1, first of all to confirm what color group sticky paper, there is no law to follow.
2, if it is a single color group, to see if the position is fixed, if the fixed is mostly due to the impression roller or the post-feed roll (or tooth pad) wear, resulting in bite paper or tooth rust rusty teeth resulting in dead teeth The reason for this is that the paper was transferred over a long time and the tearing of the paper caused it.
Solution: Increase the pressure on the tooth; move the tooth hoops; replace the pad; recalibrate the transfer time as required by the standard.
3, if it is a few color groups have different degrees of sticky paper (especially the third and fourth color group majority), and the location is not fixed, most of it is due to a bad paper feed (mostly paper is not in place); Or positioning and transfer time is too short; the other is the transfer of paper teeth and roller exchange paper when there is out of control;
Remedy: Recalibrate feeder feeding timing, ensure that the timing of flipper and pick-up roller are correct, and confirm the positioning device and the transfer bar section, when the paper reaches the front gauge, and when the pull gauge is actuated There is a strict degree limit on when the paper teeth row is to be taken and when it is handed over.
4. If only the fourth group of sticky tapes is sticky, most of them are caused by the wear and tear of the tooth pad of the collection tooth, resulting in the inability to bite the teeth; in addition, the position (or time) of the delivery tooth row and the stamping four is not correct. cause.
Remedy: Check and level the force of the feed-receiving row; confirm the transfer time between the delivery row and the embossed four.
