Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printers, and specifically relates to a 3D printer with a consumable material guiding function. Background Art

[0002] There are three common 3D printing technologies, namely FDM technology, SLS technology and SLA technology. Among the above three technologies, the 3D printer with FDM technology needs to transfer the hot-melt solid filament to the print head through the filament guide bracket, and the filament is heated to a molten state through the print head; then, the molten filament can be squeezed out through the nozzle, and the filament is cooled and solidified to be stacked layer by layer, and finally stacked into the required model under the control of the computer.

[0003] In existing 3D printing equipment, one end of the filament is generally wound on a winding reel, and the other end of the filament is naturally connected to the feed end of the nozzle extrusion mechanism. The filament is unwound through the winding reel to transfer the filament to the nozzle extrusion mechanism. The nozzle extrusion mechanism moves during the printing process, so it will drive the filament to swing randomly, causing the filament to swing with a large amplitude, which is easy to cause the filament to break. In the process of twisting the filament, there will be a large friction between the filament bracket and the filament, which is easy to cause the filament to wear, thereby affecting the smoothness of the filament entering the feed end, and then affecting the printing efficiency and printing stability.

[0028] The guide mechanism 20 is effectively driven by the driving mechanism 40 , and the consumable assembly 30 is effectively driven by the guide mechanism 20 to follow the movement of the print head 13 for guide adjustment.

[0029] It should be noted that the level monitor 23 is electrically connected to the driving source in the second driving assembly 42, and can effectively drive the second driving assembly 42 to adjust the second guide block 26 and the consumable assembly 30 through the detection of the level monitor 23. Among them, the adjustment source in the axial adjustment assembly 12 is electrically connected to the driving source in the first driving assembly 41, and can control the driving source in the first driving assembly 41 to work synchronously, and effectively drive the first guide block 22 at the output end of the first driving assembly 41 to perform guiding work.

[0030] In this embodiment, the 3D printer body 10 can effectively complete the printing work. Among them, the frame 11 is used as an effective structural support to make the printing work smoother. The axial adjustment component 12 is arranged on the frame 11 to effectively drive the print head 13, so that the print head 13 completes the adjustment in the horizontal direction. By fixing the print head 13 for extruding the consumables on the axial adjustment component 12, the consumables can be effectively stacked and formed.

By fixing the support block 24 on the connecting plate 21, the support and fixation of the guide rod 25 can be effectively completed. Among them, a guide rod 25 for supporting and adjusting the consumable assembly 30 is rotatably provided in the support block 24. By slidingly providing a second guide block 26 on the guide rod 25, the second guide block 26 can ensure that the guide rod 25 moves and adjusts the consumable assembly 30 while rotating. Among them, the consumable assembly 30 is slidably provided on the second guide block 26, which can ensure that the guide rod 25 can effectively drive the consumable assembly 30 to move accurately along the trajectory, and at the same time can ensure the accurate guidance and use of the consumables during the printing process. The driving mechanism 40 is used to realize the movement of the guide mechanism 20. Specifically, the driving mechanism 40 includes a first driving assembly 41 fixed on the frame 11 for driving the first guide block 22 for guiding adjustment. The first driving assembly 41 is rotatably connected to the first guide block 22, so that the first guide block 22 can be effectively guided and controlled. The driving mechanism 40 also includes a second driving assembly 42 fixed on the connecting plate 21 for driving the second guide block 26 for guiding adjustment.

[0031] Preferably, the consumable assembly 30 includes a consumable tray 31 slidably disposed on the second guide block 26. By winding the printing consumables 32 on the consumable tray 31, the printing consumables can be effectively collected and used.

Among them, one end of the printing consumables 32 passes through the first guide block 22 and is connected to the print head 13. The first guide block 22 can ensure that the printing consumables 32 are driven to move, and ensure that they can be smoothly transported to the print head 13, thereby realizing the transportation and use of the consumables during the printing process.

[0032] like Figure 2 As shown, the first guide block 22 is provided with an adjustment hole 221 for driving and adjusting the first guide block 22. The first guide block 22 is also provided with a guide groove 222 for guiding and transmitting the printing consumables 32. The printing consumables 32 are arranged in the guide groove 222, so that the transmission of the printing consumables 32 can be effectively completed.

[0033] Preferably, the first drive assembly 41 includes a mounting block 411 fixed on the frame 11 for supporting and fixing the drive source. By fixing the first drive motor 412 on the mounting block 411, the driving work of the first drive assembly 41 can be effectively completed, and the first guide block 22 can be effectively driven to perform guide adjustment.

[0034] like Figure 3 As shown, the second guide block 26 includes a guide bearing 261 slidably disposed on the guide rod 25 for ensuring that the consumable assembly 30 can effectively rotate. A driving plate 262 for driving the guide bearing 261 and the consumable assembly 30 to move is fixedly connected above the guide bearing 261. By providing a driving hole 263 on the driving plate 262, the driving plate 262 can be effectively connected to the second driving assembly 42, so that the second driving assembly 42 can effectively drive the second guide block 26 to perform the guiding work.

By fixing the second drive motor 422 on the fixed block 421, the driving work of the second drive assembly 42 can be effectively completed, so that the second drive assembly 42 can effectively drive the second guide block 26 for guiding adjustment. By fixing a second guide screw 423 for transmitting driving force to the output end of the second drive motor 422, the second guide block 26 can be effectively driven. Among them, the other end of the second guide screw 423 is rotatably provided with a placement plate 424 for supporting and placing the second guide screw 423, and the placement plate 424 can effectively ensure that the second guide screw 423 will not shake or deviate during transmission. It should be noted that the second guide screw 423 is threadedly connected to the drive hole 263, which can effectively control and adjust the second guide block 26.

[0036] The working principle of the utility model is as follows: when printing, by sleeve-mounting the consumable assembly 30 on the second guide block 26, when printing, as the print head 13 moves, the first driving assembly 41 located on the frame 11 can be effectively driven to start, and the first driving assembly 41 drives the first guide block 22 to move, so that the guide groove 222 in the first guide block 22 drives the printing consumables 32 to move, so that the printing consumables 32 are always on the same horizontal plane as the print head 13, and will not shake or fold significantly. Among them, when the first guide block 22 drives the printing consumables 32 to move, the level monitor 23 in the guide mechanism 20 will detect the printing consumables 32 from the consumable tray 31 to the first guide block 22. By electrically connecting the level monitor 23 to the second drive motor 422, the second drive assembly 42 can be controlled to effectively drive the second guide block 26 to move, thereby driving the consumable tray 31 to move, so that the printing consumables 32 on the consumable tray 31 and the printing consumables 32 in the first guide block 22 are in the same horizontal plane, thereby guiding the printing consumables 32. The drive mechanism 40 can effectively drive the guide mechanism 20 to adjust the guide as the print head 13 moves, ensuring that the consumables will not break.
