Application and Improvement of Vacuum Aluminizing Inner Liner in FOCKE703 Packer

Vacuum aluminizing inner liner is of high resilience and thin aluminum coating,it tends to be creased during folding in FOCKE703 packer.By analyzing the makeup of the inner liner conveying system and the factors influencing the packing quality of cigarette packets,the related folding parts and electric elements were improved as following:1) regulating the pressure of embossing roller to reduce the resilience of folded inner liner;2) modifying the inner liner short slit knife to prevent pull piece from dropping;3) improving electric detection elements to keep the lateral deviation of inner liner within acceptable limits.The results of application showed that the average number of cigarette packets with the defects of inner liner folding decreased from 165 to 28 packet/shift,while machine efficiency increased from 78.3% to 84.2%,the number of machine stoppage reduced obviously.The stability and reliability of vacuum aluminizing inner liner in packing process were effectively improved.
