Technical Field
[0001] The utility model relates to the technical field of engineering blasting, in particular to a multifunctional charging tool. Background Art
[0002] Due to the promotion of new technologies, the outer packaging tape of emulsion explosive rolls began to adopt plastic film packaging technology. This composite film packaging method is similar to the packaging method of ham sausage. Compared with the original paper tube packaging method, it is stronger and not easy to break. However, before placing the composite film emulsion explosives at the detonation site, it is necessary to control the charging amount according to the blasting process and method. This involves cutting the composite film emulsion explosives, cutting the explosive packaging tape into a certain length, and then punching holes on the end face of the explosive packaging tape to facilitate the installation of the detonator. In the blasting operation, small auxiliary tools will be involved, such as knives. It is not allowed to use ferrous metals such as steel.
