Labeling machine repair requires several steps-industry news

Precautions for the maintenance of the labeling machine: 1. Adjustment of the pressure brush device: The center of the brush is aligned with the label and the two sides are symmetrical. The marking brush is perpendicular to the surface of the container. The overlap gap of the pressure brush sweeping the container is: a single pressure brush is 10mm-15mm, and a combined pressure brush is 5mm-10mm. The distance between the cleaning brush and the sponge is 1mm~2mm. Adjustment of the pressure bottle head. The pressing head should be 20mm lower when there is no bottle than when there is a bottle. 2. Adjustment of the label box: The center line of the label box, the central axis of the label station is tangent to the label paper, and the central axis of the label plate forms a line at three points. Adjust the tangency of the label plate and the label paper (0 distance), and then move the label box closer. 1mm～2mm is enough. The gap between the label paper in the label box and the pressing strips on both sides should be between 0.8mm-1mm. If the gap is too large, the label paper will be shifted in the label box and oblique marks will appear. If the gap is too small, it will cause poor label push. Adjustment of the position of the label-grabbing hooks of the label box: the upper, lower, left and right label-grabbing hooks are on the same vertical plane and evenly work hard on the label paper, so that the label can be grasped smoothly. Adjustment of the label supply roller: When there is no label, the label pressing plate can be pressed to the front end of the label box and the label near the label hook finger cannot be crushed. 3. Adjustment of the bottle inlet star wheel, bottle outlet star wheel and bottle inlet screw rod: When adjusting the bottle inlet and outlet star wheel and bottle inlet screw rod, use the bottle pressing head of the labeling machine (printing labeling machine) as allow. First, adjust the bottle inlet star wheel. When the bottle pressing head just overwhelms the bottle, adjust the bottle inlet star wheel so that the bottle is in the middle of the star wheel groove. Adjustment of the bottle feeding screw: take the bottle feeding star wheel as the standard. When the bottle is in the middle of the groove of the bottle feeding star wheel, adjust the screw rod so that the bottle inlet side of the screw is close to the bottle without displacement. Adjustment of the bottle-out star wheel: When the bottle pressing head is just raised, adjust the star wheel so that the bottle is in the middle of the groove of the star wheel. 4. Adjustment of the squeegee and the rubber roller: There should be no gap between the squeegee and the rubber roller in the entire length. If there is a gap, the squeegee can be adjusted by adjusting the eccentric bolt. The adjustment of the rubber roller and the standard plate: the standard plate and the rubber roller are only in contact with each other without any pressure. The gap is too large and there is too much glue on the target plate, causing glue rejection. If the gap is too small and the contact is too tight, the glue will be squeezed away, and there is no glue on the half of the target board. Practice has proved that the best gap between the standard plate and the rubber roller is between 0.1mm and 0.2mm. This can be achieved by adjusting the bearing seat at the lower part of the rubber roller, and if necessary, adjust the bearing on the upper part of the rubber roller.
