Description

Technical Field

[0001] This utility model relates to the field of 3D scanning printers, and more specifically, to a real-time 3D scanning printer for dynamic model reconstruction. Background Technology

[0002] With the rapid development of 3D printing technology, the combination of 3D scanning and printing has become an important research direction. While various 3D scanning printers are currently available on the market, most have limitations when handling complex or dynamically changing objects. As industries increasingly demand personalized and customized products, and pursue rapid and accurate modeling and printing of objects, developing a device capable of dynamic model reconstruction and real-time 3D scanning and printing has significant practical implications and application value.

[0003] During long-term operation, the print head of existing 3D scanning printers generates a lot of heat due to continuous operation. If heat dissipation is not timely, the print head temperature may become too high, affecting the performance and stability of the equipment, shortening its service life, or even causing malfunctions.

[0004] Impurities may be present in the printing material. If not filtered, these impurities will enter the nozzle along with the material, causing problems such as filament breakage and blockage during the printing process, which will seriously affect the quality and accuracy of the printed products.

[0005] After printing, impurities may remain on the surface of the nozzle, and these impurities will gradually accumulate and harden. During subsequent printing, they may interfere with the normal extrusion of material, resulting in uneven printed lines, a rough model surface, and severely affecting the printing quality.

[0006] Therefore, we make improvements by proposing a dynamic model reconstruction method for real-time 3D scanning printers. Utility Model Content

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] Dynamic model reconstruction of real-time 3D scanning printers is used to solve the above problems.

[0010] The application is as follows:

[0011] The printer includes a printer body, which has a print head inside and a feed tube in the middle of the print head. A nozzle is fixedly installed at the bottom of the feed tube. A heat dissipation mechanism is provided on one side of the print head. A filter mechanism is provided in the middle of the feed tube. A fixing box is provided outside the nozzle.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. The heat dissipation mechanism, with heat pipes closely attached to the feed tube, rapidly transfers heat generated by the printhead to the heat sink, effectively increasing the heat dissipation area. The cooling fan accelerates airflow, quickly removing heat from the heat sink and effectively reducing the printhead temperature. This prevents printhead overheating from causing performance degradation and shortened lifespan, ensuring the stability of the equipment during long-term operation.

[0021] 2. The use of a filtration mechanism allows for easy assembly and disassembly of the bottom cylinder and connecting cover via a connecting sleeve and threads, facilitating maintenance of the internal filter components. The filter screen at the bottom of the filter cylinder effectively intercepts impurities in the printing material, preventing them from entering the nozzle. Simultaneously, the sealing ring ensures a tight seal at the connection, preventing material leakage. This reduces filament breakage and clogging during printing, significantly improving the quality and accuracy of the printed products.

[0022] 3. Through the use of the cleaning mechanism, the hydraulic rod can drive the cleaning brush to descend to be parallel with the nozzle, and the motor drives the cleaning brush to rotate, which can clean the surface of the nozzle and remove residual impurities on the surface of the nozzle in time, prevent them from accumulating and hardening, avoid impurities interfering with material extrusion during subsequent printing, ensure the uniformity of printed lines and the smoothness of the model surface, and effectively improve the printing effect.

[0038] To address the technical problems in the background section, the following dynamic model reconstruction real-time 3D scanning printer is presented:

[0039] Combination Figure 1 - Figure 6 As shown, the present invention provides a real-time 3D scanning printer for dynamic model reconstruction, comprising a printer body 1, a print head 2 disposed inside the printer body 1, a feed pipe 3 disposed in the middle of the print head 2, and a nozzle 4 fixedly mounted at the bottom end of the feed pipe 3, a heat dissipation mechanism 5 disposed on one side of the print head 2, a filter mechanism 6 disposed in the middle of the feed pipe 3, a fixing box 7 disposed outside the nozzle 4, and a cleaning mechanism 8 disposed inside the fixing box 7; the heat dissipation mechanism 5 includes a heat conduction pipe 501, which is fixedly mounted outside the feed pipe 3, and several heat sinks 502 are fixedly mounted outside the heat conduction pipe 501; a cooling fan 503 is mounted on one side surface of the print head 2.

[0040] In this embodiment: Inside the printer body 1, the printhead 2 is the core working component. The feed tube 3 is used to transport printing material, and the nozzle 4, fixedly installed at the bottom of the feed tube 3, is used to extrude the material to achieve model forming. A heat dissipation mechanism is provided on one side of the printhead 2.

Together with the cooling fan 503 installed on the surface of one side of the printhead 2 to accelerate airflow, the temperature of the printhead 2 can be effectively reduced, avoiding problems such as deterioration of print quality and shortened equipment life due to overheating, and providing a strong guarantee for the stable operation of the printer.

