Description
Technical field
The utility model relates to a kind of feed cylinder of extruder, what be specifically related to is a kind of bi-conical feed cylinder that is applied in the double screw extruder.
Background technology
Double screw extruder has two screw rods to rotate in " ∞ " font heating cylinder.Screw rod can be divided into engagement and non-engagement type; Combination and non-combined type; Rotation and antidromous in the same way.So that engagement type and incorgruous engagement type are used morely in the same way.The former is used for plastic blend, filling and enhancing, produces various batches; The latter is used to process the PVC-U goods.
The conical double screw extruder machine barrel mainly is made up of cylindrical shell and twin-screw, this cylindrical shell generally with heat-resisting, compressive resistance is higher, the composite steel tube of firm wear-resisting, corrosion resistant steel alloy or liner steel alloy is made.The cross section of cylindrical shell endoporus is two crossing circular holes, is loaded on conical double-screw it in from the linear change that diminishes greatly with cooperation along axis, it is used to realize the pulverizing to plastics, softening, fusion, plasticizing, exhaust and compacting, and evenly carries sizing material continuously to formation system.The length of general cylindrical shell is 15～30 times of its diameter, so that plastics are fully heated and abundant plasticizing is principle.
And the charging aperture operated by rotary motion of existing double screw extruder cylindrical shell at an upper portion thereof, is connected with feeding hopper by charging aperture, and this feeding hopper relies on the gravity of material to carry out the cylindrical shell continuous flow rate, and what promptly adopt is the continuous flow rate that the mode of dead-weight feeding realizes material.But this mode feeding, when running into the bulk material, common feeding hopper just can't be fed into the material of these bulks in the double screw extruder evenly, continuously, has influence on normally carrying out of production; Thereby have the forced feed machine on the market, but the installation of the charging aperture incompatibility forced feed machine of existing double screw extruder cylindrical shell, the especially incompatible use that connects the conical double-screw forced feed has increased maintenance cost, has influence on normally carrying out of production.
