[0133] Production process:

[0134] Digital dispensing: Multiple explosive feeders quantitatively deliver different explosive raw materials to the dispensing conveyor belt. Then, the dispensing pouring trough receives the explosive raw materials on the dispensing conveyor belt and transfers them to the explosive transfer robotic arm. The explosive transfer robotic arm then transfers the explosive raw materials to the automated mixing and explosion-proof room for mixing. During this process, the explosive raw material information display screen can display the name, weight, and other information of the explosive raw materials in real time, realizing digital dispensing.

[0135] Automated mixing: The explosive transfer robotic arm moves and puts the explosive raw materials on its scoop into the upper pipe opening of the inclined explosive transfer pipe. At this time, the explosive raw materials automatically slide out of the lower pipe opening of the explosive transfer pipe by weight and enter the explosive mixing and screening device for thorough mixing. After that, the mixed explosives are conveyed by the explosive conveyor belt and received by the scoop on the explosive transfer robot, and the explosives are transferred to the explosive filling explosion-proof room for filling operations.

[0136] Standardized filling and palletizing: During filling, the barrel shell conveyor line transports the barrel shells to the area below the explosive filling machine. The explosive filling machine fills the barrel shells with explosives. The barrel shells filled with explosives are then transported by the barrel shell conveyor line to the area below the sawdust filling machine to fill with sawdust. The barrel shells filled with sawdust are then transported by the barrel shell conveyor line to the area below the sawdust compactor to compact the sawdust. The barrel shells are then transported by the barrel shell conveyor line to the area below the clay filling machine to fill with clay. The barrel shells filled with clay are then transported by the barrel shell conveyor line to the clay compactor to compact the clay. After that, the filled barrel shells are transported by the barrel shell conveyor line to the position of the palletizing robot for automatic palletizing.

[0137] Cleaning and Drying: Afterwards, the cleaning nozzles automatically rinse the equipment in the explosion-proof mixing and filling rooms, ensuring no drug residue remains and facilitating accurate drug preparation and filling for the next use. Following cleaning, a self-propelled air dryer automatically moves to quickly dry the explosion-proof mixing and filling rooms, preparing them for the next filling cycle.

[0138] This production line achieves digital dispensing, automated mixing, and standardized filling of explosives through a digital dispensing room, an automated explosion-proof mixing room, an explosion-proof explosive filling room, and a sawdust and clay filling room.
