Description

Technical Field

[0001] This invention belongs to the field of dry cell battery decomposition and recycling technology, specifically a waste dry cell battery decomposition and recycling device. Background Technology

[0002] The battery manufacturing industry includes raw material mining, battery production, battery use, and battery recycling. Battery recycling and processing equipment is mainly used in the battery recycling and reuse process. Battery recycling and reuse can not only achieve the goal of energy conservation and resource conservation, but also reduce the pollution caused by batteries to the environment.

[0003] Patent CN214348556U discloses a dry cell battery recycling and processing device, including a housing, multiple support legs, multiple shock-absorbing pads, a crushing mechanism, a first motor, and a rotating shaft. The rotating shaft is driven by the first motor. The multiple support legs are fixedly installed at the bottom of the housing, and shock-absorbing pads are installed at the bottom of each support leg. A feeding channel is fixedly connected to the top of the housing, and a crushing mechanism is set below the feeding channel. This solution uses a second motor to rotate a crushing roller to crush the batteries. The rotating crushing roller drives a connecting rod and its connected ball to rotate, impacting the top of the first filter plate and the ball connected to the connecting rod, thereby causing the first filter plate to vibrate. By setting the first filter plate and the fixed plate to be connected by a spring, the first filter plate has a final vibration displacement, thereby increasing the filtering efficiency of the first filter plate for battery waste.

[0004] Dry cell batteries are mainly composed of end caps, carbon rods, electrolytes, and zinc casings. The end caps, carbon rods, electrolytes, and zinc casings are made of different materials. However, the above-mentioned solutions can only achieve a rough separation of metals and chemical substances, making it difficult to achieve fine recycling of materials and limiting the depth and efficiency of subsequent resource utilization. Therefore, this invention provides a waste dry cell battery decomposition and recycling device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A waste dry cell battery decomposition and recycling device of this invention includes a frame, two sets of sprockets rotatably mounted inside the frame, both sets of sprockets meshing with a chain, surrounding several sets of conveying blocks distributed on the outer ring of the chain. The conveying blocks have grooves for placing dry cell batteries. Guide covers are symmetrically arranged on both sides of the frame, and saw blades are rotatably mounted inside the guide covers. A carbon rod pin and an electrolyte pin are inserted into one side of the frame, both driven by a cylinder. A feeding mechanism is provided at one end of the frame, including two sets of support frames. A storage box is fixedly mounted on the support frames, a feeding plate is movably inserted into the storage box, and a receiving rod is fixedly connected to one side of the lower end of the feeding plate. A screw threaded onto the receiving rod is connected to the receiving rod. The lead screw is rotatably installed in the support frame and is fixedly connected to the material channel on one side of the storage box. Two sets of material channels are stacked and distributed. The lower end of one set of material channels is connected to a rectangular tube, and the lower end of the rectangular tube is attached to a set of conveying blocks. Two sets of through holes are opened on the other side of the frame. The two sets of through holes are used to insert carbon rod pins and electrolyte pins respectively. A pressure plate is fixedly installed between the two sets of guide covers. The lower end of the pressure plate is attached to the upper end of several sets of conveying blocks. The first recycling box is placed below the guide cover. The second recycling box and the third recycling box are placed below the two sets of through holes respectively. The fourth recycling box is placed below the other end of the frame. The upper end of the feeding plate is provided with a receiving groove for picking up materials. The side of the storage box is provided with a discharge hole, which is directly opposite the material channel. A discharge trough is provided in the material channel and is connected to the rectangular tube.

[0007] By setting up saw blades, carbon rod pins, and electrolyte pins, the dry cell battery is decomposed into end caps, carbon rods, electrolytes, and zinc casings. The end caps, carbon rods, electrolytes, and zinc casings are then collected one by one into the first, second, third, and fourth recycling boxes, making the recycling process of dry cell batteries more refined and facilitating subsequent processing of the recycled dry cell battery materials.

