【発明の詳細な説明】
本発明は押出機に対し主原料と同時に添加剤を
供給するときの供給方法および装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding method and apparatus for feeding additives to an extruder simultaneously with main raw materials.

点が低い場合は次のような問題が発生し生産に支
障をきたしていた。 During kneading and extrusion in an extruder, main raw materials and additives such as modifiers or fillers are often fed simultaneously via a feeder. Among these additives, when the melting point is low, the following problems occur and production is hindered.
(1) フイード口周辺の温度影響を受けて添加剤が
溶融してフイード口周辺に付着し主原料と共に
安定した連続供給が不可能になる。(1) Under the influence of the temperature around the feed opening, additives melt and adhere to the area around the feed opening, making it impossible to provide stable and continuous supply along with the main raw material.
(2) 溶融付着した添加剤が時間の経過と共に変質
して間欠的にフイード口へ落下して製品に悪影
響を与えていた。(2) The melted additives deteriorated over time and intermittently fell into the feed port, adversely affecting the product.
(3) 押出機圧縮部からの加熱気体の戻りにより添
加剤が溶融してフイード口へ付着した。この結
果連続供給が不可能になつたり混合比率が変化
した。(3) The additive melted and adhered to the feed port due to the return of heated gas from the extruder compression section. As a result, continuous supply became impossible or the mixing ratio changed.

シユートの形状や投入位置に対し多くの提案がさ
れているが前記欠点を完全に解消したものはなか
つた。 Even if the additive is inorganic and has a high melting point, the additive may stagnate due to the build-up and adhesion of the main raw material at the feed port, or may absorb moisture due to the influence of heated gas from the compression section, causing the feed port wall surface to deteriorate. It was impossible to provide a stable continuous supply such as adhesion to the surface. For this reason, many proposals have been made regarding the shape and loading position of the chute, but none have completely solved the above-mentioned drawbacks.
本発明はかかる観点からなされたものでその目

供給方法および装置を提供することにある。 The present invention was made from this point of view, and its purpose is to provide an extruder that is not affected by feed port wall temperature, heated steam from the compression section, etc. when main raw materials and additives are supplied simultaneously. An object of the present invention is to provide a method and device for supplying a drug.

号１０はスクリユである。 The present invention will be explained below with reference to figures showing one embodiment. First, the case where the main raw material is melt feed will be explained. The main raw material (not shown) flows through the pipe line 1 from the wall hole 3 of the box-like body 2 into the main raw material passage 4, which is an inner hole of the box-like body 2, where it becomes a box-like body and passes through the feed port. 5 into the extruder cylinder 6. On the other hand, an additive (not shown) is introduced into a chute 7 provided at the center of the box-like body 2 from a feeder (not shown) and is fed into the extruder cylinder 6 from the feed port 5. The chute 7 has a funnel shape, and a partition A8 is provided on the outer periphery of the cylindrical portion, and the chute 7 is cooled by passing water between the inside of the partition A8 and the outside of the cylindrical portion. Moreover, a partition B9 is provided with an air layer placed outside the partition A, and this air layer may be stationary or flowing. Note that the reference numeral 10 is a screw.

る。 Next, the operation of the present invention will be explained. The melted and high-temperature main raw material is fed from a pipe line 1 through a main raw material passage 4 of a box-shaped body 2 into a cylindrical shape through a feed port 5 into an extruder cylinder 6. On the other hand, the additive is supplied in the form of a cylinder from the chute 7 through the feed port 5 into the extruder cylinder 6, and is surrounded by the main raw material. Since water passes through the partition A8 in the cylindrical portion of the chute 7 that is in contact with the main raw material, the cylindrical portion is cooled, and the additive is not affected by heat from the cylindrical portion. Further, since the outer periphery of the partition A8 is covered by the partition B9 having an air layer, the melted main material flows down the main material passage 4 while maintaining its temperature without being cooled. However, the amount of the melted main raw material should be such that it does not swell to the point that it comes into contact with the A side.
前記説明では主原料はメルトされた場合につい
て述べたが粉体状のときは、常温であつて添加物
を加熱することはないので仕切Ａ８および仕切Ｂ
９は不要であるが、主原料通路４の通路断面積は
大きくすることが好ましい。 In the above explanation, the case where the main raw material is melted is described, but when it is in powder form, it is at room temperature and the additives are not heated, so partition A8 and partition B are used.
9 is not necessary, but it is preferable that the cross-sectional area of the main raw material passage 4 be large.

するように構成した。 As described above, the extruder additive supply method and device of the present invention supplies additives in a cylindrical manner from a funnel-shaped chute to the feed port of an extruder cylinder, and covers the main raw material in the cylindrical portion of the chute. The material is fed from the side of the box to form a cylindrical shape inside the box, and the cylindrical main raw material is supplied to the feed port so as to enclose the additive.
このため次のような利点を有する。 Therefore, it has the following advantages.
(1) 添加剤は押出機シリンダのフイード口におけ
る盛上りの影響を受けることがなくなつた。(1) Additives are no longer affected by build-up at the feed port of the extruder cylinder.
(2) 押出機シリンダ圧縮部から戻る加熱気体の影
響を受けなくなつた。(2) It is no longer affected by the heated gas returning from the extruder cylinder compression section.
(3) 添加剤は低融点でも主原料からの熱影響を受

(4) メルトされた主原料であつても添加剤の熱影
響を受けなくなつた。(4) Even if the main raw material is melted, it is no longer affected by the heat of additives.
(5) 主原料および添加剤の混合比を一定に保ちな
がら安定した連続供給が可能になつた。(5) Stable continuous supply is now possible while keeping the mixing ratio of main raw materials and additives constant.
