The Application of Variable Frequency Technology in Modification PROTOS Cigarette Making Machine

The waste rate of PROTOS80 in actual production is higher than the internal controlled target. The analysis data shows that it is due to the abrasion of the parts in needle roller driving system. The abrasion will lower the precision of the driving system, and make it hard to keep the setting speed. This will cause unstable weight of cigarettes, more empty or block tobacco while start or stop the machine, which means higher waste rate. This can be solved by using AC variable frequency speed control system in needle roller driving system and modify relevant devices. It will greatly improve the accuracy and stability of the system; furthermore, easy maintenance. The solution can be promoted to other PROTOS series machine valuably.
