Belt conveyor speed stabilization system based on load changes

Abstract

1. Actual demand: Today, society is developing, along with the industrialization and modernization of the country, many industries serve the country's industrial development process. Such as mining minerals, and transporting materials and goods in factories and enterprises, the field of automatic control has helped people solve the above problems more easily and with higher productivity. Therefore, the birth of the pruning system was inevitable The system of stabilizing the conveyor speed when the load changes is that when we set the belt conveyor speed well to suit the working line, the load applied changes and the speed will still not change. Depending on different materials and goods, each speed will be different. The above system is often used for transporting goods for packaging, transporting materials to boilers, incinerators, etc… 2. Scope of research topic ­ Research and design a system to stabilize conveyor speed. ­ Research and apply PLC programming for automatic control systems. ­ Applying the knowledge learned and learned outside to the design and manufacture of the system. ­ Research and apply mechanical, electrical, and design software to design and manufacture models with practical applicability. ­ Build a system can allow the selection of parameters according to practical requirements with the accuracy allowed. 3. The content of the topic has been done ­ Number of drawings: 4 ­ Thesis: 1 4.
