Description

Technical Field

[0001] This invention belongs to the field of lithium cobalt oxide production technology, and particularly relates to a quantitative filling device for lithium cobalt oxide production materials. Background Technology

[0002] The preparation of positive electrode materials for lithium-ion batteries mainly involves mixing and grinding cobalt, nickel, manganese, iron phosphate oxides, and lithium salts, followed by sintering and processing. The material that has not undergone high-temperature sintering is a powdery mixture with a fineness at the micron level, and the container used to hold this mixture is a mullite sagger.

[0003] The Chinese patent CN219904798U, "Metering and Packing Device for Lithium-ion Battery Cathode Materials," describes a device comprising a frame, a conveying mechanism, a crate lifting mechanism, and a feeding mechanism. The conveying mechanism transports crates to the packing station; the crate lifting mechanism elevates the crates located at the packing station; and the feeding mechanism includes a metering hopper, a buffer hopper, and a feeding hopper connected sequentially from top to bottom. A feeding valve connects the metering hopper and the buffer hopper. The buffer hopper has two independent storage spaces, each with an inlet and an outlet at its upper and lower ends, respectively. An inlet valve is installed at the inlet, and an outlet valve at the outlet. The inlet of each storage space is connected to the metering hopper, and the outlet of each storage space is connected to the feeding hopper. This invention stores crates in the buffer hopper via the metering hopper, ensuring the amount of crates packed. Furthermore, the two storage spaces of the buffer hopper facilitate switching between metering buffering and crating, improving packing efficiency.

[0004] Currently, to optimize the efficiency of the filling device, the inventors have found that the current process focuses on weighing materials one by one using a precise reduction method and cleverly storing them temporarily in the storage space. However, this operation mode, which only allows one weighing at a time, inevitably limits the speed and efficiency of the overall workflow. Therefore, exploring a more efficient and continuous material handling solution to reduce the number of weighings and accelerate material flow will be key to optimizing the filling device's workflow.

[0005] Therefore, based on the above problems, we designed a quantitative filling device for lithium cobalt oxide production materials. Summary of the Invention

[0006] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a quantitative filling device for lithium cobalt oxide production materials. This device solves the technical problem that the existing filling devices, which only allow single weighing at a time, inevitably limit the speed and efficiency of the overall operation process.

[0007] To achieve the above objectives, an embodiment of the first aspect of the present invention provides a quantitative filling device for lithium cobalt oxide production materials, comprising a frame, a hopper disposed on the frame, an inner cavity disposed within the hopper, and a feed inlet disposed on the side of the hopper;

[0008] Also includes:

[0009] The storage cylinder is rotatably installed inside the cavity. A discharge port is provided on one side of the bottom surface of the storage cylinder. An annular groove is provided on the inner wall of the bottom surface of the cavity. A discharge port for discharging material is provided through the annular groove.

[0010] A cylindrical metering bin is located at the bottom of the discharge port of the silo. A metering rotating column is rotatably installed inside the cylindrical metering bin, and several metering grooves are arranged in a circular pattern at equal intervals on the metering rotating column.

[0011] A further improvement is that it also includes a striking assembly, which includes a swing lever rotatably mounted on the outer wall of the hopper, tracks respectively mounted vertically on the hopper, striking rods rotatably mounted at both ends of the swing lever and passing through the hopper, and guide wheels rotatably mounted at the ends of the striking rods. Each track is provided with a compression spring, and each striking rod passes through and is inserted into the track. The compression spring is movably sleeved on the striking rod, and the end of the compression spring is connected to the striking rod.

[0012] A further improvement is that a base is connected to the side of the hopper, and a large wheel and a small wheel connected by a belt are rotatably arranged on the top surface of the hopper and the base, respectively. An eccentric wheel connected to the small wheel is rotatably arranged on the bottom surface of the base.

[0013] A further improvement is that the outer wall of the eccentric wheel is provided with several equally spaced protrusions, and the large rotating wheel is driven by a servo motor externally mounted on the top surface of the hopper, with the main shaft of the servo motor connected to the large rotating wheel.

[0014] A further improvement is that the top and bottom surfaces of the cylindrical quantitative bin are provided with guide ports, and a stepper motor connected to the main shaft and the quantitative rotating column is provided on the outside of the cylindrical quantitative bin.

