The conveying device can drive the waste battery to move left and right. The pressing structure includes multiple upper rollers spaced apart in the left-right direction, and the upper rollers are rotatably mounted above the conveying device. The feeding structure is installed to the right of the pressing structure, and the feeding structure can push the waste battery between the upper rollers and the conveying device. The upper rollers and the conveying device can jointly clamp the waste battery and drive it to move left and right. The two cutting structures are respectively installed on the front and rear sides of the pressing structure, and the cutting structures can cut the front and rear sides of the waste battery. The pressing and ejecting structure is installed to the left of the pressing structure, and the pressing and ejecting structure can press the aluminum shell onto the conveying device and eject the bare core inside the aluminum shell.

[0005] Furthermore, the conveying device includes a frame, a conveyor belt, and a support structure. The conveyor belt is movably mounted on the frame and includes an upper straight section. The support structure is disposed within the conveyor belt and supports the upper straight section.

[0006] Furthermore, the frame is provided with a first recovery tank for receiving electrolyte, the first recovery tank being located below the left side of the conveyor belt, and the frame is provided with second recovery tanks for receiving electrolyte on both the front and rear sides of the conveyor belt.

[0007] The outer wall of the conveyor belt has a plurality of first grooves and a plurality of second grooves. The plurality of second grooves are located in front of the plurality of first grooves. The plurality of first grooves and the plurality of second grooves are spaced apart along the circumferential direction of the conveyor belt. The side of the first groove away from the second groove is connected to the outside of the conveyor belt. The side of the second groove away from the first groove is connected to the outside of the conveyor belt. The front and rear ends of the conveyor belt are vertically aligned with the two second recycling troughs.

[0008] Furthermore, the first groove and the second groove are offset in the left-right direction.

[0009] Furthermore, a cover is connected to the top of the side of the second recycling trough away from the conveyor belt. The cover is located above the conveyor belt and extends towards the middle of the conveyor belt and above the conveyor belt, so that the cover can cover a portion of the conveyor belt.

[0010] Furthermore, the outer circumferential surface of the upper roller is provided with a plurality of elastic protrusions, which are spaced apart along the circumferential direction of the upper roller.

[0011] Furthermore, the clamping structure also includes a mounting base, which is movably mounted on the conveying device, and the upper roller is mounted on the mounting base.

[0012] Furthermore, the feeding structure includes:

[0038] Reference Figure 1 As shown, the waste battery cutting device provided in the embodiment of this utility model is used to cut waste batteries 100. The waste battery 100 includes an aluminum casing 101 and a bare coiled core 102 located inside the aluminum casing 101, as shown. Figure 2 , 3 As shown in Figure 4, the waste battery casing cutting equipment includes a conveying device 200, a clamping structure 300, a feeding structure 400, two cutting structures 500, and a clamping and ejecting structure 600. The conveying device 200 can drive the waste battery 100 to move left and right. The clamping structure 300 includes multiple upper rollers 310 spaced apart in the left-right direction, and the upper rollers 310 are rotatably mounted above the conveying device 200. The feeding structure 400 is installed to the right of the clamping structure 300, and the feeding structure 400 can push the waste battery 100 between the upper rollers 310 and the conveying device 200. The upper rollers 310 and the conveying device 200 can jointly clamp the waste battery 100 and drive it to move left and right. Figure 3 As shown, two cutting structures 500 are respectively installed on the front and rear sides of the pressing structure 300. The cutting structure 500 can cut the front and rear sides of the waste battery 100. The pressing and ejecting structure 600 is installed on the left side of the pressing structure 300. The pressing and ejecting structure 600 can press the aluminum shell 101 onto the conveying device 200 and eject the bare core 102 inside the aluminum shell 101.

[0039] This utility model, by setting up a conveying device 200, a pressing structure 300, a feeding structure 400, two cutting structures 500 and a pressing and ejecting structure 600, realizes the separation of aluminum shell 101 and bare core 102, so that subsequent processes can process aluminum shell 101 or bare core 102 separately, thereby avoiding the recycled battery powder containing more impurities and reducing the cost of impurity removal.

