So far, the staff usually use a device to compact the pyrotechnic powder in the fireworks tube after filling it into the fireworks tube, so as to improve the quality of the pyrotechnic powder. Since the pyrotechnic powder is prone to uneven distribution and bubble gaps during the filling process, the current pyrotechnic powder filling device is not convenient for stirring the pyrotechnic powder inside the fireworks tube when filling the pyrotechnic powder, which leads to uneven filling of the pyrotechnic powder, and the existing pyrotechnic powder filling device is not convenient for vibrating the pyrotechnic powder inside the fireworks tube, which leads to the ineffective removal of the bubble gap inside the pyrotechnic powder, which leads to insufficient filling of the pyrotechnic powder, resulting in poor filling quality of the pyrotechnic powder.
