In response to the problem of unsatisfactory strip formation due to the unknown mechanism of tea strip kinetics in the green tea processing and strip-forming compound process, the continuous collision law between tea leaves and pot trough in the pot trough of continuous compound barber was studied, the kinetic model of rolling, throwing and collision of tea leaves in the pot trough in three stages was established, and the barring mechanism of continuous compound tea barber was determined. According to the law of forming the movement of tea leaves in the pot trough, the inclined U-shaped pot trough was optimized, and the simulation model of tea-leaf-pot trough interaction under thermosolid coupling was established by Rocky Dem, by analyzing the average velocity and force of tea leaves, the optimal working parameters of pot trough reciprocating motion velocity, angle of pot trough baffle and angle between pot trough and horizontal surface were determined. On the basis of the optimal parameters, a three-factor, three-level orthogonal test was conducted to determine the optimal combination of parameters under actual working conditions. The test results showed that when the angle of the pot baffle was 114.1°, the reciprocating motion velocity of the pot was 190.9r/min, and the angle between the pot and the horizontal surface was 3.2°, the strip formation rate was 85.89% and the broken tea rate was 1.70%, which satisfied the agronomic requirements of strip management. The validation tests showed that with this optimal combination of structure and operating parameters, the rate of forming and breaking tea was 84.26% and 1.79%, respectively, with the relative error within 5% from the optimized results, indicating the reliability and accuracy of the optimized results. The research result can provide a reference for the optimization of the key parameters of tea barring and forming mechanism and barring machine.
