금속튜브는 외부에 내유성 코팅재를 사용하게 되는데, 대부분의 소재가 PVC, PE로 적용이 되고 있다. 최근 엄격한 내유 조건에서도 만족을 하는 고사양이 요구되고 있어 이에 적합한 코팅재 선정 및 개발이 필요한 상황이다. Metal tube is to use oil-resistant coating on the outside, most of the material is applied to PVC, PE. Recently, a high specification that satisfies even the strict oil-resistant conditions is required, it is necessary to select and develop a coating material suitable for this.

불소 코팅된 제품은 화학적 환경에 거의 영향을 받지 않으며, 높은 내열성과 어떤 강한 산, 알칼리 그리고 용제에도 견딜 수 있다. 그리고, 매우 높은 절연성, 낮은 손실률, 우수한 표면저항률을 갖고, 높은 내열성과 저온도 내구력을 가지며 불소 코팅된 표면에는 물이나 기름이 잘 묻지 않고 대부분의 물질이 달라붙지 않기 때문에 세정이 간편하며 내 마모성 등의 고유의 우수한 특성을 지니고 있기에 불소수지 코팅은 산업 전반에 걸쳐 널리 이용되고 있으나 불소 수지의 코팅 방법은 매우 까다로워 필요로 하는 모든 분야에 적용되지는 못하는 실정이다.Fluorine coated products are hardly affected by the chemical environment and can withstand high heat resistance and any strong acids, alkalis and solvents. In addition, it has very high insulation, low loss rate, excellent surface resistivity, high heat resistance and low temperature durability, and fluorine-coated surface does not adhere well to water or oil, and most materials do not stick to it. Fluorine resin coating is widely used throughout the industry because of its inherent superior properties, but the coating method of fluorine resin is very difficult and cannot be applied to all the necessary fields.

또한, 종래의 불소수지 코팅방법은 불소수지 코팅장치는 코팅전에 프라이머 또는 별도의 접착제를 도포하여 코팅하거나 외측면의 표면을 거칠게 하여 코팅하는 공정이 추가로 필요하였다. In addition, in the conventional fluorine resin coating method, the fluorine resin coating apparatus additionally required to apply a primer or a separate adhesive before coating or to coat the outer surface by roughening the surface.

그래서 본 발명의 목적은 별도의 접착제 코팅 공정이 없어도 가능하여 공정을 신속화하고 환경친화적인 불소수지 코팅방법을 제공하는 데 있다.Therefore, it is an object of the present invention to provide a method for rapid and environmentally friendly fluorine resin coating without the need for a separate adhesive coating process.

Figure 2 is a cross-sectional view showing an extruder of the fluororesin coating apparatus for tubes according to the present invention.

이하에서는 첨부된 도면을 참고로 하여 본 발명의 바람직한 실시예에 대하여 설명하고자 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1에 본 발명에 따른 튜브용 불소수지 코팅장치의 바람직한 실시예에 따른 공정순서도이다.1 is a process flow chart according to a preferred embodiment of the fluororesin coating apparatus for tubes according to the present invention.

첨부된 도면을 참조하면 본 발명은 크게 직선교정기(100), 압출기(200), 냉각기(300), 튜브이송기(400)로 이루어진다.Referring to the accompanying drawings, the present invention consists of a linear straightener 100, an extruder 200, a cooler 300, a tube feeder 400.

먼저, 직선교정기(100)는 권취드럼(110)으로부터 권취된 금속튜브(50)를 직선화 하기 위한 장치로서 금속튜브(50)를 직선으로 펼치는 직선화공정(120)과, 직선으로 펼쳐진 금속튜브(50)를 진원이 되도록 성형하는 진원화공정(130)으로 구성된다.First, the linear straightener 100 is a device for straightening the metal tube 50 wound from the winding drum 110, and a straightening process 120 for unfolding the metal tube 50 in a straight line, and the metal tube 50 unfolded in a straight line. ) Is composed of a rounding process 130 for forming a round shape.

이때 진원화시키는 이유는 금속튜브(50)가 권취드럼(110)에 권취될 때에 상호 눌리기 때문에 진원의 형태를 유지하지 못하고 타원의 형태를 유지하게 되어, 그 타원형 상태에서 불소수지(70)를 코팅하게 되면 완성품이 진원을 유지하지 못한다.At this time, the reason for the rounding is that the metal tube 50 is mutually pressed when wound on the winding drum 110, thereby not maintaining the shape of the round shape and maintaining the shape of the ellipse, and coating the fluorine resin 70 in the elliptical state. If you do, the finished product will not keep its origin.

또한, 불소수지(70)가 금속튜브(50)의 외부 표면에 균일하게 코팅되지 못하고 어느 일측으로 편중되게 코팅되는 것을 방지하기 위함이다.In addition, the fluorine resin 70 is not to be uniformly coated on the outer surface of the metal tube 50 to prevent the coating to be biased to any one side.

즉, 직선화공정(120)은 복수 개의 롤러(131)가 상하측으로 서로 교차되게 설치되어 롤러(131)의 사이로 금속튜브(50)가 지나가면서 일직선으로 펼쳐진다.That is, in the straightening process 120, a plurality of rollers 131 are installed to cross each other in an up and down side, and the metal tube 50 passes between the rollers 131 to be unfolded in a straight line.

