Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing presses, in particular to a wiping device for high-gloss gravure ink. Background Art

[0002] A gravure printing press is a machine that uses a gravure plate for printing. The image and text part of the printing plate is concave, while the blank part is on the same plane as the outer circle of the plate cylinder. When the gravure printing press is printing, the entire surface of the plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a scraper, leaving the ink on the image and text part. The paper is then passed, and the impression cylinder is used to imprint on the back of the paper, so that the ink in the concave part is directly transferred to the paper surface. Finally, the printed matter is stacked or rewound through the paper collection part.

[0003] Due to the different compositions of different gravure inks, the viscosity of the inks is also different. The viscosity of high-gloss gravure inks is higher. When scraping the ink, some ink will still remain on the roller, affecting the quality of the printed product.

[0004] Therefore, a wiping device for high-gloss gravure ink is provided to scrape off excess ink on the printing cylinder before printing to ensure the quality of printing. Utility Model Content

[0026] Specifically, the vertical plates 1 are a pair, and the inner sides of the two vertical plates 1 are connected with a carrier plate 2, which is fixed between the vertical plates 1 so that the vertical plates 1 support the carrier plate 2; an ink tray 3 is provided at the bottom of the carrier plate 2, and a printing roller 6 is provided above the ink tray 3, and the ink is placed on the ink tray 3, and the bottom of the printing roller 6 is placed inside the ink to ink the printing roller 6; rotating rods 5 are provided on both sides of the printing roller 6, and a wiping block 52 is provided at one end of the rotating rod 5 facing the printing roller 6, and the excess ink on the printing roller 6 after inking is scraped off by the wiping block 52; a control box 11 is provided on the outer side of the vertical plate 1 on one side, and a plurality of support seats 12 are evenly provided on the bottom surface of the control box 11, and the support seats 12 provide stable support for the control box 11.

[0027] The control box 11 has an opening on one side perpendicular to the vertical plate 1 . A control device 13 is disposed inside the control box 11 , and one end of the control device 13 is flush with the end surface of the control box 11 .

[0028] Specifically, the control device 13 is placed inside the control box 11, so that the control device 13 can adjust and control the entire system.

[0029] Both ends of the ink tray 3 are connected to the inner sides of the two vertical plates 1 , and slide rails 21 are vertically arranged on both sides of the ink tray 3 . A pair of slide rails 21 are symmetrically arranged on each side of the ink tray 3 , and one end of the slide rail 21 is flush with the end surface of the carrier plate 2 .

[0030] Specifically, the slide rail 21 is disposed on the top surface of the carrier plate 2 ; a slide rail 21 is vertically disposed on each of the four top corners of the ink tray 3 , so that the slide rails 21 on the same side are parallel to each other.

[0031] The slide rail 21 is electrically connected to the control device 13 . A slider 4 is provided inside the slide rail 21 . A pair of hydraulic rods 41 are provided on the top of the slider 4 . A deflection block 42 is provided on the top of the hydraulic rod 41 . A connecting rod 51 is provided on the opposite side of the two deflection blocks 42 .

[0032] Specifically, the control device 13 controls the slider 4 to move inside the slide rail 21, and controls the hydraulic rod 41 to rise and fall; when the hydraulic rod 41 is controlled, the hydraulic rod 41 on the slider 4 close to the printing roller 6 moves synchronously, and the hydraulic rod 41 on the slider 4 away from the printing roller 6 moves synchronously, thereby realizing the deflection of the deflection block 42, and then driving the connecting rod 51 to deflect.

[0033] The connecting rod 51 passes through the rotating rod 5 and is fixed to the rotating rod 5 . The cross section of the wiping block 52 is an isosceles triangle. The two ends of the rotating rod 5 are flush with the two ends of the printing cylinder 6 . The diameter of the printing cylinder 6 is slightly smaller than the width of the ink tray 3 .

[0034] Specifically, the deflection of the connecting rod 51 drives the rotating rod 5 to deflect, thereby causing the wiping block 52 on one side to deflect, so that the side of the wiping block 52 contacts the printing roller 6, and the ink on the surface of the printing roller 6 is evenly spread, and the ink is squeezed, leaving a thin layer on the surface of the printing roller 6. The wiping block 52 on the other side does not deflect, so that the wiping block 52 and the surface of the printing roller 6 are in line contact, which is convenient for completely scraping off the excess ink on the surface of the printing roller 6; the two ends of the rotating rod 5 are flush with the two ends of the printing roller 6, so that the rotating rod 5 completely covers the surface of the printing roller 6; the diameter of the printing roller 6 is slightly smaller than the width of the ink tray 3, so that the printing roller 6 can be more fully inked.

[0035] A first output shaft 62 is provided at both ends of the printing roller 6. The first output shaft 62 at one end passes through the vertical plate 1 on one side and the side wall of the control box 11 and is connected to the control device 13; the first output shaft 62 at the other end is connected to the vertical plate 1 on the other side, and a first bearing 64 is provided at the connection between the vertical plate 1 and the vertical plate 1.

[0036] Specifically, the control device 13 controls the first output shaft 62 to rotate, so that the printing cylinder 6 rotates, driving the paper on the surface of the printing cylinder 6 to move, completing the printing work, and the printing cylinder 6 keeps rotating horizontally through the vertical plate 1 and the first bearing 64.

[0037] A pressure roller 61 is arranged on the top of the printing roller 6, and the two ends of the pressure roller 61 are flush with the two ends of the printing roller 6. The two ends of the pressure roller 61 are arranged with a second output shaft 63. The second output shaft 63 at one end passes through the vertical plate 1 on one side and the side wall of the vertical plate 1 and is connected to the control device 13; the second output shaft 63 at the other end is connected to the vertical plate 1 on the other side, and a second bearing 65 is arranged at the connection of the vertical plate 1.

[0038] Specifically, the paper passes by the pressure roller 61 and is placed on the top of the pressure roller 61. The printing roller 6 and the pressure roller 61 press the paper. The printing roller 6 and the pressure roller 61 rotate synchronously to drive the paper to move and complete the printing work. The vertical plate 1 and the second bearing 65 are used to keep the pressure roller 61 rotating horizontally.

[0039] During use, the control device 13 controls the rotation of the printing cylinder 6 and the pressure roller 61, so that the printing cylinder 6 is in rotational contact with the ink inside the ink tray 3. The control device 13 controls the lifting and lowering of the hydraulic rod 41, so that the side of the wiping block 52 on one side of the printing cylinder 6 is tangent to the side of the printing cylinder 6. The control device 13 then controls the slider 4 to move toward the printing cylinder 6, so that the wiping block 52 is in contact with the printing cylinder 6. When the printing cylinder 6 rotates, the ink on the surface of the printing cylinder 6 is evenly spread and the ink thickness on the surface of the printing cylinder 6 is reduced; the control device 13 controls the slider 4 on the other side to move toward the printing cylinder 6, so that the vertex of the wiping block 52 on the other side forms a line contact with the side of the printing cylinder 6, and the excess ink on the surface of the printing cylinder 6 is wiped clean.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
