[0002] Packaging bags refer to bags used to package various supplies, making it convenient to transport and store goods during the production and circulation process. Packaging bags are one of the most common products in life. Packaging bag printing machines are used to print patterns such as product logos and text such as production information on packaging bag films.

[0003] The packaging bag gravure printing machine is a machine that uses gravure printing. The ink tray of the packaging bag gravure printing machine is soaked with an ink transfer roller, which transfers the ink to the inking roller that is in close contact with it. The roller surface of the inking roller is provided with a concave pattern corresponding to the required printing. The graphic part of the printing plate is concave, and the blank part is on the same plane as the outer circle of the ink transfer roller. The ink is smeared on the concave pattern, and the ink on the pattern is smeared on the surface of the packaging bag film through the pressure between the inking roller and the guide roller that transfers the packaging bag film, thereby achieving the effect of printing on the packaging bag film.

[0004] As the ink tray is used for a long time, ink accumulates at the bottom of the tray, the viscosity of the ink increases, and the ink condenses into lumps and sticks to the tray. These lumps of ink cannot be used, which affects the capacity of the tray. To solve this problem, it is necessary to propose a new technical solution for cleaning the ink tray. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a packaging bag gravure printing device and an ink tray thereof to solve the above problems.

[0026] Specifically, the top of the base 3 is provided with an inward-concave snap groove 320, and the bottom of the side blocking surface 13 of the disk body 1 is provided with a snap protrusion 131 that fits with the snap groove 320, forming a stable snap connection structure between the disk body 1 and the base 3, and the structure is simple and easy to implement.

[0027] In order to facilitate the operator to pull out the base 3, a pulling handle 33 is fixed on the side of the base 3.

[0028] It is necessary to make the ink naturally concentrate toward the ink receiving cavity 30 of the base 3 under the action of gravity, so that when the ink liquid level is high, it will not affect the inking of the ink transfer roller 2. Specifically, the front slope 11 and the rear slope 12 of the plate body 1 are symmetrically arranged to form a funnel-like shape, and the scraper plate 31 constitutes a corresponding concave oblique edge, which is trapezoidal in shape.
