Environment-friendly stone paper extrusion forming screw, extruder and stone paper production process
The invention relates to an environment-friendly stone paper extrusion forming screw. The environment-friendly stone paper extrusion forming screw comprises a shaft portion, a connecting handle arranged at the end of the shaft portion and used for being connected to extrusion equipment and a thread arranged on the shaft portion. A pressure stabilization segment is arranged on the screw. A shaft portion of the pressure stabilization segment is equal in diameter, a thread of the pressure stabilization segment is equal in pitch, a chamfer R2 on the rear side of the thread of the pressure stabilization segment is 2-3 times the angle of a chamfer R1 on the front side, the radius range corresponding to the chamfer R1 on the front side of the thread of the pressure stabilization segment is 3-7 mm, and the radius range corresponding to the chamfer R2 on the rear side is 6-19 mm. The invention relates to an environment-friendly stone paper extruder which comprises a screw and a screw barrel. The invention further relates to a stone paper production process. The environment-friendly stone paper extrusion forming screw, the environment-friendly stone paper extruder and the stone paper production process have good dispersity to materials, the stable extrusion quantity and extrusion pressure and are especially suitable for extrusion production of stone paper formula materials.
本发明涉及一种环保石头纸挤出成型螺杆，包括轴部、设置在轴部端部的用于连接至挤出设备的连接柄及设置在轴部上的螺纹，螺杆上设置有稳压段；所述稳压段的轴部等直径，螺纹等螺距，稳压段的螺纹后侧倒角R2是前侧倒角R1角度的2～3倍，稳压段的螺纹的前侧倒角R1所对应的半径范围为3～7mm，后侧倒角R2所对应的半径范围为6～19mm。本发明涉及一种环保石头纸挤出机，包括螺杆和螺筒。本发明还涉及石头纸的生产工艺。本发明具有良好的对物料的分散性、稳定的挤出量和挤出压力，尤其适用于石头纸配方材料的挤出生产。
