There are many label slitting devices in the prior art, for example, the Chinese utility model patent with the publication number CN213226380U discloses an electronic label slitting mechanism, which comprises a shell, a row of supporting rollers is arranged below the inside of the shell, a pay-off roller and a winding roller are arranged on the two sides of the supporting roller, a second lifting device is installed at the vertical corresponding position of the upper surface of the inside of the shell and the middle part of the supporting roller, a lifting table is welded to the lower power output end of the second lifting device, an installation groove is formed in the middle of the surface of the lifting table, and an electric drive slitting cutter is installed in the installation groove. The elastic pressure roller is arranged on the two sides of the slitting cutter, so that the pressure roller can press the electronic label in the cutting area of the slitting cutter. When the slitting cutter cuts, the electronic label does not shake, and the cutting is stable.

[0003] The cutting knives of the label slitting device used in actual production are mostly installed in the above-mentioned manner, that is, a plurality of cutting knives are arranged on the rotating shaft at intervals, which causes the following problems in actual production: the existing cutting methods are divided into two types, one is pressure cutting, and the other is shearing cutting. Since the thickness of the existing cutting knives is between 10 and 15 mm, the minimum size range of the cutting size is also fixed between 10 and 15 mm. In the process of multi-channel simultaneous production or small label production, there is a demand for small size cutting (≤10 mm). At present, the pressure cutting is limited by the size of the cutter holder, which limits the ability to cut small sizes. The shearing cutting is limited by the size of the upper knife seat and the lower knife seat, which limits the ability to cut small sizes, so that the above two cutting methods cannot be used when multi-channel production and production of some specific products require labels with a size of ≤10 mm. Therefore, a device is needed to realize smaller size cutting of the label roll. SUMMARY

[0004] The utility model aims at solving one of the above-mentioned technical problems, and provides a label misplacement slitting device which can realize smaller size cutting of the label roll.
