This utility model relates to a structure for blocking mutual heat transfer between barrels of a twin-screw extruder, which comprises a first barrel, a second barrel is movably installed on the outer surface of the first barrel, a second flange is fixedly installed on the outer surface of the second barrel, a first flange is fixedly installed on the outer surface of the first barrel, and a reinforcing structure is movably installed on the outer surfaces of the first flange and the second flange. When the structure for blocking mutual heat transfer between barrels of the twin-screw extruder is in use, the first flange and the second flange are butted and connected first, then the top and bottom of the first flange and the second flange are reinforced and fixed by a reinforcing plate to realize preliminary fixation, then a fixing bolt passes through the reinforcing plate, the first flange and the second flange for reinforcement, and then is threadedly connected with the outer surface of the right side of the fixing bolt by an octagonal nut; after the connection is completed, a screw rod is driven to rotate by turning a knob.
