自从螺旋式挤出机发明以来，陶瓷行业已经发展出了一个庞大的业务，致力于生产各种类型和尺寸的挤出机。在此期间，关于为特定工作设计螺旋轴、模具和机器的大量经验知识已经积累起来。到目前为止，还没有一种方法可以为螺旋轴的设计参数赋值，从而能够合理地确保它能够挤出一种其塑性特性已知的材料。本文提出了一个螺旋轴对材料作用的模型，并将有机热塑性挤出机中固体的螺旋输送理论应用于对该模型的研究。还讨论了描述特定挤出机对塑料材料作用的特征函数的概念。
Since the invention of the auger-type extrusion machine, there has developed a large business devoted to the production of extrusion machines of various types and sizes for the ceramic industry. During this time, a vast body of empirical knowledge concerning the design of augers, dies, and machines to do particular jobs has grown. As of today, no method has been proposed by which values may be assigned to the design parameters of an auger so that there may be reasonable assurance that it will extrude a material, the plastic properties of which may be known. This paper proposes a model for the operation of an auger on a material and adapts the theory of the screw conveying of solids in organic thermoplastic extrusion machines to the study of this model. The concept of the characteristic function, which describes the action of a particular extruder on a plastic material, is discussed.
