Description

Technical Field

[0001] This invention relates to the field of laser holographic image manufacturing equipment technology, and in particular to a cross-linked film 3D nano-image laser holographic image device. Background Technology

[0002] Laser holographic images and 3D nanostructure images are widely used in packaging, decoration, and anti-counterfeiting labels due to their unique visual effects and anti-counterfeiting properties. In the field of 3D nanographic embossing, especially in the fine pattern transfer process of flexible materials such as cross-linked films, flexographic embossing technology is commonly used. This combines flexographic printing and UV embossing, applying UV adhesive to the pattern on a nickel plate, precisely embossing and curing it onto a thin film substrate, thus forming a 3D nanographic pattern with a three-dimensional effect. However, in the production process, especially when multi-layer overprinting or precise positioning is required, the following technical challenges exist: Current 3D nano-graphic printing and high-precision overprinting technologies are often carried out in steps, from coating, alignment, imprinting to curing. Each process is often carried out independently, and material transfer between processes is prone to errors, resulting in low production efficiency and the inability to achieve real-time alignment and continuous production of multi-layer micro-nano structures. Second, traditional computer overprinting systems can adjust the printing plate by changing the cursor position. However, when printing transparent binders and transparent UV imaging materials on cross-linked films, the computer overprinting system cannot recognize them, resulting in signal acquisition failure or extreme instability, which leads to inaccurate overprinting. Third, due to the high viscosity of UV adhesive, it is difficult to control the amount of adhesive applied using conventional gravure printing. This results in uneven adhesive thickness transferred to the flexographic roller and inaccurate control of the amount of adhesive applied, affecting the resolution and consistency of the final printed pattern.

[0003] Therefore, there is an urgent need for an automated device that can integrate high-precision alignment, controllable coating, precision imprinting and rapid curing to achieve continuous, stable and high-quality production of 3D nano-image laser holographic images on cross-linked films.

Beneficial effects

[0017] 1. This application integrates cursor printing, cursor detection, printing roller phase detection, and closed-loop alignment compensation into a single production line, using an integrated frame connection. This eliminates the cumulative errors caused by traditional multi-process transfers, achieving a deep integration of high-precision registration and continuous production. By setting up dedicated first and second photoelectric eyes to detect the colored registration cursor and printing roller phase mark respectively, the problem of signal acquisition failure in traditional computer color matching systems on transparent materials is effectively solved, achieving stable and high-precision registration on cross-linked films.

[0018] 2.

Combined with a glue tank height adjustment device for immersion depth, this four-level collaborative control mechanism enables extremely precise control over the UV adhesive layer transferred onto the flexographic roller from macroscopic pressure, microscopic gap, doctor blade posture, and adhesive supply source. This ensures highly uniform adhesive layer thickness and precise quantitative control. By constructing a multi-dimensional, high-precision adhesive amount collaborative control system, a crucial foundation is laid for replicating high-resolution, high-fidelity 3D nanostructures.

[0019] 3. Cooling channels are installed inside the printing roller and the printing plate roller, through which a constant-temperature cooling medium is introduced. This effectively counteracts the frictional heat and curing heat generated during the printing process, keeping the roller surface temperature stable. This prevents graphic distortion or misregistration caused by thermal expansion, and also avoids the UV adhesive from pre-curing on the roller surface, ensuring the consistency of the printed graphic and the sharpness of the edges.

The first scraper position adjustment device integrates coarse height adjustment, fine angle adjustment, and front and rear locking functions; the floating roller height adjustment device enables rapid adjustment of the film path to compensate for a large range of alignment deviations, allowing the equipment to flexibly adapt to different process parameters and film characteristics. The adjustment process is intuitive and reliable, reducing reliance on operator experience. Attached Figure Description

