[0025] Furthermore, in order to increase the amount of heat shrinkable films collected by the collecting bin 304 , a heating wire is provided at the bottom of the collecting bin 304 , and both ends of the heating wire are respectively connected to the positive and negative terminals of the discharger 10 .

[0026] The lithium battery 6 is cylindrical, and the surface of the lithium battery 6 is wrapped with a layer of heat shrink film. The following is a detailed description of the discharge and crushing process of the waste lithium battery 6: First, place the lithium battery 6 horizontally, with the positive electrode of the lithium battery 6 facing the front and the negative electrode facing the rear, and then place the lithium battery 6 in the storage cavity 5001 between the front limiting plate 51 and the rear limiting plate 52 in sequence. At this time, the positive electrode of the lithium battery 6 is in contact with the conductive plate of the front limiting plate 51, and the negative electrode of the lithium battery 6 is in contact with the conductive plate of the rear limiting plate 52. The second driving member 207 is controlled to drive the lever 202 to move to the left, so that the lever 202 protrudes from the second baffle 206, thereby preventing the lithium battery 6 at the bottom of the storage cavity 5001 from falling into the discharge cavity 9001. Then, the discharger 10 is controlled to open, so that the positive and negative electrodes of the lithium battery 6 are connected to the two ends of the resistance wire 203 respectively. The lithium battery 6 is put in a short-circuit state, thereby converting the residual electric energy in the lithium battery 6 into heat energy on the resistance wire 203, so as to achieve the effect of rapid discharge of the lithium battery 6. The voltage value between the front limit plate 51 and the rear limit plate 52 is detected by a voltage detector arranged in the discharger 10. When the voltage value drops to the set threshold value, it can be determined that the discharge of the lithium battery 6 is completed, and then the second driving member 207 is controlled to drive the lever 202 to move to the right, so that the lever 202 is retracted to the bottom of the second baffle 206, so that the lithium battery 6 at the bottom of the storage cavity 5001 falls into the discharge cavity 9001 in turn, and through the limitation of the top plate 9, the first baffle 205 and the second baffle 206, from a front to back perspective, as shown Figure 3As shown, the lithium batteries 6 in the discharge chamber 9001 are stacked to a vertical state, the lithium battery 6 at the bottom is fitted with the bottom plate 7001, and the center positions of the top block 8 and the first driving member 201 are aligned with the center of the lithium battery 6, and then the first driving member 201 is controlled to drive the top block 8 to move left, and the lock 9002 is controlled to be in an unlocked state, so that the top plate 9 can slide in the lock 9002, so that the top block 8 pushes the lithium battery 6 and the top plate 9 to move left, so that the spring between the top plate 9 and the fixed plate 7 is compressed until the lithium battery 6 at the bottom is separated from the bottom plate 7001, and the lithium battery 6 is lifted up under its own weight. Under the action of the first driving member 201, the lithium battery 6 in the discharge chamber 9001 falls downward and then falls between the two crushing rollers 3. Then, the asynchronous motor on the crushing roller 3 is controlled to start, and the crushing roller 3 on the left rotates clockwise and the crushing roller 3 on the right rotates counterclockwise, and the lithium battery 6 is crushed into fragments by the reverse rotation of the two crushing rollers 3. Then, the lithium battery 6 fragments fall into the collection box 2. In addition, in the process of the first driving member 201 driving the top block 8 to move to the left, the second driving member 207 is synchronously controlled to drive the lever 202 to move to the left, so that the lever 202 protrudes from the second baffle 206, blocking the storage The lithium battery 6 in the cavity 5001 falls into the discharge cavity 9001. When the lithium battery 6 in the discharge cavity 9001 falls, the first driving member 201 is controlled to drive the top block 8 to return to the initial position. At the same time, the top plate 9 is reset to the initial position under the action of the spring. Then the second driving member 207 is controlled to drive the lever 202 to retract, so that the lithium battery 6 at the bottom of the storage cavity 5001 falls into the discharge cavity 9001. In this way, the continuous crushing of the lithium battery 6 can be achieved. Compared with the conventional lithium battery 6 recycling method, the lithium battery 6 in the storage cavity 5001 is short-circuited by using the resistance wire 203, thereby achieving the lithium battery 6. The rapid discharge eliminates the process of soaking the lithium battery 6 in salt water, shortens the time for recovering the lithium battery 6, and at the same time, by arranging a current protector inside the discharger 10, when the discharge current of the lithium battery 6 exceeds the threshold of the current protector, the current protector fuses, thereby blocking the lithium battery 6 from continuing to discharge, avoiding the risk of thermal runaway of the lithium battery 6 due to high current discharge. On this basis, in the process of crushing the lithium battery 6 by the crushing roller 3, the lithium battery 6 can be added to the storage chamber 5001 simultaneously, thereby realizing the simultaneous discharge and crushing of the lithium battery 6, thereby improving the recovery efficiency of the lithium battery 6.