또한, 진원화공정(130)은 복수 개의 롤러(131)가 서로 마주보게 설치되되, 롤러(131) 외면에 금속튜브(50)의 외경과 밀접되는 내경을 갖는 홈이 마련되어 금속튜브(50)의 외면을 가압하여 진원으로 성형되게 한다.In addition, the rounding process 130 is provided with a plurality of rollers 131 facing each other, a groove having an inner diameter close to the outer diameter of the metal tube 50 is provided on the outer surface of the roller 131 of the metal tube 50 Press the outer surface to form a round shape.

다음으로, 압출기(200)는 직선교정기(100)의 후단에 설치되어 금속튜브(50)의 외측면을 불소수지(70)로 코팅한다.Next, the extruder 200 is installed at the rear end of the linear straightener 100 to coat the outer surface of the metal tube 50 with the fluorine resin (70).

이를 위해 압출기(200)는 도 1 및 도 2에 도시한 바와 같이 일측을 통해 불소수지(70)가 유입되는 본체(210), 본체(210)에 설치되어 불소수지(70)를 용융시키는 밴드히터(미도시)와, 본체(210)에 설치되어 용융된 불소수지(70)를 가압하는 피스톤(230)과, 노즐(240) 및 단열부재(250)로 이루어진다.To this end, the extruder 200 is installed in the main body 210 and the main body 210 into which the fluorine resin 70 is introduced through one side as shown in FIGS. 1 and 2, and a band heater for melting the fluorine resin 70. (Not shown), a piston 230 installed in the main body 210 to pressurize the molten fluororesin 70, a nozzle 240, and a heat insulating member 250.

이때 밴드히터(미도시)는 본체(210)의 전단과 후단에 각각 설치하여 불소수지(70)가 용융된 상태를 유지시키는 것이 바람직하다.At this time, the band heater (not shown) is preferably installed at the front and rear ends of the main body 210 to maintain the molten fluororesin 70.

한편, 노즐(240)은 본체(210)의 타측에 설치되고 중심에 금속튜브(50) 및 불소수지(70)가 통과하는 통과공(241)이 형성되어 가압된 불소수지(70)를 토출시켜 금속튜브(50) 외주면에 코팅한다.On the other hand, the nozzle 240 is installed on the other side of the main body 210 and the through-hole 241 through which the metal tube 50 and the fluorine resin 70 passes is formed to discharge the pressurized fluorine resin 70 The outer surface of the metal tube 50 is coated.

또한, 단열부재(250)는 노즐(240) 내측에 설치되어 불소수지(70)와 금속튜브(50)간에 공기가 내입된 단열공간(252)을 제공하기 위한 것이다.In addition, the heat insulating member 250 is installed inside the nozzle 240 to provide a heat insulating space 252 in which air is introduced between the fluorine resin 70 and the metal tube 50.

이때 단열공간(252)은 밴드히터(미도시)로 가열되어 용융된 불소수지(70)와, 상온의 금속튜브(50) 사이에 구비되어 상호 온도차이를 유지시킨다. 따라서 불소수지(70)가 금속튜브(50)의 외주면에 코팅될 때 빠르게 식으면서 수축 및 코팅을 하게되어 다른 접착제나 공정이 불필요하다.At this time, the heat insulation space 252 is provided between the fluorine resin 70 and the molten fluorine resin 70 is heated by a band heater (not shown), and maintains the mutual temperature difference. Therefore, when the fluororesin 70 is coated on the outer circumferential surface of the metal tube 50, the fluorine resin 70 is quickly cooled and contracted and coated so that other adhesives or processes are unnecessary.

이를 위해, 단열부재(250)는 원추형상으로 형성되고 중심에 금속튜브(50)가 통과하는 튜브공(253)이 형성되며 선단에 일정깊이로 단열공간(252)이 형성되어 내측과 외측에 각각 금속튜브(50)와 접하는 내측관(253)과 불소수지(70)가 접하는 외측관(254)이 이격되게 구비된다.To this end, the heat insulating member 250 is formed in a conical shape, a tube hole 253 through which the metal tube 50 passes is formed at the center thereof, and a heat insulating space 252 is formed at a predetermined depth at the front end thereof, respectively. The inner tube 253 in contact with the metal tube 50 and the outer tube 254 in contact with the fluorine resin 70 are provided to be spaced apart.

다음으로, 냉각기(300)는 압출기(200)의 후단에 설치되어 금속튜브(50)의 외측면에 코팅된 불소수지(70)를 냉각수로 냉각시키는 것으로, 코팅된 불소수지(70)가 완전히 고착되게 한다. Next, the cooler 300 is installed at the rear end of the extruder 200 to cool the fluorine resin 70 coated on the outer surface of the metal tube 50 with cooling water, and the coated fluorine resin 70 is completely fixed. To be.

한편, 압출기(200)의 전단에 보조냉각기(미도시)를 추가로 설치하여 금속튜브(50)를 냉각한 후 불소수지(70)로 코팅하게 되면, 금속튜브(50)와 불소수지(70) 사이에 벌어진 온도차이만큼 더 빠른게 수축되어 코팅을 효과적으로 할 수 있다.On the other hand, by installing an auxiliary cooler (not shown) in front of the extruder 200 to cool the metal tube 50 and then coated with a fluorine resin 70, the metal tube 50 and the fluorine resin 70 The coating shrinks faster by the difference in temperature between them.

마지막으로, 튜브이송기(400)는 냉각기(300) 후단에 설치되어 상부체인과 하부체인이 무한궤도식으로 회전되면서 상호 교접구간에서 금속튜브(50)를 이송하는 것이다.Finally, the tube feeder 400 is installed at the rear end of the cooler 300, and the upper chain and the lower chain are rotated in an infinitely orbital manner to transfer the metal tube 50 in the interaction section.
