[0034] like Figure 1-Figure 8As shown, the present invention discloses a fireworks propellant canning machine, comprising a frame 1, a quantitative charging device 2 installed on the frame 1, and a conveying device. The frame 1 is grounded, the quantitative charging device 2 is detachably installed by bolts, the conveying device is a belt conveyor 22 arranged under a bottom plate 6, the belt conveyor 22 conveys a fireworks tube 7 to the bottom of the quantitative charging device 2 to load stuff, the fireworks tube 7 in this embodiment is a square column structure with parallel sides, the quantitative charging device 2 comprises a hopper 3 and a panel 4, a quantitative plate 5 and a bottom plate 6 which are sequentially stacked and installed from top to bottom, a tuning fork sensor 36 for detecting the amount of propellant is installed in the hopper 3, the quantitative plate 5, the quantitative plate 5 and the bottom plate 6 are made of antistatic plastic plates, the panel 4 is installed at the lower side of the bottom outlet of the hopper 3, the propellant in the hopper 3 will fall onto the panel 4 under the action of gravity, the bottom plate 6 is provided with a bottom plate through hole 8 corresponding to the charge hole of the fireworks tube 7 on the conveying device, the quantitative plate 5 is provided with a quantitative hole 9 corresponding to the bottom plate through hole 8, the panel 4 The panel through hole 10 corresponding to the quantitative hole 9 is provided on the top, and the quantitative plate 5 is slidably connected between the panel 4 and the bottom plate 6 to alternately connect the bottom plate through hole 8 and the panel through hole 10. The panel through hole 10 and the bottom plate through hole 8 are staggered. Specifically, the quantitative plate 5 is driven to extend and retract by the quantitative plate driving cylinder 37. When the piston rod of the quantitative plate driving cylinder 37 is extended, the panel through hole 10 and the quantitative hole 9 are aligned, and the upper end of the bottom plate through hole 8 is closed by the lower side of the quantitative hole 9, so that the medicine in the hopper 3 enters the quantitative hole 9. Then, the piston rod of the quantitative plate driving cylinder 37 retracts, the bottom plate through hole 8 is aligned with the quantitative hole 9, and the upper end of the quantitative hole 9 is closed by the lower side of the panel 4, and the propellant in the panel through hole 10 cannot fall. At this time, the propellant in the quantitative hole 9 falls and enters the charging hole of the firework tube 7 through the bottom plate through hole 8, thereby realizing the quantitative charging of the firework tube 7, wherein the inner diameters of the quantitative hole 9, the panel through hole 10 and the bottom plate through hole 8 are controlled to be smaller than the inner diameter of the charging hole on the firework tube 7 to prevent the propellant from escaping.

[0035] In this embodiment, in order to quickly transfer the propellant on the opposite surfaces of the panel 4 and the quantitative plate 5, and the quantitative plate 5 and the bottom plate 6, and thereby prevent the repeated extrusion and friction of the propellant on the opposite surfaces of the panel 4 and the quantitative plate 5, and the quantitative plate 5 and the bottom plate 6, a material guide cavity 11 is provided on one side of the bottom plate 6, and a panel material guide groove 12 having one end connected to the material guide cavity 11 and arranged between the panel through holes 10 is provided on the surface opposite to the panel 4 and the quantitative plate 5, and a quantitative plate material guide groove 13 having one end connected to the material guide cavity 11 and arranged between the quantitative holes 9 is provided on the surface opposite to the quantitative plate 5 and the bottom plate 6.

[0037] In this embodiment, fireworks tube sensing probes 23 and fireworks tube limiting mechanisms are provided on both sides of the belt conveyor 22. The fireworks tube sensing probes 23 can be proximity switches or infrared sensing probes. The fireworks tube limiting mechanisms include limiting telescopic drive components 24 and limiting plates 25 installed at the telescopic ends of the limiting telescopic drive components 24 (in this embodiment, unless otherwise specified, the telescopic drive components are all driven by air pressure to avoid the generation of electric sparks as much as possible). When the fireworks tube 7 moves to the bottom of the bottom plate 6 and is sensed by the fireworks tube sensing probes 23, the limiting telescopic drive components 24 are controlled to move, and then the limiting plates 25 are used to block the front of the movement direction of the fireworks tube 7, thereby facilitating the sliding of the quantitative plate 5 for unloading in the next step.

[0038] In this embodiment, in order to enable the side of the firework tube 7 to abut against the limit plate 25, the limit plates 25 on both sides need to maintain a gap with the firework tube 7 when running to the limit position.

The belt medicine cleaning mechanism includes a medicine cleaning brush 30 and a medicine guiding groove 31. The medicine cleaning brush 30 is arranged in contact with the conveying belt 32 on the lower side of the belt conveyor 22, so as to brush off the medicine on the conveying belt 32. The medicine guiding groove 31 is installed below the medicine cleaning brush 30 for receiving and transferring the propellant brushed off.

[0041] In this embodiment, a driving motor 33 and a remote transmission shaft 34 are also included. In order to prevent electrical interference of the driving motor 33 and achieve the purpose of explosion-proof, the driving motor 33 is isolated and the remote transmission shaft 34 is connected to the driving roller 35 of the belt conveyor 22.
