Description

Technical Field

[0001] This utility model relates to the field of waste ink recycling and treatment technology in the printing industry, and in particular to a green printing waste ink recycling device. Background Technology

[0002] With the increasing development of the printing industry, a large amount of waste ink is generated every year. Traditional landfill or incineration methods not only pollute the soil, water and air, but also lead to the waste of resources such as pigments and resins. Although the industry has tried to regenerate ink by means of physical sedimentation and chemical demulsification, they generally face bottlenecks such as low separation efficiency, high energy consumption and unstable regeneration quality. With increasingly stringent environmental regulations such as the "Emission Standard for Volatile Organic Compounds in Printing Industry", the development of efficient and energy-saving ink recycling technology has become an urgent need for the industry. As a result, a green waste ink recycling device for printing has emerged. The green printing waste ink recycling device achieves ink regeneration based on the core logic of "pretreatment-component regulation-quality stabilization". First, after the waste ink enters the device, it is filtered to remove large particles such as paper scraps and ink skins, as well as fine impurities such as pigment agglomerates. For emulsified inks, chemical demulsification and centrifugal separation are used to achieve three-phase separation of oil, water and solid. Next, online sensors monitor key parameters such as viscosity and color of the ink in real time. According to preset standards, diluents, pigments and other ingredients are automatically added for precise compounding. At the same time, a temperature control system maintains a suitable temperature to ensure that the ink composition meets the requirements of the printing process. Finally, vacuum degassing is performed to eliminate bubbles and volatile substances. After quality inspection, qualified ink is transported to storage tanks or printing presses, while unqualified ink is returned for reprocessing, achieving efficient recycling of waste ink. Current green printing waste ink recycling devices have a significant role in promoting resource recycling and environmental transformation in the industry. However, they still face key challenges in practical applications. The high viscosity of the ink itself can cause filter plate pore blockage during the filtration process. Viscous ink has poor fluidity, and impurities such as fine pigment particles and dried ink skins easily adhere to the surface of the filter material or embed in the filter pores, forming a dense filter cake layer that hinders ink passage. This not only leads to a significant decrease in filtration efficiency but also requires frequent shutdowns to clean the filter plates, increasing labor maintenance costs and equipment wear. In addition, viscous ink can also stagnate and deposit during pipeline transportation, further affecting the continuity of device operation. Therefore, a green printing waste ink recycling device is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a green printing waste ink recycling device, which aims to improve the problem that the high viscosity of ink itself causes filter plate pore blockage during the filtration process in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A green printing waste ink recycling device includes a housing, a feeding mechanism fixedly connected to the inner wall of the housing, a barrel fixedly connected to the inside of the housing, and a filtering mechanism rotatably connected to the inner wall of the barrel. The filtration mechanism includes a rotating disk, the outer wall of which is rotatably connected to the inner wall of the barrel, a motor fixedly connected to the bottom of the barrel, multiple protrusions fixedly connected to the top of the rotating disk, a filter plate slidably connected to the inner wall of the barrel, multiple sliding columns fixedly connected to the bottom of the filter plate, a rotating column fixedly connected to the top center of the rotating disk, an inclined plate fixedly connected to the inner wall of the barrel, a primary screening component rotatably connected to the outer wall of the rotating column, and a bonding component fixedly connected to the outer wall of the rotating column. Through the above technical solution: the main body of the device is composed of a shell, and the feeding mechanism fixed on its inner wall can realize the orderly introduction of waste ink. The shell contains a barrel, which is the core processing space. The filtration mechanism rotatably connected to the inner wall of the barrel is a key component of the device. In the filtration mechanism, the outer wall of the rotating disk is rotatably connected to the inner wall of the barrel. The bottom is driven by a motor, which can drive the rotating disk to rotate stably. Multiple protrusions on the top of the rotating disk can disturb the ink during rotation, enhancing its flowability. The filter plate interacts with the rotating disk through the sliding column at the bottom. Under the push of the protrusion, it can slide up and down reciprocally, effectively preventing ink from clogging the filter pores. In addition, the rotating column at the center of the top of the rotating disk has a primary screening component connected to its outer wall, which can perform preliminary screening of the ink. The fitting component on the outer wall of the rotating column can closely fit the filter plate on the inner wall of the barrel, assisting the flow and filtration of ink in the barrel, thereby improving the overall filtration efficiency and providing an efficient and stable treatment method for the recycling of waste ink.

