Method for reducing breakage rate of emulsion explosive paper tube breakage rate

The invention relates to a method for reducing breakage rate of an emulsion explosive paper tube, which is characterized in that a small belt conveyor is mounted between a tube rolling machine and a large belt conveyor; the belt conveying direction of the small belt conveyor is the same as the tube unrolling direction of the tube rolling machine and is perpendicular to the belt conveying direction of the large belt conveyor; the belt mounting height of the small conveyor is level with the tube unrolling height of the tube rolling machine; the paper tubes rolled by the tube rolling machine are conveyed to the opposite large belt conveyor through the small belt conveyor; a cooling chamber is arranged on the conveying path of the large belt conveyor; the large belt conveyor penetrates through the cooling chamber; the temperature of the cooling chamber is set below 18 DEG C. The method disclosed by the invention has the following advantages: the method is simple, the equipment is reliable in operation, the mainte
