Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1-4, an embodiment provided by the present utility model: a batching device for graphite anode materials, including a base 1, a mixing barrel 5 is fixedly connected to the top end of the base 1, a support plate 25 is fixedly connected to the rear end of the left side of the mixing barrel 5, a second motor 7 is fixedly connected to the left side of the support plate 25, the driving end of the second motor 7 penetrates through the outer wall of the support plate 25 and is fixedly connected to a second gear 13, a second stirring roller 19 is fixedly connected to the right end of the second gear 13, a first gear 12 is meshed and connected to the front end of the second gear 13, a first stirring roller 17 is fixedly connected to the right end of the first gear 12, a plurality of stirring rods 18 are fixedly connected to the outer walls of the four sides of the first stirring roller 17 and the second stirring roller 19, a plurality of fixing blocks 10 are fixedly connected to the front side of the top end of the base 1, a rotating rod 23 is slidably connected to the inner wall of the fixing block 10, a third gear 8 is fixedly connected to the left end of the rotating rod 23, the rear end of the third gear 8 is meshed and connected to the front end of the first gear 12, a plurality of ratchets 22 are fixedly connected to the outer wall of the rotating rod 23, a plurality of fixing plates 20 are fixedly connected to the outer edge of the front side of the top of the base 1, the number of the fixing plates 20 is the same as that of the ratchets 22, a support rod 24 is rotatably connected to the top end of the rear side of each fixing plate 20, a hammer 9 is fixedly connected to the top end of each support rod 24, a spring 21 is fixedly connected to the top of the front end of each support rod 24, the front ends of the springs 21 are fixedly connected to the rear side of the fixing plate 20, the right end of the second gear 13 is rotatably connected to the rear end of the outer wall of the left side of the mixing barrel 5, the right end of the first gear 12 is rotatably connected to the front end of the outer wall of the left side of the mixing barrel 5, the right end of the first stirring roller 17 is rotatably connected to the front side of the inner wall of the right end of the mixing barrel 5, the right end of the second stirring roller 19 is rotatably connected to the rear side of the inner wall of the right end of the mixing barrel 5, and support legs 2 are fixedly connected to the four corner ends of the bottom of the base 1

[0024] Specifically, the hammer 9 is made of rubber to prevent damage to the mixing barrel 5 and affect the mixing degree. When mixing materials, first turn on the second motor 7, and its driving end rotates counterclockwise, thereby driving the second gear 13 to rotate counterclockwise, which will drive the second stirring roller 19 to rotate counterclockwise. The second gear 13 will also drive the first gear 12 to rotate clockwise, thereby driving the first stirring roller 17 to rotate clockwise. At this time, the second stirring roller 19 and the first stirring roller 17 will each drive the stirring rod 18 to rotate. At this time, the first gear 12 will drive the third gear 8 to rotate counterclockwise. At this time, the third gear 8 will drive the rotating rod 23 to rotate counterclockwise, thereby driving the ratchet 22 to rotate counterclockwise. When the ratchet 22 rotates counterclockwise, a tooth of the ratchet 22 will continuously lift the bottom of the support rod 24 upward and compress the spring 21. When the tooth rotates to a certain extent, it will no longer be able to lift the bottom of the spring 21 upward and will disengage from the bottom of the support rod 24. At this time, under the reaction force of the spring 21, the support rod 24 will be pushed outward violently and drive the hammer 9 to hammer the mixing barrel 5. At this time, the support rod 24 will repeat hammering the outer wall of the mixing barrel 5 under the next tooth of the ratchet 22 until the mixed materials are evenly mixed.

[0025] A feeding hopper 6 is fixedly connected to the top of the mixing barrel 5. Storage bins 3 are fixedly connected to the top and the front and rear sides of the feeding hopper 6. First motors 4 are fixedly connected to the right sides of the storage bins 3. The driving ends of the first motors 4 penetrate through the outer walls of the right ends of the storage bins 3 and are fixedly connected to screw rods 11. The left ends of the screw rods 11 are rotatably connected to the inner walls of the storage bins 3. A discharge port 15 is fixedly connected to the bottom end of the mixing barrel 5. A third motor 14 is fixedly connected to the left end of the discharge port 15. The driving end of the third motor 14 penetrates through the outer wall of the left end of the discharge port 15 and is fixedly connected to a discharge valve 16. The right side of the discharge valve 16 is rotatably connected to the inner wall of the discharge port 15.

[0026] Specifically, the mixed materials are separately loaded into the storage bins 3, and then the first motors 4 are turned on for feeding. The first motors 4 will drive the screw rods 11 to rotate, and the screw rods 11 will uniformly push the mixed materials towards the feeding hopper 6. Then, according to the proportion of the mixed materials, the first motors 4 for feeding different mixed materials are sequentially turned off. At this time, the mixed materials will enter the mixing barrel 5 from the feeding hopper 6 for the mixing step. After mixing is completed, the third motor 14 on the discharge port 15 is turned on, which will drive the discharge valve 16 to rotate and uniformly feed downward.

[0027] Working principle: The mixed materials are separately placed into the storage bin 3. The first motor 4 is turned on, and the first motor 4 drives the screw rod 11 to rotate. The screw rod 11 will evenly push the mixed materials towards the feed hopper 6. Then, according to the proportion of the mixed materials, the first motor 4 for feeding different mixed materials is turned off in sequence. The mixed materials will be sent to the mixing barrel 5 by the feed hopper 6. The second motor 7 is turned on, and its driving end rotates counterclockwise, thereby driving the second gear 13 to rotate counterclockwise. It drives the second stirring roller 19 to rotate counterclockwise. The second gear 13 also drives the first gear 12 to rotate clockwise, thereby driving the first stirring roller 17 to rotate clockwise. When mixing mixed materials such as graphite, the two stirring rollers can rotate in different reverse directions for stirring. The second stirring roller 19 and the first stirring roller 17 each drive the stirring rod 18 to rotate. At this time, the first gear 12 will drive the third gear 8 to rotate counterclockwise. At this time, the third gear 8 will drive the rotating rod 23 to rotate counterclockwise, thereby driving the ratchet 22 to rotate counterclockwise. When the ratchet 22 rotates counterclockwise, a tooth of the ratchet 22 will continuously lift the bottom of the support rod 24 upward and compress the spring 21. When the tooth rotates to a certain extent, it will no longer be able to lift the bottom of the spring 21 upward and will separate from the bottom of the support rod 24. At this time, under the reaction force of the spring 21, it will push the support rod 24 outward violently and drive the hammer 9 to hammer towards the mixing barrel 5. At this time, the support rod 24 will repeat hammering the outer wall of the mixing barrel 5 under the next tooth of the ratchet 22. It realizes that while stirring, the hammer 9 continuously knocks on the barrel wall, so that the mixed materials sticking to the barrel wall fall off and participate in the mixing. Under their combined action, the mixing degree of the materials is improved and the proportion error of the ingredients is reduced, improving the use effect of the mixed product. After mixing for a period of time and meeting the mixing requirements, the operation of the second motor 7 is stopped, and the third motor 14 is turned on. It drives the discharge valve 16 to rotate. The mixed materials are discharged from the discharge port 15 under the influence of the rotation of the discharge valve 16. The rotation speed of the discharge valve 16 will affect the discharge speed. Since the feeding is controlled by the first motor 4 and the discharging is controlled by the discharge valve 16 and both can operate evenly, the controllability of the feeding and discharging speeds is realized, so that the inflow and outflow speeds of the materials are kept stable, thereby making the entire production process more stable and controllable, which helps to improve the product quality and production efficiency.
