Description

Technical Field

[0001] The invention belongs to the technical field of lithium cobalt oxide production, and in particular relates to a quantitative filling device for lithium cobalt oxide production materials. Background Art

[0002] The preparation of positive electrode materials for lithium-ion batteries is mainly through mixing and grinding cobalt, nickel, manganese, iron phosphate oxide and lithium salt, and then sintering and processing. The material that has not been sintered at high temperature is a powdery mixture with a fineness of micron level, and the tool used to hold this mixture is a mullite sagger.

[0003] The Chinese authorized patent number is CN219904798U, a lithium battery positive electrode material metering and loading device, which includes a frame, a conveying mechanism, a bowl lifting mechanism and a material unloading mechanism.

However, this operation mode that only allows a single weighing each time inevitably limits the speed and efficiency of the overall operation process. Therefore, exploring more efficient and continuous material processing solutions to reduce the number of weighing times and speed up the flow of materials will be the key to optimizing the workflow of the bowl loading device.

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

[0010] The cylindrical quantitative bin is arranged at the bottom of the discharge port of the bin, and a quantitative rotating column is rotatably arranged in the cylindrical quantitative bin, and a plurality of quantitative grooves which are equidistantly distributed in a circle are arranged on the quantitative rotating column.

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

[0012] A further improvement is that the side of the silo is connected to a base, the top surface of the silo and the base are respectively rotatably provided with a large wheel and a small wheel connected by a belt, and the bottom surface of the base is rotatably provided with an eccentric wheel connected to the small wheel.

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

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

[0015] A further improvement is that it also includes a lifting loading platform, which is arranged in the port of the frame and below the discharge port of the silo, and the lifting loading platform is provided with a U-shaped enclosure, and a vibration table is provided in the U-shaped enclosure. The vibration table includes a bottom plate connected to the U-shaped enclosure, a vibration seat arranged on the bottom plate, a vibrator arranged on the bottom surface of the vibration seat, and a group of springs arranged between the vibration seat and the bottom plate.

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

[0017] A further improvement is that sagger grooves are opened at the four corners of the surface of the vibration seat, the inner walls at the four corners of the sagger grooves are connected to rubber angle steel holders, and the inner walls of the bottom surfaces at the four corners are provided with suction cups.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention starts the servo motor to drive the large rotating wheel and the storage inner cylinder to rotate, and utilizes the close synchronous transmission of the belt, so that the small rotating wheel and the eccentric wheel are also linked. Whenever the protrusion on the eccentric wheel meets the upper part of the swing lever, the protrusion applies pressure to the upper end of the swing lever and the connected upper knocking rod, pushing it to move smoothly in the preset track until the guide wheel at its end contacts the upper outer wall of the storage inner cylinder, and at the same time compresses the built-in compression spring to store energy. Once the protrusion is separated from the swing lever, the compression spring immediately releases the accumulated rebound force, quickly pulling the upper knocking rod back to the initial position, and also drives the lower end of the swing lever and the lower knocking rod through the lever effect, so that the guide wheel at its end knocks the lower outer wall of the storage inner cylinder. This process is repeated, which can implement effective knocking vibration on the material in the storage inner cylinder, effectively prevent the material from adhering to the cylinder wall of the storage inner cylinder, and eliminate the risk of blockage, thereby significantly improving the discharge rate of production materials and the overall production efficiency;

[0020] (2) The present invention uses a stepper motor to precisely drive the quantitative rotating column to rotate in the cylindrical quantitative bin. This action ensures that each quantitative slot can be aligned sequentially and accurately with the discharge port of the upper bin. Then, the material falls smoothly into the pre-positioned quantitative slot. As the quantitative rotating column continues to rotate, every time the quantitative slot full of material rotates to a position directly corresponding to the lower material guide port, the material in the slot will be accurately released from the lower material guide port. This design abandons the cumbersome single weighing steps and greatly improves the consistency, speed and efficiency of the overall operation process;

[0021] (3) The present invention pre-places the rubber angle steel holder in the sagger groove. When the sagger is accurately embedded in the four elastic angle steel holders, the four suction cups can be used to ensure that the sagger is firmly in place, thereby greatly facilitating the subsequent easy extraction and operation of the fully loaded sagger. As the material flows out from the material guide port at the bottom of the cylindrical quantitative bin and accurately falls into the waiting sagger, the built-in motor of the vibrator is started to drive the eccentric vibrator to generate high-frequency micro-amplitude vibration, ensuring that the material in the sagger is uniform and flat, thereby laying a 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 in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, a quantitative loading device for lithium cobalt oxide production materials comprises a frame 1, a silo 2 arranged on the frame 1, an inner cavity 22 arranged in the silo 2, and a material inlet 21 arranged on the side of the silo 2;

