袋式包装动态吸附传送特性的研究

目的基于真空系统理论研究设计一种袋式包装真空吸附传送装置。方法通过建立输送带透气面积和关键结构参数之间的数学模型,探讨装置参数化的设计,并建立动态吸附传送的力学模型,确定其影响因素。结果带速和真空度是动态吸附输送特性的主要影响因素,且真空孔间距d相等时,随着真空孔半径r减小,真空度越容易形成,但真空吸附力也随之变小,不利于吸附输送和开袋。当真空孔半径r相等时,适当减小间距d有利于增加真空吸附力。结论采用合理的真空吸附技术参数供送塑料包装袋有其必要性。

Dynamic Adsorption Conveying Properties of Bag-package

Based on the theory of vacuum system, a vacuum adsorption conveyer of bag-package was designed. The mathematical model between the reasonable area and the key structural parameters was established to study the parameterized design of the device. The mechanical model about dynamical absorption transmission device was established and its influencing factors were determined. The results showed that the belt speed and vacuum degree were the main influencing factors for the dynamic adsorption conveying characteristics. At a constant vacuum hole spacing d, as the vacuum hole radius r reduced, the vacuum degree was easier to form, but the vacuum adsorption force became small, which was not conducive to the adsorption conveying and bag opening. At a constant vacuum hole radius r, a properly reduced spacing d was beneficial to increase the vacuum adsorption force. In conclusion, the use of reasonable technical parameters of vacuum adsorption conveying for plastic bags had its necessity.
