- 공급된 원료를 배럴내에서 스크류를 사용하여 혼합하면서 이동시켜 다이스에서 소정의 폭과 두께로 압출하여 필름을 형헝하는 압출부; 상기 압출부에서 압출된 필름을 소정의 두께가 되도록 가압하면서 견인하여 다음의 공정으로 안내하는 한쌍의 압연롤러와, 상기 압연롤러를 통과한 필름을 냉각시켜 주는 다수개의 냉각롤러와, 상기 냉각롤러를 통과한 필름의 표면이 일정한 조도를 가지도록 고주파를 사용하여 표면처리하는 코로나 유니트로 구성되는 공급부; 그 표면온도가 열매체오일에 의해 유지되고 각각 특정한 속도로 회전되는 다수개의 롤러로 구성되는 연신부; 상기 연신부에서 일정한 두께와 폭으로 만들어진 필름 표면에 엠보싱을 형성하도록 유압으로 작동되는 가압롤러와, 표면에 다수개의 엠보싱돌부가 구비되어 상기 가압롤러와 밀착되어 필름면에 엠보싱을 형성하는 엠보싱롤러로 구성되는 엠보싱부; 필름의 상면과 하면에 선택적으로 인쇄를 수행 할 수 있으며 인쇄후 필름에 묻은 인쇄일크를 완전히 건조시켜 배출하는 인쇄뷔 상기 인쇄부를 통과하여 완성된 필름을 롤에 일정 길이 만큼씩 감아주는 권취부;를 포함하여 구성됨을 특징으로 하는 필름제조용 압출연신장치.
- 제1항에 있어서, 상기 압출부에는 에어실린더에 의해 상기 압연롤러의 표면에 접탈가능하게 설치되어 압연롤러를 냉각시키는 보조냉각터치롤러가 다수계 설치되고, 상기 압연 롤러에 상기 필름이 감겨지는 길이를 보다 길게 하여 냉각효과를 높여주는 권취롤러가 구비됨을 특징으로 하는 필름제조용 압출연신장치.
- 제1항에 있어서, 상기 연신부에는 연신과정이 필요치 않은 필름을 상기 엠보싱부로 직접 전달하기 위한 다수개의 안내롤러가 프레임의 상단에 각각 설치됨을 특징으로 하는 필름 제조용 압출 연신장치.
- 제1항에 있어서, 상기 엠보싱부에는 상기 가압롤러와 엠보싱롤러를 통과하면서 형성된 엠보싱의 형상을 보존하기 위한 냉각롤러가 더 구비됨을 특징으로 하는 필름제조용 압출 연신장치.
- 제1항에 있어서, 상기 엠부싱부의 인쇄부의 상이에는 엠보싱부에서 인쇄부로 전달되는 필름의 장력을 조절하는 벨로실린더유니트가 더 구비됨을 특징으로 하는 필름제조용 압출연신장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
