Motor-driven guniting machine

The invention discloses a motor-driven guniting machine. The problems that most rotors of an existing pulp shooting machine are driven by a motor during rotary discharging, some rotors even need an explosion-proof motor, and cost is high are mainly solved. The device is characterized in that a rotatable first rotating piece (3) used for discharging is arranged in the discharging cavity, an air inlet hole (11) communicated with an air source and a discharging port (12) corresponding to the first rotating piece are formed in the shell, a second rotating piece (5) is rotatably arranged in the shell, and blades (51) corresponding to the air inlet hole are arranged on the second rotating piece. And the second rotating piece drives the first rotating piece to rotate through a speed reducing mechanism. According to the guniting machine free of motor driving, the first rotating piece is driven to rotate through the second rotating piece pushed by the air source, cost is reduced, and the guniting machine is simple in
