Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は、熱可塑性樹脂の溶融混練押出機の添加剤供給
口に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an additive supply port for a melt-kneading extruder for thermoplastic resin.

（従来の技術） 熱可塑性樹脂の溶融混練押出機には、溶融成形される樹
脂の物性向上のため、各種の添加剤が投入されている。(Prior Art) Various additives are added to a melt-kneading extruder for thermoplastic resin in order to improve the physical properties of the resin to be melt-molded.

一般に、融点の低い添加剤あ、るいは熱履歴を加えすぎ

壁面に付着し湿気を帯びている。In the case of polymer blends, to enhance the mixing effect,
Since the main raw materials are once kneaded and melted, and the auxiliary raw materials are mixed therein, they are often supplied through this second supply port. Since this second supply port is directly attached to the extruder cylinder and located in the middle of the extruder, its wall surface temperature is high during molding, and moisture and volatile matter from the molten resin adhere to the wall surface, making it humid. ing.

安定した供給が得られないという欠点があった。(Problems to be Solved by the Invention) Conventionally, when the above-mentioned low melting point or heat-sensitive additives or auxiliary raw materials were supplied from the second supply port, the wall surface was high temperature and high humidity, There was a drawback that the material adhered to the wall surface and stable supply could not be obtained.

ス吸引口を設けた押出機添加剤供給口である。In order to solve the problem caused by high temperatures, a supply nozzle is provided, a water cooling jacket is arranged on the outer circumferential surface of the supply nozzle, and a gas suction port is provided to remove moisture and volatile matter. It has a frame body that covers the opening of the extruder cylinder and a lid plate of the frame body, a supply nozzle that penetrates the lid plate and reaches into the cylinder, and a water cooling jacket is arranged on the outer peripheral surface of the nozzle, The extruder additive supply port is provided with a gas suction port in the frame or the lid plate.

Further, moisture and volatile substances remaining in the cylinder opening are exhausted to the outside through the gas suction port.

にある。A cylindrical frame 6 and a cover plate 7 are installed to cover the opening of the extruder cylinder 1, and are reinforced with a plate 8. The supply nozzle 3 passes through the cover plate 7 and the reinforcing plate 8.
A water cooling jacket 4 is provided on the outer peripheral surface of the cylinder 1 on the inside side of the cover plate 7. Further, the tip of the supply nozzle 3 is located at a position that allows an appropriate distance from the slot 1-2.

Furthermore, the water supply pipe 9 and the drain pipe 10 pass through the frame 6 (note that the part through which the drain pipe 10 passes through the frame 6 is omitted in the illustration). A port 5 is provided to remove moisture and volatile substances that remain at the cylinder opening.
The air is exhausted from here through the exhaust pipe 11 to the outside.