[0005] As a further description of the above technical solution: The feeding mechanism includes a support column, the outer wall of which is fixedly connected to the inner wall of the housing, a liquid storage pipe is fixedly connected to one side of the support column, a cylinder is fixedly connected to the inside of the support column, a push plate is fixedly connected to one side of the cylinder, a plug is slidably connected to one side of the inner wall of the liquid storage pipe, and a liquid outlet pipe is fixedly connected to the other side of the inner wall of the liquid storage pipe. The above technical solution utilizes a support column as the basic structure, with its outer wall fixedly connected to the inner wall of the housing to ensure overall stability. A liquid storage tube fixed on one side of the support column is used to temporarily store the filtered ink. An internal cylinder drives a pusher plate to slide laterally via a piston rod. When the cylinder is activated, the pusher plate compresses the air in the liquid storage tube, allowing the ink to escape from the outlet pipe. When the pusher plate is pulled back, the change in pressure causes the plug to disengage from the pipe opening, allowing the ink to enter the liquid storage tube. This structure, through efficient cylinder control, achieves stable delivery and flow regulation of the filtered waste ink, avoiding problems such as poor feeding or dripping caused by ink viscosity, and providing continuous and uniform material input for subsequent processes.

[0006] As a further description of the above technical solution: The primary screening assembly includes a screen plate one, the inner wall of the screen plate one is rotatably connected to the outer wall of the rotating column, a scraper one is fixedly connected to the outer wall of the rotating column, a screen plate two is rotatably connected to the outer wall of the rotating column, and a scraper two is fixedly connected to the outer wall of the rotating column. Through the above technical solution: the primary screening component is equipped with two important screen plates. Screen plate one rotates relative to the outer wall of the rotating column, and screen plate two also rotates relative to the rotating column as the axis. On the outer wall of the rotating column, scraper one corresponds to screen plate one, and scraper two corresponds to screen plate two. The surfaces of screen plate one and screen plate two are covered with fine screen holes, which can intercept large particulate impurities in waste ink.

[0007] As a further description of the above technical solution: The bonding assembly includes a top plate, a bottom plate is slidably connected to the outer wall of the top plate, and three limiting posts are fixedly connected to the inner wall of the bottom plate. The outer walls of the three limiting posts are all fitted with springs. The above technical solution involves a bonding assembly comprising a top plate and a bottom plate, which are arranged vertically in a corresponding manner. Three limiting posts are fixed to the inner wall of the bottom plate, and these posts are evenly arranged in a straight line. Each limiting post has a spring fitted on its outer wall, with the top end of the spring contacting the bottom surface of the top plate and the bottom end fixed to the surface of the bottom plate. In operation, the spring is in a compressed state, providing upward elastic support to the top plate, ensuring a tight fit between the top plate and the inclined plate on the inner wall of the barrel. This assembly utilizes the elastic deformation capability of the spring to ensure that the bonding assembly maintains good contact with the filter plate during rotation, effectively preventing ink from clogging the filter pores during filtration and improving filtration efficiency and separation effect.

[0008] As a further description of the above technical solution: The drive end of the motor is fixedly connected to the bottom of the rotating disk, the bottom of the base plate is slidably connected to the top of the filter plate, and one side of the base plate is slidably connected to the outer wall of the rotating column. The above technical solution enables the rotating disk to rotate after the motor is started. The bottom of the base plate can slide on the top of the filter plate, and one side of it slides against the outer wall of the rotating column. When the rotating disk rotates, the filter plate moves accordingly. The base plate is constrained by the rotating column and slides on the top of the filter plate, so that the bonding component and the filtration mechanism work together to ensure smooth linkage of each component during the filtration and separation of waste ink, thereby improving the overall processing efficiency.

[0009] As a further description of the above technical solution: The bottoms of the plurality of sliding columns are slidably connected to the top of the rotating disk, and the outer walls of the plurality of sliding columns are slidably connected to the inner wall of the inclined plate; Through the above technical solution: when the rotating disk rotates, the sliding column moves back and forth in the vertical direction under the action of the protrusion, which drives the filter plate to vibrate synchronously. This design converts the circular motion of the rotating disk into the linear motion of the filter plate. By utilizing the cooperation of the sliding column and the protrusion, the filter plate is continuously shaken, which effectively avoids viscous ink clogging the filter pores, improves filtration efficiency, and ensures that waste ink maintains good flowability and separation effect during recycling.

