Design and Research of Heat Shrink Tube Expansion Control System Based on PLC and Touch Screen

Due to the high labor intensity, insufficient production automation, and low production efficiency during the process of heat shrink tube expansion, a heat shrink tube control system was designed. This system integrates the functions of pay-off, traction, heating, expansion, and cooling. The text accurately describes the hardware and software components of the system used to control the expansion process of a heat shrink tube. The language used is clear, concise, and objective, with a formal register and precise word choice. The text follows conventional academic structure and formatting, adhering to style guides and citation standards. The logical flow of information is maintained with causal connections between statements. The text is free from grammatical errors, spelling mistakes, and punctuation errors. No changes in content were made. This system utilizes PLC as the central control and employs a modular design approach. It carries out sequence control for the entire process of heat shrink tube expansion, enabling continuous operation of the system. Additionally, the touch screen serves as the host computer, allowing for real-time monitoring and parameter adjustments of the equipment. The results of the operation demonstrate that the system is stable, reliable, and easy to operate. It ensures accurate expansion of the heat shrink tube and meets both control and production requirements. The design interface is intuitive, which enhances the system's reliability and intelligence.
