る。The basic structure of the pellet molding machine is that a spiral screw is arranged in a cylinder, a hopper for charging a molding raw material is provided at the base end of the cylinder, and a large number of molding holes are formed. An extruded plate through which is inserted is attached to the tip of the cylinder, and a molding raw material to which an appropriate amount of water has been added is charged into the cylinder from the hopper and transferred forward while kneading with the spiral screw. Then, the raw material kneaded by the extrusion pressure due to the rotation of the spiral screw is extruded into a pellet form from each forming hole of the extruded plate.

る。The conventional shape of the molding hole penetrating the extruded molding plate 51 has the same diameter over the entire length as shown in FIG. 9 or the inlet as shown in FIG. It was the mainstream that the part was formed in a tapered shape, and the diameter from the end of the tapered part to the outlet was the same. Since the former forming hole 52 has the same diameter over its entire length, all the parts thereof function as forming parts, and the latter forming hole 53 has only the part having the same diameter opened on the outlet side. It functions as a molding part, and the tapered portion on the inlet side only has a function of making it easier for the raw material to enter the molding part.

あった。As described above, the forming holes penetrating the conventional extruded plate are required because the end of the formed part is the end face on the outlet side of the extruded plate. There is a drawback that the extrusion pressure becomes large (that is, the horsepower required as a pellet molding machine becomes large and the capacity of the motor becomes large). In this way, when the extrusion pressure of the raw material increases,
The plate thickness (T ') of the extruded plate also had to be increased accordingly.
