[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-5This utility model provides a pre-treatment device for recycling waste lithium-ion batteries, including a crushing box 1; a discharge shell 3 is provided at the bottom of the crushing box 1; a discharge pipe 5 is provided on the side wall of the crushing box 1; a feeding shell 2 is rotatably connected to the top side wall of the crushing box 1; a rotating plate 21 is fixedly connected to the end of the feeding shell 2; a cylinder 22 is fixedly connected to the side wall of the rotating plate 21; a support frame 24 is fixedly connected to the side wall of the crushing box 1 on the side of the feeding shell 2; a motor 23 is fixedly connected to the middle of the support frame 24; a push plate 211 is installed at the end of the motor 23; and the push plate 211 is driven by the motor 23; the side wall of the push plate 211 contacts the side wall of the cylinder 22; multiple sets of sliding plates 26 are slidably connected to the middle of the feeding shell 2; an inclined plate 9 is fixedly connected to the middle of the top of the crushing box 1; the bottom of the inclined plate 9 contacts the outer wall of the feeding shell 2; during operation, a large number of waste lithium-ion batteries can be placed in the crushing box 2. The waste lithium-ion batteries will enter the middle of the feed shell 2 along the slope of the inclined plate 9 and accumulate on the top of the slide plate 26. At this time, the motor 23 can be started. The motor 23 will drive the push plate 211 to rotate. When the push plate 211 contacts the cylinder 22 fixed to the top of the rotating plate 21, it will push the cylinder 22 to move. At this time, the cylinder 22 will drive the rotating plate 21 to rotate. The rotating plate 21 will drive the feed shell 2 to rotate. Since the motor 23 is set at the eccentric position of the rotating plate 21, when the rotation of the rotating plate 21 moves the cylinder 22 to its bottom side, the push plate 211 will separate from the cylinder 22. At this time, the side filled with waste lithium-ion batteries will also face downward, pouring the lithium-ion batteries into the crushing roller in the middle of the crushing box 1. In this way, the rotating plate 21 can drive the feed shell 2 to rotate intermittently, which can reduce the risk of accumulation on the surface of the crushing roller and ensure its crushing effect.
[0027] Furthermore, such as Figures 2-3 and Figure 5As shown, a chute 6 is provided in the middle of the crushing box 1; an L-shaped plate 73 is slidably connected to the inner wall of the chute 6; a snap-fit strip 74 is fixed to the top of the L-shaped plate 73; a magnetic plate 7 is in contact with the side wall of the L-shaped plate 73; the magnetic plate 7 slides in the middle of the crushing box 1; a limiting groove 75 is provided on the side wall of the magnetic plate 7; the snap-fit strip 74 is inserted into the inner wall of the limiting groove 75; a vibration motor 77 is installed on the side wall of the L-shaped plate 73; springs 76 are symmetrically arranged in the middle of the chute 6; one end of the spring 76 is fixed to the side wall of the L-shaped plate 73; the other end of the spring 76 is fixed to the middle of the chute 6. During operation, the crushed lithium-ion batteries will fall onto the magnetic plate 7, while magnetic materials will be attracted to the top of the magnetic plate 7, and non-magnetic materials will pass through the discharge pipe 5 along the inclined surface of the magnetic plate 7 and be discharged. During this process, the vibration motor 77 can be activated to make the L-shaped plate 73 vibrate. When the L-shaped plate 73 is activated, the magnetic plate 7 vibrates via the snap-fit strip 74. This reduces the accumulation of non-magnetic materials on the top of the magnetic plate 7, improving its practicality. Furthermore, when it's necessary to remove material adsorbed on the top of the magnetic plate 7, the magnetic plate 7 can be stopped to cease vibration. Then, the protective strip 4 can be opened, allowing the magnetic plate 7 to be pulled into the center of the through hole 8. The through hole 8 and the magnetic plate 7 are completely in contact. When the magnetic plate 7 is pulled out, the inside of the crushing chamber 1 cleans the material on top of the magnetic plate 7, and the cleaned material is discharged through the discharge shell 3. After discharge, the magnetic plate 7 can be inserted back into the center of the crushing chamber 1, ensuring the snap-fit strip 74 is inserted into the center of the limiting groove 75, until the magnetic plate 7 is fully pushed into the center of the crushing chamber 1. Then, the protective strip 4 can be closed, allowing continued processing of waste lithium-ion batteries, further enhancing practicality.
[0028] Furthermore, such as Figure 4 As shown, a bidirectional threaded rod 25 is rotatably connected to the other end of the feeding shell 2; a movable plate 29 is threadedly connected to the outer wall of the bidirectional threaded rod 25; the movable plate 29 is slidably connected to the middle of the feeding shell 2; a fixing block 210 is fixedly connected to the top of the movable plate 29; a connecting plate 28 is rotatably connected to the middle of the fixing block 210; a hinge block 27 is fixedly connected to the bottom of the sliding plate 26; the other end of the connecting plate 28 is rotatably connected to the middle of the hinge block 27. During operation, if it is necessary to adjust the amount of material fed each time... The bidirectional threaded rod 25 can be rotated. At this time, the movable plate 29, which is threaded to the outer wall of the bidirectional threaded rod 25, will move linearly. The movable plate 29 will drive the fixed block 210 to move. At this time, the end of the connecting plate 28 will rotate with the fixed block 210, and at the same time, its other end will rotate with the hinge block 27. Through the hinge block 27, the sliding plate 26 will slide in the middle of the feeding shell 2. In this way, the loading depth of the feeding shell 2 will change, and the amount of material fed each time will also change, which improves practicality.
