Code spraying conveyer of electronic tag picking system

The utility model relates to a code spraying conveyer of an electronic tag picking system, which comprises a frame and a code spraying machine, a conveyer belt around the frame, a motor fixed in the frame, a motor transmission conveyer belt, a sensitimeter fixed on the frame, and a code spraying head in the code spraying machine, and is characterized in that the a section of an auxiliary frame consisting of the motor transmission conveyer belt with different speeds is arranged on the fixed sensitimeter and the frame end of the code spraying head in the code spraying machine at intervals. The transmission speed of the previous section of the conveyer belt of the code spraying machine is slightly lower than that of the conveyer belt on which the code spraying machine is on, so that speed difference is formed, the distance of the bar codes can be increased without affecting the original operation efficiency, so as to meet the necessary conditions of the code spraying of the code spraying head, and avoid code omi
