본 고안은 코팅 필름의 건조 장치에 관한 것이다.The present invention relates to a drying apparatus for a coating film.
코팅 필름의 제조는 코팅액을 필름의 표면에 도포하고 건조 장치에서 코팅액의 휘발 성분을 제거함으로써 행하여 진다.The production of the coating film is performed by applying the coating liquid to the surface of the film and removing the volatile components of the coating liquid in a drying apparatus.
일반적으로 행하여 지고 있는 코팅필름의 건조 방법은 제3도에서와 같이 코팅면의 상부에서 전기 히터, 또는 열풍을 가하는 방법이다.The drying method of the coating film generally carried out is a method of applying an electric heater or hot air at the top of the coating surface as shown in FIG.
그러나 이와 같은 건조 방법은 코팅면의 두께가 10㎛이상 일 경우 코팅의 외층(표면)과 코팅면의 내부와의 불균형적인 건조에 의하여 건조된 후 필름의 표면에 기포가 형성되어 있거나 또는 쭈글쭈글한 이른바 오랜지 필(orange peel)현상이 발생되는 등 코팅표면상태가 매우 불량하게 되는 문제점이 있다.However, such a drying method is that if the thickness of the coating surface is 10㎛ or more, after drying by unbalanced drying of the outer layer (surface) of the coating and the inside of the coating surface, bubbles are formed or crumpled on the surface of the film. There is a problem that the coating surface state is very poor, such as so-called orange peel phenomenon.
또한 코팅면의 표면의 내부보다 먼저 경화됨으로써 코팅 내층에 코팅 용매가 잔류하게 되어 도포층의 물성이 경시 변화가 일어나게 된다.In addition, since the coating solvent is left in the coating inner layer by curing before the inside of the surface of the coating surface, the physical properties of the coating layer change over time.
또한 건조 초기에 과잉의 용매가 증발됨으로써 건조장치의 구동 롤러에 결로가 발생되어 코팅필름이 건조 장치에 내부에서의 진행속도가 불균일하게 되어 제품에 코팅 웨브(coating web)의 주름이 발생하게 된다.In addition, the excess solvent is evaporated at the beginning of drying, condensation is generated on the driving roller of the drying apparatus, and the coating film is uneven in the traveling speed of the drying apparatus, thereby causing wrinkles of the coating web on the product.
본 고안은 상기와 같은 종래 장치의 문제점을 해결하기 위하여 안출된 것으로써 구동롤러의 결로 형성을 방지하며 코팅면의 표면 및 내부에서의 균일한 건조가 이루어질수 있는 코팅필름의 건조 장치를 제공하려는 데에 그 목적이 있다.The present invention has been made to solve the problems of the conventional apparatus as described above to prevent the formation of condensation of the driving roller and to provide a drying apparatus of the coating film that can be uniformly dried on the surface and inside of the coating surface The purpose is.
상기의 목적을 달성하기 위하여 본 고안은, 구동롤러, 열풍공급장치, 배기장치로 이루어지는 여러개의 건조실이 연결되어 이루어지는 코팅 필름 건조 장치에 있어서, 흡착롤러를 구동롤러로써 사용하고, 열풍공급장치를 구동롤러 하부에 설치하고, 배기 장치를 구동롤러 상부에 설치하는 건조실을 미건조 코팅 필름 도입부에 형성하는 것을 특징으로 하는 코팅 필름 건조장치를 제공한다.In order to achieve the above object, the present invention is a coating film drying apparatus in which a plurality of drying chambers consisting of a driving roller, a hot air supply device, and an exhaust device are connected, using an adsorption roller as a driving roller, and driving a hot air supply device. Provided is a coating film drying apparatus, characterized in that the drying chamber is installed in the lower portion of the roller, the exhaust chamber is installed in the upper portion of the drive roller to form an undried coating film introduction portion.
본 고안에 따른 장치를 도면에 따라 보다 상세히 설명하면 다음과 같다.Referring to the device according to the present invention in more detail as follows.
