Abstract
Improvements introduced in plastic screw preplasticizers, characterized by the fact that the pre-plasticizing cylinder, the screw and the speed reducer housing for the transmission of the rotation movement to the screw are joined together so that they can undergo rigid displacements simultaneously caused by a motor cylinder, while outside the cylinder and coaxially therewith is provided a chamber for accumulation of the plastic material, constituted by a fixed cylinder joined, by means of an injector or a row head, to a molding machine by injection or by blowing, entering said chamber a rod provided with an end piston and extending from the end of the preplastic cylinder, said rod being provided with an axial conduit that puts the inside of the plasticizing cylinder in communication with said cylinder. accumulation chamber, so that matter p The feedstock fed by the screw can progressively pass inside said accumulation chamber, to be compressed by the end piston of said rod and forced out by the injector or the row when, by the action of the motor cylinder, they move axially. the preplasticizing cylinder, the screw and the speed reducer.
