  However, since the quality of the clay in ceramics largely depends on the uniformity of the clay kneaded through the kneader, the kneading work is repeatedly performed several times in the clay kneader in order to further homogenize the clay. In some cases, there was room for improving the clay kneading ability.

  Therefore, an object of the present invention is to provide a kneader capable of improving the kneading ability of clay and, in turn, obtaining a high-quality clay for ceramics without repeating the kneading operation.

The invention according to claim 1, which has been made to achieve this object, has a kneading chamber for kneading clay therein, has an opening hole for pouring clay toward the kneading chamber in its peripheral wall, and contains clay. A casing provided with a discharge port for discharging from the kneading chamber, and the discharge port disposed in the kneading chamber, rotating around its own axis, and kneading clay with a spiral blade member protruding on the peripheral surface A kneading shaft that presses the kneading shaft and a drive source for rotationally driving the kneading shaft, the nozzle connecting the kneading chamber and the discharge port at one end of the casing The kneading shaft presses the clay put into the kneading chamber through the opening hole toward the discharge port through the nozzle, and the blade member is kneaded to the kneading shaft. A partition member for partitioning in the axial direction of the shaft is connected to the kneading shaft. Provided integrally with a larger outer diameter than the diameter of parts, said blade member, said through the partition member is divided into a blade portion of the upstream side and the downstream side of the blade portion in the discharge direction of the clay It is comprised, The extrusion path by which clay is extruded from an upstream to the downstream is provided between the outer periphery of the said partition member, and the inner periphery of the said casing, It is characterized by the above-mentioned.

According to the earth kneader according to claim 1, the kneading shaft is integrally formed with the partition member for partitioning the blade member in the axial direction of the kneading shaft and having an outer diameter larger than the diameter of the shaft portion of the kneading shaft. The blade member is configured to be divided into an upstream blade portion and a downstream blade portion in the clay discharge direction via the partition member, and between the outer periphery of the partition member and the inner periphery of the casing. Since the clay is provided with an extrusion path through which the clay is extruded from the upstream side to the downstream side, the kneading ability can be improved, and thus a uniform clay can be obtained even if the number of times of kneading is small.

That is, according to the mainland kneader, during the kneading, the clay extruded from the upstream side while spirally turning along the kneading shaft has an axial compression resistance in the vicinity of the partition member. It is pushed downstream through the extrusion path constituted by the outer periphery of the receiver and partition member and the inner periphery of the casing. At this time, due to changes in the clay outflow direction, axial speed change, compressive force applied to the clay, etc. Kneading is further promoted. Further, since the partition member rotates together with the kneading shaft, when the clay passes through the extrusion path, a relative speed difference is generated between the clay passing through the casing inner peripheral side and the clay passing through the partition member side. Kneading is promoted.

To do.

  Moreover, according to the kneading machine 1 described in the embodiment, since the kneading shafts 10 and 11 are provided, the clay discharge capacity is higher than that of any one of the kneading shafts 10 and 11. Can be improved. Further, the blade portions 10a, 10b, 10c, and 10d provided on the kneading shaft 10 and the blade portions 11a, 11b, 11c, and 11d provided on the kneading shaft 11 are bordered on the line XX shown in FIG. Are formed so as to be symmetrical with each other, and the tip end side in the radial direction of each blade portion is overlapped in the X direction, so that the kneading ability can be obtained satisfactorily.

Moreover, according to the kneading machine 1 described in the embodiment, since the partition member 5 and the casing 8 have different materials or surface roughness, the inner wall side of the casing 8 when the clay passes through the extrusion path Q is provided. A relative speed difference is more easily generated between the passing clay and the clay passing through the partition member 5 side, and kneading is promoted.

  Moreover, according to the clay kneader 1 described in the embodiment, the partition member 5 has a length corresponding to the swirl in which the thickness t is approximately a half of the blade member in the axial direction of the kneading shafts 10 and 11 (FIG. 4). By being formed in 1/2 of the reference sign S in the middle, the clay kneading ability and the discharging ability through the extrusion path Q can be obtained satisfactorily.
