Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to an automatic feeding device. Background Technology

[0002] In the process of dry electrode preparation, various substances such as conductive agents (e.g., graphite) and binders (e.g., PTFE, polytetrafluoroethylene) are first mixed and fiberized to form dry lithium battery granules. These granules are then rolled into electrode films, which are then laminated onto the surface of the current collector to obtain the dry electrode. Currently, a hot rolling mill is generally used to roll the dry lithium battery granules into electrode films. Specifically, the dry lithium battery granules are first fed into the guide groove of the inclined guide plate of the hot rolling mill via an automatic feeding device. The granules then flow along the guide groove into the feed trough of the hot rolling mill, and subsequently into the roll gap between the two rolls. The two rolls then rotate in opposite directions, thus rolling the granules into electrode films.

[0003] The aforementioned automatic feeding equipment generally includes two opposing supports, a hopper mechanism for pre-storing dry-process lithium battery granules, a vibrator, and a conveyor plate. The hopper mechanism is located above and connected to the two supports. The top and bottom of the hopper mechanism are respectively provided with an inlet and an outlet communicating with the interior of the hopper mechanism. The vibrator is positioned between the two supports, and the conveyor plate is located below the hopper mechanism. The conveyor plate is positioned on top of the vibrator, with one end protruding from one side of the two supports. The top of the conveyor plate has a conveying trough, with the inlet end of the trough corresponding to the outlet end, and the outlet end of the trough extending to one end of the conveyor plate. One end of a guide plate is located below one end of the conveyor plate. In practical applications, operators feed dry-process lithium battery granules into the hopper mechanism through the inlet. The granules then discharge from the outlet under their own gravity and enter the inlet end of the conveyor plate's feed trough. Simultaneously, a vibrator drives the conveyor plate to vibrate. This vibration causes the granules to move towards the outlet end of the feed trough. Upon reaching the outlet end, the vibration of the conveyor plate causes the granules to fall into the guide trough of the guide plate under their own gravity. This process effectively conveys the dry-process lithium battery granules into the guide trough of the guide plate.

[0004] Because dry-process lithium battery granules are sticky, they often clump together when discharged from the outlet. The aforementioned automatic feeding equipment cannot break up or screen the dry-process lithium battery granules discharged from the outlet. Therefore, when the clumped dry-process lithium battery granules enter the gap between the two rolls through the conveying trough, guide trough, and feed trough, the gap is easily blocked, causing the hot rolling forming machine to malfunction.

[0042] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0043] Please refer to Figures 1 to 3 An embodiment of this utility model provides an automatic feeding device, which includes two supports 10 arranged opposite to each other, a hopper mechanism 20, a vibrator 30, a conveyor plate 40, a screening and de-clumping mechanism 50, a preheating mechanism 60 and a smoothing mechanism 70.

[0044] Combination Figures 4 to 7 As shown, the hopper mechanism 20 is located above and connected to the two supports 10. The hopper mechanism 20 is used to pre-store dry lithium battery granules. The top and bottom of the hopper mechanism 20 are respectively provided with an inlet 21 and an outlet 22 that communicate with the interior of the hopper mechanism 20. The operator can put the dry lithium battery granules into the hopper mechanism 20 through the inlet 21, and the dry lithium battery granules can be discharged from the outlet 22.

[0045] Specifically, the hopper mechanism 20 includes a hopper 23 and a partition assembly 24. The partition assembly 24 includes a partition mounting plate 241, a hollow partition housing 242, partition wheels 243, a partition motor 244, and a partition reducer 245.

[0046] Two connecting columns 13 are respectively provided on the inner side of the two supports 10. The two connecting columns 13 are close to the top of the two supports 10. The top of the connecting column 13 is provided with a support column 14. The partition mounting plate 241 is set on the top of the support column 14 and is provided with the discharge port 22. The support column 14 can provide installation support for the partition mounting plate 241. The top of the partition mounting plate 241 is provided with two mounting brackets 2411 arranged opposite each other. The hopper 23 is located between the two mounting brackets 2411 and is connected to the two mounting brackets 2411 respectively. The two mounting brackets 2411 can provide installation support for the hopper 23. In this embodiment, the outer wall of the hopper 23 is provided with two hopper mounting parts 232 arranged opposite each other. The two hopper mounting parts 232 are respectively connected to the top of the two mounting brackets 2411. The top of the hopper 23 is provided with the inlet 21, and the bottom of the hopper 23 is provided with the hopper outlet 231. Both the inlet 21 and the hopper outlet 231 are in communication with the interior of the hopper 23.

