[0041] Working principle:

[0042] When in use, the label to be cut is placed on the support base plate 1 and below the cutter, and between the first support plate 11 and the second support plate 12; the cutter is adjusted according to the size of the label and the width of the area to be cut, so that the distance between the two cutters is the same as the width to be cut;

[0043] The adjustment method is: start the driving motor 16 to drive the screw 14 to rotate in situ, so that the threaded sleeve 15 on the screw 14 moves left and right along the screw 14 in the transverse groove 13, driving the second support plate 12 to move left and right, and the movement of the second support plate 12 makes the slider 32 in the adjustment plate 3 fixed thereto slide along the slide groove 31, that is, the two sliders 32 move closer or farther away synchronously, and under the action of multiple scissor fork assemblies, the slider 32 in the adjustment plate 3 on the first support plate 11 slides along its slide groove 31 in the same way;

[0044] That is, multiple scissor assemblies are simultaneously expanded or contracted, so that the positions of the sleeves 42 are simultaneously changed, until the distance between two adjacent sleeves 42 is adjusted to be consistent with the required slitting width, and the movement of the sleeves 42 causes the adjustment block 23 and the telescopic cylinder 24 to follow the movement. After the adjustment is completed, the telescopic cylinder 24 is started to move its movable end downward, and the cutter is moved downward to cut the label;

[0045] In addition, a designated portion of the cutter can be moved downward by the telescopic cylinder 24 according to cutting needs.
