Abstract: In order to enhance the triangle groooving holloware tea carding machine, the curve models of Uand obliquetype pot body were established, and on the basis of force analysis and kinematics analysis of the tea in the pots, the movement trajectory and movement law of tea in Uand obliquetype pot body were obtained by MATLAB programming. The result shows, according to the length of the contact between the tea and the bottom of the pot during tea movement, the obliquetype pot has a stronger effect on the tea carding character. This study provides an optimization of structural parameters for triangle groooving holloware tea carding machine.
