본 발명은 합성수지관 및 그 제조장치와 제조방법에 관한 것으로 특히 강도가 높은 합성수지관을 제공할 수 있도록 하였다.The present invention relates to a synthetic resin tube, a manufacturing apparatus and a manufacturing method thereof, in particular to provide a high strength synthetic resin tube.
종래의 합성수지관은 제1도와 같이 보강돌부(1)가 형성된 합성수지 테이프(2)을 성형하고, 상기 합성수지 테이프(2)를 권회하여 합성수지 테이프(2)의 연결면(3)을 이미 감겨진 테이프(2)의 내경형성면(4)위에 감겨 접착되도록 하여 합성수지관(5)을 성형하였다.The conventional synthetic resin pipe is formed of a synthetic resin tape 2 having a reinforcement protrusion 1 formed thereon as shown in FIG. 1, and wound around the synthetic tape 2 to wind the connection surface 3 of the synthetic resin tape 2 already wound. The synthetic resin tube 5 was molded by being wound on the inner diameter forming surface 4 of (2) to be bonded.
따라서, 합성수지관(5)이 됨과 더불어 합성수지관(5)의 외주연에 보강돌부(1)가 나선형으로 형성되었다.Therefore, the reinforcement protrusions 1 were spirally formed on the outer periphery of the synthetic resin pipe 5 as well as the synthetic resin pipe 5.
그러나, 합성수지관(5)의 외주연에 보강돌부(1)가 나선형을 이루는 반면 ＂L＂넓이의 홈(6)이 나선형으로 형성되어져 있기 때문에 홈(6)부분에 대하여서는 강도가 약하였다.However, since the reinforcement protrusion 1 spirals on the outer periphery of the synthetic resin pipe 5, the groove 6 having a ＂L＂ width is formed in a spiral shape, so the strength of the groove 6 is weak.
따라서, 합성수지관(5)을 보관하거나 운반 및 시공시에 꺾이게 되면 홈(6) 부분이 꺾임과 동시에 터지거나 구멍이 생기게 되는 문제점들이 있었다.Therefore, when the synthetic resin tube 5 is stored or folded at the time of transportation and construction, there are problems in that the groove 6 is folded and burst or formed at the same time.
본 발명은 이러한 점을 감안하여 발명한 것으로서, 테이프에 형성된 보강돌부의 선단 일측면에 보강연결면을 구비하여 감겨지는 테이프의 내경형성면에 연결면이 접착됨과 동시에 보강연결면의 선단이 감겨진 보강돌부와 외주면에 감기면서 접착되어 합성수지관이 성형되도록 함으로써 성형된 합성수지관의 외주연에 종래와 같이 홈부가 형성되지 아니하고 외경면이 형성됨으로써 강도 높은 합성수지관을 제공하는데 목적이 있다.The present invention has been invented in view of this point, and the connection surface is bonded to the inner diameter forming surface of the tape wound with a reinforcing connection surface on one side of the front end of the reinforcement protrusion formed on the tape, and the front end of the reinforcing connection surface is wound It is an object to provide a high strength synthetic resin tube by forming the outer diameter surface of the outer peripheral surface of the molded synthetic resin tube is formed by bonding the reinforcement protrusion and the outer circumferential surface while being bonded to the outer peripheral surface of the formed synthetic resin tube.

이와 같은 본 발명의 작용효과를 제2도 내지 제6도에 의하여 설명하면 다음과 같다.Referring to the operation and effect of the present invention as shown in Figures 2 to 6 as follows.
합성수지관을 제조코저 할때는 하이덴시티 폴리에틸렌(HDPE)를 210-230℃로 용융하여 성형기(201)에 의하여 테이프(101)를 통상의 방법으로 압출한다.When manufacturing a synthetic resin tube, high density polyethylene (HDPE) is melted at 210-230 ° C., and the tape 101 is extruded by a conventional method by the molding machine 201.
이때 테이프(101)는 보강돌부(102)와 내경형성면(103) 및 연결면(104)과 상기 보강돌부(102)의 일측면에 보강연결면(110)이 형성되도록 성형한다.At this time, the tape 101 is molded so that the reinforcing connecting portion 110 and the inner diameter forming surface 103 and the connecting surface 104 and the reinforcing connecting surface 110 is formed on one side of the reinforcing protrusion 102.
