Therefore, flexographic printing presses are widely used in packaging printing, label printing, and commercial printing. The high-efficiency ink coating structure of the flexographic printing press is a tool for evenly spreading ink on the inking roller, and its function is to ensure the quality of printing.

[0003] However, existing flexographic printing presses with high-efficiency ink uniform coating structures have the following problems when in use:

[0004] Due to different usage environments, the required ink thickness on the inking roller varies. Therefore, it is necessary to adjust the spacing between the uniform coating structure and the inking roller. However, the existing high-efficiency ink uniform coating structure of flexographic printing presses does not make it convenient to adjust the spacing between it and the inking roller, making the device difficult to adapt to different usage environments and increasing the limitations of the device's use.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing high-efficiency ink uniform coating structure for flexographic printing presses. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency ink uniform coating structure for flexographic printing presses, in order to solve the problem mentioned in the background art that the existing high-efficiency ink uniform coating structures for flexographic printing presses are inconvenient to adjust the distance between themselves and the inking roller, making it difficult for the device to adapt to different usage environments and increasing the limitations of the device's use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency ink uniform coating structure for a flexographic printing machine, comprising an ink tank, an ink roller mechanism, a sprocket mechanism, and a servo motor. The ink roller mechanism is installed at the upper end of the ink tank, and positioning posts are fixed at both ends of the upper surface of the ink tank. A limiting mechanism is installed on the outer wall of the ink tank on the side of the positioning posts, and a support frame is sleeved on the outer wall of the positioning posts. A left sleeve and a right sleeve are respectively provided on the inner walls of both sides of the support frame. Lifting rods are installed on the inner walls of the left sleeve and the right sleeve, and a uniform coating scraper is fixedly connected to the lower end of the lifting rod. A secondary gear is fixedly installed on the upper outer wall of the right sleeve, and a servo motor is provided on the upper surface of the support frame on the side of the right sleeve.

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency ink uniform coating structure for flexographic printing machines, including an ink tank 1, an ink roller mechanism 2, positioning posts 3, a limiting mechanism 4, an adjusting rod 401, a clamping bracket 402, a support frame 5, a left sleeve 6, a right sleeve 7, a sprocket mechanism 8, a lifting rod 9, a uniform coating scraper 10, a secondary gear 11, a servo motor 12, and a main gear 13. The ink roller mechanism 2 is installed at the upper end of the ink tank 1, and positioning posts 3 are fixed at both ends of the upper surface of the ink tank 1. The ink tank is located on the side of the positioning posts 3. A limiting mechanism 4 is installed on the outer wall, and a support frame 5 is sleeved on the outer wall of the positioning column 3. At the same time, a left sleeve 6 and a right sleeve 7 are respectively provided on the inner walls of both sides of the support frame 5. A lifting rod 9 is installed on the inner walls of the left sleeve 6 and the right sleeve 7 respectively. A uniform coating scraper 10 is fixedly connected to the lower end of the lifting rod 9. A secondary gear 11 is fixedly installed on the upper outer wall of the right sleeve 7. A servo motor 12 is provided on the upper surface of the support frame 5 on the side of the right sleeve 7. A main gear 13 is fixedly connected to the upper end of the output shaft of the servo motor 12.

[0025] The ink tank 1 and the support frame 5 are in close contact, and the support frame 5 and the positioning column 3 form a sliding structure, which makes it convenient for the user to move the support frame 5 relative to the ink tank 1 and the positioning column 3 when moving and disassembling the support frame 5.

[0026] The limiting mechanism 4 includes an adjusting rod 401 and a bracket 402. The adjusting rod 401 is movably installed on the outer wall of the ink tank 1, and the bracket 402 is sleeved on the outer wall of the adjusting rod 401, so as to limit the support frame 5 through the limiting mechanism 4, thereby ensuring the stability of the support frame 5 in the ink tank 1.

[0027] The adjusting rod 401 is rotatably connected to the ink tank 1, making it easy for the user to rotate the adjusting rod 401.

[0028] The adjusting rod 401 and the holder 402 are threadedly connected, and the holder 402 is slidably connected to the ink tank 1 and the support frame 5 respectively, so that when the adjusting rod 401 rotates, the holder 402 moves along the adjusting rod 401 and the ink tank 1, thereby moving the holder 402 to the outside of the support frame 5 to limit the support frame 5.

[0029] Both the left sleeve 6 and the right sleeve 7 form a rotating structure with the support frame 5, and the outer walls of the left sleeve 6 and the right sleeve 7 are connected by a sprocket mechanism 8, which makes it easy for the right sleeve 7 to drive the left sleeve 6 to rotate through the sprocket mechanism 8, so that the left sleeve 6 and the right sleeve 7 rotate relative to the support frame 5 at the same time.

[0030] The lifting rod 9 is threaded to the left sleeve 6 and the right sleeve 7 respectively, so that when the left sleeve 6 and the right sleeve 7 rotate, the lifting rod 9 can move vertically relative to the left sleeve 6 and the right sleeve 7, thereby adjusting the height of the uniform coating scraper 10.

[0031] The auxiliary gear 11 meshes with the main gear 13, which facilitates the servo motor 12 to drive the main gear 13, so that the auxiliary gear 11 drives the right sleeve 7 to rotate.

[0032] Working principle: When using the high-efficiency ink uniform coating structure of this flexographic printing press, firstly as follows... Figure 1-5 As shown, the user adjusts the distance between the uniform coating scraper 10 and the inking roller mechanism 2 according to their needs. At this time, the user starts the servo motor 12, which then drives the main gear 13 to rotate. Next, the main gear 13 drives the secondary gear 11 to rotate, which in turn drives the right sleeve 7 to rotate. Then, the right sleeve 7 drives the left sleeve 6 to rotate via the sprocket mechanism 8. At this time, the left sleeve 6 and the right sleeve 7 rotate simultaneously relative to the support frame 5. Then, the lifting rod 9 moves vertically relative to the left sleeve 6 and the right sleeve 7. The lifting rod 9 then drives the uniform coating scraper 10 to move vertically, thereby adjusting the height of the uniform coating scraper 10 and thus adjusting the distance between the uniform coating scraper 10 and the inking roller mechanism 2. Therefore, the device facilitates adjustment of the distance between the uniform coating structure and the inking roller, making the device suitable for various applications. The device is designed to be adaptable to different operating environments, increasing its flexibility. The user then activates the inking roller mechanism 2, which picks up ink from the ink tank 1 and transfers it to the adjacent printing roller. Simultaneously, the even coating scraper 10 scrapes the ink on the inking roller mechanism 2, evenly coating it. When the even coating scraper 10 has too much ink and needs cleaning, the user closes the inking roller mechanism 2. The user then rotates the adjusting rod 401, causing the holder 402 to move along the adjusting rod 401 and disengage from the support frame 5. The user then moves the support frame 5 away from the ink tank 1 and the positioning column 3, thus disassembling the support frame 5 and facilitating cleaning of the even coating scraper 10. Therefore, the device is convenient for cleaning and maintaining the even coating scraper 10.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
