Description

Technical Field

[0001] This invention relates to the field of transmission equipment technology, specifically to a device for peeling, de-powdering, and transmitting aluminum foil with black powder attached to it in battery waste. Background Technology

[0002] In the aluminum foil waste recycling process, the transmission link is a key process connecting waste collection and black powder stripping. Its core function is to accurately and stably transport aluminum foil waste of different specifications (size, thickness) to the stripping equipment (such as crushing rollers), laying the foundation for the efficient separation of aluminum foil and black powder in the subsequent process.

[0003] Existing transmission equipment typically has fixed channel widths and transmission trajectories, making it impossible to flexibly adjust them according to the size of the aluminum foil waste. For small aluminum foil fragments, fixed channels can easily cause the waste to scatter and shift, making it difficult to gather and transmit. For large aluminum foil waste, limited channel space can cause transmission congestion and even damage the waste's shape. When the amount of waste transmitted fluctuates, fixed channels cannot expand or shrink synchronously, resulting in unstable transmission efficiency.

[0004] The lack of a precise guiding mechanism during transmission causes aluminum foil waste to easily deviate from the preset transmission trajectory and fail to be accurately delivered to the corresponding processing area of ​​the stripping equipment (such as directly above the crushing rollers of different sizes). In particular, when aluminum foil waste of different sizes needs to be matched with different stripping stations, the existing guiding structure cannot achieve synchronous reverse adjustment, resulting in misalignment between the waste and the crushing roller, which in turn causes problems such as insufficient stripping and increased aluminum foil loss. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Driven by electric push rods of the No. 1 and No. 2 biasing mechanisms, the conveyor belt angle can be adjusted to switch channels. When a single side conveyor belt is used, half of the channel can be blocked, suitable for the individual transport of small or large aluminum foil waste. When both side conveyor belts are used simultaneously and rotated to a vertical position, the entire channel can be opened to meet the centralized transport needs of large volumes of aluminum foil. It can adapt to different specifications and volumes of waste without changing the conveyor components, greatly improving the equipment's versatility.

[0017] 2. The guiding mechanism, through the linkage of an electric push rod and a bending rod, drives the rack and pinion to mesh and transmit power, forming a suitable guiding channel between the guide bar and the frame assembly. This precisely guides aluminum foil of different specifications to the corresponding crushing roller area. The rotation angle of the frame assembly can be flexibly adjusted to further assist in calibrating the aluminum foil transmission direction and avoid deviation. The limiting sleeve restricts the movement range of the components, ensuring stable meshing of the gear and rack, eliminating the risk of tooth disengagement, providing precise material positioning for subsequent crushing and separation, and ensuring the efficient operation of the separation process.

[0018] 3. Sealing structures such as the sealing strip between the conveyor belt and the deflector plate, and the folded piece between the scraper and the T-groove of the conveyor belt, can effectively seal the gaps between components and prevent the black powder on the surface of the aluminum foil from leaking during the transmission process. At the same time, the scraper can actively scrape off the loose black powder on the surface of the aluminum foil, reducing the amount of dust in subsequent separation processes. This not only ensures a clean workshop environment but also reduces the health risk of operators inhaling dust, meeting the requirements of environmentally friendly production.

[0033] Please see Figures 1 to 12 The present invention provides a technical solution: Example 1, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the first deflection plate 41 of the first deflection mechanism 4 is rotatably mounted on the inner wall of the transmission frame 1 via a pin. The first deflection plate 41 is a metal plate with a wear-resistant coating sprayed on its surface. The first conveyor belt 43 is rotatably mounted inside the first deflection plate 41 via a roller shaft. The first conveyor belt 43 is made of polyurethane and has T-grooves on its surface. The bottom of the inner cavity of the first conveyor belt 43 is connected to a connecting roller 49 via a key. A support shaft seat is welded to the outside of the first deflection plate 41. The first driven plate 45 is rotatably mounted inside the support shaft via a pin shaft. The first extension plate 46 is symmetrically welded to both ends of the first driven plate 45. The outer side of the first extension plate 46 is pressed and adapted to the first conveyor belt 43. A first sealing strip 44, which is made of rubber, is bonded to the inner side of the first deflection mechanism 41. The first sealing strip 44 is located away from the first conveyor belt 43. One side of the deflection plate 41 is bonded to the first extension piece 46 to seal the gap between the first conveyor belt 43 and the first driven plate 45; the bottom of the first driven plate 45 is equipped with the first bearing 47 through the roller body to reduce rotational friction; the first scraper 48 and the second scraper 40 are fixed to the outside of the first conveyor belt 43 by bolts. The scraper 40 is made of rubber. The second scraper 40 slides and adapts to the T-groove opened on the surface of the conveyor belt. The first folding piece 401, which is made of rubber, is bonded to the upper and lower sides of the second scraper 40. The other end of the first folding piece 401 is bonded to the inner wall of the T-groove to achieve sealing and buffering. The length of the first scraper 48 and the second scraper 40 is less than the width of the first conveyor belt 43, so as to provide contact space between the first conveyor belt 43 and the first extension piece 46.

