The invention discloses a telescopic belt type weight-volume measuring and code-scanning intelligent all-in-one machine. The telescopic belt type weight-volume measuring and code-scanning intelligent all-in-one machine comprises a telescopic type belt conveyor, and further comprises a weighing mechanism, a volume measuring mechanism, a code-scanning mechanism, a PLC programmable controller and a PC server, wherein a towing-speed section conveyor belt, a weighing section conveyor belt and a quick separating section conveyor belt are sequentially arranged at one side of the telescopic type belt conveyor; the weighing mechanism is used for obtaining weight information of goods; the volume measuring mechanism is used for obtaining volume information of the goods; the code-scanning mechanism is used for obtaining bar code/two-dimensional code information of the goods; the PLC programmable controller is used for controlling the telescopic type belt conveyor, the towing-speed section belt conveyor, the weighing section conveyor belt, the quick separating section conveyor belt, the weighing mechanism, the volume measuring mechanism and the code-scanning mechanism to cooperatively work; and the PC server is used for receiving and uploading weight, volume, bar code and two-dimensional code information of the goods. On the basis of having a goods conveying function, the telescopic belt type weight-volume measuring and scanning intelligent all-in-one machine further has the functions of automatically acquiring and uploading goods weight, volume, bar code/two-dimensional basic information, and has the advantage of being time-saving and efficient.