[0040] At work, such as Figure 4 As shown, the worker places the waste battery 100 on the feeding structure 400. The feeding structure 400 pushes the waste battery 100 between the upper roller 310 and the conveying device 200. Then, the upper roller 310 and the conveying device 200 together clamp the waste battery 100 and move it to the left. Figure 2 As shown, since the two cutting structures 500 are located on the front and rear sides of the clamping structure 300, during the movement of the waste battery 100, the two cutting structures 500 cut the front and rear sides of the waste battery 100, as shown. Figure 1 As shown, this allows the front and rear sides of the aluminum casing 101 to be connected to the outside; as Figure 4As shown, when the used battery 100 moves to the pressing and ejecting structure 600, the conveying device 200 stops driving the used battery 100 to move, and the pressing and ejecting structure 600 presses the aluminum casing 101 against the conveying device 200, as shown. Figure 1 As shown, since there is a gap between the outer sidewall of the bare core 102 and the inner sidewall of the aluminum shell 101, the bare core 102 may move when the aluminum shell 101 is fixed. As a result, the pressing and ejecting structure 600 can push the bare core 102 to move away from the aluminum shell 101, thereby separating the aluminum shell 101 and the bare core 102. The separated bare core 102 can be collected by the external first collection box. After the bare core 102 is collected, the pressing and ejecting structure 600 stops pressing the aluminum shell 101, and the conveying device 200 continues to drive the aluminum shell 101 to move, so that it falls into the external second collection box.

[0041] It is understandable that the front-to-back dimension of the waste battery 100 to be cut is larger than the front-to-back dimension of the pressing structure 300, thereby ensuring that the two cutting structures 500 located on the front and back sides of the pressing structure 300 can cut the front and back sides of the waste battery 100.

[0042] Specifically, the cutting structure 500 includes a first drive motor and a cutting blade. When the upper roller 310 and the conveying device 200 clamp the waste battery 100 together and drive it past the cutting blade, the first drive motor drives the cutting blade to rotate, and the cutting blade cuts the front or rear side of the waste battery 100.

[0043] Furthermore, such as Figure 1 , 4 As shown, the conveying device 200 includes a frame 210, a conveyor belt 220 and a support structure 230. The conveyor belt 220 is movably mounted on the frame 210. The conveyor belt 220 includes an upper straight section 221. The support structure 230 is disposed inside the conveyor belt 220 and supports the upper straight section 221.

[0044] With the support structure 230 provided, the upper straight section 221 can be supported, ensuring that the conveying device 200 and the upper roller 310 can clamp the waste battery 100 together and drive it to move.

[0045] Specifically, such as Figure 4 As shown, the conveying device 200 also includes a drive wheel 240, a driven wheel 250, and a second drive motor. The drive wheel 240 and the driven wheel 250 are rotatably mounted on the frame 210. The second drive motor is connected to the drive wheel 240. The support structure 230 consists of multiple lower rollers, which are rotatably mounted on the frame 210. The multiple lower rollers are spaced apart in the left-right direction and are located inside the conveyor belt 220 and between the drive wheel 240 and the driven wheel 250.

[0046] That is, the upper straight section 221 is supported by multiple lower rollers.

[0047] It is understandable that the upper roller 310 and the conveying device 200 (conveyor belt 220) can jointly clamp the waste battery 100 and drive it to move left and right, meaning that the gap between the upper roller 310 and the conveying device 200 is less than the vertical height of the waste battery 100, and the movement of the conveying device 200 drives the waste battery 100 to move at the same time. That is, the friction between the conveying device 200 and the waste battery 100 is greater than or equal to the friction between the waste battery 100 and the upper roller 310.

[0048] Specifically, such as Figure 4 As shown, multiple upper rollers 310 and multiple lower rollers are staggered in the left and right direction, and this structure can better clamp the waste battery 100.

[0049] Furthermore, such as Figure 1 , 5 As shown in Figure 6, the frame 210 is provided with a first recovery tank 211 for receiving electrolyte. The first recovery tank 211 is located below the left side of the conveyor belt 220. The frame 210 is provided with a second recovery tank 212 for receiving electrolyte on the front and rear sides of the conveyor belt 220.

