Description

Technical Field

[0001] This application relates to the field of dental prosthesis processing equipment technology, and in particular to a multi-station ceramic sintering furnace. Background Technology

[0002] In the production process of ceramic dentures, the shaped dentures typically need to be sintered, whereby the chemical materials are sintered at high temperatures to form ceramic dentures. As cosmetic dentistry is currently a hot topic in the dental market, the demand for ceramic dentures is increasing, thus placing higher demands on ceramic sintering furnaces.

[0003] A related multi-station ceramic sintering furnace includes a fixed support, a heating component, and a moving component. The fixed support provides installation space for the heating component and the moving component. The heating component can transport the ceramic prosthesis to be sintered into the heating component. The heating component is activated to sinter the ceramic prosthesis.

[0004] However, existing ceramic sintering furnaces typically employ a single-station design, which cannot meet the needs of large-scale processing. They can only sinter one type of material at a time and cannot accommodate the sintering of multiple materials. This necessitates frequent shutdowns for adjustments, reducing the working efficiency of the ceramic sintering furnace. Utility Model Content

[0005] To reduce the problem of ceramic sintering furnaces being unable to accommodate the sintering of multiple materials, this application provides a multi-station ceramic sintering furnace.

[0006] This application provides a multi-station ceramic sintering furnace, which adopts the following technical solution:

[0007] A multi-station ceramic sintering furnace, comprising:

[0008] A fixed base is fixedly installed on the ground. A rotating cavity is vertically provided on the fixed base, and an installation cavity is vertically provided on the fixed base. The rotating cavity and the installation cavity are connected, and the height of the installation cavity is higher than that of the rotating cavity.

[0009] The heating furnace is fixedly installed on a fixed base. The heating furnace is provided with a heating chamber, which is connected to the installation chamber. The heating tubes are fixedly installed on the inner side wall of the heating chamber. Four sets of heating tubes are symmetrically arranged along the central axis of the heating furnace.

[0010] The movable component is rotatably disposed within the rotating cavity, and the movable component is capable of conveying the material to be sintered into the heating cavity;

[0011] The fixing components are installed on the heating furnace. The fixing components can fix the material to be sintered in the heating chamber. There are four sets of fixing components corresponding to the heating chamber.

[0012] By adopting the above technical solution, the fixed base provides space for the moving components and the heating furnace, the heating furnace provides installation space for the fixed components, the moving components can transport the materials to be sintered to different heating chambers, the fixed components can fix the materials to be sintered in the heating chambers, the heating tubes can quickly heat up and sinter the materials fixed in the heating chambers, and the operators can place different materials into different heating chambers for heating through the moving components, so that the ceramic sintering furnace can perform four different sintering at the same time, reducing the number of downtime adjustment steps for operators and improving the working efficiency of the ceramic sintering furnace.

[0013] Optional, the mobile components include:

[0014] The first motor is vertically fixed at the bottom of the rotating cavity, and the output end of the first motor is perpendicular to the bottom of the rotating cavity and faces upward.

[0015] A drive shaft is vertically fixed to the output end of the first motor.

[0016] A movable frame is fixedly installed at the end of the drive shaft away from the first motor. The periphery of the movable frame is in contact with the inner wall of the rotating cavity. A telescopic hole is vertically provided on the movable frame.

[0017] The fixed end of the hydraulic telescopic rod is fixedly installed at the lower end of the movable frame, and the telescopic end of the hydraulic telescopic rod passes through the telescopic hole.

[0018] The support block has one end fixedly connected to the fixed end of the hydraulic telescopic rod, and the other end of the support block abuts against the bottom of the rotating cavity.

[0019] The positioning block has a vertically positioned groove at its lower end. The positioning block is fitted onto the telescopic end of the hydraulic telescopic rod through the positioning groove. The positioning block also has a fixing groove on its periphery.

[0020] Sintered support, which is fixedly installed on the upper end of the positioning block.

