Chinese Patent Application No. be 2012202051076 utility model relate to a kind of tow tension control detection and snubber assembly, specifically, relate to a kind of Cantilevered tension force to detect and snubber assembly, roller is installed on roll shaft by bearing, roll shaft one end to be fixed on slide bar through the slideway of slide plate and vertical with slide bar, and slide bar two ends are each passed through bearing seat, and sensor is fixed on slide plate by sensor holder, sensor and slide bar coaxial cable, arrange spring therebetween.This device is applicable to the tow tension that elasticity is very little as tinsel or carbon fiber and controls, and reduces electric-controlled parts cost, and avoids or reduce the generation of concussion, make tow even running; Detection and buffering are installed together, can structure be simplified, reduce space hold, reduce costs.Adopt cantilever design, facilitate the installation of detected material.
Though above-mentioned two kinds of devices respectively have advantage, but all can not realize continuing or online tension detect or display.
Summary of the invention
Goal of the invention:
Overcome the defect that traditional yarn tension detection device can not carry out continuing to detect, provide a kind of structure simple, test tension detecting apparatus in tow line walking accurately and detection method.
Technical scheme:
Conductive filament roller two ends before silk ribbon (comprising silk ribbon, silk thread, tow) enters crimping machine or yarn swaying machine adopt the bracing frame of one group of cantilever design respectively, often organize bracing frame and contain a link and a support component, link and roller adopt rolling bearing to be connected (to reduce frictional resistance and moment of torsion); Support component is fixedly connected on spinning support, and silk ribbon corner when ensureing to connect (when silk ribbon is by roller guide turning, the angle that the silk ribbon extended line on both sides is formed) is obtuse angle
(preferably
span be 145 °-165 °, to reduce friction force between silk and roller and damage).
Also be connected with one between the link of one group of bracing frame and support component wherein and there is flexible full-bridge type foil gauge, full-bridge type foil gauge is connected to stress display by signal wire, signal wire or be also connected with alarm (sending alerting signal when abnormal numerical value appears in the data of tension force in silk thread).
In the present invention, the long 8-12mm of substrate of preferred full-bridge type foil gauge, wide 4-6mm, the long 4-8mm of sensitive grid; The detection range being applicable to the full-bridge type foil gauge of curl tension (entering tension force in the silk ribbon before coiling machine) is 6-12 newton, and the detection range being applicable to the full-bridge type foil gauge of pendulum wire tension force (entering tension force in the silk ribbon before yarn swaying machine) is 0.1-1 newton.
The stress (silk ribbon is applied to the N that makes a concerted effort on roller) that full-bridge type foil gauge is experienced, with the leading portion tension force F1 in silk ribbon, back segment tension force F2, angle
the angle number of degrees of 1(silk ribbon leading portion and the line of centres, angle
the angle number of degrees of 2(silk ribbon back segment and the line of centres,
2=
-
1) corresponding contact is had, make a concerted effort N and tension force F1, the F2 in silk ribbon can be calculated by mathematical model, directly shown the numerical value of the N that makes a concerted effort that full-bridge type foil gauge is experienced by stress display, and calculated respectively by the calculation procedure that display is built-in and show leading portion tension force F1, back segment tension force F2, angle
1, angle
the numerical value of 2.Make stress display can in real time, Dynamic Announce silk ribbon tension force and full-bridge type foil gauge making a concerted effort of bearing.
In the present invention, support component has two feets, and wherein the length of a feet can regulate.Can, by regulating this feet, to regulate the setting angle of support component on spinning support, the symmetrical center line of support component be made to be positioned on the angular bisector of silk ribbon corner; Now, leading portion tension force F1 and back segment tension force F2 has equal value F, and silk ribbon uniform force, should not rupture.Tension force F in the stress N that full-bridge type foil gauge records and silk ribbon is linear, and make a concerted effort N=F*cos(
/ 2), calculating by arranging simple calculation procedure, can obtain and on stress display, directly show tow and to make a concerted effort each numerical value such as N and tow tension F.
Beneficial effect:
The roller of the cantilever design that the present invention must use in utilizing silk ribbon to run, need not increase too much equipment, and without the need to increasing higher cost, and device takes up room less.The use of full-bridge foil gauge can either realize the tension force of on-line measurement silk ribbon, detects tension force in real time; And can the data problem of Timeliness coverage exception, contribute to the management and control of the quality of production; Silk ribbon is run normally and without any disadvantageous interference, is especially applicable to the silk ribbon use of walking at a high speed.
Wherein the length of a feet can regulate, and is convenient to calculate display and makes a concerted effort and tension values, and simultaneously stressed relatively even, tow is not easy fracture.And employing has flexible full-bridge foil gauge, reduce rigidity vibrations and the noise of roller.
