Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical printing devices, in particular to a cylindrical printing nickel screen anti-fracture reinforcement device. Background Art

[0002] Rotary screen printing is a printing method that uses a scraper to print the color paste in the rotary screen onto the fabric under pressure. Rotary screen printing differs from other screen printing methods in several important aspects. Rotary screen printing is a continuous process, just like roller printing. The printed fabric is transported to the bottom of the constantly moving rotary screen flower cylinder by a wide rubber belt. Among the screen printing methods, rotary screen printing has the fastest production speed, exceeding 3,500 yards per hour, and uses seamless perforated metal or plastic mesh. The largest rotary screen circumference is greater than 40 inches, so the largest flower size is also greater than 40 inches. Rotary screen printing machines with more than 20 sets of colors have also been produced. This printing method is slowly replacing roller printing. The existing cylindrical printing nickel screen needs to exert greater pressure on the printed fabric when in use to print the dye on the fabric. Due to the thin thickness of the nickel screen, the printed part is easily deformed when under stress, which may cause breakage during use. Utility Model Content
