Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic materials, specifically relating to a quick-change ceramic debinding and sintering integrated machine. Background Technology

[0002] Ceramic materials have wide applications in electronics, machinery, chemical industry, aerospace and other fields. Their preparation process usually includes two key steps: debinding and sintering. Therefore, ceramic debinding and sintering integrated machines are needed to process ceramics.

[0003] Existing integrated ceramic debinding and sintering machines typically use a trolley to move ceramics into the furnace cavity for debinding and sintering. However, during operation, it's cumbersome to wait for the previous batch of ceramics to complete debinding and sintering, remove it from the furnace cavity, and unload it from the trolley before placing the next batch onto the trolley and moving it into the furnace cavity for processing. Furthermore, during debinding and sintering, gas is generally supplied to the furnace cavity via pipes located at a specific point within the furnace. This uneven gas distribution, with gas initially accumulating near the pipes, and the low-temperature air supplied to the furnace cavity negatively impacts the furnace temperature, resulting in poor performance. Therefore, we propose a quick-change integrated ceramic debinding and sintering machine. Utility Model Content

An annular track is installed on the top of the base and runs through the furnace body. At least two movable seats are provided above the annular track, and the movable seats are connected to the annular track through a walking mechanism.

[0007] Each of the movable seats is connected to a support plate via a lifting mechanism at its top, and a shelf is stacked on top of the support plate, with ceramics placed on the shelf.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Example 1

[0035] Reference Figure 1-5 This is one embodiment of the present utility model, which provides a quick-change ceramic debinding sintering integrated machine, including a furnace body 4, a control cabinet 7 installed on one side of the furnace body 4, and a controller inside the control cabinet 7, which is either a control motherboard or a PLC logic controller.

[0036] like Figure 1 and Figure 2 As shown, the bottom of the furnace body 4 is connected to the base 1, and a ring track 2 is installed on the top of the base 1. The ring track 2 passes through the furnace body 4. At least two movable seats 8 are provided above the ring track 2. The movable seats 8 are connected to the ring track 2 through a walking mechanism. The walking mechanism includes walking wheels 12 that are rotatably connected to both sides of each movable seat 8. The bottom of the walking wheels 12 is in contact with the ring track 2. In actual use, the operator can move the movable seats 8 along the ring track 2 through the walking wheels 12.

[0037] like Figure 3 , Figure 4 and Figure 5As shown, each movable seat 8 is connected to a support plate 19 via a lifting mechanism. A platform 17 is stacked on top of the support plate 19, and ceramics are placed on the platform 17. The lifting mechanism includes an electric push rod 13 fixed to the top of the movable seat 8, and a U-shaped heat insulation frame 10 is installed at the bottom of the support plate 19. The top of the electric push rod 13 is fixed to the bottom of the U-shaped heat insulation frame 10. The furnace body 4 has a furnace cavity 24 inside, and a feed inlet 11 is opened at the bottom of the furnace cavity 24. In actual use, the operator can move the movable seat 8 along the circular track 2 to below the feed inlet 11, and then control the electric push rod 13 to extend. The electric push rod 13 can push the support plate 19 upward, moving the platform 17 from the feed inlet 11 into the furnace cavity 24, so that the ceramics on the platform 17 are located in the furnace cavity 24 for processing.

[0038] like Figure 3 As shown, a limiting stop 16 is installed on the top edge of the support plate 19. The side of the limiting stop 16 is in contact with the edge of the shelf 17. The limiting stop 16 can limit the shelf 17 so that the shelf 17 will not shift.

[0039] It should be noted that, as Figure 3 As shown, a battery box 29 is installed at the bottom of the movable base 8. The battery inside the battery box 29 is connected to the electric push rod 13 through a wire. The battery inside the battery box 29 can power the electric push rod 13, so that the electric push rod 13 can work normally.

[0040] It should be noted that positioning sensors 28 are installed on both sides of the furnace body 4 near the feed inlet 11. The positioning sensors 28 are connected to the controller in the control cabinet 7 through wires. The position of the moving seat 8 can be detected by the positioning sensors 28. When the moving seat 8 moves to the preset position, the positioning sensors 28 can transmit the data to the controller. The controller will remind the staff through the alarm mechanism such as the buzzer, so that the position of the moving seat 8 will not be deviated.

[0041] A heating mechanism is installed on the inner wall of the furnace cavity 24. The heating mechanism includes a heating groove 26 opened on the inner side wall of the furnace cavity 24. A heating resistance wire 20 is installed inside the heating groove 26. Several temperature sensors 27 are installed inside the furnace cavity 24. The heating resistance wire 20 and the temperature sensors 27 are connected to the controller through wires. In actual use, the temperature inside the furnace cavity 24 can be detected by the temperature sensors 27 and the data is transmitted to the controller. The controller controls the heating power of the heating resistance wire 20 so that when the ceramic is debinding, the controller can control the heating resistance wire 20 to heat the inside of the furnace cavity 24 to the preset temperature to debind the ceramic. After the debinding is completed, the controller can control the heating resistance wire 20 to increase the power so that the temperature inside the furnace cavity 24 reaches the preset sintering temperature to sinter the ceramic.

