| Abstract: |
| The work aims to improve the main performance indicators of the corrugator to meet the requirements of high-efficiency and high-quality corrugated forming. After the affecting factors of corrugated board forming quality and the characteristics of the existing corrugator transmission system were studied, the high-rigidity structure and control scheme of differential gear transmission that could suppress vibration were proposed aiming at effect of the rigidity of the transmission system on its performance. Then, simulation research was carried out and experimental verification was conducted by improving the transmission system structure of existing model. The angular velocity and angular acceleration curves of the corrugated roll before and after the optimization were obtained. It was found that the angular velocity fluctuation range was from 75-225 deg/s to 100-150 deg/s, and the angular acceleration fluctuation range was from ‒740-370 deg/s2 to ‒100-110 deg/s2. According to the experimental measurement results, the difference in the extreme thickness of corrugated board decreased from 0.23 mm to 0.09 mm, and the noise was reduced by 4%-15.2% on year-on-year basis. Therefore, the differential gear transmission scheme is feasible, which provides new ideas and technical support for improving the rigidity of the corrugator transmission system and the quality of corrugated forming. |
