PROBLEM TO BE SOLVED: To provide a screening device for soft and hard plastics capable of efficiently separating and screening by using the suction force of air and the tare of waste.SOLUTION: A screening device 1 for soft and hard plastics has: a conveyor unit 4 in which a mesh conveyor belt 9 is inclinedly arranged, and the waste materials mixedly including lightweight soft plastics and hard plastics weighing to some extent are charged on a conveying face; and an air suction means 21 which is arranged making the opening 22a being a suction port approach to the conveying rear face of the mesh conveyor belt 9 and brings to act a suction force on the conveying rear face side from the conveying face side. The device is configured so as to convey the soft plastics while adsorbing on the conveying face of the mesh conveyor belt 9 by the suction force of the air suction means 21 to discharge from a conveyance top end, and to drop the hard plastics unable to adsorb by the suction force by the tare thereof below the conveyor belt 9 to discharge and thereby, to separate and screen the soft and hard plastics. |
