摘　　要：带式输送机在片烟装箱翻包中承担烟包输送作用,其输送带在长时间运转后,由于自身粘弹性,产生皮带松动,需液压张紧装置对输送带的张紧度进行调整,以提高输送机运行的安全性。当前液压张紧装置在使用中,存在传感器使用寿命短、信号波动大的问题,影响了输送机运行的稳定性。基于此,优化设计了液压张紧系统,实现了根据实际需求,自动调整带式输送机皮带松紧度。通过现场应用可知,所优化张紧系统满足输送机的实际使用需求,且具有较高的稳定性。The belt conveyor plays the role of empty box conveying in cigarette packing and bag turning.After long-time operation,the belt is loose due to its viscoelasticity.The hydraulic tensioning device is required to adjust the tension of the belt to improve the safety of conveyor operation.At present,there are some problems in the use of hydraulic tensioning device,such as short service life of sensor and large signal fluctuation,which affect the stability of conveyor operation.Based on this,the hydraulic tensioning system is optimized and designed to automatically adjust the belt tightness of the belt conveyor according to the actual demand.The field application shows that the optimized tensioning system meets the actual use needs of the conveyor and has high stability.
