One end of the piston tube 18 extends out of the air source movable seat 15 and is provided with a compression air supply block 17. One side of the compression air supply block 17 is in contact with the inner circumference of the rotating sleeve 6. The center of the compression air supply block 17 passes through the piston tube 18 to provide an inspection and supply groove 20. The movable seat 16 of the detection module is penetrated by a detection air groove 21. One side of the rotating sleeve 6 is penetrated by a plurality of air holes 22. When the inspection and supply groove 20, the detection air groove 21 and the air holes 22 are in the same horizontal position, it is in the detection state, and the fabric is located between the movable seat 16 of the detection module and the rotating sleeve 6; when the control cylinder 37 pushes the second support beam 11, the second support beam 11 can be made close to the rotating sleeve 6, thereby realizing the clamping of the fabric by the cooperation of the second support beam 11 and the rotating sleeve 6.

One side of 17 is provided with a reset spring 27. When the air permeability test of the fabric is required, the conveying movement of the fabric is appropriately decelerated, and then the rotation position of the rotating sleeve 6 is determined by the cooperative induction of the PLC and the position sensor. When the air hole 22 is between the detection air groove 21 and the inspection air groove 20, the second support beam 11 is pushed close to the rotating sleeve 6 by the control cylinder 37. At this time, the movable seat 16 of the detection module quickly squeezes the fabric and the rotating sleeve 6 to achieve a tight contact, and then as the control cylinder 37 continues to push, the fabric is pressed and sealed. The second support beam 11 pushes the self-rotating sleeve 6, the first support beam 5 and the adaptive movable seat 7 to move horizontally along the support guide rod 9 and the movable slide rail 8, and the moving speed of the adaptive movable seat 7 can overcome the position distance of the normal fabric winding, and keep the fabric relatively still between the detection module movable seat 16 and the self-rotating sleeve 6.

After entering, the high-pressure gas will first fill in a number of piston grooves 23, push a number of pressing piston rods 26, and then press The compact air supply block 17 is squeezed on the inner wall of the rotating sleeve 6 to seal the inner side of the stationary rotating sleeve 6. Similarly, when the high-pressure gas is released, the compact air supply block 17 does not contact the rotating sleeve 6, and does not cause unnecessary wear. Then the high-pressure airflow continues to increase. When the gas pressure reaches the detection airflow pressure, the piston tube 18 will be opened, and the high-speed airflow enters the detection air supply groove 20 through the movable sealing groove 19, and then contacts the fabric from the air vent 22, and then contacts the detection module from the detection air groove 21 to realize the acquisition of permeability detection data.

An adjusting worm 30 is rotatably provided on the bearing support frame. One side of the adjusting worm 30 is meshed with the worm gear 29. A prismatic slot 31 is provided horizontally through the center of the adjusting worm 30. The two adjusting worms 30 A prismatic drive rod 36 is inserted into the prismatic slot 31, and the length of the prismatic drive rod 36 is greater than the horizontal movable length of the first support beam 5 and the second support beam 11. When the prismatic drive rod 36 rotates, the prismatic drive rod 36 controls the two adjusting worms 30 to rotate synchronously. At this time, the rotation of the adjusting worm 30 can drive the adjusting screw 14 connected to the worm gear 29 to rotate, and then the air source movable seat 15 and the detection module movable seat 16 can move horizontally in the first support beam 5 and the second support beam 11. Through the cooperation of the PLC and the sensor module, the air source movable seat 15 and the detection module movable seat 16 can be accurately docked with the air vent 22. In addition, the size of the air vent 22 is slightly larger than the size of the inspection air groove 20 and the detection air groove 21, so that a slight deviation will not affect the breathability detection of the fabric.

[0024] Embodiment 2: On the basis of embodiment 1, a mechanical auxiliary docking assembly is provided to stabilize the docking of the vent hole 22 with the inspection and delivery gas slot 20 and the inspection gas slot 21. The mechanical auxiliary docking assembly includes two conical docking blocks 33. The two conical docking blocks 33 are respectively inserted into the two sides of the rotating sleeve 6.

Although the control cylinder 37 can be controlled in time to press the rotating sleeve 6 and the fabric when the air vent 22 is between the inspection and delivery air groove 20 and the detection air groove 21 through PLC control, when the signal fails or is slightly delayed, the second support beam 11 is close to the self-rotating sleeve 6, and the conical docking block 33 can be directly inserted into the auxiliary docking groove 32, and then the self-rotating sleeve 6 is straightened under the action of the conical structure of the conical docking block 33, so that the air vent 22 can be accurately positioned with the inspection and delivery air groove 20 and the detection air groove 21 under mechanical control.
