Processing needed for the sparkler production:

1. Wire Cutting and Straightening: 

   The initial step in creating sparklers, whether DIY or industrial, begins with a wire cutting and straightening machine. This machine takes a lump of iron wire and transforms it into individual pieces, each one destined to become the core of a sparkler.

   The machine works by pulling the wire straight, eliminating any bends or kinks that could affect the final product’s performance. It then cuts the wire into specific lengths, typically around 17 cm to 30 cm for handheld sparklers. When planning to make your own sparklers, consider the size of the finished sparkler you want. The length of the wire will determine how long the sparkler will burn.

2. Resin Crushing: 

   In the sparkler production process, crushing the resin is an essential step. The resin, a vital ingredient of the homemade sparkler mixture, is crushed using a resin crusher. This machine grinds down the resin into a fine powder, making it easier to mix with other dry chemicals. The smooth texture of the crushed resin ensures a uniform blend in the subsequent mixing process. This process is critical as it determines how well the sparkler burns and sparks when ignited.

   In addition to resin, other components like strontium nitrate and aluminum powder are also crushed for the sparkler mixture. Strontium nitrate is used to give the sparkler its vibrant red flame, while aluminum powder burns to create brilliant white sparks. The crushing process ensures that these components are fine enough to burn smoothly and completely, creating a spectacular pyrotechnic display.

3. Powder Mixing: 

   After the resin and other components have been crushed, they are mixed together to form the sparkler’s explosive part. This process involves a powder mixing machine, which blends the crushed resin, strontium nitrate, aluminum powder, and other chemicals into a consistent mixture. Water is added to this dry chemical mixture to create a slurry.

   This mixture is not just a simple paste; it’s a carefully balanced concoction of chemicals designed to produce a dazzling array of sparks. Additional ingredients like potassium and dextrin may be added to the mixture to improve the sparkler’s performance. Potassium helps to regulate the burning rate of the sparkler, while dextrin acts as a binder, holding the slurry together and adhering it to the wire.

   The mixture forms the heart of the sparkler, the source of its characteristic sparks. When the sparkler is ignited, the heat from the flame reacts with the chemicals in the mixture, resulting in a stunning firework display. The mixture needs to be thoroughly mixed to ensure an even distribution of chemicals, which contributes to a consistent and prolonged spark effect.

4. Wire Planting: 

   The wire planting stage is a crucial step in the process of making sparklers. This is where the straightened and cut wires are prepared for the subsequent coating process. Utilizing a wire planting machine, the wires are inserted into small holes on a plastic board – a task that once required meticulous manual labor.

   This machine can plant up to 480 wires at once, which significantly enhances efficiency, making it an ideal solution for industrial-scale sparkler production. The wires, resembling bamboo skewers at this point, are arranged systematically on the board, leaving a few inches at the end of each wire. These ends will serve as handles, allowing the finished sparklers to be safely held when ignited.

5. Dipping Wire: 

   Dipping Wire: The next stage in the sparkler production process involves dipping the wires into a chemical mixture. Workers take the plastic board, now bristling with straight pieces of wire, and immerse it into a storage tank filled with the sparkler mixture.

   This mixture is a carefully formulated blend of dry chemicals, including potassium nitrate and xxxx. These components are responsible for the sparks that will eventually burst forth from the finished sparkler. Depending on the desired effects of the sparkler, other chemicals such as aluminum or titanium flakes might be added to the compound.

   The wires are left to soak in the mixture, allowing the mixture to thoroughly coat each piece. This coating process is crucial as it determines how the sparkler will burn and ignite. A thick, even coating ensures a steady, prolonged burn, while an uneven or insufficient coating could lead to the sparkler burning out prematurely or even exploding.

   During the dipping process, some of the compound may drip off the wires. To prevent waste and maintain a clean working environment, a material collector is placed underneath to collect any dripping powder liquid.

   Once the wires are fully coated, they are removed from the compound and left to dry. It’s important to let them dry completely before proceeding to the next step. This can be done by placing the wires on a drying rack. Remember to check your local laws regarding pyrotechnics manufacture and always exercise extreme caution during this process.

6. Heating Room: 

   Heating Room and Drying Process: Once the wires are thoroughly coated with the chemical slurry, they are transferred to a specialized heating room for drying. This room is equipped with an advanced heating system, which includes a heater, dehumidifier, and controller, to maintain optimal drying conditions.

   The coated sparkler skewers, which now resemble bamboo sticks, are arranged on a drying rack in the heating room. Proper spacing is crucial at this stage to ensure even heat distribution and prevent the sparklers from sticking together. Each sparkler is securely placed on the rack, leaving enough room for air circulation.

   It’s essential to let the sparklers dry completely before proceeding to the next step. The drying process typically takes about 6-8 hours, but this can vary depending on the specific conditions in the heating room, such as temperature and humidity levels.

   The heating room is maintained at a consistent temperature of approximately 60 °C. This temperature is carefully controlled by the system’s heater and monitored with the controller. If the temperature drops or rises beyond the desired range, the heater or dehumidifier will adjust accordingly to maintain the optimal drying environment.

   During this drying period, the coated wires transform into finished sparklers. The chemical slurry hardens onto the wires, creating a solid, combustible coating that will catch fire and produce beautiful sparks when ignited.

   Remember that safety is paramount during this process. The heating room should be well-ventilated to prevent the buildup of potentially hazardous fumes. Also, the room should be kept free of flammable materials to minimize the risk of accidental fires.

7. Repeating Dipping and Heating: To ensure sufficient thickness of the chemical coating on the wires, steps 5 and 6 are repeated twice.

8. Remove wires from Plastic Boards: Once the wires are thoroughly dried and coated, they are removed from the plastic boards. This step prepares the sparklers for packaging.

9. Packing with Plastic Bag: To ensure that your sparklers are safely packaged, it’s advisable to use an automatic bag packing machine. This machine is not only used for packing sparklers, but can also handle a variety of other items such as noodles, one-time use tableware, hotel daily supplies, towers, tissues, needles, sausages, cookies, sticks, and any other long-shaped items.

10. Packing with Paper Carton:
    Finally, Packing with Paper Carton.

    This is where the automatic carton forming inserting & sealing machine comes in. This machine is not just good for packing fireworks like your sparklers, but also other items such as electronics.

    The machine is able to complete carton forming, carton inserting, carton folding, and carton sealing, making it a one-stop solution for your packaging needs. It is designed for individual operation but is also capable of connecting with other machines to form a complete packaging line.

What is a sparkler powder mixer?

A sparkler powder mixer is an industrial machine used to mix the chemical powders and compounds needed to make sparklers for fireworks. Sparklers contain an oxidizer powder, a fuel powder and other additives that are carefully blended together in the proper proportions to create the colorful sparks when ignited.

The powder mixer discussed in this patent consists of a stirring barrel, installation plates, a stirring mechanism and connecting components. The stirring mechanism includes rectangular plates, rotation shafts, stirring blades and gear parts. When the powder materials are placed into the barrel, the stirring blades rotate and agitate the powders through the rotation of the shafts.

This stirring and blending process ensures an even and uniform mixture of the sparkler powders, which is critical for achieving consistent performance and quality of the finished sparklers. The proper mixing of the raw materials gives the sparklers their brightness, color intensity and duration of sparks upon ignition.

The main function of the powder mixer is to homogenize the oxidizer, fuel and additive powders into a uniform mixture that yields sparklers with reproducible effects. The stirring and agitating action creates a homogeneous distribution of particles and prevents clumping of the powders.
