Description

A kind of fireworks safety firing cable

Technical field

The utility model relates to the fireworks and firecrackers firing line, especially a kind of fireworks safety firing cable.

Background technology

The fireworks firing line is the pyrotechnic composition goods that are used for lighting a fire, passing fire, period, can be divided into the quick firing line of tissue paper firing line, safety firing cable and kraft paper according to the material of external parcel layer.The making method of various firing line has bigger difference.During fireworks were produced now, the use of safety firing cable was more and more, and safety firing cable is to be the medicine core with the pyrotechnic composition, makes the looping thing with cotton thread, knitted layer outside being made into, and was coated with the firing line with damp proof material outward.Be characterized in that the moistureproof and mildewproof performance is good, tensile strength is big, and is strong and tough and tensile, can be difficult to light from the firing line side direction at submerged combustion.

The making method of safety firing cable comprises following technical process in regular turn now:

One, firing line medication preparation:

1, selects the medicine proportioning: get rid of the impurity in the medicine and take by weighing medicine in proportion;

2, mixing screen medicine: powdered drug is mixed;

3, slurry medicine: add paste in the powder powder charge thing, compress with thorough mixing;

4, granulating and drying: rub the medicine granulation with the hands by screen tray and be 50-60 purpose fine particle and dry or dry;

5, sieve medicine: keep firing line size of pharmaceutical particles unanimity;

6, medicine of a cold nature warehouse-in: warehouse-in is standby after the firing line medicine that processes dispels the heat cooling fully.

Two, will go up the firing line medicine that processes in the step wiring machine drug bucket of packing into, on wiring machine with yarn braiding parcel firing line medicine:

As a kind of known technology, the braiding parcel of safety firing cable medicine adopts machinery---and common name " wiring machine " is finished, comprise braiding mechanism and winding mechanism, with the drug-leaking hole of a guiding cotton yarn by the wiring machine drug bucket, the firing line drug particles that drives in the drug bucket leaks down from drug-leaking hole, be in the process of leaking under the wire at the firing line drug particles, braiding mechanism is constantly with many cotton braid packaged tubes, guiding cotton yarn and firing line drug particles are wrapped up densely, this process is continuously carried out, and the safety firing cable work in-process of formation are through the winding mechanism coiled coil of wire of igniting.

Described safety firing cable work in-process structure is referring to Fig. 1, and the sleeve pipe that cotton braid 20 forms is wrapped in the medicine core 22 of the firing line drug particles formation of guiding cotton yarn 21 and wire arrangement.Described guiding cotton yarn 21 and medicine core 22 do not combine, and can be separated from each other after taking described cotton braid 20 apart.

Three, the safety firing cable work in-process of making in the above-mentioned steps are formed waterproof layer through japanning, and the air-dry finished product that makes.

Existing technique process is longer, complicated operation, and link hand-manipulated is many, and potential safety hazard point is many, and security incident happens occasionally; Simultaneously, also more by the safety firing cable quality problems of existing explained hereafter, occur disconnected medicine (interruption of firing line medicine core), few medicine (firing line medicine core diameter is less than normal value) easily, leak medicine phenomenons such as (the medicine core spill from surrounding layer); Moreover, the production of existing technology and use the Chinese traditional medicine dust too many, environmental pollution is big, not only forms serious potential safety hazard, even also easily workman's health is caused occupational illness injury such as silicosis in ordinary production.

The utility model content

In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of fireworks safety firing cable is provided, and its reliable product quality is stopped the generation of resolving medicine, few medicine, leaking the medicine phenomenon; Its manufacture craft flow process is comparatively simple simultaneously, and the Safety and Environmental Protection of production is significantly increased.In order to address the above problem, technical scheme provided by the utility model is that a kind of fireworks safety firing cable comprises the parcel sleeve pipe that cotton braid forms, described sleeve pipe is provided with waterproof layer outward, and the medicine core of parcel is made up of the cotton that attaches the firing line medicine in the described sleeve pipe.

As of the present utility model a kind of preferred, the described quantity that attaches the cotton of firing line medicine is one.

The making method of described fireworks safety firing cable, form by following steps in regular turn:

Step 1, firing line medication preparation:

1), selects the medicine proportioning: get rid of the impurity in the medicine and take by weighing medicine in proportion;

2), mixing screen medicine: powdered drug is mixed;

3), add an amount of organic solvent and stir, make medicine become heavy-gravity fluid drug pulpous state attitude, put in storage standby;

Step 2, on wiring machine with yarn braiding parcel firing line medicine:

The firing line medicine that last step the makes making machine drug bucket of packing into, at least one cotton yarn introduced the wiring machine drug bucket, cotton yarn attaches heavy-gravity fluid drug slurry and draws from the drug-leaking hole of drug bucket in drug bucket, wrap up densely with many cotton braid packaged tubes and to the cotton yarn that attaches the medicine slurry, this process is continuously carried out, and the safety firing cable work in-process of formation are through the winding mechanism coiled coil of wire of igniting.

Step 3, with the safety firing cable work in-process made in the above-mentioned steps through japanning, the air-dry finished product that makes.

The safety firing cable that adopts technical solutions of the utility model to make has following advantage:

1, quality product improves, and stops the generation of resolving medicine, few medicine, leaking the medicine phenomenon;

2, reduced the higher technical process of a plurality of danger in the firing line medicine processing, stopped the drawback that drug dust intersperses among the production place in the cotton yarn parcel, production security has had the raising of matter; And no dust pollution in produce using, avoided producers injured by occupational illness such as silicosis.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
