Detailed Implementation

[0031] The present invention will be further described in detail below with reference to specific embodiments.

[0032] Example 1

[0033] like Figure 1-2 As shown, this embodiment provides a dual-blade slurry coating structure based on photocuring, comprising:

[0034] Support frame 41 is used to connect with the frame 1 of the photocurable molding equipment; specifically, support frame 41 is fixed on the working platform of frame 1, and support frame 41 can be prepared by profile processing.

[0035] The drive motor 42 is mounted on the support frame 41; the drive motor 42 is an existing rotary motor, which will not be described in detail here.

[0036] The transmission component is connected to the output shaft of the drive motor 42. The transmission component can be a belt drive structure, a gear drive structure, etc., as long as it can transmit the power of the drive motor 42 to make the scraper shaft 46 rotate relative to the support frame 41.

[0037] The scraper shaft 46 is connected to the transmission assembly and rotatably connected to the support frame 41. The scraper shaft 46 is rotatably connected to the support frame 41 via bearings (i.e., the scraper shaft 46 is rotatably connected to the motor adapter plate 43 via bearings, allowing it to rotate relative to the support frame 41). The motor adapter plate 43 is fixed on the support frame. The drive motor is fixedly connected to the motor adapter plate 43 via screws. The output shaft of the drive motor passes through the motor adapter plate 43 and is fixedly connected to the synchronous pulley 44. The scraper shaft 46 passes through the motor adapter plate 43 and is connected to the synchronous pulley 44.

[0038] There are two sets of scraper assemblies 47. Both sets of scraper assemblies 47 are connected to the scraper shaft 46. The two sets of scraper assemblies 47 are symmetrically distributed along the center of the scraper shaft 46. Both sets of scraper assemblies 47 are used to spread the slurry on the printing platform 21 of the photocuring molding equipment.

[0039] The transmission assembly in this embodiment includes a synchronous belt 45 and synchronous pulleys 44. There are two synchronous pulleys 44. The two synchronous pulleys 44 are fixedly connected to the scraper shaft 46 and the output shaft of the drive motor 42, respectively. The synchronous belt 45 is connected to the two synchronous pulleys 44.

[0040] Each scraper assembly 47 includes a hand-tightening nut 471, a scraper holder 472, an upper scraper holder 473, a spring 474, a middle scraper holder 475, a lower scraper holder 476, a scraper clamping plate 477, and a blade 478. The scraper holder 472 is fixedly connected to the scraper shaft 46, and the upper scraper holder 473 is fixedly connected to the scraper holder 472. The upper scraper holder 473 and the middle scraper holder 475 are connected by the hand-tightening nut 471 and a connecting bolt. The spring 474 is sleeved on the outside of the connecting bolt and is located between the upper scraper holder 473 and the middle scraper holder 475. The connecting bolt can slide relative to the upper scraper holder 473. The middle scraper holder 475 and the lower scraper holder 476 are adjustablely connected, and the blade 478 is clamped and fixed to the lower scraper holder 476 by the scraper clamping plate 477. Specifically, the scraper clamp 477 is fixedly connected to the lower scraper holder 476 by bolts. The scraper shaft 46 has threaded holes in its axial direction. The scraper holder 472 is fixed to the scraper shaft 46 by bolts fitting into the threaded holes. The scraper holder 472 has four through holes, and two bolts pass through two of these through holes to fix it to the upper scraper holder 473. The upper scraper holder 473 has two through holes, and a hand-tightened nut 471 passes through the other two through holes of the scraper holder 472 and the two through holes of the upper scraper holder 473. The through hole is connected to the middle blade holder 475 of the scraper. The middle blade holder 475 can slide within the upper blade holder 473 of the scraper. The spring 474 can reset the middle blade holder 475 when it slides into the upper blade holder 473 of the scraper. The principle is that the hand-tightening nut 471 can slide through the through hole of the scraper holder 472 and the upper blade holder 473 of the scraper. The outer diameter of the end of the hand-tightening nut 471 is larger than the inner diameter of the through hole, so that the hand-tightening nut 471 cannot pass through the through hole of the scraper holder 472, thus restricting the hand-tightening nut 471 from falling off.

[0041] Both the middle blade holder 475 and the lower blade holder 476 of the scraper are equipped with lugs, each with a connecting hole. Two lugs are connected to a nut via bolts passing through the two connecting holes. Specifically, the lower blade holder 476 and the middle blade holder 475 form an angle. This is achieved by loosening the nut, allowing the middle blade holder 475 and the lower blade holder 476 to rotate relative to each other via the lugs. After adjusting the relative angle, tightening the nut completes the adjustment. This design ensures that the thickness of the slurry is uniform and accurate each time it is applied, thus achieving efficient and uniform application of each layer of slurry and ensuring the quality and precision of the printed parts.

