[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1-4 This application provides an environmentally friendly decorative paper ink recycling and reuse device, comprising: The peeling mechanism has openings 1 at both ends for the decorative paper 2 to enter and exit, and an ultrasonic peeling component is installed inside. The ultrasonic peeling component contains a peeling liquid for immersing the decorative paper 2, and the ultrasonic peeling component is used to peel the waste ink on the decorative paper 2 into the peeling liquid. Waste ink collection box 3, which is connected to the ultrasonic stripping assembly, is used to receive stripping liquid mixed with waste ink; Centrifugal separation mechanism 4 is connected to the waste ink collection box 3. The centrifugal separation mechanism 4 is used to separate waste ink from stripping liquid, and discharge waste ink from waste ink outlet 5 and stripping liquid from stripping liquid outlet 6. A multi-stage filtration component 7 is connected to the waste ink outlet 5 and is used to perform multi-stage filtration on waste ink.

[0021] Specifically, the environmentally friendly decorative paper ink recycling and reuse device provided in this application comprises four core parts that work together to complete the waste ink recycling and reuse process. The stripping mechanism 1, as the primary step in waste ink stripping, has openings 11 at both ends for decorative paper to enter and exit. The decorative paper enters the mechanism through one opening 11, is processed, and then exits through the other opening 11. The stripping mechanism 1 contains an ultrasonic stripping component 2, which is pre-filled with sufficient stripping liquid. When the decorative paper enters the stripping mechanism 1, it is completely immersed in the stripping liquid. The ultrasonic stripping component 2 then activates, using the energy of ultrasound to effectively strip the waste ink adhering to the surface of the decorative paper, mixing the waste ink into the stripping liquid. Connected to the ultrasonic stripping component 2 is a waste ink collection tank 3, whose main function is to receive the stripping liquid mixed with waste ink discharged from the ultrasonic stripping component 2, providing centralized collection for subsequent processing. The waste ink collection box 3 is subsequently connected to a centrifugal separation mechanism 4. After the mixed liquid enters this mechanism through the connecting channel, the centrifugal separation mechanism 4 uses centrifugal force to process the mixed liquid, separating the waste ink from the stripping liquid. A transfer pump 36 is installed on the connecting channel to assist in the transfer of the stripping liquid containing waste ink. After separation, the waste ink is discharged from the specially designed waste ink outlet 5, while the stripping liquid is discharged from the corresponding stripping liquid outlet 6, achieving the initial separation of the two. Finally, the waste ink discharged from the waste ink outlet 5 enters the multi-stage filtration component 7 connected to it. This component purifies the waste ink through multiple filtration processes, removing impurities contained in the waste ink, thereby obtaining reusable ink and completing the entire recycling and reuse process.

[0022] Furthermore, the stripping mechanism includes a device housing 8, the inside of which is provided with an installation space for accommodating the ultrasonic stripping assembly, and the top of the device housing 8 is provided with a detachable top cover 9; two openings 1 are respectively provided at both ends of the device housing 8 and communicate with the installation space, and at both ends of the device housing 8, corresponding to the positions of the two openings 1, an unwinding device 10 and a winding device 11 are respectively provided.

[0023] Specifically, the outer shell 8 of the peeling mechanism has a rectangular structure, forming an internal installation space that can perfectly accommodate the ultrasonic peeling component, ensuring that the ultrasonic peeling component is not interfered with due to space limitations during operation. The top of the outer shell 8 is provided with a removable top cover 9, which is tightly connected to the outer shell 8 by multiple evenly distributed fastening bolts. The edge of the top cover 9 is also equipped with an elastic sealing gasket. This design not only allows the top cover 9 to be easily removed, facilitating the staff to perform regular inspections, maintenance, and replacement of parts for the ultrasonic peeling component inside the outer shell (8), but also effectively prevents the peeling fluid from overflowing from the top of the outer shell 8 due to splashing during the ultrasonic peeling process.