[0027] During the continuous discharge of the lithium battery 6, the inside of the lithium battery 6 is prone to heat up, and since the lithium batteries 6 in the storage cavity 5001 are stacked on each other, the heat of the lithium battery 6 in the middle is difficult to dissipate, which can easily cause the temperature of the lithium battery 6 to continue to rise, and then spontaneous combustion occurs. For this reason, a gap 5002 is provided between the front limiting plate 51 and the rear limiting plate 52 to increase the contact area between the lithium battery 6 and the outside air, thereby facilitating the lithium battery 6 to dissipate heat to the outside and avoiding the lithium battery 6 from spontaneous combustion due to excessively high temperature.

[0028] Since the models of recycled lithium batteries 6 are different, with different lengths and different diameters, different lithium batteries 6 need to be classified before crushing. On this basis, the support rod 4 is set as an electric push rod. Before placing the lithium battery 6, the support rod 4 can be used to adjust the distance between the front limit plate 51 and the rear limit plate 52, so that the storage cavity 5001 can adapt to lithium batteries 6 of different lengths, thereby improving the adaptability to the lithium battery 6. Furthermore, by setting the slide 204 to slide left and right on the fixed plate 7, the first baffle plate 205 and the second baffle plate 206 slide left and right on the fixed plate 7, thereby manually adjusting the position of the fixed plate 7 on the slide 204, thereby adjusting the distance between the top plate 9 and the first baffle plate 205. The spacing makes the space of the discharge cavity 9001 adaptable to the diameter of the lithium battery 6. At the same time, by setting the first driving member 201 to slide in the corresponding adjustment groove 7002, it is convenient to manually adjust the center distance between two adjacent first driving members 201, so that the center distance between two adjacent first driving members 201 is consistent with the center distance between two adjacent lithium batteries 6, so that it is convenient for the top block 8 to push the lithium battery 6 to move to the left, and by setting the first baffle plate 205 to slide in the corresponding through groove of the slide 204, it is convenient to manually adjust the distance between two adjacent first baffle plates 205, so that the distance between two adjacent first baffle plates 205 is adaptable to the center distance between two adjacent lithium batteries 6.

