          不干膠加工中的會存在哪些疑難問題解答

          來源:http://www.apersianrug.com/ 日期:2021-05-07 發布人:admin 1.標簽折疊不整齊的原因及解決辦法
          1. Causes and solutions of irregular folding of labels
          導致標簽折疊不整齊(的原因主要是設備張力問題。設備張力不穩定就會造成模切過程中模切刀的位置前、后擺動,從而導致折疊不整齊。這種原因導致的折疊不齊,折出來的標簽呈鋸齒狀排列。遇到這種情況可以試著增加設備的運行張力,如果模切工位前面有壓輥,一定要將壓輥壓上并保證壓輥兩邊的壓力一致。一般情況下經過以上調整可以解決這個問題,但如果還是不能解決,就需要請設備供應商協助解決。
          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.標簽折疊歪斜的原因及解決辦法
          2. Causes and solutions of label folding skew
          標簽折疊歪斜分兩種情況,一種為前后歪斜,另一種為左右歪斜。前后歪斜一般是由于模切刀輥的直徑與理論值有誤差導致的。例如一個130齒的刀輥,直徑理論上應該為412.75mm,但有的時候有誤差,實際尺寸會比這個值大一些或者小一些。這樣就會導致上面的折疊虛線刀不能均分,從而造成標簽折疊后前后歪斜。
          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虛線刀歪斜導致的,有的時候折疊出現左右歪斜我們還能明顯的看到虛線刀切出來是斜的。這時候只需要把虛線刀調正就可以了。但有一點需要注意,那就是有的時候我們肉眼觀察虛線刀是正的,但實際切出來的標簽卻是斜的,出現這種情況有可能是設備的模切機組歪斜,或是模切刀輥歪斜。如果出現這種情況就需要對設備進行調整了。

          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.
          熱熔膠材料冬季模切飛標
          Hot melt adhesive material winter die cutting flying mark
          熱熔膠材料冬季的時候特別容易出現模切飛標的現象,所謂模切飛標就是在模切的時候標簽會隨著排廢邊被一同被掀起。如果出現較輕微的飛標現象,會給標簽印刷企業造成一定的材料浪費;如果飛標比較嚴重,干脆就無法正常生產了。導致熱熔膠材料冬季模切飛標的原因主要有以下幾點。
          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.熱熔膠受溫度影響離型力降低
          1. The release force of hot melt adhesive is reduced due to the influence of temperature
          熱熔膠不干膠材料有一個特性就是受溫度影響較大,一般情況下,車間溫度低于15℃時,熱熔膠材料的離型力會迅速降低。因此在我國北方的冬季,熱熔膠材料特別容易出現模切飛標的問題。
          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.熱熔膠本身離型力偏低
          2. The release force of hot melt adhesive is low
          如果熱熔膠本身離型力就偏低,那么在夏季模切可能沒有問題,但在冬季就很容易出現模切飛標的問題。
          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.膠水拉絲、回流
          3. Glue drawing and reflow
          熱熔膠還有一個特性是流動性強,在正常溫度下進行模切,熱熔膠比水膠更容易拉絲和回流。換句話說就是熱熔膠更容易與排廢邊粘連,從而導致飛標。
          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.
