Description

带压力调节的螺杆挤出机
技术领域
本实用新型涉及一种带压力调节的螺杆挤出机，属于塑料设备领域。 
背景技术
螺杆挤出机主要用于生产塑料制品，是国民经济中不可缺少的一部分，一般通过模具进行样品成型，就可以作为塑料制品进行使用了，但在挤压末端经常回残留一定的余量边角料而无法去除，影响美观和使用，目前是一个急需解决的问题。 
发明内容
本实用新型的目的是提供一种带压力调节的螺杆挤出机。 
本实用新型要解决的问题是现有挤出机挤压末端有残留的不足。 
为实现本实用新型的目的，本实用新型采用的技术方案是： 
带压力调节的螺杆挤出机，包括主体、料筒、伺服电机、液压定量泵、液压缸、压力调节筒和挤出模头，所述主体上安装有料筒，料筒上设有伺服电机、液压定量泵、压力调节筒，料筒左端安装有挤出模头，液压缸安装在压力调节筒上，伺服电机通过转轴和液压定量泵相连接，液压定量泵通过管路和液压缸相连接。
所述液压缸的伸缩轴安装在压力调节筒内。 
所述压力调节筒直接与料筒内的螺杆相连通。 
本实用新型的优点是：本装置只要在料筒的末端加设压力调节装置，可有效防止残留，生产的塑料制品光滑圆润，同时也节省了材料，应具有广泛的市场前景。 
附图说明
图1是本实用新型带压力调节的螺杆挤出机的立体图； 
图中：1、主体     2、料筒      3、伺服电机      4、液压定量泵      5、液压缸6、压力调节筒     7、挤出模头。
具体实施方式
下面结合附图及实施例对本实用新型作进一步的说明。 
带压力调节的螺杆挤出机，包括主体1、料筒2、伺服电机3、液压定量泵4、液压缸5、压力调节筒6和挤出模头7，所述主体1上安装有料筒2，料筒2上设有伺服电机3、液压定量泵4、压力调节筒6，料筒2左端安装有挤出模头7，液压缸5安装在压力调节筒6上，伺服电机3通过转轴和液压定量泵4相连接，液压定量泵4通过管路和液压缸5相连接。 
所述液压缸5的伸缩轴安装在压力调节筒6内，在调节筒6内拉升用于调节末端的挤出压力。 
所述压力调节筒6直接与料筒2内的螺杆相连通，可以瞬间调节螺杆挤出压力；压力调节筒6安装在料筒2的末端处。 
本实用新型的使用方法：当产品挤出完成时，根据实际情况，伺服电机3以一定的转动量带动液压定量泵4工作，液压缸5迅速收缩，降低料筒2内挤出压力，就不会多挤出塑料，使得挤出的产品不会带残留。
