Although mechanical equipment has been introduced in some links, the core process is still highly dependent on manual labor, leading to the following problems:

[0003] The efficiency is low, key parameters such as charging accuracy and lead position adjustment rely on workers' experience, and the training cycle is long. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a firecracker tube insertion mechanism, a fireworks and firecracker production device and a fireworks and firecracker production method, which are used to replace manual production, improve production accuracy, and enhance assembly capacity.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a firecracker tube insertion mechanism, characterized in that it is used to put the firecracker tube on the lead on the fixture, and the firecracker tube insertion equipment includes a lower pressure plate constituting a pre-shaping structure, a shaping extrusion part, and a plurality of retaining structures extending from the lower pressure plate, and the shaping extrusion part is provided with at least one group, and the shaping extrusion parts in the group are relatively arranged in a form so that the firecracker tube extends in two fixed directions after being subjected to relative extrusion pressure, so that the retaining structure on the lower pressure plate and the tube gap in the firecracker tube are opposite to each other, and the retaining structure is inserted in the tube gap and contacts with the tube wall to clamp the firecracker tube.

The advantage is that the close contact formed by the deformation between the tubes can keep the whole body at a certain flatness, reducing the difficulty of assembly with the jig in the later stage. At the same time, this way of simulating a worker grabbing a firecracker tube will not cause tortuosity and deformation to the outermost tube body of the firecracker tube. In order to achieve this effect, at least one group of shaping extrusion parts and a retaining structure extending from the lower pressing part are used. When the shaping extrusion parts are relatively set, the firecracker tube is extended in two fixed directions to ensure that the gap formed by the mutual extrusion between the tubes forms a mutually coordinated state with all the retaining structures.

A method for producing fireworks and firecrackers, characterized in that: The following steps are involved: S1, the transport mechanism simultaneously clamps the empty tray jig on the first rotating platform and the jig on the lead wire machine, lifts the jig to form a dislocation effect between the jig and the positioning structure on the first rotating platform, and then swaps the positions of the two jigs while rotating; S2, the first rotating platform drives the fixture with the lead wire inserted to the working range of the firecracker tube insertion mechanism. At the same time, the firecracker tube insertion mechanism has pushed the firecracker tube to move towards the feeding hole. During the movement, the entire firecracker tube will be tightened to a certain extent by the extrusion block and the plastic spring, and under the action of the extrusion block and the plastic spring, the firecracker tube is suspended above the feeding hole; S3, when the firecracker barrel is assembled with the jig, the lower pressing plate presses the firecracker barrel to move onto the jig; S4, the first rotating platform drives the fixture equipped with the firecracker tube to move to the mud injection mechanism, and the mud injection mechanism injects mud into the firecracker tube; S5, the mud pressing cylinder pushes the mud pressing plate to move toward the second channel, so that the mud pressing column moves into the second channel, exerting pressure on the mud in the second channel; S6, remove the firecracker tube from the fixture and transfer the firecracker tube to other processes.
