| The development of tobacco industry in China began in the late 1970 s after the tobacco monopoly system, China’s tobacco industry with more than 20 years of time has introduced a number of advanced foreign technology, machine manufacturing, The introduction and digestion and absorption of foreign advanced technology for the localization of product development path with in minimum cost and the shortest time, leapt to make China’s cigarette machine manufacturing technology abroad in the late 1990.This one of the most typical models have British MOLINS company PASSIM volume unit. The unit has a higher level of electromechanical integration over the same period.Cigarette volume appearance, convenient operation, equipment operation efficiency higher characteristic effectively. But the existence of the unit has been the production of single cigarette box (50000) required more consumption of tobacco, cigarette weight swings, weight standard deviation of the large single cigarette, cigarette higher short rates and other issues since perennial.This design introduces the basic structure and working principle PASSIM machine hopper for wire system, and describes practical application, we found the machine brought frequent downtime problem due to insufficient supply wire, with additions, changes the method of the PLC program problem-solving ideas, and specifically describes the procedures and methods to control feeding time change the program, as well as improved results and significance of cigarette production. |
