Abstract

一种塑料挤出螺杆，涉及塑料加工机械，其特征在于：螺杆采用三段式结构，依次为加料段、熔融段、挤出段，加料段采用单头螺纹结构，熔融段采用双头螺纹的分离型结构，挤出段采用混炼型结构。本实用新型装在挤出机上，配合开槽加料衬套，产量比普通螺杆高出30％-40％。螺杆长径比较大，为34，分为加料段、熔融段和挤出段三段；加料段采单头螺纹的结构，有利于物料的高速稳定输送；熔融段采用双头螺纹的分离型结构，有利于物料的熔融塑化；挤出段采用混炼型的结构，有利于物料的混炼和高产挤出，产量可达350-400kg/h，可与国外一流公司相比。

Description

一种塑料挤出螺杆
技术领域
[0001] 本实用新型涉及塑料加工机械，具体涉及一种塑料挤出螺杆。 背景技术
[0002] 在PE塑料管材挤出领域，目前国内常用的挤出机中，产量都比较低，无法满足大口径管材的生产需要。以65单螺杆挤出机为例，一般厂家生产的65单螺杆挤出机的产量通常在120-160kg/h，好一点的厂家生产的65单螺杆挤出机的产量通常在200-250kg/h，这个产量远低于国外的先进水平。
实用新型内容
[0003] 本实用新型所要解决的技术问题在于提供一种结构简单，产量高的塑料挤出螺杆。
[0004] 本实用新型所要解决的技术问题采用以下技术方案来实现，
[0005] 一种塑料挤出螺杆，其特征在于：螺杆采用三段式结构，依次为加料段、熔融段、挤出段，加料段采用单头螺纹结构，熔融段采用双头螺纹的分离型结构，挤出段采用混炼型结构。
[0006] 所述熔融段的长度为加料段的1. 5〜2倍。
[0007] 所述挤出段的螺纹采用齿轮结构。
[0008] 本实用新型的有益效果是：本实用新型装在挤出机上，配合开槽加料衬套，产量比普通螺杆高出30% -40%。螺杆长径比较大，为34，分为加料段、熔融段和挤出段三段；加料段采单头螺纹的结构，有利于物料的高速稳定输送；熔融段采用双头螺纹的分离型结构， 有利于物料的熔融塑化；挤出段采用混炼型的结构，有利于物料的混炼和高产挤出，产量可达350-400kg/h，可与国外一流公司相比。
