Design of negative pressure control system for tipping paper cutting drum in ZJ118 filter cigarette maker.

In order to avoid the breakage and rough cut edge of tipping paper or wrinkled cigarettes caused by the tension fluctuation of tipping paper on the cutting drum in ZJ118 filter cigarette maker during production, a paper tension measuring roller was designed based on the principle of load cell, and force transmission analysis. The negative pressure control system for the cutting drum was developed by combining the BECKHOFF control system, PID adjustment technology and moving average filter algorithm with visual interface technology to realize the automatic adjustment and precise control of the negative pressure in the tipping paper cutting drum. The developed control system was tested on a ZJ118 filter cigarette maker in Xuzhou Cigarette Factory. The results showed that the frequency of tipping paper breakage decreased from 2.1 times/shift to 0.1 times/shift, and that of manual adjustment of negative pressure valves decreased from 0.5 times/shift to 0. The quality score of cigarette making increased from 98.7 to 99.4. This technology provides support for the stability of tipping paper transferring and the promotion of cigarette quality.
