Description

[0002] In the packaging industry, product labels play a crucial role, not only bearing brand information, product descriptions and other core elements, but also directly affecting the appearance quality and market competitiveness of products. Traditional manual labeling methods have been difficult to meet the needs of modern large-scale and high-efficiency production due to low efficiency, inaccurate labeling position, and problems such as label wrinkling or falling off. With the progress of science and technology and the widespread application of industrial automation technology, simple labeling machines have gradually replaced manual labeling.

A rolling mechanism 7 applies pressure to the labels, ensuring they adhere tightly and securely. An unqualified label detection system 200 detects bottles with unqualified or missing labels. Upon detection, a rejection mechanism 8 immediately activates to reject these bottles. Bottles with acceptable labels are then transported back by conveyor belt 2 and pushed to the next process step by a bottle pusher 9. To accommodate bottles of different sizes, the width of the mesh belt feeding device 10's outlet can be adjusted using the feeder adjustment device 400.
