The invention discloses a dynamic weighing and sorting integrated device for logistics. The dynamic weighing and sorting integrated device for the logistics comprises a bottom plate, trapezoidal side plates are symmetrically welded to the top end of the bottom plate, the outer sides of first sleeve rolls are sleeved with a feeding conveyer belt in a transmission manner, a protective shell is installed on the portion, corresponding to the corresponding sides of the trapezoidal side plates, of the top end of the bottom plate, a weighing conveyer belt is connected to the outer sides of two second sleeve rolls in a transmission manner, and auxiliary supporting plates are welded to the top ends of fixing vertical plates. The dynamic weighing and sorting integrated device for the logistics is scientific, reasonable and safe and convenient to use; and the feeding conveyer belt, the weighing conveyer belt, the weighing conveyer belt and a sorting carrying plate are smoothly connected through the auxiliary supporting plates, jolting generated through object conveying is reduced, objects can be stably moved in the conveying process, the jamming or jolting and falling condition can not occur, therefore, the purpose of combining feeding, dynamic weighing and logistics sorting together is achieved, a user can conveniently and quickly put, weigh and sort the objects, weighing and sorting integrated operation is achieved, and the device can be used more conveniently.
