Abstract

本发明是一种专门用于喷气织机的六孔辅助喷嘴，如图1所示。专门用于高速稳定引纬。克服了19孔、9孔等多孔辅喷嘴小孔被堵塞，每年要清洗，制造成本高以及单孔喷嘴引纬容易拉断纬纱，对长丝的包容性差，引纬相对多孔不够稳定的缺点，而且耗气量显著降低。

Description

一种喷气织机六孔辅助喷嘴
技术领域
本发明属于纺织机械制造领域，设计一种新型的辅助喷嘴形式，能够克服多孔喷嘴气流堵塞等缺点，保证引纬过程的顺利进行，同时相比单孔、双孔喷嘴具有一定的节能优势。 
背景技术
目前喷气织机辅喷嘴有多孔、单孔、双孔等。多孔的类型有19孔、9孔和7孔，还有矩型孔，五星型（现在极为少见）。多孔缺点是小孔被堵塞，每年要清洗，而且制造成本高，耗气高。单孔、双孔的缺点是引纬相对多孔空气速度较快，对纱线要求相对高，容易拉断纬纱，对长丝的包容性差，引纬相对多孔不够稳定。这些问题一直困扰织机制造商和使用喷气织机的纺织厂。 
发明内容
本发明的目的是提供一种引纬可靠、效率高、耗气量小的辅喷嘴。本发明技术措施如下：喷气孔由六个小孔组成，其侧面尺寸a、顶部的小孔边缘与顶端的距离b以及顶部圆弧半径R都比现有的喷嘴主体小。 
本发明的优点是在织布引纬过程中，气体流相对单孔或多孔更加柔和，气流面积较大，对纱线无过度拉伤，而且对纱线的包容性好，使引纬更加稳定。速度快，空气集束性好，制造成本低，耗气量显著下降。 
附图说明
图1为六孔辅助喷嘴主体的主视图。 
图2为六孔辅助喷嘴的左视图。 
具体实施方式
辅喷嘴上六个孔呈梅花形分布，最顶部的孔上边缘与顶端的距离b不大于0.6mm，喷嘴主体的侧面宽度a不大于2.2mm，顶部转接圆弧R不大于0.15mm。
