Description

Technical Field

[0001] This application relates to the technical field of ink rollers, and particularly to an anti-leakage ink roller. Background Art

[0002] An ink roller is a key component used to transfer and coat ink during the printing process. It is usually made of metal or plastic and has a surface covered with a polymer material such as rubber or silica gel. These rollers play a crucial role in printing machines or coating machines, ensuring that the ink or coating can be evenly coated on paper or other substrates to form the desired patterns or texts.

[0003] Chinese Patent with Publication No. CN214288428U discloses an ink three-roll grinder for convenient discharging, which includes a frame. A first grinding roll, a second grinding roll, and a third grinding roll are provided on the frame. The first grinding roll, the second grinding roll, and the third grinding roll are connected with a transmission device. Baffle plates are provided at both ends of the connection between the first grinding roll and the second grinding roll, and the baffle plates are slidably connected to the frame.

[0004] During the printing process, the ink attached to the ink roller is gradually squeezed by the printed matter and accumulates towards both end faces of the ink roller. Although baffle plates are installed in the above technology, the baffle plates can only prevent the added ink from leaking to both ends of the ink roller, while the ink on the side where the ink roller rolls with the printed matter will still leak to both ends of the ink roller. The ink accumulated at the end of the ink roller will gradually leak to the frame, resulting in a large amount of ink that is difficult to clean on the frame, and the ink attached to the frame may affect the subsequent printed matter, which has deficiencies. Summary of the Utility Model

[0005] In order to improve the problem that the ink on the ink roller leaks to the frame, this application provides an anti-leakage ink roller.

[0006] The anti-leakage ink roller provided by this application adopts the following technical solution:

[0007] An anti-leakage ink roller includes a rotating shaft, on which a printing roller is coaxially arranged. Installation plates are arranged at both ends of the rotating shaft, and an anti-seepage component is arranged on the installation plates. The anti-seepage component is used to prevent the ink at the end of the printing roller from leaking onto the installation plates. The anti-seepage component includes an adjusting cylinder slidably arranged on the installation plate. A fixing part for fixing the adjusting cylinder is arranged on the installation plate. The inside of the adjusting cylinder is hollow and open at one end facing the printing roller. The rotating shaft coaxially rotates through the adjusting cylinder. An end shaft seat is detachably arranged on the installation plate, and the rotating shaft is rotationally matched with the end shaft seat. A partition plate is coaxially arranged on the adjusting cylinder. There is a gap between the circumferential inner wall of the adjusting cylinder and the circumferential outer wall of the rotating shaft. An ink removing component is arranged on the installation plate, and the ink removing component is used to remove the ink at the end of the printing roller.

[0008] By adopting the above technical solution, when the printing roller with ink is used to print printed matter, the ink attached to the printing roller is squeezed by the printed matter to the end of the printing roller. At this time, the partition plate will separate the end of the printing roller from the installation plate, thereby reducing the possibility that the ink at the end of the printing roller splashes onto the installation plate under the action of the centrifugal force of the rotating printing roller. At the same time, the ink leaking from the printing roller to the rotating shaft is surrounded by the adjusting cylinder, thereby preventing the possibility of ink leakage to the installation plate.

[0009] Optionally, the fixing part includes a positioning ring arranged on the installation plate, and a locking screw is threadedly connected to the positioning ring. The locking screw is used to press against the outer wall of the adjusting cylinder.

[0010] By adopting the above technical solution, after the worker adjusts the distance position between the adjusting cylinder and the printing roller, the locking screw is tightened, and the locking screw fixes the adjusting cylinder on the installation plate, which is beneficial to improving the adaptability to printing rollers of different lengths.

[0011] Optionally, the ink removing component includes an adjusting rod slidably arranged on the partition plate. A kidney-shaped hole for the adjusting rod to slide is formed on the partition plate. Positioning nuts are threadedly connected to both sides of the partition plate on the adjusting rod. A scraping plate with an L-shaped cross section is arranged on the adjusting rod. The L-shaped concave part of the scraping plate is stuck on the edge of the end of the printing roller. The open end of the adjusting cylinder abuts against the end of the printing roller. An ink inlet slot is formed on the adjusting cylinder. One end of the scraping plate extends to the ink inlet slot. A drain component is arranged on the adjusting cylinder, and the drain component is used to drain the ink in the adjusting cylinder.

[0012] By adopting the above technical solution, the worker adjusts the position of the adjusting rod to make the scraping plate stuck on the edge of the end of the printing roller, and then tightens the positioning nut. When the printing roller rotates, the ink at the end of the printing roller flows into the inside of the adjusting cylinder through the ink inlet notch under the scraping and guiding action of the scraping plate, and then the ink inside the adjusting cylinder is discharged through the ink discharging member, which is beneficial to reducing the possibility of ink splashing due to excessive accumulation at the end of the printing roller.

[0013] Optionally, the ink discharging member includes a spiral blade arranged on the rotating shaft. The spiral blade is located inside the adjusting cylinder. A collecting box with a hollow interior and an open end is arranged on the adjusting cylinder. A pull-out box is slidably arranged on the opening of the collecting box. A drain pipe is communicated between the closed end of the adjusting cylinder and the collecting box.

