Description

Technical Field

[0001] The utility model relates to the field of positioning devices, in particular to a positioning device for labeling wine bottle caps. Background Art

[0002] Wine bottle caps are components used to fasten wine bottles and seal them, and are usually made of plastic or aluminum. Depending on the different functions and materials of the bottle caps, the designs and structures of the bottle caps are also different. Some bottle caps require specific opening methods, while some bottle caps are designed to be reused multiple times. Therefore, wine bottle caps play a vital role in the preservation quality and safety of wine. Usually, labels are affixed to wine bottle caps for easy identification and sale. Most of the existing wine bottle caps are labeled manually or semi-automatically. Due to the uncontrollability of the labeling process, the labeling position is easy to deviate, resulting in mismatch between the label and the wine bottle cap, which reduces work efficiency and affects subsequent sales. Therefore, we propose a positioning device for labeling wine bottle caps to solve the above-mentioned problems. Utility Model Content
