In view of the problems of a cigarette factory relocation and technological transformation, which the filter rod conveying system could not meet the filter rod demand of the cigarette making machine and filter rods turnover were inflexible, made a thorough analysis on the system configuration and the production capacity matching calculation, and found that the system configured rod molding machine existed insufficient production capacity. Adding a rod molding machine, adjusting the configuration of equipments in 3 sets of system and modifying related equipments solved the problem of insufficient supply of filter rods and improved the flexibility of filter rods conveying. The measured results show that the system configuration is balanced and reasonable, operates stable and reliable, and all the indicators meet the design requirements. It can meet the production requirements.
