[0029] Specifically, in the process of grinding the graphene powder, first, the graphene powder is poured into the device through the feeding port 3104, then the graphene powder is conveyed by the conveying pipe 29, and finally the powder is discharged into the inside of the feeding port 3 through the discharge port 3105. The graphene powder is further conveyed into the inside of the grinding box 2 through the feeding port 3, and is ready for grinding operation. After the first motor 7 is started, the first motor 7 drives the driving wheel 8 connected to the output end to rotate. The driving wheel 8 drives the driven wheel 10 connected thereto to rotate through the belt 9. When the driving wheel 8 rotates, it further drives the rear rotating rod 27 connected inside it to rotate. The rear rotating rod 27 is connected with the right side spur gear 12 fixed outside it. When the rear rotating rod 27 rotates, it drives the front side spur gear 12 connected thereto to rotate synchronously through meshing. The synchronous rotation of the two spur gears 12 drives the two transmission rods 17 fixed outside to rotate further, and drives the two grinding rollers 13 outside to rotate relatively, so as to grind the graphene powder entering the grinding box 2. Through the relative rotation of the grinding rollers 13, the graphene powder is fully ground under the action of mechanical force. The ground powder falls from below the grinding roller 13 to the upper part of the screening plate 15. At the same time, when the driving wheel 8 rotates, the driven wheel 10 also rotates synchronously. The rotation of the driven wheel 10 drives the transmission rod 17 inside it to rotate inside the mounting shell 18. The rotation of the transmission rod 17 further drives the half gear 19 fixed outside the two sides to rotate. The rotation of the two half gears 19 drives the two rack plates 20 meshed outside to move downward. The downward movement of the rack plate 20 pushes the two fixed rods 26 fixed outside to move downward synchronously, and further drives the bottom screening plate 15 to move downward. When the screening plate 15 moves downward, the guide block 23 connected to the outside of the two sides of the screening plate 15 also moves together, which makes the two return springs 24 fixed on the guide block 23 be stretched. With the stress deformation of the two return springs 24, the rebound force is provided. When the half gear 19 rotates, the meshing between the tooth block and the rack plate 20 will be temporarily separated. At this time, the reaction force of the two return springs 24 pushes the screening plate 15 back up, so as to realize the up-down vibration of the screening plate 15. The continuous action of the up-down vibration effectively screens the ground graphene powder. During the screening process, the graphene powder meeting the requirements will fall through the holes designed on the screening plate 15, enter the upper part of the guide plate 16, and finally be discharged through the first discharge port 4. The graphene powder not meeting the particle size requirements is discharged through the second discharge port 5 under the action of the screening plate 15, so as to be re-ground or processed, so as to effectively separate and classify the graphene powder of different particle sizes, realize the particle size control of the graphene powder, and ensure the particle size consistency of the final product.
[0030] Referring toFigures 2-7 The conveying assembly 31 comprises a second motor 3101 arranged at the lower part of the conveying pipeline 29.

By starting the second motor 3101, the rotating shaft 3102 fixedly connected with the output end rotates inside the conveying pipeline 29, and the spiral conveying blade 3103 fixedly connected outside rotates, thereby conveying the graphene powder. The right side of the outside of the conveying pipeline 29 is fixedly connected with a feeding port 3104, which facilitates the feeding of the graphene powder. The left side of the outside of the conveying pipeline 29 is fixedly connected with a discharge port 3105, which facilitates the discharge of the graphene powder. The lower part of the conveying pipeline 29 is fixedly connected with a fixed ring 30, and the second motor 3101 is fixedly connected inside the fixed ring 30. The fixed ring 30 facilitates the fixation of the second motor 3101.
[0031] Specifically, before the graphene powder is ground, the graphene powder is first placed inside the feeding port 3104. Then, the second motor 3101 is started, and the second motor 3101 drives the fixedly connected rotating shaft 3102 to rotate through the output end. The rotation of the rotating shaft 3102 directly drives the fixedly connected spiral conveying blade 3103. With the rotation of the spiral conveying blade 3103, the graphene powder is orderly pushed along the conveying pipeline 29, realizing continuous conveying of the powder. The spiral conveying blade 3103 generates a spiral conveying force by rotating, gradually pushing the powder from the feeding port 3104 to the discharge port 3105. Finally, the graphene powder smoothly enters the inside of the grinding equipment through the discharge port 3105, starting the subsequent grinding process. This automatic feeding operation can ensure that the graphene powder enters the grinding equipment in a continuous and stable manner, thereby realizing an efficient production process. Compared with the traditional manual feeding method, automatic feeding not only reduces the waiting time in manual operation, but also greatly reduces the possibility of human intervention, reduces errors that may be caused by human operation, and improves production efficiency.
