DETAILED DESCRIPTION

[0030] Please refer to Figures 1-3 The printing machine for the self-adhesive label in the embodiment comprises a printing box 1, the inside of the printing box 1 is provided with a printing roller assembly 2, and the inside of the printing box 1 is provided with a cleaning mechanism.

[0031] It should be noted that the printing roller assembly 2 comprises a platen roller, a rubber roller, a plate cylinder, a roller and an ink roller. In printing, first, the water roller supplies the dampening liquid to the plate to make the blank part absorb water to form a water film that resists ink infiltration. Then, the ink roller supplies the ink to the plate to make the graphic part adhere to the ink. Then, the ink of the graphic part is transferred to the surface of the printing material through the rubber roller to complete the printing process. The specific principle of the printing roller assembly of the lithographic printing technology is known technology.

[0032] The cleaning mechanism comprises an isolation cover 3, a cleaning roller 5, an adjusting plate 13, a limiting plate 18 and two side plates 12. The cleaning roller 5 is rotationally connected between the two side plates 12. The adjusting plate 13 and the limiting plate 18 are fixedly connected to the inner top wall of the isolation cover 3. One side plate 12 is slidingly connected to the limiting plate 18. The side plate 12 away from the limiting plate 18 is provided with a threaded column 15. The outer thread of the threaded column 15 is connected to a nut abutting against the side wall of the adjusting plate 13. The length of the adjusting hole 14 is greater than the diameter of the threaded column 15. One end of the threaded column 15 extends to the outside through the adjusting hole 14 in the inside of the adjusting plate 13. One side of the cleaning roller 5 is fixedly connected with a fixed pipe 17. The side wall of the printing box 1 is provided with a dust suction assembly.

[0033] It should be noted that the cleaning roller 5 can be adjusted in height by rotating and loosening the nut. Then, the cleaning roller 5 can be located at the adjusted position by tightening the nut, so that the gap between the cleaning roller 5 and the supporting roller 4 can be conveniently adjusted.

[0034] In the embodiment, the inner bottom wall of the isolation cover 3 is provided with the supporting roller 4. The side wall of the isolation cover 3 is provided with an outlet. The isolation cover 3 has a “U” structure.

[0035] The self-adhesive label cleaned of dust is moved out of the outlet and then printed by the printing roller assembly 2 through the outlet.

[0036] Please refer to Figure 1In the present example, the dust collection assembly includes an upper cylinder 7 and a lower cylinder 11. The upper cylinder 7 is arranged on the side wall of the printing box 1, and the lower cylinder 11 is threadedly connected to the lower side of the upper cylinder 7. The side wall of the upper cylinder 7 is fixedly connected with a suction pipe 6, and the end of the suction pipe 6 away from the upper cylinder 7 is rotatably connected to the inside of a fixed pipe 17. A filter cylinder 10 is clamped between the inner walls of the upper cylinder 7 and the lower cylinder 11. A section of the suction pipe 6 is a flexible hose, and the two sides of the flexible hose are hard pipes. The top of the upper cylinder 7 is provided with a suction fan 8, and the suction fan 8 is connected with the upper cylinder 7 through a connecting pipe 9. The dust on the surface of the adhesive can be sucked into the lower cylinder 11 and collected by the suction fan 8.

[0037] The dust on the surface of the adhesive is sucked into the lower cylinder 11 by the dust collection assembly, and the bottom of the lower cylinder 11 is provided with a rotating handle. The dust inside the lower cylinder 11 can be easily removed by rotating the rotating handle.

[0038] When the adhesive is conveyed, it first enters the isolation cover 3 and passes between the cleaning roller 5 and the supporting roller 4. The adhesive label drives the cleaning roller 5 to rotate during the conveying process. The cleaning roller 5 can clean the dust and impurities on the surface of the adhesive, and the dust and impurities cleaned can be sucked into the upper cylinder 7 and the lower cylinder 11 by the dust collection assembly. Thus, the dust and impurities on the surface of the adhesive label before printing can be cleaned in time to avoid affecting the printing effect.

[0039] The hard pipe connected with the cleaning roller 5 can displace along with the cleaning roller 5 when the height of the cleaning roller 5 is adjusted.

[0040] Please refer to Figure 3 The outside of the suction pipe 6 is fixedly provided with a limiting block 16, and the limiting block 16 is slidably connected to the side wall of the printing box 1.

[0041] The limiting block 16 can slide up and down on the side wall of the printing box 1 to limit the suction pipe 6, so that the suction pipe 6 cannot rotate with the cleaning roller 5.

[0042] Please refer to Figure 4 The cleaning roller 5 is a hollow cylinder, and the cleaning roller 5 is provided with a cleaning brush sleeve 51 outside. A plurality of air inlet holes 52 are formed in the cleaning roller 5 and the cleaning brush sleeve 51.

[0043] The air inlet holes 52 are flexible pads, which can contact the surface of the adhesive to clean the dust on the surface.

[0044] The working principle of the above embodiment is that the device cooperates with the winding and unwinding equipment to transport the self-adhesive labels to be printed. The self-adhesive labels enter the inside of the printing box 1 from the feed port in the side wall of the printing box 1. The self-adhesive labels in the printing box 1 pass between the cleaning roller 5 and the supporting roller 4 first. Under the action of friction, the cleaning roller 5 and the supporting roller 4 rotate. The rotation of the cleaning roller 5 on the surface of the self-adhesive label can clean the dust and impurities on the surface. At the same time, after the suction fan 8 is electrified, under the action of suction, the dust and impurities can be sucked into the inside of the cleaning roller 5 from the air inlet hole 52, and then be sucked into the inside of the upper cylinder 7 and the lower cylinder 11 through the air extraction pipe 6. The dust is intercepted in the filtered gas through the filter cylinder 10, so that the dust is left in the inside of the lower cylinder 11. The filtered dust is discharged to the outside, so that the dust and impurities on the surface of the self-adhesive label before printing can be cleaned in time to avoid affecting the printing effect.
