Description

Technical Field

[0001] This utility model relates to the field of ink fountain technology, specifically to an anti-condensation ink fountain. Background Technology

[0002] The ink fountain is an important component of a printing press. It is responsible for providing the appropriate amount of ink to the printing plate to ensure that the printed products are bright and uniform in color. The ink fountain usually contains an ink fountain roller, which can coat the ink onto the printing plate. However, existing ink fountains still have certain defects in use.

[0003] In the prior art, the ink fountain of a printing press is usually installed at the top or bottom of the printing press. Ink can be added to the ink fountain through the feeding port. During long-term use, the ink on the inner surface of the ink fountain is prone to condensation, making it difficult for the condensed ink to adhere directly to the ink fountain roller, resulting in low printing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an anti-condensation ink fountain to solve the problem of easy condensation inside ink fountains currently on the market, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-condensation ink fountain, comprising: an ink fountain body, a feeding port, and an ink fountain roller. The ink fountain body has a feeding port at its top, and an ink fountain roller is provided on the inner side of the ink fountain body. A U-shaped frame is welded to the bottom of the ink fountain body, and a motor is installed inside the U-shaped frame. A rotating rod is connected between the output end of the motor and the inside of the ink fountain body. A first sealing ring is installed on the bottom of the ink fountain body near the rotating rod. A rotating block is welded to the outer side of the rotating rod. A fixing block is connected to the inner side of the U-shaped frame near the rotating block. A connecting rod is connected to the top of the rotating rod, and a connecting column is connected to the bottom of the connecting rod. A scraper is connected to the bottom of the connecting column.

[0006] Preferably, two sets of scrapers are arranged symmetrically about the center of the U-shaped frame.

[0007] Preferably, the rotating block and the fixed block form a sliding structure.

[0008] Preferably, a mounting base is welded to the outer side of the ink fountain body near the feeding port, and a lead screw is connected to the inside of the mounting base via a bearing.

[0009] Preferably, a movable block is threadedly connected to the outer side of the lead screw, and a sliding rod is connected to the side of the movable block near the ink fountain body.

[0010] Preferably, a doctor blade is connected to the end of the slide rod, and a second sealing ring is installed inside the ink fountain body near the slide rod.

[0011] Preferably, the top of the mounting base is connected to a connector via a rope, and the end of the connector is connected to a compression ball, which is made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the motor is running, the anti-condensation ink fountain can drive the rotating rod to rotate. When the rotating rod rotates, it can drive the rotating block and the connecting rod to rotate. When the rotating block rotates, it can rotate along the outside of the fixed block. When the connecting rod rotates, it can drive the scraper to rotate. When the scraper rotates, it can rotate and scrape inside the ink fountain body, locking the extrusion ball at the insertion end between the mounting base and the end of the lead screw, so that the extrusion ball will be extruded and deformed, thus making the lead screw less likely to rotate due to collision. By adjusting the distance between the doctor blade and the ink fountain roller, the ink content on the ink fountain roller can be adjusted, and at the same time, the doctor blade is less likely to loosen.

[0013] 1. The ink fountain is a crucial component of a printing press. During prolonged use, the ink inside the ink fountain can easily condense, preventing further printing. When the motor is running, it drives a rotating rod, which in turn rotates a rotating block and a connecting rod. The rotating block rotates along the outer edge of a fixed block, and the connecting rod rotates the scraper. The scraper continuously agitates the ink inside the ink fountain, preventing condensation. This continuous scraping effectively prevents ink condensation, ensuring that printing operations are not affected by ink buildup.

[0014] 2. In traditional ink fountains, the ink level is usually directly inside the ink fountain body during use, making it difficult to adjust the ink content on the ink fountain roller. When the lead screw rotates, it drives the moving block to slide closer to the ink fountain body. As the moving block moves, it drives the sliding rod to move. When the doctor blade tip moves to a specified position on the ink fountain roller surface, the rotation of the lead screw can be stopped, and the connector can be pulled. The extrusion ball at the end of the connector is locked between the mounting base and the end of the lead screw, causing the extrusion ball to deform under pressure. This prevents the lead screw from rotating due to collision. By adjusting the distance between the doctor blade and the ink fountain roller, the ink content on the ink fountain roller can be adjusted, and the doctor blade is less likely to loosen.

[0019] 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.

