DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in combination with the drawings.

[0024] Please refer to Figure 1 , Figure 2 , an embodiment of the lining paper spraying ink device provided by the utility model, comprising a rack, the rack comprises two opposite and spaced apart wallboards 1, the two wallboards 1 are connected into one by a plurality of cross beams, according to the need, the wallboard 1 can also be provided with the existing structure such as reinforcing rib, reinforcing beam. The installation space is formed between the two wallboards 1, and the printing plate roller 3, the ink scraping knife 2, the ink groove 4 and the ink spraying plate 5 are arranged in the installation space. Of course, it can be understood that the upper side of the printing plate roller 3 is also provided with a printing pressure roller, a paper guide roller and the like, which are used to cooperate with the printing plate roller 3 to complete printing. The printing pressure roller, the paper guide roller and the like are not improved in the present application, so they are not shown in the drawing, and will not be described here.

[0025] The ink scraping knife 2 and the ink spraying plate 5 are both installed on the wallboard 1 and are located at opposite sides of the printing plate roller 3 respectively, and the ink scraping knife 2 and the ink spraying plate 5 are both inclinedly arranged, and the side edge close to the printing plate roller 3 is low. The ink groove 4 is located below the printing plate roller 3 and is used for receiving ink, which not only receives the ink falling from the printing plate roller 3, but also receives the excess ink on the ink spraying plate 5 and the ink scraped from the printing plate roller 3 by the ink scraping knife 2. The printing plate roller 3 is spaced apart from the ink groove 4 by 5-10cm, and the printing plate roller 3 does not directly contact the ink in the ink groove 4. One end of the ink groove 4 is provided with an ink outlet, and the ink outlet is connected with an ink barrel through a plastic ink guide pipe. The ink in the ink groove can directly flow to the ink barrel.

[0026] In order to achieve uniform ink pouring on the printing plate roller 3, as Figure 4 The ink spray plate 5 is shown with multiple ink spray tubes 7 installed. These tubes 7 are evenly distributed along the length of the ink spray plate 5, that is, along the axial direction of the printing plate roller 3. The ink spray tubes 7 are connected to an ink pump (not shown), which continuously delivers ink from the ink barrel to the ink spray tubes 7. Each ink spray tube 7 is equipped with a flow valve to effectively control the ink spray flow rate, ensuring that the ink completely covers the axial length of the printing plate roller 3. The ink collected by the ink tank 4 is then returned to the ink barrel. The number of ink spray tubes 7 can be one, two, or more; the ink outlet of the ink spray tube 7 is fan-shaped, ensuring that the ink is evenly sprayed in a fan-shaped manner.

[0027] While appropriately increasing the number of ink spray tubes 7 can improve the uniformity of ink distribution in the axial direction of the printing plate roller 3 to a certain extent, the ink spray tubes 7 need to be fixed, occupying a large space, having high manufacturing and installation costs, and having a complex structure. To overcome this problem, the ink spray plate 5 is provided with a first ink distribution groove 52 and a second ink distribution groove 54. The first ink distribution groove 52 and the second ink distribution groove 54 are separated by an ink barrier 53. In the direction of ink flow, the second ink distribution groove 54 is located downstream of the first ink distribution groove 52. An ink spray tube groove 51 is provided on the groove wall on the upstream side of the first ink distribution groove 52, and the ink spray tube 7 is fixed in the ink spray tube groove 51. At the same time, a plurality of overflow grooves 55 are provided on the ink barrier 53. The overflow grooves 55 are recessed into the upper side of the ink barrier 53 and connect the first ink distribution groove 52 and the second ink distribution groove 54. In this way, the first ink distribution groove 52 can collect the ink output from the ink spraying tube 7, initially distributing the ink evenly along the axial direction of the printing plate roller 3; the ink is then diverted and output to the second ink distribution groove 54 through multiple overflow grooves 55. The multiple overflow grooves 55 form multiple ink spraying effects similar to the ink spraying tube 7, so that the ink is evenly distributed along the entire axial direction of the printing plate roller 3. The downstream groove wall of the second ink distribution groove 54 is lower than the groove bottom wall of the overflow groove 55, and the ink is evenly delivered to the printing plate roller 3. The ink spraying plate 5 has a simple structure and is easy to process and manufacture.

[0028] Furthermore, the bottom of the first ink distribution groove 52 is tilted, with the upstream side of the groove being deeper than the downstream side. This not only reduces the amount of ink accumulated in the first ink distribution groove 52 but also guides the ink to converge downstream. The optimal distance between the ink plate 5 and the printing roller 3 is 0.5-3 mm, and the angle between the tangent line closest to the printing roller 3 and the printing roller 3 is preferably 60-80°.

[0029] In order to ensure that the distance between the ink-spraying plate 5 and the printing plate roller 3 is adjustable, an adjustment seat 6 is provided on the wall panel 1; Figure 3As shown, the adjusting seat 6 is provided with a first sliding groove 62; the first sliding groove 62 is a T-shaped groove and extends horizontally; a shower plate 63 is slidably arranged in the first sliding groove 62, and the shower plate 63 is slidably arranged in the first sliding groove 62 and can be moved close to or away from the printing plate roller 3. The two ends of the shower plate 5 are fixedly connected with the shower plate 63, and the connection mode can be welding, bonding or other fixed connection modes.

[0030] The end of the first sliding groove 62 away from the printing plate roller 3 is fixedly provided with a support seat 64, the support seat 64 is rotatably provided with a screw rod 65, the screw rod 65 is threadedly connected with the shower plate 63; rotating the screw rod 65 can drive the shower plate 63 to move close to or away from the printing plate roller 3.

[0031] In actual application, the printing plate roller 3 will be disassembled, and since the shower plate 5 is fixedly provided with the shower pipe 7 and the shower pipe 7 is also communicated with the ink conveying pipeline, the disassembly workload is large; in order to avoid the influence of the shower plate 5 on the operation; the adjusting seat 6 can move up and down relative to the wall plate 1. Specifically, the wall plate 1 is provided with a vertically extending guide groove 11, the adjusting seat 6 is provided with a limiting plate, the adjusting seat 6 partially penetrates through the guide groove 11 and is connected with the limiting plate, thereby forming a second sliding groove 61 on the adjusting seat 6, and the wall plate 1 is clamped into the second sliding groove 61 and can slide relative to the second sliding groove 61.

[0032] The wall plate 1 is provided with a pin shaft 12 and a rotating shaft 13, and the pin shaft 12 and the rotating shaft 13 are close to the upper end of the guide groove 11; the pin shaft 12 is plug-pullable, and the rotating shaft 13 is rotatably arranged on the wall plate 1. The two ends of the rotating shaft 13 are located on the two sides of the wall plate 1, and one end thereof located in the mounting space is fixedly connected with a support shaft 14, and the support shaft 14 rotates synchronously with the rotating shaft 13. When the shower plate 5 is normally working, the adjusting seat 6 is located at the lowermost end of the guide groove 11; when the printing plate roller 3 is disassembled, the adjusting seat 6 and the shower plate 5 are pushed to move upward together; after the adjusting seat 6 is higher than the rotating shaft 13, the pin shaft 12 is pulled out and the rotating shaft 13 is rotated to make the support shaft 14 supported on the lower side of the adjusting seat 6, and finally the pin shaft 12 is inserted into the lower side of the support shaft 14 to prevent the support shaft 14 from rotating downward.

[0033] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