[0008] Preferably, the feeding plate is provided with a detection mechanism, which includes a base, the base being movably installed in the feeding plate, two sets of clamps symmetrically movably installed on the base, a movable block movably inserted into the base, two sets of springs symmetrically arranged in the base, a movable plate fixedly connected to the movable block, two sets of oblique grooves symmetrically opened on the movable plate, a pin set in the oblique groove, the pin being fixedly installed on a receiving frame, one end of the receiving frame being fixedly connected to the clamp, guide holes symmetrically opened on both sides of the base, the guide holes being slidably connected to a slide rod, the slide rod being fixedly installed in the feeding plate, one end of the spring being fixedly connected to the inner wall of the base, the other end of the spring being fixedly connected to the movable block, a guide groove being opened at the upper end of the base, a guide rail being provided at the lower end of the clamp, the guide rail being slidably connected to the guide groove, and a clearance hole for the clamp to pass through being opened in the receiving groove;

[0009] With the positive terminal of the dry cell battery facing the two sets of clamps, the clamps will hold the protrusion of the positive terminal cap, thus limiting the battery and preventing it from sliding into the material channel through the discharge hole. Then, during the retraction of the feeding plate, the clamps will release the battery, allowing it to return to the storage box. This process continues until the feeding plate retrieves the battery again, and it is no longer held by the clamps. This controls the position of the positive and negative terminals of the battery as it falls into the receiving trough, ensuring that the positive and negative terminal caps fall into the two sets of first recycling boxes respectively. This sorting of the positive and negative terminal caps facilitates the subsequent recycling and processing of the battery by the staff.

[0010] Preferably, the feeding plate is also provided with a linkage mechanism, which includes a toothed plate, the toothed plate is movably installed in the feeding plate, a guide plate is movably inserted into the toothed plate, a gear meshing with the toothed plate, the gear is rotatably installed in the feeding plate, a rack meshing with the gear, and a movable block is fixedly connected to the upper end of the rack. Two sets of rectangular sliding grooves are opened on both sides of the toothed plate, the rectangular sliding grooves are slidably connected to guide bars, the guide bars are fixedly installed in the feeding plate, a guide groove is opened on the guide plate, a receiving shaft is provided in the guide groove, the receiving shaft is fixedly installed in the toothed plate, and the guide groove is composed of an inclined sliding groove, a first vertical groove, and a second vertical groove.

[0011] The linkage mechanism reduces equipment investment and makes it easier for staff to use the device.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. By setting up saw blades, carbon rod pins, and electrolyte pins, the dry cell battery is decomposed into end caps, carbon rods, electrolytes, and zinc casings. The end caps, carbon rods, electrolytes, and zinc casings are then collected into the first, second, third, and fourth recycling boxes, making the recycling process of dry cell batteries more refined and facilitating subsequent processing of the recycled dry cell battery materials.

[0014] 2. As the dry cell batteries move upward with the feeding plate, they detach from the stacked dry cell batteries. Then, the moving block pushes the movable block, which, via springs, propels the base along the slide bar towards the clearance hole. The two sets of clamps pass through the clearance hole until the base is inserted and cannot move further. At this point, the movable block compresses the two sets of springs and pushes the movable plate to continue moving. The two sets of pins slide along the two sets of inclined grooves, guiding the two sets of clamps to move towards each other. Simultaneously, the two sets of clamps drive the corresponding guide rails to slide towards each other along the guide grooves. The positive terminal of the dry cell battery faces the two sets of clamps. The clamp will hold the protrusion of the positive terminal cap of the dry cell battery, limiting the dry cell battery and preventing it from sliding into the material channel through the discharge hole. Then, during the retraction of the feeding plate, the clamp will release the dry cell battery, allowing it to return to the storage box until the feeding plate picks up the dry cell battery again, and it can no longer be clamped by the two sets of clamps. This achieves control over the position of the positive and negative terminals of the dry cell battery falling into the receiving trough, so that the positive and negative terminal caps of the dry cell battery fall into the two sets of first recycling boxes respectively, realizing the classification of the positive and negative terminal caps of the dry cell battery, which facilitates the subsequent recycling and processing of the positive and negative terminal caps of the dry cell battery by the staff.

