Description

[0001] This application is a divisional application of application filed on November 3, 2025, with application number 2025115906036 and invention title "A textile air permeability testing device based on new material testing". Technical Field

[0002] This invention belongs to the field of fabric testing technology, and specifically relates to a device for testing the air permeability of textile materials. Background Technology

[0003] Textile breathability refers to the ability of textiles to allow air or water vapor to pass through them, and is one of the important indicators for measuring the comfort and suitability of textiles.

[0004] A search revealed that Chinese Patent Publication No. CN116559054B, published on November 17, 2023, discloses a textile air permeability testing device. The device includes a worktable with a lever arm on its bearing surface and a first linear actuator on the lever arm. A pressure frame for pressing the textile is mounted on the output end of the first linear actuator. Contact elements are distributed at the four corners of the pressure frame. A segmented expansion mechanism is also provided at the output end of the first linear actuator. A frame is slidably mounted on the pressure frame, distributed on both sides of the X-axis of the pressure frame. Sliding rods are fixedly mounted on the contact elements. This invention drives the four contact elements to move through the segmented expansion mechanism. First, the contact elements on both sides of the pressure frame along the X-axis of the frame move away from each other. Then, the frame elements on both sides of the pressure frame along the axis of the first limiting rod move away from each other, ultimately resulting in a completely flattened state before the pressure frame presses the textile.

[0005] However, the testing equipment still has the following defects: Textiles are elastic, and their pore size changes under different tensions. However, existing testing equipment can only test textiles under a single tension, requiring multiple tests for different tensions, which reduces the efficiency of the testing process.

[0009] Furthermore, several sets of the jet nozzles are connected to the output end of the blower; two sets of sliding grooves are symmetrically opened on the inner walls of both sides of the movable groove; the top two ends of each set of isolation plates are respectively damped and slidably connected in a corresponding set of sliding grooves; several sets of return springs are provided in each set of sliding grooves.

[0010] Furthermore, each set of return springs has its two ends connected to a corresponding set of isolation plates or the inner wall of the movable groove; the bottom of each set of isolation plates has several sets of engagement grooves arranged in a diamond shape; and each set of engagement teeth moves through a corresponding set of engagement grooves.

[0011] Furthermore, the sealing assembly includes a mounting frame plate; several sets of mounting slots are symmetrically and equally spaced on the inner walls of both sides of the mounting frame plate; a set of motors is provided on the bottom inner wall of each set of mounting slots; and a set of cleaning modules is drivenly connected to the output end of each set of motors.

[0012] Furthermore, the cleaning module includes a rotating shaft; a fixed sleeve and a movable sleeve are provided on the outer wall of the rotating shaft; a set of mounting sleeves are provided on the outer wall of both the fixed sleeve and the movable sleeve; a number of grooves are equally spaced on the outer wall of each set of movable sleeves; a set of rubber magnets are provided in each set of grooves; each set of rubber magnets is magnetically attracted to the corresponding set of grooves.

[0013] Furthermore, each set of rubber magnets has an adsorption pad on the side wall away from the rotating shaft; the rotating shaft has an adjustment cavity; a slider is slidably connected in the adjustment cavity; the slider is drivenly connected to the movable sleeve; a second lead screw is provided in the adjustment cavity; the second lead screw is threadedly connected to the slider.

[0014] Furthermore, the conveying mechanism includes a connecting seat; the connecting seat has a conveying groove; a first conveying roller and a second conveying roller are provided in the conveying groove; a number of humidity sensors are provided on the outer wall of the first conveying roller; a number of conveying cavities are arranged in a ring array inside the second conveying roller; a number of conveying holes are evenly spaced on the inner wall of each conveying cavity on the side away from the central axis of the second conveying roller.

[0015] Furthermore, a connecting ring is provided on one inner wall of the conveying channel; the connecting ring is rotatably connected to the second conveying roller and is movably connected to any set of conveying chambers; a liquid storage chamber is provided in the connecting seat; an atomizing pump is provided in the connecting seat; the input end of the atomizing pump is connected to the liquid storage chamber, and the output end is connected to the connecting ring.

