[0002] With the increasing demand for high-performance, long-life lithium-ion batteries from markets such as electric vehicles, portable electronic devices, and energy storage systems, the performance requirements for battery anode materials are becoming increasingly stringent. Lithium-ion composite battery anode materials are typically made from a variety of different raw materials through processes such as mixing, crushing, and grinding to improve their electrochemical performance, conductivity, and cycle stability. In this context, mixing devices are used to uniformly mix the different components of the anode material, ensuring the consistency of each component in terms of particle size, distribution, and chemical reactivity, thereby improving the performance and safety of the final battery and ensuring the high-quality and efficient production of composite battery anode materials.
[0003] Currently, there are various types of mixing devices on the market. However, after running for a long time, material residue usually accumulates on the internal mixing components and inner walls of these devices. Operators often need to manually clean them, which not only increases labor intensity but also affects production efficiency and operational safety to some extent. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a mixing device for lithium-ion composite battery negative electrode materials.
[0005] This utility model is achieved by the following technical solution: a mixing device for lithium-ion composite battery negative electrode material, including a cleaning mechanism, a stirring mechanism and a machine body, wherein the cleaning mechanism is located inside the machine body and the stirring mechanism is located at the bottom of the cleaning mechanism; The cleaning mechanism includes a protective shell, inside which a blower assembly is installed. A control button is fixedly connected to the surface of the blower assembly. A connecting plate is slidably connected to the side of the protective shell near the control button. A base plate is fixedly connected to the bottom of the connecting plate. An extension plate is fixedly connected to the surface of the connecting plate. A ring is fixedly connected to the outer side of the extension plate. A sliding plate is fixedly connected to the surface of the ring.
[0006] Through the above technical solution, the ring rotates to drive each extension plate to move synchronously, thereby driving multiple blower components to operate simultaneously, enabling the blower components to work collaboratively at a unified rhythm.
[0007] As a further improvement to the above solution, the protective shell is located inside the ring, and the base plate is located at the bottom of the protective shell.
[0008] As a further improvement to the above solution, the stirring mechanism includes a drive motor, the output end of which is fixedly connected to a connecting shaft, and the bottom of the connecting shaft is fixedly connected to a stirring assembly.
[0009] Through the above technical solution, the drive motor drives the stirring component to rotate through the connecting shaft, which effectively improves the overall working efficiency of the device and increases the mixing uniformity.
[0010] As a further improvement to the above solution, the machine body includes a housing, with a feed inlet fixedly connected to one side of the housing and a discharge outlet fixedly connected to the other side of the housing.
[0011] The above technical solutions not only facilitate the addition and output of materials through the inlet and outlet, but also prevent blockage or overflow during the mixing process, making the entire device run more smoothly in the production process.
[0012] As a further improvement to the above solution, the number of protective shells is set to four, and the four protective shells are distributed equidistantly around the shell as the center, and the bottom of the protective shell is fixedly connected to the inner wall of the shell.
[0013] Through the above technical solution, the equidistantly distributed protective shells can provide effective protection for each blower component, further ensuring its safety.
[0014] As a further improvement to the above solution, the surface of the base plate is slidably connected to the inner wall of the housing, and the slide plate is located on the outer side of the housing.
[0015] As a further improvement to the above solution, the stirring assembly is located inside the housing, and the protective shell is located at the upper end of the stirring assembly.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a cleaning mechanism where the operator rotates a ring by sliding a sliding plate. The rotation of the ring then drives the extension plate to move, which in turn moves the base plate via a connecting plate. This causes the base plate to move away from the bottom of the protective shell. Simultaneously, the movement of the connecting plate eliminates the need to press the control button, allowing it to be released and activating the air blowing assembly. The air blowing assembly blows air into the shell, causing materials adhering to the mixing assembly and the inner wall of the shell to be blown towards the bottom of the shell. This device achieves automated air blowing cleaning, saving labor costs and preventing the accumulation of residual materials from interfering with subsequent mixing operations, thus further improving overall work efficiency.