[0015] 3. As the dry cell battery moves upward with the feeding plate, components such as the toothed plate and the receiving shaft also move upward. Simultaneously, the receiving shaft slides along the first vertical groove. When the dry cell battery detaches from the storage bin, the receiving shaft slides into the inclined sliding groove, causing the toothed plate to move. The moving toothed plate causes the rack to move towards the detection mechanism, while the rack pushes the movable block, thus enabling the two sets of clamps to hold the protrusion of the positive terminal cap of the dry cell battery. Then, the receiving shaft slides upward along the second vertical groove until the dry cell battery is aligned with the discharge hole. The linkage mechanism reduces the investment in equipment and facilitates the use of the device by the staff. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1: As Figures 1 to 4As shown in the embodiment of the present invention, a waste dry cell battery decomposition and recycling device includes a frame 1. Two sets of sprockets 2 are rotatably installed inside the frame 1, and both sets of sprockets 2 are engaged with a chain 15. Several sets of conveying blocks 3 are distributed around the outer ring of the chain 15. The conveying blocks 3 have grooves 31 for placing dry cell batteries 17. Guide covers 4 are symmetrically arranged on both sides of the frame 1. Saw blades 5 are rotatably installed inside the guide covers 4. Carbon rod pins 7 and electrolyte pins 8 are inserted into one side of the frame 1. Both carbon rod pins 7 and electrolyte pins 8 are driven by cylinders 9. A feeding mechanism 16 is provided at one end of the frame 1. The feeding mechanism 16 includes two sets of support frames 161. A storage box 162 is fixedly installed on the support frame 161. A feeding plate 163 is movably inserted into the storage box 162. A receiving rod 164 is fixedly connected to one side of the lower end of the feeding plate 163. A screw 165 is screwed to the receiving rod 164. The screw 165 is rotatably installed on the support frame 161. Inside 61, a material channel 166 is fixedly connected to one side of the storage box 162. Two sets of material channels 166 are stacked and distributed. The lower end of one set of material channels 166 is connected to a rectangular tube 167. The lower end of the rectangular tube 167 is attached to a set of conveying blocks 3. Two sets of through holes 6 are opened on the other side of the frame 1. The two sets of through holes 6 are respectively used to insert carbon rod pins 7 and electrolyte pins 8. A pressure plate 13 is fixedly installed between the two sets of guide covers 4. The lower end surface of the pressure plate 13 is attached to the upper surface of several sets of conveying blocks 3. At the end face, a first recycling box 10 is placed below the guide cover 4, a second recycling box 11 and a third recycling box 12 are placed below the two sets of through holes 6 respectively, and a fourth recycling box 14 is placed below the other end of the frame 1. A receiving groove 43 for picking up materials is opened at the upper end of the feeding plate 163, and a discharge hole 21 is opened on one side of the storage box 162. The discharge hole 21 is directly opposite the material channel 166, and a discharge groove 61 is opened in the material channel 166. The discharge groove 61 is connected to the rectangular tube 167.

[0030] Specifically, the inner distance from the rectangular tube 167 to the saw blade 5 on the frame 1 is equal to the length of the dry cell battery 17, and the inner distance from the saw blade 5 to the fourth recycling box 14 is equal to the length of the dry cell battery 17 after the caps at both ends have been removed. The storage box 162 stores the dry cell battery 17, and the interface of the dry cell battery 17 stored in the storage box 162 is lower than the discharge hole 21. In the initial state, the upper end of the feeding plate 163 is located at the bottom of the storage box 162. When it is necessary to disassemble the dry cell battery 17, a set of lead screws 165 are driven by a motor to rotate, causing the receiving rod 164 to move the feeding plate 163 upward. As the feeding plate 163 moves, the dry cell batteries 17 stacked in the storage box 162 will be screened through the receiving groove 43 on the feeding plate 163. Dry cells that meet the requirements of the receiving groove 43 will be screened. The battery 17 will fall onto the receiving trough 43, and as the feeding plate 163 moves upward, until the receiving trough 43 is directly opposite the discharge hole 21, the dry cell battery 17 on the receiving trough 43 slides into the material channel 166 along the discharge hole 21, and then slides down into the unloading trough 61. It then falls into the rectangular tube 167 through the unloading trough 61, and the dry cell battery 17 falls into the groove 31 of a set of conveying blocks 3 along the inner cavity of the rectangular tube 167, thus feeding the dry cell battery 17. Then the feeding plate 163 is retracted, and simultaneously, another set of feeding plates 163 is driven by the motor to perform the same operation, so that the two sets of feeding plates 163 alternate feeding. During the feeding process, a set of sprockets 2 is driven by the motor to rotate, and the sprockets 2 drive the chain 15 and several sets of conveying blocks 3 to perform circular motion. Figure 3The middle arrow indicates the direction of circular motion. Simultaneously, two sets of saw blades 5 are driven by two sets of motors to rotate. The conveyor block 3 moves the dry cell battery 17 below the pressure plate 13, confining it between the pressure plate 13, the conveyor block 3, and the inner wall of the frame 1. During this movement, the two sets of saw blades 5 cut off the end caps of the dry cell battery 17, which fall into the first recycling box 10 through the guide cover 4. During this process, the dry cell battery 17 inside the rectangular tube 167 continues to fall into the groove 31 on the conveyor block 3 until it moves to the side of the carbon rod ejector pin 7. Conveying the dry cell battery 17 is then paused. The cylinder 9 drives the carbon rod ejector pin 7 to push the carbon rod inside the dry cell battery 17, causing it to fall through the corresponding through hole 6 into the second recycling box 11. Then, the dry cell battery 17 moves to the side of the electrolyte ejector pin 8. Following the same procedure, the electrolyte inside the dry cell 17 is pushed into the third recycling box 12, leaving only the zinc casing in the dry cell 17. The zinc casing continues to be conveyed by the conveyor block 3, and will detach from below the pressure plate 13. Under the action of gravity, the zinc casing will automatically fall into the fourth recycling box 14. The above operation is repeated to achieve the decomposition of the dry cell 17. Compared with the prior art, by setting the saw blade 5, carbon rod ejector pin 7, and electrolyte ejector pin 8, the dry cell 17 is decomposed into end caps, carbon rods, electrolytes, and zinc casings. The end caps, carbon rods, electrolytes, and zinc casings are then recycled one by one into the first recycling box 10, the second recycling box 11, the third recycling box 12, and the fourth recycling box 14. This makes the recycling and processing of the dry cell 17 more refined, which is beneficial for subsequent processing of the recycled materials from the dry cell 17.

