Abstract

The invention relates to rotor flashboard type rubber continuous banburying extrusion method and device. A rubber material is plastified and mixed by rolling and grinding an eccentric rotor on the inner wall surface of a stator cylinder, a flashboard restricted by the stator and floating along with the rotor blocks the flowing of the rubber material along the peripheral direction of the rotor in a gap between the rotor and the stator and drives the rubber material to flow along the axis direction of the rotor, and the continuous banburying extrusion of the rubber material is realized. A flashboard type banburying unit comprises the stator with a cylindrical cavity, the eccentric rotor arranged in the cavity of the stator, the flashboard arranged in the radius direction of the stator and restricted by the stator and material barrier discs arranged on both sides of the rotor. A plurality of flashboard type banburying units can be combined to form a rubber continuous banburying extrusionmachine. The invention has the characteristics of short heating mechanical action range of the rubber material, good mixing effect and little fluctuation, low equipment operating power consumption, small size and the like.

Description

technical field [0001] The invention relates to a rubber mixing processing method and equipment, in particular to a rotor gate type rubber continuous mixing extrusion method and equipment. technical background [0002] With the continuous development of the subject of polymer materials, rubber products have been widely used in many aspects. The rubber materials used in the traditional rubber industry are mixed in batches. At present, the factories mainly use internal mixers for mixing. The internal mixer is an important achievement of rubber mixing machinery, and it is still a typical equipment in plasticizing and mixing. According to foreign statistics, 88% of the rubber in the rubber industry is made by internal mixers. During the processing of the internal mixer, the rubber is mainly mixed by shearing and mixing between the rotors in the internal mixing chamber, between the rotor and the chamber wall, and between the rotor and the top bolt and the discharge door. The mi...
