[0034] The inside of the fixed support plate 3 is rotatably connected with a rotating connecting column 6, which is in a cylindrical shape. The rotating connecting column 6 is driven to rotate by the driving wheel 7 and the driven wheel 9. One half of the rotating connecting column 6 is externally connected with a transmission assembly, which includes the driving wheel 7 in a disc shape. The driving wheel 7 drives the driven wheel 9 to rotate through the connecting belt 8, thereby synchronously rotating the two rotating connecting columns 6. The inside of the driving wheel 7 is fixedly connected to the outside of one half of the rotating connecting column 6. The outside of the driving wheel 7 is coupled with the connecting belt 8, which transmits the rotating force to the driven wheel 9 and the fixed connecting block 10. The inside of the driven wheel 9 is coupled with the connecting belt 8, which is fixedly connected to the outside of the other half of the rotating connecting column 6. The top of the driven wheel 9 is rotatably connected to the bottom of one half of the fixed support plate 3.

[0035] The transmission assembly is fixedly connected with the fixed connecting block 10 in a cuboid shape, which rotates with the connecting belt 8. The bottom of the fixed connecting block 10 is fixedly connected with a power assembly, which includes a protective support shell 11 in a cuboid shape, which protects the second motor 12. The bottom of the protective support shell 11 is fixedly connected to the outside of the fixed connecting block 10. The inside of the protective support shell 11 is fixedly connected with the second motor 12. The driving end of the second motor 12 is fixedly connected with a second rotating connecting shaft 13 in a cylindrical shape, which is driven to rotate by the second motor 12 and transmits the rotating force to the connecting flat plate 14. The connecting flat plate 14 is in a rectangular plate shape, which provides support force for the turning fork plate 15 and drives the turning fork plate 15 to rotate.

[0036] Referring to Figure 1 , Figure 2 and Figure 4 , the inside of the drying box body 1 is fixedly connected with a drying mechanism on the left and right sides. The drying mechanism includes a heating wire 17, which can rapidly generate heat after being electrified to provide the heat source required for drying the inside of the drying box body 1. The outside of the heating wire 17 is fixedly connected to the inside of the drying box body 1 on the left and right sides. The inside of the drying box body 1 is fixedly connected with a fan 18 on the left and right sides. When the fan 18 works, the motor drives the blade to rotate at a high speed to generate airflow. The function is to uniformly blow the heat generated by the heating wire 17 to the inside of the drying box body 1 to accelerate air flow and improve drying efficiency, so that the lithium battery positive material can be quickly and uniformly heated and dried.

[0037] The upper end of the drying box body 1 is fixed with a sliding drawer 19, and a plurality of circular holes are formed in the bottom, so that the absorption sponge 20 in the sliding drawer 19 can absorb the water vapor in the drying box body 1, and the inside of the absorption sponge 20 can be replaced by pulling out or pushing into the drying box body 1. The inside of the sliding drawer 19 is provided with an absorption mechanism, which comprises the absorption sponge 20. The absorption sponge 20 is block-shaped and can absorb the water vapor generated during the drying process, so as to maintain the dry environment in the drying box body 1. The bottom of the absorption sponge 20 is placed in the inside of the sliding drawer 19. The upper end of the inside of the drying box body 1 is fixedly connected with an inclined drainage plate 21, which is in the shape of an inclined rectangular plate. During the drying process, the water vapor generated during the drying process will flow into the inclined drainage groove 22 along the surface of the inclined drainage plate 21 when it encounters the inclined drainage plate 21 during the rising process. The bottom of the inclined drainage plate 21 is fixedly connected with the inclined drainage groove 22, which is in the shape of a groove. The water vapor is guided to the outside of the drying box body 1 through the inclined drainage groove 22 and is finally collected by the water vapor collecting box 23. The outside of the drying box body 1 is fixedly connected with the water vapor collecting box 23, which can store the water vapor discharged from the inside of the drying box body 1.

[0038] Working principle: first, open the cabinet door of the drying box body 1, hold the handle and pull out the sliding rectangular support frame 2, place the lithium battery positive material to be dried in the fixed drying plate 16, then push the sliding rectangular support frame 2 back to the inside of the drying box body 1, start the fan 18 and the heating wire 17 to dry the lithium battery positive material, and start the first motor 4 to drive the first rotating shaft 5 to rotate during the drying process. The first rotating shaft 5 drives the rotating connecting column 6 to rotate, and the rotating connecting column 6 transmits the rotating force to the driving wheel 7, so that the driving wheel 7 rotates and transmits the rotating force to the connecting belt 8, so that the connecting belt 8 rotates and drives the driven wheel 9 to rotate. The rotation of the connecting belt 8 also makes the fixed connecting block 10 move, and at the same time, the second motor 12 in the protection support shell 11 is started, so that the second rotating shaft 13 rotates and transmits the rotating force to drive the connecting plate 14 to rotate, so that the two turning fork plates 15 at the bottom of the connecting plate 14 rotate and cross the lithium battery positive material in the fixed drying plate 16, so that the lithium battery positive material is dried uniformly.

[0039] When the lithium battery positive material is dried in the drying box 1, a large amount of water vapor is generated, and the water vapor floats upward because the water vapor has a lower density than air, continues to rise through a large number of holes in the bottom of the sliding drawer 19, is then absorbed by the absorption sponge 20 in the sliding drawer 19, and the sliding drawer 19 can be slid out of the inside of the drying box 1 through the external handle, so that the absorption sponge 20 that has absorbed water vapor for a long time can be replaced, and part of the water vapor that is not absorbed by the absorption sponge 20 continues to rise and is blocked by the inclined drainage plate 21, because the inclined drainage plate 21 is an inclined plate, so the water vapor can slide from a high place to a low place along the inclined drainage plate 21, until it falls onto the inclined drainage groove 22, so that the water vapor on the inclined drainage groove 22 also rolls on the inclined drainage groove 22, and finally falls into the water vapor collection box 23 for unified treatment.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
