Description

Technical Field

[0001] This utility model relates to the field of clothing testing technology, and in particular to a rapid testing device for the air permeability of fiber clothing. Background Technology

[0002] Fiber clothing is made from natural or chemical fibers as the main raw materials and processed through spinning, weaving, dyeing and finishing processes. Due to its diverse functionality and comfort, this type of clothing is widely used in daily life and special fields. Breathability is a key indicator for measuring the comfort of fiber clothing and directly affects the evaporation of human sweat and heat dissipation. If the breathability is poor, it will cause the wearer to feel stuffy and uncomfortable, and may even cause skin problems. Therefore, it is necessary to test the breathability of fiber clothing. The breathability testing device is a specialized device used to determine the air permeability of fiber clothing materials. By simulating the contact between air and clothing during actual wear, it quantifies the breathability of clothing and provides data support for clothing quality control and product development.

[0003] The existing rapid testing device for the breathability of fiber clothing has the following shortcomings: First, most existing devices use cumbersome bolt or clamp structures to fix the fiber fabric, which involves complicated operation steps and is time-consuming, failing to meet the needs of rapid testing. Second, traditional devices rely on manual application of sealant or the use of a single sealing element in the sealing process, resulting in unstable sealing effects and easy leakage, leading to distorted test data. At the same time, the airflow drive and detection structure of existing devices are separated, resulting in large errors in gas flow measurement and making it difficult to obtain permeability performance data quickly and accurately. Utility Model Content

[0004] This utility model mainly provides a rapid testing device for the air permeability of fiber clothing that is easy to operate, reliably sealed, and provides accurate testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid testing device for the air permeability of fiber clothing, comprising a lower cavity, four hydraulic push rods fixedly connected in a ring array on the outer surface of the lower cavity, an upper cavity fixedly connected to the output ends of the four hydraulic push rods, an air supply pipe fixedly connected to the bottom end of the lower cavity, an exhaust pipe fixedly connected to the top end of the upper cavity, an annular placement groove formed at the top end of the inner surface of the lower cavity, an annular boss fixedly connected to the inner side of the annular placement groove, arc-shaped pressure plates provided on both the left and right sides of the inner surface of the annular placement groove, and rotating operating plates fixedly connected to the outer surface of the arc-shaped pressure plates, with the middle parts of the two rotating operating plates rotatably connected to the left and right ends of the top of the lower cavity, respectively.

[0006] Preferably, rotating baffles are rotatably connected to the top left and right sides of the lower cavity.

[0007] Preferably, a dust filter is fixedly connected to the bottom of the inner surface of the gas pipeline.

[0008] Preferably, a cross bracket is fixedly connected to the middle of the inner surface of the gas pipe, a drive motor is fixedly connected to the middle of the cross bracket, and a guide fan is fixedly connected to the output shaft of the drive motor.

[0009] Preferably, a sealing ring is fixedly connected to the bottom of the upper cavity.

[0010] Preferably, a gas flow meter is fixedly connected to the middle of the exhaust pipe.

[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, by cooperating with the rotating operating plate, the arc-shaped pressure plate, and the rotating baffle, when testing the air permeability of fiber garments, rotating the rotating operating plate causes the arc-shaped pressure plate to rotate out of the annular placement groove. After placing the fiber fabric in the annular placement groove, rotating the arc-shaped pressure plate back in achieves the pressing of the fiber fabric. The rotating baffle is locked at the top of the rotating operating plate, restricting its rotation and ensuring that the arc-shaped pressure plate firmly presses the fabric. Compared with the traditional cumbersome bolt fixing or clamp structure, this structure does not require complicated disassembly and assembly steps, greatly shortens the fabric fixing time, achieves rapid fixing of fiber fabric, and significantly improves testing efficiency.

[0012] 2. In this utility model, when testing the limited-position garment, the hydraulic push rod drives the upper cavity to slide downward and press against the top of the lower cavity. The sealing ring at the bottom of the upper cavity is aligned with the annular protrusion in the lower cavity, forming a double sealing structure to ensure the airtightness of the testing chamber. At the same time, the drive motor in the air supply pipe drives the guide fan to rotate, allowing air to enter the lower cavity from the air supply pipe, pass through the fabric into the upper cavity, and then be discharged from the exhaust pipe. The gas flow meter in the middle of the exhaust pipe can directly detect the gas flow rate through the fiber fabric. This integrated design avoids the air leakage problem caused by poor sealing in traditional devices, as well as the measurement error caused by the separation of airflow drive and detection, ensuring the accuracy and reliability of the test data and realizing rapid and accurate testing of the air permeability of fiber garments.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a rapid testing device for the air permeability of fiber clothing, including a lower cavity 1. Four hydraulic push rods 2 are fixedly connected in a ring array on the outer surface of the lower cavity 1. An upper cavity 3 is fixedly connected to the output end of the four hydraulic push rods 2. An air supply pipe 4 is fixedly connected to the bottom end of the lower cavity 1. An exhaust pipe 5 is fixedly connected to the top end of the upper cavity 3. An annular placement groove 11 is opened at the top end of the inner surface of the lower cavity 1. An annular boss 12 is fixedly connected to the inner side of the annular placement groove 11. Arc-shaped pressure plates 13 are provided on both the left and right sides of the inner surface of the annular placement groove 11. Rotating operating plates 14 are fixedly connected to the outer surface of the arc-shaped pressure plates 13. The middle parts of the two rotating operating plates 14 are rotatably connected to the left and right ends of the top of the lower cavity 1, respectively.

