[0055] Preferably, the driving assembly 140 further comprises a support plate 153 fixedly connected with the movable frame 142, and the compression shaft 146 and the driving shaft 144 are both inserted with the support plate 153, that is, the limiting part is connected with the movable frame 142 through the support plate 153, and the overall structure of the driving assembly 140 is more stable by arranging the support plate 153. Specifically, the support plate 153 is provided with a first hole 154 corresponding to the driving shaft 144 and a second hole 155 corresponding to the compression shaft 146, after the compression wheels 147 on the two compression shafts 146 compress the conveying belt 130 on the driving wheel 143, the end portions of the two compression shafts 146 are inserted with the guide groove 121 and pass through the guide groove 121, and then the support plate 153 is installed, so that the first hole 154 and the second hole 155 on the support plate 153 are respectively sleeved on the driving shaft 144 and the compression shaft 146, and then the movable frame 142 is fixedly connected with the movable frame 142 by using screws or other fasteners.

When the conveying belt 130 is a toothed belt, the "rolling fit" means that the driving wheel 143 and the conveying belt 130 are in meshing transmission to drive the conveying belt 130 to move.

[0059] The number of the compression shafts 146 is not limited.

In this embodiment, the axis of the transmission shaft 150 is perpendicular to the axis of the driving shaft 144.

[0064] Preferably, referring to Figure 6 As shown, the driving assembly 140 further comprises a transmission wheel 149, and the transmission wheel 149 is fixedly sleeved on the driving shaft 144.

[0067] The passive rotation mode of the input wheel 141 is not limited, for example, in the embodiment, the input wheel 141 can roll along the rack 11. Specifically, two friction surfaces are provided on the rack 11, the two friction surfaces are respectively a first friction surface 111 and a second friction surface 113, and the two friction surfaces extend along the moving direction of the sorting trolley 12. When the sorting trolley 12 moves, the input wheel 141 of the driving assembly 140 located at the first position can roll with the first friction surface 111, the input wheel 141 is driven to rotate forward, and the input wheel 141 of the driving assembly 140 located at the second position can roll with the second friction surface 113, the input wheel 141 is driven to rotate reversely. Here, "roll with" means that the first friction surface 111 and the second friction surface 113 are fixedly arranged, and the input wheel 141 rolls along the first friction surface 111 or the second friction surface 113. In other embodiments, the input wheel 141 is a gear, and the walking wheels at both ends of the sorting trolley 12 are coaxially fixedly connected with transmission gears. When the driving assembly 140 is located at the first position, the input wheel 141 meshes with the transmission gear at the first end of the sorting trolley 12, and as the walking wheels roll along the track 110, the input wheel 141 is driven to rotate forward. When the driving assembly 140 is located at the second position, the input wheel 141 meshes with the transmission gear at the second end of the sorting trolley 12, and as the walking wheels roll along the track 110, the input wheel 141 is driven to rotate reversely.

[0068] Wherein, the direction of passive rotation of the input wheel 141 when the driving assembly 140 is located at the first position is opposite to the direction of passive rotation of the input wheel 141 when the driving assembly 140 is located at the second position, the input wheel 141 with opposite rotation directions drives the articles conveyed by the conveyor belt 130 in opposite directions, so that the conveyor belt 130 selectively conveys the articles in the first conveying direction or the second conveying direction. Specifically, when the driving assembly 140 is located at the first position, the input wheel 141 is passively rotated forward, and drives the conveyor belt 130 to convey the articles in the first conveying direction; when the driving assembly 140 is located at the second position, the input wheel 141 is passively rotated reversely, and drives the conveyor belt 130 to convey the articles in the second conveying direction.

[0069] Further, the driving assembly 140 also has a standby position, when the driving assembly 140 is located at the standby position, the input wheel 141 does not rotate, that is, the conveying belt 130 is not moved, and only plays a role of supporting the articles, the conveying belt 130 supports the articles and moves along the track 110 with the sorting trolley 12. In the embodiment, when the driving assembly 140 is located at the standby position, the input wheel 141 is out of contact with the rack 11, that is, the input wheel 141 cannot rotate and drive the conveying belt 130 to convey the articles to the drop port even if the sorting trolley 12 moves along the track 110.

When the input wheel 141 drives the transmission wheel 149 to rotate, the transmission wheel 149 can drive the two rollers 148 located on both sides of the transmission wheel 149 to rotate at the same time through the driving shaft 144, so as to balance the friction between the two rollers 148 and the conveying belt 130, improve the reliability of the conveying belt 130 conveying the articles, and be beneficial to improving the compactness of the structure of the driving assembly 140.

[0071] Further, please refer to Figure 7 As shown in the figure, the sorting trolley 12 also includes two elastic assemblies, the two elastic assemblies are both arranged on the support 120, and in the conveying direction of the conveying belt 130, the two elastic assemblies are respectively arranged on both sides of the driving assembly 140.

In the embodiment, the first friction surface 111 and the second friction surface 113 are arranged oppositely, so that, when the first elastic component 159 abuts against the movable frame 142, the driving assembly 140 has a tendency to move away from the first position and close to the second position, so that the input wheel 141 presses the first friction surface 111; when the second elastic component 160 abuts against the movable frame 142, the driving assembly 140 has a tendency to move away from the second position and close to the first position, so that the input wheel 141 presses the second friction surface 113. In other embodiments, the first friction surface 111 and the second friction surface 113 are arranged oppositely, so that, when the first elastic component 159 abuts against the movable frame 142, the driving assembly 140 has a tendency to move away from the first position and away from the second position, so that the input wheel 141 presses the first friction surface 111; when the second elastic component 160 abuts against the movable frame 142, the driving assembly 140 has a tendency to move away from the second position and away from the first position, so that the input wheel 141 presses the second friction surface 113.

[0075] Optionally, the first elastic component 159 and the second elastic component 160 are symmetrically arranged.
