Abstract: To quantitatively study the relationship between the needle roller speed and the excess tobacco recycling rate in ZJ17 filter cigarette maker, a linear laser displacement sensor was used to measure the mass of recycled tobacco in the tobacco recycling groove, and the amount of recycled tobacco was obtained by combining the cut tobacco amount of cigarettes. The results showed that: 1) The maximum relative error between the data of the real-time calculated excess tobacco recycling rate method and the weighing method was 3.88%. 2) The real-time measurement problem of the excess tobacco recycling rate was realized by the principle of laser ranging, the excess tobacco recycling rates at different needle roller speeds were investigated, and a quadratic fitting approach was used to obtain the relationship between the needle roller speed and the excess tobacco recycling rate, the fitting results yielded an R² value of 99.5%. 3) By adjusting the machine speed and the maximum speed of the needle roller, quantitative relationships between the machine speed, the maximum needle roller speed and the needle roller speed were derived to facilitate precise control of the needle roller speed and the excess tobacco recycling rate in practical production.
