Description

一种螺旋挤出机用搭接螺杆
技术领域
本实用新型涉及一种螺旋挤出机用搭接螺杆,属于塑化挤出成型工艺领域。
背景技术
通常,塑化挤出成型工艺采用双螺杆挤出机成型或单螺杆挤出机成型,这两种挤出装置用螺杆均是整体结构,采用一次加工形成,螺纹结构简单,仅实现简单的塑化、混合、成型功能,对物料的适用范围窄,对于物料特性越来越复杂的物料来说,传统的螺杆螺纹结构已不能适用,要求设计出具有不同功能段的螺杆。而根据物料特性设计出的整体螺杆,由于结构复杂,加工技术要求高,难于加工。即使采用新加工技术加工成适于物料特性的螺杆,其适用的柔性差,使用的经济性不高。
实用新型内容
本实用新型的目的是解决传统挤出机用整体结构的螺杆加工技术要求高、对物料的适用范围窄等缺点,而提供一种螺旋挤出机用搭接螺杆。
本实用新型的目的是通过以下技术方案实现的:
本实用新型的一种螺旋挤出机用搭接螺杆,包括:螺杆芯轴、功能螺套、螺杆头;
螺杆芯轴为多个分件搭接而成,每个芯轴分件外壁均加工有花键槽,且每个芯轴的两端分别加工有相互匹配的花键头和花键套,最前端的芯轴分件的前端内壁加工有连接螺纹;
功能螺套的中心加工有与螺杆芯轴外壁相匹配的花键槽,每个功能螺套的外形分别与传统挤出机用螺杆上起到各种功能处的外形相匹配;
各个芯轴分件首尾相接组成一根螺杆芯轴,按照工艺顺序将各个功能螺套花键连接在在螺杆芯轴上,螺杆芯轴的后端与驱动装置通过花键连接,螺杆芯轴的前端通过螺纹连接螺杆头,使各个功能螺套在螺杆芯轴上轴向定位。
有益效果
本实用新型通过积木式搭接螺纹螺杆,解决传统整体结构的挤出机用螺杆加工技术要求高、对物料的适用范围窄等问题。通过对螺杆长度、螺纹结构的可调节,实现对不同物料加工,降低了螺杆的加工难度大及制造成本。该装置的适用范围广,具有广泛的应用前景。
附图说明
图1为本实用新型搭接螺杆的结构示意图;
图2为本实用新型搭接螺杆中两个芯轴分件的搭接示意图;
图3为本实用新型搭接螺杆中功能螺套的轴向视图;
其中,1-螺杆头;2-功能螺套;3-螺杆芯轴。
具体实施方式
下面结合附图和实施例对本实用新型的内容作进一步描述。
实施例
本实用新型的一种螺旋挤出机用搭接螺杆,如图1所示,包括:螺杆芯轴3、功能螺套2、螺杆头1;
如图2所示,螺杆芯轴3为多个分件搭接而成,每个芯轴分件外壁均加工有花键槽,且每个芯轴的两端分别加工有相互匹配的花键头和花键套,最前端的芯轴分件的前端内壁加工有连接螺纹;
如图3所示,功能螺套2的中心加工有与螺杆芯轴3外壁相匹配的花键槽,每个功能螺套2的外形分别与传统挤出机用螺杆上起到各种功能处的外形相匹配;
各个芯轴分件首尾相接组成一根螺杆芯轴3,按照工艺顺序将各个功能螺套花键连接在在螺杆芯轴3上,螺杆芯轴3的后端与驱动装置通过花键连接,螺杆芯轴3的前端通过螺纹连接螺杆头1,使各个功能螺套在螺杆芯轴3上轴向定位。
