不干胶加工中的会存在哪些疑难问题解答

来源:http://www.shengfengyinshua.com/ 日期:2021-05-07 发布人:admin 1.标签折叠不整齐的原因及解决办法
1. Causes and solutions of irregular folding of labels
导致标签折叠不整齐(的原因主要是设备张力问题。设备张力不稳定就会造成模切过程中模切刀的位置前、后摆动,从而导致折叠不整齐。这种原因导致的折叠不齐,折出来的标签呈锯齿状排列。遇到这种情况可以试着增加设备的运行张力,如果模切工位前面有压辊,一定要将压辊压上并保证压辊两边的压力一致。一般情况下经过以上调整可以解决这个问题,但如果还是不能解决,就需要请设备供应商协助解决。
The main reason for the irregular folding of the label is the tension of the equipment. The unstable tension of the equipment will cause the front and back swing of the die cutter in the process of die cutting, resulting in irregular folding. This causes uneven folding, folding out of the label zigzag arrangement. In this case, you can try to increase the running tension of the equipment. If there is a pressure roller in front of the die-cutting station, you must press the pressure roller and ensure that the pressure on both sides of the pressure roller is the same. In general, the above adjustment can solve this problem, but if it still can't be solved, we need to ask the equipment supplier for assistance.
2.标签折叠歪斜的原因及解决办法
2. Causes and solutions of label folding skew
标签折叠歪斜分两种情况,一种为前后歪斜,另一种为左右歪斜。前后歪斜一般是由于模切刀辊的直径与理论值有误差导致的。例如一个130齿的刀辊,直径理论上应该为412.75mm,但有的时候有误差,实际尺寸会比这个值大一些或者小一些。这样就会导致上面的折叠虚线刀不能均分,从而造成标签折叠后前后歪斜。
There are two kinds of label folding skew, one is front and back skew, the other is left and right skew. The front and back skew is generally caused by the error between the diameter of the die cutter roller and the theoretical value. For example, the diameter of a 130 tooth cutter roller should theoretically be 412.75mm, but sometimes there are errors, and the actual size will be larger or smaller than this value. This will result in the top of the folding line knife can not be evenly divided, resulting in label folding before and after skew.
左右歪斜一般是由于虚线刀歪斜导致的,有的时候折叠出现左右歪斜我们还能明显的看到虚线刀切出来是斜的。这时候只需要把虚线刀调正就可以了。但有一点需要注意,那就是有的时候我们肉眼观察虚线刀是正的,但实际切出来的标签却是斜的,出现这种情况有可能是设备的模切机组歪斜,或是模切刀辊歪斜。如果出现这种情况就需要对设备进行调整了。

The left and right skew is generally caused by the skew of the dotted line knife. Sometimes the folding appears left and right skew, and we can clearly see that the cutting of the dotted line knife is skew. At this time, you just need to adjust the dotted line knife. But there is one thing to note, that is, sometimes we visually observe that the dotted line knife is positive, but the actual cut out label is oblique. This situation may be caused by the skew of the die-cutting unit of the equipment or the skew of the die-cutting knife roll. If this happens, the equipment needs to be adjusted.
热熔胶材料冬季模切飞标
Hot melt adhesive material winter die cutting flying mark
热熔胶材料冬季的时候特别容易出现模切飞标的现象,所谓模切飞标就是在模切的时候标签会随着排废边被一同被掀起。如果出现较轻微的飞标现象,会给标签印刷企业造成一定的材料浪费;如果飞标比较严重,干脆就无法正常生产了。导致热熔胶材料冬季模切飞标的原因主要有以下几点。
Hot melt adhesive material in winter is particularly prone to die-cutting flymark phenomenon, the so-called die-cutting flymark is in die-cutting when the label will be lifted with the waste edge. If there is a slight phenomenon of flymark, it will cause certain material waste to label printing enterprises; If the flying buoy is serious, it will not be able to produce normally. Lead to hot melt adhesive material winter die-cutting flymark the main reasons are as follows.
1.热熔胶受温度影响离型力降低
1. The release force of hot melt adhesive is reduced due to the influence of temperature
热熔胶不干胶材料有一个特性就是受温度影响较大,一般情况下,车间温度低于15℃时,热熔胶材料的离型力会迅速降低。因此在我国北方的冬季,热熔胶材料特别容易出现模切飞标的问题。
One of the characteristics of hot-melt adhesive materials is that it is greatly affected by temperature. Generally, when the workshop temperature is lower than 15 ℃, the release force of hot-melt adhesive materials will decrease rapidly. Therefore, in the winter of northern China, hot melt adhesive material is particularly prone to die-cutting flying mark problem.
2.热熔胶本身离型力偏低
2. The release force of hot melt adhesive is low
如果热熔胶本身离型力就偏低,那么在夏季模切可能没有问题,但在冬季就很容易出现模切飞标的问题。
If the hot melt adhesive itself on the low release force, then there may be no problem in summer die-cutting, but in winter it is easy to die-cutting flying beacon problem.
3.胶水拉丝、回流
3. Glue drawing and reflow
热熔胶还有一个特性是流动性强,在正常温度下进行模切,热熔胶比水胶更容易拉丝和回流。换句话说就是热熔胶更容易与排废边粘连,从而导致飞标。
Another characteristic of hot melt adhesive is its strong fluidity. It is easier to draw and reflow than water adhesive when die cutting at normal temperature. In other words, the hot melt adhesive is more likely to adhere to the waste edge, which leads to flying mark.