[0031] Furthermore, the fourth recycling bin 14 is equipped with a shredding device 18.

[0032] Specifically, during the process of the zinc sheet automatically falling into the fourth recycling box 14, the zinc sheet will first fall into the shredding device 18 to shred the zinc sheet, and the shredded zinc sheet will fall into the fourth recycling box 14, reducing the space occupied by the zinc sheet.

[0033] like Figures 5 to 7As shown, a detection mechanism 168 is provided inside the feeding plate 163. The detection mechanism 168 includes a base 81, which is movably installed inside the feeding plate 163; two sets of clamps 82 symmetrically movably installed on the base 81; a movable block 83 movably inserted into the base 81; two sets of springs 84 symmetrically arranged inside the base 81; a movable plate 85 fixedly connected to the movable block 83; two sets of inclined grooves 86 symmetrically opened on the movable plate 85; and pins 87 arranged in the inclined grooves 86. The pins 87 are fixedly installed on the receiving frame 88. One end of the receiving frame 88 is fixedly connected to the clamp 82. The base 81 has symmetrical guide holes 811 on both sides. The guide holes 811 are slidably connected to the slide rod 89. The slide rod 89 is fixedly installed in the feeding plate 163. One end of the spring 84 is fixedly connected to the inner wall of the base 81. The other end of the spring 84 is fixedly connected to the movable block 83. The upper end of the base 81 has a guide groove 812. The lower end of the clamp 82 is provided with a guide rail 821. The guide rail 821 is slidably connected to the guide groove 812. The receiving groove 43 has a clearance hole 431 for the clamp 82 to pass through.

[0034] Specifically, the end caps of the dry cell battery 17 are divided into positive and negative terminals, and the materials used for the positive and negative end caps are different. Because the position of the positive and negative terminals of the dry cell battery 17 is uncontrollable when it falls into the receiving trough 43, the end caps in the first recycling box 10 are mixed together, which is not convenient for subsequent recycling of the end caps. In the initial state, the detection mechanism 168 is located in the feeding plate 163. Therefore, when the dry cell battery 17 falls into the receiving trough 43, the dry cell battery 17 moves upward with the feeding plate 163 to detach from the piled dry cell batteries 17, and then passes through a set of cylinders. Alternatively, the telescopic mechanism pushes the movable block 83, which, through the spring 84, pushes the base 81 along the slide rod 89 toward the clearance hole 431. The two sets of clamps 82 pass through the clearance hole 431 until the base 81 is inserted into the clearance hole 431 and cannot move further. At this time, the movable block 83 will compress the two sets of springs 84, and the movable block 83 will push the movable plate 85 to continue moving. The two sets of pins 87 will slide along the two sets of inclined grooves 86 respectively. Guided by the inclined grooves 86, the two sets of clamps 82 move toward each other. At the same time, the two sets of clamps... 82 drives the corresponding guide rail 821 to slide towards each other along the guide groove 812. At this time, if the negative terminal of the dry cell battery 17 faces the two sets of clamps 82, the two sets of clamps 82 cannot clamp the dry cell battery 17, and the dry cell battery 17 slides into the material channel 166 through the discharge hole 21, realizing the above-mentioned feeding of the dry cell battery 17. If the positive terminal of the dry cell battery 17 faces the two sets of clamps 82, the two sets of clamps 82 will clamp the protrusion of the positive terminal cap of the dry cell battery 17, so that the dry cell battery 17 is limited and cannot slide into the material channel 166 through the discharge hole 21. Then, during the process of retracting the feeding plate 163, the fixing of the dry cell battery 17 is released, allowing the dry cell battery 17 to return to the storage box 162 until the feeding plate 163 takes the dry cell battery 17 again and can no longer be clamped by the two sets of clamps 82. This achieves control over the positive and negative terminal positions of the dry cell battery 17 in the receiving trough 43, so that the positive and negative terminal caps of the dry cell battery 17 fall into the two sets of first recycling boxes 10 respectively, realizing the classification of the positive and negative terminal caps of the dry cell battery 17, which facilitates the subsequent recycling and processing of the positive and negative terminal caps of the dry cell battery 17 by the staff.

