Description

Technical Field

[0001] The invention belongs to the technical field of denture production, in particular to an intelligent high-temperature denture sintering furnace. Background Art

[0002] Dentures, commonly known as "false teeth," are a general term for restorations made after partial or complete tooth loss in the upper or lower jaw. Currently, dentures are one of the most effective restoration methods, performing just as well as natural teeth. Their effectiveness and advantages have earned them widespread acclaim, resolving the concerns of countless tooth loss sufferers. During the denture production process, a sintering furnace is used to sinter the dentures, allowing them to be primed with porcelain.

[0003] A Chinese patent with announcement number CN213179411U discloses a denture sintering furnace, including a support table, a sintering furnace shell is fixedly provided on the top of the support table, a mounting plate is embedded and connected on one side of the top of the sintering furnace shell, a sintering belt is fixedly installed on the bottom end of the mounting plate, a heat dissipation channel is opened on the other side of the top of the sintering furnace shell, a cover plate is rotatably connected at the opening at the top of the heat dissipation channel, a track groove is fixedly installed in the middle part of the top of the support table, an electric slider is installed inside the track groove, and the middle part of the top of the insulation table is movably connected to the denture crucible table through a positioning column, and a plurality of matrix-distributed sintering slots are opened on the top of the denture crucible table. Through the provided driving motor, fan blades, cooling plate and cooling cylinder, the driving motor drives the fan blades to rotate and generates airflow when energized, so that the cold air generated by the cooling plate is blown into the surface of the denture crucible table, thereby accelerating the cooling rate after the denture is sintered, effectively improving the production efficiency, and eliminating the need for long waiting times.

[0004] In the current existing technology, when sintering is required, the denture is placed inside the sintering groove on the surface of the denture crucible table and then placed into the sintering furnace for sintering. Although the sintered denture can be automatically transported to the position of the fan blade for cooling, the temperature inside the sintering furnace is relatively high. Since the denture needs to be placed once for each sintering, not only will the hot air inside the sintering furnace be ejected, resulting in heat loss, but the ejected hot air may also easily burn the staff.

[0005] To this end, the present invention provides an intelligent high-temperature denture sintering furnace. Summary of the Invention

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 8 As shown, an intelligent high-temperature denture sintering furnace according to an embodiment of the present invention comprises a storage box 1; a sintering box 2 is fixedly connected to one side wall of the storage box 1, and the sintering box 2 is connected to the storage box 1 through a sealing mechanism; a feeding mechanism is provided in the storage box 1; the feeding mechanism comprises a first motor 112 fixedly connected to the bottom of the storage box 1; the output shaft of the first motor 112 is fixedly connected to a first reciprocating screw rod 111, and both ends of the first reciprocating screw rod 111 are rotatably connected to the first reciprocating screw rod 111 through bearings; the first A reciprocating screw rod 111 is threadedly connected to a base plate 11; two vertical rods 113 are fixedly connected to the inner wall of the end of the storage box 1 away from the first reciprocating screw rod 111, and one end of the base plate 11 is slidably connected to the two vertical rods 113; a plurality of crucible tables 12 are stacked on the base plate 11, and a plurality of placement slots are provided on the crucible tables 12; a distance sensor 13 is fixedly connected to the top inner wall of the storage box 1, and the distance sensor 13 is electrically connected to the first motor 112; a pushing mechanism is provided on the top inner wall of the storage box 1.

[0022] At present, dentures are one of the most effective methods of restoration and can be comparable to natural teeth. During the production process of dentures, a sintering furnace is needed to sinter the dentures so as to perform porcelain baking on the dentures. In the prior art, when sintering is required, the dentures are placed inside the sintering groove on the surface of the denture crucible table 12 and then placed into the sintering furnace for sintering. Although the sintered dentures can be automatically transported to the position of the fan blades for cooling, the temperature inside the sintering furnace is relatively high. Since a denture needs to be placed every time it is sintered, not only will the hot air inside the sintering furnace be ejected, resulting in heat loss, but the ejected hot air can also easily burn the staff. When the loading mechanism provided by the present invention is in use, the dentures are first evenly placed on the crucible table 12, and multiple dentures can be placed on the crucible table 12. Then, the crucible tables 12 are stacked in order on the bottom plate 11. When loading is required, the first motor 112 is turned on, and the output shaft of the first motor 112 drives the first reciprocating screw 111 to rotate, and the first reciprocating screw 111 drives the bottom plate 11 to move upward, and the crucible table 12 is driven to move upward through the bottom plate 11. When the top crucible table 12 moves to the appropriate position, the set value is monitored by the distance sensor 13, and the signal is transmitted to the system through the distance sensor 13. The system controls the first motor 112 to turn off and stop upward transportation, and then opens the sealing mechanism, and pushes the top crucible table 12 into the sintering box 2 through the pushing mechanism, thereby realizing the function of automatic loading.