[0020] Please see Figure 1 and Figure 2 It is understood that this utility model provides a technical solution: an anti-condensation ink fountain, comprising: an ink fountain body 1, a feeding port 2, and an ink fountain roller 3. The ink fountain body 1 has a feeding port 2 at its top, and an ink fountain roller 3 is provided on the inner side of the ink fountain body 1. A U-shaped frame 4 is welded to the bottom of the ink fountain body 1. A motor 5 is installed inside the U-shaped frame 4. A rotating rod 6 is connected between the output end of the motor 5 and the inside of the ink fountain body 1. A first sealing ring 7 is installed at the bottom of the ink fountain body 1 near the rotating rod 6. A rotating block 8 is welded to the outer side of the rotating rod 6. A fixing block 9 is connected to the inner side of the U-shaped frame 4 near the rotating block 8. A connecting rod 10 is connected to the top of the rotating rod 6. A connecting column 11 is connected to the bottom of the connecting rod 10. A scraper 12 is connected to the bottom of the connecting column 11. Two sets of scrapers 12 are symmetrically arranged about the center of the U-shaped frame 4. A sliding structure is formed between the rotating block 8 and the fixing block 9.

[0021] In practical implementation, the ink fountain is a crucial component of the printing press. During prolonged use, the ink inside the ink fountain tends to condense, making subsequent printing operations impossible. When ink is added into the ink fountain body 1 through the feeding port 2, the motor 5 can be started. When the motor 5 runs, it drives the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives the rotating block 8 and the connecting rod 10 to rotate. When the rotating block 8 rotates, it can rotate along the outside of the fixed block 9. When the connecting rod 10 rotates, it drives the connecting column 11 to rotate. When the connecting column 11 rotates, it drives the scraper 12 to rotate. When the scraper 12 rotates, it can rotate and scrape inside the ink fountain body 1, so that the ink inside the ink fountain body 1 is continuously agitated by the scraper 12, thus preventing the ink inside the ink fountain body 1 from condensing.

[0022] See Figure 1 and Figure 2 It can be seen that by continuously scraping the ink with the scraper 12, the ink inside the ink fountain body 1 can be effectively prevented from condensing, thus ensuring that the printing operation will not be affected by ink condensation.

[0023] See Figures 1-3 It can be seen that an installation base 13 is welded to the outer side of the ink fountain body 1 near the feeding port 2. The inside of the installation base 13 is connected to a lead screw 14 through a bearing. The outer side of the lead screw 14 is threaded to a moving block 15. The side of the moving block 15 near the ink fountain body 1 is connected to a slide rod 16. The end of the slide rod 16 is connected to a doctor blade 17. A second sealing ring 18 is installed inside the ink fountain body 1 near the slide rod 16. The top of the installation base 13 is connected to a plug 19 through a rope. The end of the plug 19 is connected to a compression ball 20. The compression ball 20 is made of rubber. The slide rod 16 and the ink fountain body 1 form a sliding structure.

[0024] In practical implementation, traditional ink fountains are usually placed directly inside the ink fountain body 1 during use, making it difficult to adjust the ink content on the ink fountain roller 3. The screw 14 can be rotated forward. When the screw 14 rotates, it can drive the moving block 15 to slide threadedly closer to the ink fountain body 1. When the moving block 15 moves, it can drive the sliding rod 16 to move. When the sliding rod 16 moves, it can drive the doctor blade 17 to move closer to the ink fountain roller 3. When the end of the doctor blade 17 moves to a specified position away from the surface of the ink fountain roller 3, the rotation of the screw 14 can be stopped, and the insertion holder 19 can be pulled. The extrusion ball 20 at the end of the insertion holder 19 is locked between the mounting base 13 and the end of the screw 14, so that the extrusion ball 20 is deformed by extrusion, thus making the screw 14 less likely to rotate due to collision.

[0025] See Figures 1-3It can be seen that by adjusting the distance between the doctor blade 17 and the ink fountain roller 3, the ink content on the ink fountain roller 3 can be adjusted, and the doctor blade 17 is not easy to loosen.

[0026] In summary, when using this anti-condensation ink fountain, the motor 5 drives the rotating rod 6 to rotate, which in turn drives the rotating block 8 and the connecting rod 10 to rotate. The scraper 12 continuously scrapes the ink, effectively preventing ink condensation inside the ink fountain body 1, thus ensuring that the printing operation is not affected by ink condensation. The extrusion ball 20, which is inserted into the end of the 19, is locked between the mounting base 13 and the end of the lead screw 14, causing the extrusion ball 20 to deform under pressure, making it difficult for the lead screw 14 to rotate due to collision. By adjusting the distance between the doctor blade 17 and the ink fountain roller 3, the ink content on the ink fountain roller 3 can be adjusted, and the doctor blade 17 is not easy to loosen. The contents not described in detail in this description are prior art known to those skilled in the art.

[0027] 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.
