Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, and in particular to a zirconia denture crystallization furnace. Background Technology

[0002] Zirconia dentures are all-ceramic prostheses used for dental restoration, made from zirconia ceramic blocks. They possess excellent biocompatibility, high strength, and aesthetics, and are widely used in dental restoration. The production process of zirconia dentures includes material preparation, screening, dry pressing, isostatic pressing, and pre-sintering.

[0003] A zirconia crystallization furnace is a device used for sintering zirconia dentures. It employs high-temperature heating to raise zirconia ceramic blocks to a specific temperature, causing them to crystallize. Zirconia crystallization furnaces typically feature uniform temperature distribution and precise temperature control to ensure the quality and performance of zirconia dentures. Common zirconia crystallization furnaces include the Sigma denture furnace and the Bonner Thermal zirconia denture sintering furnace.

[0004] In the prior art, some devices cannot guarantee the stability of the zirconia blank during transportation, causing the blank to easily slide and fall on the device. This not only affects the feeding efficiency but may also damage the blank and increase production costs. At the same time, some devices cannot effectively prevent heat loss and the entry of outside air in terms of sealing, making it difficult to maintain a stable temperature and atmosphere in the heating chamber. Therefore, a zirconia denture crystallization furnace is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a zirconia denture crystallization furnace, which aims to improve the problems of some existing devices having difficulty in stably conveying zirconia blanks and ensuring sealing, thus increasing production costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A zirconia denture crystallization furnace includes a base and a crystallization furnace body. The base is equipped with a feeding mechanism, and the crystallization furnace body is equipped with a gas control mechanism.

[0008] The feeding mechanism includes a motor, which is externally fixedly connected to the inside of the base. A disc is fixedly connected to the drive end of the motor. A spiral protrusion is fixedly connected to the left end of the disc. A cylinder is fixedly connected to the inside of the base. A sliding column is slidably connected to the inner wall of the cylinder. A rack plate is fixedly connected to the right end of the sliding column. The outside of the rack plate is meshed with the outside of the spiral protrusion. A placement plate is fixedly connected to the top of the sliding column. An annular plate is fixedly connected to the top of the placement plate.

[0009] The above technical solution involves setting up a feeding mechanism inside the base, using a motor to drive a disc, which, through the engagement of a spiral protrusion with a rack plate, drives the sliding column and placement disc to rise and fall, thereby achieving automated feeding, improving feeding efficiency, and reducing manual operation intensity. At the same time, a gas control mechanism is set up inside the crystallization furnace to provide a suitable atmosphere for the crystallization of zirconia dentures, which helps to improve the crystallization quality of dentures.

[0010] As a further description of the above technical solution:

[0011] A guide limiting plate is fixedly connected to the right side of the sliding column, and a sliding groove is opened inside the cylinder. The outer wall of the guide limiting plate is slidably connected to the inner wall of the sliding groove.

[0012] The above technical solution ensures that the guide limit plate on the right side of the sliding column cooperates with the sliding groove inside the cylinder to ensure that the sliding column maintains a straight movement during the lifting process, preventing it from tilting or deviating. This improves the stability and accuracy of the feeding process, ensures that the placement tray can accurately reach the designated position, and avoids damage to the dentures due to shaking during transportation.

[0013] As a further description of the above technical solution:

[0014] A buffer pad is fixedly connected to the bottom inner wall of the cylinder, and the bottom side of the sliding column is in contact with the top side of the buffer pad.

[0015] Through the above technical solution, the buffer pad on the inner wall of the bottom of the cylinder plays a buffering role when the sliding column descends to the bottom, effectively reducing the impact force between the sliding column and the bottom of the cylinder, reducing the risk of equipment damage due to frequent impacts, extending the service life of the equipment, and reducing equipment maintenance costs.

