Description

Technical Field

[0001] This application relates to the field of dental prosthesis processing technology, and in particular to a dental prosthesis processing device that facilitates efficient and uniform cooling. Background Technology

[0002] Dentures, commonly known as false teeth, are prostheses made after teeth have been lost or extracted to restore functions such as chewing, aesthetics, and speech. The denture manufacturing process includes preliminary examination and evaluation, impression taking, recording jaw position, wax fitting, color selection, final product fabrication, fitting and adjustment, and guidance and maintenance.

[0003] In related technologies, cooling is required at certain stages of denture fabrication, primarily during material processing, especially after mechanical carving or high-temperature treatment. During mechanical carving or precision machining of dentures, the high-speed friction of the cutting tools generates significant heat, potentially leading to material deformation or decreased precision. Therefore, timely cooling via a cooling system (such as spray cooling) is necessary to ensure processing accuracy and material stability. Conventional cooling systems operate in a single mode, easily resulting in uneven cooling of the denture during the cooling process, leading to uneven stress distribution within the denture materials (such as resin, metal, or ceramic). If polymer materials experience excessively rapid localized cooling, the molecular chains cannot fully relax, creating residual internal stress. This stress may induce changes in the material's microstructure, reducing long-term stability and ultimately hindering the long-term use of the denture. Summary of the Invention

[0004] This application provides a denture processing device that facilitates efficient and uniform cooling. The purpose is to optimize the conventional cooling system of dentures. When cooling is required during denture fabrication, the device can perform comprehensive and more uniform cooling of the denture, thereby ensuring the consistency of cooling of various parts of the denture, effectively improving the denture processing effect and enhancing its long-term stability.

[0005] This application provides a dental prosthesis processing device that facilitates efficient and uniform cooling, and adopts the following technical solution:

[0006] A denture processing device for efficient and uniform cooling includes a cooling box, inside which a cooling nozzle for cooling the denture is installed. The cooling nozzle has a corresponding air outlet and is rotatably mounted inside the cooling box. During rotation, the cooling nozzle moves in a circular motion around the denture, and while moving in a circular motion, the air outlet is always aimed at the denture and sprays cold air. A support base is installed at the bottom of the denture in a horizontal direction, and a rotating base is installed below the support base. The rotating base is connected to the cooling nozzle through a horizontal rotating plate, and the cooling nozzle is installed on the top of the rotating plate at the end away from the rotating base.

[0007] By adopting the above technical solution, the cooling nozzles, during their circular motion around the dentures, always maintain an air outlet aimed at the dentures. This allows for the continuous rotation of the cooling nozzles to spray cold air onto different parts of the dentures, resulting in more uniform cooling. Compared to traditional cooling methods that spray cold air onto a fixed location on the dentures, leading to less uniform cooling, this method provides more even cooling of the dentures within the cooling chamber. This significantly improves the cooling effect, reduces the frequency of routine maintenance, ensures consistent cooling across all parts of the dentures, and ultimately enhances the denture manufacturing process and long-term stability.

[0008] Preferably, a drive motor is installed inside the cooling box. The drive end of the drive motor is connected to a drive gear via a corresponding rotating shaft. The drive gear is horizontally arranged, and a driven gear is meshed with one side of the drive gear in a horizontal direction. The drive motor is used to drive the drive gear and the driven gear to rotate. The rotating base includes an integrally connected base and a rotating shaft. The base is horizontally arranged, and the rotating shaft is vertically arranged. The base and the rotating shaft are generally in a "T" shape. The base is integrally connected to the top of the driven gear. During rotation, the driven gear synchronously drives the base and the rotating shaft to rotate. One end of the rotating plate is integrally connected to the rotating shaft, and the end of the rotating plate away from the rotating shaft is connected to the cooling nozzle. The cooling nozzle is located on the top of the rotating plate.