[0042] It should be noted that an exhaust pipe 5 is installed on the top of the furnace body 4. One end of the exhaust pipe 5 is connected to the furnace cavity 24. During the debinding and sintering process, the binder inside the ceramic will be vaporized by high temperature and discharged into the furnace cavity 24. It will be discharged from the exhaust pipe 5 together with the excess gas inside the furnace cavity 24.

[0043] like Figure 5 As shown, a preheating groove 21 is provided on the side of the furnace body 4. A heat insulation baffle 3 is installed on the side of the furnace body 4, covering the opening of the preheating groove 21. A heat exchange tube 25 is installed inside the preheating groove 21. One end of the heat exchange tube 25 is connected to the gas source through the air inlet pipe 6, and the other end of the heat exchange tube 25 is connected to the gas supply pipe 9. An annular gas guide channel 23 is provided inside the furnace body 4. One end of the gas supply pipe 9 is connected to the annular gas guide channel 23, and an opening is provided at the bottom of the annular gas guide channel 23. There are several nozzles 22, which are connected to the inside of the furnace cavity 24. In actual use, the gas from the external gas source can be transported to the heat exchange tube 25 through the air inlet pipe 6. At this time, part of the heat generated by the heating resistance wire 20 is transferred to the preheating tank 21 to preheat the gas in the heat exchange tube 25. The preheated air can be transported to the annular air guide channel 23 through the air delivery pipe 9, and finally sprayed into the furnace cavity 24 through the nozzles 22 to uniformly replenish the gas inside the furnace cavity 24.

[0044] In use, the staff places the ceramic-containing platform 17 on the support plate 19, and then pushes the movable seat 8 to move it along the circular track 2 to below the feed inlet 11. When the movable seat 8 moves to the preset position, the positioning sensor 28 can detect the position information of the movable seat 8 and transmit the detection data to the controller. The controller reminds the staff through the warning device, and the staff stops moving the movable seat 8. Then, the staff controls the electric push rod 13 to extend, and the electric push rod 13 pushes the support plate 19 upward, pushing the platform 17 from the feed inlet 11 into the furnace chamber 24.

[0045] At this time, the controller controls the heating resistance wire 20 to work, the heating resistance wire 20 heats the furnace cavity 24, and the temperature inside the furnace cavity 24 is detected by the temperature sensor 27 and the detection data is transmitted to the controller. The controller controls the heating resistance wire 20 to heat the temperature inside the furnace cavity 24 to the preset value, and performs glue removal on the ceramic on the platform 17. After the glue removal is completed, the controller controls the heating resistance wire 20 to increase the power and raise the temperature inside the furnace cavity 24 to sinter the ceramic.

[0046] During the debinding and sintering process, an external gas source can be delivered to the heat exchange tube 25 through the air inlet pipe 6. At this time, part of the heat generated by the heating resistance wire 20 is transferred to the preheating tank 21 to heat the heat exchange tube 25. In this way, the gas flowing through the heat exchange tube 25 is preheated by the waste heat of the heating resistance wire 20. Then, the high-temperature gas is delivered to the annular gas guide channel 23 through the gas delivery pipe 9. After that, the high-temperature gas is sprayed into the furnace cavity 24 through the nozzle 22, so that the furnace cavity 24 is evenly filled with gas without affecting the temperature of the furnace cavity 24, thus improving the performance.

[0047] During the sintering process, the worker can place the unsintered ceramic on the platform 17 and place the platform 17 on another support plate 19. At the same time, the worker moves the support plate 19 and the movable seat 8 along the circular track 2 to the waiting area of ​​the furnace body 4. After sintering is completed, the controller controls the heating resistance wire 20 to reduce the power and lower the temperature in the furnace cavity 24 to a safe value. Then, the worker controls the electric push rod 13 to retract, the support plate 19 to move down, and the sintered ceramic is moved out of the furnace cavity 24. Then, the worker moves the movable seat 8 out from under the furnace body 4 and moves the subsequent movable seat 8 to a preset position under the furnace body 4. Then, by extending the electric push rod 13, the ceramic is moved into the furnace cavity 24 for debinding and sintering processing.

[0048] Furthermore, a guide rod 15 is installed on the bottom edge of the support plate 19, and several guide sleeves 14 are installed on the top edge of the movable seat 8. The bottom of each guide rod 15 extends into the guide sleeve 14. Through the cooperation of the guide sleeve 14 and the guide rod 15, the support plate 19 can be guided, so that the support plate 19 remains stable.

[0049] Furthermore, such as Figure 4 As shown, grooves 18 are provided on both sides of the bottom of the shelf 17, which can be used to easily remove the shelf 17 from the support plate 19.
