Description

Technical Field

[0001] This application relates to the technical field of battery production and processing, and in particular to a device for collecting die-cutting waste materials used in battery production. Background Technology

[0002] In the production of new energy batteries, aluminum foil is needed for wrapping. During the cutting process of aluminum foil, waste and dust are generated. In the context of pursuing environmental protection and resource recycling, the waste and dust are collected.

[0003] Typically, a settling tank for receiving waste is connected to a die-cutting device. A conveying channel is connected below the settling tank, and a collection box is connected to the end of the conveying channel away from the settling tank. All the waste is eventually collected in the collection box.

[0004] Aluminum foil waste is quite fluffy, which makes the collection boxes easy to fill up. There are usually pressure plates inside the collection boxes to press the aluminum foil waste in order to collect more waste, but multiple collection boxes are still needed to collect the waste alternately. Summary of the Invention

[0005] To accommodate the collection of large amounts of waste, this application provides a die-cutting waste collection device for battery production.

[0006] This application provides a waste collection device for die-cutting materials in battery production, which adopts the following technical solution: A device for collecting die-cutting waste from battery production, comprising: The collection box is equipped with a first helical rod; A pre-compression chamber is connected to the collection box. A second spiral rod is coaxially and fixedly connected to the first spiral rod. The second spiral rod is located inside the pre-compression chamber. The outer diameter of the second spiral rod is smaller than the outer diameter of the first spiral rod. An exhaust box is installed above the pre-compression box. The exhaust box has multiple first vents and second vents. The first vents are connected to the collection box, and the second vents are connected to the pre-compression box. A compression chamber, which is connected to a pre-compression chamber, is equipped with a sealing plate inside the compression chamber, and a driving component that causes the sealing plate to block or open the connection between the pre-compression chamber and the compression chamber; The extrusion plate is connected to one end of the sealing plate along its length. The receiving box is equipped with an opening and closing door. The receiving box and the compression box are connected by opening and closing the door. The opening and closing door and the extrusion plate are arranged in parallel, and a gap is formed between the opening and closing door and the extrusion plate to compress waste. The part of the receiving box near the opening and closing door is provided with an exhaust hole.

[0007] By adopting the above technical solution, during use, the driving component drives the sealing plate to block the connection between the pre-pressing box and the compression box, so that the pre-pressing box and the compression box are temporarily not connected. The aluminum foil waste generated by die-cutting first enters the pre-pressing box. Since the first screw and the second screw are coaxially fixed, the rotation of the first screw synchronously drives the rotation of the second screw. The first screw conveys the aluminum foil waste into the pre-pressing box, and the second screw continues to squeeze the aluminum foil waste, which will perform preliminary pre-compression of the waste. During the pre-compression process, the rotation of the first screw and the second screw generates air. The air carried by the waste will enter the exhaust box through the second vent of the exhaust box, and then flow into the collection box through the first vent, realizing the air discharge, further reducing the fluffiness of the waste and increasing the amount of waste squeezed. Once the pre-compression chamber is filled with compressed waste, the sealing plate is moved, connecting the pre-compression chamber to the compression chamber. After the waste enters the compression chamber, the extrusion plate connected to the sealing plate moves towards the opening and closing door. The gap between the extrusion plate and the opening and closing door is used to perform a secondary high-pressure compression of the waste to form aluminum ingots. Air is discharged from the exhaust port. The opening and closing door is opened, and the sealing plate continues to move, allowing the compressed waste aluminum ingots to enter the receiving box. This significantly reduces the volume of aluminum foil waste, increases the loading capacity of the receiving box, reduces the frequency of alternating material receiving in the collection box, and improves collection efficiency.

[0008] Optionally, a graphite slider is connected to the side of the sealing plate away from the pre-compression box, and multiple graphite sliders are distributed at intervals.

[0009] By adopting the above technical solution, when the driving component drives the sealing plate to move, the graphite slider on the side of the sealing plate away from the pre-compression box contacts and slides relative to the inner wall of the compression box; the lubrication characteristics of the graphite slider itself can effectively reduce the sliding friction, reduce the resistance when the sealing plate moves, make the sealing and releasing action of the sealing plate smoother, and improve the stability of the device operation.