[0016] The beneficial effects of this invention are: 1. By controlling the synchronous movement of two sets of translation plates, the corresponding tension adjustment plates move horizontally. Since each set of tension adjustment plates has several sets of interlocking teeth arranged in a diamond shape on its top, when the tension adjustment plates reciprocate, they can smooth out the wrinkles on the textile. Furthermore, the interlocking teeth on the top of the tension adjustment plates can clamp and fix the textile. By controlling the horizontal position of the translation plates, different areas on the textile are subjected to different tensions. This allows the testing device to simultaneously test the air permeability of the textile under different tensions, improving the testing efficiency of the device while reducing the interference of textile wrinkles on the test results.

[0017] 2. Several sets of biting teeth enter a corresponding set of biting grooves, thereby forming a multi-segment biting fixation of the textile, avoiding wrinkles when adjusting the textile to form different tension areas. Furthermore, since several sets of isolation plates are damped and slidably connected in two sets of sliding grooves, several sets of translation plates can drive the corresponding isolation plates to move horizontally during horizontal movement. This ensures that different tension detection areas on the textile are in independent spaces, avoiding mutual interference of airflow and improving the detection accuracy of the detection device.

[0018] 3. By controlling the electric push rod to lower the adaptive detection mechanism above the textile, several sets of motors are then controlled to rotate several sets of cleaning modules from their respective mounting slots to a horizontal position. The movable sleeve is then moved away from the motor to expand the cleaning area. The motor then drives the rotating shaft to rotate, causing several sets of rubber magnets to be thrown out under centrifugal force. This allows the adsorption pads to adsorb impurities attached to the top of the textile. Combined with the reciprocating motion of several sets of biting teeth to clean impurities on the bottom of the textile, this reduces the interference of impurities on the textile with the detection results and improves the effectiveness of the detection device.

[0019] 4. The textile can be fed through two sets of conveying mechanisms. At the input end, the textile forms two sets of bending areas through the first conveying roller and the second conveying roller. The bending areas can adhere to part of the outer wall of the first conveying roller and the second conveying roller. The water source in the storage chamber is atomized by the atomizing pump and sprayed out from several sets of conveying holes through the corresponding conveying chamber, thereby changing the humidity of the textile. Subsequently, the humidity sensor on the first conveying roller monitors the humidity, so that the detection device can adjust the humidity of the textile in real time, thereby realizing the detection of the air permeability performance of the textile under different humidity conditions.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a device for testing the air permeability of textile materials, including a testing platform 1. For example, as shown... Figure 1 , Figure 2 and Figure 3As shown, a mounting bracket 2 is provided at one edge of the top of the detection platform 1; an electric push rod 3 is provided at the top of the mounting bracket 2; an adaptive detection mechanism 4 is connected to the output end of the electric push rod 3; several sets of tension adjustment plates 7 are movably inserted through the top of the detection platform 1 at equal intervals; several sets of meshing teeth 12 are distributed in a diamond shape at the top of each set of tension adjustment plates 7; two sets of adjustment slots 5 are symmetrically opened on the top of the detection platform 1; several sets of translation plates 9 are provided in each set of adjustment slots 5; a set of electric slides 6 is provided at the end of the top of each set of translation plates 9 away from the edge of the detection platform 1; both ends of each set of tension adjustment plates 7 are respectively connected to the output end of the corresponding set of electric slides 6; several sets of first lead screws 10 are arranged in parallel in each set of adjustment slots 5; each set of first lead screws 10 is threadedly connected to the corresponding set of translation plates 9; several sets of wind pressure sensors 11 are arranged in a rectangular array on the top of the detection platform 1; two sets of conveying mechanisms 8 are symmetrically arranged at the two edges of the top of the detection platform 1.

