It should be noted that in the embodiments of the present invention, all directional indications (such as horizontal direction, vertical direction, parallel setting, perpendicular setting, up, down, left, right, front, back...) are only used to explain the relative position relationship and movement conditions between each component in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indication also changes accordingly.

[0022] Reference Figure 2 , the primer detection device 40 is used to detect whether the primer is filled correctly. It is arranged between the primer filling device 10 and the fireworks paper filling device 20, conveys the qualified fireworks body 1 along the second conveyor line 200 to the fireworks paper filling device 20, and pushes the unqualified fireworks body 1 out in the vertical reverse direction by the first driving part cylinder 401.

[0023] The paper detection device 50 is used to detect whether the paper is filled correctly. It is arranged between the fireworks paper filling device 20 and the inner cylinder filling device 30, conveys the fireworks body 1 with qualified paper filling along the third conveyor line 300 to the inner cylinder filling device 30, and pushes the unqualified fireworks body 1 out in the vertical reverse direction by the second driving part cylinder 501.

[0024] Reference Figures 1 - 3 On one side of the firework paper filling device 20 for receiving the firework body 1, a firework body pushing device 60 is provided. The firework body pushing device 60 includes a third pushing cylinder 61, a first limiting cylinder 62, a second limiting cylinder 63, and a reversing motor 64 for the transposition member.

[0025] In the combined firework manufacturing process, the firework body 1 is composed of a plurality of firework outer cylinders arranged in rows and columns. First, the bottom gunpowder is filled at the bottom of the outer cylinder of the firework body 1, then the first layer of paper pieces (commonly known as paper cakes) is filled on the bottom gunpowder, then the effect inner cylinder is filled on the paper pieces, and then the second layer of paper pieces is filled on the effect inner cylinder. The firework body pushing device 60 of the present invention needs to complete the conveying task of filling paper pieces twice at one station. The second conveyor line 200 conveys the firework body 1 filled with bottom gunpowder from the right side of the firework body pushing device 60 into it, and the fourth conveyor line 400 conveys the firework body 1 filled with the inner cylinder from the left side of the firework body pushing device 60 into it. When the firework body 1 is conveyed to the station of the firework body pushing device 60, the third pushing cylinder 61 pushes the firework body 1 to the firework paper filling device 20 to complete the filling of paper pieces.
