The invention discloses an integral device for paving and pressing a graphite raw material and extracting a graphite single crystal. The integral device comprises a graphite sheet material producing device and a graphite single crystal preparing device. A special thin graphite sheet is produced, and then a single crystal is separated out by utilizing the thin graphite sheet. In comparison with the prior art, by using the integral device, a graphite powder solution discharged from a graphite dust outlet and an adhesive outlet in a paddle is flatwise paved and pressed; a thin graphite sheet material is formed; the thin graphite sheet material is placed on an interlayer to be heated; the single crystal separated from the sheet material is peeled off in cooperation with a vibrating device; after the thin graphite sheet material is heated at a high temperature, a single crystal layer is more easily separated; the efficiency of extracting the graphite single crystal is higher; the energy consumption is less.