[0016] As a further description of the above technical solution:

[0017] The gas control mechanism includes a vacuum pump. The crystallization furnace body has an internal top chamber. The outer wall of the vacuum pump is fixedly connected to the inner wall of the chamber. The top of the vacuum pump is fixedly connected to a suction pipe. The inner wall of the chamber is fixedly connected to an inlet pipe. The output end of the inlet pipe is fixedly connected to a square plate. The bottom end of the square plate is fixedly connected to an outlet hood. The outlet hood has multiple outlet holes inside.

[0018] Through the above technical solution: the vacuum pump in the gas control mechanism extracts air from the heating chamber through the suction pipe to create an oxygen-free or low-oxygen environment, preventing the zirconia denture from being oxidized at high temperatures. The design of the air inlet pipe, square plate, air outlet hood and air outlet hole allows the introduced inert gas to diffuse evenly into the heating chamber, providing a stable and uniform atmosphere for denture crystallization and improving the crystallization quality of the denture.

[0019] As a further description of the above technical solution:

[0020] The square plate is fixedly connected to the outside of the crystallization furnace body. A second motor is fixedly connected to the top of the square plate. A rotating rod is fixedly connected to the drive end of the second motor. A spiral blade is fixedly connected to the bottom of the rotating rod.

[0021] Through the above technical solution, the motor at the top of the square plate drives the rotating rod and the spiral blade to rotate, which further promotes the flow and mixing of gas in the heating chamber and enhances the uniformity of the atmosphere. Compared with relying solely on natural gas diffusion, this method enables zirconia dentures to crystallize under more ideal atmospheric conditions, ensuring that the mechanical properties and biocompatibility of the dentures are effectively improved.

[0022] As a further description of the above technical solution:

[0023] A support plate is fixedly connected to the rear end of the main body of the crystallization furnace. The bottom end of the support plate is fixedly connected to the rear side of the top of the base. A heating chamber is opened inside the main body of the crystallization furnace. A heat insulation layer is fixedly connected to the inner wall of the heating chamber. Multiple heating tubes are fixedly connected to the inner wall of the heating chamber.

[0024] The above technical solution enhances the overall stability and integrity of the equipment by connecting the support plate at the rear end of the crystallization furnace body, ensuring stable and reliable operation. The insulation layer on the inner wall of the heating chamber reduces heat loss, improves energy utilization, and lowers production costs. Multiple heating tubes provide the necessary high-temperature environment for zirconia denture crystallization, ensuring smooth phase transformation.

[0025] As a further description of the above technical solution:

[0026] The bottom of the crystallization furnace body is provided with a feed inlet, and a heat insulation pad is fixedly connected to the bottom inner wall of the feed inlet. A sealing ring is fixedly connected to the top of the placement plate, and the top side of the sealing ring is in contact with the bottom side of the heat insulation pad.

[0027] Through the above technical solution, the heat insulation pad at the bottom of the crystallization furnace body and the sealing ring at the top of the placement plate are tightly fitted together. After the placement plate rises into place, it effectively prevents heat loss and external air from entering the heating chamber, maintains a stable temperature and atmosphere in the heating chamber, creates favorable conditions for the crystallization of zirconia dentures, and helps to improve the quality of dentures.

[0028] As a further description of the above technical solution:

[0029] A display screen is mounted on the front side of the base, and control buttons are provided on the front side of the base;

[0030] Through the above technical solution: the display screen on the front of the base is used to display the operating parameters and status information of the equipment, and the control buttons make it convenient for operators to start or stop the feeding mechanism, gas control mechanism, etc., and set the operating parameters of the equipment, such as temperature, time, gas flow, etc., thereby realizing precise control of the equipment, improving the convenience of operation and the intelligence of equipment operation, and enabling operators to understand the status of the equipment in a timely manner and make adjustments.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, once the motor starts, it drives the disc to rotate. By using the engagement of the spiral protrusion and the rack plate, the circular motion is converted into linear motion, which allows the sliding column to rise smoothly along the inner wall of the cylinder, thereby driving the placement plate to rise. The annular plate on the placement plate can prevent the zirconia denture from sliding or falling during transportation. After reaching the designated position, the sealing ring and the heat insulation pad are in close contact to ensure the sealing of the heating chamber. After the crystallization process is completed, the motor reverses, the placement plate descends, and the bottom of the sliding column contacts the buffer pad for cushioning. The entire loading and unloading process does not require manual direct contact with the high-temperature heating chamber, reducing the risk of burns. At the same time, the automated operation improves work efficiency and reduces labor intensity.