[0024] Two openings 1 are respectively opened on the side walls at both ends of the device housing 8 along the length direction. The height and width of the openings 1 match the size of the decorative paper 2 to be processed, ensuring that the decorative paper 2 can smoothly enter and exit the device housing 8 through the openings 1. The openings 1 are connected to the installation space inside the device housing 8, providing a channel for the decorative paper 2 to enter the ultrasonic stripping assembly.

[0025] At the two openings 1 at both ends of the device housing 8, an unwinding device 10 and a winding device 11 are respectively installed. The unwinding device 10 includes a sturdy support with an unwinding shaft rotatably mounted on it. The unwinding shaft is connected to a drive motor. The roll of decorative paper 2 to be processed is placed on the unwinding shaft. The drive motor drives the unwinding shaft to rotate at a preset speed, thus smoothly releasing the decorative paper 2 and allowing it to enter the ultrasonic peeling assembly inside the device housing 8 through the corresponding opening 1. The winding device 11 also includes a sturdy support with a winding shaft rotatably mounted on it. The winding shaft is also connected to a corresponding drive motor. After ultrasonic peeling, the decorative paper 2 passes through another opening 1 and is guided onto the winding shaft. Driven by the drive motor, the winding shaft rotates at a speed matching that of the unwinding device 10, neatly winding up the processed decorative paper 2. This achieves continuous conveying and processing of the decorative paper 2, greatly improving the efficiency of waste ink recycling and meeting the needs of large-scale production.

[0026] Furthermore, the ultrasonic ablation assembly includes: A stripping liquid tank 12 is provided to contain stripping liquid. An ultrasonic generator 13 and a drain outlet are provided at the bottom of the stripping liquid tank 12. The drain outlet is connected to the waste ink collection box 3. A support roller 14 is provided between the stripping liquid tank 12 and each of the two openings 1. Two sets of guide rollers 15 are disposed inside the peeling liquid tank 12, and a gap is formed between each set of guide rollers 15 for the decorative paper 2 to pass through. The guide rollers 15 are used to immerse the decorative paper 2 in the peeling liquid. A paper pressing assembly is disposed between the two sets of guide rollers 15, and the paper pressing assembly is used to press down the decorative paper 2.

[0027] Specifically, the ultrasonic stripping component's stripping liquid tank 12 has a rectangular structure. Its internal size is designed according to the width and processing volume of the decorative paper 2, ensuring sufficient stripping liquid to completely immerse the decorative paper 2 during passage. An ultrasonic generator 13 installed at the bottom of the stripping liquid tank 12 generates high-frequency ultrasonic vibrations, which are applied to the stripping liquid to efficiently strip the waste ink from the surface of the decorative paper 2. A drain outlet at the bottom of the stripping liquid tank 12 connects to the waste ink collection tank 3 via a corrosion-resistant pipe. A flow control valve is installed on the pipe to adjust the draining speed according to the amount of waste ink mixed in the stripping liquid, ensuring a stable flow of the mixed liquid into the waste ink collection tank 3.

[0028] Support rollers 14 are provided between the peeling liquid tank 12 and the two openings 1. The two ends of the rollers are fixed to the inner wall of the device housing 8 by bearing seats. The height of the support rollers 14 is adapted to the bottom edge of the openings 1, which can provide stable support for the decorative paper 2 entering and leaving the peeling liquid tank 12, and prevent the decorative paper 2 from deviating from the conveying path due to its own weight.

[0029] Both sets of guide rollers 15 are installed inside the stripping liquid tank 12. Each set of guide rollers 15 consists of two rollers arranged vertically in parallel. The distance between the two sets of guide rollers 15 is adjusted according to the thickness of the decorative paper 2, allowing the decorative paper 2 to pass through the gap between the two sets of guide rollers 15. The installation height of the guide rollers 15 is lower than the liquid level of the stripping liquid, thereby completely immersing the decorative paper 2 in the stripping liquid. This ensures that the ultrasonic waves can act evenly on all areas of the surface of the decorative paper 2, improving the waste ink stripping effect.

