Description

Technical Field

[0001] The utility model belongs to the technical field of digital printing, in particular to an automatic ink absorption adjustment device for digital printing. Background Art

[0002] With the development of printing technology, digital printing has become widely adopted. This is a new printing method that uses electronic text as a carrier and transmits it to digital printing equipment via the network to achieve direct printing. This method also requires the use of various types of ink. After the equipment has been printing for a period of time or has not printed for a long time, it needs to be pressed before use. After pressing the ink, the residual ink on the nozzle needs to be wiped clean. The general method is to wipe it manually or with a scraper. However, the large-format printing module base has many nozzles, and manual maintenance is inefficient. The automatic maintenance device with a scraper is efficient, but the effect is not as good as manual wiping. Therefore, a new device needs to be designed. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 3, the digital printing ink absorption automatic adjustment device includes a back plate 7, an ink absorption groove 2 is provided in front of the back plate 7, a pagoda joint 5 is installed in the middle of the bottom of the ink absorption groove 2, an ink absorption nozzle 1 is installed at the top of the ink absorption groove 2, and also includes two bearings 3 symmetrically installed at both ends of the ink absorption nozzle 1, two guide rails 4 are symmetrically installed in front of the back plate 7, and a first slider 10 and a second slider 12 are installed on the two guide rails 4 respectively, a rotating shaft 11 is installed in the middle of the first slider 10, and a slide groove 13 is provided in the middle of the second slider 12, a limit pin 14 is installed in the slide groove 13, and a second spring 15 is provided below the limit pin 14, the top of the second spring 15 is connected to the bottom of the ink absorption groove 2, and the rotating shaft 11 and the limit pin 14 are respectively connected to the two ends of the bottom of the ink absorption groove 2.

[0018] Furthermore: two support plates 8 are symmetrically installed at the upper and lower ends of the guide rail 4, an adjusting screw 9 is installed on the upper support plate 8, and a first spring 6 is installed on the lower support plate 8 to facilitate the rotation of the adjusting screw 9. Under the support of the support plate 8, the first slider 10 and the second slider 12 are pushed up to move along the guide rail 4. At the same time, the elastic force of the first spring 6 pushes up the first slider 10 and the second slider 12 to make them close to the adjusting screw 9; the guide rail 4 and the support plate 8 are respectively bolted to the back plate 7, which is convenient for disassembly and assembly of the guide rail 4 and the support plate 8; the slide groove 13 is a long slot with an arc, and is vertically arranged to facilitate the flexible movement of the limit pin 14 along the slide groove 13.

[0019] Working principle: Fix the back plate 7 to the digital printer with bolts, rotate the adjusting screw 9, and under the support of the support plate 8, push the first slider 10 and the second slider 12 to move along the guide rail 4 respectively. At the same time, the elastic force of the first spring 6 pushes up the first slider 10 and the second slider 12, so that they are close to the adjusting screw 9. When the nozzle has finished pressing the ink and the bottom plate moves to above the ink suction nozzle 1, it first contacts with the bearing 3. The bearing 3 rolls and presses down the ink suction nozzle 1 and the ink suction groove 2, so that the ink suction nozzle 1 and the ink suction groove 2 move downward along the guide rail 4. The first slider 10 and the second slider 12 compress the first spring 6 to form a reverse thrust. At the same time, one end of the bottom of the ink suction groove 2 is centered on the rotating shaft 11, and the other end is pushed by the elastic force of the second spring 15 to move along the slide groove 13 through the limit pin 14 to rotate, so that the ink suction nozzle 1 is close to the bottom plate of the nozzle, and the pagoda joint 5 is connected to the vacuum cleaner through a hose to suck out the residual ink on the nozzle.