[0041] In a preferred embodiment, the filter mechanism 6 includes a bottom cylinder 601 and a connecting cover 602, and the lower surface of the bottom cylinder 601 and the upper surface of the connecting cover 602 are both connected to the feed pipe 3. A filter cylinder 606 is provided inside the bottom cylinder 601, and a filter screen 607 is fixedly installed at the bottom of the filter cylinder 606.

[0042] In this embodiment, the lower surface of the bottom cylinder 601 and the upper surface of the connecting cover 602 are both tightly connected to the material conveying pipe 3, forming a material conveying channel. The filter cylinder 606 installed inside the bottom cylinder 601 has a filter screen 607 fixedly installed at its bottom, which can filter the flowing printing material, effectively intercept impurities, and ensure the purity of the material entering the nozzle.

[0043] In a preferred embodiment, a groove 604 is provided on the upper surface of the bottom cylinder 601, and a connecting ring 605 is engaged inside the groove 604. The connecting ring 605 is fixedly connected to the filter cylinder 606, and a sealing ring 608 is fixedly installed on the upper surface of the connecting ring 605.

[0044] In this embodiment: the connecting ring 605 engaged in the groove 604 is tightly and fixedly connected to the filter cylinder 606, which realizes the stable installation of the filter cylinder 606 in the bottom cylinder 601 and facilitates subsequent disassembly and cleaning; the sealing ring 608 fixed on the upper surface of the connecting ring 605 can effectively enhance the sealing of the connection and prevent the leakage of printing material.

[0045] In a preferred embodiment, a connecting sleeve 603 is rotatably connected to the outside of the connecting cover 602, and the connecting sleeve 603 is threadedly connected to the top of the bottom cylinder 601.

[0046] In this embodiment, the connecting sleeve 603 and the top of the bottom cylinder 601 are connected by a threaded connection, which is convenient to operate. Simply rotating the connecting sleeve 603 can achieve a tight connection or quick separation between the connecting cover 602 and the bottom cylinder 601, which greatly facilitates the installation, disassembly and replacement of the filter cartridge 606 and improves the efficiency of equipment maintenance.

[0047] In a preferred embodiment, the cleaning mechanism 8 includes a hydraulic rod 801, which is fixedly installed on the top of the fixed box 7. A connecting plate 802 is fixedly installed on the lower surface of the telescopic end of the hydraulic rod 801, and a cleaning brush 803 is fixedly installed on the upper surface of the connecting plate 802.

[0048] In this embodiment: the extension and retraction of the hydraulic rod 801 can drive the cleaning brush 803 to move up and down, so that the cleaning brush 803 is aligned with the spray head 4, which facilitates the subsequent cleaning of the surface of the spray head 4 by rotating the cleaning brush 803.

[0049] In a preferred embodiment, the extension end of the hydraulic rod 801 has an installation groove 804 inside, and a motor 805 is fixedly installed inside the installation groove 804, and the output end of the motor 805 is fixedly connected to the connecting plate 802.

[0050] In this embodiment, the output end of the motor 805 is fixedly connected to the connecting plate 802. When the motor 805 starts, it can drive the connecting plate 802 to rotate, thereby causing the cleaning brush 803 to rotate and clean when it contacts the spray head, which greatly improves the comprehensiveness and effect of cleaning and effectively removes stubborn impurities from the surface of the spray head.

[0051] Specifically, the working principle of this solution is as follows:

[0052] When the printer is working, the printing material is conveyed through the feed tube 3, and the nozzle 4 at the bottom extrudes the material to form the model. During the printing process, the print head 2 generates heat, and the heat dissipation mechanism 5 starts to work. The heat conduction pipe 501 is closely attached to the feed tube 3 to quickly conduct heat, the heat sink 502 increases the heat dissipation area, and the cooling fan 503 accelerates the airflow, effectively reducing the temperature of the print head 2 and ensuring stable operation of the equipment.

[0053] As the printing material flows in the feed tube 3, the filtering mechanism 6 functions. The bottom cylinder 601 and the connecting cover 602 form a feed channel. The filter screen 607 at the bottom of the filter cylinder 606 filters the material, intercepting impurities and ensuring material purity. The connecting ring 605 engages in the groove 604, ensuring a stable installation of the filter cylinder 606 and facilitating disassembly and cleaning. The sealing ring 608 enhances the sealing at the connection. The connecting sleeve 603 is threaded to the top of the bottom cylinder 601, facilitating the installation, disassembly, and replacement of the filter cylinder 606.

[0054] After the nozzle 4 is used, the cleaning mechanism 8 is started. The hydraulic rod 801 extends and retracts, causing the cleaning brush 803 to move up and down, aligning it with the nozzle 4. The motor 805 starts, causing the connecting plate 802 to rotate, which in turn causes the cleaning brush 803 to rotate and clean the surface of the nozzle 4, effectively removing stubborn impurities.

[0055] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0056] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
