The invention discloses a flocking machine with a superfluous velvets absorption storage function. The flocking machine comprises a machine body. A pedestal is arranged at the lower end of the machine body. Two ends of the pedestal are provided with a strut respectively. A flocking box is slidingly connected between the struts. A material storage box is fixedly connected at the upper end at one side of the flocking box. The internal wall at two sides of the material storage box is provided with two agitator motors. A rotating shaft is connected between the agitator motors. An agitator arm is vertically and fixedly connected on the rotating shaft. The lower end of the material storage box is vertically provided with an upper guide duct, one end of which is connected to a suction fan. One end of the suction fan is connected to the upper guide duct. The other end of the suction fan leads downwards to a lower guide duct, one end of which is connected to an input end of the suction fan and the other end of which horizontally leads into the flocking box. Through the above mode, superfluous velvets inside the flocking box can be removed after flocking, thus preventing velvets from flying out and being inhaled into the body of working staff.
