During the manual filling process, because the force of different people is different, the volume occupied by the initiating explosive is inconsistent. The inconsistent volume of the same amount of initiating explosive filling leads to different densities of the initiating explosive filling, which leads to inconsistent combustion speed, and further leads to inconsistent force during the initiation. Therefore, the setting of the sealing paper and the positioning cylinder can limit the movement position of the sealing paper during the filling process of the sealing paper, thereby restraining the sealing paper so that the sealing paper does not extrude the initiating explosive, and further ensuring the consistent volume of the same amount of initiating explosive filling, thereby ensuring the consistent force during the initiation.