[0018] like Figure 2 As shown, rotating baffles 15 are rotatably connected to the top left and right sides of the lower cavity 1. Here, the rotating baffles 15 are set so that after the arc-shaped pressure plate 13 presses the fiber fabric, the rotating baffles 15 can be rotated to lock it on the top of the rotating operation plate 14, restricting the rotation of the rotating operation plate 14, thereby ensuring that the arc-shaped pressure plate 13 always firmly presses the fiber fabric, avoiding displacement or loosening of the fabric during the testing process, and ensuring the stability of the testing process and the accuracy of the testing results.

[0019] like Figure 3As shown, a dust filter 41 is fixedly connected to the bottom of the inner surface of the air supply pipe 4. Here, the dust filter 41 can effectively intercept dust, fiber debris and other impurities carried in the outside air, prevent these impurities from entering the inside of the detection device, avoid impurities clogging the air supply pipe 4 or adhering to the surface of the fiber fabric, affecting the normal air circulation and the accuracy of the air permeability test, and at the same time reduce the wear of impurities on other components inside the device, and extend the service life of the device.

[0020] like Figure 3 As shown, a cross bracket 42 is fixedly connected to the middle of the inner surface of the air supply pipe 4, and a drive motor 43 is fixedly connected to the middle of the cross bracket 42. A guide fan 44 is fixedly connected to the output shaft of the drive motor 43. Here, after the drive motor 43 starts, it drives the guide fan 44 to rotate at high speed, generating a stable airflow to provide a power source for the detection process. The airflow generated by the rotation of the guide fan 44 is evenly transported to the lower cavity 1 through the air supply pipe 4, so that the airflow can pass through the fiber fabric stably and evenly, ensuring the consistency of airflow conditions during the detection process, thereby improving the reliability and repeatability of the detection data.

[0021] like Figure 4 As shown, a sealing ring 31 is fixedly connected to the bottom of the upper cavity 3. Here, when the hydraulic push rod 2 drives the upper cavity 3 to slide downward and press against the top of the lower cavity 1, the sealing ring 31 is tightly fitted with the annular boss 12 in the lower cavity to form a double sealing structure. This sealing method can effectively prevent gas leakage during the test and ensure that the air entering the lower cavity 1 can only enter the upper cavity 3 through the fiber fabric, thereby ensuring the accuracy of the air permeability test data and avoiding deviations in the test results due to air leakage.

[0022] like Figure 4 As shown, a gas flow meter 51 is fixedly connected to the middle of the exhaust pipe 5. Here, the gas flow meter 51 can measure the gas flow rate discharged from the exhaust pipe 5 after passing through the fiber fabric in real time and accurately. By accurately measuring the gas flow rate, the air permeability performance of the fiber garment can be directly quantified, providing reliable data support for garment quality assessment and research and development. At the same time, the setting of the gas flow meter 51 makes the testing process more intuitive and convenient, allowing testing personnel to quickly obtain test results and improve testing efficiency.

[0023] The method of use and working principle of this device: First, rotate the rotating operation plate 14 to drive the arc-shaped pressure plate 13 out of the annular placement groove 11 and place the fiber fabric to be tested flat in the annular placement groove 11. Then, rotate the rotating operation plate 14 in the opposite direction to make the arc-shaped pressure plate 13 rotate back and press the fiber fabric. Next, rotate the rotating baffle 15 to make it lock in the top of the rotating operation plate 14 to complete the fixing of the fiber fabric. Subsequently, the hydraulic push rod 2 is activated, and the four hydraulic push rods 2 work synchronously, driving the upper cavity 3 to slide downward until the sealing ring 31 at the bottom of the upper cavity 3 is tightly fitted with the annular boss 12 in the lower cavity, thus achieving the sealing of the detection cavity; Next, the drive motor 43 is started, and the drive motor 43 drives the guide fan 44 to rotate at high speed. Under the action of the guide fan 44, the outside air enters the air supply pipe 4 after being filtered by the dust filter 41 at the bottom of the air supply pipe 4. Then, it is transported to the lower cavity 1 through the air supply pipe 4. The air entering the lower cavity 1 passes through the fiber fabric under pressure and enters the upper cavity 3, and is finally discharged from the exhaust pipe 5. As air passes through the fiber fabric and is discharged from the exhaust pipe 5, the gas flow meter 51 in the middle of the exhaust pipe 5 measures the gas flow in real time. The tester can directly read the data displayed by the gas flow meter 51, which is the quantitative indicator of the air permeability of the fiber garment, thereby realizing the rapid test of the air permeability of the fiber garment. After the test is completed, first turn off the drive motor 43, then start the hydraulic push rod 2 to make the upper cavity 3 rise and reset, rotate the rotating baffle 15 and rotate the rotating operation plate 14, take out the tested fiber fabric, and prepare for the next test.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
