Abstract

The utility model discloses a yarn hairiness tester with a display device of dynamic tension measurement for yarns. A yarn guide wheel (3) is arranged in the path of a yarn (9) for the yarn (9) to pass. The yarn guide wheel (3) is arranged on the connecting shaft (4) fixed on a force sensor (5) arranged on a tester through a bearing. The force sensor (5) is connected with a tension display device on the tester. A yarn tension detecting sensor is added in the tested yarn path and the tension of the yarn tested is displayed real time. Adjusting the yarn tension in line with the requirement through yarn tension adjusting device can ensure the consistency while measuring the same yarn, thus improves the accuracy and consistency of hairiness testing.

Description

The yarn filoplume tester that has yarn dynamic tension measurement display equipment

Technical field the utility model relates to a kind of yarn filoplume tester, particularly a kind of yarn filoplume tester that has yarn dynamic tension measurement display equipment.

Background technology adopts the yarn filoplume tester of projection counting method, and when the test yarn fibrous index, what provide is the radical of various different length filoplumes in the yarn of certain-length.It is crucial in test process yarn being applied certain stable tension force.Its meaning has two, the first, and length of yarn is a tangible conditional value, the length difference of differential tension yarn under working.Said length of yarn must be meant the length of yarn under certain tension force, otherwise is uncertain numerical value, and this is that all relevant yarn length measurement aspects generally define.So in the filoplume test, will guarantee certain testing length, then must keep yarn that certain stable tension force is arranged.The second, the yarn filoplume tester overwhelming majority who adopts the projection counting method detects the radical of various different length filoplumes in the yarn of the certain-length of Yarn filoplume under state of nature.This filoplume length is meant that filoplume leaves the vertical range of yarn trunk (definition of Yarn filoplume length).Owing to Yarn filoplume is that fiber end is not wrapped in the inner part of exposing of yarn trunk, it is different: have perpendicular to the yarn trunk, the different angle that is that has is attached at the yarn trunk, have straight, have curved, circle or the like arranged.Because yarn has the twist, yarn tension is close with the angular relationship that the yarn trunk attaches to it, and therefore, tension force is relevant with the angle of yarn trunk to Yarn filoplume, the direct filoplume length that records that influences.Once require yarn tension stable in the test; Require yarn tension consistent and stable in the repeatedly measurement with a kind of yarn.Quantity for the various different length filoplumes of a kind of yarn of objective evaluation is significant.How show as when repeatedly measuring the Yarn filoplume index consistency in the test.This just requires the dynamic tension of yarn in the process of test to be consistent.

Past, most of instrument was not measured yarn tension, only adjusted with sensation; Perhaps before test, before yarn enters the instrument test path, measure yarn tension, just no longer measure later on the hand-held tensiometer.The shortcoming of this way is, the yarn tension during hand-held tensiometer test with remove tensiometer after yarn tension different, can not accurately measure the dynamic tension of yarn in the test.Be test process neutralizes, and how much tension force actually when homogeneous is not measured? stable and consistent can't be learnt.

Utility model content technical problem to be solved in the utility model is, a kind of yarn filoplume tester that has yarn dynamic tension measurement display equipment is provided, this instrument fundamentally solves the problem that prior art exists, guarantee that the accurate of yarn tension stablized in the Yarn filoplume test process, thereby guarantee accuracy, stability and the consistance of Yarn filoplume test.

The utility model solve the technical problem the technical scheme that is adopted: a kind of yarn filoplume tester that has yarn dynamic tension measurement display equipment, the path that comprises the panel and the yarn on the panel of tester, be provided with the yarn guiding wheel of walking around for yarn at a place in the path of yarn, on coupling shaft, described coupling shaft is fixed on the force cell that is installed on the tester this yarn guiding wheel by Bearing Installation; This force cell is connected with tension force display device on being installed in tester.

Good effect of the present utility model is: instrument has installed Yarn tension testing sensor additional on the thread path of test, and is presented at the tension force of surveying yarn in real time.Yarn tension is adjusted to the power value that needs with the yarn tension regulating device.Uniform tension in order when the energy assurance is measured with a kind of yarn has improved accuracy and consistance that filoplume detects.

On the other hand, thread path does not strike the beam the filoplume of yarn tested surface.There are two yarn guiding rods that yarn is gently leaned at the two ends, test section during yarn process filoplume test section, reduce influence as far as possible test surfaces filoplume form.And other like product Yarn filoplume test surfaces through the turning yarns of 90 degree to the pressure of yarn guiding wheel be yarn tension  doubly, and overwhelm filoplume, make the filoplume form that bigger variation take place, cause test inaccurate.

The third aspect, the traction of yarn is finished jointly by the roller and the receipts yarn dish of driven by motor.The haulage speed that roller guarantees yarn is accurate with length; Receive the yarn dish and guarantee that yarn does not twine on roller.

Description of drawings Fig. 1 is a structural representation of the present utility model.

Embodiment as shown in Figure 1, embodiment of the present utility model comprises the path of the panel 1 and the yarn 9 on the panel 1 of tester.Be provided with the yarn guiding wheel of walking around for yarn 93 at a place in the path of yarn 9, on coupling shaft 4, described coupling shaft 4 is fixed on the force cell 5 that is installed on the tester this yarn guiding wheel 3 by Bearing Installation; This force cell 5 is connected with tension force display device 2 on being installed in tester.

Yarn 9 is from input end, successively through tension-adjusting gear 8, test section, yarn guiding wheel 3, roller 7 and receipts yarn wheel 6.

Described power value sensor is various small value force sensors.

Described power value display device is the various display device of the yarn power value that can be used to show that power value sensor arrives.
