The present invention belongs to the technical field of powder coating production, and in particular relates to a twin-screw extruder comprising a base. An extrusion mechanism is arranged above the base, a feeding mechanism is arranged above the extrusion mechanism, and a power transmission mechanism is arranged on one side of the extrusion mechanism. Powder coating is crushed by the cooperation of a power roller and an unpowered roller, and then enters the extrusion box through a guide inclined plate. A driving motor, a reducer and a rotating transmission assembly are provided to drive a rotating screw assembly to rotate and extrude. A rough layer is arranged on the outer surface of the conveying and extrusion blade to increase friction between the blade and powder material, enabling effective conveying of powder material during rotation. A cleaning assembly is provided to clean missed powder coating, and an electric heating tube is provided to quickly transfer heat to powder in a C-shaped frame for heating, with high heating efficiency, no obvious temperature difference and improved extrusion efficiency.
