The invention provides a method for making grain on double sides by suction for artificial leather production. The method is characterized in that the artificial leather wound on a first suction roll and a second suction roll in sequence moves forwards sequentially through the first suction roll and the second suction roll under traction action; one side surface of the artificial leather fits the first suction roll and then grain is made by suction on the side surface of the artificial leather by the first suction roll; the other side surface of the artificial leather fits the second suction roll and then grain is made by suction on the other side surface of the artificial leather by the second suction roll. By the method for making grain on double sides by suction, double-side grain is made during the single manufacturing process, processing procedures are simplified, production efficiency is increased, production cost is lowered, and labor intensity of operation workers is reduced. The invention further provides double-side grain suction-making equipment for artificial leather production; by the double-side grain suction-making equipment, making of double-side grain can be completed during the single manufacturing process, processing procedures are simplified, production efficiency is increased, production cost is lowered, and labor intensity of operation workers is reduced.
