The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, shown carding machine cotton bar detection device comprises down extruding embossing roller 1, on push embossing roller 2, pedestal 3, extension spring fixed head 4, extension spring 5, last bent axle 6, following d-axis 7, coupling pin 8, elastic coupling 9, angular displacement sensor 10, sensor assembling base 101, cable 11, central processing unit CPU; The described bent axle 6 of going up connects coupling pin 8, and described coupling pin 8 connects elastic coupling 9, wherein:
Last extruding embossing roller 2 bolts are mounted on the front end of bent axle 6; Push the front end that embossing roller 1 bolt is mounted on down d-axis 7 down; Last extruding embossing roller 2 places down on the extruding embossing roller 1;
Sensor assembling base 101 is by being bolted on the pedestal 3, and angular displacement sensor 10 is by being bolted on the sensor assembling base 101, and the rotating shaft of an end of angular displacement sensor 10 is attached to bent axle 6 ends by elastic coupling 9 and coupling pin 8; Angular displacement sensor 10 is connected with cable 11.
The angular displacement sensor 10 of described a kind of carding machine cotton bar detection device passes the signal to the input of central processing unit CPU by cable 11, and the output of central processing unit CPU is sent to control signal from the main input that makes of frequency conversion of mixing well device.
Correlation technique feature of the present utility model is as follows:
Down extruding embossing roller of the present utility model is fixed, on push embossing roller owing to be contained on the crooked axle, can rotate around pivot, make the extruding embossing roller and push embossing roller down by extension spring to be in tension all the time.Sliver passes between last extruding embossing roller and following extruding embossing roller, the thickness of sliver causes the extruding embossing roller and produces folding between the extruding embossing roller down, and the thickness of sliver causes that going up bent axle produces rotation and determined the angular dimension that last bent axle rotates.The angular displacement sensor that links to each other with last bent axle feeds back to the CPU of main frame according to the high accuracy direct current detection signal of the size generation of different rotational angles, CPU handles through signal and goes to control that the master of frequency conversion makes input in the evereven, what of control cotton instantaneous feeding, thereby make the sliver that comes out on the carding machine remain at the neat and well spaced degree of same thickness, improve the sliver quality, had very high accuracy.
Detection characteristics of the present utility model are that traditional extruding embossing roller straight-line displacement of going up detects, and change into Angular Displacement Detecting by last bent axle and angular displacement sensor, drive the angular displacement sensor rotation, improve and detect stability and reliability.
When the carded sliver by last extruding embossing roller and following extruding embossing roller, carded sliver weight or thickness change bent axle are rotated, its angle displacement amount is delivered to angular displacement sensor by coupling pin and elastic coupling, angular displacement sensor is followed rotation, its output signal of telecommunication is direct current 0-10V, this signal of telecommunication is input in the evereven as carded sliver detection signal, thereby regulates carded sliver weight and thickness.Extension spring plays to reset goes up the bent axle effect, and coupling pin works to be connected upward bent axle and angular displacement sensor with hookup.
Angular displacement sensor is provided by U.S. SCHAEVITZ SENSORS company, and model is RVIT-15-60-2631, measurement category 0-5 degree.Because it is all very accurate to participate in the embossing roller of extruding up and down and the last bent axle of detection, makes the angular displacement sensor linear precision be better than 0.25% accuracy standard, so the utility model precision can satisfy 1% accuracy standard of carding machine evereven fully.In addition, compare with linear displacement transducer, the utility model angular displacement sensor vibration proof jamming performance is good; It is that differential transformer form and amplifier integrate that angular displacement sensor detects principle, and its service life and reliability are all fairly good, and volume is urinated in installation.
