Description
Technical field
The present invention relates to old paper is made paper pulp the used paper mold ball skin for skyrocket of moulding dome-type.
Background technology
That that generally view and admire usefulness is called the structure of the lift-off fireworks of " chi jade " or " cutting thing ", by shell case be contained in its inner bursting charge and constitute for a lot of stars of performing firework effect and the four elements that is drawn out to the blasting fuse of shell case outside.
Shell case generally is to be made of the solid paper that the old paper applying multilayer with old newspaper etc. forms the endothelium of semi-spherical shape and sticks thick packing cardboard or brown paper etc. in the outside of endothelium, arrange a plurality of stars that various gunpowder classes made the dumpling shape respectively in the interior usefulness of a pair of endothelium, behind the bursting charge of side filling within it, sphere will be combined between the endothelium, then, make integrated and finish at fit the thickly crust that constitutes by brown paper etc. of periphery.
The lauching method of these fireworks can be by in the launching tube that firework bomb is packed into, lights the priming in the tube and finishes.
At firework bomb in launching tube emission, light the outer end of blasting fuse by the fiery inflammation of its priming, keep suitable time delay up to reaching the desirable height of lift-off, then light inner bursting charge, when shell case is broken, scatter and burn into the chrysanthemum shape by star, form the pattern of its spark aloft in the short time.
As the function of the shell case of above structure, requirement can be given full play to the effect that scatters of the blast of bursting charge, and self becomes comminution ground and disperse, promptly, shell case do solid more firmly, the effect that scatters of the blasting energy by bursting charge is high more, can become the very big shape of scope.
, it is traditional industry substantially that above lift-off fireworks are made, and makes the requirement condition height by hand., owing to the lift-off fireworks unexpected prosperity already of various places, the fireworks requirement increases day by day recently.
Corresponding therewith, the fireworks practitioner is also adjusting the volume increase system, but in each production process, owing to being makes shell case by hand with method in the past to be unable to catch up with producing needs, it is special because endothelium is that multilayer laminated applying newspaper makes hemispheric operation, production efficiency is poor, and also needing in appearance skillfully becomes the weak link of volume increase.
For head it off, recently, replace hemispherical by former hard letterweight being made type as endothelium.
Because this cardboard compression moulding endothelium is a machinery production, so shape is even and output is high.In addition, owing to be that solid firm paper is made, so can make the effect that bursting charge scatters by endothelium.
, in fact, need big pressure during this cardboard compression moulding endothelium moulding, and must downcut periphery with cutting knife after the compacting and be processed into hemispherically, it is good to be called processing and forming thus, its cost height, and intensity is excessive, therefore, the bursting charge explosion time can not be crushed into Powdered and become a plurality of separations of fragments, if the explosion dose is few, break from commissure often and fly out, not only dangerous when falling, and hinder scattering of star, then can not get the layout effect of being imagined.
Therefore, the applicant is for solving the result that above-mentioned problem is in the past studied repeatedly with keen determination, developed old paper paper pulpization with old newspaper etc., molded copy paper become hemispherical after, carry out hot pressing, inner and outer circumferential surfaces is made the lift-off fireworks shell case of level and smooth regeneration ground paper formed body structure endothelium, and at first proposed application.Promptly, these lift-off fireworks are inexpensive and can produce in a large number with shell case, also can overcome because hardness and the too high problem that causes of intensity, and can form inner and outer circumferential surfaces smoothly after the hot pressing, peel off so can prevent the gunpowder of star outer peripheral face, and also good to the stickiness of outer peripheral face applying brown paper.
, in further afterwards the research and development.For this lift-off fireworks shell case of at first applying for, room for improvement is arranged at following point.
Promptly, owing to be with old paper paper pulpization, the molded paper of copying becomes hemispheric shell case, the reverse side that scatters is pulverized in blast by bursting charge easily, if when the inner peripheral surface of its fragment that scatters adheres to bursting charge securely, particularly during the big bullet more than making about No. 10 bullets, the residual fire of bursting charge is from being moved and may continue flameless combustion after falling earthward by chippy cataclasm.
The present invention is in order to solve above-mentioned problem, its purpose is to provide inexpensive and when producing in batches, not only can prevent because the peeling off of the outer coplanar bursting charge of problem that hardness and intensity cause or star, and the residual fire of bursting charge is moved and continue aphlogistic used paper mold ball skin for skyrocket and manufacture method thereof.

(5) hot pressing operation
Since use 14 pairs of dryings of net molding jig regeneration ground paper formed body 16 copy paper, have fine concavo-convex asperities and can not become level and smooth sphere so its inner and outer circumferential surfaces forms.Therefore, after dry the end of a period, when the inner and outer circumferential surfaces of its formed body 16 carried out hot pressing processing in the hot pressing cutting machine 22 of interior outer mold 22a, 22b with semi-spherical shape, punching press severing semi-spherical shape part forms the endothelium 1 that the regeneration ground paper formed body of uniform 6 semi-spherical shape of thickness with level and smooth inner and outer circumferential surfaces constitutes.
