What kind of equipment does Anshan labeling machine belong to-industry news

The labeling machine is a relatively common labeling equipment. It is inseparable from both in life and work. For example, we can see that the labels on bottles and cans in supermarkets and shopping malls use stickers. The effect created by the marking machine not only makes the product beautiful, but also allows us to understand the product. The category is wine bottles and beer bottles. The bottle moves forward while standing, and the label with the pre-coated adhesive is attached to the bottle. Here can be divided into three situations: 1. The wine bottle moves forward intermittently, and the label is attached when it stops moving, 2. The label is sent out for pasting during the movement of the wine bottle, 3. The line is cut synchronously with the moving speed of the bottle attach a label. The second category is small medicine bottles. The bottle lies horizontally and rotates for labeling. The big problem in the movement of the labeling machine is the sticking problem, which is generally the use of labels coated with liquid adhesive. Due to the emergence of new types of labels such as pressure-sensitive, heat-sensitive, and hot-melt labels, various labeling machine devices have undergone new developments. The problems of using liquid adhesives are: initial viscosity, quick-drying performance, maintaining the good condition of the paint roller, preventing the adhesive from sticking to the guide roller, and the limitation of the adhesive surface material. Especially when high-speed machinery is used, the choice of adhesive solvent and the drying time of the solvent are also limited. The heat-sensitive label has its advantages. It melts the adhesive by heating, and can maintain the stickiness for a long time after the heat is reduced, so that the heating and pressing operations of the labeling machine can be carried out separately. The material is pasted. The advantage of the hot-melt type is that it only melts when heated, and adheres immediately after cooling. There are a wide range of materials that can be pasted. However, it should be noted that this method is different from the adhesive that penetrates into the material and solidifies. Due to the difference in the type of material to be pasted, there is a danger of the label falling off after a long period of time due to drying.
