Description

Technical Field

[0001] The utility model relates to the technical field of fireworks edge-sealing dies, in particular to a correctable device for fireworks edge-sealing dies. Background Art

[0002] Fireworks are traditional pyrotechnic entertainment products, and edge-sealing technology is crucial in their production process. Edge sealing not only affects the aesthetic appearance of fireworks, but is also directly related to the safety and stability of fireworks during use. Traditional fireworks edge sealing is mostly done manually or semi-automatically, which is not only inefficient, but also difficult to ensure edge sealing quality, and prone to problems such as air leakage and cracking. With the development of science and technology, modern fireworks edge sealing technology has gradually adopted automated and mechanized means, and through precise control of edge sealing force and temperature, efficient and high-quality edge sealing effects have been achieved. In addition, the application of new edge-sealing materials has further improved the sealing and durability of fireworks, significantly improving the ornamental value and safety of fireworks.

[0003] The die is a core tool in the edge-banding process for fireworks, and its design and manufacturing quality are directly related to edge-banding quality. Firework edge-banding dies typically consist of two parts: an upper die and a lower die. Driven by a hydraulic cylinder or mechanical force, these two parts work closely together to complete the edge-banding of the fireworks barrel. The upper die applies pressure, tightly fitting the edge-banding material to the edge of the fireworks barrel; the lower die provides support and positioning, ensuring accurate edge-banding. Through precise die design and appropriate material selection, these two parts achieve efficient and precise edge-banding of fireworks barrels.
