Embodiment Construction
[0017] see figure 1 and 2 , the invention relates to an online nanofiber film thickness measurement device, which is equipped with an air pump 1, an air filter 2 (thread specification: G1 / 4), a fixed value pressure reducing valve 3 (AR2000), and a throttle valve 4 ( LSA8 regulating valve, diameter: 8mm), HVFF8 pneumatic switch valve 5, cylinder 6, pressure sensor 7 (measurement range: 0-2.5KPa), data acquisition and processing system 8, working platform 10, lifting rod 11, screw rod 12, Polished rod 13, support net 14, sealing ring 15. The gas output by the pneumatic pump 1 passes through the air filter 2, the fixed value pressure reducing valve 3, the throttle valve 4 and the pneumatic switch valve 5 respectively in order to obtain the predetermined pressure gas, and then passes into the cylinder 6, and the lower threaded hole of the cylinder 6 is connected to the air cylinder 6. pressure sensor7. The pressure sensor 7 is connected with a data acquisition and processing sy...

The invention relates to a nanofiber film thickness measuring device, relating to a nanofiber film. It is equipped with air pump, air filter, fixed value pressure reducing valve, throttle valve, pneumatic switch valve, cylinder, pressure sensor, support net, sealing ring, motion mechanism, data acquisition and processing system; the air pump is used to provide air source , the air pressure pump is connected to the air filter through the air guide tube; the fixed value pressure reducing valve, throttle valve, and pneumatic switch valve are connected between the air filter and the cylinder through the air guide tube in turn; the nanofiber film produced online is placed at the bottom of the cylinder and Between the working platforms of the motion mechanism; the pressure sensor is connected to the threaded hole at the lower end of the cylinder block; a through hole is provided on the working platform directly below the cylinder, and a support net is laid on the through hole; the output terminal of the pressure sensor is connected to data acquisition and processing On the input side of the system, a pressure sensor is installed at the bottom of the cylinder. The principle is simple, easy to implement, and can quickly detect the film thickness of a certain part of the nanofiber film, which only takes a few seconds.
Description
technical field [0001] The invention relates to a nanofiber membrane, in particular to a nanofiber membrane thickness measuring device for online detection of the thickness uniformity of the electrospun nanofiber membrane. Background technique [0002] With its superior mechanical, optical and electrical properties, nanofibers are widely used in many fields such as filtration, noise reduction, sensors, protective clothing, drug release, biological scaffolds, flexible electronics and new energy. The key to its industrial application is to realize Batch manufacturing of nanofibers. At present, batch electrospinning technologies that can produce nanofibers on a large scale mainly include drum electrospinning and centrifugal electrospinning. Among them, Czech researchers have developed a "nano spider" device using drum electrospinning technology and successfully commercialized it. The thickness uniformity of the electrospun nanofiber membrane is an important index of the nanofi...