[0015] A further improvement is that it also includes a lifting loading platform, which is set inside the frame port and below the material hopper discharge port. The lifting loading platform is equipped with a U-shaped enclosure, and a vibration table is set inside the U-shaped enclosure. The vibration table includes a base plate connected inside the U-shaped enclosure, a vibration seat set on the base plate, a vibrator set on the bottom surface of the vibration seat, and a set of springs set between the vibration seat and the base plate.

[0016] A further improvement is that a hydraulic lifting cylinder is installed inside the frame, the rod of the hydraulic lifting cylinder is connected to the bottom surface of the lifting loading platform, and sliding grooves are provided on both inner walls of the frame, with the sides of the lifting loading platform slidably disposed in the sliding grooves.

[0017] A further improvement is that the vibration seat has sagger grooves at the four corners of its surface, and rubber angle steel brackets are connected to the inner walls of the four corners of the sagger grooves. Suction cups are provided on the inner walls of the bottom surface at the four corners.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) When the servo motor drives the large rotating wheel and the inner storage cylinder to rotate, the small rotating wheel and the eccentric wheel are also linked by the tight synchronous transmission of the belt. Whenever the protrusion on the eccentric wheel meets the top of the swing lever, the protrusion applies pressure to the upper end of the swing lever and the connected upper striking rod, pushing it to move smoothly within the preset track until the guide wheel at its end contacts the upper outer wall of the inner storage cylinder, while compressing the built-in compression spring to store energy. Once the protrusion separates from the swing lever, the compression spring immediately releases the stored rebound force, quickly pulling the upper striking rod back to the initial position, and also drives the lower end of the swing lever and the lower striking rod through the leverage effect, so that the guide wheel at its end strikes the lower outer wall of the inner storage cylinder. This process is repeated, which can effectively knock and vibrate the material in the inner storage cylinder, effectively prevent the material from adhering to the cylinder wall of the inner storage cylinder, and eliminate the risk of blockage, thereby significantly improving the output rate of production materials and the overall production efficiency.

[0020] (2) This invention uses a stepper motor to precisely drive the quantitative rotating column to rotate within the cylindrical quantitative bin. This action ensures that each quantitative slot is sequentially and accurately aligned with the discharge port of the upper bin. Subsequently, the material smoothly falls into the pre-positioned quantitative slot. As the quantitative rotating column continues to rotate, whenever a fully loaded quantitative slot rotates to a position directly corresponding to the lower guide port, the material in the slot is accurately released from the lower guide port. This design eliminates the cumbersome single weighing steps, greatly improving the continuity, speed, and efficiency of the overall operation process;

[0021] (3) This invention uses pre-placed rubber angle steel brackets in the crucible slots. When the crucible is precisely embedded in these four elastic angle steel brackets, the four suction cups ensure the crucible is firmly in place, greatly facilitating the easy extraction and operation of the fully loaded crucible. As the material flows out from the bottom feed port of the cylindrical quantitative hopper and falls precisely into the waiting crucible, the built-in motor of the vibrator drives the eccentric oscillator to generate high-frequency micro-amplitude vibration, ensuring that the material in the crucible is uniform and flat, thus laying the foundation for subsequent processing or storage and further improving production efficiency.

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, a quantitative filling device for lithium cobalt oxide production materials includes a frame 1, a hopper 2 disposed on the frame 1, an inner cavity 22 disposed in the hopper 2, and a feed inlet 21 disposed on the side of the hopper 2.

[0035] like Figure 2 and Figure 5As shown, the implementation includes: a storage inner cylinder 4, which is rotatably disposed in the inner cavity 22. A discharge port 41 is provided on one side of the bottom surface of the storage inner cylinder 4. An annular groove 42 is provided on the inner wall of the bottom surface of the inner cavity 22. A discharge port 43 for discharging material is provided through the annular groove 42. The inner wall of the bottom surface of the storage inner cylinder 4 is inclined. Before implementation, an inlet 21 is provided on the side of the storage inner cylinder 4 for introducing production materials.

