[0014] Preferably, brackets are fixedly installed on both the front and rear sides of the U-shaped frame, and a positioning shaft is rotatably installed inside the brackets.

[0015] The beneficial effects of this invention are as follows: In this invention, a textile air permeability testing device is described. The textile is placed in two U-shaped frames at its top and bottom ends. A knob is rotated to rotate a screw, which, through its threaded engagement with the U-shaped frames, causes the U-shaped plate to slide within the frames, bringing the first clamping plate closer to the second clamping plate. This allows the first and second anti-slip pads to clamp and fix the textile. A fan is activated to extract air from the chamber through the inlet pipe and guide it into the outlet box through the outlet pipe. Finally, the air is ejected through the outlet nozzle on the outlet box and blown onto the textile. The airflow passes through the textile and blows onto the baffle plate 9, causing it to move to the left and compress the return spring. The baffle plate, through its contact with the abutment plate, moves the horizontal plate and pointer to the left. The air permeability of the textile is determined by observing the pointer's position on the scale. In this invention, a textile air permeability testing device is described. By starting a drive motor to drive a lead screw to rotate, the lead screw drives the connecting plate to move up and down through threaded transmission with the connecting plate and under the guidance of the second slide rail. The connecting plate drives the mounting plate, the wind baffle plate and the box to move up and down through the L-plate and the connecting frame, thereby realizing the air permeability testing of textiles at different positions. In this invention, a textile air permeability testing device is described. When the textile is pushed by the wind, the two ends of the textile pull two U-shaped frames slightly closer to each other. The guide plate moves synchronously through the vertical plate, which compresses the compression spring. The pressure sensor monitors the pressure on the compression spring, thereby monitoring the tension of the textile during the testing process to determine the magnitude of the test wind force. By analyzing the changes in tension, it can be determined whether the textile has loosened or fallen off. Furthermore, when the two U-shaped frames approach each other, the connecting column is moved by the square plate, so that the connecting column moves vertically in the waist-shaped hole and moves to the left, and the second clamping plate moves to the left by the square plate, which further enhances the clamping force on the textile and prevents the textile from falling off during the inspection process. In this invention, a textile air permeability testing device, during the testing process, a contact plate drives a conductive plate to move synchronously to the left, while a baffle plate drives a resistance strip to move synchronously to the left via a crossbar. When the air outlet box moves to the position where the textile has wrinkles, the actual wind resistance generated by the textile increases, reducing the thrust on the baffle plate. Under the action of a return spring, the baffle plate returns to its original position and moves to the right, while the crossbar remains stationary under the action of the friction pad, keeping the conductive plate stationary. The baffle plate, via the crossbar, drives the resistance strip to move to the right, allowing the resistance strip to insert into the through hole. The heating element is activated to heat and evaporate the water pre-stored in the chamber. The steam is then guided into the exhaust box by a fan and sprayed out to remove wrinkles from the textiles. The greater the wrinkles in the textiles, the greater the wind resistance, which increases the distance the resistance strip moves relative to the conductive plate. This reduces the resistance of the resistance strip connected to the heating element, increases the heating power of the heating element, and improves the heating effect on the water. This increases the amount and temperature of steam generated, thus avoiding the impact of textile wrinkles on the air permeability test and facilitating subsequent tests and use. The textile air permeability testing device of the present invention can realize the automated air permeability testing of textiles through the positioning mechanism, air outlet component and monitoring mechanism, and can conveniently and intuitively observe the test results. It can also automatically remove wrinkles when textile wrinkles occur, so as to avoid affecting the air permeability test results. Attached Figure Description

The square plate 309 is slidably connected in the corresponding square hole, thereby guiding the square plate 309 and the second clamping plate 302.

[0022] In this embodiment, two vertical plates 803 are fixedly installed on the opposite sides of the two U-shaped frames 3. The other ends of the two vertical plates 803 on the same side are fixedly installed with the same guide plate 801. The two guide plates 801 are slidably connected in the corresponding mounting boxes 8. A compression spring 802 is fixedly installed on the opposite side of the two guide plates 801. A pressure sensor is fixedly installed on the other end of the compression spring 802. The pressure sensor is fixedly installed in the corresponding mounting box 8. The pressure sensor can monitor the pressure borne by the compression spring 802.

