Abstract: [Objective] To further reduce labor costs, solve problems such as easy tearing of fruit labels, time-consuming and laborious manual labeling, and resource waste, and use PLC technology to improve the efficiency and quality of fruit labeling. [Method] The research group used mathematical dynamics models to propose a fruit pneumatic marking machine based on PLC, and analyzed and designed the pneumatic system and control system of the fruit pneumatic marking machine. The hardware part of the control system is designed with module selection of PLC controller and operating parameters of each execution module. The software part is designed with internal I/O address allocation of PLC and ladder diagram compilation. [Result] A simulation experiment was conducted on a fruit peel using a pneumatic marking machine. The marking speed was fast, the pulp was intact and not damaged, and the work efficiency and quality were significantly higher than those of manual labor. [Conclusion] The pneumatic marking machine based on PLC control has the advantages of both pneumatic technology and PLC technology. The working medium is economical and easy to obtain, environmentally friendly and pollution-free, and has good controllability. It can achieve automatic feeding and rapid printing of fruit agricultural products through PLC programs. It can be used in harsh environments and on assembly lines with fast speed requirements, and has promotional value.
