The air inlet end of the air delivery fan 206 is connected to the aerosol box 205, and a first electrically-controlled valve 207 is fixedly installed on the output end of the air delivery fan 206. An air delivery pipe 208 is fixedly installed on the first electrically-controlled valve 207. The fog can be transported to the interior of the air delivery pipe 208 by opening the first electrically-controlled valve 207 and the air delivery fan 206. The fog can be transported into the interior of the air delivery pipe 208 by connecting the air delivery pipe 208 to the woven bag. An air pressure sensor 209 is fixedly installed in the air delivery pipe 208. The air pressure sensor 209 can detect the air pressure inside the air delivery pipe 208, and then detect the air pressure inside the woven bag. The airtightness detection device also includes an air return component, through which the water vapor entering the woven bag can be extracted.

[0020] Further, the air return assembly includes an exhaust pipe 210 fixedly mounted on the frame 1, the exhaust pipe 210 is connected to the air supply pipe 208, a second electrically controlled valve 211 is fixedly mounted on one end of the exhaust pipe 210, an exhaust fan 212 is fixedly mounted on the frame 1, the input end of the exhaust fan 212 is connected to the second electrically controlled valve 211, an air supply pipe 213 is fixedly mounted on the output end of the exhaust fan 212, and the other end of the air supply pipe 213 is connected to the bottom of the water tank 201 through a one-way valve. After the inspection of the woven bag is completed, the first electrically controlled valve 207 is closed and the second electrically controlled valve 211 is opened, and the exhaust fan 212 is started at the same time, so that the air supply pipe 208 can generate suction to the inside of the woven bag, thereby sucking out the water mist inside the woven bag, and the water mist enters the inside of the water tank 201 through the air supply pipe 213, so that the water mist can be recycled, and the one-way valve can prevent the water inside the water tank 201 from entering the inside of the air supply pipe 213.

[0021] This embodiment also includes a sealing component 3, which is installed on the frame 1. The sealing component 3 fixes and seals the opening of the woven bag. The sealing component 3 includes a tensioning mechanism for tensioning the openings of woven bags of different sizes, which can be applied to woven bags of different opening sizes, and can improve the applicability of the device. The sealing component 3 also includes an airbag pressing module, which seals the woven bag. That is, it can prevent water mist from overflowing through the opening of the woven bag, and ensure the stability of the woven bag during airtightness detection.

[0022] Further, the tensioning mechanism includes a slide rail 301 fixedly mounted on the frame 1, and sliders 302 are slidably mounted on both ends of the slide rail 301, and the sliders 302 can move along the slide rail 301, and a bidirectional screw rod 303 is rotatably mounted on the frame 1, and two sliders 302 are respectively threadedly connected to the two ends of the bidirectional screw rod 303, and a motor 304 is fixedly mounted on the frame 1, and the output shaft of the motor 304 is coaxially fixedly connected with the bidirectional screw rod 303. When the motor 304 is started, the bidirectional screw rod 303 can be driven to rotate, and the rotating bidirectional screw rod 303 can drive the sliders 302 on both sides to move synchronously in the opposite direction, and a compensation component is fixedly mounted on the slider 302, and a support rod 305 is mounted on the compensation component. When the slider 302 moves, it will drive the support rod 305 connected thereto to move, and the support rods 305 on both sides will contact the two sides in the woven bag, and the opening of the woven bag can be tensioned and fixed by moving the support rods 305 away from each other.

[0023] The airbag pressing module includes a sleeve 306 fixedly mounted on both sides of the support rod 305, a slide bar 307 is slidably mounted in the sleeve 306, and an airbag support plate 308 is fixedly mounted on the two slide bars 307 on the same side. The airbag support plates 308 on both sides can slide along the sleeve 306, so that the spacing between the airbag support plates 308 on both sides can be adjusted, which is convenient for the installation and removal of the woven bag. An airbag 309 is fixedly mounted on the airbag support plate 308, and an air delivery connector 310 is fixedly mounted on the airbag 309. The air connector 310 can transport gas into the airbag 309, or discharge the gas inside the airbag 309, thereby causing the airbag to expand or contract. The expanded airbag 309 will evenly compress the opening of the woven bag, thereby sealing the opening of the woven bag. The airbag 309 has good ductility, and thus the airbag 309 can be stretched so that the airbag 309 can seal woven bags of different specifications. Opening and closing components for adjusting the distance between the airbag support plates 308 on both sides are installed on both sides of the support rod 305.

[0024] It is worth noting that a suction hole 311 is provided on one side of the support rod 305, and a trachea joint 312 connected to the suction hole 311 is fixedly installed on the support rod 305, and an independent dual-channel air pump 313 is fixedly installed on the frame 1, and the air supply joint 310 and the trachea joint 312 are both connected to the independent dual-channel air pump 313 through an air pipe and a solenoid valve. The suction hole 311 can generate suction to the outside through the independent dual-channel air pump 313, so that when the woven bag is installed and the woven bag is not tensioned, the woven bag can be fixed on the support rod 305, and the airbag 309 can be inflated and evacuated through the independent dual-channel air pump 313.