[0050] The outer wall of the conveyor belt 220 has a plurality of first grooves 222 and a plurality of second grooves 223. The plurality of second grooves 223 are located in front of the plurality of first grooves 222. The plurality of first grooves 222 and the plurality of second grooves 223 are all spaced apart along the circumferential direction of the conveyor belt 220 (along the annular shape of the conveyor belt 220). The side of the first groove 222 away from the second groove 223 communicates with the outside of the conveyor belt 220, and the side of the second groove 223 away from the first groove 222 communicates with the outside of the conveyor belt 220. Figure 5 As shown, the front and rear ends of the conveyor belt 220 are aligned vertically with the two second recycling troughs 212.

[0051] like Figure 5 , 6 As shown, due to the presence of a first groove 222 and a second groove 223, and the fact that the front or rear end of the conveyor belt 220 corresponds to the position of the second recycling tank 212 in both the vertical and horizontal directions, when the waste battery 100 is cut, a portion of the electrolyte will flow through the first groove 222 or the second groove 223 to the second recycling tank 212 for electrolyte recovery; Figure 1 As shown, the first recycling tank 211 is located below the left side of the conveyor belt 220, so that another part of the electrolyte remaining on the surface of the belt (or the electrolyte remaining in the first groove 222 or the second groove 223) falls freely into the first recycling tank 211 as the conveyor belt 220 runs.

[0052] The aforementioned structure enables the waste battery casing cutting equipment to recycle electrolyte.

[0053] Specifically, such as Figure 5 As shown, both the front and rear ends of the outer wall of the conveyor belt 220 have downwardly sloping guide slopes 224. By providing guide slopes 224, the electrolyte can more easily enter the second recovery tank 212.

[0054] Furthermore, such as Figure 6 As shown, the first groove 222 and the second groove 223 are staggered in the left and right direction, which makes the electrolyte collection faster and eliminates the need to design more first grooves 222 or second grooves 223.

[0055] Furthermore, such as Figure 5 As shown, a cover 213 is connected to the top of the side of the second recycling tank 212 away from the conveyor belt 220. The cover 213 is located above the conveyor belt 220 and extends towards the middle of the conveyor belt 220 and extends above the conveyor belt 220, so that the cover 213 can cover a part of the conveyor belt 220 (the front end or the rear end of the conveyor belt 220).

[0056] The cover 213 is provided to prevent the cut aluminum sheet from entering the second recycling tank 212.

[0057] Furthermore, such as Figure 4 As shown, the outer circumferential surface of the upper roller 310 is provided with a plurality of elastic protrusions 311, which are spaced apart along the circumferential direction of the upper roller 310.

[0058] It is understandable that the elastic protrusion 311 can deform under force.

[0059] By incorporating deformable elastic protrusions 311, friction is increased to prevent the waste battery 100 from moving during cutting.

[0060] Specifically, the elastic protrusion 311 is a rubber nail. It is conceivable that the elastic protrusion 311 could also be made of other materials while still preventing the waste battery 100 from moving.

[0061] Furthermore, such as Figure 4 As shown, the clamping structure 300 also includes a mounting base 320, which is movably mounted on the conveying device 200, and the upper roller 310 is mounted on the mounting base 320.

[0062] Since the upper roller 310 can move up and down through the mounting base 320, the gap between the upper roller 310 and the conveyor belt 220 can be adjusted, thereby better clamping the waste battery 100 or adapting to waste batteries 100 of different sizes.

[0063] Specifically, the mounting base 320 is mounted on the conveying device 200 in a way that allows it to move up and down via height adjustment bolts, or the conveying device 200 is equipped with four rectangularly distributed and rotatable lead screws, and a portion of the mounting base 320 is threadedly connected to the four lead screws, so that the vertical position of the mounting base 320 can be adjusted by rotating the four lead screws.