[0021] By adopting the above technical solution, the rotation of the first motor can drive the transmission shaft to rotate synchronously, the rotation of the transmission shaft can drive the moving frame to rotate synchronously around the central axis of the transmission shaft, and the rotation of the moving frame can drive the hydraulic telescopic rod to rotate synchronously. The operator can place the material to be sintered on the sintering support. The positioning block facilitates the operator to position the sintering support on the telescopic end of the hydraulic telescopic rod. At the same time, the positioning block facilitates the fixing component to fix the material to be sintered in the heating chamber. The support block can provide vertical support force for the hydraulic telescopic rod, improving the stability of the hydraulic telescopic rod. The rotation of the hydraulic telescopic rod can drive the positioning block and the sintering support to rotate synchronously, so that the material to be sintered moves on the horizontal plane, thereby moving the material to be sintered to the corresponding heating chamber. The extension of the hydraulic telescopic rod can move along the axis of the hydraulic telescopic rod, thereby moving the material to be sintered to the corresponding heating chamber, which facilitates the fixing component to fix the positioning block and the heating tube to heat and sinter the material.

[0022] Optionally, a rotating groove is horizontally arranged on the heating furnace, and a moving groove is horizontally arranged on the heating furnace. One end of the moving groove is connected to the rotating groove, and the other end of the moving groove is connected to the heating chamber. The fixing components include:

[0023] The second motor is fixedly installed on the periphery of the heating furnace, and the output end of the second motor extends into the rotating slot.

[0024] A bidirectional threaded rod is inserted into a rotating groove. One end of the bidirectional threaded rod is fixedly connected to the output end of the second motor, and the other end of the bidirectional threaded rod is rotatably connected to the bottom of the rotating groove.

[0025] The fixing block has one end fitted onto the bidirectional threaded rod, and the other end slidably disposed in the moving groove. Two sets of fixing blocks are symmetrically arranged along the central axis of the heating chamber.

[0026] By adopting the above technical solution, the rotation of the second motor can drive the bidirectional threaded rod to rotate synchronously. The bidirectional threaded rod allows the two sets of fixing blocks to move in opposite directions or in opposite directions along the length of the bidirectional threaded rod. When the fixing blocks move in opposite directions, they can extend into the heating chamber through the moving groove. One end of the fixing block that extends into the heating chamber is embedded in the fixing groove, thereby achieving the purpose of fixing the material to be heated.

[0027] Optionally, a vertical groove is provided on the fixed base, and a protective door is slidably installed on the groove, the height of which is greater than the height of the mounting cavity.

[0028] By adopting the above technical solutions, the installation of protective doors can effectively isolate the heating chamber from the external environment, reduce heat loss, and improve the safety of operators.

[0029] Optionally, the protective door is equipped with a rotatable latch, and the heating furnace is fixedly equipped with a locking block on the side near the protective door, with the latch and locking block corresponding to each other.

[0030] By adopting the above technical solution, the buckle design makes it easier for staff to operate the protective door to slide along the groove. At the same time, the buckle and the locking block work together to fix the protective door, so that the protective door can be closed securely during the use of the sintering furnace, thus improving the safety of equipment operation.

[0031] Optionally, a temperature sensor is installed inside the heating chamber, and a control panel is fixedly installed around the base. The control panel can display the detection data of the temperature sensor.

[0032] By adopting the above technical solution, the temperature sensor can detect the temperature data in the heating chamber in real time and transmit the temperature data to the control panel, which makes it convenient for operators to monitor and adjust the heating parameters in real time.

[0033] Optionally, the lower end of the support block is provided with multiple sets of support grooves at intervals, and each set of support grooves is rotatably provided with a support wheel.

[0034] By adopting the above technical solution, the setting of the support wheel transforms the sliding friction between the support block and the ground into rolling friction, which significantly reduces the resistance when the support block moves and improves the moving efficiency of the support block and the hydraulic telescopic rod.

[0035] Optionally, the positioning block is made of high-temperature alloy, and the sintered support is made of ceramic.

[0036] By adopting the above technical solutions, the high-temperature alloy setting of the positioning block can reduce the impact of the high temperature of the heating furnace on the positioning block, and at the same time reduce the wear of the positioning block when the fixing component clamps the positioning block, thereby improving the service life of the sintering furnace. The ceramic setting of the sintering support can improve the high temperature resistance of the sintering support, and at the same time reduce the heat conduction and dissipation, thereby improving the working efficiency of the sintering furnace.

[0037] In summary, the present invention provides a multi-station ceramic sintering furnace, which has at least one of the following beneficial technical effects:

[0038] 1. The fixed base provides space for the moving components and the heating furnace, while the heating furnace provides installation space for the fixed components. The moving components can transport the materials to be sintered to different heating chambers, and the fixed components can fix the materials to be sintered in the heating chambers. When the heating tubes are activated, they can quickly generate heat to sinter the materials fixed in the heating chambers. Operators can place different materials into different heating chambers for heating using the moving components, allowing the ceramic sintering furnace to perform four different sintering processes simultaneously. This reduces the number of downtime adjustments required by operators and improves the working efficiency of the ceramic sintering furnace.

