To the problem that exists in the above-mentioned prior art fireworks manufacturing, the utility model provides a make up formula fireworks with full cardboard that the cardboard stack formed with airflow channel's base and the bonding of paper launch canister form.

The technical scheme adopted for solving the technical problem is as follows: the utility model provides a full cardboard combination formula fireworks, it includes launching tube and base, the launching tube is built-in to be filled with the bullet and bind into launching tube wholly, the base is including all making from last to stromatolite adhesive upper substrate, intermediate lamella and infrabasal plate down with the cardboard, the interval is provided with the water conservancy diversion hole corresponding with launching tube quantity and distribution position on the upper substrate, the interval is provided with the air current passageway corresponding with water conservancy diversion hole quantity and distribution position on the intermediate lamella, air current passageway includes that at least two correspond communicating drainage mouth with the water conservancy diversion hole and be used for communicating with each other and connect the direct current way between the guide, air current passageway links to each other with the ignition head, be provided with the colloid ring layer between whole lateral surface lower extreme of launching tube and the upper substrate.

The upper substrate, the middle plate and the lower substrate are all made of paperboards with the thickness of 1-3 mm, the diversion holes are formed on the upper substrate in one step through punching dies, and the diversion ports and the direct current channels are formed on the middle plate through one step through machining through the punching dies.

The utility model discloses an innovation point lies in: the fireworks base that has airflow channel who makes with the injection molding combination now designs into the fireworks base that the whole part forms and has airflow channel with the cardboard combination, and its purpose is high in order to solve the injection mould that has airflow channel's fireworks base that makes with the injection molding combination and deposits, and manufacturing cost is relatively high, and mould material consumption is big, and the cycle length of manufacture is long, and a specification fireworks base will prepare one set of mould at least, and mould is in large quantities, its expense cost higher scheduling problem, the utility model discloses make fireworks manufacturing technique have new technological breakthrough, step forward a big step, brought unexpected technological effect for fireworks manufacturing.

Combined type fireworks base that full cardboard was made can satisfy fireworks and set off technical requirement, can simplify fireworks base structure again, make base processing convenient and fast more, shortened base manufacturing cycle, not only reduced base manufacturing cost, weight and plastics consumption, plastic mold quantity and manufacturing cost have been reduced, and eliminated fireworks and set off safety, especially can solve the fireworks and set off the series problem that takes place the mute and come, it has reduced fireworks manufacturing cost, fireworks manufacturing efficiency has been improved, the potential safety hazard in fireworks and set off has been eliminated, and be favorable to environmental protection and fireworks large-scale production.
