[0029] A feed pipe 4 is fixed on the top of the batching tank 1 , and the interior of the feed pipe 4 is connected to the interior of the batching tank 1 . By arranging the feed pipe 4 on the top of the batching tank 1 , the lithium ion raw material that has been batched can be added to the interior of the batching tank 1 through the feed pipe 4 .

[0030] A liquid inlet pipe 5 is fixed to the side of the batching tank 1, and one end of the liquid inlet pipe 5 passes through the bottom of the partition 3. Through the setting of the liquid inlet pipe 5, the liquid required for the mixed raw materials can be added to the interior of the batching tank 1 through the liquid inlet pipe 5.

[0031] An observation window 7 is provided on the side of the batching tank 1 . Through the setting of the observation window 7 , the situation inside the batching tank 1 can be observed through the observation window 7 during operation.

[0032] A base 8 is provided at the bottom of the batching tank 1, and a plurality of support plates 81 are fixed on the top of the base 8. One side of the plurality of support plates 81 is fixed to the side surface of the batching tank 1. Through the arrangement of the base 8 and the plurality of support plates 81, the batching tank 1 can be stably supported.

[0033] like Figure 2 and Figure 3 As shown, the stirring and adjusting assembly includes: an adjusting groove 2 and a placement groove 21 opened at the bottom of the stirring shaft 12 from bottom to top, a plurality of half gear rods 22 rotatably connected to the inner side of the adjusting groove 2 near the bottom, and a plurality of stirring blades 23 fixed to the plurality of half gear rods 22 at one end outside the adjusting groove 2; a driven gear 24 and a driving gear 25 are sequentially arranged on the top of the half gear rod 22.

[0034] An electric telescopic rod 26 is fixed inside the placement slot 21 , and a rack 27 is fixed to the output end of the electric telescopic rod 26 located inside the adjustment slot 2 , and one side of the rack 27 is meshed with the side surface of the driving gear 25 .

[0035] It should be noted that a plurality of half gear rods 22 are symmetrically arranged on the inner side of the adjusting groove 2, the side surfaces of adjacent half gear rods 22 are meshed with each other, and one end of the half gear rod 22 is in conflict with the inner side of the adjusting groove 2; the driven gear 24 and the driving gear 25 are both rotatably connected to the inner side of the adjusting groove 2, and the side surfaces of the driven gear 24 are respectively meshed with the side surfaces of the half gear rod 22 and the driving gear 25; the number of the half gear rods 22 and the stirring blades 23 are preferably two, and the angle between the half gear rod 22 and the stirring shaft 12 is adjusted to 0-90°; when it is necessary to adjust the angle between the stirring blade 23 and the stirring shaft 12, the electric telescopic rod 26 is started to retract the feed amount, which can drive the rack 27 to move upward, and the rack 27 is meshed with the driving gear 25, and the rack 27 moves up and down. When the electric telescopic rod 26 is started, the driving gear 25 can be driven to rotate counterclockwise, and the driven gear 24 can mesh with the driving gear 25 upward and mesh with the half gear rod 22 downward. When the driving gear 25 rotates, the driven gear 24 will rotate clockwise, and the half gear rod 22 will drive the stirring blade 23 at one end to rotate counterclockwise, thereby driving the stirring blade 23 to flip downward and reduce the angle between the stirring blade 23 and the stirring shaft 12. Conversely, when the electric telescopic rod 26 is started to extend the feed amount, the stirring blade 23 can be driven to flip upward and increase the angle between the stirring blade 23 and the stirring shaft 12, so as to adjust the change of the resistance of the stirring blade 23. When the easily mixed raw materials are stirred, the size of the resistance is appropriately adjusted, thereby achieving the effect of reducing energy consumption.

[0036] A partition 3 is fixed on the inner side of the batching tank 1 near the top, a plurality of leakage holes are opened on the surface of the partition 3, and a plurality of scraping rods 31 are fixed on the side of the stirring shaft 12 located at the top of the partition 3.

[0037] It should be noted that the bottom of the scraper rod 31 is in contact with the top of the partition 3; a number of scraper rods 31 are evenly distributed on the side of the stirring shaft 12; when the lithium-ion battery raw materials are completed and enter the mixing tank 1, and fall on the top of the partition 3, while the stirring shaft 12 rotates, it can drive a number of scraper rods 31 on the side of the stirring shaft 12 to rotate synchronously, which can scrape the raw materials and evenly spread them on the top of the partition 3, and fall into the mixed liquid through a number of leakage holes on the surface of the partition 3 for uniform mixing, thereby avoiding more raw materials falling into the mixed liquid at the same time, resulting in agglomeration and difficulty in mixing, thereby improving the practicability of the device.

[0038] A discharge pipe 6 is fixed at the bottom of the batching tank 1 , and a valve 61 is arranged on the side of the discharge pipe 6 . Through the arrangement of the discharge pipe 6 and the valve 61 , after the mixing is completed, the valve 61 is opened and the product can be discharged through the discharge pipe 6 .

[0039] When the utility model is used, the liquid required for the mixed raw materials is added to the interior of the batching tank 1 through the liquid inlet pipe 5. When it is necessary to adjust the angle between the stirring blade 23 and the stirring shaft 12, the electric telescopic rod 26 is started to shrink the feed amount, which can drive the rack 27 to move upward, and the rack 27 is meshed with the driving gear 25. When the rack 27 moves up and down, the driving gear 25 can be driven to rotate counterclockwise, and the driven gear 24 is meshed with the driving gear 25 upward and meshed with the half gear rod 22 downward. When the driving gear 25 rotates, the driven gear 24 will rotate clockwise, and the half gear rod 22 will drive the stirring blade 23 at one end to rotate counterclockwise, and then the stirring blade 23 can be driven to flip downward, reducing the angle between the stirring blade 23 and the stirring shaft 12. Conversely, when the electric telescopic rod 26 is started to extend the feed amount, the stirring blade 23 flips upward to increase the angle between the stirring blade 23 and the stirring shaft 12, so as to adjust the change of the resistance of the stirring blade 23. When stirring the easily mixed raw materials, the size of the resistance is appropriately adjusted to achieve the effect of reducing energy consumption. Starting the servo motor 11 can drive the stirring shaft 12 to rotate, and the lithium ion raw material that has been prepared is added to the inside of the preparation tank 1 through the feeding pipe 4, and falls into the top of the partition 3. While the stirring shaft 12 rotates, it can drive a number of scraper rods 31 on the side of the stirring shaft 12 to rotate synchronously, which can scrape the raw materials and evenly spread them on the top of the partition 3, and fall into the preparation liquid through a number of leakage holes on the surface of the partition 3 for uniform mixing, thereby avoiding more raw materials falling into the preparation liquid at the same time, resulting in agglomeration and difficulty in mixing. After the mixing is completed, the valve 61 is opened to discharge the product through the discharge pipe 6.