[0035] Example 2: Figure 8 and Figure 10As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a linkage mechanism 169 is also provided in the feeding plate 163. The linkage mechanism 169 includes a toothed plate 91, which is movably installed in the feeding plate 163. A guide plate 92 is movably inserted into the toothed plate 91, and a gear 93 meshes with the toothed plate 91. The gear 93 is rotatably installed in the feeding plate 163, and a rack 94 meshes with the gear 93. A movable block 83 is fixedly connected to the upper end of the rack 94. Two sets of rectangular sliding grooves 912 are provided on both sides of the toothed plate 91. The rectangular sliding grooves 912 are slidably connected to guide bars 913. The guide bars 913 are fixedly installed in the feeding plate 163. A guide groove 921 is provided on the guide plate 92. A receiving shaft 911 is provided in the guide groove 921. The receiving shaft 911 is fixedly installed in the toothed plate 91. The guide groove 921 is composed of an inclined sliding groove 211, a first vertical groove 212, and a second vertical groove 213.

[0036] Specifically, the aforementioned movable block 83 needs to be driven by a cylinder or telescopic mechanism. The cylinder or telescopic mechanism requires the assistance of a photoelectric sensor, increasing equipment costs. Furthermore, the feeding plate 163 needs to move up and down during operation, which is inconvenient for laying the air pipes and wires used in the cylinder or telescopic mechanism, making the device relatively cumbersome to use. Initially, the receiving shaft 911 is located at the bottom of the first vertical groove 212. When the dry cell battery 17 moves upward with the feeding plate 163, components such as the toothed plate 91 and the receiving shaft 911 move upward with the feeding plate 163. Simultaneously, the receiving shaft 911 moves along the first vertical groove 212. 12. When the dry cell battery 17 is removed from the storage box 162, the receiving shaft 911 slides into the inclined slide groove 211, causing the receiving shaft 911 to drive the toothed plate 91 to move. The moving toothed plate 91 causes the rack 94 to move towards the detection mechanism 168. At the same time, the rack 94 pushes the movable block 83, thereby enabling the two sets of clamps 82 to clamp the protrusion of the positive end cap of the dry cell battery 17. Then, the receiving shaft 911 slides upward along the second vertical groove 213 until the dry cell battery 17 is facing the discharge hole 21. The linkage mechanism 169 is designed to reduce the investment in equipment and facilitate the use of the device by the staff.

