FIELD: demolition works.SUBSTANCE: invention relates to cartridging of explosives for mining industry. The method of cartridging of blasting powders comprises the formation of vertically aligned cartridge shell from thermoplastic film on the forming pipe, cartridging using a rotating injecting worm located inside the forming pipe, by periodic filling of continuously dragged explosive shell and plugging of cartridge ends by sealing clips, crimping of the shell into a bundle, attaching of clips and cutting of the bundle at disabled injecting worm. Depending on the required density of explosive in the cartridge the speed and momentum of variable worm drive are set. The cartridging device contains a feeder, injecting worm, located inside the forming pipe and fitted with the rpm sensor and variable drive, sleeve former, device for longitudinal welding or gluing of the shell, shell dragging mechanism, device for feeding the thermoplastic film tape with a vertical drive, tape motion monitoring sensor, manufacturing mechanisms, clip attaching and ready cartridge cutting units, monitoring and control unit of injecting worm drive, unit of monitoring of rpm and movement of cartridge shell.EFFECT: invention allows to implement high capacity, efficient and safe technology of manufacturing of high quality cartridges from blasting powders.4 cl, 3 dwg |
