to the position of the through groove 504. When the telescopic rod 7 is pulled out to a certain position, the filter plate 6 can be pulled out from the docking chamber 501 as a whole, completing the quick disassembly of the filter plate 6, which is convenient for subsequent cleaning or replacement of the filter plate 6.

[0035] Working principle: In the power input stage, the operator provides initial power by rotating the rotating rod 4 located on the side of the base 1, which drives the two second drive gears 401 fixedly connected to its outer side to rotate synchronously; in the power transmission stage, the second drive gears 401 mesh with the gear transmission rods 301 in the transmission chamber 3, and the two gear transmission rods 301 transmit power to the gear driven screws 2 through the first drive gears 302 on their outer sides; in the lifting execution stage, the four gear driven screws 2 and the threaded sleeve 201 form a threaded pair transmission. When the gear driven screws 2 rotate, the threaded sleeve 201 moves along the screw axis, causing the mounting plate 202 fixedly connected to its bottom end to rise and fall accordingly; during the state transition of the moving wheel 203, when the threaded... When the sleeve 201 moves downward, the mounting plate 202 drives the four moving wheels 203 to extend out of the base 1 and contact the ground, enabling the device to move flexibly. When the threaded sleeve 201 moves upward, the moving wheels 203 retract into the inner cavity of the base 1, and at the same time, the anti-slip pad 102 at the bottom of the outer frame 101 contacts the ground, making the device enter a stable and fixed state. The mechanism is also equipped with a positioning guarantee mechanism, which ensures that the four moving wheels 203 rise and fall synchronously through gear meshing transmission. The self-locking characteristic of the threaded pair transmission is used to maintain the stability of the moving wheels 203 in any position, and the anti-slip pad 102 provides additional friction when the device is fixed to prevent it from sliding. This pure mechanical transmission scheme realizes the smooth and reliable storage and display function of the moving wheels 203, which is particularly suitable for the high temperature and dusty environment of the casting and rolling production line.

[0036] Align the fixing plates 601 on both sides of the filter plate 6 with the docking chamber 501 on the mounting bracket 5, and push the filter plate 6 so that one end of the telescopic rod 7 is inserted into the inner cavity of the docking chamber 501. At this time, the locking rod 703 on the outside of the telescopic rod 7 is aligned with the annular groove 503 on the inside of the docking chamber 501. At the same time, the second adsorption magnet 702 at the end of the telescopic rod 7 approaches the first adsorption magnet 502 inside the docking chamber 501. When the second adsorption magnet 702 and the first adsorption magnet 502 are adsorbed and connected, the magnetic force between the two will firmly fix the telescopic rod 7, so that the filter plate 6 and the docking chamber 501 are tightly fitted. During the adsorption process, the locking rod 703 slides along the annular groove 503 and is locked in it, forming a mechanical limit, further preventing the filter plate 6 from moving in the horizontal direction; while the limiting rod 701 is in the limiting groove 603. The telescopic rod 7 slides, restricting its rotation relative to the fixed plate 601, ensuring a stable connection between the telescopic rod 7 and the docking chamber 501, and completing the quick installation of the filter plate 6. When it is necessary to disassemble the filter plate 6 for cleaning or replacement, the telescopic rod 7 is pulled to overcome the attraction force between the first adsorption magnet 502 and the second adsorption magnet 702, causing the second adsorption magnet 702 to separate from the first adsorption magnet 502. At the same time, the limiting rod 701 slides in the limiting groove 603, and the locking rod 703 slides in the annular groove 503 and moves away from the limiting position of the annular groove 503 to the position of the through groove 504. When the telescopic rod 7 is pulled out to a certain position, the filter plate 6 can be pulled out from the docking chamber 501 as a whole, completing the quick disassembly of the filter plate 6, which facilitates subsequent cleaning or replacement operations of the filter plate 6.
