实用新型内容
为实现以上所述，本实用新型提供一种塑化机螺杆结构，该螺杆结构简单，螺杆均为分段结构，便于安装，由于螺杆的特殊结构形式，带来产品质量的提高和生产效率的提高。
为解决以上技术问题，本实用新型提供如下技术方案：一种塑化机螺杆结构，所述螺杆结构为分段结构，所述螺杆从螺杆头开始依次包括均化段螺杆、熔融段螺杆、输送段螺杆、过渡段螺杆和进料段螺杆，所述进料段螺杆的直径小于其它各段螺杆的直径，该段螺杆与机筒之间的空间较其它各段螺杆与机筒间的空间大，所述进料段螺杆连接减速器输出轴。
进一步地，所述熔融段螺杆的螺纹为右旋螺纹，螺纹角为0-45°。
进一步地，所述均化段螺杆的螺纹旋向与熔融段螺杆的螺纹旋向相反。
进一步地，所述输送段螺杆的长度大于熔融段和塑化段螺杆的长度。
    本实用新型涉及的这种塑化机螺杆结构，结构简单，方便制造与安装，能够有效的完成螺杆在各个分段的不同任务，提高产品质量。
附图说明
图1是本实用新型塑化机螺杆结构示意图；
1-螺杆头；2-均化段螺杆；3-熔融段螺杆；4-输送段螺杆；5-过渡段螺杆；6-进料段螺杆；7-减速器输出轴。
具体实施方式
如图1所示，螺杆结构为分段结构，螺杆从螺杆头1开始依次包括均化段螺杆2、熔融段螺杆3、输送段螺杆4、过渡段螺杆5和进料段螺杆6，进料段螺杆6的直径小于其它各段螺杆的直径，该段螺杆与机筒之间的空间较其它各段螺杆与机筒间的空间大，进料段螺杆6连接减速器输出轴7。
熔融段螺杆3的螺纹为右旋螺纹，螺纹角为0-45°。
均化段螺杆2的螺纹旋向与熔融段螺杆3的螺纹旋向相反。
输送段螺杆4的长度大于熔融段和塑化段螺杆的长度。
过渡段螺杆5为输送段螺杆4与进料段螺杆6之间的过渡段螺杆，该段螺杆为锥形面，为螺杆直径由大变小的过渡坡面。
本实用新型所述的具体实施方式并不构成对本申请范围的限制，凡是在本实用新型构思的精神和原则之内，本领域的专业人员能够作出的任何修改、等同替换和改进等均应包含在本实用新型的保护范围之内。
