Description

Technical Field

[0001] This utility model relates to the field of aerogel insulation felt production technology, specifically a tensile strength testing mechanism for aerogel insulation felt production. Background Technology

[0002] Aerogel insulation felt is a high-performance insulation material. Its core component is a nanoporous aerogel, which has extremely low thermal conductivity, effectively preventing heat conduction and providing insulation far superior to traditional insulation materials. It also boasts excellent chemical stability, resisting acid and alkali corrosion and maintaining its insulation performance even in harsh chemical environments. Furthermore, it exhibits outstanding fire resistance, not burning or producing smoke when exposed to open flames, providing reliable safety for the environment. Therefore, it is widely used in many fields such as industrial pipeline insulation, building exterior wall insulation, and automotive engine insulation. During the production process, tensile strength testing is necessary to ensure product quality.

[0003] In the prior art, Chinese Patent No. CN218180497U discloses a fabric tensile strength testing machine, including a base, a tensioning mechanism at the top of the base, a pressure gauge on the tensioning mechanism, a first clamping mechanism at the bottom of the pressure gauge, and a second clamping mechanism at the middle of the top of the base. The first clamping mechanism includes a U-shaped seat, a fixed seat, and a movable seat. The fixed seat is connected to one side of the inner wall of the U-shaped seat, and a second screw is rotatably connected to one side wall of the movable seat. The second screw is threadedly connected to the side wall of the U-shaped seat away from the fixed seat. Clamping teeth are installed on the opposite side walls of the fixed seat and the movable seat. The clamping teeth on the fixed seat and the clamping teeth on the movable seat are adapted to quickly clamp the ends of the raw fabric sample, preventing it from falling off during the tensile test and improving the testing efficiency.

[0004] Based on the above information, it is clear that existing technologies use a simple stretching method for tensile testing. However, for materials like aerogel insulation felt, which have a special texture and loose structure, it is difficult to accurately control the stretching speed and force, resulting in large errors in the test results. Moreover, only one sample can be tested at a time, making it impossible to test multiple samples simultaneously, which leads to low testing efficiency. Therefore, we propose a tensile testing mechanism for aerogel insulation felt production. Utility Model Content

For aerogel insulation felt, a material with special texture and loose structure, it is difficult to accurately control the stretching speed and force, resulting in large errors in the test results. Moreover, when testing samples, only one sample can be tested at a time, which cannot achieve simultaneous testing of multiple samples and results in low testing efficiency.

[0006] To achieve the above object, the utility model provides the following technical solutions: A tensile property detection mechanism for the production of aerogel thermal insulation felts, including a device main body, wherein a detection component for detecting the tensile property of the aerogel thermal insulation felt is provided on the outer wall of the device main body, and it is characterized in that: The detection component includes a winding roller rotatably installed on the outer wall of the device main body, and a driving motor is fixedly installed at the end of the winding roller.

A bidirectional threaded rod rotatably connected to the winding roller is threadedly installed on the outer wall of the clamping plate. A guide rod slidably connected to the clamping plate is fixedly installed on the inner wall of the placement groove. A tensile force sensor and an infrared sensor are provided on the outer wall of the device main body. A control panel is fixedly installed on the outer wall of the device main body, and a display screen is provided on the outer wall of the control panel. A limiting component for fixing the aerogel thermal insulation felt sample is provided on the outer wall of the tensile force sensor.

[0007] Further, the cross-section of the placement groove is rectangular, and the placement groove is a through groove penetrating the winding roller, and the length of the placement groove is less than the length of the winding roller.

[0008] Further, the clamping plate is designed corresponding to the placement groove, and two groups of clamping plates are symmetrically arranged on the outer wall of the bidirectional threaded rod, and the outer wall of the clamping plate is in contact with the outer wall of the aerogel thermal insulation felt sample.

[0009] Further, two groups of guide rods are symmetrically arranged in the placement groove, and the length of the guide rod is correspondingly set to the width of the placement groove, and the guide rod penetrates the outer walls of the two groups of clamping plates.

