Patent ID: 7918662

Claim:
An integrated apparatus having a kneading part and an injecting part, the kneading part comprising: a kneading screw shaft; a kneading shaft drive unit for driving rotation of the kneading screw shaft; and a kneading barrel, in which the kneading screw shaft is rotatably inserted and placed, and kneading of a material is performed by rotating the kneading screw shaft, and which continuously quantitatively feeds the kneaded material from a kneaded material feed throat at a tip end thereof, the injecting part comprising: an injection screw shaft; an injection shaft drive unit for rotatably driving the injection screw shaft and driving advancing and retreating movements along an axial direction of the injection screw shaft; and an injection cylinder, in which the injection screw shaft is inserted and placed rotatably with a capability of advancing and retreating along an axial direction thereof, and a communication port and an injection port are formed, the communication port being formed so as to communicate with the kneaded material feed throat of the kneading barrel and receive the fed material in a kneaded state, and the injection port being formed so as to permit injection of the material weighed by the screw shaft therefrom, wherein the injection screw shaft located in the injecting part, comprises: a weighing screw channel portion for weighing the material by rotational driving amount of the injection screw shaft and loading the material into a material loading space formed on a forward side by retreating movement of the injection screw shaft; and a retention screw channel portion which is formed adjacently to the weighing screw channel portion so that a channel shape thereof is different and forms a material retention space for retaining the material fed continuously quantitatively from the kneading part.
