Therefore, an online laser perforating device is designed. By directly performing 360° laser perforation on the surface of the semi-finished cigarette, the stability of the ventilation rate of the cigarette filter can be effectively controlled and the production cost can be reduced. The application results shown that the use of online laser perforation device, by adjusting the perforation time, quantity and size of the hole, the average pass rate of the filter ventilation rate has increased by 17.3%, and the standard deviation pass rate has increased by 10.8%, which effectively improves the stability of ventilation rate for the filter. The average consumption cost of the materials for every 10,000 cigarettes of a certain brand is reduced by 41.2%, which effectively reduces the cost of cigarettes, and can set the different quantity of perforating holes and the filter ventilation rate values according to process requirements. 收起
