Abstract

Представлены способ и устройство для обработки пластмасс. Согласно способу исходный пластмассовый материал подается в зону подачи одношнекового экструдера, из зоны подачи материал перемещается в зону сжатия, в которой данный материал плавится для образования расплавленной пластмассы, после чего расплавленная пластмасса через зону дозирования подводится к рабочему инструменту, который формирует пластмассовое изделие. В зоне подачи расположена часть вала, содержащая канавки, и по меньшей мере рассмотренная в целом цилиндрическая подающая втулка, на которой расположены направляющие, перемещаемая параллельно своей продольной оси и/или вращаемая вокруг своей продольной оси в течение регулировки технологической обработки при подаче пластмассового исходного материала в экструдер так, чтобы создавался равномерный поток исходного материала.
