Being the feeder of the resin raw materials which are installed in the raw materials input port of the heating

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for feeding a resin material for a synthetic resin molding machine with which gas generated in the casing of the screw feeder is exhausted quickly without causing stagnation and quality problems such as a silver streak and a void in the molded product are prevented from occurring.;SOLUTION: The feeding apparatus is arranged at the raw material feed port 80 of the screw feeder 81 equipped with a heater 83 of the synthetic resin molding machine 8. The raw material feed port 80 is connected with an inner cylinder 6 for feeding a raw material and an outer cylinder 7 for exhaustion in a row. The outer cylinder 7 surrounds the inner cylinder 6 and is connected with pulsating suckers 9 and 91. The tapered tip 61 of the inner cylinder 6 is located eccentrically to the raw material feed port 80 on the downstream side of a raw material transported by the screw feeder 81.;COPYRIGHT: (C)2004,JPO&NCIPI
