た。 Therefore, recently, various types of high-quality ceramic products are manufactured at low cost by using cheap raw materials, raw materials with high plasticity as the main raw materials, and coating the surface with high-quality raw materials, raw materials with low plasticity, etc. , JP-A No. 1983-1997 is the first example of a method for coating dissimilar raw materials.
Although there is a device for extruding ceramic materials coated with different raw materials as described in Publication No. 179606,
In such a device, the tip of a screw-type extruder for extruding the coating material is vertically connected to the can cylinder at the tip of the extruder for the base material, and both extruders are operated to release the extruder for the base material. Since the coating raw material is compressed during the compression molding process of the base raw material, the pressure and pressure associated with compression molding occur before the polymerized raw material is discharged from the discharge port. The base raw material and the coating raw material are mixed due to the twist caused by the screw pressing, and for this reason, it is difficult to coat only the surface layer of the base raw material with the coating raw material, and the coating raw material is extruded from the perpendicular direction to the base raw material. Therefore, the coating thickness is directly affected by the extrusion pressure of the coating raw material, and the extrusion pressure of the screw extruder is difficult to adjust, so it has the disadvantage that it is impossible to make the coating thickness uniform. .

果甚だ大なるものである。 In short, the present invention provides an extrusion molding machine 1 for main raw material A.
The main raw material A is extruded from the main raw material A, and an auxiliary material 21 such as slurry, glaze, sand, white ground powder, etc. is attached to the surface of the main raw material A, and coating material B is applied to any surface of the extruded main raw material A. The coating raw material B extruded from the extrusion molding machine 7 is polymerized by obliquely interfering with the discharge trajectory of the main raw material A, and the polymerized main raw material A and the coating raw material B are pressed together by a roller 17,
17a, so even if the extrusion molding machine 7 is a screw type, in which it is difficult to adjust the extrusion pressure, the main raw material It becomes easy to coat A with the coating raw material B always with a uniform thickness, and even if the coating raw material B is a raw material with particularly low adhesiveness, it will adhere to the surface of the main raw material A from the injection device 20 before polymerization. Because the auxiliary material 21 such as slurry, glaze, sand, white ground powder, etc. is attached to enhance the properties, the main raw material A and the coating raw material B can be reliably pressed together, and the main raw material A can be polymerized. By pressing the coating material B and the coating material B with the pressure rollers 17, 17a, it is possible to comprehensively improve the clamping and integration with constant uniform pressure, and the coating thickness of the coating material B can also be controlled by the extrusion molding machine. Its practical effects are enormous, such as being able to accurately and easily adjust the thickness to any desired thickness by simply replacing the nozzle 12 and guide member 13 of No. 7.
