が生じ易くなる。In this conventional apparatus, the supply amount is determined by each hopper, and a constant amount is constantly dropped into the mixing hopper while considering the difference between the two ratios. Since it is far from the mouth, if the difference in the mixing ratio becomes large in the mixing by natural fall, it is difficult to mix the molding material with a small mixing amount evenly, and the mixing ratio is often unstable, which is why Good products are likely to occur.

きるようにしたことから、下記効果を奏する。As described above, according to the present invention, the material hopper 7 is composed of the outer hopper 8 and the small inner hopper 9 housed in the outer hopper 8, and the lower opening of the outer hopper 8 is used as a plasticizer for the screw interior. While being connected to the supply port 5, the supply pipe 11 is provided near the screw from the lower opening 10 of the inner hopper 9.
Is configured to be movable up and down, and the supply space L between the lower end of the supply pipe 11 and the screw can be arbitrarily adjusted, so that the molding material in the inner hopper can be measured and the supply amount can be adjusted. Therefore, the following effects are achieved.

ができるので、混合比率が不適当な不良品の発生が防止
される。Since the molding material of the inner hopper is weighed near the screw and supplied together with the molding material of the outer hopper, the mixing ratio is always set as set, and both mixing ratios are not affected. Since the molding material can be supplied evenly, it is possible to prevent the generation of defective products having an inappropriate mixing ratio.

成形することもできる。Since the supply amount of the outer hopper does not change even if the supply pipe is moved up and down, the adjustment needs to be performed only on the inner hopper side, and since the adjustment is performed by the movement amount of the supply pipe, the accuracy is high. Also, in the case of mixing colored resins, the color tone can be freely selected by adjusting the mixing ratio, and a molded product having a delicate color tone can be molded.

有する。With regard to the structure of the device, it is only necessary to combine the hopper and provide the inner hopper with a supply pipe of a required length so as to be movable up and down, and since the operation of the supply pipe can be easily performed by using a cam or the like, it is highly advanced. It has advantages such as not requiring the technology of.