Detailed Implementation

[0023] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0024] Example 1

[0025] A cross-linked membrane 3D nano-image laser holographic imaging device, such as Figures 1-17 As shown, it includes the following components arranged sequentially along the transport direction of the cross-linked membrane: Unwinding assembly 1 is used for unwinding film material; Printing component 2 is used to print alignment marks on the film material; The overprinting alignment component 3 is used to achieve closed-loop overprinting alignment based on cursor recognition and printing plate roller phase detection. The overprinting alignment component 3 includes a first photoelectric eye 31 and a second photoelectric eye 32, which are used to identify and detect the position of the alignment cursor and detect the phase signal of the printing plate roller, respectively. The control system receives the position signal and the phase signal, compares and calculates their deviation, and then drives the actuator of the overprinting alignment component 3 to perform real-time alignment compensation. The flexographic printing assembly 4 is used to coat a curable resin onto a film and perform nanostructure imprinting. The flexographic printing assembly 4 includes an adhesive application control device 20 for providing a UV adhesive layer. Winding assembly 5 is used to wind up the film material.

[0026] This equipment adopts an integrated, serial layout. The film material is released by the unwinding assembly 1, and sequentially passes through the printing and registration unit. The printing assembly 2 first prints the markings, then the registration assembly 3 checks the alignment, and the flexographic printing assembly 4 applies adhesive, prints, and cures the film material. Finally, it is wound up by the rewinding assembly 5. All components are connected by a rigid crossbeam, ensuring the overall stability of the equipment and the alignment reference between each station. The guide rollers on the crossbeam ensure smooth film material transport and precise path accuracy.

[0027] like Figures 1-5 The printing assembly 2 and the registration assembly 3 are both mounted on the first stand 6, and each includes a first squeegee position adjustment device 7, a film tensioning device 8, a first motor 9, a drive device 10, a printing plate shaft 11, and a scale 12. The film tensioning device 8 and the first squeegee position adjustment device 7 are both located between the two first stands 6. The first squeegee position adjustment device 7 is used to scrape off excess glue from the film surface. The first motor 9 is located on one side of the first stand 6, and the drive device 10 is located on the other side of the first stand 6. The printing plate shaft 11 is located on the output ends of the first motor 9 and the drive device 10, respectively. The scale 12 is located on the printing plate shaft 11 near the first motor 9. The first photoelectric eye 31 is connected between the two first stands 6, and the second photoelectric eye 32 is located above the first motor 9.

[0028] It should be noted that in this embodiment, the printing component 2 and the registration component 3 share the same mechanical actuator, and the two are physically integrated. To describe their functions in different processes, the following text refers to the mechanism as the printing component 2 and the registration component 3 in the printing cursor stage and the registration detection stage, respectively. The mechanical actuator is mounted on the first stand 6, which serves as the support structure for the printing component 2 and the registration component 3, providing a mounting base for other components. The film tensioning device 8 is used to maintain the tension stability of the crosslinked film during the transmission process, ensuring the flatness of the crosslinked film and avoiding wrinkles or loosening that could affect the printing effect. The position and movement of the first doctor blade position adjustment device 7 are controlled to achieve coating or doctoring operations during the printing process.

[0029] In detail, the drive device 10 includes a servo motor, a synchronous belt and a ball screw. The servo motor is mounted on a stand on the side away from the first motor 9. The ball screw is connected to the printing shaft 11. The synchronous belt is located between the output end of the servo motor and the ball screw.

[0030] The printing plate shaft 11 is connected to the first motor 9 via a coupling. Specifically, the printing plate is connected between the printing plate shafts 11 on both sides (not shown in the printing plate diagram). The rotation of the first motor 9 drives the printing plate shaft 11 on it to rotate, thereby driving the printing plate to rotate. At the same time, the rotation of the servo motor transmits power to the ball screw through the synchronous belt, thereby driving the ball screw to rotate and realizing the left and right movement of the printing plate shaft 11 on it, thus adjusting the position of the printing plate.

