Abstract

本发明涉及一种挤压机模头结构，包括模头本体，模头本体上开设有圆环形的内窄外宽的模孔，模孔的开口处安装有带有挤出孔的模板，靠近模孔的模头本体内开设有热媒流道，模板背面安装有控制模头压力的压力传感器。本发明的有益效果是：通过压力传感器，确保模头每一个模孔的出料量和出料速度完全一样，物料喷出后在切粒机水室的冷却效果才能相同，防止因模孔出料量小而被过度冷却造成碎屑增加。

Description

挤压机模头结构
技术领域
本发明涉及一种挤压机模头结构。
背景技术
当物料进入模头后如果压力不足，模头上部物料被挤出的速度就比下部慢，条形也比下部细。被切粒水冷却后更硬，切刀切粒时产生的碎屑量将增大。
发明内容
本发明要解决的技术问题是：基于上述问题，本发明提供一种挤压机模头结构。
本发明解决其技术问题所采用的一个技术方案是：一种挤压机模头结构，包括模头本体，模头本体上开设有圆环形的内窄外宽的模孔，模孔的开口处安装有带有挤出孔的模板，靠近模孔的模头本体内开设有热媒流道，模板背面安装有控制模头压力的压力传感器。
本发明的有益效果是：通过压力传感器，确保模头每一个模孔的出料量和出料速度完全一样，物料喷出后在切粒机水室的冷却效果才能相同，防止因模孔出料量小而被过度冷却造成碎屑增加。
附图说明
下面结合附图对本发明进一步说明。
图1是本发明的结构示意图。
其中：1.模头本体，2.模孔，3.模板，4.热媒流道，5.压力传感器。
具体实施方式
现在结合具体实施例对本发明作进一步说明，以下实施例旨在说明本发明而不是对本发明的进一步限定。
如图1所示的一种挤压机模头结构，包括模头本体1，模头本体1上开设有圆环形的内窄外宽的模孔2，模孔2的开口处安装有带有挤出孔的模板3，靠近模孔2的模头本体1内开设有热媒流道4，模板3背面安装有控制模头压力的压力传感器5。
挤压切粒时，通过控制热媒流道内热媒的温度和流速，从而使得模孔内的物料保持熔融状态。同时，通过压力传感器，感知流通中物料的压力，从而保证模头压力在10～15MPa之间，确保模头每一个模孔的出料量和出料速度完全一样，物料喷出后在切粒机水室的冷却效果才能相同，防止因模孔出料量小而被过度冷却造成碎屑增加。
以上述依据本发明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发明技术思想的范围内，进行多样的变更以及修改。本项发明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。
