The sheet extrusion line consists of an extruder (single-screw extruder or twin-screw extruder) equipped with a screen changer and a gear pump, followed by a static mixer (sometimes it is sent to the co-extrusion feed head first, and then to the co-extrusion head) . Add or other multiple extrusion units as described above). Send into the flat mold.
Then, cool the paper through 3 (or more) roll paper stacks (paper pickers) and control the temperature, pressure and nip.
Finally, cut the paper into a certain length, roll it into a roll, or perform the second step online.
The single screw plastic extruder in the manufacturing line adopts new type of screw structure featured as stable feeding and uniform fusion mixing, which can reduce energy consumption and increase production output.
The plastic extruder adopts directly connection between motor and reduction gears, which can improve transmission efficiency and reduce speed fluctuation ensuring the stability of extrusion.
The extruder is designed with the melt dosing pump and it can cooperate with precise multi-layer distributor. The flow proportion and blade clearance ratio are all adjustable, which can lead to a more uniform plastic sheet layer.
The total machine adopts PLC control system, which can realize automatic control for parameter setting, date operation, feedback, alarming and other functions.
