Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing machines, in particular to a printing machine ink flying prevention device and method. BACKGROUND

[0002] In the printing industry, especially in high-speed printing processes, ink flying has always been a technical problem that needs to be solved. Traditional printing machine designs often ignore the dynamic characteristics of ink during high-speed transmission, resulting in ink being thrown out when the roller is rotating at high speed, forming a flying phenomenon. This not only causes contamination of the printed product, affecting the printing quality, but also wastes a large amount of ink, increasing production costs.

[0003] In addition, the existing printing machine design in terms of ink flying prevention is usually simple, such as only trying to reduce flying by adding a baffle or changing the material of the roller. However, these methods often have limited effect and cannot fundamentally solve the problem of ink flying. At the same time, they may also affect the normal operation of the printing machine, such as increasing friction, reducing printing speed, etc.

[0004] In addition, the long-term operation of the printing machine requires close cooperation and stable operation between various components. However, traditional printing machines often have deficiencies in component design and material selection, resulting in serious wear and corrosion problems between components. This not only reduces the service life of the printing machine, but also increases maintenance costs.

The second rotating shaft 18 is rotatably connected to one side of the wall plate 2 and is located below the first rotating shaft 4. The outer part of the second rotating shaft 18 is fixedly connected with a printing roller 19. The other side of the device main body 1 is provided with a spraying mechanism.

[0043] The bearing 7 is slidably connected to the outer part of the fixed plate 3. The outer part of one group of the first rotating shafts 4 is fixedly connected with a driving motor 9. The outer part of the other group of the first rotating shafts 4 is fixedly connected with a gear 8.

[0044] The ink scraping plate 15 is slidably connected with the mesh roller 5 and the rubber roller 6. The upper side of the ink scraping plate 15 is fixedly connected with an ink groove cover 17, and the side edge of the ink groove cover 17 is slidably connected with the mesh roller 5 and the rubber roller 6.

[0045] The spraying mechanism comprises a circuit box 21, a fan 22, and a printing air outlet 23. The circuit box 21 is fixedly connected with the device main body 1. The fan 22 is fixedly connected to the bottom of the circuit box 21. The printing air outlet 23 is fixedly connected to the upper side of the device main body 1 and is located directly above the fan 22. The bottom of the device main body 1 is fixedly connected with track wheels 24, and the number of the track wheels 24 is several groups and is arranged in an array.

[0046] The working principle of the printing machine ink flying prevention device based on the embodiment is as follows: first, the device main body 1 serves as a support platform of the whole system, and two groups of symmetrical first rotating shafts 4 are fixed on the wall plate 2, wherein a group of the first rotating shafts 4 are provided with a meshing roller 5 for uniformly applying ink, and the other group of the first rotating shafts 4 are provided with a rubber roller 6 for working cooperatively with the meshing roller 5 to ensure uniform transmission of the ink, thereby improving the printing quality and making the water more stable in the transmission process and reducing the possibility of splashing;

[0047] In order to further prevent the ink from splashing, the fixed plate 3 is designed on the outer side of the wall plate 2 for supporting and fixing the bearing 7, so that the bearing 7 is completely isolated from the water ink, thereby avoiding damage of the corrosiveness and adhesion of the water ink to the oil seal of the bearing 7, and ensuring long-term stable operation of the printing machine.

[0048] In addition, the ink scraping plate 15 is clamped with the spring 14 on the fixed shaft 13 through the clamping groove 16, so that the ink scraping plate 15 can adaptively adjust the adhesion with the meshing roller 5 and the rubber roller 6; in the printing process, the ink scraping plate 15 is closely attached to the roller to effectively scrape off the excess ink and prevent the ink from being brought up and splashed in high-speed operation; meanwhile, the ink scraping plate 15 is made of wear-resistant and corrosion-resistant nylon material, which can maintain stable ink scraping effect for a long time.

[0049] The spraying mechanism further enhances the ink flying prevention capability of the printing machine, and the spraying mechanism controls the operation of the fan 22 through the circuit box 21 to uniformly spray lubricant or coolant on the key components of the printing machine, such as the gear 8, the meshing roller 5 and the rubber roller 6, which not only reduces the friction and wear between the components and improves the overall performance of the printing machine, but also reduces the adhesion and splashing of the ink through the lubricating effect.

[0050] The application also provides a method for preventing ink flying, which comprises the following steps:

[0051] Firstly, the fixed plate 3 of the rubber roller 6 and the meshing roller 5 is designed and placed on the outer side of the wall plate 2 to be completely isolated from the water ink, so as to avoid damage of the corrosiveness and adhesion of the water ink to the oil seal of the bearing 7, thereby ensuring long-term stable operation of the printing machine.

