Description

Technical Field

[0001] This utility model relates to the field of firecracker production technology, and in particular to a firecracker disc transmission device for firecracker production. Background Technology

[0002] Firework trays are load-bearing devices used to orderly fix and arrange firework powder charges. They are usually made of high-strength materials with flame-retardant properties, such as special composite fibers or metal skeletons with fireproof coatings. Their structure is mostly three-dimensional mesh or layered frame type, formed into a stable shape through precision weaving or injection molding processes. This ensures that the firework charges maintain a fixed distance during transportation and storage to prevent collisions and dangers, and allows them to be detonated one by one in the designed sequence when set off. Some firework trays also integrate heat insulation layers and buffer structures to reduce safety risks in case of accidents. They are also compatible with automated production lines for efficient assembly and are a typical product that combines traditional firecracker craftsmanship with modern safety technology.

[0003] During the subsequent processing of firecracker discs, they need to be transported to the next process via a conveyor device for further processing.

[0004] Patent document CN218200350U discloses an automatic conveying device for fireworks and firecracker paper tubes. This automatic conveying device includes: a mounting frame; a transport device disposed inside the mounting frame; and two threaded holes respectively disposed on the front and rear sides of the outer surface of the mounting frame. An adjusting device, including a threaded rod, is engaged internally within the threaded holes. This utility model provides an automatic conveying device for fireworks and firecracker paper tubes. By rotating the threaded rod and engaging the threaded holes, a limiting device is moved within the conveying trough, thereby limiting the movement of fireworks and firecracker paper tubes of different lengths. This device has a simple structure, strong practicality, and can accurately control the position of the limiting device, adapting to and restricting paper tubes of different lengths. It prevents the paper tubes from shifting or deviating on the conveyor belt, maintaining the neatness of the paper tubes during transport, and facilitating subsequent processing.

[0005] As in the prior art of the aforementioned patent, the device adjusts the limiting devices on both sides during the transportation of firecracker trays to clamp the firecracker tray in the middle neatly, so that the firecracker trays can be transported in an orderly manner. However, the size of the firecracker tray is limited, and it is not necessary to use a large area conveyor belt. This not only makes maintenance more troublesome, but the device itself will also occupy a large area. Utility Model Content