[0029] Since the surface of the lithium battery 6 is wrapped with a layer of heat shrink film, when the lithium battery 6 is crushed, the heat shrink film is usually crushed together, and in the subsequent processing of the lithium battery 6, the heat shrink film is separated and processed separately. In this way, it is necessary to add an additional device for separating the heat shrink film, thereby increasing the recycling cost. In addition, during the crushing process, the electrolyte in the lithium battery 6 is easily attached to the heat shrink film, thereby increasing the subsequent cleaning work of the heat shrink film. For this reason, by installing the first cutter 301 and the clamping plate 302 on the two top blocks 8 at the same height, the first cutter 301 replaces the top block 8 to push the lithium battery 6 to move, and before the first driving member 201 drives the top block 8 and the first cutter 301 to move to the left, the lock 9002 is first controlled to be in a locked state, so that the top plate 9 The first drive member 201 is then controlled to drive the first cutter 301 and the clamping plate 302 to move to the left, so that the first cutter 301 squeezes the lithium battery 6 to the left. At the same time, the first cutter 301 is powered by an external power supply device to increase the temperature of the blade of the first cutter 301, and then the heat shrink film on the surface of the lithium battery 6 is heated by the high temperature at the blade, so that the contact surface between the heat shrink film and the blade of the first cutter 301 shrinks, thereby disconnecting the heat shrink film, and then turning off the power of the first cutter 301, and then controlling the lock 9002 to be in an unlocked state, so that the top plate 9 can slide in the lock 9002, so that the first cutter 301 pushes the lithium battery 6 and the top plate 9 to move to the left. In this process, due to the two second cutters The blade spacing of the knife 303 is equal to the width of the storage cavity 5001, that is, the two second cutters 303 are respectively aligned with the front center and the rear center of the adjacent lithium battery 6. As the lithium battery 6 moves to the left, the two second cutters 303 respectively contact the front and rear parts of the heat shrink film on the surface of the lithium battery 6, and the front and rear parts of the heat shrink film are cut off by the second cutter 303. At this time, the heat shrink film is in a completely disconnected state, and the heat shrink film located at the lower side of the first cutter 301 falls to the right between the first cutter 301 and the clamping plate 302 after being disconnected. At the same time, as the first cutter 301 and the second cutter 303 move to the left, the slide groove 30201 is synchronously driven to move to the left, so that the slide groove 30201 and the guide block 2 0501 contacts, and then guides the clamping plate 302 to move upward through the guide block 20501, and the spring between the clamping plate 302 and the first cutter 301 is stretched until the clamping plate 302 and the first cutter 301 fit each other, thereby clamping the heat shrink film between the clamping plate 302 and the first cutter 301, and as the clamping plate 302 and the first cutter 301 continue to move to the left, until the lithium battery 6 is separated from the bottom plate 7001, the lithium battery 6 falls downward, so that in the process of pushing the lithium battery 6 out of the discharge cavity 9001, the heat shrink film is separated by the clamping plate 302 and the first cutter 301, avoiding the subsequent separation process of the heat shrink film separately, improving the separation efficiency, reducing the recycling cost, and reducing the subsequent cleaning work of the heat shrink film. In this process,When the clamping plate 302 and the first cutter 301 clamp the heat shrink film, since a heat insulating plate 30101 is provided at the lower side of the first cutter 301, the heat insulating plate 30101 replaces the first cutter 301 to cooperate with the clamping plate 302 to clamp the heat shrink film, so as to prevent the heat on the first cutter 301 from being transferred to the heat shrink film, causing the heat shrink film to overheat and melt and adhere to the first cutter 301. When the lithium battery 6 falls downward, the first cutter 301 and the clamping plate 302 are driven to move to the right by the first driving member 201, thereby bringing The heat shrink film is moved to the right, and the top plate 9 is reset. At this time, the heat shrink film is located in the discharge chamber 9001. Then, the first cutter 301 and the clamping plate 302 are moved to the right to the initial position, so that the slide groove 30201 is disengaged from the guide block 20501, and the spring between the first cutter 301 and the second cutter 303 is reset, so that the second cutter 303 moves downward, so that the heat shrink film loses its clamping, and the heat shrink film moves downward to the upper surface of the bottom plate 7001. Based on the view from front to back, the control motor 305 drives the The bottom plate 7001 is driven to rotate counterclockwise, so that the heat shrink film on the upper surface of the bottom plate 7001 falls into the collecting bin 304, and then the bottom plate 7001 is controlled to reset and move to collect the heat shrink film. In addition, when a lot of heat shrink film is accumulated under the bottom plate 7001, the motor 305 drives the bottom plate 7001 to rotate counterclockwise to push the heat shrink film under the bottom plate 7001 backward so that the heat shrink film is close to the discharge port 30402. When a lot of heat shrink film is accumulated inside the collecting bin 304, the external air extraction device is used to remove the heat shrink film. Start to evacuate the discharge port 30402, and use the negative pressure generated by the evacuation to suck away the heat shrink film around the discharge port 30402, thereby replacing the manual collection of the heat shrink film in the collection bin 304, reducing the workload of manual cleaning. In addition, since the middle of the collection bin 304 is provided with a telescopic portion 30401, when the distance between the front limit plate 51 and the rear limit plate 52 changes, the telescopic portion 30401 is adaptively expanded and contracted, thereby ensuring that the space of the collection bin 304 can adapt to the size of the lithium battery 6.

