[0002] In prior art, the powder pressing machine for building and pressing fireworks powder is used for the powder pressing procedure of fireworks effect component (such as: powder column, handle, rotating flower and flute sound powder bare powder effect component or with barrel effect component). Generally, it is four-column structure. For example, the "mould pressing device of fireworks powder column" disclosed in the Chinese patent document with announcement number CN221037116U is supported by four support rods 103 for building and pressing. Its defect is that it cannot continuously build and press, and only one barrel cake (generally, multiple firework barrels are arranged in parallel and bunched into hexagonal structure) can be built and pressed each time, and the oil press needs to manually replace barrel cake after each time of pressing, so the efficiency is low. Therefore, we have also developed equipment capable of continuously pressing powder, such as the "fireworks inner barrel powder building and pressing equipment" disclosed in the Chinese patent document with announcement number CN221173155U. However, this continuously working device uses conveying belt 20, and fireworks powder building and pressing belongs to high-risk procedure, which needs to strictly prevent friction or electrical spark that may ignite dust, and has strict powder amount limit, so its application is limited.

[0024] The limiting screw 601 is arranged at the four corners of the pressing rod positioning template 6, and the limiting screw 601 is threadedly connected with the pressing rod positioning template 6, and the bottom end of the limiting screw 601 abuts against the lower surface of the pressing plate 5.

[0025] The T-shaped groove 602 is arranged at the middle part of the three outer sides of the pressing plate 5, the T-shaped bolt 603 is assembled in the T-shaped groove 602, the supporting block 604 is installed on the T-shaped bolt 603, the supporting block 604 is inserted into the lower surface of the pressing rod positioning template 6 to support the pressing rod positioning template 6, and the supporting block 604 is also threadedly connected with the adjusting screw 605, and the upper end of the adjusting screw 605 abuts against the lower surface of the pressing plate 5. The adjusting screw 605 is convenient for adjusting the stress in each direction of the pressing rod positioning template 6, adjusting the gap and level between the pressing plate 5 and the pressing rod positioning template 6, adapting to the possible differences between different barrel cakes, and ensuring the balance of pressing.

[0026] The pressing rod positioning template 6 is provided with a plurality of upper positioning holes 606, the top parts of a plurality of pressing rods 8 are respectively hoisted in the upper positioning holes 606, and the pressing plate 5 abuts against the top end of each pressing rod 8 when being pressed, and the pressing rod 8 can be sleeved with a buffer spring (not shown in the figure).

[0027] A rotating disc 10 is installed on the base 2 below the stripper plate 9, and three cylinder positioning mechanisms 11 are distributed around the rotating disc 10.

[0028] The stripper plate 9 is provided above each cylinder positioning mechanism 11, and the four corners of the stripper plate 9 are fixed to the rotating disc 10 by four supporting rods 901. The stripper plate 9 is provided with a plurality of lower positioning holes 902, and the number and position of the lower positioning holes 902 correspond to those of the upper positioning holes 606.

[0029] The utility model breaks through the limitation of four-column positioning, provides the basis for continuous work of the rotating disc through the supporting arm lifting mode, and the device can stably bear the working pressure required for pressing the explosive (generally 30-50 tons of oil press); the rotating disc 10 can be driven by a hydraulic pressure (such as a hydraulic indexing disc), realizing the electrification-free of the work site; the rotating disc structure is easy to clean, and there is basically no dead angle for hiding dust; therefore, the safety hazard is greatly reduced.