[0039] 2. The buckle design facilitates the operation of the protective door by allowing it to slide along the groove. At the same time, the buckle and the locking block work together to fix the protective door, ensuring that the protective door can be securely closed during the use of the sintering furnace, thus improving the safety of equipment operation.

Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0049] Combination Figure 1 , Figure 2 and Figure 4This application discloses a multi-station ceramic sintering furnace, including: a fixed base 31, a heating furnace 32, a moving component 1, and a fixed component 2. The fixed base 31 is fixedly installed on the ground, and a rotating cavity 40 and an installation cavity 41 are vertically installed on the fixed base 31. The rotating cavity 40 and the installation cavity 41 are connected, and the height of the installation cavity 41 is higher than that of the rotating cavity 40. The heating furnace 32 is fixedly installed on the fixed base 31, and a heating cavity 43 is installed on the heating furnace 32. The heating cavity 43 is connected to the installation cavity 41. A heating tube 36 is fixedly installed on the inner wall of the heating cavity 43. Four sets of heating cavities 43 are symmetrically arranged along the central axis of the heating furnace 32. The moving component 1 is rotatably installed in the rotating cavity 40 and can transport the material to be sintered into the heating cavity 43. The fixed component 2 is installed on the heating furnace 32 and can fix the material to be sintered into the heating cavity 43. Four sets of fixed components 2 are correspondingly arranged with the heating cavity 43.

[0050] In this embodiment, the fixed base 31 is rectangular, the rotating cavity 40 is cylindrical, and the mounting cavity 41 is rectangular. A vertically arranged L-shaped slide groove 42 is provided on the fixed base 31. Two sets of slide grooves 42 are symmetrically arranged along the center line of the fixed base 31. A protective door 33, rectangular in shape, is slidably mounted on the slide groove 42. The protective door 33 has a protrusion that embeds into the slide groove 42, allowing it to slide along the length of the slide groove 42. The height of the protective door 33 is greater than the height of the mounting cavity 41. A latch 35 is rotatably mounted on the protective door 33, allowing the operator to apply a sliding force along the slide groove 42 using the latch 35 as a force point. A locking block 34 is fixedly mounted on the side of the heating furnace 32 near the protective door 33. The latch 35 corresponds to the locking block 34. When the operator slides the protective door 33 to its highest point, the operator rotates the latch 35 to engage with the locking block 34. The heating furnace 32 is rectangular, and the heating chamber 43 is cylindrical. A temperature sensor 37 is installed inside the heating chamber 43. A control panel 38 is fixedly installed on the periphery of the fixed base 31. The control panel 38 can display the detection data of the temperature sensor 37, so that the operator can monitor the temperature change inside the heating chamber 43 in real time. The heating tube 36 is U-shaped and can quickly heat the heating chamber 43. The heating principle of the heating tube 36 is the prior art in this application embodiment, so the heating principle of the heating tube 36 will not be specifically described in this application embodiment. The moving component 1 can transport the material to be sintered into the heating chamber 43, and the fixing component 2 can fix the material to be sintered into the heating chamber 43. The moving component 1 and the fixing component 2 work together to allow the operator to control the heating process of different heating chambers 43 separately, so that the multi-station ceramic sintering furnace can be compatible with multi-material sintering.

[0051] In practical use, the operator places the material to be sintered on the moving component 1. The moving component 1 moves to transport the material to be sintered into the designated heating chamber 43. The operator applies force to the buckle 35 to move the protective door 33 along the length of the slide 42 towards the heating furnace 32, so that the protective door 33 blocks the installation cavity 41. The operator rotates the buckle 35 to make the buckle 35 engage with the locking block 34. The operator activates the fixing component 2 corresponding to the heating chamber 43 to fix the material to be sintered into the heating chamber 43. The heating tube 36 starts and heats up quickly to sinter the material. The temperature sensor 37 detects the temperature of the heating furnace 32 in real time and transmits the data to the control panel 38. The operator observes the data through the control panel 38 and controls the power of the heating tube 36 so that different materials are sintered at different heating temperatures.

