【摘要】 针对目前茶叶理条机存在的理条机理条效率低、理条效果差以及理条不稳定等问题,对茶叶颗粒在理条机锅槽内的运动和受力情况开展了研究,提出了茶叶颗粒在锅槽内运动的动力学理论模型,利用ADAMS对茶叶颗粒理条过程进行了模拟仿真试验,分析了茶叶颗粒理条过程中锅槽振动频率、锅槽振幅和锅槽挡板角度对茶叶理条效果的影响,在试验结果基础上对锅槽形状参数和运动参数进行了优化。研究结果表明,锅槽挡板角度对茶叶颗粒沿着锅槽内壁的运动时间有较大影响,锅槽振动频率和振幅对单位周期内摩擦力对茶叶颗粒做功和茶叶颗粒落入锅槽位置有较大影响,参数优化后的茶叶理条机能有效提高理条效率和质量。更多还原

【Abstract】 Aiming at solving the problem of low efficiency and poor quality and instability in tea carding process,the movement and force of the tea particles in hollowware of tea carding machine was studied. The dynamics theory model of the tea particle movement in hollowware was presented. The simulation experiment in tea carding process was carried out based on ADAMS. The influence of vibration frequency,vibration amplitude and the baffle’s angle of hollowware on the effect of tea was analyzed. The shape and motion parameters of hollowware were optimized based on the result of experiment. The results indicate that the angle of the baffle has a great influence on the movement time of the tea along the hollowware,vibration frequency and amplitude of the hollowware have a significant influence on the apply work by friction in a cycle and the position of the tea particle when falling into the hollowware,the tea carding machine can improve the efficiency and quality of tea in tea carding process after parameter optimization.更多还原
