Description

Technical Field

[0001] This invention relates to the field of tensile elasticity testing equipment, specifically to tensile elasticity testing equipment used in the processing of soft composite protective fabrics. Background Technology

[0002] Soft composite protective fabrics are made by laminating, hot-melting, and bonding two or more flexible materials with different functions. They are functional textile materials that combine softness and flexibility with specific protective functions (such as stab resistance, bullet resistance, water resistance, wind resistance, cut resistance, and chemical resistance). Publication number "CN211235262U" discloses a textile tensile testing device, including a base. A motor is fixedly connected to the left side of the bottom of the base cavity, and a drive wheel is fixedly sleeved on the surface of the motor output end. A rotating rod is movably connected to the right side of the bottom of the base cavity, and a driven wheel is fixedly sleeved on the surface of the rotating rod. This utility model solves the problem of low testing efficiency in existing textile tensile testing devices, which can only test one piece of textile fabric at a time, by using a base, support plate, third electric telescopic rod, universal wheel, rotating rod, driven wheel, drive wheel, fixed rod, threaded rod, threaded sleeve, opening, vertical shell, motor, second electric telescopic rod, tension sensor, second clamping plate, connecting plate, movable rod, first electric telescopic rod, first clamping plate and belt in combination. This textile tensile testing device has the advantage of high testing efficiency and is worth promoting. Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: In actual use, fabrics experience multiple complex environments, including high temperatures in summer, low temperatures in winter, humid and rainy conditions, and dry indoor environments. Test data from a single environment cannot accurately reflect the changes in the mechanical properties of the fabric under extreme or variable conditions. The test results deviate significantly from actual usage conditions, limiting their reference value. Some existing testing equipment has obvious functional limitations, mostly only able to conduct tests at room temperature and normal pressure, unable to autonomously simulate various extreme temperature and humidity environments. Although workers can manually pre-treat or process the fabric, such as placing it in a constant temperature and humidity chamber for wet treatment or in a low temperature chamber for freezing treatment, before placing it on the testing equipment for performance testing to adapt it to different environmental conditions, such operations are not only cumbersome and time-consuming, consuming a lot of manpower and time, but also have significant testing drawbacks: First, after manual pre-treatment, the fabric is subjected to secondary influences from the external environment during the transfer to the testing equipment, leading to a decrease in the pre-treatment effect and a reduction in the accuracy of the test data; second, this method cannot achieve simultaneous testing of mechanical properties under different environments, and cannot capture the performance changes of the fabric under stress in real time under different environments.

[0013] This invention also discloses a tensile elasticity testing device and method for processing soft composite protective fabrics, characterized by comprising the following steps: Step 1: Place the fabric sample to be cut on the first conveyor belt, drive the first conveyor belt to move the fabric sample, and then cut the fabric sample by the cutting mechanism. After cutting, multiple fabric samples are moved to the top of the second conveyor belt by the conveying mechanism. Step 2: By activating the second conveyor belt, the fabric sample is moved. Simultaneously, by activating the third electric push rod, its output end moves the first push plate, which in turn moves the conventional box until the contact plate and the second conveyor belt come into contact. At this point, the fabric sample moves to the contact plate and is pushed into the conventional box by the push plate. The conventional box is then reset by the reset mechanism. By driving the rotating shaft to rotate, the small gear and the large gear rotate. The large gear drives the turntable to rotate, thus bringing the humidification box to the position where the conventional box was before. This process continues until multiple samples enter the conventional box, humidification box, cooling box, and heating box respectively. Step 3: The conventional box, humidification box, cooling box and heating box are sealed by the set closing mechanism. Then, the environmental simulation mechanism is used to adjust the temperature and humidity of multiple samples. After standing still for a period of time, the tensile elasticity test of multiple fabric samples is carried out in sequence by the testing mechanism.

