Description

Technical Field

[0001] The utility model relates to the technical field of denture firing, in particular to a denture firing furnace provided with an annular material discharging and heat preservation structure. Background Art

[0002] Dentures are what we often call false teeth in our daily lives. There are many materials for dentures, such as plastic teeth, porcelain teeth and metal teeth. In the process of metal teeth production, a firing furnace is needed to fire the dentures in the mold to obtain the finished product.

[0003] In the prior art, a Chinese patent with publication number CN218065915U discloses a novel porcelain powder baking furnace for denture production, comprising a base, a threaded disk rotatably connected to the top of the base, a driving cover connected to the top of the base, a moving groove provided on the driving cover, a threaded block threadedly connected to the threaded disk, the threaded block adapted to the moving groove, a clamping block connected to the threaded block, and four moving grooves and four threaded blocks. The novel porcelain powder baking furnace for denture production can fix the container containing the porcelain powder through the cooperation of the driving cover, the threaded disk, the driving block and the clamping block, thereby ensuring the stability of the porcelain powder during the firing process, the fixing rod can be inserted into the slot to fix the hand wheel to prevent the hand wheel from rotating, thereby fixing the transmission rod, further fixing the threaded disk, and most of the heat can be isolated and blocked inside the heating furnace through the heat insulation layer, reducing heat loss and improving the heating efficiency of the porcelain baking furnace.

[0004] During use, the above-mentioned device moves downward through the heating furnace and covers the firing mold to achieve the purpose of firing. However, in actual use, if multiple teeth are fired continuously, the heating furnace needs to be moved up and down repeatedly, and it takes a long time to replace the dentures that need to be fired. During this process, a large amount of heat in the heating furnace will be dissipated, and subsequent heating will require more energy. Utility Model Content

[0005] The utility model aims to provide a denture firing furnace with an annular discharging and heat preservation structure to solve the problem of excessive heat loss and increased heat consumption in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a denture firing furnace provided with an annular discharging and heat preservation structure, comprising a support base placed horizontally on a table, an operation panel fixedly mounted on the front end of the upper surface of the support base, and further comprising:

[0007] A support column is fixedly installed on the rear end of the upper surface of the support base, and a firing furnace shell is fixedly installed on the upper end of the front side of the support column, and an electric heating coil is fixedly installed inside the firing furnace shell;

[0010] Preferably, a transversely arranged connecting plate is rotatably installed below the carrying turntable, and the connecting plate forms a sliding lifting mechanism with the supporting column through a lifting screw rod rotatably installed inside the supporting column.

[0011] Preferably, a driving roller driven by a motor is rotatably installed on the upper rear side of the support base, and the driving roller is made of rubber material, and the driving roller is squeezed and rubbed against the side of the supporting turntable.

[0012] Preferably, the automatic clamping mechanism comprises a clamping block installed above the placement table, and a limiting slider extending into the interior of the placement table is fixedly installed on the lower surface of the clamping block.

[0013] Preferably, a guide slide bar is installed through the interior of the limit slide block, and the clamping block forms a sliding structure between the limit slide block and the placement table.

[0014] Preferably, a movable magnetic block is installed inside the placement table, and the movable magnetic block forms an elastic telescopic structure with the placement table through a reset spring fixedly installed on the upper surface of the movable magnetic block.

[0015] Preferably, a connecting rod is rotatably installed between the upper surface of the movable magnetic block and the lower surface of the clamping block, and the position of the movable magnetic block corresponds to the position of a fixed column fixedly installed on the upper surface of the support base, and the fixed column and the movable magnetic block magnetically repel each other.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the denture firing furnace with an annular discharge and heat preservation structure adopts a new structural design, and its specific contents are as follows:

[0017] 1. Set up a ring-shaped discharge mechanism to place the dentures to be processed at equal intervals on the circular bearing turntable. After firing, the connecting rod drives the bearing turntable to move downward to realize unloading. Then the driving roller drives the bearing turntable to rotate and quickly switch to the next denture for firing. During this process, the bearing turntable descends a short distance and is replaced quickly, so the heat loss inside the firing furnace is small, achieving the purpose of efficient heat preservation.

