A lead screw 15 is fixedly mounted on the output end of each servo motor 16, and the outer surface of each lead screw 15 is rotatably connected to the inner wall of one end of the guide plate 12. Two handles 3 are arranged on the outside of the printing box 1, and the sides of the two handles 3 that are close to each other are fixedly connected to the sides of the two box doors 4 that are away from each other. The handles 3 facilitate opening the box doors 4 to avoid inconvenience caused by the smooth surface material of the box doors 4.

[0033] Reference Figure 1-3 The outer surface of each lead screw 15 is threadedly connected to two sliders 14. Four bases 2 are arranged on the bottom of the printing box 1, and the four bases 2 are distributed in a rectangular array at the four corners of the bottom of the printing box 1. By setting the base 2, the printing box 1 is supported, and at the same time, the base 2 can be disassembled.

[0034] Reference Figure 2 and Figure 3The upper surface of each slider 14 is fixedly mounted with an electric push rod 13, and two supporting angle plates 11 are arranged inside the printing box 1, and the bottom surface of each supporting angle plate 11 is fixedly connected to the top of the electric push rod 13. In addition, two sets of fixing bolts 19 are threadedly connected to the inner wall of each base 2, and the outer surface of each set of fixing bolts 19 is threadedly connected to the inner wall of the printing box 1. The fixing bolts 19 play the role of installing the limiting base 2, and the use of the fixing bolts 19 allows the base 2 to be flexibly disassembled and assembled.

[0035] Reference Figure 3 and Figure 4 A small motor 10 is fixedly mounted on the outer surface of each supporting angle plate 11, and the output end of each small motor 10 is rotatably connected to the inner wall of the supporting angle plate 11. Two first linear slides 5 are fixedly mounted on the inner top wall and the inner bottom wall of the printing box 1, and a second linear slide 7 is fixedly mounted on the side of the two first linear slides 5 close to each other. The first linear slide 5 and the second linear slide 7 are used for the up-down and left-right movement during printing, and both are GKF80 models.

[0038] Working principle: First, the small motor 10, the servo motor 16, the second linear slide 7, the first linear slide 5 and the electric push rod 13 are powered on. When printing is required, the corresponding printing material is provided to the printer head 6. The printer head 6 cooperates with the first linear slide 5 and the second linear slide 7 to print the denture on the printing plate 9. Since the color of the printed denture is determined by the printing material, when the color of the printing material does not meet the color required by the denture, the servo motor 16 is started, and the servo motor 16 drives the lead screw 15 to rotate, and the lead screw 15 drives the slider 14 to move, and then the slider 14 drives the printing plate 9 moves, and when the printing plate 9 is moved to just above the immersion container 8, the servo motor 16 is stopped, and the small motor 10 is started. The small motor 10 drives the printing plate 9 to rotate, so as to flip the printed denture. Since the printing material will stick to the printing plate 9, the denture will not fall off. The small motor 10 is stopped, and the electric push rod 13 is started. The electric push rod 13 contracts, driving the supporting angle plate 11 and the printing plate 9 to descend, and then the printed denture is immersed in the immersion container 8. The electric push rod 13 is stopped. Generally, the immersion time is thirty minutes. After thirty minutes, the printed denture is taken out according to the above reverse steps.
