[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] A 3D printing device for municipal drainage pipes includes a frame 1, with longitudinal linear motors 9 symmetrically arranged inside the frame 1 (which is prior art and its working principle will not be described here), a bracket 10 on the longitudinal linear motors 9, and transverse linear motors 8 (which is prior art and its working principle will not be described here) between the brackets 10, a mounting plate 6 on the transverse linear motors 8, a nozzle 2 on the bottom surface of the mounting plate 6, and a worktable 11 on the bottom surface inside the frame 1.

[0022] The nozzle 2 is equipped with a cooling mechanism on its outer wall. The use of the cooling mechanism facilitates the cooling of the nozzle 2, preventing damage to the nozzle 2 due to high temperature, thereby improving the service life of the nozzle 2.

[0023] In this invention, the cooling mechanism includes a spiral cooling pipe 7 sleeved on the outer wall of the nozzle 2, a water tank 3 disposed on the top surface of the frame 1, and a miniature water pump 12 disposed inside the water tank 3, used to transport cold water from the water tank 3 to the spiral cooling pipe 7; the outlet end of the miniature water pump 12 is provided with an inlet corrugated pipe 5, one end of which is connected to the inlet end of the spiral cooling pipe 7; the outlet end of the spiral cooling pipe 7 is provided with a return corrugated pipe 4, one end of which is connected to the water tank 3; and a cooler 2 is installed inside the water tank 3. 1. The cold end of the cooler 21 is located inside the water tank 3, and the hot end is located outside the water tank 3. It is used to cool the water in the water tank 3, which is beneficial to the cooling of the nozzle 2. The water inlet of the micro water pump 12 is provided with a water guide pipe 13. One end of the water guide pipe 13 is provided with a stirring element. By using the stirring element, the water in the water tank 3 can be stirred, which makes it easier to mix the hot water that just enters the water tank 3 with the cold water in the water tank 3, ensuring that the water that re-enters the spiral cooling pipe 7 is cold water, thereby improving the cooling efficiency of the nozzle 2.

[0024] In this utility model, the stirring component includes a circular cylinder 14 disposed at one end of the water guide pipe 13, a connecting shaft 16 rotatably disposed inside the circular cylinder 14, and a sleeve 18 disposed at the outer end of the connecting shaft 16. A plurality of stirring blades 17 are evenly disposed on the outer wall of the sleeve 18. An annular block 19 is disposed on the outer wall of the connecting shaft 16 inside the circular cylinder 14. A plurality of rectangular plates 20 are evenly disposed on the outer wall of the annular block 19. A water inlet pipe 15 is disposed on the outer wall of the circular cylinder 14.

[0025] In this utility model, the rectangular plate 20 is in contact with the inner wall of the cylindrical tube 14, and the water inlet pipe 15 and the water guide pipe 13 are staggered, which facilitates the rotation of the stirring blade 17, thereby facilitating the stirring of the water in the water tank 3.

[0026] Working principle: When in use, the horizontal linear motor 8 and the vertical linear motor 9 of this utility model can move the nozzle 2 within the frame 1, thereby facilitating the printing of water pipes;

[0027] When cooling the nozzle 2, the micro water pump 12 is turned on first. The water in the water tank 3 enters the cylindrical cylinder 14 through the water inlet pipe 15. Then, under the action of the rectangular plate 20, the annular block 19 and the connecting shaft 16 rotate, thereby driving the stirring blade 17 to rotate, so as to stir the water in the water tank 3. This makes it easier to mix the hot water that just entered the water tank 3 with the cold water in the water tank 3, ensuring that the water that re-enters the spiral cooling pipe 7 is cold water, thereby improving the cooling efficiency of the nozzle 2.

[0028] Then, water enters the micro water pump 12 through the water guide pipe 13, and then enters the spiral cooling pipe 7 through the water inlet corrugated pipe 5. Finally, the water flows back to the water tank 3 through the water return corrugated pipe 4, realizing the circulation of water, which facilitates the cooling of the nozzle 2.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
