Description

Technical Field

[0001] This utility model relates to the field of crack prevention testing technology, specifically a ceramic heating rod resistance crack prevention testing device. Background Technology

[0002] Ceramic heating elements are electrothermal components with ceramic materials at their core. They convert electrical energy into heat energy through the resistance effect, and are characterized by high efficiency and durability. They are widely used in industrial equipment, household appliances, and emerging consumer electronics. During factory testing, ceramic heating elements typically undergo resistance and crack resistance testing, as this performance is a core indicator determining their service life and safety. The core of resistance and crack resistance testing is to observe the mechanical response of the material or structure during crack initiation, propagation, and eventual failure by simulating stress concentration under actual working conditions (such as tension, bending, and impact). Therefore, resistance and crack resistance testing equipment is required to test and inspect the heating elements.

[0003] Existing resistance crack prevention testing devices for ceramic heating rods typically only involve simply compressing the ceramic rod to visually observe whether it breaks. However, in actual production, due to the large number of heating rods shipped, automated production lines are needed for rapid crack prevention testing. Traditional crack prevention testing devices only perform simple compression load testing, and their rapid water flow testing capability is relatively insufficient, resulting in relatively low testing efficiency. Furthermore, they cannot adjust the testing intensity according to the different models and strengths of the heating rods, leading to relatively insufficient testing accuracy and applicability. Therefore, we propose a resistance crack prevention testing device for ceramic heating rods to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 A ceramic heating rod resistance and crack prevention testing device includes a crack resistance testing platform 1, and a support frame 2 is provided on the top of the crack resistance testing platform 1;

[0028] The top of the support frame 2 is provided with a lifting control cylinder 3, the bottom of the lifting control cylinder 3 is provided with a lifting test plate 4, the bottom of the lifting test plate 4 is provided with a test strength sensor 5 and a support spring 6, and the bottom of the test strength sensor 5 and the support spring 6 is provided with an integrally formed crack resistance detection component 7.

[0029] The top of the crack resistance test bench 1 is provided with a flow guiding and limiting platform 8, the middle of the flow guiding and limiting platform 8 is provided with a detection transmission disk 9, the detection transmission disk 9 is evenly distributed with flow guiding baffle platforms 10, and the side of the detection transmission disk 9 is provided with a drive motor 11.

[0030] The beneficial effects of this solution are as follows: The lifting test plate 4 is raised and lowered by the operating lifting control cylinder 3. A test strength sensor 5 and a support spring 6 are installed at the bottom of the test plate 4. The support spring 6 provides elastic protection during resistance testing to prevent damage from excessive pressure. The heating rod crack resistance detection component 7 can be moved downwards and then rolled to perform resistance testing on the heating rod, making the testing quick and convenient. Simultaneously, the test strength sensor 5 can perform pressure load testing, resulting in high accuracy and good adaptability in resistance measurement. The heating rods can be rolled down sequentially on the flow-guiding and limiting platform 8 under gravity. The drive motor 11 drives the rotating detection transmission disk 9, and the heating rods are sequentially guided onto the detection transmission disk 9, where they are supported and rotated upwards. They are separated by the flow-guiding baffle platform 10. During this support process, the crack resistance detection component 7 performs compression resistance testing on the heating rods, resulting in high testing efficiency and convenience. This automates and rapidly measures resistance and crack resistance, achieving high measurement efficiency. Furthermore, the testing strength can be adjusted according to different models, making it highly practical and accurate in resisting resistance.

[0031] Furthermore, multiple support springs 6 are evenly distributed in a ring shape around the test strength sensor 5, and the support springs 6 are installed between the lifting test plate 4 and the crack resistance detection component 7.

[0032] By setting the support springs 6 to be evenly distributed in a ring shape around the strength sensor 5, stable and uniform elastic support can be provided, and the anti-crack detection component 7 has a good resistance support effect.

[0033] Furthermore, a PLC controller 12 is provided on the side of the crack resistance test bench 1. The output terminal of the PLC controller 12 is electrically connected to the input terminal of the test strength sensor 5 and the lifting control cylinder 3, respectively.

[0034] By setting up a PLC controller 12, which is electrically connected to the input terminals of the intensity sensor 5 and the lifting control cylinder 3 respectively, the switching operation of the intensity sensor 5 and the lifting control cylinder 3 can be stably controlled. Thus, the lifting and lowering of the lifting control cylinder 3 can be adjusted according to the pressure intensity of the intensity sensor 5, making it convenient to adjust the pressure intensity of the device and easy to operate.

[0035] Furthermore, the crack resistance testing component 7 includes a support plate 71 and a crack resistance extrusion roller 72. The crack resistance extrusion roller 72 is installed at the bottom of the support plate 71. The support plate 71 is fixedly installed at the bottom of the test strength sensor 5 and the support spring 6. The crack resistance extrusion roller 72 is located directly below the test strength sensor 5 and directly above the test transmission disk 9.

