Description

Transforming the tension of the thread, containing the uirugium element, is known. Co-slip and holder and carrying on two upper bridges, for example, strain gauges, a pickup roller with a free horse and two guide rollers on the base.

In the proposed transducer, the regulation of the sensing of the yarn is obtained without distorting the magnitude of the measured tension of the thread. It differs in that it holds, eh with un | Pgim e., The order is zaken; 1en on the novorotio axis, coaxially with the axis of the sensing roller.

FIG. 1 shows a diagram of a transducer for measuring tension on the side; in fig. 2 is the view from the top.

The transducer contains an external element (in the form of a beam), the fastener is cantilevered on the holder 2 external 3 n carrying two surfaces, for example, the tera sensor 4, and the free end 5 mounted on axis 6, and two nanowires. roller 7 on the axis 8. The holder 2 with the elastic element is rotated pivotally on the axis P, secured on the base 10 by a nut // and which is axially coaxially with axis 6,

The pin 12 is set; 1 and the base 10 n is displaced from the rollers 7 in the direction of the movement of 1H1TI Bn from the center of these rollers; Hold 2t | is screwed with screw 13.

When measuring the tension of an unti B, an elastic element / is rotated near ocii b of the pickup roller 5 together with a holder 2, which is closed by a plug 13 moved in aperture a formed by an arc: 1i with curvature ε1 on axis 9.

The magnitude of the component varies depending on the strength of the threadbender B, bending the said element in the working direction,

in the rez.chyat of which the sensibility of the preobrazovatel l changes: with the minimum sensitivity it occupies the position shown in fig. 2 main linne. nri max.chny-piece |) their dash-dotted line. In the first case, the external unit is subject to stretching of the collar, 1U, 1, 1 and the same with the equal tension of the two branches, B, 01, and 5, due to which the upper and lower limits are measured and same. It has an elastic elastic element for stretching, and its npO4iiocTbio is on. The coaxial spacing of the axes 6 and 9 prevents the roller 5 from changing the position of the roller to the roller 7, which serves to bend it npto B, in connection with which the length of the thread section, which is fixed to the alternator, when held. 2 together with uirugim e.: Imemeggy / does not change. The output length, taken from one 13 diagonals of the four-shoulder bridge, corresponds to the measured value of the tension in the thread.

T h e d e m t and d

A tension tensioning device for tensioning a yarn containing an elastic element, closed on the cantilever and non-tips on two surfaces, for example, strain gauges, a pickup roller at the free end and two guides of ro-tics, hardened on the base, This means that, with the aim of ensuring the sensitivity of the sensor is adapted without distorting the value of the measured tension pntn, the holder with the elastic element is fixed on the axis of rotation, coaxially with the axis of the sensing roller.
