Abstract

拉幅定型机喷风嘴,包括拉幅定型机风管(1),拉幅定型机风管(1)上成型有若干个方形的吹风孔(2),方形的吹风孔(2)下部成型有分风片(3)。它在吹风孔的下部设置有分风片,使得热风从吹风孔中吹出时被打散,这样分布到布料上的热风更均匀。

Description

拉幅定型机喷风嘴
技术领域:
本实用新型涉及拉幅定型机技术领域,更具体地说涉及一种拉幅定型机喷风嘴。
背景技术:
现有拉幅定型机喷风嘴由风管和泄流板构成,风管为渐次缩小的筒状。风管的横截面一般呈方形,在风管的表面分布有若干个圆形的吹风孔,其不足之处是:圆形的吹风孔在风力较大时,热风直接急带从吹风孔中吹出,使得热风不能够较为均匀地分布在布料上,从而影响拉幅定型机的定型效果。
实用新型内容:
本实用新型的目的就是针对现有技术之不足,而提供拉幅定型机喷风嘴,它在吹风孔的下部设置有分风片,使得热风从吹风孔中吹出时被打散,这样分布到布料上的热风更均匀。
本实用新型的技术解决措施如下:
拉幅定型机喷风嘴,包括拉幅定型机风管,拉幅定型机风管上成型有若干个方形的吹风孔,方形的吹风孔下部成型有分风片。
所述方形的吹风孔冲压成型在风管上,分风片冲压成型在吹风孔的下部。
所述分风片表平面与风管的轴线的夹角为30~60度。
本实用新型的有益效果在于:
它在吹风孔的下部设置有分风片,使得热风从吹风孔中吹出时被打散,这样分布到布料上的热风更均匀。
附图说明:
图1为本实用新型的结构示意图
图2为吹风孔处的立体放大图
图中:1、拉幅定型机风管; 2、吹风孔;3、分风片。
具体实施方式:
实施例:见图1所示,拉幅定型机喷风嘴,包括拉幅定型机风管1,拉幅定型机风管1上成型有若干个方形的吹风孔2,方形的吹风孔2下部成型有分风片3。
所述方形的吹风孔2冲压成型在风管1上,分风片3冲压成型在吹风孔2的下部。
所述分风片3表平面与风管1的轴线L的夹角a为30~60度。
工作原理: 当热风进入拉幅定型机风管1中后,经过分风片3打散再从方形的吹风孔2中吹向布料,这样吹出来的风更均匀,使得拉幅定型机的定型效果更好。
