However, solid-state battery production involves a variety of materials with different properties, such as positive electrode materials and negative electrode materials with different formulations. Each material requires a different grinding area and method. Since traditional ball mills cannot adjust the grinding area according to the material characteristics, insufficient grinding or over-grinding often occurs, resulting in unstable product quality. Therefore, the above problems need to be solved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a ball mill for solid-state battery production and processing, comprising a base plate 2, on which two mounting seats are installed, and a cylinder 1 is rotatably disposed between the two mounting seats. The cylinder 1 facilitates stable containment of materials and balls 12, ensuring continuous grinding operations. A ball-feeding pipe is welded to the top of the cylinder 1, and a cover plate 7 is hinged to the ball-feeding pipe. The cover plate 7 facilitates the sealing of the ball mill, reducing the loss of materials and balls 12. Operation is convenient, facilitating equipment maintenance and ball 12 replenishment. A large gear ring 9 is fixedly connected to one end of the cylinder 1, which facilitates stable and efficient power transmission, ensuring the smooth operation of the cylinder 1. Stable rotation ensures the normal operation of the grinding process. A feed pipe 6 is fixedly connected to the other end of the cylinder 1, facilitating the orderly transport of materials and preventing blockages. A feed spiral 11 is provided on the inner wall of the feed pipe 6, allowing materials to enter the cylinder 1 evenly and smoothly, preventing material accumulation and blockage within the feed pipe 6 and improving feeding efficiency. An electric valve is installed inside the feed pipe 6, and a limiting component is provided inside the cylinder 1. A ball 12 is placed inside the limiting component, facilitating the grinding of solid-state battery materials to the required particle size, improving material activity and uniformity, and meeting production process requirements.

[0020] In this utility model, the limiting component includes a groove formed on the inner wall of the cylinder 1. A baffle 13 is slidably mounted inside the cylinder 1 through the groove. A motor is mounted on one side of the baffle 13. The limiting component allows for flexible adjustment of the position of the baffle 13 according to different materials and grinding process requirements, precisely controlling the grinding process and improving the controllability of the grinding effect. A first vacuum pump 3 for sucking solid-state batteries is installed at one end of the top of the bottom plate 2. A first pipe 8 is provided between the first vacuum pump 3 and the cylinder 1. The first vacuum pump 3 facilitates fast and accurate material delivery, improving feeding efficiency and reducing manual operation. A motor 5 is mounted on the bottom plate 2. The motor 5 delivers... A matching gear is fixedly connected to the outlet end, and the gear meshes with the large gear ring 9. The motor 5 provides a stable and continuous power output to ensure that the cylinder 1 operates at a set speed. A second vacuum pump 4 for argon gas is installed at the other end of the top of the bottom plate 2. A second pipe is provided between the second vacuum pump 4 and the cylinder 1. The second vacuum pump 4 effectively protects the chemical properties of the solid-state battery materials, avoids the degradation of material properties due to oxidation, and improves product quality and stability. A stone slab 10 is attached to the inner wall of the cylinder 1. The stone slab 10 is made of alumina ceramic material. The stone slab 10 helps to improve grinding efficiency and quality and ensure the uniformity of material grinding.

[0021] Working Principle: In the use of this utility model, the motor 5 serves as the power core of the ball mill. After starting, it outputs rotational power. The gear at the output end of the motor 5 meshes with the large gear ring 9 fixed to one end of the cylinder 1. Through gear transmission, the rotational motion of the motor 5 is converted into the rotation of the cylinder 1. Then, in the feeding stage, the first vacuum pump 4 is connected to the cylinder 1 through the first pipe 8. After starting, it forms a negative pressure. The solid-state battery material enters through the feed pipe 6. The feed spiral 11 on the inner wall of the feed pipe 6 guides and pushes the material, allowing it to enter the cylinder 1 quickly and orderly under the dual action of vacuum suction and spiral pushing. The electric valve in the feed pipe 6 can precisely control the opening and closing of the feed according to production needs, adjusting the feed amount and feed speed to ensure the continuity of the grinding process. Then, during the grinding operation, when the cylinder 1 rotates, the balls 12 placed inside rise to a certain height with the cylinder 1 under the action of centrifugal force and friction, and then fall, colliding and rubbing against the solid-state battery material. At the same time, the cylinder... The rotation of body 1 causes the balls 12 to tumble and move continuously inside the cylinder, grinding the material from multiple angles to achieve the required particle size for solid-state battery materials, thereby improving the activity and uniformity of the materials. During the grinding process, the alumina ceramic slabs 10 attached to the inner wall of body 1, with their high wear resistance and corrosion resistance, not only protect the inner wall of body 1 but also participate in the grinding. Then, the baffle 13 in the limiting assembly slides through the grooves on the inner wall of body 1 and is driven by a motor. According to the characteristics of different solid-state battery materials and grinding process requirements, the position of the baffle 13 inside body 1 can be adjusted by controlling the motor to drive the baffle 13, thereby limiting the movement range of the balls 12 and changing the grinding area. Finally, when it is necessary to add balls 12, the cover plate 7 hinged to the ball adding tube is opened, and the balls 12 are placed into the inside of body 1 through the ball adding tube. The cover plate 7 is closed when the ball mill is running to prevent the balls 12 and materials from overflowing from the ball adding tube, ensuring the sealing of the ball mill. This concludes the use of the ball mill for solid-state battery production and processing.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
