[0002] As a common packaging material, paper-plastic bags are widely used in the production lines of food, chemical industry, pharmaceutical industry and other industries.

[0004] At present, the labeling operation in this field mainly relies on semi-automatic equipment or manual operation. Although the traditional semi-automatic equipment can reduce the labor intensity to a certain extent, the inherent technology leads to the fact that the labeling position accuracy cannot be stably controlled. Due to the lack of high-precision positioning and compensation system, the equipment cannot sense the actual position deviation of the bag body, and cannot perform real-time dynamic adjustment, so that when deviation occurs, it will affect the product quality. At the same time, the quality detection link relies on manual operation. After labeling, the operator needs to visually recheck to determine whether the label content is correct, the position is accurate, and the surface is free of pollution or wrinkles. Batch abnormal problems cannot be found in time. And lack of intelligent sorting and data feedback mechanism, after finding defective products, manual sorting and removal are still needed, real-time linkage with the production line cannot be formed, and at the same time, the data in the production process cannot be effectively recorded and analyzed, the present application provides an intelligent paper-plastic bag automatic matching and labeling equipment.
