The invention discloses a ring-pull can flattening and recycling machine. The ring-pull can flattening and recycling machine comprises a bottom plate, wherein two supporting legs are fixedly connected with the upper surface of the bottom plate; the upper surfaces of the supporting legs are fixedly connected with the lower surface of a supporting plate; two supporting tables are fixedly connected with the upper surface of the supporting plate; the upper surfaces of the supporting tables are fixedly connected with the lower surface of a motor; the output shaft of the motor is fixedly connected with a rotating disc. According to the ring-pull can flattening and recycling machine, the motor drives the rotating disc to rotate, so that a first rotating shaft which is sleeved with a first bearing rotates; besides, under the matched actions of a connecting rod, a second bearing and a second rotating shaft, extruding blocks which are positioned at the two ends in a sliding groove get close to the middle synchronously, a ring-pull can is extruded more regularly; moreover, each ring-pull can which falls off through a first through hole is extruded, a defective product which is not extruded is avoided, the extruded ring-pull can falls into a trolley directly through the first through hole, and the working efficiency is greatly improved.
