[0002] During the production process of combined fireworks, it is necessary to complete the work of filling the inner tube (also called effect tube, effect piece, etc.) into each firing hole of the outer tube of the combined fireworks; the inner tube of the traditional combined fireworks is filled manually, which requires a large number of workers to install at the same time and is inefficient, but since there is a risk of explosion when installing the inner tube, the existing general inner tube mechanical equipment is used for filling; when mechanical equipment is used for filling, due to safety production requirements, the inner tube is first filled into the mold at a first station, and then the mold is transferred to a second station to install the inner tube in the mold into the combined fireworks group basin, wherein a partition wall is provided between the first station and the second station.

[0003] The Chinese patent document with publication number CN210321440U discloses an effect inner cylinder filling device, which uses an inner cylinder positioning and flipping assembly to horizontally fill the effect inner cylinder and then flip it vertically to fill it into the cylinder of the combined firework body, and moves through a moving seat so that it can fill the effect inner cylinders of different rows of cylinders of the combined firework body. Multiple inner cylinder filling devices can fill effect inner cylinders with different effects according to product needs, thereby forming the required firing effect of the combined firework body. The effect inner cylinder filling speed is fast and the effect inner cylinder is accurately filled in place. However, when the device is filling the inner cylinder, the structure of the inner cylinder positioning and flipping assembly is complicated, and if the firework inner cylinder is not in place during operation, it will get stuck.