[0010] As a further description of the above technical solution: The outer walls of both the first sieve plate and the second sieve plate are fixedly connected to the inner wall of the barrel. The bottom of the second scraper plate is in contact with the top of the second sieve plate, and the bottom of the first scraper plate is in contact with the top of the first sieve plate. With the above technical solution: the outer walls of sieve plate one and sieve plate two are fixed to the inner wall of the barrel and are distributed vertically. Scraper plate two and scraper plate one can scrape sieve plate two and sieve plate one under the action of external force.

[0011] As a further description of the above technical solution: The outer wall of the pusher plate is slidably connected to the inner wall of the support column, and the outer wall of the liquid storage tube is fixedly connected to the inner wall of the housing. Through the above technical solution: the push plate slides inside the support column under the action of external force, so that the air pressure inside the support column and the liquid storage tube can be changed and adjusted, and the outer wall of the liquid storage tube is on the inner wall of the shell, making the whole device more stable.

[0012] This utility model has the following beneficial effects: 1. In this utility model, after the waste ink is poured into the barrel, the bottom motor is started to drive the rotating disk to rotate. The protrusions on the disk rotate along the path. When the sliding column contacts the protrusion, the height difference causes the filter plate to slide up and down, generating vibration. This allows the ink to pass through the filter holes more fully after the initial screening on the sieve plate. When the filter plate vibrates, the spring of the fitting component cooperates with the limiting column to keep the bottom plate always in contact with the top of the filter plate. At the same time, the rotating column drives the bottom plate and scraper to scrape the filter plate and sieve plate respectively, removing the surface ink. This synergistic effect of vibration and scraping effectively solves the problem of high viscosity ink clogging the filter holes, which not only extends the service life of the device, but also improves the recycling efficiency of waste ink and ensures the stability of the recycling process.

[0013] 2. In this utility model, when the waste ink filtered at the top of the inclined plate accumulates to a certain amount, the cylinder inside the support column is activated. The cylinder pulls the pusher plate, which reduces the air pressure inside the support column and the liquid storage tube. The plug slides open under the pressure difference, and the ink flows into the liquid storage tube. Subsequently, the cylinder pushes the pusher plate to move in the opposite direction, which increases the air pressure inside the liquid storage tube. The plug re-seals the tube opening, and ink accumulation resumes at the top of the inclined plate. At the same time, the pusher plate squeezes the liquid storage tube, causing the ink to be discharged from the outlet pipe. This process achieves quantitative ink delivery by precisely controlling the air pressure and the pusher plate action, effectively solving the problems of poor material flow and leakage of viscous ink, providing stable material for subsequent processing, and improving the operating efficiency of the device.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0017] Reference Figures 1 to 3 The present invention provides an embodiment of a green printing waste ink recycling device, comprising a housing 1, a feeding mechanism 2 fixedly connected to the inner wall of the housing 1, and a stable installation space and working environment for the internal mechanisms through the support and protection of the housing 1. A barrel 5 is fixedly connected inside the housing 1, and the barrel 5 serves as the core processing space, carrying the filtration and separation process of waste ink. A filtration mechanism 3 is rotatably connected to the inner wall of the barrel 5. The filtration mechanism 3 can achieve efficient filtration of waste ink through rotation. The filtration mechanism 3 includes a rotating disk 31, the outer wall of which is rotatably connected to the inner wall of the barrel 5. The rotating disk 31 can rotate stably within the barrel 5, providing the power basis for the filtration process. A motor 32 is fixedly connected to the bottom of the barrel 5, serving as the power source. Multiple protrusions 33 are fixedly connected to the top of the rotating disk 31. A filter plate 38 is slidably connected to the inner wall of the barrel 5. The filter plate 38 is the core component of the filtration process. Multiple sliding columns 34 are fixedly connected to the bottom of the filter plate 38. The sliding columns 34 cooperate with the protrusions 33 to convert the rotational motion of the rotating disk 31 into... The filter plate 38 vibrates up and down. A rotating column 35 is fixedly connected to the top center of the rotating disk 31. The rotating column 35 connects the primary screening assembly 36 and the bonding assembly 37 and transmits rotational power. An inclined plate 4 is fixedly connected to the inner wall of the barrel 5. The inclined plate 4 can guide the filtered ink to flow in a specified direction for easy subsequent collection and processing. The primary screening assembly 36 is rotatably connected to the outer wall of the rotating column 35. The primary screening assembly 36 can perform preliminary screening of waste ink and separate large particle impurities. The bonding assembly 37 is fixedly connected to the outer wall of the rotating column 35. The bonding assembly 37 is kept in contact with the filter plate 38 through elastic support, which assists filtration and prevents clogging. The feeding mechanism 2 includes a support column 21. The outer wall of the support column 21 is fixedly connected to the inner wall of the housing 1, providing structural support for the feeding mechanism 2 and ensuring its stable operation. A liquid storage pipe 22 is fixedly connected to one side of the support column 21. The liquid storage pipe 22 is used to temporarily store the filtered ink for subsequent quantitative delivery. A cylinder 23 is fixedly connected inside the support column 21. A push plate 24 is fixedly connected to one side of the cylinder 23. The push plate 24 can slide inside the support column 21 under the action of the cylinder 23. By changing the pressure in the liquid storage pipe 22, the feeding and stopping of the ink is controlled. A plug 25 is slidably connected to one inner wall of the liquid storage pipe 22. The plug 25 can automatically open or close the pipe opening under pressure changes to realize quantitative delivery of ink. An outlet pipe 26 is fixedly connected to the other inner wall of the liquid storage pipe 22. The outlet pipe 26 is used to transport the ink in the liquid storage pipe 22 to the subsequent processing stage to ensure continuous output of materials.