[0009] By adopting the above technical solution, one end of the rotating plate is integrally connected to the rotating shaft, and the end of the rotating plate away from the rotating shaft is connected to the cooling nozzle. The cooling nozzle is located at the top of the rotating plate, so that the rotating shaft drives the rotating plate and the cooling nozzle to rotate synchronously during the rotation process.

[0010] Preferably, while the cooling nozzle moves in a circular motion around the denture, the cooling nozzle also periodically rises and falls in the vertical direction.

[0011] By adopting the above technical solution, the cooling nozzle can cool and lower the temperature of different heights of the denture, further improving the uniformity of the cooling and lowering of the denture, and thus improving the cooling and lowering effect of the denture.

[0012] Preferably, the rotating plate is hollow inside, and a cam is rotatably mounted on one end of the rotating plate near the cooling nozzle. The cam is connected to the cooling nozzle and is used to drive the cooling nozzle to periodically rise and fall in the vertical direction.

[0013] By employing the above technical solution, when the upward-protruding end of the cam rotates to a position below the cooling nozzle, it lifts the cooling nozzle upwards; when the upward-protruding end of the cam rotates to another position, the cooling nozzle begins to descend. By utilizing the cam's rotation to drive the cooling nozzle to periodically rise and fall vertically, the cooling nozzle can cool different heights of the denture, further improving the uniformity of cooling and thus enhancing the overall cooling effect.

[0014] Preferably, a first rotating shaft is installed horizontally at one end of the rotating plate near the rotating seat, and a second rotating shaft is installed horizontally at one end of the rotating plate near the cooling nozzle. The first rotating shaft and the second rotating shaft are connected by a corresponding conveyor belt, and the cam is sleeved on the second rotating shaft.

[0015] By adopting the above technical solution, the first rotating shaft drives the second rotating shaft to rotate synchronously through the conveyor belt during the rotation process. The second rotating shaft drives the corresponding cam to rotate during the rotation process, and then uses the rotation of the cam to drive the cooling nozzle to periodically rise and fall in the vertical direction.

[0016] Preferably, there are two conveyor belts, which are located at the left and right ends of the first rotating shaft and the second rotating shaft, respectively.

[0017] By adopting the above technical solution, the synchronous rotation between the first and second rotating shafts is achieved using two conveyor belts, which helps to ensure the stability of the rotation process between the first and second rotating shafts.

[0018] Preferably, the rotating plate is provided with a first gear and a second gear. The first gear is integrally sleeved on the top of the rotating shaft in the horizontal direction, and the second gear is vertically arranged and meshed with the first gear. The second gear is integrally sleeved on the periphery of the first rotating shaft in the vertical direction. During the rotation of the second gear, the first rotating shaft is synchronously driven to rotate. During the rotation of the first rotating shaft, the second rotating shaft is synchronously driven to rotate through the corresponding conveyor belt.

[0019] By adopting the above technical solution, the first rotating shaft drives the second rotating shaft to rotate synchronously through a corresponding conveyor belt during the rotation process. As the second rotating shaft rotates, the cam rotates synchronously under the drive of the second rotating shaft, thereby using the cam to drive the cooling nozzle to periodically rise and fall in the vertical direction.

[0020] Preferably, a roller is installed vertically inside the rotating plate, the roller is located directly above the cam, and a lifting rod is integrally connected to the roller through a corresponding support seat. The lifting rod is vertically arranged, and the end of the lifting rod away from the roller is integrally connected to the bottom of the cooling nozzle.

[0021] By adopting the above technical solution, the roller plays an auxiliary transition role between the lifting rod and the cam. When the upward-protruding part of the cam rotates to the area below the cooling nozzle, it directly contacts the roller, resulting in a smoother connection between the roller and the cam without any jamming. As the upward-protruding part of the cam passes the roller, it pushes the roller upward. During the upward pushing process, the roller drives the cooling nozzle to rise and fall synchronously through the lifting rod.

