Description

Technical Field

[0001] The utility model relates to the technical field of glue coating devices, in particular to a glue coating air knife mechanism and a film material glue coating device. Background Art

[0002] In the coating technology and packaging industry, the gluing process is one of the key steps to ensure that the product surface has a uniform protective layer. Traditional coating methods generally use anilox rollers as the core component for glue delivery, and the fine grooves on its surface can carry and evenly release the glue to the substrate to be treated. However, the stainless steel scraper that is indispensable in this process is used to control the amount of glue and achieve surface flatness, but it is accompanied by a series of technical challenges and limitations.

[0003] Specifically, the stainless steel scraper in the prior art is in direct contact with the high-speed rotating anilox roller, aiming to scrape off excess glue to maintain the uniformity of the coating layer. The defects in this design principle are mainly reflected in the following points:

[0004] 1. Blockage and imprinting problems: In continuous operation, tiny glue particles or foreign matter are easy to accumulate in the high-frequency contact area between the scraper and the anilox roller, causing blockage in the scraper gap. This blockage will not only interfere with the uniform output of glue, but also form visible line marks on the surface of the final product, seriously affecting the coating quality and appearance.

[0005] 2. Increased wear and maintenance costs: Under long-term mechanical friction, both the anilox roller and the stainless steel scraper face serious wear problems. Once the fine structure of the anilox roller surface is damaged, it will directly affect its ability to carry and distribute glue, and the wear of the scraper edge will further aggravate the unevenness of the glue layer. Frequent parts replacement not only increases production downtime, but also greatly increases maintenance and material costs.

[0006] 3. Complexity of installation and commissioning: Accurate installation and leveling of the scraper is the prerequisite for ensuring coating quality, but this process is often time-consuming and complicated. It requires a high degree of professional skills and experience to ensure the proper gap between the scraper and the anilox roller. Any slight deviation may lead to uneven coating or equipment damage, thus affecting the overall production efficiency and product quality. Utility Model Content
