Description

Technical Field

[0001] This utility model relates to the field of protection technology for lithium-ion battery production equipment, and in particular to a raw material stirring device for lithium-ion battery production. Background Technology

[0002] Lithium-ion batteries are a type of rechargeable battery that relies on the intercalation and deintercalation of lithium ions between the positive and negative electrodes to achieve the mutual conversion of electrical energy and chemical energy. They have advantages such as high energy density and are widely used in many fields.

[0003] In the production of lithium-ion batteries, the raw materials need to be stirred to ensure that the active materials, conductive agents, binders and other components are mixed evenly, so that the electrode materials produced have consistent performance and improve the overall performance of the battery. The raw material stirring device used in lithium-ion battery production uses mechanical stirring structures, such as multi-layer blades and variable frequency speed control motors, to mix and disperse the raw materials, thereby meeting the requirements of different raw material characteristics and stirring processes, and ensuring the quality of battery production.

[0004] However, existing raw material mixing devices for lithium-ion battery production have the following shortcomings:

[0005] In the existing technology, the raw material stirring device for lithium-ion battery production is usually simple in structure and the stirring mechanism is relatively simple. Generally, when stirring, the stirring rod rotates in the same direction. This method is prone to uneven mixing, resulting in uneven distribution of the components of the electrode material and insufficient dispersion of active materials, conductive agents, etc.

[0006] Therefore, we propose a raw material stirring device for lithium-ion battery production to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a raw material stirring device for lithium-ion battery production. By using a motor drive combined with gear transmission, the stirring tank can be rotated. At the same time, with the help of another motor drive and transmission of the stirring components, the six stirring rods rotate in opposite directions, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a raw material stirring device for lithium-ion battery production, comprising a frame, a fixed bracket fixedly connected to the top of the frame, a first bearing fixedly inserted into the inner wall of the fixed bracket, a support column fixedly inserted into the inside of the first bearing, a first gear fixedly sleeved on the outer wall of the support column, a second gear meshing with the outer wall of the first gear, a first protective box fixedly connected to the inner wall of the fixed bracket, a rotary motor fixedly connected to the inner wall of the first protective box, and the output end of the rotary motor fixedly inserted into the inside of the second gear, a rotating disk fixedly connected to the top of the support column, a stirring tank placed on the top of the rotating disk, a support rod fixedly connected to the top of the frame, a telescopic frame movably inserted into the inner wall of the support rod, two connecting plates fixedly connected to the outer wall of the telescopic frame, and a protective cover fixedly connected between the bottoms of the two connecting plates.

[0009] Preferably, three second bearings are fixedly inserted into the inner surface of the protective cover, and stirring shafts are fixedly inserted into the interior of two of the three second bearings. A set of fixing rings is fixedly sleeved on the outer surface of the two stirring shafts. Three stirring rods are fixedly connected to the outer surface of the two sets of fixing rings. A rotating shaft is fixedly inserted into the interior of one of the three second bearings, and a third gear is fixedly sleeved on the outer surface of the two stirring shafts and the rotating shaft.

[0010] Preferably, a second protective box is fixedly connected to the top of the telescopic frame, a stirring motor is fixedly connected to the inner wall of the second protective box, and the output end of the stirring motor is fixedly connected to the top of the rotating shaft. A hydraulic rod is fixedly connected to the top of the frame, and the bottom of the telescopic frame is fixedly connected to the telescopic end of the hydraulic rod.

[0011] Preferably, a third protective box is fixedly connected to the top of the protective cover, and two fixing plates are fixedly connected to the top of the rotating disk. A threaded groove is opened on one side of the outer wall of each of the two fixing plates, and a fastening screw is threadedly connected to the inner surface of each of the two threaded grooves.

[0012] Preferably, a knob is fixedly connected to one side of the outer wall of each of the two fastening screws, and a third bearing is fixedly sleeved on the outer wall of each of the two fastening screws.

[0013] Preferably, clamping blocks are fixedly fitted on the outer walls of both third bearings, and a set of guide rods are fixedly connected to one side of the outer wall of each of the two clamping blocks, with the two sets of guide rods movably inserted inside the two fixed plates.

