【摘要】：DXDK900四边封条袋包装机是一种采用辊式连续封合的多列小袋自动充填包装设备。它应用广泛，可以将成卷的片膜包材制成四封袋，同时完成对片剂、粉料、颗粒、粘稠及半粘稠液体等不同种类物料的连续充填包装。目前，，由于现有放卷机构中只设有一个工作膜卷，故待包材用完时，存在停机换膜的缺陷，这不但影响了包装机的生产效率和使用寿命，而且也不利于整机的自动化控制。因此，为解决上述问题，本文对如何实现DXDK900四边封条袋包装机的自动换膜进行了研究。首先，本文进行了包材温压特性实验和纵封辊温度曲线的研究，得到了聚酯/铝/聚乙烯复合膜热封参数之间的关系和纵封辊温度的变化及分布情况，为包装机换膜时参数的设置提供了参考。其次，在了解DXDK900四边封条袋包装机工作原理、结构组成及性能特点的基础上，本文对放卷机构进行了改进设计。改进设计的内容包括放卷机构工作原理改进设计、两侧板改进设计、热封装置设计、压紧机构设计和纠偏机构改进设计等，它们为顺利实现包装机的自动换膜奠定了基础。最后，本文进行了热封模具热分析和包材接膜实验，从理论研究与实验分析相结合的角度验证了热封参数设置的合理性。
[Abstract]:DXDK900 Four-sided sealing bag packing Machine is a multi-row bag automatic packing equipment with continuous roller sealing. It can be used widely, and can be made into four sealing bags, and the tablets, powder and particles can be finished at the same time. Continuous packing of different kinds of materials, such as viscous and semi-viscous liquids. At present, because there is only one working film coil in the existing unwinding mechanism, there is a defect of stopping to replace the film when the package is used up. This not only affects the production efficiency and service life of the packaging machine, but also is not conducive to the automatic control of the whole machine. Therefore, in order to solve the above problems, this paper studies how to realize the automatic film change of the DXDK900 four-sided sealing bag packaging machine. Firstly, the temperature and compaction characteristics of the package materials and the temperature curve of the longitudinal sealing roll were studied, and the relationship between the thermal sealing parameters of polyester / aluminum / polyethylene composite film and the change and distribution of the temperature of the longitudinal sealing roll were obtained. It provides a reference for the setting of the parameters when the packaging machine changes the film. Secondly, on the basis of understanding the working principle, structure composition and performance characteristics of DXDK900 four-sided sealing bag packaging machine, this paper improves the design of the unwinding mechanism. The content of the improved design includes the improved design of the working principle of the unwinding mechanism. The improved design of the two sides plates, the design of the heat sealing device, the design of the compaction mechanism and the improvement design of the rectifying mechanism have laid the foundation for the smooth realization of the automatic film changing of the packaging machine. Finally, the thermal analysis of hot sealing die and the experiment of cladding film are carried out in this paper. The rationality of setting parameters of heat seal is verified from the angle of combining theoretical research with experimental analysis.
