TECHNICAL FIELD
[0001] The utility model relates to printing technical field especially relates to an environmental protection type water-based ink printing device. BACKGROUND
[0002] The environmental protection type water-based ink printing device is a professional equipment for graphic and text transfer using water-based ink. The device uniformly applies water-based ink, which uses water as the main solvent, on the printing plate through precise control of the ink path system, and then transfers the ink to the surface of various printing materials under the action of pressure to achieve clear and exquisite printing effect. It is widely used in packaging printing, advertising production, label printing and other fields. Whether it is food and drug packaging, commodity label or poster, it can perfectly meet the requirements. Compared with traditional oil-based ink printing equipment, the biggest advantage is environmental protection. The emission of volatile organic compounds (VOCs) of water-based ink is very low, which significantly reduces the pollution to the environment and ensures the air quality of the production workshop, creating a healthier working environment for operators. It is a new type of printing equipment that conforms to the trend of green development.
[0003] During the operation of the environmental protection type water-based ink printing device, the water-based ink is stably delivered from the ink storage tank to the ink duct by the pump pressure, and then the ink is quantitatively transferred to the printing plate of the printing plate cylinder by the cooperation of the ink roller and the ink transfer roller. The ink is adsorbed on the graphic and text area of the printing plate by using the adsorption characteristics of the printing plate, and the blank part is not inked. Then, the printing plate cylinder and the impression cylinder rotate towards each other, and the ink on the printing plate is transferred to the surface of the printing material under the action of pressure, completing the graphic and text transfer. Finally, through hot air drying, infrared drying and other methods, the water-based ink on the surface of the printing material is quickly dried and solidified by using the volatility of water, so as to present clear and firm printing patterns. The whole process realizes the efficient printing of the environmental protection type ink with water as the solvent.
[0004] However, in the prior art, some environmentally friendly water-based ink printing devices have the problem of inconvenient pipeline connection. In actual operation, if not careful, the connection may not be tight. Once this happens, water-based ink will leak from the connection, which not only causes unnecessary waste of ink resources, increases production costs, and pollutes the surrounding production environment, posing a potential threat to the cleanliness and safety of the workshop. When the printing device is put into long-term use, the problem of inconvenient pipeline connection is further magnified due to factors such as natural aging of equipment, daily wear and tear, or the need for maintenance, relocation, or even simple replacement of a faulty section of the pipeline system due to production process upgrades or capacity expansion requirements. Maintenance personnel often need to invest several times the effort of conventional equipment maintenance to painstakingly disassemble and assemble a large number of connection components. This process not only consumes time and effort, significantly increasing equipment maintenance costs, but also leaves the equipment in a downtime state, forcing the entire production process to be interrupted. Production stagnation directly leads to a significant decline in production efficiency, significantly lengthening the order delivery cycle, and having a very adverse chain reaction on the normal production and operation order of the enterprise, to some extent, severely restricting the efficient development process and market competitiveness of the enterprise.

[0026] Embodiment one
[0027] As Figures 1 to 3As shown, the embodiment provides an environmentally friendly water-based ink printing device, an environmentally friendly water-based ink printing device, including a template 1, the top end of the template 1 is fixedly connected with a support 2, the inner wall of the support 2 is slidably connected with a moving plate 3, the moving plate 3 can be smoothly moved along a certain direction under the constraint of the support 2. The top end of the moving plate 3 is fixedly connected with a shell 4, which provides a relatively closed and stable working environment for the key components such as the limiting block 6 and the moving ring 8 in the interior, protects the internal structure from the interference of external environmental factors, the inner wall of the shell 4 is slidably connected with a plurality of limiting blocks 6, according to the operation of the control column 5, the movement of the moving ring 8 and the related structure is limited and guided. The top end of the far side of the plurality of limiting blocks 6 is respectively fixedly connected with a control column 5, when the operator pushes or pulls the control column 5, the control column 5 drives the limiting block 6 connected with it to slide in the inner wall of the shell 4.
[0028] By controlling the column 5, the position of the limiting block 6 can be flexibly adjusted, and the precise control of the movement of the internal moving ring 8 and other structures is realized, so that the device can adapt to different working scenes and operation requirements, and the functionality and flexibility of the device are enhanced. The bottom end of the side of the plurality of limiting blocks 6 is respectively fixedly connected with a contraction column 7, when the limiting block 6 slides under the driving of the control column 5, the contraction column 7 moves. The contraction column 7 plays a role of buffering and adjusting in the device, when the limiting block 6 moves to a certain position to limit the movement of the moving ring 8 and other structures, the contraction column 7 can absorb part of the impact force generated by the limiting through its elastic deformation, avoid rigid collision to damage the internal structure of the device, at the same time, it can also make the limiting process more stable and reliable, improve the service life and working stability of the device.
