In this regard, the present invention provides a cutting device 10. Fig. 1 is a schematic structural diagram of a cutting device 10 according to a first embodiment of the present invention; FIG. 2 is an exploded view of the cutting device 10 shown in FIG. 1;

fig. 3 is a schematic view of the first tool 110 and the second tool 120 shown in fig. 1. As shown in fig. 1 to 3, the cutting device 10 provided by the present invention comprises a first cutter 110, a second cutter 120 and a driving member 130; the first cutter 110 is coupled to the second cutter 120 in a vertical direction; the first cutter 110 and the second cutter 120 both have inclined planes, the inclined planes form a blade, and the width of the blade of the first cutter 110 is greater than that of the blade of the second cutter 120; the first cutter 110 is connected with a power output end of the driving member 130, the driving member 130 is used for driving the first cutter 110 to reciprocate relative to the second cutter 120 along the vertical direction, and the first cutter 110 and the second cutter 120 are matched to compress the material 1000 so as to cut the material 1000.

In this embodiment, the first cutter 110 is coupled to the second cutter 120, which means that the two can be close to each other to cut the material 1000. The material 1000 is placed between the cutting edge of the first cutter 110 and the cutting edge of the second cutter 120, and the first cutter 110 is driven by the driving member 130 to move relative to the second cutter 120, so that the first cutter 110 is in contact with the second cutter 120. The edges of the first and second cutters 110, 120 are sharp enough that the material 1000 can be sheared by the cooperation of the first and second cutters 110, 120. The magnitude of the cutting force is controlled by the magnitude of the acting force applied by the driving member 130, so that the cutting force acting on the material 1000 is consistent, and the cut of the material 1000 is smooth. When cutting, the upper surface of the material 1000 is in contact with the first cutter 110, the lower surface is in contact with the second cutter 120, and the second cutter 120 is fixed relative to the material 1000, so that the cut of the material 1000 is positioned in the cutting edge of the second cutter 120, and by designing that the width of the cutting edge of the first cutter 110 is larger than that of the cutting edge of the second cutter 120, the material 1000 in contact with the second cutter 120 can be completely disconnected from the cut, and the phenomena that the cutting quality is affected by adhesion of hair lines and the like can not be generated, so that the cutting quality of the material 1000 is ensured, and the use experience of a user is improved; and, the length of two cutters is unanimous, because its cutting edge width is different for the cutting edge area of two cutters is different, therefore the pressure of the cutting edge department of two cutters is different, thereby when cutting, can avoid the tool setting phenomenon of first cutter 110 and second cutter 120, prevent that the cutting edge from collapsing and falling the subsequent cutting of influence, and then influence the cutting efficiency of material 1000, prolonged the life of first cutter 110 and second cutter 120, and then reduced the maintenance cost and the replacement cost of cutter. Specifically, the material 1000 may be paper, the driving member 130 may be an air cylinder, and a piston rod of the air cylinder is connected to the first cutter 110.

In one particular embodiment, the difference between the edge width of the first cutter 110 and the edge width of the second cutter 120, i.e., the difference in bevel length, D, is 0.1cm to 0.5cm, as shown in fig. 3. The difference value of the width of the cutting edge is set within a reasonable range, so that the cutter is prevented from being damaged while the cutting effect is guaranteed. Since the first knife 110 directly acts on the paper and the second knife 120, if the difference between the widths of the two knife edges is too large, the difference between the pressures of the first knife 110 and the second knife 120 at the knife edges is too large, so that the first knife 110 may be crushed or the first knife 110 may be crushed after the knife is dropped. If the edge width of the first cutter 110 is smaller than the edge width of the second cutter 120, the first cutter 110 is a force applying body, and thus, incomplete cutting of the paper placed on the second cutter 120 may occur. Further, the first cutter 110 and the second cutter 120 are both flat plate structures, so that the stress balance of the whole cutter is ensured, and the whole cutting device 10 is compact in structure and reasonable in space utilization due to the fact that the first cutter 110 and the second cutter 120 are both regular-shaped structures.
