Description

Rubbing firecracker

What the utility model provided a kind industrial art field is the red celebrating and major holiday in vain to increase lively firework atmosphere, that be provided with lead-in wire, particularly wipes big gun.

No matter existing firework is firecrackers or single firework, and the lead-in wire that all has one section interior thorax of insertion firework and bursting charge to link is for the usefulness of lighting when setting off.Be exactly the lead-in wire that this section exposes firework, because most of manufacturers all are manual operations, unavoidable length unanimity.If the lead-in wire that exposes has been grown, in case promptly dish out after lighting, then may working as will soon go between to touch when firework lands goes out, and does not reach quick-fried loud purpose; If the lead-in wire that exposes has been lacked, not having enough time to dish out after then lighting probably is quick-fried sound, causes blast accident.

Based on existing firework above shortcomings, the purpose of the utility model is to design and a kind ofly need not to go between, need not naked light and directly light and can realize the safe and reliable wiping big gun that fires effect.

The primary structure feature of this wiping big gun is, medicine when one section control is equipped with near the bursting charge place in thorax top is within it seted off 3～6 seconds time in order to control, and medicine place point has the wiping duration and degree of heating when being right after control on its top, and rubbing with matchbox phosphorus sheet with this when setting off fires.

Because the design's wiping big gun has the said structure feature, therefore brought following advantage:

The one, set off conveniently, without the naked light burning-point, have only and it is wiped duration and degree of heating can reach and fire effect wiping combustion on the matchbox phosphorus sheet or on other phosphorus sheet;

The 2nd, the dephosphorization sheet can be wiped outside the combustion, other anything all can't wipe combustion, carrying is perfectly safe;

The 3rd, the effect of medicine so stopped fast quick-fried accident, is seted off safe and reliable when controlling because of having;

The 4th, wipe combustion after, can be in water quick-fried sound, can not extinguish because of circuitous water;

The 5th, reduce peace and drawn, adorned closure agent and spray alcohol operation, can reduce product cost, enhance productivity.

Its technological process is: cut a sheet of paper-→ reel-→ when control dress medicine-→ the dress bursting charge-→ the dress sealing compound-→ wipe duration and degree of heating-→ back of the body ticker tape dress box-→ become case.

The prescription of medicine is (by weight percentage) when wherein controlling:

Barium nitrate 20～30 potassium nitrate 10～20

Strontium carbonate 10～20 charcoals 5～15

Sulphur 5～15 resins 5～10

The prescription of wiping duration and degree of heating is (by weight percentage):

Potassium chlorate 40～50 silica flours 30～40

Resin 5～10 antimony trisulfides 2～10

As for the prescription of bursting charge, basic identical with existing firework.

Below in conjunction with accompanying drawing production process of the present utility model is done to describe in detail.

Accompanying drawing 1 is a structural representation of the present utility model, and numbering is respectively among the figure:

1-sealing compound 2-bursting charge 3-paper web

Medicine 5-wipes duration and degree of heating during the 4-control

The description requirement different according to firework, the operation of at first cutting a sheet of paper (teams and groups or workshop section or workshop) is cut paper and is cut down material; Transporting rolls operation or be distributed to the individual, it is good to cut out several good quires before the reel so that be rolled into satisfy in the paper web 3 of garden and wall thickness dimension requirement; Then forward the powder charge operation to, in paper web earlier dress prepare by prescription control the time medicine 4 and compressing in right amount, refill the bursting charge 2 that has prepared, also compress in right amount, the 3rd step sealed with sealing compound 1; After treating that sealing compound is done, shift next procedure, and with paper web 3 tunes, medicine 4 places on the paper web top and when being close to control, the wiping duration and degree of heating 5 for preparing by prescription on the point; After waiting to wipe duration and degree of heating and doing, go to assembly process (teams and groups or workshop section or workshop), wrapped a chromatics paper seal dress box, last total inspection vanning in paper web 3 peripheries before this.

Claims (2)

1, a kind industrial art for red white celebrating and major holiday increase lively atmosphere need not go between and wiping big gun that naked light is directly lighted is made up of paper web 3, bursting charge 2, sealing compound 1 etc., it is characterized in that one section medicine 4 can control the control of setting off time 3-6 second the time is equipped with near bursting charge 2 places in paper web 3 in thorax top and be close on paper web 3 tops that medicine 4 places point has wiping duration and degree of heating 5 when controlling.