[0010] Further, the tensile force sensor is arranged on the outer wall of the device main body corresponding to the winding roller, and the tensile force sensors are arranged at equal intervals. The infrared sensor is located between the tensile force sensor and the winding roller, and the infrared sensor is designed corresponding to the aerogel thermal insulation felt sample. Both the tensile force sensor and the infrared sensor are electrically connected to the control panel.

[0011] Further, the limiting component includes a fixed seat fixedly installed on the outer wall of the tensile force sensor, a sliding rod is fixedly installed on the outer wall of the fixed seat, and a limiting plate is slidably installed on the outer wall of the sliding rod. A limiting bolt with an outer wall threadedly connected to the fixed seat is rotatably installed on the outer wall of the limiting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This tensile strength testing mechanism for aerogel insulation felt production, equipped with testing components, drives a motor to rotate the winding roller, precisely controlling the winding speed and thus stabilizing the tensile speed and force of the aerogel insulation felt sample. The clamps in the placement groove can be adjusted in spacing via bidirectional threaded rods to accommodate samples of different specifications. The clamps slide stably under the constraint of guide rods, ensuring the fixation effect on the sample. Multiple sets of tensile sensors can accurately detect the tensile force on the sample at different positions in real time, and infrared sensors can monitor subtle displacement changes during the sample stretching process in real time. These data are synchronously transmitted to the control panel and displayed on the screen, greatly improving the accuracy of the test results. It can also test multiple samples simultaneously, significantly improving the testing efficiency.

[0016] 2. By setting a limiting component, the slide bar on the fixed seat provides a stable sliding guide for the limiting plate. Rotating the limiting bolt can easily adjust the position of the limiting plate to adapt to aerogel insulation felt samples of different specifications. The buffer pad is made of rubber to avoid the limiting plate directly contacting the sample and causing damage. The trapezoidal anti-slip block on its outer wall can effectively increase the friction force to ensure that the sample is stably limited during the test, preventing slippage or falling off, and ensuring the smooth progress of the test and the reliability of the data.

Detailed Implementation

[0024] 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.

[0025] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: a tensile strength testing mechanism for aerogel insulation felt production, comprising a device body 1, a testing component for testing the tensile strength of aerogel insulation felt on the outer wall of the device body 1, the testing component including a take-up roller 8 rotatably mounted on the outer wall of the device body 1, a drive motor 7 fixedly mounted at the end of the take-up roller 8, a placement groove 801 opened on the outer wall of the take-up roller 8, a clamping plate 802 slidably mounted on the inner wall of the placement groove 801, a bidirectional threaded rod 803 rotatably connected to the take-up roller 8 threadedly mounted on the outer wall of the clamping plate 802, a guide rod 804 slidably connected to the clamping plate 802 fixedly mounted on the inner wall of the placement groove 801, a tensile sensor 3 and an infrared sensor 4 provided on the outer wall of the device body 1, a control panel 2 fixedly mounted on the outer wall of the device body 1, and a display screen 201 provided on the outer wall of the control panel 2, the placement groove 801 having a cross-section of [missing information]. The device is rectangular, with the placement groove 801 being a through groove that passes through the take-up roller 8, and the length of the placement groove 801 being less than the length of the take-up roller 8. The clamping plate 802 is designed to correspond to the placement groove 801, and two sets of clamping plates 802 are symmetrically arranged on the outer wall of the bidirectional threaded rod 803, and the outer wall of the clamping plate 802 is in contact with the outer wall of the aerogel insulation felt sample. Two sets of guide rods 804 are symmetrically arranged in the placement groove 801, and the length of the guide rods 804 is set to correspond to the width of the placement groove 801, and the guide rods 804 pass through the outer walls of the two sets of clamping plates 802. The tension sensor 3 is set on the outer wall of the device body 1 on the side corresponding to the take-up roller 8, and the tension sensor 3 is set at equal intervals. The infrared sensor 4 is located between the tension sensor 3 and the take-up roller 8, and the infrared sensor 4 is designed to correspond to the aerogel insulation felt sample. Both the tension sensor 3 and the infrared sensor 4 are electrically connected to the control panel 2.