[0018] Specifically, the green printing waste ink recycling device consists of a shell, a feeding mechanism, and a barrel. The shell provides a stable working space, while the barrel serves as the core processing area, containing a motor-driven filtration mechanism. This mechanism uses a rotating disc, protrusions, and sliding columns to convert rotational motion into filter plate vibration. This, along with the primary screening component and the bonding component, completes efficient ink filtration and prevents clogging. The feeding mechanism uses support columns, cylinders, and pushers to change the pressure of the liquid storage pipe and control the opening and closing of the plugs. This enables the temporary storage, quantitative delivery, and continuous output of the filtered ink, solving the feeding problem caused by the viscosity of the ink and ensuring the efficient operation of the device.

[0019] Reference Figures 2 to 4 The primary screening component 36 includes a first screen plate 361, the inner wall of which is rotatably connected to the outer wall of the rotating column 35. When the first screen plate 361 rotates with the rotating column 35, it can perform the first layer of screening of ink and intercept larger particle impurities. A scraper 362 is fixedly connected to the outer wall of the rotating column 35. The scraper 362 is close to the top of the first screen plate 361 and can scrape off the ink adhering to the surface of the first screen plate 361 when rotating with the rotating column 35 to prevent the screen holes from clogging. A second screen plate 363 is rotatably connected to the outer wall of the rotating column 35. The second screen plate 363 and the first screen plate 361 form a multi-stage screening to further separate smaller particle impurities and improve the primary screening effect. A second scraper 364 is fixedly connected to the outer wall of the rotating column 35. The scraper 364 is close to the top of the second screen plate 363 and ensures the screening efficiency of the second screen plate 363 by rotating and scraping. The bonding assembly 37 includes a top plate 371, with a bottom plate 372 slidably connected to the outer wall of the top plate 371. The top plate 371 and bottom plate 372 maintain contact during filter plate 38 vibration through sliding engagement, while also accommodating certain displacement changes. Three limiting posts 373 are fixedly connected to the inner wall of the bottom plate 372. These limiting posts 373 limit the sliding range of the top plate 371, ensuring the stability of the bonding assembly 37. Springs 374 are fitted onto the outer walls of each of the three limiting posts 373. The springs 374 use elastic force to keep the top plate 371 tightly against the inner wall of the inclined plate 4, while also buffering the impact force from the vibration of the filter plate 38, ensuring a good bonding effect. The drive end of the motor 32 is fixedly connected to the bottom of the rotating disk 31. The driving force of the motor 32 can be directly and stably transmitted to the rotating disk 31 to ensure the power supply of the filter mechanism 3. The bottom of the base plate 372 is slidably connected to the top of the filter plate 38. When the base plate 372 vibrates with the filter plate 38, it can always maintain contact with the filter plate 38 through the elastic action of the bonding component 37 to assist the filtration process. One side of the base plate 372 is slidably connected to the outer wall of the rotating column 35. The rotation of the rotating column 35 can drive the base plate 372 to rotate synchronously, realizing the coordinated action of the bonding component 37 and the filter mechanism 3. The bottom of the sliding column 34 is slidably connected to the top of the rotating disk 31. The sliding column 34 can slide on the top of the rotating disk 31 with the rotation of the protrusion 33, generating vertical displacement. The outer walls of multiple sliding columns 34 are slidably connected to the inner wall of the inclined plate 4. The inclined inner wall of the inclined plate 4 provides guidance for the sliding columns 34, converting the sliding of the sliding columns 34 into the up-and-down vibration of the filter plate 38, thus enhancing the filtration effect. The outer walls of screen plate one 361 and screen plate two 363 are fixedly connected to the inner wall of the barrel 5. Screen plate one 361 and screen plate two 363 are fixedly installed to form a stable sieve layer, ensuring that the ink passes through each layer of screen plates in sequence. The bottom of scraper two 364 is in contact with the top of screen plate two 363, and the bottom of scraper one 362 is in contact with the top of screen plate one 361. Scraper one 362 and scraper two 364 continuously clean the screen plates by rotating and scraping. On the surface, the problem of screen clogging caused by ink viscosity is greatly reduced, the service life of the device is extended and the recycling efficiency is improved. The outer wall of the pusher plate 24 is slidably connected to the inner wall of the support column 21. The pusher plate 24 can slide smoothly in the support column 21. By changing the pressure in the liquid storage tube 22, the feeding rhythm of the ink is precisely controlled. The outer wall of the liquid storage tube 22 is fixedly connected to the inner wall of the housing 1. The fixed installation of the liquid storage tube 22 ensures the matching accuracy between it and other parts of the feeding mechanism 2, realizes the stable pushing and flow regulation of the filtered ink, avoids the problem of poor feeding and dripping, provides continuous and uniform material input for subsequent operations, and greatly improves the overall operating efficiency of the device.

