The first telescopic spring 61, the bottom throw mechanism 7 and the inner throw mechanism 8. The ground surface of the waste water tank 1 is a rough surface. The first rodless cylinder 2 is connected to the right side of the upper part of the waste water tank 1. The first rodless cylinder 2 is slidingly connected with a fixed rod 31, and the left side of the upper part of the waste water tank 1 is also slidably connected with a fixed rod 31. The motor 3 is connected between the sides of the fixed rods 31 that are close to each other, and the lower side of the output shaft of the motor 3 is connected usefully. For the polishing part 4 for grinding and polishing the upper surface of the denture, a first rotating part 5 is rotatably connected between the left and right sides of the lower inner part of the waste water tank 1. The first rotating part 5 is squeeze-fitted with the polishing part 4. The sliding member 6 is slidingly connected to the rear side of the upper part of the rotating member 5. A first telescopic spring 61 is connected between the rear lower side of the middle part of the sliding member 6 and the first rotating member 5. A bottom throwing mechanism is provided on the lower side of the grinding member 4. 7. The bottom polishing mechanism 7 is used to polish the inner bottom surface of the denture. The bottom polishing mechanism 7 is provided with an internal polishing mechanism 8. The internal polishing mechanism 8 is used to polish the inner surface of the denture.

As shown in Figures 1 and 3, the bottom throwing mechanism 7 includes a bottom throwing part 71, a sliding rod 72, a second telescopic spring 73 and a polishing cotton 74. The left and right sides of the middle part of the grinding part 4 are slidingly connected with sliding rods 72 , a bottom throwing piece 71 is connected between the lower sides of the sliding rod 72, and a second telescopic spring 73 is wound between the left and right sides of the upper part of the bottom throwing piece 71 and the underside of the grinding piece 4, and the second telescopic spring 73 is wound around On the adjacent sliding rod 72, the left and right sides of the bottom polishing part 71 are connected with polishing cotton 74. The second telescopic spring 73 exerts a downward force on the bottom polishing part 71, so that the bottom polishing part 71 and the polishing cotton 74 are more accurate. Fits the inner base of the denture.

As shown in Figures 1, 4 and 5, the inner throwing mechanism 8 includes a first polishing part 81, a third telescopic spring 82, a wedge block 83, a first sliding block 84 and a fourth telescopic spring 85. The bottom throwing part 71 The front side of the first sliding block 84 is evenly connected with three first sliding blocks 84 in a sliding manner along the circumferential direction. The first sliding blocks 84 are all slidingly connected with a first polishing member 81. The rear lower side of the first polishing member 81 is connected with a similar first sliding block 84. The third telescopic springs 82 are wound around the blocks 84, and the third telescopic springs 82 are wound around the adjacent first polishing part 81. The lower side of the front part of the bottom polishing part 71 is evenly and slidingly connected with three wedges in the circumferential direction. The block 83 and the wedge-shaped block 83 are both squeeze-fitted with the adjacent first sliding block 84. A fourth telescopic spring 85 is connected between the rear side of the first sliding block 84 and the bottom throwing piece 71. The wedge-shaped block 83 squeezes the third telescopic block 83. A sliding block 84 makes the first polishing member 81 move forward toward the inner side of the denture, and under the action of the third telescopic spring 82, the first polishing member 81 is more closely aligned with the inner side of the denture.

