Description

합성수지 나선관 제조용 다중 프로파일과 그 제조방법 및 이를 이용한 합성수지 나선관{The multi profile and manufacturing method, spiral composition resin pipe for manufacturing spiral composition resin pipe}Multi-profile and manufacturing method for manufacturing synthetic resin spiral tube and its manufacturing method

본 발명은 나선형 합성수지관을 제조할 때 사용하는 프로파일에 관한 것으로, 그 중에서도 특히 프로파일을 2중 또는 3중 등의 다중으로 구성하여서된 다중 프로파일에 관한 것으로, 다중 프로파일을 이루고 있는 내측의 격벽을 수평으로 절단하거나 프로파일의 외측에 홈을 형성하여 제작한 다음 그 외부에 수지를 도포하여 냉각시킴으로써 냉각속도를 균일하게 하여 프로파일이 휘는 것을 방지할 수 있도록 한 것으로서, 다중 프로파일이 제작된 다음 냉각시 외형이 수평을 이룰 수 있도록 하는데 그 목적이 있는 것이다.The present invention relates to a profile used when manufacturing a spiral synthetic resin tube, and more particularly, to a multi-profile consisting of a multi-profile, such as double or triple, the horizontal partition of the inner wall forming a multi-profile It is made by cutting or forming grooves on the outside of the profile, and then applying resin to the outside and cooling it to make the cooling rate uniform so that the profile can be prevented from bending. Its purpose is to make it level.

일반적으로 나선형 합성수지관제조용 프로파일은 ' ㅁ '모양으로 제작한 다음 압출기의 드럼에 나선형으로 감은 다음 프로파일과 프로파일사이에 수지를 주입하여 연결한 다음 냉각하는 방법으로 제작되어 왔다.In general, the spiral synthetic resin pipe manufacturing profile has been produced by the 'ㅁ' shape, then spirally wound on the drum of the extruder, and then injected by connecting the resin between the profile and the profile and then cooled.

그러나 종래에 사용되어온 프로파일은 그 폭이 좁기 때문에 나선형 합성수지관을 제작하는 데에 있어서, 정사각형으로 된 프로파일을 계속 나선형으로 감아 연결하는 방식이기 때문에 제작시간이 오래 걸리는 단점이 있으며, 또한 고가의 수지를 프로파일을 연결할 때 사용함으로서 제작단가가 고가인 단점이 있고, 이로 인하여 나선관의 생산능률을 저하시키게 됨으로서 국제경쟁에 떨어지게 되는 큰 문제점이 있었다.However, the profile used in the prior art has a narrow width, and thus, in the manufacture of a spiral synthetic resin tube, it is a method of winding a square profile continuously in a spiral manner and thus requires a long manufacturing time. There is a disadvantage that the manufacturing cost is expensive by using a profile when connecting the profile, thereby lowering the production efficiency of the spiral tube has a big problem that falls in the international competition.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 나선형수지관 제작용 프로파일을 제작할 때 프로파일의 중앙부가 2중으로 하여 직사각형으로 되게 구성하는 한편 중앙부에 형성되는 격벽의 중간부를 절단되게 구성하거나, 프로파일의 외측 중앙부에 요홈을 형성한 다음 프로파일의 외부에 다시 수지를 코팅하여 냉각시킴으로써, 다중 프로파일을 냉각할 때 외형이 수축되어 절곡되는 것을 방지할 수 있도록 한 것으로서, 이하 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been invented to solve the above problems, when manufacturing the spiral resin tube manufacturing profile, the central portion of the profile is configured to be a double to form a rectangle while the middle portion of the partition wall formed in the central portion, or By forming a recess in the outer center of the profile and then coating the resin outside the profile and cooling it, it is possible to prevent the appearance from shrinking and bending when cooling the multiple profile. When described in detail as follows.

한편 프로파일의 내부에 격벽을 여러개를 설치하여 다중의 통공이 형성되도록 하여도 바람직하다.On the other hand, it is also preferable to provide a plurality of partitions in the interior of the profile to form a plurality of through-holes.

상기와 같이 된 본 발명의 제조방법을 설명하면 다음과 같다.Referring to the manufacturing method of the present invention as described above is as follows.

프로파일 몸체 제조용 압출기에 프로파일 몸체 제조용 수지(폴리에틸렌(PE)과 왕겨 및 목분을 혼합하여서 된 혼합물)을 투입하고, 코팅용 압출기에는 100% 폴리에틸렌수지를 투입하여 용융되게한다.The resin for producing the profile body (a mixture obtained by mixing polyethylene (PE) with chaff and wood flour) is introduced into the profile body making extruder, and 100% polyethylene resin is added to the extruder for coating to melt.

상기와 같은 상태에서 압출기의 끝단부에 ''모양으로 압출공이 형성된 다이를 체결하여 고정한 다음 1번수지를 압출시키면 왕겨 및 목분과 폴리에틸렌수지가 혼합된 혼합물이 압출하게 된다.At the end of the extruder in the same state as above 'The shape of the extrusion hole is formed by fastening the die, and then the first resin is extruded, and the mixture of rice hull and wood flour and polyethylene resin is extruded.

