DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-6 As shown, an embodiment of the present invention provides a device for detecting air permeability of clothing fabrics, comprising:

[0027] The support frame 1 has a plurality of pads 29 fixedly connected to the lower end surface of the support frame 1, and the lower end surfaces of the plurality of pads 29 are provided with anti-slip grooves, which improves the stability of the device. Two hydraulic devices 2 are installed on the support frame 1. The hydraulic device 2 is a prior art and is composed of a power element hydraulic pump, an actuator hydraulic cylinder, a control element directional valve, an auxiliary element, an oil tank, an oil filter, and hydraulic oil. Its driving principle is based on Pascal's law. The hydraulic pump converts mechanical energy into oil pressure energy, which is transmitted to the hydraulic cylinder through a closed pipeline to push the piston to move. The product of the piston force area and the pressure generates thrust. The flow direction, pressure and flow of the oil are controlled by the regulating valve, and finally converted into linear or rotational motion of the load, thereby realizing precise displacement and power output, and can drive the first sealing cover 4 and the second sealing cover 5 to approach each other. I will not go into details here. The two hydraulic devices 2 are symmetrically arranged;

[0028] A rotating assembly is installed on the support frame 1, and two placement frames 3 are installed on the rotating assembly, one of the placement frames 3 is fixedly connected to a sealing ring 28, and the other placement frame 3 is provided with a sealing groove, the sealing ring 28 matches the sealing groove, and the two sealing plates 22 and the two placement frames 3 are provided with sealing gaskets, the sealing plates 22 are arranged in a mouth shape, and the sealing gasket layer is made of soft rubber, which improves the sealing between the two placement frames 3 and the sealing between the sealing plates 22 and the two placement frames 3, thereby ensuring the accuracy of the device detection. The first sealing cover 4 and the second sealing cover 5 are respectively fixedly installed on the two hydraulic devices 2, and the first sealing cover 4 is provided with a smoothing assembly;

[0029] A sealing assembly is installed on the first sealing cover 4 and the second sealing cover 5, and a cleaning assembly is installed on the two placement frames 3.

A rotating gear 9 is installed on the two one-way bearings, and the two reciprocating screws 7 are respectively installed on the two one-way bearings;

[0030] Two racks 10 are fixedly connected to the first sealing cover 4, and the two racks 10 are matched with the two rotating gears 9 respectively. A dust suction device 11 is installed on the first sealing cover 4 and the second sealing cover 5. The dust suction device 11 is a prior art. The dust suction device 11 consists of a driving device, a high-speed fan, a filtering system, a dust collecting container, a suction nozzle and a duct. Its working principle is based on the motor driving the fan to rotate, forming a low-pressure area inside the device, and the external air carrying dust and impurities is sucked in through the suction nozzle; after the high-speed airflow enters the dust collecting container, the flow rate drops sharply, large particles settle due to gravity, and fine particles are intercepted and filtered by the filter screen, and the purified air is discharged through the exhaust port. The filter screen and the sealing structure ensure that dust does not flow back, thereby realizing gas-solid separation and adsorption of impurities in the first sealing cover 4 and the second sealing cover 5. I will not go into details here;

[0031] The rotating assembly includes a first motor 12 fixedly mounted on the support frame 1, a rotating disk 13 is rotatably connected to the support frame 1, a rotating end of the first motor 12 is fixedly connected to the rotating disk 13, the inner wall of the rotating disk 13 is rotatably connected to the rotating frame 14, a plurality of lifting slots 15 are opened on the rotating frame 14, one of the placement frames 3 is slidably connected in the plurality of lifting slots 15, one of the lifting slots 15 inner wall is rotatably connected to a one-way screw 16, the one-way screw 16 threadedly passes through one of the placement frames 3, a second motor 17 is fixedly mounted on the rotating frame 14, and the second motor 17 is fixedly mounted on the rotating frame 14. The rotating end of the machine 17 is fixedly connected to the one-way screw 16, and the other placement frame 3 is fixedly connected to the rotating frame 14. The smoothing assembly includes two movable grooves 18 opened on the first sealing cover 4, and two movable frames 31 are slidingly connected between the two movable grooves 18. Smoothing rollers 19 are installed on the two movable frames 31. A bidirectional screw 20 is installed in one of the movable grooves 18, and the bidirectional screw 20 threads pass through the two movable frames 31. A third motor is fixedly installed on the side wall of the first sealing cover 4, and the rotating end of the third motor is fixedly connected to the bidirectional screw 20.

