technical field
[0001] The invention relates to a plastic extruding and pressing film of renewable plastics and production equipment thereof. Background technique
[0002] At present, the plastic film extrusion laminating equipment commonly used in the market, its working process is to first add granular or powdery plastics into the hopper, and the granular or powdery plastics are released under the action of the rotating extruder screw. The powdery plastic is conveyed forward along the spiral groove of the screw. During this process, the granular or powdery plastic is continuously subjected to the external heating of the barrel, screw rotation, compaction, etc., and the heated plastic is in the extruder. Impurities in the plastic after heating will be filtered out through a filter. The filter is a circular cross-section and installed at the end of the extruder discharge. After the filtered plastic melt passes through the membrane head, it can be obtained It has the same di...
