1. Adjust the matching distance between the labeling cylinder and the stripping cylinder. Close the pneumatic valve, pull down the labeling cylinder to the limit position, and carefully observe the distance between the bottom surface of the suction head and the platform plane of the labeling cylinder. Adjust the position of the labeling cylinder according to the platform plane slightly lower than the bottom surface of the suction head. It can be adjusted up and down by loosening the fixing plate on the labeling cylinder. After adjustment, lock the fixing plate tightly.
2. Adjust the matching position between the stripping cylinder platform and the suction head. Cut off the pneumatic valve, pull out the label stripping cylinder, pull down the suction head, and carefully observe whether the position of the label absorbed by the suction head is basically pressed on the label stripping cylinder platform, and the label suction position can only cross the position where one label is covered. If most of the suction head's mark taking positions are not pressed on the platform, or two labels are pressed on the mark taking position, it should be adjusted according to the limit screw on the label stripping cylinder. If the adjustment range is relatively small, it can also be simply adjusted according to the front and rear positions of the adjustment suction head.
3. The label must be installed in place, and the label shall be wrapped neatly as far as possible, and it is easy to break the label if it is crooked. After the label is installed, fix the position with the stop ring.
4. Adjust the upper and lower cylinders for labeling. Place the product to be labeled on the fixture, close the pneumatic valve, pull down the labeling cylinder and labeling upper and lower cylinders to the limit position, and carefully observe whether the suction head can press the labeling position on the product surface. If the label position touching the product surface is not touched, adjust the fixing plate of the upper and lower cylinders of the label. It can be adjusted up and down after loosening the screw, and the adjustment completes the locking screw fixation. It can also be solved by raising the fixture platform. However, for different products, the pressing degree of the suction head will also be different. For example, for the more common planar label, the suction head only needs to touch the product surface (just in contact with the product surface) when pressing down; For some arc surface labeling, the pressing degree of the suction head requires a little more pressing and a little tighter pressing, so as to achieve the actual effect of complete label covering. Of course, for concave products, corresponding suction head clamps will be used for label attachment.
5. Adjustment of label stripping length. According to the size of different labels, the length of stripped labels is also limited. For larger labels, the length of the peeled out 1/3 is usually adjusted; For those with small labels, only 1~3mm edges need to be peeled. The label stripping length can be adjusted according to the spacing of the mobile marker eye. If the label stripping length is not enough, adjust the marker eye to the left (facing the display screen); If the label is too long, adjust the marker eye to the right.
6. Adjust the suction force. If the suction force is not enough, other unnecessary holes on the suction head can be blocked to increase the suction force at the suction position. The gap at the edge of the suction head can be wrapped with raw material tape to prevent some air leakage.
