[0028] The working principle of the device for printing a talking valve of multiple materials provided by the utility model is as follows:

[0029] When the printing work of the talking valve is performed, the printer 1 is started, the cantilever 2 is opened and the conversion bin 3 is operated along the predetermined track, after the corresponding remote control valve 19 is started, the material is injected into the nozzle 8 located in the middle through the material injection pipe one 15, the hose 16 and the material injection pipe two 18, so that the 3D printing work is completed.

[0030] During the printing process, when changing to different materials, the operator first connects the three material injection tubes 15 to the guide tubes of different materials. Then, the remote control valve 19 on the material injection tube 18, which is currently guiding material, closes to stop the injection. Next, the electric telescopic rod 221 is activated. The output shaft of the electric telescopic rod 221 retracts, causing the pin 223 to move out of the corresponding retaining groove 21, thus releasing the limiting effect of the clamping disc 20. Immediately afterward, the regulating motor 14 is activated. The rotation of the regulating motor 14's output shaft drives the threaded rod 13 to rotate, thereby moving the transverse block 10. During the movement of the transverse block 10, the toothed plate 12 moves, which in turn drives the drive gear 9 and the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the swing chamber 5 to rotate, thereby changing the positions of the three sliding boxes 6 and the three nozzles 8. The nozzle 8 corresponding to the material to be used is adjusted to the position on the central axis (central axis position: e.g., ...). Figure 5 (As shown in the initial state, the nozzle 8 is located in the middle). Then, the motor 14 is turned off, and the electric telescopic rod 221 is started again. At this time, through the rotation of the threaded rod 13, the corresponding retaining groove 21 is aligned with the pin 223, so that the pin 223 is inserted to position the threaded rod 13 and the nozzle 8. Finally, the corresponding remote control valve 19 is opened, and the material continues to be ejected through the adjusted nozzle 8 for printing.

[0031] It should be noted that the clamping disc 20, the holding groove 21, the side plate 22, the electric telescopic rod 221, the moving plate 222 and the pin 223 described in this utility model are auxiliary fixing schemes for switching positions of the nozzle 8. Although this scheme can improve switching stability, it is not the core invention point of this utility model.

[0032] The core innovation of this utility model lies in: using a rotating shaft

[0033] 4. The drive swing chamber 5 rotates three sliding boxes 6, enabling dynamic switching of multiple nozzles 8. This invention completely solves the problems of material mixing and printing interruption without the clamping disc 20, holding groove 21, side plate 22, electric telescopic rod 221, moving plate 222, and pin 223. That is, it seamlessly switches nozzles 8 for different materials during the printing process through mechanical rotation.

[0034] Compared with related technologies, the multi-material printing device for speaking valves provided by this utility model has the following beneficial effects:

[0035] The utility model provides a kind of device of multi-material printing talking valve, by default three injection tube one 15 and the connecting of external material guide pipe, in the process of printer 1 operation, different materials corresponding nozzle 8 can be switched according to the product demand of printing quickly, the whole process reduces the participation of artificial, to improve the accuracy of printing to some extent, while the nozzle 8 used by each kind of material is different, prevent the mutual intermingling between materials, improve the quality of product printing to some extent.
