TECHNICAL FIELD

[0001] The utility model relates to the field of building air-tight waterproof membrane detection, in particular to a kind of building air-tight waterproof membrane air-tightness detection device. BACKGROUND

[0002] The characteristic of air-tight waterproof membrane is breathable and not water-permeable, the aperture is small, the particle size of water droplet cannot pass through, and water vapor molecules can pass through, thereby achieving the effect of waterproof and moisture-permeable. For example, it is applied in building, while strengthening the air-tightness and water-tightness of building, due to its performance advantage, the water vapor in structure can be quickly discharged, the property value is protected, and the problem of moisture-proof is well solved.

[0003] In the production process of air-tight waterproof membrane, the detection of air permeability is an important process, and the air permeable membrane with substandard air permeability cannot achieve the desired effect.

[0004] When detecting the air-tightness of air-tight waterproof membrane, the air-tight waterproof membrane roll produced is generally cut and sampled for detection, which can easily make some local area air-tight waterproof membrane with substandard air-tightness pass through the detection, thereby easily leading to poor use effect of air-tight waterproof membrane.

[0008] Detection mechanism includes air blower, air blower is fixed at the upper end of top plate, air inlet is fixed in the air inlet end of air blower, air outlet is fixed in the air outlet end of air blower, suction pit is fixed in the lower end of air inlet, two first springs are fixed in the wall body inside of the bottom of both ends of suction pit, sliding plate is fixed in the lower end of corresponding two first springs, air outlet is fixed in the lower end of air outlet pipe, two second springs are fixed in the wall body inside of the bottom of front and rear ends of air outlet, sliding frame is fixed in the lower end of second spring, fixed frame is fixed in the rear end of the upper extension plate of front end and the lower end of the upper extension plate of rear end, and marker pen is fixed in the middle of fixed frame.

[0009] Preferably, the bottom of suction pit and air outlet is flat.

[0010] Preferably, the edges of the lower end of air outlet and the edges of the lower end of two sliding plates are rounded.

[0011] Preferably, two bases are fixed to the lower end of the operation table, and a plurality of fixing bolts are arranged in the middle of the bases.

[0012] Preferably, the winding mechanism comprises four rotating shafts, two rotating shafts are rotatably connected to the corresponding ends of the two upper extension plates, and a motor is installed at the input end of each of the two rotating shafts.

[0013] Preferably, a waterproof film roll is arranged between the two corresponding rotating shafts.

[0014] Compared with the prior art, the beneficial effects are as follows:

[0015] When the device is in operation, two rolls of waterproof film are loaded into the winding mechanism, so that the two rolls of pulled-out waterproof film pass between the lower end of the sliding plate and the upper end of the sliding frame and the lower end of the air outlet. Then, the air inlet pipe and the air outlet are started to generate suction force on the waterproof film at the lower end of the sliding plate. When the air outlet generates suction force on the waterproof film at the lower end of the sliding plate through the elasticity of the first spring, the waterproof film can be lifted with the sliding plate in a small amplitude. At the same time, the air outlet and the air outlet generate wind force to blow the waterproof film between the lower end of the air outlet and the sliding frame through the start of the air blower. When the wind force blows on the waterproof film through the elasticity of the second spring, the waterproof film can drive the sliding frame to descend in a small amplitude. Then, the continuous winding of the winding mechanism can make the sliding plate descend and the sliding frame ascend when the air tightness of the passing waterproof film has a problem, so that the waterproof film is lifted and lowered. In this way, the marker pen can draw lines on the part of the waterproof film. In this way, the device can comprehensively detect the output roll of waterproof film and can draw lines on the detected unqualified area. BRIEF DESCRIPTION OF DRAWINGS
