Common troubles of plane labeling machine and its maintenance method

- Sep 29, 2019-

The flat labeling machine is a type of packaging machine, mainly a bottle cap or a straight bottle. Can be widely used in daily chemical, food, chemical and other industries. There are often problems in using the machine.

 

Adjustment of the brushing device

The center of the brush is aligned and symmetrical 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.

 

Label box adjustment

The center line of the standard box, the central axis of the standard station is tangent to the label paper, and the central axis of the target board is lined up at three points. The adjustment target board is tangent to the label paper (0 distance), and then the standard box is moved closer to 1 mm to 2 mm. The gap between the standard paper and the bead on both sides should be between 0.8mm-1mm. The gap is too large, causing the standard paper to shift in the standard box, and the skew 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, and 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 foremost end of the label box and the label near the label hook finger cannot be crushed.

 

Adjustment of the bottle into the star wheel,and the bottle screw

When adjusting the inlet and outlet star wheels and the feeding screw, the bottle 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. 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.

 

Adjustment of the standard station

Adjustment of the squeegee and the rubber roller: The squeegee and the rubber roller should not have a gap over the entire length. If there is a gap, the squeegee 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. If the gap is too large, there will be too much glue on the target board, 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.
