Composite straw molding machine

A composite straw molding machine, comprising: a platen roller serrations (1), forming the pressing roller (2), a sawtooth platen (3), a cross web (4), a power shaft (6), the extrusion die ( 7), characterized in that: while setting extrusion assembly and cutting assembly preload: vertically disposed power shaft (6) at the center of the extrusion die (7), the horizontal cross webs provided on the power shaft (6) (4), symmetrically arranged forming two press rolls (2), and two sawtooth platen roller (1) in the cross-shaped connection plate (4); at the upper horizontal extrusion die (7) is provided serration platen (3) , power shaft (6) drives a cross-shaped plate (4), forming the pressing roller (2), a sawtooth platen roller (1) rotates. Its advantages are: the first material through the serrations shear and serrated roller platen press, rolling, increases the adaptability of the raw material, reducing reactive power losses, reduces wear molded parts, improved molding results.
