Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, and in particular to a conveying and stirring drum for lithium batteries. Background Technology

[0002] In recent years, with the rapid development of the global new energy industry, especially the explosive growth of the new energy vehicle market, stringent requirements have been placed on the performance and production capacity of lithium batteries. In the production process of lithium batteries, the stirring and conveying process is crucial and directly affects the quality and production efficiency of lithium batteries.

[0003] In terms of mixing, most methods use simple single-shaft mixing devices. Single-shaft mixing can only turn the material over within a limited range, making it difficult to form a comprehensive and complex material flow state, resulting in uneven mixing. For the high-precision material ratio required for lithium battery production, this uneven mixing can easily lead to inconsistent battery performance and a high defect rate. Therefore, we propose a conveying and mixing drum for lithium batteries to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a conveying and stirring cylinder for lithium batteries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveying and stirring drum for lithium batteries includes: a stirring drum body, a top cover detachably mounted on the top of the stirring drum body, a frame fixedly mounted on the top of the top cover, a rotating shaft rotatably mounted inside the frame, a bevel gear one and a bevel gear two fixedly mounted on the outer side of the rotating shaft, two sets of stirring shafts rotatably mounted inside the top cover, multiple sets of stirring blades fixedly mounted on the outer side of each of the two sets of stirring shafts, a bevel gear three fixedly mounted on the top of each of the two sets of stirring shafts, a feed pipe connected to one side of the stirring drum body, a feed box connected to one end of the feed pipe, a stirring rod rotatably mounted inside the feed box, a discharge pipe connected to the discharge port of the stirring drum body, a conveying box connected to the bottom of the discharge pipe, an auger rotatably mounted inside the conveying box, and a discharge pipe connected to the bottom of the conveying box.

[0007] Preferably, a support frame is fixedly installed on the outer side of the mixing drum body, three sets of support legs are fixedly installed at the bottom of the support frame, two sets of support plates are fixedly installed at the bottom of the feeding box, connecting flanges are fixedly installed on the outer side of the discharge port of the mixing drum body and the outer side of the feeding pipe, and the discharge port of the mixing drum body and the feeding pipe are connected by connecting flanges. A motor is fixedly installed on one side of the feeding box, and one end of the stirring roller is fixedly installed on the output end of the motor.

[0008] Preferably, a motor is fixedly installed on one side of the frame, and one end of the rotating shaft is fixedly installed on the output end of the motor.

[0009] Preferably, bevel gear one and bevel gear two are respectively meshed with corresponding bevel gear three, and bevel gear one, bevel gear two and bevel gear three are all disposed in the frame, and bevel gear one and bevel gear two are in opposite directions.

[0010] Preferably, a second motor is fixedly installed on one side of the conveying box, and one end of the auger is fixedly installed on the output end of the second motor.

[0011] Preferably, the top of the top cover has two sets of rotating holes, and the two sets of stirring shafts are rotatably installed in the corresponding rotating holes.

[0012] In this utility model, a conveying and stirring drum for lithium batteries is provided with a support frame on the outside of the stirring drum body and a support leg at the bottom of the support frame, thereby ensuring the stability of the stirring drum body during the stirring process. Two sets of support plates are provided at the bottom of the conveying box, thereby ensuring the stability of the conveying box during the conveying process, laying a good foundation for subsequent lithium battery production processes.

[0013] This utility model features a reasonable structural design. A third motor drives the stirring rollers to agitate the material in the feeding box, preventing material blockage during feeding. The material is then conveyed into the mixing drum body through the feeding pipe, quickly adding it in. A first motor drives the rotating shaft, bevel gear one, and bevel gear two to rotate. Since bevel gear one and bevel gear two mesh with bevel gear three at the top of the corresponding two sets of stirring shafts, they rotate in opposite directions. This causes the two sets of stirring shafts to rotate in opposite directions under the transmission of bevel gear three. The two sets of stirring shafts then drive the corresponding stirring blades to agitate the lithium battery material bidirectionally. The discharge pipe is connected to the bottom of the mixing drum body via a connecting flange, transferring the material to the conveying box. The second motor then drives the auger to convey the mixed material to the discharge pipe, where it is quickly discharged for the next production process. This effectively improves the mixing quality of the lithium battery slurry, thereby enhancing the performance consistency of the lithium battery, meeting the demand for rapid material supply in large-scale production, ensuring timely mixing, and improving overall production efficiency.

