Embodiment Construction

[0029] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0030] figure 1 It is a conceptual cross-sectional view showing the rubber extruding device 1 of this embodiment. Such as figure 1 As shown, the rubber extrusion device 1 is used for kneading and extruding the unvulcanized rubber material G. The rubber extruding device 1 of the present embodiment includes: a closed kneader 2, which kneads the rubber material G; the extruded body Gb is kneaded and extruded; and the conveyor 4 that conveys the rubber material G to the kneader 2 .

[0031] As the kneader 2, it is preferable to use a Banbury mixer or an intermesh mixer that kneads the rubber material G in a substantially closed space. Such a kneader 2 can plasticize the rubber material G, prevent additives from splashing and uniformly disperse the additives in the rubber material G, and thus can improve the chemical reaction efficiency of the kneaded rubber Ga.

Abstract

The present invention provides a rubber extruding device and a rubber extruding method which can improve the quality of the rubber through mixing and extruding. The rubber extruding device (1) is configured to perform mixing and extruding of an unvulcanized rubber material, and comprises a mixer (2) for mixing the rubber material (G) in a closed space substantially; and an extruder (3) configuredto receive the rubber (Ga) obtained through mixing by the mixer (2), wherein the extruder (3) further comprises a screw rod (13) for mixing and extrusion. The extruder (3) is provided with a degassingportion (14) configured to absorb the gas in the extruder (3).

Description

technical field [0001] The present invention relates to a rubber extrusion device for kneading and extruding unvulcanized rubber material using a kneader and an extruder. Background technique [0002] As rubber extruders for kneading unvulcanized rubber materials, there are known kneaders for kneading in a substantially closed space and extruders for kneading and extruding with a screw shaft. Known kneaders include, for example, Banbury internal mixers, which are suitable for plasticizing rubber materials, preventing splashing of additives, and uniformly dispersing additives in rubber materials. The extruder is suitable, for example, for continuously extruding a rubber material into a predetermined cross-sectional shape. [0003] For example, Patent Document 1 below proposes a rubber extruder including a kneader and an extruder for receiving rubber kneaded by the kneader, kneading and extruding the rubber further. Such a rubber extruder uniformly kneads the unvulcanized ru...