[0052] Combination Figure 1 and Figure 2 In one specific embodiment, the moving component 1 includes: a first motor 11, a drive shaft 12, a moving frame 13, a hydraulic telescopic rod 14, a support block 15, a positioning block 16, and a sintering support 17; the first motor 11 is vertically fixed at the bottom of the rotating cavity 40, and the output end of the first motor 11 is perpendicular to the bottom of the rotating cavity 40 and upward; the drive shaft 12 is vertically fixed at the output end of the first motor 11; the moving frame 13 is fixed at the end of the drive shaft 12 away from the first motor 11, and the periphery of the moving frame 13 is in contact with the inner wall of the rotating cavity 40. A telescopic hole 46 is vertically provided on the upper part. The fixed end of the hydraulic telescopic rod 14 is fixedly provided on the lower end of the movable frame 13. The telescopic end of the hydraulic telescopic rod 14 passes through the telescopic hole 46. One end of the support block 15 is fixedly connected to the fixed end of the hydraulic telescopic rod 14. The other end of the support block 15 abuts against the bottom of the rotating cavity 40. A positioning groove 48 is vertically provided on the lower end of the positioning block 16. The positioning block 16 is sleeved on the telescopic end of the hydraulic telescopic rod 14 through the positioning groove 48. A fixing groove 49 is provided on the periphery of the positioning block 16. The sintered support 17 is fixedly provided on the upper end of the positioning block 16.

[0053] In this embodiment, the rotation of the first motor 11 drives the transmission shaft 12 to rotate synchronously. The transmission shaft 12 is cylindrical. The rotation of the transmission shaft 12 drives the movable frame 13 to rotate synchronously. The movable frame 13 is cylindrical, and its diameter is the same as the diameter of the rotating cavity 40. The rotation of the movable frame 13 drives the hydraulic telescopic rod 14 to rotate synchronously. The telescopic hole 46 is cylindrical, and its diameter is the same as the diameter of the telescopic end of the hydraulic telescopic rod 14. The support block 15 is cylindrical, and its lower end is provided with multiple sets of support grooves 47 at intervals. Each set of support grooves 47 is rotatably equipped with a support wheel 39. The support wheel 39 can reduce the friction between the support block 15 and the bottom of the rotating cavity 40, making the movement of the hydraulic telescopic rod 14 more stable. The positioning block 16 and the positioning groove 48 are cylindrical, with the diameter of the positioning groove 48 being the same as the diameter of the telescopic end of the hydraulic telescopic rod 14. The fixing groove 49 is annular. The sintering support 17 is composed of multiple stacked cylinders. The positioning block 16 is made of high-temperature alloy, and the sintering support 17 is made of ceramic. The high-temperature alloy can reduce the impact of the high temperature of the heating furnace 32 on the positioning block 16. At the same time, when the fixing component 2 is embedded in the fixing groove 49 to fix the positioning block 16, the high-temperature alloy can reduce the wear between the fixing component 2 and the positioning block 16. The ceramic can improve the high temperature resistance of the sintering support 17 and reduce the heat loss in the heating chamber 43, thereby improving the working efficiency of the sintering furnace.

[0054] In practical use, the staff places the material to be sintered on the sintering support 17. The first motor 11 rotates, driving the transmission shaft 12 and the moving frame 13 to rotate synchronously. The rotation of the moving frame 13 drives the hydraulic telescopic rod 14 to rotate to the lower end of the heating chamber 43. The telescopic end of the hydraulic telescopic rod 14 extends. The extension of the hydraulic telescopic rod 14 drives the positioning block 16 and the sintering support 17 to move along the axis of the hydraulic telescopic rod 14 towards the heating chamber 43. When the positioning block 16 and the sintering support 17 enter the appropriate position, the fixing component 2 is activated and embedded in the fixing groove 49, thereby fixing the sintering support 17 and the positioning block 16.