[0047] In this embodiment, the separator shell 242 is rectangular. Understandably, the separator shell 242 can also be of other shapes. The bottom end of the separator shell 242 is located at the top end of the separator mounting plate 241. The bottom end of the hopper 23 is inserted into the separator shell 242 from the top end. Both the hopper outlet 231 and the discharge port 22 are connected to the interior of the separator shell 242. The separator wheel 243 is located inside the separator shell 242 and the hopper outlet 231. Both ends of the separator wheel 243 are rotatably connected to both ends of the separator shell 242. Specifically, both ends of the separator shell 242 are provided with mounting holes. Both ends of the separator wheel 243 pass through the mounting holes at both ends of the separator shell 242 and are respectively fitted with two separator bearing seats 2432. The two separator bearing seats 2432 are respectively located at both ends of the separator shell 242. Multiple separator grooves 2431 are spaced circumferentially on the outer circumferential surface of the separator wheel 243. The number of separator grooves 2431 can be set according to actual conditions. A separator reducer 245 is mounted on the top of the separator mounting plate 241. Specifically, a reducer base 2451 is provided on the top of the separator mounting plate 241, and the separator reducer 245 is mounted on the reducer base 2451. A separator motor 244 is mounted on the separator reducer 245, and the output end of the separator motor 244 is connected to the input end of the separator reducer 245. The output end of the separator reducer 245 passes through one of the mounting brackets 2411 and is connected to one end of the separator wheel 243. The separator motor 244 is used to drive the separator wheel 243 to rotate through the separator reducer 245. After the operator feeds dry-process lithium battery granules into the hopper 23 through the inlet 21, the granules move towards the outlet 231 under their own gravity and enter the separator trough 2431. Then, under the rotation of the separator wheel 243, the granules are sequentially conveyed from the separator trough 2431 to the outlet 22, where they are discharged under their own gravity. The separator wheel 243 ensures that the dry-process lithium battery granules in the hopper 23 are conveyed evenly and quantitatively, guaranteeing the stability of the granule discharge.

[0048] In this embodiment, each connecting post 13 has two support pillars 14 at its top, and the two support pillars 14 are spaced apart along the length of the connecting post 13. Understandably, the number of support pillars 14 can be set according to the actual situation.

[0049] A pressure sensor 15 is provided at the top of the support column 14, and a partition mounting plate 241 is disposed at the top of the pressure sensor 15. The pressure sensor 15 is used to detect the pressure applied by the hopper mechanism 20 to the connecting column 13. In practical applications, since the weight of the hopper 23 and the partition assembly 24 of the hopper mechanism 20 remains constant, while the weight of the dry-process lithium battery granules in the hopper 23 is constantly decreasing, by detecting the pressure applied by the hopper mechanism 20 to the connecting column 13, the amount of remaining dry-process lithium battery granules in the hopper 23 can be monitored, thereby facilitating the operator to add dry-process lithium battery granules to the hopper 23.

[0050] The vibrator 30 is disposed between two supports 10. Specifically, multiple crossbeams 11, for example, are provided between the two supports 10, spaced apart. A vibrator mounting plate 12 is provided at the top of each crossbeam 11, and the vibrator 30 is mounted on the top of the vibrator mounting plate 12. A conveyor plate 40 is disposed on top of the vibrator 30, with one end protruding from one side of the two supports 10. A conveying groove 41 is provided at the top of the conveyor plate 40, and the discharge end of the conveying groove 41 extends to one end of the conveyor plate 40. This invention does not modify the structure of the vibrator 30; an existing vibrator 30 can be used. The vibrator 30 is used to drive the conveyor plate 40 to vibrate, so that the dry lithium battery granules entering the feed end of the conveyor trough 41 can move towards the discharge end of the conveyor trough 41. In actual application, one end of the inclined guide plate 102 of the hot rolling forming machine is located below one end of the conveyor plate 40. When the dry lithium battery granules move to the discharge end of the conveyor trough 41, the dry lithium battery granules can fall into the guide groove 1021 of the guide plate 102 under their own gravity. In this way, the dry lithium battery granules can be conveyed into the guide groove 1021. Then, the dry lithium battery granules can enter the material trough 104 of the hot rolling forming machine along the guide groove 1021 (see Figure 13 The material is then placed into the gap between two rollers 103, and then the two rollers 103 rotate in opposite directions, thereby pressing the dry lithium battery granules into electrode films.

