DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following combines the drawings and embodiments to describe the utility model in detail.

[0026] An efficient porcelain baking furnace for denture production of the utility model, as Figure 1-2As shown, the porcelain furnace body 1 includes a porcelain table 2 and a sealing cover 3. A porcelain space 4 is provided on the porcelain table 2. A rotating device, a heat insulation plate 10, a baking tray 11 and a heating component 12 are arranged in the porcelain space 4. The heat insulation plate 10 can protect the rotating device from being affected by the heating component 12. The rotating device includes a first motor 6, a gear set 7, a fixed rod 8 and a rotating rod 9. The gear set 7 includes a driving gear and driven gears. All four driven gears are engaged with the driving gear. The driving gear is fixedly connected to the first motor 6. A bearing is provided in the center of each driven gear. There are four fixed rods 8, and the fixed rods 8 correspond to the driven gears one by one. Each fixed rod 8 is fixedly connected to the inner ring of the bearing of the driven gear, ensuring that the fixed rod 8 does not rotate with the driven gear. Each gear set 7 is fixedly connected to the baking tray 11 through a rotating rod 9. With the start of the first motor 6, the driving gear drives the driven gears to rotate, so that each baking tray 11 rotates with the gear set 7, enabling the dentures on the baking tray 11 to be evenly heated. The heating component 12 includes a heating coil 13 and a heat insulation ring 14. The heating coil 13 is fixedly connected to the inner side of the heat insulation ring 14, and a plurality of ventilation holes 15 are provided at the intervals between the heating coils 13, so that the air flow in and out will not be blocked.

[0027] As Figure 2-4As shown in the figure, the sealing cover 3 includes a heat dissipation device 31 and a cover body 32. The heat dissipation device 31 includes a wind cover 311 and a rotating assembly 312. The wind cover 311 is provided with a plurality of air outlets 3111. Each air outlet 3111 is provided with an air duct 3113. There is also a second heat dissipation hole 3112. During use, the second heat dissipation hole 3112 is opposite to the first heat dissipation hole 5, which improves the heat dissipation efficiency. The rotating assembly 312 includes a second motor 3121, a coupling 3122, a lead screw 3123, a spiral gear 3124 and a rotating cover 3125. The second motor 3121 is fixedly connected to the cover body 32. The spiral gear 3124 is fixedly connected to one side of the rotating cover 3125. The other side of the rotating cover 3125 is provided with four protruding parts 3126. The four protruding parts 3126 can block all the air outlets 3111 and the second heat dissipation hole 3112. The rotating cover 3125 is in close fit with the wind cover 311. As the second motor 3121 starts, the rotating cover 3125 rotates until the four protruding parts 3126 no longer block the air outlets 3111 and the second heat dissipation hole 3112. The cover body 32 is provided with three installation cavities 33. Fans are provided in the installation cavities 33. The fans blow out airflows. The airflows discharge the heat in the porcelain firing space 4 from the first heat dissipation hole 5, accelerating the heat dissipation speed of the porcelain furnace. The sealing cover 3 can be inserted into the porcelain firing space 4 and is in close fit with the porcelain firing space 4, so that when the porcelain furnace is sintered, the internal space is sealed, and thus the sintering process is more stable. The wind cover 311 and the rotating cover 3125 are made of silicon carbide material. Silicon carbide has excellent high-temperature resistance and can withstand the extremely high temperature inside the porcelain furnace. At the same time, it also has high resistance to some corrosive gases and chemical substances, which can effectively prevent the materials inside the furnace cavity from being corroded, thereby extending the service life of the equipment. The outermost layer of the porcelain furnace body 1 is made of aluminosilicate fiber material, which can effectively insulate heat. Thus, when the porcelain furnace is sintered, people can touch the porcelain furnace body 1 without being scalded, improving the use safety.

[0028] Working principle: First, place the denture to be sintered into the baking tray 11, close the sealing cover 3, set the heating temperature and heating time on the controller 16, and then click the heating button. Then, the second motor 3121 starts. It stops until the protruding part 3126 on the screw cap 3125 blocks the air outlet 3111 and the second heat dissipation hole 3112. Then, the heating coil 13 and the first motor 6 start to operate. The first motor 6 drives all the baking trays 11 to rotate, so that the denture can be sintered in all directions. After the temperature sensor detects that the temperature reaches a certain value, the heating coil 13 will maintain the temperature balance in the porcelain baking space 4. When the sintering time ends, the controller 16 issues a heat dissipation instruction, and the second motor 3121 starts again. It stops until the protruding part 3126 no longer blocks the air outlet 3111 and the second heat dissipation hole 3112. Then the fan starts, and the air flow blows out from the air outlet 3111, taking away the heat in the porcelain baking space 4. The second heat dissipation hole 3112 is communicated with the first heat dissipation hole 5, and the heat is discharged from the first heat dissipation hole 5. Finally, the fan stops, the sealing cover 3 is opened, and the denture is taken out.

[0029] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
