A kind of polyester staple fiber dry-hot shrinkage on-line measuring device wherein, comprises IR bake and can be installed with specimen holder in IR bake, on this specimen holder with device for detecting length and a plurality of respectively clamper of clamped sample of test sample length.
Further, this specimen holder comprises rectangle stainless steel chassis and specimen holder, and this specimen holder is welded on the stainless steel chassis.
Further, be welded with at least 5 specimen holders on this specimen holder, the distance between the adjacent specimen holder is more than 8cm.
Further, this device for detecting length comprises and is installed in the scalable vertical survey ruler on the specimen holder vertical direction and is fixed on stainless steel crossfoot on the vertical survey ruler that this crossfoot is vertical with polyester staple fiber.
Further, the length of this stainless steel crossfoot is greater than 55cm, and the range of this vertical survey ruler is 0-90cm, and precision is 0.025cm.
Further, the height of each specimen holder is more than the 100cm, its top is welded with the cross bar that horizontal length is 45-55cm, all is welded with at least 8 clampers on each cross bar, and the distance between the adjacent clamper is that the lower tangent plane of 4-5cm and clamper is in the same level height.
After adopting said structure, a kind of polyester staple fiber dry-hot shrinkage on-line measuring device that the utility model relates to, it utilizes a plurality of clampers respectively a sample to be carried out clamping, the length of sample when the recycling device for detecting length detects before and after IR bake is processed, thereby the dry-hot shrinkage of acquisition polyester staple fiber.So the utility model can be realized a plurality of samples of one-shot measurement, greatly improved testing efficiency, and test result is identical with the test result of single sample, thereby has effectively solved the low problem of conventionally test method testing efficiency, has widely dissemination.
