  How to deal with the hole position deviation of transparent adhesive label drum?
  济南不干胶印刷纸卷印刷技术广泛应用于快递票据的印刷。快递单的底部是用不干胶纸做的。快递运单底部采用无碳复写纸作为纸巾,底部采用自粘纸,再将自粘纸组合成自粘纸卷,然后在纸卷上打印孔和打印条码。较后,将论文与上下两页进行匹配,完成快递运单的制作。打孔胶粘纸在卷绕过程中,靠近纸芯管时,往往会出现纸张两侧和底部孔位移问题,造成孔位不均匀。当孔位偏差超过0.5mm时,页面无法与上下部分连接,造成较大损失。
  Jinan non-adhesive printing paper roll printing technology is widely used in express bills printing. The bottom of the express bill is made of adhesive paper. Carbon-free copy paper is used at the bottom of express waybill as paper towel, self-adhesive paper is used at the bottom, then self-adhesive paper is combined into self-adhesive paper roll, and then holes are printed on the paper roll and barcode is printed. Finally, the paper is matched with the upper and lower pages to complete the production of express waybill. During the winding process of perforated adhesive paper, when it is near the paper core tube, the displacement of holes on both sides and at the bottom of the paper often occurs, resulting in the uneven location of holes. When the hole position deviation exceeds 0.5 mm, the page can not be connected with the upper and lower parts, resulting in greater losses.

  在不干胶纸卷筒纸印刷过程中,采用在线打孔的方法。平孔完成后,将面纸向外卷起,底纸向内卷起。卷绕时,由于卷筒纸的厚度不同,卷筒纸与底纸的卷筒半径略有不同,产生圆周差,如图1所示。同时,在卷绕张力的作用下,薄纸和基纸产生伸长变形。由于受圆周差的影响,薄纸的伸长率大于基纸,用这种差值来减小圆周差。作为一种自粘纸,组织纸与底纸之间的结合力很小,当伸长率的差异不能完全抵消周长的差异时,组织纸与底纸产生相对运动,初始对准孔的位置发生偏移。R外纸卷绕半径R内底纸卷绕半径h非1000橡胶纸厚度图1表面纸与底纸卷绕圆周差示意图

  In the process of non-dry offset web printing, on-line punching method is adopted. When the flat hole is finished, roll the face paper outward and the bottom paper inward. When winding, because of the different thickness of web paper, the radius of web paper is slightly different from that of base paper, resulting in circumference difference, as shown in Figure 1. At the same time, under the effect of winding tension, thin paper and base paper produce elongation deformation. Due to the influence of circumference difference, the elongation of thin paper is larger than that of base paper, and this difference is used to reduce circumference difference. As a kind of self-adhesive paper, the bonding force between tissue paper and base paper is very small. When the difference of elongation cannot completely offset the difference of perimeter, the relative motion between tissue paper and base paper occurs, and the position of initial alignment hole is offset.

  二、孔位偏差尺寸分析滚筒胶粘纸孔位偏差尺寸由内外径、圆周差和纸张伸长量决定。绕组内部和外部直径圆周不同粘合剂的底部和发布论文的单张纸穿孔,孔间距是一样的,但是在复合线圈、防粘纸里面,外面的胶粘剂,区别在一个圆的周长。这种差别与纸卷的半径大小无关。半径由脱模纸厚度中心线和胶粘底线计算。
  2. Hole position deviation size analysis The hole position deviation size of drum adhesive paper is determined by inner and outer diameter, circumference difference and paper elongation. The bottom of different adhesives with inner and outer diameters of the winding and the paper sheet are perforated with the same hole spacing, but inside the composite coil and anti-sticking paper, the outside adhesives are different from the circumference of a circle. This difference has nothing to do with the radius of the paper roll. The radius is calculated by the center line of stripping paper thickness and the adhesive bottom line.
