NOVELTY - The tray has a material tray body (1) that includes a bearing (17) installed in the central shaft groove (161) of the bottom plate (16). A rotating shaft rod (19) is arranged on the bearing. A rotating shaft is arranged on the rotating shaft rod. A material box tray (12) is installed on the top of the rotating shaft rod. A material box cover plate (11) is arranged on the material box tray. A number of support rods (13) are uniformly arranged around the material box tray and the material box cover plate. The strip-shaped slot holes are connected with the matching box. The magazine tray is provided with a number of strip-shaped grooves corresponding to the strip-shaped slot holes. USE - Material tray for facilitating unloading and replacement in a graphene field of a microwave modified device. Uses include but are not limited to lithium of an ion battery negative electrode used as graphite material, graphite is a kind of allotrope of carbon, and grey black, opaque solid comprising natural graphite and artificial graphite. ADVANTAGE - The top end of the material box is provided with a sealing ring, so as to ensure the tightness when connected with the feeding mechanism. The material tray good has the advantages of fast discharging and changing the material boxes.
