Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution for a product molding cooling device for medical 3D printing: A product molding cooling device for medical 3D printing includes: a frame 1, an inner plate 2 inside the frame 1, the inner plate 2 being bent, a material inlet 9 being formed between the upper end of the inner plate 2 and the frame 1, and a material outlet 10 being formed between the lower end of the inner plate 2 and the frame 1; two spaced horizontal plates 3 are fixedly installed inside the frame 1, with the inner plate 2 located between the two horizontal plates 3; fans 4 facing the inner plate 2 are installed on each of the horizontal plates 3. Multiple equally spaced mounting holes 12 are provided on both sides of the frame 1.

[0024] The frame 1 is installed at the discharge port of the 3D printer. The product falls onto the inner plate 2 through the feed inlet 9 and slides into the frame 1 through the inner plate 2. The product is cooled by the fans 4 on both sides of the product. The airflow generated by the fans 4 can cool the two sides of the workpiece and quickly remove the heat from the surface of the workpiece to achieve rapid cooling.

[0025] The inner plate 2 has an opening 5, within which are arranged multiple equidistant rotating rollers 6. The upper ends of the rotating rollers 6 extend beyond the opening 5, and each rotating roller 6 is fixedly connected to a connecting shaft 7. The ends of the connecting shafts 7 are rotatably mounted within the opening 5, and each end of the connecting shaft 7 is fixedly mounted with a transmission wheel 8. The inner plate 2 is provided with a drive mechanism to drive the multiple transmission wheels 8 to rotate synchronously. The drive mechanism includes a support plate 11, which is fixedly mounted on the bottom of the inner plate 2. Two spaced rotating shafts 13 are rotatably mounted on the support plate 11, and each rotating shaft 13 is fixedly mounted with a pulley 14. A belt 15 is installed between the two pulleys 14, and the upper end of the belt 15 contacts the multiple transmission wheels 8. The belt 15 can drive the multiple transmission wheels 8 to rotate through friction. The drive mechanism also includes a servo motor 16, which is fixedly mounted on the support plate 11. The output shaft of the servo motor 16 passes through the support plate 11 and is fixedly connected to one side of the rotating shaft 13. The surface of the roller 6 is provided with anti-slip texture, which can increase the friction between the roller 6 and the workpiece and prevent the workpiece from slipping. The inner plate 2 is polished, which can make the workpiece slide more smoothly on the inner plate 2.

[0026] When the workpiece slides to the lower end of the inner plate 2, the servo motor 16 drives the rotating shaft 13 to rotate, which in turn drives the belt 15. The belt 15 drives multiple transmission wheels 8 to rotate synchronously and in the same direction. The transmission wheels 8, rotating rollers 6, and connecting shaft 7 rotate synchronously, and the multiple rotating rollers 6 rotate synchronously in the same direction. The rotating rollers 6 can move the workpiece on them to one side, thereby driving the workpiece to be discharged from the discharge outlet 10. During the movement of the workpiece, the fans 4 on the upper and lower sides can provide comprehensive cooling to both sides of the workpiece. This application can automatically perform the workpiece entry and exit operations, reduce manual intervention in the transfer process, reduce labor costs, and improve cooling efficiency.

[0027] A temperature display device 17 is installed on the frame 1, and the temperature probe of the temperature display device 17 is located inside the frame 1. The temperature display device 17 measures the internal temperature of the frame 1. When the internal temperature of the frame 1 is too high, the cooling of the workpiece is stopped. Limiting plates 18 are fixedly installed on both sides of the inner plate 2. The limiting plates 18 on both sides limit the workpiece on the inner plate 2 to prevent the workpiece from falling off the sides of the inner plate 2.

[0028] The working principle of this utility model is as follows: The frame 1 is installed at the discharge port of the 3D printer. The product falls onto the inner plate 2 through the feed inlet 9 and slides into the frame 1 through the inner plate 2. The product is cooled by fans 4 on both sides of the product. The airflow generated by the fans 4 can cool the sides of the workpiece, quickly removing heat from the surface of the workpiece and achieving rapid cooling. When the workpiece slides to the lower end of the inner plate 2, the servo motor 16 drives the rotating shaft 13 to rotate, which in turn drives the belt 15. The belt 15 drives multiple transmission wheels 8 to rotate synchronously and in the same direction. The transmission wheels 8, rotating rollers 6, and connecting shaft 7 rotate synchronously, and the multiple rotating rollers 6 rotate synchronously in the same direction. The rotating rollers 6 can move the workpiece on them to one side, thereby driving the workpiece to be discharged from the discharge outlet 10. During the movement of the workpiece, the fans 4 on the upper and lower sides can provide comprehensive cooling to both sides of the workpiece. This application can automatically perform the workpiece entry and exit operations, reduce manual intervention in the transfer process, reduce labor costs, and improve cooling efficiency.
