The invention relates to an intelligent biomass molding machine with electric mold switching, including a humidity sensor, a temperature controller, a heating wire, a feeding hopper, a feeding belt, a stirring device, a granulator, a die changing plate, and a die changing plate motor, The humidity sensor can measure the moisture content of the biomass powder in real time, and control the temperature controller to change the heating current of the heating wire of the conveyor belt to adjust the temperature to control the moisture content of the biomass powder. The stirring device continuously stirs the biomass powder to prevent agglomeration and ensure the normal operation of the molding machine. There are multiple molds with different hole diameters and through-hole depths installed on the die changing plate, and the rotation of the die changing plate is controlled by the die changing plate motor to realize the installation of different flat dies according to requirements. The present invention is a biomass molding machine with automatic mold switching. By realizing flat mold switching, moisture content control, and biomass powder stirring, the normal operation of the molding machine is ensured, and biomass molding particles are produced according to requirements, which improves the adaptability of the molding machine. and versatility.
