[0002] At present, in the production process of fireworks, in order to facilitate the filling of gunpowder into the firecracker body, multiple fireworks bodies need to be clamped by a tight film. The specific method is to arrange multiple fireworks bodies and pre-fix them with paper strips. , and then put the tight hoop film outside the arranged fireworks body, but at present, the process of putting the tight hoop film outside the arranged fireworks body is done manually, because the tight hoop film is through the elastic hoop For those outside the arranged firecracker body, when the tight film is not fastened to the outside of the arranged firecracker body, the inner diameter of the tight film is smaller than the outer diameter of the arranged firecracker body. In this way, it is difficult to The clamping film is clamped to the outside of the arranged firecracker body

The invention discloses a firework fastening membrane assembling device. The firework fastening membrane assembling device comprises a bottom plate, the middles of the four side edges of the bottom plate are respectively welded with a support rod horizontally extending outwards, the outer end of every support rod is in hinged connection with a rotating rod for expanding a fastening membrane, and the lower end of every rotating rod is hinged to the outer end of the corresponding support rod; a push plate is arranged right above the bottom plate, the middles of the four side edges of the push plate are respectively welded with a pushrod horizontally extending outwards, the outer end of every pushrod is rotatingly connected with the corresponding rotating rod through a rotating shaft, and theinside of every rotating rod is provided with a long hole for the corresponding rotating shaft to slide in the length direction of the rotating rod; a driving mechanism for driving the push plate tomove up and down is arranged between the push plate and the bottom plate. The firework fastening membrane assembling device can conveniently expand the fastening membrane, therefore, the fastening membrane can be conveniently assembled outside a well-arranged firework body, and further firework production can be facilitated.