[0032] The sealing assembly includes two mounting grooves 21 respectively opened on the first sealing cover 4 and the second sealing cover 5, and sealing plates 22 are slidably connected in the two mounting grooves 21. The inner walls of the two mounting grooves 21 are fixedly connected to multiple springs 23. The two sealing plates 22 are fixedly connected to the multiple springs 23 respectively. The two sealing plates 22 are symmetrically arranged. The inner wall of the first sealing cover 4 is fixedly connected to a connecting frame 24, and a detection plate 25 is installed on the connecting frame 24. A wet phenolphthalein test paper is provided on the detection plate 25. An air pump 26 is fixedly installed on the side wall of the second sealing cover 5. The air pump 26 is a prior art and mainly consists of a cylinder, a movable The piston is composed of a piston, a crank-connecting rod mechanism, an intake valve, an exhaust valve and a driving device. The gas transmission principle relies on the reciprocating motion of the piston. When the piston moves downward, the cylinder volume increases to form a negative pressure, and the external gas is sucked in through the opened intake valve. When the piston moves upward, the volume decreases, the gas is compressed and pushes open the exhaust valve to enter the second sealing cover 5. The air inlet end of the air pump 26 is connected to the air storage tank, which will not be described here. The air outlet end of the air pump 26 is connected to the second sealing cover 5. An observation port is opened on the first sealing cover 4, and a glass observation window 27 is provided in the observation port to facilitate the user to observe whether the phenolphthalein test paper changes color, thereby making a judgment.

[0033] The detailed working process of the present invention is as follows:

[0034] Place the device at the designated position, then place the fabric on the placement frame 3 below, then the second motor 17 starts working, the one-way screw 16 starts rotating, causing the upper placement frame 3 to drop, and the two placement frames 3 can cooperate with each other to clamp the fabric, then the hydraulic device 2 drives the first sealing cover 4 and the second sealing cover 5 to approach each other, during the descent of the first sealing cover 4, the rack 10 drops, and the gear 9 is rotated, the reciprocating screw 7 starts working, and the cleaning rod 8 moves back and forth, so that the bristles 30 clean the fabric to prevent impurities from affecting the detection accuracy. At the same time, the dust collection device 11 removes the cleaned dust and impurities to prevent dust from affecting the detection. When the sealing plates 22 on the first sealing cover 4 and the second sealing cover 5 are respectively attached to the two placement frames 3, the fabric is realized. In a sealed testing environment, the two smoothing rollers 19 can fit together and apply thrust to the fabric to make the fabric taut. At this time, the third motor drives the bidirectional screw 20 to work, and the two smoothing rollers 19 move away from each other to smooth the fabric, which can avoid local tiny gaps in the fabric caused by wrinkles, thereby improving the accuracy of the test results. Subsequently, the air pump 26 inputs alkaline gas into the second sealing cover 5. If the gas passes through the fabric, the phenolphthalein test paper will change color, and the air permeability of the fabric can be tested. After the air tightness test on one side of the fabric is completed, the hydraulic device 2 drives the first sealing cover 4 and the second sealing cover 5 to reset, and then the first motor 12 drives the rotating frame 14 to rotate, so that the fabric can be flipped over and tested again to avoid missing the inner structure damage due to single-sided testing, thereby improving the accuracy of the test.