[0031] When the cross-linked film passes through the printing component 2, the printing component 2 prints a specific shape and color cursor, such as a letter or triangle, at a specific position on the cross-linked film. This cursor serves as the reference for subsequent overprinting. The cross-linked film carrying the cursor enters the overprinting alignment component 3, which has an identical structure. After the cross-linked film passes through the printing plate of the overprinting alignment component 3, the first photoelectric eye 31 on the overprinting alignment component 3 identifies and detects the alignment cursor printed by the printing component 2 on the cross-linked film, generating a new waveform curve one. At the same time, the second photoelectric eye 32 detects the scale 12 of its own plate axis 11, generating its own plate axis signal and generating wave curve two. The operator aligns and locks the peaks of the cursor waveform and the plate axis waveform detected by the overprinting alignment component 3 on the screen. The system calculates and remembers the positional relationship between the two at this time, and this relationship is set as the "correct" standard. After manual plate alignment is completed, the positions of the two peaks of curve one and curve two are locked in a certain area on the color matching screen, and the deviation value is calculated by the PLC as a reference. During the production process, if the peak deviation value changes, the PLC detects and calculates the change and controls the first motor 9 to make fine adjustments to ensure accurate overprinting.

[0032] like Figures 6-8The first scraper position adjustment device 7 includes a first support frame 71, a second rotating shaft 72, a connecting rod 73, a first housing 74, a first turntable 75, a rack 76, a worm gear assembly 77, an angle adjustment device 78, a front-to-back adjustment device 79, a clamping device 710, a mounting plate 711, and a first scraper 712. The first support frame 71 is respectively mounted on two first uprights 6. The second rotating shaft 72 is rotatably mounted between the first support frames 71. The connecting rod 73 is mounted between the first support frames 71 and located below the second rotating shaft 72. A housing 74 passes through a second rotating shaft 72 and a connecting rod 73. A first turntable 75 is rotatably mounted on the first housing 74. A rack 76 is slidably mounted on the top of the first housing 74. A worm gear assembly 77 is mounted between the rack 76 and the first turntable 75. An angle adjustment device 78 is mounted on the top of the rack 76. A front-to-back adjustment device 79 is mounted on the angle adjustment device 78. A mounting plate 711 is mounted on the front-to-back adjustment device 79. A first scraper 712 is slidably mounted on the mounting plate 711. A clamping device 710 is mounted on the mounting plate 711. The angle adjustment device 78 includes a second housing 781, a second support frame 782, a third rotating shaft 783, and a second turntable 784. The second housing 781 and the second support frame 782 are respectively disposed on the top of the racks 76 on both sides. The third rotating shaft 783 is rotatably disposed between the second housing 781 and the second support frame 782. The second turntable 784 is rotatably disposed on the second housing 781. A worm gear assembly 77 is also disposed between the second turntable 784 and the third rotating shaft 783. The front and rear adjustment device 79 includes a clamping seat 791 and a threaded rod 792. The clamping seat 791 is disposed on both sides of the second rotating shaft 72. The threaded rod 792 passes through the clamping seat 791 and the mounting plate 711 and is connected to the first scraper 712.

[0033] When the first turntable 75 is rotated, the rack 76 is driven to slide up and down on the top of the first housing 74 via the worm gear assembly 77. An angle adjustment device 78 is located on the top of the rack 76 and moves up and down as the rack 76 slides. The mounting plate 711 and the first scraper 712 are both mounted on the angle adjustment device 78. The up and down movement of the angle adjustment device 78 causes the first scraper 712 to move up and down. In this way, rotating the first turntable 75 allows for the initial adjustment of the angle position of the first scraper 712.

[0034] Rotating the second turntable 784 drives the third rotating shaft 783 to rotate via the worm gear assembly 77. The rotation of the third rotating shaft 783 drives the mounting plate 711 and the first scraper 712 to rotate as a whole, thereby achieving further fine adjustment of the angle of the first scraper 712 to meet the precise requirements of different embossing processes for the angle of the first scraper 712.

[0035] In detail, the clamping device 710 includes a clamp and a locking handle. The clamp is mounted on the mounting plate 711, and the locking handle is mounted on the clamp. The bottom of the locking handle contacts and engages with the first scraper 712.

[0036] When the threaded rod 792 is rotated, the mounting plate 711 provides axial restraint to the threaded rod 792. The rotation of the threaded rod 792 pushes the first scraper 712 to slide back and forth on the mounting plate 711, thus adjusting the position of the first scraper 712. After the first scraper 712 is adjusted to the appropriate position, tighten the locking handle to firmly press its bottom against the first scraper 712, fixing the first scraper 712 in its current position and preventing it from moving during the imprinting process, ensuring the stability of the imprinting process.

