Co-rotating differential asymmetric twin-screw extruder capable of achieving continuous extruding and machining method thereof

Abstract

The invention discloses a co-rotating differential asymmetric twin-screw extruder capable of achieving continuous extruding and a machining method thereof. The extruder comprises an equipment shell, and the top and the bottom of an inner cavity of the equipment shell are movably connected with a first rotating screw and a second rotating screw through bearings correspondingly; and the surfaces ofthe first rotating screw and the second rotating screw are fixedly connected with stirring cams which are arranged in a crossed manner. According to the co-rotating differential asymmetric twin-screwextruder, through the equipment shell, the stirring cams, a hot melting cavity, driving frames, the first rotating screw, an extrusion head, a driven gear, a speed regulating motor, a rotating rod, adriving gear and the second rotating screw, the device can achieve the function of a good using effect, and the problems that screw extruders on the existing market do not have the function of the good using effect, during mixed injection molding operation for multiple kinds of color masterbatch, the phenomenon that the color masterbatch mixing effect is poor, the color difference of extruded materials is large, and therefore, the product quality is influenced often occurs, and a user cannot use the screw extruders conveniently are solved.

Description

technical field [0001] The invention relates to the technical field of screw extruders, in particular to a co-direction differential speed asymmetric twin-screw extruder capable of continuous extrusion and a processing method thereof. Background technique [0002] The screw extruder relies on the pressure and shear force generated by the rotation of the screw, which can make the material fully plasticized and evenly mixed. Through the die molding, the plastic extruder can be basically classified into twin-screw extruder, single-screw extruder, etc. Extruder and rare multi-screw extruder and screwless extruder. [0003] In the injection molding industry, it is necessary to use screw extruders for injection molding. The screw extruders on the existing market do not have the function of good use effect. In the mixed injection molding operation for multiple color masterbatches, the mixing of color masterbatches often occurs. If the effect is not good, the color difference of th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a co-rotating differential speed asymmetric twin-screw extruder capable of continuous extrusion and its processing method. In the mixed injection molding operation for multiple color masterbatches, the mixing effect of the color masterbatch often appears poor, resulting in a large color difference in the extruded material, which affects the quality of the product, which is not conducive to the user's operation and use.
