Description

一种改进的挤出螺杆
技术领域
    本实用新型涉及螺杆技术领域，尤其涉及一种改进的挤出螺杆。 
背景技术
目前，现有技术中挤出机螺杆中一般只具有送料的作用，在进行挤出物料的过程中，由于物料是成不规则的轨迹流到机筒内的，这样时常会出现，物料的流速出现时快时慢的现象，故物料容易产生停滞或物料流速过快，未能彻底塑化的情况，这样会严重影响物料的挤出质量。 
实用新型内容
本实用新型的目的在于提供一种改进的挤出螺杆，其具有能保证物料匀速流动，流动轨迹有规律且顺畅，不会影响物料挤出质量的特点。 
为实现上述目的，本实用新型采用下述技术方案： 
一种改进的挤出螺杆，包括进料段、熔融塑化段以及挤出段，所述进料段、熔融塑化段以及挤出段的螺纹均轴向开设有若干导流孔，进料段、熔融塑化段以及挤出段的螺纹外边均延伸地设有导流延边。
其中，所述导流孔为与导流延边对应开设的倾斜孔，倾斜孔与挤出螺杆的轴线之间夹角为45°。 
采用上述结构后，本实用新型的有益效果：本实用新型包括进料段、熔融塑化段以及挤出段，所述进料段、熔融塑化段以及挤出段的螺纹均轴向开设有若干导流孔，进料段、熔融塑化段以及挤出段的螺纹外边均延伸地设有导流延边，本实用新型通过在所述进料段、熔融塑化段以及挤出段的螺纹均轴向开设有若干导流孔，以及在螺纹外边均延伸地设有导流延边，可使物料按照规定的运动轨迹流动，这样能保证物料匀速流动，流动轨迹有规律且顺畅，不会影响物料挤出质量。 
附图说明
图1为本实用新型的结构示意图。 
图中附图标记包括： 
1、进料段；                 2、熔融塑化段；      
3、挤出段；                 4、导流孔；
5、导流延边。
具体实施方式
以下结合附图对本实用新型进行详细的描述。 
如图1所示，一种改进的挤出螺杆，包括进料段1、熔融塑化段2以及挤出段3，所述进料段1、熔融塑化段2以及挤出段3的螺纹均轴向开设有若干导流孔4，进料段1、熔融塑化段2以及挤出段3的螺纹外边均延伸地设有导流延边5，所述导流孔4为与导流延边5对应开设的倾斜孔，倾斜孔与挤出螺杆的轴线之间夹角为45°。通过在所述进料段1、熔融塑化段2以及挤出段3的螺纹均轴向开设有若干导流孔4，以及在螺纹外边均延伸地设有导流延边5，导流延边5可延伸出螺纹外边，以扩大物料的流动空间，本实用新型可使物料按照规定的运动轨迹流动，这样能保证物料匀速流动，流动轨迹有规律且顺畅，可避免物料倒流，不会影响物料挤出质量。 
以上内容仅为本实用新型的较佳实施例，对于本领域的普通技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本实用新型的限制。
