In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be taken on and off by the patient themselves, while removable dentures (commonly known as "removable dentures") can be taken on and off conveniently by the patient.

[0003] The main purpose of denture processing and polishing is to perform fine processing on the denture to improve its adaptability, aesthetics and comfort. Specifically, polishing can remove burrs, sharp edges and residues on the surface of the denture to make its surface smooth and comfortable. Currently, after polishing, the existing dentures need to be manually removed. In addition, since the denture is clamped in a deep position, it is often cumbersome to remove the material, which greatly reduces the subsequent processing efficiency of the denture, has poor applicability, and cannot meet the needs of actual use.

[0042] Furthermore, the material picking and releasing mechanism also includes a first L-shaped clamp 46 and a second L-shaped clamp 47 for clamping the material. The first L-shaped clamp 46 and the second L-shaped clamp 47 are both rotatably installed on the rotating arm 44 through a third connecting shaft 45, and the first L-shaped clamp 46 and the second L-shaped clamp 47 are both provided with a docking rod 48, and the docking rod 48 is hung with a hook spring 49.

[0043] Furthermore, the material picking and discharging mechanism also includes a first limit touch rod 53 and a second limit touch rod 54 for driving the first L-shaped clamp 46 and the second L-shaped clamp 47 to connect for discharging. The first limit touch rod 53 and the second limit touch rod 54 are both threadedly connected to the threaded sleeve 55 and extend out of the outer side of the top plate 52.

[0044] Furthermore, the material picking and discharging mechanism also includes a second gear 57 and a knob 51 for driving the first limit touch rod 53 and the second limit touch rod 54 to adjust the length. The first gear 56 is fixedly connected to the threaded sleeve 55, and the second gear 57 is meshedly connected to the first gear 56. The second gear 57 is rotatably installed in the installation box 50 through a fourth connecting shaft 58.

The second worm gear 60 is rotatably installed in the installation box 50, and one end of the second worm gear 60 is fixedly connected to the knob 51.

[0045] Furthermore, the grinding control mechanism includes a support frame 3 and a rotating base 2 for controlling the steering connection of the grinding head 6. The support frame 3 is installed on the base plate 1 through the rotating base 2. The grinding head 6 is fixedly connected to the output shaft of the grinding motor 5. The grinding motor 5 is fixedly connected to the piston rod of the electric push rod 4. The electric push rod 4 is fixedly installed on the support frame 3.

[0046] Furthermore, a material collecting box 64 for receiving materials is arranged directly below the first limit contact rod 53 and the second limit contact rod 54 , and a rubber material guiding plate 63 for buffering is arranged in the material collecting box 64 .

[0047] Preferably, when the denture is being processed and polished, the electric three-jaw chuck 8 on the three-jaw support seat 7 can be used for limit clamping, and the polishing motor 5 drives the polishing head 6 to rotate accordingly, and the processing and polishing operation of the denture is realized under the action of the electric push rod 4. Figure 2 shown.

[0048] Figure 2The figure also shows the initial state of the material taking and discharging mechanism. After the denture processing is completed, the forward and reverse motor 27 drives the second screw rod 26 to rotate, so that the lifting block 28 moves downward away from the proximity switch 30. At this time, since the lifting block 28 is away from the proximity switch 30, the rotating base 2 correspondingly drives the support frame 3 to rotate 180°, and the electric three-jaw chuck 8 on the three-jaw support seat 7 correspondingly releases the clamping state to move the clamping block away. During the continuous descent of the lifting block 28, the dovetail slider 32 is correspondingly driven to move inside the dovetail slide groove 33. At this time, the dovetail slider 32 Correspondingly, the rotating disk 36 and the connecting sleeve 38 connected to the connecting seat 34 are driven to move downward, so that under the limiting and guiding action of the special-shaped groove 39 opened on the connecting sleeve 38 and the limiting guide rod 42, the connecting sleeve 38 is driven to drive the rotating arm 44 to rotate 90°, that is, when the limiting guide rod 42 is relatively transferred from the second area 41 to the first area 40, the first L-shaped clamp 46 and the second L-shaped clamp 47 on the rotating arm 44 fall onto the three-claw support seat 7, and under the elastic limiting action of the hook spring 49, the clamping and grasping operation of the denture is completed.

[0049] At this time, the forward and reverse motor 27 drives the second screw rod 26 to rotate in the opposite direction, so that the lifting block 28 moves in the direction close to the proximity switch 30. Then, under the limiting and guiding action of the special-shaped groove 39 on the connecting sleeve 38 and the limiting guide rod 42, the connecting sleeve 38 drives the denture clamped on the rotating arm 44 to rotate 90° in the opposite direction. That is, at this time, the limiting guide rod 42 is relatively transferred from the first area 40 to the second area 41. At this time, the denture clamped by the first L-shaped clamp plate 46 and the second L-shaped clamp plate 47 is unfolded under the abutment action of the first limiting contact rod 53 and the second limiting contact rod 54 on the top plate 52. The fallen denture can fall into the collection box 64 for collection under the buffering action of the rubber guide plate 63. There is no need for manual intervention in material collection and processing, which significantly improves work efficiency.

[0050] When in the discharge state, since the lifting block 28 is in contact with the proximity switch 30 again, a new denture can be placed on the three-claw support seat 7 for clamping and fixing, and the rotating base 2 drives the grinding head 6 to rotate to the processing station for processing.

