[0002] With the popularity of electric vehicles, energy storage systems and various portable electronic devices, lithium batteries, as efficient and environmentally friendly energy storage devices, have seen a steady increase in market demand. Technological advances have led to increasing energy density and decreasing costs for lithium batteries, further driving their widespread use in multiple fields. In this context, the lithium battery processing industry is experiencing unprecedented development opportunities, not only aligning with national policy guidance, but also becoming a promising new industry with business opportunities and potential.

[0003] The stirring step in lithium battery processing is one of the key steps to ensure battery performance. This process mainly involves feeding raw materials such as positive and negative materials, electrolyte, and conductive agents into a stirring device in a certain proportion, and mixing these raw materials uniformly through high-speed rotating stirring paddles or blades. However, current stirring equipment cannot accurately control the batch feeding of different raw materials into the stirring barrel. This limitation results in suboptimal raw material feeding order, which affects the mixing effect of the slurry and the quality of the final product. In addition, during the stirring process, the inner edge and bottom area of the stirring barrel often become a stirring blind area, making it difficult for raw materials in these areas to fully participate in mixing, which affects the uniformity of raw material stirring. This problem not only reduces the quality of lithium battery slurry, but also may adversely affect the performance and safety of the battery. Therefore, we propose an automatic feeding stirring equipment. SUMMARY

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figures 1-11 This utility model provides a technical solution:

[0030] An automatic feeding and mixing device includes a first-layer component 1, a second-layer component 2 below the first-layer component 1, a support frame 3 fixedly installed on the outside of the first-layer component 1, a mixing component 5 installed below the second-layer component 2, and a mixing container 4 below the mixing component 5.

[0031] One layer of component 1 includes a housing 11. A pad 12 is fixedly connected to the center of the housing 11. A first motor 13 is mounted on the pad 12. A first rotating shaft 14 is located to the right of the first motor 13. A first gear 15 is fixedly connected to the outside of the first rotating shaft 14. A second gear 16 is located below the first gear 15 and meshes with it. A lead screw 17 is fixedly connected below the second gear 16, and a lead screw nut 18 is mounted on the outside of the lead screw 17. The pad 12 stably supports the first motor 13. After the first motor 13 starts, it drives the first rotating shaft 14 to rotate, which in turn drives the connected first gear 15 to rotate synchronously. Because the first gear 15 and the second gear 16 mesh, when the first gear 15 rotates, the second gear 16 also rotates. As the second gear 16 rotates, it drives the lead screw 17 to rotate. The rotation of the lead screw 17 causes the lead screw nut 18 to move up and down along the threaded path of the lead screw 17, achieving vertical displacement control.

[0032] A feeding assembly 19 is provided near the side wall inside the outer shell 11. The feeding assembly includes a feeding cylinder 191, which is fixedly connected to the top plate of the outer shell 11. A rotation control assembly 192 is installed between the four feeding cylinders 191. The rotation control assembly 192 includes four first sleeves 1921 nested together. The four first sleeves 1921 are rotatably connected by bearings. The top surface of each first sleeve 1921 is located on the same plane, and the bottom of each first sleeve 1921 is shortened from the inside to the outside. A rotating handle 1922 is fixedly connected to the first sleeve 1921. A connecting rod 1923 is fixedly connected to the bottom of the first sleeve 1921. A blade 1924 is fixedly connected to the side of the connecting rod 1923 away from the first sleeve 1921. A first conveying pipe 193 is provided below the feed cylinder 191, and a gap 1911 exists between the feed cylinder 191 and the first conveying pipe 193. The blade 1924 can enter this gap 1911, and after entering, its upper and lower sides contact the bottom end of the feed cylinder 191 and the top end of the first conveying pipe 193, respectively. The first conveying pipe 193 is fixedly connected to the bottom plate of the outer shell 11. A second conveying pipe 194 is fixedly connected below the first conveying pipe 193, and the top of the second conveying pipe 194 is connected to the bottom of the four first conveying pipes 193. The raw material first flows smoothly into the first conveying pipe 193 through the first sleeve 1921, and after gathering inside the pipe, it is further guided to the second conveying pipe 194, and finally enters the mixing container 4. By rotating the rotating handle 1922, the first sleeve 1921 connected to it is rotated, and then, through the transmission action of the connecting rod 1923, the blade 1924 also rotates and moves accordingly.

