摘要： A screw is incorporated in a heating barrel, and the tail end of the screw is rotatably supported by the front surface of an intermediate plate. Behind the intermediate plate, two linear motor units are connected in parallel and arranged around the shaft of the screw to form axial symmetry. The output shafts of the linear motor units are connected to the tail end of a driving shaft through a common connecting arm, and the leading end of the driving shaft is fixed to the rear surface of the intermediate plate. Each of the liner motor units is constituted by a plurality of voice coil linear motors connected in parallel. Each of the linear motor units can be independently controlled. Voice-coil linear motors to be used are selected according to the type of product to be manufactured.
