When the bag is filled by the filling and molding mechanism 5, the bag conveying mechanism 13 continues to convey backward, and the top of the bag passes through the seal above the rear end of the bag conveying mechanism 13 and is gradually sealed. The upper and lower ends of the bag are separately sealed by the sealing assembly 26, so that the filling of the emulsion explosive is completed.

A plurality of temporary storage tubes 6 are arranged vertically side by side. A top slide 7 is fixed on the top of each temporary storage tube 6 by welding. The top slide 7 is flush with the top of the temporary storage tube 6. A through hole with the same radius as the temporary storage tube 6 is opened on the top slide 7. The top of the top slide 7 fits with the bottom of the sealing slider 2.

The edges of the top slides 7 of the multiple temporary storage tubes 6 fit together. When the temporary storage tube 6 moves, if there is a gap in the top slide 7, the emulsion explosive in the extrusion tube will leak.

The temporary storage cylinder 6 is filled by the extrusion tube 1.A lifting rod 11 passing through the guide track 4 is installed on another straight section of the annular guide track 4. A groove for the piston 10 to pass through is opened at the bottom of the guide track 4, that is, when the temporary storage tube 6 moves, the piston 10 needs to give way to the temporary storage tube 6, so that the piston 10 is retracted into the groove at the bottom of the guide track 4. The lifting rod 11 is connected to the top of the piston 10 by bolts. The lifting rod 11 passes through the guide track 4 and extends into the groove body at the bottom of the guide track 4.

The tops of multiple lifting rods 11 are fixed on the same flat plate by welding, and the pressing cylinder 12 is fixed on the flat plate by bolt fastening. The piston 10 of the pressing cylinder 12 is fixed on the top surface of the annular guide track 4 by bolt fastening. The flat plate is lowered by retracting the pressing cylinder 12, so that the lifting rod 11 is lowered and extends into the temporary storage tube 6, and the piston 10 in the temporary storage tube 6 presses down for filling. ;

Clamping plates 33 are arranged on the left and right sides of the bag, and columns are installed on the ground by bolt fastening. The conveying gear is installed on the column by bearings, and is fixed to the column by bolt fastening. When the clamping arm 32 moves to the position of the two clamping plates 33 through the vertical conveying chain 30, the clamping arm 32 closes to clamp the side of the bag body, and then the bag body is conveyed downward to the bag body conveying mechanism 13 through the conveying chain 30, and the clamping arm 32 is pressed together by the clamping plate 33, and the tops of the two clamping plates 33 are bell mouths;When starting work, the end of the bag body is pulled down between the clamping arms 32, and the conveying chain 30 moves downward, and the bag body is pulled down at the same time.