[0033] 2. In this invention, a vacuum pump is installed in the containment chamber. Air is extracted from the heating chamber through the suction pipe to create an oxygen-free or low-oxygen environment, preventing the zirconia denture from oxidizing at high temperatures. An inert gas can be introduced through the inlet pipe. After entering the square plate, the inert gas diffuses evenly into the heating chamber through multiple outlet holes on the outlet hood. Simultaneously, the second motor drives the rotating rod and helical blades to rotate, further promoting gas flow and mixing, making the atmosphere in the heating chamber more uniform and stable. This stable and suitable atmosphere provides favorable conditions for the phase transformation of the zirconia denture, ensuring a uniform and consistent phase transformation, thereby improving the mechanical properties and biocompatibility of the denture and enhancing its quality.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a zirconia denture crystallization furnace, comprising a base 1 and a crystallization furnace body 4. The crystallization furnace body 4 is the core part of the zirconia denture crystallization process. A feeding mechanism 2 is installed inside the base 1. The base 1 serves as the basic support structure for the entire zirconia denture crystallization furnace, playing a crucial role in stabilizing the equipment and providing internal installation space for the feeding mechanism 2, ensuring the stable operation of all components of the feeding mechanism 2. The feeding mechanism 2 includes a motor 201, which is externally fixedly connected to the interior of the base 1. The drive end of motor 201 is fixedly connected to a disc 202. Motor 201 is the power source for the feeding mechanism 2, starting and driving the disc 202 to rotate. The left end of the disc 202 is fixedly connected to a spiral protrusion 203. The disc 202 rotates with the rotation of motor 201. A cylinder 204 is fixedly connected inside the base 1. A sliding column 205 is slidably connected to the inner wall of the cylinder 204. The cylinder 204 provides a sliding track and support for the sliding column 205. A rack plate 206 is fixedly connected to the right end of the sliding column 205. The outer surface of the 06 is meshed with the outer surface of the spiral protrusion 203. The spiral protrusion 203, through meshing with the rack plate 206, converts the circular motion of the disc 202 into the linear motion of the rack plate 206. A guide limiting plate 207 is fixedly connected to the right side of the sliding column 205. A groove 208 is opened inside the cylinder 204. The outer wall of the guide limiting plate 207 is slidably connected to the inner wall of the groove 208. The guide limiting plate 207 and the groove 208 cooperate to guide and limit, ensuring that the sliding column 205 remains linear during sliding. The sliding column 205 is fixedly connected to a placement plate 209 at its top. When the rack plate 206 moves in a straight line, the sliding column 205 moves up and down accordingly, thereby driving the placement plate 209 at its top to rise or fall. The top of the placement plate 209 is fixedly connected to an annular plate 210. The placement plate 209 is used to place zirconia dentures. The annular plate 210 plays a limiting and protective role for the zirconia dentures placed on the placement plate 209, preventing the dentures from sliding or falling off during the rising or falling of the placement plate 209.

[0043] Specifically, the base 1 serves as the basic support structure, providing stability for the entire equipment and providing installation space for the feeding mechanism 2, ensuring the normal operation of the feeding mechanism. The motor 201 serves as the power source for feeding, driving the disc 202 to rotate. The disc 202, in conjunction with components such as the spiral protrusion 203 and the rack plate 206, converts the circular motion into linear motion, thereby causing the sliding column 205 to drive the placement plate 209 to rise and fall, realizing the feeding function. The placement plate 209 is used to place dentures, and the annular plate 210 serves to limit and protect the dentures.

