Rolling device for longitudinal and transverse composite firework paper tubes

Abstract

The invention discloses a rolling device for longitudinal and transverse composite firework paper tubes, crisscrossed composite paper is obtained and rolled and formed through staggered and superposed glue compounding of longitudinal and transverse paper feeding, the strength of the paper tubes is effectively improved on the premise that the tube wall thickness and the paper consumption of the paper tubes are not increased, and the high-load requirement is effectively met. Meanwhile, the paper tube has no folds and is not easy to bend; the sealing quality can be ensured without wetting the seal with water, and the drying period is short; label preprinting is facilitated; the high-speed processing of the kraft paper tube can be realized, the problems of difficulty in sealing, insufficient strength and high cost of the traditional process paper tube are solved, the production cost of fireworks and firecrackers is reduced, and the safety of fireworks during setting off is ensured.