[0036] The crack resistance testing component 7 includes a support plate 71 and a crack resistance extrusion roller 72. The support plate 71 can support the bottom of the test strength sensor 5 and the support spring 6, and can be flexibly suspended for installation. It also supports the crack resistance extrusion roller 72. The crack resistance extrusion roller 72 is located directly above the test transmission disc 9. When the test transmission disc 9 drives the heating rod, the crack resistance extrusion roller 72 can extrude and extrude resistance for testing. The rolling extrusion facilitates the conveyor belt and resistance testing, resulting in high testing efficiency.

[0037] Furthermore, the top of the flow guiding and limiting platform 8 is inclined, and a test installation port 13 is opened in the middle of the flow guiding and limiting platform 8. The detection transmission disk 9 is rotatably connected to the test installation port 13, and the flow guiding baffle platform 10 at the top extends out of the test installation port 13.

[0038] By setting the top of the flow guiding and limiting platform 8 to be inclined, the heating rods can be arranged and transported in sequence according to gravity. During the falling and transporting process, the detection transmission plate 9 lifts them up for detection, and then they fall back onto the flow guiding and limiting platform 8 to complete the detection. Multiple heating rods can be tested for resistance in sequence, which has high detection efficiency. The test installation port 13 facilitates the installation of the detection transmission plate 9 and has a good installation load-bearing effect. A baffle plate is provided inside the test installation port 13 to prevent the heating rods from falling into the test installation port 13. The transmission and transport of the detection transmission plate 9 is stable and convenient to use.

[0039] Furthermore, the bottom of the drive motor 11 is fixedly installed on the top of the crack resistance test bench 1, and the top of the flow guiding and limiting platform 8 is provided with a rod limiting frame 14, which is inclined in relation to the top of the flow guiding and limiting platform 8.

[0040] By setting the rod limiting frame 14, the heating rods arranged and conveyed on the top of the flow guiding and limiting platform 8 can be limited, so that both ends of the heating rods are limited by the rod limiting frame 14. When rolling down, the flow is stable, not easy to block or deviate, and the falling stability is good.

[0041] Furthermore, the flow guide baffle platform 10 is a U-shaped limiting frame, with multiple U-shaped limiting frames corresponding to the detection transmission disc 9 as the axis;

[0042] By setting the flow guide baffle platform 10 as a U-shaped limiting frame, the heating rods are sequentially arranged and guided onto the detection transmission plate 9. A single heating rod can be conducted between two flow guide baffle platforms 10 and supported by the detection transmission plate 9. When the detection transmission plate 9 squeezes the heating rod, it is not easy to collide with the flow guide baffle platform 10, so that the heating rod can be stably resisted and the resistance and crack prevention test effect is good.

[0043] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0044] Working principle: A support frame 2 is provided on the top of the crack resistance test bench 1, which can support the lifting and regulating cylinder 3. When the lifting and regulating cylinder 3 is raised and lowered, it can drive the lifting test plate 4 to rise and fall. The bottom of the lifting test plate 4 is equipped with a test strength sensor 5 and a support spring 6. The support spring 6 can provide elastic protection for the crack resistance detection component 7 during resistance testing, avoiding damage to the heating rod due to excessive pressure and affecting the structure of the resistance crack resistance detection. After the crack resistance detection component 7 can be moved downward, it can roll to perform resistance testing on the heating rod, which is quick and convenient. At the same time, the test strength sensor 5 can perform pressure load testing. The height of the crack resistance detection component 7 can be adjusted according to the resistance requirements of the heating rod model, resulting in high resistance measurement accuracy and good adaptability.

[0045] The top of the crack resistance test bench 1 is equipped with a flow guiding and limiting platform 8. The heating rods can roll down sequentially on the flow guiding and limiting platform 8 under the action of gravity. The middle of the flow guiding and limiting platform 8 is equipped with a detection transmission disk 9, which is driven to rotate by a drive motor 11. The detection transmission disk 9 has flow guiding baffle platforms 10 evenly distributed in a ring shape. The heating rods are sequentially guided onto the detection transmission disk 9. A single heating rod can be conducted between two flow guiding baffle platforms 10 and supported by the detection transmission disk 9. During the support process, the crack resistance detection component 7 performs compression resistance detection on the heating rod. The bottom of the crack resistance detection component 7 is a roller structure, which facilitates transmission compression resistance detection, resulting in high detection efficiency and good detection convenience. This allows the device to automatically and quickly measure resistance and crack resistance, with high measurement efficiency. Moreover, the detection intensity can be adjusted according to different models, resulting in high practicality and resistance accuracy.
