By positioning the blade for the purpose of pushing back between the blade on the side and the blade on the side of the discharge port exclusively for discharge, the process from kneading to discharge can be performed smoothly.

  The kneader according to the present invention will be described in detail with reference to the drawings. In FIG.1 and FIG.2, the code | symbol 10 shows the kneading machine 10 of this invention. This clay kneader 10 includes a kneading chamber 16 having a pottery soil inlet 12 and a discharge port 14 and a kneading jig 18 that is rotated in the kneading chamber 16 to knead while feeding the pottery soil. .

  The kneading jig 18 includes screw-shaped first blades 20 (a) and 20 (b) for feeding the ceramic soil toward the discharge port 14, and a screw-shaped second blade 22 for pushing the ceramic soil in the reverse direction. It has. One kneading jig 18 includes first blades 20 (a) and 20 (b) and a second blade 22 around one rotating shaft 24. Two pairs are provided so as to be rotated in opposite directions. Due to the gear mechanism 25, the first blades 20 (a) and 20 (b) and the second blade 22 of the two kneading jigs 18 are screwed in opposite directions. The second blade 22 is located between the first blade 20 (a) on the charging port 12 side and the first blade 20 (b) on the discharge port 14 side, and the first blades 20 (a) and 20 It has a screw shape opposite to (b). The height of the second blade 22 from the periphery of the rotation shaft 24 is ½ of the height H of the first blade. The length of the second blade 22 in the rotation center axis direction is ½ of the length of one pitch P of the first blade 20 (a).

  The first blade 20 (a) of the kneading jig 18 is configured by combining three parts 26 (a), 26 (b) and 26 (c) as shown in FIG. The first blade 20 (b) is configured by combining two parts 26 (d) and 26 (e). The second blade 22 is composed of one part 28. These parts 26 (a), 26 (b), 26 (c), 26 (d), 26 (e) and 28 are fitted to the rotary shaft 24 as shown in FIG. 18 is assembled.

  The operation of the kneader 10 and the kneading jig 18 will be described below.

  For example, when kneading two types of earthenware using the kneader 10, two types of ceramics are driven in a state where two kneading jigs 18 are rotated in opposite directions by driving a motor (not shown). The soil is simultaneously charged into the kneading chamber 16 from the charging port 12. Since the blade 20 (a) is rotating, the two types of earthenware are drawn into the kneading chamber 16 by the blade 20 (a).

  The two types of earthenware soil drawn in are fed toward the discharge port 14 while being kneaded by the blade 20 (a). As shown by the arrow in FIG. 4, the clay for earthenware sent to the discharge port 14 is returned to the input port 12 side by a screw-shaped blade 22 opposite to the blade 20 (a). The returned earth for pottery collides with the earth for pottery sequentially fed toward the discharge port 14 by the blade 20 (a). That is, while the earthenware for earth is pushed back with the force of N2 in the direction of θ2 with respect to the cut surface of the rotating shaft 24, the earthenware for earthenware is sequentially sent in the direction of θ1 with the force of N1 and collides and presses against each other. Become. Depressed by squeezing each other. The collapsible earthenware is fed from the gap 30 around the blade 22 toward the blade 20 (b).

  The clay for earthenware sent to the blade 20 (b) is sent toward the discharge port 14 by the rotating blade 20 (b) and is discharged from the discharge port 14. It is preferable that the discharged pottery earth is again charged into the charging port 12 and kneaded again. Thus, as a result of actually kneading two kinds of pottery soils of red pottery soil and gray pottery soil, if they were kneaded three times, they were completely mixed and no spotted pattern was generated. In addition, when the blade 22 was removed and tested with the same pottery soil, a mottled pattern was generated even after kneading three times. In addition, air holes were not generated in the baked product after completely deaerated and baked.

  According to the clay kneader 10 of the present invention, the earthen for earthenware is once pushed back by the blade 22 and pressed against the earthenware for earth sent from the blade 20 (a), and the earth for earthenware is sent to the discharge port 14 through the gap 30. It can be uniformly kneaded and deaerated. That is, an excellent effect is generated by the synergistic effect of the blade 22 and the gap. In addition, when the length of the second blade 22 in the rotation center axis direction is about ½ of the length of one pitch P of the first blade 20 (a), an excellent effect is actually produced. .

