Abstract

本发明公开了一种焊接吊环时吊环中心容易对准其底部的顶尖，焊接质量好，工艺简单，且易于实现自动化生产的大输液PP瓶焊接吊环的方法，其工艺步骤为：1)先将吊环焊于未吹塑前的瓶坯底部的顶尖上，2)然后将瓶坯加热，再将瓶坯吹塑成型为大输液PP瓶。

Description

大输液PP瓶焊接吊环的方法
技术领域
本发明属于PP瓶大输液领域，具体涉及到一种大输液PP瓶焊吊环方式的改进。
背景技术
目前大输液PP瓶焊吊环的方式是：先将图5所示的瓶坯加热，再吹塑成型如图1所示，然后将吊环焊于瓶子底部的顶尖上，如图4所示。用此方法焊吊环有以下缺点：瓶子在吹塑成型过程中难免有小部分底部顶尖不居中、甚至有歪斜的现象，所以难以实现自动化操作；有的瓶子底部顶尖歪斜严重得甚至无法安放吊环，造成瓶子报废；同时由于瓶子的刚性不好，熔焊施压时易发生弹性变形，影响焊接质量。
发明内容
本发明所要解决的技术问题是克服上述现有技术的缺陷，提供一种焊接吊环时吊环中心容易对准其底部的顶尖，焊接质量好，工艺简单，且易于实现自动化生产的大输液PP瓶焊接吊环的方法。
为解决上述技术问题，本发明采用下述技术方案。
本发明大输液PP瓶焊接吊环的方法，其特征在于其工艺步骤为：
1)先将吊环焊于未吹塑前的瓶坯底部的顶尖上，
2)然后将瓶坯加热，再将瓶坯吹塑成型为大输液PP瓶。
与现有技术相比，本发明改变以往焊吊环的方式，在瓶坯未吹塑成型前焊吊环。瓶坯是用注塑模具定型的，形体规范，很容易用设备实现自动化整理，并将其底部顶尖对准吊环中心，另外由于瓶坯的刚性好，吊环焊接的质量有保证。
附图说明
图1为大输液PP瓶未焊吊环的结构示意图，
图2为吊环俯视图，
图3为图2的A-A剖视图，
图4为大输液PP瓶焊上吊环的结构示意图，
图5为瓶坯示意图，
图6为瓶坯焊上吊环的示意图。
图中各标号表示：

具体实施方式
本发明的大输液PP瓶焊接吊环的方法，其工艺步骤为：先将图2、3所示的吊环2焊于未吹塑前的瓶坯3(见图5)底部的顶尖上，成如图6所示，因用注塑模具定型的瓶坯3的形体规范，吊环2中心容易对准其底部的顶尖，另外由于瓶坯3的刚性较好，焊接的质量也好；然后将焊有吊环2的瓶坯3加热，再将瓶坯3吹塑成型为焊有吊环2的大输液PP瓶1，成如图4所示。