[0018] 2. Use the elastic action of the reset spring to push the movable magnetic block downward, so that the movable magnetic block drives the connecting rod on the side to rotate, and use the connecting rod to pull the limit slider, and finally the limit slider drives the clamping block to move to the middle position, so as to achieve the clamping and fixing operation of the firing dish;

[0019] Furthermore, after the carrying turntable moves downward, the magnetic repulsion between the fixed column and the movable magnetic block is utilized to make the movable magnetic block move upward relative to the placement table, thereby causing the movable magnetic block to drive the connecting rod to rotate in the opposite direction, and the connecting rod is utilized to push the clamping block to move outward, thereby loosening the clamping block, making it convenient for the staff to replace the firing dish.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1: Please refer to Figure 1-Figure 3 In order to achieve the purpose of firing dentures, the present embodiment provides the following technical solutions, which specifically disclose: a support base 1 is horizontally placed on a desktop, an operation panel 2 is fixedly installed on the front end of the upper surface of the support base 1, a support column 3 is fixedly installed on the rear end of the upper surface of the support base 1, and a firing furnace shell 4 is fixedly installed on the upper end of the front side of the support column 3, and an electric heating coil 5 is fixedly installed inside the firing furnace shell 4, and an annular discharge mechanism for reducing the discharge speed and assisting in heat preservation is arranged above the support base 1, the annular discharge mechanism includes a carrying turntable 6 with a circular structure, a placing table 7 is fixedly installed on the upper surface of the carrying turntable 6, and a firing dish 8 with a denture mold is placed above the placing table 7, and an automatic clamping mechanism for automatically fixing the firing dish 8 is arranged above the placing table 7, a horizontally arranged connecting plate 9 is rotatably installed below the carrying turntable 6, and the connecting plate 9 forms a sliding lifting mechanism with the supporting column 3 through a lifting screw 10 rotatably installed inside the supporting column 3.

[0030] When using the device, first place the denture to be fired in the firing dish 8, then place the firing dish 8 in the middle position above the placement table 7, then start the internal motor of the supporting column 3, and the Shudie motor drives the lifting screw 10 to rotate. Under the transmission action of the lifting screw 10, the connecting plate 9 drives the supporting turntable 6 to move upward, and finally the firing dish 8 is sent into the firing furnace shell 4, and the electric heating coil 5 is turned on for heating to achieve the purpose of firing.

[0031] Example 2: Please refer to Figure 1-Figure 4 In order to solve the problem of rapid heat loss and increased energy consumption in traditional devices, this embodiment provides the following technical solutions: a ring-shaped discharging mechanism is set to speed up the replacement of staff, thereby reducing heat loss and achieving the purpose of heat preservation. Specifically disclosed: a driving roller 11 driven by a motor is rotatably installed on the upper rear side of the support base 1, and the driving roller 11 is set to be made of rubber material, and the driving roller 11 is squeezed and rubbed with the side of the supporting turntable 6.

[0032] After firing is completed, the lifting screw rod 10 rotates in the opposite direction to drive the connecting plate 9 to move downward, thereby driving the carrying turntable 6 to move downward, and finally moving the carrying turntable 6 to a position corresponding to the driving roller 11. Then, the friction force of the driving roller 11 is used to drive the carrying turntable 6 to rotate ninety degrees, and automatically switch to the next firing dish 8 that needs to be fired. Compared with the traditional replacement method, this process has a short interval time, thereby reducing heat loss and achieving a better insulation effect.

[0033] Example 3: Please refer to Figure 5-Figure 7In order to solve the problem of cumbersome clamping operation of traditional devices, the present embodiment provides the following technical solutions, an automatic clamping mechanism is set, and the firing dish 8 is automatically clamped by the automatic clamping mechanism, which specifically discloses: the automatic clamping mechanism includes a clamping block 13 installed above the placement table 7, and a limit slider 14 extending into the interior of the placement table 7 is fixedly installed on the lower surface of the clamping block 13, a guide slide bar 15 is installed inside the limit slider 14, and the clamping block 13 forms a sliding structure with the placement table 7 through the limit slider 14, a movable magnetic block 16 is installed inside the placement table 7, and the movable magnetic block 16 forms an elastic telescopic structure with the placement table 7 through a reset spring 17 fixedly installed on its upper surface, a connecting rod 18 is rotatably installed between the upper surface of the movable magnetic block 16 and the lower surface of the clamping block 13, and the position of the movable magnetic block 16 corresponds to the position of the fixed column 12 fixedly installed on the upper surface of the support base 1, and the fixed column 12 and the movable magnetic block 16 repel each other magnetically.

[0034] When the carrying turntable 6 moves upward, the squeezing action of the return spring 17 is used to push the movable magnetic block 16 downward, so that the connecting rod 18 on the side of the movable magnetic block 16 pulls the clamping block 13 to move toward the middle (the limiting slider 14 below the clamping block 13 slides outside the guide slide bar 15), so that the clamping block 13 automatically clamps and fixes the firing dish 8. When the carrying turntable 6 moves downward, the magnetic repulsion between the fixed column 12 and the movable magnetic block 16 is used to push the movable magnetic block 16 to move upward relative to the placement table 7, so that the connecting rod 18 pushes the clamping block 13 to the edge position, thereby automatically releasing the clamping of the firing dish 8.
