摘要： A plasticating apparatus including a rotating screw having a helical flight disposed within and cooperating with the inner wall of a heated barrel. Solid resinous material is introduced to a helical valley extending between said flight to be heated and plasticized by said apparatus while being advanced towards an outlet opening by the rotation of said screw. The screw has a meter section for working, melting and mixing said resinous material at high temperatures. The bottom surface of the helical valley in said metering section is divided into side by side relatively shallow and relatively deep levels. Within the metering section is a transit channel having a reverse helical direction as compared with the helical direction of the flight. Because of the reverse helical direction of the transit channel, the transit channel intersects the helical flight and helical valley with the transit channel cutting therethrough. During operation, the level differential between the shallow and deep levels induces a continuous tumbling and mixing action upon the molten resin while the transit channel allows portions of the molten resin to back flow and recirculate through the mixing section.
摘要翻译：一种塑化装置，其包括旋转螺杆，该旋转螺杆具有设置在加热筒的内壁内并与加热筒的内壁配合的螺旋状飞行。将固体树脂材料引入到所述待加热的飞行物之间延伸并且由所述设备塑化的螺旋谷物，同时通过所述螺杆的旋转朝向出口开口前进。螺杆具有用于在高温下加工，熔化和混合所述树脂材料的仪表部分。所述计量部分中的螺旋谷的底面被分为相对较浅和相对较深的并排。在计量部分内是与飞行的螺旋方向相比具有相反螺旋方向的运输通道。由于运输通道的反向螺旋方向，运输通道与螺旋螺旋和螺旋谷相交，而运输通道切断。在操作期间，浅层和深层之间的水平差异引起对熔融树脂的连续翻滚和混合作用，而中转通道允许熔融树脂的一部分回流并再循环通过混合段。
