The present utility model relates to the technical field of twin-screw extruders, and discloses a twin-screw extruder for EVA foaming, comprising a twin-screw extruder main body and a feeding hopper. An extrusion end of the twin-screw extruder main body is movably connected with a flange, one side of the flange is fixedly connected with a thermal insulation cylinder, an outer wall of the thermal insulation cylinder is fixedly connected with a thermal insulation sleeve, an inner wall of the thermal insulation cylinder is fixedly connected with a thermal insulation layer, one side of the flange is fixedly connected with a heat conduction cylinder, an inner wall of the heat conduction cylinder is provided with heat conduction holes, an outer wall of the heat conduction cylinder is provided with a mounting groove, and an inner wall of the mounting groove is fixedly connected with a heating rod. The twin-screw extruder for EVA foaming can be equipped with a thermal insulation cylinder at the extrusion end of the device, so as to achieve a thermal insulation effect after the foamed material is extruded, effectively avoid the phenomenon of material adhesion caused by temperature difference due to excessively long transmission during extrusion, and prevent impact on the extrusion molding effect of the foamed material.
