The utility model belongs to the technical field of rubber products processing, in particular, relates to a porous extrusion head of a mixer, which comprises a face plate and a back plate in a cylindrical shape, the diameter of the face plate is larger than that of the back plate, and the fixed connection of the face plate and the back plate is concentric; a spherical concave surface is arranged at the center of the face plate, and three to six extrusion outlets are arranged around the center of the spherical concave surface. The cross section of the extrusion exit is rectangular, and the angle between the long edge of the extrusion exit and the radius of the center of the extrusion exit is n, 20 [n < 40]. The technical scheme of the utility model improves the extrusion efficiency of the mixer by designing multiple extrusion outlets on the large plate of the extrusion head. The extrusion outlets are rectangular and uniformly distributed around the center of the face plate, and at a certain angle with the radius passing through the center, so that the extruded rubber embryos have a certain degree of rotation. The extrusion head is designed with external threads on the side of the back of the extrusion head, so that the extrusion head can be easily screwed on the mixer and disassembled.

一种混炼机多孔挤出头
本技术属于橡胶制品加工
,具体而言,涉及一种混炼机多孔挤出头。
技术介绍
混炼是用炼胶机将生胶或塑炼生胶与配合剂炼成混炼胶的工艺,是橡胶加工最重要的生产工艺。混炼是指为了提高橡胶制品的物理机械性能,改善加工成型工艺,降低生产成本,需要在生胶或塑料胶中加入各种配合剂,如填充剂、补强剂、促进剂、硫化剂、防老剂、防焦剂等,这些配合剂有固体、液体等材料,将所加入的各种配合剂分散均匀,确保胶料的性质一致。所以在炼胶机上使各种配合剂均匀地分散到生胶或塑炼胶中的工艺过程称为混炼,经混炼制成的胶料称为混料胶。混炼后的橡胶从挤出口挤出成为胶胚,现有混炼机的挤出头无法调节挤出尺寸,挤出头不方便更换的问题,同时挤出后还需要进行剪裁,限制了生产效率。
技术实现思路
本技术的主要目的在于提供一种混炼机多孔挤出头,以解决现有混炼机挤出头无法调节挤出尺寸,挤出头不方便更换的问题,同时挤出后还需要进行剪裁,大大限制了生产效率。为了实现上述目的,本技术提供了一种混炼机多孔挤出头,所述挤出头包括面盘和背盘,面盘和背盘成圆柱状,面盘的直径大于背盘,面盘和背盘同心的固定连接;面盘中心部位设置有球形凹面,球形凹面内绕着圆心分布有3~6个挤出口,挤出口贯穿面盘和背盘;挤出口的横截面为矩形,挤出口的长边与过挤出口中心的半径所成夹角为n,20°≤n≤40°。进一步地,所述背盘的侧面设置有外螺纹,外螺纹用于将挤出头安装在混炼机上。进一步地,所述球形凹面圆周的面盘上均布有三个固定孔,固定孔用于安装挤出头的时候操作工具发力。进一步地,所述挤出口的长边与过挤出口中心的半径所成夹角n为32°。 ...
