Introduction: The instrument is designed according to China's national standard GB/T2679.5-1995 (measurement of paper and paperboard folding resistance), is an opto-mechatronic structure, can automatically count the number of double-folded samples. The instrument uses photoelectric control technology to make the folding collet automatically return after each experiment, which is convenient for the next operation. The instrument has powerful data processing functions: it can not only convert the double fold number of a single sample and the corresponding logarithmic value, but also can count the experimental data of multiple samples in the same group, and can count the values of the same group of samples, * ** Small value, average value and coefficient of variation. These data are stored in the microcomputer and can be displayed through the digital tube. In addition to this, the instrument also has a printing function. Technical Parameters: 1. Measurement range: 0 to 9999 times. 2. Folding angle: 135±2°, 3. Folding speed 175 ± 10 times / min. 4. The width of the folding head is 19±1mm. 5. The radius of the fold is 0.38±0.02mm. 6. The spring tension is 4.91~14.72N, and the spring is compressed by at least 17mm for every 9.81N. 7. The distance between the folds is 0.25, 0.50, 0.75, 1.00mm.