[0042] The innovative dual-scraper slurry spreading structure 4 in the above embodiments uses a dual-scraper assembly 47, which only needs to be used with dual forming cylinders to efficiently spread slurry on the printing platform 21. At the same time, excess slurry can be recycled during the spreading process.

[0043] This technology solves the problems of slurry waste, low spreading efficiency, and poor uniformity in existing technologies. Furthermore, by improving slurry utilization and equipment efficiency, it significantly reduces production costs. This enables it to meet the requirements of higher production efficiency and plays a crucial role in high-precision, high-quality printing processes.

[0044] Therefore, the dual-scraper slurry coating structure 4 is not only of great significance in improving the efficiency and economy of photopolymer additive manufacturing technology, but also provides beneficial technical support and innovative direction for the further development of additive manufacturing equipment in the future.

[0045] Example 2

[0046] like Figure 1-5 As shown, this embodiment provides a photopolymerization molding device, including a frame 1, a molding feeding module 2, a photopolymerization module 3, and a dual-scraper slurry spreading structure 4. The frame 1 has a working platform, the photopolymerization module 3 is positioned above the working platform, and the dual-scraper slurry spreading structure 4 is positioned on the working platform. The molding feeding module 2 includes a first molding cylinder, a second molding cylinder, and a feeding module. The working platform has a first station, a second station, a third station, and a fourth station. The scraper of the dual-scraper slurry spreading structure 4 can rotate sequentially through the first station, the second station, the third station, and the fourth station. The first molding cylinder and the second molding cylinder are connected to the second station and the fourth station, respectively, and the feeding module is connected to the first station. Specifically, the frame 1 supports other structures and provides a stable working platform. The molding feeding module 2 delivers a quantitative amount of slurry to the printing platform 21, laying the foundation for uniform slurry spreading. The photopolymerization module 3 provides energy through a photomechanical unit 31 to perform layer-by-layer curing, ensuring precise curing of the slurry during the printing process. The dual-scraper slurry spreading structure 4 achieves high-speed slurry spreading and material recycling on the printing platform 21 through two sets of scraper assemblies 47.

[0047] The first station has a first through hole, through which the feeding module communicates. The feeding module includes a feeding interface, a peristaltic pump 24, and a feeding container. The peristaltic pump 24 and the feeding container are connected via a feeding pipe, and the peristaltic pump 24 and the feeding interface are connected via a connecting hose. The feeding interface communicates with the first through hole. The peristaltic pump 24 ensures a stable and precise supply and control of the slurry, avoiding waste or insufficient supply, and preventing the problems of slurry waste and uneven feeding found in traditional equipment.

[0048] The first and second forming cylinders have the same structure. Both include a printing platform 21, a forming cylinder body, a piston 25, an electric push rod 26, and an electric push rod adapter plate 27. The electric push rod adapter plate 27 is fixedly connected to the bottom of the forming cylinder. The movable end of the electric push rod 26 passes through the electric push rod adapter plate 27 and is fixedly connected to the piston 25. The piston 25 is slidably connected to the forming cylinder. The printing platform 21 is connected to the top surface of the piston 25. The second and fourth workstations are respectively provided with a second through hole and a fourth through hole. The printing platform 21 of the first and second forming cylinder structures is embedded in the second through hole and the fourth through hole, respectively, and the printing platform 21 of the first and second forming cylinder structures can slide relative to the second through hole and the fourth through hole, respectively. Specifically, the movable end of the electric push rod 26 can slide relative to the electric push rod adapter plate 27. The printing platform 21 is used to support the parts printed during the forming process. The two forming cylinders are located below the platform of the frame 1. After the electric push rod 26 under the forming cylinder moves the printing platform 21 to the printing plane via the piston 25, the two sets of scraper assemblies 47 are divided into a first scraper assembly 47 and a second scraper assembly 47. The drive motor 42 drives the first scraper assembly 47 to reset to the first station. The peristaltic pump 24 supplies the slurry to the feed port 23 through the pipeline. The drive motor 42 drives the first scraper assembly 47 mounted on the scraper shaft 46 to rotate 180° via the synchronous belt 45. During this process, the first scraper assembly 47 moves the printing platform 21... The slurry is scraped onto the printing platform 21 (second station) of the first forming cylinder 22 for photocuring. The peristaltic pump 24 then supplies the slurry to the feed port 23 through pipelines. The first scraper assembly 47 then rotates 180°, at which point it spreads the slurry onto the printing platform 21 (fourth station) of the second forming cylinder for photocuring. Excess slurry is then scraped back to the feed port 23, and the second scraper assembly 47 scrapes the slurry at the feed port 23 onto the printing platform 21 of the first forming cylinder 22 for photocuring. After entering the cycle, during one rotation of the scraper shaft 46, the two layers of slurry in the two forming cylinders are photocured, and the excess slurry is recycled, achieving high-speed slurry spreading and recycling.

