[0017] By setting up auxiliary components and utilizing the duct to actively limit the position of the sucked air, during the process of sucking air, the suction force generated by the sucked airflow can be utilized to adsorb the released fabric into the interior of the storage chamber, and after the fan is turned off, the fabric falls into the storage chamber under the action of gravity and is stored. The staff can remove the uniformly stored fabric by removing the cover plate. The operation is simple and there is no need to unload the fabric. The staff only needs to place the fabric to be tested to cover the through hole, which effectively improves the detection efficiency and is suitable for batch fabric detection.

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 below.

[0028] like Figure 1-Figure 7 The device for detecting air permeability of clothing fabrics shown in the figure comprises a workbench 1, a console 101 is arranged on the top of the workbench 1, a shell 2 located on one side of the console 101 is fixedly connected to the top of the workbench 1, a placement opening is provided on the surface of the shell 2, a motor 102 is provided inside the workbench 1, a mounting cavity is provided on the top of the workbench 1, an air permeability detection device 103 is provided inside the mounting cavity, a limit component 4 is provided inside the shell 2, and an auxiliary component 3 is provided on the top of the shell 2;

[0029] Among them, the limiting component 4 includes a rotating block 405 arranged inside the outer shell 2, the bottom of the rotating block 405 is fixedly connected to the output shaft of the motor 102, the surface of the rotating block 405 is fixedly connected to the turntable 401, the surface of the turntable 401 is provided with evenly distributed through holes, the surface of the turntable 401 is provided with grooves 403 coaxially arranged with the through holes, and the surface of the turntable 401 is fixedly connected to partitions 402 staggered with the through holes.

[0030] The clothing fabric is placed on the turntable 401 through the placement opening and covers the through hole. By starting the motor 102, the rotating block 405 can be driven to rotate, thereby driving the turntable 401 to rotate, so as to achieve the effect of changing the position of the placed clothing fabric.

[0031] like Figure 1-Figure 7 As shown, the two partitions 402 directly form a detection cavity, and a connecting ring 404 is arranged inside the detection cavity. A slide plate 407 is fixedly connected to the surface of the connecting ring 404, and the other end of the slide plate 407 is slidably connected to the inner wall of the rotating block 405. An adjusting rod 408 is fixedly connected to the bottom of the slide plate 407, and the lower end of the adjusting rod 408 passes through the rotating block 405.

[0032] A fixing ring 415 coaxially arranged with the rotating block 405 is embedded on the top of the workbench 1 , a guide ring 416 is fixedly connected to the inner side of the fixing ring 415 , and the lower end of the adjusting rod 408 contacts the surface of the guide ring 416 .

[0033] A first spring 406 is fixedly connected to the bottom of the slide plate 407 , and the other end of the first spring 406 is fixedly connected to the inner bottom wall of the rotating block 405 .

[0034] The bottom of the connecting ring 404 is fixedly connected with a mounting ring 409 , the inner side of the mounting ring 409 is embedded with a sealing ring 410 , the inner wall of the mounting ring 409 is slidably connected with an extrusion ring 411 , the top surface of the extrusion ring 411 is inclined, and the extrusion ring 411 is located below the sealing ring 410 .

[0035] The bottom of the extrusion ring 411 is fixedly connected with evenly distributed mounting rods 414 , the bottom of the mounting ring 409 is provided with a trigger plate 412 , and the lower end of the mounting rod 414 passes through the mounting ring 409 and is fixedly connected with the top of the trigger plate 412 .

[0036] A second spring 413 is sleeved on the surface of the mounting rod 414 . The upper end of the second spring 413 is fixedly connected to the bottom of the mounting ring 409 , and the lower end of the second spring 413 is fixedly connected to the top of the trigger plate 412 .

[0037] During the rotation of the rotating block 405, the connecting ring 404 can be driven to move synchronously through the sliding plate 407. The first spring 406 is configured to keep the bottom of the adjusting rod 408 always in contact with the top surface of the guide ring 416. As the rotating block 405 rotates, the adjusting rod 408 is guided to move downward through the cooperation of the guide ring 416 and the first spring 406, thereby driving the connecting ring 404 to move downward synchronously. In this process, the mounting ring 409 is driven to be inserted into the interior of the groove 403, so that the clothing fabric exceeding the cross-section of the through hole is driven to be inserted into the interior of the groove 403 through the mounting ring 409. Moreover, as the mounting ring 409 is inserted, the mounting rod 414 can be driven to be inserted into the mounting hole through the trigger plate 412 under the obstruction of the inner bottom wall of the groove 403. The inside of the ring 409 drives the extrusion ring 411 to apply pressure to the sealing ring 410. In this process, the sealing ring 410 can be squeezed and deformed. Since the top surface of the extrusion ring 411 is set in an inclined surface, it can drive the sealing ring 410 to squeeze the fabric to fit the inner wall of the groove 403 when it is deformed, so as to improve the effect of limiting the fabric and avoid the fabric deviation during the air permeability test. At the same time, the fabric is driven to be inserted into the inside of the groove 403 by the installation ring 409, which can stretch the fabric and reduce the influence of wrinkles on the air permeability test, thereby effectively enhancing the effect of the air permeability test. After the test is completed, the limit on the fabric can be released under the cooperation of the adjusting rod 408, the first spring 406, the slide plate 407 and the guide ring 416, so as to separate the fabric.

