It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite crystals along the axial direction of the fiber and undergoing carbonization and graphitization treatment.

[0003] In the process of processing and using carbon fiber materials, in order to ensure that the carbon fiber has a good use effect, the carbon fiber is usually mixed with other substances for use, so as to complement the effects of different substances and ensure that the practicality of the carbon fiber is optimized. In the process of mixing carbon fiber materials with other substances, in order to ensure the overall performance of the substance formed after mixing, the carbon fiber and other substances have a certain adhesion in the mixing device, and then the carbon fiber mixed material with a certain viscosity is easily attached to the inner wall of the mixing device during the discharge process. The carbon fiber mixed material attached to the inner side of the mixing device is easy to condense on the inner side of the mixing device over a long period of time, reducing the internal space volume of the mixing device. Therefore, in view of the above problems, a raw material mixing device for carbon fiber material molding and processing is proposed. Utility Model Content

[0021] There are two arc plates 13, which are rotated 180° with the axis of the rotating shaft 8 as the center point. The arc plates 13 are in close contact with the inner wall and the bottom of the mixing barrel 1, and the arc plates 13 are in close contact with the scraper 10 near the bottom of the mixing barrel 1, so as to facilitate the stirring and scraping of the mixed raw materials of the carbon fiber materials at the bottom of the mixing barrel 1; there are two scraper rods 10, and the upper and lower ends of the scraper rods 10 are not in the same horizontal plane. The scraper rods 10 are in close contact with the inner wall of the mixing barrel 1 away from the rotating shaft 8, so as to facilitate the scraping of the mixed raw materials of the carbon fiber materials attached to the upper side of the inner wall of the mixing barrel 1 to the bottom; the scraper rods 10 are close to the rotating shaft 8. One side is fixedly connected with a plurality of fixed rods 11 distributed at equal intervals, and the fixed rods 11 fixedly connected to the two scraper rods 10 on the outer side of the rotating shaft 8 are staggered in space, so as to facilitate more uniform mixing and stirring of the inner side of the mixing barrel 1 during the rotation of the scraper rods 10; the horizontal line passing through the axis of the rotating shaft 8 between the arc plates 13 and the horizontal line passing through the axis of the rotating shaft 8 of the two scraper rods 10 are perpendicular to each other on the horizontal plane of space, and the arc plates 13 and the outer side of the rotating shaft 8 are parallel to each other on the same vertical plane, and the plurality of stirring rods 12 distributed at equal intervals are parallel to each other, which can enhance the mixing efficiency of the raw material mixing device.

[0022] Working process: During use, the equipment is powered by an external power supply, and the raw materials for processing carbon fiber materials are poured into the inner side of the mixing barrel 1 through the feed hopper 2, and then the valve 5 inside the discharge port 4 is ensured to be in a closed state, and the motor 7 is started. The main shaft of the motor 7 drives the rotating shaft 8 to rotate stably inside the mixing barrel 1 through the bearing 9, and the rotating shaft 8 drives the scraper rod 10, the stirring rod 12 and the arc plate 13 fixedly connected to the outside thereof to rotate inside the mixing barrel 1. While the scraper rod 10 rotates counterclockwise with the rotating shaft 8, the scraper rod 10 close to the inner wall of the mixing barrel 1 continuously scrapes the carbon fiber raw materials attached to the upper side of the inner wall of the mixing barrel 1 to the lower end of the mixing barrel 1.
