[0042] The working principle of the utility model is:

[0043] In use, the PTFE shaped strip to be measured can be introduced into the positioning frame 5 through the feed port 3 and the guide port 6. Then, the bolts 8 in the positioning holes 7 are tightened until the bolts 8 contact the two sides of the PTFE shaped strip. The PTFE shaped strip can be clamped by the combined action of the two bolts 8, so that the PTFE shaped strip is suspended and fixed in the positioning frame 5. At this time, the PTFE shaped strip can hang naturally under the action of gravity, which can effectively prevent it from warping or wrinkling during the thickness measurement process, thus preventing local thickness distortion. After the PTFE shaped strip is suspended and fixed in the positioning frame 5, the two laser displacement sensors 13 can simultaneously emit lasers to the two sides of the PTFE shaped strip. After the lasers are emitted to the two sides of the PTFE shaped strip, they are received by the laser displacement sensors 13 after being reflected by the surface. At this time, the distances B1 and B2 from the two sides of the PTFE shaped strip to the two laser displacement sensors 13 can be measured respectively. 2. The thickness H of the PTFE profiled strip can be obtained by using the known distance A between the laser displacement sensors 13 and the distance between them, which is A-(B1+B2). The entire measurement process does not require contact with the PTFE profiled strip, thus effectively preventing the deformation of the PTFE profiled strip due to external forces such as compression, which could lead to errors in the measured thickness. The slider 14 can drive the measuring frame 12 and the entire measuring mechanism to move up and down along the slide groove 9, so as to adjust the height of the measuring mechanism according to the length of the PTFE profiled strip. After the height of the measuring mechanism is adjusted, the height of the measuring mechanism can be fixed by tightening the nut 17. When the laser displacement sensor 13 malfunctions, the screw 16 can be pulled out from the mounting hole 15 and the guide groove 11 by unscrewing the nut 17, and then the slider 14 and the measuring frame 12 can be removed from the fixed frame 2 for inspection and replacement of the laser displacement sensor 13.
