Abstract:Firstly the mechanism of overturning ceramic tiles of the overturning device of ceramic tile packaging machine was studied. Then, the change of the velocity, the acceleration of ceramic tiles and the effect of impact force on the quality of ceramic tiles were discussed. The influence of the frequent changes in pulling strength of conveyor belt on working stability was analyzed. In the end, the improvement on the overturning device of ceramic tile packaging machine was designed according to the requirements of tile working conditions.
