A fully automatic explosion-proof heat shrinking machine

Abstract

The invention discloses a full-automatic anti-explosion heat shrinking machine. The full-automatic anti-explosion heat shrinking machine comprises a rack, an automatic film coating sealing and cuttingmachine, a full-automatic oil heating heat shrinking machine and a safety anti-explosion electric heating heat conduction oil furnace, wherein the automatic film coating sealing and cutting machine,the full-automatic oil heating heat shrinking machine and the safety anti-explosion electric heating heat conduction oil furnace are mounted on the rack. The automatic film coating sealing and cuttingmachine and the full-automatic anti-explosion heat shrinking machine are arranged in the same direction. The safety anti-explosion electric heating heat conduction oil furnace is arranged remotely. The oil furnace and the heat shrinking machine are connected through a pressure-resisting and high-temperature-resisting pipeline. The full-automatic anti-explosion heat shrinking machine comprises a rack, an inlet door assembly, an outlet door assembly, a heating box body assembly, a dragging chain assembly, an explosion venting hole assembly and a heating fan assembly, wherein the inlet door assembly, the outlet door assembly, the heating box body assembly, the dragging chain assembly, the explosion venting hole assembly and the heating fan assembly are mounted on the rack. The full-automaticanti-explosion heat shrinking machine is simple in structure, free of a strong magnetic field and high temperature, safe, reliable and high in production efficiency, full-automatic heat shrinkage canbe achieved, and the anti-explosion and explosion venting effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of special equipment for producing industrial detonators, in particular to a fully automatic explosion-proof heat shrinking machine. Background technique [0002] Under the action of electric energy, an electric detonator that detonates immediately is also called an instantaneous electric detonator. The time from power on to detonation is not more than 13ms, generally 4-7ms. The uniformity of its instantaneous detonation depends on the total resistance of the electric detonator and the resistance of the bridge wire. Therefore, the full resistance should be tested before the product leaves the factory and before use. The smaller the error of the full resistance, the better the uniformity of detonation. It is suitable for detonating explosives, detonating cords, detonating tubes, etc. in blasting projects such as open-pit and underground mining, road construction, and water conservancy construction.

AI Technical Summary

Problems solved by technology

At present, the two moisture-proof methods are manually operated, resulting in too many people on site, poor safety, low efficiency and irregular packaging surface, and subsequent measures such as automatic packing cannot be realized.

[0005] At present, the heating process of the heat shrinkable film wrapping process is mostly heated by a heating tube, and the temperature of the heating surface is too high, far exceeding the surface temperature requirements of the electrical equipment of the electric detonator production line.

And the heat shrink packaging machine currently used has no anti-explosion and anti-explosion measures, so it cannot be used on the electric detonator production line