[0026] When testing the air permeability of textiles, the textile is first conveyed through one set of conveying mechanisms 8 and connected to another set of conveying mechanisms 8. Then, several sets of electric slides 6 are controlled to move several sets of tension adjusting plates 7 upwards to contact the bottom of the textile. By controlling the synchronous rotation of the corresponding two sets of first lead screws 10, the corresponding two sets of translation plates 9 can move synchronously. The corresponding two sets of electric slides 6 drive the tension adjusting plates 7 to move horizontally. Since the top of each set of tension adjusting plates 7 is provided with several sets of biting teeth 12 in a diamond shape, when the several sets of tension adjusting plates 7 reciprocate, the wrinkles on the textile can be smoothed out, and the several sets of biting teeth 12 on the top of the several sets of tension adjusting plates 7 can bite and fix the textile. By controlling the horizontal position of the several sets of translation plates 9, different areas on the textile are made to form different tensions, so that the testing device can simultaneously test the air permeability of the textile under different tensions. This improves the testing efficiency of the testing device and reduces the interference of textile wrinkles on the test results.

[0027] For example, such as Figure 4 and Figure 5As shown, the adaptive detection mechanism 4 includes a mounting plate 401; a sealing assembly 402 is provided at the bottom of the mounting plate 401; a blower 403 is provided at the top of the mounting plate 401; several sets of isolation plates 404 are provided at the bottom of the mounting plate 401; a movable groove 405 is opened at the bottom of the mounting plate 401; several sets of air jets 406 are arranged in a rectangular array on the top inner wall of the movable groove 405; the several sets of air jets 406 are connected to the output end of the blower 403; the two sides of the movable groove 405... Two sets of sliding grooves 407 are symmetrically provided on the inner wall; the top two ends of each set of isolation plates 404 are respectively damped and slidably connected in the corresponding set of sliding grooves 407; each set of sliding grooves 407 is provided with several sets of return springs 408; the two ends of each set of return springs 408 are respectively connected to the inner wall of the corresponding set of isolation plates 404 or movable grooves 405; the bottom of each set of isolation plates 404 is provided with several sets of engagement grooves 409 in a diamond shape; each set of engagement teeth 12 is movably inserted through the corresponding set of engagement grooves 409.

[0028] During the air permeability test of textiles, several sets of interlocking teeth 12 enter a corresponding set of interlocking grooves 409, thereby forming a multi-segment interlocking fixation of the textile, avoiding wrinkles when adjusting the textile to form different tension areas. Since several sets of isolation plates 404 are damped slidingly connected in two sets of sliding grooves 407, several sets of translation plates 9 can drive the corresponding isolation plates 404 to move horizontally during horizontal movement, so that different tension testing areas on the textile are in independent spaces, avoiding mutual interference of airflow and improving the detection accuracy of the testing device. Subsequently, the blower 403 is controlled to spray airflow through several sets of jet nozzles 406. After the airflow passes through different tension areas of the textile, it is detected by the wind pressure sensors 11 set in a rectangular array.

[0029] For example, such as Figure 6 As shown, the sealing assembly 402 includes a mounting frame plate 4021; several sets of mounting grooves 4022 are symmetrically and equally spaced on the inner walls of both sides of the mounting frame plate 4021; a set of motors 4023 is provided on the bottom inner wall of each set of mounting grooves 4022; a set of cleaning modules 4024 is drivenly connected to the output end of each set of motors 4023.

[0030] For example, such as Figure 7 and Figure 8As shown, the cleaning module 4024 includes a rotating shaft 40241; a fixed sleeve 40242 and a movable sleeve 40243 are provided on the outer wall of the rotating shaft 40241; a set of mounting sleeves 40244 are provided on the outer wall of both the fixed sleeve 40242 and the movable sleeve 40243; several sets of grooves are equally spaced on the outer wall of each set of movable sleeves 40243; a set of rubber magnets 40245 are provided in each set of grooves; each set of rubber magnets 40245 is magnetically attracted to the corresponding... Each set of rubber magnets 40245 is provided with an adsorption pad 40246 on the side wall away from the rotating shaft 40241; the rotating shaft 40241 is provided with an adjustment cavity 40247; a slider 40248 is slidably connected in the adjustment cavity 40247; the slider 40248 is connected to the movable sleeve 40243 in a transmission manner; a second lead screw 40249 is provided in the adjustment cavity 40247; the second lead screw 40249 is threadedly connected to the slider 40248.