[0044] A buffer pad 212 is fixedly connected to the bottom inner wall of the cylinder 204. The bottom side of the sliding column 205 contacts the top side of the buffer pad 212. When the sliding column 205 descends to the bottom, it contacts the buffer pad 212, which plays a buffering role, reducing the impact force between the sliding column 205 and the bottom of the cylinder 204, avoiding damage to the equipment due to large impact, and extending the service life of the equipment. The bottom of the crystallization furnace body 4 is provided with a feed port. A heat insulation pad 9 is fixedly connected to the bottom inner wall of the feed port. A sealing ring 211 is fixedly connected to the top of the placement plate 209. The top side of the sealing ring 211 contacts the bottom side of the heat insulation pad 9. When the placement plate 209 rises to a certain height, the sealing ring 211 is in close contact with the heat insulation pad 9 on the inner wall of the feed port at the bottom of the crystallization furnace body 4. This can effectively prevent heat loss in the heating chamber 6 and the entry of external air, ensuring the temperature and atmosphere in the heating chamber 6 are stable, and providing a good environment for the crystallization treatment of zirconia dentures.

[0045] Specifically, the buffer pad 212 acts as a buffer when the sliding column 205 descends, reducing the impact force on the equipment and extending its service life. The combination of the sealing ring 211 and the heat insulation pad 9 can prevent heat loss in the heating chamber 6 and the entry of external air, ensuring the stability of the temperature and atmosphere in the heating chamber and providing a good environment for the crystallization treatment of zirconia dentures.

[0046] Reference Figure 1 , Figure 2 and Figure 5 A support plate 3 is fixedly connected to the rear end of the crystallization furnace body 4. The bottom end of the support plate 3 is fixedly connected to the rear top of the base 1. The support plate 3 serves to support and connect, enhancing the stability and integrity between the crystallization furnace body 4 and the base 1. A heating chamber 6 is provided inside the crystallization furnace body 4. The heating chamber 6 is the place where zirconia dentures undergo crystallization treatment. A heat insulation layer 7 is fixedly connected to the inner wall of the heating chamber 6. The heat insulation layer 7 effectively reduces heat loss within the heating chamber 6, maintains the temperature stability within the heating chamber 6, and reduces energy consumption. Multiple heating tubes 8 are fixedly connected to the inner wall of chamber 6. The heating tubes 8 are the heat source for heating chamber 6. They generate heat by passing electricity to provide the high-temperature environment required for the crystallization process of zirconia dentures. A display screen 10 is installed on the front side of the base 1 to display the operating parameters and status information of the zirconia denture crystallization furnace. A control button 11 is set on the front side of the base 1. The operator can start or stop the feeding mechanism 2, the gas control mechanism 5, etc. through the control button 11. The operator can also set the operating parameters of the equipment, such as temperature, time, gas flow rate, etc., to achieve precise control of the equipment.

[0047] Specifically, the support plate 3 enhances the stability and integrity between the crystallization furnace body 4 and the base 1, the heat insulation layer 7 reduces heat loss in the heating chamber 6, maintains stable temperature and reduces energy consumption, the heating tube 8 provides a high-temperature environment for crystallization, the display screen 10 displays equipment operating parameters and status information, and the control button 11 enables precise control of the equipment and facilitates operation.

