Solution Approach 1:

The patent replaces the traditional chain-operated mechanical system with a pneumatic system that uses air pressure to actuate the belt tracking and tensioning mechanisms. This substitution eliminates the mechanical contact and friction that generate excessive noise, while maintaining the functional capability of tracking and tensioning the belt in curved sections.

Inventive Principle:

Solution Approach 1:

The patent employs dynamically adjustable tracking mechanisms that can adapt their configuration based on the conveyor section geometry. In straight sections, the mechanisms maintain stable belt alignment, while in curved sections, they adjust to accommodate the curved motion, ensuring proper belt tracking throughout the entire conveyor system.

Inventive Principle:

Solution Approach 2:

The invention utilizes adjustable parameters of the tracking mechanism, such as roller positions and angles, to adapt to different conveyor section geometries. By changing these parameters dynamically, the system maintains effective belt tracking in both straight and curved sections without compromising alignment stability.