[0023] In this embodiment, a drive mechanism for synchronously lifting and lowering the housing 4 and the mounting plate 7 is provided on the top rear side of the base 1. The drive mechanism includes: a drive motor 10, a lead screw 1001, a connecting plate 1002, a connecting frame 6, and an L-plate 401. The connecting frame 6 is fixedly installed on the rear side of the mounting plate 7, the L-plate 401 is fixedly installed on the rear side of the housing 4, the connecting plate 1002 is fixedly installed on the rear side of the connecting frame 6 and the L-plate 401, and the connecting plate 1002 is threaded onto the outside of the lead screw 1001. The bottom end of the lead screw 1001 is fixedly installed on the output shaft of the drive motor 10, and the drive motor 10 is fixedly installed on the top of the base 1.

[0024] In this embodiment, first slide rails 201 are fixedly installed on both sides of the fixed frame 2. The L-plate 401 and the connecting frame 6 are slidably sleeved on the outer side of the corresponding first slide rails 201, thereby guiding the connecting frame 6 and the L-plate 401 to move up and down. Two positioning plates and two second slide rails 202 are fixedly installed on the rear side of the fixed frame 2. The two positioning plates are rotatably sleeved on the outer side of the lead screw 1001. The positioning plates rotate and position the lead screw 1001, making its operation more stable. The connecting plate 1002 is slidably sleeved on the outer side of the two second slide rails 202. The second slide rails 202 guide the connecting plate 1002 to move up and down, thereby making its movement more stable.

[0025] In this embodiment, a water inlet is provided on the top of the housing 4, and a sealing plug 402 is movably inserted into the water inlet. When monitoring work is carried out, the sealing plug 402 can be opened to pre-store water into the housing 4 through the water inlet for subsequent use. An air inlet is provided on one side of the housing 4 to facilitate the free flow of air in the housing 4. An air outlet box 5 is fixedly installed on the other side of the housing 4, and a fan 503 is fixedly installed on the top of the housing 4.

[0026] In this embodiment, a guide rod 901 and a return spring 902 are fixedly installed on the left side of the wind deflector 9. The other end of the return spring 902 is fixedly connected to the connecting frame 6. The connecting frame 6 is slidably sleeved on the outside of the guide rod 901, thereby guiding and resetting the wind deflector 9. The return spring 902 needs to be a spring with a small stiffness coefficient, so that the wind deflector 9 can overcome the elastic deformation pressure of the return spring 902 and move when pushed by the wind, so as to facilitate intuitive observation. In addition, multiple air leakage holes are opened on one side of the connecting frame 6 to ensure ventilation and reduce the impact on wind flow. The mounting plate 7 has a vertical hole at its top, and a pressure plate 16 is slidably installed in the vertical hole. A friction pad 1601 is fixedly installed at the bottom of the pressure plate 16. The friction pad 1601 movably abuts against the top of the horizontal plate 13. A compression spring 1602 is fixedly installed at the top of the pressure plate 16, and a limit plate 1603 is fixedly installed at the top of the compression spring 1602. The limit plate 1603 is fixedly installed in the vertical hole. The compression spring 1602 is initially in a compressed state, which can keep the friction pad 1601 pressing the horizontal plate 13 with a certain force, so that the horizontal plate 13 can remain in its original position without external force, thus making it convenient to observe the position of the pointer 14 pointing to the scale 15.

[0027] In this embodiment, an insulating rod is fixedly installed at the bottom of the crossbar 18, and a conductive cylinder 19 is fixedly installed at the other end of the insulating rod. A resistance rod 20 is fixedly installed on one side of the mounting plate 7. The conductive cylinder 19 is slidably sleeved on the outside of the resistance rod 20. The right end of the resistance rod 20 and the conductive cylinder 19 are connected to the circuit of the drive motor 10. The area to the right of the conductive cylinder 19 on the resistance rod 20 is connected in series to the circuit of the drive motor 10. A bracket 313 is fixedly installed on both the front and rear sides of the U-shaped frame 3. A positioning shaft 308 is rotatably installed inside the bracket 313. The positioning shaft 308 can guide the textile when it bends or deforms.

