Description

Technical Field

[0001] This utility model relates to the field of fireworks production technology, and in particular to a paper shell drying device. Background Technology

[0002] Fireworks are pyrotechnic entertainment products that use gunpowder to produce sound, light, and color effects through combustion or explosion for viewing. In the production process, paper is rolled into cylindrical firework shells by machinery. These cylindrical shells are then dried to ensure their stability and quality. The drying process is crucial for preventing the shells from getting damp, increasing their strength, and ensuring the safety of the fireworks.

[0003] Current firework paper drying equipment typically uses a conveyor belt to transport the finished cylindrical firework paper to the drying area. The drying equipment then heats the paper on the conveyor belt and uses a fan to drive airflow within the drying equipment, causing the moisture inside the paper to evaporate. This reduces the moisture content of the paper and improves its stability and strength. However, the feeding and discharging areas of existing devices are both open, which easily leads to heat loss and high waste.

Isolation frames are symmetrically connected front and back on the upper left and lower right sides of the drying oven. Grooved wheels are rotatably connected between adjacent isolation frames, and transmission assemblies are connected between the grooved wheels and the conveyor belt.

[0008] Optionally, the isolation mechanism also includes a guide platform, which is connected to the right side of the drying oven and is located between the conveyor belt and the grooved wheel at the lower right.
