Abstract: Provided is a container autorotation device and method. The container autorotation device comprises a conveying rack used for conveying a plurality of containers, at least one container base connected therewith and comprising a container clamping end and a driving end, and a driving component used for driving the container base to autorotate and comprising a motor and a clamping part driven by the motor. A slot matched with the driving end is formed in the clamping part such that when the driving end moves into the slot and stay, the driving end is driven by the clamping part to rotate. The slot in the clamping part is designed so that the driving end is pushed against the slot when entering the slot and rotating in the slot. Autorotation is achieved with mutual cooperation between the clamping part and the driving end.