[0010] Optionally, a connecting plate is connected to the end of the sealing plate away from the extrusion plate, and a connecting block is connected to the piston rod of the driving member. The connecting plate has a slot, the piston rod extends into the slot, and the slot provides space for the connecting block to move along with the piston rod.

[0011] By adopting the above technical solution, when the driving component moves, the piston rod drives the connecting block to move. The reserved movement space in the slot allows the connecting block to move adaptively within the slot when the sealing plate shifts laterally due to friction or positioning deviation during movement, thus avoiding the transmission of lateral force to the piston rod. At the same time, this clearance fit can compensate for the installation error between the piston rod and the sealing plate, ensuring that the sealing plate can accurately seal the connection between the pre-pressurization box and the compression box, reducing the probability of failure and improving the reliability of the device operation.

[0012] Optionally, the connecting block is embedded with a spring, and one end of the spring is in contact with the connecting plate.

[0013] By adopting the above technical solution, the buffering effect of the spring can absorb the impact load when the sealing plate is used for sealing, reduce the impact force on the connecting block, connecting plate, piston rod and driving components, reduce the wear and damage risk of each component, and further improve the stability and service life of the device.

[0014] Optionally, a sealing ball is installed inside the exhaust box to block the second vent. The second vent has a variable diameter structure, with the larger outer diameter end located inside the exhaust box. The sealing ball extends into the pre-compression box through the second vent. The sealing ball has a vent hole. A guide rod is installed inside the exhaust box. The guide rod is inserted into the vent hole, and a gap is left between the guide rod and the inner wall of the vent hole.

[0015] By adopting the above technical solution, since the second vent has a variable diameter structure, the end with the larger outer diameter is located inside the exhaust box, and the sealing ball extends into the pre-compression box, it can prevent the waste material in the pre-compression box from entering the exhaust box. When the waste material in the pre-compression box is pre-compressed by the second screw rod, the internal air is compressed and pressure is generated, pushing the sealing ball away from the second vent. The sealing ball and the second vent have a small gap, which can allow exhaust. At the same time, the vent hole on the sealing ball cooperates with the guide rod, which can guide the movement of the sealing ball, so that the vent hole can also have an exhaust effect. When the pre-compression is completed, the pressure in the pre-compression box decreases, and the sealing ball falls back under its own weight or air pressure, re-sealing the second vent. The distance between the guide rod and the inner wall of the vent hole can ensure that air can pass through the vent smoothly without affecting the exhaust effect. At the same time, it effectively prevents the waste material from blocking the second vent, ensuring the stability and continuity of the pre-compression exhaust process, and further improving the waste material compression effect.

[0016] Optionally, it also includes a lifting assembly for driving the guide rod up and down. One end of the guide rod inserted into the vent is connected to a limiting block, and the sealing ball is connected to a stop that cooperates with the limiting block, so that one end of the guide rod is always located inside the sealing ball. When the guide rod moves up, the sealing ball leaves the second vent.

[0017] By adopting the above technical solution, when the pre-pressure box is being pre-pressurized and vented, the lifting component remains stationary. After the pre-pressurization is completed, the lifting component drives the guide rod to move upward. The guide rod drives the sealing ball to move upward through the vent, so that the sealing ball leaves the second vent. If there is debris in the exhaust box, it can be discharged through the second vent.

[0018] Optionally, a linkage plate is also included, on which all the guide rods are mounted, and the lifting assembly controls the lifting of the linkage plate.

[0019] By adopting the above technical solution, when the lifting component is activated, it drives the linkage plate to rise and fall as a whole. Since all guide rods are installed on the linkage plate, the linkage plate will drive all guide rods to move up and down synchronously, thereby driving all blocking balls to open or close synchronously.

[0020] Optionally, the linkage plate includes a first rotating plate and a second rotating plate, which are rotatably connected by a rotating shaft. The lifting assembly includes a lifting rod and a cylinder that drives the lifting rod to move up and down. The cylinder is located outside the exhaust box. The lifting rod extends into the exhaust box and connects to the first rotating plate. The guide rods are evenly distributed on the first rotating plate and the second rotating plate. Two support blocks and a support spring for supporting the support blocks are installed inside the exhaust box. The support spring drives the support blocks to always have an upward tendency. When the first rotating plate and the second rotating plate are in contact with the support blocks, the first rotating plate and the second rotating plate unfold into a planar state and continue to descend with the lifting rod, causing the sealing ball to block the second vent. When the lifting rod rises, the first rotating plate and the second rotating plate rotate relative to each other and move closer.

