Description

Technical Field

[0001] This utility model relates to the field of lithium battery slurry mixing technology, and in particular to a continuous mixing device for lithium battery slurry with anti-accumulation function. Background Technology

[0002] The various raw materials required for lithium battery production, such as active materials, conductive agents, binders, and solvents, are precisely mixed in a certain proportion to ensure that the components in the slurry are evenly distributed, thereby ensuring the consistency and stability of lithium battery performance. Therefore, continuous mixing equipment for lithium battery slurry is needed for mixing and processing.

[0003] In existing technologies, the production of lithium batteries requires mixing of slurries to ensure more complete reactions between the raw materials. Therefore, specialized mixing equipment is required. However, existing mixing equipment is not easy to clean after use. If it is not cleaned for a long time, the inside of the equipment is prone to mold growth and damage, causing inconvenience to the work.

[0004] An existing patent (publication number: CN210522360U) discloses a slurry mixing device for lithium battery production. This device incorporates a cleaning unit on the outside of the mixing drum. An inlet pipe is connected to an external water supply system, and a controller activates a water pump to draw external cleaning water, which is then delivered to the outlet pipe. The water flows through the outlet pipe into a U-shaped pipe and then into a hollow ring. When the water in the hollow ring reaches a certain volume, it is sprayed outwards through the outlet hole. Simultaneously, rotating the handle drives the lead screw to rotate, and the slider slides vertically downwards under the combined action of the lead screw and the sliding groove. The slider also moves the top plate, outlet pipe, U-shaped pipe, and hollow ring downwards, thus enabling the cleaning wires to brush the inner wall of the mixing drum. This, combined with the water sprayed from the outlet hole, effectively cleans the inner wall of the mixing drum quickly, preventing residue from causing corrosion and damage.

[0005] To address the aforementioned issues, while existing patents have proposed solutions that can achieve rapid cleaning through the combination of components such as mixing cylinders, in practical applications, material accumulation during discharge and unloading may occur, leading to blockages or slow flow, thus affecting discharge efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a continuous mixing device for lithium battery slurry that prevents accumulation. This device can agitate the material entering the discharge shell to prevent it from becoming too sticky and accumulating, which would hinder or slow the flow of the material and affect the discharge efficiency. At the same time, it can scrape off the material adsorbed in the collection tank to prevent it from sticking and causing waste. This invention aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuous mixing device for lithium battery slurry with anti-accumulation function, comprising an operating table, a drive motor fixedly installed on one side of the top of the operating table, and a power output end of the drive motor passing through a power housing, a spiral propulsion shaft passing through the front end of the power housing, and a mixing box passing through one end of the spiral propulsion shaft passing through the power housing, and a discharge shell fixedly installed on one side of the bottom of the mixing box, and a pushing mechanism being provided inside the discharge shell;

[0008] The pushing mechanism includes a servo motor, which is embedded in the rear end of the discharge shell, and a drive rod is fixedly installed on the power output end of the servo motor.

[0009] Preferably, a fixing rod is fixedly installed on the outer wall of one end of the drive rod that penetrates into the discharge shell, and an abutment block is slidably connected to the outside of the fixing rod.

A locking ring is fixedly installed at one end of the through rod inside the connecting rod, and a second spring is embedded inside the connecting rod.

[0014] Preferably, a support shaft is fixedly installed on the outer wall of the protruding rod, and a rotating cylinder is rotatably connected to the outer wall of the support shaft, and a pressing block is fixedly installed on the outer wall of the rotating cylinder.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 3 A continuous mixing device for lithium battery slurry with anti-accumulation function includes an operating platform 1. A drive motor 2 is fixedly installed on one side of the top of the operating platform 1. The power output end of the drive motor 2 passes through a power housing 3. A spiral propulsion shaft 4 extends out from the front end of the power housing 3. One end of the spiral propulsion shaft 4, which extends out from the power housing 3, passes through a mixing box 5. A discharge shell 6 is fixedly installed on one side of the bottom of the mixing box 5. A pushing mechanism 7 is provided inside the discharge shell 6. The pushing mechanism 7 includes a servo motor 701, which is embedded in the rear end of the discharge shell 6. The power output end of the servo motor 701 is fixedly installed... A drive rod 702 is fixedly installed. A fixing rod 703 is fixedly installed on the outer wall of one end of the drive rod 702 that passes through the discharge shell 6. An abutment block 704 is slidably connected to the outside of the fixing rod 703. A fixing shell 705 is fixedly installed inside the abutment block 704 at the position corresponding to the fixing rod 703. A first spring 706 is embedded inside the fixing shell 705. A limit ring 707 is fixedly installed on the outer wall of one end of the fixing rod 703 that passes through the fixing shell 705. A storage shell 708 is fixedly installed on one side of the abutment block 704 inside the discharge shell 6. A storage groove 709 is opened inside the storage shell 708.

