Abstract

The invention discloses an efficient multifunctional double-screw extruder unit which comprises a weight-loss continuously-weighing metering feeder, a steel frame platform, a co-rotating parallel double-screw mixing extruder, a double-plunger hydraulic pressure screen changer, a high-temperature melt pump and a hydraulic pressure flow dividing valve. The weight-loss continuously-weighing metering feeder is used for continuous matching of components of polymers, the co-rotating parallel double-screw mixing extruder is used for mixing modification of the components of the polymers, the double-plunger hydraulic pressure screen changer is used for filtering impurities in the polymers, the high-temperature melt pump can simultaneously perform modification, forming and extrusion of the polymers, the hydraulic pressure flow dividing valve is used for switching melt runners when the efficient multifunctional double-screw extruder unit works and stops, automatic operation of the extruder unit is facilitated, and extrusion forming effects of melts are ensured. According to the extruder unit, blending modification and forming extrusion of the polymers can be finished, and the extruder unit solves the problems of high production cost and low efficiency in the machining production process of a traditional two-step method.

Description

technical field [0001] The invention relates to the field of high molecular polymer material processing equipment, in particular to a high-efficiency multifunctional twin-screw extruder unit. Background technique [0002] As an important technology in the polymer processing industry, the blending modification and extrusion molding technology of polymer materials grows along with the development of polymer processing industry technology. The total volume of high molecular polymer materials in the world has exceeded that of metal materials. High molecular polymers can only become valuable products through blending modification and extrusion molding. Blending modification and extrusion of high molecular polymer materials Molding is an indispensable production link of polymer materials. [0003] In the traditional typical blending modification and extrusion molding production process, a two-step process is used for processing operations. First, the polymer components are homog...
