With the development of society and the continuous improvement of consumption levels, consumers' external requirements for bottled drinks are also constantly improving. The labeling machine is the main equipment for the beer filling production line, which plays a key role in the outer packaging of the beer production process. Through the author's years of experience in the actual maintenance of the labeling machine and the in-depth analysis of the labeling principle, the adjustment of the labeling machine is summarized, and it is hoped that the operator of the labeling machine will be helpful.

1. Adjustment of the bottle star wheel, the bottle star wheel, and the bottle screw.
(1) When adjusting the inlet and outlet star wheels and the feeding screw, the pressure head of the labeling 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;
(2) 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.
(3) Adjustment of the bottle star wheel: When the bottle head is just lifted, adjust the star wheel so that the bottle is in the middle of the groove of the star wheel.
2. Adjustment of the label box
(1) The center line of the standard box, the central axis of the labeling station is tangent to the label paper, and the central axis of the labeling 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 to 2 mm. can;
(2) The gap between the label box and the two sides of the strip should be between 0.8mm~1mm. The gap is too large, causing the label paper to shift in the label box, and the skew mark appears. If the gap is too small, the push mark will be unsatisfactory;
(3) 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, then the label can be smoothly captured;
(4) Adjustment of the label supply roller: When there is no label, the label platen can be pressed to the foremost end of the label box and when the label is mounted, the label near the label hook finger cannot be crushed.
3. Adjustment of the brushing device
(1) The center of the label is aligned and the two sides are symmetrical;
(2) the label brush is perpendicular to the surface of the container;
(3) 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;
(4) The position of the cleaning brush from the sponge is 1 mm to 2 mm.
4. Adjustment of the pressure head
The bottle head should be 20mm lower than the bottle when there is no bottle.
5. Adjustment of the standard station
(1) Adjustment of the squeegee and the rubber roller: the squeegee and the rubber roller should not have a gap in the whole length. If there is a gap, the squeegee can be adjusted by adjusting the eccentric bolt;
(2) 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.
6. Adjustment of the scaler
(1) Adjustment of the finger: The finger must be parallel to the finger pad and must not exceed the edge of the finger pad and be flush with the edge of the finger pad. The finger must be in a horizontal position and at the center of the marker groove. The size of the clip finger clip is: the body mark is not less than 5mm, and the aluminum foil label is not less than 7mm. It is necessary to ensure that the body mark and the center line of the head mark are in a straight line after taking the mark;
(2) Adjustment of the pinch tension: When the pinch of the indexer is clamped on the pad (the standard can not be extracted), the pin finger cannot exceed the finger pad and should be flush with the finger pad. The dimensions of the guide wheel and cam: 13mm for the body and 22mm or 28mm for the head. The fingers on each shaft should be pressed evenly on the finger pad;
(3) Adjustment of the finger pad: The finger pad should be parallel with the palm of the hand, and the gap between the body clip finger pad and the palm is 1.0mm~1.5mm. When attaching the aluminum foil, the gap between the finger pad and the palm should be less than 1mm. Adjustment: Continuous slow stepping car, until the center of the turret and the front edge of the standard paper and the center of the scaler are on the same line. Manually rotate the indexer in the opposite direction of the running direction until the finger pad is accurately 4mm to 5mm, so that the target and the finger pad can achieve a small end gap. At this time, loosen the connecting bolt of the finger pad and adjust it as follows: the finger pad is parallel to the target, the gap between the finger pad and the target is 1mm and the other finger pad is adjusted in the same way;
(4) Adjustment of the tapping device sponge: The sponge bevel should be installed on the side of the finger pad. The width of the sponge should be smaller than the size of the standard paper, and the height should be larger than the size of the standard paper. The thickness of the sponge should not exceed the height of the finger pad and must never be tangent to the palm. After the clip of the scaler is clamped, the center line of the label should be on the same line as the center line of the sponge;
(5) Adjustment of sponge pressure: When the container, the take-up shaft and the central axis of the machine head become a straight line, adjust the cross slide until the sponge is pressed into about 10mm (body standard), and the head mark is pressed into 4mm~5mm. .
(6) Adjustment of the finger closing point:
1 The turret center of the target board, the edge of the target board and the axis of the indexer are on the same straight line, the finger pad is 4mm~5mm, the finger pad is parallel to the target and the gap with the target is about 1mm;
2 In this position, the finger should be closed and without any tension, the guide wheel is located at the convex part of the cam;
3 If this is not the case, re-adjust the scaler, remove the cover, loosen the hexagon socket head bolts, turn the closing cam until the fingers are properly in contact with the finger pad, retighten the bolts that close the cam, and close Mark the location.
(7) Adjustment of the finger opening point:
1 when the center of the machine, the center of the container, the center of the label, and the center of the scaler axis become a straight line, the finger is opened;
2 Jog the machine until the above points are aligned, loosen the hexagon socket head bolts, turn the open cam until the finger is opened to the maximum position, and the guide wheel is at the concave part of the cam;
3 When performing this operation, make sure that the back end of the closing cam and the front end of the opening cam are directly in the up and down position;
4 Keep “open the cam in this position, adjust the closing cam to the previous mark, and tighten the hexagon socket head boltâ€.