[0026] During the testing process of the tensile strength testing mechanism for aerogel insulation felt production, the drive motor 7 serves as the power source. After being turned on, its output shaft drives the winding roller 8 to rotate stably. The operator can preset the speed of the drive motor 7 through the control panel 2 according to the characteristics of the aerogel insulation felt sample and the testing standards, thereby precisely controlling the winding speed of the winding roller 8. As the winding roller 8 rotates, the aerogel insulation felt sample placed in the placement groove 801 and fixed by the clamping plate 802 is gradually stretched. The operator can rotate the bidirectional threaded rod 803 according to the specifications of the aerogel insulation felt sample. The rotation of the bidirectional threaded rod 803 causes the clamping plate 802, which is threaded to it, to slide smoothly along the inner wall of the placement groove 801 under the restriction of the guide rod 804. The device moves to firmly clamp samples of different specifications. During this process, multiple sets of tension sensors 3, evenly distributed on the outer wall of the main body 1 and the winding roller 8 on the opposite side, constantly monitor the tension on the samples at different positions and transmit the real-time data to the control panel 2. At the same time, infrared sensors 4, located between the tension sensors 3 and the winding roller 8 and corresponding to the aerogel insulation felt sample, use infrared monitoring technology to capture the subtle displacement changes of the sample during the stretching process and transmit the data to the control panel 2 as well. The control panel 2 summarizes and analyzes this data and presents the results on the display screen 201, providing operators with accurate and comprehensive test data and enabling accurate evaluation of the tensile performance of the aerogel insulation felt.

[0027] Example 2: Based on Example 1, a limiting component is also disclosed, the specific structure of which is as follows: The outer wall of the tension sensor 3 is provided with a limiting component for fixing the aerogel insulation felt sample. The limiting component includes a fixing seat 5 fixedly installed on the outer wall of the tension sensor 3, and a sliding rod 503 is fixedly installed on the outer wall of the fixing seat 5. A limiting plate 501 is slidably installed on the outer wall of the sliding rod 503. A limiting bolt 502 is rotatably installed on the outer wall of the limiting plate 501 and threadedly connected to the fixing seat 5. A buffer pad 6 is fixedly installed on the wall, and an anti-slip block 601 is provided on the outer wall of the buffer pad 6. The fixed seat 5 is correspondingly set with the tension sensor 3, and the fixed seat 5 has a "U" shaped cross section. Two sets of slide rods 503 are symmetrically set on the outer wall of the fixed seat 5, and the length of the slide rods 503 is corresponding to that of the fixed seat 5. The buffer pad 6 is made of rubber and is provided on the outer walls of both the fixed seat 5 and the clamping plate 802. The anti-slip block 601 has a trapezoidal cross section and is evenly spaced on the outer wall of the buffer pad 6.

[0028] When testing aerogel insulation felt samples, the fixing seat 5 is securely installed on the outer wall of the tension sensor 3, providing a support base for the entire limiting assembly. For aerogel insulation felt samples of different thicknesses, the operator can adjust the position of the limiting plate 501 by rotating the limiting bolt 502. The limiting bolt 502 is threadedly connected to the fixing seat 5. When rotating, the limiting plate 501 slides smoothly up and down under the guidance of the slide rod 503 on the fixing seat 5 until it reaches the position that matches the sample thickness. At this time, the rubber buffer pad 6 fixed on the outer wall of the limiting plate 501 comes into contact with the sample. Due to the good flexibility and elasticity of the rubber material, it can effectively prevent the limiting plate 501 from causing hard damage to the surface of the aerogel insulation felt sample. The anti-slip block 601 with a trapezoidal design on the outer wall of the buffer pad 6 further plays a role. Its special shape increases the contact area and friction between the buffer pad 6 and the sample, so that the sample is firmly limited in a fixed position throughout the testing process. Even when the testing assembly is subjected to rapid and high-intensity tensile operations, it can prevent the sample from sliding or falling off, ensuring the smooth progress of the testing work and guaranteeing the accuracy and reliability of the test data.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