[0021] By adopting the above technical solution, when the second vent needs to be opened, the cylinder drives the lifting rod to rise, which in turn drives the first rotating plate to rise. The first and second rotating plates rotate relative to each other via a rotating shaft and approach (fold). Debris on the upper surface of the linkage plate falls into the bottom of the exhaust box and drives the guide rod to move upward synchronously, thus opening the second exhaust port. The debris in the exhaust box can be basically discharged. The support block is driven by the support spring and slides upward. When it needs to be blocked, the cylinder drives the lifting rod to fall, and the linkage plate falls under the action of gravity and the pressure of the lifting rod. After the first and second rotating plates contact the support block respectively, they continue to move downward, so that the first and second rotating plates gradually unfold into a planar state. At this time, the blocking ball has not yet blocked the second vent. Only when the support spring is pressed downward further will the blocking ball block the second vent. The setting of the support spring and the support block allows the blocking ball to maintain a vertical downward state to block the second vent.

[0022] Optionally, it also includes a stacking area and a pallet placed on the stacking area. The stacking area is equipped with a cylinder, and the piston rod of the cylinder is connected to a push plate. The push plate slides into the receiving box and pushes the waste material into the pallet.

[0023] By adopting the above technical solution, when the compressed waste material in the receiving box accumulates to a certain amount, the cylinder drives the piston rod to extend, which drives the push plate to slide into the receiving box. The push plate pushes the compressed waste material in the receiving box onto the pallet. The pallet is placed in the stacking area to facilitate the centralized stacking and subsequent transfer of waste material. This automatic transfer structure does not require manual intervention, improves the automation level of waste material collection, and reduces the labor intensity of operators.

[0024] Optionally, a brush is mounted on the push plate.

[0025] By adopting the above technical solution, when the cylinder drives the push plate to move inside the receiving box, the brush on the push plate contacts and slides relative to the inner wall of the receiving box. The brush can sweep off the waste debris attached to the inner wall of the receiving box and push it onto the pallet along with the push plate. This can realize the simultaneous pushing of waste and cleaning of the inner wall, avoid the residue of waste debris, ensure the effective volume of the receiving box, reduce the need for frequent cleaning of the receiving box due to residue, and reduce maintenance costs.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. Collect aluminum foil waste to achieve environmental protection and resource recycling. Through pre-compression and secondary compression, the fluffiness of aluminum foil waste is effectively reduced, the waste volume is significantly reduced, and the loading capacity of the collection box is increased. 2. After extrusion, aluminum ingots are formed and transferred to pallets for convenient transportation and improved efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 14 This application will be described in further detail.

[0030] Example 1: Example 1 of this application discloses a die-cutting waste collection device for battery production.

[0031] Reference Figure 1 and Figure 2 A waste collection device for battery manufacturing includes a collection box 10, which comprises an upper cavity 11 for receiving waste and a lower cavity 12 for conveying waste. A first spiral rod 20 is installed inside the lower cavity 12, and the first spiral rod 20 conveys the waste in a spiral direction. A pre-compression box 40 is connected to one side wall of the collection box 10. The pre-compression box 40 is completely connected to the lower cavity 12, and a second spiral rod 30 is fixedly connected to one end of the first spiral rod 20 facing into the pre-compression box 40. The second spiral rod 30 is entirely located inside the pre-compression box 40, and its outer diameter is smaller than that of the first spiral rod 20. This allows the first spiral rod 20 to rotate synchronously with the second spiral rod 30, achieving a smooth conveying of waste from the collection box 10 to the pre-compression box 40. At the same time, the smaller outer diameter of the second spiral rod 30 creates a smaller pushing space, initially achieving pre-compression of the waste.

[0032] Reference Figure 3 The first screw is provided with two screws, and the two first screws 20 share the same drive motor. The drive motor drives the two first screws 20 to rotate synchronously through gear transmission.

