[0014] 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.
[0015] Example: Reference Figure 1-4 The graphene electrostatic powder crushing and sieving machine shown includes a placement frame 1, a crushing device 2, and a sieving device. Securely install the placement rack 1, ensuring its load-bearing capacity meets the weight requirements of components such as the crushing device 2 and the screening device. Place the crushing device 2 on the placement rack 1, ensuring that the discharge port of the crushing device 2 is accurately aligned and interconnected with the discharge channel 3 at the bottom of the placement rack 1, guaranteeing smooth material transfer.
[0016] In one embodiment, a screening device is installed at the bottom of the discharge channel 3, ensuring that the inlet of the screening device matches the outlet of the discharge channel 3. The screening cylinder 4 is connected to the conveyor 16 via the bottom plate 5 to ensure effective conveying of the screened material. An annular waste channel 6 is installed on the inner wall of the screening cylinder 4, ensuring that the waste channel 6 is firmly installed and has a complete interconnected structure in its middle. Then, a conical screening screen 7 is installed on the inner wall of the waste channel 6, ensuring that the top edge of the screening screen 7 is flush with the top surface of the waste channel 6, thus ensuring the stability of the basic structure for separating screening and waste.
[0017] In one embodiment, a material feeding mechanism is installed in the middle of the screening screen 7. The mounting plate 12 is fixed to the bottom of the screening screen 7, and the rotating component 8 is rotatably connected to the mounting plate 12. The drive motor 13 is installed at the bottom of the mounting plate 12 and is connected to the rotating component 8 to ensure that the drive motor 13 can drive the rotating component 8 to rotate. Two sets of symmetrical shift plates 9 are installed on the rotating component 8, allowing the shift plates 9 to slide on the screening screen 7. Then, an L-shaped shift component 10 is fixed to the outer end of the shift plate 9 with bolts, completing the assembly of the material feeding mechanism. Simultaneously, a U-shaped support rod 11 is installed on the bottom surface of the mounting plate 12, allowing the support rod 11 to be inserted into the corresponding hole in the screening cylinder 4. The power supply line of the drive motor 13 runs through the inner groove of the support rod 11, enhancing structural stability and optimizing wiring. A waste removal mechanism is installed between the screening cylinder 4 and the waste channel 6. Utilizing the notch 600 on the waste channel 6 and the corresponding notch 400 on the screening cylinder 4, the two are connected by an inclined guide 14. A collection hopper is set below the guide 14 to collect waste. A funnel-shaped collecting hopper 15 is installed below the waste channel 6 and connected to the conveyor 16 to ensure that qualified materials after screening are effectively collected and transported.
[0018] The working principle of this utility model is as follows: Graphene raw material is placed into the crushing device 2, where it is crushed. The graphene then falls onto the screening screen 7 through the discharge channel 3 on the placement frame 1. Simultaneously, the drive motor 13 on the mounting plate 12 is activated, causing the rotating component 8 to rotate on the screening screen 7 and the mounting plate 12. The rotating component 8 drives two sets of baffles 9 on its outer wall to rotate on the screening screen 7, assisting in the screening of the graphene. During this process, larger graphene particles are fed to the outside of the screening screen 7 along the baffles 9, causing larger pieces of graphene to fall into the waste channel 6. Subsequently, the rotating baffles 9, through their ends... The disassembly and installation of the prying part 10 drives the graphene blocks in the waste channel 6 to move, and finally move to the notch 600, and fall from the guide part 14, collecting the block graphene in the collection hopper. The screening cylinder 4 is provided with a notch 400 that matches the notch 600. The height of the notch 400 is lower than the notch. The two work together to tilt the guide part 14 so that the material can fall. After the above screening is completed, the graphene is concentrated and guided through the collection hopper 15 installed on the bottom plate 5 below, so that the graphene enters the conveyor 16 for subsequent loading. The support rod 11 provided at the bottom of the mounting plate 12 is connected to the outside and has a U-shaped structure to facilitate the routing of the line.

[0020] Components not described in detail in this article are existing technologies.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
