Abstract
Provided is an automatic compensation, balancing and tensioning conveying chain wherein the conveying chain can automatically adjust the guide rails to extend and retract and be automatically tensioned and balanced to avoid the influence on the conveying efficiency of the conveying chain due to the slack of the conveying chain. In addition, the guide rail position maintaining components provide a reverse compensation force to the telescopic guide rail when the guide rail pre-warning limiting switches are triggered, so as to reduce the imbalance of movements of the sliding trolleys and avoid a situation that the sliding trolley may trigger an extreme position signal in advance to cause a false alarm and stop the entire conveying chain, thereby guaranteeing a dynamic balance of two tensioning stations and completely eliminating an elasticity change of the chain.
