Description

For preloading the piezo sensor 5 needle 6 with a spherical} point contact, installed with the possibility of one way with one end with pin sensor 5, and the other end with lever 3, with & 11m by means of a screw 7 with a thread guide 1. The other end of the lever 3 is hinged in the movable frame 8, connected to the frame 9 of the BjHHTOM 10 micrometric machine 10, to adjust the position of the thread guide 1 in the horizontal plane, with the lower side of the lever 3 being concave (see Fig. 2) to maintain the needle in a plane perpendicular to the axis of the piezoelectric sensor 5, which provides the necessary sensitivity of the device. The Pyoelectric sensor 5 with a micrometer screw 11 under the BHJKJio is connected to the frame 8. The curved cross section also has the possibility of rotation and longitudinal movement relative to the geomecricon axis, and a sealed body 12 is transformed rigidly fixed with electrolyte 13, which is occupied by the air gap 1 ...-; m 14 Along the path of re-staining the bubble, a 15p electrode is installed in the vice wire, hollowed into the housing 12. having an insulated section 16 for a half of its length and located along the axis of the housing 12 "Electric circuit of the electrode 15 is powered from the source psrom npohh) of the current 17 and iamenenie sogi.yuch-pvlopi fixed rep1striruyui1im prnboroh ;: 18,

The device works with the installation in the following way: Installation of a nitro-elopik 1 on a given eccentricity relative to the axis of the 1t colicr dipyyuk or coldeck of a single machine in the waves); ere gz; and frame 8 using a micrometer 10.

Under the influence of the etappian power of the yarn filament I31 and 5, 51 a portion of the nit wire of the conductor 1, the air bubble 14 is mixed along the electrode 15, which causes electrolytic resistance in the circuit of the evil 11.10 / 1 and 16, which is recorded by the recording of devices 18, since the bending of the elastic part of the nitro conductor 1 is proportional to the natc / meiuu of the thread, and the failure of the bubble n ;;) 01; og G: 10nally the bending of the elastic part, Thus, by the device 18 or visually, the accumulation of the air bubble can be judged about static nagging thread. The inertness of the electrolyte 13 damps the oscillations of the dusig 14, due to the action of the Dynamic setting of the tension of the jitrrn being tested. This improves the accuracy of measuring the static stress of the HIJI without an additional filter: luch or damping devices;

The implementation of the force-measuring device allows the static tension of the test string to be visually determined.

The viscosity and inertness of the fluid is sharp

reduces the effect of dyne: low tension. With a small change in electrical resistance to increase the signal in the circuit of the electrode 15, adjustment of the length t of the elastic part of the thread conductor 1 is provided.

with a screw, 7, since the bending of the elastic part of the nitroconductor 1 is proportional to the change in the electrical signal.

When the filament moves along a niheprovodnik 1, a dynamic force arises, acting on the piezo-sensor 5 through the lever 3 and 6 and creating an electrical signal in it, arriving at the recording device (not shown). With a small dynamic tension of the thread, it is possible to adjust the amplification of the electric signal by moving the piezo sensor 5 with the needle 6 to the right by the length L along the axis of the lever 3 using m 1crometer1X) screw 11.

Uses of the Invention

It allows precise determination of static and dynamic tension depending on the position of the thread conductor, which contributes to yMaHbmeHtno breakage of the thread and improves the spinning performance.
