1. Adjusting of the scraping rubber sheet and the rubber roller: the cold glue labeling machine scraping rubber sheet and the rubber roller can not have a gap in the whole length. If there is a gap, the offset rubber plate can be adjusted by adjusting the eccentric bolt;
2. Adjustment of the rubber roller and the target plate: the wet glue labeling machine label and the rubber roller only contact each other without any pressure. If the gap is too large, there will be too much glue on the target board, causing the glue. The gap is too small, the contact is too tight, the glue will be squeezed away, and there is no glue on the half of the target. Practice has proved that the gap between the target plate and the rubber roller is between 0.1mm and 0.2mm. This can be achieved by adjusting the housing on the lower part of the rubber roller and adjusting the bearings on the upper part of the rubber roller if necessary.