[0055] Combination Figure 3 and Figure 4In one specific embodiment, a rotating groove 44 is horizontally arranged on the heating furnace 32, and a moving groove 45 is horizontally arranged on the heating furnace 32. One end of the moving groove 45 is connected to the rotating groove 44, and the other end of the moving groove 45 is connected to the heating chamber 43. The fixing component 2 includes: a second motor 21, a bidirectional threaded rod 22, and a fixing block 23. The second motor 21 is fixedly arranged on the periphery of the heating furnace 32, and the output end of the second motor 21 extends into the rotating groove 44. The bidirectional threaded rod 22 passes through the rotating groove 44. One end of the bidirectional threaded rod 22 is fixedly connected to the output end of the second motor 21, and the other end of the bidirectional threaded rod 22 is rotatably connected to the bottom of the rotating groove 44. One end of the fixing block 23 is sleeved on the bidirectional threaded rod 22, and the other end of the fixing block 23 is slidably arranged in the moving groove 45. Two sets of fixing blocks 23 are symmetrically arranged along the central axis of the heating chamber 43.

[0056] In this embodiment, the rotating groove 44 is rectangular, the moving groove 45 is L-shaped, the shorter end of the moving groove 45 is connected to the heating chamber 43, and the longer end of the moving groove 45 is connected to the rotating groove 44. The fixing block 23 is L-shaped, and the thickness of the fixing block 23 is the same as the thickness of the moving groove 45. The bidirectional threaded rod 22 is cylindrical. The two sets of fixing blocks 23 are respectively threaded to the opposite threaded sections on the bidirectional threaded rod 22. The rotation of the output end of the second motor 21 is not affected by the heating furnace 32. The rotation of the output end of the second motor 21 can drive the bidirectional threaded rod 22 to rotate synchronously. The rotation of the bidirectional threaded rod 22 drives the two sets of fixing blocks 23 to move in opposite directions along the length of the rotating groove 44, so that the shorter end of the two sets of fixing blocks 23 passes through the moving groove 45 and extends into the heating chamber 43 and is embedded in the fixing groove 49, thereby achieving the purpose of fixing the sintering support 17 and the positioning block 16 in the heating chamber 43.

[0057] In practical use, when the positioning block 16 and the sintering support 17 are moved to the appropriate position, the operator starts the second motor 21. The rotation of the second motor 21 drives the bidirectional threaded rod 22 to rotate synchronously. The rotation of the bidirectional threaded rod 22 drives the two sets of fixing blocks 23 to move in opposite directions along the length of the rotating groove 44 until the shorter end of the two sets of fixing blocks 23 passes through the moving groove 45 and is embedded in the fixing groove 49, thereby completing the fixing of the positioning block 16.

[0058] It should be noted that the first motor 11, the second motor 21, the hydraulic telescopic rod 14, the temperature sensor 37, and the heating tube 36 are electrically connected to an external power source. The control panel 38 is electrically connected to the first motor 11, the second motor 21, the hydraulic telescopic rod 14, the temperature sensor 37, and the heating tube 36. The control panel 38 can be used to control the extension and retraction of the hydraulic telescopic rod 14, the rotation of the first motor 11 and the second motor 21, the reading of data from the temperature sensor 37, and the control of the heating power of the heating tube 36.

[0059] The implementation principle of this application is as follows: The worker places the material to be sintered on the sintering support 17. The worker places the sintering support 17 and the positioning block 16 on the telescopic end of the hydraulic telescopic rod 14. The worker applies external force to the buckle 35, causing the protective door 33 to move along the length of the slide 42 towards the heating furnace 32. The worker rotates the buckle 35 to engage with the locking block 34. The worker starts the first motor 11, which rotates to drive the transmission shaft 12 and the moving frame 13 to rotate synchronously. The rotating frame 13 moves the hydraulic telescopic rod 14 to a suitable position below the heating chamber 43. The telescopic end of the hydraulic telescopic rod 14 extends, causing the positioning block 16 and the sintering support 17 to move into the heating chamber 43. When the positioning block 16 and the sintering support 17 are moved to the appropriate position, the operator starts the second motor 21. The rotation of the second motor 21 drives the bidirectional threaded rod 22 to rotate synchronously. The rotation of the bidirectional threaded rod 22 drives the two sets of fixing blocks 23 to move in opposite directions along the length of the rotating groove 44. The shorter end of the two sets of fixing blocks 23 passes through the moving groove 45 and is embedded in the fixing groove 49, thereby completing the fixing of the positioning block 16 and the sintering support 17. The operator starts the heating tube 36. The control panel 38 monitors the temperature of the heating chamber 43 in real time through the temperature sensor 37 to ensure that the material is sintered at the predetermined temperature. The operator can accurately place different materials into different heating chambers 43 by controlling the moving component 1 to achieve efficient sintering in multiple batches.
