(1) The upper and lower conveyor belts hold the cardboard forward. The main function of the automatic box gluing unit is to fold and bond the cardboard that has undergone processes such as printing, slotting, and die-cutting, forming finished cartons. Among them, the holding of cardboard by the upper and lower conveyor belts is one of the important working steps of the automatic box gluing unit. Through the clamping action of the upper and lower conveyor belts, the cardboard can be stably held and conveyed to the next processing stage, ensuring the continuity and stability of the entire production process. This clamping method can effectively prevent the cardboard from shifting or sliding during the conveying process, ensuring that each piece of cardboard can accurately enter the next process, thereby improving packaging efficiency and production quality.

(2) Side pressure line device and vacuum adsorption belt conveying system. The side pressure line device and vacuum adsorption belt conveying system of the automatic gluing unit are key components to ensure that the cardboard remains stable and precise during the folding and bonding process. The side pressure line device is located at the front section of the folding part, adjusting the lateral pressure on the folded cardboard through side pressure wheels installed at the folding knife opening. This design effectively eliminates any potential displacement or deformation of the cardboard during the folding process, ensuring that the folding lines of the boxes are neat and precise, thus improving the quality and aesthetic appearance of the packaging. Meanwhile, the vacuum adsorption belt conveying system is located at the rear section of the folding part, providing stable transportation of the cardboard through the vacuum adsorption belt, preventing slipping or sliding during the conveying process, and maintaining the stability and cleanliness of the cardboard.

(3) Advanced spray glue system and precise counting stacking output function. The advanced spray glue system and precise counting stacking output function of the automatic carton gluing unit are key components to ensure even glue application, strong adhesion, and orderly stacking of the final product during the carton packaging process. The advanced spray glue system uses original VALCO technology imported from the United States, featuring a non-contact accurate spray glue function that automatically tracks the spray glue position without manual settings, ensuring even and precise glue application on each piece of cardboard during the bonding process. This design effectively reduces glue waste and the problem of excessive application, improving the efficiency and cost-effectiveness of the packaging production line. At the same time, the precise counting stacking output function ensures that the packaged carton products are stacked neatly and orderly during the output process, avoiding unstable stacking or misalignment of cartons during output, thereby enhancing the overall appearance quality and stacking stability of the packaged products.
