Flaky coal sample automatic preparation device applied to small-angle X-ray scattering in-situ loading experiment

The invention aims to provide an automatic flaky coal sample preparation device applied to a small-angle X-ray scattering in-situ loading experiment, which is characterized in that the central axes of a sample pressing column driving motor, a cover plate, a sample pressing column, a rubber ring, a sample loading groove and a base are on the same straight line, and the sample pressing column driving motor is mounted on the upper surface of the cover plate; the surface of the sample pressing column is provided with measuring scales. The outer side of the lower end of the sample pressing column is provided with a rubber ring. The sample pressing column is arranged in a sample containing groove. A supporting beam is welded to the outer side of the sample containing groove. The other end of the supporting beam is connected to a supporting column. The upper end of the supporting column is connected with the cover plate. Four rolling shaft driving motors are respectively arranged on the upper surface of the base, ro