[0028] By adopting the above technical solution, when the material is conveyed into the discharge shell 6 and accumulates in the collection groove 709 of the collection shell 708, the contact block 704 rotates against the collection groove 709 under the drive of the servo motor 701 and the drive rod 702. At the same time, the first spring 706 inside the fixed shell 705 elastically pushes the fixed rod 703 and is locked by the limit ring 707 to prevent it from disengaging. The elasticity of the first spring 706 allows the contact block 704 to fully adhere to the collection groove 709 and rotate, thereby scraping off the attached material and stirring the conveyed material to maintain its flow state, avoiding the material from being too sticky and accumulating, which would affect the flow efficiency.

[0029] Specifically, such as Figure 2 and Figure 4 As shown, a filter screen 8 is inserted into the interior of the discharge shell 6. An abutment mechanism 9 is provided on one side of the filter screen 8. The abutment mechanism 9 includes a connecting rod 901, which is fixedly installed on one side of the fixing rod 703 on the outer wall of the drive rod 702. A through rod 902 extends out of the interior of the connecting rod 901. A retaining ring 903 is fixedly installed at one end of the through rod 902 inside the connecting rod 901. A second spring 904 is embedded inside the connecting rod 901. A support shaft 905 is fixedly installed on the outer wall of the through rod 902. A rotating cylinder 906 is rotatably connected to the outer wall of the support shaft 905. A pressing block 907 is fixedly installed on the outer wall of the rotating cylinder 906.

[0030] By adopting the above technical solution, the filter screen 8 is inserted into the discharge shell 6 and fixed with bolts to filter and remove impurities from the material, and is easy to disassemble and clean later. At the same time, when the drive rod 702 rotates, it drives the connecting rod 901 to rotate as well. Under the engagement of the locking ring 903, the through rod 902 can be elastically pushed by the second spring 904, so that the rotating cylinder 906 on the outer wall of the support shaft 905 fits against the filter screen 8 and prevents it from falling off. The elasticity of the second spring 904 allows the rotating cylinder 906 to fully fit against the filter screen 8 and rotate without any space, which would prevent the pressing block 907 from being inserted into the gap of the filter screen 8, and may cause the filter screen 8 to become blocked.

[0031] Working principle: Driven by the drive motor 2 embedded in the operating table 1, the two sets of spiral propulsion shafts 4 rotate relative to each other through the cooperation of two gears and one idler wheel inside the power housing 3. This allows the material to be stably and fully pushed and continuously mixed inside the mixing box 5, and finally discharged through the discharge housing 6. This is a conventional technology and will not be described in detail here. The pushed material enters the receiving slot 709 opened in the receiving shell 708 inside the discharge housing 6, and is discharged after impurities are filtered by the detachable filter screen 8. At the same time, through the cooperation of the servo motor 701 and the drive rod 702, the fixed rod 703 drives the contact block 704 to rotate against the inner wall of the receiving slot 709. The first spring 706 embedded inside 05 can prevent the contact block 704 from disengaging from the fixing rod 703 under the limit of the limiting ring 707, and fit tightly against the receiving groove 709. It can scrape off the adsorbed material and stir at the same time to maintain flow and avoid accumulation and blockage. At the same time, the drive rod 702 drives the connecting rod 901 to rotate. The connecting rod 901 is elastically pushed by the second spring 904 to push the through rod 902, and the through rod 902 is prevented from disengaging under the limit of the locking ring 903. During the rotation, the rotating cylinder 906 connected to the outer wall of the support shaft 905 can fully fit against the filter screen 8, and the pressing block 907 can be inserted into the gap of the filter screen 8 to avoid blockage.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
