摘要： An object is to reduce a weight of a raw material to be used for manufacturing a screw shaft by combining a tapered section and a tapered ring as a structure of a flange section. A screw shaft structure for a twin screw extruder includes a tapered section (20) provided between a ground section (6) and a screw piece inserting section (8), and a tapered ring (21) fitted onto the tapered section (20), the tapered ring (21) serving as a flange section.

摘要： A channel is sufficiently limited, and thereby a sufficient range for adjusting the degree of kneading is ensured. Two screws is rotatable around first axes of rotation. A pair of gate rods 5 that sandwich two screws 4 and that are opposite to each other is provided. The gate rods are rotatable around second axes of rotation A2. Each of the pair of gate rods has two recess parts 9, and recess parts 9 that are opposite to each other form respective spaces through which the two screws penetrate. Each of the pair of gate rods 5 has first contact surface 21 that comes into surface contact with screw 4 when gate rod 5 is rotated to a minimum degree-of-opening position where an area of a channel that is formed between gate rod 5 and screw 4 is minimized, large diameter part 24, 27 that are fitted into the groove of cylinder 4, and small diameter part 25 having a radius of curvature that is equal to half a distance between two second axes of rotation A2 and that is smaller than a radius of curvature of the large diameter part 24, 27. Small diameter parts 25 of the pair of gate rods are in contact with each other.
摘要翻译：通道被充分限制，从而确保了用于调节捏合程度的充分范围。两个螺钉可围绕第一旋转轴旋转。提供了夹着两个螺钉4并且彼此相对的一对门杆5。门杆可围绕第二旋转轴线A2旋转。一对门杆中的每一个具有两个凹部9，并且彼此相对的凹部9形成两个螺钉穿过的相应空间。当门杆5旋转到最小开启位置时，一对门杆5中的每一个具有第一接触表面21，所述第一接触表面21与螺钉4进行面接触，在所述最小开启位置处，门杆5与门杆5之间形成的通道的区域螺钉4被最小化，嵌入圆柱体4的凹槽中的大直径部分24,27以及具有等于两个第二旋转轴线A2之间的距离的一半的曲率半径的小直径部分25，大直径部分24,27的曲率半径。一对门杆的小直径部分25彼此接触。
