Description

Technical Field

[0001] This utility model relates to the field of 3D printing filament cooling and shaping technology, specifically to a gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filament. Background Technology

[0002] 3D printing, or rapid prototyping technology, is based on digital model files and uses some adhesive materials to construct objects through printing. The consumables used in printing must first be extruded into filaments in an extruder, and then cooled and shaped by a cooling device to meet the printing requirements.

[0003] However, existing methods for cooling biodegradable PLAPBAT composite 3D printing filaments often involve a single water bath cooling process. While this allows the filament to quickly set, excessively rapid cooling can damage the quality and performance of the filament. Furthermore, water droplets adhere to the filament after cooling, making subsequent winding difficult and hindering its widespread use.

[0004] To address this issue, this application provides a gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filaments. Utility Model Content

[0005] The purpose of this invention is to provide a gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filaments, in order to solve the problems mentioned in the background art, where 3D printing filament cooling and shaping is mostly achieved through a one-time water bath cooling, and water droplets adhere to the filament after cooling. This causes excessively rapid cooling, which damages the quality and performance of the filament, makes subsequent winding difficult, and results in poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filament includes a support assembly, a cooling assembly, and a drying assembly. The support assembly includes a support plate and a motor, with the motor fixedly mounted on the top of the support plate. The cooling assembly is fixedly mounted on the top of the support assembly and includes a cooling water tank, a temperature sensor, and heating tubes. The temperature sensor is fixedly mounted on the bottom of the cooling water tank, and the heating tubes are fixedly mounted on both sides of the cooling water tank. The drying assembly is fixedly mounted inside the support assembly and includes an air duct and a fan, with the fan fixedly mounted inside the air duct.

[0008] A further improvement of this utility model is that: a support leg is fixedly installed at the bottom of the support plate, a drain outlet is fixedly installed at the bottom of the support plate, a valve is fixedly installed inside the drain outlet, and a fixing seat is fixedly installed at the top of the support plate.

[0009] A further improvement of this utility model is that: a first rotating shaft is rotatably installed inside the fixed base, a drive wheel is fixedly installed at one end of the motor, a belt is movably connected to the outside of the drive wheel, and a driven wheel is movably connected to the other end of the belt.

[0010] A further improvement of this utility model is that: the first rotating shaft is fixedly installed inside the driven wheel, the cooling water tank is fixedly installed on the top of the support plate, and a wire slot is provided on the top of the cooling water tank.

[0011] A further improvement of this utility model is that: a second rotating shaft is rotatably installed on the top of the support plate, a water pipe is fixedly installed on the top of the support plate, and a filter screen is fixedly installed on the bottom of the support plate.

[0012] A further improvement of the present invention is that a guide post is fixedly installed on the top of the support plate, a spring is provided on the outside of the guide post, and a cover plate is movably installed on the outside of the guide post.

[0013] A further improvement of this utility model is that the top of the spring is movably connected to the bottom of the cover plate, and the air duct is fixedly installed on the top of the support plate.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filaments. Through the combined action of cooling water tanks and heating pipes, multiple cooling water tanks are set up, and the water in the cooling water tanks is heated to different temperatures through the heating pipes, so that the temperature of the filament can be slowly reduced during cooling, preventing damage to the quality and performance of the filament.

[0016] 2. This utility model provides a gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filaments.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides a gradient cooling and shaping mechanism for biodegradable PLAPBAT composite 3D printing filament, including a support assembly 1, a cooling assembly 2, and a drying assembly 3. The support assembly 1 includes a support plate 10 and a motor 16. The motor 16 is fixedly installed on the top of the support plate 10, and a support leg 11 is fixedly installed on the bottom of the support plate 10. A drain outlet 12 is fixedly installed on the bottom of the support plate 10, and a valve 13 is fixedly installed inside the drain outlet 12. Water in the cooling water tank 20 is discharged through the drain outlet 12 and the valve 13. A fixed base 14 is fixedly installed on the top of the support plate 10. A first rotating shaft 15 is rotatably installed inside the fixed base 14. A drive wheel 17 is fixedly installed at one end of the motor 16. A belt 18 is movably connected to the outside of the drive wheel 17. A driven wheel 19 is movably connected to the other end of the belt 18. The first rotating shaft 15 is fixedly installed inside the driven wheel 19. The motor 16 drives the drive wheel 17 to rotate, and the drive wheel 17 drives the driven wheel 19 and the first rotating shaft 15 to rotate through the belt 18, so that the wire moves and passes through the cooling water tank 20.

