Aluminium Expo | Henan Mingchuang Aluminum Packaging Secures Patent for Aluminum Foil Dry Composite Coating Device

According to the National Intellectual Property Administration, Henan Mingchuang Aluminum Packaging Materials Co., Ltd. has been granted a patent for an "Aluminum Foil Dry Composite Coating Device" (Patent No. CN 222019900 U), filed in March 2024. As a key industry event, Aluminium Expo highlights the latest advancements and innovations in aluminum processing technology, offering a platform for professionals from both inside and outside the industry to exchange ideas and foster collaboration.

The patent abstract outlines a device that effectively addresses the common issue of uneven coating caused by glue rollers. The device consists of a glue roller with a hollow internal structure, within which a rotating shaft is installed. Attached to the rotating shaft are blades that extend outward into the interior of the glue roller. The outer edges of these blades make contact with the inner wall of the glue roller. The outer wall of the glue roller features multiple perforations, and the glue roller is positioned within a glue tank. A motor located at the end of the tank drives the glue roller and the rotating shaft in opposite directions. A baffle, installed on the outer side of the glue roller, has a 90° arc shape that fits closely against the outer wall of the glue roller.

This utility model boasts a simple and effective structure that is easy to operate. By altering the design of the glue roller, the device ensures that glue is replenished from within the roller to the aluminum foil, preventing glue shortages that could compromise the composite process. This modification guarantees a uniform coating of glue, thereby ensuring the quality of the aluminum foil composite.