[0017] This invention utilizes the cooperation between the stirring mechanism and the machine body. The operator puts the material into the shell through the feed port, and then the drive motor drives the stirring component to rotate through the connecting shaft, thereby ensuring uniform mixing of the material. The mixed material can finally be conveyed out through the discharge port, thus meeting the needs of efficient production. Attached Figure Description

[0021] Example
[0022] Please combine Figure 1-6 The mixing device for lithium-ion composite battery negative electrode material in this embodiment includes a cleaning mechanism 1, a stirring mechanism 2 and a body 3. The cleaning mechanism 1 is located inside the body 3 and the stirring mechanism 2 is located at the bottom of the cleaning mechanism 1. The cleaning mechanism 1 includes a protective shell 11, inside which a blower assembly 12 is installed. A control button 13 is fixedly connected to the surface of the blower assembly 12. A connecting plate 14 is slidably connected to the side of the protective shell 11 near the control button 13. A base plate 15 is fixedly connected to the bottom of the connecting plate 14. An extension plate 16 is fixedly connected to the surface of the connecting plate 14. A ring 17 is fixedly connected to the outer side of the extension plate 16. A slide plate 18 is fixedly connected to the surface of the ring 17. The ring 17 rotates to drive each extension plate 16 to move synchronously, thereby driving multiple blower assemblies 12 to operate simultaneously, so that the blower assemblies 12 can work together in a unified rhythm.
[0023] The protective shell 11 is located inside the ring 17, and the base plate 15 is located at the bottom of the protective shell 11.
[0024] The stirring mechanism 2 includes a drive motor 21, the output end of which is fixedly connected to a connecting shaft 22, and the bottom of the connecting shaft 22 is fixedly connected to a stirring component 23. The drive motor 21 drives the stirring component 23 to rotate through the connecting shaft 22, which effectively improves the overall working efficiency of the device and increases the mixing uniformity.
[0025] The machine body 3 includes a shell 31. A feed inlet 32 is fixedly connected to one side of the shell 31, and a discharge outlet 33 is fixedly connected to the other side of the shell 31. The feed inlet 32 and the discharge outlet 33 not only facilitate the addition and output of materials, but also prevent blockage or overflow during the mixing process, making the entire device run more smoothly in the production process.
[0026] There are four protective shells 11, which are equidistantly distributed around the housing 31. The bottom of the protective shell 11 is fixedly connected to the inner wall of the housing 31. The equidistantly distributed protective shells 11 can provide effective protection for each blower component 12, further ensuring its safety.
[0027] The surface of the base plate 15 is slidably connected to the inner wall of the housing 31, and the slide plate 18 is located on the outside of the housing 31.
[0028] The stirring assembly 23 is located inside the housing 31, and the protective shell 11 is located at the upper end of the stirring assembly 23.
[0029] The implementation principle of the mixing device for lithium-ion composite battery negative electrode material in this embodiment is as follows: The operator slides the slide plate 18, which drives the ring 17 to rotate, thereby moving the internal extension plate 16. The moving extension plate 16 then drives the bottom plate 15 to move synchronously via the connecting plate 14, allowing the bottom plate 15 to move away from the bottom of the protective shell 11. At this time, the connecting plate 14, moving outward, releases the pressure on the control button 13, and the control button 13 drives the blowing assembly 12 to start operating. The blowing assembly 12 continuously blows air into the interior of the shell 31. Meanwhile, the drive motor 21 drives the stirring assembly 23 to rotate via the connecting shaft 22, allowing the blowing assembly 12 to fully blow air onto the stirring assembly 23, blowing the material attached to the stirring assembly 23 towards the bottom of the interior of the shell 31, thus cleaning the stirring assembly 23. After cleaning, the operator slides the slide plate 18 in the opposite direction to drive the ring 17 to rotate, causing the extension plate 16 to move along with the connecting plate 14. The movement of the control button 13 causes it to be pressed again, which stops the blower assembly 12. At this time, the base plate 15 slides back to the bottom of the protective shell 11, effectively protecting the blower assembly 12. The rotation of the slide plate 18 drives the ring 17 to rotate, which in turn drives the extension plates 16 to move synchronously, thus achieving synchronous operation of the blower assemblies 12. The operator puts the material into the shell 31 through the feed port 32 and starts the drive motor 21 by connecting the external power supply. The drive motor 21 drives the stirring assembly 23 to rotate through the connecting shaft 22, thereby achieving full stirring of the material and making it evenly mixed. After mixing, the material is conveyed out through the discharge port 33. The entire device can effectively clean the stirring assembly 23 and the inner wall of the shell 31 through the blower assembly 12, thereby blowing off the material adsorbed on its surface. This eliminates the need for manual cleaning by the operator, further reducing the labor intensity of the operator and making better use of resources.
[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
