Description

Technical Field

[0001] This utility model belongs to the field of fireworks manufacturing equipment technology, specifically relating to a fireworks paper stamping and filling equipment. Background Technology

[0002] Paper tube fireworks are a typical type of fireworks product, widely used during various festivals. The paper filling in paper tube fireworks plays a crucial role in separating the launching gunpowder from the inner tube effect components, directly affecting the final effect of the fireworks; in the fireworks manufacturing process, the stamping and filling of paper is a key step. Currently, existing fireworks paper filling technology has many shortcomings.

[0003] Current technology relies heavily on manual operation, requiring workers to manually cut and fill paper sheets, which is labor-intensive.

[0004] Secondly, the level of automation is low, with some equipment only able to complete a single process, making it difficult to achieve full-process automation. Furthermore, changing production methods is difficult; when different specifications of fireworks paper need to be produced, equipment adjustments are complex, time-consuming, and material utilization is low, generating a significant amount of waste during the paper cutting process.

[0044] The installation location and working principle of this embodiment are as follows:

[0045] The paper roll feeder 1 is installed on the outside of the frame 5 to facilitate the feeding of paper rolls. The feeding roller 12 is installed inside the frame 5 and connected to the paper roll feeder 15 to ensure smooth paper roll conveying. The stamping and filling mechanism 2 is installed above the frame 5, containing the filling cylinder 22 and the stamping cylinder 21 to provide power for stamping.

In addition, the rubber positioning pin 217 is embedded in the gap of the cartridge 31, and the positioning pin and the filling cap 219 are pressed down and inserted into the positioning hole pre-drilled by the punch 210, accurately pressing the paper sheet into the inside of the cartridge 31.

[0048] The limiting tray 32 of the tooling tray 3 is installed on the tooling plate 33; the tooling plate 33 is provided with pin holes around its perimeter, which are used to achieve limiting by cooperating with the pins of the lifting mechanism 43.

[0049] When the conveyor lifting line 4 is working, the blocking mechanism 42 is installed at a specific position on the conveyor line 41, limiting the tooling pallet 3 to be directly below the reserved hole in the bottom plate 212 of the stamping and filling mechanism 2.
