How to deal with the phenomenon of label warping in Sichuan self-adhesive labeling machine-industry news
by：Zhongya Packaging 2022-05-30
The self-adhesive labeling machine is an automatic packaging machine that uses a self-adhesive roll of label paper. During the automatic bottle feeding process with a bottle unscrambler, the roll of label paper is continuously torn off and attached to the bottle body according to the required position. The equipment control system uses computer programming and full Chinese LCD touch screen, text type and button type. It is a modern mechatronics product with excellent and reliable working performance. The self-adhesive labeling machine has the advantages of cleanliness, sanitation, no mold, beautiful appearance, firmness after labeling, and high production efficiency. A visual effect should be achieved in labeling. One of them is to avoid the phenomenon of label warping in labeling. Label the tube before it is filled, and then fill and seal the tube after it is labeled. The heating during the sealing process is particularly severe to the label. The closer the label is to the bottom, the greater the possibility of label warping. In practical applications, almost every manufacturer has similar problems, and there are various solutions. Today, the editor also combines the experience gained from using this equipment for many years to share with you. (1), increase the viscosity of the label, try to make the label stick firmly. To achieve this effect, the following aspects need to be considered: ①Improve the surface quality of the hose being pasted. The surface of most products has varnish, which will increase the difficulty of labeling. The leakage of the content, the micropores in the tube wall, etc. will cause the label to lift. How to avoid such problems should be considered by everyone. A more important question. ②Control the labeling pressure during the labeling process. ③Control the temperature during the labeling process. Increasing the labeling temperature will improve the labeling effect, because as the temperature rises, the activity of the substance inside the object will increase, and the label will be more easily integrated with the tube body. (2) Use soft label materials as much as possible, and good label ductility will greatly improve label warping. (three), change the shape of the label. Make the bottom of the label into an arc shape, try to avoid the deformation zone of the end seal. Of course, the arc cannot be opened too deep, otherwise the label itself will easily cause wrinkles and increase unnecessary trouble. For special-shaped end sealing, the shape of the label is required to be changed accordingly, which can not only avoid label warping but also increase the aesthetics. (four), eliminate the influence of static electricity. The labeling process is prone to static electricity, which will have an impact on the labeling effect. Appropriately increasing the humidity of the labeling site will improve it to a certain extent. The use of ion fans is also an effective solution. The labeling machine is equipped with automatic humidity control inside, and it can also control the cleanliness of the equipment separately, keep the label away from dust, and improve the labeling quality of the product. In this way, there will be no longer the phenomenon of label warping during the labeling process, and the visual effect is achieved.