[0051] At the same time, in order to consider the discharge operation of dentures of different sizes, the first L-shaped clamp 46 and the second L-shaped clamp 47 can be adjusted by adjusting the contact length of the first limit touch rod 53 and the second limit touch rod 54. The specific operation method is: the second worm 60 is driven by the knob 51 to rotate and adjust, and the second gear 57 on the fourth connecting shaft 58 is driven to rotate under the meshing connection relationship between the second worm 60 and the second worm wheel 59, so that the threaded sleeve 55 is driven to rotate under the meshing connection relationship between the second gear 57 and the first gear 56, and under the limiting guiding action of the square limit shaft 62, the extension length adjustment of the first limit touch rod 53 and the second limit touch rod 54 can be well realized. It has a wide range of use, strong applicability, and is easy to process and use.

[0052] This automatic material loading and unloading processing method reduces the dependence on manual operation and reduces labor costs. At the same time, it reduces the chances of workers being directly exposed to these potential dangers, reduces the risk of work-related injuries, and improves the safety of the working environment, thereby speeding up production and facilitating the company's production and processing use.

[0054] like Figure 1 to Figure 15 As shown, based on Example 1, this embodiment further includes a ejection mechanism, which is installed at the connection between the three-claw support seat 7 and the vertical plate 31, and is used to eject the processed denture, and is synchronously driven by the material taking and discharging mechanism. The ejection mechanism includes a ejection support plate 9, a wedge block 15 and a driving wheel 16 for ejection connection. The ejection support plate 9 is connected to the inside of the three-claw support seat 7 by a connecting column 10 with limited sliding connection, and the ejection support plate 9 is fixedly connected to the wedge block 15 by the connecting column 10, and one side of the wedge block 15 is adapted to be slidably connected to the driving wheel 16, and the driving wheel 16 is rotatably installed at one end of the driving plate 17, and the driving plate 17 is connected to the three-claw support seat 7 with limited sliding connection.

[0055] Furthermore, the lifting mechanism also includes a Z-shaped sliding plate 12 for lifting limit connection, the Z-shaped sliding plate 12 is fixedly connected to the outer side of the connecting column 10, the Z-shaped sliding plate 12 is limitedly slidably connected to the sliding rod 13, the sliding rod 13 is fixedly installed inside the three-claw support seat 7 through the fixed block 11, and a reset spring 14 is provided at the connection between the Z-shaped sliding plate 12 and the fixed block 11.

[0056] Furthermore, the ejection mechanism also includes a first connecting shaft 20 and a second connecting shaft 22 for driving the driving wheel 16 to move and limit the connection. The driving plate 17 is threaded with a first screw rod 18, and the first screw rod 18 is rotatably connected to the first connecting shaft 20 through a bevel gear pair 19. The first connecting shaft 20 is rotatably connected to the vertical plate 31. The first connecting shaft 20 is rotatably connected to the second connecting shaft 22 through a synchronous belt 21. The second connecting shaft 22 is fixedly connected with a first worm gear 23, and the first worm gear 23 is meshingly connected to the first worm 24. The first worm 24 is rotatably connected to the inside of the vertical plate 31, and the first worm 24 is fixedly connected to one end of the second screw rod 26 through a limiting plate 25.

[0057] Preferably, in the present embodiment, whenever the first L-shaped clamping plate 46 and the second L-shaped clamping plate 47 on the rotating arm 44 are transferred from the top plate 52 to the processing station at the three-claw support seat 7, the forward and reverse motor 27 drives the second screw 26 to rotate, which can correspondingly drive the first worm 24 to rotate synchronously, and the second connecting shaft 22 is driven to rotate under the meshing connection between the first worm 24 and the first worm wheel 23, and the second connecting shaft 22 then drives the first connecting shaft 20 to rotate under the synchronous driving action of the synchronous belt 21, and the first connecting shaft 20 drives the first screw 18 to rotate under the connection relationship of the bevel gear pair 19, so that the driving plate 17 drives the driving wheel 16 to move in the direction close to the wedge block 15 under the threaded connection relationship between the first screw 18 and the driving plate 17. The Z-shaped sliding plate 12 on the connecting column 10 is driven to compress the reset spring 14 under the adaptive sliding connection between the driving wheel 16 and the wedge block 15, and simultaneously drives the ejection support plate 9 to move above the three-claw support seat 7, so as to facilitate the ejection of the processed denture, thereby facilitating the first L-shaped clamping plate 46 and the second L-shaped clamping plate 47 on the rotating arm 44 to perform clamping and grasping operations, without the need for manual intervention in material collection, which significantly improves work efficiency, and when the forward and reverse motors 27 are driven to rotate in the reverse direction, the driving plate 17 correspondingly drives the driving wheel 16 to move in the direction away from the wedge block 15, and at this time, under the elastic action of the reset spring 14, the ejection support plate 9 can be driven to fall into the three-claw support seat 7, thereby facilitating subsequent denture processing operations.

[0058] By combining automatic ejection of materials with rotary material retrieving, the entire retrieving process is made smoother and more continuous, which reduces waiting time and production interruptions, optimizes the production process, and improves production efficiency. At the same time, it reduces the chances of workers directly contacting high-temperature materials after grinding, reduces the risk of work-related injuries, improves the safety of the production environment, and facilitates the company's production and processing use.