[0033] It should be noted that the blades 1924 in the rotary control assembly 192 are matched with the gap 1911 in the middle of the feed cylinder 191. When the rotary handle 1922 is moved, the first sleeve 1921 connected to it will drive the blades 1924 to move within the gap 1911. The first sleeves 1921 are rotatably connected by bearings, so they can rotate independently, thereby guiding the raw materials into the corresponding first conveying pipe 193. Different raw materials can be placed in the four first sleeves 1921. By rotating the different first sleeves 1921, the order in which different raw materials enter the mixing container can be flexibly controlled.

[0034] It should be noted that when the first sleeve 1921 is rotated, the blade 1924 will also rotate. As the blade 1924 enters the gap 1911, it will block different sizes of the bottom area of ​​the feed cylinder 191. By adjusting the area blocked by the blade 1924, the feed rate of the raw material can be effectively controlled, and different feed rates can be adjusted.

[0035] The second-layer component 2 includes a second outer shell 21. Limiting blocks 22 are fixedly connected to both sides of the second outer shell 21. A second motor 23 is fixedly connected to the inner bottom plate of the second outer shell 21. The transmission shaft on the second motor 23 is fixedly connected to the first track axle wheel 24. A second rotating shaft 26 is provided on the left side of the first track axle wheel 24. A track 25 is installed outside the second rotating shaft 26 and the first track axle wheel 24. The second motor 23 inside the second outer shell 21 drives the first track axle wheel 24 to rotate, and the transmission of the track 25 drives the second rotating shaft 26 to rotate.

[0036] It should be noted that the lead screw nut 18 is fixedly connected to the top plate of the second-layer outer shell 21. When the lead screw nut 18 moves up and down along the threaded trajectory of the lead screw 17, it drives the entire second-layer assembly 2 to move up and down.

[0037] The support frame 3 includes a slide groove 31, which matches the limiting block 22 outside the second-layer component 2. When the second-layer component 2 moves up and down, it drives the limiting block 22 to move up and down in the slide groove 31, so that the lead screw nut 18 will not slip on the lead screw 17 during high-speed rotation.

[0038] The mixing container 4 includes a mixing drum 41. A handle 42 is fixedly installed on the front side of the mixing drum 41, and four casters 43 are symmetrically fixedly installed on the lower part of the mixing drum 41. The direction of the casters 43 installed on the mixing drum 41 can be easily adjusted using the handle 42, thereby conveniently moving the mixing container 4 to the desired position.

[0039] The stirring assembly 5 includes a top plate 51, with a telescopic stirring assembly 52 symmetrically fixedly installed below the top plate 51. S-shaped stirring rods 53 are also symmetrically fixedly installed below the top plate 51, and are perpendicular to the telescopic stirring assembly 52. ​​The telescopic stirring assembly 52 includes a long rod 521, with a movable second sleeve 522 fitted over it. A first telescopic rod 523 is fixedly connected to the left side of the second sleeve 522, and a second telescopic rod 524 is fixedly connected to the bottom of the long rod 521. A short rod 525 is provided between the first and second telescopic rods 523 and parallel to the long rod 521. Moving the second sleeve 522 causes the first telescopic rod 523 to move accordingly. By tightening the screws, the current positions of the first and second telescopic rods 523 and 524 can be effectively fixed, ensuring that the edge of the telescopic stirring assembly 52 can fit against the inner wall of the stirring drum 41. During the mixing process, the telescopic mixing component 52 can focus on mixing the edge area of ​​the mixing drum 41, while the S-shaped mixing roller 53 is responsible for mixing the inner area of ​​the mixing drum 41. The two work together to ensure the uniformity and efficiency of mixing.

