The present utility model discloses a twin-screw vented coating extruder, relating to the field of extruders, comprising a mounting plate. A twin-screw extruder is fixedly connected to the upper end of the mounting plate, a vent assembly is fixedly and threadedly connected to the upper end of the twin-screw extruder, a feeding hopper is fixedly connected to the upper end of the twin-screw extruder, a connecting pipe is fixedly connected to the lower end of the feeding hopper, a branch pipe is fixedly connected to the lower end of the connecting pipe, and a flow limiting assembly is fixedly connected to the lower end of the branch pipe. With the above structure, the present utility model carries out feeding under the rotation of a conveying auger, and can control the speed of the conveying auger by controlling the motor speed, so that the feeding speed becomes slow when the speed of the conveying auger decreases and increases when the conveying auger accelerates. Therefore, when using the twin-screw extruder, flow limiting through the conveying auger is more convenient and has a better flow limiting effect.
