▎ 摘　　要

NOVELTY - The device has a distance control mechanism (2) fixed in a machine body (1) and a control mechanism (3). The distance control mechanism is provided with a crucible (22) and a supporting table (213). The crucible is located at a lower end of the machine body. A separating plate (31) is slidingly matched with a control plate (310). The control plate controls opening size of an opening. The crucible is ensured to move upward direction. The supporting table and the control plate are driven to move close to each other. USE - Vacuum coating device for preparing graphene far infrared ceramic. ADVANTAGE - The average thickness of each part of the graphene plated layer is the same, so that the ceramic has good integral effect and use effect. The graphene steam generated on the crucible is increased and diffused, it can just cover the surface of the ceramic, the use rate of graphene contained in the steam is high, and the impact force of the steam passing through the opening is kept to be average, so as to keep the graphene in the through hole of each position of the relative average, ensuring good use effect of graphene far infrared ceramic, improving the quality of graphene Far infrared ceramic preparation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of a vacuum coating device for preparing graphene far infrared ceramic. 1Machine body 2Distance control mechanism 3Control mechanism 11Supporting leg 12Support frame 13Top cover 21Hydraulic rod 22Crucible 23Connecting column 26Rack 27Fixing frame 29Toothed belt 31Separating plate 34Fixing block 213Supporting platform 310Control plate 313Pull rope