[0025] Furthermore, the opening and closing assembly includes a push rod motor 314 fixedly mounted on the support rod 305, a connector 315 is slidably mounted on the support rod 305, the connector 315 is fixedly connected to the output shaft of the push rod motor 314, and connecting rods 316 are rotatably mounted on both sides of the connector 315, and the connecting rods 316 are rotatably connected to the slide bars 307 on both sides. When the push rod motor 314 is lifted or lowered, the connector 315 can be driven to be lifted or lowered, and then the connecting rods 316 on both sides are driven to rotate through the connector 315, and the rotating connecting rods 316 will push or pull the slide bar 307 to move, and then the airbag support plates 308 on both sides can be driven to move, so that the airbag support plates 308 on both sides are close to or away from each other, so that the airbag 309 is in contact with the woven bag and the opening of the woven bag is sealed.

[0026] The compensation component includes a connection groove 317 fixedly mounted on the slider 302, a support rod 305 slidably mounted inside the connection groove 317, a spring 318 fixedly mounted inside the connection groove 317, and the other end of the spring 318 is fixedly connected to the support rod 305. When the woven bag is tensioned, there is a certain gap at the opening of the woven bag. When the airbags 309 on both sides press the woven bag, the gap at the opening of the woven bag will gradually disappear, and then the woven bag will be stretched. In order to prevent the woven bag from being broken, when the two sides of the woven bag are subjected to tension, the support rod 305 will be driven to move and the spring 318 will be compressed, so that the two sides of the woven bag can have a certain activity space to prevent the woven bag from being broken.

[0027] It is worth noting that the airbag support plate 308 is provided with a flexible telescopic member 3081, a top plate 3082 is fixedly installed on the top of the airbag support plate 308, and the airbag 309 is located below the top plate 3082. When the support rods 305 on both sides move away from each other, the airbag support plate 308 will be stretched. Through the setting of the flexible telescopic member 3081, the length of the airbag support plate 308 can be adjusted, and through the setting of the top plate 3082, when the airbag 309 is affected by the air pressure inside the woven bag, the airbag 309 will not be able to expand upwards, but can only expand in the direction close to the woven bag, so that the greater the air pressure inside the woven bag, the better the sealing effect of the airbag 309 on the woven bag, and the woven bag can be tested for stable sealing.

[0028] On the other hand, the present invention provides a method for detecting the sealing property of a flour woven bag, which is applied to the above flour woven bag sealing property detection device, and the method comprises the following steps: Step 1: Place the woven bag under the two support rods 305, and place the air pipe 208 inside the woven bag, and tighten and fix the woven bag through a tensioning mechanism; Step 2: Seal the opening of the woven bag through the airbag pressing module; Step 3: heating water in the water tank 201, then starting the airtightness detection device 2, and transporting the atomized water vapor to the inside of the woven bag through the airtightness detection device 2; Step 4: Observe whether there is mist seeping out from the surface of the woven bag, and observe the air pressure inside the woven bag through the air pressure sensor 209. If there is no mist seeping out from the surface of the woven bag, the woven bag is a qualified product, otherwise the woven bag is a defective product; Step 5: When the air pressure inside the woven bag reaches the standard, the mist inside the woven bag is absorbed into the water tank 201 through the air return component; Step six: cancel the seal of the woven bag through the airbag pressing module, cancel the tension of the woven bag through the tensioning mechanism, then take out the woven bag, and classify and place the woven bag according to the test results.

[0029] Working principle: When the motor 304 is started, the bidirectional screw rod 303 can be driven to rotate, and the rotating bidirectional screw rod 303 can drive the sliders 302 on both sides to move synchronously in the opposite direction. When the slider 302 moves, it will drive the support rod 305 connected thereto to move, and the support rods 305 on both sides will contact the two sides of the woven bag. By moving the support rods 305 away from each other, the opening of the woven bag can be tightened and fixed. When the push rod motor 314 is in motion, the airbag support plates 308 on both sides can be driven to move, so that the airbag 309 can contact the woven bag and seal the opening of the woven bag. The gas can be delivered into the airbag 309 or discharged from the airbag 309 through the air supply connector 310, thereby making the airbag expand or contract. The expanded airbag 309 will evenly compress the opening of the woven bag, thereby sealing the opening of the woven bag. The mist can be delivered to the air supply pipe 208 by opening the first electrically-controlled valve 207 and the air supply fan 206. The mist can be connected to the woven bag by connecting the air supply pipe 208 to the woven bag, thereby performing a sealing test on the woven bag.

[0030] Embodiment 2, as Figures 1 to 3 As shown, based on the first embodiment, a cooling device is provided at the connection between the water tank 201 and the air pipe 213, through which the water mist is condensed into water droplets, and the water droplets are discharged into the water tank 201 (the cooling device is a prior art and will not be described in detail here).
