Description

Technical Field

[0001] The utility model belongs to the technical field of nozzles, and in particular relates to a heat dissipation type 3D printing nozzle. Background Art

[0002] During the 3D printing process, the nozzle needs to reach a specific melting temperature to extrude the material smoothly. If the nozzle cannot dissipate heat effectively, its temperature may be too high, which will not only affect the print quality, but may also cause the material to burn or clog the nozzle. Through heat dissipation design, it can ensure that the nozzle remains within the appropriate temperature range, thereby ensuring smooth printing.

[0003] Continuous heating can cause thermal fatigue of the nozzle material, and long-term high temperature working environment may shorten the service life of the nozzle. The heat dissipation system can help reduce the temperature of the nozzle, slow down thermal damage, and thus extend the service life of the nozzle.

[0004] Therefore, in order to ensure the smooth progress of the 3D printing process, improve printing quality and accuracy, extend the service life of the nozzle and increase the printing speed, effective heat dissipation design of the 3D printing nozzle is required.

[0005] In summary, the present application provides a heat dissipation type 3D printing nozzle, the nozzle structure combines the centralized installation of multiple pipelines, and at the same time limits the heat dissipation space of the pipelines. After the heat is concentrated in the centralized space, the heat dissipation treatment is completed uniformly through the heat dissipation fan. At the same time, the upper and lower racks are used to place the air collection direction of the fan and the nozzle on the same vertical line, which improves the heat dissipation efficiency. At the same time, the inclined feed pipeline structure is used to save the installation space. Summary of the invention

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a heat dissipation type 3D printing nozzle includes a nozzle, a heat dissipation fan and a feed plug: the top end face of the nozzle 8 is an arched structure, and the nozzle 8 is evenly provided with three groups of feed ports 10 along the top end face, and the feed ports 10 are obliquely inserted with three groups of feed plugs 7; the outer ring of the nozzle 8 is clamped with a support frame 6 through a carrier plate 1, and a limit plate 3 is installed on the top of the support frame 6 through a longitudinal connecting rod 9, and a heat dissipation fan 2 is fixedly installed on the top of the limit plate 3 through a pad 4; the pad 4 and the limit plate 3 are provided with through holes along the heat dissipation vent. Among them, the nozzle structure combines the centralized installation of multiple pipelines, and at the same time limits the heat dissipation space of the pipelines. After the concentrated space is used to complete the heat concentration, the heat dissipation treatment is completed uniformly through the heat dissipation fan. At the same time, the upper and lower racks are installed to place the air collection direction of the fan on the same vertical line as the nozzle, thereby improving the heat dissipation efficiency. At the same time, the oblique feed pipeline structure is also used to achieve the effect of saving installation space.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the limit plate 3 is integrally connected with a special-shaped carrier 5, the special-shaped carrier 5 is an inverted "claw" structure, the special-shaped carrier 5 is an arc-shaped smooth end surface structure from bottom to top, and the special-shaped carrier 5 is in limited contact with the feed plug 7. The inverted special-shaped carrier 5 at the bottom of the limit plate 3 can further limit the installation position of the feed plug 7, and play a guiding and protective role.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the feeding insert 7 is provided with a heat sink. The heat sink can transfer heat more effectively, so that the heat dissipation fan 2 can complete the heat dissipation process more conveniently.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the limit plate 3 is provided with a groove 11 along the installation position of the three groups of feed plugs 7. The support frame 6 retains an arc-shaped bending structure along the installation position of the three groups of feed plugs 7. Among them, the position of the groove 11 is the installation position of the feed plug 7, which can further reduce the installation space and improve the structural strength of the installation.

[0026] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
