              What are the reason for the precision of the die cutting

              DateTime:2020/05/16

              Many friends in the use of die-cutting machine, found that sometimes there will be precision decline, so what is the reason for this phenomenon? How can we solve this problem? The following xiaobian give you an analysis.

              One, the upper die - cutting or the lower die - cutting positioning is incorrect. The machine for a long time will cause die-cutting box or die-cutting bottom plate positioning block wear, so that the clearance is too large and lead to die cutting accuracy. The positioning block should be replaced. The wear of the side positioning plate is an important factor causing the inaccurate side positioning. Because the rotation of positioning is not enough to make up for the good wear, the side positioning accuracy will be poor. The side positioning plate should be replaced at this time.

              Second, the positioning distance of front and rear positioning pendulum frame is too small. Because the length of the chain itself has a certain error, if the positioning distance is too small, in front and rear positioning can not eliminate the chain error, thus affecting the precision of die-cutting. At this time should be adjusted before the positioning of the swing frame adjustment screw or after the positioning of the swing frame CAM position, so that the front and rear positioning frame can be rotated tooth row 2mm ~ 3mm distance is appropriate.

              Third, the paper teeth pressure is too small or uneven. If the paper teeth elastic activity due to long-term use and become smaller, it will cause the paper in the transfer process slip or fall off, thus directly affecting the die-cutting accuracy; Paper teeth between the pressure is not uniform may cause paper in the process of die - cutting skew. The removable teeth should be replaced at this point. In addition, fixed teeth should be consistent on the level, otherwise it is possible to produce paper collision or paper in its mouth after paper wrinkling, affecting the accuracy of die-cutting.

              Four, cardboard transfer process, the main transmission chain wear elongated, will directly affect the positioning accuracy before die-cutting. Change the chain at this point. Intermittent mechanism wear, causing teeth row in the process of stopping or starting jitter, will also affect the precision of die cutting. In this case, the positioning accuracy is generally only affected, at this point, it should be timely maintenance.

              The above four points are die-cutting precision is not high mechanical reasons, the need for operation and maintenance personnel to do a good job of maintenance of the machine, timely inspection and repair, in order to ensure the operation of die-cutting machine.