제1도는 본 고안에 따른 건조실을 포함하는 코팅 필름 건조 장치이다.1 is a coating film drying apparatus including a drying chamber according to the present invention.
본 고안에 따른 건조실은 코팅 필름의 건조 장치의 도입부에 설치되는 제1건조실(11)을 형성한다.Drying chamber according to the present invention forms a first drying chamber 11 is installed in the introduction of the drying apparatus of the coating film.
제1건조실(11)에서 열풍은 구동롤러(4)의 아랫부분에 위치한 열풍 공급구(5)로부터 공급되어 구동롤러(4)와 필름(3)을 가열시킨 후 구동롤러(4)의 윗부분에 위치한 배기장치(16)으로 배기되어 코팅면의 증발 성분을 제거시킨다.In the first drying chamber 11, hot air is supplied from the hot air supply port 5 located at the lower portion of the driving roller 4 to heat the driving roller 4 and the film 3, and then to the upper portion of the driving roller 4. The evacuation unit 16 is evacuated to remove evaporation components of the coating surface.
이에 따라 코팅면에서 발생된 증발 성분이 구동롤러에 결로되는 종래 건조 장치에서 발생되었던 문제점은 본 고안의 장치에서는 열풍 공급 장치(6)가 구동 롤러(4) 하부에 위치하여 건조실(11)내로 열풍을 되면 구동 롤러가 동시에 가열되어 증발 성분이 구동롤러에 결로되지 않게 된다.Accordingly, a problem that has occurred in the conventional drying apparatus in which the evaporation component generated on the coating surface is condensed on the driving roller is that the hot air supply device 6 is located below the driving roller 4 in the apparatus of the present invention and the hot air into the drying chamber 11. In this case, the driving rollers are simultaneously heated to prevent condensation of evaporating components from the driving rollers.
또한, 본 고안에 따른 장치에서는 열풍이 코팅 필름(3)의 배면으로부터 공급되므로 코팅필름의 필름 부분이 먼저 가열되어져 코팅층으로 열이 전달되어 지므로 코팅용매의 휘발이 코팅층의 배면으로부터 이루어지게 되며 이에 따라 코팅 표면이 경화되기 전에 코팅 내면이 경화되어 종래 장치에서 문제가 되었던 코팅면에서의 기포발생 또는 오랜지 필의 발생이 방지되어 진다.In addition, in the apparatus according to the present invention, since the hot air is supplied from the back of the coating film 3, the film portion of the coating film is first heated and heat is transferred to the coating layer, so that the volatilization of the coating solvent is made from the back of the coating layer. Before the coating surface is cured, the coating inner surface is cured to prevent the occurrence of bubbles or orange peel on the coating surface, which has been a problem in conventional devices.
다만 본 고안의 장치에 있어서 열풍이 구동롤러 하부에서 공급되어 까닭에 필름이 구동롤러로 부터 들뜨게 되는 문제점이 발생된다.However, in the apparatus of the present invention, hot air is supplied from the lower portion of the driving roller, and thus, a problem arises in that the film is lifted from the driving roller.
이러한 문제점은 구동롤러를 제2도와 같은 구조를 갖는 흡착롤러로 사용하므로써 해결되어 진다.This problem can be solved by using the driving roller as the adsorption roller having the structure as shown in FIG.
흡착롤러는 원통상의 롤러의 표면을 메시 또는 다공질체로 형성하고 롤러 내부에 진공을 걸어 줌으로써 흡착롤로 표면은 물체를 흡착하려는 흡착력이 발생된다.The adsorption roller forms the surface of the cylindrical roller as a mesh or a porous body, and a vacuum is applied to the inside of the roller to generate an adsorption force for adsorbing an object onto the surface of the adsorption roller.
이에 따라 건조실(1)에서 코팅필름은 흡착롤러에 밀착되게 되어 코팅필름이 떨리거나 고정 롤러로 부터 이탈되어 지는 것이 방지된다.Accordingly, the coating film in the drying chamber 1 is in close contact with the adsorption roller to prevent the coating film from shaking or being separated from the fixing roller.