[0037] like Figure 9 The membrane tensioning device 8 includes a first rotating shaft 81, an L-shaped component 82, a tensioning roller 83, and a rubber roller 84. The first rotating shaft 81 is rotatably mounted on the lower side of the two first uprights 6. The L-shaped component 82 is mounted on the first rotating shaft 81. The tensioning roller 83 and the rubber roller 84 are respectively mounted on the two ends of the L-shaped component 82.

[0038] When the rubber roller 84 comes into contact with the crosslinked film transmitted by the tension roller 83, it will be lifted. When lifted, the L-shaped part 82 will move through the first rotating shaft 81. The L-shaped part 82 will drive the tension roller 83 to tighten the crosslinked film, so that the crosslinked film can be transferred from the printing component 2 to the registration assembly 3 through the guide roller.

[0039] like Figures 10-11 The flexographic printing assembly 4 also includes a second support frame 13, a second squeegee position adjustment device 14, a floating roller height adjustment device 15, a glue tank height adjustment device 16, an impression roller 17, an impression plate roller 18, and an LED light 19. The glue application control device 20 is located between the lower sides of the second support frame 13, the second squeegee position adjustment device 14 is located on the glue application control device 20, the floating roller height adjustment device 15 is located between the lower sides of the second support frame 13 and on the glue application control device 20, the impression roller 17 and the impression plate roller 18 are located between the upper sides of the second support frame 13 on both sides, and both the impression roller 17 and the impression plate roller 18 are provided with cooling channels inside. The cooling channels are used to introduce cooling medium so that the surface of the impression roller 17 and the impression plate roller 18 maintains the set operating temperature. The LED light 19 is located on the upper side of the second support frame 13 and is located directly above the impression plate roller 18. The LED light 19 is used to irradiate the UV glue to cure it.

[0040] The amount of adhesive applied to the film is precisely adjusted by the cooperation of the second scraper position adjustment device 14, the adhesive tank height adjustment device 16, and the adhesive application control device 20. The prepared nickel plate is attached to the printing plate roller 18, and the film and UV adhesive are pressed onto the printing plate roller by the printing adhesive roller 17. At this time, the LED light 19 shines on the film, and the UV adhesive is instantly cured, replicating the three-dimensional pattern on the nickel plate onto the UV adhesive, so that the UV adhesive on the film presents a 3D three-dimensional effect.

[0041] like Figures 12-13 The gluing control device 20 includes a displacement device 201, a transfer roller 202, an anilox roller 203, and a flexographic roller 204. The displacement device 201 is located on the lower side between the second uprights 13. The transfer roller 202 and the anilox roller 203 are both mounted on the displacement device 201 and are adjacent to each other. The flexographic roller 204 is located between the second uprights 13 and is adjacent to the transfer roller 202. The second doctor blade position adjustment device 14 is mounted on the displacement device 201. Anilox roller 203 applies adhesive to glue tank 162. Second doctor blade position adjustment device 14 scrapes off excess adhesive from anilox roller 203, ensuring accurate adhesive application. Transfer roller 202 and anilox roller 203 rotate synchronously in contact, transferring adhesive to transfer roller 202. Transfer roller 202 then rotates synchronously in contact with flexographic roller 204, transferring adhesive to flexographic roller 204. Flexographic roller 204 rotates synchronously in contact with film, transferring adhesive onto film.

[0042] like Figures 13-14 The displacement device 201 includes a base plate 2011, a first slide rail 2012, a movable seat 2013, a support frame 2014, a first cylinder 2015, and a lifting device 2016. The base plate 2011 is disposed between the second uprights 13 on both sides. The first slide rails 2012 are symmetrically disposed on the base plate 2011. The movable seat 2013 is slidably disposed between the first slide rails 2012. The support frames 2014 are respectively disposed on the side walls of the second uprights 13 on both sides. The first cylinders 2015 are all disposed on the support frames 2014. The output end of the first cylinder 2015 is connected to the movable seat 2013. The first cylinder 2015 drives the movable seat 2013 to move along the first slide rail 2012. The second scraper position adjustment device 14 is set on the movable seat 2013. The anilox roller 203 is set on the upper side of the movable seat 2013. The lifting device 2016 is set on both sides of the top of the movable seat 2013. The lifting device 2016 is used to adjust the height of the transfer roller 202. The transfer roller 202 is set between the lifting devices 2016.

