The drawing force online detection device for the spinning-frame back zone, which is provided by the utility model, can be directly applied in the online detection of drawing force in the back zone of a spinning frame, and particularly meet the requirements of general industries, so that the online detection is not only tailored for particularly measuring drawing force in a laboratory. The drawing force online detection device can randomly position the sensor in the drawing zone, and is very convenient to install and operate.
Description
Technical field
The utility model relates to the online test method and the device of cotton spinning frame back area draft power.
Background technology
Drafting force is meant in drafting process, when the faster fibres of former roller speed motion extracts from the slow speed fiber of later roller speed motion, and the frictional resistance summation that is subjected to.Drafting force and yarn quality have confidential relation, drafting force stable more (fluctuation that is drafting force is more little) in drafting process, and fiber speed change point is concentrated more, and it is good more to become sliver to do.
At present, the method of testing of drafting force roughly can be divided into two big classes: the first kind is jaw formula and feeler sensor type before movable, the principle of this kind method is when drafting force changes, the foil gauge that sticks on the front roller bearing deforms, resistance value changes, change the resistance value that detects into voltage signal by strainmeter, thereby with detected drafting force record and analysis.Second class is to utilize the feeler sensor to be detecting element (elastic beam), and directly contact with fiber strip, the variation of drafting force occurs bending and deformation elastic beam, the foil gauge that sticks on the elastic beam produces corresponding positive negative strain with the variation of drafting force, be converted to voltage signal by dynamic strain indicator, after amplifying, sampling, obtain the value of drafting force.
More than both at home and abroad in the same device achievement in research, majority is special under laboratory condition makes to measure for measuring drafting force, in actual production, be difficult to apply, and mechanism design has certain degree of difficulty, the method of testing more complicated, and the reliability of the sensitivity of drafting force monitoring device and test findings is relatively poor.
The utility model content
The purpose of this utility model provides a kind of spinning frame back area draft power on-line measuring device, detects by the on-line continuous to first break draft district drafting force, obtains the measured value of drafting force; And, can dump to data in the computer Execl document through USB simultaneously and handle measured data and real-time being delivered on the intelligent display instrument of drawing-off change curve.
In order to achieve the above object by the following technical solutions: a kind of spinning frame back area draft power on-line measuring device, comprise intelligent display instrument and signal detection sensor, signal detection sensor comprises carrier base, carrier base is provided with support, support is provided with the sensor support plate, and tension pick-up is fixed on the sensor support plate, and tension pick-up one end is provided with feeler, feeler is between rear roller and front roller, and tension pick-up is connected with the intelligent display instrument by lead.
Be provided with signal amplifier between intelligent display instrument and the signal detection sensor.
Flexibly connect between described support and the carrier base, flexibly connect between sensor support plate and the support.
The groove of the boss of described carrier base workplace and support relevant work face matches, and the groove of sensor support plate workplace and the boss of another workplace of support match, and the length of groove is all greater than the length of boss.
The utility model spinning frame back area draft power on-line measuring device can directly apply to the on-line testing of spinning frame back area draft power, especially adapts to the general industry demand, is not only to make to measure for measuring drafting force specially under laboratory condition; And the utility model is the position of adjustment of tonicity sensor in draft zone at any time, installs, operates very simple.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, a kind of spinning frame back area draft power on-line measuring device, comprise intelligent display instrument and signal detection sensor, signal detection sensor comprises carrier base 9, and carrier base is provided with support 7, and support is provided with sensor support plate 8, tension pick-up 5 is fixed on the sensor support plate, tension pick-up one end is provided with feeler 4, and feeler is between rear roller and front roller, and tension pick-up is connected with the intelligent display instrument by lead.
Use screw that travel(l)ing rest 7 is fixed on the carrier base 9 of spinning frame headstock one side, and use screw fixedly the back up pad 8 of tension pick-up 5 be fixed on the travel(l)ing rest 7; Travel(l)ing rest 7 can be adjusted according to tension pick-up feeler 4 and fiber strip contact position needs in the position on the carrier base 9 and the position of back up pad 8 on travel(l)ing rest 7.Tension pick-up 5 is screwed on back up pad 8, fiber strip 3 passes through between rear roller 1 and middle roller 2, the feeler 4 of tension pick-up 5 is placed on the yarn 3 in the draft zone, 4 pairs of fiber strips of feeler produce certain pressure, and make fiber strip form certain cornerite on feeler 4.Tension pick-up 5 is fixed on the sensor support plate 8, and is supported by travel(l)ing rest 7 and carrier base 9.Can change the position in the draft zone on the sensor feeler 4 by adjusting travel(l)ing rest 7.Because yarn 3 is subjected to the effect of drafting force, make feeler 4 produce miniature deformations, and the resistance strain gage through sticking on tension pick-up 5 inside is converted into voltage signal and by lead 6 drafting force value and drafting force change curve is presented on the intelligent display instrument.
Concrete operation method is: the first, and when spinning frame is driven spinning, tension pick-up feeler 4 is stretched on the first break draft district yarn 3, and yarn is applied with certain pressure, the screw-driving on the support 7 is with tension pick-up 5 stationkeeping then; Afterwards, connect tension pick-up 5 power supplys, and the intelligent display instrument is joined with it, begin to test after test parameter configures.
Show drafting force test data (1 second-240 seconds time interval is optional) and draw force variation curve on the intelligent display instrument in real time, and be stored in automatically in the built-in internal memory.Also the intelligent display instrument directly can be connected with computing machine by USB test data is gathered.