[0031] Before conducting the air permeability test on textiles, the electric push rod 3 is controlled to lower the adaptive detection mechanism 4 above the textile. Then, several sets of motors 4023 are controlled to rotate several sets of cleaning modules 4024 from their respective mounting slots 4022 to a horizontal position. Subsequently, several sets of second lead screws 40249 are controlled to rotate. With the threaded connection between the second lead screws 40249 and the slider 40248, the slider 40248 drives the movable sleeve 40243 to move away from the motor 4023, thereby expanding the cleaning area. Then, the motor 4023 is controlled to rotate the rotating shaft 40241, causing several sets of rubber magnets 40245 to be thrown out under the action of centrifugal force. This allows the adsorption pads 40246 to adsorb impurities attached to the top of the textile. Combined with the reciprocating motion of several sets of biting teeth 12 to clean impurities on the bottom of the textile, the interference of impurities attached to the textile on the test results is reduced, and the effectiveness of the testing device is improved.

[0032] For example, such as Figure 9 and Figure 10As shown, the conveying mechanism 8 includes a connecting seat 801; a conveying groove 802 is provided on the connecting seat 801; a first conveying roller 803 and a second conveying roller 804 are provided in the conveying groove 802; several sets of humidity sensors are provided on the outer wall of the first conveying roller 803; several sets of conveying cavities 805 are arranged in a circular array in the second conveying roller 804; several sets of conveying holes 806 are evenly spaced on the inner wall of the side of each set of conveying cavities 805 away from the central axis of the second conveying roller 804; a connecting ring 807 is provided on the inner wall of one side of the conveying groove 802; the connecting ring 807 is rotatably connected to the second conveying roller 804 and is movably connected to any set of conveying cavities 805; a liquid storage chamber 808 is provided in the connecting seat 801; an atomizing pump is provided in the connecting seat 801; the input end of the atomizing pump is connected to the liquid storage chamber 808, and the output end is connected to the connecting ring 807.

[0033] When testing the air permeability of textiles, the textiles are fed through two sets of conveying mechanisms 8. At the input end, the textiles form two sets of bending areas through the first conveying roller 803 and the second conveying roller 804. The bending areas can adhere to part of the outer wall of the first conveying roller 803 and the second conveying roller 804. The water source in the liquid storage chamber 808 is atomized by the atomizing pump and sprayed out from several sets of conveying holes 806 through the corresponding conveying chamber 805, changing the humidity of the textiles. Subsequently, the humidity sensor on the first conveying roller 803 monitors the humidity, so that the testing device can adjust the humidity of the textiles in real time, thereby realizing the air permeability testing of textiles under different humidity levels.

