るなどの諸欠点があった。<Prior art> In a conventional cone type extruder, large bevel gears provided at the base of each rotor shaft are meshed with each other, and a small drive bevel gear for transmitting power is mounted on one of the rotor shafts. The structure of the bevel gear meshing with the large bevel gear requires three-axis alignment, which is not only difficult to design and manufacture, but also causes slight displacement of the rotor shaft in the axial direction due to wear during use. There were various drawbacks, such as the meshing relationship of the gears being thrown out of order just by doing so, requiring readjustment.

また、コーン型押出機のロータ軸回転速度は通常弗素に
低速であって、そのため、モータ等と上記傘歯車の間に
減速機を必要とした。Further, the rotational speed of the rotor shaft of a cone type extruder is usually low compared to fluorine, and therefore a reduction gear is required between the motor etc. and the bevel gear.

投入口を大きくするためである。The extruder container 1 has a double cone shape with a tapered tip,
A material input port 2 is opened above the base, and a discharge port 3 is opened at the tip. The rotors 4 and 5 rotating in this container are supported by bearings 6 and 7 and bearings built into the worm reducer 8.9, and a rotor rigid joint 1011 is provided at the tip of the rotor 4, which passes through the inside of the worm reducer 8.9. A flow path for circulating cold water or hot water is perforated in the rotor shaft core. A ribbon-type stirrer 12.13 is provided at a portion of the rotor 4.5 directly below the material input port 2, and a helical-type plaid 14.15 is provided at the tip thereof. In this way, there is no helical shaped plaid throughout the entire inside of the container,
The reason for using a ribbon-type stirrer for the material input section is that when the already kneaded materials are introduced, they are not over-kneaded, thereby eliminating unnecessary load and reducing driving torque.
This is to enlarge the input port.

Therefore, by fitting the base of the rotor shaft 4 or 5 into the through hole of the worm gear 23 and fixing the housing 29 to the frame 30 of the extruder with bolts or the like,
The rotor shaft 4 or 5 has a bearing 6 or 7 in the frame and a bearing 24 or 25 built in the worm reducer 8, 9.

In that case, it is preferable to tilt the rotor axis to such an extent that the bottom of the container 1 is slightly tilted in the direction in which the tip is directed downward.

可能になった。<Effects of the Invention> According to the present invention, it is only necessary to attach the worm reducer, whose inter-shaft relationship is precisely adjusted in advance and housed in the housing, to the base of the rotor shaft, so the structure is extremely simple.
In addition, manufacturing and adjustment work has become easier, and manufacturing costs have been significantly reduced. In addition, the same worm reducer can be used for products with slightly different rotor distances and angles, making it possible to use mass-produced worm reducers. Since it is not necessary, the configuration is extremely simplified and costs can be reduced significantly.

It becomes easy to cool or heat the rotor shaft.
