[0002] There are three common 3D printing technologies, which are FDM technology, SLS technology and SLA technology. Among the above three technologies, the 3D printer of FDM technology needs to transmit the hot-melt solid filament consumables to the print head through the consumable guide support, and heat the consumables to the molten state through the print head. Then, the molten consumables can be extruded through the nozzle, so that the consumables cool and solidify layer by layer to form the required model under the control of the computer.
[0003] In the existing 3D printing equipment, the consumables are generally wound on the winding disc, and the consumables are connected with the feeding end of the nozzle extrusion mechanism to transmit the consumables to the nozzle extrusion mechanism. Since the nozzle extrusion mechanism moves during printing, it will cause the consumables to swing randomly, resulting in a large swing range of the consumables, which can easily cause the consumables to break, making it difficult for the extrusion mechanism to continuously supply the consumables, and thus causing the printing nozzle to be misaligned, which cannot ensure the stable operation of the printing work and reduces the printing efficiency.

Detailed Implementation
[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1 to 4 As shown, a 3D printing device with anti-misalignment and material breakage detection includes a device frame 10, the device frame 10 includes a bottom support 101, the top of the bottom support 101 is fixedly connected to the bottom of the printing table 11, and the two sides of the bottom support 101 are slidably connected to drive supports 102, and the printing components 12 are slidably connected to the drive supports 102.
[0026] The guide mechanism 20 includes a guide ring 21, which is slidably connected to the top of the drive bracket 102. A transmission rod 22 is slidably connected to one side of the guide ring 21. The bottom of the transmission rod 22 is fixedly connected to the printing assembly 12. The other side of the guide ring 21 is fixedly connected to one end of the guide rod 23. The other end of the guide rod 23 is slidably connected to the feeding assembly 30.
[0027] The feeding assembly 30 includes a connecting plate 31, which is fixedly connected to the end of the equipment frame 10 away from the printing table 11. Support plates 32 are fixed on both sides of the connecting plate 31, and a connecting rod 33 is assembled between the support plates 32. A rotating cylinder 34 is slidably connected to the outside of the connecting rod 33, and a feeding disc 35 is rotatably connected to the outside of the rotating cylinder 34. One side of the rotating cylinder 34 is fixedly connected to a transmission block 36, and the transmission block 36 is slidably connected to the other end of the guide rod 23.
[0028] In this embodiment, it should be noted that the drive bracket 102 can effectively move axially towards the drive element, which is a conventional technical means and will not be elaborated on here. The axial drive drives the printing component 12 to move within the space inside the equipment frame 10, so that the printing component 12 outputs to the printing table 11. When the printing component 12 moves axially, the transmission rod 22 synchronously drives the transmission block 36 in the feeding component 30 to move. The transmission block 36 synchronously drives the rotating cylinder 34 and the feeding tray 35 to slide on the connecting rod 33, ensuring that when the print head moves, it will not generate a large pulling force with the printing consumables, thus preventing the print head from moving. At the same time, it can reduce the swing of the printing consumables and reduce the risk of consumable breakage. After the printing component 12 drives the consumables to perform the hot melting operation, it will apply power to the feeding tray 35 through the guide ring 21 to ensure that the feeding tray 35 continuously feeds the printing component 12.
[0029] like Figure 2 As shown, the printing assembly 12 includes lifters that are slidably connected to both sides of the drive bracket 102. A drive rod 121 is fixed between the two lifters, and a driver 122 is slidably connected to the drive rod 121. It should be noted that the lifters are vertical drive elements, and the driver 122 is a left-right drive element. By cooperating with the drive bracket 102, they can achieve omnidirectional movement.
[0030] Preferably, one side of the driver 122 is fixedly connected to the transmission rod 22, and the other end of the driver 122 is fixedly connected to the print head 123. The driver 122 can synchronously drive the guide ring 21 and the print head 123 to move synchronously through the transmission rod 22, ensuring that the guide ring 21 drives the printing consumables to reduce friction between them and the print head 123.
[0031] Preferably, the top of the print head 123 has a feed port, which can effectively connect with the printing consumables, ensuring continuous output of the printing consumables and reducing the risk of printing misalignment.
[0032] like Figure 4 As shown, printing consumables are wound around the outside of the feed tray 35, and the output end of the printing consumables passes through the guide ring 21 and is connected to the feed port. It should be noted that the connecting rod 33 is detachably connected to the support plate 32, which can effectively replace the feed tray 35.
[0033] Preferably, the other end of the guide ring 21 is provided with a rotating groove, the guide rod 23 is rotatably connected to the inside of the rotating groove, and the end of the guide rod 23 that is rotatably connected to the rotating groove is annular.
[0034] In this embodiment, based on the previous embodiment, when the drive bracket 102 is driven to adjust, it drives the guide ring 21 to move axially. At this time, the guide rod 23 rotates with the rotating groove in the guide ring 21, and at the same time, the other end of the guide rod 23 is slidably connected with the transmission block 36. Simultaneously, the rotating cylinder 34 and the connecting rod 33 are driven to rotate. When the driver 122 is working, the guide rod 23 synchronously drives the rotating cylinder 34 and the feeding plate 35 to move and adjust on the connecting rod 33.
[0035] Preferably, a detection plate is fixed to the top of the drive bracket 102, and the detection plate is located above the guide ring 21. It should be noted that an infrared sensor is fixed to the bottom of the detection plate, which can monitor the status of the consumables in the guide ring 21 in real time. When the consumables break, the sensor will not be able to receive the infrared signal that should be reflected, and an alarm will be triggered to remind the user.
[0036] The working principle of this utility model is as follows: During printing, the print head 123 is driven by the drive bracket 102 and the driver 122 to form a spherical shape above the print table 11. When the driver 122 moves the print head 123, it simultaneously drives the guide ring 21 to slide on the top of the drive bracket 102 via the transmission rod 22. This ensures that the internal printing consumables are aligned with the print head 123, preventing misalignment caused by consumable breakage. When the guide ring 21 slides, it... The guide rod 23 synchronously drives the transmission block 36, which in turn drives the feeding tray 35 to move synchronously through the transmission cylinder. This ensures that the feeding tray 35 drives the printing consumables and the guide ring 21 to move synchronously, preventing the consumables from swinging during the movement of the guide ring 21 and causing them to break. At the same time, it can reduce the friction between the printing consumables and the guide ring 21, ensuring the stability of the consumables during transmission. During the transmission of the printing consumables, the detection plate located above the drive bracket 102 can monitor the printing consumables to prevent them from breaking during transmission.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
