Abstract

The invention belongs to the technical field of rubber extruders, and relates to a rubber exhaust extruder. A main body structure comprises an extruder cylinder, a gear pump, a speed reducer and a mold temperature control box, wherein one end of the extruder cylinder is connected to the gear pump, the other end of the extruder cylinder is connected to the speed reducer, the extruder cylinder is electrically connected to the mold temperature control box, the gear pump is connected to a gear pump motor, the speed reducer is connected to an electromotor, the extruder barrel is provided with a feeding port and an exhaust port, the extruder barrel, the gear pump, the gear pump motor and the speed reducer are all arranged on the base of a frame type structure. The working efficiency of the exhaust extruder is improved through the additional gear pump, a cooling system is arranged in the gear pump, heat generated by a rubber material is exchanged and released through heat exchange, a herringbone tooth gear has larger extrusion force in the working process and has larger friction force on the rubber material, the exhaust port can prevent the situations of material overflowing and material hanging on the inner wall of the machine barrel in the working process of the extruder main body, and meanwhile gas released by the rubber material can be conveniently exhausted.

Description

Technical field: [0001] The invention belongs to the technical field of rubber extruders, and relates to a rubber exhaust extruder, which can improve work efficiency and exhaust effect. Background technique: [0002] The rubber exhaust extruder is a kind of extruder equipment, which can effectively discharge the water vapor, air and volatile gas in the rubber, control the gas content in the rubber material, ensure the quality of the product, and prevent the quality of the rubber material. affected so that the raw material does not have to be dried. It is generally used to discharge the mixed gas in the rubber compound, and at the same time, it can also play a role in uniform mixing. Its development has gone through plunger extruder, screw type hot feed extruder, common cold feed extruder, main and auxiliary thread cold feed extruder, cold feed exhaust extruder, pin cold feed Material extruder and composite extruder and other stages. [0003] The cold-feed exhaust extruder...