[0030] The paper pressing assembly is used to press down the decorative paper between the two sets of guide rollers 15 to ensure that it is completely immersed in the stripping liquid.

[0031] Furthermore, the paper pressing assembly includes: Movable plate 16, which is slidably installed on the inner wall of the stripping liquid tank 12, with the sliding direction perpendicular to the bottom surface of the stripping liquid tank 12; Multiple pressure rollers 17 are rotatably mounted on the movable plate 16.

[0032] Specifically, the side of the movable plate 16 slides into a groove on the inner wall of the stripping liquid tank 12, with the sliding direction perpendicular to the bottom surface of the stripping liquid tank 12. The movable plate 16 can be controlled to move up and down by a cylinder or spring mechanism, which can accommodate decorative paper 2 of different thicknesses and adjust the depth of the decorative paper immersed in the stripping liquid. Multiple pressure rollers 17 are evenly distributed on the movable plate 16. The pressure rollers 17 are connected to the movable plate 16 through bearings and can rotate freely. The bottom surface of the pressure rollers 17 is in contact with the upper surface of the decorative paper 2. Under the pressure of the movable plate 16, the decorative paper 2 is pressed tightly against the bottom of the stripping liquid tank 12, preventing the decorative paper 2 from wrinkling or floating in the stripping liquid due to ultrasonic vibration, ensuring that the surface of the decorative paper 2 is in full contact with the stripping liquid, and further improving the waste ink stripping efficiency.

[0033] Furthermore, the peeling liquid tank 12 is provided with a first scraper 18 at the end near the decorative paper 2, and the first scraper 18 is located above the decorative paper 2.

[0034] Specifically, the first scraper 18, located near the end of the peeling liquid tank 12 away from the decorative paper 2, is made of rubber with suitable hardness and a certain degree of elasticity. It has a long, strip-like structure, with its length matching the width of the decorative paper 2 to ensure complete coverage of its width. The first scraper 18 is fixedly mounted on the inner wall of the peeling liquid tank 12 via a bracket. During the conveying process of the decorative paper 2, as it moves, the first scraper 18 continuously scrapes its surface, further removing residual waste ink and peeling liquid. The scraped-off waste ink and peeling liquid flow back into the peeling liquid tank 12 along the scraper's angle, achieving recycling and reuse of the peeling liquid and reducing resource waste. Simultaneously, by removing excess peeling liquid, it also prevents the decorative paper 2 from becoming damp or sticky when entering the winding device 11, ensuring that the wound decorative paper 2 remains dry and flat after winding, facilitating subsequent processing or storage.

[0035] Furthermore, the multi-stage filtering component 7 includes: The filter chamber 19 has a filter channel 20 inside, and the side wall of the filter channel 20 is inclined. The top of the filter chamber 19 has an ink inlet 21 that connects the waste ink outlet 5 and the filter channel 20, and the bottom has an ink outlet 22 that connects the filter channel 20 to the outside. The three filter plates 23 are arranged vertically, and the filtration accuracy of the three filter plates 23 increases from top to bottom; the filter plates 23 are inserted into the filter channel 20 from one side of the filter chamber 19.

[0036] Specifically, the filter chamber 19 has a closed cavity structure, and a filter channel 20 is formed inside it. The side wall of the channel is inclined, which can ensure that the waste ink flows smoothly in the channel by its own gravity, and can also extend the residence time of the waste ink in the filter channel 20 to ensure thorough filtration.

