Description

Technical Field

[0001] This application relates to the field of printing and coating technology, specifically to an adhesive spraying device for printing production lines. Background Technology

[0002] Printing is a technology that mass-produces original artwork, such as text, pictures, photographs, and anti-counterfeiting materials, by transferring ink to the surface of materials like paper, textiles, plastics, leather, PVC, and PC through processes like plate making, inking, and pressing. Printing involves transferring approved printing plates onto the substrate using printing machinery and specialized inks. Glue spraying equipment is used in printing lines for the glue application process.

[0003] Patent CN220759757U discloses a printing glue-applying device. This device uses a moving mechanism to move a baffle, adjusting it to the appropriate position according to the required glue width for the printing material. The baffle blocks part of the glue-dispensing tube opening, facilitating operator operation and preventing glue overflow that could contaminate the printing material and device due to excessive glue application. A dust-collecting mechanism cleans the dust surface of the printing material before glue application, preventing uneven glue application and effectively improving the glue-applying effect. Simultaneously, a drying mechanism connected to the top shell works in conjunction with the dust-collecting mechanism. While collecting dust, it heats the cold air entering the top shell to dry the glue on the printing material surface, improving drying efficiency. This solves the problems of current devices, such as the inability to adjust the glue application range and the inability to clean dust from the printing material surface, resulting in poor glue application. However, this glue-applying device relies solely on a fan to draw dust from the material surface, which is insufficient to remove strongly adhering dust, leading to poor cleaning and affecting the glue application effect, thus reducing the pass rate of printed material processing.
