working principle of hot melt adhesive labeling machine:
The rotary hot-melt adhesive labeling machine automatically controls the operation of the labeling machine (low, medium, high, and stop) through the detection point set on the conveying chain in the bottle feeding direction, and transfers the bottle to the rotary mechanism by screw. The labeling machine starts automatic operation after receiving the bottle-feed signal fed back by the detection device. After the label passes the tensioning mechanism and the deflector, it enters the label cutting mechanism and cuts the label to a specified length. The cut label is transferred to the labeling mechanism through vacuum adsorption, and the rotating labeling mechanism is turned over the rolling mechanism, and the hot-melt adhesive labels are affixed to both ends of the label. After the bottle is flattened with a labeler through a labeling device, the labeling process is completed. At the same time, the speed of the equipment can be controlled (stopped or operated) through the detection point set by the bottle chain.
1. Use hot-melt adhesive to attach a ring-shaped label;
2. Use hot melt adhesive to stick part labels;
3. Hot melt adhesive labeling machine can be used for positioning and labeling of special-shaped bottles such as square bottles;
4. Can be used for labeling before or after filling;
5. Rotary hot melt adhesive labeling machine can be applied to paper, PET, OPP, BOPP, etc
6. Can be used for PET, glass, metal and other bottle labeling.
1. Through the optimized design of the structure, the number of wearing parts is minimized and the service life is increased.
2. The configuration of different bottle types and labels can be replaced within 10 minutes.
3. The adjustment process of the movable and fixed cutter is simple, the cutting performance number is long, and the service life is high.
4. Rotary hot melt adhesive labeling machine has strong adaptability to labels through optimized design of label conveying mechanism and control system.
5. By optimizing the design of the rubber supply system and the rolling mechanism, the adaptability to hot melt adhesive is very strong.
