The invention relates to the field of waste plastic recycling, and aims to provide a plasticizing machine for recycled crushed films. The plasticizing machine for recycled crushed films comprises a frame, a shredding, stirring and pre-plasticizing device equipped with a feed hopper and a discharge port, a plasticizing and toughening device, and a vacuum exhaust and filtering device. The plasticizing and toughening device comprises a barrel provided with a barrel heating device and connected to the frame, a central spiral push rod pivotally connected to the barrel, a plurality of outer spiral push rods distributed circumferentially along the central spiral push rod and pivotally connected to the barrel, and a spiral push rod driving device. The barrel is provided with a plasticizing inlet located at the rear of the side wall of the barrel and communicated with the discharge port, a plasticizing outlet located at the front end of the barrel, and an air extraction hole communicated with the inlet of the vacuum exhaust and filtering device. During the plasticizing process, the plasticizing machine achieves good effects in mixing, extruding and kneading plasticizing raw materials, facilitates gas discharge, and produces recycled plastic raw materials with high toughness.
