How does the hot melt adhesive labeling machine label?

In recent years, the gradual expansion of the packaging industry has brought the entire packaging industry into a normal state. Hot melt adhesive labeling machines are commonly used labeling equipment in the packaging industry and are favored by many packaging industries, especially the food industry. Let's take a look at how the hot melt adhesive labeling machine marks this problem.

The labeling of the hot melt adhesive labeling machine is inseparable from the cooperation of the labeling box, labeling station, and pressure brush device.

The adjustment of the position of the label catching hook in the label box is that the upper, lower, left and right label catching hooks are on the same vertical plane and work evenly on the label paper, and then the label can be successfully captured. The gap between the label paper in the label box and the pressure strips on both sides should be between 0.8mm and 1mm. A too large gap will cause the label paper to move in the label box, and slanted labels will appear, and a too small gap will cause the label to be pushed. Not smooth. The center line of the label box and the center axis of the label station are tangent to the label paper. The central axis of the label plate forms a line at three o'clock. The label plate is adjusted to be tangent to the label paper, and then the label box is moved closer 1mm to 2mm. 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. When installing the label, the label near the label hook finger will not be squeezed.

For the adjustment of the rubber roller and the label plate, the label plate and the rubber roller only contact each other without any pressure. If the gap is too large, too much glue on the label board will cause the glue to be thrown out. If the gap is too small and the contact is too tight, the glue will be squeezed out. Adjustment of rubber scraper and rubber roller: There should be no gap between the rubber scraper and the rubber roller over the entire length. If there is a gap, the rubber scraper can be adjusted by adjusting the eccentric bolt. Practice has proved that the gap between the label plate and the rubber roller is preferably between 0.1 mm and 0.2 mm. This can be achieved by adjusting the bearing seat at the lower part of the rubber roller and adjusting the bottle pressing head if necessary. When there is no bottle, the pressing head should be 20mm lower than when there is a bottle. The overlap gap between the pressure brushes sweeping the container is 10 mm to 15 mm for a single pressure brush and 5 mm to 10 mm for a combined pressure brush. The distance between the cleaning brush and the sponge is 1 mm to 2 mm. The center of the brush is aligned with the label, and the two sides are symmetrical. The brush is perpendicular to the surface of the container.
