Abstract
Disclosed is a test board for a tensile characteristic of a flue-cured tobacco leaf. The test board comprises a stand, a fixed clamping device, and a movable clamping device, wherein the fixed clamping device comprises a clamping stand I fixed on the stand, a lower fixed board I fixed on the top of the stand, an upper fixed board I matching the lower fixed board I and clamping one end of a to-be-tested tobacco leaf, and a fixed bolt I. The fixed bolt I passes through the clamping stand I and enables the upper fixed board I to be tightly pressed and adhered to the lower fixed board I, so that one end of the to-be-tested tobacco leaf is tightly clamped through matching the upper fixed board I with the lower fixed board I. According to the invention, the fixed clamping device matches the movable clamping device to tightly clamp two ends of the tobacco leaf. When the movable clamping device moves, the tobacco leaf is gradually tensioned, and a tension sensor connected to the movable clamping device can accurately measure the tension that the tobacco leaf bears at this moment and outputs a tension value to form a tension curve. When the tobacco leaf fractures, the tension value reaches a maximum value, and the maximum value is the maximum value of the tensile characteristic of the tobacco leaf. The test board is simple to operate, and the detection result is relatively accurate.
