Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, and in particular to a thermal stability testing machine for ceramic products. Background Technology

[0002] The thermal stability of ceramic products refers to their ability to withstand rapid temperature changes without cracking or deforming. During the production process of ceramic products, it is necessary to test the thermal stability of ceramic products using a testing machine.

[0003] Existing ceramic product thermal stability testing machines typically heat ceramic products directly on a tray or support. However, this results in uneven heating, leading to temperature differences that affect test accuracy and overall performance. Furthermore, these machines lack a cooling mechanism, requiring the ceramic products to be immersed in cold water for rapid heating and cooling after heating. This process necessitates manual removal of the ceramic products from the heating element and placement in an external cooling system, making it cumbersome. Therefore, we propose a new ceramic product thermal stability testing machine. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A ceramic product thermal stability testing machine includes a base 1, a heating chamber 15 mounted on the top of the base 1, a U-shaped frame 6 mounted on the top of the heating chamber 15, a control cabinet 2 mounted on one side of the U-shaped frame 6, and a controller inside the control cabinet 2, which is one of a control motherboard, a host computer, or a PLC logic controller.

[0029] like Figure 1 and Figure 4 As shown, heating resistance wires 17 are installed on both sides of the interior of the heating box 15, and a temperature sensor 31 is also installed on one side of the interior of the heating box 15. The temperature sensor 31 and the heating resistance wires 17 are connected to the controller through wires. In actual use, the heating resistance wires 17 can heat the interior of the heating box 15, and the temperature sensor 31 can detect the temperature inside the heating box 15. In this way, the controller can keep the interior of the heating box 15 in a preset high temperature environment.

[0030] It should be noted that the heating chamber 15 has a door 16 connected to the side near the opening via a hinge. The door 16 covers the opening of the heating chamber 15, and the other side of the door 16 is connected to the heating chamber 15 via a latch. When heating, the operator can close the door 16 to prevent the heat inside the heating chamber 15 from escaping through the opening.

[0031] like Figure 1 and Figure 2 As shown, the U-shaped frame 6 has a strip mounting plate 3 inside. Both ends of the strip mounting plate 3 are connected to the inner wall of the U-shaped frame 6 through a linear drive module 5. The linear drive module 5 is connected to the controller through wires. In actual use, the linear drive module 5 can control the lifting and lowering of the strip mounting plate 3.

[0032] like Figure 1 and Figure 2 As shown, a rotating shaft 7 is rotatably connected to the bottom of the strip mounting plate 3, and a drive motor 4 is connected to the top of the rotating shaft 7. The drive motor 4 is fixed to the top of the strip mounting plate 3 and is connected to the controller via wires. A connecting frame 12 is provided at the bottom of the rotating shaft 7, and connecting plates 11 are connected to both the upper and lower ends of the connecting frame 12. The top of one of the connecting plates 11 is connected to the bottom of the rotating shaft 7. A receiving groove 22 is provided on one side of the connecting frame 12, and ceramic products are placed inside the receiving groove 22. A feed port 14 is provided at the top of the heating chamber 15. When the linear drive module 5 moves down, the connecting plate 11 and the connecting frame 12 pass through the feed port 14 and extend into the heating chamber 15. In actual use, when the linear drive module 5 moves the connecting frame 12 into the heating chamber 15 through the feed port 14, the drive motor 4 can drive the rotating shaft 7 to rotate, which in turn can drive the ceramic products in the receiving groove 22 to rotate. In this way, the ceramic products will be heated evenly during heating, improving the test accuracy.

[0033] like Figure 1 and Figure 2As shown, a strip-shaped movable plate 9 is fitted on the side of the rotating shaft 7, and a first heat insulation baffle 10 is installed at the bottom of the strip-shaped movable plate 9. When the connecting frame 12 and the connecting plate 11 are moved into the heating box 15, the first heat insulation baffle 10 moves into the feed inlet 14, and the bottom of the strip-shaped movable plate 9 abuts against the top of the heating box 15. The feed inlet 14 can be blocked by the first heat insulation baffle 10, so that the heat inside the heating box 15 will not leak from the feed inlet 14 when it is working.

[0034] It should be noted that, as Figure 3 As shown, a limiting frame 13 is provided on one side of the connecting frame 12. The side of the limiting frame 13 abuts against the edge of the ceramic product. Wedge-shaped grooves 23 are provided on the adjacent surfaces of the two connecting plates 11, and one end of each wedge-shaped groove 23 penetrates through the connecting plate 11. Wedge-shaped blocks 21 are installed at both the upper and lower ends of the limiting frame 13. The wedge-shaped blocks 21 are located in the corresponding wedge-shaped grooves 23. When one end of the wedge-shaped block 21 abuts against the end of the wedge-shaped groove 23, the limiting frame 13 is flush with the connecting frame 12. In actual use, after the worker places the ceramic product in the receiving groove 22, the worker can insert the wedge-shaped blocks 21 at both the upper and lower ends of the limiting frame 13 into the corresponding wedge-shaped grooves 23 and place the limiting frame 13 so that the limiting frame 13 is aligned with the connecting frame 12. This can fix the ceramic product in the receiving groove 22 and prevent the ceramic product from falling off during heating.

