Description

Technical Field

[0001] The utility model relates to the technical field of firecracker manufacturing, in particular to a firecracker winding device. Background Art

[0002] Firecrackers, also known as firecrackers, refer to products that explode when ignited and can produce effects such as popping sounds and flashes, and are mainly auditory effects. During the production process of strip firecrackers, the firecrackers need to be rolled into discs and then packaged for sale.

[0003] Some equipment on the market can generally install the mounting plate by inserting the slider into the slide groove. After pulling up the connecting plate, the limit of the mounting plate can be cancelled for disassembly, thereby facilitating the unloading of the rolled firecrackers and facilitating the rapid production and processing of firecrackers. By providing a pressure roller and a first spring, the firecrackers can be rolled more tightly, which is beneficial to improve the flatness and tightness of the firecrackers after rolling up and improve the rolling effect.

[0004] However, during actual use of the above-mentioned device, the strip firecrackers will contact with the outer surface of the mounting plate and generate friction, which will cause the strip firecrackers to be damaged due to excessive friction when being rolled up; in view of this, we propose a firecracker rolling device.
