For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element without departing from the teachings of the present application.

[0032] In combination Figures 1 to 3 As shown in the drawings, the slitting device of the multi-layered adhesive label of the present embodiment comprises a slitting conveying roller 1 and a slitting assembly 2.

[0033] Specifically, the slitting conveying roller 1 comprises an upper roller body 10 and a lower roller body 11 aligned vertically, and the multi-layered adhesive label B passes through the upper roller body 10 and the lower roller body 11 and forms a common cutting section b1 which is common to the upper roller body 10 and the lower roller body 11, wherein the upper layer label and the lower layer label move horizontally, and the common cutting section b1 is transmitted from top to bottom.

[0034] The slitting assembly 2 is outside the common cutting section b1 and comprises a fixed rod 20 arranged in parallel with the slitting conveying roller 1 and a slitting cutter 21 mounted on the fixed rod 20.

[0035] In some embodiments, the fixed rod 20 is located outside the common cutting section b1, the slitting cutter 21 comprises a cutter disc seat 210 movably and adjustably mounted on the fixed rod 20, and a blade body 211 linearly moves and adjusts along the radial or chord direction of the cutter disc seat 210, wherein the blade body 211 has a blade part facing upward and opposite to the moving direction of the label of the common cutting section b1, the cutter disc seat 210 adjusts the included angle between the blade part and the common cutting section according to the thickness change of the multi-layered adhesive label B, and the included angle is less than or equal to 45°. The thickness of the multi-layered adhesive label B is inversely proportional to the included angle. That is, the thicker the thickness is, the more difficult it is to cut, so the angle of cutting is important. Generally, the included angle between the blade part and the common cutting section is 10-30°. Based on the change of the angle, the vertical component force formed matches the resistance formed by the label, so that the cutting is implemented in a stable force. In this example, the moving direction of the label of the common cutting section b1 is from top to bottom, and the blade part is arranged upward. This is an embodiment, and of course the two directions can be interchanged.

[0036] In this example, the cutter disc seat 210 is adjustably arranged by sliding along the length direction of the fixed rod 20 and rotating around the fixed rod 20. That is, the angle is adjusted in rotation and the slitting position is adjusted in sliding, so as to meet the slitting needs in different use conditions and increase the practicability of slitting.

[0037] The cutter seat 210 comprises a disc body a for the fixed rod 20 to cross, a die seat body b installed on the disc body a and forming a cutter slot with the disc body a, wherein the cutter body 211 is installed on the cutter slot, and the disc body a is rotatably and slidably installed on the fixed rod 20. The disc body a is provided with locking bolts 22, and the positioning is formed based on the interference of the locking bolts 22 and the fixed rod 20. The cutter slots are distributed on the die seat body b, and the end surface of the disc body a is a plane. The assembly between the two is facilitated without the need for alignment. Meanwhile, in this example, the length of the cutter body 211 protruding out of the cutter slot is relatively short, generally one or two sections.

[0038] In addition, the outer side of the die seat body b is flush with the circumferential contour of the disc body a, and the inner side of the die seat body b interferes with the outer side of the fixed rod 20. In this way, not only is the assembly alignment convenient, but the interference of the inner side further increases the firmness of the positioning. In the axial orthographic projection of the fixed rod 20, the outer side of the die seat body coincides with the circumference of the disc body, and the inner side of the die seat body extends along the chord direction of the disc body and is tangent to the fixed rod. The tangent positioning not only allows the position to be adjusted in rotation, but also can maintain the interference at any angle.

[0039] In summary, after adopting the slitting device, the transmission direction formed based on the tangent segment and the blade part of the cutter are opposite, and the cutting is performed in the changeable included angle formed to slit the multi-layer labels at the specified positions, therefore, on the one hand, the cutter adopted by the utility model is adaptively matched with the label thickness according to the angle to implement the slitting of various labels, and the cutter adopted is a conventional cutter body, that is, the cost of slitting is low; on the other hand, based on the decomposition of the force formed in the slitting, the slitting resistance is maximized, and the inward force acting on the label is small, so that the label is not displaced to enable the cutting to be performed at the relatively constant position and angle, improve the flatness of the cut and the quality of the slitting; on the third aspect, the included angle between the blade part and the tangent segment is 10-30°, based on the change of the angle, the vertical component force formed matches the resistance formed by the label to enable the cutting to be performed in the stable force, meanwhile, the thickness of the multi-layer adhesive label is inversely proportional to the included angle, that is, the thicker the thickness, the more difficult the cutting, so the cutting angle is very important; on the fourth aspect, the label moving direction of the tangent segment is from top to bottom, and the blade part is arranged upward, which is an implementation manner, of course, the two directions can be interchanged; on the fifth aspect, the angle is adjusted in rotation, and the slitting position is adjusted in sliding to meet the slitting needs under different use conditions and increase the slitting practicability; meanwhile, the positioning is formed based on the interference of the locking bolts and the fixed rod; on the sixth aspect, the cutter slots are distributed on the die seat body, and the end surface of the disc body is a plane. The assembly between the two is facilitated without the need for alignment, meanwhile, the outer side of the die seat body is flush with the circumferential contour of the disc body, and the inner side of the die seat body interferes with the outer side of the fixed rod. In this way, not only is the assembly alignment convenient, but the interference of the inner side further increases the firmness of the positioning; in addition, the tangent positioning not only allows the position to be adjusted in rotation, but also can maintain the interference at any angle.