[0029] The inside of the shell 4 is slidably connected with a moving ring 8, which is connected with a plurality of connecting columns 9 and a pressing column 10, and transmits the force from the limiting block 6 and other structures to the contraction column 11 and other components below, drives these components to move cooperatively, realizes various functions of the device, the outside of the moving ring 8 is fixedly connected with a plurality of connecting columns 9, when the moving ring 8 slides in the shell 4, the connecting column 9 moves, and then drives the structure such as the sliding ring 19 connected with it to move, so that the movement between the components in the device is consistent, ensures that the device operates according to the predetermined working process, improves the working efficiency and accuracy of the device.
[0030] Multiple pressure columns 10 are fixedly connected to the bottom end of the moving ring 8. When the moving ring 8 slides downward, the pressure columns 10 move downward accordingly, applying pressure to the lower contraction column 11 and other components. The bottom ends of the multiple pressure columns 10 are each fixedly connected to a contraction column 11. When the pressure columns 10 move downward, the contraction columns 11 move downward accordingly. The contraction columns 11 function as a buffer and pressure regulator in the device. Springs 12 are fitted around the outside of each contraction column 11. When the contraction column 11 moves downward under pressure, the springs 12 are compressed, storing elastic potential energy; when the pressure decreases or disappears, the springs 12 extend, releasing the stored energy. Fixing components are fixedly connected to the bottom ends of the multiple springs 12, and a filtering component is fixedly connected to the front side of the template 1.
[0031] Example 2
[0032] like Figures 2 to 4 As shown, components identical or corresponding to those in Embodiment 1 are referenced using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the filter assembly includes an upper shell 21, the rear side of which is fixedly connected to the front side of the template 1. A lower shell 22 is fixedly connected to the bottom of the upper shell 21, forming a complete filter chamber. A large filter screen 23 is fixedly connected to the rear inner wall of the upper shell 21. When waste ink flows in from the top of the upper shell 21, it first contacts the large filter screen 23. Since the ink may contain large impurities, such as blocky pigment particles and paper scraps, the large filter screen 23 can effectively intercept these larger impurities with its larger mesh size, preventing them from entering subsequent filtration stages. A medium filter screen 24 is fixedly connected to the rear inner wall of the upper shell 21. After the waste ink has been initially filtered by the large filter screen 23, it continues to flow downwards, at which point the medium filter screen 24 begins to function.
[0033] The upper shell 21 has a small filter 25 fixedly connected to the inner wall of the middle section, which can intercept smaller impurities that the large filter 23 fails to filter out. After two stages of filtration by the large filter 23 and the medium filter 24, the waste ink is almost entirely reduced to extremely fine impurities, which are precisely intercepted by the small filter 25. The fine filtration function of the small filter 25 ensures that the ink flowing into the lower shell 22 achieves a high degree of purity, effectively preventing tiny impurities from clogging the output pipe 31 and the ink inlet of the ink storage tank 36, and ensuring the smooth operation of the ink processing system. The upper shell 21 has a vibration damping pad 27 fixedly connected to the inner wall of the front side. When waste ink flows into the upper shell 21 and impacts the filter, it will generate a certain impact force and vibration.
[0034] The damping pad 27 can effectively buffer the impact force and vibration by using its elastic deformation characteristics. The inner wall of the damping pad 27 is fixedly connected with the connecting pad 26, and the main function of the connecting pad 26 is to further enhance the connection stability between the damping pad 27 and the inner wall of the upper shell 21, and at the same time, in the process of buffering vibration of the damping pad 27, it plays a role of auxiliary support and stress dispersion, so as to ensure that the damping pad 27 can more effectively play the damping function. The two sides of the upper shell 21 are respectively fixedly connected with the fixed strips 28, and the main function of the fixed strips 28 is to provide an installation and fixing interface for the entire filtering assembly.
[0035] The inner part of the two fixed strips 28 is respectively screwed with a plurality of nuts 29, which can be fastened by passing the bolt through the mounting hole on the fixed strip 28 and using the nut 29. This threaded connection method has the advantages of convenient installation and convenient disassembly, which facilitates operation during equipment maintenance, filter screen replacement or adjustment of the position of the filtering assembly. The front inner wall of the upper shell 21 is fixedly connected with the output pipeline 31, and the main function of the output pipeline 31 is to guide the purified ink filtered through the filter screen inside the upper shell 21 to the ink storage bin 36. The bottom end of the output pipeline 31 is fixedly connected with the ink storage bin 36.
