Labeling machines are widely used in various fields. Many manufacturers choose modern labeling machines to put labels on their products. However, many manufacturers are not familiar with machinery and learn to operate the labeling machine, but ignore the daily maintenance of the labeling machine.
Some tips for labeling machine maintenance can make the labeling machine perform better and prolong its service life.
First of all, the maintenance of the labeling machine must do a good job of cleaning. The labeling machine is easy to absorb dust during operation, so be sure to clean the dust on the labeling machine regularly.
When the labeling machine is temporarily idle, unplug the power supply and cover it with a dust cloth to prevent dust from falling on the labeling machine.
In addition, the high temperature belt of the labeling machine should be decontaminated regularly, so as to better ensure the high-quality operation of the labeling machine.
The automatic plane labeling machine will inevitably have some failures after being used for a long time, so how should we judge and repair it by ourselves? The following will share with you the common faults of the labeling machine and how to repair it.
1. Adjustment of the pressing brush device.
The center of the label brush is aligned with the label and symmetrical on both sides. The marker brush is perpendicular to the container surface.
The overlapping gap of the pressure brushes sweeping the container is as follows: a single pressure brush is 10mm to 15mm, and a combined pressure brush is 5mm to 10mm.
The position of the cleaning brush from the sponge is 1mm to 2mm. Adjustment of the bottle head. The bottle press 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 standard box, the central axis of the standard station and the label paper are tangent, and the three points of the central axis of the target plate are in a line, adjust the tangent between the target plate and the label paper (0 distance), and then move the standard box closer to 1mm ~ 2mm.
The gap between the standard paper in the standard box and the pressure bars on both sides should be between 0.8mm-1mm. If the gap is too large, the standard paper will be displaced in the standard box, and oblique marks will appear.
If the gap is too small, the standard push will be difficult. Adjustment of the position of the grabbing hooks of the standard box: the upper and lower, left and right grabbing hooks are on the same vertical plane and work evenly on the standard paper, so that the mark can be grasped smoothly.
Adjustment of the label feeding roller: When there is no label, the label pressing plate can be pressed to the front end of the label box and when the label is loaded, the label near the label hook finger cannot be crushed.
3. Adjustment of bottle feeding star wheel, bottle feeding star wheel and bottle feeding screw rod.
When adjusting the bottle-in, bottle-out star wheel and bottle-feeding screw rod, the bottle-pressing head of the labeling machine shall prevail. First adjust the bottle feeding star wheel.
When the bottle pressing head just presses the bottle, adjust the bottle feeding star wheel so that the bottle is located in the middle of the star wheel groove.
Adjustment of the bottle feeding screw: Take the bottle feeding star wheel as the criterion. When the bottle is in the middle of the groove of the bottle feeding star wheel, adjust the screw rod so that the bottle feeding side of the screw rod is close to the bottle without displacement.
Adjustment of the bottle star wheel: When the bottle press head is just lifted, adjust the star wheel so that the bottle is in the middle of the groove of the star wheel.
4. The adjustment of the standard station.
Adjustment of the rubber scraper and the rubber roller: There should be no gap between the rubber scraper and the rubber roller in the entire length.
If there is a gap, the rubber scraper can be adjusted by adjusting the eccentric bolt. Adjustment of the rubber roller and the target plate: The target plate and the rubber roller are only in contact with each other without any pressure. The gap is too large, and the glue on the target plate is too much, resulting in 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 gap between the target plate and the rubber roller is between 0.1mm and 0.2mm.
It can be achieved by adjusting the bearing seat on the lower part of the rubber roller, and if necessary, adjust the bearing on the upper part of the rubber roller.