[0033] Reference Figure 2 and Figure 4 An exhaust box 50 is installed above the pre-compression box 40. The bottom of the exhaust box 50 is fixedly connected to the top of the pre-compression box 40, and the side wall of the exhaust box 50 is fixedly connected to the side wall of the collection box 10. A first vent 51 is opened on the side wall of the exhaust box 50, which communicates with the collection box 10. A second vent 52 is opened at the bottom of the exhaust box 50, which communicates with the pre-compression box 40, forming an air circulation channel between the pre-compression box 40 and the collection box 10. The first screw rod 20 and the second screw rod 30 also carry a small amount of air during rotation. Driven by the screw rotation and air volume, the waste material smoothly enters the pre-compression box 40, and the gas in the waste material can be discharged through the second exhaust port 612, increasing the compression amount of the aluminum foil waste.

[0034] Reference Figure 3 A compression box 60 is fixedly installed on the side of the pre-compression box 40 away from the collection box 10, and is connected to the interior of the pre-compression box 40. A sealing plate 61 is installed inside the compression box 60 to seal the connection between the two. The sealing plate 61 is vertically positioned and slides against the inner wall of the compression box 60. A driving component 63, preferably a cylinder, is installed on the outer side of the compression box 60 to drive the sealing plate 61 to move horizontally. Multiple graphite sliders 611 are fixedly connected at intervals on the side of the sealing plate 61 facing away from the pre-compression box 40. A connecting frame connects adjacent graphite sliders 611. The graphite sliders 611 slide in contact with the inner wall of the compression box 60, and the lubrication and wear resistance of the graphite sliders 611 reduces the frictional resistance of the sealing plate 61 during movement.

[0035] Reference Figure 3 and Figure 5 One end of the compression box 60 is connected to a receiving box 70, which is equipped with an openable and closable door 71. The opening and closing of the door 71 is also achieved by a cylinder. Multiple exhaust holes 612 are provided on the top of the compression box 60 near the door 71, and the exhaust holes 612 are connected to the outside through a gas collection hood 613. One end of the sealing plate 61 along its length is connected to an extrusion plate 62, and the other end is connected to a connecting plate 64. The extrusion plate 62 and the door 71 are arranged parallel to each other, forming a gap between the door 71 and the extrusion plate 62 for extruding waste material, thus extruding the waste material from aluminum foil into aluminum ingots. After extrusion, the door 71 opens, and the extrusion plate 62 pushes the aluminum ingots into the receiving box 70.

[0036] Reference Figure 6 The piston rod end of the cylinder that drives the sealing plate 61 to move is connected to a connecting block 65. The connecting plate 64 has a slot 66 on the side facing the connecting block 65 that is compatible with the connecting block 65. The piston rod drives the connecting block 65 to be inserted into the slot 66. The slot 66 is only for the piston rod to move. The connecting block 65 is always located in the slot 66. The internal space of the slot 66 is larger than the volume of the connecting block 65, leaving room for the connecting block 65 to move with the piston rod, so as to realize the flexible connection between the driving component 63 and the sealing plate 61.

[0037] Reference Figure 7 Meanwhile, a spring 67 is embedded in the side of the connecting block 65 facing the connecting plate 64. One end of the spring 67 is in close contact with the inner wall of the slot 66 of the connecting plate 64 to form a buffer structure.

[0038] Reference Figure 8 and Figure 9 To achieve automatic transfer of compressed waste, the device also includes a stacking area 80 and a pallet 81. The stacking area 80 is located near the receiving box 70 and the collection box 10, allowing for efficient use of the overall space. The pallet 81 is placed within the stacking area 80 for forklift transport. A horizontally positioned cylinder is mounted on the support frame of the stacking area 80, located above the pallet 81. A push plate 83 is fixedly connected to the piston rod end of the cylinder. The size of the push plate 83 is adapted to the internal cross-section of the receiving box 70, allowing it to slide into the receiving box 70 under the drive of the cylinder. After multiple aluminum ingots are arranged side by side in the receiving box 70, the push plate 83 can push the entire row of aluminum ingots onto the pallet 81.

