[0002] Photosensitive resin is a polymer material that can rapidly undergo a polymerization reaction under the irradiation of light of a specific wavelength. It is widely used in 3D printing, microelectronics and other fields. In order to improve the purity of the resin to ensure the mechanical properties, molding accuracy and chemical stability of the subsequent products, and to avoid printing defects or performance degradation caused by impurities, a photosensitive resin purification device is needed.

[0003] A photosensitive resin purification device is a specialized piece of equipment used to remove impurities from photosensitive resin and improve resin purity. Traditional photosensitive resin purification devices often suffer from problems such as filter overload and impurity residue due to excessive material discharge, and wasted time due to insufficient material discharge, resulting in reduced production efficiency. Furthermore, the unstable purification effect can easily affect the quality of the final product. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photosensitive resin purification device, comprising a base plate, a support frame fixedly connected to the upper surface of the base plate, a first motor and a fixed column fixedly connected to the upper surface of the support frame, a first connecting shaft fixedly disposed at the output end of the first motor, the outer wall of the first connecting shaft rotatably connected through the support frame, a first bevel gear fixedly connected to the outer wall of the first connecting shaft, a connecting block rotatably connected to the outer wall of the first connecting shaft, a second bevel gear meshing with the tooth end of the first bevel gear, the interior of the second bevel gear rotatably connected to the outer wall of the connecting block, a threaded rod fixedly connected to the outer wall of the second bevel gear, a slider threadedly connected to the outer wall of the threaded rod, a discharge box rotatably connected to the outer wall of the slider, the interior of the discharge box rotatably connected to the outer wall of the fixed column, and a coarse filter assembly disposed on the outer wall of the discharge box.

[0010] Preferably, a second motor is fixedly connected to the upper surface of the base plate, and a second connecting shaft is fixedly provided at the output end of the second motor. The outer wall of the second connecting shaft is rotatably connected to the inside of the gearbox.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the first motor drives the first connecting shaft to rotate within the support frame. The first connecting shaft drives the bevel gear to rotate, which in turn drives the threaded rod to rotate, causing the slider to move up and down. The slider drives the pouring box to rotate on its outer wall relative to the fixed column. Since the pouring box rotates with the top of the fixed column as the base point, it drives the threaded rod and bevel gear to rotate, which in turn causes the connecting block to rotate on the outer wall of the first connecting shaft, thus playing the role of pouring material into the filter barrel.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model provides a photosensitive resin purification device, including a base plate 1, a support frame 2 fixedly connected to the upper surface of the base plate 1, a first motor 3 and a fixed column 11 fixedly connected to the upper surface of the support frame 2, a first connecting shaft 4 fixedly provided at the output end of the first motor 3, the outer wall of the first connecting shaft 4 being rotatably connected through the support frame 2, a first bevel gear 5 fixedly connected to the outer wall of the first connecting shaft 4, a connecting block 7 rotatably connected to the outer wall of the first connecting shaft 4, a second bevel gear 6 meshing with the tooth end of the first bevel gear 5, the interior of the second bevel gear 6 being rotatably connected to the outer wall of the connecting block 7, a threaded rod 8 fixedly connected to the outer wall of the second bevel gear 6, a slider 9 threadedly connected to the outer wall of the threaded rod 8, a pouring box 10 rotatably connected to the outer wall of the slider 9, the interior of the pouring box 10 being rotatably connected to the outer wall of the fixed column 11, and a coarse filter assembly provided on the outer wall of the pouring box 10.