[0052] Then, the spraying lubricating system is used to lubricate the rubber roller 6, the meshing roller 5 and the fixed plate 3 on the side of the gear 8, so that these components are more durable and stable in high-speed operation. The spraying system can uniformly spray lubricant to ensure that all key components are fully lubricated, reduce friction and wear, and improve the overall performance of the printing machine.

[0053] Finally, during the printing process, the ink scraping plate 15 made of nylon material is used to contact the rubber roller 6 and the mesh roller 5. The ink scraping plate 15 is provided with a spring 14 at the back, which can automatically adjust the contact degree according to the running speed of the roller. This design can effectively scrape off the excess ink on the roller, prevent the ink from being lifted and splashed during high-speed operation, thereby reducing the ink flying phenomenon, improving the printing quality and efficiency. At the same time, the ink scraping plate 15 made of nylon material has the characteristics of wear resistance and corrosion resistance, and can maintain stable ink scraping effect for a long time.

[0054] Example 2.

[0055] During the use of the ink scraping plate 15 in Example 1, it is found that the contact between the ink scraping plate 15 and the rubber roller 6 or the mesh roller 5 is uneven, which causes the contact between the ink scraping plate 15 and the rubber roller 6 or the mesh roller 5 to be prone to gaps, resulting in ink missing and splashing. In order to improve the above problems, the ink scraping plate 15 in Example 1 is improved in this embodiment. Specifically, as shown in Figure 9 and Figure 10As shown, the improved ink scraping plate A15A is externally provided with a clamping groove 16, one side of the wall plate 2 is fixedly connected with a fixed shaft A13A, the outer side of the fixed shaft A13A is fixedly connected with a spring A14A, the ink scraping plate A15A comprises a first ink scraping plate 151, a second ink scraping plate 152 and a bottom plate 153, the first ink scraping plate 151 and the second ink scraping plate 152 are respectively connected with the rubber roller 6 and the mesh roller 5, the bottom plate 153 is connected with four movable rods 156, two of which are connected with the first ink scraping plate 151 and the remaining two are connected with the second ink scraping plate 152, each movable rod 156 is arranged to have the same extrusion force on the first ink scraping plate 151 or the second ink scraping plate 152 so that the first ink scraping plate 151 and the second ink scraping plate 152 have the same extrusion force on the rubber roller 6 or the mesh roller 5; four pressure control cavities 154 are arranged in the bottom plate 153 and are in communication with each other so that the air pressure in the four pressure control cavities 154 is the same, a pressure control piston 155 is arranged in each pressure control cavity 154 and can move in the pressure control cavity 154, the four pressure control pistons 155 are respectively connected with the four movable rods 156; the pressure control cavity 154 and the outside are connected through a connecting channel which is narrower than the pressure control cavity 154, and the movable rod ends enter the pressure control cavity 154 through the connecting channel. The pressure control piston 155 divides the pressure control cavity 154 into two areas, one of which is in communication with the outside through an air duct 157 so that the area has a constant air pressure, and the other area is respectively connected with a connecting channel 158 which connects the four pressure control cavities 154; the two ends of the spring A14A are respectively connected with the bottom plate 153 and the wall plate 2, one end of the fixed shaft A13A is fixedly connected with the bottom plate 153 and the other end is movably connected with the wall plate 2, and under the elastic force of the spring A, the bottom plate 153 has a tendency to move towards the rubber roller 6 and the mesh roller 5, more specifically, a channel is arranged in the wall plate 2 and one end of the fixed shaft A13A can move in the channel.

[0056] As Figure 10 In use, the pressure control pistons 155 at the ends of the two movable rods 156 connected with the first ink scraping plate 151 receive the same pressure from the pressure control cavities 154 (the four movable rods, pressure control pistons and pressure control cavities have the same size and dimensions), so that the two movable rods 156 connected with the first ink scraping plate 151 have the same extrusion on the first ink scraping plate 151, so that the first ink scraping plate 151 can be in contact with the rubber roller 6 on a larger plane, the contact force is uniform, and the ink is prevented from splashing. The mesh roller 5 has the same principle.

[0057] Further, since the first squeegee 151 and the second squeegee 152 are subjected to the same force of each of the moving rods 156, the force of the spring A14A to the bottom plate 2 can be evenly distributed to the two squeegees, further making the two squeegees evenly contact the rubber roller 6 and the mesh roller 5, avoiding the gap between the rubber roller 6, the mesh roller 5 and the squeegees, and preventing the ink from splashing.

[0058] More specifically, the connecting channel 158 is connected with an air pump (not shown in the figure), which can control the air pressure in the connecting channel 158, and further control the pressing force of the first squeegee 151 and the second squeegee 152 to the rubber roller 6 and the mesh roller 5, and further adjust according to the actual needs.

[0059] The first squeegee 151 and the second squeegee 152 can be separate or connected in contact in the lateral direction, and the cross section is usually smooth.

[0060] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