[0048] The crystallization furnace body 4 is equipped with a gas control mechanism 5, which includes a vacuum pump 502. A receiving chamber 501 is formed on the top side of the crystallization furnace body 4. The outer wall of the vacuum pump 502 is fixedly connected to the inner wall of the receiving chamber 501. A suction pipe 503 is fixedly connected to the top of the vacuum pump 502. The vacuum pump 502 extracts air from the heating chamber 6 through the suction pipe 503, achieving the required vacuum level in the heating chamber 6 and removing oxygen and other impurities. This creates an oxygen-free or low-oxygen environment for the crystallization treatment of zirconia dentures, preventing oxidation of the dentures at high temperatures. An air inlet pipe 504 is fixedly connected to the inner wall of the receiving chamber 501, providing installation space for components such as the vacuum pump 502 and the air inlet pipe 504. The air inlet pipe 504 is used to introduce inert gas into the heating chamber 6. A square plate 505 is fixedly connected to the output end of the air inlet pipe 504. The external fixed connection of 5 is to the inside of the crystallization furnace body 4. The bottom end of the square plate 505 is fixedly connected to the gas vent 506. The gas vent 506 has multiple gas vents 507 inside. The gas vent 506 can evenly diffuse the inert gas flowing from the square plate 505 into the heating chamber 6 through the gas vents 507, making the atmosphere in the heating chamber 6 more uniform and providing a stable and uniform crystallization environment for the zirconia denture. The top of the square plate 505 is fixedly connected to the motor 508. The drive end of the motor 508 is fixedly connected to the rotating rod 509. The bottom of the rotating rod 509 is fixedly connected to the spiral blade 510. When the motor 508 rotates, the rotating rod 509 transmits power to the spiral blade 510, enabling the spiral blade 510 to rotate, promoting the flow and mixing of gas in the heating chamber 6, improving the uniformity of the atmosphere, and ensuring that the zirconia denture is crystallized in a stable and uniform atmosphere.

[0049] Specifically, vacuum pump 502 extracts air from heating chamber 6 through suction pipe 503 to create an oxygen-free or low-oxygen environment to prevent denture oxidation. Inert gas is introduced through intake pipe 504, and gas is diffused evenly through exhaust hood 506 to make the atmosphere uniform. Motor 2 508, rotating rod 509 and spiral blade 510 work together to promote gas flow and mixing, ensuring that denture crystallizes in a stable and uniform atmosphere.

[0050] Working principle: When crystallization treatment of zirconia dentures is required, the operator can start the feeding mechanism 2 through the control button 11 on the front of the base 1. The control button 11 issues a command, causing the motor 201 fixedly connected inside the base 1 to start working. The drive end of the motor 201 drives the disc 202 to rotate. Since the left end of the disc 202 is fixedly connected to the spiral protrusion 203, and the spiral protrusion 203 meshes with the rack plate 206, the rotation of the disc 202 will be converted into the linear motion of the rack plate 206. The rack plate 206 is fixedly connected to the sliding column 205, so the sliding column 205 will move upward along the inner wall of the cylinder 204. As the sliding column 205 rises, the placement plate 209 fixedly connected to its top also rises. The annular plate 210 on the placement plate 209 can be used to place zirconia dentures. When the placement plate 209 rises to a certain height, the sealing ring 211 on the placement plate 209 will come into close contact with the heat insulation pad 9 on the inner wall of the bottom feed port of the crystallization furnace body 4 to ensure the sealing of the heating chamber 6. After the crystallization process is completed, the motor 201 reverses and drives the placement plate 209 to descend. When the sliding column 205 descends to the bottom, it will come into contact with the buffer pad 212 on the inner wall of the bottom of the cylinder 204 to play a buffering role and avoid the equipment from being subjected to a large impact.

[0051] The vacuum pump 502 inside the internal chamber 501 of the crystallization furnace body 4 is started to work. The vacuum pump 502 extracts the air from the heating chamber 6 through the suction pipe 503 to achieve the required vacuum level. When inert gas needs to be introduced, it is introduced through the inlet pipe 504. The output end of the inlet pipe 504 is connected to the square plate 505. After the inert gas enters the square plate 505, it will diffuse evenly into the heating chamber 6 through multiple air outlets 507 on the air outlet hood 506 at its bottom. At the same time, the motor 508 fixed on the top of the square plate 505 is started, and its drive end drives the rotating rod 509 to rotate. The spiral blades 510 at the bottom of the rotating rod 509 rotate accordingly, so that the gas entering the heating chamber 6 can be more evenly distributed, ensuring that the zirconia denture is crystallized in a stable and uniform atmosphere.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