[0037] The ink inlet 21 at the top of the filter chamber 19 is connected to the waste ink outlet 5 of the centrifugal separation mechanism 4 via a pipe. A flow regulating valve is installed on the pipe, which can flexibly control the flow rate of waste ink entering the filter channel 20 according to the amount of waste ink being transported, avoiding incomplete filtration due to excessive flow. The ink outlet 22 at the bottom of the filter chamber 19 is connected to an external ink collection device. The pure ink after multi-stage filtration is discharged through the ink outlet 22, realizing recycling and reuse.

[0038] Three filter plates 23 are arranged vertically within the filter channel 20, with the pore diameter of the filter plates 23 gradually decreasing from top to bottom, meaning the filtration precision increases sequentially. The upper filter plate 23 is mainly used to filter larger particles of impurities in waste ink, the middle filter plate 23 further filters medium-sized impurities, and the lower filter plate 23 filters fine impurities. Through this three-layer, step-by-step filtration, the purification effect of waste ink can be significantly improved.

[0039] The filter plate 23 adopts a plug-in design, which is inserted into the filter channel 20 from the slot on one side of the filter chamber 19. After insertion, it fits tightly against the inner wall of the filter channel 20, ensuring that all waste ink can pass through the filter plate 23 without leakage from the gaps. This design makes the filter plate 23 extremely easy to install and remove. When a lot of impurities accumulate on the surface of the filter plate 23 and affect the filtration efficiency, the staff can easily pull it out for cleaning or replacement, ensuring the continuous and efficient operation of the multi-stage filtration assembly 7.

[0040] Furthermore, a second scraper 24 is provided above each filter plate 23 in the filter channel 20, and the bottom end of the second scraper 24 abuts against the top surface of the filter plate 23; the second scraper 24 is slidably installed on the side wall of the filter chamber 19, and the sliding direction is parallel to the top surface of the filter plate 23.

[0041] Specifically, a second scraper 24 is provided above each filter plate 23 within the filter channel 20. This scraper is elongated, with its length matching the width of the filter plate 23, completely covering the top surface width of the filter plate 23. The bottom end of the second scraper 24 abuts tightly against the top surface of the filter plate 23. The abutting force is precisely controlled by the installation structure, ensuring effective removal of impurities accumulated on the surface of the filter plate 23 without damaging the filter media. The sides of the second scraper 24 are tightly fitted to the side walls of the filter chamber 19 and can slide relative to each other. The sliding drive can be achieved by a motor-driven screw drive or a cylinder-driven mechanism, allowing the second scraper 24 to move above the filter plate 23 at a set frequency and speed.

[0042] When impurities gradually accumulate on the surface of the filter plate 23 during the filtration process, affecting the flow rate of waste ink, the second scraper 24 slides along the slide rail under the action of the drive device 33, and the bottom edge of the scraper is in close contact with the top surface of the filter plate 23 to scrape the attached impurities to one side of the filter plate 23, so as to avoid the impurities from being mixed into the waste ink again and to ensure the long-term stability of the filtration efficiency of the filter plate 23.

[0043] Furthermore, it also includes a waste ink collection mechanism 25, which is located below the printing press and connected to the waste ink collection box 3, and is used to collect waste ink generated during the cleaning of the printing press.

[0044] Specifically, the waste ink collection mechanism 25 is precisely positioned directly below the printing press, with its top opening corresponding to the waste liquid discharge area of ​​the printing press's cleaning process. This ensures that waste ink and cleaning fluid generated during routine cleaning of the printing press can be completely collected, preventing waste ink from dripping onto the ground and causing pollution or resource waste. This design allows for the recycling of not only waste ink on rolls of decorative paper 2 but also waste ink generated during printing press cleaning, avoiding the environmental pollution and resource waste caused by direct discharge in the past. Furthermore, its connection to the waste ink collection box 3 enables centralized processing of various types of waste ink, simplifying the recycling process.

[0045] Furthermore, the waste ink collection mechanism 25 includes: The receiving groove 26 has an opening 1 at the top, and the size of the top end is larger than the size of the bottom end; The ink guiding channel 27 connects the bottom end of the receiving groove 26 and the waste ink collection box 3; one end of the ink guiding channel 27 connected to the waste ink collection box 3 is provided with a filter screen 28, and the bottom is provided with an openable and closable waste discharge port 29.