[0038] like Figure 1-Figure 7As shown, the auxiliary component 3 includes a mounting shell 301 arranged on the top of the outer shell 2, a fan 304 is arranged inside the mounting shell 301, an air duct 302 is connected to the bottom of the mounting shell 301, the air duct 302 corresponds to the air permeability detection device 103, and a conduit 303 is connected to the top of the mounting shell 301. The auxiliary component 3 also includes a connecting block 305 fixedly connected to the surface of the outer shell 2, a storage cavity 306 connected to the outer shell 2 is provided inside the connecting block 305, the angle between the connecting block 305 and the placement port is ninety degrees, the angle between the connecting block 305 and the mounting shell 301 is ninety degrees, and a detachable cover plate 307 is provided on the other side of the connecting block 305.

[0039] By starting the fan 304, the airflow can be guided to blow air to the limited fabric through the air guide tube 302, the connecting ring 404 and the mounting ring 409, and the airflow can pass through the fabric for detection through the air permeability detection device 103, wherein the air permeability detection device 103 is a relatively mature component in the prior art application and will not be described in detail here. In addition, since the setting of the conduit 303 limits the position of the inhaled gas, the gas can be sucked out through the storage chamber 306 and the detection chamber connected thereto. In this process, the suction force generated when the airflow is sucked can be used to adsorb the fabric that has been released from the limit to the inside of the storage chamber 306, and after the fan 304 is turned off, the fabric falls into the storage chamber 306 under the action of gravity for storage. The staff can remove the uniformly stored fabric by disassembling the cover plate 307. The operation is simple and there is no need to unload the material. The staff only needs to place the fabric to be tested to cover the through hole, which effectively improves the detection efficiency and can be applied to the detection of batch fabrics.

[0040] Working principle: the clothing fabric is placed on the turntable 401 through the placement opening and covers the through hole. By starting the motor 102, the rotating block 405 can be driven to rotate, thereby driving the turntable 401 to rotate, so as to achieve the effect of changing the position of the placed clothing fabric. In this process, the connecting ring 404 can be driven to move synchronously through the slide plate 407. The first spring 406 is set to keep the bottom of the adjusting rod 408 always in contact with the top surface of the guide ring 416. The top surface of the guide ring 416 is close to the position of the auxiliary component 3. As the rotating block 405 rotates, the guide ring 416 and the first spring 406 are used to move the connecting ring 404 synchronously. The adjusting rod 408 is guided to move downward under the cooperation of the guide rings 416. Specifically, the height of the top surface near the air guide tube 302 gradually decreases, so that the adjusting rod 408 can be driven to cooperate with the top surface of the guide ring 416 to guide the adjusting rod 408 downward under the action of the first spring 406, thereby driving the connecting ring 404 to move downward synchronously. In this process, the mounting ring 409 is driven to be inserted into the interior of the groove 403, so that the clothing fabric exceeding the cross-section of the through hole is driven to be inserted into the interior of the groove 403 through the mounting ring 409, so as to achieve the effect of automatically limiting the fabric, without manual operation by the staff, and the operation is simple. , and with the insertion of the mounting ring 409, the mounting rod 414 can be driven to be inserted into the mounting ring 409 through the trigger plate 412 under the obstruction of the inner bottom wall of the groove 403, thereby driving the extrusion ring 411 to apply pressure to the sealing ring 410. In this process, the sealing ring 410 can be squeezed and deformed, and because the top surface of the extrusion ring 411 is set in an inclined surface, the sealing ring 410 can be driven to squeeze the fabric to fit the inner wall of the groove 403 when deforming, so as to achieve the effect of improving the position limitation of the fabric and avoid the fabric from shifting during the air permeability detection process. By setting the auxiliary component 3, under the action of the conduit 303 The position of the inhaled gas is restricted so that the gas can be sucked out through the storage chamber 306 and the detection chamber connected thereto. In this process, the suction force generated when the airflow is sucked can be used to adsorb the fabric whose limit is released into the interior of the storage chamber 306, and after the fan 304 is turned off, the fabric falls into the storage chamber 306 under the action of gravity for storage. The staff can remove the cover plate 307 to take out the uniformly stored fabric. The operation is simple and there is no need to unload the material. The staff only needs to place the fabric to be tested to cover the through hole, which effectively improves the detection efficiency and is suitable for batch fabric detection.