[0035] like Figure 1 and Figure 4 As shown, several support legs 25 are installed on the bottom edge of the base 1. The support legs 25 are connected by a shelf 20. A water tank 19 is provided on the top of the shelf 20. A through groove 18 is provided on the bottom of the heating box 15. The bottom of the through groove 18 passes through the water tank 19 and the base 1. The top opening of the water tank 19 is located below the through groove 18. In actual use, the water tank 19 will be filled with cooling water. When the ceramic product is heated to the preset temperature for a certain period of time, it can be moved down by the linear drive module 5 to move the ceramic product into the water tank 19 through the through groove 18, so that the ceramic product can be rapidly cooled and heated for testing.

[0036] like Figure 4 As shown, two fixing blocks 29 are installed at the bottom of the base 1, and a second heat insulation baffle 27 is provided between the two fixing blocks 29. The second heat insulation baffle 27 covers the bottom end of the through groove 18, and the bottom of the base 1 is in contact with the top of the second heat insulation baffle 27. In actual use, the through groove 18 can be blocked by the second heat insulation baffle 27, which can prevent the heat inside the heating box 15 from leaking from the through groove 18 when it is working.

[0037] like Figure 4As shown, connecting blocks 26 are installed at both ends of the bottom of the second heat insulation baffle 27. One of the connecting blocks 26 is connected to the fixed block 29 through a telescopic mechanism 24. The telescopic mechanism 24 is one of an electric push rod, a cylinder, or a hydraulic rod. At least one second guide rod 28 is connected between the two fixed blocks 29. The second guide rod 28 slides through the two connecting blocks 26. The telescopic mechanism 24 is connected to the controller through a wire. In actual use, the connecting block 26 can be pushed to slide along the second guide rod 28 through the telescopic mechanism 24, thereby controlling the position of the second heat insulation baffle 27, which is convenient to use.

[0038] Specifically, in use, the operator places the ceramic product to be tested into the receiving groove 22, then inserts the wedge block 21 on the limiting frame 13 into the corresponding wedge groove 23, and pushes the limiting frame 13 so that the end of the wedge block 21 abuts against the end of the wedge groove 23. At this time, the limiting frame 13 is flush with the connecting frame 12, fixing the ceramic product in the receiving groove 22. Then, the controller controls the linear drive module 5 to move downward, and the linear drive module 5 drives the strip mounting plate 3 to move downward, so that the connecting frame 12 passes through the feed inlet 14 and moves into the heating chamber 15. At the same time, the first heat insulation baffle 10 moves into the feed inlet 14. Then, the chamber door 16 is closed, and then the heating is controlled. The resistance wire 17 operates to heat the ceramic product. During the heating process, the controller drives the motor 4 to rotate the shaft 7, which in turn controls the connecting frame 12 to rotate the ceramic product during heating, ensuring uniform heating. After heating is complete, the operator closes the heating resistance wire 17 via the controller and controls the telescopic mechanism 24 to retract. The telescopic mechanism 24 moves the second heat insulation baffle 27 horizontally, opening the through slot 18. Then, the controller controls the linear drive module 5 to move downward, allowing the connecting frame 12 to carry the ceramic product through the through slot 18 and into the water tank 19 for rapid cooling, thus completing the thermal stability test of the ceramic product.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, two first guide rods 8 are symmetrically installed on the top of the heating box 15. The top of the first guide rods 8 is fixed to the inner top of the U-shaped frame 6, and each first guide rod 8 slides through the strip mounting plate 3. The first guide rods 8 can limit the strip mounting plate 3, so that the strip mounting plate 3 remains stable.

[0040] Furthermore, such as Figure 1 and Figure 2As shown, both ends of the strip-shaped moving plate 9 are slidably sleeved on the first guide rod 8, and each first guide rod 8 is sleeved with a spring 30 on its side. The bottom of the spring 30 is fixed on the top of the strip-shaped moving plate 9, and the top of the spring 30 abuts against the bottom of the strip-shaped mounting plate 3. The spring 30 can be compressed when the strip-shaped mounting plate 3 moves down, and the resulting elastic force can push the strip-shaped moving plate 9, so that the first heat insulation baffle 10 can be moved into the feed inlet 14 and block the feed inlet 14.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
