[0038] To avoid poor flowability of the falling powder, affecting the efficiency of the powder filling, and prone to inaccurate metering, resulting in too much powder that can easily cause the blast, and too little powder that can not guarantee the quality of the firecracker, therefore, when filling the firecracker barrel 101 with powder, the powder needs to be quantified, first align the firecracker barrel 101 with the discharge hole of the support plate 201, then the staff pours the powder into the discharge frame 2, the powder flows into the storage hole of the distribution plate 4 through the discharge hole of the discharge frame 2, under the action of the distribution plate 4, the powder can be quantified to avoid too much or too little powder. When the powder in the discharge frame 2 stops flowing, the staff starts the air cylinder 3, the extension of the extension rod of the air cylinder 3 drives the distribution plate 4 to move to the right, the extension rod of the air cylinder 3 pulls the push frame 8 up through the pull rope 7, the first pressure spring 9 is compressed, so that the push frame 8 dredges the powder, increases the flowability of the powder, and then the powder continues to enter the storage hole of the distribution plate 4, so that the storage hole of the distribution plate 4 is filled with powder, thus avoiding poor flowability of the powder due to blockage, which can not fill the storage cylinder of the distribution plate 4 with powder, affecting the quantification of the powder by the distribution plate 4, thereby affecting the quality of the firecracker.

[0044] In order to ensure that the gunpowder powder can smoothly enter the firecracker barrel 101, and avoid that the gunpowder powder will be pushed out of the discharge hole of the support plate 201 due to excessive pressure, when the distribution plate 4 moves to contact the inclined surface of the pressing frame 19, the distribution plate 4 presses the pressing frame 19 to move downward, the third pressure spring 21 is compressed, the pressing frame 19 presses the cross-shaped silica gel valve 16 to open, thereby reducing the air pressure in the discharge hole of the support plate 201, avoiding that the gunpowder powder entering the discharge hole of the support plate 201 will be pushed out by the airflow generated by the excessive air pressure, and affecting the accuracy of the filling amount of the gunpowder powder into the firecracker barrel 101, when the distribution plate 4 moves to the left to reset, the third pressure spring 21 resets to drive the pressing frame 19 to move upward to reset, the cross-shaped silica gel valve 16 automatically closes to block the gunpowder powder, preventing the gunpowder powder from flowing back.
