一种双层热风筒
本技术涉及一种热风筒,尤其涉及一种用于热风熔接机的双层热风筒。
技术介绍
在完成塑料复膜编织布的生产之后,有时需要根据客户的需求,进行一些下游工序,例如,将塑料复膜编织布进行拼接,或者,对塑料复膜编织布的两侧边进行卷筒及穿绳等。目前,在塑料复膜编织布的拼接、侧边卷筒及穿绳的生产中,一般采用热风熔接机对塑料复膜编织布进行熔接热合,其主要部件热风筒一般为单层结构,热风筒一般包括筒体、电热元件和风嘴,电热元件安装在筒体中,筒体的上端设有密封端盖,筒体的上部设有进风口,筒体的下端设有出风口,风嘴安装在出风口处,通过设置在筒体中的电热元件对气流进行加热输出热风,由于直过式的加热方式及散热较快的原因,造成能耗较大,更重要的是,直过式的加热方式,风速不能太快,因此,导致热风的输出速度较慢,从而导致生产速度较慢。
技术实现思路
