DETAILED DESCRIPTION

[0021] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0022] The utility model discloses a water-ink printing device for carton board production, comprising an ink box 1, fixed plates 2 are arranged on both sides of the ink box 1, a first guide window 21 is arranged on the fixed plate 2, a movable shaft a3 is arranged between the two first guide windows 21, the first guide windows 21 are arranged horizontally, so that the shaft a3 can move horizontally along the first guide windows 21, an ink wheel 31 is arranged on the shaft a3, a second guide window 22 is arranged on the fixed plate 2, and the second guide window 22 is arranged longitudinally. A shaft b4 is provided between the two second guide windows 22 and can be raised and lowered along the second guide windows 22. A printing wheel 41 that can abut against the ink wheel 31 is provided on the shaft b4. A groove corresponding to a pattern or text is engraved on the printing wheel 41. A shaft c5 is also provided between the two fixed plates 2. An ink scraper 51 that can abut against the printing wheel 41 is provided on the shaft c5. Both ends of the shaft a3 pass through the fixed plate 2 and are provided with a coupling 32. A power source that drives the ink wheel 31 to rotate is provided on the coupling 32. The motor 33 also includes two first cylinders 34 connected to the two couplings 32 respectively. The first cylinders 34 can drive the coupling 32 to move along the first guide window 21, so that the ink wheel 31 abuts against the printing wheel 41. Specifically, when printing is required, the power motor 33 drives the shaft a3 to rotate, so that the ink wheel 31 rolls in the ink in the ink box 1, and the two first cylinders 34 synchronously drive the coupling 32 to move, thereby causing the shaft a3 to move horizontally, and the ink wheel 31 stained with ink abuts against the printing wheel 41, so that the printing wheel 41 is printed. The brush wheel 41 is lifted and drives the printing wheel 41 to rotate. The ink on the ink wheel 31 is transferred to the surface of the printing wheel 41, so that the printing wheel 41 is attached with ink. During the rotation of the printing wheel 41, the ink scraper 51 abuts against the printing wheel 41 to scrape off the excess ink from the surface of the printing wheel 41, leaving only the ink in the pattern and text slots engraved by the printing wheel 41, so as to perform ink printing. The ink scraper 51 controls the ink thickness of the printing wheel 41, and scrapes the excess ink into the ink box 1 for reuse, saving resource consumption. Two symmetrical support plates 23 are arranged on the top of the fixed plate 2. The spacing between the two support plates 23 allows the printing wheel 41 to move. Conveyor belts 24 are arranged on both sides of the support plate 23, and a pressure plate mechanism 6 is arranged on the top. The two conveyor belts 24 cooperate with each other to transport the carton sheet to the top of the support plate 23, the pressing plate mechanism 6 moves downward to press the carton sheet, and the printing wheel 41 rises synchronously to print patterns or texts on the carton sheet. Through the cooperation of the first cylinder 34 and the pressing plate mechanism 6, the printing wheel 41 can print during the movement of the carton sheet. There is no need to stop the conveyor belt 24 during the printing process, and the printing speed is fast and the efficiency is high.

[0023] The ink box 1 is provided with a plurality of partitions 11, which divide the ink box 1 into a plurality of independent receiving grooves 12. After the carton sheet is formed into a carton, it has a plurality of sides, and the receiving grooves 12 correspond to the positions of these sides on the carton sheet, respectively, without installing other printing machines.

[0024] More specifically, each of the shafts a3, b4 and c5 is provided with an ink wheel 31, a printing wheel 41 and an ink scraper 51 in each receiving groove 12, so that printing operations can be performed simultaneously on multiple positions of the carton board, greatly improving the printing efficiency.

[0025] Each of the accommodating grooves 12 is provided with an ink delivery tube 13 for injecting ink. In this solution, the ink dye in each accommodating groove 12 is independent and does not communicate with other accommodating grooves 12, which can facilitate printing of inks of different colors and concentrations.

[0026] The second guide window is provided with a limit plate 221, on which a movable guide pin 222 is provided, and a limit block 223 that can abut against the shaft b4 is provided at the lower end of the guide pin 222, and a spring 224 is provided between the limit block 223 and the limit plate 221. The limit plate 221 is detachable, and the shaft b4 can be taken out by removing the limit plate 221, so as to facilitate the replacement of the printing wheel 41. After the first cylinder 34 drives the ink wheel 31 to reset, the elastic force provided by the spring 224 can make the shaft b4 quickly descend and reset, thereby improving the printing stability.

[0027] One end of the shaft c5 passes through a fixed plate 2 and is provided with a limit wheel 52, and the other end of the shaft c5 passes through another fixed plate 2 and is provided with a swing rod 53, including a second cylinder 54, and the second cylinder 54 can drive the swing rod 53 to swing, so that the ink scraper 51 abuts against the printing wheel 41. A connecting rod 55 is also movably connected between the swing rod 53 and the second cylinder 54, and the second cylinder 54 can drive the ink scraper 51 to swing slightly, so as to accurately control the thickness of the ink on the surface of the printing wheel 41.

[0028] The pressing plate mechanism 6 is provided with a roller 61, and fixed blocks 62 are provided on both sides of the roller 61. The pressing plate mechanism 6 is provided with a lifting device 63 that can drive the fixed blocks 62 to rise and fall. The utility model water-based ink printer does not need to stop the conveyor belt 24 during the printing process. The rolling speed of the roller 61 is consistent with the conveying speed of the conveyor belt 24. After the roller 61 contacts the carton sheet, it will not generate additional resistance to the carton sheet, and the printing structure has high stability.

[0029] The ink scraper 51 is provided with a scraper 511, and baffles 512 are provided on both sides of the scraper 511. Through the limitation of the baffles 512, the ink dye will flow to the ink box 1 along the scraper 511 when it is scraped off from the printing wheel 41, which can avoid the ink dye from splashing, save the consumption of ink resources, improve the cleanliness of the equipment, and have strong environmental protection ability.

[0030] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