[0014] Preferably, the top of the rotating disk has two sliding grooves, and the inner surface of each of the two sliding grooves is slidably embedded with a slider, and the bottom of the two clamping blocks is fixedly connected to the top of the two sliders.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the interaction of the various components of the device, the rotation of the mixing tank can be achieved by the transmission of the motor drive combined with the gear set. At the same time, with the help of another motor drive and the transmission of the mixing component, the six sets of stirring rods rotate in opposite directions. In this way, the six sets of stirring rods first perform strong shearing and high-speed tumbling on the raw materials, breaking the agglomeration of the raw materials and initially mixing them. Subsequently, the counter-rotating mixing tank imparts shearing force and turbulence to the raw materials in different directions, causing the materials to continuously roll and convect in a multi-dimensional flow field, further improving the mixing uniformity, ensuring that the lithium-ion battery raw materials are fully mixed, achieving uniform distribution of the various components of the electrode material, and enabling key components such as active materials and conductive agents to be fully dispersed.

[0017] 2. In this utility model, the mixing tank can be stably clamped by the interaction of the various components of the device. During the rotation of the mixing tank, this clamping method can effectively resist the influence of external forces such as centrifugal force, so as to maintain a precise and stable position, significantly improve the stability and reliability of the mixing operation, and provide a strong guarantee for the uniform and high-quality mixing of lithium-ion battery raw materials.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: a raw material stirring device for lithium-ion battery production, including a frame 1, a fixed frame 2 fixedly connected to the top of the frame 1, a first bearing 3 fixedly inserted into the inner wall of the fixed frame 2, a support column 4 fixedly inserted into the inside of the first bearing 3, a first gear 5 fixedly sleeved on the outer wall of the support column 4, a second gear 6 meshing with the outer wall of the first gear 5, a first protective box 7 fixedly connected to the inner wall of the fixed frame 2, a rotary motor 8 fixedly connected to the inner wall of the first protective box 7, and the output end of the rotary motor 8 fixedly inserted into the inside of the second gear 6, a rotating disk 9 fixedly connected to the top of the support column 4, a stirring tank 10 placed on the top of the rotating disk 9, a support rod 11 fixedly connected to the top of the frame 1, a telescopic frame 12 movably inserted into the inner wall of the support rod 11, and two connecting plates 1 fixedly connected to the outer wall of the telescopic frame 12. 3. A protective cover 14 is fixedly connected between the bottoms of the two connecting plates 13. Three second bearings 15 are fixedly inserted into the inner wall of the protective cover 14. A stirring shaft 16 is fixedly inserted into the interior of two of the three second bearings 15. A set of fixing rings 17 is fixedly fitted onto the outer wall of each of the two stirring shafts 16. Three stirring rods 18 are fixedly connected to the outer wall of each of the two sets of fixing rings 17. A rotating shaft 19 is fixedly inserted into the interior of one of the three second bearings 15. A third gear 20 is fixedly fitted onto the outer wall of both the two stirring shafts 16 and the rotating shaft 19. A second protective box 21 is fixedly connected to the top of the telescopic frame 12. A stirring motor 22 is fixedly connected to the inner wall of the second protective box 21. The output end of the stirring motor 22 is fixedly connected to the top of the rotating shaft 19. A hydraulic rod 23 is fixedly connected to the top of the frame 1. The bottom of the telescopic frame 12 is fixedly connected to the telescopic end of the hydraulic rod 23.

[0026] The overall effect achieved in Embodiment 1 is as follows: When it is necessary to stir the lithium-ion battery raw materials inside the stirring tank 10, the rotary motor 8 and the stirring motor 22 are started first. The rotary motor 8 drives the second gear 6 to rotate, and through the gear set transmission, the support column 4 and the rotating disk 9 rotate, thereby driving the stirring tank 10 to rotate. At the same time, the output end of the stirring motor 22 drives the rotating shaft 19 and the third gear 20 on its outer wall to rotate. Because the three third gears 20 mesh with each other, the rotation of the middle third gear 20 will drive the third gears 20 on both sides to rotate synchronously. The stirring shaft 16 and six stirring rods 18 rotate, and the six stirring rods 18 rotate alternately, causing the raw materials in the stirring tank 10 to form a complex flow trajectory. The inclined stirring rods 18 can further enhance the shearing and tumbling effect on the raw materials. In addition, the stirring tank 10 and the six stirring rods 18 rotate in opposite directions, so that the raw materials in the stirring tank 10 are subjected to forces in different directions, which further improves the uniformity of stirring, ensures that the lithium-ion battery raw materials are fully mixed, and allows the components of the electrode material to be evenly distributed, and the active materials, conductive agents, etc. to be fully dispersed.

