▎ 摘　　要

NOVELTY - The system has a slider (62) which is slidably mounted on the bottom of two parallel crossbars (61). The slider is controlled to slide by a push rod (63) mounted on an inner wall of a casing (1). A roller (64) is arranged on the top of two parallel crossbars. The middle portion of the roller is provided with a mounting block (65). The bottom of the mounting block is connected to the slider by a spring. The top of the mounting block supports a placing vessel (67) through a set of telescopic rods (66). The roller is capable of rolling on the crossbar. Multiple grooves are arranged on the top of the two crossbars and form a zigzag shape. The groove is provided with a baffle plate (69) on the side. The roller is tilted, and baffle plate is allowed to block the end of the roller, when one end of the roller falls into grooves. USE - Graphene preparation system. ADVANTAGE - The vibration of the swing module is utilized to avoid the accumulation of raw materials and affect the generation of graphene. The graphite particles are prevented from being locally deposited in the storage vessel, and the clogging of the feed hopper is avoided, by setting the vibration module. The graphite particles are shaken in the placing dish to avoid the accumulation of raw materials and affect the generation of graphene, by setting the shaking module. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene preparation system.