[0019] Reference Figure 1-3 A mixing drum for conveying lithium batteries includes: a mixing drum body 1, a top cover 2 detachably mounted on the top of the mixing drum body 1, a frame 6 fixedly mounted on the top of the top cover 2, a rotating shaft 17 rotatably mounted inside the frame 6, a bevel gear 18 and a bevel gear 29 fixedly mounted on the outer side of the rotating shaft 17, two sets of stirring shafts 15 rotatably mounted inside the top cover 2, multiple sets of stirring blades 16 fixedly mounted on the outer side of each of the two sets of stirring shafts 15, a bevel gear 3 20 fixedly mounted on the top of each of the two sets of stirring shafts 15, a feed pipe 3 connected to one side of the mixing drum body 1, a feed box 21 connected to one end of the feed pipe 3, a stirring rod 23 rotatably mounted inside the feed box 21, a discharge pipe 8 connected to the discharge port of the mixing drum body 1, a conveying box 10 connected to the bottom of the discharge pipe 8, an auger 13 rotatably mounted inside the conveying box 10, and a discharge pipe 12 connected to the bottom of the conveying box 10.

[0020] In this embodiment, a support frame 4 is fixedly installed on the outer side of the mixing drum body 1, and three sets of support legs 5 are fixedly installed at the bottom of the support frame 4. Two sets of support plates 14 are fixedly installed at the bottom of the feeding box 10. A connecting flange 9 is fixedly installed on the outer side of the discharge port of the mixing drum body 1 and the outer side of the feeding pipe 8. The discharge port of the mixing drum body 1 and the feeding pipe 8 are connected through the connecting flange 9. A motor 22 is fixedly installed on one side of the feeding box 21, and one end of the stirring roller 23 is fixedly installed on the output end of the motor 22 to reduce displacement and shaking caused by vibration during the mixing process, and ensure that the mixing work can be carried out smoothly and continuously.

[0021] In this embodiment, a motor 7 is fixedly installed on one side of the frame 6, and one end of the rotating shaft 17 is fixedly installed on the output end of the motor 7, which improves the energy utilization efficiency of the entire stirring system and reduces energy consumption.

[0022] In this embodiment, bevel gear 18 and bevel gear 29 mesh with the corresponding bevel gear 30. Bevel gear 18, bevel gear 29 and bevel gear 30 are all set in the frame 6. The directions of bevel gear 18 and bevel gear 29 are opposite, which greatly improves the uniformity of material mixing and helps to improve the quality of slurry and other materials in lithium battery production, thereby ensuring the performance and quality of lithium batteries.

[0023] In this embodiment, a motor 2 11 is fixedly installed on one side of the material conveying box 10, and one end of the auger 13 is fixedly installed at the output end of the motor 2 11 to avoid material accumulation or insufficient supply, thereby improving production efficiency and continuity.

Then, the material is transported into the mixing drum body 1 through the feed pipe 3. The motor 7 is started to drive the rotating shaft 17, bevel gear 18 and bevel gear 29 to rotate. Since bevel gear 18 and bevel gear 219 are respectively engaged with bevel gear 20 at the top of the two sets of stirring shafts 15, the bevel gear 18 and bevel gear 219 are driven to rotate relative to each other. This causes the two sets of stirring shafts 15 to rotate in opposite directions under the action of bevel gear 20. Then, the two sets of stirring shafts 15 drive the corresponding stirring blades 16 to stir the lithium battery material in both directions, which effectively improves the mixing quality of the lithium battery slurry and thus improves the performance consistency of the lithium battery.

The material is quickly discharged from the discharge pipe 12 and conveyed to the next production process.

[0027] By setting a support frame 4 on the outside of the mixing drum body 1 and setting a support leg 5 at the bottom of the support frame 4, the stability of the mixing drum body 1 during the mixing process is ensured. By setting two sets of support plates 14 at the bottom of the material conveying box 10, the stability of the material conveying box 10 during the material conveying process is ensured.