[0051] Combination Figures 6 to 10 As shown, the screening and de-clumping mechanism 50 is used to break up and screen the dry-process lithium battery granules discharged from the discharge port 22 to prevent the dry-process lithium battery granules from clumping or forming. This prevents the dry-process lithium battery granules from clogging the roll gap between the two rolls 103 of the hot rolling mill, ensuring the normal operation of the hot rolling mill. The screening and de-clumping mechanism 50 includes a hopper 51, a de-clumping assembly 52, a de-clumping drive assembly 53 for driving the de-clumping assembly 52 to rotate, and a circular screen 54 disposed in the hopper 51.

[0052] The hopper 51 is located between the partition mounting plate 241 and the conveyor plate 40 of the hopper mechanism 20 and is connected to the conveyor plate 40. Specifically, an annular hopper mounting portion 511 is formed on the outer peripheral surface of the hopper 51. Conveyor plate mounting portions 42 are respectively provided on both sides of the conveyor plate 40. Screws 43 are threadedly installed on the conveyor plate mounting portions 42 and the hopper mounting portions 511. In this embodiment, the hopper mounting portion 511 is provided with a first threaded hole, and the conveyor plate mounting portion 42 is provided with a second threaded hole 421 corresponding to the first threaded hole. Screws 43 are threadedly installed in the second threaded hole 421 and the corresponding first threaded hole. When the vibrator 30 drives the conveyor plate 40 to vibrate, the hopper 51 can be driven to vibrate under the action of the screws 43. The screws 43 are threadedly installed on the conveyor plate mounting portion 42 and the hopper mounting portion 43, which facilitates assembly and prevents the hopper mounting portion 511 from disengaging from the screws 43 when the vibrator 30 drives the conveyor plate 40 and the hopper 51 to vibrate, thus ensuring the accuracy of the position of the hopper 51. The top and bottom of the hopper 51 are respectively provided with a hopper inlet 512 and a hopper outlet 513 communicating with the interior of the hopper 51. The hopper inlet 512 corresponds to the discharge port 22. The clogging assembly 52 corresponds to the discharge port 22 and the hopper inlet 512 and is rotatably connected to the bottom end of the partition mounting plate 241 of the hopper mechanism 20. The clogging assembly 52 partially passes through the hopper inlet 512 and extends into the hopper 51, and is close to the screen 54. The feed end of the conveying trough 41 is located below the hopper outlet 513. The vibration of the hopper 51 can drive the screen 54 to vibrate.

[0053] In this embodiment, there are two conveyor plate mounting portions 42 on each side of the conveyor plate 40. It can be understood that the number of conveyor plate mounting portions 42 can be set according to the actual situation.

[0054] In this embodiment, the de-clumping assembly 52 includes a stirring rod 521 and a de-clumping scraper 522. The bottom end of the partition mounting plate 241 of the hopper mechanism 20 is provided with two opposing de-clumping bases 2413, with a de-clumping mounting plate 2412 positioned between the two bases. The mounting plate 2412 is located below the discharge port 22. One end of the stirring rod 521 is rotatably connected to the bottom end of the mounting plate 2412 via a stirring bearing seat 5211. The other end of the stirring rod 521 passes through the hopper inlet 512 and extends into the hopper 51. The de-clumping scraper 522 is sleeved around the outer periphery of the other end of the stirring rod 521. Both the other end of the stirring rod 521 and the de-clumping scraper 522 are close to the screen 54. The length of the de-clumping scraper 522 is slightly smaller than the diameter of the screen 54. The de-clogging drive assembly 53 includes a de-clogging motor 531, a de-clogging reducer 532, and a de-clogging transmission module. The de-clogging reducer 532 is located on one side of the partition mounting plate 241 of the hopper mechanism 20. In actual application, the de-clogging reducer 532 is located on the side of the partition mounting plate 241 of the hopper mechanism 20 away from the hot rolling mill. The de-clogging reducer 532 is connected to the top of the partition mounting plate 241 of the hopper mechanism 20 via a mounting base 5321. The de-clogging motor 531 is mounted on the de-clogging reducer 532, and the output end of the de-clogging motor 531 is connected to the input end of the de-clogging reducer 532. The output end of the de-clogging reducer 532 is connected to the stirring rod 521 via the de-clogging transmission module. The de-clogging motor 531 drives the stirring rod 521 to rotate through the de-clogging reducer 532 and the de-clogging transmission module, thereby driving the de-clogging scraper 522 to rotate. After the dry-process lithium battery granules are discharged from the outlet 22, they can enter the hopper 51 through the hopper inlet 512 under their own gravity and be located on the screen 54. The agitator 521 and the de-clogging scraper 522 are driven to rotate by the de-clogging drive assembly 53. The de-clogging scraper 522 can agitate the dry-process lithium battery granules to break them up. At the same time, under the vibration of the hopper 51 and the screen 54, the broken dry-process lithium battery granules can be screened by the screen 54. After screening, the dry-process lithium battery granules can be discharged from the inside of the hopper 51 and the hopper outlet 513. Then, the dry-process lithium battery granules can fall into the feed end of the conveying trough 41.

