[0022] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0023] See Figure 1 This embodiment discloses a timed self-test voice prompt device for a cigarette packaging machine, including a power module, a peripheral signal conversion module, a button module, a microcontroller control module, a display module, a voice module, a power amplifier module, a volume adjustment potentiometer, a speaker, and a relay module.