[0028] In this embodiment, during use, the upper and lower ends of the textile are placed in two U-shaped frames 3 respectively. Then, the knob 306 is rotated to drive the screw 305 to rotate. The screw 305 drives the U-shaped plate 307 to slide in the U-shaped frame 3 through the threaded engagement with the U-shaped frame 3, and drives the first clamping plate 301 to move closer to the second clamping plate 302, so that the first anti-slip pad 303 cooperates with the second anti-slip pad 304 to clamp and fix the textile. By starting the fan 503, the air in the box 4 is drawn out through the air inlet pipe and introduced into the air outlet box 5 through the air outlet pipe. Finally, the air is sprayed out through the air outlet nozzle 501 on the air outlet box 5 and blown towards the textile. The wind force blows through the textile towards the wind deflector 9, thereby pushing the wind deflector 9 to move to the left, thereby compressing the return spring 902. The wind deflector 9 drives the horizontal plate 13 and the pointer 14 to move to the left through the contact plate 11. The air permeability of the textile is judged by observing the corresponding position of the pointer 14 pointing to the scale 15. By starting the drive motor 10, the lead screw 1001 is rotated. The lead screw 1001 drives the connecting plate 1002 through the thread transmission with the connecting plate 1002 and is guided by the second slide rail 202. The connecting plate 1002 drives the mounting plate 7, the baffle plate 9 and the box 4 to move up and down through the L plate 401 and the connecting frame 6, thereby realizing the air permeability test of textiles at different positions. When the baffle plate 9 moves to the left, it drives the conductive cylinder 19 to move to the left through the cross bar 18 and the insulating rod, which increases the resistance of the resistance rod 20 connected to the drive motor 10, thereby reducing the power of the drive motor 10 and reducing the rotation speed of the lead screw 1001. This reduces the up and down feeding speed of the baffle plate 9 and the air outlet assembly, thus slowing down the speed of changing the detection position when the test wind force is greater, ensuring the detection effect. When the textile is pushed by the wind, the two ends of the textile pull the two U-shaped frames 3 slightly closer to each other, and the guide plate 801 moves synchronously through the vertical plate 803, thereby compressing the compression spring 802. The pressure sensor monitors the pressure on the compression spring 802, thereby monitoring the tension of the textile during the testing process to determine the magnitude of the test wind force. By analyzing the changes in tension, it can be determined whether the textile has loosened or fallen off. When the two U-shaped frames 3 approach each other, the connecting column 310 is moved by the square plate 309, so that the connecting column 310 moves vertically in the waist-shaped hole and moves to the left, and the second clamping plate 302 is moved to the left by the square plate 309, which further enhances the clamping force on the textile and prevents the textile from falling off during the inspection process. During the testing process, the contact plate 11 drives the conductive plate 12 to move synchronously to the left, while the baffle plate 9 drives the resistor strip 17 to move synchronously to the left via the crossbar 18. When the air outlet box 5 moves to the position where the textile has wrinkles, the actual wind resistance generated by the textile increases, reducing the thrust on the baffle plate 9. Under the action of the return spring 902, it returns to its original position and moves to the right, while the crossbar 13 remains stationary under the action of the friction pad 1601, keeping the conductive plate 12 stationary. The baffle plate 9 drives the resistor strip 17 to move to the right via the crossbar 18, causing the resistor strip 17 to insert into the through hole, thereby enabling the electrical... Heat pipe 23 is activated to heat and evaporate the water pre-stored in the chamber 4. The steam is then introduced into the exhaust box 5 by fan 503 and sprayed out to remove wrinkles from the textiles. The greater the degree of wrinkles in the textiles, the greater the wind resistance, which increases the distance that the resistance strip 17 moves relative to the conductive plate 12. This reduces the resistance of the resistance strip 17 connected to the heating pipe 23, increases the heating power of the heating pipe 23, and improves the heating effect on the water. This increases the amount and temperature of steam generated, thus avoiding the impact of textile wrinkles on the air permeability test and facilitating subsequent tests and use.

[0029] In this embodiment, an electric push rod 21 is fixedly installed on one side of the mounting plate 7. A reset plate 22 is fixedly installed on the output end of the electric push rod 21, and the reset plate 22 is flush with the abutment plate 11. After the test is completed, the electric push rod 21 can be started to drive the reset plate 22 to move to the right, and the reset plate 22 can push the abutment plate 11 to the right to reset. This can conveniently and automatically restore the initial state of the test equipment and avoid affecting subsequent tests.
