[0002] When patients need to replace their teeth, dentures are often used to replace problematic teeth. However, the color of the new denture is different from that of other teeth in the patient's mouth. After replacement, the color of the denture will be inconsistent with that of other teeth in the patient's mouth. Therefore, it is necessary to change the color of the denture in advance according to the color of other teeth in the patient's mouth. Currently, dyeing equipment is often used to dye the denture.

The dyeing tank 10 has an opening and a piston 11 is provided inside. A pressure regulating device is provided below the piston 11. When the cover plate 5 covers the opening on the dyeing tank 10 and forms a sealed state, the pressure regulating device controls the piston 11 and the dyeing tank 10 to move relative to each other, so that the air pressure in the internal space of the dyeing tank 10 above the piston 11 changes. A color fixing device 12 is provided on the other side of the elevator 3 for irradiating and fixing the denture after dyeing. A loading conveyor 13 and a discharging conveyor 14 are provided on the front and rear sides of the workbench 1, respectively, for conveying the dyeing dish 6 containing the denture. A visual detection unit 15 is also provided above the discharging conveyor 14 for detecting the color of the surface of the denture after dyeing. The dyeing dish 6 is open at the top, and a symmetrical water outlet 601 is provided in the middle of its side wall, and uniformly distributed through holes 602 are provided on the bottom wall of the dyeing dish 6. The bottom of the dyeing dish 6 is open, and a through cylindrical structure is formed corresponding to its upper opening. The bottom wall of the dyeing dish 6 is a porous disc 603, and its side wall is slidably connected to the inner wall of the dyeing dish 6, and the top wall is in conflict with the end of the rotating shaft 7. The color fixing device 12 includes a color fixing tank 1201, and a boss 1202 is fixedly connected to the center of the bottom wall of the color fixing tank 1201, and an irradiation unit is provided on the side wall. When the dyeing dish 6 is sleeved on the boss 1202, the boss 1202 lifts the porous disc 603, so that the denture placed on its upper surface is located above the upper opening of the dyeing dish 6, so that the irradiation unit irradiates and fixes the denture. The pressure regulating device comprises a cylinder 16 , an outer tube of the cylinder 16 is fixedly connected to the inside of the workbench 1 , and an output end of the cylinder 16 is fixedly connected to the bottom wall of the piston 11 .

[0018] It should be noted that the turntable 2 can be a pneumatic turntable or an electric turntable, which only needs to be able to accurately drive the lift 3 to rotate in a circle at an angle of 45°.

[0019] The color fixing device 12 is mainly used to irradiate the dyed denture through the irradiation unit inside it, so as to firmly attach the dyeing factor to the denture.

[0020] The operation process of an automatic impregnation device for dentures is as follows: First, the impregnation dish 6 with the denture on the feeding conveyor 13 is magnetically clamped by the cover plate 5, and then the turntable 2 drives the elevator 3 to rotate to the top of the impregnation tank 10. The elevator 3 drives the cover plate 5 to cover the impregnation tank 10 through the bracket 4, so that a closed space is formed in the impregnation tank 10, and then the piston 11 is pushed upward by the cylinder 16. While driving the impregnation liquid to submerge the denture, the closed space of the impregnation tank 10 between the piston 11 and the cover plate 5 is compressed to increase the internal air pressure. At the same time, the motor 9 drives the impeller 8 to rotate through the rotating shaft 7. Under the action of the centrifugal force of the rotation of the impeller 8, the impregnation liquid in the impregnation dish 6 is discharged from the water outlet 601, and the impregnation liquid at the bottom of the impregnation tank 10 enters the interior of the impregnation dish 6 and the denture through the through hole 602 under the action of the suction force generated. The porous disc 603 is in contact with each other, so that the dyeing liquid in the dyeing dish 6 is continuously renewed. Due to the resistance of the rotating shaft 7 to the porous disc 603, the porous disc 603 will not rise under the impact of the water flow and the buoyancy at this time; when the dyeing is completed, the dyeing dish 6 containing the denture is moved into the fixing tank 1201 through the cooperation of the elevator 3 and the turntable, and the dyeing dish 6 is sleeved on the boss 1202. The boss 1202 lifts the porous disc 603, so that the denture placed on its upper surface is located above the opening on the dyeing dish 6, so that the irradiation unit irradiates and fixes the denture; after the fixation is completed, the dyeing dish 6 containing the denture is moved into the discharge conveyor 14 again through the cooperation of the elevator 3 and the turntable, and after passing the inspection by the visual inspection unit 15, it is transported out by the discharge conveyor 14.

