How to check and adjust the belt tension on the SGBELT conveyor

The belt tension is set at the end of the manufacturing process of each conveyor. Once you receive the conveyor, it will not require belt calibration.

Over time, the tension of the belts may decrease minimally. For this reason, we recommend checking the tension of the conveyor belts every 12 months.

To make this process faster and more accurate, the conveyor set includes a voltage measuring kit that we will use for this purpose. Consisting of two disc and an indicator, it will allow you to check the tension of the conveyor belts in less than 5 minutes.

To begin with, unplug all cables connected to the USB ports and the power supply from the conveyor. Prepare a 2 mm Allen key. Turn the conveyor so that its back is facing you and remote two middle slots from the bottom of the conveyor. If you have W60 wide sockets installed, just remove one socket. Slide the socket mounting beam so that there is enough space to insert the disc. It should be inserted obliquely under the straps and then rotated so that it wedges into the conveyor housing. Make sure the disc is evenly wedged against the housing. Incorrect engagement of the disc will result in an incorrect reading of the belt tension. Make sure that the inscriptions of the dial are directed towards the left side of the conveyor. Now we can put the socket mounting beam back on the strip marker and then mount the pointer to it with screws, making sure that the blue markers are facing the left side of the conveyor. Attach the pointer using the screws that were used to attach the socket.

Turn the conveyor so that it stands on attached legs and place it on a level surface. Check that it is horizontally positioned. To do so, use the spirit level from the kit by placing it on the top surface of any conveyor slot. Looking from the bottom of the conveyor belt, you will see the inscriptions on the dial. Check that the height indicator overlaps the marked blue space between the maximum and minimum height levels. If so, the belt tension is correct and does not need to be changed.

If the pointer extends beyond the blue area of the dial, the strap tension must be adjusted. Unscrew one or two of the end plates on the left side of the conveyor. This will reveal 4 Allen screws to adjust the tension of the straps. Prepare a 4mm Allen key needed to change the tension of the straps. Tightening or loosening the screws in pairs on the left or right side by the same angle, you can tighten or loosen the conveyor belts. The desired outcome is have pointer to indicate an equal level on both sides of the disc, what means that the tension of both belts is equal.

The correct belt tension in the conveyor reduces the excessive wear of the conveyor components. After verifying their tension or changing them – in the order opposite to one observed during the assembly, unscrew the pointer from the mounting beam and remove the disc from under the conveyor straps. At the very end, make sure that the mounting beams are positioned in the places marked on the straps and screw in any missing conveyor slots, paying attention to their orientation relative to the rest of the slots.

For the service work where it is necessary to remove the drive belts completely, you can simply re-tighten the belts to the recommended value using this manual.