[0034] The second deflection plate 51 of the second deflection mechanism 5 has the same structure as the first deflection plate 41, and is rotatably mounted on the inner wall of the other side of the transmission frame 1 via a pin. The second conveyor belt 52 is rotatably mounted inside via a roller, and has the same structure as the first conveyor belt 43. The bottom of the inner cavity is connected to the connecting shaft 53 via a key. The second bearing 54 is mounted on the outside of the connecting shaft 53. The second sealing strip 55, which is made of rubber, is bonded to the outside of the second bearing 54. The second sealing strip 55 is fixed to the outside of the second deflection plate 51. The second deflection plate 51 has a welded support shaft seat inside, and the second driven plate 56 is rotatably mounted inside via a pin. The two ends of the second driven plate 56 are symmetrically welded with second extension pieces 58. The outside of the second extension pieces 58 is pressed and adapted to the outer wall of the second conveyor belt 52. The bottom of the second sealing strip 55 is bonded with a sealing sheet 57, which is made of rubber. The other end of the sealing sheet 57 is bonded to the outside of the transmission frame 1 to seal the gap between the second deflection plate 51 and the transmission frame 1.

[0035] The first electric push rod 61 of the transmission mechanism 6 is fixed to the outside of the transmission frame 1 by a metal plate. The top of the output end is welded to the first plate 62, and the top of the first plate 62 pushes the first motor 63. The output end of the first motor 63 is fixedly connected to the connecting shaft 53 by a coupling. An arc-shaped groove is opened on the outside of the transmission frame 1. The frame rod welded to the outside of the first motor 63 slides and adapts to the arc-shaped groove. The first limiting sleeve 64 is welded to the outside of the fixed end of the first electric push rod 61 and is set coaxially with the push rod. The outside of the output end of the push rod is squeezed and adapted to the first bending rod 65 by friction protrusion. The first bending piece 66 is welded to the outside of the first bending rod 65, and the other end of the first bending piece 66 is welded to the outside of the transmission frame 1. Electric push rod 67 is fixed to the outer side of the other side of transmission frame 1 by a metal plate. Its structure is the same as that of electric push rod 61. A second plate 68 is welded to the top of the output end. The top of the second plate 68 pushes the second motor 69. Its structure is the same as that of motor 63. The output end of motor 69 is fixedly connected to roller 49 by a coupling. An arc groove is opened on the other side of transmission frame 1. The frame rod of motor 69 slides and adapts to the arc groove. A second limiting sleeve 60 is welded to the outer side of the fixed end of electric push rod 67. The output end is squeezed and adapted to the second bending rod 601 by friction protrusion. A second bending piece 602 is welded to the outer side of bending rod 601. The other end is welded to the outer side of transmission frame 1.

[0036] Start the second electric push rod 67, which pushes the second plate 68 to drive the second motor 69 to slide along the arc-shaped groove, causing the first conveyor belt 43, which is connected to the connecting roller 49, to rotate around the shaft to form a 60° angle with the inner wall of the transmission frame 1, blocking half of the passage of the transmission frame 1. The other end of the connecting roller 49 is connected to the second motor 69 through a coupling. Start the second motor 69, which drives the first conveyor belt 43 to rotate through the connecting roller 49, and puts small aluminum foil waste into the transmission frame 1. The aluminum foil falls onto the first conveyor belt 43. Conveyor belt 43 pulls aluminum foil toward the center of transmission frame 1. At the same time, scraper blade 48 and scraper blade 40 on the outer side of conveyor belt 43 scrape off loose black powder from the surface of aluminum foil. Scraper blade 40 slides along the T-groove to increase the scraping rate of black powder. Folding plate 401 moves and extends with scraper blade 40 to seal the groove and prevent black powder leakage. Sealing strip 44 seals the gap between driven plate 45 and conveyor belt 43 to prevent black powder from entering the deflection plate and affecting the transmission.

[0037] Close the second electric push rod 67 and the second motor 69, reset the first deflection mechanism 4, start the first electric push rod 61, push the first plate 62 to drive the first motor 63 to slide along the arc groove, so that the second conveyor belt 52 connected to the connecting shaft 53 rotates around the pin shaft to form a 60° angle with the inner wall of the transmission frame 1, blocking the other half of the channel; start the first motor 63, drive the second conveyor belt 52 to rotate through the connecting shaft 53; put in large aluminum foil waste, the aluminum foil falls on the second conveyor belt 52, the second conveyor belt 52 drives the aluminum foil downward; the second sealing strip 55 and the sealing plate 57 seal the gap between the second conveyor belt 52 and the second deflection plate 51 to prevent black powder leakage; the second bearing 54 reduces the rotational friction of the connecting shaft 53 to ensure the stable operation of the second conveyor belt 52.