[0026] Specifically, the first motor 3 drives the first connecting shaft 4 to rotate inside the support frame 2, providing power to the entire pouring mechanism and initiating the quantitative pouring process. The first connecting shaft 4 drives the first bevel gear 5 to rotate, transmitting power to the bevel gear transmission system and changing the direction of power. This, in turn, drives the second bevel gear 6 to rotate, converting vertical and horizontal power and driving the threaded rod 8. The second bevel gear 6 drives the threaded rod 8 to rotate, which in turn drives the slider 9 to move up and down, converting rotational motion into linear motion and driving the slider 9 to move. The slider 9 drives the pouring box 10 to rotate on the outer walls of both the slider 9 and the fixed column 11, changing the tilt angle of the pouring box 10 and controlling the pouring speed and quantity. Since the pouring box 10 is connected to the fixed column 11... The top of the feed box 10 rotates as a base point, which in turn drives the threaded rod 8 and the second bevel gear 6 to rotate, forming a coordinated movement of the mechanism. This achieves the effect of stable control of the feeding process. The rotation of the feed box 10 further drives the connecting block 7 to rotate on the outer wall of the first connecting shaft 4, enhancing the integrity and stability of the mechanism and ensuring smooth feeding. Through the coordinated action of the above mechanisms, the filter barrel 13 is fed quantitatively, achieving precise control of the feeding amount, improving production efficiency and product quality. A protective box is provided on the upper surface of the support frame 2. The first connecting shaft 4 rotates through the inside of the protective box. The inside of the protective box has enough space for the first bevel gear 5 and the second bevel gear 6 to rotate. A sliding groove is provided inside the protective box for the threaded rod 8 to slide. A limit block is provided at the top of the threaded rod 8 to prevent the slider 9 from disengaging from the threaded rod 8 and affecting the operation of the device.

[0027] Reference Figure 1 and Figure 5The coarse filtration assembly includes a U-shaped plate 12, the outer wall of the discharge box 10 is slidably connected to the inner wall of the U-shaped plate 12, the outer wall of the U-shaped plate 12 is fixedly connected to a filter barrel 13, the inner wall of the filter barrel 13 is provided with a coarse filter screen 14, and the bottom end of the filter barrel 13 is fixedly connected to the outer wall of the support frame 2.

[0028] Specifically, the U-shaped plate 12 facilitates the pouring of photosensitive resin into the filter tank 13, acting as a limit for the pouring box 10. This ensures stable resin entry into the filter tank 13 and prevents resin spillage. The coarse filter screen 14 inside the filter tank 13 intercepts and filters larger impurities in the resin, preventing large particles from clogging subsequent filtration components. This achieves initial resin purification and ensures smooth subsequent fine filtration.

[0029] Reference Figure 2 , Figure 5 and Figure 6 A cylinder 22 is fixedly connected to the bottom of the filter barrel 13. A gearbox 19 is fixedly connected to the outer wall of the cylinder 22, and a filter membrane 23 is fixedly connected to the inner wall of the cylinder 22. A feed pipe 24, a discharge valve 26, and a drain valve 27 are connected through the inside of the cylinder 22. An air inlet valve 25 is fixedly connected through the inside of the feed pipe 24, and the outer wall of the feed pipe 24 is fixedly connected through the inside of the filter barrel 13. The outer wall of the feed pipe 24 is fixedly connected through the inside of the filter membrane 23.

[0030] Specifically, the feed pipe 24 serves to guide the coarsely filtered resin into the filter membrane 23, establishing a material channel between coarse and fine filtration. This ensures the resin enters the fine filtration stage in an orderly manner. Opening the air inlet valve 25 introduces pressurized nitrogen into the filtration system, creating a stable pressure on the resin surface. This propels the resin smoothly through the filter membrane 23, improving filtration efficiency. Starting the second motor 15 drives the second connecting shaft 16 to rotate within the gearbox 19, transmitting motor power to the gear transmission unit. The first gear 17 rotates synchronously with the second gear 18, which in turn drives the second gear 18 to rotate. This further transmits power and drives the second gear 18 to rotate. The rotation of the first gear 17 drives the second gear 18 to rotate, thus giving the rotating shaft 20 rotational power. The rotation of the second gear 18 drives the rotating shaft 20 to rotate inside the cylinder 22, transmitting gear power to the scraper 21 and making the scraper 21 move synchronously with the rotating shaft 20.

