摘要
针对当前国内茶叶杀青理条机存在噪声大、振动磨损大、温度不稳定、自动化程度不高等问题,对茶叶杀青理条机送料装置、杀青理条装置进行优化设计,将其作为2个独立机构布置,采用电动缸提升多槽锅,消除振动对称量精度的影响,运用SolidWorks软件建立茶叶杀青理条机三维模型;对温控系统进行优化设计,采用模糊PID对茶叶杀青理条温度进行控制,利用Matlab/Simulink软件对温度控制系统进行仿真分析.研制茶叶杀青理条机样机,对比试验结果表明,设计增强了温控系统抗干扰能力,茶叶成条率、处理效率分别提高7.6％,28.0％,含水率、碎茶率、噪声、轴承温升分别降低7.9％,25.0％,23.1％,46.2％.研究为茶叶杀青理条机的设计提供理论依据.
Abstract
In response to the problems of high noise,high vibration and wear,unstable temperature,and low degree of automation in the current domestic tea fixing and carding machine,the feeding device and fixing and carding device of the tea fixing and carding machine were optimized and designed as two independent mechanisms.Electric cylinders were used to lift multi-slot pots and eliminate the influence of vibration symmetry accuracy.Solidworks software was used to establish a three-dimensional model of the tea fixing and carding machine;The temperature control system was optimized,fuzzy PID was adopted to control the temperature of tea leaves for fixing and carding,and Matlab/Simulink software was used to simulate and analyze the temperature control system. A prototype of a tea fixing and carding machine was developed,and the comparative test results show that the design enhances the anti-interference ability of the temperature control system.The tea forming rate and processing efficiency are increased by 7.6％ and 28.0％,respectively.The moisture content,broken tea rate,noise,and bearing temperature rise are reduced by 7.9％,25.0％,23.1％,and 46.2％,respectively.The study provides a theoretical basis for the design of tea fixing and carding machine.
