Abstract

In automated production lines, belt conveyors are essential conveying equipment, and their dynamic characteristics and correction control are critical. By analyzing the structure and working principles of belt conveyors, a corresponding dynamic model is established to explore the dynamic characteristics under various operating conditions, such as vibration and speed fluctuations. The study clarifies how material properties, operating speed, tension force, and other factors influence these dynamic characteristics. Regarding correction control, common causes of deviation, such as installation errors and uneven material distribution, are detailed. Various correction methods, including mechanical, electrical, and intelligent correction, are introduced, along with an analysis of their advantages, disadvantages, and applicable scenarios. This paper aims to provide theoretical support and technical references for enhancing the operational stability, reliability, and conveying efficiency of belt conveyors in automated production lines.
