Abstract
The invention discloses a capacitance type yarn levelness uniformity instrument, which comprises a capacitance pole plate, a capacitance sensor, an analog-to-digital converter and a central processing unit, wherein the capacitance pole plate is connected with the capacitance sensor, the capacitance sensor is connected with the analog-to-digital converter, and the analog-to-digital converter is connected with the central processing unit. The yarn strip thickness change is tested through the capacitance pole plate, the speed is high, and the precision is high.
Description
Technical field
The present invention relates to a kind of measuring instrument, particularly relate to a kind of capacitor evenness tester device of yarn unevenness of strip, rove and the spun yarn that is used to test various staple fibres spinnings.
Background technology
Adopt the mechanical type evenness tester to test the evenness fault of strip and rove in the market; Method of operating is in the groove with strip or rove feeding certain specification; Be added with certain pressure above; Measure the varied in thickness of sliver; The mean range coefficient is represented in the irregularity of measuring every meter sliver commonly used; But the error ratio of the mechanical type uniformity is bigger, and the extreme difference coefficient can not be represented the composition of yarn unevenness structure.
Summary of the invention
Goal of the invention:, the invention provides a kind of capacitor evenness tester device in order to solve the problems of the prior art.
Technical scheme: to achieve these goals, a kind of capacitor evenness tester device of the present invention, it comprises: capacitor plate, capacitance sensor, mould/number conversion, central processing unit; Said capacitor plate links to each other with capacitance sensor; Capacitance sensor links to each other with mould/number conversion; Mould/number conversion links to each other with central processing unit; How right said capacitor plate be.
Operation principle of the present invention is following: the sliver of putting into test usefulness between the capacitor of being made up of two parallel pole plates; Because the dielectric coefficient of sliver is greater than the dielectric coefficient of air; The electric capacity of battery lead plate is increased, and the change value of capacitance is relevant with the actual volume of the sliver of putting into capacitor plate; The detection head of capacitor evenness tester device is to adopt parallel plate capacitor to detect the qualitative variability of sliver, and sliver is through capacitor plate, and capacitance sensor is gathered electric capacity change value, and converts electric capacity change value to the signal of telecommunication; This signal gets into central processing unit, and central processing unit compares analysis with the signal of telecommunication and preset value, and central processing unit is with result's output of comparative analysis then.
Beneficial effect: the present invention compared with prior art has following advantage: the present invention passes through the varied in thickness that capacitor plate is measured sliver, fast in speed, and accuracy is high.
Description of drawings
Fig. 1 is a structural representation of the present invention.
