[0002] At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has shifted from the backward situation of manual and semi-automatic labeling to the pattern of automated high-speed labeling machines occupying a large market. Labeling machines are equipment that sticks rolled self-adhesive paper labels (paper or metal foil) on products or specified packaging. Labeling machines are an indispensable part of modern packaging. Patent application number: CN202022351010.3 discloses a precisely positioned star wheel round bottle labeling machine, including a fixed box, a reduction motor, a rotating shaft, a driving wheel, a fixed frame, a driven wheel and a pressing belt. The top of the machine is fixedly connected with a star wheel rotating mechanism, and the star wheel rotating mechanism is arranged relative to the positioning labeling mechanism. When in use, the round bottle is manually placed in the conveying trough at the top of the conveyor. The bottles will be stuck in the star wheel rotating mechanism one by one after being conveyed by the conveyor. The pressing belt is in close contact with the surface of the round bottle. When the star wheel rotating mechanism and the positioning labeling mechanism interact with each other to convey the round bottle, the round bottle will rotate, and the pressing belt can press the label on the surface of the round bottle. However, this type of round bottle labeling machine fixes the star wheel rotating mechanism on the machine table, and the gap between the pressure belt and the star wheel rotating mechanism cannot be adjusted, resulting in this type of round bottle labeling machine being able to only meet the labeling needs of round bottles of one size.
