Abstract

一种防横向变形的发泡机流道板,其特点是在流道板体上的发泡机筒的顶部开有进料口,流道从侧面绕到发泡机筒上面与进料口相通。它解决了发泡原料从一侧进入发泡机筒,横向两侧温度不一致,影响产品质量的问题,适应各种发泡板材生产机械配装使用。

Description

防横向变形流道板
技术领域
本发明涉及发泡板材的生产机械领域,具体地说是一种发泡机配用的流道板。
背景技术
在发泡板材生产过程中,对温度的要求非常严格,稍有差别都会影响产品质量。目前的发泡机流道板,熔融的发泡原料都是从一侧横向进入发泡机筒的,因此,流道一侧发泡原料的温度必然比另一侧高,容易造成产品板材左右变形。
发明内容
本发明为解决发泡原料从一侧进入发泡机筒,横向两侧温度不一致,影响产品质量的问题,设计一种使原料从上方进入的发泡机流道板。
本发明的技术方案是,一种防横向变形流道板,其特殊之处是,在流道板体上的发泡机筒的顶部开有进料口,流道从侧面绕到发泡机筒上面与进料口相通。
熔融的发泡原料经过流道从上面竖向进入发泡机筒,保证了原料在机筒内横向两侧的温度平衡,发泡原料从机头中出来的同时完成发泡,避免了发泡板材从发泡机中出来时左右变形,保证了产品质量。
本发明的技术效果是,采用上述的技术方案,可以实现一种结构简单,质量稳定的发泡机流道板。
附图说明
图1是本发明的结构主视图,并作摘要附图。
图2是本发明结构俯视图。
图3是本发明结构左视图。
在图中,1流道板体、2发泡机筒、3进料口、4流道。
具体实施方式
下面结合附图实施例,对本发明进一步说明。
如图所示,在流道板体1上的发泡机筒2的顶部开有进料口3,流道4从侧面绕到发泡机筒2上面与进料口3相通。
熔融的发泡原料经过流道4从上面进入发泡机筒2,保证了原料在发泡机筒2内横向两侧温度的平衡,发泡原料从机头中出来的同时完成发泡,避免了发泡板材从发泡机中出来时左右变形。