[0020] Specifically, the primary screening component and the bonding component of the device work together to ensure efficient filtration and stable delivery of waste ink. The primary screening component intercepts impurities of various sizes through multi-stage screening using screen plate one and screen plate two, and scrapes the ink off the surface of the screen plates with scraper plate one and scraper plate two to prevent screen clogging. The bonding component relies on the sliding cooperation of the top plate and bottom plate, combined with the limiting column and spring, to ensure that the filter plate remains in contact when it vibrates and to buffer the impact force. The motor powers the filtration mechanism, and the inclined plate guides the sliding column to vibrate the filter plate, enhancing the filtration effect. In the feeding mechanism, the pusher slides in the support column to change the pressure of the liquid storage tube, precisely control the opening and closing of the plug, realize quantitative delivery of ink, and improve the overall operating efficiency of the device.

[0021] Working principle: Waste ink is poured in from the top of barrel 5, so that the waste ink first contacts the second sieve plate 363. At this time, the motor 32 located at the bottom of barrel 5 is started, so that the driving force of the motor 32 drives the rotating disk 31 to rotate, so that multiple protrusions 33 perform periodic circular motion along a predetermined circumferential path. Multiple sliding columns 34 are exactly located on the predetermined circumferential path. When the sliding columns 34 slide and contact the protrusions 33 on the top of the rotating disk 31, a height difference is generated, so that the sliding columns 34 drive the filter plate 38 to slide up and down on the inner wall of barrel 5, thereby achieving the vibration effect of the filter plate 38, so that the ink passing through the second sieve plate 363 and the first sieve plate 363 can be filtered. The waste ink after screening is filtered more thoroughly. Due to the cooperation between the limiting column 373 and the spring 374, the bottom of the base plate 372 can always be in contact with the top of the filter plate 38 during the vibration of the sliding column 34. Due to the transmission of the rotating column 35, the base plate 372, scraper 1 362 and scraper 2 364 can scrape the top of the filter plate 38 and the top of the screen plate 1 361 and screen plate 2 363 respectively. This greatly reduces the problem of filter plate 38 pore blockage caused by the high viscosity of the ink itself during the filtration process, thereby greatly extending the service life of the entire device and greatly improving the recycling efficiency. When the filtered waste ink accumulates to a certain amount at the top of the inclined plate 4, the cylinder 23 located inside the support column 21 is activated, causing the cylinder 23 to pull back the push plate 24. This changes the pressure in the cavity inside the support column 21 and the liquid storage tube 22, causing the plug 25 to slide off at the tube opening. This allows the filtered waste ink on the surface of the inclined plate 4 to enter the liquid storage tube 22. The push plate 24 then acts in the opposite direction, again changing the pressure in the cavity inside the support column 21 and the liquid storage tube 22. This causes the plug 25 to slide and block the tube opening of the liquid storage tube 22, causing the waste ink at the top of the inclined plate 4 to accumulate again. The reverse action of the push plate 24 allows the filtered waste ink inside the liquid storage tube 22 to exit the device through the outlet pipe 26. This ensures stable delivery and flow regulation of the filtered waste ink, avoiding problems such as poor material feeding and leakage caused by ink viscosity. It provides continuous and uniform material input for subsequent operations, significantly improving the overall operating efficiency of the device.