[0036] Example three
[0037] As Figures 1 to 3 , the fixed assembly includes a plurality of push blocks 13, and the top ends of the plurality of push blocks 13 are respectively fixedly connected to the bottom ends of the plurality of springs 12. When the pressure is removed, the spring 12 stretches upward by virtue of its elastic restoring force, thereby driving the push block 13 connected thereto to move upward. The main function of the push block 13 is to convert the elastic force of the spring 12 into a pushing force on the moving block 14. The proximal side bottom ends of the plurality of push blocks 13 are respectively slidably connected with the moving block 14. When the push block 13 moves upward, it pushes the moving block 14 to slide to the distal side, thereby adjusting the position of the limiting ring 15 and providing a key power transmission link for quickly separating or fixing the limiting ring 15 to the fixing of the connecting port 20, thereby ensuring the flexibility and accuracy of the operation of the fixed assembly. The proximal side of the plurality of moving blocks 14 is fixedly connected with the limiting ring 15, and when the moving block 14 slides under the action of the push block 13, it drives the limiting ring 15 to move synchronously. The main function of the limiting ring 15 is to be tightly fixed to the inner wall of the connecting port 20 during normal operation of the device, thereby playing a sealing and fixing role. The bottom ends of the plurality of moving blocks 14 are respectively fixedly connected with the connecting column 16, and when the moving block 14 moves, the connecting column 16 moves synchronously.
[0038] The main function of the connecting column two 16 is to transmit the movement of the moving block 14 to the contraction column three 17, and at the same time, it plays a connecting and supporting role in the entire fixed assembly, ensuring the coordinated movement between the components and enhancing the stability of the structure of the fixed assembly. The outer part of the far side of the plurality of connecting column two 16 is fixedly connected with the contraction column three 17 respectively. When the connecting column two 16 drives the contraction column three 17 to move, the contraction column three 17 can deform according to the external force. During the working process of the fixed assembly, the contraction column three 17 mainly plays a buffering and adjusting role. The outer part of the plurality of contraction column three 17 is sleeved with the spring two 18. When the contraction column three 17 moves under the driving of the connecting column two 16, the spring two 18 will be stretched accordingly. When the contraction column three 17 is subjected to an outward pulling force, the spring two 18 is stretched to store elastic potential energy. The far end of the plurality of connecting column one 9 is fixedly connected with the slip ring 19. When the moving ring 8 slides inside the shell 4, it will drive the slip ring 19 to slide synchronously outside the shell 4 through the connecting column one 9. The main function of the slip ring 19 is to play a connecting and transmitting role during the movement of the internal structure of the device. The bottom end inner wall of the shell 4 is fixedly connected with the connecting port 20. The connecting port 20 mainly plays a connecting and sealing role in the device. Under normal working conditions, the limiting ring 15 is tightly fixed to the inner wall of the connecting port 20, ensuring that the internal materials will not leak during the transmission or processing process, and ensuring the safety and stability of the device. The top end inner wall of the shell 4 is fixedly connected with the input pipeline 30.
[0039] The ink in the ink storage bin two 37 is introduced into the inside of the shell 4 to provide raw materials for the working of the device. The bottom end of the template 1 is fixedly connected with a plurality of lifting columns 32, which usually integrate hydraulic or electric drive systems inside, capable of realizing precise lifting control. The main function of the lifting column 32 is to adjust the height of the template 1 according to the working requirements of the device. The bottom end of the two lifting columns 32 is fixedly connected with the support plate 33. The main function of the support plate 33 is to provide a stable support base for the lifting column 32, and at the same time, evenly distribute the force transmitted by the lifting column 32 to the bearing column 34 below. The bottom end of the two support plates 33 is fixedly connected with two bearing columns 34 respectively. The main function of the bearing column 34 is to bear the weight of the entire device and transmit it to the ground or other support structure. The side close to the two support plates 33 is fixedly connected with the transmission belt 35. The bottom end of the input pipeline 30 is fixedly connected with the ink storage bin two 37. The bottom end of the plurality of limiting blocks 6 is fixedly connected to the top end of the slip ring 19, ensuring the movement synchronization between the limiting block 6 and the slip ring 19, so that the limiting block 6 can accurately limit and guide the movement of the moving ring 8 and related structures according to the movement state of the moving ring 8. The side close to the plurality of contraction column one 7 is fixedly connected to the inner wall of the shell 4.