At this, hot pressing type temperature is controlled at 140～150 ℃, pressing pressure is controlled at 200kg/cm
2About, carrying out twice exhaust compacting, the wall thickness after the compacting preferably makes about 6.5mm.
In addition, when old paper is carried out paper pulp, do not need bleaching, therefore, its color is a grey, behind the bonding old newspaper of lamination, with the hemispheric hemisphere that is identically formed the band flexibility of moulding.In addition,, for example when No. 5 play, copy paper and form about 3～5mm thickness by 6 hemispherical regeneration ground paper formed bodys 16 that constitute, be compressed into about 2～3mm thickness by hot pressing after, become each endothelium 1 of semi-spherical shape with these hot pressing cutting machine 22 severings.In addition, when playing, copy paper and form about 5～10mm thickness for No. 7.After being compressed into about 3～7mm thickness by hot pressing, severing becomes each endothelium 1 of semi-spherical shape.
The diameter of this endothelium 1 and wall thickness can determine various types of according to the specification of inserting its inner star and explosion dose.
That is, carry out fire-retardant processing and handle and the endothelium 1 of manufacturing, the compression of outer surface infiltration at least within it fire retardant tries hard to improve fire line.And then carry out waterproof processing to handle and the endothelium 1 of manufacturing, except fire line, also improved moisture-proof as much as possible.
In addition, by formation sphere that above-mentioned endothelium 1 is just being united two into one, but side's inner bottom part center has the hole 1a that blasting fuse is used therein.At this moment, for cardboard compression moulding endothelium in the past, because moulding poling hard, so when compression moulding, must use the hole by punching press formation blasting fuse, but, also can carry out punching processing when beginning to copy paper because its flexibility also forms the hole easily by spindle processing from behind.
In addition, also the edge portion of the mating surface of two endotheliums 1 can be formed concavo-convexly, at this moment, decide two positions when cooperating reliably.
Below, describe according to the installation steps of the lift-off fireworks that use above-mentioned endothelium 1.At first, owing to this endothelium 1 is to form with soft material, warp so might when filling gunpowder, be out of shape.Therefore, shown in Fig. 4 (a), in advance this endothelium 1 is entrenched in the assembling fixture 2 of the semi-spherical shape that constitutes by the cardboard compression moulding body that has with endothelium external diameter same inner diameter, then shown in Fig. 4 (b), all proper alignment within it is a granulated into a plurality of stars 3 of dumpling shape.At this, above-mentioned assembling fixture 2 is not limited to cardboard compression moulding body, also can be wooden, resin system etc.But,,, wish to use dielectric material, preferably without metal for this assembling fixture 2 from preventing the viewpoint of gunpowder firing accident.
Then, shown in Fig. 4 (c), will separate the interior week that paper 4 is configured in star 3 by what newspaper etc. constituted, side is filled bursting charge 5 within it.
That is, in endothelium 1, during the assembling of filling star 3 or bursting charge 5, endothelium 1 is entrenched in the assembling fixture of being made up of the non-conductive material of the inner face with the semi-spherical shape that equates with its outer radius surface 2, strengthens from outer circumferential side assembling under the state of its endothelium 1.
If finish above two operations, shown in Fig. 4 (d),, finish padding if merge two endotheliums by operating fast with anchor clamps 2, form the proper sphere shape.
In addition, on a side endothelium 1, will be incorporated into the position of bursting charge 5 by the blasting fuse 6 of its blasting fuse hole 1a in advance certainly.
Then, after adhesive tape on the mating surface periphery of endothelium 1 volume is fixing, unload lower clamp 2,, as shown in Figure 5, make the incorporate lift-off fireworks of periphery of thick crust 7 with endothelium according to the solid paper of established methodology at its periphery multilayer ground lamination applying brown paper etc.In addition, symbol 8 is the tip positions that are fixed on crust 7 among the figure, the suspension ring of available rope hanging fireworks.
The lift-off fireworks of above structure, explosion time aloft, because endothelium 1 becomes comminution ground and disperses to the four directions, so be safe from danger or for the obstruction of layout shape, in addition, owing to use old paper recycled writing paper basically, so with cardboard compression moulding endothelium ratio in the past, raw material cost reduces, and turns back to easily on the ground, also suits on ecology.
In addition, because endothelium 1 is to impose hot pressing processing compression forming, so when inserting gunpowder, inner peripheral surface can recessedly not be out of shape, in addition, owing to form inner peripheral surface glossily, so even the inner peripheral surface of the peripheral part of star 3 and endothelium 1 rubs and also prevents peeling off of gunpowder as much as possible when inserting gunpowder.And then, because also formation glossily of outer peripheral face, so the adhibit quality of brown paper etc. is also good.
And then, because the infiltration of inner and outer circumferential surfaces at least compression fire retardant and waterproofing agent at endothelium 1, so not only can prevent to move and flameless combustion, have good fire line thus, and have good moisture-proof when preserving attached to the residual fire of the bursting charge of the inner surface of chippy fragment.
In addition, for above embodiment, the lift-off fireworks of so-called bursting charge only are described, but the lift-off fireworks that are called the non-unity structure that hangs thing (ball pokes fire) also are applicable to the present invention, this need not wait to say.
The utilizability of industry
