Abstract
Description
Technical Field
[0001] This invention relates to the field of photocurable resin processing technology, specifically to a photocurable resin processing device. Background Technology
[0002] UV-curable resins are composed of resin monomers and prepolymers, containing active functional groups. Under ultraviolet light irradiation, a photosensitizer initiates a polymerization reaction to form an insoluble coating film. They are widely used in environmentally friendly coatings, inks, and other fields. According to existing technology, such as the adjustable stirring range UV-curable resin production reactor described in Chinese patent document CN202121467492.7, the disclosed technical solution utilizes a centralizing ring. The centralizing ring has a certain degree of rotatability, increasing the stability of the stirring rod during rotation, thereby achieving a better stirring effect. The electromechanical cover and heat dissipation mesh on the limiting seat provide some protection for the drive motor. The inner wall of the stirring tank is heated, which, in conjunction with the stirring rod, accelerates the stirring efficiency of the device.
[0003] According to its publicly available technical solutions, existing technologies use stirring to mix the resin monomers and prepolymers added inside. However, the resin monomers have a high viscosity, so when mixed with materials with lower viscosity such as prepolymers, severe stratification occurs, resulting in low mixing efficiency, requiring longer mixing and stirring times, and easily leading to incomplete reactions. On the other hand, conventional photocurable resin processing equipment discharges the same batch of materials after mixing, but the effective reaction and stirring time of raw materials added at different heights and times vary, resulting in certain quality differences in the same batch of finished products. Summary of the Invention

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0026] Please see Figures 1 to 5This invention provides a technical solution: a photocurable resin processing device, comprising a resin processing device body, the resin processing device body including a mixing chamber 1, a reaction vessel 2, a first material preparation tank 3, and a second material preparation tank 4. The reaction vessel 2 is mounted on the top of the mixing chamber 1, and a mixing chamber 6 is mounted on the top of the reaction vessel 2. A power mechanism 5 is installed inside the mixing chamber 6, the reaction vessel 2, and the mixing chamber 1. A motor 9 is mounted on the top of the power mechanism 5 and is fixedly mounted on the top of the mixing chamber 6 using screws. The first material preparation tank 3 and the second material preparation tank 4 are respectively located on both sides of the motor 9, and each of the first material preparation tank 3 and the second material preparation tank 4 has an independent feeding port 8 on its top. An external discharge port 7 is installed at the bottom of the mixing chamber 1, and a turntable 15 is installed inside the mixing chamber 1. The turntable 15 is located at the bottom of the power mechanism 5. When the photocurable resin processing equipment is in use, two material preparation tanks are set at the top. The two main raw materials, resin monomer and prepolymer, are injected into the first material preparation tank 3 and the second material preparation tank 4 respectively. During the subsequent mixing reaction, the raw materials are transported to the bottom inlet mechanism 13 through the feed pipe 12 at the bottom of the two material preparation tanks. The inlet mechanism 13 is connected to the inside of the drive shaft 10, so that the two raw materials can be initially mixed at this position. Then, they flow down along the drive shaft 10 and enter the interior of the turntable 15. After being extruded from the top of the turntable 15, they are stirred and mixed again by multiple stirring blades 17. After a certain reaction time, the finished product after the mixing reaction is discharged outward through the discharge mechanism 14.
[0027] In this embodiment, the power mechanism 5 includes a motor 9 and a drive shaft 10. The top of the drive shaft 10 is connected to the output end of the motor 9. An inlet mechanism 13 is installed on the surface of the drive shaft 10, and an outer feeding pipe 11 is provided at the bottom end of the drive shaft 10. A discharge mechanism 14 is installed on the outer feeding pipe 11, and multiple stirring blades 17 are connected to the side of the outer feeding pipe 11. The shell of the mixing chamber 1 has a conical structure, and each stirring blade 17 is installed inside the mixing chamber 1. Specifically, the drive shaft can be driven by the rotation of the motor 9. The drive shaft 10 rotates, and the outer feeding pipe 11 and inner feeding pipe 22 at the bottom of the drive shaft 10 rotate synchronously. The inlet mechanism 13 remains fixed through the feed pipe 12. The turntable 15 and stirring blade 17 at the bottom rotate with the rotation of the outer feeding pipe 11 and mix the raw materials inside the mixing chamber 1 during the continuous rotation. Since the raw materials are squeezed out from the top, the raw materials above the stirring blade 17 can be fully mixed. After the reaction is completed, they can be automatically discharged from the discharge mechanism 14.
