The surface of the rotating disk 4 has multiple threaded through holes 13 evenly distributed in a circle. A storage cylinder 2 is provided inside the threaded through holes 13. An external threaded sleeve 19 is fixedly fitted on the surface of the storage cylinder 2. The external threaded sleeve 19 is threadedly connected to the inside of the threaded through holes 13. A retaining ring 3 is fixedly connected to the top surface of the external threaded sleeve 19. A gear ring 5 is fixedly fitted on the side of the rotating disk 4. A base plate 9 is provided at the bottom end of the mounting column 1. A positioning component is provided in the middle of the base plate 9. A rotating component is provided on one side of the base plate 9. Two limiting grooves 14 are provided on the bottom surface of the mounting column 1.

A nozzle 10 is fixedly fitted on the surface of the base plate 9.

[0029] Specifically, during use, rotating the assembly causes the gear ring 5 to rotate, which in turn drives the rotating disk 4 to rotate. The rotating disk 4 then drives the material storage cylinder 2 to rotate, allowing for the replacement of the material storage cylinder 2 at the top of the printhead 10, thus enabling the use of different printing materials. The material storage cylinder 2 can be disassembled and replaced using the engagement of the external threaded sleeve 19 and the threaded through hole 13. The base plate 9 can be disassembled using the engagement of the positioning assembly and the threaded hole 15. The base plate 9 is initially positioned at the bottom of the mounting post 1 by the limiting groove 14 and the limiting insert 16. Finally, the positioning assembly secures the base plate 9 to the mounting post 1, completing the installation.

[0030] In this embodiment, a mounting plate is fixedly connected to the top surface of the mounting column 1, and the surface of the mounting plate has a plurality of mounting holes evenly distributed in a circle.

[0031] Specifically, the mounting pin 1 can be fixedly installed at a suitable location on the food 3D printer through the mounting holes on the surface of the mounting plate.

[0032] In this embodiment, the positioning component includes a mounting through hole 17 opened in the middle of the base plate 9. A threaded sleeve 11 is fixedly connected to the inner wall of the mounting through hole 17. A threaded rod 18 is threadedly connected to the inside of the threaded sleeve 11. A rotating cap 12 is fixedly connected to the bottom end of the threaded rod 18. The threaded rod 18 is threadedly connected to the inside of the threaded hole 15.

[0033] Specifically, by rotating the rotating cap 12, the threaded rod 18 can be rotated, and the threaded rod 18 can be screwed into or out of the threaded hole 15 under the action of the threaded sleeve 11, thus realizing the installation and disassembly of the base plate 9.

[0034] In this embodiment, the rotating assembly includes a support plate 8 fixedly connected to the side of the base plate 9, a servo motor 7 fixedly connected to the top surface of the support plate 8, a rotating gear 6 fixedly connected to the output shaft of the servo motor 7, and the rotating gear 6 meshing with the gear ring 5.

[0035] Specifically, the servo motor 7 can drive the rotary gear 6 to rotate, and the rotation of the rotary gear 6 can drive the gear ring 5 to rotate the rotary disk 4.

[0036] The specific working principle and usage method of this utility model are as follows:

[0037] This invention provides a multi-channel 3D printing nozzle, such as... Figure 1-5 As shown, during use, align the top mounting plate of mounting column 1 with the installation position of the food 3D printer, and securely fix mounting column 1 with bolts through the mounting holes. Next, install base plate 9, align the limiting insert 16 on base plate 9 with the limiting groove 14 on the bottom surface of mounting column 1 and insert it to achieve initial positioning; hold rotating cap 12 and rotate it clockwise to drive threaded rod 18 to rotate along threaded sleeve 11, so that threaded rod 18 is screwed into threaded hole 15 of mounting column 1 and tightened, completing the fixation of base plate 9 and mounting column 1.

[0038] Then, load different types of printing materials into each storage cylinder 2. Hold the storage cylinder 2 and align the external threaded sleeve 19 with the threaded through hole 13 of the rotating disk 4. Rotate the storage cylinder 2 clockwise to make the external threaded sleeve 19 threadedly connected to the threaded through hole 13 until the retaining ring 3 fits against the top surface of the rotating disk 4, thus completing the installation of the storage cylinder 2. Install all the storage cylinders 2 in this way.

[0039] During printing, select the corresponding material storage cylinder 2 according to the printing requirements, start the servo motor 7 through the controller, drive the rotating gear 6 to rotate, the rotating gear 6 drives the meshing gear ring 5 to rotate, and then make the rotating disk 4 rotate around the mounting column 1, so that the target material storage cylinder 2 is directly above the printhead 10, and then turn off the servo motor 7 to start printing.

[0040] When it is necessary to replace the material in the storage cylinder 2 or clean the storage cylinder 2, rotate the storage cylinder 2 counterclockwise to disengage the external threaded sleeve 19 from the threaded through hole 13, and then remove the storage cylinder 2; if it is necessary to disassemble the base plate 9 to inspect the nozzle 10, rotate the rotating cap 12 counterclockwise to disengage the threaded rod 18 from the threaded hole 15, and pull the base plate 9 to disengage the limiting insert 16 from the limiting groove 14.
