Description

Technical Field

[0001] The utility model belongs to the technical field of labeling machines, and in particular relates to a high-precision automatic labeling machine. Background Art

[0002] Automatic labeling machine is a device that can stick rolled paper or metal foil labels on specified packaging containers or objects. The labels have adhesive on the back and are regularly arranged on the glossy backing paper. The label peeling mechanism on the labeling machine can automatically peel them off. Labeling can complete various operations such as flat labeling, single-sided or multi-sided labeling of packaging, cylindrical labeling, partial or full coverage of cylindrical labeling, and labeling of concave and corner parts.

[0003] The existing automatic labeling machine uses a conveyor belt to transport and label objects. The width of the object is often smaller than the distance between the two sets of vertical plates of the conveyor belt, which causes the movement trajectory of the object to shift during transmission, making it easy to stick the label on an angle during labeling, which affects the appearance and reduces the labeling accuracy. In addition, during the labeling process, the object is prone to warping, loose labeling, and hollowing in the middle of the label. Therefore, we propose a high-precision automatic labeling machine to solve this problem. Utility Model Content

[0042] Specific working principle: The utility model provides a high-precision automatic labeling machine. When in use, the staff needs to place the object on the surface of the conveyor belt 214. After placing it, the conveying motor 211 is started. The conveying motor 211 drives the conveyor belt 214 to rotate, and then the object is conveyed. During the conveying process, the electric push rod 220 is started, and the electric push rod 220 drives the guide plate 222 to move inward, and the guide plate 222 cooperates with the guide wheel 223 to limit the object so that the object does not deviate during movement.