[0014] Beneficial effects Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This application can achieve simultaneous testing in multiple environments through an environmental simulation mechanism. The environmental simulation mechanism includes a conventional chamber, a humidification chamber, a cooling chamber, and a heating chamber, which can provide conventional, humid, low-temperature, and high-temperature environments respectively. With the rotation of the turntable, each chamber can work alternately, so that multiple fabric samples are simultaneously placed in different environments. There is no need to set up multiple sets of environmental equipment separately, which greatly improves the testing efficiency. At the same time, the environmental parameters can be precisely adjusted by the corresponding components in each chamber to ensure that the testing environment matches the actual use scenario, thereby improving the accuracy and reference value of the test data. In addition, the fabric does not need to be removed from the chamber during the test, so it can be continuously placed in different environments for tensile elasticity testing, thereby improving the test accuracy. 2. This application uses a reset mechanism to facilitate the smooth entry of fabric samples into the environmental simulation mechanism. The reset mechanism can move the conventional box, humidification box, cooling box and heating box, so that the contact plate is in contact with the conveyor belt, which makes it easy for the pusher plate to push the fabric sample into the box. After the push is completed, the reset mechanism can drive the box to automatically reset, without the need for manual adjustment of the box position, reducing manual intervention and reducing the difficulty of operation. At the same time, it avoids the displacement of the box during the movement, ensuring the smooth progress of subsequent environmental simulation and testing operations and improving the stability of equipment operation. 3. This application can effectively prevent the leakage of hot, cold or humid air inside the environmental simulation mechanism through the closing mechanism. The closing mechanism can drive the closing plate to descend, sealing the conventional box, humidification box, cooling box and heating box, reducing energy loss. At the same time, it can position the fabric sample inside the box to prevent the sample from falling when moving, avoid sample displacement affecting the test results, further ensure the accuracy of test data, simplify the operation process, and improve the practicality and reliability of the equipment.

