Description

Technical Field

[0001] The utility model relates to the technical field of ink flying mechanisms, in particular to an anti-ink flying mechanism for a gravure printing machine. Background Art

[0002] The printing process of a gravure printing press involves transferring ink to paper through the rotation of a plate roller. The plate roller, engraved with an image, is arranged horizontally, with 30% of its circumference immersed in ink. During the roller's rotation, a scraper promptly removes any unwanted ink floating on the roller's surface (the image area, due to its concave shape, retains the ink). The elastic surface of the rubber roller then presses the printed material, such as paper, against the roller's surface, effectively transferring the ink from the image to the printed material. During printing, the plate roller rotates at high speeds, and ink splashing (i.e., ink splattering) is particularly noticeable. The scraper, operating normally, cannot prevent ink splashing, resulting in ink spots on the printed paper, causing damage to the finished product and contaminating the machine surface, requiring regular and thorough cleaning, which can disrupt normal production. Therefore, a mechanism for preventing ink splashing in a gravure printing press has been proposed to address these issues. Utility Model Content

[0022] In this embodiment, positioning posts 4 are fixedly connected to both side walls of the middle portion of the printing mechanism 1 , and the two positioning posts 4 are symmetrical at the same level. At the same time, the two positioning posts 4 are fixedly connected to both sides below the outer baffle 3 .

[0023] Furthermore, the outer baffle 3 is arc-shaped, and there is a distance between the inner arc surface of the outer baffle 3 and the lower side of the ink transfer roller 2 .

[0024] The positioning posts 4 provided in the printing mechanism 1 are used to fix the outer baffle 3 below the printing mechanism 1 so that the outer baffle 3 is placed below the ink transfer roller 2 to block ink from flying.

[0025] Furthermore, a movable opening 301 is provided in the middle of the front side of the outer baffle 3 , and an extension groove 302 is provided inside the outer baffle 3 .

[0026] Furthermore, an opening is provided on the inner side below the outer baffle 3 , and the opening is communicated with the extension groove 302 , and the extension groove 302 is communicated with the movable opening 301 .

[0027] Furthermore, the inner baffle 5 is inserted into the extension groove 302 and is slidably connected thereto, and the upper middle portion of the front side of the inner baffle 5 is fixedly connected to the middle portion of the inner side of the lifting plate 6 .

[0028] Furthermore, rough surfaces are provided on both sides of the inner end surface of the lifting plate 6 , and the rough surfaces of the lifting plate 6 are in close contact with the front outer wall of the outer baffle 3 .

[0029] The inner baffle 5 is inserted into the outer baffle 3, and a movable opening 301 is reserved on the front of the outer baffle 3. When the inner baffle 5 is connected to the lifting plate 6, the lifting plate 6 can indirectly drive the inner baffle 5 to move inside the outer baffle 3 through the outside of the movable opening 301.

[0030] A collecting box 7 is fixedly connected between the two side walls below the printing mechanism 1, and the middle part of the collecting box 7 is connected to the discharge port 8. At the same time, the discharge port 8 is communicated with the inside of the collecting box 7. The collecting box 7 is placed below the outer baffle 3. The collecting box 7 is used to collect the flying ink on the outer baffle 3 and the inner baffle 5, and then collect it into the corresponding barrel through the discharge port 8.

[0031] Working principle:

[0032] The outer baffle plate 3 is provided with a positioning column 4 and an outer baffle plate 3 under the printing mechanism 1. The positioning column 4 is used to limit the outer baffle plate 3 under the ink delivery roller 2, so that a part of the ink flying from the ink delivery roller 2 will splash onto the inner arc surface of the outer baffle plate 3, and at the same time, these flying inks will flow downward along the inner arc surface of the outer baffle plate 3. A sliding inner baffle plate 5 is inserted into the outer baffle plate 3, and a lifting plate 6 connected to the front of the inner baffle plate 5 is placed outside the movable opening 301 on the front of the outer baffle plate 3. In this way, when the lifting plate 6 is driven, the inner baffle plate 5 extends out from the inside of the outer baffle plate 3, and at the same time, the outer wall of the inner baffle plate 5 is tightly fitted with the inner wall of the extension groove 302 in the outer baffle 3, and the inner side of the lifting plate 6 is tightly fitted with the outer wall of the outer baffle 3. Then, the inner baffle plate 5 will not slide by itself after moving in the outer baffle plate 3, so that the inner arc surface of the inner baffle plate 5 blocks another part of the flying ink from the ink delivery roller 2.

[0033] In addition, when the inner baffle 5 is retracted into the outer baffle 3, the inner opening of the outer baffle 3 will scrape off the flying ink on the inner curved surface of the inner baffle 5. At this time, the scraped flying ink falls into the collection box 7 under the printing mechanism 1, and then flows out to the outside through the discharge port 8, and can be collected in a barrel filled with ink.
