Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a high-quality printing mechanism on the surface of wallpaper. Background Art

[0002] The wallpaper is transported on the conveyor belt. The surface of the printing roller is concave and convex, and the raised parts are dipped in ink. The rotating printing roller applies the ink to the wallpaper being transported. Different rollers apply different patterns and colors on the wallpaper. After printing is completed, the wallpaper will be pulled to the drying area, and the ink printed on its surface will be dried by the drying device.

[0003] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and were not well solved: the ink on the roller would be thrown to the non-printing area as it rolled, such as a rubber conveyor belt, and the edge of the wallpaper would come into contact with the excess residual ink, resulting in mis-dyeing, which seriously affected the printing quality.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a high-quality wallpaper surface printing mechanism comprises a conveying device 1, on which a plurality of printing rollers 2 are arranged, and L-shaped plates 3 are arranged at both the front and rear ends of the conveying device 1 between two adjacent printing rollers 2, and the L-shaped plates 3 are threadedly connected with adjusting screws 4, and the adjusting screws 4 pass through the L-shaped plates 3 and are rotatably connected with a box cover 5 at the bottom position located at one end of the top of the conveying device 1, and a box body 6 is arranged below the box cover 5, and an inner cotton body 8 is embedded in the box body 6, and a box groove 61 is cut in the inner bottom of the box body 6, and the bottom of the inner cotton body 8 located at the box groove 61 is provided with An air pipe 11 is fixedly passed through the outer cotton body 9 and the L-shaped plate 3, one end of the air pipe 11 passing through the L-shaped plate 3 is connected to a hose 12, one end of the hose 12 away from the air pipe 11 is threadedly connected to a suction nozzle 13, and a memory metal rod 16 is fixed on the side wall of the L-shaped plate 3 located above the hose 12, one end of the memory metal rod 16 away from the L-shaped plate 3 is fixedly connected to the suction nozzle 13, and the memory metal rod 16 can be bent at any angle through its own characteristics, and achieve the effect of limiting the suction nozzle 13, so that the suction nozzle 13 can surround and absorb residual ink at an angle as needed.

[0023] Specifically, the outer cotton body 9 is connected with the box groove 61 respectively, and a bevel groove 10 is cut on one side of the bottom of one end of the outer cotton body 9 passing through the box groove 61, and the bevel can guide the residual ink to the suction nozzle 13.

[0024] Specifically, the suction nozzles 13 are respectively located at one side of the inclined groove 10, and can absorb the excess ink that cannot be absorbed in time or the residual ink in the saturated state.

[0025] Specifically, the bottom of the outer cotton body 9 is in contact with the edge surface of the conveyor belt on the conveyor device 1, so as to absorb the residual ink thrown onto the edge surface of the conveyor device 1, thereby preventing the residual ink from seeping into the edge of the wallpaper.

[0026] Specifically, a slide bar 7 is fixed to one end of the top of the box cover 5 away from the adjusting screw 4. The ends of the slide bar 7 away from the box cover 5 are respectively penetrated through the L-shaped plate 3 and then slidably connected, so that the box cover 5 and the box body 6 can be lifted and lowered horizontally.

[0027] Specifically, the bottom outer wall of the box cover 5 is provided with a card block 14, and the inner top of the box body 6 is opened with a card groove 15. The box cover 5 is respectively engaged with the card groove 15 on the box body 6 through the card block 14, so that the inner cotton body 8 and the outer cotton body 9 can be easily taken out from the box body 6 for replacement.

[0028] Working principle:

[0029] After the ink on the printing roller 2 is thrown to the edge of the wallpaper on the conveying device 1, as the conveying device 1 moves, it will contact the bottom of the outer cotton body 9, and the residual ink will be adsorbed by the outer cotton body 9 to avoid the residual ink being retained on the conveying device 1 and causing the problem of contaminating the edge of the wallpaper, thereby improving the quality of printing. When there is too much residual ink on the edge, the suction device can absorb the residual ink blocked by the outer cotton body 9 at the position of the inclined groove 10 through the connected air pipe 11, hose 12, and suction nozzle 13 to avoid the hidden danger that the residual ink is retained at this position and the inclined groove 10 can no longer be adsorbed after the adsorption is saturated. The suction device for ink absorption is a technical means for adsorbing ink with a tube, and its specific structure will not be described too much in this application. After the adjusting screw 4 rotates, it can drive the box cover 5 to rise until the bottom of the outer cotton body 9 is away from the top surface of the conveying device 1, and then the inner cotton body 8 and the outer cotton body 9 can be taken out from the box body 6 and replaced by the snap connection between the box cover 5 and the box body 6, so that it has a better adsorption effect later.

[0030] The conveying device 1 and the printing roller 2 are respectively driven by driving devices to rotate, and the printing roller 2 is provided with a device to apply ink on its surface. These are existing, public and very mature prior arts, and will not be described in detail in this application.

[0031] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.
