[0014] As shown in Figure 1 , Figure 3 , the embodiment provides a label cutting device, which comprises seven cutting pieces 1, a motor 2 and an arc-shaped plate 3.

[0015] Specifically, the arc-shaped plate 3 is provided with an end plate 31 at each end, the end plate 31 is rotatably arranged on a corresponding support plate 4, the motor 2 is arranged outside one of the support plates 4, the output shaft of the motor 2 is used to drive one of the end plates 31, thereby driving the arc-shaped plate 3, the side wall of the arc-shaped plate 3 is provided with seven guide grooves 32, the number of the guide grooves 32 is consistent with the number of the cutting pieces 1, the distance between the two adjacent guide grooves 32 is equal, as shown in Figure 4 , the distance between the two ends of the adjacent guide grooves 32 is different, and the distance gradually increases from top to bottom.

[0016] Specifically, as shown in Figures 1-3 , each cutting piece 1 comprises a blade 11, an inverted U-shaped plate 12 and a guide column 13, the guide column 13 is arranged at the top of the inverted U-shaped plate 12, the guide column 13 is matched in the corresponding guide groove 32, the blade 11 is arranged in the inverted U-shaped plate 12, and a horizontal plate 41 is arranged between the two support plates 4, the horizontal plate 41 is not a cylinder, in the embodiment, the horizontal plate 41 is a cuboid, and the blade 11 and the inverted U-shaped plate 12 are horizontally and slidingly matched with the horizontal plate 41.

[0017] In use, the raw paper with labels pasted thereon is conveyed from below the blade 11, the blade 11 cuts the raw paper to obtain a plurality of label strips; for labels of different sizes, the position of the blade 11 needs to be adjusted, which is very simple, and the principle is as follows: the motor 2 is started to make the arc-shaped plate 3 rotate, thereby making the guide column 13 move along the respective guide grooves 32, since the blade 11 and the inverted U-shaped plate 12 are limited by the horizontal plate 41, when the guide column 13 moves along the respective guide grooves 32, the blade 11 and the inverted U-shaped plate 12 will only move horizontally along the horizontal plate 41, thereby expanding or reducing the distance between the two adjacent blades 11. Through the above scheme, the positions of all the blades 11 can be automatically adjusted, and the blades 11 can be quickly and accurately moved to a specific position, greatly improving the efficiency.

[0018] In order to further improve the stability of the cutting piece 1, a protruding block 14 is arranged between the inverted U-shaped plate 12 and the guide column 13, the diameter of the protruding block 14 is greater than that of the guide column 13, and the top surface of the protruding block 14 is tangent to the arc-shaped plate 3.

[0019] In the preparation work before slitting, the raw paper needs to be passed under the blade 11. During this process, since there are no protective measures around the blade 11, there are many safety risks. To solve this problem, this embodiment adopts the following measures: Figure 5 As shown, the device also includes two protective rollers 5 and two lifting rods 6. The two protective rollers 5 are located on both sides of the horizontal plate 41, and all the blades 11 are located between the two protective rollers 5. The lowest surface of the protective rollers 5 is higher than the lowest surface of the blades 11. The top of the lifting rod 6 is provided with a U-shaped base 61, and the support plate 4 is provided with a through groove 42. The shape of the top of the through groove 4 is consistent with the shape of the U-shaped base 61. The lifting rod 6 and the U-shaped base 61 are located in the through groove 42. The ends of the protective rollers 5 are rotatably connected to the corresponding U-shaped bases 61. The power source of the lifting rod 6 is driven by a cylinder or a hydraulic cylinder to control the height of the U-shaped base 61 and the protective rollers 5.

[0020] The method of use is as follows: Use two lifting rods 6 to lower the two U-shaped bases 61, causing the two protective rollers 5 to move down until the lowest surface of the protective rollers 5 is lower than the lowest surface of the blade 11, so that the raw material paper can pass under the blade 11 before slitting. Under the action of other winding rollers, the raw material paper is kept tightly against the two protective rollers 5, and the protective rollers 5 play a protective role, improving safety. Then use the lifting rods 6 to reset the U-shaped bases 61 and protective rollers 5 upward. During the upward movement of the protective rollers 5, under the action of other winding rollers, the raw material paper is kept tightly against the two protective rollers 5 until the blade 11 contacts the raw material paper.

[0021] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