In the initial state, the first rotating member 5 maintains an inclined state with the ground. Since the ground surfaces of the waste water tank 1 are rough surfaces, the friction between the waste water tank 1 and the ground can be increased, making the waste water tank 1 more stable. When the grinding and polishing machine for denture processing is used to grind and polish dentures, first move the sliding part 6 to the back and lower side, the first telescopic spring 61 is compressed, and then place the denture between the sliding part 6 and the first rotating part 5 position, and make the teeth on the denture face upward. Release the sliding part 6, and the sliding part 6 will move forward and upward under the action of the first telescopic spring 61 until the sliding part 6 resists the denture, so that it can pass through The sliding member 6 and the first rotating member 5 clamp and limit the denture, and then start the first rodless cylinder 2, causing the right fixed rod 31 to move downward, so that the motor 3 and the left fixed rod 31 move toward each other. Move downward, driving the polishing part 4 to move downward, and the polishing part 4 will drive the sliding rod 72 to move downward, causing the bottom polishing part 71, the first sliding block 84 and the wedge block 83 to move downward, driving the polishing cotton 74 and the first The polishing piece 81 also moves downward. The bottom polishing piece 71, polishing cotton 74 and wedge block 83 will first contact the denture. Under the squeeze of the denture, the sliding rod 72, bottom polishing piece 71, polishing cotton 74 and The wedge blocks 83 all move upward, the second telescopic spring 73 is compressed, and the second telescopic spring 73 exerts a downward squeezing force on the bottom throw piece 71, so that the bottom throw piece 71 fits the inner bottom surface of the denture better, and also It can make the polishing cotton 74 fit more closely to the inner bottom surface of the denture. When the wedge block 83 moves upward, it will squeeze the first sliding block 84, causing the first sliding block 84 to move to the side away from the center direction of the polishing piece 4, driving the second sliding block 84. A polishing piece 81 moves accordingly, and the fourth telescopic spring 85 is stretched. When the first polishing piece 81 contacts the inner side of the denture, it will slightly move toward the center of the polishing piece 4 under the squeeze of the denture. Move a little, the third telescopic spring 82 is slightly compressed, and the third telescopic spring 82 can exert a squeezing force on the first polishing part 81, so that the first polishing part 81 is more in line with the inner surface of the denture, and the polishing part 4 will continue to Moving downward, when the grinding part 4 contacts the first rotating part 5, it will squeeze the first rotating part 5, causing the first rotating part 5 to rotate forward and downward until the first rotating part 5 remains parallel to the ground. That is, the bottom surface of the polishing part 4 is fitted to the upper surface of the denture placed on the first rotating part 5. At this time, the bottom polishing part 71 and the polishing cotton 74 are fitted to the inner bottom surface of the denture, and the first polishing part 81 is fitted to the denture. On the inner side of the denture, the grinding piece 4 fits the upper surface of the denture, and the grinding and polishing work of the denture can be started. Start the motor 3 so that the output shaft of the motor 3 drives the grinding piece 4 to rotate, so that the grinding piece 4 can be rotated for grinding and polishing. On the upper surface of the denture, the rotation of the polishing part 4 will also drive the bottom polishing part 71, the polishing cotton 74 and the first polishing part 81 to rotate accordingly, so that the inner surface of the denture can be rotated and polished by the bottom polishing part 71 and the polishing cotton 74. On the bottom surface, since the polishing cotton 74 is soft, the polishing cotton 74 can deform appropriately when rotating to adapt to the shape of the denture, and the inner surface of the denture can also be polished and polished through the rotation of the first polishing part 81. In this way, the bottom surface of the denture can be polished. Grind and polish multiple surfaces of the denture at the same time, thereby making it easier for people to use the grinding and polishing machine for denture processing to grind and polish the denture. When the grinding and polishing of the denture is completed, the first rodless cylinder 2 is controlled to make the fixed rod on the right side 31 moves upward, driving the motor 3 and the fixed rod 31 on the left to move upward and reset, driving the polishing part 4 to move upward and reset, thereby making the sliding rod 72, bottom polishing part 71, polishing cotton 74, first polishing part 81, and wedge block 83 and the first sliding block 84 both move upward and reset. After the sliding rod 72 is away from the denture, it will move downward and reset under the action of the second telescopic spring 73, so that the bottom polishing piece 71 and the polishing cotton 74 also move downward and reset. After the wedge block 83 is away from the denture, it will move downward and reset under its own gravity. The first sliding block 84 will drive the first polishing part 81 to a direction close to the center of the polishing part 4 under the action of the fourth telescopic spring 85. After the first polishing part 81 is moved away from the denture, it will be slightly moved to the side away from the center of the polishing part 4 under the action of the third telescopic spring 82, and then the first rodless cylinder 2 and the motor 3 will be closed. Then rotate the first rotating member 5 forward and upward so that it can be reset while maintaining an inclination with the ground again, and then move the sliding member 6 backward and downward. The first telescopic spring 61 is compressed, take out the polished denture, and then release it. The sliding member 6 moves forward and upward again under the action of the first telescopic spring 61. To sum up, people can polish the inner bottom surface of the denture through the bottom polishing member 71 and the polishing cotton 74, and through the wedge-shaped The extrusion fit between the block 83 and the first sliding block 84, and with the cooperation of the third telescopic spring 82, allows the first polishing part 81 to fit the inner surface of the denture, and the first polishing part 81 can polish the denture. The inner surface is ground and polished, so that the purpose of grinding and polishing multiple surfaces of the denture can be achieved at the same time, thereby making it easier for people to grind and polish the denture through the grinding and polishing machine for denture processing.

