[0027] Specifically, the first sliding rod 34 is limited by providing a vertical sliding groove 33 .

[0028] like Figure 3 As shown, the motor 35 is fixedly connected to the back outer wall of the box body 31, the front output end of the motor 35 passes through the front and rear ends of the back inner wall of the box body 31, the rear end of the transmission shaft 36 is fixedly connected to the front output end of the motor 35, the eccentric turntable 37 is fixedly connected to the middle part of the transmission shaft 36, the number of rollers 310 is five, and the five rollers 310 are rotatably connected to the inside of the box body 31, and the five rollers 310 are arranged with the transmission shaft 36 as the center of the circle.

[0029] Specifically, the roller 310 is provided to limit the position of the eccentric rotating disk 37 when it rotates.

[0030] like Figure 3 As shown, the circular slide groove 38 is opened on the circumferential outer wall of the eccentric rotating disk 37 , the ball 39 is slidably connected inside the circular slide groove 38 , and the ball 39 is fixedly connected to the top of the first slide rod 34 .

[0031] Specifically, the inner diameter of the firework shell 5 is consistent with the outer diameter of the dredging tube 4. The eccentric turntable 37 rotates to drive the ball 39 and the first slide bar 34 to move up and down. The first slide bar 34 moves up and down to drive the dredging tube 4 to be inserted into the firework shell 5, flattening the burrs and protrusions on the inner wall of the firework shell 5.

[0032] Embodiment 2

[0033] like Figure 1-4 As shown, a filling mechanism 6 is provided inside the dredging pipe 4 , and the filling mechanism 6 includes a spherical bin 61 . The spherical bin 61 is opened inside the dredging pipe 4 , and gunpowder is provided inside the spherical bin 61 . A horizontal plate 62 is fixedly connected to the top of the spherical bin 61 .

[0034] Specifically, the gunpowder is stored by providing a spherical warehouse 61 .

[0035] like Figure 4 The top of the spherical bin 61 is fixedly connected with a horizontal plate 62, the top of the horizontal plate 62 is slidably penetrated by a second slide rod 63, the bottom end of the second slide rod 63 is fixedly connected with a ball valve 64, the ball valve 64 is arranged inside the spherical bin 61, the outside of the second slide rod 63 is sleeved with a spring 65, the bottom end of the spring 65 is fixedly connected to the top end of the ball valve 64, and the top end of the spring 65 is fixedly connected to the horizontal plate 62.

The dredging tube 4 moves downward to drive the top block 66 to move downward. The top block 66 moves downward and contacts with the top rod 67 and is lifted. After being lifted, the top block 66 drives the ball valve 64 to move upward. When the ball valve 64 moves upward, it compresses the spring 65. At this time, the gunpowder in the ball-type bin 61 loses the obstruction of the ball valve 64 and flows into the interior of the firecracker shell 5 through the dredging tube 4 to achieve filling. Subsequently, when the dredging tube 4 returns upward, the spring 65 rebounds and drives the ball valve 64 to return downward. At this time, the ball valve 64 blocks the ball-type bin 61 again.