이때 압출물은 다이에 형성된 압출공에 의하여 2중의 프로파일에 형성되는 중앙부 격벽의 중간부가 절단된 상태에서 압출하게 된다.At this time, the extrudate is extruded in the state in which the middle portion of the central partition wall formed in the double profile is cut by the extrusion hole formed in the die.

상기와 같이 프로파일의 몸체를 이루는 혼합물이 압출됨과 동시에 2번 압출기에서 폴리에틸렌수지가 압출되어 몸체압출물의 외부를 코팅하게 되고 ,이 상태에서 2중의 프로파일이 압출하게된다.As described above, the mixture constituting the body of the profile is extruded, and at the same time, the polyethylene resin is extruded in the second extruder to coat the outside of the body extrudates. In this state, the double profile is extruded.

상기와 같이 압출된 2중 프로파일은 곧바로 진공쿨링장치로 유입되어 2중 프로파일이 일정한 형상을 유지할 수 있게 하며 쿨링장치를 통과한 2중 프로파일은 물을 분사하여 냉각시키는 냉각장치를 통과한 다음 나선관 선형용 드럼에 나선형으로 감기게 된다.The double profile extruded as described above immediately flows into the vacuum cooling device to maintain the constant shape of the double profile, and the double profile passed through the cooling device passes through a cooling device that cools by spraying water and then spiral tubes. It is wound spirally on a linear drum.

나선과 제조용 드럼에 2중 프로파일이 감기게 되면 2중 프로파일과 2중 프로파일이 만나는 곳에 나선관 제조용 압출기에 설치된 압출기에서 폴리에틸렌 수지를공급하게 되고, 이 수지를 로울러가 압착한 상태에서 냉각시켜 나선관을 제조하게 되는 것이다.When the double profile is wound around the spiral and the manufacturing drum, polyethylene resin is supplied from the extruder installed in the spiral pipe extruder where the double profile and the double profile meet, and the resin is cooled while the roller is compressed and the spiral tube is cooled. Will be manufactured.

한편 본 발명의 다른 실시예로 2중및 다중 프로파일을 제작할 때 프로파일의 중앙부에 형성된 격벽부의 외측 중앙부에 형성되어 있는 요홈부(6)에 폴리에틸렌수지를 도포하여 수평이 되게 한 상태에서 냉각을 시키게되면 프로파일의 외측에 형성된 폴리에틸렌수지의 냉각속도가 빠르기 때문에 프로파일의 외측 중앙부에 형성된 요홈부(6)에 폴리에틸렌수지가 삽입되어 있기 때문에 금방 냉각하게 되고, 이로 인하여 프로파일의 내, 외측의 냉각속도를 동일하게 유지함으로서, 프로파일이 휘는 것을 방지함으로서, 다중프로파일을 제작할 수가 있는 것이다.On the other hand, when manufacturing the double and multi-profile in another embodiment of the present invention by applying a polyethylene resin to the groove portion 6 formed in the outer central portion of the partition wall formed in the central portion of the profile to cool in a state in which the horizontal Since the cooling speed of the polyethylene resin formed on the outside of the profile is fast, the polyethylene resin is quickly inserted into the groove 6 formed in the outer center of the profile, thereby cooling it immediately. By holding it, you can create a multi-profile by preventing the profile from bending.

이상과 같이 본 발명은 2중 및 다중 프로파일을 제작할 때 중앙부에 형성되는 격벽의 중간부를 절단되게 압출 성형하거나 프로파일의 외측 중앙부에 요홈을 형성한 다음 그 외부에 다시 폴리에틸렌수지를 도포하여서 된 것으로서, 구조 및 방법이 간단하여 제작이 용이하고, 2중 프로파일의 중간부에 형성된 격벽이 절단되어 있기 때문에 2중 프로파일을 냉각할 때 절단부에 의하여 외형이 수축이나 절곡되는 것을 방지할 수가 있으며, 또한 프로파일의 중앙부에 형성된 격벽을 연결하되 그 외측 중앙부에 요홈을 형성하여 폴리에틸렌수지를 도포하여 냉각시킴으로서 다중 프로파일을 제작할 수가 있고, 이로 인하여 합성수지 넓은 면적의 합성수지 프로파일을 이용함으로서 나선관을 단시간에 대량으로 제작함으로 생산량을 최대로 증대시킬 수가 있고, 프로파일을 2중및 다중으로 제작함으로서 연결용 수지를 절감하여 제조원가를 절감할 수가 있는 유용한 발명인 것이다.As described above, the present invention is made by extrusion molding to cut the middle part of the partition wall formed at the center part when forming the double and multiple profiles, or by forming a groove at the outer center part of the profile, and then applying the polyethylene resin to the outside again. And since the method is simple and easy to manufacture, since the partition formed in the intermediate part of the double profile is cut | disconnected, when a double profile is cooled, an external shape cannot be contracted or bent by a cut | disconnected part, and also the center part of a profile It is possible to manufacture multiple profiles by connecting bulkheads formed on the outer wall to form grooves on the outer center and cooling by applying polyethylene resin, thereby producing a large amount of spiral tubes in a short time by using synthetic resin profiles with a large area of synthetic resin.
