Background

The existing driving device for the sorting machine mostly comprises an annular track and a plurality of trolleys, wherein the trolleys are connected through chains and driven to walk along the annular track through a driver. Because the dollies pass through the chain connection, when the dolly turned through the arc section, the interval between the dolly was the length of the chord line of the arc section between two dollies, and the interval between the dolly can reduce promptly to make the workshop can the workspace reduce, the mail on the dolly of below interferes with the friction drive mechanism of top dolly easily mutually, has the risk that the mail of below dolly dropped. In addition, chain connections have the following drawbacks: 1) the chain transmission can only transmit tensile force but not pressure, so that the chain transmission does not have the force transmission characteristic of a closed loop, and the trolley can be driven to travel along the annular track by a large driving force; 2) the chain structure needs to be guided when the arc section turns, the noise is high when the trolley runs at high speed, and the vibration is easy to generate due to the defects of the chain transmission when the trolley runs at high speed, so that mails on the trolley fall off; 3) the chain structure needs regular tensioning after long-time operation, and later maintenance cost is high.