[0040] The impact force generated by the movement of the limiting block 6 is absorbed, avoiding damage to the internal structure of the device caused by rigid collision. At the same time, the fixed connection between the retractable column one 7 and the inner wall of the shell 4 ensures that the retractable column one 7 can stably play a buffering and adjusting role during the movement of the limiting block 6. The external fixed connection of the limiting ring 15 to the inner wall of the connecting port 20 is driven by the moving block 14 to move the limiting ring 15, which can realize the quick separation of the limiting ring 15 and the connecting port 20, meet the operation requirements of the device, and improve the efficiency of equipment maintenance and component replacement. The external sliding connection of multiple spring two 18 to the inner wall of the shell 4 avoids the twisting or deviation of the spring two 18, ensuring its normal work. During the sliding process of the spring two 18, the interaction with the inner wall of the shell 4 further stabilizes the motion state of the spring two 18. The external sliding connection of multiple spring one 12 to the inner wall of the shell 4.
[0041] When the spring one 12 is stretched and contracted by the pressure transmitted by the lower pressing column 10 and the retractable column two 11, the guiding structure of the inner wall of the shell 4 can ensure that the spring one 12 moves in the correct direction, avoiding deformation or deviation of the spring one 12 during movement. The bottom end of the large filter screen 23 is externally fixed to the rear end inner wall of the lower shell 22, and the bottom end of the large filter screen 23 is tightly connected with the lower shell 22, ensuring that the filtered ink can flow smoothly into the lower shell 22, while preventing ink leakage from the connection between the filter screen and the lower shell 22, ensuring the continuity and sealing of the filtering process. The bottom end of the medium filter screen 24 is externally fixed to the rear end inner wall of the lower shell 22. After intercepting the smaller size impurities that the larger filter screen cannot filter out, the bottom end of the medium filter screen 24 is tightly connected with the lower shell 22, so that the ink filtered by the medium filter screen 24 can flow smoothly into the lower shell 22, further ensuring the smooth progress of the ink filtering process, preventing ink leakage, and also providing stable input conditions for the fine filtering of the small filter screen 25. The bottom end of the small filter screen 25 is externally fixed to the rear end inner wall of the lower shell 22.
[0042] The bottom end of the damping pad 27 is externally fixed to the front inner wall of the lower shell 22, ensuring that the damping pad 27 can stably play a damping role, preventing the damping pad 27 from falling off or being damaged due to uneven stress during long-term use, providing continuous and reliable damping protection for the filter screen, prolonging the service life of the filter screen, and externally fixing the bottom end of the connecting pad 26.
[0043] Working steps
[0044] Step one, when the need to quickly separate the limit ring 15 to the fixed connection port 20, push the control column 5, control column 5 with the limit block 6 in the shell 4 inner wall sliding, limit block 6 movement with retractable column 7 and stretch, while the limit block 6 release slip ring 19 to slide down. Slip ring 19 with the connection column 9 movement, connection column 9 pull the moving ring 8 down slide. Moving ring 8 with the lower column 10 down, the lower column 10 push retractable column 11 and the spring 1 2 outside the set, spring 1 2 compression push block 13 down. Push block 13 of the moving block 14 with the sliding connection to the far side of the slide, the moving block 14 with the limit ring 15 from the inner wall of the connection port 20, in the process, the moving block 14 through the connection column 16 with retractable column 3 17 and the spring 2 18 outside the set movement. Thus realize the quick separation limit ring to the fixed connection port effect, facilitate subsequent to the related parts replacement, cleaning or maintenance operation, improve work efficiency.
[0045] Step two, when the waste ink flows into the upper shell 21, under the action of gravity, the ink drive the impurities downward. First, the large filter screen 23 intercepts larger particles of impurities, preventing them from continuing to descend with the ink. Subsequently, the ink after preliminary filtration drive smaller particles of impurities impact the medium filter screen 24, the medium filter screen 24 further intercepts impurities. Then, the remaining ink and even smaller particles of impurities reach the small filter screen 25, the small filter screen 25 performs fine filtering. In the whole process, the impact of the ink on the filter screen drives the damping pad 27 and the connecting pad 26 to produce a small deformation, which plays a buffering role, reduces the vibration of the filter screen caused by impact, and prolongs the service life of the filter screen. After three levels of filter screen layer by layer filtering, the pure ink flows into the lower shell 22, and enters the ink storage bin 1 36 through the output pipeline 31, thereby realizing the effect of preventing impurities in the waste ink from blocking the pipeline, ensuring the smooth operation of the ink processing system, and avoiding equipment failure or affecting the subsequent process due to pipeline blockage.
[0046] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application.
