Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a conveyor belt type 3D printer. Background Art

[0002] Conveyor belt 3D printing technology is an innovative design developed based on traditional 3D printing technology. Its core feature is the use of a dynamic, continuously moving print bed, namely a conveyor belt, instead of a conventional fixed printing platform.

[0003] However, there are still some problems with the existing conveyor belt 3D printing technology. During high-speed printing, many early conveyor belt 3D printers may affect the stability of the printing plane due to the softness of the conveyor belt, thereby reducing the printing accuracy. In addition, due to the influence of hardware and software, the printing speed is relatively slow, resulting in low production efficiency. In addition, the lack of an intelligent auxiliary system for leveling will cause errors when the user manually levels, often resulting in printing failures or reduced product quality due to uneven bed surfaces.

[0004] Therefore, it is necessary to provide a conveyor belt type 3D printer to solve the above technical problems. Utility Model Content

[0013] Beneficial effects:

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] The following is a detailed description of a new type of conveyor belt 3D printer in conjunction with a specific embodiment.

[0029] refer to Figures 1 to 4 The utility model provides a conveyor belt type 3D printer, comprising: a conveyor belt 1 made of metal material, the inner surface of the conveyor belt 1 is wound around the driving end of the transmission device 2, a magnetic hot bed platform 8 is arranged on the inner side of the conveyor belt 1, and the two ends of the transmission device 2 are connected with a tensioning device 3 that can adjust the loose end of the transmission belt, a mounting frame 4 is arranged above the conveyor belt 1, and the mounting frame 4 is connected to the tensioning device 3 through a support rod 5, and a "П"-shaped longitudinal guide rail 9 is installed on the inner side of the mounting frame 4, and the two ends of the longitudinal guide rail 9 are respectively slidably connected to a first moving block 11 and a second moving block 12, and the first moving block 11 and the second moving block 12 are installed at the two ends of a transverse guide rail 10, and the transverse guide rail 10 is slidably connected to a printing device 6, and an induction sheet 15 is installed on the end surface of the printing device 6, and the induction sheet 15 is connected to a strain gauge, and the strain gauge is electrically connected to a control board 16, and the control board 16 is installed at the upper end of the printing device 6.

[0030] It should be noted that the printing device 6 uses an existing 3D printing extruder and uses a conveyor belt 1 made of metal material to replace the soft conveyor belt 1. Compared with the soft conveyor belt 1, it is more resistant to deformation, which helps to prevent the model from being deformed by external forces during the printing process. The magnetic hot bed platform 8 can provide sufficient magnetic adsorption force to adsorb the metal conveyor belt 1 on the hot bed, preventing the model from shaking when the print head prints quickly, thereby increasing the printing speed.

[0031] When the nozzle of the printing device 6 contacts the hot bed, the deformation is transmitted to the strain gauge through the sensing sheet 15. The tiny deformation of the strain gauge can output a piezoelectric signal. The signal is transmitted to the chip in the control board 16 for processing, and the algorithm of the program is used to identify whether the nozzle contacts the hot bed, thereby ensuring real-time and high-precision measurement of the distance between the print head and the hot bed, thereby improving the printing quality.

[0032] In the embodiment of the present utility model, the magnetic hot bed platform 8 is installed with a plurality of detection sensors, and the detection sensors are electrically connected to the control board 16 .

[0033] It should be noted that: by setting up multiple detection sensors on the magnetic hot bed platform 8, the system can form a leveling reference line according to the pressure feedback of the nozzle of the printing device 6 at each point, and then use the algorithm to analyze and process the data, automatically generate and execute the leveling instruction, and adjust it through the tensioning device 3 to achieve dynamic and continuous automatic leveling during printing, thereby improving the printing quality.

[0034] In the embodiments of the present invention, reference is made to Figure 1 As shown, a high temperature resistant Teflon cloth is provided between the magnetic hot bed platform 8 and the conveyor belt 1 .

[0035] It should be noted that the Teflon cloth is both resistant to high temperatures and has a lubricating effect, and can effectively reduce the resistance of the conveyor belt 1 when it is transmitted on the magnetic hot bed platform 8;

[0036] In the embodiments of the present invention, reference is made to Figure 2 , Figure 3 As shown, a limiting shaft 13 is installed between the first moving block 11 and the second moving block 12 , and the limiting shaft 13 is slidably connected to a limiting hole 14 , and the limiting hole 14 is arranged on the side of the printing device 6 .

[0037] In the embodiments of the present invention, reference is made to Figure 3 As shown, the number of the limiting shafts 13 is two, and the limiting holes 14 are respectively arranged at the upper end and the lower end of the end surface of the printing device 6 .

[0038] It should be noted that by providing the limiting shaft 13 and sliding on the limiting shaft 13 through the limiting hole 14, the stability of the printing device 6 when moving left and right can be improved.

[0039] In the embodiments of the present invention, reference is made to Figure 1 As shown, a touch-operable display screen 7 is installed on the upper end of the tensioning device 3, and a cabinet is installed on the inner side of the magnetic hot bed platform 8.

[0040] It should be noted that: by installing the chassis on the inner side of the magnetic hot bed platform 8, while ensuring efficient printing, the size of the equipment is exquisitely optimized, which not only saves the use space, but also makes the overall structure more compact and integrated, adapting to more diversified application scenarios, including small studio spaces or industrial production line environments that require high integration. By setting up the display screen 7, the user can set and operate various parameters through a simple and intuitive graphical interface, which significantly simplifies the equipment control process and improves user-friendliness, so that non-professional users can also quickly get started and enjoy a smooth use experience.

[0041] The working principle of a conveyor belt 1-type 3D printer provided by the utility model is as follows:

[0042] By using a conveyor belt 1 made of metal material to replace the soft conveyor belt 1, it is more resistant to deformation than the soft conveyor belt 1, which helps to prevent the model from being deformed by external forces during the printing process, and the magnetic hot bed platform 8 can provide sufficient magnetic adsorption force to adsorb the metal conveyor belt 1 on the hot bed, prevent the model from shaking when the print head prints quickly, and improve the printing speed. When the nozzle of the printing device 6 contacts the hot bed, the deformation is transmitted to the strain gauge through the induction sheet 15. The tiny deformation of the strain gauge can output a piezoelectric signal. The signal is transmitted to the chip in the control board 16 for processing, and the algorithm of the program is used to identify whether the nozzle contacts the hot bed, ensuring real-time and high-precision measurement of the distance between the print head and the hot bed, and improving the printing quality.

[0043] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0044] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