[0021] Through the cooperation of the impeller 8 and the impregnation dish 6, the impeller 8 disturbs the flow of the impregnation liquid in the impregnation tank 10, enters the impregnation dish 6 through the through hole 602, and is then discharged from the water outlet 601, thereby improving the relative movement between the impregnation liquid and the denture, so that the dyeing factor in the impregnation liquid is constantly in contact with the denture, thereby improving the efficiency of impregnation, and at the same time, the dyeing factor settled at the bottom of the impregnation tank 10 is constantly sucked into the impregnation dish 6 and contacts with the denture, thereby improving the uniformity of impregnation. Through the arrangement of the cover plate 5, the impregnation tank 10, the piston 11 and the pressure regulating device, the pressure regulating device can be used to adjust the air pressure in the space where the denture is located during impregnation. On the one hand, under the action of pressure, the dyeing factor is squeezed and can be more effectively combined with the surface of the denture, thereby improving the efficiency of impregnation. At the same time, under the action of pressure, the movement rate of the dyeing factor in the impregnation liquid is accelerated, so that the dyeing factor can contact with the denture at a higher frequency, further improving the impregnation efficiency.

[0022] Example 2: Please refer to the attached Figure 6 Based on the above embodiment, this embodiment provides another structure of a pressure regulating device: The pressure regulating device includes an air nozzle 17, which penetrates and is fixedly connected to the bottom side wall of the immersion tank 10, and one end of the air nozzle 17 is connected to the space formed by the inner bottom wall of the immersion tank 10 and the bottom wall of the piston 11, and the other end is connected to the air pressure regulating device through the air pipe 18.

[0023] The gas is outputted through the air pressure regulating device, and enters the space formed by the inner bottom wall of the impregnation tank 10 and the bottom wall of the piston 11 through the air pipe 18 and the air nozzle 17 in turn, so that the air pressure is increased, and the piston 11 moves up under the action of the air pressure, thereby compressing the enclosed space of the impregnation tank 10 between the piston 11 and the cover plate 5, and increasing the internal air pressure. When decompression is required, the gas in the space formed by the inner bottom wall of the impregnation tank 10 and the bottom wall of the piston 11 is extracted through the air pressure regulating device, and the piston 11 moves down, thereby achieving a decompression effect.

[0024] Example 3: Please refer to the attached Figure 7 Based on the above embodiment, this embodiment provides another structure of a pressure regulating device: The pressure regulating device includes a support column 19, one end of which is fixedly connected to the inner bottom wall of the workbench 1, and the other end passes through the bottom wall of the immersion tank 10 and is fixedly connected to the bottom wall of the piston 11. The outer wall of the support column 19 is also sleeved with a spring 20, one end of the spring 20 is fixedly connected to the bottom wall of the immersion tank 10, and the other end is fixedly connected to the inner bottom wall of the workbench 1. When the elevator 3 drives the cover plate 5 to press down the immersion tank 10, the tank body of the immersion tank 10 descends, and when the elevator 3 drives the cover plate 5 to rise, the tank body of the immersion tank 10 rises under the action of the spring 20.

[0025] After the cover plate 5 seals the immersion tank 10, the elevator 3 continues to press down, pushing the immersion tank 10 to overcome the force of the spring 20 and move it downward, thereby achieving the relative height increase of the piston 11 in the immersion tank 10, thereby achieving the effect of compressing the enclosed space of the immersion tank 10 between the piston 11 and the cover plate 5, and increasing the internal air pressure. When the elevator 3 drives the cover plate 5 to rise, the body of the immersion tank 10 rises under the action of the spring 20, and the relative height of the piston 11 in the immersion tank 10 moves downward, achieving the expansion of the enclosed space of the immersion tank 10 between the piston 11 and the cover plate 5 to reduce the internal air pressure.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
