背景技术
在塑料挤出成型设备中，塑料挤出机通常称之为主机，而与其配套的后续设备塑料挤出成型机则称为辅机。塑料挤出机经过100多年的发展，已由原来的单螺杆衍生出双螺杆、多螺杆，甚至无螺杆等多种机型。
但是目前市面上的塑料挤出机挤出的塑料成品质量不高，因为在挤出过程中，原料搅拌混合不均匀，加热不充分，导致其质量不高，而且现有的挤出机也存在自动化程度不高的问题。
发明内容
为要解决的上述问题，本发明提供一种塑料挤出机搅拌加热装置。
本发明的技术方案：一种塑料挤出机搅拌加热装置，其特征在于包括动力装置、轴承组件、搅拌装置、加热装置、输送加热筒、温度传感器和控制显示器，所述动力装置设置在所述输送加热筒前部并所述通过所述轴承组件与所述搅拌装置连接，所述搅拌装置包括2根螺杆，所述螺杆包括搅拌轴和螺纹结构，所述搅拌轴采用空心结构，所述搅拌轴设置有蒸汽导入装置和冷凝水导出装置，所述螺纹结构以所述搅拌轴为轴心设置，所述搅拌装置设置在输送加热桶内，所述加热装置包缚在输送加热筒外，所述温度传感器设置在输送加热筒中部和尾部，所述控制显示器7设置在所述动力装置1上。
所述动力装置包括驱动电机和减速器，所述减速器与所述驱动电机连接并设置在所述驱动电机上部。
所述轴承组件采用错位布置结构。
所述输送加热筒为卧式圆柱型容器，包括筒体、称重加料斗、排料口，所述称重加料斗设置在所述筒体前端顶部，所述排料口设置在所述筒体尾端中心位置。
所述加热装置采用电磁感应加热，所述加热装置外加设保温层。
所述筒体包括夹套和内筒，所述夹套设置有蒸汽导入装置。
本发明的有益效果：结构简单，设计合理，输送加热筒内的搅拌装置，使受热均匀能并向前输送，其自身又具有加热功能，可增加换热面积，提高换热效率，加快了输送加热筒原材料混合、熔化和输送速度。
