[0002] In the new energy lithium battery industry, cathode raw materials are the core components that determine the battery's energy density, cycle life, and safety performance. Their quality stability and consistency directly affect the finished product quality of lithium batteries. These cathode raw materials mostly exist in powder form and require multiple processes such as raw material mixing, sintering, crushing, and sieving during production. Furthermore, precise sampling and testing are necessary before storage, transportation, and feeding into the battery cells to ensure the production quality of lithium batteries.

[0003] During the sampling process, auger-type samplers may experience material overflow or the introduction of foreign objects due to sealing problems. This not only affects the accuracy of the sampling and testing data, but some materials may also have an impact on human health and the working environment. In view of the above reasons, this application proposes a powder material sampler. Utility Model Content

The rod 2 is equipped with a double-layer sealing O-ring 3, and a sampling groove with a 70mm interval is provided between the double-layer sealing O-ring 3. The sampling groove is used to collect materials. The feed pipe 8 and the discharge pipe 7 are connected by threads. The sealing cover 9 and the sampling tube 1 are connected by threads. The bottom of the sampling tube 1 is equipped with the discharge pipe 7, and the bottom of the discharge pipe 7 is movably equipped with the feed pipe 8. One end of the sampling tube 1 is movably equipped with the sealing cover 9. The sealing cover 9, the feed pipe 8 and the double-layer sealing O-ring 3 achieve a triple seal for the sampler, which can effectively prevent foreign objects from entering the sampler and prevent material from overflowing.

[0039] Combination Figure 4As shown, the bottom inner wall of the discharge pipe 8 is provided with multiple cleaning components 12. The cleaning components 12 are used to scrape off the powder residue on the inner wall of the discharge pipe 7 to avoid cross-contamination caused by material residue and ensure the measurement accuracy of the sampling data. The cleaning components 12 include an installation cylinder 121, a column 124 is movably installed inside the installation cylinder 121, and a guide cover 130 is fixedly installed on the outside of the column 124. The guide cover 130 is umbrella-shaped and can prevent powder material from falling into the holes on the installation cylinder 121 and the column 124, ensuring that the installation cylinder 121 and the column 124 can be easily disassembled and assembled. At the same time, it can also ensure that it does not mix with the participating materials during the next material collection, ensuring the accuracy of the test. The inner wall of the installation cylinder 121 is provided with positioning holes 123 and two A limiting groove 122 is provided. Two limiting blocks are fixedly provided on the outside of the column 124. The limiting blocks and the limiting groove 122 are movably connected. A positioning rod 128 is movably provided inside the column 124. The positioning rod 128 is adapted to the positioning hole 123. A storage hole 125 is provided on the outside of the column 124. A spring 126 is fixedly provided inside the storage hole 125. A guide plate 127 is fixedly provided at one end of the spring 126. The guide plate 127 is movably connected to the storage hole 125. The side of the guide plate 127 away from the spring 126 is fixedly connected to the positioning rod 128. Press the positioning rod 128 to retract it into the storage hole 125. Then pull the column 124 upward to separate the column 124 from the mounting cylinder 121 and complete the disassembly of the column 124.

[0040] Reference Figures 1-4 As shown, a mounting plate 129 is fixedly provided on one side of the column 124. A brush bristle is arranged on one side of the mounting plate 129. The brush bristle is in contact with the inner wall of the discharge pipe 7. When the discharge pipe 8 is rotated off, the brush bristle can scrape off the material attached to the inner wall of the discharge pipe 7, avoiding cross-contamination caused by material residue and ensuring the measurement accuracy of the sampling data.

[0041] In this embodiment, the sealing cap 9, the discharge pipe 8, and the double-layer sealing O-rings 3 achieve a triple seal for the sampler, effectively preventing foreign objects from entering the sampler and preventing material overflow. During sampling, first open the sealing cap 9 and push the pull rod 2 towards the hopper. At this time, the push plate 5 at one end of the pull rod 2 slides along the inner wall of the sampling pipe 1, pushing the residual material from the previous batch back into the hopper, reducing material waste. Continue pushing the pull rod 2 until the sampling groove, with a 70mm gap between the double-layer sealing O-rings 3, is fully inserted into the material flow. The powder material naturally fills the sampling groove. The double-layer sealing O-rings 3 can isolate external contamination, ensuring sample purity. Pull the pull rod 2 in the opposite direction until the sampling groove is aligned with the discharge pipe 7 at the bottom of the sampling pipe 1. Then, rotate to open the discharge pipe 7 at the bottom. Material in the sampling trough falls into the discharge pipe 8 along the discharge pipe 7. Finally, the discharge pipe 8 is rotated to separate it from the discharge pipe 7, and the material is then introduced into the sampling bag to complete the sampling. When the discharge pipe 8 is unscrewed, its inner wall cleaning component 12 works simultaneously. The bristles on one side of the column 124 are attached to the inner wall of the discharge pipe 7 and scrape off residual material as the discharge pipe 8 moves to avoid cross-contamination. If it is necessary to clean the bristles deeply, press the positioning rod 128 to retract it into the storage hole 125 and compress the spring 126. Then pull the column 124 along the limiting groove of the mounting cylinder 121 to complete the disassembly. The umbrella-shaped guide cover 130 outside the column 124 can prevent powder from getting stuck in the parts. After sampling, push the pull rod 2 back to the starting position, tighten the sealing cover 9 and the discharge pipe 8, and restore the equipment to the sealed state.

[0042] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
