一种连续拉伸真空包装机用升降机构
本技术涉及包装机
,尤其涉及一种连续拉伸真空包装机用升降机构。
技术介绍
在连续拉伸真空包装机的热封或成型工位用于推动包材成型模具或热封封口模具升降时均会用到升降机构,目前这种升降机构常采用气缸直推或使用凸轮机构实现模具的升降,这两种方式存在如下缺点:气缸直推存所需气缸缸径大,需要压缩空气多,且空行程及工程行程时速度一样,速度快了冲击大,因此速度不能快,导致生产效率低;而凸轮机构结构复杂,成本高,所需设备空间大。
技术实现思路
鉴于现有技术存在的不足,本技术的目的旨在提供一种结构简单紧凑、运行可靠、需气量少、空程时速度快,在模具之间快接触时,速度线性降低,合模时冲击小的连续拉伸真空包装机用升降机构,为达到以上目的,本技术采用以下技术方案实现:一种连续拉伸真空包装机用升降机构,包括立柱1,所述立柱1下端通过半圆固定环2安装有气缸支板3,所述气缸支板3上铰接有气缸底座4,所述气缸底座4上安装有气缸5,所述气缸5的活塞端与轴二13铰连,所述立柱1中部设有支块7,所述支块7之间设有轴一8,所述立柱1上在支块7下方滑动套设有下轴承座6,所述立柱1上在支块7上方滑动套设有上轴承座15,所述上轴承座15之间设有轴三14,所述轴一8通过下连板9与轴二13铰连,所述轴二13通过上联板12与轴三14铰连,所述轴三14上还设有支撑块11,所述支撑块11通过竖板16与下轴承座6连接,所述立柱1上端还设有滑块10。本技术的有益效果:采用本技术方案的连续拉伸真空包装机用升降机构,通过气缸推动轴二带动上下联板围绕各自轴转动,从而带动支撑块上升或下降, ...