[0064] Furthermore, the feed structure 400 includes:

[0065] like Figure 1 As shown, the support platform 410 is installed on the right side of the conveyor 200;

[0066] like Figure 2 As shown, four fixed guide rods 420 are installed on the top of the support platform 410 in a rectangular arrangement, and multiple waste batteries 100 can be stacked between the four fixed guide rods 420.

[0067] like Figure 4 As shown, the baffle 430 is located to the left of the four fixed guide rods 420. The position of the baffle 430 corresponds to the position of the second waste battery 100 (α) counting from the bottom of the fixed guide rod 420.

[0068] like Figure 4 As shown, the pushing device 440 is installed on the support platform 410. The pushing device 440 is located to the right of the four fixed guide rods 420. The pushing device 440 can push the first waste battery 100 (β) counting from the bottom to the top of the fixed guide rods 420 to the space between the upper roller 310 and the conveying device 200.

[0069] The feeding structure 400 adopts the above structure, which enables the feeding structure 400 to store multiple waste batteries 100 and to push the waste batteries 100 one by one between the upper roller 310 and the conveying device 200.

[0070] During operation, workers stack multiple used batteries 100 on four fixed guide rods 420. Then, the pushing device 440 is activated, pushing the last used battery 100 between the upper roller 310 and the conveying device 200. The pushing device 440 then pushes out the used batteries 100 one by one.

[0071] It is understandable that the first waste battery 100 (β) or the second waste battery 100 (α) mentioned above are counted from bottom to top.

[0072] Specifically, the pushing device 440 is a cylinder. The cylinder can push only half of the waste battery 100 between the upper roller 310 and the conveying device 200. Then, the waste battery 100 is moved out of the feeding structure 400 by the drive of the conveying device 200. By adopting the above-mentioned pushing method, the penultimate waste battery 100 can fall normally and the cylinder can retract normally.

[0073] Specifically, such as Figure 8 The support platform 410 is equipped with a photoelectric switch 411, which works in conjunction with the feeding device 440. The photoelectric switch 411 is used to detect the last waste battery 100.

[0074] Specifically, the baffle 430 is mounted on the support platform 410 via a gantry frame. The gantry frame has a moving channel for the waste battery 100 to move left and right on the support platform 410. The first waste battery 100 (β) counting from the bottom to the top of the fixed guide rod 420 can be moved out from the moving channel and into the space between the upper roller 310 and the conveying device 200.

[0075] Furthermore, such as Figure 3 , 8 As shown, the fixed guide rod 420 is movably mounted on the support platform 410, and the cutting structure 500 is movably mounted on the conveying device 200.

[0076] All four fixed guide rods 420 can move back and forth, allowing the rear fixed guide rod 420 and the front fixed guide rod 420 to move synchronously. This enables the positioning of the waste battery 100 within the four fixed guide rods 420, allowing the feeding structure 400 to adapt to waste batteries 100 of different sizes and ensuring that the waste battery 100 can be accurately clamped and cut. The cutting structure 500 can also move back and forth, allowing the cutting structure 500 to adjust its position according to the size of the waste battery 100, thus adapting to waste batteries 100 of different sizes.

[0077] Specifically, an adjustment rail 214 extending in the front-to-back direction is installed on the frame 210, and the cutting structure 500 is movably installed on the adjustment rail 214.

[0078] Specifically, two electric push rod assemblies 412 are installed on the support platform 410. The two electric push rod assemblies 412 are spaced apart. The rear electric push rod assembly is connected to two rear fixed guide rods 420, and the front electric push rod assembly is connected to two front fixed guide rods 420. The electric push rod assembly 412 can drive the fixed guide rods 420 to move back and forth.

[0079] Furthermore, such as Figure 1 , 9As shown, the pressing and ejecting structure 600 includes a support frame 610, a first cylinder 620, and a second cylinder 630. The support frame 610 is installed above the conveying device 200, and the first cylinder 620 is installed at the bottom of the support frame 610. The first cylinder 620 can press the aluminum shell 101 onto the conveying device 200. The second cylinder 630 is installed on the front or rear side of the conveying device 200 and can eject the bare core 102 inside the aluminum shell 101.