[0034] Working principle: When testing the air permeability of textiles, the textiles are first fed through two sets of conveying mechanisms 8. At the input end, the textiles form two sets of bending areas via the first conveying roller 803 and the second conveying roller 804. These bending areas can adhere to a portion of the outer wall of the first and second conveying rollers 803 and 804. Water from the storage chamber 808 is atomized by an atomizing pump and sprayed through corresponding conveying chambers 805 and several sets of conveying holes 806, thus changing the humidity of the textiles. The humidity is then monitored by a humidity sensor on the first conveying roller 803. Then, several sets of electric slides 6 are controlled to drive several sets of tension adjusting plates 7 to move upward and abut against the bottom of the textile. By controlling the synchronous rotation of the corresponding two sets of first lead screws 10, the corresponding two sets of translation plates 9 can move synchronously, and the corresponding two sets of electric slides 6 drive the tension adjusting plates 7 to move horizontally. Since the top of each set of tension adjusting plates 7 is provided with several sets of interlocking teeth 12 in a diamond shape, when the several sets of tension adjusting plates 7 reciprocate, they can smooth out the wrinkles on the textile and remove impurities from the bottom of the textile. Then, the adaptive detection machine is controlled. The structure 4 descends above the textile, then controls several sets of motors 4023 to drive several sets of cleaning modules 4024 to rotate from their respective mounting slots 4022 to a horizontal position. Subsequently, it controls several sets of second lead screws 40249 to rotate. With the threaded connection between the second lead screws 40249 and the slider 40248, the slider 40248 drives the movable sleeve 40243 to move away from the motor 4023, thereby expanding the cleaning area. Then, it controls the motors 4023 to drive the rotating shaft 40241 to rotate, causing several sets of rubber magnets 4024... 5. Under the action of centrifugal force, it is thrown out, so that the adsorption pad 40246 can adsorb the impurities attached to the top of the textile. Then, the adaptive detection mechanism 4 is controlled to continue to descend, so that several sets of biting teeth 12 move through the corresponding biting grooves 409. By controlling several sets of tension adjustment plates 7 to move horizontally, different tension areas are formed on the textile. Then, the blower 403 is controlled to spray air through several sets of air jets 406. After the airflow passes through different tension areas of the textile, it is detected by the wind pressure sensor 11 set in a rectangular array.

[0035] By controlling the synchronous movement of the two sets of translation plates 9, the corresponding tension adjustment plates 7 move horizontally. Since each set of tension adjustment plates 7 has several sets of interlocking teeth 12 arranged in a diamond shape on its top, when the sets of tension adjustment plates 7 reciprocate, the wrinkles on the textile can be smoothed out. Furthermore, the several sets of interlocking teeth 12 on the top of the sets of tension adjustment plates 7 can clamp and fix the textile. By controlling the horizontal position of the sets of translation plates 9, different areas on the textile are made to form different tensions. This allows the testing device to simultaneously test the air permeability of the textile under different tensions, improving the testing efficiency of the testing device while reducing the interference of textile wrinkles on the test results.

[0036] Several sets of biting teeth 12 enter a corresponding set of biting grooves 409, thereby forming a multi-segment biting fixation of the textile, avoiding wrinkles when adjusting the textile to form different tension areas. Since several sets of isolation plates 404 are damped slidingly connected in two sets of sliding grooves 407, several sets of translation plates 9 can drive the corresponding isolation plates 404 to move horizontally during horizontal movement, so that different tension detection areas on the textile are in independent spaces, avoiding mutual interference of airflow and improving the detection accuracy of the detection device.

[0037] By controlling the electric push rod 3 to drive the adaptive detection mechanism 4 to descend above the textile, several sets of motors 4023 are then controlled to drive several sets of cleaning modules 4024 to rotate from their respective mounting slots 4022 to a horizontal position. Subsequently, the movable sleeve 40243 is controlled to move towards the end away from the motor 4023, thereby expanding the cleaning area. Then, the motor 4023 is controlled to drive the rotating shaft 40241 to rotate, causing several sets of rubber magnets 40245 to be thrown out under the action of centrifugal force. This allows the adsorption pad 40246 to adsorb impurities attached to the top of the textile. Combined with the reciprocating motion of several sets of biting teeth 12 to clean impurities on the bottom of the textile, the interference of impurities attached to the textile on the detection results is reduced, and the effectiveness of the detection device is improved.

[0038] Textiles can be fed through two sets of conveying mechanisms 8. At the input end, the textiles form two sets of bending areas through the first conveying roller 803 and the second conveying roller 804. The bending areas can adhere to part of the outer wall of the first conveying roller 803 and the second conveying roller 804. Water in the storage chamber 808 is atomized by an atomizing pump and sprayed out through several sets of conveying holes 806 through the corresponding conveying chamber 805, changing the humidity of the textiles. The humidity sensor on the first conveying roller 803 then monitors the humidity, enabling the detection device to adjust the humidity of the textiles in real time, thereby realizing the detection of the air permeability of textiles under different humidity levels.
