The Teflon forms a very stable compound due to the strong chemical bonding of fluorine and carbon, and thus has almost perfect chemical inertness and heat resistance, non-tackiness, excellent insulation stability, and low coefficient of friction. As such, the fluorine-based synthetic resin has water repellency and oil repellency due to low surface tension, and thus does not leave coating chemical residues such as ink when used as a synthetic resin layer in the coating bar for the applicator of the present invention. Will be effective.

그리고 도 6은 본 발명의 또 다른 실시예로서, 회전용 또는 고정용 로드봉이 실린더 형상이 아닌 복수개의 원호형의 돌출부가 방사상으로 대칭을 이루며 형성된 구성을 도시한다. 상기와 같은 구성은 단일의 실린더 형상에 비하여 복수개의 원호형 돌출부를 이용하여 도포작업을 진행할 수 있으므로 작업성능을 배가할 수 있는 장점을 갖는다.And Figure 6 is a further embodiment of the present invention, a rod or rod for rotation is shown a configuration formed in the radially symmetrical plural arcuate protrusions that are not cylindrical. The configuration as described above has the advantage that the work performance can be doubled since the coating operation can be performed using a plurality of arc-shaped protrusions as compared to a single cylinder shape.

한편, 본 발명에 따른 도포기용 코팅바는 잉크와 같은 코팅액, 즉 도포약품 또는 코팅대상의 종류에 따라 로드봉의 크기, 합성수지층의 나사산형상 및 나사산의 피치, 높이 등이 자유롭게 조절될 수 있다.On the other hand, the coating bar for the applicator according to the present invention can be freely adjusted according to the coating liquid, such as ink, that is, the size of the rod, the thread shape of the synthetic resin layer and the pitch, the height of the thread, etc. according to the type of coating agent or coating object.

이상에서 설명한 바와 같이, 본 발명의 도포기용 코팅바는 실린더 형상의 회전용 또는 고정용 로드봉의 외주면에 피복되며 나사산이 형성된 합성수지층을 피복하여 구성함으로써 세척 및 관리가 용이한 작용효과를 갖는다. As described above, the coating bar for the applicator of the present invention is coated on the outer circumferential surface of the rod or rod for fixing in a cylindrical shape and is formed by coating a synthetic resin layer having a thread, so that the washing and managing is easy.

또한, 본 발명의 도포기용 코팅바는 합성수지층의 재질로서 테프론(Teflon)과 같이 발수성(拔水性) 및 발유성(拔油性)이 뛰어난 불소계열의 수지를 사용하므로 잉크 등의 찌꺼기의 생성을 방지하여 균일한 도포성능을 발휘한다.In addition, the coating bar for the applicator of the present invention uses a fluorine-based resin excellent in water repellency and oil repellency, such as Teflon, as a material of the synthetic resin layer, thereby preventing generation of residues such as ink.
