As is known, a continuous mixing machine is used that continuously feeds, kneads, and discharges materials, and there are two types: a single-shaft type and a two-shaft type.
Although there is a axial type, a two-shaft type continuous cross-mixer is generally used in many respects, such as shear effect, cross-wire effect, and melting of materials due to shear heat. The general form and function of the continuous mixed wire type is that two rotors are installed in parallel and opposite directions (the same direction is also possible) in a chamber that is equipped with a material supply at one end and a kneaded material discharge port at the other end. ), a screw-shaped feed portion is provided to obtain a helical groove for feeding the material to the rotor, and a screw-shaped feed portion is provided which is subsequently twisted to feed the material forward. A kneading blade is provided on the surface, in which a feeding blade that has been twisted and a return blade that is twisted to return the material are formed in a series over the length direction, or a kneading blade is formed in a divided and joined shape by shifting in the circumferential direction. By providing a mixing section, a feed chamber and a kneading chamber are continuously configured between the chamber. In addition, as a modification, a discharge section is provided behind the return blade. A straight discharge vane is provided on the peripheral surface corresponding to the discharge section at the rear end of the rotor, and further, a straight discharge blade is provided on the circumferential surface corresponding to the discharge section at the rear end of the rotor. Some types have a conical portion formed on the surface and a slot portion that is variable between both cones by moving the rotor forward and backward.

いられることも既知である。As a result, the material introduced into the feed section through the material supply port in the chamber is sent through the feed section to the mixing section, and through the rotation of the kneading blades, it passes through the gap between the blade tip and the inner surface of the chamber. In addition to receiving a new action, the material is plastically melted due to shear heat, and the desired crosstalk is obtained by dispersion by movement in the forward and backward directions by the sending and returning blades and the transfer of material between two parallel axes. It is. In this case, as is known, the axial force exerted on the material by the kneading vanes in the mixing chamber is not sufficient to push the material out of the outlet in the chamber, and the material moves through the mixer towards the outlet. The flowing discharge speed is dependent on the introduction speed of the crosstalk material introduced from the feed section. For this reason, in this type of continuous twin-screw mixing system, as a means to supplement its discharge capacity, it is necessary to install a screw extruder in communication below the discharge section of the kneader, and furthermore, to replace the screw extruder with a variable speed It is also known to use means of installing a gear pump driven by a motor.

備えた点にある。The present invention has been made in order to solve the problems that occur in the conventional type of continuous kneading machine, especially the type in which a gear pump is provided in communication with the kneading machine discharge part, and its characteristics are as follows. The part includes a feed part communicating with a feeder for automatic feeding of materials to be mixed, a mixing part equipped with at least rotating kneading blades, a discharge part equipped with a pressure sensor, and a fixed volume communicating with the discharge part. In a continuous kneading and extrusion device, the kneading material discharge rate depends on the introduction speed of the material to be mixed into the feed section, the kneading material production amount in the device is controlled by the gear pump rotation speed, and the kneading material discharge rate is The pressure adjustment in the section is adjusted by the amount of material fed from the feeder, and its feature is that in addition to the above features,
The discharge part is equipped with a pressure sensor and a means for closing the discharge part.

。In other words, the materials kneaded by this type of continuous mixing machine do not become finished products as they are, but are used as raw materials for various molded products such as beletizers, granular molded products, sheet-shaped molded products, pipe-shaped molded products, etc. The mixed material discharged from the discharge section of the mixer by a gear pump is usually sent directly to the respective molding plant. At this time, the discharge speed (moving speed) of the material to be mixed in the continuous kneader depends on the speed at which the material to be mixed is introduced into the feed section of the mixer. Because it has the characteristic that only discharge can be obtained,
The gear pump in the discharge section of a conventional continuous kneader is
If the mixer is rotated at variable speeds depending on the degree of material filling in the mixer, the pump discharge volume will fluctuate depending on the rotational speed, which deteriorates the dimensional accuracy of the molded product in the pellet die, sheet die, etc. in the molding plant to which it is supplied. In addition, in order to accurately maintain the filling level of the material, there are problems such as the need to use an expensive gravimetric feeder as a feeder for supplying the material to be mixed to the feed section of the mixing machine.