[0043] When the first cylinder 2015 operates, its output end extends and retracts, driving the movable seat 2013 to move along the first slide rail 2012, thereby adjusting the horizontal position of the transfer roller 202 and thus changing the relative position between the transfer roller 202 and the flexographic roller 204 to meet the requirements of different processes for glue transfer position. The anilox roller 203 is located on the upper side of the movable seat 2013 and moves with the movable seat 2013 to ensure a stable relative position with the transfer roller 202, facilitating glue transfer. The lifting device 2016 is used to adjust the height of the transfer roller 202. By adjusting the height of the transfer roller 202, the contact pressure between the transfer roller 202 and the anilox roller 203 and the flexographic roller 204 can be controlled, thereby affecting the amount and quality of glue transfer.

[0044] like Figure 17 The lifting device 2016 includes a second slide rail 21, a first slider 22 and a first lead screw 23. The second slide rail 21 is respectively arranged on both sides of the top of the movable seat 2013. The first sliders 22 are all slidably arranged on the second slide rail 21. The first lead screw 23 is arranged on the second slide rail 21 and passes through the second slide rail 21. The transfer roller 202 is connected between the two first sliders 22.

[0045] By controlling the rotation of the first lead screw 23, under the limiting action of the second slide rail 21, the rotation of the first lead screw 23 will drive the first slider 22 to move along the second slide rail 21, thereby driving the transfer roller 202 to move up and down. By adjusting the height of the transfer roller 202, the contact pressure between the transfer roller 202 and the anilox roller 203 and the flexographic roller 204 can be controlled, thereby affecting the amount and quality of glue transfer.

[0046] like Figure 15 The second scraper position adjustment device 14 includes a rotating rod 141, a connecting block 142, a second cylinder 143, a third slide rail 144, a second slider 145, a second lead screw 146, a second scraper 147, and an angle adjustment device 148. The rotating rod 141 is rotatably mounted on the movable seat 2013. The connecting block 142 is mounted on both sides of the rotating rod 141. The second cylinder 143 is mounted on the connecting block 142. The third slide rail 144 is mounted on the output end of the second cylinder 143. The second slider 145 is slidably mounted on the third slide rail 144. The second lead screw 146 is rotatably mounted on the third slide rail 144 and passes through the second slider 145. The second scraper 147 is connected between the second slider 145. The angle adjustment device 148 is connected between the side wall of the movable seat 2013 and the rotating rod 141.

[0047] The rotating rod 141 can rotate around its own axis. The rotation angle of the rotating rod 141 can be adjusted by the angle adjustment component, thereby changing the angle of the second scraper 147 to adapt to the scraping requirements of different anilox rollers 203 and glue application amounts. When the second cylinder 143 is working, its output end extends and retracts, driving the third slide rail 144 to move in the vertical direction, thereby adjusting the vertical distance between the second scraper 147 and the anilox roller 203 and controlling the scraping pressure of the second scraper 147 on the anilox roller 203. By rotating the second lead screw 146, the second slider 145 is driven to move horizontally on the third slide rail 144 using the thread transmission principle between the lead screw and the slider. The second scraper 147 is connected between the second slider 145 and its horizontal position is adjusted as the second slider 145 moves. This allows the position of the second scraper 147 to be adjusted in three dimensions, thereby precisely controlling the scraping of glue at different positions on the anilox roller 203 by the second scraper 147 and ensuring the uniformity of the glue application. In detail, the angle adjustment device 148 is existing technology and will not be described in detail here.