[0037] This invention also discloses a tensile elasticity testing device and method for processing soft composite protective fabrics, characterized by comprising the following steps: Step 1: Place the fabric sample to be cut on the first conveyor belt 102, drive the first conveyor belt 102 to move the fabric sample, and then cut the fabric sample by the cutting mechanism 1. After cutting, multiple fabric samples are moved to the top of the second conveyor belt 103 by the conveying mechanism 2. Step 2: By activating the second conveyor belt 103, the fabric sample is moved. Simultaneously, by activating the third electric push rod 45, its output end moves the first push plate 46, which in turn moves the conventional box 31 until the contact plate 398 contacts the second conveyor belt 103. At this point, the fabric sample moves onto the contact plate 398 and is pushed into the conventional box 31 by the push plate 397. Subsequently, the conventional box 31 is reset by the reset mechanism 4. By driving the rotating shaft 396 to rotate, the small gear 395 and the large gear 394 rotate. The large gear 394 drives the turntable 104 to rotate, thus bringing the humidification box 32 to the position where the conventional box 31 was. This continues until multiple samples enter the conventional box 31, humidification box 32, cooling box 33, and heating box 34 respectively. Step 3: The conventional box 31, humidification box 32, cooling box 33 and heating box 34 are sealed by the closed mechanism 5. Then, the environmental simulation mechanism 3 is used to adjust the temperature and humidity of multiple samples. After standing still for a period of time, the tensile elasticity test of multiple fabric samples is carried out in sequence by the testing mechanism 6.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Working principle: In actual use, the operator places the fabric sample to be cut on the first conveyor belt 102. The first conveyor belt 102 is driven to move the fabric sample. Then, the first electric push rod 14 is activated, causing the support plate 15 and the cutting blade 16 to descend. The cutting blade 16 cuts the fabric sample. After cutting, the fabric sample reaches the end of the first conveyor belt 102. The second electric push rod 24 is activated, causing the vacuum suction cup 292 to descend until it contacts the fabric sample, forming a sealed cavity. At this point, the air... By opening the supply valve 28 and the vacuum generator 26, the air in the cavity is extracted, and a pressure difference between the inside and outside is generated to achieve a stable adsorption force. By driving the first threaded rod 22 to rotate, the moving plate 23 with the threaded sleeve on the outside of the first threaded rod 22 is moved. The moving plate 23 drives the second electric push rod 24 and the fabric sample to move. When the fabric sample moves above the second conveyor belt 103, the supply valve 28 and the vacuum generator 26 are used to fill the sealed cavity with air to balance the internal and external air pressure and realize the separation of the fabric sample from the vacuum suction cup 292. Then, the second conveyor belt 103 is activated, moving the fabric sample. Simultaneously, the third electric push rod 45 is activated, causing its output end to move the first push plate 46. The first push plate 46 then pushes the conventional box 31 until the contact plate 398 contacts the second conveyor belt 103. At this point, the fabric sample moves onto the contact plate 398 and is pushed into the conventional box 31 by the push plate 397, with both ends of the fabric sample located outside the conventional box 31. Then, the third electric push rod 45 is driven to reset, causing the first push plate 46 to reset as well. During movement, the reset plate 43 at the bottom compresses the reset spring 44, causing it to deform. When the first push plate 46 resets, the reset plate 43 loses the force applied to the reset spring 44, causing the reset spring 44 to release its elastic force and drive the reset plate 43 and the conventional box 31 to reset. Then, by driving the rotating shaft 396 to rotate, the small gear 395 and the large gear 394 are driven to rotate. The large gear 394 drives the turntable 104 to rotate, thereby allowing the humidification box 32 to return to the position where the conventional box 31 was just now, until multiple samples enter the conventional box 31, humidification box 32, cooling box 33 and heating box 34 respectively. By activating the fifth electric push rod 57, its output end drives the disc 58 downward until the disc 58 contacts the ball bearing 55, causing the square plate 51 and vertical rod 52 to descend. The vertical rod 52 then drives the closing plate 54 downward until the conventional box 31, humidification box 32, cooling box 33, and heating box 34 are sealed. Subsequently, by activating the atomizing plate 36, clean water is sprayed out as a mist, thereby increasing the humidity inside the humidification box 32. At the same time, the compressor 37 is activated, drawing in and compressing the low-temperature, low-pressure gaseous refrigerant to output a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser 38. The high-temperature, high-pressure gaseous refrigerant in the condenser 38... In the process of exchanging heat with the outside air, the refrigerant gradually liquefies and becomes a medium-temperature, high-pressure liquid refrigerant, which flows to filter 39. After passing through filter 39, the medium-temperature, high-pressure liquid refrigerant is cleaned and dried by removing moisture and solid impurities. It then enters capillary tube 391. The clean, high-pressure liquid refrigerant passes through the thin capillary tube 391, where the pressure is reduced due to resistance, and becomes a low-temperature, low-pressure gas-liquid mixture. It then enters evaporator 392. In evaporator 392, the low-temperature, low-pressure refrigerant absorbs a large amount of heat and evaporates completely into a gaseous state, causing the temperature around the evaporator to drop and achieving refrigeration. The resulting low-temperature, low-pressure gaseous refrigerant is then drawn into compressor 37 and enters the next cycle until the inside of cooling box 33 reaches a suitable temperature. At the same time, heating tube 393 is turned on to bring the inside of the cooling box to a certain high temperature, while multiple sample fabrics remain still in different environments for a period of time. Finally, by activating the fourth electric push rod 47, its output end drives the second push plate 48 to move, which in turn moves the conventional box 31, humidification box 32, cooling box 33, or heating box 34 located near the testing mechanism 6, bringing them to the middle of the first clamp 62 and the second clamp 67. The operator places the fabric sample into the first clamp 62 and the second clamp 67 through both ends, respectively. By rotating the half-face gear 69, it pushes the movable rod 691 to move. At this time, the movable rod 691 pushes the two clamping plates 693 to move according to the inclined trajectory of the cavity 692 and gradually tighten until the fabric is clamped. Then, by driving the second... The threaded rod 63 rotates, causing the movable plate 66 to move away from the first clamp 62. The data generated by the stretching is reflected on the external display screen through the force sensor 68. The operator can repeatedly move the second clamp 67 to test the elastic recovery rate of the fabric until the fabric breaks. The maximum breaking strength and the elongation at break are recorded. Then the operator tests several fabric samples in different environments and compares them. This allows for simultaneous performance testing and comparative analysis of multiple samples under multiple environmental conditions, effectively improving the efficiency of sample testing and the parallelism and comparability of the data.
