Technical Field

[0001] The utility model relates to the technical field of 3D printing scraping devices, in particular to a 3D printing scraping device for traffic engineering accessory components. Background Technique

[0002] With the rapid development of the construction engineering field in China, the scope of 3D printing technology is also more extensive. In recent years, 3D printing technology has been greatly promoted and applied in fields such as traffic engineering. However, the quality of 3D printing of traffic engineering accessory components cannot be guaranteed.

[0003] In the prior art, during the 3D printing process of traditional traffic engineering accessory components, a scraper is usually used to closely adhere to the side surface of the extrudate for real-time trimming and leveling. In order to solve the problems of poor surface flatness caused by uneven extrusion and irregular edges caused by material shrinkage. However, although the existing 3D printing scraping device can improve the flatness of the extrudate and the adhesion between layers, in order to ensure no deviation during the printing process, it usually welds the scraper to the bottom of the printing nozzle, and the printing nozzle and the feeding cylinder are fixedly connected. This makes it difficult to effectively replace the printing nozzle when replacing different printing components, resulting in poor adaptability of the 3D printing scraping device, thereby affecting its use effect.

[0004] Therefore, there is a need for a 3D printing scraping device for traffic engineering accessory components, in which the printing nozzle cannot be effectively replaced, resulting in the scraper being unable to achieve an effective leveling effect when replacing different printing components, thus affecting the low adaptability of the 3D printing scraping device. Content of the Utility Model

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] For the 3D printing scraping device of traffic engineering accessory components proposed by the present utility model, by rotating the printing nozzle to drive the threading ring to gradually disengage from the threaded groove, it makes the replacement of the printing nozzle more convenient, thereby improving the adaptability of the device.

[0023] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0024] Embodiment 1: Please refer to Figures 1 to 7 , the present utility model provides a technical solution: A 3D printing scraping device for traffic engineering accessory components, including a silo 1, the silo 1 is made of stainless steel, with an upper diameter of 150 mm and a lower diameter of 50 mm. A material conveying cylinder 2 is installed at the bottom of the silo 1. The material conveying cylinder 2 has a diameter of 50 mm and is made of stainless steel. A screw agitator 5 is installed inside the material conveying cylinder 2. A printing nozzle 4 is provided at the bottom of the material conveying cylinder 2. The size specifications of the printing nozzle 4 are three types: φ10mm, φ15mm, and φ20mm. A threading ring 6 is installed above the printing nozzle 4. A scraper 7 is installed on the inner wall of the printing nozzle 4. A threaded groove 10 is opened at the bottom of the material conveying cylinder 2; the threading ring 6 is threadedly connected to the inner wall of the threaded groove 10.

[0025] When different printing components need to be replaced, at this time, rotate the printing nozzle 4. Since the threading ring 6 is installed at the top of the printing nozzle 4 and the threading ring 6 is threadedly connected to the inner wall of the threaded groove 10, when rotating the printing nozzle 4 at this time, it will drive the threading ring 6 to gradually move downward. At this time, the printing nozzle 4 can be replaced, and the scraper 7 can be removed and replaced together. After completion, reset the printing nozzle 4 of different sizes, and insert the threading ring 6 into the inner wall of the threaded groove 10. At the same time, reverse rotation drives the threading ring 6 to gradually rise along the inner wall of the threaded groove 10, so as to facilitate the replacement of the printing nozzle 4, enable the leveling device to meet the requirements of different printing components, and further improve the leveling effect of the scraper 7.

[0026] Embodiment 2: On the basis of Embodiment 1, in order to enhance the stability of the installation between the printing nozzle 4 and the material feeding cylinder 2, a fixing ring 3 is installed on the outer side of the lower part of the material feeding cylinder 2. A plugging groove 9 is formed at the bottom of the fixing ring 3. Connecting blocks 8 are installed on both the left and right sides of the printing nozzle 4, and rubber columns 14 are installed on the tops of the connecting blocks 8; the rubber columns 14 are plugged into the inner wall of the plugging groove 9, and when the rubber columns 14 are pushed by the connecting blocks 8 to the inner wall of the plugging groove 9, they are in a state of extrusion deformation. Thus, when installing the connecting blocks 8, the rubber columns 14 are driven to be plugged into the inner wall of the plugging groove 9 and are clamped with it; the upper parts of the connecting blocks 8 are plugged into the inner wall of the plugging groove 9, and when the printing nozzle 4 is installed with the material feeding cylinder 2 through the threading ring 6, the connecting blocks 8 rotate along the inner wall of the plugging groove 9 with the center of the threading ring 6 as the axis. Thus, it will not affect the normal installation of the printing nozzle 4 and improves its installation stability, preventing the threading ring 6 from loosening due to vibration caused by the rotation of the screw agitator 5.

