본 고안은 석유화학공장에서 압출도니 합성수지제품을 입자상으로 전달하는 로타리 커터에 관한 것이다.The present invention relates to a rotary cutter that delivers extruded plastic resin products in the form of particles in a petrochemical plant.

종래의 로타리 커터는 제3도 및 제4도에 도시한 바와같이 원통형 금속체(1)의 외주면에 회전톱날과 같은 절단날(2)을 일정한 간격으로 삭설한 것으로서 절단날(2)부위가 마모되면 날이 예리하게 연마하여야 하는데 이때마다 기체로부터 커터를 분리하여야 하는 작업상의 어려움이 있었고, 그것도 2차연마 후에는 커터 전체를 폐기처분하여야 하는 작업시간상의 손실과 소모성 커터 비용이 막대하게 들어가는 실정이었다.In the conventional rotary cutter, as shown in FIGS. 3 and 4, the cutting edge 2 such as a rotary saw blade is cut at regular intervals on the outer circumferential surface of the cylindrical metal body 1, and the cutting edge 2 is worn out. In this case, the blade should be sharply sharpened, and there was a difficulty in separating the cutter from the gas at each time. Also, after the second polishing, the time required for the disposal of the cutter and the disposal of the cutter were greatly incurred. .

더욱이 작업중에는 철사 혹은 공구등이 들어갈 때 날의 일부가 파손되는데 이러한 경우에는 로타리 커터 전체를 교체하지 않으면 안되기 때문에 이에 따른 커터비, 커터의 교체시간 동안 생산라인 전체가 모두 정지되는 생산상의 손실이 극심한 것이었다.In addition, some of the blades are damaged when wires or tools enter during operation. In this case, the entire rotary cutter has to be replaced. Was.

이와같은 종래 커터의 문제점을 해결할 수 있게 안출된 본 고안은 커터의 본체는 반영구적으로 사용할 수 있고 날의 마모 및 파손시에는 커터를 분리하지 않고 부분 교체를 가능케 신속한 작업을 할 수 있도록 절단날을 조립식으로 구성한 것인데,The present invention devised to solve the problems of the conventional cutter can be used semi-permanently the main body of the cutter, and when the blade wear and breakage, the cutting blade is assembled so that the parts can be replaced quickly without removing the cutter. It is composed of

이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

다각 원통형 금속체(11)의 외주면에 일정한 간격으로 다각면부(15)(15')를 형성하고 이에 긴홈(12)을 비스듬하게 형성하되 이 홈(12)의 좌벽면(13)은 금속체(11)의 중심지름선상(14)과 평행선상으로 형성되고 우벽면(16)은 그 상하단부가 중심지름선상(14)에 대하여 상협하광형의 경사성산으로 형성되어 있다. 한편, 홈(12)의 내면(17)에는 일정한 간격으로 나사구멍(18)이 형성되고 상기 좌벽면(13)과 우벽면(16)에 밀착되는 특수강금속성 칼날(19)(20)을 밀착한 후 상광하협형 고정구(21)를 대고 나사못(22)으로 조요서 양칼날(19)(20)이 협지되게 한 구성이다.Polygonal surface portions 15 and 15 'are formed on the outer circumferential surface of the polygonal cylindrical metal body 11 at regular intervals, and long grooves 12 are obliquely formed thereon, and the left wall surface 13 of the groove 12 is formed of a metal body ( It is formed in parallel with the center diameter line 14 of 11), and the right wall surface 16 is formed by the sloped mountain of the upper and lower light type with respect to the center diameter line 14 in the upper and lower ends. On the other hand, the inner surface 17 of the groove 12 is formed with a screw hole 18 at regular intervals and the special steel metallic blades 19 and 20 in close contact with the left wall surface 13 and the right wall surface 16 in close contact with each other. After the up-and-down downside fixture (21) is a configuration that allows the two blades (19) (20) to be clamped with a screw (22).

이와같이 구성된 본 고안은 칼날(19)(20)이 마모되거나 파손되면 금속체(11)를 분리하지 아니하고도 나사못(22)을 풀고 칼날(19)(20)을 새것으로 신속 간편하게 갈아끼울 수 있는 것이기 때문에 금속체(11)를 반영구적으로 사용할 수 있는 효과가 있고 칼날의 부분 교체로 인한 수리비가 저렴하며 그 적업시간도 신속하여 종래와 같이 수리할 동안 생산라인 전체가 스톱되는 기간을 최소화할 수 있는 효과가 있다.When the blades 19 and 20 are worn or damaged, the present invention configured as described above can loosen the screw 22 and replace the blades 19 and 20 quickly and easily without removing the metal body 11. Therefore, the metal body 11 can be used semi-permanently, and the repair cost is low due to the partial replacement of the blade, and the working time is also fast, so that the entire production line can be minimized during repair as in the prior art. There is.
