The utility model relates to a flour-sheet pressing machine. The utility model is characterized in that the utility model is provided with a chain wheel (1) fixed on a shaft end on one end of a fixed compression roller (15), a chain wheel (2) fixed on one end of an adjusting compression roller (14), and a chain (3) through which the chain wheel (1) is sheathed and a chain wheel (4) which is fixed on an oscillating rod fixed with a fixed frame (12) is simultaneously sheathed. The single side of the chain (3) is bypassed from the chain wheel (2); a handle shaft (5) is connected with a crank (6) connected with a connecting rod (8) whose the other end is connected with one end of an oscillating arm (10); the arm turning position of the oscillating arm (10) is fixed with the shaft phase of the adjusting compression roller (14), and the other end of the oscillating arm (10) is rotationally fixed with the fixed frame (12).