[0055] The de-clogging transmission module includes a driving wheel 533, a driven wheel 534, and a synchronous belt (not shown in the figure) sleeved on the outer periphery of the driving wheel 533 and the driven wheel 534. The driving wheel 533 is sleeved on the outer periphery of the output end of the de-clogging reducer 532, and the driven wheel 534 is sleeved on the outer periphery of the stirring rod 521, with part of the driven wheel 534 extending into the stirring bearing seat 5211. The de-clogging motor 531 drives the driving wheel 533 to rotate through the de-clogging reducer 532, and under the transmission action of the driven wheel 534 and the synchronous belt, it can drive the stirring rod 521 to rotate. The de-clogging scraper 522 has a through hole at the middle position, passing through its top and bottom ends, and the de-clogging scraper 522 is sleeved on the outer periphery of the other end of the stirring rod 521 through the through hole.

[0056] Furthermore, the top of the debulking mounting plate 2412 is provided with a V-shaped plate 2414, the V-shaped angle of which extends into the discharge port 22. Two extensions 2415 are formed at each end of the V-shaped plate 2414, respectively. The two inclined surfaces of the V-shaped plate 2414 guide the dry-process lithium battery particles entering the discharge port 22, preventing them from falling onto the top of the debulking mounting plate 2412 and ensuring that the dry-process lithium battery particles can be smoothly discharged from the discharge port 22.

[0057] Furthermore, a receiving plate 56 is provided between the bottom end of the hopper 51 and the conveying plate 40. Two connecting plates 561 are respectively connected to both ends of the receiving plate 56. The end of the connecting plate 561 away from the receiving plate 56 is connected to the hopper mounting part 511. A discharge channel 55 communicating with the hopper outlet 513 is formed between the receiving plate 56 and the bottom end of the hopper 51. The inlet end of the conveying trough 41 is located below the first and second ends of the discharge channel 55. The vibration of the hopper 51 can drive the receiving plate 56 and the two connecting plates 561 to vibrate. The receiving plate 56 and the two connecting plates 561 are integrally formed parts, which are easy to manufacture. The shape of the integral part is an inverted trapezoid, and the shape of the integral part is adapted to the cross-sectional shape of the hopper 51. After being screened, the dry-process lithium battery granules pass through the inside of the hopper 51 and out of the hopper outlet 513. They first enter the discharge channel 55, and then, under the vibration of the receiving plate 56, fall from the first end of the discharge channel 55 into the feed end of the conveying trough 41 under their own gravity. The receiving plate 56 and the two connecting plates 561 serve to receive the dry-process lithium battery granules coming out of the hopper outlet 513, ensuring that the dry-process lithium battery granules can smoothly enter the feed end of the conveying trough 41.

[0058] A baffle plate 562 is provided on the side of the receiving plate 56 and the two connecting plates 561 away from the conveying trough 41. The top of the baffle plate 562 is located between the bottom of the hopper 51 and the receiving plate 56. The baffle plate 562 blocks the dry-process lithium battery particles located in the discharge channel 55, preventing them from coming out from the second end of the discharge channel 55, and ensuring that the dry-process lithium battery particles fall into the inlet end of the conveying trough 41 through the first end of the discharge channel 55. The height of the baffle plate 562 can be set according to the actual situation.