[0022] Preferably, a guide sleeve is tightly fitted to the top of the rotating plate, and the lifting rod moves up and down vertically within the guide sleeve.

[0023] By adopting the above technical solution, the guide sleeve limits and guides the lifting rod's movement, and restricts the direction of the lifting rod's movement, thereby effectively ensuring the stability of the lifting rod during vertical movement. This, in turn, helps ensure the stability of the cooling nozzle's cooling effect on the denture, resulting in a better cooling effect on the denture.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. As the cooling nozzles rotate around the dentures, the air outlets remain consistently directed at the dentures. This ensures that as the nozzles rotate, cool air is sprayed onto different parts of the dentures, resulting in more uniform cooling. Compared to traditional cooling methods that spray cool air from a fixed location on the dentures, leading to less uniform cooling, this method provides more even cooling within the cooling chamber. This significantly improves the cooling effect, reduces the frequency of routine maintenance, ensures consistent cooling across all parts of the dentures, and ultimately enhances the quality of denture manufacturing and its long-term stability.

[0026] 2. When the upward-protruding end of the cam rotates to a position below the cooling nozzle, it lifts the cooling nozzle upwards. When the upward-protruding end of the cam rotates to another position, the cooling nozzle begins to descend. By using the cam to drive the cooling nozzle to periodically rise and fall vertically during rotation, the cooling nozzle can cool different parts of the denture at different heights, further improving the uniformity of cooling and thus enhancing the cooling effect.

[0027] 3. The roller acts as an auxiliary transition between the lifting rod and the cam. When the upward-protruding part of the cam rotates to below the cooling nozzle, it directly contacts the roller, resulting in a smoother connection between the roller and the cam without any jamming. As the upward-protruding part of the cam passes the roller, it pushes the roller upwards. During this upward movement, the roller drives the cooling nozzle to rise and fall synchronously via the lifting rod. The guide sleeve limits and guides the lifting rod's movement, restricting its direction and effectively ensuring stability during vertical movement. This, in turn, ensures the stability of the cooling nozzle's cooling effect on the denture, resulting in better cooling performance. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0034] Example:

[0035] This application discloses a dental prosthesis processing device that facilitates efficient and uniform cooling, referring to... Figure 1 This includes cooling box 1, which is responsible for cooling the fabricated denture. (See reference...) Figure 1 and Figure 2 The cooling chamber 1 contains a base, which is fixed inside by corresponding hangers. The dentures are placed on the base for cooling. Cooling nozzles 2 are installed inside the cooling chamber 1 to cool the dentures on the base. These nozzles are connected to external cooling equipment, which supplies cool air to them. Each nozzle has an air outlet. The cooling nozzles 2 are rotatably mounted inside the cooling chamber 1 and rotate around the dentures during this rotation. While rotating, the air outlets on the nozzles are always aligned with the dentures.

[0036] Specifically, refer to Figure 2 and Figure 3 A support base is horizontally mounted at the bottom of the denture base to provide stable support. A rotating seat 3 is mounted below the support base. The rotating seat 3 is connected to a cooling nozzle 2 via a horizontally rotating plate 4. The cooling nozzle 2 is mounted above the end of the rotating plate 4 furthest from the rotating seat 3. During rotation, the rotating seat 3 synchronously drives the rotating plate 4 to rotate, which in turn drives the cooling nozzle 2 to rotate in a circular motion around the dentures on the support base.

[0037] As the cooling nozzle 2 rotates around the dentures, its air outlet remains consistently aligned with the dentures. This allows for the continuous rotation of the cooling nozzle 2, spraying cold air onto different parts of the dentures, thus achieving better cooling uniformity across all areas. Compared to traditional cooling methods that spray cold air onto a fixed location on the dentures, resulting in less uniform cooling, this method provides more even cooling of the dentures within the cooling chamber 1. This significantly improves the cooling effect, reduces the frequency of routine maintenance, ensures consistent cooling across all parts of the dentures, and ultimately enhances the quality of denture manufacturing and its long-term stability.

