Description

Technical Field

[0001] This utility model relates to the field of waterproof fabric testing technology, specifically a waterproof fabric anti-aging performance testing instrument. Background Technology

[0002] Waterproof fabrics are widely used in many fields such as outdoor products, building waterproofing, automotive interiors, and military equipment. Different fields have different requirements for the anti-aging performance of waterproof fabrics. Some require resistance to ultraviolet radiation, some require resistance to humid and hot environments, and others require maintaining stable performance under mechanical stress.

[0003] Currently, most waterproof fabric anti-aging testing equipment on the market uses single-factor simulation, which cannot fully simulate the complex conditions in actual use environments. This leads to significant deviations between test results and actual conditions, failing to accurately reflect the anti-aging performance of waterproof fabric in real-world usage scenarios. Furthermore, waterproof fabric is often subjected to varying degrees of stretching during actual use, and most existing testing equipment ignores this important factor, making it impossible to comprehensively assess the anti-aging performance of waterproof fabric in real-world applications. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a waterproof fabric anti-aging performance tester.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof fabric anti-aging performance tester, comprising a test chamber, a condensation sprayer fixedly installed on the upper surface of the test chamber, a spray head fixedly connected to the spray end of the condensation sprayer, the spray head being disposed inside the condensation sprayer, a set of ultraviolet lamps fixedly installed on the inner top wall of the test chamber, a temperature sensor and a humidity sensor fixedly installed on the inner wall of the test chamber, two electric heating films fixedly installed on the inner bottom wall of the test chamber, and a fixing and pulling mechanism provided inside the test chamber.

[0006] Furthermore, the fixing and pulling mechanism includes a square tube fixedly connected to the inner wall of the detection box, and a motor is fixedly installed on the right side of the square tube.

[0007] Furthermore, a bidirectional lead screw is fixedly installed at the output end of the motor, and the bidirectional lead screw is rotatably connected to the inside of the square tube.

[0008] Furthermore, the outer surface of the bidirectional lead screw is threaded with a first slider and a second slider, and a square rod frame is fixedly connected to the front of the first slider.

[0009] Furthermore, two electric push rods are fixedly installed on the inner top wall of the square rod frame, and clamping plates are fixedly installed at the bottom ends of the two electric push rods. The clamping plates are slidably connected to the inner wall of the square rod frame.

[0010] Furthermore, the drain end of the condensation sprayer is fixedly connected to a drip pipe, a controller is fixedly installed on the upper surface of the test box, and a fan is fixedly installed inside the test box.

[0011] Furthermore, the front right and left sides of the testing box are respectively hinged with maintenance doors. The inside of the right maintenance door is fixedly connected with glass, the front of the right maintenance door is fixedly installed with a display screen, and the front of the right maintenance door is fixedly connected with a handle.

[0012] Furthermore, a drain pipe is fixedly connected to the bottom surface of the testing box, and four support legs are fixedly connected to the bottom surface of the testing box.

[0013] Compared with existing technologies, this waterproof fabric anti-aging performance testing instrument has the following advantages:

[0014] 1. This utility model, by setting up a fixed pulling mechanism, including components such as a square cylinder, a motor, a bidirectional lead screw, a first slider, a second slider, a square rod frame, an electric push rod, and a clamping plate, can realize the pulling or relaxing action of the waterproof cloth sample, simulating the mechanical stress experienced by the waterproof cloth during actual use.

A controller 9 is fixedly installed on the upper surface of the testing box 1. A fan 10 is fixedly installed inside the testing box 1.

[0024] The testing box 1 is equipped with a fixing and pulling mechanism 8, which includes a square tube 801 fixedly connected to the inner wall of the testing box 1. A motor 802 is fixedly installed on the right side of the square tube 801. A bidirectional lead screw 803 is fixedly installed at the output end of the motor 802, and the bidirectional lead screw 803 is rotatably connected to the inside of the square tube 801. A first slider 804 and a second slider 805 are threadedly connected to the outer surface of the bidirectional lead screw 803.

A clamping plate 808 is fixedly installed at the bottom end of the two electric push rods 807, and the clamping plate 808 is slidably connected to the inner wall of the square rod frame 806.

[0025] See Figures 1-4 In some practical applications, two copies of each of the square rod frame 806, electric push rod 807, and clamping plate 808 are provided. Specifically, one set is provided on the front of the first slider 804, and another set is provided on the front of the second slider 805. By placing both ends of the test sample between each square rod frame 806 and clamping plate 808, and then activating the electric push rod 807 to move the clamping plate 808 downward, the sample can be fixed between the square rod frame 806 and clamping plate 808. Then, a certain strength tensile test is performed by activating the motor 802.

[0026] See Figures 1-4 In some practical applications, the testing chamber 1 is made of stainless steel of appropriate thickness to ensure structural stability and corrosion resistance, and is welded and assembled according to the design dimensions. A condensation sprayer 2 is securely installed at a suitable position on the upper surface of the testing chamber 1, allowing the spray head 3 to smoothly extend into the interior of the testing chamber 1, with a reasonable spray direction.

[0027] A set of ultraviolet lamps 4 are evenly distributed and installed on the top wall inside the testing chamber 1, and the power supply line is connected. Temperature sensors 5 and humidity sensors 6 are installed at appropriate positions on the inner wall of the testing chamber 1 to ensure accurate detection of temperature and humidity changes inside the chamber. Two electric heating films 7 are fixedly installed on the bottom wall inside the testing chamber 1, paying attention to the installation position to ensure uniform heating.

