Usually, consumers believe that natural and exquisite wine labels will make people feel that wine products are of good quality and competitive. On the contrary, the appearance of rough paper labels and uneven labeling of wine products will make people feel low quality.
Traditional wine label papers are usually cloth paper or coated paper, and the labeling method is glued with cold glue. Since the cold glue is adjusted during processing to a process parameter such as viscosity and fluidity, a relatively high proportion of water is added. However, whether it is a textured paper or a coated paper, it is a very absorbent material. After the label is applied, the standard paper will absorb the moisture in the glue and be easily wrinkled. At the same time, the cold glue labeling machine is determined by the working principle in the labeling process, and it has to go through intermediate transitions such as glue coating, glue labeling and labeling. In this way, in the process, some small grooves are to be opened on the back side of the rubberized board, and the standard paper is not glued at the notch, and the unevenness of the paper due to uneven water absorption may cause wrinkles. If the label is too thick or the viscosity of the glue is not good, the label paper is not firmly attached to the bottle, and there is also a curling phenomenon. Most companies now use manual wrapping to deal with this problem, but this method is time consuming and inefficient.
In order to solve this problem, some wine companies have introduced the grades of their own wine products and introduced self-adhesive labels. Its appearance is exquisite, the labeling is neat and generous, and the products after posting are outstanding. Most of the foreign wine products used self-adhesive labeling as early as 10 years ago. However, if the sticker is manually labeled, it is difficult for the operator to stick it up. If it is not correct, the sticker is very sticky. The standard paper is difficult to clean and the production efficiency is not improved.
In this case, the labeling machine for the wine industry was born. The principle of this labeling machine is that the label paper is directly peeled off from the label and attached to the bottle during the labeling process, which eliminates the intermediate link of the cold glue labeling machine to transfer the label paper during labeling. The gauge length error is reduced and the accuracy is greatly improved.
In order to meet the needs of wine manufacturers with different production and different labeling requirements, a new self-adhesive labeling machine was born for the characteristics of the wine industry. The following two types of models are linear self-adhesive stickers and rotary self-adhesive labeling machines.
The linear self-adhesive labeling machine generally has a labeling speed of 1500-2000 bottles/small source of Chinese wine information network, which can satisfy some wine users with smaller output. This type of machine does not need to replace parts when replacing the bottle type in the production process. As long as the standard paper is replaced, the labeling parameters can be adjusted and modified to be put into production, and the operation is simple.
The rotary self-adhesive labeling machine is suitable for a wide range of bottle types, and the labeling speed of different models can meet 3000-15000 bottles/hour. Bottles of various shapes (round bottles, square bottles, flat bottles, conical bottles, etc.) can be attached by replacing the guide bottle tool.
The self-adhesive labeling machines of these two models mainly have the following technical features:
The sticker station part is the core part of the sticker labeling machine. The part of our company's standard station is that we cooperate with Italian companies and design and produce them in Italian technology. The paper-pulling transmission is more accurate and stable, the paper-disc drive is stable, and the structure of the delivery unit is novel and practical.
The driving of the standard station adopts stepping drive, and the standard is stable and the accuracy is high.
The control part uses Mitsubishi PLC combined with touch screen parameter modification to control the stepping drive. All label correction parameters can be modified on the touch screen without mechanical adjustment. Easy to use. For the wine labeling method, the body back label is adopted and the production speed is frequently adjusted. In the gauge length adjustment control, the time control of the general manufacturer is not used, but the encoder count control is adopted. The gauge length does not change as the time control changes when the device's operating speed changes. The labeling accuracy is very high and the gauge length adjustment can be adjusted within 0.5mm. Labeling accuracy and symmetry are among the best in the industry.
The rotary self-adhesive labeling machine can also realize the positioning labeling by adding some accessories. The labeling product on the bottle can also realize automatic labeling, and the positioning accuracy is high.
The introduction of self-adhesive label paper in the wine industry and the advent of self-adhesive labeling machines have solved the problem of traditional cold-adhesive label paper labeling and curling. While the majority of wine users in China continue to improve the intrinsic quality of their wine products, the aesthetics of the wine packaging also increases. With the improvement of people's living standards and the appreciation of wine, self-adhesive labeling will be promoted and popular, and will add a beautiful landscape to the future wine industry.
