[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The automatic quantitative loading mechanism for raw materials used in fireworks production supports the fireworks barrel through a bearing block, and utilizes the rebound force of the spring to prompt the rebound plate to push the push plate to move. At this time, the push plate will push the clamping plate to press the fireworks barrel to achieve its fixation. The controller controls the motor to start and drive the rotating disk to rotate. The rotating disk drives the assembled fireworks barrel to the bottom of the discharge tube.
