In order to ensure that the tail powder is reliably ignited, a small amount of military nitrate or other combustion-supporting pyrotechnic compositions, called nitrate spraying, are sprayed on the tail powder dripped on the inner cylinder.
In actual production, a plurality of inner cylinders are bundled into an aggregate with a hexagonal shape and the like, which is called a cylinder cake, and the cylinder cake is taken as a minimum processing unit, and is not processed one by one, no matter the cylinder cake is scattered with the tail.
The tool for dispensing the tail is a tail dispensing die, such as a material injection mechanism capable of simultaneously dispensing tail medicines for a whole-cake gun barrel, disclosed in Chinese patent publication No. CN 204718506U. And finishing the tail-pointing operation of the inner barrel of the whole barrel cake through a tail-pointing die-a material-homogenizing disc.
The nitrate spraying tool is a nitrate spraying die, and the falling of materials is controlled mainly through the switching of the upper through holes and the lower through holes between a dislocation state and a coupling (superposition) state. The nitrate spraying mold has a plurality of different concrete structures with two-layer structures and three-layer structures.
A firework charging machine with a two-layer structure as disclosed in Chinese patent publication No. CN 2233075Y;
three-layer structure of 'an automatic filling device for firework pyrotechnic composition of combination' disclosed in Chinese patent publication No. CN 107356160A: a bottom plate of the pyrotechnic charge storage hopper is provided with a plurality of upper through holes; a lower plate is fixedly connected below the bottom plate, a plurality of lower through holes are formed in the lower plate corresponding to the upper through holes, the lower through holes and the upper through holes are arranged in a staggered mode, and the number and the positions of the upper through holes are corresponding to those of the inner cylinders of the lower cylinder cake; a middle sliding plate is arranged in the cavity between the bottom plate and the lower plate, and a plurality of middle through holes are arranged on the middle sliding plate corresponding to the upper through holes; the cylinder cake to be processed is placed at a proper position below the lower plate, the middle sliding plate is shifted, so that the middle through hole is communicated with the upper through hole, and the pyrotechnic composition in the pyrotechnic composition storage hopper falls into the middle through hole through the upper through hole; the middle through hole is communicated with the lower through hole by the middle sliding plate in the reverse movement, and pyrotechnic composition in the middle through hole passes through the inner barrel of the lower through hole.

(3) Seventh cylinder 30 steps down, drives receiving plate 47 to step down, and feed plate 46 to step up.
The above-described flow is repeatedly run until the receiving plate 47 descends to the bottommost end to contact the driving mechanical control valve 27, and the mechanical control valve 27 closes the compressed air source, so that the start switch 1 cannot perform the start function.
After the stacked cylindrical cakes on the material receiving plate 47 are manually collected, the manual control valve 28 is pressed down, the eighth cylinder 29 acts to drive the material feeding plate 46 to descend and reset, and meanwhile, the material feeding plate 46 drives the second conveyor belt 50 to reversely rotate and reset, so that the material receiving plate 47 is driven to ascend and reset.
The feed plate 46 is lowered and reset to contact the drive mechanical control valve 26, and the mechanical control valve 26 opens the compressed air source, so that the start switch 1 resumes the start action.
The device is restored to the initial state, and the above procedure can be repeated.
From the above, the mechanical control valves of the sixth, seventh, eighth and ninth cylinders can be driven by the contact of the cylinder cake, the receiving plate, the feeding plate or other linkage pieces, so that the corresponding cylinders act timely.
The above is the process of the automatic operation of the equipment.
The equipment is also provided with a manual/automatic change-over switch 37, when the equipment is ready for operation, the equipment is switched to a manual mode for equipment debugging preparation, and at the moment, the height of the die is adjusted to correspond to a product through the die-lifting and die-pressing switch 38; the tail medicine is pressurized by a tail medicine manual pressurizing switch 39.
The device is also provided with a barrel lifting/pressing switch 40 and a barrel lifting cylinder 41 for adjusting the height of the tail medicine storage container 33 so as to facilitate the work of adding and cleaning the tail medicine.
The foregoing implementations are merely illustrative of the present utility model and are not to be construed as limiting thereof. The utility model has a plurality of alternatives or variants known in the technical field, and all fall into the protection scope of the utility model without departing from the essential meaning of the utility model.