[0080] At work, such as Figure 2 As shown, the conveying device 200 moves the waste battery 100 to the left. When the waste battery 100 moves below the first cylinder 620, the conveying device 200 stops working. Figure 9 As shown, the telescopic rod of the first cylinder 620 extends, and the first cylinder 620 presses the aluminum shell 101 onto the conveying device 200. Then, the telescopic rod of the second cylinder 630 extends, and the second cylinder 630 pushes the bare core 102 out of the aluminum shell 101. After the push is completed, the first cylinder 620 and the second cylinder 630 reset, and the conveying device 200 drives the aluminum shell 101 to move to the left.

[0081] Specifically, such as Figure 3 As shown, the second cylinder 630 is installed on the rear side of the conveying device 200, and the front side of the conveying device 200 is equipped with a guide groove 260. The second cylinder 630 can push the bare core 102 into the guide groove 260 for collection.

[0082] Specifically, the support frame 610 is a gantry structure (not shown in the figure). The gantry structure includes a horizontal section extending in the front-to-back direction and two vertical sections extending in the up-down direction. The two vertical sections are respectively placed at the bottom of the front and rear sides of the horizontal section. The bottom of the two vertical sections is installed on the frame 210 and is located at the front and rear sides of the conveyor belt 220. The horizontal section is located above the conveyor belt 220. The first cylinder 620 is installed at the bottom of the horizontal section, and the horizontal section supports the first cylinder 620, so that the first cylinder 620 is located above the conveyor belt 220. The second cylinder 630 is installed at the top of the frame 210 and is located behind the conveyor belt 220. The second cylinder 630 is offset from the vertical section in the left-to-right direction.

[0083] Specifically, two cutting structures 500 are located inside a sealing cover 700, which has a communication port on which a pneumatic butterfly valve 710 is installed.

[0084] During operation, external nitrogen gas enters the sealing cover 700 through the pneumatic butterfly valve 710 and the connecting port, ensuring cutting safety.

[0085] When this utility model is in operation:

[0086] like Figure 3As shown, workers stack multiple used batteries 100 within four fixed guide rods 420, as... Figure 8 As shown, the rear electric push rod assembly 412 pushes the two rear fixed guide rods 420 forward, and the front electric push rod assembly 412 pushes the two front fixed guide rods 420 backward to center the multiple waste batteries 100.

[0087] like Figure 4 As shown, the drive mounting base 320 moves up and down, and the gap between the upper roller 310 and the conveyor belt 220 is adjusted to ensure that the upper roller 310 and the conveyor belt 220 clamp the waste battery 100 together and can drive it to move. The positions of the two cutting structures 500 in the front and back directions are adjusted to ensure that the front and back sides of the waste battery 100 can be cut.

[0088] Photoelectric switch 411 detects the last discarded battery 100, such as Figure 4 As shown, the feeding device 440 is started, and the feeding device 440 pushes the last waste battery 100 between the upper roller 310 and the conveyor belt 220. The upper roller 310 and the conveyor belt 220 clamp the waste battery 100 and drive it to move to the left (the conveyor belt 220 moves, and in turn, the conveyor belt 220 drives the waste battery 100 to move to the left, and at the same time, the multiple upper rollers 310 also rotate as the waste battery 100 moves). When the waste battery 100 passes through the two cutting structures 500, the two cutting structures 500 cut the front and rear sides of the waste battery 100 respectively.

[0089] like Figure 9 As shown, when the conveyor belt 220 drives the waste battery 100 to move below the first cylinder 620, the conveyor belt 220 stops working, the telescopic rod of the first cylinder 620 extends, and the first cylinder 620 presses the aluminum shell 101 onto the conveyor belt 220. Then the telescopic rod of the second cylinder 630 extends, and the second cylinder 630 pushes the bare core 102 out of the aluminum shell 101. After the push is completed, the first cylinder 620 and the second cylinder 630 reset, and the conveyor belt 220 drives the aluminum shell 101 to move to the left.

[0090] During the cutting process or after the cutting structure 500 is completed, the pushing device 440 pushes the second-to-last waste battery 100 between the upper roller 310 and the conveyor belt 220.
