Abstract

The invention discloses a different-diameter screw cold feed vented extruder, comprising an extrusion screw comprising multi-step different-diameter screws, and an extrusion cylinder, a venting cylinder, a plasticizing cylinder, a feeding base and a thin through ring which are matched with the different-diameter screws, wherein for realizing the balance of production capacity, the screw thread external diameter of a working segment of the extrusion screw is different in steps, the extrusion screw can be an integral structure or a separate structure, the steps are threadedly connected with each other, a positioning segment for guaranteeing the concentricity of external diameters of two adjacent screws is designed, the combination of axial seal and end face seal is adopted for guaranteeing the sealing; screw heads are threadedly connected with a screw body at the metering section, and the screw body at the metering section is provided with a larger water channel. According to the invention, the different-diameter extrusion screw is adopted, the maximum production capacity of the first step cold feed screw using forced cold feed is released handily, the production efficiency of the cold feed vented extruder can be greatly raised, and the unit energy consumption can be reduced.

Description

(1) Technical field: [0001] The invention relates to a rubber cold feed exhaust extruder, in particular to a different-diameter screw cold feed exhaust extruder. (2) Background technology: [0002] Cold feed exhaust extruder is a kind of equipment commonly used in rubber processing. It adopts normal pressure vulcanization and moldless vulcanization rubber products such as rubber sealing strips, electric wires, inner tubes and some cables, rubber hoses, etc. Gas extruder for continuous production. With the development of tire processing technology and the application of pre-vulcanization technology for tire components, some tire components also show the need for exhaust extrusion technology. [0003] The cold-feed exhaust extruder mostly adopts second-stage equal-diameter screws, which are composed of two ordinary screws connected in series. The first-stage is an ordinary cold-feed screw. , the rubber material is plasticized and heated, and then enters the second stage thro...