[0048] like Figure 16 The floating roller height adjustment device 15 includes a second motor 151, a fourth rotating shaft 152, a bevel gear set 153, a third lead screw 154, a fourth slide rail 155, a third slider 156, and a floating roller 157. The second motor 151 is mounted on a second support 13 on one side. The fourth rotating shaft 152 is mounted between the two second supports 13 and is connected to the output end of the second motor 151. The fourth slide rail 155 is mounted on the inner side of the second supports 13 on both sides. The third sliders 156 are slidably mounted on the fourth slide rail 155. The third lead screw 154 rotates through the third sliders 156 mounted on the fourth slide rail 155. The bevel gear set 153 is mounted between the third lead screw 154 and the fourth rotating shaft 152. The floating roller 157 is mounted between the two third sliders 156.

[0049] When the motor is working, it drives the rotating shaft to rotate, providing power to the entire floating roller height adjustment device 15. The rotation of the rotating shaft is transmitted to the third lead screw 154 through the bevel gear set 153, causing the third lead screw 154 to rotate. When the third lead screw 154 rotates, it drives the third slider 156 to move up and down on the fourth slide rail 155 using the threaded transmission principle between the lead screw and the slider. The height is adjusted as the third slider 156 moves. When the glue application position of the flexographic roller 204 deviates significantly from that of the printing plate roller 18, the film transmission path can be changed by adjusting the up and down position of the floating roller 157, thus achieving plate alignment and ensuring the accuracy of the printed pattern.

[0050] like Figure 14 The glue tank height adjustment device 16 includes a third cylinder 161 and a glue tank 162. The third cylinder 161 is mounted on the movable seat 2013, and the glue tank 162 is mounted on the output end of the third cylinder 161.

[0051] When the third cylinder 161 operates, its output end extends and retracts, causing the glue tank 162 to move up and down, thereby adjusting the height of the glue tank 162. The glue tank 162 is located directly below the anilox roller 203, facilitating the immersion of the anilox roller 203 in the glue tank 162 to obtain glue. By adjusting the height of the glue tank 162 through the glue tank height adjustment device 16, the contact depth between the anilox roller 203 and the glue in the glue tank 162 can be controlled, thereby controlling the amount of glue applied to the anilox roller 203 and ensuring the uniformity and stability of the glue application.

[0052] The unwinding assembly 1, printing assembly 2, registration assembly 3, flexographic printing assembly 4, and rewinding assembly 5 are all connected by a crossbeam to form an integrated structure, and the crossbeam is equipped with several guide rollers.

[0053] Specific workflow and working principle: (a) Unloading stage The unwinding assembly 1 begins operation, releasing the cross-linked film material. Guided by the guide rollers, the film material is smoothly transferred to subsequent assemblies, providing the base film material for subsequent printing, registration, and embossing processes.

[0054] (II) Printing Stage Printing preparation: The film tensioning device 8 maintains stable tension of the cross-linked film during transport through the coordinated action of the first rotating shaft 81, L-shaped component 82, tensioning roller 83, and rubber roller 84. When the rubber roller 84 contacts the cross-linked film transmitted by the tensioning roller 83, it lifts up, and the first rotating shaft 81 drives the L-shaped component 82 to move, thereby driving the tensioning roller 83 to tighten the cross-linked film, ensuring the film is flat and avoiding wrinkles or looseness that would affect the subsequent printing effect.

[0055] Printing process: The first motor 9 is connected to the printing plate shaft 11 via a coupling, and the printing plate is connected between the printing plate shafts 11 on both sides. The rotation of the first motor 9 drives the printing plate shaft 11 to rotate, thereby causing the printing plate to rotate. At the same time, the servo motor in the drive device 10 rotates, transmitting power to the ball screw via a synchronous belt, causing the ball screw to rotate, realizing the left and right movement of the printing plate shaft 11, and adjusting the position of the printing plate. During the cross-linking film transfer process, the printing plate prints specific colored and shaped cursors, such as "—" or "triangle," at specific positions on the cross-linking film. These cursors serve as the reference for subsequent overprinting.

[0056] (III) Overprinting and Alignment Stage Alignment preparation: The structure of the registration assembly 3 is basically the same as that of the printing assembly 2, and it is also installed on the first stand 6. The cross-linked film carrying the printed cursor enters the registration assembly 3. After passing through its printing plate, the registration assembly 3 begins to work.

