the utility model provides a film extruder is with two filter screen bases, includes the base, one side of base is equipped with first ring groove, and the joint has first cartridge filter in the first ring groove, and the outer wall of first cartridge filter is equipped with a plurality of first filtration pores of crossing, one side fixedly connected with second cartridge filter of base, second cartridge filter cover are in the outside of first cartridge filter, and the outer wall of second cartridge filter is equipped with a plurality of second filtration pores of crossing, the one end of second cartridge filter is equipped with the end cap, and one side of end cap is equipped with second ring groove, second ring groove and first cartridge filter joint.

Furthermore, one side of the plug is provided with a plurality of butt-joint holes.

Furthermore, one end of the second filter cylinder is provided with a plurality of threaded holes.

Furthermore, one side of the base is provided with a plurality of first mounting holes.

Furthermore, one side of the base is provided with two second mounting holes.

Furthermore, the aperture of the second filtering hole is 50-100 meshes.

Furthermore, the aperture of the first filtering hole is 150-200 meshes.

The utility model has the advantages that:

1. the raw materials can be well filtered through the arrangement of filtering the raw materials by the first filter cartridge and the second filter cartridge, so that the filtering effect is improved, and the phenomenon that crystal points and fibers are remained on the membrane surface and flow marks appear on the surface of a product is avoided.

2. The apertures of the first filtering holes and the second filtering holes are different, so that the flow direction of the material is changed when the raw material enters the second filtering holes from the first filtering holes, and the filtering area and the turbulent flow are increased to enable the material to achieve a static stirring effect.
