Abstract
플라이트부를 포함하는 전체의 온도를 균등히 제어하여 피압물재의 스크류면의 부착을 방지할 수 있는 압출기용 스크류를 제공한다.
심부의 중심부에 선단측을 폐쇄한 중심구멍과, 이 중심구멍내에 삽입되고, 플라이트부의 기판부에 대응하는 깊이위치로 선단을 개구되어 있다. 그 선단부 외주와 중심구멍 내면과의 사이를 환상 시일부재로 폐쇄된 내관과를 설치하고, 내관내에 왕로, 외주측에 복로를 갖는 2중관상의 주류로를 형성하고 있다. 플라이트부의 배면측에 그 배면에 따라서 형성됨과 동시에 전후 단올반경방향의 연통구멍을 사이에 두고 주류로의 왕로와 복로에 연통시킨 재킷상의 나선유로를 설치하여 이루는 스크류로 한다. 도입된 매체를 주류로 플라이트부 배면의 나선유로를 통하여 순환시켜 플라이트부를 포함하는 전체의 온도를 균등하게 제어할 수 있다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 관한 압출기용 스크류의 일실시예를 도시하는 정단면도이다.
