Abstract

The invention discloses a method and equipment for high polymer material slope pin roller size extensional rheology plasticization transportation. By means of a stator inner hole and rotor eccentricity, pin rollers are arranged in a plurality of slope grooves distributed uniformly in a rotor along the circumference, axes of the pin rollers are parallel with the axis of the rotor, surfaces of the pin rollers are tangent to the slopes of the slope grooves, the rotor rotates under resistance of materials and slope reaction thrust of the slope groves, the pin rollers roll in a planet mode and are tangent to the inner surface of a stator, and the materials in a space defined by the stator, the rotor and the pin rollers in an enclosing mode are politicized and transported under size extensional rheology due to the fact that the size of the materials change along with the periodical change of rotation of the rotor. An equipment structural unit for achieving the method is a slope pin roller plasticization transportation unit, and the slope pin roller plasticization transportation unit can be combined with various screw rod extrusion units or various plunger injection units to form a slope pin plasticization injection device of an extruder or an injector.

Description

technical field [0001] The invention relates to a polymer material plasticizing processing method and equipment, in particular to a polymer material slope roller volume extensional rheological plastic transportation method and equipment. technical background [0002] At present, the plasticizing processing of polymer materials mainly adopts the plasticizing transportation method based on shear deformation, and the equipment used is mainly screw machinery. The screw machine relies on the dragging effect on the material when the screw rotates during the plasticizing process, and the velocity gradient of the material is perpendicular to its flow deformation direction. This processing method usually has problems such as low output, high pressure fluctuations, large temperature fluctuations, and large output fluctuations, which directly lead to defects such as product size fluctuations, performance degradation, and narrow adaptability to materials. Through certain theoretical re...
