Abstract

The invention discloses an integrated molding extruder for rubber extrusion, relates to rubber molding equipment, and provides the integrated molding extruder for rubber extrusion with the function of decreasing moisture contained in a rubber raw material in the extruder during conveying. The main point of the technical scheme is that the integrated molding extruder comprises a plurality of fixed barrels and air suction barrels which are coaxially arranged, wherein the inner diameter of the air suction barrels is smaller than the inner diameter of the fixed barrels; the air suction barrels and the fixed barrels are arranged at intervals; air suction holes are formed in the upper ends of the air suction barrels; exhaust check blocks which cover the air suction holes are arranged on the air suction holes of the air suction barrels; and vacuumizing devices used for sucking water vapor in the air suction barrels are arranged on the exhaust check blocks.

Description

technical field [0001] The invention relates to rubber molding equipment, in particular to an integrated molding extruder for rubber extrusion. Background technique [0002] A twin-screw kneading extruder is generally used for kneading and homogenizing a raw material composed of a rubber-based composition. [0003] The Chinese patent with the notification number CN1575960A discloses a quantitative supply device, which supplies raw materials to a mixing extruder that is forced to continuously extrude and discharge the raw materials after mixing, and is composed of the following parts: the raw materials are pulverized into coarse grains A pulverizer, an extruder that forcibly moves the raw material pulverized by the pulverizer to extrude, and a gear pump that introduces and outputs the raw material extruded by the extruder. However, the rubber raw material enters the extruder after being pulverized by the pulverizer, and there is a lot of water in the rubber raw material. If ...
