Description

纸质立体袋的烫把机构 技术领域
本发明涉及一种立体袋的烫把机构，尤其涉及到纸质立体袋的烫把机构。
 背景技术
包装袋是用于储存各种用品袋子，使各种用品在生产流通过程中方便运输，容易存储，被广泛用于日常生活中。而无纺布袋具有环保实用的有点，得到大力推广使用，因此促成了无纺布袋制袋机技术快速发展。这种无纺布袋通常由袋体和袋把构成，其袋把是通过超声波焊接装置焊接在袋体上的，这种将袋把焊接在袋体上的机器，就称为烫把机。申请人曾经申请过名称为“烫把机”，公开号为CN109732995A的发明专利申请，公开了如下内容：一种烫把机，包括机架、袋把输送装置、袋把弯折装置、烫把装置和送料装置，其中袋把输送装置将袋把夹持后送到袋把弯折装置上，所述的弯折装置具有一对压把头，在所述压把头的下方设置有与所述压把头相对应的旋转台，所述烫把装置安装在机架上，所述送料装置将需要烫把的布料移送到烫把装置上，其特征在于所述机架上设有将烫把移送到布料处的移动架，所述移动架上设有与所述压把头对应的压头，所述移动架上设有与所述压头对应的支撑平面。这种结构的烫把机，适用于无纺布立体袋。由于无纺布立体袋的袋口折边后，只要在折边处打孔，弯折装置装置将袋把弯折成U型后，通过移动架的移动，便可将U型袋把的两端插入所打的孔内，又由于无纺布具有一定的厚度，其折边打孔后，折边部分与袋体之间具有一定的缝隙，因此，袋把插入后不会受阻。而对于纸质立体袋来说，立体袋的袋口处折边后，其折边部分基本上与袋体的纸张贴合，因此，其采用的方法是将折边部分的纸张予以切割，将需要连接袋把位置折边部分予以割开，虽然割开一部分，但折边部分仍然贴合袋体的纸张，因此，无法将袋把直接插入。
 技术问题
鉴于背景技术存在的不足，本发明要解决的技术问题是提供一种能够将纸质立体袋的袋口折边部分与袋体纸张部分形成一定间隙供袋把插入的纸质立体袋的烫把机构。
 技术解决方案
为此，本发明是采用如下技术方案来实现的：一种纸质立体袋的烫把机构，包括机架、袋把纸卷放置轴、折纸装置、切断装置以及可移动的夹持装置以及袋把弯折装置，所述折纸装置具有一对上下设置的折纸轮，所述切断装置具有刀座和切刀，所述切刀与驱动装置连接，所述弯折装置具有一对压把头，所述压把头的下方设有与所述压把头对应的旋转台，在所述机架上安装有可上下升降的与所述压把头对应的压块，所述压块的下方设有超声波焊接头，其特征在于所述超声波焊接头的上端设置有可移动的插板。
所述折纸轮的袋把进入侧设有压轮与超声波焊把头配合的焊接装置。
所述机架上安装有第一气缸，所述切刀铰接在所述刀座上，所述切刀与所述第一气缸连接。
所述夹持装置具有夹座，所述夹座安装在支架上，所述支架上安装有第二气缸，所述第二气缸的推杆上安装有与所述夹座对应的夹板，所述支架固定连接在同步带上，所述同步带由伺服电机驱动。
所述压块安装在升降架上，所述升降架与安装在所述机架上的第三气缸连接。
所述插板连接在第四气缸的推杆上，所述第四气缸通过连接板安装在所述机架上。
所述超声波焊接头的两端设有可上下移动的压板，所述插板设置在所述两压板之间。
所述压板的端部成弧形设置。
所述压板与第五气缸的推杆连接。
 有益效果
本发明的这种结构，当可移动的插板插入后，便可以将袋口折边部分的纸张与袋体部分的纸张分开，使得弯折装置将袋把弯折后直接插入其分开的空间，具有结构简单，工作快速的特点，特别适用于纸质立体袋的烫把。
 附图说明
下面再结合附图进一步描述本发明的有关细节；
图1为本发明后侧的结构图；