[0037] Working principle: A set of lead screws 165 driven by a motor rotates, causing the receiving rod 164 to move the feeding plate 163 upward. As the feeding plate 163 moves, the dry batteries 17 stacked in the storage box 162 will pass through the receiving groove 43 on the feeding plate 163 for screening. Dry batteries 17 that meet the requirements of the receiving groove 43 will fall onto the receiving groove 43. As the feeding plate 163 moves upward, until the receiving groove 43 is directly opposite the discharge hole 21, the dry batteries 17 on the receiving groove 43 slide along the discharge hole 21 into the material channel 166, and then... The material chute 166 slides into the feeding trough 61, and then into the rectangular tube 167. The dry cell battery 17 falls along the inner cavity of the rectangular tube 167 into the groove 31 of a set of conveying blocks 3, thus loading the dry cell battery 17. Then, the feeding plate 163 is retracted, and simultaneously, another set of feeding plates 163 is driven by a motor to perform the same operation, causing the two sets of feeding plates 163 to alternately load materials. During the loading process, a set of sprockets 2 is driven by a motor to rotate, and the sprockets 2 drive the chain 15, along with several sets of conveying blocks 3, to perform circular motion. Figure 3 The middle arrow indicates the direction of circular motion. Simultaneously, two sets of saw blades 5 are driven by two sets of motors to rotate. The conveyor block 3 moves the dry cell battery 17 below the pressure plate 13, confining the dry cell battery 17 between the pressure plate 13, the conveyor block 3, and the inner wall of the frame 1. During this movement, the two sets of saw blades 5 cut off the end caps of the dry cell battery 17, which fall into the first recycling box 10 through the guide cover 4. During this process, the dry cell battery 17 inside the rectangular tube 167 continues to fall into the groove 31 on the conveyor block 3 until it moves to the side of the carbon rod ejector pin 7, at which point the movement of the dry cell battery is paused. The dry cell 17 is conveyed by the cylinder 9, which drives the carbon rod ejector pin 7 to push the carbon rod inside the dry cell 17, causing the carbon rod to fall from the corresponding through hole 6 into the second recycling box 11. Then, the dry cell 17 is moved to the side of the electrolyte ejector pin 8. The same operation is performed to push the electrolyte inside the dry cell 17 into the third recycling box 12, leaving only the zinc shell in the dry cell 17. The zinc shell continues to be conveyed by the conveyor block 3. The zinc shell will fall off the pressure plate 13 and automatically fall into the fourth recycling box 14 under the action of gravity. The above operation is repeated to achieve the decomposition of the dry cell 17.

[0038] When the dry cell battery 17 falls into the receiving trough 43, it moves upward with the feeding plate 163, detaching from the stacked dry cell batteries. Then, a set of cylinders or telescopic mechanisms pushes the movable block 83. The movable block 83, through the spring 84, pushes the base 81 along the slide rod 89 towards the clearance hole 431. The two sets of clamps 82 pass through the clearance hole 431 until the base 81 is inserted into the clearance hole 431 and cannot move further. At this time, the movable block 83 will compress the two sets of springs 84, and the movable block 83 will push the movable plate 85 to continue moving. The two sets of pins 87 will slide along the two sets of inclined grooves 86 respectively. Under the guidance of the inclined grooves 86, the two sets of clamps 82 move towards each other. At the same time, the two sets of clamps 82 drive the corresponding guide rails 821 to slide towards each other along the guide groove 812. At this time, if the negative terminal of the dry cell battery 17 is facing the two sets of clamps 82, the two sets of clamps 82 will move towards each other. If clamp 82 cannot hold dry cell battery 17, dry cell battery 17 will slide into material channel 166 through discharge hole 21, thus achieving the above-mentioned feeding of dry cell battery 17. If the positive terminal of dry cell battery 17 faces the two sets of clamps 82, the two sets of clamps 82 will clamp the protrusion of the positive terminal cap of dry cell battery 17, thus limiting the dry cell battery 17. Dry cell battery 17 cannot slide into material channel 166 through discharge hole 21. Then, during the retraction of feeding plate 163, the fixation of dry cell battery 17 is released, allowing dry cell battery 17 to return to storage box 162 until feeding plate 163 takes dry cell battery 17 again and cannot be clamped by the two sets of clamps 82. This achieves control over the positive and negative terminal positions of dry cell battery 17 in receiving groove 43, so that the positive and negative terminal caps of dry cell battery 17 fall into the two sets of first recycling boxes 10 respectively, thus achieving the classification of positive and negative terminal caps of dry cell battery 17.

[0039] As the dry cell battery 17 moves upward with the feeding plate 163, components such as the toothed plate 91 and the receiving shaft 911 also move upward with the feeding plate 163. At the same time, the receiving shaft 911 slides along the first vertical groove 212. When the dry cell battery 17 is removed from the dry cell battery 17 accumulated in the storage box 162, the receiving shaft 911 will slide into the inclined slide groove 211, causing the receiving shaft 911 to drive the toothed plate 91 to move. The moving toothed plate 91 causes the rack 94 to move towards the detection mechanism 168. At the same time, the rack 94 pushes the movable block 83, thereby enabling the two sets of clamps 82 to clamp the protrusion of the positive end cap of the dry cell battery 17. Then, the receiving shaft 911 slides upward along the second vertical groove 213 until the dry cell battery 17 is facing the discharge hole 21.
