Conveyor belt unit with configuration-changing mechanism

A conveyor belt unit for conveying an object over a dynamic checkweigher, comprising:

• a carrier frame;
• a belt body, connected to the carrier frame for conveying the object, comprising:
• a pair of rollers, one arranged at an end of the belt body in a transport direction and one arranged at an end contrary to the transport direction;
• and
• a conveyor belt tensioned across the pair of rollers;
• a motor arranged to drive the conveyor belt by means of one of the rollers;
• and
• a configuration-changing mechanism, effective between the belt body and the carrier frame to switch the conveyor belt unit between a not-ready-to-operate configuration and a ready-to-operate configuration, when the configuration-changing mechanism is actuated, the configuration-changing mechanism comprising at least one rotating joint element having a thin material bridge that defines a rotary axis thereof.
