The existing circular sorting machine can generate the following problems in the operation process:
(1) the driving device and the sorting platform only have one contact surface, so that gaps are easily generated, and the driving force is unstable;
(2) the driving device and the bearing device are integrated, so that the driving device and the bearing device are easy to shake and slide relatively in the running process, the levelness of the bearing device cannot be guaranteed, and the service life of the bearing device is shortened due to long-time running;
(3) the fixed supporting force of the sorting platform is provided by a universal joint positioned in the center, and the relative position can be changed in the operation process without a limiting device.
The existence of above problem is restricting the letter sorting efficiency of circular sorting machine, can not satisfy the requirement of enterprise to commodity circulation letter sorting.
