[0002] Fireworks tubes, also known as wedding salutes, fireworks, ceremonial flowers or colorful fireworks, are handheld fireworks that are released on festive occasions such as business openings and weddings. They are usually wrapped in gold or red outer wrapping paper. Their main function is to release compressed air by rotating or pressing a button to generate an explosive impact force, which will rush the colorful strips, sequins or petals filled in the paper tube into the air, thereby creating a festive effect and increasing the atmosphere of the event.

[0003] The labeling machine (also known as the labeling machine) glues and cuts the rolled wrapping paper or label paper and then pastes it on the corresponding products. However, the labeling machine equipment currently on the market only cuts the outer wrapping paper of the fireworks tube and pastes it on the corresponding products after it is cut. This makes it difficult for the outer wrapping paper of the fireworks cannon, which releases compressed air by rotation, to be torn apart by twisting during rotation, making the rotation operation difficult, time-consuming and labor-intensive. Summary of the invention