[0038] Specifically, refer to Figure 2 and Figure 3Inside the cooling box 1, a drive motor 5 is fastened with bolts. A drive gear 6 is connected to the drive end of the drive motor 5 via a corresponding rotating shaft. The drive gear 6 is horizontally positioned, and a driven gear 7 is horizontally meshed on one side of the drive gear 6. The drive motor 5 drives the drive gear 6 and the driven gear 7 to rotate. The rotating base 3 includes an integrally connected base 31 and a rotating shaft 32. The base 31 is horizontally positioned, and the rotating shaft 32 is vertically positioned. The base 31 and the rotating shaft 32 together form a "T" shape. The rotating plate 4 is connected to the rotating shaft, and the base 31 is integrally connected to the top of the driven gear 7. During rotation, the driven gear 7 synchronously drives the base 31 and the rotating shaft 32 to rotate.

[0039] One end of the rotating plate 4 is integrally connected to the rotating shaft 32, and the end of the rotating plate 4 away from the rotating shaft 32 is connected to the cooling nozzle 2. The cooling nozzle 2 is located on the top of the rotating plate 4, so that the rotating shaft 32 drives the rotating plate 4 and the cooling nozzle 2 to rotate synchronously during the rotation process.

[0040] Furthermore, while the cooling nozzle 2 moves in a circular motion around the denture, it also periodically rises and falls vertically. This allows the cooling nozzle 2 to cool different parts of the denture at different heights, further improving the uniformity of cooling and thus enhancing the cooling effect.

[0041] Specifically, refer to Figure 2 and Figure 3 The rotating plate 4 is hollow inside. A cam 8 is rotatably installed at one end of the rotating plate 4 near the cooling nozzle 2. The cam 8 is connected to the cooling nozzle 2. During the rotation, the cam 8 drives the cooling nozzle 2 to periodically rise and fall in the vertical direction.

[0042] When the upward-protruding end of the cam 8 rotates to a position below the cooling nozzle 2, it lifts the cooling nozzle 2 upwards. When the upward-protruding end of the cam 8 rotates to another position, the cooling nozzle 2 begins to descend. By using the cam 8 to drive the cooling nozzle 2 to periodically rise and fall vertically during rotation, the cooling nozzle 2 can cool different positions on the denture, further improving the uniformity of cooling and thus enhancing the cooling effect.

[0043] Specifically, refer to Figure 2 and Figure 3A first rotating shaft 9 is installed horizontally at one end of the rotating plate 4 near the rotating seat 3, and a second rotating shaft 10 is installed horizontally at the other end of the rotating plate 4 near the cooling nozzle 2. The first rotating shaft 9 and the second rotating shaft 10 are connected by a corresponding conveyor belt 11. A cam 8 is sleeved on the second rotating shaft 10. During rotation, the first rotating shaft 9 synchronously drives the second rotating shaft 10 to rotate via the conveyor belt 11. During rotation, the second rotating shaft 10 drives the corresponding cam 8 to rotate, thereby using the rotation of the cam 8 to drive the cooling nozzle 2 to periodically rise and fall in the vertical direction.

[0044] In this embodiment, two conveyor belts 11 are provided, which are located at the left and right ends of the first rotating shaft 9 and the second rotating shaft 10, respectively. The two conveyor belts 11 are used to realize the synchronous rotation between the first rotating shaft 9 and the second rotating shaft 10, which helps to ensure the stability of the rotation process between the first rotating shaft 9 and the second rotating shaft 10.

