Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, and in particular relates to a lithium battery material powder spreading device. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium as the battery material. They are widely used in electronic products such as mobile phones, laptops, and electric vehicles. Their advantages include high energy density, long service life, light weight, and low self-discharge rate. Lithium-ion battery material powder spreading equipment usually refers to equipment used in the lithium-ion battery manufacturing process to evenly spread certain powdered materials onto a specific area or workpiece surface. This equipment plays an important role in the production process of lithium-ion batteries, especially in the distribution and processing of powdered raw materials such as positive and negative electrode materials, conductive materials, or additives.

[0003] Existing lithium battery material powder dispensing devices typically dispense powder directly into the material after mixing, which may cause the powder to adhere to the inner wall of the device. If the device can vibrate during the dispensing process to shake off the powder adhering to the inner wall, more powder can be incorporated into the mixing process. Therefore, we propose a lithium battery material powder dispensing device. Utility Model Content

At this time, the second offset shaft drives the moving bar to perform a reciprocating motion, causing the moving bar to drive the moving plate to reciprocate within the feeding shell. When the first inlet on the moving plate aligns with the second inlet on the fixed plate, the powder will fall into the mixing device through the fixed plate and the second inlet. The moving bar, which can drive the moving plate to perform a reciprocating motion, allows for gradual feeding, resulting in a more uniform mixing of the powder and materials.

[0028] One specific application of this embodiment is: When staff need to use the equipment, they can start the motor 211, and then process the powder through the feeding shell 103. Finally, the powder will enter the mixing device 102 and be mixed with the materials. It should be stated here that the mixing device 102 in this application is prior art and will not be described in detail here. Its internal structure is similar to the internal structure of the mixing tank in a lithium battery material mixing device with publication number CN221965088U. It drives the built-in motor to work through the electric motor, thereby driving the stirring mechanism to rotate for stirring and mixing. When the powder is added into the feeding shell 103, the motor 211 drives the rotating shaft 212 to rotate, which in turn drives the mixing vane 209 to rotate within the feeding shell 103, thus performing preliminary mixing of the powder. At this time, the rotating shaft 212 also drives the first pulley 213 to rotate. Then, the first pulley 213 drives the second pulley 214 to rotate via the first belt 220, which in turn drives the second gear 216 to rotate. The second gear 216 then drives the first gear 215 to rotate, which in turn drives the first rotating rod 202 to rotate. Then, the first rotating rod 202 drives the first turntable 203 located at both ends of it to rotate, which in turn drives the first offset shaft 204 to perform circular motion on the first turntable 203. At this time, the first off-axis 204 will drive the connecting rod 205 to move, so that the connecting rod 205 drives the moving block 207 to move through the connecting shaft 206. At this time, the moving block 207 will also drive the two limit blocks 218 to slide along the fixed rod 219. Finally, the moving block 207 will drive the rubber block 208 to continuously contact the outer surface of the dispensing shell 103, so that the dispensing shell 103 vibrates. This achieves the effect of making the device vibrate during the powder dispensing process, shaking off the powder adhering to the inner wall of the device. At the same time, the rotating shaft 212 will also drive the fourth pulley 315 to rotate. Then the fourth pulley 315 will drive the third pulley 313 to rotate through the second belt 314. After that, the third pulley 313 will drive the fourth rotating rod 312 to rotate, so that the fourth rotating rod 312 will drive the worm gear 311 to rotate. Then the worm gear 311 will drive the worm wheel 310 to rotate, so that the worm wheel 310 will drive the third rotating rod 302 to rotate. Then, the third rotating rod 302 will drive the second rotating disk 303 to rotate, and the second rotating disk 303 will drive the second off-axis 304 to perform circular motion. At this time, the second off-axis 304 will drive the moving bar 305 to perform reciprocating motion, so that the moving bar 305 drives the moving plate 306 to reciprocate within the feeding shell 103. When the first feed port 307 on the moving plate 306 is aligned with the second feed port 309 on the fixed plate 308, the powder will fall into the mixing device 102 through the fixed plate 308 and the second feed port 309, achieving the effect of gradually adding materials and making the powder and materials more uniformly mixed.
