[0026] See also Figure 1 and 2 Preferably, the surface of the rotating rod 17 is fixedly connected to the rotating disk 14, and the surface of the rotating disk 14 is fixedly connected to a plurality of levers 16 arranged in a circular array with the rotating rod 17 as the axis; a plurality of protrusions 11 are arranged in a circular array with the center of the mounting disk 08 as the axis; a fixing plate 19 is fixedly connected to the bottom plate 01, and a slide groove 29 is provided on the fixing plate 19, and a slide plate 28 is slidably connected in the slide groove 29, and a moving plate 26 is fixedly connected to the surface of the slide plate 28, and the moving plate The upper shifting block 15 and the lower shifting block 27 are fixedly connected to the upper shifting block 15 and the lower shifting block 27, the angles of which are opposite to each other and the inclined surfaces are in the same direction, and the inclined surfaces of which are alternately pushing the protrusion 11; the connecting rod 25 is fixedly connected to the movable plate 26, and the triangular block 24 is fixedly connected to the connecting rod 25, and the shifting rod 16 can push the triangular block 24 to move; a spring 20 for pushing the triangular block 24 to reset is also provided between the triangular block 24 and the fixed plate 19.

[0027] See also Figure 2 and 3Preferably, a fixed block 32 is fixedly connected to the fixed plate 19, a through slot is provided on the fixed block 32, a sliding rod 33 is slidably connected through the through slot, one end of the sliding rod 33 is fixedly connected to the triangular block 24, and the other end thereof is fixedly connected to the wind shield 18, and one end of the sliding rod 33 close to the lever 16 is fixedly connected to the limit plate 21.

[0028] See also Figure 1 and 4 Preferably, the ratio between the thickness of the slider 10 and the diameter of the slider 10 is not less than 0.3. It is ensured that the slider 10 has sufficient thickness so as not to fall or tilt in the sampling tube 09, thereby causing air leakage, so that the wind from the air outlet pipe 06 cannot push the slider 10 to slide, thereby affecting the effect of the experimental detection.

[0029] See also Figure 1 Preferably, a hole 12 for fixing the fabric is provided on the air inlet ring 04. The webbing sample can be fixed by inserting a self-tapping screw or a staple into the hole 12.

[0030] See also Figure 4 Preferably, a limit block 31 is provided on the arc profile of the slider 10, and a limit groove 30 for limiting the sliding connection of the limit block 31 is provided on the inner wall of the sampling tube 09. The position where the limit slider 10 slides prevents it from sliding out of the sampling tube 09 during detection or reset.

[0031] On the basis of the above embodiment, further, the surface of the sampling tube 09 is provided with scales, and the sampling tube 09 is made of transparent material.

[0032] The air permeability can be judged by judging the scale when the slider 10 slides to different positions in the sampling tube 09, which is convenient for observing the experimental results and more intuitive.

[0033] On the basis of the above embodiment, further, a pull rod 23 is fixedly connected to the side surface of the slider 10 away from the mounting plate 08, and a scale is set on the pull rod 23. By judging the length of the pull rod 23 sliding out of the sampling tube 09, the air permeability of the webbing sample can be directly judged by reading the scale on the pull rod 23. And the pull rod 23 can realize the function of resetting the slider 10.

[0034] The working principle of the first embodiment of the present application is as follows: the webbing sample to be tested is placed on the side surface of the air inlet ring 04 close to the blower 22, and then the sample is fixed on the air inlet ring 04 by inserting it into the clamping hole 12 through a self-tapping screw or a clamping pin.

[0035] After the fixation is completed, the blower 22 will blow the wind in the direction of the air inlet ring 04, the blown wind will flow into the air inlet ring 04, and then flow to the air outlet pipe 06 through the air inlet ring 04, and then blow in the opposite direction to the sampling tube 09 through the air outlet pipe 06. The wind will blow the slider 10 in the sampling tube 09 to move away from the air outlet pipe 06. The ventilation performance can be directly judged by the displacement distance of the slider 10 sliding in the sampling tube 09.

[0036] Compared with traditional devices, the ventilation condition of the webbing can be judged intuitively without the need for auxiliary detection by instruments.

[0037] The power device drives the rotating rod 17 to rotate intermittently clockwise, and the rotation angle is the angle between the two levers 16 (please refer to the attached figure for details). Figure 1 ), when the rotating rod 17 rotates, it will drive the clamping hole 12 to rotate on the supporting plate 02 through the rotating shaft 03. Whenever the rotating rod 17 rotates the angle between the two levers 16, it will drive the clamping hole 12 to rotate synchronously by the same angle. At this time, the rotating rod 17 will also drive the turntable 14 to rotate synchronously by the angle between the two levers 16. The rotation of the rotating rod 17 will drive the lever 16 to rotate at the same time. When the lever 16 rotates, it will push the triangular block 24 downward on the fixing plate 19 to slide toward the mounting plate 08, so that the triangular block 24 will push the wind shield 18 to move synchronously, thereby blocking the air outlet pipe 06 and preventing it from continuing to discharge air.

[0038] The wind shield 18 can effectively prevent the airflow from interfering with the detection data of the sampling tube 09 located directly opposite to the air outlet pipe 06 when the mounting plate 08 rotates, thereby ensuring the accuracy of the detection data.

[0039] See here Figure 2 When the triangular block 24 drives the wind deflector 18 to move in the direction of the mounting plate 08, the movable plate 26 will be driven to move through the connecting rod 25. The movement of the movable plate 26 will drive the upper shift block 15 and the lower shift block 27 to move synchronously. When the movable plate 26 moves in the direction of the mounting plate 08, the upper shift block 15 will push the protrusion 11 to rotate clockwise once by the angle of the spacing angle between the two protrusions 11. When the shift rod 16 moves over the triangular block 24 and is disconnected from it, the limit plate 21 will be pushed under the reset action of the spring 20 to push the triangular block 24 to slide on the fixed plate 19 in the direction away from the mounting plate 08 for reset. At this time, the triangular block 24 will drive the connecting rod 25 to pull the movable plate 26 to move synchronously, and the movable plate 26 will drive the lower shift block 27 to move in the direction away from the mounting plate 08, so that the lower shift block 27 will push the mounting plate 08 to rotate clockwise once again by the angle of the spacing angle between the two protrusions 11.

[0040] At this time, the sampling cylinder 09 that has collected data moves away from the position facing the air outlet pipe 06 , and the next sampling cylinder 09 rotates again to the position facing the air outlet pipe 06 , and the next lever 16 will rest against the triangular block 24 again.

[0041] Therefore, a new sampling tube 09 can be replaced every time the air inlet ring 04 rotates intermittently by an angle, so as to detect the ventilation condition of the webbing at the new angle. In addition, the wind shield 18 can prevent the sampling tube 09 that has already collected data from being disturbed when the angle is switched and the sampling tube 09 is replaced after the single angle experimental data detection is completed.

[0042] Compared with traditional devices, it can detect the ventilation conditions of the ribbon at different angles, and can collect and classify the experimental data of ventilation conditions at different angles. And compare with the observed experimental results. And it can ensure that the collected experimental data will not be disturbed.

[0043] After data collection, the power device drives the rotating rod 17 to reset to the initial angle, pushing the slider 10 toward the direction close to the mounting plate 08 until the limit block 31 on the slider 10 reaches the end of the limit groove 30 close to the mounting plate 08, completing the reset of the entire device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
