Description
技术领域 technical field
本发明涉及一种包装机，具体涉及一种收缩膜包装机。 The invention relates to a packaging machine, in particular to a shrink film packaging machine.
背景技术 Background technique
收缩膜包装机用于卷筒墙纸、广告纸、礼品纸及其它物料等的热收缩膜包装。目前，要实现卷筒纸等物料全自动热收缩膜包装的设备只有国内外极少数的几家公司在生产，其结构复杂成本高。为解决上述问题，本公司开发了一种结构简单合理的全自动卷筒墙纸包装机产品，并于2011年12月30日申请了国内实用新型和发明专利，发明专利申请号201110461546.3，名称《全自动卷筒墙纸包装机》。但是，上述开发的产品只具备对收缩膜进行横向封切的功能，收缩膜在烘箱内进行热收缩后，物料的两端会留有透孔，虽然这样的包装具有好的透气性，但显然不能满足包装密封性要求（以前只要求包装的透气性，在密封性方面基本没有要求，近年来才越来越重视），在潮湿环境下不能长期保证质量。 Shrink film packaging machine is used for heat shrink film packaging of roll wallpaper, advertising paper, gift paper and other materials. At present, only a few companies at home and abroad are producing equipment for fully automatic heat-shrinkable film packaging of materials such as roll paper, and its structure is complex and costly. In order to solve the above problems, our company has developed a fully automatic roll wallpaper packaging machine with a simple and reasonable structure, and applied for a domestic utility model and invention patent on December 30, 2011. The invention patent application number is 201110461546.3, and the name is Automatic roll wallpaper packing machine". However, the products developed above only have the function of laterally sealing and cutting the shrink film. After the shrink film is heat-shrunk in the oven, there will be holes at both ends of the material. Although such packaging has good air permeability, it obviously cannot Meet the requirements of packaging tightness (in the past, only the air permeability of the packaging was required, and there was basically no requirement for sealing, and more and more attention has been paid to it in recent years), and the quality cannot be guaranteed for a long time in a humid environment.
