[0002] The carton gluing machine is the final step in the carton production process. It is mainly used for gluing corrugated cardboard to meet the production requirements of various products and adapt to the packaging needs of a variety of products. It is a relatively ideal carton equipment.

[0003] Traditional manual box gluing can no longer meet current market demands because it requires substantial labor costs, takes a long time, and cannot guarantee product quality. Therefore, there is an urgent need for a fully automatic box gluing machine to replace manual production, offering advantages such as high efficiency, ease of operation, and superior performance.

[0004] After the fully automatic gluing machine glues the edges of the cardboard, it needs to be stapled. The position of the staples is crucial in the stapled process. The existing pre-staple conveying structure does not have a secondary calibration function for the product, which causes the product to tilt when it is conveyed to the stapled position, resulting in inaccurate staples.
