1. Increase the viscosity of the label, make the label stick as firmly as possible, and achieve this expected effect, and fully consider the following aspects:

A. Control label pressure throughout the labeling process.

B. Control the ambient temperature throughout the labeling machine: Increasing the ambient temperature of the label will improve the expected effect of the label, because as the temperature increases, the charm of the internal structural chemicals of the item will also increase, and the logo will also It will be easier to integrate into the tube.

C. Improve the surface quality of plastic pipes: Most products have been coated on the surface, which will also increase the difficulty of labeling and leak the contents, which will also lead to the warping of the label.

2. Change the appearance of the label: Make the bottom end of the label into an arc and open the tail deformation area as much as possible. Of course, the arc cannot be opened too deep, otherwise wrinkles will easily be caused due to the identity itself, and excessive upgrades will be inconvenient. For special-shaped seals, the appearance of the label needs to be matched, which can not only avoid warping of the label but also increase the beauty of the form.

3. Hazards of static eliminator: The entire labeling process can easily cause needle tip discharge, that is, the expected effect of labeling will be destroyed. Properly increasing the relative humidity of the air at the labeling site will have certain improvement. Using ion fans is effective solution. The internal structure of the flat labeling machine is equipped with an air relative humidity control system, which can independently and automatically control the internal clean room level of the system. Let the labels of flat labeling machines avoid dust, improve the labeling quality of new products, and prevent the labels from warping during the labeling process, thereby achieving visual impact.

The labeling machine has adsorption effect, but does not absorb labels. It can be determined by the following methods:

1. First, look at the standard of the vacuum device

There are certain regulations on vacuum pump production standards, especially in terms of labeling machines. It not only pays attention to the adsorption force, but also pays attention to the time difference formed by the vacuum pump. If the mark is removed, it means that the vacuum pump has not been completed yet, which means that the vacuum pump is too late and the mark cannot be digested and absorbed, and the mark will fall off. If the vacuum pump is too long, it will cause a card mark. We should accurately adjust the time difference of such vacuum pumps.

2. Ask about auxiliary gas equipment, blowing check valve rods and blowing air holes

1. The time difference between auxiliary air blowing inspection should also be accurate, and some situations where the bottom is not sucked will occur too early or too late.

2. Too much or insufficient auxiliary blow inspection may cause stuck or off-label.

3. The purge check rod is free from dirt, and the blow holes have prefabricated components, so handle them in a timely manner. The logo adjustment may also fall in, so it must be maintained regularly.

3. Query the mark from the height of the board and palm

The relative height between the two must reach a moderate angle, which is not necessarily consistent. Regulation of label separation can be absorbed through digestion of labels. If the mark is too high, the mark will become detached and cannot be digested and absorbed, resulting in loss of the mark. If the mark is too low, card marks will also be caused. This requires moderate adjustments by everyone.
