Abstract: 소재 이송량 조절장치를 개량하여 소재의 이송량 변화에 따라 신속하게 회전축의 회전비를 변화시킬 수 있게 하고, 소재의 중량 변화에 따라 이송량을 용이하게 조절시킬 수 있게 하는 소재 이송량 조절장치에 관한 것이다. 
     종래에 있어서의 소재 이송량 조절장치는 가동롤이 힌지축을 중심으로 회동되는 링크의 일단에 설치되고, 링크의 또 다른 단부에는 추가 설치되어 구성되는 것으로, 이와 같은 종래의 소재 이송량 조절장치는 소재의 이송량 조절시 링크에 결합된 가동롤이 선회되면서 이동됨에 따라 이송량 조절을 신속하게 할 수 없는 문제점이 있었던 바, 본 발명은 소재의 이송량 조절장치(2)를 구성함에 있어서, 롤장치(1)에 연결되는 바(20)와; 상기 바(20)에 일정한 간격으로 이격 설치되는 한쌍의 고정롤(21)(22)과; 상기 바(20)에 설치되는 가이드(23)와; 상기 가이드(23)를 따라 상하로 이동 가능하게 설치되는 이동축수(24)와; 상기 이동축수(24)에 설치되는 가동롤(25)과; 상기 가이드(23)에 설치되어 이동축수(24)의 상/하 이동에 따라 롤장치(1)의 모터(10) 회전비를 제어하는 회전제어장치(3)를 설치시켜 구성됨으로써, 소재의 이송량 변화에 따라 신속하게 회전축의 회전비를 변화시켜 이송되는 소재가 과도하게 이송되어 지면에 닿는 다거나 심하게 당겨져 장치에 과부하가 걸리는 문제점을 해결할 수 있으며, 소재의 중량 변화에 따라 소재의 이송량을 용이하게 조절시킬 수 있는 효과가 있는 것임.
