The box body 1 can fix and limit the rotating motor 9, which is convenient for the stable use of the rotating motor 9. When the rotating motor 9 is opened, the output shaft of the rotating motor 9 can drive the screw 10 to rotate. When the screw 10 rotates, it can drive the rotating rod 11 to rotate along the box body 1. The box body 1 can limit the screw 10 through the rotating rod 11, which is conducive to the stable rotation of the screw 10. When the screw 10 rotates, the bearing plate 12 threadedly connected to the screw 10 will move upward. When the bearing plate 12 moves upward, it will move upward along the limiting rod 13. The box body 1 and the fixed block 14 can limit the bearing plate 12 through the limiting rod 13, which is convenient for the stable movement of the bearing plate 12.

[0043] After the carrier plate 12 is moved to correspond to the bottom of the 3D printing nozzle 35, the 3D printing nozzle 35 is turned on through the control panel 8. When the 3D printing nozzle 35 is turned on, the 3D printing nozzle 35 can spray the raw material to the corresponding position on the carrier plate 12 to print and form the three-dimensional model raw material. When the position of the 3D printing nozzle 35 needs to be adjusted according to the three-dimensional model, the control panel 8 turns on the first electric slider 18. When the first electric slider 18 is turned on, the first electric slider 18 moves horizontally along the first guide rail 16. When the first electric slider 18 moves, it can pass through the connecting block 15, the second guide rail 17, the second electric slider 19, the hydraulic cylinder 24, the fixed frame 20, the movable plate 25, and the block 2 6.

Because the first guide rail 16 and the second guide rail 17 are in a vertical state, the 3D printing nozzle 35 can be moved in multiple directions.

[0044] During the process of printing the three-dimensional model through the 3D printing nozzle 35, the control panel 8 turns on the rotating motor 9 according to the progress of the three-dimensional model printing, and the rotating motor 9 drives the screw 10 to rotate, so that the carrier plate 12 threadedly connected to the screw 10 gradually moves downward according to the progress of the three-dimensional model printing. During the printing of the three-dimensional model, the heat generated by the 3D printing nozzle 35 is likely to affect the inner side of the fixed frame 20, and the induced draft fan 23 inside the induced draft tube 22 is turned on. When the induced draft fan 23 is turned on, the induced draft fan 23 can pass The air duct 22 and the ventilation holes 21 on the fixed frame 20 extract the air in the fixed frame 20 to promote the flow of air in the fixed frame 20, which helps to dissipate heat in the fixed frame 20. During the printing of the three-dimensional model, the first transparent baffle 6 in the first retaining hole 4 on the box body 1 and the second transparent baffle 7 in the second retaining hole 5 on the box door 3 help to observe the three-dimensional model printed on the upper side of the carrier plate 12. After the three-dimensional model is printed, the box door 3 is opened to facilitate the removal of the three-dimensional model after printing on the upper side of the carrier plate 12.

[0045] When it is necessary to clean the residual raw materials in the 3D printing nozzle 35, the hydraulic cylinder 24 on the lower surface of the second electric slider 19 is opened. When the hydraulic cylinder 24 is opened, the output rod of the hydraulic cylinder 24 can drive the movable plate 25 to move downward. When the movable plate 25 moves downward, it can drive the limit block 29 to move downward along the inner side of the fixed frame 20 through the card block 26, the limit pad 27 and the card slot 28. When the limit block 29 moves downward, it can drive the connecting plate 34 to move downward through the second limit groove 33, the limit ring 31, the first limit groove 32 and the positioning block 30. The connecting plate 34 moves downward. When moving, it can drive the 3D printing nozzle 35 to move downward. After the limit block 29 is moved to the outside of the fixed frame 20, the fixed frame 20 will cancel the blocking limit of the limit block 29, and further move the limit block 29 along the block 26 and the limit pad 27 through the card slot 28 in the direction away from each other to separate the limit blocks 29, so that the second limit groove 33 and the first limit groove 32 on the limit block 29 cancel the limit on the limit ring 31 and the positioning block 30, so as to facilitate the disassembly and removal of the 3D printing nozzle 35, which is beneficial to the cleaning of the residual raw materials in the 3D printing nozzle 35.

[0046] After cleaning the residual raw materials in the 3D printing nozzle 35, the limit ring 31 and the positioning block 30 are respectively reset to the second limit groove 33 and the first limit groove 32 on the limit block 29, and the limit plate 25 is moved and reset along the block 26 and the limit pad 27 through the slot 28 on the limit block 29, and the hydraulic cylinder 24 is opened, so that the movable plate 25 moves upward along the inner side of the fixed frame 20. When the movable plate 25 moves upward, the limit block 29 can be driven by the block 26, the limit pad 27 and the slot 28 to move upward along the inner side of the fixed frame 20. The fixed frame 20 can limit the limit blocks 29, and the limit block 29 can limit the connecting plate 34 and the 3D printing nozzle 35 through the second limit groove 33, the limit ring 31, the first limit groove 32 and the positioning block 30, so as to facilitate the use of the 3D printing nozzle 35.

[0047] During use, it is helpful to disassemble the 3D printing nozzle 35. After using the 3D printing device for a long time, when it is necessary to clean the residual material in the 3D printing nozzle 35, the 3D printing nozzle 35 can be easily disassembled to facilitate cleaning of the residual material in the 3D printing nozzle 35, which helps the 3D printing device to print the three-dimensional model evenly.
