Description

挤出机用螺杆
技术领域
[0001] 本实用新型涉及挤出机用螺杆。
背景技术
[0002] 螺杆作为挤出机中的最主要部件,它直接关系到挤出机的应用范围和生产效率, 由高强度耐腐蚀的合金钢制成,螺杆按功能分为三段,分别是进料段、压缩段、计量段,目前的螺杆进料段都是单螺纹,进料量和进料效率都不太高。
实用新型内容
[0003] 本实用新型的目的在于提供挤出机用螺杆,能够有效解决目前螺杆进料量和进料效率都不高的问题。
[0004] 为了解决上述技术问题,本实用新型是通过以下技术方案实现的:挤出机用螺杆, 包括进料段、压缩段、计量段,所述进料段上设有双螺纹,所述压缩段、计量段为单螺纹。
[0005] 优选的,所述进料段的双螺纹为矩形螺纹;具有较好的进料效果,不会使材料被挤
出ο
[0006] 优选的,所述进料段的螺距为3〜5cm ;能达到较高输送能力的螺距。
[0007] 优选的,所述进料段长度为30〜35cm ;进料段长度过长增加了制造成本,长度过短无法满足进料需要。
[0008] 优选的,所述压缩段、计量段的螺纹也为矩形螺纹,螺距为进料段螺纹螺距的两倍;方便螺杆的制造。
[0009] 与现有技术相比,本实用新型的优点是:进料段采用双螺纹,提高了输送能力,提高了产量和生产效率。
附图说明
[0010] 图1为本实用新型挤出机用螺杆的结构示意图。 具体实施方式
[0011] 参阅图1为本实用新型挤出机用螺杆的实施例,挤出机用螺杆,包括进料段1、压缩段2、计量段3,所述进料段1上设有双螺纹,所述压缩段2、计量段3为单螺纹,所述进料段1的双螺纹为矩形螺纹,所述进料段1的螺距为3〜5cm,所述进料段1长度为30〜35cm, 所述压缩段2、计量段3的螺纹也为矩形螺纹,螺距为进料段1螺纹螺距的两倍。
[0012] 在进料段1设置双螺纹,提高了输送能力,提高了产量和生产效率。
[0013] 以上所述仅为本实用新型的具体实施例,但本实用新型的技术特征并不局限于此,任何本领域的技术人员在本实用新型的领域内,所作的变化或修饰皆涵盖在本实用新型的专利范围之中。