[0036] like Figure 1 and Figure 2 As shown, the implementation includes: a striking assembly 3, which includes a swing lever 36 rotatably mounted on the outer wall of the hopper 2, rails 37 respectively mounted vertically on the hopper 2, striking rods 34 rotatably mounted at both ends of the swing lever 36 and passing through the hopper 2, and guide wheels 341 rotatably mounted at the ends of the striking rods 34. Each rail 37 is provided with a compression spring 371, and each striking rod 34 passes through and is inserted into the rail 37. The compression spring 371 is movably sleeved on the striking rod 34, and the end of the compression spring 371 is connected to the striking rod 34.

[0037] Specifically, a base 33 is connected to the side of the hopper 2. A large rotating wheel 31 and a small rotating wheel 32, connected by a belt, are rotatably mounted on the top surface of the hopper 2 and the base 33, respectively. An eccentric wheel 35, connected to the small rotating wheel 32, is rotatably mounted on the bottom surface of the base 33. Several equally spaced protrusions are provided on the outer wall of the eccentric wheel 35. The large rotating wheel 31 is driven by a servo motor externally mounted on the top surface of the hopper 2. The main shaft of the servo motor is connected to the large rotating wheel 31. As the large rotating wheel 31 rotates, the small rotating wheel 32 and the eccentric wheel 35 are also linked through the tight synchronous transmission of the belt. Whenever the protrusion on the eccentric wheel 35 meets the top of the swing lever 36, the protrusion applies pressure to the upper end of the swing lever 36 and the connected upper striking rod 34, pushing it to move smoothly within the preset track 37 until the guide wheel 341 at its end contacts the upper outer wall of the storage cylinder 4, while compressing the built-in compression spring 371 to store energy. Once the protrusion separates from the swing lever 36, the compression spring 371 immediately releases the accumulated rebound force, quickly pulling the upper striking rod 34 back to its initial position. It also drives the lower end of the swing lever 36 and the lower striking rod 34 through a lever effect, causing the guide wheel 341 at its end to strike the lower outer wall of the storage inner cylinder 4. This process repeats continuously, effectively vibrating the material inside the storage inner cylinder 4, effectively preventing material from adhering to the cylinder wall and eliminating the risk of blockage, thereby significantly improving the material discharge rate and overall production efficiency.

[0038] like Figure 2 and Figure 3 As shown, the implementation also includes: a cylindrical quantitative bin 5, which is set at the bottom of the discharge port of the bin 2. A quantitative rotating column 51 is rotatably arranged inside the cylindrical quantitative bin 5, and several quantitative grooves 52 are arranged in a circular pattern at equal intervals on the quantitative rotating column 51.

[0039] Specifically, the top and bottom surfaces of the cylindrical metering bin 5 are equipped with guide ports 53. A stepper motor connected to the main shaft and metering rotating column 51 is installed outside the cylindrical metering bin 5. The stepper motor precisely drives the metering rotating column 51 to rotate within the cylindrical metering bin 5. This action ensures that each metering slot 52 is sequentially and accurately aligned with the discharge port of the upper hopper 2. Subsequently, the material smoothly falls into the pre-positioned metering slot 52. As the metering rotating column 51 continues to rotate, whenever a fully loaded metering slot 52 rotates to a position directly corresponding to the lower guide port 53, the material in the slot is accurately released from the lower guide port 53.

[0040] like Figure 4 As shown, this embodiment also includes: a lifting loading platform 11, which is set inside the port of the frame 1 and below the discharge port of the hopper 2. A U-shaped enclosure 13 is set on the lifting loading platform 11, and a vibrating table 14 is set inside the U-shaped enclosure 13. The vibrating table 14 includes a base plate 141 connected inside the U-shaped enclosure 13, a vibrating seat 142 set on the base plate 141, a vibrator 143 set on the bottom surface of the vibrating seat 142, and a set of springs 144 set between the vibrating seat 142 and the base plate 141. By starting the motor built into the vibrator 143, the eccentric oscillator is driven to generate high-frequency micro-amplitude vibration, ensuring that the material in the sagger is uniform and flat, thus laying the foundation for subsequent processing or storage and further improving production efficiency.

[0041] Specifically, a hydraulic lifting cylinder 15 is installed inside the frame 1. The rod of the hydraulic lifting cylinder 15 is connected to the bottom surface of the lifting loading platform 11. Slide grooves 12 are provided on both inner walls of the frame 1. The sides of the lifting loading platform 11 are slidably installed in the slide grooves 12.

