Objective An aerosol filling online swinging technology was put forward and implemented. Methods Through the analysis of aerosol filling processes, combined with the characteristics of the production line, an online modified alternative was given. Firstly, the structural implementation of online swinging device was analyzed in detail, and the working principle was explored simultaneously. Then the control system option was presented. Results It was shown that the online swinging device of aerosol filling could realize the operation of aerosol products with different number, different frequency and amplitude, which was reliable in operation and showed full uniformity and stability in swinging. Conclusion A feasible scheme was provided for realizing online swinging of aerosol filling, and at the same time, the upgrade in automation of aerosol filling line was promoted.
