When an element is referred to as "connected to" another element, it can be directly connected to another element or can exist simultaneously with a middle element. When an element is referred to as "fixedly connected to" another element, it can be fixedly connected to another element in a common fixed connection manner such as welding or bolt connection or adhesive connection. In any case, the specific meanings of the above terms in the utility model can be understood by the person skilled in the art according to the specific circumstances.

[0023] Example 1, as Figures 1-3As shown, a lithium battery powder unloading anti-blocking device, including a material cylinder 1, the bottom of the material cylinder 1 is provided with an unloading base 2, the middle of the unloading base 2 is provided with an unloading pipe 3, the unloading pipe 3 is installed with a corresponding butterfly valve, after opening the butterfly valve, the lithium battery powder in the material cylinder 1 will be put into the processing equipment at the rear end from the unloading pipe 3. The inner side of the unloading base 2 is provided with an elastic mechanism, the elastic mechanism includes an outer ring 4, an inner ring 5 and an elastic pad 6, the outer ring 4 is connected with the outer side edge of the unloading base 2, the inner ring 5 is connected with the side edge of the unloading pipe 3, the inner side of the elastic pad 6 is connected with the outer side edge of the inner ring 5, the outer side of the elastic pad 6 is connected with the inner side edge of the outer ring 4, the outer ring 4, the inner ring 5 and the elastic pad 6 form a circular truncated cone structure. The bottom of the lithium battery powder in the material cylinder 1 is accumulated on the elastic pad 6, and slides off from the elastic pad 6 into the inner ring 5 and from the inner ring 5 into the unloading pipe 3. Due to the elasticity and inclination angle of the elastic pad 6, the powder can more easily slide into the inner ring 5 and then into the unloading pipe 3. This dynamic sliding mechanism effectively reduces the accumulation of powder at the bottom, thereby reducing the risk of blockage.

[0024] In combination Figure 4 , the bottom of the unloading base 2 is provided with two mounting holes 7, the mounting holes 7 are connected with a vibration driving mechanism, the vibration driving mechanism includes a vibration motor 8, the output end of the vibration motor 8 is connected with a spherical beating rubber 9, the spherical beating rubber 9 is closely arranged on the elastic pad 6, by starting the vibration motor 8, the spherical beating rubber 9 constantly beats the elastic pad 6, so that the elastic pad 6 vibrates. This vibration effect can further promote the loosening and sliding of the lithium battery powder at the bottom of the material cylinder 1, effectively preventing the accumulation and blockage of the powder. Even in the case of high humidity or strong adhesion between particles, the unloading flow can also be kept smooth, the vibration effect not only helps to prevent blockage, but also speeds up the flow speed of the powder, so that the powder can pass through the unloading pipe 3 into the rear-end processing equipment more quickly. This improves the efficiency of the entire production process and reduces the waiting time. The elastic pad 6 can be made of high molecular materials such as polyvinyl chloride and polytetrafluoroethylene, or soft materials made by textile process.

[0025] In combination Figure 1The inside of the material cylinder 1 is provided with a stirring assembly, the top of the material cylinder 1 is provided with a stirring motor 12, the output end of the stirring motor 12 is connected downwardly with a stirring shaft 13, both sides of the stirring shaft 13 are provided with connecting rods 14, and the connecting rods 14 are connected with square stirring blades 15. The stirring assembly can continuously stir the lithium battery powder inside the material cylinder 1, break the agglomeration and caking of the powder, and keep the powder in a loose state. This continuous stirring action greatly improves the flowability of the powder and reduces the risk of accumulation and blockage of the powder at the bottom of the material cylinder 1. In addition, the stirring action not only improves the flowability of the powder, but also ensures uniform distribution of the powder inside the material cylinder 1. This helps to achieve uniform feeding and avoids the problem of poor feeding or blockage caused by uneven distribution of the powder. The introduction of the stirring assembly enables the device to better adapt to lithium battery powder of different characteristics and states. Whether it is particle size, humidity or adhesion, the stirring action can improve the flowability of the powder to some extent and reduce the risk of blockage.

[0026] The bottom of the stirring shaft 13 is connected with inclined rods 16, the inclined rods 16 are connected with trapezoidal stirring blades 17, the trapezoidal stirring blades 17 can stir the lithium battery powder at the bottom of the material cylinder 1, and further improve the stirring effect. Strengthening the stirring at the bottom helps to reduce the accumulation and caking of the powder at the bottom of the material cylinder 1. This is crucial for preventing blockage and maintaining smooth feeding. The shape and position of the trapezoidal stirring blades 17 enable them to more effectively stir up the powder at the bottom and prevent it from forming a stable accumulation layer.

[0027] Embodiment 2, in combination Figure 5 This embodiment has the same parts as Embodiment 1, and the difference from Embodiment 1 is that the mounting hole 7 is provided with one, the vibration driving mechanism includes an air nozzle 10, one end of the air nozzle 10 is connected with an air pump, the output end of the air nozzle 10 is arranged opposite to the elastic pad 6, and the bottom of the feeding base 2 is further provided with an air outlet hole 11. The airflow generated by the air nozzle 10 directly impacts on the elastic pad 6, causing the elastic pad 6 to vibrate, and the airflow directly acts on the elastic pad 6, which can quickly and effectively induce vibration. This vibration method is direct and efficient, which helps to quickly break up the accumulated powder and prevent blockage. Since the vibration is generated by the airflow impacting the elastic pad 6, there is no direct mechanical contact and wear, thus prolonging the service life of the equipment.

[0028] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
