Description

Knife roller for producing flexible anti-folding labels Technical Field The utility model belongs to the technical field of die cutting tools, and particularly relates to a cutter roller for producing a flexible anti-folding label. Background The flexible anti-metal label is called as a flexible anti-metal label, and can be read and written normally in a metal surface environment. There are two general types of existing flexible labels, one is an unfolded flexible label and the other is a folded flexible label, wherein the folded flexible label refers to that one end of the flexible label is folded. Because of the self structure of the flexible anti-folding label, adhesive materials with larger viscosity are needed to be used between materials of each layer such as a surface material, a general knife roll is adhered with the adhesive materials on a knife edge when die cutting is carried out, the adhesive materials are transferred to the surface of a product again, residual adhesive is remained, and the appearance and printing of the product can be influenced. In addition, after the die cutting of the existing knife roller is finished, the product can be clamped into the knife roller, and smooth separation is difficult. Disclosure of utility model The utility model provides a cutter roller for producing a flexible anti-folding label, which is used for solving the technical problems that adhesive materials are adhered in the die cutting process of the conventional cutter roller, residual adhesive is left on the surface of a product, the appearance quality and the printing effect are affected, the product is clamped into the cutter roller, and the die cutting is not smooth. In the utility model, a plurality of blades are annularly and uniformly distributed on the peripheral surface of the knife roller; The adjacent blades are connected through short blades; Anti-sticking coatings are plated on the cutting edge and the short edge; The cutting edge is annular or U-shaped, and the width of the cutting edge is matched with the width of the flexible anti-folding label; The length of the cutting edge is matched with the unfolding length of the flexible anti-folding label, specifically, the length of the cutting edge is at least 1mm larger than the unfolding length of the flexible anti-folding label, and the general range is 1-5 mm. The utility model prevents the sizing material from adhering to the blade through the anti-sticking coating, thereby preventing the sizing material from being transferred to the surface of the product. The anti-sticking coating is a diamond-like carbon coating, has the advantages of high hardness of diamond and lubricity of graphite, is an amorphous coating film formed by carbon and hydrogen, and has good anti-sticking property. The die-cutting process has the beneficial effects that as the cutting edge is protruded outside the cutter roller, in the die-cutting process, a die-cut product can be clamped in a groove formed by the cutting edge, and once the die-cut product cannot be removed from the groove of the cutting edge in time, the next die-cutting effect is affected. The method has the advantages that the height of the cutting edge is 1.7+/-0.1 mm, the width of the cutting edge tip of the cutting edge is 0.01-0.03 mm, and the method has the advantages that the cutting edge can be used for die-cutting flexible anti-folding labels and does not hurt base paper, and production continuity is maintained. The thickness of the foam cushion layer is 1.5+/-0.1 mm, and the beneficial effect of the step is that the height difference exists between the foam cushion layer and the cutting edge, so that the die cutting effect is not affected. The beneficial effects of the utility model are as follows: 1. According to the utility model, the anti-sticking coating is arranged on the cutting edge of the cutter roller, so that the cutting edge is prevented from bringing out the sizing material on the flexible anti-folding label, and the appearance of the flexible anti-folding label is protected; 2. In addition, a foam cushion layer is arranged in the central area of the cutting edge, so that the flexible anti-folding label is prevented from being clamped in the cutting edge, and smooth die cutting of the flexible anti-folding label is ensured.
