COUPLING DEVICE AND FEEDING SYSTEM FOR MOLTENED RESIN

Abstract

A molten resin feed system couples a decontamination machine 80, which discharges molten resin to be recycled from an outlet 801, with an injection molding machine 90, which comprises a plasticizing cylinder 91, including an inlet 911 through which the discharged molten resin is entered and which heats the molten resin, and an injection cylinder, which is independent of the plasticizing cylinder 91 and which injects the heated molten resin into a mold, wherein a coupling device 10 couples the decontamination machine 80 with the injection molding machine 90 by connecting one end of a tube, formed by tubes 11 to 14 and swivel joints 21 to 23 and through which the molten resin passes, to the outlet 801 via a connecting element 31 and connecting the other end of the tube to the inlet 911 via a connecting element 32.
