Abstract

本实用新型公开了一种下开袋机构，包括有支柱，所述支柱上安装有安装座，其特征在于：所述安装座上转动安装有两间隔的主动摆臂和从动摆臂，所述主动摆臂和从动摆臂安装部位分别设有相互对应配合的弧形板，所述弧形板分布有相互啮合的齿，所述主动摆臂和从动摆臂的上端部对应端面上分别设有相互对应的开袋吸盘，所述主动摆臂的下端部与其一侧的气缸活塞杆连接，所述气缸的缸体固定安装在安装座一端的下端面上。本实用新型以气缸作为驱动，以齿轮传动来实现摆臂的张合，以吸盘的真空吸力来完成开袋。该机构结构简单，体积小巧，便于安装，调节调整方便，零件少，成本低，稳定性高。

Description

一种下开袋机构
技术领域
本实用新型涉及包装袋设备领域，尤其涉及一种下开袋机构 。
背景技术
现有的包装袋在包装时，大都是对其上部进行开袋，而底部没有设置开袋结构，从而造成包装袋打开不完成，造成的物料堆积超出袋口的情况出现，影响自动化包装的正常进行。
实用新型内容
本实用新型的目的是为了弥补已有技术的不足，提供了一种下开袋机构，可对平底袋，可对自立型包装袋，M型包装袋，盒式包装袋等预制袋进行下开袋以完成包装袋袋底部分的完全打开，有效防止因包装袋打开不完全，造成的物料堆积超出袋口的情况出现。
本实用新型是通过以下技术方案来实现的：
一种下开袋机构，包括有支柱，所述支柱上安装有安装座，其特征在于：所述安装座上转动安装有两间隔的主动摆臂和从动摆臂，所述主动摆臂和从动摆臂安装部位分别设有相互对应配合的弧形板，所述弧形板分布有相互啮合的齿，所述主动摆臂和从动摆臂的上端部对应端面上分别设有相互对应的开袋吸盘，所述主动摆臂的下端部与其一侧的气缸活塞杆连接，所述气缸的缸体固定安装在安装座一端的下端面上。
工作原理如下：初始状态两开袋吸盘处于分开状态，当包装袋到达两吸盘之间停顿时，气缸杆伸出，带动主动摆臂顺时针旋转，同时主动摆臂上的齿轮带动从动摆臂作逆时针旋转，两摆臂的旋转最终使两开袋吸盘紧贴于包装袋上，并在吸盘中通入的负压作用下牢牢吸住包装袋的两侧；然后气缸开始缩回，使两摆臂分开，将包装袋袋底拉开。
本实用新型的优点是：
本实用新型以气缸作为驱动，以齿轮传动来实现摆臂的张合，以吸盘的真空吸力来完成开袋。该机构结构简单，体积小巧，便于安装，调节调整方便，零件少，成本低，稳定性高。
附图说明
图1 为本实用新型结构示意图。
具体实施方式
参见附图，一种下开袋机构，包括有支柱1，支柱1上安装有安装座2，安装座2上转动安装有两间隔的主动摆臂3和从动摆臂4，主动摆臂3和从动摆臂4安装部位分别设有相互对应配合的弧形板5，弧形板5分布有相互啮合的齿6，主动摆臂3和从动摆臂4的上端部对应端面上分别设有相互对应的开袋吸盘7，主动摆臂3的下端部与其一侧的气缸8的活塞杆连接，气缸8的缸体固定安装在安装座2一端的下端面上。