[0014] By adopting the above technical solution, when the printing roller rotates, the printing roller drives the spiral blade to rotate through the rotating shaft. The rotating spiral blade conveys the ink flowing in from the ink inlet notch to the closed end of the adjusting cylinder, and then flows into the pull-out box in the collecting box through the drain pipe. The worker can clean the pull-out box regularly.

[0015] Optionally, the scraping plate is arranged obliquely towards the ink inlet notch in the direction from top to bottom.

[0016] By adopting the above technical solution, the ink scraped by the scraping plate can quickly flow along the inclined scraping plate to the ink inlet notch, which is beneficial to shortening the time for the scraped ink to flow.

[0017] Optionally, a support ring is rotatably fitted on the rotating shaft inside the adjusting cylinder. A plurality of support rods are circumferentially and evenly arranged between the circumferential outer wall of the support ring and the circumferential inner wall of the adjusting cylinder.

[0018] By adopting the above technical solution, the ink conveyed by the spiral blade flows to the closed end of the adjusting cylinder through the gaps between the support rods. At the same time, the support ring and the support rods play a supporting role for the rotating shaft, which is beneficial to reducing the possibility of the rotating shaft deforming.

[0019] Optionally, sealing rings are arranged between the adjusting cylinder and the rotating shaft, and between the adjusting cylinder and the end of the printing roller.

[0020] By adopting the above technical solution, it is beneficial to reducing the possibility of ink leakage inside the adjusting cylinder.

[0021] Optionally, an anti-rotation plane is axially opened on the outer side wall of the adjusting cylinder, and the end of the locking screw abuts against the anti-rotation plane.

[0022] By adopting the above technical solution, it is beneficial to reducing the possibility of the adjusting cylinder rotating.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the printing roller prints a printed matter with attached ink, the ink attached to the printing roller is squeezed to the end of the printing roller by the printed matter. At this time, the isolation plate separates the end of the printing roller from the mounting plate, thereby reducing the possibility of the ink at the end of the printing roller splashing onto the mounting plate under the action of the centrifugal force during the rotation of the printing roller. At the same time, the ink leaking from the printing roller to the rotating shaft is surrounded by the adjusting cylinder, thereby preventing the possibility of the ink leaking to the mounting plate;

[0025] 2. The worker adjusts the position of the adjusting rod so that the scraping plate is stuck on the edge of the end of the printing roller, and then tightens the positioning nut. When the printing roller rolls, the ink at the end of the printing roller flows into the inside of the adjusting cylinder through the ink inlet notch under the scraping and guiding action of the scraping plate, and then the ink inside the adjusting cylinder is discharged through the ink discharging member, which is beneficial to reducing the possibility of excessive accumulation and splashing of the ink at the end of the printing roller;

[0026] 3. When the printing roller rolls, the printing roller drives the spiral piece to rotate through the rotating shaft. The rotating spiral piece transports the ink flowing in from the ink inlet notch to the closed end of the adjusting cylinder, and then flows through the drain pipe into the pull-out box in the collection box, and the worker can clean the pull-out box regularly.

Detailed Embodiment

[0031] The following further elaborates on the present application in conjunction with the attached Figures 1-3 for a more detailed description of the present application.

[0032] An embodiment of the present application discloses an ink roller with anti-leakage function.

[0033] Reference Figure 1 , a leak-proof ink roller includes a rotating shaft 1, a printing roller 2 is integrally formed coaxially on the rotating shaft 1, mounting plates 3 are arranged at both ends of the rotating shaft 1, a leak-proof component 4 is arranged on the mounting plates 3, and the leak-proof component 4 is used to prevent the ink at the end of the printing roller 2 from leaking onto the mounting plates 3. A de-inking component 5 is arranged on the mounting plates 3, and the de-inking component 5 is used to remove the ink at the end of the printing roller 2.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 , the leak-proof component 4 includes an adjusting cylinder 41 slidably arranged on the mounting plate 3, a fixing member 42 for fixing the adjusting cylinder 41 is arranged on the mounting plate 3.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 , the inside of the adjusting cylinder 41 is hollow and the end facing the printing roller 2 is open. The rotating shaft 1 rotates coaxially through the adjusting cylinder 41. An end shaft seat 43 is bolted to the mounting plate 3, a bearing 10 is arranged on the end shaft seat 43, the inner part of the bearing 10 is coaxially fixed to the end of the rotating shaft 1, a partition plate 44 is coaxially welded to the adjusting cylinder 41, and there is a gap between the circumferential inner side wall of the adjusting cylinder 41 and the circumferential outer side wall of the rotating shaft 1.