[0038] Simultaneously, the first electric push rod 61 and the second electric push rod 67 are activated to drive the two conveyor belts to rotate to a vertical position, opening all transmission channels; the two conveyor belts are then closed, and the aluminum foil is directly transmitted downward through the transmission frame, improving transmission efficiency and adapting to high-volume processing needs.

[0039] Example 2, as Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the central plate 71 of the guide mechanism 7 is fixed to the center of the transmission frame 1 by bolts; gears 72 are installed inside the central plate 71 through bearings, and the outer sides of gears 72 respectively mesh with rack 73 and rack 76; guide bar 74 is welded to the top of rack 73, and guide bar 74 is welded to the outer side of bending rod 65; frame assembly 75 is welded to the top of guide bar 74, which is composed of a hollow metal frame and a metal rotating plate connected by a pin; guide bar 77 is welded to the top of rack 76, and guide bar 77 is welded to the outer side of bending rod 601; frame assembly 78 is welded to the top of guide bar 77, and its structure is the same as frame assembly 75.

[0040] When the first electric push rod 61 pushes the first motor 63 to slide, the output end of the first electric push rod 61 presses the first bending rod 65 through the friction protrusion, causing the first bending rod 65 to move upward and drive the first guide bar 74 to move upward; the first guide bar 74 drives the first rack 73 to move upward, meshing with the gear 72 and driving the gear 72 to rotate counterclockwise; the gear 72 drives the second rack 76 to move downward, which in turn drives the second guide bar 77 to move downward; the first guide bar 74 and the second frame assembly 78 form a guide channel, precisely guiding the large aluminum foil conveyed by the second conveyor belt 52 directly above the crushing roller in the left half cavity of the peeling frame 2; adjusting the rotation plate angle of the first frame assembly 75 and the second frame assembly 78 further assists in guidance and prevents the aluminum foil from deviating.

[0041] The first limiting sleeve 64 restricts the upward distance of the first bending rod 65, thereby limiting the movement range of the first guide bar 74 and preventing the first rack 73 from disengaging from the gear 72. Similarly, the second limiting sleeve 60 restricts the movement range of the second guide bar 77, ensuring stable meshing and transmission of the guide mechanism 7. In addition, when the first electric push rod 61 retracts, its output end will drive the first bending rod 65 to move downward synchronously until the first bending rod 65 stops at the junction of the fixed end and the output end of the first electric push rod 61.

[0042] Example 3, as Figure 1 and Figure 2 As shown, the peeling frame 2 is made of steel and is welded to the bottom of the transmission frame 1. The servo motor 3 is fixed on both sides by bolts. The output end of the servo motor 3 is fixedly connected to the crushing roller through a coupling. There are 4 crushing rollers in the peeling frame 2, divided into two groups: 2 in the left half cavity and 2 in the right half cavity. The tooth spacing of the crushing roller in the left half cavity is 5mm to adapt to large aluminum foil, and the tooth spacing of the crushing roller in the right half cavity is 2mm to adapt to small aluminum foil. A collection hopper is set below the crushing roller to collect the peeled black powder and broken aluminum foil.

[0043] Small aluminum foils enter the left half of the peeling frame 2 via the guide mechanism 7. The servo motor 3 in the left half of the frame is started, driving the two crushing rollers to rotate in opposite directions at high speed. The teeth of the crushing rollers shear and squeeze the aluminum foil, breaking it into small pieces of 1-2 cm. The black powder on the surface of the aluminum foil is separated from the aluminum foil under the mechanical impact and inertia, and falls to the collection hopper with the airflow. Because of its tough texture, the broken aluminum foil is discharged from the discharge port below as the crushing rollers rotate, thus achieving the initial separation of aluminum foil and black powder.

[0044] Large aluminum foil enters the right half of the peeling frame 2 through the guide mechanism 7. The servo motor 3 of the right half of the frame is started, driving the two crushing rollers to rotate in opposite directions at high speed. The teeth of the crushing rollers break the large aluminum foil into small pieces of 2-3cm. The black powder is released under the impact force and falls into the collection hopper. The broken aluminum foil is discharged from the discharge port, completing the separation.