[0046] Specifically, the receiving trough 26 of the waste ink collection mechanism 25 has an overall funnel-shaped structure. The size of the top opening 1 is designed according to the range of the printing press cleaning area to ensure that it can fully collect the waste ink and cleaning fluid dripping during the cleaning process and avoid pollution caused by missed collection. The bottom end of the receiving trough 26 is connected to the waste ink collection box 3 through the ink guiding channel 27. A filter screen 28 is embedded in the end of the ink guiding channel 27 near the waste ink collection box 3, which can initially filter out larger impurities such as paper fragments and fibers mixed in with the waste ink and prevent them from entering the waste ink collection box 3 and affecting subsequent processing. The bottom of the ink guiding channel 27 is provided with an openable and closable waste discharge port 29. When the filter screen 28 traps too many impurities or the ink guiding channel 27 becomes blocked, the waste discharge port 29 can be opened to discharge the accumulated impurities and clean the channel, ensuring the smooth flow of the ink guiding channel 27.

[0047] Furthermore, the waste ink collection mechanism 25 also includes a cleaning component, which includes: Positioning shell 30 is detachably installed on the outer wall of the ink guiding channel 27. The positioning shell 30 is provided with a transmission screw 31 and a sliding block 32. The sliding block 32 is slidably connected to the inner wall of the positioning shell 30 and threadedly connected to the transmission screw 31. A driving device 33 is installed at one end of the transmission screw 31. The cleaning scraper 34 has its bottom surface attached to the bottom surface of the ink guiding channel 27, and its top surface is arc-shaped and fixed to the sliding block 32 by a connecting rod 35.

[0048] Specifically, the shape of the positioning housing 30 is adapted to the outer wall contour of the ink guiding channel 27, and it is detachably installed on the outer wall of the ink guiding channel 27 by means of a snap-fit ​​or bolt assembly, and fits tightly with the ink guiding channel 27 after installation. The positioning housing 30 has reserved space inside to accommodate the transmission lead screw 31 and the sliding block 32.

[0049] The transmission screw 31 is fixed to the inner wall of the positioning housing 30 at both ends by bearing seats, and its axis is parallel to the length direction of the ink guiding channel 27. The inner side of the sliding block 32 is provided with an internal thread that matches the transmission screw 31, and the outer side is slidably connected to the slide rail on the inner wall of the positioning housing 30. The slide rail adopts a linear guide structure to ensure that the sliding block 32 moves smoothly in a straight line under the drive of the transmission screw 31. The drive device 33 installed at one end of the transmission screw 31 is a small servo motor or stepper motor. The motor output shaft is connected to the transmission screw 31 through a coupling. The rotation speed and direction can be adjusted by the control system to realize the precise start, stop and reciprocating motion of the sliding block 32. The bottom surface of the cleaning scraper 34 is completely in contact with the bottom surface of the ink guiding channel 27. The contact force is adjusted by the length of the connecting rod 35 and the installation angle, which can effectively scrape off the waste ink residue attached to the bottom of the ink guiding channel 27 without scratching the inner wall of the channel. The top surface of the cleaning scraper 34 is designed to be arc-shaped, which can reduce the resistance when waste ink flows and prevent residue from accumulating on the top of the scraper.

[0050] When waste ink accumulates in the ink guiding channel 27 and affects the flow, the drive device 33 drives the transmission screw 31 to rotate, the sliding block 32 moves along the slide rail, and drives the cleaning scraper 34 to slide back and forth at the bottom of the ink guiding channel 27 through the connecting rod 35, pushing the residue to the waste discharge port 29 for discharge, realizing automatic cleaning of the channel, reducing the frequency of manual cleaning, and ensuring the smooth transport of waste ink.
