Conveyor belts were first introduced to China from abroad. Initially, they were used in the food industry, mainly for steaming instant noodles and in the frying industry. Its material is usually stainless steel, allowing it to come into direct contact with food. The conveying principle of a belt conveyor is that an electric motor drives the drive sprocket and chain, transmitting power to the conveyor belt; through the static friction between the belt and the material, continuous conveying is achieved. It is a type of conveying device that operates in this manner. A belt conveyor is a mechanical device designed for transporting materials in industries such as food, electronics, tobacco, and postal services. The conveyor belt of the belt conveyor can operate in various modes, including normal continuous operation, rhythmic operation, and variable-speed operation. Conveyor belts can also be selected appropriately, with conveyor line configurations such as straight sections, curves, and slopes used to transport materials. A belt conveyor uses a conveyor belt to move in a continuous or intermittent manner in order to transport items weighing up to 100 KG or powdered materials; it features high speed, smooth operation, low noise, and the ability to transport items vertically. In the infrastructure construction module, belt conveyors play a very important role. In the process of some construction projects, its presence can often be seen in sectors such as the steel industry, coal processing, and mining applications. With the continuous improvement of industrial technology, conveyor belt systems have also become more sophisticated, evolving toward greater diversity in their applications, such as long-distance transportation and large-volume transport. In the working module of the belt conveyor, the drums are an important component that is used to withstand alternating stresses. As the working years increase, the surface of the cylinder skin may become worn, which is primarily manifested in cracks and wear on it, as well as in ways to prevent such wear. If proactive maintenance of the drum is not carried out based on the actual conditions, it will affect the proper operation of the conveyor as well as its production capacity. This requires an analysis of the drum’s structure and its stress-bearing components, as well as active improvements to the methods used to assess the drum’s strength, in order to meet the needs of current engineering projects. During the operation of a belt conveyor, its internal components need to be coordinated properly in order to maximize its efficiency. This includes carrying out tasks such as welding the belt and the drum casing, as well as optimizing the connection between the shafts and their attachments, to ensure a proper overall connection between the shafts and the drum equipment. This requires the application of transmission theory and an analysis of the principles of frictional transmission. In the working module of the belt conveyor, the friction between the drive drum and the conveyor belt can serve as a key factor for different working modules, enabling the implementation of energy transfer mechanisms in various devices; this is necessary to ensure the effective operation of the belt conveyor. Affected by the alternating stress caused by the rotation of the drums, belt conveyors may also develop certain problems, such as drum rupture under prolonged exposure to external pressure. To control the drum rupture phenomenon, it is necessary to optimize the working modules of the drum. The most important component of a belt conveyor is the conveyor belt itself, which not only serves to support the material being conveyed but also transmits the pulling force from the power source. Producing high-quality conveyor belts is crucial for belt conveyors.