[0042] Additionally, a crucible groove 145 is provided at the four corners of the surface of the vibrating seat 142. Rubber angle steel brackets 146 are connected to the inner walls of the four corners of the crucible groove 145, and suction cups 147 are provided on the inner walls of the bottom surface of the four corners. When the crucible is accurately embedded in these four elastic angle steel brackets, the suction of the four suction cups 147 can ensure that the crucible is firmly in place, thereby greatly facilitating the easy extraction and operation of the fully loaded crucible.

[0043] like Figures 1 to 5 As shown, in the implementation of this embodiment, it should also be noted that the servo motor and vibrator 143 in the application documents are commercially available products of the prior art, and their working principles have been disclosed. Before implementation, the speed of the servo motor and the vibration frequency of the vibrator 143 are set. The production material of this application is a powdered mixture.

[0044] Additionally, it should be noted that this application only addresses the shortcomings of existing filling devices that only allow single weighing at a time, inevitably limiting the speed and efficiency of the overall operation process, and does not cover other aspects. The working principle of this quantitative filling device for lithium cobalt oxide production materials is described below:

[0045] During installation and use, on-site staff will guide the material into the storage cylinder 4 through the inlet 21. Then, by starting the servo motor, the large rotating wheel 31 and the storage cylinder 4 will rotate, causing the outlet 41 of the storage cylinder 4 to rotate in the annular groove 23. Whenever the outlet 41 of the storage cylinder 4 is aligned with the outlet 43, the material will fall into the discharge port of the hopper 2 through the outlet 43.

[0046] As the large rotating wheel 31 rotates, the small rotating wheel 32 and the eccentric wheel 35 are also driven in tandem through the tight synchronous transmission of the belt. Whenever the protrusion on the eccentric wheel 35 meets the upper part of the swing lever 36, the protrusion applies pressure to the upper end of the swing lever 36 and the connected upper striking rod 34, pushing it to move smoothly within the preset track 37 until the guide wheel 341 at its end contacts the upper outer wall of the storage cylinder 4, while compressing the built-in compression spring 371 to store energy. Once the protrusion separates from the swing lever 36, the compression spring 371 immediately releases the stored rebound force, quickly pulling the upper striking rod 34 back to its initial position, and also driving the lower end of the swing lever 36 and the lower striking rod 34 through the leverage effect, causing the guide wheel 341 at its end to strike the lower outer wall of the storage cylinder 4. This process is repeated, which can effectively knock and vibrate the material in the inner cylinder 4, effectively prevent the material from adhering to the cylinder wall of the inner cylinder 4, and eliminate the risk of blockage, thereby significantly improving the discharge rate of production materials and overall production efficiency.

[0047] Once the material reaches the bottom feed port 53 of the cylindrical metering hopper 5, a stepper motor precisely drives the metering rotating column 51 to rotate inside the cylindrical metering hopper 5. This action ensures that each metering slot 52 is sequentially and accurately aligned with the discharge port of the upper hopper 2. Subsequently, the material smoothly falls into the pre-positioned metering slot 52. As the metering rotating column 51 continues to rotate, whenever a fully loaded metering slot 52 rotates to a position directly corresponding to the lower feed port 53, the material in the slot is accurately released from the lower feed port 53. This design eliminates the cumbersome single weighing steps, greatly improving the continuity, speed, and efficiency of the overall operation process.

[0048] By pre-positioning rubber angle steel brackets 146 within the crucible slots 145, the crucible is precisely embedded in these four elastic angle steel brackets. The suction cups 147 ensure the crucible's stable positioning, greatly facilitating subsequent easy extraction and operation of the fully loaded crucible. The hydraulic lifting cylinder 15 drives the lifting loading platform 11. As material flows from the bottom guide port 53 of the cylindrical quantitative hopper 5, it precisely falls into the waiting crucible. The vibrator 143's built-in motor drives the eccentric vibrator to generate high-frequency, low-amplitude vibrations, ensuring the material inside the crucible is uniformly and evenly distributed. This lays the foundation for subsequent processing or storage, further improving production efficiency.

[0049] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