[0059] In this embodiment, a horizontal portion is formed at the end of the connecting plate 561 that is away from the receiving plate 56, and the horizontal portion is connected to the hopper mounting portion 511.

[0060] In this embodiment, the screen 54 is detachably disposed inside the hopper 51 for easy replacement. Specifically, the inner wall of the hopper 51 forms a ring 514, and an annular pressure plate 515 is detachably installed at the top of the ring 514. The edge of the screen 54 is sandwiched between the pressure plate 515 and the ring 514. When actually replacing the screen 54, first remove the pressure plate 515 from the ring 514, then remove the screen 54 from the ring 514, then place the edge of the new screen 54 at the top of the ring 514, and then install the pressure plate 515 at the top of the ring 514.

[0061] In this embodiment, the ring portion 514 is provided with a first mounting hole, and the pressure plate 515 is provided with a second mounting hole corresponding to the first mounting hole. Fasteners such as screws are installed in the second mounting hole and the corresponding first mounting hole. By removing and installing the fasteners, the pressure plate 515 can be disassembled and assembled. The number of the first mounting hole and the second mounting hole can be set according to the actual situation.

[0062] Combination Figure 10 and Figure 11As shown, the conveying trough 41 has a flow channel structure, including a herringbone-shaped primary diversion trough 411. The feed end of the primary diversion trough 411 is located below the hopper outlet 513, and the feed end of the primary diversion trough 411 is located between the first end and the second end of the discharge channel 55. The two discharge ends of the primary diversion trough 411 are respectively connected to the feed ends of two herringbone-shaped secondary diversion troughs 412. The two discharge ends of the secondary diversion troughs 412 are respectively connected to the feed ends of two U-shaped tertiary diversion troughs 413. The two discharge ends of the tertiary diversion troughs 413 extend to one end of the conveying plate 40. After the dry-process lithium battery granules enter the discharge channel 55, under the vibration of the receiving plate 56 and the two connecting plates 561, the dry-process lithium battery granules can fall from the first end of the discharge channel 55 into the inlet end of the primary diversion trough 411. Under the vibration of the conveyor plate 40, the dry-process lithium battery granules can move towards the end closer to the conveyor plate 40. The primary diversion trough 411 can first divert the dry-process lithium battery granules, and then the secondary diversion trough 412 can divert the dry-process lithium battery granules a second time. Finally, the tertiary diversion trough 413 can further divert the dry-process lithium battery granules. The material undergoes a third diversion. Due to the good normal distribution characteristics of dry lithium battery granules, the conveying trough 41 with this structure can achieve uniform conveying of the dry lithium battery granules, so that the dry lithium battery granules entering the material trough 104 of the hot rolling forming machine are uniformly distributed. This ensures that the dry lithium battery granules entering the roll gap between the two rolls 103 are uniform. When the dry lithium battery granules entering the roll gap are rolled into electrode films by the two rolls 103, the consistency of the electrode film thickness can be ensured, thus improving the quality of the electrode film.

[0063] Combination Figure 12As shown, the preheating mechanism 60 is used to preheat the dry-process lithium battery granules, ensuring that the granules have a certain temperature before entering the gap between the two rolls 103. This prevents heat transfer from the rolls 103 to the granules when they enter the gap, thus preventing heat loss and ensuring the quality of the electrode film. Specifically, the preheating mechanism 60 includes a heat lamp 61, such as an infrared lamp. The heat lamp 61 is mounted on the top of the insulation cover 62 via a heat lamp base 611. The insulation cover 62 is mounted on the guide plate 102 of the hot rolling forming machine. Specifically, the insulation cover 62 has an open bottom, with two insulation cover mounting parts 621 formed on both sides of the bottom. The two insulation cover mounting parts 621 are respectively mounted on both sides of the guide plate 102. After the dry-process lithium battery granules fall from the outlet end of the three-stage diversion channel 413 into the guide channel 1021 of the guide plate 102, the dry-process lithium battery granules can move downward along the guide channel 1021 under their own gravity and enter the material trough 104 above the roller gap. When the dry-process lithium battery granules are located in the heat insulation cover 62, the dry-process lithium battery granules can be irradiated by the heat lamp 61, thereby achieving preheating of the dry-process lithium battery granules. The heat insulation cover 62 plays a role in heat preservation of the dry-process lithium battery granules.

