Abstract

본 발명은 각종의 주택이나 아파트등 건축물의 난방용으로 시공되는 포리에틸렌 파이프의 표면 코팅장치에 관한 것으로, 본 발명의 특징은 포리에틸렌 파이프의 제조시 제조와 동시에 상기 파이프의 내외면에 동일 재질로 된 원료를 일체적으로 코팅하므로서 유연성이 양호하여 사용수명의 연장은 물론 내구성을 강화하고, 특히 표면이 매끈하여 온수의 순환을 원활하게 한 것이다.The present invention relates to a surface coating apparatus of polyethylene pipes which are constructed for heating of buildings such as various houses or apartments, and features of the present invention are made of the same material on the inner and outer surfaces of the pipes at the same time as the production of polyethylene pipes. By coating the raw material integrally, the flexibility is good, so as to prolong the service life, as well as to enhance the durability, and the surface is smooth to facilitate the circulation of hot water.

본 발명은 투입금형(2)의 측방에는 외부금형(5)과 내부금형(5)을 설치하여 파이프를 생산할 수 있게 한 통상의 코팅장치(1)에 있어서, 투입금형(2)의 중앙에는 공간부(8)를 형성하되, 공간부(8)의 사이에는 수개의 연결편(9)을 형성하여 일측에는 급기공(10)과 코팅재투입구(11)를 각각 형성하여 내부금형(5)과 가이드관(6)을 관통하여 공급되게 하고, 가이드관(6)을 연결하는 접속구(12)를 나사 결합하며, 내부금형(5)의 내측 선단에는 유도돌부(13)를 상하에 각각 형성하며, 외부금형(3)의 일측에는 횡방향으로 투입금형(2)의 코팅재투입로(11)와 동일라인으로 코팅재투입로(15)를 형성하고, 외부금형(3)의 가장자리 선단측에 설치되는 코팅금형(4)의 내부에는 코팅재유도로(16)를 형성하여 포리에틸렌 파이프의 내외면에 일체적으로 코팅할 수 있게 한 것이다.In the present invention, in the conventional coating apparatus (1) in which the outer mold (5) and the inner mold (5) is installed on the side of the injection mold (2) to produce a pipe, the space in the center of the injection mold (2) Forming part (8), but several connecting pieces (9) are formed between the space part (8) and on one side the air supply hole (10) and the coating material inlet (11), respectively, the inner mold (5) and the guide tube (6) to be supplied through, screwed to the connector (12) connecting the guide tube (6), the inner end of the inner mold (5) is formed with guide protrusions (13) up and down, respectively, the outer mold On one side of (3) is formed in the transverse direction with the coating material input path (15) in the same line as the coating material input path 11 of the injection mold (2), the coating mold installed on the edge end side of the outer mold (3) 4) inside the coating material induction path 16 is to be integrally coated on the inner and outer surfaces of the polyethylene pipe.
