Description
【０００１】[0001]
本考案は、スクリュ軸機械に係り、ゴム、プラスチック、食品等の混練、押出 等に利用される。 INDUSTRIAL APPLICABILITY The present invention relates to a screw shaft machine and is used for kneading and extruding rubber, plastic, food and the like.
【０００２】[0002]
ゴム、プラスチック等の混練用２軸押出機 (スクリュ軸機械) として、図６に 示すものがある。 このスクリュ軸機械1 は、管状バレル2 にスクリュ3 をこの軸心回りに回転自 在として挿入しており、その際、管状バレル2 の端部に設けたフランジ4 の下面 にサポート5 の上部をボルト6 で固定し、サポート5 の下部は架台7 上に左右一 対のスライドガイド8 によって、バレル2 を加熱・昇温する際に生じる熱膨張に 対して前後方向 (バレル軸心方向) に摺動するようにしていた。 FIG. 6 shows a twin-screw extruder (screw shaft machine) for kneading rubber, plastics and the like. In this screw shaft machine 1, a screw 3 is inserted into a tubular barrel 2 around the axis of the screw 3 as a rotational rotation, while the upper part of a support 5 is placed on the lower surface of a flange 4 provided at the end of the tubular barrel 2. It is fixed with bolts 6, and the lower part of the support 5 is slid in the front-rear direction (barrel axis direction) against the thermal expansion that occurs when the barrel 2 is heated and heated by the pair of left and right slide guides 8 on the base 7. I was trying to move.
【０００３】[0003]
バレル2 を加熱・昇温する際には、前後方向に熱膨張するだけでなく上下方向 にも熱膨張する。このとき、バレル2 をサポート5 で下部にて支持しているため 、バレル熱膨張における下方への膨張が拘束されることとなり、上方にだけ伸び ようとするため、バレル内径面2Aが上方向にズレを生じ、バレル2 内に挿入した スクリュ3 はギヤボックスにて固定されたままであるため、バレル軸心とスクリ ュ軸心とが芯ズレして内径面2Aと干渉するおそれがあった。 When the barrel 2 is heated and heated, it not only thermally expands in the front-back direction but also vertically. At this time, since the barrel 2 is supported by the lower portion by the support 5, the downward expansion due to the thermal expansion of the barrel is restrained, and the expansion of the barrel is attempted only upward. Since the screw 3 inserted into the barrel 2 is still fixed by the gear box, the barrel axis and the screw axis may be misaligned and interfere with the inner diameter surface 2A.
【０００４】 そこで本考案は、管状バレルが熱膨張するとき、バレルの下方への熱膨張を保 証してバレルとスクリュを調心するようにしたことを目的とする。Therefore, an object of the present invention is to, when the tubular barrel thermally expands, ensure the thermal expansion downward of the barrel and align the barrel and the screw.
【０００５】[0005]
本考案は、下部をサポート16で支持した細長い管状バレル12に、スクリュ14を この軸心回りに回転自在として挿入しているスクリュ軸機械において、前述の目 的を達成するために次の技術的手段を講じている。 すなわち、本考案は、前記管状バレル12の熱膨張時に、バレル軸心とスクリュ 軸心とを調心する手段18を前記サポート16に備えているものである。 The present invention relates to a screw shaft machine in which a screw 14 is rotatably inserted around this shaft center in an elongated tubular barrel 12 whose lower part is supported by a support 16 in order to achieve the above-mentioned object. I am taking steps. That is, in the present invention, the support 16 is provided with means 18 for aligning the barrel axis and the screw axis when the tubular barrel 12 is thermally expanded.
【０００６】[0006]
管状バレル2 が熱膨張するとき、前後方向だけでなく前後の膨張に対して比例 的に下方向にも揺動してバレル軸心とスクリュ軸心を、関接部18A,18B 等による 調心手段18で調心する。 When the tubular barrel 2 thermally expands, it swings not only in the longitudinal direction but also in the downward direction in proportion to the expansion in the longitudinal direction, so that the barrel axis and the screw axis are aligned by the joints 18A, 18B, etc. Align with means 18.
【０００７】[0007]
以下、図を参照して本考案の実施例を説明する。 図１実施例を示した図１および図２において、スクリュ軸機械10は、２軸押出 機として例示してあり、眼鏡形チャンバ11を有する細長い管状バレル12と、該バ レル12のチャンバ11に挿入されていてギヤボックス13に支持されている軸心回り に回転自在なスクリュ14とからなる。 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 showing an embodiment, the screw shaft machine 10 is illustrated as a twin-screw extruder, and includes an elongated tubular barrel 12 having a spectacle-shaped chamber 11 and a chamber 11 of the barrel 12. The screw 14 is inserted and supported by the gear box 13 and is rotatable about an axis.
【０００８】 バレル12はこの軸方向に複数個に区分されていて端部のフランジ15をボルト接 合している。 更に、バレル12はこの下部を、サポート16を介して架台17に支持しており、該 サポート16の上下には関接部18A,18B を有し、該関接部が調心手段18とされてい る。The barrel 12 is divided into a plurality of parts in the axial direction, and the flanges 15 at the ends are bolted together. Further, the lower portion of the barrel 12 is supported by the pedestal 17 via the support 16, and the joints 18A and 18B are provided above and below the support 16, and the joints serve as the aligning means 18. ing.
【０００９】 すなわち、バレル12が熱膨張した場合、前方向にバレルが伸びるためサポート 16が前方向に傾斜し、前方向の熱膨張を吸する。更に、上下方向の熱膨張に対し ては、サポート16が前方向傾斜するためバレル12が下方向に揺動し、ここに、上 下方向の熱膨張を吸収することによってチャンバ11をスクリュ14との干渉を防止 している。That is, when the barrel 12 thermally expands, the barrel 16 extends in the front direction, so that the support 16 tilts in the front direction and absorbs the thermal expansion in the front direction. Further, with respect to the thermal expansion in the vertical direction, the barrel 16 swings downward because the support 16 inclines forward, and the chamber 11 becomes the screw 14 by absorbing the thermal expansion in the upward and downward directions. To prevent interference.
【００１０】 図３は第２実施例であり、調心手段18がスライドテーパ18C とされており、そ の他は、既述の第１実施例と共通する。 図４は第３実施例であり、調心手段18を有するサポート16がバレルの長手方向 に間隔をおいて複数個具備されたもので、その他は、既述の第１実施例と共通す る。FIG. 3 shows a second embodiment, in which the aligning means 18 is a slide taper 18C, and other points are common to the above-described first embodiment. FIG. 4 shows a third embodiment, in which a plurality of supports 16 each having an aligning means 18 are provided at intervals in the longitudinal direction of the barrel. Others are common to the first embodiment described above. .
【００１１】 図５は第４実施例であり、一軸形にした例であり、その他は第１実施例と共通 する。 なお、本考案は、ゴム、プラスチック、食品等の混練、成形等に利用されるも のである。FIG. 5 shows a fourth embodiment, which is a uniaxial type, and the others are common to the first embodiment. The present invention can be used for kneading, molding, etc. of rubber, plastic, food and the like.
【００１２】[0012]
本考案は、以上の通りであり、管状バレルが熱膨張しても該バレル軸心とスク リュ軸心は調心されて両者の干渉を防止できる。 The present invention is as described above, and even if the tubular barrel is thermally expanded, the barrel axis and the screw axis are aligned and the interference between the two can be prevented.
