Description

Technical Field

[0001] The utility model relates to the technical field of decorative paper printing, in particular to a decorative paper gravure printing device. Background Art

[0002] In the product structure, the decorative paper mainly plays the role of providing decorative patterns and covering to prevent the bottom layer glue from seeping through. This layer requires the paper to have good hiding power, impregnation and printing properties. Decorative paper requires a smooth surface, good absorption and adaptability, uniform color for base color, and bright color for color.

[0003] Among them, the "flexible packaging film gravure printing machine" disclosed by the application number "CN211843583U" is also an increasingly mature technology, which "includes a chassis, a drying box 1 and a drying box 2 are respectively installed on the top and bottom of the chassis, and air permeable grilles are opened on both sides of the drying box 1 and the drying box 2. The inside of the chassis is rotatably provided with a feeding roller, an impression roller 1, an impression roller 2, a guide roller 1, a printing plate roller 1, a conveying roller, a printing plate roller 2, a guide roller 2 and a guide roller 3. Two ink cartridges are installed inside the chassis, and a feeding roller and a receiving roller are arranged inside the chassis. Both ends of the feeding roller and the receiving roller are provided with baffles. A driving motor is installed on one side of the chassis, and the outer walls of the feeding roller and the receiving roller are provided with a flexible packaging film. The utility model can dry the printed flexible packaging film, so that the ink printed on the flexible packaging film quickly dries, which is convenient for faster rolling of the flexible packaging film, and the two drying boxes can fully dry the front and back of the flexible packaging film, thereby improving the drying rate of the ink printed on the flexible packaging film.

[0004] However, the above-mentioned gravure printing machine design has the following disadvantages: the gravure printing machine conveys and prints the flexible packaging film through a combination of a feed roller, a first impression roller, a second impression roller, a first guide roller, a first printing plate roller, a transfer roller, a second printing plate roller, and a second guide roller. This structural design is relatively simple and cannot level the decorative paper during printing, resulting in deviations in the printed pattern of the decorative paper. At the same time, the printed decorative paper pattern cannot be dried, resulting in poor saturation of the pattern on the surface of the decorative paper.

[0005] Therefore, it is necessary to provide a decorative paper gravure printing device to solve the above problems. Utility Model Content

[0033] A concave plate seat 106 is provided on the top of the transport frame 3 .

[0034] During specific use, when gravure printing of decorative paper is performed, the decorative paper is discharged through the discharge roller 102, and then the decorative paper is kept flat through the leveling mechanism 2 to avoid wrinkles, and then the decorative paper is transported by the transmission frame 3 through the printing mechanism 4 to be printed on the concave plate seat 106, and the surface of the decorative paper is dried by the set high-temperature hydraulic mechanism 5 to improve the saturation effect of the printed pattern.

[0035] The leveling mechanism 2 includes a first electric telescopic rod 201 fixedly connected to the top of the printing fixed frame 1, the telescopic end of the first electric telescopic rod 201 is fixedly connected to the leveling frame 202, one end side of the leveling frame 202 is fixedly connected to the first driving motor 203, the driving end of the first driving motor 203 is fixedly connected to the first active turntable 204, the outer side of the first active turntable 204 is transmission-connected with a belt 205, one end of the belt 205 is transmission-connected to the first driven turntable 206, the outer side of the belt 205 is fixedly connected to the first movable slide 208, the back side of the first movable slide 208 is slidingly connected to the first slide rail on the printing fixed frame 1, the top of the first movable slide 208 is fixedly connected to the second electric telescopic rod 209, the telescopic end of the second electric telescopic rod 209 is fixedly connected to the leveling fixed frame 2010, and the bottom end of the leveling fixed frame 2010 is fixedly connected to the leveling plate 2011.

[0036] During specific use, the decorative paper to be printed is leveled to avoid wrinkles in the decorative paper during the printing process, so that the pattern cannot be printed on the decorative paper with high quality. The extension and retraction of the first electric telescopic rod 201 facilitates the driving of the leveling mechanism 2 to approach the decorative paper, and the rotation of the first driving motor 203 drives the first active turntable 204 to rotate. The rotation of the first active turntable 204 facilitates the driving of the belt 205 to drive the first driven turntable 206 to rotate, so that the first movable slide 208 slides left and right along the first slide rail, thereby ensuring that the leveling plate 2011 levels the decorative paper.
