Description

Double-barrelled aircraft nose assembly of cotton extruder of EPE pearl

Technical Field

The utility model relates to a cotton processing equipment of EPE pearl, in particular to double-barrelled aircraft nose assembly of cotton extruder of EPE pearl.

Background

When processing EPE pearl cotton, firstly, uniformly mixing raw materials such as polyethylene and the like, putting the raw materials into a hopper of an extruder, melting and mixing the raw materials by the extruder with a large length-diameter ratio, simultaneously injecting foaming gas and molten monoglyceride into the middle part of the extruder at high pressure, uniformly mixing the foaming gas and the molten monoglyceride with melted and mixed plastics, extruding and molding the mixture by a machine head and a die, and cooling, drawing, flattening and winding the mixture to obtain a foaming sheet (film) product. The die is a perforated member mounted at the end of the extruder which forms the extrudate into a prescribed cross-sectional shape. The die attachment is the portion between the die and the barrel and this combination is referred to as the head. The head generally includes a distribution chamber, a flow guide, and a die shaping section ("die lip").
