Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium-ion battery binder production technology, specifically to a mixing and blending equipment for lithium-ion battery binders. Background Technology
[0002] The reference patent, titled "A Device for Stirring Lithium-ion Battery Adhesive" (Authorization Announcement No.: CN211936785U, Authorization Announcement Date: 2020.11.17), includes a stirring tank, a feeding pipe, and a stirring device. Specifically, the feeding pipe is positioned on the bearing surface of the stirring tank and communicates with it. The stirring device is installed inside the stirring tank. Auxiliary materials are added to the stirring tank through the feeding pipe. The stirring device stirs the adhesive and auxiliary materials within the stirring tank, ensuring that the auxiliary materials flow evenly into the stirring tank and mix thoroughly with the adhesive, thereby reducing stirring time and preventing uneven mixing.
[0003] Based on the above-mentioned documents, in the production process of lithium-ion batteries, the quality of mixing and blending of binders has a significant impact on battery performance. Existing binder mixing and blending equipment typically uses a single mixing method, relying solely on fixed mixing components, which makes it difficult to achieve comprehensive and thorough mixing of the binder. This results in uneven mixing of the binder, affecting the quality of subsequent battery production. Furthermore, in existing equipment, the movement path of materials within the container is relatively fixed during the mixing process, creating mixing dead zones, which further reduces the mixing effect and efficiency. Therefore, this utility model provides a mixing and blending equipment for lithium-ion battery binders. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A mixing and blending device for lithium-ion battery binders includes a base 1, a support 2 and a fixed base 3 fixedly connected to the top of the base 1, and a mixing tank 5 rotated by a reciprocating mechanism 4. The mixing tank 5 is equipped with a mixing and blending mechanism 6, which includes:
[0025] The reciprocating assembly 41 includes an equipment box 411 mounted on the top of the base 1 and a drive motor 412 mounted on the bottom of the base 1. One end of the output shaft of the drive motor 412 is fixedly connected to an eccentric wheel 413 via a coupling. A sliding rod 414 is slidably connected inside the equipment box 411. One end of the sliding rod 414 is fixedly connected to a sliding plate 415. The inner surface of the sliding plate 415 is in contact with the surface of the eccentric wheel 413. One side of the sliding plate 415 causes the mixing tank 5 to rotate via a transmission assembly 7.
[0026] Limiting component 42 is located on the top of base 1 and is used to slide and limit transmission component 7.
[0027] The drive motor 412 is a three-phase asynchronous motor and is connected to an external circuit via wires;
[0028] The eccentric wheel 413 and the sliding plate 415 are both located inside the equipment box 411;
[0029] The sliding rod 414 is used to limit the sliding of the sliding plate 415.
[0030] The eccentric wheel 413 slides on the inner surface of the sliding plate 415. When the eccentric wheel 413 rotates, it will drive the sliding plate 415 to perform reciprocating linear motion.
[0031] In this embodiment, the transmission assembly 7 includes a sliding toothed plate 71 mounted on one side of the sliding plate 415 and a toothed block 72 mounted on the surface of the mixing tank 5, with the surface of the sliding toothed plate 71 meshing with the surface of the toothed block 72.
[0032] By incorporating a reciprocating mechanism 4, the mixing tank 5 is driven by a reciprocating motor to rotate back and forth. This allows for precise positioning of the adhesive within the mixing tank 5, effectively preventing the formation of dead zones in the mixing process. Consequently, the adhesive can be more thoroughly mixed, thereby improving the final quality of the lithium-ion battery adhesive.
[0033] In this embodiment, the limiting component 42 includes a limiting plate 421 installed on the top of the base 1. A limiting groove 422 is formed on the top of the limiting plate 421, and the inner surface of the limiting groove 422 is slidably connected to the bottom of the sliding toothed plate 71.
[0034] During the reciprocating linear motion of the sliding toothed plate 71, the limiting groove 422 at the top of the limiting plate 421 limits and guides the bottom of the sliding toothed plate 71. The setting of the limiting groove 422 ensures that the sliding toothed plate 71 will not deviate during the motion and will always move in the correct direction, thereby ensuring the stable and reliable reciprocating rotation of the mixing tank 5 and improving the overall stability and reliability of the equipment operation.
[0035] In this embodiment, the stirring and mixing mechanism 6 includes a stirring motor 61 installed on one side of the support base 2 and a protective box 62 installed on one side of the fixed base 3. One end of the output shaft of the stirring motor 61 is fixedly connected to a rotating shaft 63 via a coupling. One end of the rotating shaft 63 extends through the interior of the mixing tank 5 and is fixedly connected to a shovel plate 64. Multiple stirring rods 65 are fixedly connected to the surface of the shovel plate 64. One end of the shovel plate 64 is fixedly connected to a connecting shaft 66. The surface of the connecting shaft 66 is rotatably connected to the interior of the fixed base 3. One end of the connecting shaft 66 extends through the interior of the protective box 62 and is fixedly connected to a supporting bevel gear 67. The surface of the supporting bevel gear 67 causes the mixing rod 68 to rotate via a linkage component 8.
