The prompt
Fix the mounting of the lower return rollers. Each lower roller must be securely supported by the conveyor frame using mounting brackets or axle supports attached to the side rails. Both ends of each roller axle must be properly supported and connected to the frame. The rollers must remain free to rotate. **Do not change anything else.** Keep the existing conveyor dimensions, frame, belt, drums, motor, gearbox, and all other components exactly as they are.