이와 같이 성형되는 보강돌부(102)내의 중공부(102')에 제5도와 같이 냉각관 (202)을 삽입하고, 상기 냉각관(202)으로 냉각수를 유입시켜 성형되는 테이프(101)의 보강돌부(102)부분을 180℃정도까지 냉각시켜준다.The reinforcing protrusion of the tape 101 formed by inserting the cooling tube 202 into the hollow portion 102 ′ of the reinforcing protrusion 102 formed as described above with reference to FIG. 5 and introducing coolant into the cooling tube 202. Cool the (102) part to about 180 ℃.
이와 같이 냉각시켜주는 이유는 성형기(201)에서 압출되어 성형되는 테이프(101)은 온도가 높아 흐느적 거리는 테이프(101)를 권회시 테이프(101)가 원형을 유지토록 하기 위하여 냉각시켜준다.The reason for this cooling is that the tape 101 extruded and molded in the molding machine 201 cools the tape 101 so that the tape 101 maintains its original shape when the tape 101 is wound up due to a high temperature.
즉, 냉각관(202)으로 유입된 냉각수는 테이프(101)의 온도를 냉각시킨 후 냉각관 (201)내에 설치된 배출관(203)의 선단을 통하여 유입되어 배출된다.That is, the cooling water introduced into the cooling pipe 202 is cooled through the front end of the discharge pipe 203 installed in the cooling pipe 201 after cooling the temperature of the tape 101 is discharged.
이와 같이 냉각된 테이프는 공지의 권회과정에 의하여 권회되면서 보강돌부(102)에 형성된 보강연결면(110)이 이미 감겨진 보강돌부(102)의 외주면에 접착되는데 이때 상기 보강연결면(110)을 압착롤러(204)가 눌러주기 때문에 접착이 잘 이루어진다.The tape thus cooled is wound by a known winding process, and the reinforcing connection surface 110 formed on the reinforcing protrusion 102 is bonded to the outer circumferential surface of the reinforcing protrusion 102 already wound. Since the pressing roller 204 is pressed, the adhesion is well made.
이때, 보강연결면(102)과 연결면(104)사이에 삽입되어져 있는 압착코어(205)가 압착롤러(204)의 누르는 힘에 의하여 연결면(104)을 눌러주기 때문에 연결면(104)이 내경형성면(103)에 밀착되는 것이다.At this time, since the pressing core 205 inserted between the reinforcing connecting surface 102 and the connecting surface 104 presses the connecting surface 104 by the pressing force of the pressing roller 204, the connecting surface 104 is It is in close contact with the inner diameter forming surface 103.
그리고, 압착코어(205)내에 형성된 냉각수 유입관(206)으로 유입된 냉각수가테이프(101)을 열을 냉각시켜 주고 난 후 배출관(207)을 통하여 배출된다.Then, the cooling water introduced into the cooling water inlet pipe 206 formed in the crimping core 205 cools the heat of the tape 101 and is discharged through the discharge pipe 207.
이와 같이 형성된 합성수지관은 테이프(101)에 형성된 연결면(104)이 이미 감겨진 내경형성면(103)에 감겨서 접착되어 내경이 형성하고, 테이프(101)의 보강돌부(102)의 일측면에 형성된 보강연결면(110)이 이미 감겨진 보강돌부(102)의 외주면에 감겨져 접착되어 외경을 형성하였다.The synthetic resin tube formed as described above is bonded to the inner diameter forming surface 103 on which the connecting surface 104 formed on the tape 101 is wound and bonded to form an inner diameter, and one side surface of the reinforcing protrusion 102 of the tape 101 is formed. Reinforcing connection surface 110 formed in the wound around the outer peripheral surface of the reinforcing protrusions 102 is already wound to form an outer diameter.
따라서, 본 발명의 합성수지관은 종래와 같이 외주면에 홈부가 없이 외주면에 형성하여 줌으로써 강도가 높은 합성수지관을 제공함으로써 운반 및 설치시에 합성수지관이 꺾여 터지는 등의 문제점을 제거할 수 있는 발명이다.Therefore, the synthetic resin tube of the present invention is an invention that can eliminate problems such as breaking the synthetic resin tube during transportation and installation by providing a high strength synthetic resin tube by forming on the outer peripheral surface without the groove portion on the outer peripheral surface as in the prior art.
