[0002] A pull-bomb is a kind of fireworks. Its operation is very simple. It doesn't need to be ignited. Just pull the pull rope on the surface of the tail of the pull-bomb shell with your hand. Along with a "pop" sound, the colored ribbon will immediately rush into the sky, forming beautiful colored flowers. The pull-bomb has no smoke, no smell and no sparks, and is an essential good for festive places such as weddings, celebrations and dances. The assembly of the small pull-bomb includes processes such as the fixation of the pull-rope type ignition element (commonly known as the striker in the industry) and the filling of the colored ribbon. One end of the striker passes through the shell body and the other end is fixed on the surface of the tail of the pull-bomb shell. With the replacement of the assembled shell by the integrally formed shell with lower cost, manual production or existing automatic assembly equipment is no longer suitable, not only with low production efficiency, but also unable to guarantee the assembly quality.

[0003] Therefore, there is an urgent need for a hand-held small pull-bomb assembly production line that can realize automated flow operation, has high assembly quality and high efficiency to overcome the above problems, so as to improve the product quality while improving the production efficiency.

The paper cutting device includes a cutting knife 138, a paper feeding mechanism 139, and an acrylic tube 140 for loading the colored paper tape 143. The cutting knife is arranged below the paper feeding mechanism. The cutting knife is arranged at the output end of a cylinder 142, and includes an upper tool and a lower tool. The colored tape can be cut during the telescopic process of the cylinder. In this embodiment, the paper feeding mechanism adopts the structure of a circular belt feeder to cut the fed paper tape. The paper plugging device includes a funnel 141. The upper opening of the funnel is facing the colored paper tape, and the lower opening is facing the pull-tab shell in the carrier. The colored paper loading machine in this embodiment includes three paper plugging devices and paper cutting devices arranged in parallel, and simultaneously loads the colored paper tapes into the three pull-tab shells assembled with the bottom covers.

[0052] The top cover assembling machine in this embodiment has the same structure as the bottom cover assembling machine, and is used for assembling the top cover of the pull-tab shell filled with the paper tape.

[0053] See Figure 19, for the small firecracker products produced by the production line of this embodiment, the firecracker shell 12, the bullet 13, the top cover 14, the bottom cover 15, and the ribbon are assembled together by the production line of this embodiment. The specific process steps include:

[0054] First step, the firecracker shell is poured into the hopper of the baffle belt elevator, lifted and fed into the vibrating bowl. The vibrating bowl has a one-out-three output, and after passing through the straight vibrating track, it enters the conveying guide rail;

[0055] Second step, the conveying guide rail moves forward 3 workstations and enters the drilling machine; the motor drives the drill bit to rotate, and at the same time the cylinder presses down to polish the burrs at the tail of the firecracker shell cylinder. After polishing the burrs at the tail of the firecracker shell cylinder, the conveying guide rail moves forward 3 workstations and enters the bullet assembly machine;

[0056] Third step, the bullet falls into the nylon strip with grooves, is sent forward 3 workstations through the bullet conveyor belt, and enters the first blowing station. The first blowing station blows air to make the bullet enter the two side air pipes;

[0057] The air pipe is connected to the front end air outlet (the air pipe is not shown), the cylinder presses down, the air outlet is inserted into the firecracker shell, and after secondary blowing, the bullet is blown into the firecracker shell;

[0058] Fourth step, the conveying guide rail moves forward 3 workstations and enters the bullet folding-up mechanism and the gold ribbon winding mechanism:

[0059] First, the finger cylinder grabs the bullet wire, and through the left-up-right movement of the bullet folding-up mechanism, the bullet wire is folded upward; then the cylinder of the firecracker shell pressing-down mechanism presses down, and the cylinder of the gold ribbon winding mechanism sends it forward, so that the gold ribbon is wound around the tail of the firecracker shell; the conveying guide rail continues to move forward, passes through the gold ribbon finishing mechanism, and makes the gold ribbon completely wrap the tail cylinder 16 of the firecracker;

[0060] Fifth step, an appropriate amount of bottom cover cardboard is placed on the elevator by the bottom cover assembly machine; the elevator is lifted to an appropriate height; the suction cup comes down, sucks up a piece of bottom cover cardboard, and is translated to a fixed position through the action of the cylinder; the bottom cover cardboard is placed on the cardboard bottom plate; the bottom cover is pressed into the firecracker shell through the stamping mechanism, and the bottom cover loading is completed;

[0061] Sixth step, the colored paper is cut. The whole colored paper is cut into pieces of ribbons and put into the firecracker shell. The colored paper is inserted into the acrylic tube. The circular belt feeding mechanism sends the colored paper to the cutter. The motor makes the circular cutter rotate. The cutter is pushed by the cylinder to cut the colored paper into pieces of ribbons; the ribbons pass through the funnel and fall into the carrier carrying the firecracker shell; the next step is the top cover loading, and the principle of the top cover loading is the same as that of the bottom cover loading;

[0062] In the seventh step, the assembled finished product falls from the tail of the conveying guide rail and drops into another baffle belt elevator. After being lifted by the elevator, it drops into a vibrating bowl, and the vibrating bowl feeds it forward into a labeling machine to complete the final labeling step of the cracker assembly production line.

[0063] The effect of this embodiment is that through the cooperation of each mechanism, the integrated cracker shell is successively assembled with bullets, bottom covers, ribbons, and top covers. The structure is simple, time-saving, efficient, convenient and practical, meeting the requirements for large-scale production of crackers with integrated cracker shells.
