FIG. 1 is a schematic view of an extrusion device of a screw extruder according to the present invention;

FIG. 2 is a schematic structural diagram of a filter plate according to the present invention;

fig. 3 is a schematic structural diagram of the middle extrusion plate of the present invention.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

The utility model provides a pair of screw extruder's extrusion device, on current screw extruder's basis, install this extruder's extrusion device on the tail end of extruder, because current is direct to fix the filter screen in the aircraft nose, the extruder leans on at the during operation that the screw rod is rotatory to be sheared the material, and the material is rotated the back rotation wrinkle easily also with the filter screen when rotating forward transport, even tears, leads to extruding failure, combines the utility model discloses an extrusion device has avoided this kind not enough, and specific structure is following.
