How to solve the problem that the cutting edge of corrugated carton cannot be closed after die cutting

ask: after die cutting, the knife edge of the corrugated box can't be closed, which is very rough. Compared with the sample box of the customer, the step-by-step comparison method is adopted, and the thickened elastic pad can't achieve that effect. How to solve it? A: 1. Your tile paper is sure to be the same as the guest sample version. The guest's version has a crimp when the beer box is in this version, so its pit doesn't look obvious. When you open the knife mold, you can tell the knife mold factory that they will know. 2. These have something to do with the material, the knife mold, the direction and the master who starts the machine. It depends on what is wrong. 3. If you don't put it too long after pasting, it's easier to achieve the effect if the moisture is a little larger. Such as% moisture. 4. Is the pit height the same? For example, the customer used pit F as it is. Did you use pit e? Is the weight of the bottom paper core and the top paper the same? From the picture, it has a lot to do with the material. The customer combined with the overall deployment of scientific and technological system reform, the material should be thin, and the bottom paper is obvious. If it is a color box, it is recommended not to let go too long after mounting the pit, and then die-cutting as soon as possible. 18mm thick plate shall be used for the knife template, and the rubber pad shall be continuous. 5. It should be easy to solve this problem, that is, install a harder spring pad on both sides of the knife line. 6. It's the side knife part. One side of the die-cutting knife is glued with arch glue and then installed into the tensile testing machine. Speaking of plastic strips, right? The arch glue strips are hard and elastic, so that the edge of the pit paper can be pressed flat without indentation
