Zusammenfassung:	The utility model belongs to the technical field of powder spreading devices, particularly relates to a selective laser sintering polystyrene forming double-roller powder spreading device, and provides the following scheme aiming at the problems that the powder spreading device is inconvenient to screen powder, powder particles are not uniform and normal use is influenced, the selective laser sintering polystyrene forming double-roller powder spreading device comprises a mounting seat, and a mounting vertical hole is formed in the mounting seat; a working cylinder is fixedly mounted in the mounting vertical hole, L-shaped plates are slidably mounted on the two sides of the mounting seat, a same moving seat is fixedly mounted on one sides of the two L-shaped plates, a powder groove is formed in the top of the moving seat, a powder outlet groove communicated with the powder groove is formed in the bottom of the moving seat, and two flattening rollers are rotatably mounted in the powder outlet groove. And a firs
