The coating can not only improve the aesthetics of the printed matter, but also improve the folding resistance of its surface, which is very beneficial to the smooth progress of the subsequent process. However, if the quality of the plastic film used for paper or lamination is poor, the indentation line may burst when the indentation is die-cut.
For example, when die-cutting the color box, bursting failure often occurs at the intersection of the indentation steel wire and the die-cutting knife. Burst only occurs in the film layer, and the indentation line along a certain direction is particularly serious, and the bottom paper generally does not burst. This shows that the failure has nothing to do with the operation of the machine and the pressure of the die-cutting machine, and the problem lies in the film material used for laminating. In response to this situation, the following measures can be taken to solve.
1. Replace the film raw materials.
2. If the product has not been processed yet, the paper feeding direction of the film can be changed.
3. Modify the die-cut version, divided into the following two situations.
(1) The processing of the whiteboard color box is shown in Figure 1. Use continuous knives at 1, 3, and 4 in the figure. Do not cut off and then connect the knives. The cutter heads at 2, 5 and 6 are extended by 2mm, and the angle is stamped to about 110 °.
(2) The treatment of corrugated cardboard packaging box is shown in Figure 2. Use continuous knives at 1, 2, 3, and 7 in the figure. Do not cut off and then connect the knives. 4. The cutting lines at 4, 5 and 6 are made into "U" shape with continuous knives.
By adopting the above method, the structure of the color box will not be changed, and the burst failure of the indentation line can be solved well.
The common quality problems of book glue binding are the necessary links in the book binding process. Good completion of this process will greatly improve the appearance of the book. If there are quality problems, it will undoubtedly reduce the grade of the entire batch of books. The quality of book binding is not enough to rely on the responsibility of the glue binding workers. It also involves technology, production process, raw material quality, workshop production environment, and even local climate conditions. Therefore, it is necessary to analyze common quality problems. And explore.