[0036] The stirring motor 61 is a three-phase asynchronous motor and is connected to an external circuit via wires;
[0037] Rotating shaft 63 rotates inside mixing tank 5;
[0038] The adhesive at the bottom of the mixing tank 5 can be agitated by rotating the spatula 64, thereby improving the mixing quality of the adhesive.
[0039] In this embodiment, the linkage assembly 8 includes a connecting bevel gear 81 rotatably mounted at the bottom of the inner cavity of the protective box 62 and a linkage rod 82 rotatably mounted inside the connecting shaft 66. The surface of the connecting bevel gear 81 meshes with the surface of the supporting bevel gear 67. The surface of the linkage rod 82 is fixedly connected to the surface of the mixing rod 68. One end of the linkage rod 82 is rotatably connected to the inner wall of the protective box 62. One end of the linkage rod 82 is fixedly connected to a linkage bevel gear 83. The surface of the linkage bevel gear 83 meshes with the surface of the connecting bevel gear 81.
[0040] In this embodiment, the mixing tank 5 rotates inside the support base 2 and the fixed base 3. A feed pipe is installed on the top of the mixing tank 5, and a discharge pipe is installed on the bottom of the mixing tank 5.
[0041] By incorporating a stirring and mixing mechanism 6, multiple sets of stirring rods 65 and mixing rods 68 work together to stir the binder from different directions, improving the uniformity and efficiency of the stirring and ensuring the quality of the mixing and preparation of the lithium-ion battery binder. Furthermore, by incorporating a limiting component 42 to slide and limit the transmission component 7, the stability and reliability of the equipment during operation are ensured, and the service life of the equipment is extended.
[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0043] During operation, various raw materials for the binder are first poured into the mixing tank through the feed pipe at the top of the mixing tank. Then, the drive motor 412 and the stirring motor 61 on one side of the support base 2 are started. The drive motor 412 begins to work, and its output shaft drives the eccentric wheel 413 to rotate. During rotation, the eccentric wheel 413, due to its eccentric structure, continuously pushes the sliding plate 415 to move. The sliding plate 415 is fixedly connected to the sliding rod 414, which slides within the equipment box 411, ensuring that the sliding plate 415 can only perform reciprocating linear motion in a specific direction. A sliding toothed plate 71 is fixedly installed on one side of the sliding plate 415. Driven by the sliding plate 415, the sliding toothed plate 71 also performs reciprocating linear motion. Simultaneously, toothed blocks 72 are provided on the surface of the mixing tank 5. The sliding toothed plate 71 and the toothed blocks 72 mesh with each other. When… When the sliding toothed plate 71 makes reciprocating linear motion, it drives the mixing tank 5 to reciprocate within the support base 2 and the fixed base 3 through the toothed block 72. The reciprocating rotation of the mixing tank 5 causes the binder inside the tank to continuously change position, avoiding the binder from staying in the same area for a long time, thereby effectively eliminating the dead zone of stirring and allowing the binder to move more fully in the tank. On the other hand, after the stirring motor 61 is started, its output shaft drives the rotating shaft 63 to rotate. The rotating shaft 63 passes through the mixing tank 5, and a shovel plate 64 is fixedly connected to one end of the rotating shaft 63. Multiple sets of stirring rods 65 are fixed on the surface of the shovel plate 64. When the rotating shaft 63 rotates, it drives the shovel plate 64 and the stirring rods 65 to rotate in the mixing tank 5 to stir the binder. The stirring rods 65 stir the binder from different angles, initially realizing the mixing of the binder.
[0044] At the same time, the rotation of the rotating shaft 63 will also drive the connecting shaft 66 and the supporting bevel gear 67 to rotate. When the supporting bevel gear 67 rotates, it will drive the connecting bevel gear 81 to rotate. The rotation of the connecting bevel gear 81 will drive the linkage bevel gear 83 and the linkage rod 82 to rotate, which will cause the mixing rod 68 to rotate in the mixing tank 5. The rotation direction of the mixing rod 68 is different from that of the stirring rod 65. The two cooperate with each other to stir and mix the binder from multiple directions, further improving the uniformity and efficiency of the binder mixing.
[0045] After the binder is mixed evenly, turn off the drive motor 412 and the stirring motor 61, open the discharge pipe at the bottom of the mixing tank 5, and discharge the mixed binder for subsequent lithium-ion battery production processes.
