[0029] Further, the butt joint lower pipe 33 extends out of the upper and lower end surfaces of pipe support 32, so that the butt joint lower pipe 33 has space and is connected with butt joint upper pipe 34 and downwardly discharged, and the number of butt joint lower pipe 33, material pipe 12 and fireworks gunpowder cartridge corresponds.

[0030] Further, pipe head 13 is a separately lengthened part at the upper end of material pipe 12, so as to be communicated and conveyed with butt joint lower pipe 33.

[0031] The powder is stored in batches by the storage cylinder 2 entering the upper die 11, and during the moving of the pipe frame 32, the upper pipe 34 is inserted into the discharging port 21 to receive the powder, and the powder is stored in the lower pipe 33 and the upper pipe 34 in a quantitative manner, and during the moving of the pipe frame 32 downwards, the lower pipe 33 is inserted into the pipe head 13 to communicate, so that the powder is injected into the pipe 12 to realize the injection of the powder into the firework tube, and the powder in the multiple firework tubes can be injected at the same time, the amount of the powder is ensured, the normal production and processing of the firework is ensured, and the threaded upper pipe 34 is used to increase or decrease the distance between the upper pipe 34 and the lower pipe 33, so as to change the amount of the powder, control the amount of the powder during the injection, improve the injection efficiency, and increase the application range and capacity.

[0032] As a further provided embodiment of the utility model, the upper die 11 is fixedly provided with a hydraulic rod 3, the output end of the hydraulic rod 3 is fixedly provided with a support 31, and a plurality of pipe frames 32 are fixedly arranged on the support 31.

[0033] Specifically, the hydraulic rod 3 and the mounting mode thereof are prior art, and will not be repeated here, the support 31 has a plurality of branches for connecting the pipe frames 32, and the number of the branches corresponds to the number of the fireworks to be injected.

[0034] The pipe frame 32 is uniformly moved up and down by the hydraulic rod 3, so that the lower pipe 33 and the upper pipe 34 loaded with the quantitative powder are more stable during the moving, and the powder is not easy to be spilled, and meanwhile, the deviation during the connecting process is avoided.

[0035] As another further provided embodiment of the utility model, the lower end of the lower pipe 33 is slidably provided with a discharging element 4, and the discharging element 4 is circumferentially provided with an opening and closing piece 41 for opening and closing the pipe head 13.

[0036] Specifically, the opening and closing piece 41 closes the lower end of the lower pipe 33 in the default state, so that the powder in the lower pipe 33 is not easy to be leaked during the moving, and the opening and closing piece 41 is hinged to the inner ring of the annular discharging element 4, and a torsional spring is arranged at the hinged position, and the mounting mode of the torsional spring is prior art, which will not be repeated here.

[0037] Further, the inner ring diameter of the discharging element 4 is greater than the outer ring diameter of the pipe head 13, so as to be inserted and discharged.

[0038] The discharging element 4 at the lower end of the lower pipe 33 is sleeved on the pipe head 13, and during the moving of the lower pipe 33 downwards, the opening and closing piece 41 is pressed and inclined upwards, the lower end of the lower pipe 33 is opened, and the powder in the lower pipe 33 is discharged into the pipe head 13, so that the discharging process is more convenient and efficient.
