Flat labeling machine is a type of packaging machinery, mainly for caps or straight-faced bottles. It can be widely used in daily chemical, food, chemical and other industries. Some problems often occur during the use of the machine
1. Adjustment of 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 label box
The center line of the label box, the center axis of the label station is tangent to the label paper, and the center 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 to 1mm~2mm. The gap between the label paper in the label box and the pressing strips on both sides should be between 0.8mm-1mm. Too large the gap will cause the label paper to shift in the label box, and there will be oblique marks. 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, then 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 is installed, the label near the label hook cannot be crushed.
3. Adjustment of the bottle-in star wheel, the bottle-out star wheel, and the bottle-in screw rod
When adjusting the bottle inlet and outlet star wheel and the bottle inlet screw rod, the press head of the standard machine shall prevail. First adjust the bottle-in star wheel. When the bottle pressing head just overwhelms the bottle, adjust the bottle-in 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 standard station
The 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.
