Description

[0002] Fireworks, also known as firecrackers, fireworks, fireworks, and firecrackers, are entertainment products made of fireworks powder that produce sound and light. Rocket fireworks will ascend when fired, and a stabilizing rod is provided on the product to support the main body. When processing the product, the stabilizing rod and the main body containing gunpowder need to be bound together by tape. Existing rocket fireworks production mostly uses manual binding, which is low in efficiency and cannot guarantee the flatness of the main body and the stabilizing rod.

[0003] Therefore, Chinese patent CN107270779B discloses a tape binding device for the cylinder and stabilizing rod of rocket fireworks, which can automatically complete the tape binding and connection of the cylinder and stabilizing rod of rocket fireworks. The connection between the cylinder and stabilizing rod is flat and firm. The device is coordinated, reliable, efficient, accurate, and greatly improves production efficiency and effectively guarantees processing quality. It drives the tape to wrap around the stabilizing rod and cylinder through the revolution and rotation of the tape roll, completing the binding of the workpiece.

[0004] However, as the tape is used, the diameter of the tape roll gradually decreases, so the rotation speed and revolution speed of the tape roll need to be adapted. Otherwise, the tape will hang and stick to each other. After winding is completed, the tape at the end of the workpiece is in a raised state when it is cut by the upper or lower cutter, and it is not stuck to the workpiece.
