In order to improve the production efficiency of filter rod with embedded flavor capsules, a device incorporating servo control and digital signal processing technologies was developed, it was composed of a control unit, a feeding hopper, an actuating mechanism, and a suction fan. The signal of production speed of filter rod maker was collected by the control unit, the main roller and auxiliary roller in the actuating mechanism were driven by a servo motor for distributing capsules in filter rod, and the filter rods with capsule missing or not properly distributed were rejected. The results showed that the device was good in stability and convenient in operation, the circumference, draw resistance, hardness, roundness of the combined filter rod containing flavor capsules met technical requirements. The capsules in filter rod was uniformly spaced, the filter rods and combined filter rods in which the flavor capsules were not properly positioned accounted for 0.04% and 0.01%, respectively; and none of these two kinds of filter rod was found where the capsule was absent. The batch production of combined filter rod containing flavor capsules was realized, and the production of normal filter rod was not influenced. ©, 2014, Editorial Office of Tobacco Science and Technology.