[0036] The worker adjusts the position of the adjusting cylinder 41 according to the length of the printing roller 2, and then tightens the locking screw 422 to fix the adjusting cylinder 41 on the mounting plate 3. When the printing roller 2 rotates, the ink attached to the printing roller 2 is squeezed by the printed matter to the end of the printing roller 2. At this time, the partition plate 44 on the adjusting cylinder 41 separates the end of the printing roller 2 from the mounting plate 3, thereby reducing the possibility of the ink attached to the end of the printing roller 2 splashing onto the mounting plate 3.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 , the de-inking component 5 includes an adjusting rod 51 slidably arranged on the partition plate 44. A kidney-shaped hole 52 for the adjusting rod 51 to slide is formed on the partition plate 44. The length direction of the kidney-shaped hole 52 is arranged along the radial direction of the axis of the rotating shaft 1. Positioning nuts 53 are threadedly connected to both sides of the partition plate 44 on the adjusting rod 51. A scraper 54 with an L-shaped cross section is welded to the adjusting rod 51, and the L-shaped concave part of the scraper 54 is stuck on the edge of the end of the printing roller 2.

[0038] Reference Figure 1 、 Figure 2 andFigure 3 The squeegee 54 is arranged obliquely towards the ink inlet slot 55 in the direction from top to bottom. The open end of the adjusting cylinder 41 abuts against the end of the printing roller 2. Sealing rings 8 are arranged between the adjusting cylinder 41 and the rotating shaft 1 and between the adjusting cylinder 41 and the end of the printing roller 2. An ink inlet slot 55 is formed in the adjusting cylinder 41. One end of the squeegee 54 that obliquely approaches the axis of the rotating shaft 1 extends to the ink inlet slot 55.

[0039] Refer to Figure 1 、 Figure 2 and Figure 3 An ink discharging member 56 is arranged on the adjusting cylinder 41. The ink discharging member 56 is used for discharging the ink in the adjusting cylinder 41. The ink discharging member 56 includes a spiral piece 561 welded to the rotating shaft 1. The spiral piece 561 is wound around the rotating shaft 1 and is located inside the adjusting cylinder 41. A collecting box 562 which is internally hollow and has an open end is arranged on the adjusting cylinder 41.

[0040] Refer to Figure 1 、 Figure 2 and Figure 3 A pull-out box 563 is slidably arranged on the opening of the collecting box 562. A drain pipe 564 is communicated between the closed end of the adjusting cylinder 41 and the collecting box 562. A support ring 6 is rotatably fitted on the rotating shaft 1 inside the adjusting cylinder 41. A plurality of support rods 7 are circumferentially and evenly welded between the circumferential outer side wall of the support ring 6 and the circumferential inner side wall of the adjusting cylinder 41.

[0041] The worker adjusts the position of the adjusting rod 51 according to the diameter of the printing roller 2 so that the squeegee 54 is stuck on the edge of the end of the printing roller 2, and then tightens the positioning nut 53. When the printing roller 2 rolls, the ink extruded to the end of the printing roller 2 is scraped off by the squeegee 54. The scraped ink flows along the inclined squeegee 54 to the ink inlet slot 55 on the adjusting cylinder 41 under the action of gravity and flows into the adjusting cylinder 41 through the ink inlet slot 55.

[0042] The printing roller 2 drives the spiral piece 561 to rotate through the rotating shaft 1. The rotating spiral piece 561 conveys the ink flowing into the adjusting cylinder 41 to the closed end of the adjusting cylinder 41. Under the sealing action of the sealing ring 8, the ink is conveyed to the closed end of the adjusting cylinder 41 through the gaps between the support rods 7. The ink at the closed end of the adjusting cylinder 41 flows into the pull-out box 563 on the collecting box 562 through the drain pipe 564 under the action of gravity, and then the worker can clean the pull-out box 563 regularly.

[0043] The implementation principle of a leak-proof ink roller in an embodiment of the present application is as follows: Workers adjust the position of the adjusting cylinder 41 according to the length of the printing roller 2, and then tighten the locking screw 422 to fix the adjusting cylinder 41 on the mounting plate 3. When the printing roller 2 rotates, the ink attached to the printing roller 2 is squeezed by the printed matter to the end of the printing roller 2. At this time, the partition plate 44 on the adjusting cylinder 41 separates the end of the printing roller 2 from the mounting plate 3, thereby reducing the possibility of the ink attached to the end of the printing roller 2 splashing onto the mounting plate 3.

[0044] Workers adjust the position of the adjusting rod 51 according to the diameter of the printing roller 2, so that the scraping plate 54 is stuck on the edge of the end of the printing roller 2, and then tighten the positioning nut 53. When the printing roller 2 rolls, the ink squeezed to the end of the printing roller 2 is scraped off by the scraping plate 54. The scraped ink flows along the inclined scraping plate 54 to the ink inlet notch 55 on the adjusting cylinder 41 under the action of gravity, and flows into the adjusting cylinder 41 through the ink inlet notch 55.

[0045] The printing roller 2 drives the spiral blade 561 to rotate through the rotating shaft 1. The rotating spiral blade 561 transports the ink flowing into the adjusting cylinder 41 to the closed end of the adjusting cylinder 41. Under the closing action of the sealing ring 8, the ink is transported to the closed end of the adjusting cylinder 41 through the gap between the support rods 7. The ink at the closed end of the adjusting cylinder 41 flows into the drawer box 563 on the collection box 562 through the drain pipe 564 under the action of gravity, and then workers can clean the drawer box 563 regularly.

[0046] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
