Double-sided labeling machine is suitable for labeling round, square and flat surfaces in medicine, daily chemical, food, stationery and other industries. Machines with more stable performance can also have one or another failures, but it can minimize the failure rate. After purchasing an ideal labeling machine, you should read the instructions carefully, install and operate in strict accordance with the instructions. In addition, regular maintenance should be carried out in future production, The following key points should be done well:
Attention of the labeling station: there should be no gap between the rubber scraper of the labeling machine and the rubber roller in the whole length. If there is a gap, the rubber scraper can be adjusted by adjusting the eccentric bolt. The marker plate and rubber roller only contact each other without any pressure. The gap is too large, and there is too much glue on the label plate, resulting in glue throwing. If the gap is too small and the contact is too tight, the glue will be squeezed out, and there is no glue on the half of the standard plate. Practice has proved that the clearance between the standard plate and the rubber roller is between 0.1 mm and 0.2 mm. This can be achieved by adjusting the bearing seat at the lower part of the rubber roll, and adjusting the bearing at the upper part of the rubber roll if necessary.
Attention of the label box in the labeling machine: the center line of the label box, the central axis of the label station and the label paper are tangent, the central axis of the label plate is in line at three points, adjust the tangent of the label plate and the label paper, and then move the label box closer to 1mm~2mm. The gap between the marker paper in the marker box and the strips on both sides should be between 0.8mm and 1mm. Too large gap will cause the marker paper to shift in the marker box, and there will be oblique marks. Too small gap will cause poor pushing of the marker.
Adjustment of the position of the mark grabbing hook of the mark box: if the upper, lower, left and right mark grabbing hooks are on the same vertical plane and work evenly on the mark paper, the mark can be grasped smoothly. Adjustment of the label supply roller: when there is no label, the label pressing plate can press to the front end of the label box and when there is a label, the label near the label hook finger cannot be damaged.
In addition, keep the working environment of the double-sided labeling machine clean and avoid dust, which can greatly extend the service life.