[0023] like Figure 3 and Figure 7 As shown, the pushing mechanism includes a pushing plate 141; a fixed plate 142 is fixedly connected to the top inner wall of the end of the storage box 1 away from the sintering box 2; a second reciprocating screw 14 is rotatably connected between the fixed plate 142 and the inner wall of the storage box 1 through a bearing, and the push plate 141 is threadedly connected to the second reciprocating screw 14; a first gear 144 is fixedly connected to the end of the second reciprocating screw 14 close to the sintering box 2, and a second motor 146 is fixedly connected to the top inner wall of the storage box 1 through a mounting plate, and the output shaft of the second motor 146 is fixedly connected to a second gear 145, and the second gear 145 is meshed with the first gear 144; two cross bars 143 are fixedly connected to the fixed plate 142 and the inner wall of the storage box 1, and the push plate 141 is slidably connected to the two cross bars 143; a linkage mechanism is also provided on the inner wall of the sintering box 2.

[0024] When the pushing mechanism provided by the present invention is in use, when the top crucible table 12 needs to be transported to the sintering box 2, the second motor 146 needs to be turned on, and the second gear 145 is driven to rotate by the output shaft of the second motor 146, and the first gear 144 is driven to rotate by the second gear 145, and the second reciprocating screw rod 14 is driven to rotate by the first gear 144, and the push plate 141 is driven to move by the second reciprocating screw rod 14, and the push plate 141 moves from the end away from the sintering box 2 toward the sintering box 2, and the top crucible table 12 is pushed into the sintering box 2 by the push plate 141. During the pushing process, the linkage mechanism is pushed by the push plate 141, and under the action of the linkage mechanism, the crucible table 12 is facilitated to pass smoothly, thereby realizing the function of pushing the crucible table 12.

[0025] like Figure 3 As shown, the sealing mechanism includes an electric push rod 162 embedded and fixed in the storage box 1, and the output end of the electric push rod 162 is fixed with a baffle 161; a through hole 16 is provided between the storage box 1 and the sintering box 2; and the baffle 161 cooperates with the through hole 16.

[0026] When the sealing mechanism provided by the present invention is in use, during sintering, the baffle 161 is sealed in the through hole 16, and the baffle 161 is made of heat-insulating material to reduce the heat loss of the sintering box 2. When loading is required, the electric push rod 162 is turned on, and the baffle 161 is driven to move by the output end of the electric push rod 162, and the baffle 161 releases the blockage of the through hole 16. At the same time, the pushing mechanism needs to quickly push the top crucible table 12 into the sintering box 2. After pushing is completed, the through hole 16 needs to be sealed again by the baffle 161. At this time, although some heat will flow into the storage box 1 under pressure, since the storage box 1 is sealed, it will not overflow. At the same time, a small amount of heat flows into the storage box 1, which has the function of preheating the denture and is convenient for the sintering of the denture. An exhaust valve is also installed on one side of the storage box 1. When a lot of hot gas accumulates in the storage box 1, it needs to be discharged.

[0027] like Figure 7 As shown, the linkage mechanism includes two mounting brackets 15 fixed to the inner wall of the storage box 1, and the two mounting brackets 15 are arranged on both sides of the baffle 161; the top ends of the mounting brackets 15 are rotatably connected to the second rotating plate 152 via a rotating shaft; the bottom ends of the mounting brackets 15 are rotatably connected to the first rotating plate 151 via a rotating shaft; the rotating shafts are provided with torsion springs; the first rotating plates 151 are flush with the top crucible table 12; and the second rotating plates 152 are flush with the push plates 141.

[0028] When the linkage mechanism provided by the present invention is in use, although the push plate 141 can realize the function of pushing the crucible table 12, when the push plate 141 moves to the other end of the storage box 1, it stops moving, and at this time the crucible has not reached the specified position. Due to the arrangement of the first rotating plate 151 and the second rotating plate 152, when the push plate 141 moves to the side close to the through hole 16, the push plate 141 will squeeze the second rotating plate 152, and the second rotating plate 152 drives the rotating shaft to rotate, and drives the first rotating plate 151 to rotate through the rotating shaft. As the first rotating plate 151 rotates, the crucible table 12 is squeezed and pushed into the sintering box 2. When the crucible table 12 moves to the set position, the push plate 141 no longer contacts the second rotating plate 152, and then the push plate 141 is moved again to the side away from the through hole 16. Under the action of the torsion spring, the first rotating plate 151 and the second rotating plate 152 are quickly reset.

