Abstract

본 발명은 압출기의 압출라인에 설치되는 열수축튜브용 압출기의 헤드에 관한 것으로, 특히 성형중 원료의 원활한 공급이 이루어지며, 신속한 배출이 이루어지도록 함과 동시에 열수축튜브의 동심원이 유지되도록 한 열수축튜브용 압출기의 헤드에 관한 것이다.The present invention relates to a head of a heat shrink tube extruder installed in the extrusion line of the extruder, in particular for a smooth shrinkage of the raw material during the molding, to ensure rapid discharge and at the same time to maintain a concentric circle of the heat shrink tube Relates to the head of an extruder.

본 발명의 구체적인 수단은 압출기의 실린더헤드와 수평으로 연결되는 헤드몸체는 써머커플을 장착하여 일단의 주연부에 밴드히터를 설치하고 내부는 소직경의 좌우로 연동되어 축소확대되는 축소경 및 확대경을 일축선 방향으로 형성하고 일측면으로 링히터가 장착되고 타측면은 에어공급부를 갖는 맨드릴홀더가 헤드몸체의 내부와 동축으로 결합되고, 이 맨드릴홀더의 일측면에 원추형 맨드릴이 장착되어 상기 확대경에 동축으로 위치되고 타측면은 니플을 지지하는 니플홀더와 주연에 밴드히터를 갖고 써머커플을 장착한 다이블록을 결합하고, 상기 다이블록은 다이를 지지하는 다이커버를 선단에 갖고 외주연에 설치된 다수개의 센터볼트에 의해서 상기 다이의 중심을 조정하도록 된 것을 특징으로 한다.Specific means of the present invention is that the head body connected horizontally with the cylinder head of the extruder is equipped with a thermocouple to install a band heater at the periphery of one end and the inner side is interlocked to the left and right of the small diameter to reduce the enlargement and enlargement work It is formed in the axial direction and the ring heater is mounted on one side, and the other side is a mandrel holder having an air supply part is coaxially coupled with the inside of the head body, and a conical mandrel is mounted on one side of the mandrel holder and coaxially to the magnifying glass. The other side combines a nipple holder for supporting the nipple and a die block having a band heater at the periphery and a thermocouple mounted thereon, the die block having a die cover for supporting the die at its tip and having a plurality of centers installed at the outer periphery. And to adjust the center of the die by bolts.
