As shown in fig. 1 and 2, the continuous conveying belt device is connected to an automatic baggage sorting exit of an airport by using a belt conveying mechanism, and specifically comprises a mounting frame 1, a motor 2, a driving roller 3, a driven roller 4, a continuous conveying belt 5 and a photoelectric sensor 6. The motor 2 is installed on the installation frame 1, the continuous conveying belt 5 is sleeved on the driving roller 3 and the driven roller 4 in a rotating mode, the motor 2 drives the driving roller 3 to rotate, and the driving roller 3 drives the driven roller 4 to rotate through the continuous conveying belt 5. Further, the motor 2 can be connected with the driving roller 3 through the driven wheel after the speed of a group of driving wheels and driven wheels is changed, and the conveying speed of the conveying belt is adjusted. The driving roller 3 and the driven roller 4 are both supported by the mounting frame 1, a bearing is mounted on the mounting frame 1, and the driving roller and the driven roller are arranged in the bearing in a penetrating mode. A photoelectric sensor 6 is also arranged at one end of the continuous conveying belt device, which is close to a sorting chute 7 at the outlet of the luggage sorting tray; highly make continuous conveyer belt 5 and 7 high parallel and level of letter sorting spout in luggage letter sorting dish exit through adjusting continuous conveyer belt device, when luggage slides to continuous conveyer belt from letter sorting spout 7 on, thereby photoelectric sensor 6 is sheltered from to luggage makes it take place photoelectric sensing signal, the controller receives starting motor 2 behind the photoelectric sensing signal, make continuous conveyer belt 5 operation certain step, when luggage no longer shelters from photoelectric sensor 6, the motor stops, restart when luggage comes again, so circulation. Further, a photoelectric sensor is also arranged at the tail end (the end far away from the sorting chute 7) of the continuous conveying belt device, and when the tail end photoelectric sensor also senses a shielding signal of the luggage, the continuous conveying belt device does not operate any more.

In general, baggage is sorted out at a sorting center turntable by identifying electronic tag flight information and transported to a main conveyor belt for consigning the baggage on the flight through a sorting center chute; the main conveyor belt transports the luggage to the sorting chute 7 of the designated flight, and then the luggage is manually moved down and placed in a designated area to wait for the loading vehicle of the flight to load the luggage, which not only consumes a large amount of manpower, but also easily damages the luggage. The continuous conveying belt device is added behind the sorting chute of the designated flight, the continuous conveying belt is a lengthened conveying belt, the function of temporarily storing the luggage is achieved, the labor process of manual carrying can be well saved, the luggage is temporarily stored on the continuous conveying belt when the loading vehicle does not come, and the continuous conveying belt device is operated and directly conveyed to the loading vehicle after the loading vehicle arrives.
