Automatic packaging machine for emulsion explosive cartridge

Abstract

The invention discloses an automatic packaging machine for an emulsion explosive cartridge. The automatic packaging machine comprises a frame, a quantitative filling device, a membrane releasing device, a lamellar membrane cylinder former, a vertical welding device and a horizontal welding device, wherein the quantitative filling device, the membrane releasing device, the lamellar membrane cylinder former, the vertical welding device and the horizontal welding device are arranged on the frame respectively; the membrane releasing device comprises a membrane placing rack and a membrane releasing mechanism; the membrane placing rack is arranged above the frame; the membrane releasing mechanism is arranged inside the frame; the lamellar membrane cylinder former is sleeved on a discharge pipe;the vertical welding device is arranged inside the frame and comprises a vertical welding knife which is parallel to the discharge pipe; and the horizontal welding device is arranged inside the frameand comprises two horizontal welding knives which are symmetrically arranged below an outlet of the discharge pipe. The automatic packaging machine for the emulsion explosive cartridge has the advantages of safe and reliable filling manner, no influence to the using property of an explosive, compact structure, convenient multistation arrangement and large capacity.

Description

Technical field [0001] The invention relates to an explosive charging machine, in particular to an automatic packaging machine for emulsion explosives rolls. Background technique [0002] In the Chinese patent literature, there is a patent report of an invention patent that discloses an automatic packaging machine for emulsion explosives. It includes a vacuum quantitative filling machine, a heat sealing machine and a double card sealing machine. The vacuum quantitative filling machine uses a vane pump. The vane pump has an impeller; the impeller is provided with an inner stator cam, the impeller has an outer stator cam, and the cam surface is provided with protrusions and depressions to make the blades extend / retract into the outer periphery of the impeller . The vacuum quantitative filling machine is provided with a filling tube, the heat sealing machine is provided with a heat sealing tube, and the filling tube is inserted and arranged in the heat sealing tube. The filling me...

AI Technical Summary

Problems solved by technology

The filling method of the above scheme is to use a pressure pump with a metal rotor (such as a vane pump, a gear pump, etc.) to fill. Such a mechanism poses a great safety hazard to the production of explosives; the ends of the drug rolls are punched with aluminum wires. Sealed, due to the need to squeeze the explosive when punching the card, the physical structure of the explosive is seriously damaged, thereby affecting its performance; and its equipment is huge and complex, and it is difficult to achieve multi-station layout, so its production capacity is low

[0003] In addition, if the method of heat sealing at the end is used, the mechanism can be simplified too much, but the emulsion explosive is a paste-like solid substance with high viscosity, and there are two major problems that need to be solved in the method of heat sealing at the end of the roll.

First, it is difficult to separate the materials on the plastic film

Second, according to the use requirements of explosives, the width at the end cannot be greater than the diameter of the coil

Therefore, the existing explosive roll production machinery has not yet adopted end heat sealing.
