DETAILED DESCRIPTION

[0015] like Figure 1 to Figure 2As shown, an emulsion explosive cutting device comprises a base 1, a fixed block 2, a slide rail 3, a sliding block 4, a knife holder 5, a cutter 6, a screw 7 and a spring 8, wherein the fixed block 2 is mounted on the base 1, and a V-shaped groove and a baffle 21 are provided on the fixed block 2 for placing the emulsion explosive roll, the slide rail 3 is two parallel cylindrical rails, one end of the slide rail 3 is mounted on the fixed block 2, and the other end of the slide rail 3 is fixedly mounted on the base 1 to ensure that the slide rail 3 is mounted horizontally, and the sliding block 4 is slidably mounted on the slide rail 3, the sliding block 4 is provided with a through V-shaped groove along the direction of the slide rail 3, and is used to place the medicine roll in cooperation with the fixed block 2. A knife holder 5 is installed on the sliding block 4 by screws 7, which is convenient for maintenance of the cutter 6. A slide groove 52 is provided on the inner side of the knife holder 5, and a through hole is provided on the top of the knife holder 5. The cutter 6 includes a cutter head 61, a sliding part 62, a knife handle 63 and a pressing part 64. The knife handle 63 passes through the through hole, and the sliding part 62 slides with the slide groove 52 to cut The knife 6 is mounted on the knife holder 5, and the pressing portion 64 and the knife handle 63 are detachably mounted. A spring 8 is provided between the knife holder 5 and the pressing portion 64, and the spring 8 is mounted on the knife handle 63. The cutter 6 is kept in the upper position of the knife holder 5 by the action of the spring 8 in a natural state. When the pressing portion 64 is subjected to downward pressure, the spring 8 is compressed, and the cutter 6 moves downward along the slide groove 52 to cut the medicine roll.
