I. Introduction
The conveyor is one of the indispensable and important equipment in industrial production, and the roller is one of the core components of the conveyor. The role of the roller is to support the conveyor belt or chain, allowing the material to be transported smoothly on its surface. Different types of rollers have different characteristics and applicable occasions, so it is very important to understand the different types of rollers and their characteristics for the correct selection and use of rollers. This article will give you a detailed introduction to the different types of rollers for conveyors and help you choose the most suitable roller for you.
1. Drive the drum
The drive pulley is one of the most critical pulleys in a conveyor, and it is responsible for providing power to keep the conveyor belt or chain running. The outer surface of the drive drum is usually made of wear-resistant, corrosion-resistant materials, such as stainless steel, polyester composites, etc. The design of the drive pulley should consider factors such as power, speed, sealing, etc., to ensure that it can safely and stably drive the conveyor belt or chain.
2. Idler pulley
Idler pulleys are often used to change the direction of a belt or to increase belt tension. Idler pulleys rotate at a lower speed and do not provide power than drive pulleys. The outer surface of the idler pulley is usually made of wear-resistant, corrosion-resistant materials, such as polyester composites, rubber, etc. The idler pulley should be designed with its support capacity and sealing performance in mind to ensure that it can operate stably and provide sufficient tension force.
3 Reversing the drum
The reversing roller is mainly used to change the running direction of the conveyor belt, and is usually set at the beginning and end of the conveyor belt. The outer surface of the reversing drum is usually made of wear-resistant, corrosion-resistant materials, such as stainless steel, polyester composites, etc. The design of the reversing drum should take into account its support capacity and sealing performance to ensure that it can operate stably and provide sufficient tension force.
4. Tension the drum
The tensioning roller is mainly used to adjust the tension of the conveyor belt, and is usually set at the beginning and end of the conveyor belt. The outer surface of the tensioning drum is usually made of abrasion-resistant, corrosion-resistant materials such as rubber. The design of the tension drum should take into account its adjustment range and support capacity to ensure that it can provide sufficient tension and operate stably.
5. Idler roller
Idler rollers are mainly used to support conveyor belts or chains, preventing them from sagging or stuck. Idler rollers are usually located on the upper and lower sides of the conveyor belt, and can be used in different lengths and diameters as needed. The outer surface of the roller drum is usually made of wear-resistant, corrosion-resistant materials, such as stainless steel, polyester composites, etc. The design of the idler drum should consider its supporting capacity and sealing performance to ensure that it can operate stably and provide sufficient support force.
3. How to choose the most suitable roller
1. Select the type of drum according to the use occasion
Different types of rollers are suitable for different occasions. For example, drive rollers are suitable for applications where power is required; The idler pulley is suitable for changing the running direction of the conveyor belt; The reversing roller is suitable for occasions that need to change the running direction of the conveyor belt; The tensioning roller is suitable for occasions where the tension of the conveyor belt needs to be adjusted; Idler rollers are suitable for applications where a conveyor belt or chain needs to be supported. Therefore, when choosing a drum, you should choose a suitable type of drum according to the actual use needs.
2. Select the drum material according to the type of conveyor belt
Different types of conveyor belts have different requirements for the drum material. For example, when the conveyor belt is a steel wire rope core, polyester composite material or stainless steel with good wear resistance should be selected as the drum material; When the conveyor belt is canvas, rubber should be selected as the drum material. Therefore, when selecting a pulley, the appropriate pulley material should be selected according to the type of actual conveyor belt.
3. Select the drum size according to the conveyor power
The power of the conveyor is different, and the requirements for the size of the drum are also different. In general, the more powerful the conveyor, the larger the diameter of the pulley to withstand the larger the load. Therefore, when selecting a drum, you should choose a suitable drum size according to the actual power of the conveyor.
4. Consider environmental protection and energy saving factors
With the continuous improvement of environmental protection and energy saving awareness, more and more enterprises have begun to pay attention to the application of environmental protection and energy saving factors in production equipment. Therefore, when choosing a drum, the use of environmentally friendly and energy-saving materials and designs should be considered, such as the use of low-energy motors and control systems.