[0045] During high-volume transfers, both biasing mechanisms are closed, and the aluminum foil directly enters the peeling frame 2. Simultaneously, two sets of crushing rollers are activated to achieve synchronous crushing and peeling of small and large aluminum foils. The crushing and peeling of the aforementioned black powder are both existing methods.

[0046] The working principle of this invention is as follows: The first deflection plate 41 of the first deflection mechanism 4 and the second deflection plate 51 of the second deflection mechanism 5 are symmetrically arranged, selectively blocking half of the space inside the transmission frame 1 to process aluminum foil of different specifications. When smaller aluminum foil needs to be transmitted, the first conveyor belt 43 inside the first deflection plate 41 rotates under the drive of the connecting roller 49, guiding the aluminum foil to gather towards the center of the transmission frame; similarly, when larger aluminum foil needs to be transmitted, the second conveyor belt 52 inside the second deflection plate 51 rotates with the connecting shaft 53, transmitting the aluminum foil downwards. The first deflection mechanism 1 and the second deflection mechanism 5 cannot be started synchronously, but they can be shut down synchronously. When the amount of aluminum foil transmitted is large, the first conveyor belt 43 and the second conveyor belt 52 are reset and kept in a vertical state, thereby expanding the transmission channel.

[0047] The central dividing plate 71 is fixed inside the center of the transmission frame 1, and its internal gear 72 meshes with racks 73 and 76. When the electric push rod 61 pushes the plate 62, it drives the motor 63 to slide along the arc groove on the outside of the transmission frame 1. The output end of the motor 63 drives the shaft 53 to rotate through the coupling, which in turn drives the conveyor belt 52. At the same time, the outer side of the output end of the electric push rod 61 is pressed against the bending rod 65 by friction protrusions. Therefore, the bending rod 65 moves the guide bar 74 upward, and the guide bar 74 moves the rack 73 upward. The guide bar 77 moves in the opposite direction with the rack 76. The two work together to precisely guide the aluminum foil directly above the crushing roller, avoiding aluminum foil deviation and insufficient peeling. The angles of the frame assembly 75 and the frame assembly 78 can be adjusted by rotating the plate to further assist in guidance and adapt to aluminum foil waste of different specifications.

[0048] After the aluminum foil is transferred to the peeling frame 2, the servo motor 3 drives the crushing roller to rotate at high speed. The aluminum foil is peeled off from the black powder through mechanical extrusion and shearing. There are four crushing rollers in the peeling frame 2, which are divided into two groups. One group of two crushing rollers is set in the left half of the peeling frame 2 for crushing larger aluminum foils, while the other group of two crushing rollers is set in the right half of the peeling frame 2 for crushing smaller aluminum foils.

[0049] The teeth of the crushing roller and the impact force generated by the high-speed rotation break the aluminum foil into small pieces. At the same time, the black powder attached to the surface of the aluminum foil separates from the aluminum foil due to inertia. Because the aluminum foil is relatively tough, it still retains its block shape after crushing, while the black powder is separated from the aluminum foil under the action of mechanical vibration and airflow and falls to the collection area at the bottom of the peeling frame 2, completing the initial separation. During the transport of smaller aluminum foil, the second electric push rod 67 pushes the second plate 68, which drives the second motor 69 to slide along the arc-shaped groove on the outside of the transport frame 1. The second motor 69 drives the first conveyor belt 43 to rotate through the connecting roller 49. The first scraper 48 and the second scraper 40 on the outside of the first conveyor belt 43 can scrape off some loose black powder in advance, reducing the peeling pressure of the crushing roller. The height of the first scraper 48 is smaller than the height of the second scraper 40. The second scraper 40 slides along the T-shaped groove on the surface of the first conveyor belt 43 to ensure that the scraper always fits the first conveyor belt 43, improving the pre-peeling and transport effect. At the same time, the first folding piece 401 is not only used for buffering, but also for sealing.

[0050] The first electric push rod 61 pushes the first plate 62, which drives the first motor 63 to slide along the arc groove on the outside of the transmission frame 1. The output end of the first motor 63 drives the connecting shaft 53 to rotate through the coupling, which in turn drives the second conveyor belt 52 to move and deflect upward. The first limit sleeve 64 limits the rising distance of the first bending rod 65, which is the synchronous distance of the first guide bar 74 to rise, so as to prevent the first guide bar 74 from detaching from the central plate 71.

[0051] The first sealing strip 44 seals the gap between the first driven plate 45 and the first conveyor belt 43, and the second sealing strip 55 and the sealing plate 57 seal the gap of the second biasing mechanism to prevent black powder from leaking during transmission, contaminating the equipment or affecting the separation effect; the first bearing 47 and the second bearing 54 reduce the rotational friction of the first driven plate 45 and the connecting shaft 53 respectively, ensuring the long-term stable operation of each component.

[0052] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention.
