Description

Technical Field

[0001] The utility model belongs to the technical field of the processing of packaging bag films for sanitary products, and particularly relates to an anti-splash ink device for film printing. Background Art

[0002] At present, in the production process of packaging bags for sanitary products, patterns and texts are printed on the surface of the film through a film printing machine. The pigment on the printing roller is conveyed through an ink cartridge. The lower end of the printing roller is located in the ink. When the printing roller rotates, the ink is smeared on its surface, and the other end of the printing roller contacts the film. The ink is printed on the film surface by the rotation of the printing roller to complete the printing of the pattern.

[0003] During the high-speed rotation of the printing roller of the printing machine, the excess ink on the surface will be thrown out, resulting in ink dots splashing. Some of the splashed ink dots will fall on the film surface, causing the ink dots to damage the picture during printing, making the printed film unusable, increasing the defective rate of the production of packaging bags for sanitary products, and being unfavorable for people's use.

[0004] Therefore, we provide an anti-splash ink device for film printing to solve the above problems. Summary of the Utility Model