[0040] It should be noted that the stirring component 5 is fixedly connected to the second rotating shaft 26 in the second-layer component 2. Therefore, when the second-layer component 2 moves up and down, the stirring component 5 will also move up and down accordingly. In addition, when the second rotating shaft 26 starts to rotate, the stirring component 5 will rotate synchronously with it to ensure the effective execution of the stirring action.

[0041] By adjusting the direction of the casters 43 mounted on the mixing drum 41 using handle 42, the mixing container 4 can be easily moved into the equipment. Then, the first motor 13 is started, driving the first rotating shaft 14 to rotate, which in turn drives the connected first gear 15 to rotate synchronously. Since the first gear 15 meshes with the second gear 16, the second gear 16 rotates as the first gear 15 rotates. The rotation of the second gear 16 drives the lead screw 17 to rotate. The rotation of the lead screw 17 causes the lead screw nut 18 to move up and down along the threaded path of the lead screw 17, achieving vertical displacement control. The lead screw nut 18 is fixedly connected to the top plate of the second-layer outer shell 21. When the lead screw nut 18 moves up and down along the threaded path of the lead screw 17, it drives the entire second-layer assembly 2 to move up and down. When the second-layer assembly 2 moves up and down, it drives the limit block 22 to move up and down in the slide groove 31, preventing the lead screw nut 18 from slipping on the lead screw 17 during high-speed rotation. The stirring component 5 is fixedly connected to the second rotating shaft 26 in the second-layer component 2. Therefore, when the second-layer component 2 moves up and down, the stirring component 5 will also move up and down accordingly.

[0042] Lower the stirring assembly 5 to near the bottom of the mixing container 4 and turn off the first motor 13. Move the second sleeve 522 to bring the first telescopic rod 523 closer to the edge of the mixing drum. By tightening the screws, we can effectively fix the current positions of the first telescopic rod 523 and the second telescopic rod 524, ensuring that the edge of the telescopic stirring assembly 52 can fit against the inner wall of the mixing drum 41. During the stirring process, the telescopic stirring assembly 52 can focus on stirring the edge area of ​​the mixing drum 41, while the S-shaped stirring rod 53 is responsible for stirring the inner area of ​​the mixing drum 41. The two work together to ensure the uniformity and efficiency of the stirring.

[0043] Different raw materials can be placed in the four first sleeves 1921. The raw materials flow smoothly into the first conveying pipe 193 through the first sleeves 1921, and after gathering in the pipe, are further guided to the second conveying pipe 194, and finally enter the mixing container 4. Rotating the rotating handle 1922 causes the connected first sleeves 1921 to rotate, which in turn causes the blades 1924 to rotate and move accordingly through the connecting rod 1923. The blades 1924 in the rotation control assembly 192 match the gap 1911 in the middle of the feed cylinder 191. When the rotating handle 1922 is moved, the connected first sleeves 1921 drive the blades 1924 to move in the gap 1911. As the blades 1924 enter the gap 1911, they block different areas of the bottom of the feed cylinder 191. By adjusting the area blocked by the blades 1924, the feed rate of the raw materials can be effectively controlled, and different feed rates can be adjusted. The first sleeves 1921 are rotatably connected by bearings, allowing them to rotate independently and guide raw materials into the corresponding first conveying pipe 193. Users can flexibly control the order in which different raw materials enter the mixing container.

[0044] Then, the second motor 23 inside the second outer shell 21 is activated. The second motor 23 drives the first track axle wheel 24 to rotate, and the transmission of the track 25 drives the second rotating shaft 26 to rotate. When the second rotating shaft 26 starts to rotate, the stirring assembly 5 will rotate synchronously with it to ensure the effective execution of the stirring action.

[0045] After mixing is complete, turn off the second motor 23 and then start the first motor 13 to reset the entire second-layer assembly 2 and the mixing assembly 5. Then, use the handle 42 to adjust the direction of the casters 43 installed on the mixing drum 41, so as to easily move the mixing container 4 outside the equipment.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