[0039] There is a gap between the push plate 83, the bottom of the receiving box 70, and the pallet 81. A brush 84 is installed on the side of the push plate 83 away from the stacking area 80, and the brush 84 contacts the bottom of the box. During the movement of the push plate 83, the brush 84 simultaneously cleans the waste debris on the inner wall of the receiving box 70.

[0040] Reference Figure 5 and Figure 9 A protective cover 82 is installed in the material pushing area, and the pallet 81 is located inside the protective cover 82. The protective cover 82 is fixedly connected to the intelligent control box. A protective door 821 is set on the side of the protective cover 82 closest to the intelligent control box. When the protective door 821 is open, the forklift can transport the pallet 81 normally. When the protective door 821 is closed, the pallet 81 is protected by the protective cover 82. During the process of the pusher plate 83 pushing the aluminum ingot, it is completely isolated from the outside world, improving the personal safety of on-site construction personnel.

[0041] The implementation principle of the die-cutting waste collection device for battery production in Embodiment 1 of this application is as follows: In the initial state, the drive unit 63 drives the sealing plate 61 to block the connection between the pre-compression box 40 and the compression box 60, and the opening and closing door 71 is in the closed state. The aluminum foil waste generated by die-cutting first enters the collection box 10, which drives the first screw rod 20 to rotate. The first screw rod 20 simultaneously drives the second screw rod 30 to rotate, pushing the waste from the collection box 10 into the pre-compression box 40. The smaller outer diameter of the second screw rod 30 is used to perform preliminary pre-compression of the waste. The air squeezed out of the waste enters the exhaust box 5 through the second vent 52. The waste material flows into the collection box 10 through the first vent 51, allowing air to escape and reducing its bulkiness. Then, the drive unit 63 moves the sealing plate 61 away from the connection point, opening the connection between the pre-compression box 40 and the compression box 60. The pre-compressed waste material enters the compression box 60. After entering the compression box 60, the drive unit 63 again moves the sealing plate 61 in the opposite direction, causing the extrusion plate 62 to move towards the opening / closing door 71. The gap between the extrusion plate 62 and the opening / closing door 71 is used to perform a second, powerful compression of the waste material. After compression, the opening / closing door 71 is opened, and the waste material, compressed into aluminum ingots, is pushed into the collection box 70. The cylinder in the stacking area 80 drives the push plate 83 to move, pushing the compressed waste material onto the pallet 81 in the stacking area 80. The push plate 83 resets, the opening / closing door 71 closes, and the sealing plate 61 re-seals the connection between the pre-compression box 40 and the compression box 60, entering the next collection and compression cycle.

[0042] Example 2: The difference between Example 2 and Example 1 is that, in order to avoid the waste material entering the exhaust box 50 with the air during the pre-compression process and causing the vent to be blocked, the structure inside the exhaust box 50 is further refined, while the other structures and principles are the same.

[0043] Reference Figure 10 and Figure 11 Inside the exhaust box 50, a sealing ball 90 is installed at each position corresponding to the second vent 52 to block the second vent 52.

[0044] Reference Figure 12 In Embodiment 2, the second vent 52 adopts a variable diameter structure. The end with the larger outer diameter is located inside the exhaust box 50, while the end with the smaller outer diameter communicates with the pre-pressure box 40. Part of the sealing ball 90 extends into the pre-pressure box 40 through the second vent 52. A through vent 91 is provided at the center of the sealing ball 90. A guide rod 53 is vertically installed inside the exhaust box 50 corresponding to the position of each sealing ball 90. The lower end of the guide rod 53 is inserted into the vent 91, and a gap is left between the outer wall of the guide rod 53 and the inner wall of the vent 91. The guide rod 53 restricts the rotation of the sealing ball 90, keeping the vent 91 connected to the pre-pressure box 40 and the exhaust box 50, ensuring smooth air passage.

[0045] Reference Figure 12 and Figure 13One end of the guide rod 53 inserted into the vent hole 91 is fixedly connected to a limiting block 54. The inner wall of the vent hole 91 of the sealing ball 90 is fixedly connected to a stop 92 that cooperates with the limiting block 54. The stop 92 is a protrusion, and the protrusions are distributed circumferentially along the vent hole 91. There is a gap between the protrusion and the vertical guide rod 53. Through the abutting cooperation between the limiting block 54 and the stop 92, it is ensured that one end of the guide rod 53 is always inside the sealing ball 90, and the sealing ball 90 is prevented from detaching from the guide rod 53.

