This utility model discloses an extrusion blow molding machine, comprising a machine body and a motor. The motor is placed on top of the machine body, and an extrusion adjustment device is installed inside the machine body. The extrusion adjustment device includes a transmission body, a sealing plate, a conveying screw, a heater, a check ring, an extrusion port, a rotating ring, a rotating rod, a gear one, a gear two, a reciprocating screw, a fixed block, a movable plate, and a cutting plate. During operation, the conveying screw connected to the bottom rotates within the sealing plate, transporting the material to the extrusion port. When adjusting the size of the extrusion port, the rotating ring is rotated, causing gear one to mesh with the two gears two on either side. This rotates the reciprocating screw, causing the two sets of movable plates on the reciprocating screw to move relatively or oppositely. The extrusion port has grooves, and the movable plates are in contact with the bottom of the extrusion port. The cutting plates on the movable plates change the size of the extrusion port, thus achieving the effect of adjusting the extrusion, allowing the device to produce a wider range of plastics and improving its practicality.
