基于PLC的茶叶揉捻机压力动态调节方法研究*

传统茶叶揉捻机在工作时,茶叶在揉捻桶内不停翻滚,导致茶叶受到的压力忽大忽小,变化剧烈,对压力无法量化和精准控制,针对以上问题,提出了一种揉捻压力实时动态调节的控制方法,对控制系统的硬件、算法和程序进行了详细的阐述,该系统能将压力值量化,确保了揉捻压力控制的动态调节、实时性和精准控制,试验表明,加装了该系统的茶叶揉捻机在成条率、碎茶率和生产效率方面均达到了行业标准要求。

Research on dynamic pressure adjustment method for tea rolling machine based on PLC

During the operation of traditional tea twisting machines, the tea leaves continuously twist in the twisting barrel, causing the pressure on the tea to fluctuate greatly and violently, making it difficult to quantify and accurately control the pressure. In response to the above problems, a real-time dynamic adjustment control method for twisting pressure is proposed, and the hardware, algorithm, and program of the control system are elaborated in detail. The system can quantify the pressure value, The dynamic adjustment, real-time performance, and precise control of the rolling pressure control have been ensured. Experiments have shown that the tea rolling machine equipped with this system meets industry standard requirements in terms of sliver formation rate, broken tea rate, and production efficiency.
