The roller conveyor production line is the core equipment of conveying systems in industrial production, and its normal operation directly affects both production efficiency and product quality. Below are the comprehensive maintenance contents and methods for roller conveyor production line equipment: 
I. Basic Maintenance Items  
Regular cleaning: 
Clean the surface of the idler rollers and around the bearing housings to remove dust and debris, preventing bearing blockage or accelerating surface wear. 
Use tools such as a clean soft cloth, brush, or compressed air for cleaning. 
For hard-to-clean areas, use specialized cleaning tools or detergents (avoid using corrosive cleaners such as strong acids or strong bases).

Check for wear: 
Regularly inspect the roller shell, sealing rings, and bearings for wear. 
If the casing is deformed, the sealing ring is damaged, or the bearing makes unusual noises during rotation, address the issue promptly. 
When the wear exceeds one-third of the original thickness, replacement should be considered. 
Lubrication Maintenance: 
Lubricate the bearings with the appropriate grease (such as lithium-based grease) at the prescribed intervals. 
Ensure the bearings are well-lubricated to minimize frictional losses. 
The amount of lubricant should be 1/3 to 1/2 of the bearing chamber, avoiding both excess and insufficient amounts. 
Replace the damaged components: 
When rollers are found to be jammed, rotating inflexibly, or severely damaged, immediately replace them with new ones. 
Replace rollers that produce abnormal noises or fail to rotate promptly. 
Environmental Protection: 
In humid, corrosive environments, choose corrosion-resistant idlers. 
Strengthen protective measures to prevent roller rusting. 
II. Maintenance Methods for Main Components 
1. Roller Maintenance 
Cleaning: Inspect the roller surfaces daily, removing dust, dirt, and debris, especially any residual material being conveyed. 
Lubrication: Select the appropriate lubricant based on the roller type and working environment, and perform lubrication according to the specified cycle and method. 
Check: Regularly inspect the roller bearings for rotational flexibility, ensure the seals are intact, and examine the surface for any signs of wear. 
Replacement: The labyrinth seal should use genuine factory parts, and during assembly, each seal must be inserted individually into the roller—never fitted together as a set. 
2. Conveyor Belt Maintenance 
Avoid letting the rollers become covered with material, which could lead to sluggish rotation. 
Prevent material from getting stuck between the roller and the conveyor belt 
Ensure proper lubrication of the moving parts, but avoid oiling the conveyor belt. 
If the tape deviates from its intended path, measures should be taken promptly to correct it. 
Discover any localized damage to the tape and repair it promptly to prevent it from spreading. 
Avoid tape from being blocked by racks, supports, or bulky materials, preventing it from tearing or ripping. 
3. Drive System Maintenance 
Cleaning and Dust Prevention: Regularly clean the servo motor driver, ensuring the surfaces of the housing and radiator remain free of dirt and dust. 
Check the power supply and cables: Ensure the power is stable, and inspect the connection cable between the drive and the servo motor. 
Maintain proper heat dissipation: Ensure good ventilation and regularly check that the radiator is clean. 
Check and calibrate parameters: Regularly inspect the parameter settings of the servo motor driver to ensure that parameters such as speed and acceleration are correctly configured. 
III. Maintenance Precautions 
Installation accuracy: 
Ensure that the axis of the idler roller is perpendicular to the centerline of the conveyor, with any deviation kept within ±2°. 
Set the roller spacing strictly according to the design requirements. 
Avoid overload: 
Operate strictly within the rated load capacity and avoid overloading. 
The single-roller load capacity of standard polymer rollers ranges from 2 to 5 tons, while heavy-duty rollers can handle up to 8 to 12 tons. 
Prevent foreign objects from entering: 
Prevent sharp objects such as wire and stones from entering between the idler roller and the belt. 
Avoid scratching the roller surface, which could compromise its smoothness and finish. 
Avoid frequent start-and-stop operations: 
Minimize the frequency of the conveyor's start-and-stop operations. 
Frequent starts and stops subject the idler rollers to significant impact loads, accelerating wear on both bearings and seals. 
Temperature Control: 
The ambient temperature should generally be maintained between -20°C and 60°C. 
Too low a temperature may cause the material to become brittle, while too high a temperature could affect dimensional stability. 
IV. Safety Regulations 
Operational Safety: 
Equipment maintenance and upkeep must be performed by professional technicians. 
When performing equipment maintenance and upkeep, it is essential to disconnect the power and shut down the transmission parts. 
Inspection System: 
Adhere to the巡回 inspection system and conduct inspections on schedule. 
Immediately replace any idlers that make unusual noises or fail to rotate. 
Protective measures: 
When using the idler roller, strictly prevent heavy objects from striking or impacting the roller tube. 
To ensure the sealing and performance of conveyor rollers, disassembling them at will is strictly prohibited. 
Special Environment: 
Polymer rollers used in underground coal mines must undergo rigorous explosion-proof certification. 
Ensure that the idlers have excellent antistatic performance. 
By implementing the comprehensive maintenance measures outlined above, you can significantly extend the service life of the roller conveyor production line, enhance equipment operational efficiency, minimize downtime due to failures, and ensure the stable operation of the production line. It is recommended that companies develop detailed maintenance plans and inspection protocols tailored to their specific equipment usage and production environments.
