Problems solved by technology

The disadvantages of this type of equipment are: first, the blockage of the injection hole is more serious, and the work reliability is lower; second, the moving back and forth of the slurry plate reduces the production speed, and there is an allowable slurry plate between the injector and the cylinder cake. Due to the distance between them, the two need to be close during pouring, which also leads to a decrease in production efficiency; third, the slurry in the open slurry tray is dry and solidified in contact with the air, resulting in serious loss of slurry

Embodiment 1

[0017] Embodiment 1: see attached Figure 1-3 , reflecting a specific structure of the present invention, the drug injection device for fireworks and firecrackers includes a cavity 1 loaded with drug slurry, and 61 casing tubes 3 are installed on the cavity 1 in a manner penetrating through the cavity 1. The quantity of pipe 3 is equal to the firecracker fireworks tube (not shown in the figure) quantity of lower tube cake, and sleeve pipe 3 positions are corresponding to the position of the firecracker fireworks tube of lower tube cake.

[0018] The side wall of the sleeve 3 located inside the cavity 1 is provided with an opening 5 through which the drug slurry enters the inner cavity of the sleeve 3 ; the opening 5 is a partial rectangular window on the side wall of the sleeve 3 .

[0019] The inner cavity of the casing 3 is nested with a sliding rod 4, and the top of the sliding rod 4 is fixed on the base body 6, and the base body 6 is driven by a driving mechanism (not show...

Embodiment 2

[0020] Embodiment 2: see attached Figure 4 , the difference from Embodiment 1 is that: the opening 15 is an annular fault on the casing 13, at this time the casing 13 is divided into two mutually independent parts, and the annular fault can be formed after cutting a whole section of the casing 13. It is formed on the side wall of the casing 13; it can also be formed by making the two parts separately. Part of the casing 13 below the annular fault is fixed by the bottom plate of the cavity 11 . The bottom end of the slide bar 14 is a needle-shaped structure 17 , and the slurry cannot condense on the bottom end surface of the slide bar 17 . The remaining parts of Embodiment 2 are similar to Embodiment 1 and will not be repeated here.

Abstract

The invention discloses an explosive filling device for fireworks and crackers. A plurality of sleeves are arranged on a cavity for loading explosive slurry in a mode of penetrating through the cavity; side walls of the sleeves inside the cavity are provided with openings for introducing the explosive slurry into inner cavities of the sleeves; slide rods are embedded into the inner cavities of the sleeves; the top ends of the slide rods are connected with a drive mechanism so as to move up and down in the sleeves; descending end points at the bottom ends of the slide rods can be parallel to bottom end openings of the sleeves or extend out of the bottom end openings of the sleeves; ascending end points at the bottom ends of the slide rods are higher than the openings. The device is high in working reliability, accurate, uniform and controllable in filling amount, high in production efficiency and low in production loss.

Description

technical field [0001] The invention relates to a production and processing equipment for fireworks and firecrackers, in particular to a drug filling device for fireworks and firecrackers. Background technique [0002] Drug infusion, commonly known as dosing, refers to the filling of slurry-like pyrotechnic powder or glue material into the inner cavity of the fireworks tube or around the lead wire at the end of the firecracker during the production process of fireworks and firecrackers. Such as rubbing gunpowder, pointing tail medicine, pointing gunpowder, dispensing, etc. At the same time, the fireworks and firecracker tubes to be processed are aggregates formed by a plurality of tubes juxtaposed and bundled together, called tube cakes. The traditional manual dispensing process is completed one by one. For example, a tube cake is composed of 19 fireworks and firecracker tubes, and it is necessary to manually dispense medicine 19 times. The medicine dispensing machinery an...
