Description

塑料吹瓶机热灌装拉伸杆连接装置
技术领域
本发明涉及一种塑料吹瓶机热灌装拉伸杆连接装置,属于塑料机械领域。
背景技术
采用塑料吹瓶机生产塑料中空容器,特别是采用热灌装的饮料瓶时,在吹瓶过程中,有一个工艺过程是要吹冷气定型,叫二次吹气,二次吹气是通过空心的拉伸杆来导气完成的。现有技术的吹瓶机空心拉伸杆是通过接头直接接到拉伸杆的尾部,接头再与外接高压管相连。其存在的缺点是:一、因为拉伸杆在拉伸时是上、下运动的,外接高压管会通过接头给拉伸杆一个弯曲作用力,由于拉伸杆是空心的,很容易造成拉伸杆弯曲或者折断;二、拉伸杆的尾部与接头连接后,高度不能调整,应用起来很不方便。
发明内容
本发明的目的是为了克服已有技术的缺点,提供一种在拉伸杆外套设进气管,进气管连接接头,拉伸杆不弯曲或者折断,并且拉伸杆在进气管中可调整上下高度,使用方便,拉伸杆与进气管之间密封可靠的塑料吹瓶机热灌装拉伸杆连接装置。
本发明塑料吹瓶机热灌装拉伸杆连接装置的技术方案是:包括拉伸座和拉伸杆,其特征在于所述的拉伸座中安装进气管,拉伸杆设置在进气管中,进气管的上端连接外接头,外接头连接外接高压管,进气管的下端连接固定座,固定座中安有密封座,密封座中安装密封圈和密封垫,密封圈和密封垫与拉伸杆相接触,密封座的外端安有端盖,端盖连接拉伸座。
本发明公开了一种塑料吹瓶机热灌装拉伸杆连接装置,在拉伸座中安装进气管,进气管的上端连接外接头,外接头连接外接高压管,使拉伸杆与外接高压管无连接,拉伸杆上、下运动时不拉扯外接高压管,外接高压管对拉伸杆无弯曲作用力,拉伸杆不弯曲、不折断,使用寿命长,并且拉伸杆设置在进气管中,无硬性连接,拉伸杆可上下调整高度,以适应各种不同高度的吹瓶机模具,节省成本。另一方面,在拉伸杆与进气管之间安装密封圈和密封垫以及密封座,使进气管与拉伸杆之间密封性能好,不漏气,有了固定座和端盖固定,安装牢靠。
本发明的塑料吹瓶机热灌装拉伸杆连接装置,所述的进气管上端经螺纹连接外接头,由螺纹连接方便,进气管下端经螺丝连接固定座,由螺丝连接可靠。所述的端盖经螺钉连接拉伸座,端盖由螺钉连接安装方便、牢靠。
附图说明
图1是本发明塑料吹瓶机热灌装拉伸杆连接装置结构示意图。
