Abstract: Using Creo Parametric tea parametric screening mechanism, the driving model was obtained by behavioral modeling technology, and the coincidence of the axis of the counterweight wheel and the eccentric axis was taken as the objective function, taking into account the processing requirements of the counterweight wheel, and the optimization design of the modification of the counterweight wheel was realized. The design results showed that the product quality is stable, the processing is convenient, and the production cycle of tea color separator is effectively shortened, and the production efficiency of the enterprise is improved.