[0030] In the above-mentioned work of adjusting the distance between the front limit plate 51 and the rear limit plate 52 by the support rod 4, and then adjusting the width of the storage cavity 5001 to adapt to lithium batteries 6 of different lengths, the movement of the front limit plate 51 and the rear limit plate 52 synchronously drives the two fixed plates 7 to move, and then synchronously drives the slide 204 and the second cutter 303 to move forward or backward, so as to achieve synchronous adjustment of the blade distance of each corresponding second cutter 303, and then adapt to the film cutting work of lithium batteries 6 of different lengths, and the movement of the fixed plate 7 will drive the first drive member 201 and the top block 8 to move synchronously, so that the top block 8 slides back and forth on the first cutter 301.

[0031] On this basis, since a heating wire is provided at the bottom of the collecting bin 304, when the lithium battery 6 is discharged, the temperature of the heating wire increases, thereby increasing the temperature of the bottom of the collecting bin 304, and then causing the heat shrink film in the collecting bin 304 to shrink due to the heat, thereby reducing the space occupied by the heat shrink film, thereby increasing the amount of heat shrink film collected in the collecting bin 304.

[0032] Example 2 On the basis of Example 1, Figure 1 and Figure 2 As shown, it also includes a water pipe 401; two left-right symmetrical water pipes 401 are fixedly connected to the fixed frame 1; each water pipe 401 is located above the adjacent crushing rollers 3; each water pipe 401 is provided with a plurality of drainage holes, and the drainage holes face between the two crushing rollers 3; the two water pipes 401 are connected to an external water supply device.

[0033] Furthermore, in order to improve the recycling rate of residual electricity in the lithium battery 6, a cavity is opened on the side wall of the collection box 2, and the resistance wire 203 is located in the cavity of the collection box 2, so that the heat energy generated by the resistance wire 203 is gathered in the collection box 2, and then the lithium battery 6 fragments are dried by the heat energy in the collection box 2.

[0034] When the first cutter 301 squeezes the lithium battery 6, the heat on the first cutter 301 will be transferred to the lithium battery 6, causing the surface temperature of the lithium battery 6 to rise. In addition, during the crushing of the lithium battery 6 by the crushing roller 3, the electrolyte of the crushed lithium battery 6 is easily attached to the surface of the crushing roller 3. Since the crushing roller 3 is constantly rubbing against the lithium battery 6, and the surface temperature of the lithium battery 6 is high, it is easy for the flammable organic matter in the electrolyte to burn and produce harmful gases. At the same time, the lithium battery 6 will produce some lithium battery 6 fragments during the crushing process. These fragments contain electrolyte and are polluting. The debris of lithium battery 6 can easily float into the air, thus causing air pollution and making the working environment of the staff worse. For this reason, water is transported into the water pipe 401 through an external water supply device, so that the water is sprayed out from the drainage hole in the form of water mist, thereby spraying onto the lithium battery 6 between the two crushing rollers 3. The debris of lithium battery 6 is moistened by the water mist to prevent the debris of lithium battery 6 from escaping everywhere, thereby avoiding air pollution and improving the working environment of the staff. In addition, the surface of the crushing roller 3 and the lithium battery 6 are cooled by the water mist to prevent the flammable organic matter in the electrolyte from burning.

[0035] On this basis, when the lithium battery 6 is moistened during the crushing process, its fragments contain moisture, which makes it inconvenient to subsequently separate the lithium battery 6 fragments. For this reason, when the lithium battery 6 is discharged, the electrical energy in the lithium battery 6 is converted into thermal energy of the resistance wire 203. By setting the resistance wire 203 to be located in the cavity of the collection box 2, the thermal energy is gathered in the collection box 2, and then the thermal energy in the collection box 2 is used to dry the lithium battery 6 fragments, thereby facilitating the subsequent separation of the lithium battery 6 fragments. Compared with the conventional drying method, the thermal energy generated by the discharge of the lithium battery 6 is used to dry the moisture in the lithium battery 6 fragments, thereby realizing the recycling of the residual electricity in the lithium battery 6, improving the recycling rate of the lithium battery 6, and reducing the electrical energy required for drying the lithium battery 6 fragments, thereby reducing the recycling cost.
