Objective: To reduce the rejection rate of ZJ17 cigarette machine, shorten the adjustment time and improve the production efficiency. Methods: The rubber roller phase alignment device was developed to accurately measure the position of the rubber line by the sensor, and the measurement signal was transmitted to the industrial computer in real time. The shaft encoder signal was used to judge the offset of the rubber line, and the servo motor was driven to automatically adjust the phase of the rubber roll, so as to realize the real-time control of the position of the rubber line. Results: The rubber roller phase alignment device was easy to install and easy to maintain. The debugging time of the equipment was significantly shortened, and the debugging smoke branches are reduced from more than 30 000 before the transformation to within 1 000. Conclusion: The application of rubber roller phase alignment device improves production efficiency, and the cost reduction and efficiency are significantly effective.