[0046] Reference Figure 11 and Figure 12 The rotation of the first spiral rod 20 and the second spiral rod 30 carries a certain amount of air, causing the waste material to enter the pre-compression chamber 40. The waste material itself also tends to be pushed forward by the airflow. The waste material and the airflow it carries exert a squeezing and pushing effect on the sealing ball 90, causing it to rotate slightly around its own center, thus buffering the waste material. However, because the sealing ball 90 is restricted by the guide rod 53, the vent 91 of the sealing ball 90 is always connected to the pre-compression chamber 40 and the exhaust chamber 50. The sealing ball 90 also tends to move upwards under the pressure of the waste material, creating a gap between the sealing ball 90 and the inner wall of the second vent 52, which also forms an exhaust channel.

[0047] Reference Figure 11 The device also includes a lifting assembly 100 for driving the guide rods 53 to move up and down. A linkage plate 200 is installed inside the exhaust box 50. The upper ends of all guide rods 53 are connected and fixedly installed on a linkage plate 200, and the synchronous lifting of all guide rods 53 is achieved through the linkage plate 200.

[0048] Reference Figure 11 and Figure 14 The linkage plate 200 is composed of a first rotating plate 210 and a second rotating plate 220. The first rotating plate 210 and the second rotating plate 220 are rotatably connected by a rotating shaft. The lifting assembly 100 includes a lifting rod 110 and a cylinder that drives the lifting rod 110 to move up and down. The cylinder is located outside the exhaust box 50, and its cylinder body is fixedly connected to the top of the exhaust box 50 through a bracket. The lower end of the lifting rod 110 passes through the top plate of the exhaust box 50, extends into the interior of the exhaust box 50, and is fixedly connected to the first rotating plate 210. The guide rods 53 are evenly distributed on the first rotating plate 210 and the second rotating plate 220.

[0049] Reference Figure 11 and Figure 12Inside the exhaust box 50, two support blocks 300 are installed below the first rotating plate 210 and the second rotating plate 220. Each support block 300 is fixedly connected to a support spring 310 at its bottom. The lower end of the support spring 310 is fixedly connected to the bottom of the exhaust box 50. The support spring 310 is always in a compressed state, causing the support block 300 to always have an upward tendency. When the first rotating plate 210 and the second rotating plate 220 contact the corresponding support block 300, they unfold into a horizontal plane under the support of the support block 300. At this time, if the lifting rod 110 continues to descend, it can push the support block 300 to compress the support spring 310, so that the sealing ball 90 tightly seals the second vent 52.

[0050] During the pre-compression process, the lifting assembly 100 is activated, driving the guide rod 53 to move upward, which in turn moves the sealing ball 90 upward. A gap exists between the sealing ball 90 and the inner wall of the second vent 52. The air squeezed out of the waste material enters the exhaust box 50 through the gap between the sealing ball 90 and the second vent 52, as well as the vent 91, and then flows into the collection box 10 through the first vent 51, thus venting the air. At this time, the first rotating plate 210 and the second rotating plate 220, driven by the lifting rod 110, keep the entire linkage plate 200 in a flat state. When the waste material in the pre-compression box 40 accumulates to a preset amount, the pre-compressed waste material enters the compression box 60; the lifting rod 110 drives the linkage plate 200 to move upward, and the first rotating plate 210 and the second rotating plate 220 rotate relative to each other. When waste falls into the collection box 10, a small amount of debris enters the exhaust box 50 from the first vent 51 and falls onto the linkage plate 200. When the first rotating plate 210 and the second rotating plate 220 rotate relative to each other, the debris on the linkage plate 200 falls into the bottom of the exhaust box 50. At this time, the sealing ball 90 leaves the second vent 52, and the debris in the exhaust box 50 can be discharged through the second vent 52. The cooperation between the second vent 52 and the sealing ball 90 can both vent and discharge, so that there will be no debris accumulation in the exhaust box 50.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
