(57) [Summary] [Objective] An object of the present invention is to provide an extruder capable of forming a molded product having an averaged packing density. [Composition] In a screw extruder for extruding a press-fitted molded body by rotating a screw, after the screw, before the mouthpiece, there is a portion protruding from the wall of the extruder so that the extrusion molding material is once squeezed. The extrusion molding machine is characterized by performing extrusion molding by passing through a portion having a reduced diameter.
Description
【０００１】[0001]
本考案は、充填密度が平均化される押出成形機に関する。 The present invention relates to an extruder in which the packing density is averaged.
【０００２】[0002]
従来の押出成形機は、粘土等の粘性の高い物質を押出成形するには、スクリュ ウで押出す押出成形機を用いることが多いが、圧入押出された物質は、その充填 密度が十分でない部分が生じがちで、充填密度が十分でない部分で、損壊が生じ 易く、また、その成形体を焼成した場合にも、クラック、破損が生じ易くなる。 Conventional extruders often use extruders that use a screw to extrude highly viscous materials such as clay. Is likely to occur, and damage is likely to occur at a portion where the packing density is not sufficient, and cracking and damage are likely to occur even when the molded body is fired.
【０００３】[0003]
本考案は、上記の問題点を解決するためになされたもので、充填密度が平均化 された成形体ができる押出成形機を提供することを目的とする。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an extruder capable of forming a molded body having an averaged packing density.
【０００４】[0004]
本考案は、上記の技術的な課題の解決のためになされたもので、圧入成形体を スクリュウ回転で押し出すスクリュウ押出成形機において、 該スクリュウの後、口金の前に、押出成形材料を一旦しぼるように、押出成形 機の壁から突出させた部分を有し、口径を小さくした部分を通過させて、押出成 形することを特徴とする押出成形機を提供する。 The present invention has been made in order to solve the above technical problems, and in a screw extruder for extruding a press-fitting molded body by screw rotation, the extrusion molding material is once squeezed after the screw and before the mouthpiece. Thus, there is provided an extrusion molding machine characterized by having a portion protruding from the wall of the extrusion molding machine, and passing through a portion having a reduced diameter to perform extrusion molding.
【０００５】[0005]
本考案による押出成形機では、圧入成形体はスクリュウ回転で押し出されてい くが、スクリュウのすぐ後に、突出された部分があり、圧入押出成形材料が通過 する部分は、急に狭くなっているものである。そのために、押出成形材料は一旦 絞られていき、充填密度が非常に高いものとなり、均一なものとなる。その後に 、押出成形材料は、押出成形されるのであるから、押出成形のための充填密度は 、均一化されて、押出成形体は、従来のような欠損等が、生じ難いものとなる。 In the extrusion molding machine according to the present invention, the press-fitting molded body is extruded by the screw rotation, but there is a protruding part immediately after the screw, and the part through which the press-fitting extrusion molding material passes is suddenly narrowed. Is. Therefore, the extrusion molding material is once squeezed, and the packing density becomes very high, and the material becomes uniform. After that, since the extrusion molding material is extruded, the packing density for extrusion molding is made uniform, and the extruded body is unlikely to suffer from defects such as the conventional ones.
【０００６】 従って、本考案の押出成形機では、非常に充填度が均一である押出成形体が得 られることとなる。Therefore, the extrusion-molding machine of the present invention can provide an extrusion-molded body having a very uniform filling degree.
【０００７】 次に、本考案の押出成形機について、具体的に実施例により説明するが、本考 案はそれらによって限定されるものではない。Next, the extruder of the present invention will be specifically described by way of examples, but the present invention is not limited thereto.
【０００８】[0008]
図１は、本考案の押出成形機１の横断面を示す断面図であり、その主要部を明 らかにするものである。 圧入押出される原料３は、スクリュウ２の回転により、図に示す矢印のように 、圧入され、右への進んでいき、本考案による突起部４により、圧力を受けて、 密度高く、充填され、平均化される。更に、押出されて、口金７に入っていく。 FIG. 1 is a cross-sectional view showing a cross section of an extrusion molding machine 1 of the present invention, in which a main part is clarified. The raw material 3 to be press-fitted and extruded is press-fitted by the rotation of the screw 2 as shown by the arrow in the figure, and proceeds to the right. , Averaged. Further, it is extruded and enters the mouthpiece 7.
【０００９】[0009]
以上説明したように、本考案の押出成形機では、次にのような顕著な技術的効 果が得られた。 即ち、押出圧入される充填密度が平均化された押出成形機が得られる。 As described above, the extrusion molding machine of the present invention has the following remarkable technical effects. That is, an extrusion molding machine in which the packing densities to be press-fitted are averaged can be obtained.