[0027] Example 2, as Figure 2-4 As shown, a third protective box 24 is fixedly connected to the top of the protective cover 14, and two fixed plates 25 are fixedly connected to the top of the rotating disk 9. Threaded grooves 26 are opened on one side of the outer wall of each of the two fixed plates 25. Fastening screws 27 are threadedly connected to the inner surface of each of the two threaded grooves 26. Knobs 28 are fixedly connected to one side of the outer wall of each of the two fastening screws 27. Third bearings 29 are fixedly sleeved on the outer surface of each of the two fastening screws 27. Clamping blocks 30 are fixedly sleeved on the outer surface of each of the two third bearings 29. A set of guide rods 31 is fixedly connected to one side of the outer wall of each of the two clamping blocks 30, and the two sets of guide rods 31 are movably inserted into the interior of the two fixed plates 25. Two sliding grooves 32 are opened on the top of the rotating disk 9. Sliding sliders 33 are slidably embedded in the inner surface of each of the two sliding grooves 32, and the bottom of the two clamping blocks 30 is fixedly connected to the top of the two sliding sliders 33.

[0028] The effect achieved by the entire embodiment 2 is as follows: when it is necessary to perform a rotary stirring operation on the mixing tank 10, first turn the two knobs 28. The knobs 28 drive the fastening screw 27 to rotate. With the threaded transmission cooperation between the fastening screw 27 and the threaded groove 26, the fastening screw 27 achieves horizontal displacement during rotation. The fastening screw 27 drives the clamping block 30 to move synchronously through the third bearing 29, causing the two clamping blocks 30 to gradually move closer to the mixing tank 10, thereby forming a stable clamp on the mixing tank 10, ensuring that the mixing tank 10 maintains a stable position during rotation, thereby effectively improving the stability and reliability of the stirring operation and ensuring the stirring quality of lithium-ion battery raw materials.

[0029] The working principle of the entire device is as follows: First, the hydraulic rod 23 is activated, its telescopic end driving the telescopic frame 12 to move vertically upwards. The telescopic frame 12 simultaneously lifts the protective cover 14 through two connecting plates 13, exposing the opening of the mixing tank 10, facilitating the accurate addition of lithium-ion battery raw materials into the tank. Then, the two knobs 28 are rotated, driving the fastening screw 27 to rotate. Through the threaded transmission with the threaded groove 26, the fastening screw 27 generates horizontal displacement, which, through the third bearing 29, drives the clamping blocks 30 to move synchronously. The two clamping blocks 30 move towards each other, firmly clamping the mixing tank 10, ensuring its stability during high-speed rotation and preventing shaking or displacement. After clamping and fixing, the rotary motor 8 and the stirring motor 22 are started. The rotary motor 8 drives the second gear... The rotation of wheel 6, driven by the first gear 5, drives the support column 4 and the rotating disk 9 to rotate, realizing the overall rotation of the mixing tank 10. At the same time, the stirring motor 22 drives the rotating shaft 19 and the third gear 20 on its outer wall to rotate. The three meshing third gears 20 make the middle gear drive the gears on both sides to rotate synchronously, thereby driving the two stirring shafts 16 and the six sets of stirring rods 18 to rotate at high speed. The six sets of stirring rods 18 operate in an alternating manner, and through a complex motion trajectory, they drive the raw materials in the tank to undergo strong convection and shear mixing. Since the mixing tank 10 and the six sets of stirring rods 18 rotate in opposite directions, the raw materials in the tank form multi-dimensional turbulence under the action of forces in different directions, further enhancing the intensity of stirring and the mixing effect, and ensuring that the lithium-ion battery raw materials are fully and uniformly mixed.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
