Description

압출기의 압출물 자동 컨베이어장치{Auto conveyer apparatus for discharging extruding material}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic conveyor apparatus for discharging extruding material,

본 발명은 압출기의 압출물 자동 컨베이어장치에 관한 것으로써, 특히 압출된 압출물의 배출속도를 향상시키고 연속공정을 수행할 수 있도록 한 압출기의 압출물 자동 컨베이어장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic conveyor apparatus for an extruded product of an extruder, and more particularly, to an extruded automatic conveyor apparatus of an extruder capable of improving a discharge speed of an extruded extrudate and performing a continuous process.

고무계 조성물로 이루어지는 원료를 혼련하여 균일한 상태로 처리하기 위해서는, 2축 혼련 압출기를 이용하는 것이 일반적이다. In order to knead a raw material comprising a rubber-based composition and treat it in a uniform state, a twin-screw kneading extruder is generally used.

즉, 좌우 한 쌍의 회전 스크류를 서로의 블레이드가 부분적으로 서로 인입하는 상태로 근접시켜 배치하고, 이들 스크류로 고무재를 혼련하면서 이동시켜 종단부에 배치된 다이로부터 압출하도록 구성하고, 압출되는 압출물을 일정길이로 절단하여 배출컨베이어로 배출하는 압출기를 이용한다. That is, a pair of left and right rotating screws are arranged in such a manner that the blades of the left and right sides are partially brought close to each other, and the rubber material is kneaded while being kneaded by these screws and extruded from a die arranged at the longitudinal end. An extruder for cutting water to a predetermined length and discharging it to a discharge conveyor is used.

그런데 통상적인 배출컨베이어는 고정위치에 고정된 구조로 되어 있어서, 배출컨베이어로 배출된 압출물이 다른 장소로 이동되지 아니한 상태에서는 다이를 통한 압출물의 연속 배출을 정지시켜야 한다.However, a conventional discharge conveyor has a structure fixed to a fixed position, so that the continuous discharge of the extrudate through the die must be stopped when the extrudate discharged by the discharge conveyor is not moved to another place.

따라서 연속 공정을 수행하기 위하여는 배출컨베이어로 배출된 압출물을 즉시 다른장소로 이동시켜야 하는 번거로움이 수반된다.Therefore, in order to carry out the continuous process, it is necessary to move the extrudate discharged by the discharge conveyor immediately to another place.