[0028] The square tube 801 of the fixed pulling mechanism 8 is firmly fixed to the inner wall of the detection box 1. The motor 802 is installed on the right side of the square tube 801, ensuring that the output shaft of the motor 802 is reliably connected to the bidirectional lead screw 803, and that the bidirectional lead screw 803 and the square tube 801 rotate smoothly. The first slider 804 and the second slider 805 are accurately installed on the outer surface of the bidirectional lead screw 803 and can slide flexibly. The square rod frame 806 is fixed to the front of the first slider 804 and the second slider 805. The electric push rod 807 is installed on the inner top wall of the square rod frame 806. The clamping plate 808 is firmly connected to the electric push rod 807 and can slide smoothly on the inner wall of the square rod frame 806.

[0029] Fan 10 is installed inside the testing chamber 1 to ensure effective air circulation. One end of the drip pipe 11 is tightly connected to the drain end of the condenser sprayer 2, and the other end leads to the drain at the bottom of the testing chamber 1. One end of the drain pipe 12 is fixedly connected to the bottom surface of the testing chamber 1 to drain accumulated water inside the chamber. Four support feet 13 are installed at the four corners of the bottom surface of the testing chamber 1 to ensure the equipment is placed stably.

[0030] The access doors 14 are hinged to the right and left sides of the front of the testing box 1. The glass 15 is fixed inside the right access door 14. The display screen 16 is installed on the front of the right access door 14. The handle 17 is fixed on the front of the right access door 14 for easy opening and closing. The controller 9 is installed on the upper surface of the testing box 1 for easy operation and data monitoring.

[0031] See Figures 1-4 In some practical applications, the equipment power is first turned on, and then preset values ​​such as temperature and humidity, ultraviolet irradiation time and intensity, and tension parameters of the fixed tensioning mechanism 8 are set through the controller 9. The condensation sprayer 2, electric heating film 7, ultraviolet lamp 4, fan 10 and motor 802 of the fixed tensioning mechanism 8 are started, and the operation of each component is checked to see if they are normal.

[0032] Place the waterproof fabric sample to be tested on the fixed tensioning mechanism 8 as required, and activate the electric push rod 807 to fix the sample. Close the inspection door 14, and after confirming that all parameters are set correctly, start the entire testing system through the controller 9 to begin the waterproof fabric anti-aging performance test. During the test, the operator can view the test data in real time through the display screen 16. After the test is completed, open the inspection door 14 to remove the sample for performance evaluation.

[0033] Working principle: Before operating this waterproof fabric anti-aging performance tester, the waterproof fabric sample to be tested must be prepared. Open the inspection door 14, place both ends of the waterproof fabric sample on the corresponding square rod frame 806 in the fixed pulling mechanism 8, start the electric push rod 807, and the electric push rod 807 pushes the clamping plate 808 downward, firmly clamping the waterproof fabric sample between the square rod frame 806 and the clamping plate 808, completing the fixed installation of the sample.

[0034] After preparation, close the inspection door 14 and start the entire testing system via controller 9. First, the condenser sprayer 2 starts working, spraying water mist from the spray head 3 into the testing chamber 1, increasing the humidity inside. Simultaneously, the heating film 7 is energized and heats up, raising the temperature inside the testing chamber 1. Temperature sensor 5 and humidity sensor 6 monitor the temperature and humidity data inside the chamber in real time and feed the data back to controller 9. Controller 9 adjusts the operating status of the condenser sprayer 2 and heating film 7 according to preset temperature and humidity parameters to ensure that the temperature and humidity environment inside the testing chamber 1 meets the set requirements, simulating the humid and hot environment of the waterproof fabric in actual use.

[0035] While the temperature and humidity are being adjusted, ultraviolet lamp 4 illuminates, emitting ultraviolet light to simulate outdoor lighting conditions and irradiate the waterproof fabric sample. Fan 10 operates, promoting air circulation within the testing chamber 1 to ensure uniform distribution of temperature, humidity, and light within the chamber, so that all parts of the waterproof fabric sample are subjected to consistent environmental influences.

[0036] Once the temperature, humidity, and light conditions stabilize, the fixed tensioning mechanism 8 begins operation. Motor 802 starts, and its output drives the bidirectional lead screw 803 to rotate within the square tube 801. Since the outer surface of the bidirectional lead screw 803 is threadedly connected to the first slider 804 and the second slider 805, as the bidirectional lead screw 803 rotates, the first slider 804 and the second slider 805 move in opposite directions along the bidirectional lead screw 803. This causes the square rod frame 806, respectively connected to the front of the first slider 804 and the second slider 805, to move away from or closer to each other, thus achieving the tensioning or relaxing action on the waterproof fabric sample, simulating the mechanical stress experienced by the waterproof fabric during actual use. The controller 9 can set parameters such as the operating speed and number of rotations of motor 802 to precisely control the tension intensity and frequency on the waterproof fabric sample.

[0037] Throughout the testing process, temperature sensor 5 and humidity sensor 6 continuously monitor the temperature and humidity data inside the testing chamber 1. This data is transmitted to controller 9 in real time. Controller 9 dynamically adjusts the working status of condenser sprayer 2 and electric heating film 7 according to the preset temperature and humidity change curve, maintaining a stable temperature and humidity environment and changing according to the set program. Simultaneously, environmental data inside the testing chamber 1 and the working parameters of the fixing and pulling mechanism 8 are transmitted to display screen 16 for real-time display, allowing operators to easily check the testing progress and data status. When the preset testing time is reached or a specific testing task is completed, the entire testing system stops working. Operators open the maintenance door 14, remove the tested waterproof fabric sample, and conduct subsequent performance evaluation and analysis. During this process, excess moisture generated by condenser sprayer 2 is discharged through drip pipe 11, and moisture accumulated at the bottom of testing chamber 1 is discharged through drain pipe 12.
