Product Description

Parallel Return Roller with Bracket: Experience seamless operation with our robust parallel return roller, meticulously engineered to include a sturdy bracket. This component promises consistent performance and outstanding durability, ensuring your conveyor system runs smoothly and efficiently.
The Installation and Debugging Steps of the Idler Set Are as Follows: Ensure optimal performance through precise installation and thorough debugging of our idler set. Follow these essential steps to guarantee peak efficiency and reliability in your conveyor operations.

I. Preparation Before Installation: Laying the groundwork for success, this phase focuses on meticulous preparation to ensure a flawless installation process.
 

1. Check Equipment and Parts: Ensure that every component of the idler set is intact and pristine. Verify that parts such as idlers, brackets, bearings, and seals are complete and undamaged. Inspect the idler surface for smoothness and absence of defects like cracks or depressions to guarantee perfect performance.
2. Prepare Installation Tools: Equip yourself with all necessary tools, including wrenches, screwdrivers, jacks, and spirit levels, to facilitate a smooth and efficient installation process.
3. Determine the Installation Location: Precisely locate the installation site based on the belt conveyor's design requirements. Ensure that the idler set is positioned perpendicularly to the conveyor belt's center line and maintains an ideal spacing in the conveying direction for optimal functionality.

II. Installation Steps: Follow these detailed instructions to seamlessly install the idler set, ensuring secure placement and operational excellence.
 

1. Install the Bracket: Securely fix the idler set's bracket onto the conveyor's frame using bolts or welding. Ensure the bracket's horizontality and verticality are precise for a firm and reliable foundation, employing a spirit level for accurate measurement and adjustment.
2. Install the Idler: Carefully position each idler on the bracket, ensuring correct orientation and placement. Maintain perpendicular alignment of the idler axis to the conveyor belt's running direction, and adhere to design spacing. For trough idler sets, ensure the middle idler is level and the side idlers' inclination angles are accurate.
3. Install Bearings and Seals: Precisely attach bearings to the idler shaft and seal them appropriately to shield against dust, moisture, and impurities. Guarantee the bearings' installation accuracy to prevent excessive tightness or looseness, safeguarding smooth operation.
4. Connect the Transmission Device: If necessary, attach the idler set to a transmission device, such as an electric drum or reducer. Ensure a robust and reliable connection following the transmission device's installation requirements, promoting smooth and efficient power transmission.

III. Debugging Steps: Conduct thorough debugging to ensure flawless operation, identifying and resolving any issues for optimal performance.
 

1. No-Load Debugging: Initiate the belt conveyor and observe the idler set's performance without load. Ensure smooth rotation without jamming or abnormal noise. Confirm the conveyor belt's stable movement on the idler set and address any deviations or bouncing.
2. Adjust the Idler Position: Correct any conveyor belt deviations by adjusting the idler set's position. For parallel idler sets, tweak the idlers' horizontality and verticality. For trough sets, adjust the side idlers' angles until the belt runs true and steady.
3. Load Debugging: After successful no-load debugging, proceed with load testing. Incrementally increase material weight on the conveyor belt, observing the idler set's load-bearing capability and operation. Detect any idler deformation or damage and verify the belt's continued smooth operation, addressing issues promptly.
4. Adjust the Tension: Fine-tune the conveyor belt's tensioning device to achieve optimal tension levels. Avoid excessive tension that increases wear or insufficient tension that compromises stability, ensuring balanced and smooth belt operation.
5. Final Inspection: Conclude with a comprehensive assessment of the idler set. Inspect idler rotation, bearing temperature, and seal integrity. Confirm correct installation and debugging, ensuring the idler set's ability to operate flawlessly.
