Labeller is a device that attaches paper or metal foil labels to a specified packaging container with an adhesive. Labeling machines are an integral part of modern packaging. At present, the types of labeling machines in China are gradually increasing, and the technical level has also been greatly improved. From the backward situation of manual and semi-automatic labeling, the automatic high-speed labeling machine has occupied the market.
Maintenance of labeling machine 1. Adjustment of bottle into star wheel, bottle star wheel and bottle screw (1) When adjusting the inlet and outlet star wheel and the feeding screw, press the bottle head of the labeling machine Prevail. First adjust the bottle into the star wheel, when the bottle head just overwhelm the bottle, adjust the bottle into the star wheel, so that the bottle is in the middle of the star wheel groove;
(2) Adjustment of the inlet screw: According to the inlet star wheel, when the bottle is in the middle of the groove of the inlet star wheel, adjust the auger so that the auger is pressed against the bottle side without displacement.
(3) Adjustment of the bottle star wheel: When the bottle head is just lifted, adjust the star wheel so that the bottle is in the middle of the groove of the star wheel.
2. Adjustment of the label box (1) The center line of the label box, the central axis of the label station is tangent to the label paper, and the center axis of the label board is lined up at three points. The adjustment target board is tangent to the label paper (0 distance), and then the label box Move closer to 1mm ~ 2mm;
(2) The gap between the label box and the two sides of the strip should be between 0.8mm-1mm. The gap is too large, causing the label paper to shift in the label box, and the skew mark appears. If the gap is too small, the push mark will be unsatisfactory;
(3) Adjustment of the position of the labeling hook of the standard box: the upper and lower and the left and right grasping hooks are on the same vertical plane and evenly work on the standard paper, then the label can be smoothly captured;
(4) Adjustment of the label supply roller: When there is no label, the label platen 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 brushing device (1) The center of the labeling brush is aligned with the label and the two sides are symmetrical;
(2) the label brush is perpendicular to the surface of the container;
(3) The overlapping gap of the brushing sweeping container is: a single pressing brush is 10 mm to 15 mm, and the combined pressing brush is 5 mm to 10 mm; (4) the cleaning brush is located at a distance of 1 mm to 2 mm from the sponge.
4. The adjustment of the pressure bottle head should be 20mm lower than when there is a bottle.
5. Adjustment of the standard station (1) Adjustment of the squeegee and the rubber roller: the squeegee and the rubber roller should not have a gap in the whole length. If there is a gap, the squeegee can be adjusted by adjusting the eccentric bolt;
(2) Adjustment of the rubber roller and the target plate: the target plate and the rubber roller only contact each other without any pressure. If the gap is too large, the glue on the label will be too much, 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 bearing housing in the lower part of the rubber roller and adjusting the bearing on the upper part of the rubber roller if necessary.
