Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing press technology, specifically to an ink supply mechanism for a printing press. Background Technology
[0002] A printing press is a mechanical device used to reproduce text and images onto paper or other materials. Depending on the technology and application, printing presses can be classified into various types, such as gravure printing presses, offset printing presses, and flexographic printing presses, each with its specific uses and advantages.
[0003] When using a printing press, ink needs to be printed onto the surface of the object through the printing roller. Therefore, ink needs to be discharged onto the printing roller. Existing ink supply devices require multiple ink outlets to be set up, and the ink needs to flow to the surface of the printing roller by its own fluidity. However, this free flow method is relatively slow, and if one set of ink outlets fails to work properly, it is more likely to cause the ink to fail to flow and fill. Therefore, we propose an ink supply mechanism for printing presses. Utility Model Content
[0004] The purpose of this invention is to provide an ink supply mechanism for a printing press to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an ink supply mechanism for a printing press, comprising a hollow conveying pipe, two sets of support frames fixedly connected to the bottom of the conveying pipe, mounting plates fixedly connected to the bottom of each of the two sets of support frames, multiple sets of mounting slots provided on the mounting plates, a supply mechanism for supplying ink provided on the conveying pipe, a uniform mechanism for driving the ink to be evenly placed provided on the conveying pipe, and a lifting mechanism for driving the uniform mechanism to be lifted provided on the uniform mechanism.
[0006] Furthermore, the supply mechanism includes a discharge pipe, a switch valve, and a feed pipe. Multiple sets of discharge pipes are installed through one side of the conveying pipe, and a switch valve is installed on the discharge pipe. A feed pipe is installed through one side of the top of the conveying pipe.
[0007] Furthermore, a guide seat with an arc-shaped top is fixedly connected to the top of the conveying pipe and outside the feeding pipe.
[0008] Furthermore, the uniformizing mechanism includes a lead screw, a slide rod, a lead screw sleeve, a connecting frame, a moving plate, and scrapers.

The lead screw sleeve and the sliding sleeve are fixedly connected through the connecting frame. A moving plate is fixedly connected to one side of the connecting frame, and two sets of scrapers are provided on one side of the moving plate.
[0009] Furthermore, the lifting mechanism includes a slide rail, a slider, a lifting frame, a drive wheel, and a first drive motor. A slide rail is fixedly installed on one side of the moving plate, and a scraper is slidably connected to the slide rail via a slider. A "U"-shaped lifting frame is fixedly connected between two sets of scrapers. A first drive motor is fixedly installed on one side of the moving plate, and an elliptical drive wheel is fixedly connected to the output end of the first drive motor. The outer wall of the drive wheel is in contact with the lifting frame.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4 This utility model provides a technical solution: an ink supply mechanism for a printing press, including a hollow conveying pipe 1, two sets of support frames 2 fixedly connected to the bottom of the conveying pipe 1, and mounting plates 3 fixedly connected to the bottom of each of the two sets of support frames 2. The mounting plates 3 have multiple sets of mounting grooves. The conveying pipe 1 is provided with a supply mechanism 4 for supplying ink, and the conveying pipe 1 is provided with a uniform mechanism 5 for driving the ink to be placed evenly. The uniform mechanism 5 is provided with a lifting mechanism 6 for driving the uniform mechanism 5 to be lifted.
[0019] The support frame 2 and mounting plate 3 facilitate the fixed installation of the conveying pipe 1, which can be filled with ink. The ink is then discharged through the supply mechanism 4, allowing it to fall evenly onto the printing roller. The uniform mechanism 5 can then reciprocate left and right, which facilitates the rapid and even movement of ink onto the printing roller. After the ink is filled, the lifting mechanism 6 can lift the uniform mechanism 5, thereby preventing the ink from flowing normally.
[0020] Please see Figure 1 , Figure 2 and Figure 3 The supply mechanism 4 includes a discharge pipe 7, a switch valve 8, and a feed pipe 9. Multiple sets of discharge pipes 7 are provided through one side of the conveying pipe 1. A switch valve 8 is provided on the discharge pipe 7. A feed pipe 9 is provided through one side of the top of the conveying pipe 1. A guide seat 10 with an arc-shaped top is fixedly connected to the top of the conveying pipe 1 and outside the feed pipe 9.
[0021] The feed pipe 9 is connected to an external feed pump via a connecting pipe. The ink is then discharged into the conveying pipe 1. After opening the switch valve 8, the ink can be evenly discharged through the discharge pipe 7. The top of the guide seat 10 is designed to be arc-shaped and can contact the external connecting pipe. This design can prevent the connecting pipe from bending when using ink supply.