  In addition, since both the first blade 20 and the second blade 22 are provided around one rotating shaft 24, the earthenware for sending to the discharge port 14 along the one rotating shaft 24, The ceramic blade to be returned along the rotary shaft 24 can be directly pressed by the second blade 22. On the other hand, since two pairs of kneading jigs 18 that are rotated in opposite directions are provided, the clay for soil to be returned by the second blade 22 of one kneading jig 18 is transferred to the first kneading jig 18. It can also be pressed against the earth for pottery sent by the blade 20 (a). For this reason, the flow of one pottery soil collides with a plurality of flows of pottery soil, and the flow of the pottery soil is complicated and can be kneaded efficiently.

  Further, according to the kneading machine 10 of the present invention, when the earth for pottery is solidified once stopped, the earth for pottery is pushed back by the blade 22 and moved. . For this reason, for the convenience of work, even when the kneader 10 is stopped, the work can be returned quickly.

  Further, since the second blade 22 is located between the first blade 20 (a) and the first blade 20 (b), the second blade 22 exclusively discharges with the blade 20 (a) for the purpose of kneading the clay for earthenware. By positioning the blade 22 for the purpose of pushing back between the target blade 20 (b), the process from kneading to discharging can be performed smoothly. That is, after kneading sufficiently with the blade 20 (a) and the blade 22, the blade 20 (b) can be discharged efficiently.

  As mentioned above, although one embodiment of the kneading machine of this invention was described, this invention may be other embodiment.

  For example, the kneader 10 may include two blades 22 for one kneading jig 18 as shown in FIG. The blade 22 on the tip side of the rotating shaft 24 is sandwiched between the divided blades 20 (b). In the case of this earth kneader 10, the earth for pottery can be pushed back and kneaded in two places. In this case, since the length of the kneading jig 18 is longer than that in the case of FIG. 1, the kneading effect due to the introduction of the earthenware for one time can be enhanced.

  Moreover, in the kneader 10, as shown in FIG. 6, the kneading jig 38 includes first blades 40 (a) and 40 (b) that are flat rather than screws, and a second blade 42. May be. Even with such a kneading jig 38, the earthenware can be pushed back and kneaded by the blade 42. The earthenware can also be kneaded by the action of cutting the earthenware soil with the blade 40.

  Moreover, in the kneader 10, as shown in FIG. 7, the first blade 20 (a) is formed by combining the parts 26 (a), 26 (b), and 26 (c) so that the surfaces thereof are not continuous. May be. In order to improve the kneading efficiency, the parts 26 (a), 26 (b) and 26 (c) may be used in order to improve the kneading efficiency if the blade 20 (a) is exclusively kneaded, unlike the blade 20 (b) exclusively for discharging the clay. ) Of each other may be adjusted. That is, although the speed at which the earthenware is fed is somewhat slow, the earthenware can be kneaded while being cut by the joints of the parts 26 (a), 26 (b) and 26 (c).

  Further, the second blade of the kneader 10 of the present invention may be the second blade 52 shown in FIG. The blade 52 has the same height H as that of the first blade 22 but includes a hollow portion 54. Therefore, the earthenware soil pushed back by the blade 52 can be sent from the hollow portion 54 toward the discharge port 14. Thereby, the effect substantially the same as the kneader shown in FIG. 1 etc. arises.

  As mentioned above, although the earth kneader and the kneading jig of this invention were demonstrated based on drawing, it is not limited to what was illustrated. For example, a vacuum kneader having a kneading jig including the first blade and the second blade as described above and kneading while ventilating the air in the kneading chamber may be used. Moreover, the earthenware for kneading | mixing with the kneader and kneading jig of this invention is not limited to two types, One type or three types or more may be sufficient. Moreover, the quality of the earth for pottery to knead | mix will not be specifically limited if it can be used for pottery. Moreover, the shape of the braid | blade of a kneading jig is not limited to the above-mentioned screw shape and flat plate shape, Other shapes may be sufficient. For example, a combination of rod-shaped members may be used. Further, the second blade does not have to be located between the first blades.

  Although the embodiment of the kneader of the present invention has been described above, the present invention can be carried out in various modified, modified, and modified embodiments based on the knowledge of those skilled in the art without departing from the spirit of the present invention. All of these aspects belong to the scope of the present invention.

  The clay kneader and the kneading jig of the present invention knead the clay for clay more quickly and reliably by sending the clay for earth to the discharge port by the first blade and returning to the reverse direction by the second blade. Therefore, it can be widely used for kneading various earthenware.
