I. Pre-Startup Preparation
1. Check the cleanliness of the workroom, remove any excess items, and check that the labeling machine displays the "Clean" status indicator.
2. Adjust the distance between the peel plate and the bottle to 1.5–3 mm. Too close will cause friction between the label backing and the bottle, causing the label to break. Too much distance will prevent the label from being properly applied to the bottle.
3. Adjust the distance between the label roller and the peel plate to 1.5–3 mm. This is primarily to prevent the label roller from rolling on the label when the label is not being applied.
4. Use the bottle to check the tightness between the label roller and the bottle. Ideally, the bottle should be pressed firmly enough to fit in. If too loose or too tight, adjust the label stopper and the lifting wheel of the label roller mounting bracket. 5. Place the label paper onto the label roller and pass it through the printer's ribbon, groove sheet, electric probe, peel plate, and pressure roller in sequence. After all adjustments are complete, turn on the machine. Check the water and electricity switches and supply status.
II. Turning On the Machine:
1. Turn on the power; the indicator light will illuminate.
2. Set the printer's heating element to high setting. After 3-6 minutes, when the batch number is clearly visible, adjust the knob to setting 2 and follow the standard operating procedures for thermal printers.
III. Checking the Sensitivity of the Photoelectric Head
1. Check the photoelectric detector on the bottle labeler by shaking it with a barrier 5-10 mm from the head. If two or more marks appear after shaking, the sensitivity is high. If only one mark appears after shaking several times, the sensitivity is low. Adjust the potentiometer knob accordingly. 2. Check the label photoelectric detector. Observe that the distance between the label and the peel plate should be 1-3mm, ensuring that the bottle does not come into contact with the label when passing through. If the distance is not correct, adjust the potentiometer knob. If adjustment is not adequate, adjust the distance between the groove photoelectric head and the two labels.
3. After the above adjustments are normal, place the bottles to be labeled on the bottle feed turntable. Adjust the conveying and bottle separation speed knobs in sequence. Then, adjust the label feed speed knob to levels 3-4 and the labeling speed knob to levels 5-6.
4. Check the labeling process. If there are problems such as labels being connected or the paper being torn, adjust the conveying, label feed, and labeling speeds.
IV. Precautions for Operating the Fully Automatic Labeling Machine:
1. While the machine is running, do not manually check for missing labels to avoid pressing your hand into the labeling roller.
2. When the printer heater knob reaches a sufficient temperature, turn it to a lower setting to avoid damaging the printer's heating system due to excessive preheating time. 3. If you need to change the batch number during operation, use tweezers to grasp the batch number to avoid injury.
This concludes today's discussion on the necessary inspections before and after using the self-adhesive labeling machine to prevent errors. I hope this will be helpful for your future use of this equipment.
