<p>PURPOSE:To improve the efficiency of charging plastic waste to an extruder, etc. and molding said waste by providing right and left belt conveyors along a funnel-shaped hopper of a conveyor chamber and disposing a pair of grooved press- contact rolls in the lower part thereof. CONSTITUTION:Right and left conveyors 6A, 6B consist of prime moving wheels 7, 11, intermediate wheels 9, 13, driven wheels 8, 12 and belts 16, 17. Guide wheels 14, 15 are respectively provided between the wheels 7, 9 and the wheels 9, 13. A pair of grooved press-contact rolls 20, 21 are provided in the lower part of a conveyor chamber 5 and parallel grooves are disposed to the rolls 20, 21 at equal pitches respectively in the axial and peripheral directions. The belts 16, 17 turn downward with each other and waste raw materials are forced downward by the vertical traveling parts 16a, 17a thereof. The materials are heated and penetrated into the grooves by the rolls 20, 21, by which the material is press- contacted and united to one body. The raw materials are treated to a continuous belt shape by such mechanism, by which the efficiency for molding is improved.</p> |
