Problems solved by technology
The current production process of combined small fireworks shells needs to connect the ignition leads of small fireworks shells one by one in series, and repeatedly bind them with adhesive tape to shape them, which consumes a lot of labor.
There are technical defects such as low labor production efficiency and unsatisfactory dispersion effect after launch

Embodiment Construction
[0012] refer to figure 1 and figure 2 , the manufacturing process of combining small display shell fireworks, including the following process steps:
[0013] 1) Making the inner cylinder: use a reel machine to process the special paper into a cylinder body 1 according to the design specifications, open several holes 2 in the cylinder wall, and seal the bottom of the cylinder with cardboard and tape;
[0014] 2) Propellant loading: put the propellant package 4 provided with the main ignition lead 3 into the bottom of the inner cylinder, one end of the main ignition lead 3 is connected to the propellant, and the other end extends out of the cylinder body 1. The length of the main ignition lead 3 is according to Need to set;
[0015] 3) Installing small fireworks shells: placing a number of small fireworks shells 5 with timing leads 6 in the barrel;
[0016] 4) Sealing: Use cardboard and adhesive tape to seal the inner cylinder mouth.
[0017] Explosion instructions: place t...

The invention provides a process for manufacturing combined small display-shell fireworks. The process comprises the following steps: using a reeling machine to pull a cylinder, providing the wall ofthe cylinder with a plurality of holes, sealing the bottom of the cylinder with a paper board and tape and putting a propellant bag provided with a main ignition lead into the bottom of an inner cylinder; allowing one end of the main ignition lead to be connected with propellant and allowing the other end of the main ignition lead to protrude out from the cylinder; placing a plurality of small display shells having timing leads in the cylinder; and using the paper board and the tape to seal the mouth of the inner cylinder. The process solves the technical problems of reasonably connecting andstably emitting a plurality of small display-shell fireworks. The process is simple. In the setting-off process, the small display shells go out of the cylinder and then rise to a plurality of positions with more stable emitting effect and better setting-off effect.
Description
technical field [0001] The invention relates to a production process of fireworks, in particular to a production process of combined small fireworks shells fired with multiple bombs simultaneously. Background technique [0002] Small fireworks shells are also called small artillery shells. The combination of small fireworks shells fired with multiple shells is to connect small shells one by one through the lead wires, and use tape to repeatedly trap them to form a whole. When setting off, put the combined small fireworks bombs fixed into an integral structure into the launch tube, ignite and launch, and multiple small fireworks bombs are lifted into the air and explode at the same time, producing various sound and light effects. The current production process of combined small display shell fireworks needs to connect the ignition leads of the small display shell fireworks one by one in series, and repeatedly bind them with adhesive tape to shape them, which consumes a lot of...
