[0038] As an example, one or more of the conveyor belts may be configured as follows: Figure 3 The geared motor transmission structure shown.

[0039] As an example, the angler in this embodiment can be designed as follows:

[0040] like Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 The structure of the angler itself is roughly illustrated. A slider 8Ⅱ is set on the angler body 8Ⅰ, and the slider 8Ⅱ cooperates with the slide groove Ⅰ1 set on the conveyor side plate Ⅰ. The angler body 8Ⅰ can move up and down along the slide groove Ⅰ1 under the drive of the angler up and down driving reduction motor Ⅱ. The angler up and down driving reduction motor Ⅱ is fixed on the conveyor side plate Ⅰ. The output shaft of the angler up and down driving reduction motor Ⅱ is connected to the gear Ⅲ, and the gear Ⅲ cooperates with the rack fixed on the angler body 8Ⅰ; the surface of the angler body 8Ⅰ that contacts the luggage is an arc surface, and a plurality of rotatable rollers 8Ⅲ are set on the surface. The rotating rollers 8Ⅲ are connected to the gears through the axles. 8Ⅳ is driven, with wheels at both ends of the axle 8Ⅳ and an axle in the middle, which is rotatably fixed below the angler body 8Ⅰ. When the angler is at the bottom, the wheels of the axle 8Ⅳ are in contact with the conveyor belt. As the conveyor belt moves forward, the wheels rotate accordingly. The axle 8Ⅳ and the rotating roller 8Ⅲ transmit the rotation of the axle 8Ⅳ to the rotation of the rotating roller 8Ⅲ through the cooperation of the worm gear. The cooperation of the worm gear should satisfy the rotation direction of the rotating roller 8Ⅲ so that the luggage will move forward when in contact with the rotating roller 8Ⅲ. The conveyor belt is used to indirectly drive the rotating roller 8Ⅲ, eliminating the need to add a driving motor to drive the rotating roller 8Ⅲ.
