[0003] In view of the characteristics of the double-sided adhesive material, the die-cutting dies on the market have the following disadvantages: when using these ordinary die-cutting dies to die-cut the double-sided adhesive material, part of the glue on the edge of the double-sided adhesive material will be taken out by the blade of the die. cause glue overflow
Some cutting dies are treated with AF coating, but the coating of these cutting dies is not wear-resistant during the cutting process, the life of the cutting dies is short, and it cannot play the role of anti-overflow glue
There are also some dies whose blades are coated with Teflon to reduce glue overflow, but this kind of dies may not move when cutting thick double-sided adhesive materials (for example, the thickness of the glue is greater than 0.10mm). , in addition, the cutting edge of the knife die coated with Teflon will still not be wear-resistant

Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] figure 1 It is a schematic diagram of the die cutter 100 in the present invention. like figure 1 As shown, the knife die 100 of the present invention includes a knife holder 200 and a cutter 300 connected to the knife holder 200 . Wherein the knife rest 200 is made of metal or plastic, has a mounting groove on the knife rest 200, and the cutter 300 is embedded in the mounting groove, thereby being fixed on the knife rest 200. The knife 300 includes a cutting edge 301 and a coating layer 302 attached to the cutting edge 301 . Wherein the blade 301 is made of metal such as stainless steel....

Abstract
The invention relates to a cutter and a film coating technology thereof. The cutter comprises a blade, and a film coating layer which is attached to the blade, wherein the film coating layer comprises a grafting film layer which is a niobium or stainless steel film layer, an indium-tin alloy film layer, a hardness reinforcing layer which is a titanium nitride or silicon nitride film layer, and a releasing type force reinforcing layer which is a monocrystalline silicon or calcium fluoride or magnesium fluoride film layer; the grafting film layer, the indium-tin alloy film layer, the hardness reinforcing layer and the release type force reinforcing layer are sequentially arranged from inside to outside on the film coating layer. The cutter can be prevented from glue overflowing and is high in abrasion resistance.
Description
technical field [0001] The invention relates to the field of cutting tools, more specifically, to a cutting tool and its coating process. Background technique [0002] In the special printing industry, for the convenience of products with double-sided adhesive (such as die-cut parts, decorative and functional LOGO, battery labels, cleaning products and cosmetic labels, electronic product appearance feature labels, etc.) and precision mechanical parts or The product fits better and faster, and the double-sided adhesive material is often die-cut by a knife die to make the final double-sided adhesive product. [0003] In view of the characteristics of the double-sided adhesive material, the die-cutting dies on the market have the following disadvantages: when using these ordinary die-cutting dies to die-cut the double-sided adhesive material, part of the glue on the edge of the double-sided adhesive material will be taken out by the blade of the die. Cause overflow glue phenom...