[0057] Signal detection: The first photoelectric eye 31 is connected between the two first supports 6 to identify and detect the alignment mark printed by the printing component 2 on the cross-linked film and generate waveform curve one; the second photoelectric eye 32 is located above the first motor 9 and detects the scale 12 of its own plate axis 11 to generate the plate axis signal, i.e., wave curve two.

[0058] Manual alignment: The operator aligns and locks the peaks of the detected cursor waveform and the printing axis waveform on the screen. The system calculates and remembers the positional relationship between the two at this time and sets it as the "correct" standard. After manual alignment is completed, the positions of the two peaks of curve one and curve two are locked in a certain area on the color matching screen, and the deviation value is calculated by the PLC as a reference.

[0059] Automatic alignment compensation: During the production process, if the peak deviation value changes, the PLC detects and calculates the change and controls the first motor 9 to make a fine adjustment, which drives the plate shaft 11 and the printing plate to move, ensuring the accuracy of the registration and realizing closed-loop registration alignment.

[0060] (iv) Flexographic printing stage Preparation for gluing: Control the first cylinder 2015 to work. The output end of the first cylinder 2015 is connected to the moving base 2013, which can drive the moving base 2013 to move along the first slide rail 2012 and adjust the horizontal position of the transfer glue roller 202.

[0061] Glue Transfer: The anilox roller 203 applies glue in the glue tank 162. The second squeegee position adjustment device 14 scrapes off excess glue from the anilox roller 203, ensuring accurate glue application. The transfer roller 202 and the anilox roller 203 rotate synchronously in contact, transferring the glue to the transfer roller 202. The transfer roller 202 then rotates synchronously in contact with the flexographic roller 204, transferring the glue to the flexographic roller 204. The flexographic roller 204 rotates synchronously in contact with the film, transferring the glue onto the film. The second squeegee position adjustment device 14 can precisely adjust the position of the second squeegee 147 in three dimensions to control the removal of glue from the anilox roller 203, ensuring uniform glue application.

[0062] Height Adjustment: Lifting devices 2016 are located on both sides of the top of the movable base 2013. By controlling the rotation of the first lead screw 23, the first slider 22 moves along the second slide rail 21, which in turn moves the transfer roller 202 up and down, adjusting the contact pressure between the transfer roller 202 and the anilox roller 203 and flexographic roller 204, thus affecting the amount and quality of glue transfer. The third cylinder 161 of the glue tank height adjustment device 16 operates, moving the glue tank 162 up and down, controlling the contact depth between the anilox roller 203 and the glue in the glue tank 162, ensuring uniform and stable glue application.

[0063] Imprinting and curing Imprinting preparation: The second motor 151 of the floating roller height adjustment device 15 operates, driving the fourth rotating shaft 152 to rotate. Power is transmitted to the third lead screw 154 via the bevel gear set 153, causing the third lead screw 154 to rotate. The third slider 156 moves up and down on the fourth slide rail 155, driving the floating roller 157 to achieve height adjustment. When the adhesive application position of the flexographic roller 204 deviates significantly from that of the printing plate roller 18, the vertical position of the floating roller 157 is adjusted to change the film transport path, achieving plate alignment and ensuring the accuracy of the imprinted pattern.

[0064] Imprinting process: The prepared nickel plate is attached to the imprinting roller 18. The imprinting adhesive roller 17 and the imprinting roller 18 are positioned between the upper sides of the second uprights 13 on both sides. Both rollers have cooling channels inside, through which cooling medium can be introduced to maintain the set operating temperature on the surface. The film and the film with adhesive are pressed onto the imprinting roller 18 by the imprinting adhesive roller 17.

[0065] Curing and molding: LED light 19 is positioned directly above the printing roller 18 to irradiate the UV adhesive and cure it instantly, thus replicating the three-dimensional pattern on the nickel plate onto the UV adhesive, giving the UV adhesive on the film a 3D effect.

[0066] (v) Collection Stage The winding assembly 5 winds up the cross-linked membrane material after the above-mentioned process, thus completing the entire process of creating the cross-linked membrane 3D nano-image laser holographic image.

[0067] Through the coordinated operation of the above components, this equipment can accurately create 3D nano-image laser holographic effects on cross-linked films, meeting the requirements for high-quality image production.