[0027] When different printing components need to be replaced, at this time, rotate the printing nozzle 4, and drive the connecting blocks 8 on both sides of it to rotate along the inner wall of the plugging groove 9, and at the same time drive the rubber columns 14 to rotate along the inner ring wall of the plugging groove 9. Since the threading ring 6 is installed at the top of the printing nozzle 4 and the threading ring 6 is threadedly connected to the inner wall of the thread groove 10, when rotating the printing nozzle 4 at this time, it will drive the threading ring 6 to gradually move downward, and at the same time drive the connecting blocks 8 to gradually disengage from the plugging groove 9. When the threading ring 6 rotates downward a certain distance, at this time, the rubber column 14 will be driven by the downward movement of the printing nozzle 4 and make it descend in a state of being pushed, and then gradually disengage from the plugging groove 9. At this time, the printing nozzle 4 can be replaced, and the scraper 7 can be removed and replaced together. After completion, reset the printing nozzle 4 of different sizes, and plug the threading ring 6 into the inner wall of the thread groove 10, and at the same time reverse-rotate to drive the threading ring 6 to gradually rise along the inner wall of the thread groove 10, and at the same time drive the connecting blocks 8 to be plugged into the inner wall of the plugging groove 9 and rotate along the inner wall of the plugging groove 9. When the threading ring 6 is completely reset, at this time, the rubber column 14 will be pushed by the connecting block 8 and plugged into the inner ring groove of the plugging groove 9 and is plugged with it at the same time. Thus, the rubber column 14 is used to increase the firmness of the installation between the connecting block 8 and the fixing ring 3, and the rubber column 14 can also disperse a certain amount of vibration, thereby improving the use effect of the printing nozzle 4.

[0028] Embodiment 3: On the basis of Embodiment 2, in order to reduce the vibration transmission caused by the rotation of the spiral stirrer 5 and further improve the stability of the installation of the threading ring 6, a chute 11 is provided on the upper side of the fixed ring 3, and a rubber ring 12 is slidably connected to the inner wall of the chute 11. A plurality of rubber balls 13 are installed on the bottom wall of the chute 11; the tops of the plurality of rubber balls 13 are all in contact with the bottom of the rubber ring 12, so as to utilize the cooperation between the rubber balls 13 and the rubber ring 12 to disperse the vibration generated by the spiral stirrer 5, thereby improving the stability of the installation of the printing nozzle 4 and preventing the threading ring 6 from loosening due to vibration.

[0029] During use, first place the extruded material inside the material bin 1, then start the spiral stirrer 5 to drive the extruded material to be conveyed downward and extrude it through the printing nozzle 4. At this time, since a scraper 7 is installed on the inner wall of the printing nozzle 4, the extruded material is extruded from the left side of the printing nozzle 4, and at the same time, the side of the extruded material is leveled by the scraper 7, thereby reducing the phenomenon of wrinkles on the side of the component. At the same time, using the elasticity of the rubber balls 13, the vibration during the use of the spiral stirrer 5 is reduced, and the vibration is dispersed through the rubber ring 12, thereby reducing the impact of these vibrations on the printing nozzle 4, so as to prevent the printing nozzle 4 from rotating due to vibration, resulting in the threading ring 6 gradually detaching from the thread groove 10, thereby improving the stability of the installation of the printing nozzle 4 and improving the use effect of the leveling device.

[0030] During actual use, when different printing components need to be replaced, at this time, rotate the printing nozzle 4 and drive the connecting blocks 8 on both sides of it to rotate along the inner wall of the insertion slot 9, and at the same time drive the rubber column 14 to rotate along the inner ring wall of the insertion slot 9. Since a threading ring 6 is installed at the top of the printing nozzle 4 and the threading ring 6 is threadedly connected to the inner wall of the thread groove 10, when the printing nozzle 4 is rotated at this time, the threading ring 6 will be driven to gradually move downward, and at the same time drive the connecting blocks 8 to gradually disengage from the insertion slot 9. When the threading ring 6 rotates downward by a certain distance, at this time, the rubber column 14 will be driven by the downward movement of the printing nozzle 4 and let it descend in a squeezed state, and then gradually disengage from the insertion slot 9. At this time, the printing nozzle 4 can be replaced, and the scraper 7 can be removed and replaced together. After completion, reset the printing nozzle 4 of different sizes, insert the threading ring 6 into the inner wall of the thread groove 10, and at the same time reverse it to drive the threading ring 6 to gradually rise along the inner wall of the thread groove 10, and at the same time drive the connecting blocks 8 to be inserted into the inner wall of the insertion slot 9 and rotate along the inner wall of the insertion slot 9. When the threading ring 6 is completely reset, at this time, the rubber column 14 will be pushed by the connecting blocks 8 and inserted into the inner ring groove of the insertion slot 9 and inserted into it at the same time, so as to utilize the rubber column 14 to increase the firmness of the installation between the connecting block 8 and the fixed ring 3, and at the same time, the rubber column 14 can also disperse a certain amount of vibration, thereby improving the use effect of the printing nozzle 4;

[0031] When in use, the extrudate is first placed inside the silo 1, and then the spiral agitator 5 is started to drive the extrudate to be transported downward and extruded through the print head 4. At this time, since the inner wall of the print head 4 is installed with a scraper 7, the extrudate is extruded through the left side of the print head 4, and the scraper 7 is used to smooth the side of the extrudate, thereby reducing the phenomenon of wrinkles on the side of the component. At the same time, the elastic force of the rubber ball 13 is used to slow down the vibration of the spiral agitator 5 during use, and the vibration is dispersed through the rubber ring 12, thereby slowing down the impact of these vibrations on the print head 4, so as to prevent the print head 4 from rotating due to vibration, causing the threaded ring 6 to gradually disengage from the thread groove 10, thereby improving the stability of the installation of the print head 4 and improving the use effect of the smoothing device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
