一种挤出机
本实用新型的发明涉及一种挤出机，尤其是通过双螺杆连续啮合，输送、挤出胶料直接进行胶料压延的挤出机。
目前橡胶加工行业所使用的挤出机，其推进螺杆采用单柱或双柱型推进，使胶料输送挤出后再至专用压延机进行压延。这种挤出机挤出胶料的能力弱，胶料的流动不顺畅，生产效率低，质量不稳定。
本实用新型的发明，是提供一种新型挤出机，它能够使螺杆输送，挤出胶料的能力大大增强，并使胶料流动顺畅，直接进行压延，从而提高胶料的加工效率及质量。
为实现上述任务，本实用新型的发明采用的解决方案是：采用双锥型双螺杆，两螺杆带夹角安装，其螺杆螺旋结构是单头、不等距、不等深、收剑式，整体啮合；机筒的底部呈下坡式结构使胶料流动顺畅，在机筒胶料出口处设置滚式机头，实现胶料的挤出和压延一次完成，从而达到提高胶料输送、挤出、压延效率和质量的目的。
下面结合附图和实施例对本实用新型的发明作进一步详细说明。
