Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing presses, in particular to a printing ink tank structure of a printing press. Background Art

[0002] A printing press first makes the text and images to be printed into a printing plate, installs it on the printing press, and then applies ink to the areas with text and images on the printing plate manually or by a printing press, and then transfers them directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby reproducing a printed product identical to the printing plate.

[0003] The ink tank is an essential component of a printing press. There is an ink roller above the ink tank. The ink roller rotates in the ink tank to transfer the ink in the ink tank to the ink roller for printing.

[0004] In the prior art, ink is usually added to the ink tank manually. During manual addition, if the height and speed of ink addition are not well controlled, the ink will fall into the ink tank and generate bubbles. The bubbles will rotate with the ink transfer roller and be printed on the product, affecting the production quality of the product. If the bubbles burst, ink will splash on the product, affecting the quality of the product. Utility Model Content

[0005] In order to overcome the above defects in the prior art, the utility model provides a printing ink tank structure of a printing press.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a printing ink tank structure of a printing machine, including a base, an ink tank is fixedly installed on the upper end of the base, a mounting box is arranged on one side of the ink tank, an ink transfer roller is movably installed in the middle of the mounting box, an ink delivery port is arranged on the right side of the mounting box, the right side of the ink delivery port is connected and communicated with the inside of the ink tank, a scraper is arranged on the left side of the ink delivery port, and the scraper is installed in contact with the ink transfer roller.

[0007] Furthermore, an ink inlet is arranged at the upper left of the installation box, and an ink storage chamber is arranged in the middle of the installation box, and the ink inlet is used to add ink into the ink storage chamber.

[0008] Furthermore, a plurality of groups of telescopic devices are fixedly mounted on the lower end of the ink storage chamber, and a sliding plate is fixedly mounted on the telescopic end of the telescopic device.

[0009] Furthermore, a sealing rubber is arranged on the outer side of the sliding plate, and the sealing rubber is in close contact with the inner wall of the ink storage chamber.

[0010] Furthermore, a connecting frame is fixedly installed on the left side of the base, and an installation box is fixedly installed on the left side of the connecting frame.

[0011] Furthermore, a filter screen can be detachably installed inside the left side wall of the ink tank, and the structural specifications of the filter screen correspond to those of the ink storage chamber.

[0012] The beneficial effect of the utility model is that ink is added into the ink inlet and enters the ink storage chamber. At this time, the ink is transferred to the right side by the clockwise rotation of the ink transfer roller. When the ink in the ink storage chamber is reduced, the sliding plate is moved upward by starting the telescopic device to assist in ink delivery. The ink is then scraped into the ink delivery port by a scraper and then enters the ink tank through the ink delivery port. The adding method is relatively smooth, does not generate bubbles, and does not affect the quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS
