[0030] Please see Figures 1-8 This utility model provides a technical solution:

[0031] A lithium battery anode granulation production device includes a reactor assembly 1 and a support and control assembly 2. The support and control assembly 2 is fixedly connected to the lower end of the reactor assembly 1. A drive assembly 3 is installed inside the reactor assembly 1, and a stirring and feeding assembly 4 is installed outside the drive assembly 3. The drive assembly 3 includes a servo motor 31. A threaded rod 32 is fixedly connected to the end of the main shaft of the servo motor 31. A fixed disk 33 is fixedly connected to the outside of the main shaft of the servo motor 31. A second electric telescopic rod 34 is fixedly connected to the inside of the fixed disk 33. A toothed rod is fixedly connected to the end of the piston rod of the second electric telescopic rod 34. The annular plate 35 and the threaded rod 32 are spirally connected to the outer side of the internal threaded cylinder 36. The front end of the internal threaded cylinder 36 is fixedly connected to the rack 37. The stirring and feeding assembly 4 includes a first sealing plate 41. The front end of the first sealing plate 41 is fixedly connected to the spiral stirring blade 42 and the stirring rod 43. The front ends of the spiral stirring blade 42 and the stirring rod 43 are both fixedly connected to the second sealing plate 44. The outer sides of the second sealing plate 44 and the first sealing plate 41 are both fixedly connected to the rubber sealing rings 46. The stirring rod 43 and the inner side of the second sealing plate 44 are both provided with blind holes 45. The outer side of the internal threaded cylinder 36 is fixedly connected to the inner side of the second sealing plate 44.

[0032] As a further implementation of this solution, the reactor assembly 1 includes a shell 11. A rotating groove 12 is formed at the front end of the shell 11. A support body 13 is fixedly connected to the front end of the shell 11. A circular ring 14 is rotatably connected to the inner side of the rotating groove 12. A receiving groove 15 is formed inside the circular ring 14. A guide post 16 is fixedly connected to the rear end of the circular ring 14. The circular ring 14 is fitted onto the outside of the drive assembly 3 through the receiving groove 15. The rear end of the guide post 16 slides inside the blind hole 45. The support control assembly 2 includes a support plate 21. The upper end of the support plate 21 is fixedly connected to the bottom end of the shell 11. A receiving groove 26 is formed at the right end of the support plate 21. A first electric telescopic rod 24 is fixedly connected to the inner side of the receiving groove 26 via a support. A guide plate 23 is fixedly connected to the inner side of the receiving groove 26. A limiting plate 25 is fixedly connected to the left end of 24. A slot 22 is provided on the left end of the limiting plate 25. A guide plate 23 is fixedly connected to the inner side of the receiving groove 26. Sliding grooves are provided at both the front and rear ends of the limiting plate 25. The limiting plate 25 is slidably connected to the guide plate 23 through the sliding grooves. The inner side of the slot 22 is in contact with the outer side of the guide column 16. With the above settings, the support control component 2 can control the rotation of the annular plate 14 and the guide column 16. During stirring, the support control component 2 and the guide column 16 are far apart, so as not to affect the stirring of the negative electrode material of the lithium battery. During feeding, the guide column 16 is limited, so that the stirring feeding component 4 can move backward to realize the feeding work. This combined working method not only reduces the space occupation, but also improves the convenience of using the device.

[0033] As a further implementation of this solution, the housing of the servo motor 31 is fixedly connected to the support body 13 by bolts. A through hole is provided on the inner side of the support body 13, and the main shaft of the servo motor 31 extends out of the through hole of the support body 13. A gap is provided between the main shaft of the servo motor 31 and the through hole of the support body 13. Through the above arrangement, the servo motor 31 provides driving force, which provides power for feeding and stirring.