[0064] Combination Figure 13 and Figure 14 As shown, the smoothing mechanism 70 is used to smooth the dry-process lithium battery particles located in the feed trough 104, further ensuring that the dry-process lithium battery particles in the feed trough 104 are uniformly distributed. This further ensures that the dry-process lithium battery particles entering the roll gap between the two rollers 103 are uniform, thereby ensuring the consistency of the electrode film thickness and further improving the quality of the electrode film. Specifically, the smoothing mechanism 70 includes a smoothing base plate 71, a linear module 72, a first mounting plate 73, a second mounting plate 74, a smoothing cylinder 75, a smoothing scraper 76, and a laser rangefinder sensor 78.

[0065] A smoothing base plate 71 is mounted on the top of the frame 101 of the hot rolling forming machine (only a part of the frame 101 is shown in the accompanying drawings). A straight module 72 is mounted on the top of the smoothing base plate 71, a first mounting plate 73 is mounted on the top of the straight module 72, one end of a second mounting plate 74 is connected to one end of the first mounting plate 73, and the other end of the second mounting plate 74 extends downward. A smoothing cylinder 75 is mounted on one side of the second mounting plate 74. A smoothing scraper 76 is Z-shaped and is mounted on one side of the smoothing cylinder 75, with a portion of the smoothing scraper 76 protruding from the other end of the second mounting plate 74. In practical applications, the smoothing scraper 76 is located above the material trough 104 and is used to smooth the dry-process lithium battery granules in the material trough 104 of the hot rolling forming machine. A third mounting plate 77 is provided at one end of the second mounting plate 74, and a laser rangefinder 78 is mounted on the side of the third mounting plate 77 away from the second mounting plate 74. The laser rangefinder 78 is used to measure the height of dry-process lithium battery granules in the feed trough 104. The linear module 72 drives the first mounting plate 73 to reciprocate linearly along the length of the roller 103, thereby driving the second mounting plate 74, the leveling cylinder 75, the leveling scraper 76, the third mounting plate 77, and the laser rangefinder 78 to reciprocate linearly along the length of the roller 103. The leveling cylinder 75 drives the leveling scraper 76 to move up and down. In the initial state, the first mounting plate 73, the second mounting plate 74, the leveling cylinder 75, the leveling scraper 76, the third mounting plate 77, and the laser rangefinder 78 are located on one side of the feed trough 104, as shown below. Figure 13 As shown, the smoothing scraper 76 is located above the material trough 104. After the dry-process lithium battery granules enter the material trough 104, the linear module 72 drives the first mounting plate 73, the second mounting plate 74, the smoothing cylinder 75, the smoothing scraper 76, the third mounting plate 77, and the laser rangefinder 78 to move along the length of the roller 103 to the other side of the material trough 104. During this process, the laser rangefinder 78 can measure the height of the dry-process lithium battery granules. When the measured height of the dry-process lithium battery granules in the material trough 104 is uneven, the linear module 72 first drives the first mounting plate 73, the second mounting plate 74, the smoothing cylinder 75, and the smoothing scraper 76 to move along the length of the roller 103 to the other side of the material trough 104. 6. The third mounting plate 77 and the laser rangefinder 78 move along the length of the roller 103, so that the smoothing scraper 76 is located above one end of the material trough 104. Then, the smoothing scraper 76 is driven to move downward by the smoothing cylinder 75, so that the bottom end of the smoothing scraper 76 is located inside one end of the material trough 104. Then, the first mounting plate 73, the second mounting plate 74, the smoothing cylinder 75, the smoothing scraper 76, the third mounting plate 77 and the laser rangefinder 78 are driven along the length of the roller 103 to one side of the material trough 104 by the linear module 72. During this process, the dry lithium battery granules located in the material trough 104 can be smoothed by the smoothing scraper 76.

[0066] In addition, the height of the dry lithium battery granules can be measured by the laser rangefinder 78, and the rotation speed of the separator motor 244 can be adjusted according to the measurement results. This allows for adjustment of the rotation speed of the separator wheel 243, which in turn adjusts the speed at which the dry lithium battery granules are discharged from the outlet 22. This helps to regulate the amount of dry lithium battery granules entering the trough 104, preventing the amount of dry lithium battery granules in the trough 104 from being too much or too little.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