[0028] In this embodiment, both the bottom of the first material tank 3 and the second material tank 4 are provided with feeding pipes 12. Each feeding pipe 12 has an independent guiding mechanism 13 installed at its end. The drive shaft 10 has a hollow internal structure, and its surface has a docking hole 18. The guiding mechanism 13 includes two guiding sleeves 19, each with a filling cavity 21 inside. Both ends of the guiding sleeves 19 have insertion interfaces 20. Each guiding sleeve 19 is connected to the interior of the first material tank 3 or the second material tank 4 via an independent feeding pipe 12. The filling cavity 21 partially seals and blocks the docking hole 18 on the drive shaft 10. The surface of the drive shaft 10 is in contact with the insertion interface 20. A mixing chamber 6 is provided at the top of the reactor 2. Different raw materials flow downwards along the interior of the drive shaft 10, and during the flow, the subsequent raw materials are mixed with the upper material in a spiral propulsion manner. This method improves the mixing efficiency of different materials and makes the mixing more thorough. Specifically, the raw materials flow into the feed pipe 12 through the interior of the first preparation tank 3 or the second preparation tank 4, and then into the filling cavity 21. Inside the cavity, the raw materials come into contact with the rotating drive shaft 10 and enter the interior of the drive shaft 10 along the docking hole 18. The high-viscosity resin monomers are placed inside the top inlet sleeve 19. The low-viscosity prepolymer and other mixed materials are placed inside the bottom inlet sleeve 19. As the drive shaft 10 rotates, the prepolymer mixed materials are mixed from the outside of the resin monomers in a spiral manner, which improves the mixing efficiency.
[0029] In this embodiment, the surface of the turntable 15 is provided with multiple through holes 16, the bottom of the turntable 15 is equipped with supporting balls 25, the bottom of the stirring chamber 1 is provided with a base plate 24, the turntable 15 is partially pressed against the surface of the base plate 24 by the supporting balls 25 at the bottom, the side of the turntable 15 is in contact with the inner wall side of the stirring chamber 1, and the stirring chamber 1 is installed at the bottom. By injecting the raw materials that have completed the initial mixing process into the turntable 15 and extruding them upward along the top of the turntable 15, they can come into contact with the stirring blades 17 above and be stirred. Therefore, the raw materials injected at different times can all receive the same stirring and mixing effect. Specifically, after the resin monomer and prepolymer are mixed, they enter the turntable 15 along the inside of the drive shaft 10 and the inside of the interlayer 28, and are extruded outward from the through holes 16 at the top. The extruded part is stirred by the stirring blades 17 to complete the mixing process, and as the raw materials are injected from the top, the liquid level inside the reactor 2 gradually rises.
[0030] In this embodiment, the discharge mechanism 14 includes a scraper rod 26 and an inner feeding pipe 22. The inner feeding pipe 22 is installed inside the outer feeding pipe 11, and a sandwich 28 is provided between the inner feeding pipe 22 and the outer feeding pipe 11. The inner feeding pipe 22 has a discharge channel 29. The scraper rod 26 has a scraping groove 27 on its surface. The rear end of the scraper rod 26 passes through the surface of the outer feeding pipe 11 and is partially fixedly connected to the inner feeding pipe 22. The bottom of the inner feeding pipe 22 has an inner discharge port 23, which is inserted into the inner side of the outer discharge port 7. The discharge mechanism 14 is installed in the middle of the reactor 2. By rotating the scraper rod 26, the photocurable resin product at the top layer can be fed to the inner layer. The material is transported inside the material pipeline 22. Therefore, with the raw material injection rate remaining constant, the feeding and discharging processes can be realized simultaneously. In the end, the finished products of the same batch are subjected to the same reaction and stirring time, resulting in uniform product quality. After the liquid level inside the reactor 2 rises to contact the scraper rod 26, the top layer of finished product can be scraped into the inner layer feed pipe through the scraper groove 27 on the scraper rod 26. It is then transported to the inner layer feed pipe and finally flows downward along the discharge channel 29, exiting from the inner discharge port 23 at the bottom and entering the outer discharge port 7, thus completing the entire discharge process. The jacket 28 and the discharge channel 29 are separated by the inner layer feed pipeline 22. The jacket 28 is used as a channel to enter the mixing chamber 1, and the two form an independent passage for transportation.