[0022] Please see Figure 1 , Figure 2 and Figure 4 The uniformizing mechanism 5 includes a lead screw 11, a slide bar 12, a lead screw sleeve 13, a connecting frame 15, a moving plate 16, and scrapers 17. The lead screw 11 is rotatably connected to the top of the conveying pipe 1. A second drive motor 23 is fixedly installed on the top of the conveying pipe 1. The output end of the second drive motor 23 is fixedly connected to the lead screw 11. The lead screw sleeve 13 is threadedly connected to the outside of the lead screw 11. The slide bar 12 is fixedly connected to one side of the conveying pipe 1. A sliding sleeve 14 is slidably connected to the slide bar 12. The lead screw sleeve 13 and the sliding sleeve 14 are fixedly connected through the connecting frame 15. A moving plate 16 is fixedly connected to one side of the connecting frame 15. Two sets of scrapers 17 are provided on one side of the moving plate 16.
[0023] When the ink is evenly dispersed as needed, the second drive motor 23 drives the lead screw 11 to operate. The rotating lead screw 11 can drive the lead screw sleeve 13 to move, which can drive the connecting frame 15, which is limited by the slide rod 12 and the slide sleeve 14, to move back and forth. This allows the moving plate 16 and the scraper 17 to move back and forth, thereby making the ink evenly dispersed on the printing roller.
[0024] Please see Figure 1 , Figure 2 and Figure 4 The lifting mechanism 6 includes a slide rail 18, a slider 19, a lifting frame 20, a drive wheel 21, and a first drive motor 22. A slide rail 18 is fixedly installed on one side of the moving plate 16. A scraper 17 is slidably connected to the slide rail 18 via the slider 19. A U-shaped lifting frame 20 is fixedly connected between two sets of scrapers 17. A first drive motor 22 is fixedly installed on one side of the moving plate 16. An elliptical drive wheel 21 is fixedly connected to the output end of the first drive motor 22. The outer wall of the drive wheel 21 is in contact with the lifting frame 20.
[0025] After the ink is evenly dispersed, the first drive motor 22 drives the elliptical drive wheel 21 to rotate. Then, the horizontal drive wheel 21 can be rotated to a horizontal position, which can push the "U"-shaped lifting frame 20 in contact with the drive wheel 21 to rise. This drives the scraper 17 and the slider 19 to move upward along the slide rail 18, thereby raising the scraper 17 and preventing it from affecting the normal flow of the evenly dispersed ink.
[0026] Please see Figures 1-4 The conveying pipe 1, the discharge pipe 7, the supply pipe 9, and the scraper 17 are all made of stainless steel. The stainless steel components can prevent rust and contamination during ink conveying.
[0027] In use, the support frame 2 and mounting plate 3 facilitate the fixed installation of the conveying pipe 1. The conveying pipe 1 is filled with ink, which is then discharged through the supply mechanism 4, allowing the ink to fall evenly onto the printing roller. The evenness mechanism 5 can then reciprocate left and right, facilitating the rapid and even movement of ink onto the printing roller. After the ink is filled, the lifting mechanism 6 raises the evenness mechanism 5, preventing normal ink flow. The feed pipe 9 is connected to an external feed pump via a connecting pipe. Ink is then discharged into the conveying pipe 1. Opening the switch valve 8 allows the ink to be evenly discharged through the discharge pipe 7. The arc-shaped guide seat 10 at the top contacts the external connecting pipe, preventing the connecting pipe from being used by the ink supply system. When a bend occurs, and the ink needs to be evenly dispersed, the second drive motor 23 drives the lead screw 11 to operate. The rotating lead screw 11 can drive the lead screw sleeve 13 to move, which in turn drives the connecting frame 15, which is limited by the sliding rod 12 and the sliding sleeve 14, to move back and forth. This allows the moving plate 16 and the scraper 17 to move back and forth, thereby evenly dispersing the ink onto the printing roller. After the ink is evenly dispersed, the first drive motor 22 drives the elliptical drive wheel 21 to rotate, which then rotates the horizontal drive wheel 21 to a horizontal position. This pushes the "U"-shaped lifting frame 20, which is in contact with the drive wheel 21, to rise. This drives the scraper 17 and the slider 19 to move upward along the slide rail 18, thereby raising the scraper 17 and preventing it from affecting the normal flow of the evenly dispersed ink.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
