[0037] The present application is used for the stripping and cutting knife protection of the electronic detonator leg wire. The electronic detonator leg wire stripping machine targeted at is a stripping machine that adopts a method of cutting the outer skin with two blades opposite to each other. First, the movable knife holder 5 and the movable blade 9 are driven by the output of the driving cylinder 8 to push and cooperate with the fixed knife holder 4 and the fixed blade 10 to cut the outer skin of the electronic detonator leg wire. Then, the outer skin is separated by moving the peeling movable plate 3. When the electronic detonator leg wire is cut, the distance between the movable blade 9 and the fixed blade 10 can be limited by the abutment cooperation of the protection limit column 11 installed on the fixed protection positioning plate 6 and the movable protection positioning plate 7 and the adjustment limit assembly 12.

[0038] The adjustment limit assembly 12 includes a positioning bolt 121, on which an adjustment ring 122 is spirally sleeved. The axes of the adjustment ring 122, the positioning bolt 121 and the protective limit column 11 are on the same straight line, and the end surface of the adjustment ring 122 and the end surface of the protective limit column 11 are movably offset.

[0039] The adjustment limit assembly 12 is displaced by rotating the adjustment ring 122 on the external thread of the positioning bolt 121, thereby changing the position where the protective limit column 11 abuts the adjustment ring 122, thereby changing the spacing between the movable blade 9 and the fixed blade 10, which is suitable for stripping of electronic detonator pins of different diameters. At the same time, it can prevent the fixed blade 10 and the movable blade 9 from colliding when not working, thereby avoiding damage to the blades.

[0044] The end surface diameter of the protective limiting column 11 is larger than the outer diameter of the adjusting ring 122 .

[0045] The protective limiting column 11 can completely abut against the end surface of the adjusting ring 122 to increase the force-bearing area of ​​the abutment.

[0046] The telescopic members 124 are arranged in a ring array around the adjusting ring 122 .

[0047] The telescopic members 124 are arranged in a circular needle array to meet the requirements of more precise rotational positioning of the adjustment ring 122. For example, if two telescopic members 124 are provided, the adjustment ring 122 can be rotated at least half a circle, and four telescopic members 124 can achieve rotational positioning at least 1 / 4 circle.
