[0002] A screw extruder is a device that relies on the pressure and shear force generated by the rotation of the screw to enable the base material to be fully plasticized and evenly mixed, and finally formed through a die. The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it is widely used in the forming and processing of extruded products;

[0003] During the workshop production process, a motor is mostly used as the power source to cooperate with the reduction gearbox to make the equipment run. At present, most of the connections between the motor and the reduction gearbox are made by couplings, and the coaxiality of the couplings cannot be guaranteed, resulting in low connection stability, affecting the transmission efficiency and resulting in high transmission noise. Therefore, an energy-saving and noise-reducing extruder is proposed. Content of the Utility Model
