な混練が行われなかつた。(Prior art) In conventional continuous kneading equipment of this type, the distance between the two rotors is either larger than the outer diameter of the rotor, or the distance between the two shafts is smaller than the outer diameter of the rotor, so that the loci of the rotors are mutually inconsistent. Even when they intersect, the structure is such that the angular velocity of the rotor shaft and the circumferential velocity of the rotor are equal to each other. In the former case, the materials were mainly kneaded between the inner wall surface of the container and the rotor, and a relatively wide space was formed between the rotors, so this part hardly contributed to the kneading. Also,
In the latter case, it is thought that the larger the area where the two rotors intersect, the more this area contributes to kneading, but since the peaks or troughs of both rotors move in the same direction at approximately the same speed, was not sufficiently kneaded.

The number of threads is different from each other, and in the embodiment, the first rotor 9A has three threads, and the second rotor 9B has four threads.
Therefore, the cross-sectional shape in any cross section is the fourth
As illustrated in each figure, 3 are equally distributed on the circumference.
The ridges of the first rotor 9A, which has four ridges, and the second rotor 9B, which has four ridges evenly distributed on the circumference, are engaged with each other, and the ridges of the first rotor 9A, which has four ridges, are engaged with each other. Rotate in the direction. 9A, 9 of this two-axis rotor
When the outer diameters of B are D 1 and D 2 and the distance between the shafts is A, A is smaller than 1/2 (D 1 + D 2 ), and as a result, the outer diameters of both rotors D 1 and D 2 are The trajectories intersect with each other. Also, the diameter of the valley formed between the mountains
If d 1 and d 2 , 1/2 (d 1 + D 2 ) and 1/2
Both (D 1 +d 2 ) are slightly smaller than the distance A between the axes, and as a result, opposing peaks and valleys are close to each other on the center line connecting the axes. Rotor 9A, 9
The lead angle of the helix of B can be varied continuously or discontinuously. In the embodiment, the advance angle is small for a while from just below the material input port 2, forming a supply section for feeding the material, and the winding direction is reversed at a point slightly past the midpoint, and the advance angle is large before and after that. , forming a kneading section for kneading materials.

繰り返し実行されて混練効果が向上する。 Furthermore, according to the present invention, the distance A between the shafts of the two-shaft rotor is smaller than the sum of the radii of the crests of the rotor, and the trajectories of the outer diameters intersect, so that the two shafts face each other on the center line connecting the shaft centers. The peaks and valleys are close to each other, and the space formed above and below the center line is divided into two at the closest point on the center line, and
Due to the difference in the circumferential speed of both rotors,
At one moment, the upper space is wide and the lower space is narrow, but at the next moment, the upper space is narrow and the lower space is wide, and there is an extremely narrow bottleneck between the two spaces, which causes the material to deteriorate. The kneading effect is improved by repeatedly compressing and shearing the material.