[0035] like Figure 2 and Figure 5As shown, when implemented, it includes: a material storage inner cylinder 4, which is rotatably arranged in the inner cavity 22, a discharge port 1 41 is arranged on one side of the bottom surface of the material storage inner cylinder 4, an annular groove 42 is arranged on the inner wall of the bottom surface of the inner cavity 22, and a discharge port 2 43 for cooperating with the discharge is arranged through the annular groove 42, and the inner wall of the bottom surface of the material storage inner cylinder 4 is inclined. Before implementation, a feed port 21 is pre-arranged on the side of the material storage inner cylinder 4 for cooperating with the introduction of production materials;

[0036] like Figure 1 and Figure 2 As shown, when implemented, it includes: a knocking assembly 3, which includes a swing lever 36 rotatably arranged on the outer wall of the silo 2, tracks 37 respectively arranged on the upper and lower sides of the silo 2, knocking rods 34 rotatably arranged at both ends of the swing lever 36 and respectively passing through the silo 2, and a guide wheel 341 rotatably arranged at the end of the knocking rod 34, each track 37 is provided with a compression spring 371, each knocking rod 34 is inserted into the track 37, the compression spring 371 is movably sleeved on the knocking rod 34, and the end of the compression spring 371 is connected to the knocking rod 34;

[0037] Specifically, the side of the silo 2 is connected with a base 33, and the top surface of the silo 2 and the base 33 are respectively provided with a large rotating wheel 31 and a small rotating wheel 32 connected by a belt, and the bottom surface of the base 33 is provided with an eccentric wheel 35 connected to the small rotating wheel 32; the outer wall surface of the eccentric wheel 35 is provided with several equidistantly distributed protrusions, and the large rotating wheel 31 is driven by a servo motor externally arranged on the top surface of the silo 2, and the main shaft of the servo motor is connected to the large rotating wheel 31. With the rotation of the large rotating wheel 31, the small rotating wheel 32 and the eccentric wheel 35 are also linked by 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 upper knocking rod 34 connected thereto, pushing it to move smoothly in the preset track 37 until the guide wheel 341 at its end contacts the outer wall of the upper end of the storage inner tube 4, and at the same time compresses the built-in compression spring 371 to store energy. Once the protrusion is separated from the swing lever 36, the compression spring 371 immediately releases the accumulated resilience, quickly pulling the upper knocking rod 34 back to the initial position, and also drives the lower end of the swing lever 36 and the lower knocking rod 34 through the lever effect, so that the guide wheel 341 at its end knocks the lower end outer wall of the storage inner tube 4. This process is repeated repeatedly, which can effectively knock and vibrate the material in the storage inner tube 4, effectively prevent the material from adhering to the wall of the storage inner tube 4, and eliminate the risk of blockage, thereby significantly improving the discharge rate of production materials and the overall production efficiency;

[0038] like Figure 2 and Figure 3 As shown, the implementation also includes: a cylindrical quantitative bin 5, which is arranged at the bottom of the discharge port of the bin 2, and a quantitative rotating column 51 is rotatably arranged in the cylindrical quantitative bin 5, and a plurality of quantitative grooves 52 equidistantly distributed in a circular shape are arranged on the quantitative rotating column 51;

[0039] Specifically, the top and bottom surfaces of the cylindrical quantitative bin 5 are both provided with a material guide port 53, and the outside of the cylindrical quantitative bin 5 is provided with a stepper motor whose main shaft is connected to the quantitative rotating column 51. The stepper motor accurately drives the quantitative rotating column 51 to rotate in the cylindrical quantitative bin 5. This action can ensure that each quantitative slot 52 can be aligned with the discharge port of the upper bin 2 in sequence and accurately. Subsequently, the material falls smoothly into the pre-positioned quantitative slot 52. With the continuous rotation of the quantitative rotating column 51, whenever the quantitative slot 52 full of material rotates to a position directly corresponding to the lower material guide port 53, the material in the slot will be accurately released from the lower material guide port 53;

[0040] like Figure 4 As shown, the present embodiment further includes: a lifting loading platform 11, which is arranged in the port of the frame 1 and is located below the discharge port of the silo 2, a U-shaped enclosure 13 is arranged on the lifting loading platform 11, and a vibration platform 14 is arranged in the U-shaped enclosure 13, and the vibration platform 14 includes a bottom plate 141 connected to the U-shaped enclosure 13, a vibration seat 142 arranged on the bottom plate 141, a vibrator 143 arranged on the bottom surface of the vibration seat 142, and a group of springs 144 arranged between the vibration seat 142 and the bottom plate 141. By starting the built-in motor of the vibrator 143 to drive the eccentric vibrator to generate high-frequency and slight vibration, it is ensured that the material in the sagger is uniform and flat, thereby laying a foundation for subsequent processing or storage, and further improving production efficiency;

