Description

双机头挤塑机
技术领域
本实用新型涉及一种挤塑机，具体涉及一种双机头挤塑机。 
背景技术
在塑料挤出成型设备中，塑料挤出机通常称之为主机，而与其配套的后续设备塑料挤出成型机则称为辅机。塑料挤出机经过100多年的发展，已由原来的单螺杆衍生出双螺杆、多螺杆，甚至无螺杆等多种机型，目前以单螺杆挤出机应用最为广泛，塑料挤出机（主机）可以与管材、薄膜、捧材、单丝、扁丝、打包带、挤网、板（片）材、异型材、造粒、电缆包覆等各种塑料成型辅机匹配，组成各种塑料挤出成型生产线，生产各种塑料制品。因此，塑料挤出成型机械无论现在或将来，都是塑料加工行业中得到广泛应用的机种之一，挤塑机由挤压系统、传动系统和加热冷却系统组成。 
挤塑机是利用特定形状的螺杆，在加热的机筒中旋转，将由斗料中送来的塑料向前挤压，使塑料均匀的塑化，通过机头和不同形状的模具，使塑料挤压成连续性的所需要的各种形状的塑料。在实际生产中，一方面经常出现更换生产型号，换模具，或者机头损坏维修等一系列问题导致机器停机闲置，造成资源浪费，大大降低了生产的效率，另一方面，单机头的挤出机，效率比较低，而投入更多的挤出机，从企业控制成本角度来讲，是不经济的。 
实用新型内容
本实用新型要解决的技术问题是：为了避免更换模具，机头维修，单机头生产效率低下的问题，本实用新型提供一种双机头挤塑机，利用两个机头来提高生产效率。 
本实用新型解决其技术问题所采用的技术方案是：一种双机头挤塑机，包括螺杆挤出机，所述的螺杆挤出机的出料端设有两个挤出模头，所述的螺杆挤出机与两个挤出模头之间具有一个物料分配器，所述的物料分配器内具有两个流道，两个流道分别连通两个挤出模头，所述的两个流道上均设有控制阀。 
为了便于控制，所述的控制阀，包括2个球阀，分别独立控制两个流道。 
为了出料更加均匀，物料分配器中的两个流道呈人字形对称分布，两个挤出模头对称设置在物料分配器上。 
本实用新型的有益效果是，本实用新型采用双机头设计，能够有效的提高生产效率，控制成本。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
图1是本实用新型双机头挤塑机最优实施例的结构示意图。 
图2是双机头挤塑机物料分配器和机头的局部放大图。 
图中1、螺杆挤出机，2、挤出模头，3、物料分配器，4、控制阀。 
具体实施方式
现在结合附图对本实用新型作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本实用新型的基本结构，因此其仅显示与本实用新型有关的构成。 
本实用新型所述的双机头挤塑机，包括螺杆挤出机1，螺杆挤出机1的出料端设有两个挤出模头2，螺杆挤出机1与两个挤出模头2之间具有一个物料分配 器3，物料分配器3内具有两个流道，两个流道分别连通两个挤出模头2，两个流道上均设有控制阀4，控制阀4包括2个球阀，分别独立控制两个流道，物料分配器3中的两个流道呈人字形对称分布，两个挤出模头2对称设置在物料分配器3上。 
在实际生产过程中，当其中一个机头需要更换模具，或者维修时，我们可以关闭控制该机头的阀门，通过另一个机头继续使用，当生产量大的时候，我们可以同时打开两个阀门，两个机头一起工作。 
以上述依据本实用新型的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项实用新型技术思想的范围内，进行多样的变更以及修改。本项实用新型的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
