The invention provides a short-distance compression strength testing device of paper or a paperboard. The device comprises a first clamping mechanism for fixing one end of the paper or the paperboard,a second clamping mechanism, a driving mechanism and a detection device, wherein the second clamping mechanism is opposite to the first holding device and is used for fixing the other end of the paper or the paperboard; the driving mechanism is used for pushing the first clamping mechanism to be close to the second clamping mechanism; and the detection device comprises a pressure sensor detectingpressure suffered by the second clamping mechanism all the time. The short-distance compression strength testing device of the paper or the paperboard achieves short-distance compression strength testing of the paper or a sheet and is simple in structure, convenient to operate and high in testing accuracy.
Description
technical field [0001] The invention relates to the technical field of strength test device design, in particular to a short-distance compressive strength test device for paper or cardboard. Background technique [0002] Short-distance compression, referred to as SCT, refers to the maximum compression force per unit width that paper and cardboard samples bear when they begin to break, expressed in kN / m; short-distance compression index refers to the short-distance compression strength divided by the quantitative, expressed in N. g said. The test principle is: a 15mm wide sample is clamped between two devices with a distance of 0.7mm and compressed until it fails, the maximum short-distance compression force is measured, and the short-distance compression strength is calculated. Short-distance compression is the latest evaluation method for base paper strength in the world, gradually replacing ring compressive strength RCT. The designed carton compressive strength is predict...
