Bundling device and waste collecting equipment

The utility model discloses a bundling device and waste collecting equipment. The bundling device comprises a conveying mechanism, a rolling and bundling mechanism, a belt tightening mechanism, a detector and a controller. The conveying mechanism is used for conveying a binding belt, the rolling mechanism is used for receiving the binding belt conveyed by the conveying mechanism, the belt tightening mechanism is used for tightening the binding belt at the rolling mechanism, and when the belt tightening mechanism tightens the binding belt at the rolling mechanism, part of the binding belt is pulled out of the rolling mechanism. The detector is used for detecting whether the ribbon exists on the extending path of the ribbon outside the rolling mechanism or not and outputting a stop signal when it is detected that the ribbon exists on the extending path. The controller is electrically connected with the conveying mechanism and the detector, and the controller controls the conveying mechanism to stop conveying th