[0029] like Figure 3 and Figure 5 As shown, a first fan 21 is installed on the top of the sintering box 2, and sintering belts 22 are installed on both side walls of the sintering box 2; a plurality of temperature sensors 27 are installed on the inner wall of the sintering box 2; a third motor 23 is fixedly connected to the top of the sintering box 2, and a first screw rod 24 is fixedly connected to the output shaft of the third motor 23, and a lifting frame 26 is threadedly connected to the first screw rod 24; both ends of the first screw rod 24 are rotatably connected to the sintering box 2 through bearings, and guide rods 25 are fixedly connected to the four corners of the inner wall of the sintering box 2, and the lifting frames 26 are slidably connected to the guide rods 25; a telescopic component is provided on the lifting frame 26.

[0030] The sintering belt 22 provided by the present invention is used to sinter the dentures within the sintering box 2. A first fan 21 facilitates airflow within the sintering box 2, maintaining a uniform temperature within the box. A temperature sensor 27 monitors the temperature within the box 2, facilitating temperature control. After sintering is complete, the third motor 23 is activated. The output shaft of the third motor 23 rotates the first screw 24, which in turn drives the lifting frame 26 downward to the desired position. The telescopic assembly releases support for the crucible table 12, allowing it to drop to the next position.

[0031] like Figure 3 and Figure 8As shown, the telescopic assembly includes two movable plates 261 symmetrically arranged on the lifting frame 26, and the movable plates 261 are slidably connected to the movable plates 261 through a slide groove; two sliding rods 262 are fixedly connected to the inner wall of the slide groove, and springs 263 are sleeved on the outer wall of the slide rod 262; a first electromagnetic block 264 is fixedly connected to the side wall of the movable plate 261, and a second electromagnetic block 265 is fixedly connected to the inner side wall of the slide groove near the first electromagnetic block 264, and the first electromagnetic block 264 and the second electromagnetic block 265 are magnetically attracted.

[0032] When the telescopic assembly provided by the present invention is in use, when the crucible table 12 moves from the storage box 1 to the sintering box 2, the movable plate 261 needs to be extended to support the crucible table 12, and when the crucible table 12 moves from the sintering box 2 to the cooling box 3, the movable plate 261 needs to be retracted to facilitate the falling of the crucible table 12; when retraction is required, by turning on the first electromagnetic block 264 and the second electromagnetic block 265, the two electromagnetic blocks are electromagnetically attracted, and the first electromagnetic block 264 drives the movable plate 261 to retract into the slide groove, and the crucible table 12 slides downward, and then by de-energizing the first electromagnetic block 264 and the second electromagnetic block 265, under the action of the spring 263, the two movable plates 261 are reset to facilitate supporting the next crucible table 12.

[0033] like Figure 5 and Figure 6 As shown, a cooling box 3 is fixed to the bottom of the sintering box 2, and two partitions 31 are provided at the connection between the cooling box 3 and the sintering box 2; the two partitions 31 are rotatably connected to the cooling box 3 through a rotating shaft, and one end of the rotating shaft is fixed to a circular gear 311, and a cylinder 314 is fixed to the outer wall of the cooling box 3, and the output end of the cylinder 314 is fixed to a connecting plate 313, and both ends of the connecting plate 313 are fixed to racks 312, and the gears are engaged with adjacent circular gears 311, and two limit rods 315 are fixed to the bottom of the connecting plate 313, and two limit blocks 316 are fixed to the outer wall of the cooling box 3, and the limit rods 315 slide on the limit blocks 316 respectively.

[0034] When in use, the partition 31 provided by the present invention is used to separate the sintering box 2 and the cooling box 3. During sintering, the two partitions 31 rotate to the horizontal, and the two partitions 31 fit tightly together to prevent heat from flowing to the cooling box 3. When it is necessary to move to the cooling box 3, the lifting frame 26 is moved to the bottom by the first screw 24, and the crucible table 12 is contracted by the movable plate 261 to slide onto the partition 31. By opening the cylinder 314, the connecting plate 313 is driven to move by the output end of the cylinder 314, and the two racks 312 are driven to move by the connecting plate 313, and the adjacent circular gears 311 are driven to rotate by the racks 312, and the rotating shaft is driven to rotate by the circular gear 311, thereby driving the partition 31 to rotate. When the partition 31 rotates, the crucible table 12 slides onto the lifting plate 32, and the partition 31 rotates to the horizontal again, thereby achieving the effect of reducing heat loss.

