                 Abstract: The blanking of the extruder is added to the extruder by the gravity of the material itself. Since
             the diameter of the hopper is generally gradually reduced, it is easy to cause material accumulation and
             compaction at the feed opening, resulting in "bridging" without blanking. In order to better meet the normal
             blanking of the extruder, a forced ramming / stirring and anti-blocking device is designed in the middle of
             the blanking hopper to solve the phenomena of stratification, uneven mixing and "bridging" during blanking.
             Practice shows that the design of the anti-blocking device can adapt to plastic raw materials of various
             volumes and shapes, meet the blanking requirements of the extruder, and improve the production efficiency
             of the plastic extruder.