[0049] The work platform is provided with a circular groove, which is divided into four equal parts: the first station, the second station, the third station, and the fourth station. The scrapers of the first scraper assembly 47 and the second scraper assembly 47 rotate in the circular groove. The printing plane is the bottom plane of the circular groove, which is the surface in contact with the blade.

[0050] The photopolymerization module 3 includes two photomechanical units 31, which correspond to the second station and the fourth station, respectively.

[0051] The photomechanical mounting plate 33 is fixedly connected to the frame 1. Each photomechanical unit 31 has a protective shell 32 on its circumferential surface, which is mounted on the photomechanical mounting plate 33. The photomechanical mounting plate 33 is fixed to the frame 1 by bolts. The photomechanical unit 31 provides an energy source to cure the ink layer by layer during the printing process. The protective shell 32 protects the photomechanical unit 31 from external environmental factors, thereby extending its service life. The photomechanical mounting plate 33 securely mounts the photomechanical unit 31 to the frame 1, ensuring that the photomechanical unit 31 maintains precise positioning during the curing process to guarantee uniform curing of each layer of ink and printing accuracy. Through the coordinated work of these components, the photocuring module 3 ensures stable energy transmission and efficient photocuring during the printing process, thereby achieving high-quality printing results.

[0052] This embodiment provides a high-efficiency photopolymerization molding method, which includes the following steps: After the electric push rod 26 under the molding cylinder moves the printing platform 21 to the printing plane through the piston 25, the drive motor 42 drives the first scraper assembly 47 to reset to the first station. The peristaltic pump 24 supplies slurry to the feed port 23 through the connecting hose. The drive motor 42 drives the first scraper assembly 47 mounted on the scraper shaft 46 to rotate 180° through the synchronous belt 45. During this period, the first scraper assembly 47 scrapes the slurry on the printing plane onto the printing platform 21 of the first molding cylinder 22 for photopolymerization. The peristaltic pump 24 then supplies slurry to the feed port 23 through the connecting hose. The first scraper assembly 47 rotates another 180°. At this time, the first scraper assembly 47 spreads the slurry onto the printing platform 21 of the second molding cylinder for photopolymerization. Then, the excess slurry is scraped back to the feed port 23. The second scraper assembly 47 scrapes the slurry at the feed port 23 onto the printing platform 21 of the first molding cylinder 22 for photopolymerization. After entering the circulation, during one revolution of the scraper shaft 46, the two layers of slurry in the two forming cylinders are photocured and the excess slurry is recycled, realizing high-speed slurry application and recycling.

[0053] The method includes the following steps:

[0054] S1, the electric push rods 26 of the first forming cylinder and the second forming cylinder move the printing platform 21 to the same height as the printing plane through the piston 25;

[0055] S2, drive motor 42 drives the first scraper assembly 47 to reset to the first station, and the second scraper assembly 47, which is symmetrical to its center, is located at the third station;

[0056] S3, the peristaltic pump 24 supplies slurry to the feed port 23 through the connecting hose;

[0057] S4, drive motor 42 drives the first scraper assembly 47 to rotate and reach the third station via the second station, and the slurry is spread on the printing platform 21; the second scraper assembly 47 then reaches the first station via the fourth station to wait for its turn.

[0058] S5, the photomechanical unit 31 performs photocuring on the paste on the printing platform 21;

[0059] S6, the electric push rod 26 in the first and second forming cylinders drives the printing platform 21 to descend one layer height through the piston 25, and the peristaltic pump 24 supplies the slurry to the feed port 23 again through the connecting pipeline;

[0060] S7, the first scraper assembly 47 reaches the first station via the fourth station and spreads the slurry onto the printing platform 21 of the second forming cylinder; the second scraper assembly 47 then reaches the third station via the second station and spreads the slurry onto the printing platform 21 of the first forming cylinder 22.

[0061] S8, the two optical engines 31 respectively perform photocuring on the paste on the two printing platforms 21;

[0062] S9, repeat S3 to S8 until the model on both printing planes is printed.