[0035] like Figure 5 As shown, a second fan 34 is provided on the side wall of the cooling box 3 away from the cylinder 314; a second screw rod 33 is rotatably connected to the cooling box 3 through a bearing, and the second screw rod 33 is connected to the bottom of the first screw rod 24 through a coupling, and a lifting plate 32 is threadedly connected to the second screw rod 33, and the bottom of the guide rod 25 extends through the bottom inner wall of the cooling box 3, and the lifting plate 32 is slidably connected to the guide rod 25.

[0036] When the second screw rod 33 provided by the present invention is in use, when the first screw rod 24 rotates, the second screw rod 33 is driven to rotate in the opposite direction through the coupling, and the pitch of the second screw rod 33 is smaller than that of the first screw rod 24, ensuring that the lifting frame 26 moves to the through hole 16 and the lifting plate 32 moves to the bottom end of the second screw rod 33; when the lifting frame 26 moves to the bottom, the lifting plate 32 moves to the top end of the second screw rod 33 to prevent the lifting plate 32 from being stuck, and then the crucible table 12 and the denture are cooled and dissipated by the fan, and cooled to a suitable position for easy removal, thereby achieving simultaneous cooling and sintering without hindering the continuous sintering work.

[0037] Working principle: First, place the dentures evenly on the crucible table 12. Multiple dentures can be placed on the crucible table 12. Then, stack the crucible tables 12 in order on the base plate 11. When loading is required, turn on the first motor 112, and the output shaft of the first motor 112 drives the first reciprocating screw 111 to rotate, and the first reciprocating screw 111 drives the base plate 11 to move upward, and the crucible table 12 drives the base plate 11 to move upward. When the top crucible table 12 moves to the appropriate position, the set value is monitored by the distance sensor 13, and the signal is transmitted to the system through the distance sensor 13. The system controls the first motor 112 to turn off and stop conveying upward, and then opens the sealing mechanism, and pushes the top crucible table 12 into the sintering box 2 through the pushing mechanism, thereby realizing the function of automatic loading.

[0038] When the top crucible table 12 needs to be transported to the sintering box 2, the second motor 146 needs to be turned on, and the second gear 145 is driven to rotate by the output shaft of the second motor 146, and the first gear 144 is driven to rotate by the second gear 145, and the second reciprocating screw rod 14 is driven to rotate by the first gear 144, and the push plate 141 is driven to move by the second reciprocating screw rod 14. The push plate 141 moves from the end away from the sintering box 2 toward the sintering box 2, and the top crucible table 12 is moved to the sintering box 2 by the push plate 141. Inward pushing, during the pushing process, the push plate 141 will squeeze the second rotating plate 152, and the second rotating plate 152 will drive the rotating shaft to rotate, and the rotating shaft will drive the first rotating plate 151 to rotate. As the first rotating plate 151 rotates, the crucible table 12 is squeezed and pushed into the sintering box 2. When the crucible table 12 moves to the set position, the push plate 141 is no longer in contact with the second rotating plate 152. Then the push plate 141 is moved again to the side away from the through hole 16. Under the action of the torsion spring, the first rotating plate 151 and the second rotating plate 152 are quickly reset.

[0039] After sintering is completed, the third motor 23 needs to be turned on, and the first screw rod 24 is driven to rotate by the output shaft of the third motor 23, and the lifting frame 26 is driven downward by the first screw rod 24 to move to a suitable position, and the first electromagnetic block 264 and the second electromagnetic block 265 are turned on, and the two electromagnetic blocks are electromagnetically attracted, and the first electromagnetic block 264 drives the movable plate 261 to retract into the slide groove, and the crucible table 12 slides down and falls on the partition 31, and the cylinder 314 is turned on, and the output end of the cylinder 314 drives the connecting plate 313 to move, and the connecting plate 313 drives the two racks 312 to move, and the racks 312 drive the adjacent circular gears 311 to rotate, and the circular gear 311 drives the rotating shaft to rotate, thereby driving the partition 31 to rotate. When the partition 31 rotates, the crucible table 12 slides on the lifting plate 32, and the partition 31 rotates to a horizontal position again, thereby achieving the effect of reducing heat loss.

[0040] When the first screw rod 24 rotates, the second screw rod 33 is driven to rotate in the opposite direction through the coupling, and the pitch of the second screw rod 33 is smaller than that of the first screw rod 24, ensuring that the lifting frame 26 moves to the through hole 16 and the lifting plate 32 moves to the bottom end of the second screw rod 33; when the lifting frame 26 moves to the bottom, the lifting plate 32 moves to the top end of the second screw rod 33 to prevent the lifting plate 32 from being stuck, and then the crucible table 12 and the denture are cooled and dissipated by the fan. When the temperature is cooled to a suitable position, it is convenient to remove, thereby achieving simultaneous cooling and sintering without hindering the continuous sintering work.
