颗粒自动包装机主要适用于以下流动性好的颗粒状物料，如农药、兽药、种子、中成药、饲料、咖啡、果品、干燥剂、食盐、味精、汤、茶、洗衣粉、盐、干调味品、白糖、等自由流动颗粒产品。

　　The following introduces the common problems and solutions of the automatic granule packaging machine

　　1. Heat-sealing issues: low-temperature heat-sealing and heat-sealing materials with high thermal adhesive strength should be used. For products with strong pollution such as powders and liquids, heat-sealing materials with good pollution resistance should be selected.

　　2. Friction coefficient problem: The friction force in the packaging process is often both drag force and resistance, so its size should be controlled within an appropriate range. Coiled materials for automatic packaging generally require a small inner layer friction coefficient and a suitable outer layer friction coefficient. If the outer layer friction coefficient is too large, it will cause excessive resistance during the packaging process and cause the material to stretch and deform. If it is too small, it may It will also cause the drag mechanism to slip, resulting in inaccurate tracking and cut-off positioning of the electric eye. However, the friction coefficient of the inner layer is eloquent and cannot be too small. If the friction coefficient of the inner layer of some packaging machines is too small, it will cause the stacking of the bag to be unstable and cause the wrong edge.

3.热封挤出PE问题:在复合膜热封过程中，PE经常被挤出粘在热封膜上，积累越多，就越影响正常生产，挤出的PE在热封模上氧化冒烟，有异味。实践证明，较好的解决方案是采用挤压复合工艺生产复合膜，或提高包装机的速度，使PE不能挤压到热封膜上。
