Small labeling machine is a relatively common labeling equipment. It is inseparable from both daily and work. For example, we can see that the labels on bottles and cans are used in supermarkets and shopping malls. The effect of the invention of the small labeling machine not only makes the product beautiful, but also makes us understand the product. Of course, what we see more often in the day is the objects of round bottles and cans. How does the shirt labeling machine use the posting method to stop the labeling work? In fact, it is very simple. The small labeling machine applies labels to round bottles and other containers. Its movement methods can be roughly divided into two categories. The first category is wine bottles and beer bottles. The bottle was moved forward while standing, and the label of the pre-coated adhesive was attached to the bottle. There are three situations here: 1. The wine bottle moves forward intermittently, and the label is posted when it moves intermittently. 2. The label is sent out during the movement of the wine bottle to stop posting. 3. The line is cut off 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 bigger problem in the movement of small labeling machines is the problem of posting. Generally, labels coated with liquid adhesive are used. Due to the emergence of new types of labels such as pressure-sensitive, heat-sensitive, and hot-melt labels, the installation of various small labeling machines has been carried out again. The problems of using liquid adhesives are: initial viscosity, quick-drying function, maintaining the good condition of the paint roller, avoiding the adhesive from sticking to the guide roller, and the limitation of the raw materials of the surface. Especially in places where high-speed machinery is used, there are certain restrictions on the selection of adhesive solvents and the drying time of the solvents. The heat-sensitive label has its advantages. It is heated to agglomerate the adhesive. After the heat is reduced, the adhesive can be maintained for a long time, so that the heating and pressing operations of the small labeling machine can be separated and stopped. Seed material guess stop posting. The advantage of the hot-melt type is that it condenses only when it is heated, and it adheres immediately after cooling, and the materials that can be posted can be used throughout. However, it should be noted that this method is different from the adhesive that penetrates into the material and condenses. Due to the different types of materials posted, there is a risk of falling off due to the drying of the label after a long period of time.