[0034] As a further implementation of this solution, a toothed ring plate 35 is sleeved on the outside of the threaded rod 32, and a gap is provided between the inner side of the toothed ring plate 35 and the outer side of the threaded rod 32. A toothed rack 37 is fixed to the rear end of the toothed ring plate 35, and a sliding rod is fixedly connected to the lower part of the front end of the toothed ring plate 35. A sliding hole is opened on the inner side of the servo motor 31, and the sliding rod of the toothed ring plate 35 is slidably connected inside the sliding hole of the servo motor 31. The front end of the first sealing plate 41 is fixedly connected to the rear end of the inner threaded cylinder 36. The first sealing plate 41 and the second sealing plate 44 are both attached to the inner side of the housing 11 through rubber sealing rings 46. A fixing hole is opened on the inner side of the spiral stirring blade 42 near the stirring rod 43. Through the above settings, the efficiency and stability of the stirring and feeding process can be ensured, and not only is material residue reduced, but the cleanliness and service life of the device are also improved.

[0035] Workflow: When feeding the negative electrode material of the lithium battery, the first electric telescopic rod 24 is activated to move the limiting plate 25 to the left. The limiting plate 25 slides inside the receiving groove 26 and simultaneously slides outside the guide plate 23, which can improve the stability of the limiting plate 25 during movement. After the slot 22 of the limiting plate 25 enters the outside of the guide post 16, the second electric telescopic rod 34 is activated to move the toothed ring plate 35 forward. Initially, the toothed ring plate 35 and the internal threaded cylinder 36 are engaged by the rack 37. After the toothed ring plate 35 moves away from the internal threaded cylinder 36, the servo motor 31 is activated to drive the threaded rod 32 to rotate. The internally threaded cylinder 36 with the external spiral connection moves backward, and the internally threaded cylinder 36 drives the stirring and feeding assembly 4 to move backward as a whole. During this process, the guide post 16 slides inside the blind hole 45, which plays a role in limiting the movement of the stirring and feeding assembly 4 backward. At this time, the first sealing plate 41 is far away from the inside of the housing 11. By pushing the second sealing plate 44, the negative electrode material of the lithium battery inside the housing 11 can be separated from the inside of the housing 11. The inside of the housing 11 is scraped by the rubber sealing ring 46, which not only improves the convenience of feeding the inside of the housing 11, but also significantly reduces the residue on the inner wall of the housing 11 and improves the cleanliness of the inside of the housing 11 after feeding.

[0036] When stirring the negative electrode material of the lithium battery, following the same principle, the first sealing plate 41 protrudes from the interior of the housing 11. The stirring and feeding assembly 4 is then moved forward a certain distance, leaving space for the negative electrode material of the lithium battery to be filled inside the housing 11. After the negative electrode material is filled into the housing 11, the stirring and feeding assembly 4 is moved forward again, allowing the first sealing plate 41 to enter the interior of the housing 11, thus sealing the interior. At this time, the internal threaded cylinder 36 approaches the toothed ring plate 35. The second electric telescopic rod 34 is activated, causing the toothed ring plate 35 to move backward, engaging with the internal threaded cylinder 36. The first electric telescopic rod 24 is then activated to limit the movement. The card plate 25 is stored inside the storage groove 26, so that the inside of the card slot 22 is far away from the guide post 16. When the servo motor 31 is started, the servo motor 31 drives the threaded rod 32 and the fixed plate 33 to rotate. Through the meshing between the toothed ring plate 35 and the internal threaded cylinder 36, the internal threaded cylinder 36 will also rotate. The internal threaded cylinder 36 drives the stirring and feeding assembly 4 to rotate as a whole. Through the stirring rod 43 and the spiral stirring blade 42, the negative electrode material of the lithium battery inside the shell 11 is stirred. The rotation of the stirring and feeding assembly 4 drives the circular plate 14 to rotate through the guide post 16. The circular plate 14 rotates inside the rotating groove 12, thereby realizing the stirring of the negative electrode material of the lithium battery.

[0037] Based on the above principles, the device, through the design of the stirring and feeding component 4, can not only provide stirring for the negative electrode material of the lithium battery, but also use the pushing of the stirring and feeding component 4 to discharge the stirred raw material from inside the shell 11. This feeding method changes the traditional feeding method, significantly reduces the blockage caused by the unique characteristics of the negative electrode material of the lithium battery, and improves the practical performance of the device.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