[0031] Reference Figure 2 and Figure 6A second motor 15 is fixedly connected to the upper surface of the base plate 1. A second connecting shaft 16 is fixedly installed at the output end of the second motor 15. The outer wall of the second connecting shaft 16 is rotatably connected to the inside of the gearbox 19. A first gear 17 is fixedly connected to the outer wall of the second connecting shaft 16. The teeth of the first gear 17 are meshed with a second gear 18. A rotating shaft 20 is fixedly connected to the inside of the second gear 18. The outer wall of the rotating shaft 20 is rotatably connected to the inside of the cylinder 22. A scraper 21 is fixedly connected to the outer wall of the rotating shaft 20. The outer wall of the scraper 21 is slidably connected to the inner wall of the filter membrane 23.

[0032] Specifically, the rotation of the rotating shaft 20 drives the scraper 21 to slowly rotate along the filter membrane surface. This scrapes away impurities adhering to the filter membrane surface and also acts as a stirring blade to agitate the resin, preventing filter membrane clogging and improving pressure filtration efficiency. The impurities scraped off by the scraper 21 are discharged with the wastewater through the drain valve 27, promptly cleaning up filtration waste and preventing impurity accumulation from affecting the filtration effect. This ensures the continuous and stable operation of the filtration system. The discharge valve 26 discharges the purified resin after fine filtration, completing the entire resin filtration process and providing qualified resin for subsequent production. The photosensitive resin material works by protecting the transmission components such as the first gear 17 and the second gear 18 through the gearbox 19, which prevents impurities from entering the gear meshing area and reduces component wear, thereby extending the service life of the transmission components and ensuring stable power transmission. The cylinder 22 provides rotational support for the rotating shaft 20, which limits the movement trajectory of the rotating shaft 20 and prevents the rotating shaft 20 from deviating, which would cause the scraper 21 to not be able to accurately act on the filter membrane. This ensures that the scraper 21 stably removes impurities and stirs the resin. The resin needs to be heated at a low temperature during filtration. If the temperature is too high, the resin will become increasingly viscous, and if the temperature is too low, the resin will become less fluid.

[0033] Working principle: When the device is needed, the first motor 3 is started first. The first motor 3 drives the first connecting shaft 4 to rotate inside the support frame 2. The first connecting shaft 4 drives the first bevel gear 5 to rotate, which in turn drives the second bevel gear 6 to rotate. The second bevel gear 6 drives the threaded rod 8 to rotate, which in turn drives the slider 9 to move up and down. The slider 9 drives the pouring box 10 to rotate on the outer walls of the slider 9 and the fixed column 11 respectively. Since the pouring box 10 rotates with the top of the fixed column 11 as the base point, the pouring box 10 drives the threaded rod 8 and the second bevel gear 6 to rotate, which in turn drives the connecting block 7 to rotate on the outer wall of the first connecting shaft 4, thus playing the role of pouring material into the filter barrel 13 and achieving the effect of quantitative pouring.

[0034] With the U-shaped plate 12 connected, photosensitive resin is poured into the filter tank 13. Larger impurities in the resin are filtered through the coarse filter screen 14. The coarsely filtered resin then enters the filter membrane 23 through the feed pipe 24. Simultaneously, the air inlet valve 25 is opened to introduce pressurized nitrogen. The gas creates pressure on the resin surface, smoothly pushing the resin through and onto the filter membrane 23. At this time, the second motor 15 is started, driving the second connecting shaft 16 to rotate inside the gearbox 19. The second connecting shaft 16 drives the first gear 17 to rotate, which in turn drives the second gear 18 to rotate. 18 drives the rotating shaft 20 to rotate inside the cylinder 22, which in turn drives the scraper 21 to rotate. The scraper 21 rotates slowly along the surface of the filter membrane to scrape off the adhering impurities. The scraped impurities are discharged with the sewage through the drain valve 27, and the filtered resin is discharged through the discharge valve 26. The scraper 21 can also act as a stirring blade to stir the resin and improve the efficiency of pressure filtration. After the resin filtration is completed, the coarse filter screen 14 is removed and cleaned in time. Water is injected into the filter tank 13, and the second motor 15 is started. The above operation is repeated to clean the cylinder 22 and the filter membrane 23 to prevent the resin from solidifying and affecting the next use of the device.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