[0025] like Figure 5As shown, the cooling component 2 is fixedly installed on the top of the support component 1. The cooling component 2 includes a cooling water tank 20, a temperature sensor 24, and a heating tube 23. The temperature sensor 24 is fixedly installed at the bottom of the cooling water tank 20, and the heating tube 23 is fixedly installed on both sides of the cooling water tank 20. The cooling water tank 20 is fixedly installed on the top of the support plate 10. A wire slot 21 is provided on the top of the cooling water tank 20. A second rotating shaft 22 is rotatably installed on the top of the support plate 10. A water pipe 25 is fixedly installed on the top of the support plate 10. Water is introduced into the cooling water tank 20 through the water pipe 25, and the water in the cooling water tank 20 is heated to different temperatures through the heating tube 23. At the same time, the temperature of the water is detected by the temperature sensor 24. By setting multiple cooling water tanks 20, the temperature of the wire can be reduced slowly during cooling. With the combined action of the cooling water tanks 20 and the heating tubes 23, damage to the quality and performance of the wire is prevented.

[0026] like Figure 2-4 As shown, the drying component 3 is fixedly installed inside the support component 1. The drying component 3 includes an air duct 33 and a fan 31. The fan 31 is fixedly installed inside the air duct 33. A filter screen 30 is fixedly installed at the bottom of the support plate 10. A guide post 35 is fixedly installed at the top of the support plate 10. A spring 32 is provided on the outside of the guide post 35. A cover plate 34 is movably installed on the outside of the guide post 35. The top of the spring 32 is movably connected to the bottom of the cover plate 34. The air duct 33 is fixedly installed at the top of the support plate 10. The cooled wire passes through the top of the air duct 33 and then the cover plate 34 is pressed down. The rotation of the fan 31 blows away the water droplets on the wire. Through the combined action of the fan 31 and the air duct 33, the wire is dried, which is convenient for subsequent winding.

[0027] The working principle of the gradient cooling and shaping mechanism of the biodegradable PLAPBAT composite 3D printing filament will be explained in detail below.

[0028] like Figure 1-5As shown, when using the gradient cooling and shaping mechanism for this biodegradable PLAPBAT composite 3D printing filament, water is introduced into the cooling water tank 20 through the water pipe 25, and the water in the cooling water tank 20 is heated to different temperatures through the heating pipe 23. Simultaneously, the water temperature is detected by the temperature sensor 24. The extruded filament is then passed through the first rotating shaft 15 and the second rotating shaft 22, and then placed into the filament slot 21 on the cooling water tank 20. Under the action of gravity, the filament falls into the cooling water tank 20. The motor 16 drives the drive wheel 17 to rotate, and then the drive wheel 17... 7. The driven wheel 19 and the first rotating shaft 15 are driven by the belt 18 to rotate, so that the wire moves and passes through the cooling water tank 20. By setting multiple cooling water tanks 20, the temperature of the wire can be slowly reduced during cooling. With the combined action of the cooling water tank 20 and the heating pipe 23, damage to the quality and performance of the wire is prevented. The cooled wire is then passed through the top of the air duct 33 and then the cover plate 34 is pressed down. The rotation of the fan 31 blows away the water droplets on the wire. With the combined action of the fan 31 and the air duct 33, the wire is dried, which is convenient for subsequent winding.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
