一般我们把瓦楞纸板折痕线部位在加工、折叠、装箱及堆垛时出现的面里纸爆裂的现象称为爆线。瓦楞纸板爆线会影响纸箱的空箱抗压值，相同也会影响纸箱的外观，是困扰纸板出产的严峻质量缺陷之一。材料、环境、设备、操作方法等都会形成纸板爆线大多数纸板质量问题的产生原因一般都是多方面的，爆线也是如此。其本源触及材料、环境、设备、操作方法等各大要素。纸箱爆线类型分为几种，一种是里纸爆线，还有一种就面纸爆线
Generally, we call the bursting of paper in the surface of corrugated board crease line during processing, folding, packing and stacking as burst line. The bursting line of corrugated board will not only affect the empty box compression value of the carton, but also affect the appearance of the carton. It is one of the severe quality defects perplexing the production of paperboard. Materials, environment, equipment, operation methods, etc. will form the paperboard burst line. The causes of most paperboard quality problems are generally multifaceted, and so is the burst line. Its origin involves materials, environment, equipment, operation methods and other major elements. There are several types of carton bursting, one is inner paper bursting, and the other is face paper bursting
其间纸箱面纸爆线主要原因：1压线压力调整不妥2、纸板水分太低处理纸箱面纸爆线要从以下方面多做改进：印刷压线必求深：印刷机在出产过程中由于压线压力过重易导致印刷爆线。如果将预压轮压重，纸箱不爆线，可是纸箱成型就欠好，纸箱四边出现圆角现象。纸箱压线太浅纸箱成型就会形成剪刀差，接缝巨细等现象，所以压线就必求深。
In the meantime, the main reasons for the bursting line of carton paper are as follows: 1. The pressing pressure is not adjusted properly. 2. The moisture content of paperboard is too low. The bursting line of carton paper should be improved from the following aspects: the printing pressing line must be deep: the printing machine is easy to burst due to the excessive pressing pressure in the production process. If the preloading wheel is pressed, the carton will not burst, but the carton forming is not good, and the rounded corners appear on the four sides of the carton. If the carton pressing line is too shallow, the carton forming will form the phenomenon of scissors difference and the size of joints, so the pressing line must be deep.
预压轮压力：操控在纸板厚度的一半左右为佳印刷机的压线部分为预压轮（压溃轮）和压线轮组成。如果压溃轮的压力调整过轻，那么预压的压力就不足，纸板压线处的硬度就会添加，这样成型时易出现内强外弱的现象，也就是由于瓦楞纸板里纸加瓦纸向外揉捏的强度就会变大，形成面纸在拉伸过程中纸的纤维出现开裂，然后导致面纸破损。相同压线痕迹不明显，成型作用就更差，如单单把压线压力加大，压线痕迹是清晰的，可是里纸爆裂的程度就会加大。
Preloading wheel pressure: it is better to control it at about half the thickness of the paperboard. The crimping part of the printing press is composed of preloading wheel (crushing wheel) and crimping wheel. If the pressure adjustment of the crushing wheel is too light, the preloading pressure will be insufficient, and the hardness at the pressing line of the paperboard will be added. In this way, it is easy to appear the phenomenon of internal strength and external weakness during molding, that is, because the strength of the corrugated paperboard and the corrugated paper kneading outward will become larger, forming the fiber of the paper in the drawing process, and then leading to the damage of the paper. If the same crimping trace is not obvious, the forming effect is even worse. If the pressure is increased only, the crimping trace is clear, but the bursting degree of the inner paper will increase.
在正常出产的情况下预压轮要正确的运用，预压的压力一定要满足不能过大或过小，预压轮压力一般操控在纸板厚度的一半左右为佳，压线的深*依据纸质进行恰当的调整。为更好的处理纸板爆线问题，可以依据本公司运用的纸张进行预压轮和压线轮的改造！如预压轮可以采用优力胶加钢制材料制作，也可以在预压轮上做压线凸点，能更好的辅佐压线作用。
Under the condition of normal production, the preloading wheel should be used correctly. The preloading pressure must not be too large or too small. The pressure of the preloading wheel is generally controlled at about half of the thickness of the paperboard, and the depth of the pressing line * should be properly adjusted according to the paper. In order to better deal with the problem of paperboard thread burst, the pre pressing wheel and thread pressing wheel can be transformed according to the paper used by the company! For example, the preloading wheel can be made of Youli rubber and steel materials, or the crimping convex point can be made on the preloading wheel, which can better assist the crimping effect.
一同，压线轮也是相同的改造形式：压线凸点的高度和宽度要适合本工厂的用纸情况，如工厂运用纸张低克重的比较多，那么压线轮的宽度就不能太窄，相对要宽一些。在印刷机的堆码机上加装一个喷雾设备，添加水分为了防止纸板制作的时分不爆线，出产完过了一段时间再爆线，可以在印刷机的堆码机上加装一个喷雾设备，对纸张进行喷雾。运用喷雾设备的时分要注意喷雾量和喷雾的方位。当然，防止纸箱爆线的方法还有很多种，如上水或加装预压轮等等，都是有用的操控纸板爆线的方向。在干燥的气候出产过程中，职工需求常常调查预压轮的压力及压线的压力，一同瓦线部位也要对纸板的水分进行恰当的操控。
At the same time, the crimping wheel is also the same transformation form: the height and width of the crimping bump should be suitable for the paper use of the factory. If the factory uses more paper with low gram weight, the width of the crimping wheel should not be too narrow, but relatively wider. Add a spray device on the stacker of the printing machine to add moisture. In order to prevent the line from exploding after a period of time, you can add a spray device on the stacker of the printing machine to spray the paper. When using spray equipment, pay attention to the spray amount and the spray direction. Of course, there are many ways to prevent carton burst, such as adding water or adding preloading wheels, which are useful to control the direction of carton burst. In the process of production in dry climate, employees often need to investigate the pressure of the preloading wheel and the pressure of the pressing line, and the moisture of the paperboard should also be properly controlled at the part of the tile line.
