[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a muffle furnace for baking and sintering of ceramic dentures, comprising an outer shell, a rotating shaft is rotatably connected to the inner upper end of the outer shell, a driven gear is fixedly connected to the outer wall upper end of the rotating shaft, a support is fixedly connected to the bottom end of the rotating shaft, four support rods arranged in a ring array are fixedly connected to the bottom end of the support, a placing net is fixedly connected to the bottom end of the four support rods, a protective cover is fixedly connected to the upper end of the outer shell, a motor is fixedly connected to the upper end of the protective cover, and a driving gear is fixedly connected to the output end of the motor.
[0006] Through the above-mentioned scheme, the motor drives the driving gear to drive the driven gear, so that the rotating shaft and the support rotate, and then the ceramic denture on the placing net rotates, which ensures that the ceramic denture can be uniformly heated during baking, avoids the problem of local overheating or insufficient sintering caused by static baking, and enables the ceramic denture to rotate automatically during baking, so that the heat can be more uniformly transmitted to each part of the denture, thereby improving the sintering efficiency and shortening the baking time. The user only needs to start the motor to realize the automatic rotation baking of the ceramic denture, without the need for complex manual operation, which reduces the operation difficulty and labor intensity.
[0007] Further, a heat insulation box is fixedly connected inside the outer shell, and a hearth is fixedly connected inside the heat insulation box.
[0008] Through the above scheme, the main function of the heat insulation box is to reduce the heat conduction of the high temperature inside the furnace to the shell and the surrounding environment, thereby improving the energy utilization efficiency and reducing the heat loss, which helps to maintain the high temperature environment in the furnace and ensures the sintering effect of the ceramic denture. Due to the presence of the heat insulation box, the shell and the surrounding equipment and structure will not be damaged due to the high temperature in the furnace.
[0009] Further, the bottom end of the furnace is fixedly connected with four first mounting grooves arranged in a straight line array, and four first heating pipes are fixedly connected inside the four first mounting grooves.
[0010] Through the above scheme, by arranging multiple heating pipes in the furnace, including the first heating pipes arranged in a straight line array at the bottom and the second heating pipes arranged in a straight line distribution on both sides, multi-point heating of the inside of the furnace is realized, which can more quickly raise the temperature in the furnace and shorten the time to reach the set temperature, thereby improving the heating efficiency.
[0011] Further, the side of the shell is fixedly connected with a control box.

[0015] Further, the bottom end of the shell is fixedly connected with four legs arranged in a rectangular array.
[0016] Through the above scheme, the main function of the legs is to support the weight of the entire furnace, ensuring that the equipment can remain stable during operation. By arranging the four legs in a rectangular array, a stable support structure can be formed to prevent the equipment from shaking or toppling during use.
[0017] Further, the shaft penetrates the heat insulation box and the furnace, and the bracket is rotatably arranged inside the furnace.
[0018] Through the above scheme, by the design of the shaft and the bracket, the ceramic denture to be sintered can be prevented from being placed on the textile net at the top, and can be rotated inside the furnace. This rotational movement helps to ensure uniform heating of the workpiece during sintering and avoid sintering defects caused by local overheating or insufficient heating.
[0019] Further, the driven gear is engaged with the driving gear.
[0020] Through the above scheme, the driving gear is driven to rotate by the motor, and when the driving gear rotates, the teeth thereof are engaged with the teeth of the driven gear, thereby transmitting power and movement to the driven gear.
[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:
[0022] The Mo Fu furnace for baking and sintering of ceramic dentures is driven by the motor to drive the driving gear and further drive the driven gear, so that the rotating shaft and the bracket rotate, and further make the ceramic dentures placed on the placing net rotate, ensuring that the ceramic dentures can be uniformly heated during baking, avoiding the problem of local overheating or insufficient sintering caused by static baking, and enabling the ceramic dentures to automatically rotate during baking, so that heat can be more uniformly transmitted to each part of the dentures, thereby improving the sintering efficiency and shortening the baking time. The user only needs to start the motor to realize automatic rotation and baking of the ceramic dentures, without the need for complex manual operation, thereby reducing the operation difficulty and labor intensity.