[0045] Specifically, refer to Figure 2 and Figure 3 The rotating plate 4 is equipped with a first gear 12 and a second gear 13. The first gear 12 is integrally fitted onto the top of the rotating shaft 32 in a horizontal direction, and the second gear 13 is vertically arranged and meshed with the first gear 12. Simultaneously, the second gear 13 is integrally fitted onto the circumference of the first rotating shaft 9 in a vertical direction, and the second gear 13 synchronously drives the first rotating shaft 9 to rotate during its rotation. During its rotation, the first rotating shaft 9 synchronously drives the second rotating shaft 10 to rotate via a corresponding conveyor belt 11. As the second rotating shaft 10 rotates, the cam 8 rotates synchronously under the drive of the second rotating shaft 10, thereby using the cam 8 to drive the cooling nozzle 2 to periodically rise and fall in the vertical direction.

[0046] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 A roller 14 is vertically mounted inside the rotating plate 4, located directly above the cam 8. A lifting rod 15 is integrally connected to the roller 14 via a corresponding support seat, and the lifting rod 15 is vertically positioned. The end of the lifting rod 15 away from the roller 14 is integrally connected to the bottom of the cooling nozzle 2. A through hole is provided at the top of the rotating plate 4 for the lifting rod 15 to pass through.

[0047] The roller 14 acts as an auxiliary transition between the lifting rod 15 and the cam 8. When the upward-protruding part of the cam 8 rotates to below the cooling nozzle 2, it directly contacts the roller 14, resulting in a smoother connection between the roller 14 and the cam 8 without any jamming. As the upward-protruding part of the cam 8 passes through the roller 14, it pushes the roller 14 upward. During the upward pushing process, the roller 14 drives the cooling nozzle 2 to rise and fall synchronously through the lifting rod 15.

[0048] Furthermore, referring to Figure 2 , Figure 3 as well as Figure 4 The top of the rotating plate 4 is secured to the guide sleeve 16 by corresponding fastening bolts. The lifting rod 15 moves up and down vertically within the guide sleeve 16. The guide sleeve 16 limits and guides the movement of the lifting rod 15, restricting the direction of its movement. This effectively ensures the stability of the lifting rod 15 during vertical movement, which in turn helps ensure the stability of the cooling nozzle 2 in cooling the denture, resulting in a better cooling effect.

[0049] The implementation principle of the dental prosthesis processing device according to the embodiments of this application, which facilitates efficient and uniform cooling, is as follows:

[0050] Cooling chamber 1 is responsible for cooling the fabricated dentures. (Refer to...) Figure 1 and Figure 2 The cooling chamber 1 contains a base, which is fixed inside by corresponding hangers. The dentures are placed on the base for cooling. Cooling nozzles 2 are installed inside the cooling chamber 1 to cool the dentures on the base. These nozzles are connected to external cooling equipment, which supplies cool air to them. Each nozzle has an air outlet. The cooling nozzles 2 are rotatably mounted inside the cooling chamber 1 and rotate around the dentures during this rotation. While rotating, the air outlets on the nozzles are always aligned with the dentures.

[0051] Specifically, a support base is horizontally mounted on the bottom of the denture base to provide stable support. A rotating seat 3 is mounted below the support base, and the rotating seat 3 is connected to a cooling nozzle 2 via a horizontally rotating plate 4. The cooling nozzle 2 is mounted above the end of the rotating plate 4 furthest from the rotating seat 3. During rotation, the rotating seat 3 synchronously drives the rotating plate 4 to rotate, which in turn drives the cooling nozzle 2 to rotate in a circular motion around the dentures on the support base.

[0052] As the cooling nozzle 2 rotates around the dentures, its air outlet remains consistently aligned with the dentures. This allows for the continuous rotation of the cooling nozzle 2, spraying cold air onto different parts of the dentures, thus achieving better cooling uniformity across all areas. Compared to traditional cooling methods that spray cold air onto a fixed location on the dentures, resulting in less uniform cooling, this method provides more even cooling of the dentures within the cooling chamber 1. This significantly improves the cooling effect, reduces the frequency of routine maintenance, ensures consistent cooling across all parts of the dentures, and ultimately enhances the quality of denture manufacturing and its long-term stability.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
