1. From the end of the 1980s to 1994, it was the * stage. This stage is mainly to introduce and imitate the labeling machine that has been eliminated in foreign countries. At that time, several labeling machine manufacturers could only produce labeling machines with two labels (neck and body standard). Due to the gap between the functions, performance, appearance and labeling quality of domestically produced equipment compared with imported equipment, this period is too wide. Imported labeling machines dominate the Chinese market, and most manufacturers still choose to import labeling machines.
Second, from 1995 to 2001 is the second phase. This stage is the upgrading stage of the production of Chinese labeling machines. First, the labeling speed is increased from 24,000 bottles/hour to 33,000 bottles/hour. The second is the improvement of the labeling function, from the labeling of the two labels (neck and body) to the labeling of the four labels. Can be attached to the head, neck, body, and back.
Third, from 2002 to the present is the third stage. This stage is a mature stage of China's labeling machine technology and a major turning point in the history of China's labeling machine. In the past four years, the manufacturers of domestic labeling machines have competed with each other, and they have also formed a situation of competition with foreign labeling machine manufacturers. They are improving in competition, developing in development, innovating in development, and growing in innovation. , gradually completed a "quality" leap.
Maintenance tips for labeling machines :
1. Adjusting the scraping plate and rubber roller of the standard station: The scraping rubber plate and the rubber roller should not have gaps in the whole length. If there is a gap, the squeegee plate can be adjusted by adjusting the eccentric bolt. 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.
2. The center line of the label box is adjusted. The center axis of the label station is tangent to the label paper. 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 is moved closer to 1 mm. ~2mm can be. The gap between the standard paper and the bead on both sides should be between 0.8mm and 1mm. The gap is too large, causing the standard paper to shift in the standard box, and the oblique mark appears. If the gap is too small, the push mark will be poor. The 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, so that the label can be smoothly captured. 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 bottle star wheel, the bottle star wheel, and the bottle screw. When adjusting the inlet and outlet star wheels and the bottle screw, the pressure bottle head of the standard machine shall 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. 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. Adjustment of the bottle star wheel: When the bottle head has just been lifted, adjust the star wheel so that the bottle is in the middle of the groove of the star wheel.
4. The center of the adjustment brush of the brushing device is aligned with the label and symmetric on both sides. The brush is perpendicular to the surface of the container. 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. The position of the cleaning brush from the sponge is 1 mm to 2 mm. Adjustment of the bottle head. The bottle head should be 20mm lower than the bottle when there is no bottle.
