Problems solved by technology

The disadvantage of this approach is that the yarn tension during the hand-held tensiometer test is different from the yarn tension after the tensiometer is removed, and the dynamic tension of the yarn in the test cannot be accurately measured
What exactly was the tension during the test and between measurements? Whether it is stable or not is unknown

Embodiment Construction

[0009] Such as figure 1 As shown, the embodiment of the invention includes the panel 1 of the tester and the path of the yarn 9 on the panel 1 . One of the paths of the yarn 9 is provided with a guide wheel 3 for the yarn 9 to bypass, and the guide wheel 3 is mounted on the connecting shaft 4 through a bearing, and the connecting shaft 4 is fixed to a tester installed on the tester. On the load cell 5; the load cell 5 is connected with the tension display device 2 installed on the tester.

[0010] Starting from the input end, the yarn 9 passes through the tension adjusting device 8, the testing area 10, the guide wheel 3, the roller 7 and the yarn receiving wheel 6 in sequence.

[0011] The force sensors are various small force sensors.

[0012] The force value display device is various display devices that can be used to display the yarn force value detected by the force value sensor.

Abstract

The invention discloses a yarn hairiness testing apparatus with a yarn dynamic tension force measuring display device. A yarn guiding wheel (3) for yarns (9) to pass around is arranged at one position on the pathway of the yarns (9), the yarn guiding wheel (3) is installed on a connecting axis (4) through a bearing, and the connecting axis (4) is fixed on a force measuring sensor (5) which is installed on the testing apparatus; the force measuring sensor (5) is connected with the tension force display device which is installed on the testing apparatus. A yarn tension force detecting sensor on the pathway of the yarns is additionally arranged on the apparatus, and the tension force of the tested yarn is displayed in real time. The yarn tension force is adjusted to the required force value through a yarn tension force adjusting device. The identical yarn tension force can be ensured when the identical yarn is tested, and the accuracy and the consistency of the hairiness testing are improved.

Description

technical field [0001] The invention relates to a yarn hairiness tester, in particular to a yarn hairiness tester with a yarn dynamic tension measurement and display device. Background technique [0002] The yarn hairiness tester using the projection technology method, when testing the yarn hairiness index, gives the number of hairiness of various lengths in a certain length of yarn. It is very important to apply a certain stable tension to the yarn during the test. It has two meanings. First, the length of the yarn is an obvious condition value, and the length of the yarn is different under different tensions. The said yarn length must refer to the yarn length under a certain tension, otherwise it is an uncertain value, which is generally defined in all aspects of yarn length measurement. Therefore, it is necessary to maintain a certain stable tension of the yarn in the hairiness tester. Second, most of the yarn hairiness testers using the projection technology method de...
