The mechanism for feeding the flat pieces comprises a push plate and a conveying belt, wherein the push plate is arranged above the conveying belt; the moving direction of the push plate is identical to the conveying direction of the conveying belt; a backup plate corresponding to the push plate is arranged at the tail end of the conveying belt; a lateral friction belt is arranged on the backup plate; and the moving direction of the lateral friction belt is vertical to the moving direction of the push plate. The mechanism for feeding the flat pieces is characterized in that the tail end of the conveying belt is connected with a group of horizontally arranged conical roller wheels in the width direction of the conveying belt; the axis of each conical roller wheel is vertical to the push plate; the big end of each conical roller wheel is close to the backup plate and the small end of each conical roller wheel is close to the push plate; the conical roller wheels rotates towards the moving direction of the lateral friction belt; air suction holes are formed in the lateral friction belt; and an air suction pump sucks air from the air suction holes. Flat piece piles are formed into a front and back staggered tile overlapped shape by the feeding mechanism, so the efficiency and the success rate of the subsequent 'single seal separation' are enhanced.
