Description
본 발명은 고추가루를 만들거나 쌀이나 밀을 가루로 만들 때 사용하는 분쇄기용 분쇄로울러를 개량한 것이다.The present invention is an improvement of the grinding roller for a grinder used when making red pepper powder or rice or wheat flour.
종래의 분쇄기용 분쇄로울러는 주철재로 제조되어 있기 때문에 사용 후에 공기중에 노출되면 표면이 산화하여 녹이 발생하므로 사용하기 전에 이를 깨끗이 제거해야 하는 불편이 있고 사용중에는 로울러 서로가 마찰할 때 마모가 되어 쇳가루가 발생하게 되므로 가공품에 혼입이 되어 인체에 해를 주는 문제점이 있었다.Conventional grinding rollers for grinding machines are made of cast iron, so when exposed to air after use, the surface is oxidized to produce rust. Therefore, it is inconvenient to remove them cleanly before use. There is a problem causing harm to the human body to be mixed into the workpiece.
그러므로, 이를 방지하기 위해 세라믹 단일봉체로 된 분쇄로울러가 개발되어 있으나 이것은 교환하기가 불편하고 파열되면 완전히 새것으로 교체해야 하므로 경비부담이 너무 가중되는 결점이 있었다.Therefore, in order to prevent this, a grinding roller made of a single ceramic body has been developed, but this is inconvenient to replace, and if it is broken, it has to be completely replaced with a new one.
본 발명은 위와 같은 종래의 결점을 시정하기 위하여 개발한 것으로 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention was developed in order to correct the above-mentioned drawbacks as described in detail with reference to the accompanying drawings as follows.
도1은 본 발명의 용사장치 예시도Figure 1 is an illustration of the spraying apparatus of the present invention
도2는 본 발명의 로울러 단면도이다.2 is a cross-sectional view of the roller of the present invention.

도1은 본 발명의 용사장치가 예시되어 있다.1 illustrates an example of the thermal spraying apparatus of the present invention.
즉, 본 발명은 금속제로 로울러 심봉을 만들어 회전장치에 장치하여 회전시키고 코팅할 부분을 노출시킨 다음 용사건을 사용하여 로울러 심봉의 표면에 먼저 니켈파우다를 용사하여 코팅하고, 2차적으로 고순도 산화크롬분말을 용사하여 코팅하므로서 이중의 코팅층을 형성시키고 표면을 연마하여 완성품을 얻게 되는 것이다.That is, in the present invention, the roller mandrel made of metal is made by rotating the device in a rotating device, exposing a portion to be coated, and then spraying nickel powder on the surface of the roller mandrel using a thermal spraying gun, and secondarily, high purity chromium oxide. By spraying powder coating, a double coating layer is formed and the surface is polished to obtain a finished product.
이를 공정별로 설명하면 다음과 같다.This will be described by process.
제1공정1st process
금속제 로울러 심봉(1)을 초음파 세척기에 넣고 세척하여 표면의 불순물과 기름 등을 제거한다.The metal roller mandrel (1) is placed in an ultrasonic cleaner and washed to remove impurities and oil from the surface.
제2공정2nd process
로울러심봉 표면에 BLASTING을 실시하여 세척하고 마스킹작업을 한다.Blasting on the surface of roller core rod is used for cleaning and masking.
제3공정(코팅공정)3rd process (coating process)
1차로 니켈 80%, 알루미늄 18%, 기타 2%로 조성된 니켈파우다를 용사건에 넣고 용사속도 마하 2이상, 용사온도 16,500℃로 용사코팅하고 2차로 Cr2O396%, TiO22%, 산화물 2%로 조성한 산화크롬분말을 용사건에 넣고 용사속도 마하 2이상 용사온도 16,500℃로 용사코팅 한다.First, nickel powder made up of 80% nickel, 18% aluminum, and 2% of other metal powder is added to the thermal spraying gun. The thermal spraying coating is carried out at a spraying speed of Mach 2 or higher and the thermal spraying temperature of 16,500 ℃. Secondly, Cr 2 O 3 96%, TiO 2 2% , Chromium oxide powder composed of 2% of oxide is placed in the spraying gun and sprayed at a spraying speed of Mach 2 or higher at a spraying temperature of 16,500 ° C.
이때, 사용되는 가스는 Ar.99.999이상(UPC)At this time, the gas used is Ar.99.999 or more (UPC)
H2.99.999이상(UPC)H2.99.999 or higher (UPC)
제4공정4th process
마스킹제거 및 씨링처리를 한다.Remove masking and seal.
제5공정5th process
코팅된 제품을 건조로에 넣고 100℃에서 8시간 이상 건조시킨다.The coated product is placed in a drying furnace and dried at 100 ° C. for at least 8 hours.
제6공정(표면연마)6th process (Surface polishing)
다이아몬드칼을 사용하여 1차 220멧쉬로 횡삭하고, 2차 350-600멧쉬로 정삭하여 분쇄로울러를 완성시킨다.The diamond knife is used to cross the first 220 meshes and the second 350-600 meshes to complete the grinding roller.
본 발명에 의하여 코팅되는 두께는 1차,2차 합하여 0.5mm정도이다.The thickness coated by the present invention is about 0.5mm in the first and second sum.
이와 같이 제조된 본 발명은 금속제 로울러 심봉(1) 표면에 1차로 니켈이 주제인 니켈파우다가 용사코팅되고 2차로 산화크롬분말이 주제인 고순도 산화크롬분말을 용사코팅하여 강력한 내마모성의 산화방지막을 형성하였기 때문에 분쇄기에 설치하고 고추나 농산물을 가루로 만들기 위해 분쇄작업을 실시하면 쇳가루가 발생될 염려가 없으며 표면에 녹이 슬지 않아 농산물을 정갈하게 분쇄할 수 있고 위생적으로 가공할 수 있는 효과가 있을 뿐 아니라 전체가 세라믹 덩어리로 된 종래의 로울러와 비교하여 내충격적이고 가격도 염가로 되기 때문에 실용성과 경제성을 높일 수 있는 이점을 얻게 되고 산화크롬분말 용사코팅층 내면에 크롬분말용사코팅층이 있어서 모재와의 접착이 완벽하면서 완충작용이 양호하므로 분쇄작업 중에 가해지는 충격을 적절히 완충하면서 분쇄작용을 하게 되어 내구적인 로울러를 유지하게 되는 등의 장점을 얻고 코팅 후 장시간 열처리하여 경화시키기 때문에 내구적인 로울러를 얻는 것이다.The present invention prepared as described above forms a strong wear-resistant anti-oxidation film by thermally spraying high purity chromium oxide powder, which is primarily nickel powder coated with nickel powder on the surface of the metal roller core rod 1, and secondly coated with chromium oxide powder. Since it is installed in a grinder and pulverized to make red pepper or agricultural products into powder, there is no fear of crushing powder, and there is no rust on the surface so that agricultural products can be neatly crushed and sanitized. Compared with the conventional roller made of ceramic agglomerate, it is more impact-resistant and inexpensive, so it has the advantage of increasing practicality and economical efficiency. It has a good buffering effect and reduces the impact on grinding It is a durable roller because it is hardly buffered and obtains the advantages of maintaining a durable roller and hardening by heat treatment for a long time after coating.
