TECHNICAL FIELD

[0002] PE film needs to be detected in thickness sometimes after production, and the basic principle is to measure the thickness by using the functional relationship between the thickness and the attenuation degree when the infrared thickness detection probe moves above the film. When measuring, the film vibrates once the film is affected by external air flow due to the lack of supporting mechanism at the bottom of the film, and the data measured has errors, resulting in inaccurate data. Therefore, a film thickness gauge is proposed to solve the above problems. UTILITY MODEL CONTENT

[0034] After the production of the PE film is completed, sometimes the thickness of the PE film needs to be detected. The basic principle of the detection is to measure the thickness by using the functional relationship between the thickness and the attenuation degree. During the measurement, since there is no supporting mechanism at the bottom of the film, once the film is affected by the external air flow, the film vibrates, and at this time, the measured data has errors, and the data is not accurate. However, in the use of the device, the film layer 6 is located between the moving mechanisms 3 on the upper and lower sides, and when the thickness is measured, the hydraulic rods 9 on the upper and lower sides are started to drive the moving mechanisms 3 to move.
