Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to an automatic shaking device for a sagger used in the production of lithium battery cathode materials. Background Technology

[0002] Lithium-ion battery cathode materials are typically composed of lithium-containing compounds, such as lithium cobalt oxide, lithium iron phosphate, and nickel-cobalt-manganese oxide. During the production process, cathode materials require a shaking process to ensure uniform mixing of raw materials and avoid localized uneven composition. This helps improve material performance and battery consistency, ensuring higher stability and capacity during charging and discharging. To achieve this, automatic sagger shaking devices are commonly used in lithium-ion battery cathode material production. These devices use an automated control system to adjust the speed and angle of the sagger, ensuring thorough shaking of the raw materials within the sagger and guaranteeing a uniform distribution of various components. This process is crucial for improving battery quality and performance.

[0003] The working principle of the automatic mixing device for lithium battery cathode materials production mainly relies on a mechanical drive system to shake the sagger. This device typically includes a vibrating platform or rotating shaft, which adjusts the rotation angle and vibration frequency to ensure uniform mixing of the cathode material inside the sagger. During the mixing process, the material inside the sagger is continuously agitated and stirred, achieving a fully uniform distribution and preventing clumping or uneven composition. The automatic mixing device is usually also equipped with an automatic control system that precisely controls the shaking time, speed, and intensity to ensure the stability and consistency of each shaking process.

[0004] In existing technologies, some automatic mixing devices for saggers used in the production of lithium-ion battery cathode materials mainly rely on vibration or rotation to achieve the mixing effect. While this method can promote material mixing to a certain extent, vibration or rotation can only act on the material individually, often making it difficult to achieve optimal mixing results. This results in some areas of the material in the sagger not being fully mixed, leading to an uneven distribution of the cathode material. Therefore, an automatic mixing device for saggers used in the production of lithium-ion battery cathode materials is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic mixing device for saggers used in the production of lithium battery cathode materials. It aims to improve the problem that some existing automatic mixing devices for lithium battery cathode materials use only vibration or rotation to achieve the mixing effect, which results in the cathode material not achieving the best mixing effect after mixing.

[0011] As a further description of the above technical solution: a receiving tank is slidably connected to the top of the tank support plate, and a storage slot is provided inside the receiving tank;

[0012] As a further description of the above technical solution: a rotating groove is provided on the rear inner side of the shaking support plate, the flat gear is rotatably connected in the rotating groove, and the transmission gear is rotatably connected in the rotating groove;

Then, the drive transmission shaft drives the drive working shaft to rotate. Afterwards, the rotational force is transmitted to the spur gear and the shaking support plate through the connecting rod fixed inside the drive working shaft. The rotation of the shaking support plate realizes the shaking of the container, so as to achieve the shaking effect of the positive electrode material. At the same time, the rotating spur gear drives the transmission gear to rotate, and then drives the auxiliary transmission shaft to rotate through the connecting shaft. Then, the auxiliary working shaft and the container support plate are driven to rotate through the belt to ensure that the container is shaken in multiple axes, thereby ensuring the mixing effect of the positive electrode material.

Because of the presence of the electric push rod, the device can adapt to fixing plates of different heights, thereby improving the practicality and stability of the device.