The right side of the second sliding block 92 is A fifth telescopic spring 93 is connected between the right side and the right side of the grinding piece 4 .

When the polishing part 4 moves downward, it will also drive the second sliding block 92 to move downward, so that the second polishing part 91 also moves downward. When the second polishing part 91 contacts the denture, it will be pressed by the denture. , moves to the side away from the center direction of the polishing part 4, so that the second sliding block 92 moves accordingly, the fifth telescopic spring 93 is compressed, and the fifth telescopic spring 93 can exert a squeezing force on the second polishing part 91 , so that the second polishing part 91 fits the outer surface of the denture better. When the polishing part 4 rotates and polishes the upper surface of the denture, it will also drive the second polishing part 91 to rotate accordingly, so that the second polishing part 91 can be attached to the outer surface of the denture. Combined with grinding and polishing the outer surface of the denture, this can save people the extra step of grinding and polishing the outer surface of the denture, making it easier for people to grind and polish the denture through the grinding and polishing machine for denture processing. After the grinding and polishing of the denture is completed, This will cause the polishing part 4 to move upward and reset, and drive the second sliding block 92 and the second polishing part 91 to also move upward and reset. After the second polishing part 91 is away from the denture, the second sliding block 92 will be under the action of the fifth telescopic spring 93 The polishing part 4 moves downward to the side close to the center direction to reset, driving the second polishing part 91 to move and reset accordingly.

On the second rotating member 103, a water storage tank 106 is connected to the right side of the front lower part of the waste water tank 1. The water storage tank 106 and the water pump 105 are connected through a water pipe. The water pipe is made of soft material and passes between the second rotating member 103 and the extrusion frame 102. The extrusion fit between them, and under the action of the torsion spring 104, allows the hose 101 to continuously swing, so that the debris on the denture can be better washed away.

In the initial state, the water storage tank 106 is filled with water. When polishing the dentures, debris may be generated. These debris may adhere to the dentures. When a large amount of debris accumulates, the grinding and polishing work of the dentures may be affected. , then people can rinse the generated debris through the flushing mechanism 10. When the dentures are polished, people can start the water pump 105, pump the water in the water storage tank 106 through the water pipe into the water pump 105, and then through the hose 101 Spray out, thereby rinsing the dentures, and the water that has rinsed the dentures will flow downward into the waste water tank 1. At the same time, people can also start the second rodless cylinder 107, causing the water pump 105 to move to the left, driving the hose 101 and the second The rotating member 103 moves to the left. When the second rotating member 103 contacts the protrusion on the extrusion frame 102, it will rotate forward under the squeeze of the protrusion on the extrusion frame 102, causing the hose 101 to rotate accordingly. The torsion spring 104 is twisted. When the second rotating member 103 is away from the convex part on the extrusion frame 102, the second rotating member 103 will rotate reversely and reset under the action of the torsion spring 104, causing the hose 101 to rotate reversely. After reset, the water pump 105 will continue to move to the left. When the second rotating member 103 contacts the protrusion on the extrusion frame 102 again, the above steps will be repeated. In this way, the hose 101 will move to the left on one side. Swinging up and down on one side, the dentures can be rinsed more comprehensively, so that the debris on the dentures can be rinsed more cleanly, preventing the debris from affecting the grinding and polishing of the dentures, and saving people the extra step of manually wiping and cleaning the debris. , thus making it easier for people to grind and polish dentures through the grinding and polishing machine for denture processing. After rinsing the debris on the dentures, the second rodless cylinder 107 is controlled to make the water pump 105 move to the right and reset, driving the hose 101 and The second rotating member 103 moves to the right to reset, and then the second rodless cylinder 107 and the water pump 105 are closed.