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

[0042] In addition, sagger grooves 145 are provided at the four corners of the surface of the vibration seat 142. The inner walls at the four corners of the sagger groove 145 are connected with rubber angle steel holders 146. The inner walls of the bottom surfaces at the four corners are provided with suction cups 147. When the sagger is accurately embedded in the four elastic angle steel holders, the four suction cups 147 are used to absorb and secure the sagger in place, thereby greatly facilitating the subsequent easy extraction and operation of the fully loaded sagger.

[0043] like Figures 1 to 5 As shown, in the implementation of this embodiment, it is also necessary to explain that the servo motor and vibrator 143 in the application document are commercially available products of the prior art, and the working principle has been disclosed. The speed of the servo motor and the vibration frequency of the vibrator 143 are set before implementation. The production material of this application is a powdered mixture;

[0044] In addition, it should be noted that the application document only improves the shortcomings of the existing loading device that only allows a single weighing operation mode each time, which inevitably limits the speed and efficiency of the overall operation process, and does not involve other aspects; the working principle of the quantitative loading device for lithium cobalt oxide production materials is introduced as follows:

[0045] During installation and use, the on-site staff introduces the material into the storage inner cylinder 4 from the material inlet 21, and then starts the servo motor to drive the large rotating wheel 31 and the storage inner cylinder 4 to rotate, so that the discharge port 1 41 of the storage inner cylinder 4 rotates in the annular groove 23. Whenever the discharge port 1 41 of the storage inner cylinder 4 is aligned with the discharge port 2 43, the material passes through the discharge port 2 43 and falls into the discharge port of the silo 2;

[0046] As the large wheel 31 rotates, the small wheel 32 and the eccentric wheel 35 are also linked by the close synchronous transmission of the belt. Whenever the projection on the eccentric wheel 35 meets the upper part of the swing lever 36, the projection applies pressure to the upper end of the swing lever 36 and the upper knocking rod 34 connected thereto, pushing it to move smoothly in the preset track 37 until the guide wheel 341 at its end contacts the upper outer wall of the material storage inner cylinder 4, and compresses the built-in compression spring 371 to store energy. Once the projection separates from the swing lever 36, the compression spring 371 immediately releases the accumulated resilience, quickly pulling the upper knocking rod 34 back to the initial position, and also drives the lower end of the swing lever 36 and the lower knocking rod 34 through the lever effect, so that the guide wheel 341 at its end knocks the lower outer wall of the material storage inner cylinder 4. This process is repeated repeatedly, which can effectively knock and vibrate the materials in the storage inner cylinder 4, effectively prevent the materials from adhering to the cylinder wall of the storage inner cylinder 4, and eliminate the risk of blockage, thereby significantly improving the discharge rate of production materials and the overall production efficiency;

[0047] Once the material reaches the bottom guide port 53 of the cylindrical quantitative bin 5, the stepper motor will accurately drive the quantitative rotating column 51 to rotate in the cylindrical quantitative bin 5. This action can ensure that each quantitative slot 52 can be aligned with the discharge port of the upper bin 2 in sequence and accurately. Then, the material falls smoothly into the pre-positioned quantitative slot 52. As the quantitative rotating column 51 continues to rotate, every time the quantitative slot 52 full of material rotates to a position directly corresponding to the lower guide port 53, the material in the slot will be accurately released from the lower guide port 53. This design abandons the cumbersome single weighing steps and greatly improves the consistency, speed and efficiency of the overall operation process;

[0048] By pre-setting the rubber angle steel holder 146 in the sagger groove 145, when the sagger is accurately embedded in the four elastic angle steel holders, the four suction cups 147 can be used to ensure that the sagger is firmly in place, thereby greatly facilitating the subsequent easy extraction and operation of the fully loaded sagger. By starting the hydraulic lifting cylinder 15 to drive the lifting loading platform 11, as the material flows out from the guide port 53 at the bottom of the cylindrical quantitative bin 5 and accurately falls into the waiting sagger, the motor built into the vibrator 143 is started to drive the eccentric vibrator to generate high-frequency micro-amplitude vibration, ensuring that the material in the sagger is uniform and flat, thereby laying a foundation for subsequent processing or storage, and further improving production efficiency.

[0049] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
