Description

Technical Field

[0001] The present invention relates to a heat insulation testing device, and particularly to a heat insulation testing device for heat insulation materials. Background Art

[0002] A heat insulation material is a material that can block the transfer of heat flow, also known as a heat insulation material. Traditional heat insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., and new heat insulation materials, such as aerogel felt, vacuum panel, etc. At present, during the production and use of heat insulation materials, it is necessary to conduct heat insulation tests on them in advance to ensure the use effect, and thus a heat insulation testing device is required. However, most of the existing heat insulation testing devices have the drawback of single function, which is not conducive to ensuring the test effect and efficiency, and is inconvenient to use. Therefore, a heat insulation testing device for heat insulation materials with good use effect and high efficiency is needed to improve the test effect and efficiency.

[0003] At present, when the heat insulation testing device is in use, there are still some defects and deficiencies. The specific areas that need to be improved are as follows:

[0004] 1. Most of the current heat insulation testing devices use a single station for testing, and cannot provide multi-station testing, which is not conducive to realizing the synchronization of testing and material loading and unloading. Therefore, to a certain extent, the efficiency of continuous testing of multiple heat insulation materials is reduced;

[0005] 2. Most of the current heat insulation testing devices cannot achieve the effect of driving the heating plate to move left, right, front, and back, which is not conducive to ensuring the comprehensiveness of the heating test. Therefore, to a certain extent, the test accuracy cannot be guaranteed;

[0006] 3. Most of the current heat insulation testing devices do not have the function of simulating the test environment, resulting in limited test environment, which is not conducive to ensuring test diversity;

[0007] 4.

Therefore, to a certain extent, the flexibility of the heat insulation testing device is reduced;

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention is provided with a first motor. When the first motor operates, it drives the driving gear to mesh with the driven gear and rotate, thereby driving the first rotating shaft to rotate. With the help of the connecting rod, the four fixed seats are driven to rotate. Through the position conversion of the four fixed seats, the four test benches are driven to perform position conversion, achieving the effect of performing position conversion on the material samples to be tested in the test bench. During the rotation process, with the rotational cooperation of the pulley in the slide rail, the rotational stability and support are increased, achieving the effect of performing testing and material loading / unloading simultaneously, realizing the purpose of integrating multi-station testing and material loading / unloading, thus solving the problem that most current heat insulation testing devices can only work at a single station, which reduces the testing efficiency to a certain extent, improving the testing efficiency and realizing the continuity of testing at the same time;

[0022] 2. The present invention is provided with a third motor. When the third motor operates, it drives the lead screw to rotate, causing the first threaded plate or the second threaded plate to drive the first slide bar or the second slide bar to move. With the sliding cooperation of the first slide plate and the second slide plate on the surface of the third slide bar, the connecting block drives the electric push rod to move forward and backward or left and right, and then the heating plate moves forward and backward or left and right, achieving the purpose of multi-position heating testing, thus solving the problem that most current heat insulation testing devices cannot flexibly adjust the heating position, resulting in poor heating uniformity, which affects the comprehensiveness of the heating test to a certain extent and reduces the testing accuracy;

[0023] 3. The present invention is provided with a fourth motor. When the fourth motor operates, it drives the half gear to rotate. Through the meshing and separation of the half gear and the toothed rod, with the sliding cooperation of the movable rods in the fixed rods and the elasticity of the springs in the first telescopic assembly and the second telescopic assembly, the purpose of driving the test bench and the ejector rod to vibrate is achieved. During the vibration process, the heat insulation effect of the heat insulation material is tested by heating, thus solving the problem that most current heat insulation testing devices cannot simulate the test environment, which increases the limitations of the heat insulation test to a certain extent, and realizing the purpose of multi-environment testing;

[0024] 4. The present invention is provided with a vacuum pump. When the vacuum pump operates, it performs a vacuum pumping operation on the space formed by the top cover and the test bench, thereby achieving the effect of simulating a vacuum environment and achieving the purpose of heating and testing the material samples to be tested in a vacuum environment, improving the testing diversity;

[0025] 5. When the second motor of the present invention operates, it drives the first transmission wheel to rotate. With the transmission of the transmission chain, the second transmission wheel rotates. Then, the output shaft of the second motor and the second rotating shaft drive the third rotating shaft to rotate, and then drive the clamping plate to rotate, achieving the effect of limiting and releasing the limit of the heat insulation material, thus solving the problem of the material samples to be tested slipping out of the groove during the testing process to a certain extent and ensuring the testing stability.

Then, the electric push rod 27 is controlled by the controller 3 to work, driving the heating plate 25 to move to a suitable distance from the material samples to be tested. Then, the heating plate 25 is controlled by the controller 3 to heat. With the induction of the temperature sensor 23, after reaching the set value, the material samples to be tested are heated and tested. After a period of time, the third motor 31 can be controlled by the controller 3 to work, driving the lead screw 32 to rotate, so that the first threaded plate 33 or the second threaded plate 34 moves. By means of the movement of the first slide bar 36 or the second slide bar 35, the connecting block 26 is driven to move back and forth or left and right, so that the heating plate 25 moves back and forth or left and right to perform multi-position uniform heating test on the material samples to be tested. At the same time, during the test process, the temperature sensor 23 collects temperature data, the thermal imager 22 collects images in real time, and the first thermocouple sensor and the second thermocouple sensor 24 collect the temperatures of the hot and cold surfaces. The data is processed by the microprocessor in the controller 3 and then displayed and recorded in real time through the display screen 4;

When a vibration environment is needed for testing, the controller 3 can be used to control the operation of the fourth motor 412 to drive the rotation of the half gear 411. Through the engagement and separation with the toothed rod 413, with the cooperation of the first telescopic assembly 40 and the second telescopic assembly 44, vibration is generated between the top cover 7 and the test bench 8 to simulate the vibration environment, and the data is collected and recorded.

[0051] After the test of the material sample to be tested in one test bench 8 is completed, the controller 3 can be used to control the operation of the first motor 181 to drive the meshing rotation of the driving gear 182 and the driven gear 183, so that the first rotating shaft 185 drives the connecting rod 21 to rotate, rotate another test bench 8 under the top cover 7, and transmit a signal to the signal receiver 39 installed on the top cover 7 by means of the signal transmitter 12.
