一般我們把瓦楞紙板折痕線部位在加工、折疊、裝箱及堆垛時出現(xiàn)的面里紙爆裂的現(xiàn)象稱為爆線。瓦楞紙板爆線會影響紙箱的空箱抗壓值，相同也會影響紙箱的外觀，是困擾紙板出產(chǎn)的嚴(yán)峻質(zhì)量缺陷之一。材料、環(huán)境、設(shè)備、操作方法等都會形成紙板爆線大多數(shù)紙板質(zhì)量問題的產(chǎn)生原因一般都是多方面的，爆線也是如此。其本源觸及材料、環(huán)境、設(shè)備、操作方法等各大要素。紙箱爆線類型分為幾種，一種是里紙爆線，還有一種就面紙爆線
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
其間紙箱面紙爆線主要原因：1壓線壓力調(diào)整不妥2、紙板水分太低處理紙箱面紙爆線要從以下方面多做改進：印刷壓線必求深：印刷機在出產(chǎn)過程中由于壓線壓力過重易導(dǎo)致印刷爆線。如果將預(yù)壓輪壓重，紙箱不爆線，可是紙箱成型就欠好，紙箱四邊出現(xiàn)圓角現(xiàn)象。紙箱壓線太淺紙箱成型就會形成剪刀差，接縫巨細(xì)等現(xiàn)象，所以壓線就必求深。
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.
預(yù)壓輪壓力：操控在紙板厚度的一半左右為佳印刷機的壓線部分為預(yù)壓輪（壓潰輪）和壓線輪組成。如果壓潰輪的壓力調(diào)整過輕，那么預(yù)壓的壓力就不足，紙板壓線處的硬度就會添加，這樣成型時易出現(xiàn)內(nèi)強外弱的現(xiàn)象，也就是由于瓦楞紙板里紙加瓦紙向外揉捏的強度就會變大，形成面紙在拉伸過程中紙的纖維出現(xiàn)開裂，然后導(dǎo)致面紙破損。相同壓線痕跡不明顯，成型作用就更差，如單單把壓線壓力加大，壓線痕跡是清晰的，可是里紙爆裂的程度就會加大。
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.
在正常出產(chǎn)的情況下預(yù)壓輪要正確的運用，預(yù)壓的壓力一定要滿足不能過大或過小，預(yù)壓輪壓力一般操控在紙板厚度的一半左右為佳，壓線的深*依據(jù)紙質(zhì)進行恰當(dāng)?shù)恼{(diào)整。為更好的處理紙板爆線問題，可以依據(jù)本公司運用的紙張進行預(yù)壓輪和壓線輪的改造！如預(yù)壓輪可以采用優(yōu)力膠加鋼制材料制作，也可以在預(yù)壓輪上做壓線凸點，能更好的輔佐壓線作用。
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，壓線輪也是相同的改造形式：壓線凸點的高度和寬度要適合本工廠的用紙情況，如工廠運用紙張低克重的比較多，那么壓線輪的寬度就不能太窄，相對要寬一些。在印刷機的堆碼機上加裝一個噴霧設(shè)備，添加水分為了防止紙板制作的時分不爆線，出產(chǎn)完過了一段時間再爆線，可以在印刷機的堆碼機上加裝一個噴霧設(shè)備，對紙張進行噴霧。運用噴霧設(shè)備的時分要注意噴霧量和噴霧的方位。當(dāng)然，防止紙箱爆線的方法還有很多種，如上水或加裝預(yù)壓輪等等，都是有用的操控紙板爆線的方向。在干燥的氣候出產(chǎn)過程中，職工需求常常調(diào)查預(yù)壓輪的壓力及壓線的壓力，一同瓦線部位也要對紙板的水分進行恰當(dāng)?shù)牟倏亍?/div>
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.