[0029] Furthermore, such as Figure 4 As shown, multiple sets of sliding plates 26 are provided, and the multiple sets of sliding plates 26 are symmetrically arranged with the center line of the lower shell 2 as the axis of symmetry. During operation, the multiple sets of sliding plates 26 move synchronously when adjusting their positions to ensure the consistency of material feeding on both sides of the lower shell 2.
[0030] Furthermore, such as Figure 1 and Figure 3 As shown, the motor 23 is specifically set at the eccentric position of the rotating plate 21. During operation, the motor 23 is set at the eccentric position of the rotating plate 21 to ensure that it can drive the rotating plate 21 to rotate intermittently, thus ensuring the material feeding speed.
[0031] Furthermore, such as Figures 1-2 As shown, the side wall of the crushing box 1 has a through hole 8; a protective strip 4 is fixedly connected to the side wall of the crushing box 1 by bolts; the protective strip 4 is specifically inserted into the middle of the through hole 8. During operation, the inner wall of the through hole 8 is in contact with the magnetic plate 7, ensuring that when the magnetic plate 7 is pulled out, the material adsorbed on the top of the magnetic plate 7 can be scraped off smoothly. In addition, by blocking the through hole 8 with the protective strip 4, the stability of the magnetic plate 7 in the middle of the crushing box 1 can be improved, and the material will not leak out, thus improving practicality.
[0032] Furthermore, such as Figure 3 As shown, a rectangular groove 71 is provided on the side wall of the magnetic plate 7; a pull plate 72 is rotatably connected to the middle of the rectangular groove 71. During operation, the magnetic plate 7 can be easily pulled out by the pull plate 72. When the magnetic plate 7 is in the middle of the crushing box 1, the pull plate 72 can be hidden in the inner wall of the rectangular groove 71 to ensure that the magnetic plate 7 can slide stably in the middle of the crushing box 1.
[0033] Working principle: A large number of waste lithium-ion batteries can be placed on the inner wall of the top of the crushing box 1. The waste lithium-ion batteries will then enter the middle of the feed shell 2 along the slope of the inclined plate 9 and accumulate on the top of the slide plate 26. At this time, the motor 23 can be started, which will drive the push plate 211 to rotate. When the push plate 211 contacts the cylinder 22 fixed to the top of the rotating plate 21, it will push the cylinder 22 to move. The cylinder 22 will then drive the rotating plate 21 to rotate, and the rotating plate 21 will drive the feed shell 2 to rotate. Since the motor 23 is set at the eccentric position of the rotating plate 21, when the rotation of the rotating plate 21 moves the cylinder 22 to its bottom side, the push plate 211 will separate from the cylinder 22. At this time, the side filled with waste lithium-ion batteries will also face downward, pouring the lithium-ion batteries onto the crushing roller in the middle of the crushing box 1. In this way, the rotating plate 21 can drive the feed shell 2 to rotate intermittently, which can reduce the risk of accumulation on the surface of the crushing roller and ensure its crushing effect.
[0034] If it is necessary to adjust the amount of material fed each time, the bidirectional threaded rod 25 can be rotated. At this time, the movable plate 29, which is threaded to the outer wall of the bidirectional threaded rod 25, will move linearly. The movable plate 29 will drive the fixed block 210 to move. At this time, the end of the connecting plate 28 will rotate with the fixed block 210, and at the same time, its other end will rotate with the hinge block 27. Through the hinge block 27, the sliding plate 26 will slide in the middle of the feeding shell 2. In this way, the loading depth of the feeding shell 2 will change, and the amount of material fed each time will also change, improving practicality.
[0035] The broken lithium-ion batteries will fall onto the magnetic plate 7. Magnetic materials will be attracted to the top of the magnetic plate 7, while non-magnetic materials will pass through the discharge pipe 5 along the inclined surface of the magnetic plate 7 and be discharged. During this process, the vibration motor 77 can be activated to make the L-shaped plate 73 vibrate. The L-shaped plate 73 will cause the magnetic plate 7 to vibrate through the clamping strip 74. This can reduce the accumulation of non-magnetic materials on the top of the magnetic plate 7 and improve practicality. In addition, when it is necessary to discharge the material attracted to the top of the magnetic plate 7, the magnetic plate 7 can be stopped to stop the vibration. Then, the bolt can be turned to open the protective strip 4, and then the pull plate 7 can be pulled out. One end of 2 is pulled out from the middle of the rectangular groove 71, so that the magnetic plate 7 can be pulled smoothly into the middle of the through hole 8. The through hole 8 and the magnetic plate 7 are completely in contact. When the magnetic plate 7 is pulled out, the inside of the crushing box 1 will clean the material on the top of the magnetic plate 7. The cleaned material will be discharged through the discharge shell 3. After discharge, the magnetic plate 7 can be inserted back into the middle of the crushing box 1. Make sure that the locking strip 74 is inserted into the middle of the limiting groove 75 until the magnetic plate 7 is completely pushed into the middle of the crushing box 1. Then close the protective strip 4, and the waste lithium-ion battery can continue to be processed, which improves the practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
